agriculture; economy; development introduction many factors are responsible for decrease in production of agricultural products. these include water erosion, poor soil biology, decreased yield reduced plant growth, reduced sustainability and soil degradation among others (newell and ken, 2014). an effort to address the aforementioned problems will have positive influence on all matter and living organisms on earth including soils and plants which are the main interest for agriculturists. soil properties are of high importance in many human activities, such as agriculture, forestry, landscaping, environmental protection, recreation, and civil engineering. soil survey for different applications requires quick and non-disturbing estimations of numerous soil properties, such as salinity, texture, stone content, groundwater depth, and horizon sequences in soil profiles. a perfect assessment of properties of soil is convoluted due to their variability. measurements of soil with a high sampling density is expensive and consumes time because conventional methods of analysing soil for precision agricultural mapping requires mostly disturbing the soil through removal of soil samples and subjecting them to laboratory analysis. this implies that, through the aforementioned practice, the sampling costs would exceed the potential benefits. geophysical methods, conversely, tolerate quick measurement of soil properties, such as electrical conductivity, resistivity, and potential, from surface of soil straight to any depth without disturbing the soil. precision agriculture is the modern practice that allows farmer to make measurements so that he will know the exact deficiency of his land and plants. https://doi.org/10.56556/gssr.v1i1.301 http://www.jescae.com/ global sustainability research www.jescae.com 2 literature review little practice of geophysical methods is done in nigeria for agricultural practice specially to observe soil fertility. some of the available researches include oladunjoye that used ground penetrating radar (gpr) to characterize valley bottom soil at ilora (oladunjoye et al., 2021), yusuf that employed geophysical and geochemical aproaches to investigate ground water quality and soil cultivation viability in mokwa (yusuf et al., 2018) among others. leti described agro geophysical methods to identify soil pipes (leti et al., 2021). we still need to know more about the field and its impact in agriculture. this paper simply focused on describing the commonest geophysical methods applied in agriculture. the choice of method depends on one’s interest. perhaps, some researchers may decide to use multiple methods, interestingly, using multiple methods will add more certainty and efficiency to the result (alhassan et al., 2021). electrical geophysical method electrical resistivity is a geophysical method that uses the electrical properties of soil to infer about the temperature, water content and salt content of the soil. such properties include resistivity and conductivity. there is a relationship between electrical conductivity measured with four-electrode probe and conductivity of soil solution (nadler, 1982). these are given in equations 1 & 2. by ohm’s law, er = k ∆u 1 (1) u=elecrical potential ec = 1 er (2) the method of four-electrode probe was also used for the calculation of further soil properties such as soil water content, soil structure, bulk density, porosity, and texture, stone content, etc. (larisa et al., 2007; oladimeji et al., 2014; yusuf et al., 2018; kayode et al., 2022). in conditions where one or two soil properties have influence on measured electrical properties, electrical conductivity (ec) method can be used to estimate such properties. the resistivity of rocks is much higher (about 104 -1012 ohm m) than that of soil horizons with any texture. therefore, high er will designate the presence of stones in soil profiles irrespective of soil type and geographical region. vertical electrical sounding (ves) method can be used in studying several processes for instance melting, freezing, wetting-drying and solution transport in soils (yusuf et al., 2018). the mobility of electrical charges can increase significantly when the topsoil materials have higher water holding capacity, such as clay and silt, and especially water logging conditions which can also cause significant decrease in er. this implies that complex soil properties influencing plant growth, plant health and yield can be identified and mapped with electrical geophysical methods. (yusuf et al., 2018). the electrical geophysical methods when compared with conventional methods of soil analysis allows the evaluation of groundwater table, salt and stone content, depth and thickness of soil horizons, polluted/disturbed layers in soil profiles, and content with an estimation error (kayode et al., 2022). soil properties influencing density of mobile electrical charges in summary are: • chemical properties (salt content, humus content etc) stones and oil are intrusions of high resistivity. • physical properties (bulk density, water content, temperature, texture, water movement based on soil compaction or mixing) applications of er/ec in agric changes in one soil property can be monitored (dryingwetting, freezing-melting, solution transport) mapping of the soil properties which highly influence electrical parameters (salinity, stone content, hardpan, oil pollution, ground water table) evaluate complex effect of many soil properties on measured electrical parameter, develop management zones or study soil cover structure. (richard and dualem, 2014) electrical resistivity is fast, portable, versatile, affordable and in depth. ground penetrating radar ground penetrating radar (gpr) uses seimic method and serves as a quality control tool to determine the presence, depth and lateral extent of diagnostic subsurface horizons, improve interpretations by providing estimates of different soil types composing a soil map unit and characterize spatial and temporal variations in soil properties (doolite, 2014). gpr generates a sequence of trigger pulses which are sent via a control cable through the antenna. each cable transmits into a bipolar transmit pulse. the transmitted pulses are the directed into the soil by the antenna which is fold below the surface. the energy is radiated in a pattern roughly 90° front to back and 60° side to side. it passes different materials with different properties. the dielectric constant changes when change in electrical conductivity of soil is experienced. some of the pulse bounces back to the antenna. the received signals are then sent back to the receiver where they are processed. the data are displayed on a coloured map and can be stored on internal hard drive for later play back. gpr results depend mainly on two electrical properties of soil namely electrical conductivity and relative dielectric permittivity or dielectric constant. electrical http://www.jescae.com/ global sustainability research www.jescae.com 3 conductivity (ec) is the ability of a material to conduct an electric current. it controls the signal penetration. ec increases with increasing water, clay and size of soil contents (doolite, 2014). on the other hand, dielectric constant is the measure of the capacity of a material to store charge when an electric field is applied to it. it controls the strength of the signal reflection. different subsurface materials have different dielectric constant. three general soil/landscape factors affect water and crop growth : • available water storage (soil texture, organic matter) • rate of water infiltration and recharge (soil surface porosity, layers of impermeability, slope) • water redistribution within the field (relative elevation, curvature, slope) newell kitchen. (barry et al., 2010) electro magnetic method electro magnetic (e-m) wave creates sinusoidal e-m field that induces e-m current. e-m reaches 1km depth and exhibits both time domain and frequency domain techniques. (richard and dualem, 2014). electromagnetic induction (emi) possess the potential in assisting agricultural applications (binley et al.,2015). the method has the ability to provide a suitable alternative by measuring apparent electrical conductivity of soil which can be used to estimate soil properties such as water content, textural properties, mineralization, porosity, and residual pore water content (brogi et al., 2021). remote sensinsing method remote sensing acquires information about an object without making physical contact with that object. remote sensing gives the soil moisture data and helps in determining the quantity of moisture in the soil and hence the type of crop that can be grown in the soil. remote sensing technology plays an important role in the analysis of crop health which determines the overall crop yield. when all of this data is combined it gives almost accurate estimates of the crop yield. because of the predictive nature of the remote sensing technology, farmers can now use remote sensing to observe a variety of factors including the weather patterns and the soil types to predict the planting and harvesting seasons of each crop. remote sensing has also played an important role in crop identification especially in cases where the crop under observation is mysterious or shows some mysterious characteristics (grindgis, 2018). conclusion characterizing soil spatial variability at immediate (field) scale is a major challenge in soil investigation. this paper brought on board the advantage of geophysical methods over other methods in precision agriculture. electrical method, ground penetrating radar and electro magnetic methods are discussed as the most commonly used geophysical methods in agriculture. this allows the observation and recommendation of using the methods more than it has been applied in the farm especially in nigeria. references alhassan, a., a, a., y, a., n, b., & a, h.

housing renovation; housing quality; housing environment; road rehabilitation introduction rehabilitation involves enhancing the quality of deteriorating neighbourhood through improving and maintaining existing infrastructure. the essence of rehabilitation is to prevent infrastructure/properties from deterioration, dilapidation and collapse. rehabilitation of roads basically requires repairs and improvements through reconstruction and recoating of road surfaces (sule, 2005), upgrading and construction of road surfaces that were previously in a state of disrepair (hartoyo, 2013; bassey, eteng and ewah, 2022). holistically, roads play diverse roles in the society that makes it very importance. for instance, in rural areas, roads basically promote agricultural development and productivity (bassey et al., 2022; bassey and eteng, 2022) while in urban setting, roads influence the siting of land uses/developments, housing, markets etc. while roads are largely important in predicting developments, scholars (ajom, etim and bassey, 2022; ajom, eteng and etim, 2022; eteng, 2016) have showed positive relationships between road rehabilitation and property development. eteng (2016) showed that developers are always clamouring for land in accessible area for housing development. ajom et al., (2002a) argued that road is the prime factor on which housing development depend. their study highlighted that without accessibility, it is impossible to survive in the environment, embark on social activities among other. against this backdrop, roads have been recognized as an integral part of the developmental process of regions (aderamo and magaji, 2010). specifically, housing represent a basic need of man. it is more than mere shelter for man. in fact, housing serves as one of the indicators of a person’s standard of living and his place in the society. this justifies why low density areas are characterized by accessible areas. in calabar south lga, the urban renewal drive which started in 1999, brought about the development and rehabilitation of several roads. the road rehabilitation process further triggered development of various land uses include residential housing (eteng, 2016). the level to which the roads have promoted housing renovation has not been studied in available literature. this suggest that there is a gap in knowledge that needs to be filled. against this backdrop, the paper analysed the level to which road global sustainability research 34 global scientific research rehabilitation has impacted on housing renovation in calabar south lga, cross river state, nigeria. literature review rehabilitation involves enhancing the quality of deteriorating neighbourhoods by improving and maintaining existing infrastructure. the essence of rehabilitation is to prevent infrastructure/properties from deterioration, dilapidation and collapse. rehabilitation of roads requires repairs and improvements through reconstruction and recoating of road surfaces (sule, 2005), upgrading and construction of road surfaces that were previously in a state of disrepair (hartoyo, 2013;

n = n 1+n(e)² where; n = sample size, n = finite population, e = level of significance (limit of tolerable error =0.05). in all, a sample of 399 households was taken. the questionnaire were distributed at the household level. analysis and discussions table 1: condition of wall before and after road rehabilitation s/n condition of wall before road rehabilitation after road rehabilitation frequency percentage frequency percentage 1 sound/intact 83 21.3 277 71.2 2 cracking 121 31.1 73 18.8 3 dilapidating 185 47.6 39 10 total 389 100 389 100 source: field survey, 2022 table 1shows the comparison of the walls of houses by respondents before and after the rehabilitation of the road infrastructure. it showed that only 21.3 percent were staying in houses whose walls were sound and intact before the rehabilitation of the road while the road rehabilitation necessitated the upgrading of the walls of the houses of 71.2 percent. furthermore, the numbers of cracking walls were reduced due to the road rehabilitation exercise as seen in the table. as well, dilapidating walls in houses before the rehabilitation of the road were higher compared to the situation after the rehabilitation exercise. from the observations, it may be deduced that the condition of walls in housing units have witnessed improvements. table 2: condition of roof before and after road rehabilitation s/n condition of roof before road rehabilitation after road rehabilitation frequency percentage frequency percentage 1 sound/intact 84 21.6 241 61.9 2 leaking 187 48.1 96 24.7 3 sagging 79 20.3 38 9.8 4 part missing 39 10 14 3.6 total 389 100 389 100 source: field survey, 2022 global sustainability research 36 global scientific research table 2 indicates that before the rehabilitation of the road infrastructure, the condition of the roof tops on buildings were not in good conditions. for instance, 21.6 percent respondents were staying in houses with sound and intact roof tops before the rehabilitation of the road while the figure skyrocketed as 61.9 percent respondents affirmed that their roof tops were upgraded upon after the rehabilitation of the road. equally, 48.1 percent reported that their roof tops were leaking before the rehabilitation of the road. after the road rehabilitation, this figure was reduced as deduced from the opinion of 24.7 percent. furthermore, 20.3 percent roofs were sagging before the rehabilitation of the road but were reduced to 9.8 percent. in addition, 10 percent parts were missing on their roof tops before the rehabilitation of the road while 3.6 percent respondents were residing in housing units with missing parts. from the table, it is obvious that the houses with leaking, sagging and missing parts have also reduced table 3: fencing before and after the rehabilitation of road s/n fencing before road rehabilitation after road rehabilitation frequency percentage frequency percentage 1 fenced 98 25.2 194 49.9 2 not fenced 291 74.8 195 50.1 389 100 389 100 source: field survey, 2022 table 3 shows a significant difference in the extent to which residence set up fences in their compounds before and after the rehabilitation of road. the table indicated that the percentage of residents that stay in fenced compounds rosed from 25.5 per cent before the rehabilitation of the road to 49.9 per cent after rehabilitation. the observations suggest that road rehabilitation drastically increased the level to which fences were set up in properties by house owners. table 4: painting before and after road rehabilitation s/n painting before road rehabilitation after road rehabilitation frequency percentage frequency percentage 1 painted 112 28.8 204 52.4 2 not painted 277 71.2 185 47.6 total 389 100 389 100 source: field survey, 2022 it was revealed in table 4 that the percentage of painted compounds along rehabilitated roads increased from 28.8 percent before road rehabilitation to 52.4 percent after the rehabilitation of the roads. this is because, the rehabilitation of roads drastically encouraged property owners to fix and upgrade their structures since demand for the housing properties became increased. recommendations based on the findings of this study, the following recommendations are made; i. since road rehabilitation manifest positive effects on housing renovation, there is need to ensure regular rehabilitation of roads in the study area ii. rehabilitated roads should also be maintained to avoid collapse faster than anticipated iii. there is need to incorporate public private partners in the rehabilitation process iv. development control should be taken seriously in the study area to ensure that renovation in housing units do not contradict with approved urban development pattern. conclusion this paper analyzed road rehabilitation and housing renovation in calabar south local government area, cross river state, nigeria. it was observed that the rehabilitation of roads leads to the improvement in the conditions of housing units. for instance, the study presented a variation in the quality of building components that were assessed in the appraisal. the variation suggests that housing renovation increased drastically after road rehabilitation. from the findings, it is clear that road rehabilitation is a positive contributor to housing development. thus, amid growing population global sustainability research 37 global scientific research and the attendant need to ensure good quality housing units to shelter people within the study area, good road provision and rehabilitation can be adopted as a strategy that should be used. acknowledgement: none funding: none conflict of interest: the authors declare no conflict of interest references adebayo, m.

(2004) reported of pollution of streams, well-water and soil with cadmium, chromium, copper and nickel by a brewery industry https://doi.org/10.56556/gssr.v1i1.298 http://www.jescae.com/ mailto:umanaedo@yahoo.com global sustainability research www.jescae.com 6 located in ibadan, oyo state, nigeria. it is quite glaring that effluent discharged into surface water, underground water and soil from brewery plants is capable of causing pollution. brewery effluent is comprised of wastewater from washing bottles, water treatment plant, carbon dioxide generating plant, bottling and production hall and general wastewater from domestic washing. losses in beer production process and the clean-in-place (cip) located in the brewery house, cellar house and bottling house also form part of the effluent from brewery plants (techobanoglous et al., 1991). untreated brewery effluent contains basically, suspended solids in the ranges of 10-60 mg/l, biochemical oxygen demand (bod) in the range of 1000 – 1500 mg/l, chemical oxygen demand (cod) in the range of 1800 – 3000 mg/l and nitrogen in the range of 30-100mg/l (alao et al., 2010). the effluent also contains organic materials such as spent grains, waste yeast, spent hops and grit. the average range of effluent ph is about 7 for combined effluent but can fluctuate from 3-12 depending on the use of acid or alkaline cleaning agent (world bank, 1997). pollutants arising from brewery effluent have the potentials to affect aquatic ecosystem. the productivity and growth of aquatic organisms depend on the physical, chemical and microbiological characteristics of the water body (olagbemide, 2017). maximum productivity of aquatic lives can only be obtained in water with optimal level of physical, chemical and microbiological parameters (olagbemide, 2017). it is therefore very essential and important to test water before it is used for drinking, other domestic agricultural or industrial purposes. therefore, this study was carried out to evaluate the physicochemical parameters and heavy metal concentrations of surface water receiving effluent from champion breweries, uyo and to assess the quality of this water to aid in decision making and policy formulation. materials and methods study area the study was carried out at aka-offot industrial layout in uyo metropolis where champion breweries plc is located. it lies between longitudes 70 55" e 70 56" e and latitudes 50 00" n -50 01" n (figure 1). the area has a humid tropical climate with an annual rainfall ranging from 2500-3000mm and annual mean temperature of about 270c and the relative humidity ranging from 75% to 79%. the topography of the area is low-lying with coastal plain sand as parent material (petters et al., 1989). it has a level to gently undulating topography with a gradient of less than five per cent (tahal, 1979; okoji, 1988). the surface geology is unconsolidated sand formations ranging from coarse to fine sands. water sampling method the water samples were collected using polyethylene bottles that were initially rinsed with 10% hydrochloric acid (hcl) then with the sample water. two samples were collected at each sampling point. one sample was used for physicochemical properties determinations. the other sample was for heavy metal analysis. nitric acid (hno3) was added in the samples for heavy metal analysis for the preservation of the metals. electrical conductivity, ph, temperature of the samples were determined in the field using standard equipment (century water analysis kit). the collected samples were stored in an ice-packed cooler kit and taken to the laboratory for analysis. the samples were collected in both wet and dry seasons. a total of 18 samples were collected at 9 locations in each season for laboratory analysis. laboratory analysis in the laboratory, analysis was done by volumetric analysis using standard methods given in apha, (1992). atomic absorption spectrophotometer unicam model 93 was used in carrying out heavy metal analysis using whitehead (1979) method. results and discussion physico-chemical properties physical parameters the physical parameters of the surface water of the study area for both dry and wet seasons are presented in table 1 temperature the temperature of the surface water in the study area varied from 30.0 to 37.0 0c with a mean of 35.1 0c in the dry season and 32.0 to 37.10c with a mean of 33.9 0c in the wet season. mean temperature was higher in the dry season than wet season. there was no significant difference (p < 0.05) in temperature between the permissible limit and that of the surface water during both wet and dry seasons in the study area... temperature affects the amount of dissolved oxygen in water, rate of photosynthesis in plant, the metabolic rate of aquatic animals and so on. the moderate temperature of the surface water in the study area could be attributed to the temperature of the environment (gupta et al., 2003). turbidity the turbidity of the surface water within the study area varied from 304.0 to 910.0 ntu with a mean of 668.9 ntu in the dry season and 250.0 to 1702.0 ntu with a mean of 756.6 ntu in the wet season. mean turbidity http://www.jescae.com/ global sustainability research www.jescae.com 7 was higher in the wet season than dry season. mean turbidity of the surface water of the study area was significantly higher (p <0.05) than the permissible limit of 5.0 for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. turbidity is a measure of the ability of light to pass through water. it measures water’s murkiness which gives an estimate of suspended solids in the water. high turbidity prevents sufficient light from entering the water for photosynthesis by submerged plants (gupta et al., 2003). the high turbidity in the study area could be attributed to the effluent discharged into the surface water by champion breweries plc. figure 1: map of akwa ibom state showing champion breweries plc, uyo (study area). source: agate geographic services (2008). chemical parameters the chemical parameters of the surface water of the study area for both dry and wet seasons are presented in table 2. ph the ph of the surface water in the study area varied from 5.23 to 5.52 with a mean of 5.5 in the dry season and 5.49 to 6.79 with a mean of 6.5 in the wet season. mean ph http://www.jescae.com/ global sustainability research www.jescae.com 8 was higher during the wet season than dry season. this means that the surface water was more acidic in the dry season than wet season. mean ph of the surface water of the study area was significantly lower (p <0.05) than the permissible range of 6.5-8.5 for drinking water (nigerian standard for drinking water quality, 2015) during the dry season but no significant difference from the permissible range during the wet season. water ph is the measure of hydrogen ion concentration in water. better fish production is possible in water with ph range of 6.5 to 9.0 (olasoji et al., 2019). the lower ph of the surface water during the dry season than the permissible limit may be attributed to acid cleansing agent in the effluent discharged from champion breweries plc (olasoji et al., 2019). dissolved oxygen (do) the dissolved oxygen of the surface water in the study area varied from 1.20 to 2.20 mg/l with a mean of 1.40 mg/l during dry season and 1.10 to 2.20 mg/l with a mean of 1.52 mg/l during wet season. mean dissolved oxygen was higher during the wet season than dry season. dissolved oxygen is a measure of the amount of oxygen in water. mean dissolved oxygen of the surface water of the study area was significantly lower (p <0.05) than the permissible limit of 6.0 mg/l for drinking water (united states environmental protection agency, 2022) during both wet and dry seasons. the values indicate that the amount of oxygen in the water was not within the permissible limit. the low amount of oxygen in the surface water in the study area could be attributed to organic pollutants, inorganic reductants and other oxidizable substances in the effluent from the champion breweries plc that consumes large amount of dissolved oxygen in the water (olasoji et al., 2019). biochemical oxygen demand (bod) the biochemical oxygen demand of the surface water in the study area varied from 0.00 to 10.8 mg/l with a mean of 6.1 mg/l during dry season and 3.14 to 11.19 mg/l with a mean of 6.6 mg/l during wet season. mean biochemical oxygen demand was higher during the wet season than dry season. biochemical oxygen demand measures the amount of oxygen that bacteria take from water when they oxidized organic matter. it determines the amount of oxygen required for biological oxidation of organic matter with the help of microbial activities. high bod above permissible limit indicated the polluted status of the water. the mean biochemical oxygen demand of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 2.0 mg/l for drinking water (united states environmental protection agency, 2022) during both wet and dry seasons. the high biochemical oxygen demand of the surface water of the study area could be attributed to the organic pollutants from the effluent discharged from the champion breweries plc (olasoji et al., 2019). chemical oxygen demand (cod) the chemical oxygen demand of the surface water in the study area varied from 0.50 to 1.60 mg/l with a mean of 1.24 mg/l during dry season and 0.40 to 0.80 mg/l with a mean of 0.61 mg/l during wet season. mean chemical oxygen demand was higher during the dry season than wet season. chemical oxygen demand is a measure of the oxygen equivalent of the organic matter content of water sample that is susceptible to oxidation by a strong oxidant. it is a measure of combined effect of many industrial pollutants. high cod above permissible limit indicates the polluted status of the water. the mean chemical oxygen demand of the surface water of the study area was significantly lower (p <0.05) than the permissible limit of 150 mg/l for drinking water (united states environmental protection agency, 2022) during both wet and dry seasons. the low chemical oxygen demand of the surface water in the study area could be attributed to the low inorganic pollutant from the effluent discharged from champion breweries plc (olagbemide, 2017). table 1: the physical parameters of the surface water of the study area during dry and wet

biochemical oxygen demand (cod: bod) (biodegradability index) the ratio of chemical oxygen demand to biochemical oxygen demand of the surface water in the study area was 0.20 during the dry season and 0.09 during the wet season. the ratio was higher during the dry season than the wet season. the ratio of chemical oxygen demand to biochemical oxygen demand assesses whether the compounds in water are biodegradable. it helps in monitoring the presence of toxic and non-degradable substances in water. a ratio greater than 100 means that the compounds in water are relatively non-biodegradable and a ratio of less than 10 means that the compounds are relatively degradable. the ratio of chemical oxygen demand to biochemical oxygen demand of the surface water in the study area shows that the compounds in the surface water are relatively biodegradable (olagbemide, 2017). total dissolved solid (tds) the total dissolved solid of the surface water in the study area varied from 151.0 to 276.0 mg/l with a mean of 242.2 mg/l during dry season and 125.0 to 357.0 mg/l with a mean of 203.9 mg/l during wet season. mean total dissolved solid was higher during the dry season than wet season. total dissolved solid is a measure of the amount of dissolved salts in water. salty water conducts electricity more readily than pure water. the mean total dissolved solid of the surface water in the study area was significantly lower (p <0.05) than the permissible limit of 500 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the amount of dissolved salts in the water was not up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). total dissolved solid just like electrical conductivity serves as a tool for assessing the purity of water. ammonium (nh4) the ammonium (nh4) content of the surface water in the study area varied from 0.00 to 12.61 mg/l with a mean of 4.71 mg/l during dry season and 3.19 to 13.05 mg/l with a mean of 6.77 mg/l during wet season. mean nh4 content was higher during the wet season than dry season. ammonium (nh4) is a source of nitrogen in water. high concentration is toxic to aquatic life. the mean nh4 content of the surface water of the study area was significantly higher (p <0.05) than the permissible limit of 0.05 mg/l for drinking water (united states environmental protection agency, 2022) during both wet and dry seasons. the values indicate that the nh4 content in the surface water of the study area was at toxic level. this concentration is toxic to aquatic life. this could be attributed to the effluent discharged into the surface water by champion breweries plc (olasoji et al., 2019). nitrate (no3) the nitrate (no3) content of the surface water in the study area varied from 0.72 to 1.34 mg/l with a mean of 1.1 mg/l during dry season and 0.42 to 0.93 mg/l with a mean of 0.6 mg/l during wet season. mean no3 content was higher during the dry season than wet season. nitrate is a source of nitrogen in water. high concentration causes excessive growth of algae and water weeds. it can contribute to eutrophication in aquatic ecosystem. the mean no3 content of the surface water of the study area was significantly lower (p <0.05) than the permissible limit of 50.0 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the no3 content in the surface water of the study area was not up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019) nitrite (no2) the nitrite (no2) content of the surface water in the study area varied from 0.00 to 0.02 mg/l with a mean of 0.0096 mg/l during dry season and 0.01 to 0.01 mg/l with a mean of 0.0097 mg/l during wet season. nitrite (no2) is a source of nitrogen in water. high concentration could be toxic to aquatic life. the mean no2 content of the surface water in the study area was significantly lower (p <0.05) than the permissible limit of 0.02 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the concentration of no2 in surface water in the study area was not up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). http://www.jescae.com/ global sustainability research www.jescae.com 11 phosphate (po4) the phosphate (po4) content of the surface water in the study area varied from 0.03 to 0.51 mg/l with a mean of 0.42 mg/l during dry season and 0.04 to 0.04 mg/l with a mean of 0.04 mg/l during wet season. mean po4 content was higher during dry season than wet season phosphate (po4) is a source of phosphorus in water. high concentration is associated with eutrophication in water. the mean po4 content of the surface water of the study area was significantly lower (p <0.05) than the permissible limit of 0.5 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the po4 content of surface water in the study area was not up to the level that can cause eutrophication in water (olasoji et al., 2019). sulphate (so4) the sulphate (so4) content of the surface water in the study area varied from 8.08 to 27.9 mg/l with a mean of 23.4 mg/l during dry season and 3.21 to 57.0 mg/l with a mean of 23.6 mg/l during wet season. sulphate (so4) is a source of sulphur in water. high concentration can impair photosynthesis and increase respiration. the mean so4 content of the surface water in the study area was significantly lower (p <0.05) than the permissible limit of 100 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the concentration of so4 of in the surface water in the study area was not up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). a. heavy metal concentrations iron (fe) the iron (fe) content of the surface water in the study area varied from 0.11 to 4.97 mg/l with a mean of 2.75 mg/l during dry season and 0.23 to 1.22 mg/l with a mean of 0.99 mg/l during wet season. iron (fe) content was higher during dry season than wet season. the mean fe content of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 0.3 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the concentration of fe in surface water of the study area was up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). lead (pb) the lead (pb) content of the surface water in the study area varied from 0.03 to 4.62 mg/l with a mean of 3.47 mg/l during dry season and 0.04 to 0.08 mg/l with a mean of 0.057 mg/l during wet season. lead (pb) content was higher during the dry season than wet season. the mean pb content of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 0.01 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during both wet and dry seasons. the values indicate that the concentration of pb in the

during dry season and 0.00 to 0.04 mg/l with a mean of 0.008 mg/l during wet season. the mean chromium (cr) content was higher during dry season than wet season. the mean cr content of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 0.05 mg/l for drinking water (nigerian standard for drinking water quality, 2015) http://www.jescae.com/ global sustainability research www.jescae.com 12 during dry season and below the permissible limit during the wet season. the values indicate that the concentration of cr in the surface water of the study area was up to the level that constitutes danger to human health and aquatic life during dry season but not so during wet season (olasoji et al., 2019). cobalt (co) the cobalt (co) content of the surface water in the study area varied from 0.04 to 7.69 mg/l with a mean of 4.39 mg/l during dry season and 0.03 to 0.05 mg/l with a mean of 0.04 mg/l during wet season. the mean cobalt (co) content was higher during dry season than wet season. the mean co content of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 0.02 mg/l for drinking water (united states environmental protection agency, 2022) during both wet and dry seasons. the values indicate that the concentration of co in the surface water of the study area was up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). manganese (mn) the manganese (mn) content of the surface water in the study area varied from 0.03 to 5.72 mg/l with a mean of 3.62 mg/l during dry season and 0.10 to 0.15 mg/l with a mean of 0.11 mg/l during wet season. the mean manganese (mn) content was higher during dry season than wet season. the mean mn content of the surface water in the study area was significantly higher (p <0.05) than the permissible limit of 0.2 mg/l for drinking water (nigerian standard for drinking water quality, 2015) during dry season and below the permissible limit during the wet season. the values indicate that the mn content in the surface water of the study area was up to the level that constitutes danger to human health and aquatic life during dry season but not so during wet season (olasoji et al., 2019). chronic manganese exposure resulting from inhalation of manganese dioxide over a period of years, attacks the human nervous system (asthana and asthana, 2001). conclusion/ recommendation the study reveals that the temperature of the surface water was within the permissible limit. the average ph of the surface water in the study area was lower than the permissible range for drinking water especially during dry season. this implies that the water was acidic for optimal use by human and aquatic lives. turbidity of the surface water was above the permissible limit in both wet and dry seasons, indicating low light penetration into the water. dissolved oxygen (the amount of oxygen in water) was below the permissible limit, indicating lack of sufficient oxygen in water in both wet and dry seasons. mean biochemical oxygen demand of the surface water was above the permissible limit, indicating high level of organic pollutants in the water. the ratio of chemical oxygen demand to biochemical oxygen demand of the surface water in the study area shows that the compounds in the surface water were relatively biodegradable. total suspended solid in surface water was above the permissible limit, indicating low water clarity. mean total dissolved solid of the surface water was below the permissible limit, indicating low amount of dissolved salts in water. mean electrical conductivity of the surface water was also below the permissible limit, equally indicating low amount of dissolved salts in water during wet and dry seasons. the concentration of nh4 in the surface water was at toxic level. the contents of nitrate, nitrite, phosphate and sulphate were below permissible limits, indicating non-toxic and lack of these nutrient elements in water. the contents of fe, pb, zn, cd, cr co and mn were above permissible levels, implying that these elements were at various toxic levels in the surface water. therefore, the effluent from champion breweries plc is considered to be one of the major sources of pollutants of the surface water in this area, with the tendency of affecting human health, aquatic organisms and soil contamination as well. however, the management of champion breweries plc should as a matter of urgency, improve upon their effluent treatment method by installing anti-pollution equipment for the treatment of their effluent before disposal, which is based on the best available technology (bat). declarations ethics approval and consent to participate

sediment; river ndakotsu introduction heavy metal is a major pollutant in freshwater which may be through daily human activities such as farming, fishing, and domestic activities or from natural source. some heavy metals like cobalt, copper, iron, manganese and zinc are essential for enzymatic activity and in various biological processes. while metals, like cadmium, lead, and mercury, are not known to play important roles in the body and are toxic even in little quantity (looi, et al., 2013; yi, & zhang, 2012; copat, et al., 2013 & shuhaimi-othman, et al., 2010) generally, research on heavy metals is important on two main fronts, from a public health perspective and from an aquatic environment perspective. heavy metals are found in the aquatic environment and can amass laterally with the food chain. moreover, the little quantity of absorbed metals may either be kept for metabolic use for vital organic processes or detoxified to an inactive metabolic level and temporarily or permanently stored in the body (copat, et al., 2013& alina, et al., 2012) a number of environmental factors, particularly physicochemical parameters and water hardness, can contribute significantly to the accumulation of heavy metals in living things to dangerous amounts and harm to the ecosystem (alhassan et al. 2022; kumar, & achyuthan, 2007). substantial metal danger can bring about lower vitality levels and harm blood arrangement, liver, lungs, other crucial organs and kidneys, decreased or harmed focal and mental anxious capacity or even reason malignancy (fernandes et al., 2008). this may result in bio-collection of substantial metals in man utilizing water and eating fish from this waterway. river ndakotsu is the major river that serve as boundary between lapai local government and agaie local https://doi.org/10.56556/gssr.v1i1.304 http://www.jescae.com/ mailto:usmanalhassangabi25@gmail.com global sustainability research www.jescae.com 25 government and is useful to bordering towns and village for irrigation farming, fishing and domestic purposes. however, daily activities around the river by surrounding town and villages may lead to anthropogenic effect this regime of operation go back to farm and availability of fertilizers and chemical for weeds and insecticides provided by government at the affordable prices. this, made it is necessary to monitor the quality and level of heavy metals pollution in the water body, sediment and aquatic species habiting this environment. analysis of heavy metal should be taken in to consideration because metals may be contained in the fish as they feed on the water body. this study primarily aimed at to determine the concentration of some heavy metal in fish, water, and sediment of river ndakotsu. materials and method description of the study area the area being sought that was used in this investigation is river ndakotsu located in lapai local government area of niger state, approximately between latitudes 9°.34”n and longitude 6°.30”e. material and method collection of samples fish, sediment and water samples were collected between the periods of july-sept 2018 from river ndakotsu, lapai, niger state, nigeria. the fish, sediment and water samples collected for analyses of heavy metal were immediately packed in to ice cooled box and transported to ibrahim badamasi babangida university laboratory for identification of fish to species level and further preparation of sediment and water samples collected follows. samples were collected and prepared in triplicates. preparation of the fish sediment and water samples for heavy metal analysis 0.5 gram of fish, 1g of sediment and 50ml were processed with nitric corrosive and perchloric corrosive at proportion 3 to 1. that is, 15ml of nitric corrosive and 5ml of perchloric corrosive were added to 1g of test in an assimilation tube, it was put in a kiedjal warming square and warmed at 150°c until blend explains (turns dreary – this could take 2-3h). refined water was added and resulting to cooling. the samples were analyzed for copper, manganese and magnesium using the atomic absorption spectrophotometer (aas model: accusys 211 usa). data analysis descriptive statistics was used to calculate ranges, means and standard deviations from the data. the differences in mean were compared at (p < 0.05). the package used in the statistical analysis was spss.

(2012), although these figures were much higher than the general guidelines limit of 50mg/kg for zn in food recommended by uk ministry of agriculture, fishes and food (2007). in spite their higher values, these concentrations were statistically significant at p<0.05 and can induce infections. this finding is however in dissimilar with the findings of tabinda et al. (2013). fe, its concentration ranges from 16.04±0amg/kg, 10.85±0amg/kg and 17.62±0amg/kg this finding is however negated by the report of oluseye et al. (2012), who revealed that high concentrations of fe in fish samples could be due to pollution that occur/intake of these polluted particles by the fish samples in the water. mn was found to be the lowest concentration of heavy metals across the three station of the river, ranges from 0.44±0.03amg/kg, 0.33±0.02amg/kg and 0.43±0.03amg/kg and they all have the same significant differences across the three station of the river, this finding is supported by the report of oluseye et al. (2012), who also recorded low concentration for clarias garienpinus and oreochromis niloticus. however, mn fish helps in fish reproduction and normal functioning of nervous system (olowoyo et al., 2011). the findings of this research shows that concentration of mn was significant at p<0.05. cu and pb was found absent across the three station of the rivers. water samples the concentration of zn and fe, was found as the highest range, zn range from (4.08±0.05a), (6.36±0.15a) and (5.06±0.55a) for fe ranges from 3.67±0.41amg/l, 10.2±0a to 2.56±0amg/l having the highest value and were significant at p<0.05. although, station 2 and station 1 had the highest values across the three station and were significant at p<0.05. these concentrations were greater than 0.03mg/l which was http://www.jescae.com/ global sustainability research www.jescae.com 28 the standard concentration of iron in water according to nesrea (2011) for drinking water. based on my finding is due some anthropogenic activities that take place at the river such as washing of cloths, bathing, washing of plate etc. also fertilizer used in agricultural activities and block industries found close to the river also flush down the waste product in to the river causes pollution to the aquatic organism low concentrations mn was obtained, based on this finding they range from (0.67±0.06a), (0.65±0.0.02a) and 0.12±0.6a were significant at p<0.05 except for cu least concentration which was not significant. the report of this research is in line with the findings of tabinda et al., (2013), who reported similar ranges of these heavy metals in their research carried out on riverine water and fishes. according to the approved standard by nesrea (2011). mn is a mineral required by the body in trace amount for manufacturing of enzymes necessary for metabolism. excess amount of it may lead to poor bone formation, impair fertility and also causes death (mergler et al., 2009). cu was found as the lowest range, cu was also found only in station 2 with range of (0.89±0.06b) and absent in station 2 and 3 which their standard concentrations were 3.0mg/l, 2.0mg/l and <2.0mg/l for cu respectively. this signifies low concentration in river ndakotsu lapai, niger state and cannot be consumed at moderate rate with effect of cu, related diseases. although, the metals when consumed at higher rate may lead to liver, kidney and circulatory problems in human being (wachira, 2007). high concentrations observed for mn and fe may render river ndakotsu lapai water undrinkable because they can induce cancer related disease, despite the fact that high concentration were observed for zn. to be at the safer side it is however no recommended for consumption based on the findings of this research. sediment sample heavy metals concentration of river ndakotsu sediment, according to this research cadmium was found only in the sediment of the river and absent in water and fish sample the concentration ranges from 0.17±0.06b in station 2 only and absent in station 1and 3. the concentration of cadmium was found at lowest range all over the three station of the river, concentration of zn, fe and mn was found the highest range from zn (483.3±7.40e), (571.97±3.97f) and (318.8±1.65d) fe range from (3054±22.6c), (10.34±251.8d) and (1474.4±5.60b) then mn range from (233.3±6.14c), (239.4±5.96d) and (56.47±2.60b). this finding is supported by the report of oluseye et al. (2012), in spite their higher values, these concentrations were statistically not significant across the three station and can induce infections. this finding is however in contrast with the report of tabinda et al. (2013). concentration of cu and pb was found at station 1 and 2 but absent in station and also at low range from cu (1.48±°c) and (21.37±0b) cu was statistically not significant pb (11.73±1.67a) and (19.20±0.87a), pb was statically significant. the low concentration for cu. the concentration could be attributed to bioaccumulation of pollutant over a long period of time from other pollutant source. however, low concentrations of pb inhibit inactive transport mechanisms involving atp and also suppress cellular oxidation-reduction reaction (olowoyo et al. 2011). physico chemical parameters of river ndakotsu water this analysis was carryout at the sampling station with the used of equipment such as thermometer, ph meter (manual) and dissolved oxygen meter across the three stations of the river, temperature temperature was found the highest value of 28°c in station 1 and 3, in station 2 it was 26°c which is found at low value. the water quality parameters were within the acceptable range for temperature (swann, 2006). according to federal ministry of environment fme (2006) the temperature of 20 33°c is recommended as permissible limit standard for aquatic life. hydrogen concentration hydrogen concentration (ph) was found the highest value of 8.3m in station 1 follow by 7.8m in station 2 and the lowest value was 6.00m in station 3. the ph can also affect fish health. for most freshwater species, a ph range between 6.5 9.0 is ideal, but most marine animals typically cannot tolerate as wide range ph as freshwater animals, thus the optimum ph is usually between ph 7.5 and 8.5 (boyd, 1998). dissolved oxygen dissolved oxygen (pp/m) in station 1, 7.2 ppm was found as the highest value follow by 6.3 ppm in station 2 and 6.0ppm in station 3 which was found as the lowest value. (fme, 2006) reported the permissible limit standard of dissolved oxygen for aquatic life is 6.8-10 ppm. http://www.jescae.com/ global sustainability research www.jescae.com 29 conclusion from the results obtained from this study, the concentrations of heavy metals (mn, zn, cd, cu, pb and fe.) found in all the water samples are lower than that in the fish sample species and higher in sediment sample than fish sample, this may be as a result of bioaccumulation over a long period of time. the bio-accumulation of some metals in the fish gills were due to polluted water from river ndakotsu containing various municipal wastes from the village inhabitant. recommendation the need for regular checkups of the heavy metal concentrations in river ndakotsu, selected tributaries since the river serves as source of irrigation and fish for the local inhabitants in the study area. vegetation covers of riverine characteristics is pertinent to be established along the river for heavy metal absorption from the water and sediments. references alina, m., azrina, a., mohd yunus, a. s., mohd zakiuddin, s., mohd izuan effendi, h., & muhammad rizal, r.

peter.ayobami.pa@gmail.com received: 10 march, 2023, accepted: 22 march, 2023, published: 23 march, 2023 abstract the characteristic of urbanization, modernization and it effect on the environment has become a disastrous event especially towards the beginning of 20th century (c). researches have shown an excessive exploitation of minerals both on and beneath the earth crust were consume every year for the purpose of construction alone. thus, not only decrease in volume of earth materials but also the impact on environmental thus need attentions. this study observes that the conversion of material; exploitation; energy used during construction; energy associated with heating; cooling; lighting and ventilating commercial buildings have potential consequence on the environment. a selected study of masterpiece building with philosophy of porous structure, which certified leadership in energy and environmental design (leed) in nigeria, was reviewed. finding indicates that conceptual design from the school of thought help in setting reasonable objectives at the designing process stage. also, energy efficient building will reduce wastage of earth materials with alternate source of natural energy, application of natural element other than artificial during building construction and occupancy stage are mitigation strategies to negate aforementioned effect on the environment. conceptual frameworks with composite notions from various domains were explored to include concept of porosity from medicine among others was utilized, acceptable for maximum lighting, cross ventilation and circulations. hence, energy efficiency was achieved which is friendly to the environment. keywords: sustainable building; porosity for fenestration; iconic and modernization; pollution; environmental impact assessment (eia) introduction vernacular building types evolved in response to local availability of resources such as wood, grass, clay, stone (arthur, 1991) and the basic need of shelter for man (adedeji and olotuah, 2011). the discovery of copper, lead, iron and glass which are more efficient in response to structural stability and modern architecture encourages industrial revolution; manufacturing technologies created new opportunities from existing materials and introduced entirely new materials for construction with the help of mass exploitation of fossil fuels from abundant sources of coal, crude oil and natural gas in nigeria but with energy inefficient buildings (raeng, 2007; arthur, 1991). the industrial revolution thus resulted to increasingly construction of mass building and simultaneously urbanization through commercial and industrial organizations (who, 1992; olotuah, 2005, raeng, 2010; amoa, 2012; aribigbola, 2001). building types that evolved includes intensive, massive both in height and width and iconic. environmental protection agency (epa) highlighted ‘significant changes on the surface of the land’ due to construction activity which involves clearing vegetation, excavation, disrupting habitats, changes to drainage patterns and the water table, noise pollution, dust, vibration among others (frn, 2006). according to the united kingdom green building council (ukgbc, 2019) opined that the construction sector uses more than 400 million tons of material each year, much of which has a negative environmental impact due to intensive extraction of raw materials, transporting to manufacturing plant and site, consecutively with generation of waste, energy consumption both in manufacturing and in use. the town and country planning of england and wales regulations (2011) sets out a requirement to carry out an environmental impact assessment (eia) as part of the planning application process for certain projects been large, high magnitude or complex projects basically to ensure that the environmental effects of a proposed project development are properly accessed before consideration (ukgbc, 2019). an eia provides the local planning global sustainability research global scientific research 47 authority with better information about certain types of project, enabling them to make an informed decision about whether permission should be granted or to allow imposition of more appropriate conditions and responsibility purposely to mitigate possible negative impacts (development control department, 2007; frn, 2006; lagos state of nigeria, 2005; vagale, 2000; oyo state of nigeria, 2012; oyo state government of nigeria, 2014; ukgbc, 2019). however, natural forces, element and advantages over time have been encouraged to be utilized and it is the major process to mitigate urban housing design and construction impact on the environment. in the 20c, many buildings became totally dependent on fossil fuel energy to make them habitable. before 21c, buildings must be designed to function with much lower levels of energy dependency (raeng., 2010). natural ventilation is one of the most familiar aspects of energy efficient building design. this work tend to review existing completed construction project that satisfied leed criteria and requirements, to correlate its existing ecosystem friendly expectation thus, to propagate its contribution to knowledge, to encourage springing up of friendly prototype and typology towards safe of the built environment. problem definition impact on the environment of masterpiece development in the urban center takes a cognizance examination of processes, materials and technologies to improve air movement, thermal performance, and control of moisture, ambient energy, light and acoustics during construction, occupancy stage and variably, need to mitigate change in climatic implication on the environment. research has demonstrated that buildings which combine good architecture to include perceptions, beliefs, principles, aims and or school of thought underlying individual's practices and conduct with environmental design can result in significant increase in occupant satisfactions and productivity as regard low energy building (fadamiro, 1998). the aim is to study the impact of masterpiece development on the environment while the objectives of the study are to: i. identify and to select a masterpiece building in nigeria, ii. determine the architectural philosophy of the design process, iii. examine the impacts of such development on the environment, iv. examine significant increase in occupant satisfactions with good architecture of environmentally energy efficient design. background knowledge to philosophy of porosity in design process schön (1990) examines the design process as a situated activity during which designers seek to solve a problem. the conceptual task of a designer is to analyze the problems that require solution and the approach through a framework. steven holl is one of the most influential contemporary american architects, holl as stated in the work of sotirious (2007) implemented porosity as a concept transferred from medicine, biology and organic chemistry in designing the 350-unit student residence named simmons hall at mit as shown in plate 1. holl’s philosophy is identified as porous (sotirios, 2007). review of porosity’s school of thought in simmons hall building sotirious (2007) described the features and location of the simmons hall dormitory that it belongs to a strip of potential new mit buildings along vassar street, in cambridge, massachusetts. the strip forms the vassar street edge along the briggs athletic field, and it is located next to the railroad tracks. the simmons hall is 350 bed residences of 10 stories high, 382 feet long, providing amenities to students such as a 125-seat theater, a night café, a restaurant with an exit to the vassar street. instead of the typical in massachusetts urban brick wall model, the strip was envisioned by architect holl and his architectural team with a “porous” membrane characteristic (sotirious, 2007). during the process of designing simmons hall as shown in plate 1, the features of pores and porous materials were approached. sotirious (2007) explained further that the design concept of porosity was imported from biology, medicine and organic chemistry to transform a “porous” morphology for simmons hall, via a series of design operations. accordingly, building mass of simmons hall was designed to have five large scale recesses, while a system of vertical cavities creates vertical porosity allowing light and air to circulate within the building envelop. moreover, the building facades have a large number of operable sieve-like windows (sotirios, 2007). plate 1: simmons hall student residence at mit showing pores on its facades source: sotirios, 2007 environmental emission performance global sustainability research global scientific research 48 in the early 20c, the modern architectural movement emerged, bringing new forms of building (amao, 2012) that neglected former primitive form and many of these early examples of modernist movement showed little concern about rate of energy consumption, pollution, scope, magnitude, building’s performance and impact consideration to its immediate environment. effect consideration arose after world war ii in response to building’s environmental performance (raeng, 2010). the field saw a strong interest at the time of the energy crisis during 1970s and again now as energy efficiency is becoming more concern in the evolution of buildings. figure 1: building metamorphosis from shelter, house, mansion and masterpiece source: raeng, 2010 vernacular building types evolved in response to local availability of resources (arthur, 1991). the mass exploitation of fossil fuels instigated man to build resource and energy inefficient buildings (raeng, 2010). figure 1, shows the metamorphosis of primitive shelter which is one of the three major necessity of life has opined by adedeji and olotuah (2011), vernacular architecture is the traditional ways of life which simultaneously reflect on human shelter whereas; modern architecture involves revolutionary ideas and styles in art especially, architecture as a reaction to traditional forms; and international style is an early 20c architectural style in the united states and europe that favored the use of simple geometric lines, spacious interiors, materials such as steel, reinforcement concrete, glass, columns, long façade/open window, open space are achievable with aid of technological advancement (adedeji and olotuah, 2011; anthony, 2014; fadamiro, 1998). building impact studies became one of the principal drivers in construction of new buildings for the 21c to meet emerging challenges. hence, the urgent need to reduce mass exploitation of the earth materials, dependence on fossil fuels for energy and resources conservation which are the major steps to reduce effect on the ecosystem. the need for sustainable buildings is important and achievable through application of energy efficiency and natural element (raeng, 2010). however, low energy buildings require a detailed understanding of the natural forces (sun, natural ventilation and other climatic factor) at play. figure 2, shows the building regulations carbon emission and emission relative revision trajectory by raeng. (2010) shows that for domestic sector projects over the periods of 2004 to 2015, there is successful progressive changes in regulation to carbon neutral which is not significant in the building industries thus, need to set a targets for energy efficiency which is carbon reduction to mitigate impact on the environment. figure 2: building regulations carbon emissions source: raeng., 2010. 100

iconic building but relatively tall. that is, this study involves physical investigation of a selected high-rise building by visual inspection, personal interviews with employees occupying this tall building, physical appraisal and deficiencies in the building. questionnaires were distributed to thirty (30) professionals and thirty (30) non-professionals on problems they perceived, associated with masterpiece structure in nigeria and how they can be avoided. the administrations of structured questionnaires included colored photographs of the selected building and questions relating to eco-friendly evaluation and demographic information of respondents. regarding the selection of respondents, the sampling did not pretend to be statistically representation of the population of lagos but preference was given to understanding the energy efficiency expression of the building. information on efficiency element, renewable natural element (sunlight for day lighting, wind for ventilation through control fenestration), exploitation of construction materials, fossil fuel and alternate source of energy, landscaping element and their immediate effect on the environment was investigated while secondary data were collected from library banks to include journals, newspapers, magazines, internet and also from other personnel with information as regard masterpiece buildings. lagos state in nigeria was selected as the study area being the economic stronghold of west africa sub-region and former capital of nigeria. tall, masterpiece and iconic building development in nigeria are noted to be significant in the city. hence, data for this research was collected by visiting a selected high-rise structure in lagos to determine its current status compare to a selected case study of international standard. amongst problems investigated include maintenance, functionality, emergency preparedness, energy efficiency and comfort. tall buildings in the continents, africa and nigeria hierarchically, anthony (2014) noted that most tall buildings of significance were built in the united state of america, some countries across europe and later asian countries. anthony (2014) quoted data published in the 1980s that about 49% of the world’s tall buildings were built in north america and that it has now changed drastically as asia now has the largest share of 32% against north america’s 24% as shown in table 1. table 1: tall buildings per continents region nos. countries percent (%) nos. building asia 20 32.2 35,016 north america 18 23.9 26,053 europe 20 23.7

population of africa had reached 1,022,234,000 hence, proclaimed africa the second most populated continent behind asia and also noted that the continent’s population is expected to reach 1.9 billion by the year 2050 and this will definitely spur developmental challenges especially in the urban cities. massive, tall and masterpiece development begun to spring up to meet the demand of the increased

continent occupies a land area of about 923,768 sq. km and lagos state happened to be former capital with major economic activities in the country also houses majority of the tall, iconic and masterpiece building which are largely attributed to the fact that most of the major financial and governmental activities are conducted in the city (anthony, 2014). ogundeji and fadairo (2018); and ogundeji, fadairo, ogundeji and ekundayo (2022) explained further the urbanization as the movement of people from rural areas to urban areas to experience or acquire different benefits that are rare in the rural milieu. thus, experiences massive influx of citizens from the rural areas in search of greener pasture which also contribute to lagos growth hence, reason lagos is selected as the study area. table 3 shows list of some tall and masterpiece buildings in nigeria with majority located in lagos, nigeria. table 3: list of tall and masterpiece buildings in nigeria s/n name of building

selected masterpiece building in lagos, nigeria susty buildings (2016) opined that heritage place is one of the iconic buildings in nigeria. the selected masterpiece development which is heritage place is located at alfred rewane road, ikoyi,it provides quality office space in the commercial capital of nigeria. plate 2 and plate 3 are pictures describing the building. heritage place is a massive rectilinear modernist building with its office tower spreading on fourteen (14) floors providing over 15,736 square meters (sqm) of offices space ranging from 450sqm to 2,000sqm, 350 parking bays, double volume reception, suspended ceilings, and a cafe/coffee shop. it was completed in the first quarter of 2016 (susty buildings, 2016). laurus development partners was nominated to oversees consortium of consultants including capita symonds uk, ecad architects, ca consultants, morgan omonitan abe and tillyard limited. the main contractor was itb limited which is also one of the leading construction companies in nigeria while the nominated developer, actis and primerose development company which is a private equity firm were also the team behind the completed ikeja city mall, abuja’s jabi lake mall development and 9-floors office property with sustainable features located within the bustling airport city of accra which is in close proximity with kingsway tower, alliance place, b.a.t rising sun, chelsea group hotel and temple tower (susty buildings, 2016). according to susty buildings (2016), actis ensure that the project meets international green and sustainable building standards by attaining a leadership in energy & environmental design (leed) certificate, a sustainable building rating system set out by the united states green building council (usgbc). these features were expected to lead to 30-40 percent reduction in energy consumption, a valuable asset considering high power and energy costs in nigeria. (susty buildings, 2016) plate 2: aerial view of the heritage place building at night time source: susty buildings, 2016 porosity as conceptual framework pore from greek means “a minute opening”. porosity or “the state of being porous” in the context of organic chemistry and the study of plants and animals indicates the existence of small openings. in biology and in medicine porosity is defined as: “the attribute of an organic body to have a large number of small openings and passages that allow matter to pass through” (sotirios, 2007). https://sustyvibes.com/wp-content/uploads/2016/10/heritage-place-224.jpg global sustainability research global scientific research 51 holl’s contextual definition of porosity by sotirios, (2007) was defined as part of “permeability hypothesis” that a porous morphology would produce considerable effects and positive impact on urban and building scale. that is, better air and light circulation, better accessibility and visibility, better communication between interior and exterior spaces. the assembly of the building container was practice by the production of pores, openings, internal channels and cavities. sotirios, (2007) explained further that porosity can be accomplished in four ways: i. first, by creating large-scale recesses of building envelop;

it applies cutting edge technology to fulfill environmental expectations at all time. the façade of the edifice comprises of alternating composite cladding and high quality lowe double glazing on the upper floors reduce need for artificial lighting during the day and hollow fins substituting the floor to ceiling windows on the first five floors which forms the parking space compare to common horizontal we are used to which consume much space (susty buildings, 2016). ukgbc (2019) maintained that leed basically includes a method of rating system for building types around the world with the aim of helping owners, occupants and operators be environmentally responsible and use resources efficiently. thus, table 4 and fig. 3 indicate attributes among other features that were utilized and that categorized the case in stydy to be energy efficient with leed certification. plate 4 shows drop-off point for visitors from which the 5 level multi storey parking could be accessed. plate 5 also shows the reception area, the use of wood has been creatively employed to the ceilings as one advances from reception to the elevator lobby to give a sustainably pleasing experience. plate 4: drop-off zone source: susty buildings, 2016 plate 5: reception area with wooden finishes on the ceiling source: susty buildings, 2016 plate 6: meeting room with folding door partition source: susty buildings, 2016 open space meeting room with partitions by folding door to allow for expansion of meeting space for variety usage whenever desired is shown in plate 6 indicate functionality of the building, the rentable meeting rooms are also located on the ground floor beside the reception. the cafeteria is serviced by a dry kitchen and can be found on the opposite side of meeting area. plate 6 also observes floor to ceiling glazing which provides vista of the outdoor with provisions of an outdoor eating area to improve that experience. mechanical services such as the generator house is also on the ground floor but zoned away from the public areas. plate 7 shows other mechanical facilities such as heating, ventilating, and air conditioning (hvac) plants, exit deck and hydraulic-powered devices are located on the roof level. global sustainability research global scientific research 54 plate 7: showing floors, long window façade, deck housing mechanical facilities and green areas source: susty buildings, 2016 plate 7 also describe the general planning of the facility, service core is placed at the center and comprises 6 lifts for passengers and one lift for goods movement, an escape stair, storage and office spaces for the facility mangers. the centrally placed core actually provides an advantage of arranging all office space with the inevitable wide-view of the outdoor. the characteristic of heritage place after careful review has less environmental impact. hence, the primary features are itemized; the building’s orientation maximizes natural lighting, ventilation and minimizes solar exposure which variably reduces energy requirements for cooling, heating and air quality systems high efficiency glazing and external thermal envelope also reduce demand on cooling requirements (susty buildings, 2016). it is the first leed certified commercial building in nigeria both at design and construction. heritage building also achieved between 30–40% reductions in energy consumption compared to common practice building in lagos (susty buildings, 2016). the use of natural light and natural ventilation to minimize energy demand is also observed. the automatic presence detectors, sensors and high efficiency lighting from technological advancement are milestone achievement as energy efficiency is concern. occupants’ thermal, visual and working comfort is increased by level of indoor air quality through adequate ventilation and quality of materials (susty buildings, 2016). water demand is minimized through rain water harvesting and condensate recovery from cooling units. also, there is provision of water tank to collect or retain discharge of foul and storm water to the local sewers in lugard road (susty buildings, 2016). recommendations measures put in to consideration by the building professionals in the course of heritage building construction and it effect on the environment which consequently made the building an environmental friendly are specifically not limited to the followings; architect philosophy of porosity encourages environmental friendly building with air and light circulation, better accessibility, visibility and better communication between interior and exterior spaces of building. the urgent need to reduce dependence on fossil fuels and massive exploitation of building materials will go a long way to reduces carbon emission impact on our environment. thus, integrating renewable energy such as energy obtainable from the sun, wind, waves, etc. other than energy generated from fossil fuels, thermal for heating water are economical, reliable, with viable technologies and simple application. conventionally, designed buildings priority must be to minimize energy demands in the first place. hence, building should be designed to be naturally ventilated and lighting in architecture. natural ventilation is one of most familiar aspects of energy efficient building design. use façade innovation system that will moderate solar gains and maximize potential for daylight. the use of local knowledge to suit climate through insulation to standards uses of double and or triple glazed windows to prevent drafts which is current of air flow to minimizes heat loss through windows building materials of high thermal mass were used to prevent fluctuation of indoor temperature, to minimize heat loss and the impact on the environment is the energy required to produce materials of high thermal mass. all pipes that were used were insulated purposely to minimize heat loss and gain for hot and cold pipes and the effect on the environment is understanding aspect that the colored insulation could be perceived or interpreted by the individual. position and orientation of windows and light shafts encourage maximum utilization of natural day lighting which is enough to reduce need for artificial lighting thus, with the effect of creating in-door and out-door connection. open-able windows, chimney for stack effect, underground culvert and availability of air inlet are existing features on heritage building which also amount to energy conservation to the milieu. global sustainability research global scientific research 55 thermostat were used to ensure that heat is efficient, stays at a set temperature as ‘heat control’ and can be regulated as conditions change throughout the year. the use of motion sensors for water taps reduces water consumption as taps turn off automatically and simultaneously reduces impact of sewage in to the milieu. also, use of spray taps reduces water and energy used consumption by 80% compared to normal taps. this also yielded water conservation. waterless urinals do not require water supplies, cheap to install with no possibility of damage by frost. in addition, a dual flush or low flush toilet too reduces water consumption from 6l to 4.5l or less per flushing. recently, dual flushing has raised awareness on water consumption rainwater harvesting achievement through provisions of storage tanks and treatment is to collect rainwater to be used for flushing toilets and that has reduces demand for local water supply. collection of water from washbasins and other grey water with necessary minimal treatment if water is not stored for long is used for flushing toilets. there are low wattage light bulbs purposely efficient to reduce energy usage and they variably contribute to less heating of room and less energy consumption. motion sensors on lights reduce energy usage on unnecessary lighting when the occupants are not in the building. door sensors were avoided because no energy would be required for normal doors but sensor door consumes energy. peradventure, doors for disability can be opened by switches for comfort, with little or no support to the disabled. external blinds were used on windows to prevent overheating in summer as reviewed. planting deciduous trees with a good landscape provide shading in the summer and would allow for heat gain in the winter. the location of structure within buildings but other than virgin environment would provide protection from wind, thereby reducing heat loss and the draughts and the effect on the environment is its attraction for other buildings to spring-up. conclusion design process help in setting reasonable objectives at the designing process stage for the purpose of solving a problem (gero, 1998). conceptual frameworks may be composites involving notions from various domains of inquiry (knight, 2005). the concept of porosity was transferred from medicine; biology and organic chemistry in to new urban context hence, aid air and light circulation, better accessibility, visibility and better communication between interior and exterior spaces of building. in order to create new buildings and adapt existing ones to be fit for the 21c, need to be environmental friendly. performance analysis and energy prediction, the architectural design, available resources and with the empirical construction knowledge will help master builders not to construct inefficient buildings whose energy performance falls far below that which we need to achieve (raeng, 2007). government set out in building a greener future (dclg, 2007) that all new homes must be zero carbon from 2016 (uk green building council, 2019). as steps to achieving this target, energy efficiency standards for new homes are to be improved, through building regulations, by 25% in 2010 and 44% in 2013 relative to current 2006 standards. the proposals for amending part l and part f of the building regulations (dclg, 2009) make it clear that a similar trajectory in figure 2 for carbon reduction will apply to non-domestic buildings. in the uk, the 2006 revision to part l of the building regulations (dclg, 2006) in itself required a 25% reduction in carbon emissions over the previous standard. in a bid to mitigate climate change and secure future energy supplies for the purpose of urban development which are masterpiece or massive building with the minimum environmental, social and economic impacts, we must fundamentally popularize green architecture that is, protection of nature, ecology and environment; and to be able to sustain it (fadamiro, 1998; dclg, 2007; raeng, 2010). raeng (2010) opined that the association of energy with heating, cooling, lighting and ventilating commercial buildings accounts for two thirds of the carbon emissions. building must possess such features to optimize physical characteristics of buildings and their systems to balance these energy demands, exploit natural energy and minimize the reliance on artificial energy for environmental friendly in 21c. the heritage place building, ikoyi has positive and less impact on the environment with the low energy consumption and emission, from the design stage to construction stage with less exploration of materials (sand, stone, granite and water) for concrete work of the frame structure (less massive concrete), natural ventilation and lighting to reduce burning of fuel to power plant and appliances, storm water collection to reduce effect of flooding (akintola, 1978), green planting reduces effect of sunlight and global warming (fadamiro, 1998; dclg, 2007), among others. heritage place ikoyi shows that sustainability, environmental friendly design and construction in urban center is feasible in nigeria. energy efficient design can be achieved with collaboration, inter-disciplinary knowledge between the architects, engineers and other related professionals from the onset of the project. by the time the building design has been sketched, the major opportunities for energy conservation which previous studies have shown to have negative impact on the environment would have been captured and mitigated. hence, the man build-up environment would be guaranteed to be friendly. acknowledgement: none funding: none global sustainability research global scientific research 56 conflict of interest: the authors declare no conflict of interests references adedeji, y. m. d and olotuah, a. o.

aqr031891@gmail.com received: 13 october, 2022, accepted: 25 november, 2022, published: 27 november, 2022 abstract the vulnerability of the environment to the risk posed by climate change becomes even more exponential with the rapid phase of the industrial revolution and globalization in the contemporary era. as a key pillar of sustainability, the role of every societal sector is critical in the consummation of environmental equilibrium. this study was carried out to develop a common framework for the programming of green activities in the realm of public safety sectors and to establish standardized indicators for the coordination and complementation of environmental sustainability efforts and initiatives. the study employed a quantitative research design that supports the use of an instrument to explore the constructs and dimensions of environmental sustainability in public safety through principal component analysis (pca) via exploratory factor analysis (efa). the data harbored a 0.964 index on the kaiser-mayer-oldin (kmo) measure of sampling adequacy which implies that the explored constructs are highly correlated. similarly, barlett's test of sphericity demonstrated strong significance with a value of .000, implying that all indicators are factorable. furthermore, the scree plot revealed that there are two (2) dimensions that yielded an eigenvalue that is equal to or greater than 1 (λ=≥1) namely green behavior and sustainable operations. the explored constructs and dimensions are necessary for the development of a model for green policing which can serve as a basis for monitoring and evaluation of environmental law enforcement and environmental sustainability efforts of the public safety sectors. keywords: green behavior, sustainable operations, public safety sectors, indicators introduction in recent years, a wide range of megatrends in the spectra of demographic upheavals, economic and social dynamics fluctuation, technological advancement, and environmental degradation have accelerated global concerns of sustainable development (lefevre et al., 2022). in the environmental landscape, a key tenet of sustainable development, organisms' habitats are diminishing, the capacity to repair biodiversity is dwindling, the climate is changing, invasive alien species are exponentially rising, and natural resources are under unprecedented demand. the world economic forum (wef) report argued that the most significant concerns for the next five years are social and environmental risks. over a 10-year horizon, environmental concerns takes the center stage of the global environment's health. environmental issues and challenges are regarded as the five most serious long-term dangers to the globe, and possibly damaging to people and planet. accordingly, rated as the top three most serious risks relative to environment are climate action failure, extreme weather, and biodiversity loss (wef, 2022). for instance, pollution impacts every part of the earth, affecting our health through the food we eat, the water we drink, and the air we breathe. pollutants such heavy metals and organic chemicals, as well as those used in electrical insulators and flame retardants, have been detected in plant and animal tissues even at the most distant areas like polar ice caps, deep abyssal seas, and high mountains (jamieson et al., 2017). according to the world health organization, environmental causes account for approximately onequarter of all deaths worldwide, or 12.6 million people in 2012, with at least 8.2 million attributable to noncommunicable environmental causes and more than threefourths occurring in just three locations (prüss-üstün et al., 2016). the global dangers report of the world economic forum's in 2018 outlined that six of the ten largest risks that might afflict the world in terms of likelihood and effect are environmental in nature (wef, 2018). existentially, all https://doi.org/10.56556/gssr.v1i2.348 mailto:aqr031891@gmail.com global sustainability research global scientific research 23 sorts of ecosystems and biomes, as well as all the processes and mechanisms that manage the earth system's balance and resilience, are under great stress (aukema et al., 2017; collins, 2018). this phenomenon of worldwide environmental deterioration offers a serious threat to social and economic growth and development, and its consequences necessitate the intervention of public safety or law enforcement. in response to the 1992 earth summit in rio de janeiro, a slew of international accords and national environmental laws are in existence, and they are carried out by environmental regulation and enforcement among public safety and law enforcement organizations. however, since environmental deterioration continues at its sophisticated high, present environmental legislation implementation is not as successful as intended in halting environmental damages (vogel et al., 2016). these limitations are the result of a variety of causes, including limited human capacities, leadership and management, a lack of access to technology, unpredictable economic development, and expansion, and the transboundary character of environmental impacts, among others (baloch et al., 2020; soga & gaston, 2018; unep, 2018). because the implementation of environmental law necessitates adaptation, countries' implementation and compliance practices and strategies shift from relying solely on severe penalties for environmental violations to viewing compliance through criminal sanctions to heed action for substantial compliance (paddock et al., 2017). agenda 21, a global roadmap or blueprint for sustainable development born out of the 1992 united nations conference on environment and development (unced) earth summit and heeded by the philippines through philippine agenda 21, recognizes the importance of public safety law enforcement in enabling legislation to effectively manage the environment and promote sustainable development in full swing. the role of public safety sectors particularly the law enforcers or police is critical in the attainment of environmental sustainability. given this importance, most law enforcement agencies fail to examine the environmental impact of their operations (konyk, 2018). alarmingly, according to the united nations environment programme (2014), environmental deterioration is rising, and the current environmental law enforcement in almost all developing countries of the world is not as effective as may be desired. this can be attributed to constraints in human capacity and access to technology; nationwide push toward poverty alleviation and rapid economic growth; and, most importantly, a lack of knowledge of potential solutions that could be appropriate, or resilient to countries' environmental policing needs (unep, 2014). more so, there is a dearth of study and literature vis-à-vis green policing and environmental sustainability in the parlance of public safety and in the context of public safety sector. evidently, studies on environmental sustainability primarily pitched into the efforts undertaken by educational institutions, businesses and enterprise, and other government institutions, and study on sustainability initiatives, most specifically green policing, is almost nil, if not nothing at all. this study was borne out of the aforementioned realities. as environmental problems worsen, the role of public safety, particularly law enforcement, becomes increasingly important. this study explored the constructs and dimensions of environmental sustainability in public safety, prospecting the concept of green policing as a strategy to complement sustainability and public safety in promoting a green community. literature review legal foundation sustainable development was previously established as a policy in the philippines as early as the 1970s, long before the concept gained international recognition. this is based on presidential decree no. 1151 of 1977, also known as the philippine environmental policy (pep), which urged the broadest range abuse of resources (exploitation), subject to the circumstance that it will not destroy or pose threat to humanity’s health and safety, and that it will not set conditions that are detrimental to country's economy by and large (de guzman, 2012). the philippine strategy for sustainable development (pssd) that was crafted in 1987 is the country's most robust approach for attaining the twin pillars of sustainable development back in the 1980s: economic growth and environmental integrity. during the time, social development did not emerge as a pillar of sustainable development until ten years later, when the philippine agenda 21 (pa21) was established. following the pep declaration came the philippine national strategy for sustainable development framed in 1989 and the action plan for sustainable development, commonly called as philippine agenda 21. the 1989 strategy aimed for economic growth while protecting the country's biological variety, key ecosystem services, and overall environmental quality. the philippine agenda 21 also established parameters for long-term national development and centered economic development on ecological responsibility and improved on the pep by shifting the emphasis from maximum output to "suitable productivity" within the bounds of the physical environment's carrying capacity, in some ways (lasco et al., 2018). clearly, as a response to the 1992 united nations conference on environment and development, also known as the earth summit, the pa21 became the country's national agenda for sustainable development in the 21st century. consequently, in addition to providing enabling policies for economic and environmental sustainability and integrating the concept of sustainable development into the global sustainability research global scientific research 24 framework of governance of the country, the action agenda enshrined in pa21 explicitly highlighted investments in “human and social capital, health, population management, and human settlements, while also acknowledging the need to address” community poverty and other pressing social issues (haque, 2017; howes et al., 2017). today, pa 21 is still used as the pertinent document for the government's sustainable development policy. the philippines has been a pioneer in enacting laws and regulations concerning the environment and natural resources (enr). the government has passed several laws and established agencies over the years to manage, protect, and conserve the country's environment and natural resources (world bank, 2009). the 1987 philippine constitution, which clearly and explicitly regarded the right of people "to a balanced and healthful ecology in accordance with the rhythm and harmony of nature," established the country's commitment to all aspects of sustainability including towards environmental preservation and protection, economic growth and development, and social justice and equity promotion (delloro & gonzalez iii, 2021). the creation of the midterm philippine development plan (mtpdp) 2004–2010 and the country's commitment to the millennium development goals bolstered the sustainable development agenda even more. it recognized five (5) environmental and natural resource sector targets, namely, maintaining self-sustaining and more productive usage of available resources to encourage investments and entrepreneurial spirit; promotion of sustainable mining operations that conform to the principles of sustainability: economic growth, environmental protection, and social equity; reinforcing protection provided to vulnerable and ecologically-fragile areas; ensuring a healthy environment for the people; and preventing the incidence of natural catastrophes in order to save lives and properties (world bank, 2009). following that, in september 2015, the 192 united nations (un) member states including the philippines, made an agreement to pursue efforts in attaining the seventeen (17) sustainable development goals (sdgs) and the associated 169 objectives by 2030. the 17 global goals encompass the sustainability pillars (environmental, social, and economic). the underlying objectives or targets for each goal relate to the sustainable development theme no one is left behind. it was then recognized that the global goals are crucial in the fulfillment of the long-term vision delineated in ambisyon natin 2040 (reyes et al., 2019). the concept of green policing is based on the existence of campaigns and the implementation of environmental laws and programs by the philippine national police in accordance with its core value makakalikasan (proenvironment), which is centered on environmental protection and conservation in order to maintain ecological balance. as per executive order nos. 23 and 26, series of 2011, the department of environment and natural resources (denr) as the primary government agency in charge of conserving, managing, developing, and using the country's environment and natural resources launched the national greening program (ngp) as the agency's banner program in 2011, with the goal of implementing sustainable management of natural resources through resource conservation, protection, and productivity enhancement, as well as consolidating and harmonizing all greening efforts of the government, civil society, and the private sector, among others. through the pnp loi 42-09 (project t.r.e.e.s.) "pulis makakalikasan: 10 milyong puno, pamana sa kinabukasan" project, the denr has collaborated with the philippine national police. other than tree-growing operations as the main focus of pulis makakalikasan, there have also been environmental initiatives such as clean-up drives on the town's streets and coastal regions, as well as beneath the water via pulis scubasureros. the cleanliness of police camps and stations is one aspect of the intensified cleanliness program (icp). these fundamental values and green policing initiatives are expected to be implemented in all police stations around the country. sustainability and its overarching pillars environmental risks are associated with greater rates of violence. this is related to system processes, in which resource scarcity and violent conflict fuel one another, establishing a chain reaction (iep, 2021). rockström et al., (2009) argues that if one environmental problem is not fixed, the other will be adversely affected such that one environmental problem does not remain fixed in its current condition but rather worsens other environmental concerns in a domino effect. for instance, the habitat loss has an impact on agricultural productivity as well. an "indirect" ecological function is the loss of pollinators which results in lower harvests of native pollinators species of plants (nilsson, 2019). when one views sustainability as a three-pronged pillar comprised of the environment, the economy, and society, or as a dualistic connection between humans and the ecosystems they occupy, there should be consensus that maintaining the supply of clean air, clean water, and clean and fertile land is fundamental to a sustainable socioeconomic system. it is evident that creating a sustainable civilization would be hard or impossible without a sustainably suitable environment to offer a resource basis. likewise, a sustainable economy is dependent on a continuous material flow, energy, and natural resources for without it, the economic systems will fail (morelli, 2011). as supported by (gibson, 2010), sustainable development is an ever-changing process. the sustainability of social, economic, and environmental systems is inextricably global sustainability research global scientific research 25 intertwined thus, while building a sustainable development paradigm, possible trade-offs among these three pillars of sustainability must be addressed. extreme event risk and trade-offs between economic growth, social wellbeing, and the environment are examples of environmental sustainability links. environmental sustainability framework for public safety on the level of policies for sustainability, howes et al., (2017) claimed that there is a plethora of new policies, spanning from international treaties to national initiatives, environmental regulations at several levels of the government, regional programs, and even local plans and programs. nonetheless, years of scientific monitoring reveal that the globe is no closer towards achieving environmental sustainability. in fact, the situation is worsening, with policy implementation failure playing a large role. howes and colleagues further stress that multiple literature demonstrates that the inability of environmental policies to achieve their intended goals is related to economic, political, and communicative problems. overlaps between environmental and economic development objectives, insufficient resources to adopt environmental regulations, and inability to meet objectives to various stakeholders are all crucial factors contributing to the nonattainment of environmental sustainability. according to the united nations environment programme, environmental deterioration is rising, and the current environmental law enforcement in almost all developing countries of the world is not as effective as may be desired (holley, 2017; unep, 2014). as environmental problems worsen, the role of public safety, particularly law enforcement, becomes increasingly important thus, environmental law enforcement must evolve. as a result, states have begun to shift their strict enforcement processes and operations away from relying solely on the imposition of strict sanctions for environmental violations or towards viewing punitive measures as just one of the components of a set of actions that national governments must aim to accomplish substantial compliance. as the link between national and international laws on environment becomes more significant and recognized, it is evident that effective and efficient enforcement and implementation of environmental laws is required if international environmental legislation is viewed to be sustainable. unep (2014) also reported that in emerging and transition economies, some of the policy instruments have frequently not transpired in concert with investment in employee capacity, knowledge bases, or equipment due to conflicting priorities. failure to pay enough attention to inspection and monitoring, as well as failure to put processes in place for engaging the regulated community and discouraging infractions, fosters a culture of impunity and undermines the efficacy of environmental legislation and enforcement. the report also suggests that as technology progresses and the world is at its rapid pace, an effective enforcement necessitates executives staying to stay on top of appropriate and updated technological tools and equipment to empower law enforcement officials to fulfill their duties more effectively and efficiently, thus, appropriate training must be prioritized to enhance and upskill the capacity of police agencies. methodology research design this study employed a quantitative technique that promotes the use of a research instrument to determine the indicators of environmental sustainability in public safety and to identify the possible dimensions of green policing as a basis to develop a green strategy for the public safety sectors. the identification of the indicators of environmental sustainability in public safety was validated by key experts from the department of environment and natural resources (denr) and philippine national police region 12. research respondents/locale upon consolidation, the indicators identified were then tested on the respondents who were the police officers in the eight (8) police stations under the general santos city police office (gscpo) that are strategically established to deliver basic police services in all twenty-six (26) barangays of the city. sampling technique the population was established using stratified random sampling, a probability sampling approach in which the researcher divides the overall population into subgroups to represent a population (acharya et al., 2013). this makes it easier for the researcher to glean relevant inferences from the responses. using this sampling strategy, the researcher randomly picked respondents who fit the target group using a confidence interval of 5%. data administration and collection the administration and collection of data were made through digital forms. data analysis the responses obtained were statistically treated and analyzed utilizing exploratory factor analysis (efa) through principal component analysis (pca) to sequentially standardize linked metrics and examine the global sustainability research global scientific research 26 underpinning factor structure of a set of observed variables without attempting to impose a predetermined structure on the conclusion (knekta et al., 2019; suhr, 2006). efa, as the name suggests, explores the latent and manifest constructs or variables. results and discussion kaiser-mayer-olkin and barlett’s test of sphericity the kmo (kaiser-mayer-olkin) index is a statistical test that determines if the correlation between variables is too low for a factor model to be regarded as adequate (watkins, 2018). it is a more accurate measure of factorability since it determines if the correlation coefficients within the data are close enough to zero to indicate that there is at least one (1) latent factor underlying the variables, with 0.50 being the minimum acceptable value ((smyth, r. & jonhson, 2016). table 1 shows the result of the kaiser-mayer-oldin measure of sampling adequacy and barlett’s test of sphericity result for the dimensions of environmental sustainability in the context of public safety. the kmo value of .964 implies that the sample is in high correlations and that the 286 sample size is sufficient for analyzing the dimensions of environmental sustainability. correspondingly, barlett’s test of sphericity showed high significance with its value of .000, which is less than .001, and therefore further implies that all items are factorable (williams et al., 2010). table 1. kmo and bartlett's test scree plot analysis the scree plot is a graphical representation of the total variance of data suited by the total initial eigen value vs the number of components or indicators (frey, 2018). through the scree plot analysis, first step in factor analysis is deciding how many factors to extract in order to produce the most parsimonious (but still interpretable) factor structure. drawing a straight line across the plotted eigenvalues, beginning with the greatest, the last point on this line symbolizes the last factor extracted, with the notion being that any more variation explained beyond this point is meaningless (smyth & jonhson, 2016). the scree plot below reveals that there are two (2) factors or dimensions that yield an eigenvalue that is equal to or greater than 1 (λ=≥1). starting with the initial element, the slope gradually descends until it approaches a semi-vertical horizontal line formation, as shown in figure 1. figure 1. the scree plot constructs and dimensions of environmental sustainability in public safety the result of exploratory factor analysis using principal component analysis (pca) generated two (2) dimensions: green behavior and sustainable operations. tables 2 and 3 underscored the unidimensionality of the constructs by way of determining the base linear combination of indicators through principal component analysis. the dimension of green behavior includes setting aside time during meetings to talk about environmental sustainability strategies; development of an operation plan for promoting environmental-friendly initiatives; expansion of messaging around zero waste and recycling and promoting the same in the community sectors; promotion of staff carpooling by choosing public transport preferably e-jeeps, and use of a bicycle in congested and heavy traffic areas; establishment of secure video/web group conferencing capabilities at all main sites to reduce travel; establishment of green policing network among stakeholders and the community to increase information sharing and foster environmental leadership.; usage of fleet card for monthly fuel consumption to control fuel and maintenance expenses; and the requirement for external stakeholders to electronically submit documents and accept paperless transactions. kaiser-meyer-olkin measure of sampling adequacy .964 bartlett's test of sphericity approx. chi-square 7217.072 df 210 sig. .000 global sustainability research global scientific research 27 table 2. dimension on green behavior and its indicators table 3. dimension on sustainable operations and its indicators green behavior encompasses the promotion of sustainability awareness, education of staff on best practices, and advocacy for sustainability in everyday behaviors. it is also about elevating the profile of sustainability and fostering a green culture. individual choices have varying degrees of relevance when it comes to environmental sustainability. by organizing options such that the greenest alternatives are the default, police stations may essentially assist raise awareness about the benefits of ecologically friendly choices (konyk, 2018). sustainable operations as another dimension covers the implementation of intensified cleanliness policy in the station and police community outpost; continuance of support to the denr national greening program and environmental awareness campaigns like afforestation, planting of trees and gardening and adopt a forest program; implementation of paper use reductions (paperless) such as records digitization and use of electronic approvals for administrative matters, bring-your-own-mug and bringyour-own-container programs, and police uniform recycling program;

konyk, 2018). conclusion as established by the results and findings of the study, green behavior and sustainable operations are the two (2) dimensions yielded through exploratory factor analysis utilizing principal component analysis (pca). green behavior entails elevating the importance of sustainability and promoting a green culture through the promotion of sustainability awareness, employee education on best practices, and advocacy for sustainability in everyday actions while sustainable operations serve as the foundation for the organizational and administrative initiatives undertaken by the public safety sectors to improve the environmental sustainability of their internal and external operations. the explored constructs and dimensions of environmental sustainability in the context of public safety behooves to establish a standard framework of green policing as a prospect strategy toward sustainability. through this, public safety sectors particularly the law enforcers will be urged to prioritize sustainable choices and incorporate sustainability into their daily police operations and routines. more crucially, public safety sectors may take important efforts toward greening their operations by raising their awareness and understanding on environmental sustainability and making the smartest and greenest decision the default option. contribution/originality this research contributes to the breadth of knowledge by providing empirical data and results on the explored constructs and dimensions of environmental sustainability specifically within the bounds of public safety. as an outcome of my independent and original work, i duly acknowledge all the sources from which the ideas have been derived. acknowledgement: none declaration of conflicting interest. the author declares no conflicts of interest in the development of this research work. funding. this research receives no grant from any funding agency in the public, private, or not-for-profit sectors. references acharya, a. s., prakash, a., saxena, p., & nigam, a.

luis santiago santamaria jotty2 1 universidad de la costa cuc, department of energy, barranquilla-colombia 2simón bolívar university, barranquilla-colombia ∗ corresponding author: christian manuel moreno rocha,cmoreno7@cuc.edu.co received: 15 september, 2022, accepted: 29 september, 2022, published: 30 september, 2022 abstract under the current consumption model, the depletion of natural resources, specifically water, is a reality that we will face if we do not promote a paradigm shift: resources can be reused leaving behind the traditional patterns of taking, manufacturing and discarding. under this premise, in recent years, the concept of circular economy, an economic premise interrelated with sustainability has become an alternative for responsible consumption. the objective is to maintain water sources, if possible, through controlled and responsible collection, increase the reduction of consumption through the reuse of the resource and the appropriate and optimal treatment for its return to nature. through research, development and innovation, r+d+i, it is possible to define new schemes for the reuse of water, both for industrial sectors and for local governments; for example, in relation to the management of waste water, which goes from being waste to becoming a resource again. a study of information, bibliometrics and scientometry of scientific articles associated with the circular economy of water resources was carried out to identify research trends in this topic, as well as to establish the parameters of sustainability and governance of this resource. in the management of this resource, certain social, economic, environmental processes, among others, have not been considered, which affects the issue of water governance. in the development of this work, the scopus database (elsevier, b.v., 2021) and the text mining program vantagepoint (search technology, academic version 12.0) were used. 425 records were identified, during the period 2010 – 2021, in which an increasing trend of 83% is observed. the researchers' interest is focused on applications in environmental science and engineering. as for the countries, spain and italy stand out with the highest number of publications. given the growing interest and importance in the subject, it is necessary to establish which models should be adopted to optimize the use of water resources, contributing to the protection of this natural supply, key to the prolongation of life. keywords: circular economy; sustainable; water resources; engineering; cienciometría; energy efficiency introduction the concept of circular economy has been implemented in the business environment and, more recently, in the development of public policies. his forerunner in the academic literature was kenneth boulding, who claimed that the maintenance of human life on earth requires a circular model of the economy. with this perspective, it is understood that the biosphere is a closed system, while there is a limit to its ability to provide and regenerate resources to meet human needs. this concept arises in contrast to the linear economy model of production and consumption, in which there is a high extraction of raw materials, intensive use of energy and excessive generation of waste, which constitute a risk to human health and ecosystems. from this perspective, the planet is seen as an infinite means of supplying resources and each of its phases contributes to the emission of pollutants. the negative externalities of this productive model have had an impact on the degradation of the planet and have increased the inequality and vulnerability of the most marginalized populations the report limits to growth warns for the first time about the consequences of the ecological footprint associated with economic processes and about the carrying capacity of the planet to regenerate. however, the authors claim that it is possible to change this trend by achieving a balance of ecological and economic processes, without affecting the principle that each person can meet their material needs and ensure their individual well-being. in the seventies, the concept of circular economy gained relevance among environmental ecologists, among which nico-las georgescu-roegan, https://doi.org/10.56556/gssr.v1i1.311 http://www.jescae.com/ mailto:cmoreno7@cuc.edu.co global sustainability research www.jescae.com 33 herman e. daly, crawford stanley holling, christian leipert, howard t. odum and josé manuel naredo stand out. through their approaches, these theorists promoted the idea that the waste stream can be reintegrated through closed production cycles (closed circuits) to prevent further extraction and reduce the amount of materials discarded. later, in the early nineties, david w. pearce and kerry turner explained the interdependencies between the ecological and economic system based on four functions of the environment: services, provision of resources, landfill of waste and emissions and life support system (1993). generally speaking, the circular economy involves three fundamental principles (figure 1). water is one of the most valuable and vital resources of the environment, it follows a natural circular model that regulates the flow of water and ensures its quality. however, as proposed in human-managed systems, they follow a linear model of economic growth, where water qualitatively degrades after use, becoming unsuitable for later use by both humans and ecosystems. the stages of a linear system have reached their limits, where the depletion of a number of natural resources and fossil fuels has been demonstrated, from this point, the circular economy must begin to be understood as the intersection of environmental and economic issues that allows the global industry in terms of water resources to obtain water supplies, sustainable and quality for the future, proposes a new model of society that uses and optimizes stocks and flows of materials, energy and waste, and whose main objective is the efficiency of the use of resources. according to , the circular economy is a system where the focus is on the efficient use of resources through the minimization of waste, the retention of long-term value, the reduction of primary resources and closed circuits of products, portions of products and materials within the limits of environmental protection and socio-economic benefits, have the potential to lead to sustainable development and energy efficiency, as in the studies proposed by .(tsalidis et al., 2022)(from bridges et al., 2022)(tsalidis et al., 2022)(hafsi et al., 2022)(petterson et al., 2022)(torres-guevara et al., 2021)(healthy et al., 2021)(díaz-lópez et al., 2021)(hernández et al., 2021; moreno rocha et al., 2022). today, many countries are facing a water security crisis, understood as "the availability of an acceptable quantity and quality of water for health, life, ecosystems and production, along with an acceptable level of waterrelated risks to people, the environment and the economy". among the issues that affect water security, it is important to highlight: the increase in the demand for basic products associated with changes in consumption patterns (greater number of inhabitants, greater energy expenditure, increase in waste generation, pollution, etc.). supply failures (a greater number of inhabitants requires a greater infrastructure adequate to that growth). risks due to extreme hydrological events (due to the absence of adequate contingency protocols).(arteaga et al., 2019)(diaz-perez et al., 2021) figure 1: principles of the circular economy according to , the circular economy in favor of water would generate an offer of innovative products and technologies, as well as the adoption of effective collaboration models for the integration of water reuse, where norms, criteria and standards related to control and quality are established, reaching the consequent emergency of "new water". after the use of water, a new treatment is carried out, in which the complementary treatment units are organized in cyclical processes, capable of promoting the reuse of water or the new water market, to combat its scarcity. in this way, the introduction of reused water in the current consumption model makes it possible to transform the management of water resources from a linear model to a circular model.(cervera et al., 2016a)(cervera et al., 2016b). the world bank (2020) conducted the wastewater report between 2019 and 2020; from waste to resources, in which he addresses the main challenges, opportunities and case studies in latin america on circular economy. the study highlights the value of wastewater as a source of energy and nutrients, as well as an additional source of water, considering that many countries in the region will face crises of economic water scarcity in the medium term. this implies that, despite the high availability of water resources today, the infrastructure will not be sufficient to meet the growing demand.(majchrowska et al., 2022)(cervera et al., 2016c) http://www.jescae.com/ global sustainability research www.jescae.com 34 circular economy and water resources a linear management of water resources contributes to the inefficient and wasteful use of water, increases the use of matter and energy in the phases of water supply among users, increases vulnerability and social inequality in the face of scarcity and affects the degradation of aquatic ecosystems, among many other problems the effects of the linear model on water resources make it necessary to generate technological and management alternatives. the circular model around water resources is presented as a solution that involves the application of sociotechnical tools for the integral solution of these problems(ahmed et al., 2022)(mangmeechai, 2022) the circular economy is proposed as an alternative model of water management, non-obsessive, its implementation depends on institutional support, financial investment for technological innovation, cooperation between key actors and sectors, and the profound socio-cultural transformations around water resources.(dräger et al., 2022). water is a critical resource that, while it can be considered a renewable good, is vulnerable to pressures caused by societies. based on the circular economy perspective, it is necessary to design a closed-loop water management system to meet human needs without compromising the resilience of water-related ecosystems according to ellen macarthur foundation, the principles of the circular economy can be implemented in the management of water systems (table 1).(mohammed et al., 2022; uribe-toril et al., 2022; vyhmeister et al., 2017)(padmanabhan et al., 2022)(sileryte et al., 2022) one of the main problems that can be addressed from the circular economy in the management of water resources is associated with the conditions of quality, governance, availability of the resource and its different types. for the integral solution of these problems, it is necessary to generate technological and management alternatives, whose objective is to close the resource loops and extend their useful life through greater use, reuse and remanufacturing. from the perspective of the circular economy, water reuse is a winning option, the complete wastewater management cycle is a critical component from source to distribution, collection (sewage and sanitation systems (in (raza et al., 2022)(pereira & vence, 2021)(rödl et al., 2022). situ) and treatment for disposal and reuse, including the recovery of water, nutrients and energy.(lambré et al., 2022). taking into account the above, it can be concluded that the circular economy linked to the water and sanitation sector has been having a great research interest under the sustainability approach, its incorporation into the sectoral policy seeks the optimal use of resources (water, energy and nutrients) reducing the impacts on the environment. the processes related to the management of the socioeconomic component and the management of water have a relevant impact on the applicability of the mechanisms of participation and governance of this resource, generating business opportunities that give financial sustainability to the services.(uribe-toril et al., 2022)(yamaka et al., 2022). table 1: circular economy principles applied to water management systems. ((chen, 2022)) principle 1. minimize negative externalities reduce the amount of energy, minerals and chemicals in the operation of water systems relative to other systems. optimize the consumptive use of water within sub-basins in relation to other sub-basins. implement measures that produce the same result without using water. principle 2. keep resources in use improve the management of reserves of different resources (use and reuse of water, energy, minerals and chemicals) within water systems. decrease energy use and resource extraction in water systems and maximize their reuse. optimize the value generated in the interfaces between water service providers and other production systems. principle 3. regeneration of natural capital maximize environmental flows by reducing consumptive and non-consumptive uses of water. preserve and improve natural capital (restoration, pollution prevention, effluent quality, among others). ensure minimal disturbance of natural aquatic

trends and changes in research, a technique called bibliometric analysis is used to determine different patterns related to institutions, topics, countries, and fields, among others. in addition, academic research focused on a specific topic can be quantified over time. the technique consists(vence & lópez pérez, 2021) of the development of a statistical analysis that involves variables such as authors, distribution of journals, keywords and references. for this, certain tools such as network workbench, vosviewer, histcite and citespace are available.(prieto-sandoval et al., 2021). in the present work, the histcite tool was used to perform the statistical analysis, since it has excellent visualization capabilities and is an open access software(hall et al., n.a.). in addition, this tool is directly focused on the study of trends related to scientific research. for the data collection used in the bibliometric analysis, the web of science website was used, since it is one of the main databases used in this type of studies.(serrano et al., 2020) the collected data was downloaded from the web of science on november 22, 2021, ora scientometric analysis of scientific articles indexed in the scopus database (elsevier, b. v., 2021), with the aim of identifying the thematic lines of research of the authors. the following search equation was structured: (titleabs-key ( "circular economy" ) and title-abskey ( "wastewater treatment*" or "water treatment*" or "water reuse" or "waste water recycling" or "water quality" or "water resource*") and pubyear > 2009 y ( limit-to ( doctype , "ar" ) y ( limit-to ( subjarea , "envi" ) ). the specialized text mining program vantagepoint (search technology, academic version 12.0) was used. results and discussions according to the search equation presented above, 425 articles indexed in the scopus database were identified that relate to "circular economy", "wastewater treatment", "water resources" and "water quality", referring to studies in different fields of knowledge, such as environmental sciences are the ones with the highest activity with 43%, while the area of energy and engineering show a very similar interest of approximately 12% each, (figure 2). using the law of solla prices (ec. 1) (de solla price, 1963), the annual growth rate of works related to this topic published from 2010 to 2021 was calculated. according to equation 1, this index was 83.09% with a data correlation of r2 = 0.974. http://www.jescae.com/ global sustainability research www.jescae.com 36 figure 2: distribution of

related to the number of articles published per year (figure 4). in terms of distribution by country at an international level, spain stands out with 74 publications related to the circular economy of the water sector. on the other hand, china and italy present 56 documents indexed in the database, according to the search equation used. at the latin american level, the country that stands out is brazil with 21 publications, while these works are related to sludge mixtures from water treatment plants for energy recovery, in these works circular economy indicators were designed as instruments for the evaluation of sustainability and efficiency in wastewater. the co-occurrence analysis of the keywords allowed to determine the preference in the topic of interest, in this case, the circular economy in the water sector. the free program vosviewer (2021, center for science and figure 4: distribution of scientific production by country between 2010 and 2021 related to the circular economy

studies, leiden university, the netherlands, version 1.6.15), was used to visualize each of the relationships presented by the keywords (figure 5). a cluster of words shows an interdisciplinary work and all the topics studied are, for example, development and evaluation of wastewater treatments (235 records), among which reverse osmosis stands out, bioremediation methods for the recovery of water contaminated with heavy metals, pesticides, agrochemicals, among others. 222 documents are associated with the concept of circular economy, especially the recovery of resources such as energy, nutrients among others and a last group (52 documents) are aimed at the management of environmental sciences and sustainable development. conclusion according to the search equation proposed for this work and the number of records obtained, it can be observed that the concept of circular economy applied to water resources is relatively new. however, it presents a high interest, which is verified through price's law that shows a growth in the number of publications of 83.09% during the period 2010 – 2021, especially in spain and china, countries where researchers develop work on wastewater treatment methods, the use of resources and the recovery of waste recovered from these same waters. to address water circularity, fundamental changes are needed in the way water is managed and valued, one of the current barriers to truly integrating water. the circular economy of water resources in processes is the lack of indicators, parameters and governance, tools that allow achieving the objective of sustainability by providing economic, environmental and social development. the deployment of a circular economy does not depend solely on cities, it also depends on national policies, private sector participation and a favourable innovation ecosystem. test the permanent selectivity of ion exchange membranes that is under research consideration. the linear economy model is not compatible with the sustainable management of natural resources, especially water resources. the principles of the circular economy propose a series of transformations and improvements to reduce pressures on water resources derived from the production, consumption and disposal of goods and services. in addition, it offers the opportunity to improve water management systems and generates development opportunities that have a positive impact on society and ecosystems. the implementation of these principles requires collaboration between producers and consumers, as well as public policies that guarantee the efficient use of materials and energy. it is expected that this work will be of great contribution to future research, which will motivate more scientists from different countries to see in the circular economy a powerful tool in the care and preservation of different energy sources. declaration of concurrent interest the authors state that they have no known competitive financial or personal interest that could have seemed to influence the work re-performed in this article. references ahmed, m., mavukkandy, m. o., giwa, a., elektorowicz, m., katsou, e.,

university, kebri dehar, ethiopia corresponding author: abdi hassen habib; email: abdihassen1170@gmail.com received: 06 february, 2023, accepted: 18 march, 2023, published: 20 march, 2023 abstract: the study looked specifically at household food security, factors influencing people's decisions to participate in productive safety net programs, and the impact of production safety net programs on rural household food security, as measured by calorie intake. primary data were collected from 334 households in four kebeles samples in kebri dehar, the district, using a multistage sampling technique. a binary logit model and a propensity score matching model were used to investigate the factors influencing the decision to participate and their impact on food security, respectively. the age of the household head and the size of the family have a positive effect on the decision to join the household. however, extended contact and distance from the property market had a negative impact on the decision to join. in this study, the nearest neighbor match method (5) was used to estimate the mean treatment effect for those treated. the propensity score matching results also show that the production safety net program has a positive and significant impact on household food security. households participating in the production safety net program have 214.5 kcal/adult/day more than households not participating. the study concluded that there was a significant difference in household calorie intake between participants and nonparticipants. key words: food security; impact; productive safety net program; propensity score matching introduction background of study food security emerged as a concept in the mid-1970s after a number of implications sparked debates about the global food supply and its responsiveness at both the global and global levels (ingela and nagothu, 2017). however, problems such as family or man-woman supply, dietary quality, and environmental sustainability have not been noted (ingela and nagothu, 2017). in terms of food security, ethiopia is one of the poorest international locations in sub-saharan africa. a large proportion of the country's population suffers from chronic and power meal insecurity (anderson et al., 2015). many elements contribute to rural poverty and persistent food insecurity. the important causes of food insecurity in ethiopia are drought and animal diseases, restrained rural infrastructure, a very susceptible agricultural technical base, constrained access to fundamental services, and fluctuating file costs (fisn, 2017). the population's meal insecurity is anticipated to increase from 5.6 million in 2016 to 8.5 million in 2017 (wfp, 2017). food insecurity is often understood in ethiopia in the context of repeated meal crises and famines, and the response to meal insecurity is regularly dominated by the meal emergency response. between 1994 and 2005, nearly 5 million ethiopians were declared "inclined" and "wanting" assistance. however, large proportions of households receive emergency food assistance, participate in community service projects, and no longer go hungry every year; they are, however, frequently food insecure. because of constrained agricultural manufacturing and poverty, they face predictable annual meal shortages. as a result, despite a long history of providing large amounts of food, the safety of their meals has deteriorated over time. instead, reliance on meals as a useful resource has progressively extended over time, as has the wide variety of ethiopians experiencing continual meal insecurity (devereux et al. 2006). the purpose of the safety net program is to reallocate assets to chronically food-insecure households and enhance long-term options for food-insecure households (usaid, 2012). statement of problem the food security program used to be created to tackle the difficulty of meal manufacturing while additionally enhancing people's lives and alleviating poverty. recognizing its significance, the authorities have taken a mailto:abdihassen1170@gmail.com global sustainability research global scientific research 23 number of steps. beginning in 2005, the ethiopian authorities and donor companies carried out a new kind of protection, the productive safety net program (psnp), with ambitions to minimize persistent meal insecurity, asset depletion, and productive funding to overcome long-term meal insecurity (gilligan et al., 2008). the application is aimed at her 8.5 million inhabitants, who make up 10% of ethiopia's population. these human beings are chronically food insecure; 60% of them stay in pastoral areas, and their buying power has decreased due to farm animals' losses. the final 40% are affected by erratic rainfall, which reduces crop manufacturing (wfp, 2017) in the somali region, the ethiopian authorities have prepared to assist negative rural households registered in chronically food-insecure districts. learn about the effect of productive protection internet packages (psnp) on family livelihoods with the help of (mohamed, 2017): babile case discovered that effective internet security programs had a significant impact on the food safety of families. various studies have been performed on the outcomes of psnp in special fields and at exclusive times. the findings of these investigations varied. food safety research, on the other hand, necessitates a multidimensional shift supported by well-informed lookup disciplines. by assessing the influence of psnps on meal safety in rural households, this study contributes to the current body of knowledge. as a result, the goal of this study is to fill knowledge gaps about the factors that influence productive safety net programs determinants and their impact on rural household food security. objective of the study the primary aim of this study was to assess the productive safety net program determinants and their impact on rural household food security in somali regional state: the case of kebri dehar district) ethiopia specific objectives are as follows: 1. to investigate the current food security situation of rural households in the study area. 2. determining the impact of productive safety net programs on food security in rural households 3. assessing the impact of productive safety net programs on food security in rural households significance of the study it was thought that the study's findings will benefit the ongoing rpsnp efforts in rural kebri dahar households to enhance the current state of food security. by adding fresh information to the research of food security in relation to psnp in rural households of the korahey zone, the study thereby fills a gap in the existing understanding regarding psnp. additionally, it might assist other academics who want to look into the psnp issue more deeply. additionally, the study's methodological importance helped other researchers by imparting knowledge and learning lessons to better understand the difficulties, achievements, and improved living standards of rpsnp. the study served as a starting point for future investigations into the psnp problem. empirical literature results of a find out about carried out via of abdusalem (2017) we learned that household size, schooling level, increased seed use, and distance to the nearest market have been drastically positively associated with a rural household's likelihood of participating in a productive safety net program. it shows that you made an impact. there were significant negative effects on participation in productive safety net programs according to abdukarim (2015), family size, active workforce, access to credit, off/off farm income, farm income, and household education level significantly influence participation in productive food security programs. in the same study by tadelee (2011) family safety nets in productive programs have been linked to the gender of the family head, the educational level of family members, meal protection issues, and the frequency of contact with improved employees. additionally, a high-quality affiliation was confirmed between big household measurement and participation in the psnp, suggesting that small family measurement was once related to larger meal demand compared with smaller households excessive and may additionally be related to a greater possibility of meal insecurity. according to ayalneh and wubshet (2012) livestock ownership correlates positively with well-being but negatively with program participation, whereas having the ability to use credit services correlates positively with program participation. the study undertaken by yibrah (2010) discovered that as a household's age increased, so did the likelihood of participating in a productive safety net program, which had a negative effect on participation. the find out by aman (2014) holdings, cultivated land, and distance from markets significantly affect participation in productive safety net programs. participation in the psnp was positively and significantly affected by variable distances from the market, whereas participation was negatively and significantly affected by access to credit services, extension contacts, the number of oxen, livestock holdings, and cultivated land. similarly, the study by anwar (2015) indicated that family head educational level, household size, livestock holding, extension remoteness, and market distance were significantly associated with participation in productive safety net programs. also, the study undertaken by mesfin (2018) indicated that the educational level of households global sustainability research global scientific research 24 conceptual framework it is clear that several factors may help to explain the determinants of household food security and the rural productive safety net program (rpsnp). based on the objective of the study, the independent variables selected to achieve the ultimate objective of the study are broadly categorized into socioeconomic, institutional, and demographic factors the relationship between two variables in this study. figure 1: conceptual frame work of food security and upsnp source: own design based on literature review method of research. in this chapter, the research methodology for the study is described, along with a description of the research field, data sources and types, target population, sampling techniques, sample size, data collection methods, data analysis techniques, and justifications for their use. study area the korahey zone contains the study area. the distances between the city and addis ababa, the capital of ethiopia, and jigjiga, the regional capital of somalia, respectively, are approximately 405 km and 1015 km. the korahey zone had a total population of 312,713 people as of the 2007 central statistics agency (csa) census, 177,919 of whom were men and 134,794 of whom were women. the majority of these people belonged to pastoral societies. i'm right here. this region's latitude and longitude are 6° 44' n, 44° 16' e / 6.733° n, 44.267° e, and its elevation is 493 meters above sea level. kabri dahar governorate has a total population of 136,142, of which 77,685 are men and 58,457 are women, according to the central bureau of statistics for 2007. the remaining 50,361 people (6 .99 percent) are pastoralists, while 29,241 people (21. 48 percent) live in cities. research design for this study, the researchers used descriptive and explanatory research designs. the research design refers to the processes and methods used to gather and analyze the necessary data. the goals a researcher wants to accomplish or the research questions they want to address will determine the study strategy they use (croswell, 2007). according to (kothar, 2004), claims that surveys and diverse types of fact-finding enquiries are included in descriptive research. socio

respondents in the first phase. the kebridehar region was deliberately chosen because of its widespread application of productive social protection programs. with 11 in the second-stage rural kebeles, five kebeles were randomly chosen as participants and nonparticipants in a productive social protection program. in the third step, sample 1 obtained from kebele's office is divided into two groups, and proportions are used. n = z2pqn e2(n−1)+z2pq n = (1.96)20.5 ∗0.5 ∗4577 (0.05)2(4577 −1)+(1.96)2∗0.5∗0.5 =354 the survey was carried out with the help of development agents (das) in each of the target. where: n = sample size; n = total population (1,925); z = 95% confidence interval under the normal curve (1.96); e = acceptable error term (0.05); and p and q are estimates of the proportion of the population to be sampled (p = 0.5 and p + q = 1). sources and types of data to obtain the necessary information for this study, both quantitative and qualitative data were collected from primary and secondary data sources. demographic, socio-economic, market and institutional-related variables relevant to the study were collected based on the nature of the information needed on various aspects of this study, employing a mixed method of data collection methods to generate adequate and reliable data from the respondents. in addition, data on the type of food items consumed by households in the last seven days were also collected. data analysis techniques the methods of data analysis used in this study were both quantitative and qualitative. to analyze the data, descriptive and econometric methods were employed. using frequencies, percentages, means, and standard deviations, descriptive statistical analysis techniques were used to discuss the results. to confirm the existence of statistically significant differences and systematic associations between the program and program participants on the hypothesized variables, chisquare tests and t-tests were used. frequency, percent, and chi-square tests were used to analyze different types of quantitative categorical data. the social science statistics package (spss) version 25, stata 13, and excel were used to analyze the data for this study. food security measurement models the household caloric acquisition approach: this model was used to measure household food security, which is measured by daily calorie intake, which is a continuous variable measured by kcal/ae/day at the household level. to measure the food security of households in the study area, information concerning the types and amounts of food items prepared for consumption by each household in the last seven days preceding the survey was collected. econometrics model specification binary logistic regression the binary logit model is defined as follows, according to gujarati, (1995): 𝑃𝑖=∈ (𝑌=1/x𝑖) = 1 1+e−(β0+β1xi) ………………………….………………… ………………….

of a productive safety net program on rural household food security. according to caliendo and kopeinig (2008), some steps apply in psm. these steps are predicting propensity global sustainability research global scientific research 26 scores, choosing matching algorithms, restricting common support areas, testing the matching quality or balancing tests, and performing sensitivity analysis. these are described as follows: step 1: propensity scores: a logistic model is used to estimate propensity scores for each observation. the advantage of this model is that the probabilities are bounded between zero and one. the dependent variable is dichotomous, taking two values: 1 if an individual participated in a productive safety net, and 0 otherwise. the covariates used to predict treatment assignment using logistic regression are specified as follows: li = ln ( pi 1 − pi ) = ln (eβ° + ∑ βjxji n j=1 ) = zi = β° + ∑ βjxji n j=1 where li is a log of the odds ratio in favor of participating in productive safety net program? zi = participant β° = intercept βj = regression coefficient to be estimated discussion and conclusions descriptive statistics study findings age of household heads: the mean age of the entire sample of all interviewed household heads was 48.03 years, with a standard deviation of 12.08. as a result, she had an average age difference of 1.48 years between households that were enrolled in the program, which had an average age of 48.80 years, and households that were not enrolled, which had an average age of 47.32 years. the average age of the sample household is 86, while the median age is 21, and vice versa. education: the highest grade was ninth grade, with the lowest grade being the 0th. the average educational background of all household heads in the survey area was 1.74. thus, with a mean difference of 0.32 years, the average number of school years for households in the program versus those who did not participate was 1.58 for the former and 1.885 for the latter. between households with and without program participants, they discovered that there was no statistically significant difference in the level of education. family size: there were 5.1706 people living in each household on average in our sample of respondents. when respondents were split into households with and without program participants, the average family size was 5.575 and 4.798, respectively. according to the statistical analysis, there was a statistically significant difference at the level of 5% (chi2 = -0.426 and p = 0.0061).livestock: the average number of livestock owned by participating and non-participating households in the sample surveyed was 2.979 at tlu. according to the survey's findings, livestock had a mean difference in tlu of 0.062 and 3.01 tlu for program participants' households and 2.948 for non-participating households, respectively. the results of a t-test (t = -0.426 and p = 0.000) also indicated that this difference was not statistically significant. extension contacts: across all households in the study area, there were, on average, 2,455 extension contacts. there were, on average, 2.13 and 2.74 contacts between households participating in the program and households not participating, with a mean difference of 0.04. the difference was also statistically significant with a probability of 5%, according to a t-test (t=4.7603 and p=0.0000). according to statistical findings of the typical distance across the sample of respondents from the market center, the market distance (km) between participating and non-participating households for a sample of respondents is 15.82 km. the findings revealed that program participants were spaced apart on non-participants was 10.51 km and 20.71 km,

households program, the binary logit model was estimated to determine the primary factors influencing household decision-making. the dependent variable in the psnp is a dummy that represents the household program and has a value of 1 for participant household programs and 0 for non-participant household programs. the specified binary logit model's explanatory power is adequate because the model's overall validity has been established and it is statistically significant at a p-value of 000. the pseudo-r-square was found to be around 0.1898, indicating that all explanatory significant variables included in the model explained 18.98 percent of the probability of household program participant households. the logit model's overall significance can also be inferred from the lr chi2

significantly related to households participating in the program, while the remaining five have a minimal impact and are more useful in describing the variation of households participating in the dependency program in the study area. at a 5 percent significance level, these are the respondent's age, family size, household age, gender, and distance to the market. other factors like household education, market information access, credit service availability, and off-farm/non-farm activities did not differ significantly between program participants and non-participants (above table). age of the household head: the results of the binary logit model indicate that, at a 5% level of significance, the household head's age positively and significantly affects the likelihood of households participating in the psnp program. when compared to younger people, household heads are more likely to participate in the program as they get older. the outcomes agree with mohammed (2017). family size: the results of the binary logit model indicate that, at the 5% level of significance in the study area, the age of the household head has a positive and significant impact on the household probability. statistical analysis reveals that, in terms of household size, there is a statistically significant difference between participants and non-participants. similar to this, focus group discussions reveal that households participating in the psnp have more family members than nonparticipating households according to mohammed (2017) and mesfin (2018). extension contact: the results of the binary logit model indicate that, at the 5% level of regional significance, the age of the household head significantly and positively influences the likelihood of households participating in the psnp program. when compared to younger people, household heads are more likely to participate in the program as they get older according to ((mohamed, 2017). propensity scores matching model on psnp's effect on rural household food security calculating the propensity score using the propensity score matching technique, the impact of a production safety net program on rural households' diets was evaluated. psm deployment consists of five steps. these include calculating p-scores, selecting a matching method, ascertaining overall support, calculating fit quality and effect, and carrying out a sensitivity analysis. using the logit model, propensity scores (ps scores) for participating and nonparticipating households were calculated. this stage gathers all the information on the independent variables that were generated using propensity score matching, which was used to perform the match on a single variable. global sustainability research global scientific research 28 a very low r2 value of 0.189, as seen in the table below, signifies that there aren't many differences between the typical characteristics of the sample's households. as a result, it might not be difficult to find a good match between effective safety net participants and nonparticipants. the results of the point estimates show that the household head's gender, household age, family size, extension contacts, service credit, and marketing strategy have a significant impact on the production safety net program. negative and insignificant (-187.33573) is the predicted logit intercept according to (caliendo and kopeinig, 2005). imposing common support region between participant and non-participant based on the likelihood of participation, estimates of psnp participation and propensity scores for all participating and nonparticipating households are created. the general support condition is the next stage in the propensity score matching technique after generating propensity score values for participants and nonparticipants using logit models. as the primary criterion for determining the area of common support between the two groups, eliminate any observations with a propensity score that is higher than the non-maximum participant's and lower than the participant's minimum propensity score (calindo and kopeinig, 2008). in order to determine the general area of support where the distribution of propensity scores for the treatment and comparison groups overlap, this is necessary (shahidur et al., 2010). potential scores are estimated for participating or treated households and the corresponding non-participating (control) household. the estimated propensity scores range from 0.0087 to 0.9118, with a mean of 0.6040 for participants and 0.3691 for those who have not been treated. table 3. shows the estimated propensity score distribution group observatio n mea n std min max all rural househol ds 334 .481 6 .236 6 .0087 .9669 participan t 160 .604 0 .205 5 .0586 .9669

were used as the samples for matching, as previously mentioned in the table above. both psnp and non-psnp households' propensity score values fall within common support categories. this method's fundamental criterion is the elimination of all observations with trend values in the opposite group that are below the minimum and above the maximum.(kopeinig, 2005) figure 2. density distributions of propensity scores using nnm n (4) 0 .2 .4 .6 .8 1 propensity score untreated: off support untreated: on support treated: on support treated: off support global sustainability research global scientific research 29 looking for common support it was discovered that 316 observations (147 from untreated participants and 158 from treated participants) were within common support, while 18 observations (13 from untreated participants and 5 from treated participants) were outside the purview of common support and regional analysis. but 316 observations— 161 from untreated (non-participants) and 155 from treated (participants)—were within common support and were included in the analysis. these few observations served as the foundation for an analysis of the psnp program's effects on household food security in the district. table 4. support for psmatch2 psmatch2 treatment assignment common support off support on support total untreated (non participant) 13 161

family units. the best outcomes for a good estimator depend on a number of factors, including testing for equality of means (also known as pseudo-r2) and examining the size of paired samples. the ideal estimator is one that is fitted, controls for all explanatory variables, has a small mean difference between groups, a low pseudo r2 value, and a large fitted sample size. the conformance quality test estimates are based on the following performance standards: the results show that 5-neighbor agreement with 0.1 bandwidth is the best estimator of the available data. psm and covariance balance before and after matching are statistically tested . the average standardized bias before and after matching, or the overall bias reduction made possible by the matching procedure, are shown in the table below. for prematched covariates, standardized differences had an absolute value ranging from -0.8% to 115.8%. following matching, the residual standardized differences of covariates for all covariates fell below the 20 percent critical value suggested by rosenbaum and rubin (1985) and ranged from 1 point 2 to 16 point 7 percent. table 5. balancing tests of the covariates (pseudo r2,

matching procedure generates a highly covariate balance between the treated and control samples that is prepared for use in the estimation procedure. similar to this, the t-test showed that all covariates were non-significant after adjustment, whereas 8 of them were significant before adjustment. this demonstrates that the standardized mean difference of all covariates used to calculate propensity scores, which was 35 point 3 percent before adjustment, is now only about 10 point 6 percent. furthermore, the likelihood ratio tests' p-values show that the joint significance of the covariates was always rejected after adjustment but not before. low pseudo r2, low standardized bias, significantly reduced overall bias, and no significant p-values in the adjusted likelihood ratio test suggest that trends between the treatment and control groups have been successfully identified. 4.3.6. the average treatment effects (att) are estimated. the impact of production safety net programs on rural households' access to food is demonstrated in this section. as a result, the mean therapeutic effect (att) of psm was calculated with a neighbor of 0.5. the corresponding results only provide proof that production safety net programs have a statistically significant effect on rural households' access to food. thus, the program participant's 214.5 kcal/ea/household-day increases her psm model results in table 6 below, showing that households taking part in the production safety net program have a true average wage guarantee means that having a household's food security affected in any way by participation in production safety net programs. this suggests that under the same covariates, the production safety net program has an impact on food security of 214.5 kcal/au. the fact that households choose to take global sustainability research global scientific research 30 part in the program seems to make them relatively safer and less prone to food insecurity than households who do not is encouraging for att. table 6. impact of program participant households psnp on household resilience to food security sensitivity analysis it is becoming more and more important for researchers to test how robust their findings are to changes in certain presumptions. sensitivity analysis can be used to address this problem because non-experimental data cannot be used to estimate the level of selection bias. to test the putative att's sensitivity to departures from the cia, rosenbaum (2002) suggests employing the rosenbaum boundary approach. table 7. rosenbaum

access to food, four rural areas in the kabri dahar district of the somali regional state of korahey were randomly selected out of a total of 11 rural areas. after thorough research, design was used. a multi-stage sampling method was used to collect data from the 334 household heads that were sampled. results from descriptive statistics reveal a statistically significant difference in household characteristics, such as age, gender, family size, distance from the closest market, and extended contact, between program participants and non-participants. however, there were no appreciable differences between participants and nonparticipants in terms of other factors like household education, market information access, financial services access, and off-farm activity. aside from age, family size, and distance to the closest market, the logit model's findings also revealed contact information for extension. was significantly and negatively affected by psnp participation, whereas household education status, access to market information, access to credit services, and offfarm activity were not significantly different between program participants and non-participants. the findings show that a total of 194 (58.80%) of the sampled households were found to be food secure, providing the minimum daily calorie recommendation, while 140 (41.92%) were food insecure, not meeting the minimum daily calorie requirement. this was established by using a cut point of a minimum of 2200 kcal/ae/day. variable sample treated controls difference s. e t-stat kcal unmatched

study area's household food security was improved by the productive safety net program. compared to nonparticipating households, rural households that took part in the program consumed 214.5 kcal/ae/day more food on average. in comparison to non-participants, program participants were older, had larger households, and lived farther away from local shops and extended networks. participating families were more likely to match their age, gender, family size, and distance from the closest marketplace and extension contact person. in order to address the issue of food scarcity, the study site's psnp program is essential. the production safety net program has had a significant positive impact on participants' food security in the study area. these studies support the idea that psnps significantly improve household food security. recommendations the following recommendations are provided in consideration of the study's findings mentioned above: ➢ household length becoming substantially longer has an effect on family participation in psnp. a family with a large age range, a large circle of relatives, a long distance from the nearest marketplace, and extended touch may be eligible to participate in an application. as a result, it is far from optional to take into account personal family planning in any improvement interventions carried out by authorities and non-governmental organizations that may manipulate rapid population growth to provide solutions to the family meals security problem. ➢ finally, given the sure diploma of versions of application effect studies, if similarly conducted studies with extra scope and in a one-of-a-kind region examined the effect of psnp and different meal protection applications on meal protection, it would be better. future researches the study included a limited number of households and did not include all important factors and other aspects of food security. it focuses on how the producer safety net program affects household food consumption and examines the variables that affect psnp program participation. accurate data on food consumption in the research area can be difficult to collect because rural households frequently struggle to recall all of their consumption details. it's possible that some participants and non-participants will be unwilling to provide an honest response to inquiries about their animals. this limitation may arise due to a lack of information and awareness in the rural household study areas. regardless of these limitations, it is anticipated that the study will create valuable information that may not be advantageous to various stakeholders interested in the field. acknowledgments: the kebri dehar university provided financial and logistical support, for

abstract working group ii of the ipcc sixth assessment report focuses on climate change impacts, adaptation, and vulnerability in the context of sustainable development. this ipcc evaluates climate model simulations from cmip5 and cmip6 of the world climate research programme. depending on global warming levels after 2040, climate change will threaten natural and human systems. midand long-term consequences are several times higher for 127 identified major hazards. climate change is having increasingly dire, interconnected, and often irreversible effects on ecosystems, biodiversity, and human systems, and risk provides a framework for comprehending these effects and for devising strategies to prevent unfavourable outcomes for present and future generations. as climate change implications and actions are enacted, more is known about how they affect justice and socioeconomic advancement. ar6 emphasises change and quick climate action to achieve such goals. keywords: climate change; ipcc; risk; disaster; adaptation introduction in the last two decades of the twenty-first century, life expectancy, per capita income, and education have experienced unparalleled growth. however, the scale and intensity of human activity have also increased, leading to more negative environmental impacts. in this framework, the purposeful and unintentional human effects on the background cause the most urgent environmental issues, which are genuinely global: decreasing forests, expanding deserts, eroding soils, deteriorating rangelands, rising carbon dioxide levels, dropping water tables, rising temperature, more destructive storms, melting glaciers, rising sea level, increasing floods and forest fires. timely examples include global climate change, which reduces humanmanaged natural resources (such as biodiversity, landscapes, and wildness), natural resource productivity (such as agriculture), damage to the built environment (such as flash floods from cloud burst has risen), and dangers to humans due to extreme weather changes. intergovernmental panel on climate change (ipcc 2022) is, therefore, the only event of its kind that focuses specifically on in-pit crushing and conveying on a global scale. the sixth episode of a conference series has been a significant success. when it comes to quantifying the global impact of climate change, no other organisation compares to the intergovernmental panel on climate change (ipcc) (rama et al., 2022). they are crucial sources of scientific data and technical advice for the unfccc, kyoto protocol, and paris agreement. after a successful event in chile in 2018 (birkmann, j et al., 2022), this meeting will continue the tradition of offering a forum for high-level networking and conversations on ipcc in all its forms. impacts, adaptability, and susceptibility to climate change were the focal points of ipcc's 2022 report. by maximising synergies and minimising duplication, integrating adaptation and mitigation with the sdgs can boost the effectiveness of both. literature, research, practice, and decision-making related to climate change have all elevated the importance of the notions of risk and risk management (caretta et al., 2022). the ar6 report addresses adaptation options and their efficacy and adequacy in achieving societal goals related to climate change, such as decreasing vulnerability and boosting resilience. three aspects of climate justice are highlighted in ar6: distributive justice, procedural justice, and acknowledgement (shaw, r et al., 2022). this study examines how ipcc working group ii assessment report 6 (ar6), with three subsequent special reports, might help mitigate climate change and flood disasters. because of their role in regulating temperature and natural hazards. a changing climate in a changing world since the ipcc fifth assessment report (ar5) publication in 2014, many significant climate-related developments have occurred worldwide. that report indicated many simultaneous changes in the physical climate system, including higher average world temperatures, lower ice volumes, higher sea levels, and different global precipitation patterns. globally, both global sustainability research 39 global scientific research natural and human ecosystems have been affected by changes in the physical climate system, particularly more intense extreme events. water and food security were affected; infrastructure was damaged to a larger extent; more deaths and illnesses were documented; people were uprooted or relocated; their livelihoods were ruined; mental health issues were increased; and inequalities widened. additionally, since ar5, a growing number of individuals around the world have learned about climate change, found it to be a severe issue, and believe it to be an emergency that needs rapid attention (new, m et al., 2022). compared to 2013, when just half of respondents in 23 countries saw climate change as a pressing issue, in 2017 nearly two-thirds of respondents from 50 countries—representing over half of the world's population—held this view (fagan, m et al., 2019). since ar5, there has been a substantial rise in planning and initiatives to mitigate the current and future risks associated with climate change. concerns about climate change have prompted actions from governments, businesses, and individuals (o’neill, b et al., 2022). however, as the report details, current climate policies and efforts are insufficient on their own to meet these goals. the world is in the midst of some of the most profound cultural and environmental upheavals in decades when people take action on climate change (parmesan, c et al., 2022). rising inequities along gender, wealth, age, race, and ethnicity, as well as a rapidly urbanising world population, are all examples of gendered issues. while economic disparities between countries have narrowed globally, they are increasing domestically (bongaarts, j, 2020). observed changes to hazards and extreme events “climatic impact drivers” (cids) are what working group i of ar6 refers to when discussing the causes of negative, positive, or neutral changes in the physical climate systems. hazards, on the other hand, are frequently the subject of discussion in natural systems literature physical occurrences with the potential to have a detrimental impact on ecosystems and environmental resources can be classified as hazards, and these hazards can be either natural or manmade in origin(allan, r et al., 2021). extreme weather events and other natural disasters can happen rapidly, but the cumulative effects of various climate risks might take decades or longer to manifest in the form of soil degradation and erosion. risks to protected areas are evaluated based on observations of exposure. the frequency and severity of disasters like floods, droughts, cyclones, heat waves, and fires have increased as a result of climate change and other disturbance regime alterations. to better represent both small-scale processes and exceptional occurrences, climate models with increased resolution would be very useful. these disruptions have a significant negative effect on ecosystem functioning, biodiversity, and ecosystem services, but are rarely taken into consideration in impact models. many ecosystems rely on the regular occurrence of extreme events, and many species have adapted to the longand short-term climate swings within the disturbance regime they have experienced (cissé, g et al., 2022). extreme episodic occurrences can alter or disrupt ecosystems’ functionality, which is essential for such adaptive strategies. while we have a good handle on the primary climatic hazards on a global scale, we know far less about the impact of many disasters on ecosystems at once, making it difficult to quantify the results in future forecasts. even if individual occurrences are not particularly severe, the combination of several can have a devastating effect (sharrief, a et al., 2019). examples include sea level rise, exceptional coastal high tides, storm surges, and river flows can all have a multiplicative influence on flood risk and freshwater system consequences. the extensive dieback of some forests (for example, in australian eucalypt forests) may be caused by a combination of causes, including changes in rainfall and heat, altered plant growth and nutrient allocation under elevated co2, and the rates of herbivores and insect outbreaks. risk assessments usually consider a single climatic hazard with constant variability (zscheischler, j et al., 2018). ecosystems and disaster risk reduction reduced disaster risk is a stated goal of several environmental policies and strategies under the hyogo framework for action (hfa), which includes land use, natural resource management, and adaptation to climate change. a key component of the hfa's approach to increasing the robustness of societies and states is the management of ecosystems. the 2011 global assessment report on disaster risk reduction stresses the importance of integrating ecosystem-based approaches into disaster management (schipper, e et al., 2022). disaster risk and the effects of climate change can be mitigated, thanks in large part to the regulatory and provisioning functions supplied by ecosystems. the ability of ecosystems to reduce risks has numerous positive effects on human security. numerous studies have demonstrated the crucial role ecosystems play in mitigating dangers. various names are used to describe ecosystems in the disaster literature. some examples include: natural buffers, natural barriers, natural infrastructures, green and blue infrastructures, bio shields, and protective greenbelts. therefore, they protect individuals from the worst of what nature can throw at them. example: studies done after the 2004 indian ocean tsunami demonstrate the value of coastal forests and plants (such as mangroves) in protecting lives, property, and resources from the devastation of tsunamis(o’neill et al., 2022). water security in climate change and climate resilient development for a population to be considered water secure, they must be able to guarantee that they will always have global sustainability research 40 global scientific research access to sufficient supplies of high-quality water in an environment free from violence and political unrest. this water must be used to maintain livelihoods, human health and social progress, as well as to safeguard against water pollution and natural disasters. water insecurity risks are a global issue. water crises have been one of the top five threats in the world economic forum’s global risks report since 2015. water is a crucial component in the necessary system transitions for climate-resilient development, and it is given significant attention in the sdgs. a majority of the sdgs will not be achieved unless everyone has access to clean water. without effective adaptation, future water-related climate change impacts on many economic sectors are estimated to reduce global gdp by mid-century, with higher projected losses in lowand middle-income nations (pörtner, h et al., 2022). second, freshwater availability across places and time is directly impacted by climate change, which also impacts water demands for various applications like irrigation and may exacerbate pre-existing social difficulties. vulnerability to water-related consequences of climate change and extreme weather is now felt in all key sectors and is predicted to grow in the future, including agriculture, energy, industry, and water for health and sanitation. agriculture and irrigation comprise 60–70% of all water withdrawals. lack of clean water and sanitation causes several water-borne diseases. in 2017, 2.2 billion people needed adequate drinking water, and 4.2 billion lacked safe sanitation. the present covid-19 outbreak is exacerbating water inequities. droughts and other extreme occurrences have damaged hydropower and thermal power production globally. between 1971 and 2000, 16% to 39% of cities faced surface-water shortages. more than 440.5 million city dwellers would experience water scarcity by the year 2050 (dodman, d et al., 2022). in south america, not many people have access to clean drinking water. if global warming is limited to 1.5 degrees celsius, risks to water-intensive businesses can be reduced and flexibility can be maintained. the future of water security is in jeopardy due to the proliferation of mitigating strategies. afforestation and reforestation can have major effects on water supplies, but only if they are carried out correctly. the risks associated with climate change on water security can be mitigated by considering the direct and indirect effects of mitigation efforts on water resources(shaw, r et al., 2022). climate change impacts are stressing agriculture, forestry, fisheries, and aquaculture short-term food shortages and price increases caused by weather extremes related to climate change exacerbate already severe food insecurity in some parts of the world. as a result of changes in agricultural output, food prices, and household incomes, the number of people who go hungry will rise as a result of climate change. extreme climate occurrences will increase, forcing particular food-producing locations beyond safe climatic space. one study predicted that in sub-saharan africa and southeast asia, heat stress from projected three °c warming over baseline (1986-2005) will lower labour capacity by 30-50%, contributing to a 5% increase in crop prices due to greater labour costs and production losses, so affecting food supply, access, and livelihoods (morecroft, m et al., 2022). they are anticipated that by 2100, climate change might harm agricultural and marine fisheries in 90% of the world’s countries. globally, shellfish aquaculture habitat suitability will drop after 2060, but sooner in several asian countries (cooley, s et al., 2022). climate change will raise food costs and management issues. pathogens, hab, and toxic inorganic bioaccumulation pose safety issues. micronutrient insufficiency is widespread and will be a concern throughout the first half of the century, with serious health consequences. damage to pollinator populations, soil biodiversity, and water infrastructure, thereby reducing agricultural employment and threatening human health are additional dangers to food safety and nutritional balance posed by climate mitigation plans, that ignore the possibility for increased rivalry between food production and other uses for scarce land and water(new, m. et al., 2022). policy the ipcc wgii ar6 builds on the ar5, three special reports, and the simultaneous wgi and wgiii ar6 assessments. the findings and assessment methodologies employed across these reports influence the wgii ar6 starting point. they include the strong acknowledgement of the need for climate action, the increased attention to risk, and the effort to combine near-term climate solutions with longer-term changes. the conference’s consensus was that human activity had a noticeable impact on the global climate. climate change has affected human and ecological systems. unchecked greenhouse gas emissions increase the risk of severe, pervasive, and irreversible impacts on people and ecosystems due to increased warmth and longer-lasting changes in all elements of the climate system. a substantial cut in emissions over the next few decades can lessen 21st century climate risks, increase opportunities for effective adaptation, lessen mitigation costs and impediments, and help pave the way for climate-resilient pathways to sustainable development. policies, partnerships, and integrated measures that connect adaptation and mitigation with other societal goals are essential for successful implementation. at the time of the ipcc ar5, there was little scientific research on 1.5°c global warmings. in 2018, the ipcc released a special report on the implications of global warming of 1.5°c and corresponding global ghg emission scenarios. the analysis compared global warming at 1.5°c and two °c over pre-industrial levels(schoeman et al., 2022). it discussed solutions to achieve the paris agreement’s aims. quoted report findings: global sustainability research 41 global scientific research if warming continues at the current rate, 1.5°c might be reached by 2052. • global warming of 1.5°c increases climate-related dangers for natural and human systems compared to 2°c. 1.5°c warming will require less adaption than 2°c. models show that if global warming stays below 1.5°c, global net anthropogenic co2 emissions will fall to zero by 2050 from their 2010 levels (interquartile range: 40% to 60%). interquartile range (iqr): 2045–2055. • even with extremely ambitious improvements in emissions reductions beyond 2030, national mitigation efforts as represented by the paris agreement would not be sufficient to keep global warming below 1.5°c. nature-based solutions not only help with adaptation and mitigation of climate change, but also with the achievement of other sustainable development goals. nature-based climate change mitigation relies on the creation of climate-resilient systems that serve various sustainable development goals, which in turn requires participatory decision-making and adaptive management. a move to more deliberate decisionmaking is required to keep management on track as the effects of climate change reverberate across infrastructure. poorly managed, nature-based mitigation strategies could have negative effects on human health, reduce the amount of usable land and water, and compromise long-term sustainability. restoring natural ecosystems and natural processes that have been damaged or destroyed is an important adaptation and mitigation strategy. landscape, marine, and biological community species composition are all at risk from the effects of climate change, and restoration efforts must account for this. when an ecosystem is nearing its tipping point, as is the case with tropical coral reefs, climate change may overwhelm efforts to restore or maintain the environment. carbon is stored and many species are supported by thriving forest ecosystems that are lost in degraded areas. in low, boreal, and temperate biome regions, natural forest ecosystems survive but are managed, degraded, or removed in many parts. deforestation and land degradation continue to emit ghgs. protecting natural forests and managing seminatural forests sustainably are successful. urban climate adaptability can be aided by solutions rooted in nature. all of these elements have positive effects on human health and well-being: urban forests and green spaces (parks and green roofs) can provide cooling effects; coastal wetlands and mangroves can minimise storm surges and floods; sustainable drainage systems can prevent surface flooding due to extreme rainfall. water shortage is a mismatch between freshwater demand and physical availability. socioeconomic and governance inequalities generate water scarcity and insecurity. climate change-caused water shortages require greater water management. climate change, agricultural practises, water demand, and governance will influence future water security. not simply climate change threatens water security. climate change may affect water supply, water quality, and flooding in many locations, jeopardising water security. alternative result probabilities rely on regional climate shifts and socioeconomic futures. future water scarcity predictions complicate water security and adaptation methods due to climate change. global warming can reduce water security challenges. at these temperatures, regional climate shifts are clearer. half of the world population is vulnerable to severe water scarcity for at least part of the year due to climatic and non-climatic variables, which is anticipated to worsen with increased warming. high population densities and insufficient water supply, accessibility, quality, and governance cause water insecurity worldwide, especially in south asia, north china, africa, and the middle east. high-water-availability areas can be water-insecure due to flooding, low water quality, and inadequate governance. future water security depends on socioeconomic, management, and climate change. climate change can diminish water supply and increase flooding, contributing to water insecurity. future socioeconomic conditions are a crucial driver of water insecurity, requiring adaptation to climate change. in many locations, policy problems are considerable due to climate uncertainty. adaptation solutions in crop production range from the field and farm-level technical alternatives like crop management and cultivar/crop options to income diversification and index-based insurance. land use planning helps locate settlements and infrastructure. the built environment and its impact on natural systems are both impacted by climate change, which in turn drives growth in high-risk locations. despite this, cities in varied situations have restricted climate adaptation zoning and land use regulations. traditional zoning regulations (those that permit only one use in a given area) and land use planning can be used to mitigate threats by encouraging people to move away from dangerous areas or hide from them. zones for protective urban infrastructure (such seawalls, levees, dykes, and slope revetments) and avoidance measures that restrict or slow urban expansion are all part of a comprehensive plan for protection (e.g., growth containment and no-build zones). research from both the global north and south shows that conventional zoning is not as effective as land use policies for climate adaptation that prevent negative human-nature interactions and that curb spatial inequity, both of which can cause climate gentrification and increase the vulnerability of economically disadvantaged groups to climate-related risk. considerable variation exists between nations and regions, making it unlikely that current global efforts in health adaptation would be sufficient to safeguard the health of populations and communities from most climate-sensitive problems. although health is a priority sector in 54% of ndcs, less than 1% of international climate financing goes toward adaptation to climate change in health. when planning for and responding to climate change’s potential health impacts, it’s essential to consider the global sustainability research 42 global scientific research wide range of interconnected factors that can impact the health of populations and the efficiency of health care delivery systems. given the complexity of the interconnected environmental, social, and health systems that are impacted by climate change, a systems-based approach can facilitate the identification, implementation, and evaluation of solutions that support population health and health systems in the short and long term. this approach provides insight into how to enhance health and wellbeing in a variety of contexts. in order to mitigate the risks to human health caused by climate change, it is essential to implement effective governance structures, arrangements, resources, and mandates for adaptation. health adaptation might be less successful or destructive if it becomes compartmentalised without integration and collaboration across sectors. integration and collaboration include working across national ministries and agencies, as well as between federal and municipal governments and the commercial sector, academia, ngos, and civil society. in addition to top-down approaches to policy development and implementation, bottom-up efforts, in which community actors are involved in programme design and draw on their local practises, perspectives, ideas, and experiences, are also useful. there is a chance to improve public health by incorporating it into discussions and decisions about climate change and by bolstering public health partnerships and collaborations. cross-sector cooperation can be facilitated by building networks, integrating organisations, and developing policies. results and conclusion working group authors follow ipcc recommendations on expert judgement. the ipcc sixth assessment report (ar6) has advanced interdisciplinary climate change assessment from ar5. as a result, assessment findings spanning the entire gamut of climate science, consequences, risks, and policies are more directly comparable. the risks, consequences, vulnerability, societal adaptation, mitigation, and sustainable development associated with climate change have all been better understood because to the utilisation of a plethora of newly available sources of knowledge. climate change adaptation is successful if reasonable efforts reduce risk and vulnerability and achieve their aims. goals of this nature are established and monitored globally following pre existing international frameworks and norms. achievable objectives for impact management at the local and national levels are conditional on the effects under consideration, the nature of the measures being taken, and the scale at which they are being implemented. for a comprehensive evaluation of the impact of an act, it is essential to consider how well the adaptation serves its intended purpose, how well it works, and how well it fits with the principles of justice. six reports have been released by the ipcc documenting climate and ecological changes brought about by humans. there is no hiding from these shifts; they are happening now and will only accelerate in the years and decades to come. as part of its ar6 report, the ipcc also highlights the efforts people are doing to adapt to climate change. even positive adaptation might have negative effects on existing structures. when other acts are performed, the underlying structure of the system is altered. example: constructing a seawall to defend a coastal neighbourhood from flooding. changing land use restrictions and implementing a managed retreat programme may be a transformational adaptation. a seemingly insignificant factor, climate risk in mortgages and insurance is actually quite gamechanging. because the amount of greenhouse gas (ghg) mitigation influences the amount of transformational adaptation required to prevent intolerable dangers, some transformations may be inevitable. rapid adjustments in energy, land, urban, and industrial systems are needed to get on a low-emissions path that is in line with paris agreement goals. dangers must be mitigated even on low-concentration paths, and transformational adaptation is essential for this. in order to mitigate (but not eliminate) intolerable dangers along higher concentration trajectories, superior transformative adaptation is required. if a transformation isn't well thought out, it may be necessary to make alterations along the way. water scarcity and insecurity are caused by socioeconomic and governance disparities. better water management is needed to adapt to climate-caused water shortages. future water security will depend on climate change, agricultural practises, water demand, and governance. water security is endangered by more than climate change. climate change may threaten water security in many countries by affecting water supply, quality, and flooding. regional climatic alterations and socioeconomic futures are needed to evaluate potential outcomes. predictions of future water scarcity complicate climate change risks to water security and adaptation methods. water security challenges can be alleviated if global warming is limited. because at these temperatures, regional climate shifts are less obvious. climate change has monetary effects, some of which are precipitated by slow-onset and extreme weather events. the economies of those areas that use less energy and have a competitive edge in sectors like agriculture and tourism are doing well. short-term economic growth has been slowed by some extreme weather occurrences like tropical cyclones. more assets have been exposed to extreme climate hazards due to non-climatic characteristics such as settlement patterns and infrastructure sitting, leading to greater losses. individual lives have been disturbed due to changes in agricultural productivity, repercussions on health and food security, damage to homes and infrastructure, and loss of property and income, which in turn has affected gender and social equity. ar6 emphasises social justice and knowledge. as climate change consequences and actions are implemented, more is known about how they affect global sustainability research 43 global scientific research justice and socioeconomic progress. the ar6 emphasises transformation and swift climate action to satisfy societal goals. funding: regarding funding, there is

march, 2023 abstract global transmission of the 2019 coronavirus illness (covid-19), caused by the coronavirus 2 strain associated with severe acute respiratory syndrome, has started (sars-cov-2). the pandemic has had far-reaching, devastating effects on human society, the natural world, and the environment on a global scale. the many links in the food production chain, particularly agriculture and cattle, are also badly impacted in terms of product sustainability and monetary losses. there has been a considerable drop in meat, milk, and egg production because of the global epidemic. national and international movement limitations enacted as part of public health sector control efforts have impacted the accessibility of inputs for livestock producers and farm outputs, veterinary services, farmworkers, and animal care businesses. as covid-19 impacted the global livestock sector which is continuing, understanding and implementing sustainable approaches in livestock production is needed for both academia and industry. to respond to this need, this study carried out a systematic review of the existing literature on the impact of covid‑19 on the sustainability of livestock performance and welfare on a global scale. significant consequences on livestock performance sustainability, worldwide animal welfare, and mitigation methods are discussed in this paper in light of the recent outbreak of covid-19. keywords: livestock production; covid-19; supply chain; animal welfare; sustainability introduction worldwide anarchy in 2019 can be traced back to the pandemic coronavirus epidemic that began that year. the disease has had such a terrible effect on people's health, economies, and social life all across the world that the world health organization (who) has declared it a pandemic (zhou et al., 2020). a contributing element to the virus's virulence is the fact that covid-19 was initially identified in zoo specimens (tazerji et al., 2020). the virus destroyed all of the towns and ended life as it had been known before in a relatively short length of time. although lockdown was an essential measure to halt the pandemic's spread, it had devastating unintended consequences for human and animal health and caused a financial disaster on a scale never previously witnessed. the inability of the populace to leave their homes has these results (shehata et al., 2021). covid-19 has also had a significant negative impact on agricultural sectors worldwide (rahman et al., 2021). this has had an obvious effect on the long-term viability of animal production systems, especially those that produce meat and milk, as well as supply chains, trade, and consumers' purchasing patterns (bekuma, 2020). global food insecurity is a big issue, especially because of the pandemic's effect on cattle production systems. the situation has worsened as a result of organizational shifts in animal care. as covid-19 impacted the global livestock sector which is continuing, understanding and implementing sustainable approaches in livestock production is needed for both academia and industry. however, there is a research gap between covid-19's impact on livestock production and the sustainability of livestock performance. to fill up this research gap, this study carried out a systematic review of the existing literature on the impact of covid‑19 on the sustainability of livestock performance and welfare on a global scale. the key concerns of this study are the long-term viability of livestock production and the impact that covid-19 has had on the health and well-being of animals. this review accumulates information from various organizational reports, cited observations, and scientific papers in order to illustrate how the outbreak of covid19 has affected livestock production all over the world, including the dairy, beef, and poultry industries, as well as their respective management systems. this kind of information and data might be helpful in making substantial efforts to improve the current situation and to assert learning for our future, with a particular emphasis on food security through sustainable livestock global sustainability research global scientific research 2 production. moreover, this study highlights covid-19's effects on animal welfare and health which could be helpful to achieve sustainability of farming operations. furthermore, this article provides recommendations for improved animal husbandry during the covid-19 pandemic and the sustainability of livestock production. methodology to provide a complete understanding of the sustainability of livestock performance and welfare on a global scale, this study conducted a systematic literature review to summarize the results and discussions on studies that cover the impact of covid‑19 on the sustainability of livestock production. a systematic review of the scientific literature leads to the selection of 44 documents published between 2020 to 2022. the documents were collected from web of science (wos), scopus, and google scholar databases. figure 1 presents the development of criteria for document selection to conduct the review. this work presents an overview of the impact of covid‑19 on the sustainability of livestock performance and welfare on a global scale. to ensure the quality of the present study’s findings, the development of a relevant agenda for future research, and provide appropriate recommendations for sustainable livestock production, this study included the research articles only from peer-reviewed journals. these papers were further analyzed to assess if the focus of their study was related to the present study’s objective. figure 1. the development of criteria for document selection covid-19’s impact on livestock production economy, food distribution networks, and people's standard of living are only few of the many spheres of influence that are intricately linked to livestock production systems (fao, 2020a). the covid-19 pandemic has had a devastating effect on the whole animal-rearing industry, development of criteria for document selection literature available in web of science (wos), scopus and google scholar research articles on the impact of covid-19 and livestock production reports from the food and agriculture organization (fao) literature published in between 2020 to 2022 global sustainability research global scientific research 3 including its processing, transportation, sales, and consumer behavior (fao, 2020b). processing facility closures, travel restrictions, and quarantine/isolation practices all contributed to a scarcity of workers and/or the elimination of some jobs in the food supply chain. hence, many countries' agricultural systems are under danger (fao, 2020b). backlogs have developed in the majority of austria's animal production systems due to the labor issue. eighty percent of austria's meat processing industry workers are immigrants from eastern european countries (hashem et al., 2020). between 60%-70% of chinese dairy farms reported a lack of workers in february 2020. (qingbin et al., 2020). in addition to other essential imported feed and feed ingredients, such as soybeans, wheat, and corn, a number of countries have said that they do not possess this commodity (rahimi et al., 2022). developing countries have also suffered as a result of their reliance on international trade (galanakis, 2020; raihan, 2023a). due to trade and movement limitations, several countries experienced a lack of veterinary services, production tools, vaccines, disinfectants, feed additives, and medications on the farm level (fao, 2020b). the animals' health and well-being suffered as a result of this (hashem et al., 2021). the global market for animals and animal products has also suffered severe harm as a result of the closure of a large number of retailers and restaurants, the implementation of a stringent lockdown, and the restriction of transit options. twelve to fifteen percent less milk and cheese were consumed in the us (gibbens, 2020). sales of meat, eggs, and milk all dropped drastically in the united states, southeast asia, the middle east, and latin america during the covid-19 pandemic (galanakis, 2020). the lack of farmland has also contributed to an increase in the price of animal feed around the world (fao, 2021a). the impact of covid-19 on the long-term viability of cattle production systems is shown in figure 2. figure 2. covid-19 pandemic's effect on the sustainability of the livestock supply chain and the worldwide economy source: adapted from fao (2020b) global sustainability research global scientific research 4 covid-19’s impact on animal products this pandemic has generated significant secondary health concerns (for both humans and animals) and economic loss, despite the fact that social isolation and lockdown are necessary to limit and delay the spread of the virus (shehata et al., 2021). this article explores how factors like lockdowns, isolation, panic, and employee illness affect livestock productivity. meat some specialists speculated at the outset of the pandemic that sars-cov-2 could be spread from humans in china to pangolins (who, 2021). the rising global population has resulted in a higher demand for meat and other foods (raihan et al., 2021; raihan et al., 2022a; raihan and said, 2022; raihan, 2023b). the great bulk of the meat that is consumed by humans comes from livestock raised in intensive farming operations. the main components of worldwide animal production, imports, and meat exports are broken down into thousand tonnes of carcass weight equivalent and presented in table 1 for the years 2019 and 2020 (before and during the covid-19 pandemic). since the beginning of the pandemic in 2019, there has been a decline in bovine meat output as well as decreases in imports and exports, whereas pig meat has shown the opposite trend (fao, 2021b). in countries with a low income and a food deficit, production, imports, and exports of meat have all fallen. on the other hand, in developed countries, the output of meat has climbed while imports and exports of meat have decreased. in general, the findings indicate that the influence of covid-19 on the production, imports, and exports of meat differs according to the kind of meat, with poultry meat being unaffected in comparison to other types of animal meat. in addition, the stages of development that countries are now in have a direct bearing on how output, imports, and exports shift through time. table 1. the livestock production, imports, and exports of meat (measured in thousand tons of carcass weight equivalent) worldwide before and after the covid-19 pandemic meat classifications production imports exports 2019 2020 2019 2020 2019 2020 poultry 131,562 133,266 12,451 12,501 14,241 14,226 pigs 110,095 109,200 9,101 11,574 9,553 11,889 bovine 72,410 71,408 10,627 10,650 11,335 11,193 ovine 16,214 16,276 1,045 977 1,049 981 worldwide production of meat 337,209 337,182 33,630 35,999 36,611 38,694 low-income nations with food deficits 27,272 26,558 2,452 2,134 1,741 1,579 less developed nations 14,448 14,570 1,483 1,393 56 50 source: fao (2021b) although there are no statistics available about the effects of the covid-19 pandemic on the production of small ruminants, there has been claimed to be a short-term economic impact of covid-19 on the small ruminant flocks in spain. when compared to the pricing in march 2020, milk prices for dairy goat flocks experienced a decline of approximately 4.5 cents per liter in april 2020. on the other hand, the cost of one month's supply of sheep milk remained practically unchanged throughout this time period, with some sources indicating a rise of more than 6 cents per liter in comparison to the previous year. in addition, the worldwide data collected from 2,750 spanish flocks revealed a decrease in the price of lamb ranging from 16.8 to 26.9%. this information was obtained. in a similar fashion, the prices of goat kid meat fell by 12.5% per kilogram. (vidaurreta et al., 2020). eggs currently, there is no proof that eggs or other poultry products can transmit sars-cov-2 to humans (suárez garca et al., 2020). in contrast to the 2006 avian flu pandemic, which only affected a tiny portion of the chicken processing business, covid-19 has had far-reaching consequences for the whole industry (das and samanta, 2021). market closures and restrictions on egg sales were direct results of the covid-19 epidemic. because they couldn't sell their eggs to nearby supermarkets or eateries, farmers took a major financial hit (hafez et al., 2021). restrictions on farmer travel, disruptions in the food supply chain, and containment efforts conducted during the covid-19 pandemic led to a drop in the value of global egg imports and exports in 2020 compared to 2019. processed food eating ill animals or foods that have been contaminated by other foods, diseased food handlers, or contaminated food contact materials is one way that sars-cov-2 could potentially be disseminated. another way is by the consumption of foods that have been contaminated by other foods (oakenfull and wilson, 2020). the centers for global sustainability research global scientific research 5 disease control and prevention (cdc) have so far pinpointed processed foods, packaging, and handlers as potential vectors for the spread of sars-cov-2 (fao, 2021c). depending on the surface, the virus can live for a few hours up to a few days (van doremalen et al., 2020). the centers for disease control and prevention (cdc) advises washing and sanitizing a variety of surfaces to reduce the risk of spreading germs (seymour et al., 2020). at present time, there is no proof that the sars-cov-2 virus can be spread through eating contaminated food. considering how crucial food is to our life, we can't rule out the potential that it could also serve as a vector for the spread of disease (duda-chodak et al., 2020). effects of covid-19 on the economy of animal production the spread of covid-19 has had far-reaching consequences for the world economy, especially in the areas of animal production and trade in related goods. hence, global economic growth has slowed from 2.9% to 2.4%. rates are expected to drop to 1.5% if the outbreak continues (hussain et al., 2020). likewise, individuals who depend on agriculture (about 60% of the global population) have suffered as a direct result of the covid-19 pandemic (lenzen et al., 2020). the results of covid-19 on the world economy are shown in figure 2. effects on the dairy industry's economy the dairy industry around the world has felt the effects of covid-19. even though milk production has decreased because of the epidemic, the daily demand for milk is increasing. as a result, there was a significant chasm between demand and potential supply. producers of dairy products in the united states lost millions of dollars when they had to dump 4 million gallons of fresh milk in the trash during the first week of april 2020 because they couldn't get it to market (newman and bunge, 2020). canadian dairy farmers were forced to give up producing fresh milk because of a shortage of markets, the inability to safely store their product at home, and a dearth of processing plants (weersink et al., 2020). as a result of the market closure caused by the covid-19 outbreak, dairy farmers in bangladesh were severely impacted financially (zabir et al., 2020). milk prices have dropped drastically during covid-19 as well. as a result of covid-19, fresh milk in bangladesh has been dumped, costing the country 67 million dollars (begum et al., 2020). nepal has also lost $17 million in dairy product sales (poudel et al., 2020). as a direct result of the covid-19 epidemic, pakistan experienced a drop in revenue equivalent to 57.3 billion liters worth of milk and other dairy products (such as yogurt, butter, and ghee, amongst others) (ghafar et al., 2020). indian milk sales have dropped by 50 percent, while milk consumption has dropped by 25 percent to 30 percent (bajwa, 2020). the chinese dairy industry has suffered economically due to problems with production and transportation, a shortage of inputs, and an increase in input prices. milk from approximately 6.25 percent of farms was not accepted by processors, and 27.34 percent of farmers were unable to sell their whole milk production due to a lack of buyers. moreover, 12.50% of farms had to throw out some milk because of the sickness epidemic (qingbin et al., 2020). losses in economic output for the dairy industry can be traced back to the global spread of the covid-19 pandemic, as seen in figure 3. figure 3. the major causes of the economic losses in the dairy industry as a consequence of the covid-19 pandemic source: adapted from fao (2020b) global sustainability research global scientific research 6 the major causes of the economic losses in the dairy industry due to the covid-19 pandemic consists of production and transportation problems; reduced sales of milk to processors; and financial problems. insufficient supply of farm inputs, the increased price of farm inputs, lack of sufficient labor, and deficiency in product transport, all lead to production and transportation problem. moreover, reduced sales of milk to processors are caused by refused dairy products, reduced product quality, reduced product price, and milk dumping. furthermore, the financial problems in the dairy industry created because of the covid-19 pandemic are insufficient operating capital, difficulty in paying salaries and other bills, an increase in accounts receivable, and difficulty in borrowing capital. effects on the economy of the meat industry covid-19 has had an effect on the beef industry all over the world as a result of restrictions placed on imports and exports, a fall in the market, and issues in the processing business (ijaz et al., 2021). the output of beef in the world is projected to decrease by 1.7%, falling from 338.9 million tons in 2019 to 333 million tons in 2020. (fao, 2020a). the united states' 2020 pork output forecast is down 8.9 million tons, or 8 percent, from 2019's projections. beef production decreased by 1% in 2020, compared to 2019 (72.6 mmt) (fao, 2020a). there will be a 7% drop in market pork sales compared to 2019 because 10 million pigs will be removed from the supply chain of pig markets between april and september 2020, causing an economic catastrophe (loss of 2 billion pounds of pork) (ijaz et al., 2021). because of farm and slaughterhouse closures in the united states, beef production dropped by 25% and 43%, respectively (hashem et al., 2020). u.s. economic losses from the beef business are estimated at $13.6 billion (peel et al., 2020). the price of ovine meat fell by 8.6 percent during the covid-19 pandemic, and the prices of other types of meat followed suit (poultry > hog > beef) (pal and kerorsa, 2020). effects on the poultry industry's economy chicken producers felt the effects of the covid-19 pandemic, in part because of emergency pandemic marketing measures (sattar et al., 2021). by the end of april 2020, it is anticipated that covid-19 will have caused record losses for india's poultry business in the amount of 370 million united states dollars. (biswal et al., 2020). there have been observations of comparable tendencies in other south asian nations, such as bangladesh and pakistan. the catastrophic economic crisis that has gripped china has also had a detrimental influence on the export of chicken and other items derived from poultry in that country. turkey temporarily restricted chinese poultry imports (pan et al., 2020). the majority of countries have instituted bans or quotas on some animal imports, including chicken and poultry products. this includes the united states, india, and russia (pan et al., 2020). in addition, six million bangladeshis have direct or indirect connections to the poultry industry (hamid et al., 2016). the commercial poultry industry in bangladesh is growing about 15% annually (mahmud, 2020). not only that, but a great deal of the nation's economy relies on the industry (hamid et al., 2016). nonetheless, chicken farms experienced significant financial losses as a result of the covid-19 pandemic. around $1 billion in lost revenue has been incurred by the bangladeshi government as a direct result of the covid-19 outbreak, which has caused a 35% drop in commercial output of day-old chicks, eggs, and meat (bpicc, 2020). in addition, the industry has lost almost 29% per farm egg (production cost of $0.07 versus selling price of $0.046 to $0.065), even though the price per farm egg was between $0.08 and $0.09 before the epidemic. chicken producers lost 32-40% of their original investment since they could only sell broiler meat for $0.77-$0.80 per kilogram, despite spending $1.17-1.18 per kilogram on manufacturing (mahmud, 2020). covid-19's effects on animal welfare and health global animal health and wellbeing have suffered as a result of the covid-19 limits on farming and veterinary services. quarantine measures taken in response to the covid-19 pandemic may also make it more difficult to conduct regular zoonotic disease surveillance. furthermore, because of these movement restrictions, efforts to monitor and control wild animals and diseases including foot-and-mouth disease, african swine fever, and exotic transboundary diseases have been put on hold (lumpy skin disease, pox virus diseases, japanese encephalitis, and rift valley fever). the global spread of the covid-19 pandemic had a terrible impact on the wellbeing of animals. in addition, global warming and climate change has negative consequences on human and animal health (raihan et al., 2022b; raihan et al., 2022c; isfat and raihan, 2022; raihan, 2023c). animals are more likely to contract various diseases due to their prolonged confinement on farms. as a corollary, the global economic crisis and associated restrictions on human mobility and procedures have had a major impact on the health of animals, as have the suspension of farming activities and veterinary services (hashem et al., 2021; raihan, 2023d; raihan et al., 2023a; raihan et al., 2023b). because farmers have less access to animals (particularly cattle, sheep, and goats) and animal products, they are forced to kill or induce abortions in order to control animal populations and prevent overproduction. pig farmers are aborting sows and killing them inhumanely by methods including suffocation, burning, and shutting off air since consumer demand has dropped and the marketing mechanism has been disrupted (jones, 2020). global sustainability research global scientific research 7 the effects of covid-19 on animal healthcare on farms, in communities, and around the world are already apparent, and they are not good news. as a result, many national and international organizations have had to put off or postpone important activities, initiatives, and projects until they can secure more money. several animal and zoonotic disease prevention, control, and eradication efforts have stalled as a result (fao, 2020a). the following effects on animal health and welfare (deeh et al., 2020) were noted as a worldwide result of the covid-19 pandemic: farming activities one of the drawbacks of covid-19 is that it makes it difficult to keep up with normal animal health tasks like disease diagnosis, routine immunization, and effective treatment of sick animals. prolonged durations of animal lodging on farms lead to stress, immunosuppression, growing stocking density, and multifactorial diseases as a result of decreased movement, higher mortality, lower productivity, and diminishing economic benefits. animal producers were unable to get advice, therefore their animals didn't get veterinary care, because of a shortage of veterinarians and the frequency with which they could see them. the lack and erratic supply of inputs such animal feed additives led to an increase in illnesses as a result of import and export restrictions (vitamins, minerals, antibiotics, and others). for instance, the covid-19 epidemic has caused a kink in the supply chain for animal pharmaceuticals traveling between china (home to multiple pharmaceutical firms) and the united states (hashem et al., 2021). figure 4 shows how the spread of covid-19 threatens the viability of farms. figure 4. the effect of the covid-19 outbreaks on the sustainability of farming operations lab operations and veterinary services it was challenging to import laboratory agents and equipment due to import/export restrictions. because of the social lockdown, veterinary experts in the lab were unable to conduct their jobs because they couldn't get to work. issues with transporting samples from animal farms to labs and a lack of personal protective equipment (ppe) were also factors. often there were no on-call veterinarians or open laboratories. lack of safety precautions, ppe, sample collection gear, laboratory agents, and pcr materials also contributed to an increase in the transmission of animal diseases. local animal health efforts the covid-19 pandemic has caused considerable economic disruption, which has had a substantial impact on a variety of approaches to the prevention and treatment of disease in animals. mobility restrictions hampered efforts to vaccinate, diagnose, and treat many different types of animals and animal diseases. the lockdown impeded the papua new guinea national agricultural quarantine and inspection authority's (naqia) ability to visit affected areas, despite the agency's use of stringent control measures to battle covid-19 (fao, 2020a). global sustainability research global scientific research 8 animal health activities worldwide during covid-19 famous multinational organizations have delayed or canceled their global animal health initiatives due to a lack of financial and logistical assistance. as a corollary, trade and transportation barriers have impeded global animal health initiatives. recommendations for improved animal husbandry during the covid-19 pandemic in order to effectively deal with the covid-19 pandemic, animal husbandry techniques must be improved both during and after the outbreak. protecting the well-being of those who care for animals is a top priority. this includes giving out vaccines when it's safe to do so, encouraging people to eat healthier, and decreasing stress levels. despite this, public confidence in immunization is low because of worries about the safety of the current covid19 vaccines. many people believe untrue statements about the covid-19 vaccine, such as the following: the vaccine is ineffective and causes severe side effects; vaccine material can integrate into human chromosomes; fetal tissue is used in the vaccine's development; and the vaccine contains a microchip or nano-transducer (shehata et al., 2021). achieving high rates of immunization among workers while alleviating their anxiety is strongly encouraged. helping the public understand the need of vaccinations, setting realistic expectations, and using motivational tactics to dispel misinformation about them is a key responsibility of health professionals (verger et al., 2021). a wide variety of animals, both domestic and wild, have been found to have spontaneously contracted sars-cov2 infections. all of these animals are included in this category: canines, felines, minks, ferrets, lions, tigers, pumas, snow leopards, and gorillas. despite the fact that poultry and cattle are resistant to the virus and only moderately vulnerable to it, respectively, these animals may nevertheless impede the progression of the virus and its ability to propagate (shehata et al., 2022). therefore, it is absolutely necessary to utilize the one health approach. furthermore, climate change adaptation and mitigation strategies (begum et al., 2020; ali et al., 2022; raihan, 2023e; raihan et al., 2023c) should be taken for the sustainable development in the the livestock sector. it has been suggested that a number of actions be taken in order to guarantee the production of livestock for the long term: (i) the strict hygienic processing of animal products during marketing and handling; (ii) the improvement of social distance and hand washing hygiene practices in production facilities; (iii) the strict regulations of animal farms regarding biosecurity, isolation, care, visitors, and animal workers; and (iv) the improvement of animal housing and hygiene. conclusion this study presents an overview of the global impact of covid‑19 on the sustainability of livestock performance and welfare. the systematic literature review method was used to conduct this study which includes 44 documents published between 2020 to 2022. the fulfillment of the nutritional requirements of human beings is significantly aided by the production of meat from livestock and poultry. they are absolutely necessary for the achievement of global food security, the sustainable development goals, as well as the economic prosperity and gdp of many agricultural countries. a significant amount of damage has been done to human civilization as well as to ecosystems and the economy as a result of the covid-19 pandemic. the findings of this study revealed that the impact of the pandemic has threatened the sustainability of businesses related to livestock and poultry, which has led to workers in those industries losing their jobs. in light of the effects of the ongoing pandemic and the knowledge gained from it, it is time to rethink the strategies currently in place for the control of pandemics and infectious diseases in animals, particularly those involving significant zoonotic infectious agents. the findings of this study suggest that progressive methods of animal husbandry and agricultural production, which take into account the welfare of animals, should be implemented. in order to identify newly emerging diseases and pandemics, the authors of this study suggest placing a greater emphasis on coordinated efforts directed toward developing a disease surveillance and monitoring system based on the one health approach. it is absolutely necessary to have a robust network on all three levels (local, national, and international) in order to be adequately prepared to stop any further pandemic outbreaks. this study could be useful for making major efforts to improve the existing situation and acquiring knowledge for the future, with a focus on food security through sustainable livestock farming. in addition, this study reveals covid19's impacts on animal welfare and health, which could aid in achieving sustainability in farming activities. in addition, this article provides ideas for enhanced animal husbandry and sustainable livestock production during the covid-19 pandemic. acknowledgement: none funding: none conflict of interest: the authors declare no conflict of interest. references ali, a., rahman, s., & raihan, a.

(2019). urbanization convert traditional energy consumption to modern types and thus rise intensity of energy which reduce pollution such as pollution purification and urban transportation martínez-zarzoso and maruotti (2011). several studies indicates that the environmental kuznets curve in this context is valid. according to this phenomenon, urbanization rise carbon dioxide emission with a rise in urban land and decrease when there is further rise in urban land at the highest level of urbanization li, wang et al. (2016); sadik-zada and gatto (2021). complex mechanism has been debated by which the effect of urbanization on carbon emission has positively or negatively shown zhou, wang et al. (2019);yao, zhu et al. (2021). beside urbanization, most of other activities such as industrialization and production in countries are increased in order to rise economic growth while increase in these activities increase energy demand and rise carbon dioxide emission. the belt and road countries are mostly developing and emerging countries. these countries need to increase industrialization and production to rise economic growth while industrialization and production need high amount of energy. thus, a rise in energy consumption and economic growth leads to high carbon emission discharge. the rapid industrialization in the countries is also observed as urbanization also linked with economic growth and thus its effect carbon emission. in this study, we believe that the specific characteristics of the belt and road countries, the effect of urbanization, energy consumption, economic growth and industrialization on carbon dioxide can be different as a regional difference. several previous studies have conducted studies on the effect of urbanization on carbon dioxide emission however industrialization, energy consumption and economic growth has not been considered while this study considered these closely related factors. the nonlinear association between urbanization and carbon dioxide emission has not been considered in such kind of investigation. this study tests both the nonlinear association between carbon emission and urbanization as well testing for the environmental kuznets curve by introducing the square term of economic growth per capita. considering the belt and road countries data and its specific characteristics and economic level, this study investigates the effect of urbanization, energy consumption, industrialization and economic growth on carbon dioxide emission from 1976 to 2019 using dynamic panel models. the findings reveals that the effect of urbanization, energy consumption, industrialization and economic growth on carbon dioxide emission is positive and it reduce environmental quality however, international trade significantly reduce carbon dioxide emission. this study further confirms the existence of a u-shape link between urbanization and carbon dioxide while the square term of economic growth doesn’t validate the environmental kuznets curve hypothesis. the rest of the paper is structure as follows; literature review is presented in part 2, section 3 is composed of variables and method used, part 4 present results and discussions while the part 5 conclude the study findings and give policy implications. literature review large number of studies have been examined the nexus between different factors with environmental quality proxy by carbon dioxide emission such as economic growth, energy consumption and urbanization. however, these studies have not yet achieved enough conclusions and thus this topic still need investigation. for instance, kong, wang et al. (2021) studied the link between urbanization and carbon emissions in china. the results show a u-shaped association between urbanization and environmental degradation. (bao & lin, 2021) based on provincial data, the spatial vector autoregression model was used to explore the relationship between economic growth, carbon emissions and technological innovation from 2003 to 2017. the results of this study indicate that the study variables were positively correlated. pece, simona et al. (2015) examine the relationship on economic growth and technology innovations in central and eastern european countries. using patents, trademarks, and r&d spending as innovation indicators, we found a positive relationship between innovation and economic growth. (pala, 2019) examined the impact of technology on economic growth in 25 developing countries using a random coefficient model and using r&d and researchers, they reveals that r&d spending had a significant negative impact on economic growth in some countries in the study sample. mukhtarov, humbatova et al. (2020) examine the association between energy and economic growth. the authors used the ardl model and collected the data from 1993 to 2015. the results show that economic growth increases renewable energy consumption. financial development was also found that rises renewable energy. another study by godil, sharif et al. (2020) studied the nexus between institutions, ict and carbon emission using qardl and data from 1995 to 2018. the study shows that economic growth along institutions raises carbon dioxide while ict reduce emission. (chien et al., 2021) also conducted such a study using ardl for the period 1980 to 2018. the study country was pakistan and the authors found that economic growth significantly increases carbon emissions, and the ekc hypothesis is validated. they further show that renewable energy and technological innovation can negatively impact carbon emissions. globalization is a significant source of increased carbon dioxide emissions in pakistan. suki, suki et al. (2022) examine the relationship between renewable energy consumption, technological innovation, and carbon emissions in malaysia. using a bootstrapped ardl model, the findings suggest that using renewable energy can help reduce environmental degradation, and technological innovation can reduce ecological footprint and carbon emissions. their study also confirmed the ekc hypothesis. khoshnevis yazdi and golestani dariani (2019) used indonesia data from 1971 to 2019 and examine the nexus http://www.jescae.com/ global sustainability research global scientific research 14 between urbanization, economic growth and carbon dioxide. using vector error correction model and found the existence of pollution haven hypothesis while there was found a unidirectional causal relationship from economic growth, fdi and economic growth to carbon dioxide emission. other studies have also conduct such investigation such as the study of ponce de leon barido and marshall (2014) validate the findings of above study. these authors conducted a study to examine the nexus between carbon dioxide and urbanization in 80 countries from 1983 to 2005. the authors used fixed and random effects models and reveals that urbanization rise carbon dioxide. chen, liu et al.) studied the nexus between urbanization and carbon dioxide emission by considering the transformative role of government effectives from 1996 to 2018 in oecd countries using fgls and correlated errors models. the authors found the existence of u shape association between urbanization and carbon dioxide. they further evidence the government effectiveness transformative role in this association. some authors also believes that quality institutions also effect the nexus between urbanization, industrialization and carbon dioxide such as wu and madni (2021) studied the nexus between institutional quality, transportation and industrialization with carbon dioxide emission in the belt and road countries from 1996 to 2018. the study implemented panel threshold regression and found the threshold level of institutional quality in the sample countries. institutional quality above the level, carbon dioxide doesn’t destroy the environment while below is related to environmental degradation. most of the studies indicates that urbanization increase carbon dioxide emission. a study is conducted by zhang, song et al. (2021) used china data from 2000 to 2012 to examine the nexus between urbanization, population and carbon dioxide emission. gmm, two stage least square models were employed to the data for analysis and the results illustrate that temporary residence has a marginal influence on urbanization and carbon dioxide emission nexus. likewise, kahouli, miled et al. (2022) explore the association of trade, urbanization, economic growth and carbon dioxide emission. the time period of the study is from 1971 to 2019 and data sample country is saudi arabia. the authors used ardl and vecm models and found that the use of energy and carbon dioxide enhance economic growth while on the other hand, energy consumption degrade environmental quality. martínez-zarzoso and maruotti (2011) used data for different countries groups from 1975 to 2015 and explore the effect of urbanization on carbon dioxide emission. the authors found that urbanization above unity differently affects the income groups. kong, wang et al. (2021) studied urbanization and carbon emissions in china. the results show a u-shaped association between urbanization and environmental degradation. energy consumption and economic growth is also widely debated and most of the previous studies shows that energy consumption drive economic growth as well both energy use for production and economic growth increase carbon dioxide and leads to environmental degradation. a study by gierałtowska, asyngier et al. (2022) investigate the nexus between urbanization, renewable energy and carbon dioxide from 2000 to 2016 in a sample of 163 countries. the authors analyzed the data with gmm model and found u-shape association between urbanization and carbon dioxide. the author further expresses that the effect of renewable energy on carbon dioxide is negative. they also found the existence of ekc hypothesis in the sample countries. (bao & lin, 2021) used provincial data and applied the spatial vector autoregression model to explore the relationship between economic growth, carbon emissions and technological innovation from 2003 to 2017. the findings show that technological innovation, economic growth and carbon dioxide are positively correlated over time. (pece, simona et al. (2015) examine the relationship between innovation and economic growth in central and eastern european countries. using patents, trademarks, and r&d spending as innovation indicators, we found a positive relationship between innovation and economic growth. (pala, 2019) examined the impact of technology on economic growth in 25 developing countries using a random coefficient model and using r&d and researchers, they found that r&d spending had a significant negative impact on economic growth in some countries in the study sample. mukhtarov, humbatova et al.

(2022) examine the relationship between renewable energy consumption, technological innovation, and carbon emissions in malaysia. using a bootstrapped ardl model, the findings suggest that using renewable energy can help reduce environmental degradation, and technological innovation can reduce ecological footprint and carbon emissions. their study also confirmed the ekc hypothesis. methodology this study uses panel data from 1976 to 2019 for the belt and road initiative countries and investigate the nexus between urbanization, economic growth, industrialization, energy consumption and carbon dioxide emission. the study uses both static and dynamic panel models to examine this association. the models include ordinary least square, fixed effect model, two step difference gmm and two step system gmm. however, before the formal analysis, this http://www.jescae.com/ global sustainability research global scientific research 15 study first implemented a panel unit root test to test the stationarity of the data. after performing these preliminary tests, we further conduct formal analysis using static and dynamic panel models. these estimators include ols, fixed-effects models, two-step differencing, and two-step systematic generalized method of moments (gmm). the gmm model was proposed by (arellano & bond, 1991) and is considered a recent application of the topic, and most studies have focused on this estimator when dealing with panel data. first, the study uses static models, ols, and fixed effects to deal with heterogeneity. these static estimators were used to compare the results of the current study with previous studies and to compare the results with dynamic model results. by using a gmm model, it will deal with endogeneity issues related to study variables kinyondo, pelizzo et al. (2021). the system gmm model handles grouping equation differences s at the horizontal level. the instrument specified in the model is the variable delay value of the level in the difference equation. the variables also studied are the horizontal equation and the first difference mean. monte carlo simulations by (blundell and bond, 1998) show that the sgmm model is most effective at estimating this dilemma. the over descriptive constraint test was replaced by the sargan test with the hansen test, and arellano and bond's serial correlation test was also used. most of the results of these tests confirmed our study expectations. hansen test values give recognition and show the effectiveness of the instrument. the baseline empirical models are presented below in form of generalized method of moments. the first equation shows the direct effect of urbanization and economic growth along other explanatory variables while empirical model in equation 2 presented the nonlinear association between the study variables.

(2019); khan, han et al. (2021). urbanization transfers a rural to urban transition and moves an agricultural economy to an industrial economy (muhammad, long et al. (2020). when there is an increase in urbanization, the emission level will increase as inhabitant production and improvement in living standards as well as industrialization. however, it's also been argued that agglomeration in population due to the rise in urbanization enhances the energy use effectiveness and contributes to achieving economy of scale solarin and lean (2016). several studies in preceding literature show that a rise in urbanization leads to a high level of production and raise carbon emission ghisellini and ulgiati (2020); nguyen, nguyen et al. (2018); canh (2019);khan, weili et al. (2022). carbon emissions are expressed as metric tons per capita in terms of environmental quality or degradation. this proxy has been used recently by ibrahim d. raheem (2019) and khan, weili et al. (2021). similarly, it is generally accepted that the independent variable for considering its impact on carbon emissions is urbanization. economic growth is measured as per capita gdp aritenang (2021); bouchoucha (2021, hamdaoui, ayouni et al. (2021); khan, weili et al. (2021). previous studies claim that carbon emission is increased and the environment is polluted by the higher economic growth (danish et al.,2018c; ozcan and apergis (2018). likewise, it's been argued in previous research that a rise in economic growth rise carbon emission and degrade environmental quality. krueger and grossman (1995) ; apergis and li (2016); bai, feng et al. (2020) indicate that per capita income is a vital factor that affects the level of carbon emission. several studies in the preceding literature used the square terms of gdp per capita to testify to the environmental kuznets curve stern (2004); mader (2018). the environmental kuznets curve indicates that in the initial stage of growth rise carbon dioxide while when the country reaches a certain level of development, the emission level goes down. based on the preceding studies, this study also adds the quadratic function of economic growth to test the non-linear effect of per capita growth on carbon dioxide emission. table 1. variables description variables description symbols carbon dioxide emissions (metric tons per capita) co2 urbanization taken as total population urb per capita gross domestic product gdp industrialization ind energy consumption enr trade tr table 2. descriptive statistics variable mean std. dev. min max co2 4.325272 4.150806 0 26.89927 urb 51.15108 18.30245 6.668 92.501 gdp 2.940403 5.59511 -45.32511 24.97367 ind 30.62608 8.436977 12.17161 64.00978 enr 1822.165 1299.566 105.4537 6232.732 http://www.jescae.com/ global sustainability research global scientific research 16 tr 82.0442 39.42683 8.384615 220.4068 table 3. correlation matrix co2 urb gdp ind enr tr co2 1.0000 urb 0.7289 1.0000 gdp -0.0893 -0.0814 1.0000 ind 0.1557 -0.0247 -0.0134 1.0000 enr 0.9569 0.7480 -0.0814 0.1047 1.0000 tr 0.2726 0.2540 0.0615 -0.0430 0.3429 1.0000 results and discussions panel unit root tests before the formal analysis using static and dynamic panel models, the stationarity of the variables was firstly checked employing cadf and cips unit root tests. these are second generation tests where its is assumed that each time series in the panel is distributed across each cross sections. table 4. second generation panel unit root results cips cadf variables i(0) i(1) i(0) i(1) co2 -1.667 -3.575 *** -0.284 -3.831*** urb -1.629 -2.402*** -2.547*** -2.110** gdp -3.641*** -5.167 *** -3.064*** -4.299*** ind -2.308 -5.070 *** -2.049 -3.723*** enr -1.310 -4.093*** -0.891 -3.130*** tr -1.793 -4.813*** -1.834 -3.931*** note: **, *** shows significance level at 5 percent and 1 percent respectively pesaran (2007) proposed second generation tests based on average lag and first difference of single series to enhance adf regression. thus, the single common factor is filtered out. there is a unit root in the panel in each country and thus it is tested alternatively the countries differences. the results are presented in table 4. all the variables are stationarity in first difference and in level. after checking the stationarity of data, this study further forward to the formal econometric analysis using static and dynamic panel model. table 5 present the direct effect of urbanization on carbon dioxide emission. the results indicates that the lagged dependent variable carbon dioxide is positive significant and the ar1, ar2 and sargan test also fulfil the model requirements. the findings shows that the sample countries urbanization leads to high carbon dioxide emission and worsen environmental quality. considering the twostep system gmm results, a rise in the level of urbanization in the belt and road countries increase carbon dioxide emission by 0.004 percent if urbanization goes upward by one percent. the findings of this study are similar to al-mulali, solarin et al. (2016); khoshnevis yazdi and golestani dariani (2019) regarding the effect of urbanization on carbon dioxide. the findings shows that the sample countries economic growth also leads to high carbon dioxide emission and worsen environmental quality. considering the two-step system gmm results, a rise in the level of economic growth in the belt and road countries increase carbon dioxide emission by 0.027 percent if there is a one percent increase in economic growth. adebayo, adedoyin et al. (2021) found similar results. the findings shows that the estimated coefficient of industrialization is positive and significant that’s leads to high carbon dioxide emission and worsen environmental quality. considering the two-step system gmm results, a rise in the level of industrialization in the belt and road countries increase carbon dioxide emission by 0.006 percent with a one percent increase in industrialization in the belt and road countries. khoshnevis yazdi and golestani dariani (2019) also found that industrialization leads to carbon emission discharge. energy consumption is significant and positive. the estimated coefficient values indicate that a rise in the use of energy in the belt and road countries increase carbon dioxide emission. the findings further shows that when there is increase in carbon dioxide emission with the use of high amount energy worsen environmental quality. more specifically, 0.004 percent increase will occur in carbon dioxide if the use of energy increase by one percent. the findings confirm that energy use in the belt and road countries harms environmental quality by producing pollution. international trade variables produce positive and significant coefficient. thus the coefficient indicate that it reduce carbon emission and rise environmental quality. the findings shows that if there is increase in international trade in the sample countries will support the environmental quality enhancement. specifically, taking the two-step system gmm model results, if a percent increase in the belt and road countries international trade occur, the environmental quality will be risen and the carbon emission will be reduced by 0.001 percent. khoshnevis yazdi and golestani dariani (2019) found opposite results for asian countries. http://www.jescae.com/ global sustainability research global scientific research 17 table 5. urbanization and carbon dioxide emission variables ols fixed effect 2steps difference gmm 2steps system gmm urbanization 0.009*** 0.009*** 0.003 0.004** (0.003) (0.003) (0.011) (0.004) economic growth -0.006*** 0.006*** 0.003*** 0.027*** (0.002) (0.002) (0.000) (0.000) industrialization 0.029*** 0.029*** 0.015*** 0.006*** (0.002) (0.002) (0.002) (0.001) energy consumption 0.002*** 0.002*** 0.001*** 0.0004*** (4.320) (4.430) (4.370) (3.365) international trade -0.003*** -0.003*** -0.002*** -0.001* (0.000) (0.000) (0.0003) (0.0002) 𝐶𝑂2𝑖𝑡−1 0.250*** 0.804*** (0.005) (0.012) constant -1.195*** -1.171*** 0.001 (0.228) (0.148) (0.002) observations 936 936 886 925 r-squared 0.903 number of id 37 37 37 37 ar1 -2.01 -2.22 (0.045) (0.027) ar2 -1.42 -0.92 (0.154) (0.357) sargan test 1733.32 1377.01 (0.020) (0.121) note: standard errors in parentheses, *** p<0.01, ** p<0.05, * p<0.1 the findings shows that the sample countries urbanization leads to high carbon dioxide emission and worsen environmental quality. considering the twostep system gmm results, a rise in the level of urbanization in the belt and road countries increase carbon dioxide emission by 0.081 percent if urbanization goes upward by one percent. as the effect of urbanization is positive and rise carbon dioxide emission however the estimated coefficient of the square term of urbanization shows that this coefficient give significant but negative sign thus indicates that urbanization will significantly reduce carbon dioxide emission when its reach a certain level in the belt and road countries. thus, the findings confirm that there exist a u-shape association of urbanization and carbon dioxide emission. the findings shows that the sample countries economic growth also leads to high carbon dioxide emission and worsen environmental quality. considering the two-step system gmm results, a rise in the level of economic growth in the belt and road countries increase carbon dioxide emission by 0.027 percent if there is a one percent increase in economic growth. consistent with findings from zoundi (2017); (h. khan, weili & khan, 2021b); economic growth increases emissions, further evidence from more researchers (chien et al., 2021); adebayo, adedoyin et al. (2021). economic growth reduces environmental quality. (usman, alola, and sarkodie, 2020) also claim that economic growth puts upward pressure on the ecological footprint. khoshnevis yazdi and shakouri (2017) obtained the opposite result. as the economic growth is positive and significant increase carbon dioxide however this study also tests the environmental kuznets curve by taking the square of economic growth per capita. by checking the ekc hypothesis whether economic growth still increase or reduce emission when the countries reach a certain level of development, the results did not validate this hypothesis as the square term coefficient gives positive and insignificant results. the findings shows that the estimated coefficient of industrialization is positive and significant that’s leads to high carbon dioxide emission and worsen environmental quality. considering the two-step system gmm results, a rise in the level of industrialization in the belt and road countries increase carbon dioxide emission by 0.001 percent with a one percent increase in industrialization in the belt and road countries. the effect of energy consumption on carbon dioxide shown positively by the coefficients. thus, a rise in http://www.jescae.com/ global sustainability research global scientific research 18 energy use increase carbon dioxide. the findings further shows that when there is increase in carbon dioxide emission with the use of high amount energy worsen environmental quality. more specifically, 0.004 percent increase will occur in carbon dioxide if the use of energy increase by one percent. the findings confirm that energy use in the belt and road countries harms environmental quality by producing pollution. table 6. nonlinear association between urbanization and carbon dioxide variables ols

p<0.1 conclusion the current study examines the linear and nonlinear effect of urbanization on carbon dioxide emission by including industrialization, energy consumption and economic growth in this association. the belt and road countries data for the period of 1976 to 2019 have been collected from the world development indicator and employed generalized method of moments estimator for analysis. the findings shows that urbanization, industrialization, economic growth and energy use increase carbon dioxide emission and degrade environmental quality however the effect of international trade on carbon dioxide emission is negative thus shows that international trade significantly reduce carbon emission and leads to environmental quality. the study further found the u-shape association between urbanization and carbon dioxide emission however the environmental kuznets curve is not validated in this study shown by the square term of per capita gdp. from the findings, this study concludes that there is high level of urbanization in the belt and road countries and migration from rural areas to urban areas. this migration to cities effects the environment in the belt and road countries in several ways as the urban population increase, there will be increased air pollution, waste materials in cities and high population which worsen environmental quality. this urbanization in the belt and road countries can rise economic activities in cities however there is worsen environmental consequences. however, this urbanization in the sample countries increase pollution and worsen environmental quality in the initial stage while its will rise environmental quality when the urbanization reach a peak level. likewise, energy consumption for production and industrialization rise carbon dioxide emission in the belt and road countries as these sample countries are still developing or emerging countries that need to rise economic growth and living standard. thus, increase energy use increase economic growth while both economic growth and energy rise carbon dioxide emission and degrade environmental quality. the environmental kuznets curve isn’t validated so thus it’s a challenge for the belt and road countries to considered the environmental consequences while rising economic growth through production and industrialization that require high amount of energy. the solution maybe that the countries http://www.jescae.com/ global sustainability research global scientific research 19 need to invest in renewable energy to rise its use in production and industrialization so thus environmental degradation can be decreased as energy consumption, industrialization and economic growth all positively effect carbon dioxide in this study. the countries are suggested to reduce the rapid growth of urbanization in order to control the rapid deterioration of environmental quality in urban areas. likewise, the countries need to adopt strategies to use renewable energy in production and industrialization process to thus can minimize environmental consequences and well can attain economic growth. in case on the effect of industrialization on carbon emission, the countries should not fully be focused on increased industrialization in the initial stage to boost economic growth. alternatives should be investigated to keep economic growth increasing and to protect environmental quality. the international trade should be more advantageous to rise economic growth as well to increase renewable energy which can be the solution to economic growth and environmental problems. the findings concludes that most of variables in this study leads to high carbon dioxide emission except international trade and thus need proper attention. however, urbanization is beneficial for economic growth and the u-shape association between urbanization and carbon emission is also found thus indicates that its can rise environmental quality in later stages when its reach a higher level. while on the other hand, the economic growth ekc hypothesis is not validated thus the countries need special attention to economic activities. this study is limited to the variables used. future study may include institutional quality indicators and governance which may give important suggestion regarding economic growth activities such as the role of governance and institutions in conducting environmental regulation and economic activities rules to control the harmful effects of these factors on environmental quality. acknowledgment the authors are thankful to

study incorporating lessons learned across eight countries syed asad ali shah1*, syed ali mujtaba zaidi2 1riphah international university, islamabad pakistan; asad.shah@live.com: https://orcid.org/0009-0007-8182-8502 2anthro insights; mujtaba.e3@gmail.com corresponding author: syed asad ali shah; asad.shah@live.com received: 04 april, 2023, accepted: 05 may, 2023, published: 13 may, 2023 abstract the sustainable development goals (sdgs) provide a comprehensive framework for addressing social, economic, and environmental challenges facing countries around the world. the role of parliaments in implementing the sdgs has been widely recognized, but the extent of their impact remains uncertain, particularly in developing countries such as pakistan. this paper aims to investigate the role of parliament in implementing the sdgs in pakistan and to draw lessons from other countries that have successfully integrated the sdgs into their legislative processes. to achieve this objective, a qualitative research design was employed, which included a comprehensive analysis of lessons learned from other countries. the findings suggest that while the pakistani parliament has taken steps towards aligning its policies with the sdgs, there is still a long way to go in terms of effective implementation. lessons learned from other countries indicate that parliamentary oversight, public participation, and capacity building are key factors in successful implementation of the sdgs. the paper concludes with a series of recommendations for enhancing the role of parliament in implementing the sdgs in pakistan. keywords: sdgs; parliament of pakistan; implementing sdgs; developing countries; environmental challenges introduction in 2015, countries adopted the 2030 agenda for sustainable development and its 17 sustainable development goals, building on the success of the millennium development goals (mdgs). however, the sustainable development goals (sdgs) are a blueprint for achieving a much more sustainable future for all people (oecd, 2017). the main purpose of the sdgs was to address the global challenges being faced by international communities, and poverty eradication is the overarching target of this new agenda. a few of the other issues include inequality, environmental degradation, illiteracy, peace, and justice. each goal interconnects with the others; therefore, it is important to incorporate all 17 goals and leave none unaddressed (hák et al., 2016). moreover, these new goals are unique in their nature as they call for action by not only the poor or developing countries but also the rich-income countries to promote long-term sustainability, inclusive development, and prosperity while protecting their environment. furthermore, goal 16 (goetz & jenkins, 2016), also known as the governance goal, reflects the inter-parliamentary union's (ipu’s) and united nations development program's (undp’s) long-held view that democratic governance is not only an end in itself but also a means to achieving sustainable development through strong legislative and other important national institutions (kettunen et al., 2018). with the advent of the sdgs, the global community has turned its focus to the question of their effective implementation, both at the national and international levels. to ensure the successful implementation of sdgs, there is a need for an effective structure of procedures, functional institutions, and legal frameworks to not only promote but also implement sdgs to achieve desired results in the long https://doi.org/10.56556/gssr.v2i2.481 global sustainability research global scientific research 48 run (kaushik, 2019). each country will have its own level of prioritization of the goals/targets according to its capacity, understanding, and circumstances; therefore, countries must be provided enough space to determine and implement the goals they feel are most important to them. moreover, it is not necessary that all 17 goals are relevant to every country; however, a strong commitment towards achieving them and effective implementation policies must be made by the national actors, including the parliament, for the accomplishment of those targets that are applicable in their case (oosterhof, 2018; kettunen et al., 2018). therefore, with the help of the national parliament, countries should translate global sustainable development goals into national sustainable development targets, each according to their needs (hassan, 2022). it is perhaps true that a country’s parliament can act as a catalyst in implementing the sdgs, as it is widely believed that without a political will, the probability of success of progressive reform in any country is almost equal to null. therefore, for the implementation of the sdgs through an effective institutional structure, the political environment of that particular country should be conducive to such progressive changes (biermann et al., 2022). the issue is that the political arena, for the most part, is dominated by self-interests at the cost of the common good/interest which hinders the proper functioning of our legislative or administrative processes (ugoani, 2017). therefore, the 2030 agenda for sustainable development puts emphasis on localizing sdgs in national practices by coordinating the already existing national policies towards a common target that fulfills the agenda of "green growth" (lee et al., 2016). each country will therefore have to identify its own priorities in this regard and move towards localizing such targets with the help of parliamentarians and national actors for effective implementation. moreover, the national development plans of countries should be adjusted by the sustainable development agenda (meuleman, 2021). these new development plans should encompass all possible dimensions of inclusive growth by tilting towards a much more holistic policy intervention against antidevelopment-related challenges, i.e., poverty. the sdgs provide an opportunity for all parliamentarians to illustrate their focus and commitment towards public welfare and well-being and the improved health of the environment. furthermore, the sdgs have laid down a framework based on which national actors can pursue their own targets and move towards prosperity (chungong & general, 2018). it is of great concern as to how parliament can play a role in the implementation of the sdgs. parliament is a key institution under which a state runs, the legislative body is responsible for making laws that describe the rights and obligations of state-actors towards one another, which enables a state to function properly. the parliament also plays an important role in the budget allocation process, as they approve how much and where the budget should be allocated (hege & brimont, 2018). as not only the lawmakers but also the elected representatives of their people, parliamentarians have a major role to play in promoting people-centered development; therefore, parliamentarians must ensure their citizens' needs and interests are being fulfilled through government-initiated programs or plans (adiputri, 2021). moreover, the emphasis on the importance of parliaments and stakeholders getting involved in the national implementation of sdgs became stronger after the first review of the un of mdg implementation in 2005; it was argued that it was extremely important that these goals were not being implemented in isolation, further arguing that engagement of the parliament would lead to much more progress in the country (adiputri, 2021). undoubtedly, parliamentarians are responsible for supporting and monitoring the implementation of the sdgs within a country and promoting the 2030 sustainable development agenda (lee et al., 2016). parliamentarians have a special role to play in goal 16 of the sdgs, which is “sustaining peace and good governance,” as they are the promoters of peace and justice for all and responsible for building effective and accountable institutions at local levels (hope, 2022). this goal can only be completely achieved through the participation of parliamentarians through effective law-making, representing the interests of the public, and ensuring accountability and inclusiveness through proper monitoring (kettunen et al., 2018). the presence of accountable and transparent institutions that take timely actions will guarantee proper implementation and desired outcomes, as implementation rests critically on accountability. therefore, in order to achieve national sustainability goals, parliamentarians must look into unexplored areas to improve the effectiveness of their systems and processes (guha & chakrabarti, 2019). an inclusive process can help nationalize and institutionalize the sdg agenda. in this process, a national sdg group is established that is responsible for providing guidance regarding the implementation of these goals. the parliamentarians are also included in these group activities, as their participation can help incorporate nationals’ views and provide institutional support (fitsilis & de vrieze, 2020). global sustainability research global scientific research 49 figure 1. proposed elements for implementation of the sdgs moreover, the national development plans are reviewed by the governments to ensure they are in accordance with the sdgs for achieving inclusive growth in the country. public participation and consultation would further help in the efficient and effective implementation of national development targets. lastly, monthly progress reports by the governments could be helpful for monitoring and evaluating the status of targets post-implementation to see if they are on track (walshet et al., 2019). the proper implementation of the sdgs depends on the following tools at the national level, as mentioned in figure 1. all four dimensions that enable the implementation of the sdgs can be managed by the parliament. law-making behaves as an enabling tool for the national implementation of sdgs in a way that a country’s legislature that promotes equality, a pro-poor policy agenda, inclusiveness, public accountability, and local participation in decision-making can better ensure the national preparedness towards achieving sdgs (fitsilis & de vrieze, 2020). therefore, parliamentarians must be mindful of the kind of legislature their governments have proposed in the country and whether or not it promotes human rights. moreover, the successful implementation of the sdgs depends on budgeting. the parliamentarians should carefully engage in this process by evaluating how much of the government funds are being allocated to their national sdgs and identifying if sufficient funds are being allocated, especially to areas that are vulnerable and socially excluded (fitsilis & de vrieze, 2019). monitoring and evaluation includes the pre and post assessment of government policy interventions in achieving national development plans, m&e will help national actors keep track of the progress of their national sustainable development targets. lastly, local participation and representation act as an enabling tool in pointing out gaps and weaknesses in the national implementation of the sdgs, as local citizens and stakeholders can bring forward their wider concerns and how they can be effectively met (tam, 2022). a self-assessment toolkit designed by the interparliamentary union in order to support parliaments in becoming “fit for purpose” and carrying out their prime functions of legislation, budgeting, and representation on the sdg agenda. this self-assessment mechanism is used as a tool to provide assistance to parliaments around the world for their preparedness to firstly engage with the sdgs, look for different strategies, processes, and mechanisms that will ensure and support the implementation of the sdgs (oosterhofm, 2018). parliamentarians will get to identify multiple opportunities, practices, and gaps that need to be filled; as a result, they can easily institutionalize the sustainable development agenda in their national policies and legislative processes. moreover, self-assessment may help governments identify their capability and capacity in terms of their preparedness for involvement in the 2030 agenda and implementation of the sdgs in their respective countries. it will allow the governments to realize where they currently stand and where they want to go (bexell & jönsson, 2022). furthermore, for the parliaments to stand strong on their human rights agenda, they need to include women and other minority groups within the country either through new electoral laws under which new deserving candidates could be hired or through participatory local participation & representation implementation of sdgs monitoring & evaluation law and order budget allocation global sustainability research global scientific research 50 development. this way, the issues captured by the sustainable development targets will have legitimacy, as now the citizens will demand them (dirth & zondervan, 2019). on october 15, 2017, the inter-parliamentary union (ipu) and the united nations development program released the second global parliamentary report; the aim of this report was to highlight the role of parliament in the implementation of sdgs around the globe (chiniaeva & chiniaeva, 2021). additionally, the 2030 sustainable development agenda has also emphasized the role of parliament in holding its government accountable for actions taken to eradicate extreme poverty and work towards green growth (bexell & jönsson, 2022). according to the report, the parliamentarians are given a golden opportunity to increase their participation and engagement in government-led actions to promote sustainable development in the country through proper implementation. since the role of parliaments is also law-making, they can easily translate the language of the sdgs into their national law, which will compel the government to take initiatives and timely actions (mulholland, 2017). during the declaration of the 2030 sustainable agenda, it was clearly stated “we acknowledge the essential role of national parliaments through their enactment of legislation and adoption of budgets and their role in ensuring accountability for the effective implementation of our commitments.” the sustainable development goals partnership platform has also initiated the idea of having a parliamentarian assembly for the implementation of sdgs on a voluntary basis, in which parliamentarians and other actors will join hands to advocate the efforts to implement sdgs in national plans or legislations for their effective implementation (tam, 2022). methodology this study adopted a case study research methodology that included a thorough examination of lessons (case studies) from parliaments in other countries. the synthesis of the aforementioned study designs creates a thorough analysis. the goal of the current study was to develop lessons learned on the function of parliaments in implementing the sdgs. the field of sdg interactions has rapidly advanced since the adoption of the 2030 agenda in 2015, but the field is still relatively new. this paper could serve as the basis for the future research studies. data triangulation was employed to ensure the validity and reliability of the findings. this process has been found to be helpful in corroborating findings, supplying more complete data, and improving comprehension of the subject matter under consideration. the insights derived from comparative case studies were synthesized to formulate a set of recommendations for enhancing the role of parliament in implementing the sdgs in pakistan. lessons learned from other parliaments the ipu is actively supporting parliaments in assessing their capacity to work on the sdgs in fiji, mali, djibouti, serbia, with namibia, kenya, and sri lanka in the pipeline, to name but a few (nanda et al., 2020; guet et al., 2020). we have organized regional seminars for parliaments in the asia pacific region, sub-saharan africa, central and eastern europe, and central asia, and the list goes on. we also promote parliamentary engagement and contributions to country sdg reports to the un, a process that takes place every summer at the un in new york. i have just come from this year’s session, where there is growing evidence that governments and parliaments are working together to move forward with the sdg agenda. that is a good lesson worth emulating (sherr et al., 2020). samoa the international labor organization (ilo) has been the only tripartite agency of the united nations (un) since 1999, and it brings together governments, workers, and employers from all around the world in order to set labor standards. in 2016, un agencies, in partnership with multiple government ministries of samoa, including the office of the clerk and legislative assembly (ocla), held a special workshop aimed at training new members of the parliament on the 2030 agenda and the sustainable development goals (guerrero-ruiz et al., 2021). malaysia malaysia is one of the countries facing issues with food security. many rice fields in the country are being converted into housing colonies or commercial areas. penang state legislative assembly, yb dr. norlela, state assembly person for penanti, has been working to spread awareness about this issue among the general public. she is doing so through the penang paddy festival, whose goal is to not global sustainability research global scientific research 51 only raise awareness about the hardships faced by paddy farmers, but also shed light on the rapid urbanization of agricultural land in malaysia (abd rahman & yusof, 2020). azerbaijan in a speech on the role of parliament in the implementation of the 2030 agenda, ghulam isaczai mentions how all state institutions in azerbaijan have been actively participating in the implementation of the sdgs. he went on to explain the important role of parliaments as powerful agents of change. in his own words, “parliaments play an important role in the localization, implementation, and monitoring of the sdgs. parliamentarians are close to the people and can serve as advocates, mobilizers, and first-line ‘ambassadors’ for the sdgs. in representing those who elected them, and offering a platform for communication, parliaments can ensure an ongoing dialogue with civil society over the sdgs.” according to him, parliaments must not only incorporate sdgs into national laws but also monitor their implementation by ensuring that the government is held accountable to the people for national progress in terms of achieving sdgs (aliyev, 2019). additionally, parliaments can contribute a great deal by guaranteeing that national development is inclusive and participatory, and that sufficient financial resources have been allocated for its success. isaczai also commends parliaments from around the world that are taking notable action to advance the sdgs. as a few examples, he shares that the parliament of kazakhstan adopted a statement committing itself to the promotion of the sdgs in parliamentary affairs. whereas, the national assembly of pakistan established an sdg task force to promote debates, engage mps, and increase awareness of the sdgs. and finally, the parliament of trinidad and tobago established a new joint select committee on the environment and sustainable development (taghieva, & hashimova, 2019). he concludes his speech by naming a few of the important legislations on which the parliament of azerbaijan has worked: ● the draft legislation on mandatory flour fortification is essential to reduce anemia, especially among women and children. ● review of current legislation on inclusive education in order to build an enabling environment to achieve the sdgs goals on quality education for all. ● the adoption of the new law on the rights of persons with disabilities is important, as it would help to accelerate reforms in this field. ● adoption of the revised law on youth policy will bring current legislation in line with best international practices. united kingdom the uk adopted the sdgs in 2015 and has since committed itself to not only achieving these goals domestically, but to helping other countries do the same. in order to gauge the progress made since 2015, the uk government will be presenting its voluntary national review to the un in july 2019. for this purpose, the international development committee held an inquiry into uk progress on the sdgs, inviting written submissions on the government’s progress on the sdgs (jones & comfort, 2020). finland finland has been one of the most successful states in terms of sdg promotion. it has made commendable efforts in the field, including follow-up reports by civil society organizations on finland and the 2030 agenda, which not only compare the current condition of sdg achievement in the country to un standards, but also highlight what the country must do to improve in areas even if it is already doing well (taghieva, & hashimova, 2019). according to their government report on the implementation of the 2030 agenda for sustainable development, one of the basic principles regarding the implementation of the sdgs is society’s commitment to sustainable development (scsd) the finland we want by 2050. it consists of 8 goals for finland to achieve by 2050, and was updated to align it with the 2030 agenda, making them synonymous. this commitment presents finland’s national interpretation of the 2030 agenda and, thus, is a plan adopted by the entire finnish society to achieve the sdgs. in short, the scsd is an implementation mechanism that enables citizens, businesses, organizations, municipalities, and other stakeholders to participate in the implementation of the 2030 agenda (väänänen & pöllänen, 2021). in 2016, a number of studies were carried out to assess finland’s preparedness to implement the 2030 agenda on global sustainability research global scientific research 52 the basis of indicator-based material, stakeholder opinions, and literature. the results are divided into finland’s success areas, which it must sustain, and critical points, which require urgent action (gade et al., 2022). such studies and reports have been used in the creation of finland’s sdg plan. to further make use of this data, different stakeholder groups, the finnish national commission on sustainable development, and the development policy committee organized multiple events in which proposals were presented by the expert panel on sustainable development to highlight key priority areas for finland, which served as valuable reference material and guidelines for the plan (ylönen & salmivaara, 2021). sri lanka in october 2018, the parliamentary select committee on the 2030 agenda for sustainable development, in collaboration with the united nations development program (undp) and the inter-parliamentary union (ipu) of sri lanka, held a workshop on the critical role of parliament and parliamentarians in implementing the sustainable development goals. the aim of the workshop was to help parliamentarians and their members assess their preparedness to engage with the sdgs and identify additional strategies, mechanisms, and partnerships to support the implementation of the sdgs more effectively. honorary speakers in the workshop included not only members of the sri lankan parliament and notable government officials, but also speakers from the private sector, non-governmental organizations, and youth organizations (wijegoonawardana, 2019). the republic of seychelles despite their small size and many constraints, the groups of islands that make up the seychelles have been demonstrating commitment towards the achievement of the sdgs not just at the international level but in regional partnerships and agreements and in national policies, action plans, and institutional frameworks (baker et al., 2023). through global initiatives such as the global island partnership (glispa), seychelles has been successfully engaging leaders from over 60 countries and has joined hands with overseas territories for island conservation and sustainable use of natural resources. in collaboration with undp seychelles, the national assembly of the country hosted a panel discussion on engaging parliament on the sustainable development goals, to celebrate their first international day of parliamentarianism. members of the department of economic planning and the bureau of statistics gave presentations with regards to sdgs in relation to their respective organizations (gungadeen, & paull, 2020). the 2020 sustainable development outlook for seychelles highlights the current condition of the sdgs in seychelles and how to improve them. using macro-indicators such as economic development and social well-being, the outlook also presents warning trends that may hinder the process of achieving the sdgs. this provides great assistance in formulating the next step to achieve a more sustainable seychelles (etongo, 2022). australia among other efforts, australia has also established a reporting platform that provides official government data on the sdg indicators (allen et al., 2020). in december 2017, the australian senate requested that its foreign affairs, defense, and trade references committee examine and report on the sdgs. this report was to include not only the understanding of sdgs among the wider australian community and government but also a cost-benefit analysis in terms of sdg implementation in the country. additionally, the committee recommended the following to the australian government: ● publish a national sdg implementation plan that includes national priorities and regular reports of australia’s performance against the goals; ● provide an indicator-based assessment to parliament at least every two years that tracks australia’s performance against the goals; ● establish a national sdg secretariat to, inter alia, provide support to the existing interdepartmental committee; ● provide effective coordination of australia’s actions to implement and report on the sdgs; ● develop a framework to ensure that its agencies include the sdgs in their annual reporting by 2020-2021; ● support state, territory, and local governments to create their own plans for the implementation of the sdgs in their jurisdictions; ● partner with “private and tertiary sector” stakeholders to develop and disseminate australian guidance on reporting against the goals; and global sustainability research global scientific research 53 ● identify opportunities to assist small and medium enterprises (smes) to build capacity to access sustainable procurement and reporting systems. what role can pakistani parliamentarians play in implementing the sdgs in pakistan? pakistan has shown great commitment towards the 2030 agenda for sustainable development; moreover, it was one of the first countries to ever approve of the agenda in 2015. on february 16, 2016, the pakistani parliament approved the sustainable development goals as the national development plan (dobrowolski, & sułkowski, 2019). furthermore, it is one of the few countries to create a parliamentary sdgs secretariat under the national assembly; this was indeed a vital step taken to promote sustainable growth in the country. the 18th amendment touched upon several other functions, including that of providing social services to the provincial governments through the federal governments. moreover, pakistan has had panel discussions on the sdgs with other actors involved in order to strengthen efforts to promote and achieve sustainable development in pakistan along with the eradication of poverty (galli et al., 2018). additionally, pakistan’s vision 2025 has established 7 pillars that the country has to achieve, these pillars are in full alignment with the sustainable development goals, therefore, and it can be argued that efforts have indeed been made to incorporate the 2030 sustainable development agenda in the country’s national planning (katramiz et al., 2020). through the involvement of the ministry of planning, government of pakistan, and planning and development departments of provincial governments, along with the support of the united nations development programme, pakistan has launched a five years joint project called "national initiative for sustainable development goals to institutionalize the 2030 agenda” (latif et al., 2022). national and international actors are working towards the coordination, reporting, monitoring, and financing of the sdgs in the country. they are also providing policy prescriptions through r&d (asad, 2019). along with that, the team is also raising awareness among citizens and stakeholders regarding the 2030 agenda and sustainable development targets with the use of different communication tools and a variety of activities (javeed et al., 2021). it is important to remember the already existing mission on which pakistan was built in the first place. while incorporating the historical targets, the parliament should address the sdgs in their relationship. as argued by the inter-parliamentary union, it is important to first sensitize parliamentarians on issues like human rights, gender equality, and human well-being through capacity building (tam, 2022). the first and foremost step should be to inform the parliamentarians and parliamentary staff and train them on their role in the national implementation of the sdgs. once that is done, sessions should be conducted to initiate a debate among parliamentarians and parliamentary staff on the sdgs and their importance and analyze their capacity and preparedness for sdg implementation. an example is the sri lankan initiative (albert et al., 2019). the stronger the parliament’s relations and interactions with its government, citizens, stakeholders, etc., the higher the chances of achieving sustainable growth in the country. additionally, different organizations working within the country can join hands with the pakistani parliament to promote local development preferences and needs through local participation, which can be difficult to identify at the state-level (fatima et al., 2020). finland’s society’s commitment to sustainable development (scsd) the finland we want by 2050 is an implementation mechanism that enables citizens, businesses, organizations, municipalities, and other stakeholders to participate in the implementation of the 2030 agenda (räkköläinen & saxén, 2022). even though the pakistani parliament has established a national plan vision 2025, along with seven goals that are aligned with the sdgs the implementation of sustainable development targets can only be achieved once every citizen takes responsibility to make efforts to promote green growth. the pakistani parliament must not only sensitize the masses at the grass-roots level but also utilize its legislative authority in order to incorporate the sdgs into the national laws of pakistan. doing so will normalize the concept of achieving sustainable development at a personal level, which in turn will compel every individual to work towards it to the best of their abilities (abbasi et al., 2022). the 2020 sustainable development outlook for seychelles highlights the current condition of the sdgs in seychelles and how to improve them. similarly, finland has been reviewing its sdg plan based on the studies conducted within the country regarding success areas that it must sustain and critical points that require urgent action. additionally, these countries conduct multiple events in which proposals are presented by experts on sustainable development to highlight key priority areas for their respective countries, which serve as valuable reference global sustainability research global scientific research 54 material and guidelines for their national agendas (benzaken et al., 2022). conclusion pakistan is still facing a huge number of economic, governance, and security issues. it is important to notice that pakistan was ranked 147 out of 188 countries in the year 2015 on the human development index (hdi), which is the first indicator towards achieving sustainable growth (olsen & zusman, 2014). the human rights agenda is perfectly aligned with the sdgs; therefore, in order for the pakistani parliament to engage itself in the implementation of the sdgs in the country, it must first shift its focus on the human rights dimension. moreover, pakistan ranks 143 out of 144 countries in the gender inequality index; this is also quite alarming, as without inclusive participation in the country, the parliament may fail to establish rules that govern sustainability (brollo et al., 2021). furthermore, pakistani society as a whole lacks a culture of accountability due to high levels of corruption both on micro and macrolevels. in the same way, the parliament needs to safeguard the rights of minority groups and the public, respectively. the pakistani parliament, like all other parliaments, can play a vital role in the engagement and implementation of sdgs in the country through its alignment with the national plan (khan & ali, 2019). however, in order for that to be successful, the pakistani parliament must be empowered to effectively and transparently pass laws in the country, engage itself in the budget allocation process, hold the government accountable for its commitment towards achieving a sustainable pakistan, and monitor the implementation of sdgs by using an inclusive and participatory approach (khan, 2020; xu et al., 2023). acknowledgement: none funding: none conflict of interest: no conflict of interest declared references abbasi, k. r., hussain, k.,

(2013) explained that agriculture is the primary and biggest source of income in rural communities and provides employment to approximately 70 percent of its population. hill (2008) opined that a significant proportion of agricultural task involves moving equipment and materials from one place to another in a wide variety of types and sizes of loads to be moved over different distances and types of terrain. this therefore makes rural transportation a subject of interest (okoko, 2011). transportation demand both modes and means for proper functioning. therefore, several means of transportation exist for both people and goods. these means have evolved https://doi.org/10.56556/gssr.v1i2.367 mailto:salvationeteng@gmail.com global sustainability research global scientific research 31 through the length of time of man’s existence on the planet (mamun and paul, 2017). the means for transporting people, goods and services include air, water and land. among the transportation means listed above, the commonest is land/road transportation (tunde and adeniyi, 2012). road transportation is the movement of goods and people from one place to another on land. however, it is the predominant means of transportation mostly, in rural areas (usman, 2014). describing transportation modes, usman (2013) noted that for transportation to be effective, the mode through which transportation services are provided has to be defined clearly. for instance, air transportation require modes such as aeroplane, helicopters, jets etc. while canoes, ships, boats etc are used in transporting people, goods and services through water. ayodele and babatunde (2015) noted that the modes for land transportation include motor vehicles (cars, lorries, buses, etc.) as well as motorcycles, tricycles and bicycles (otherwise known as para-transit). others include the use of animals (camels, donkeys and horses), and animal drawn carts. while cars, lorries, tricycles and buses may be the predominant mode for intra – city transportation in several major urban areas of nigeria (especially the state capitals), other urban areas and the rural areas mostly use motorcycles for intra-city transportation and even inter-city when distances are short (bassey and eteng, 2021). usman, (2013) further noted that much of rural travel in africa is however on foot or through intermediate means of transport (imt) operating along the local footpaths and tracks. these constitute what starkey (2005) referred to as “invisible” rural transport, consisting of footpaths, cart, cycle tracks and footbridges. rural transportation is determined by a number of factors including the presence of roads, nature of goods transported, income of travelers and so on. however, efficient rural transportation can bring about increase in production. for instance, yaro, okon and bisong (2014) showed that where agricultural products are transported with vehicles such as vans, cars, buses, lorries etc, agricultural production among farmers is likely to be on the increase. equally, where there are large river bodies; boats, canoes and ships may be used for rendering transportation services. abi local government area of cross river state is predominantly a rural area with agricultural activities being the major employer of labour to the residents due to the fertile land. however, there are commercial and agroindustrial activities all of which require transportation services in order to be effective. as a result, various rural transportation means and modes abound in the local government area (lga). for instance, residents in riverine areas such as itigidi and ediba, widely use boats and canoes for transportation while motorcycles, cars, buses, vans, bicycles, carts etc are used for the conveyance of goods and services by others residing and doing businesses in areas that can only be accessible by land. where bridges are constructed across rivers, both water and road transportation modes are used to facilitate mobility. examples include ediba and itigidi. with the above observation, it is clear that transportation in rural areas of abi lga is through different modes and means. therefore, it was necessary to carry out a study of this nature to carefully assess rural transportation in abi local government area of cross river state with particular reference to assessing the level of service. literature review concept of rural transportation rural transportation is the movement of goods, services and people from one place to another within a geographical space called rural. rural areas in nigeria simply refer to settlements with population of below 20,000 (laah, adefila and yusuf, 2014). the above definition may not be applicable in other countries like the united states of america, france, england and russia. for instance, a population of 10,000 people and above constitute an urban area in usa. rural transportation system is the culmination of the totality of the different means and modes through which movement is carried out in rural areas. usman (2014) remarked that rural transport system consists of transport infrastructure, transport operations (services) and the transport users within the rural areas. these include the commercial services and those provided by private owners. therefore, for any transport system to function effectively, there must exist the appropriate infrastructure, transport services, maintenance and traffic management (asian development bank, 2007). the infrastructure includes the road network, tracks, paths and bridges (including footbridges only suitable for pedestrian and intermediate means of transportation). rural transportation therefore represents conscious attempts and strategies towards ensuring that goods, services and people can travel to and from rural areas for business, leisure, tourism etc (usman, 2014). in simple terms, rural transportation refers to the movement of goods, services and people within the rural areas. ajayi (2009) explained that the major transportation in rural areas mostly has to do with the conveyance of farm products and other commodities from places of production to where there are needed. the concept of rural transportation is focused on describing the whole procedures, services and humans that are moving within the rural areas. rural transportation is a key factor in improving agricultural development all over the world (mamun and paul, 2014). this is because rural areas (mostly in sub-saharan africa) are the major producers of agricultural produce for the urban areas and other places. global sustainability research global scientific research 32 in several rural areas in nigeria, the basic modes through which goods, services and people are moved from place to place include trekking, the use of motorcycles, bicycles, canoes, boats and cars. however, the means of transportation are land, water and air. of all the transportation means, the commonest used means is land transportation. among other reasons for preferring land transportation; it is flexible and provides door to door services. in the rural areas, most communities use both water and land transportation to access their farmlands. the modes and means of transportation in rural areas the means and modes through which rural residents transport people, goods and services across rural areas of the world have been documented. basically, available literatures have identified that in developing nations, several rural transportation means and modes combine to make rural living meaningful. in new zealand; reeder, chalmers and langley (2006) observed that people in rural areas are transported through motorcycles, cars and canoes. others trek and use bicycles in moving within rural areas. reeder et al.,(2006) also noted that car ownership is relatively high and as such, over 70 percent of the rural residents are car owners. also, in areas with water bodies, modes such as ships, canoes and boats are predominantly used. in indonesia, hartoyo (2013) observed that cars, lorries, vans and buses are largely used for the transportation of people, goods and people in the rural areas and country sides. this is largely because the roads are accessible and are in good condition. he specifically noted that the use of such transportation modes have vehemently increased production among the rural people in indonesia. also, in riverine areas, goods, services and people are transported through canoes and speed boats. he equally noted that agricultural products from farms that are nearby are simply taken home through foot. in ghana, dinye (2013) observed that motorcycles constitute the predominant transportation mode in rural areas. he showed that rural areas are predominantly low income earners and as such, they mostly lack the financial capabilities of purchasing cars for movement within their localities. he revealed that the motorcycles are not only used by private owners in villages but also, there are used for commercial purposes by the people and therefore provide the means of earning livelihoods to transporters. okoko (2011) noted that in ghana, farmers largely use foot while transporting their goods and services. okoko observed that the increasing use of foot and bicycles is as a result of the presence of deplorable state of roads. in a similar finding, kassali, ayanwale, idowu and williams (2012) observed in oyo state, nigeria that transportation in rural areas is through trekking, use of motorcycles, cars and tricycles. they specifically showed that farmers across rural areas that have accessible roads leading to their farmlands transport their products from farms through motorcycles, cars and tricycles. kassali et al., (2012) showed that trekking was the most widely mode used by rural residents in oyo. for instance, they note that farmers and residents in oyo travelled between 5 and 10km from their villages to farmlands on foot. usman (2014) also noted that in rural kwara nigeria, there is a combination of various transportation services to ensure economic development. for instance, he showed that rural residents travel to places of interest in rural areas by foot (trekking), bicycles, motorcycles and carts. a small percentage of the rural residents use cars within the rural areas. obviously, car owners in rural areas mainly use their cars for private purposes, meaning that motorcycles are the predominant transportation mode for moving people. loads from farms and other places are transported through foot and wheel barrows. he showed that the reasons behind the increasing use of other modes against commercial cars can also be deduced from the deplorable condition of rural roads in kwara. he suggested policy options to bring about improvement in transportation including the provision of adequate funds for road construction and rehabilitation, community-oriented approach to rural road development and introduction of interventions that will improve the provision of rural transport services. similar observations were made by bassey and eteng (2021) in their study in rural cross river state. their study noted that rural residents depend principally on the use of motorcycles for movement. they further observed that rural residents even use motorcycle operation as a means of earning livelihoods being that commercial motorcycle operators render such services to passengers. ther study revealed that commercial motorcycle operation contributes to the development and growth of trading and agricultural activities thus, it is the major mode of transportation. with the observation that motorcycles ease movement as well as provide means for earning livelihoods for rural residents, they suggested that the government should empower the youths in rural areas with motorcycles and grant credit facilities to enable youths purchase their own motorcycles. contributions of rural transportation to socioeconomic development in available literature, rural transportation has been recognized as catalysts to socio-economic development of regions and locations. it has tremendously contributed to the growth of the economy and standardization of the living conditions of rural residents. it should be noted that rural areas are mainly agrarian societies which means that farm produce are generated from farms which require efficient rural transportation system and modes to facilitate delivery. tuan and shimizu (2005) observed that in vietnam, the use of motorcycle in rural transportation has increased the global sustainability research global scientific research 33 number of workers and served as an income generating avenue for operators, while further contributing to revenue generation to the government. for instance, motorcycle owners purchase tickets on periodic basis as well as make necessary registration before being allowed to operate. the registration process contributes to the economic base of the government. in malaysia, sadullah (2006) used multinomial logit model to examine motorcycle ownership and rural transportation and how they contribute to agricultural development. his study shows that monthly household income, car ownership, total number of driving licenses in household and number of household members influenced motorcycle ownership. in the long run, transporters that were involved in delivering services through moving people and goods from place to place were earning reasonable amounts that increase their economic status and also they impact the society with their services. hsu and lin (2007) in taipei taiwan investigated both car and motorcycle ownerships with 336 samples using multinomial logit model. the study was based on the assumption that when both car and motorcycle are owned by the same household each will have a relation of substitution. the study concluded that the main reason for motorcycle and a car was not cost, but utility factors. the increase in reliability as well as convenience of a car, increased car ownership between 12% 29% while it reduces motorcycle ownership. lokesha and mahesha (2016) observed that rural transportation including the use of lorries, cars, carts, motorcycles and so on contribute a lot to ensuring that the socioeconomic lives of rural residents receive a boost. for instance, they noted that when the above and more transportation modes are available, it becomes easy for products to be transported from farm to homes and/or markets. the increase in the options for transporting goods through increasing transportation modes further increases agricultural productivity for the overall benefits of the people. in the long run, the socio-economic lives of the people are improved. ndiyo, bassey and ibia (2016) noted that rural transportation availability is central to the development of the economy of rural areas. obviously, most rural areas depend on agricultural production and primary activities for economic sustenance. this will become increasingly impossible to achieve without the availability of transportation services to ensure and facilitate the conveyance of goods and services from places of production to where they can be marketed and/or consumed. ogunnowo and oderinde (2012) studied the linkages among rural transformation, provision of basic infrastructure and agricultural productivity in rural nigeria with a view to determining how the socio-economic lives of rural residents is enhanced through transportation services. they noted that the transportation services provide the avenue for foods, fibre and other important rural products to be sold to urban areas while making huge profits. the amounts gotten as profits are used for family upkeep among other benefits. according to aderamo and magaji (2010), rural transportation makes it easy for farm lands and towns to be accessed and as such areas with good transportation services are likely to provide their residents with more alternatives to economic survival than the reverse. gbam (2017) observed that rural transportation is not only necessary in the production of agricultural products but further facilitates marketing of the products. he observed that in rural areas of plateau state, transportation services helps in creating market for agricultural product and reduces spoilage and wastage of farm products. as a result, productivity is enlarged as farmers do not have fears of whether or not their products would be bought by traders. gbam further argued that improvement in transportation can encourage farmers to work hard and increase production. problems militating against effective rural transportation services the problems militating against rural transportation services are enormous. for instance the condition of rural transportation infrastructure such as the deplorable state of rural roads and shallow waters constitute problems to rural transportation. tunde and adeniyi, (2012) observed that it is difficult to embark on the movement of goods, people and services in the rural areas due to the bad condition of roads in rural areas of nigeria. they observed that due to the deplorable state of the roads, transporters charge huge amounts as fares while moving goods and people. usman (2014) also noted that the deplorable state of roads negatively affect movement of agricultural goods as motorists are usually unable to access these roads to the farms and back. adedeji, olafiaji, omole, olanibi, and lukman (2014) observed that due to the poor state of rural roads, motorized transport costs are usually high especially during rainy season, as public transport operators hike their fares because of the increased vehicle running cost occasioned by the prevalent bad road conditions. similar high fares are demanded when transporting goods from farms to markets or homes. in most occasions, farmers lack adequate finance to offset such bills thus; they prefer cultivating in small quantities. others use head portage, bicycles, hand drawn carts which are energy consuming and cannot carry bulky loads like vehicles. nsa (2016) lamented that the government of nigeria is doing very little in the aspect of dredging water bodies. as a result of the inability of the government to dredge the water bodies, sophisticated speed boats and electronic canoes cannot be used in the transportation process. nsa revealed that the shallow nature of the waters also do not global sustainability research global scientific research 34 give room for the conveyance of bulky agricultural products as only small capacity canoes and boats can be used for the transportation of goods, people and services from place to place. furthermore, terrain to a large extent can determine the development of transportation infrastructure. ikem (2019) noted that rural areas with difficult terrains are usually relegated in the road infrastructure development of several communities. the reason is because; it would be quite expensive to finance the construction process. however, since the transportation infrastructure is not constructed, residents do not see reasons to purchase vehicles that would be used for transportation. it is in a similar observation that yaro, okon and bisong (2014) showed that inaccessible rural areas convey their products through foot and human energy. there is also the problem of absence of self-help projects. against this backdrop, laah, adefila and yusuf (2014) had noted that the citizens of rural areas are not collaborating in the area of developing projects for themselves. laah et al., (2014) buttressed on this while observing that the residents of rural plateau state are not having effective partnership with the government in the development of rural road infrastructure for their common good. okafor (2011) observed that in rural areas of enugu, there is relegation by the rural residents in the aspect of collaborating in the areas of developing rural roads, maintaining roads and other transportation infrastructure. okafor further remarked in areas with transportation infrastructure, the sustenance of the infrastructure has remained a problem due to unwillingness of the community residents to collaborate in rural project maintenance. however, the inability of the communities to collaborate in the development of projects and their maintenance unveils negative effects of effective use of transportation services. for instance, when the roads are in deplorable conditions, vehicles would likely break down and as such, transporters would be discouraged from offering transportation services. in the long run, there will be shortage of transportation services and the conveyance of goods and people would be difficult. materials and methods study area abi local government area is a border local government area located on the central senatorial district of cross river state. it lies between latitude 5°00’ and 6°30’ north of the equator and longitude 8°00’ and 8°10’ east of the greenwich meridian (akpoke, 2015). it is bounded in the north and west by ebonyi state and on the east and south by yakurr and biase local government areas of cross river state respectively (figure 1). major communities in abi lga include adadama, afafanyi, igonigoni, igbo ekureku , igbo imabana, usumutong, itigidi, ebom, ediba, annong, itigeve, egboronyi, emin ekpon, isongiyang. abi however has a total land mass of 334,53162km2 (abi leeds, 2016) going by the 1991 national population census results, abi local government area had a population of 78,452 persons (national population commission, 1991). current projection with a growth rate of 2.8 percent put the population at 202,010 persons in 2019. the vegetation of abi is characterized by mangrove and rainforest ecosystems which forms part of the rich fauna and flora of the state. the abi soil is predominantly clay in nature. some areas like, ediba, adadama and igbo imabana also have a mix of clay and loamy soil. the soil is fertile for agricultural activities and production of crops such as cassava, yam, maize, groundnut and vegetables. the word abi is coined from the words; agbo (a), bahomono (b) and igbo imabana (i). the above clans formed the group of settlements in abi. the local government area was created on the 21st of september, 1991. it was created from yakurr local government area and has itigidi as its headquarters. abi people belong to the large heterogonous group of upper cross river called ekoi of the bantusan family (abi leeds, 2016). the abi people speak bahomono and agbo languages. the abi people like all patriarchal societies have a rich cultural heritage, elaborately manifested in their traditional dances, festivals, marriage customs, chieftaincy and age grade system which are highly cherished (abi leeds, 2016). farming is the predominant socio-economic activity in the study area. subsistent agriculture is the major practice. most of the residents in the study area are involved in rice, cassava, maize, yam, cocoa yam, groundnut, vegetables and fruit production. a small percentage of people are engaged in businesses and civil/public service jobs; with artisans also constituting a percentage of the population. global sustainability research global scientific research 35 figure 1: map of abi lga on the map of cross river state source: cross river geographic information agency, 2020 methods the survey research design was adopted in this study. this required the design of sample questionnaires among others in the collection of data from the target population. the data collected were presented and analyzed in order to draw global sustainability research global scientific research 36 inferences. the study further employed both primary and secondary data. the primary data include age of respondent, sex, occupation, educational qualification, mode of transportation, amount charged by transportation operators, factors determining choice of transportation mode etc. secondary data were also used. data from this category include population figure of the study area and maps of nigeria, cross river state and abi lga. the primary and secondary sources of data were used in the study. the primary sources of data used in this study include the use of questionnaires, direct observation and oral interviews. the secondary sources of data were published documents. these published documents include the 1991 population of abi lga which was collected from the national population commission area office, calabar, maps from cross river state geographic information agency. unpublished documents including past research works and government reports were used. the population of the study according to the 1991 population was 78,452. the population was projected to 2019 and it resulted to 93,085. this number formed the sample frame for the study. in order to determine the sample size, the taro yamane formula of infinite population was used as follows. n = n 1+n(e)² where; n = sample size n = finite population e = level of significance (limit of tolerable error =0.05) n = 93,085 1+ 93,085(0.05)² n 93,085 1 + 93,085x 0.0025 n = 93,085 232.7125 n =400 therefore the sample size for the study was 400. the stratified random sampling method was adopted in the collection of data from the field. in the light of the above, abi lga was divided into three (3) units. the units were divided using the three major clans that make up the entire abi lga. there are; agbo, bahomono and igbo imabana clans which were considered as units in the stratification process. from each of the units established above, the researcher randomly selected four communities within each unit for data collection. in agbo clan, the communities that were studied were igbo ekureku, itigidi, etani and adadama. in igbo imabana clan, the communities studied were ikpalegwa, lehangha, ebol and ilike. in bahomono clan, the communities studied were anong, ediba, abeugo and afafanyi. the systematic approach was used in distributing the questionnaire to the individual communities as shown in table 1. copies of questionnaire were the major instrument for data collection. specifically, a total of 400 copies of questionnaires were administered in the study area. table 3.1 shows the number of questionnaires that were administered in each sampled community. the questionnaires were distributed in line with the population of the community. in order to achieve this, the ratio of the sampled neighborhoods were divided by the total ratio of the entire sampled neighborhoods and multiplied by the sample size to arrive at the number of questionnaire distributed in each neighborhood. using egboronyi as an example, it was expressed as: n =r/trxs where: n = number of questionnaires to be distributed at each unit r = ratio of the projected population of each unit tr = total ratio of the entire sample unit selected s = sample size n = 5/78 x 400 n = 27 data were also obtained through oral interviews with community heads and youth leaders in the study area as well as the town planning authority in abi local government area. in othertables and charts were used in carrying out the analysis of data that were obtained from the field. the hypothesis was tested using simple linear regression analysis. the hypothesis states that the level of service of rural transportation does not have significant effects on the socio-economic development of the residents in abi local government area. statistical package for social science (spss) was used in conducting the test. the multiple regression analysis formula is as follows; y = a + b x + e. where: y = dependent variable, x = independent variable, a = intercept, b = slope, e = residual (error) results and discussions table 2 revealed that the preferred mode of transporting goods among respondents differ. as seen in the table 209 (55.5 percent) respondents prefer using motorcycle while 13 (3.5 percent) prefer cars. equally, 13 (3.4 percent) respondents use speed boats for movement within the lga. the table also showed that 21 (5.6 percent) respondents travel within the lga with canoes while 134 (35.5 percent) trek within the lga. the modes for transporting goods among the respondents in the study area is presented in table 3. the table shows that 138 (36.6 percent) transport goods with motorcycles while 28 (7.4 percent) transport goods within the lga through cars. the table further revealed that 69 (18.3 percent) transport goods within the lga through canoes and 8 (2.1 percent) use speed boats. those that trek with goods were 74 representing 19.6 percent and 60 (16 percent global sustainability research global scientific research 37 use wheelbarrows. from the table, it is obvious that those that use motorcycles are more. this equally implies that motorcycles are the most used transportation mode in the study area. table 1: distribution of questionnaire s/n unit 1991 population projected population 2019 ratio sample

information in the table revealed that 187 (49.6 percent) respondents were of the view that the service was excellent while 132 (35 percent) said it is high. the table further revealed that 58 (15.4 percent) respondents were of the opinion that it is medium while 16 (4.2 percent) said it is low and 19 (5 percent) said it is very low. from the findings, it was clear that those that depend on transportation modes for their businesses on daily basis were more. this was based on their judgment that the level of service of transportation is excellent and high. by implication, it may be deduced that transportation services are high in the study area. table 5: activity that attract transportation modes activity frequency percentage farming 125 33.2 commercial 198 52.5 others 54 14.3

transportation modes for farming purposes while 198(52.5 percent) use them for commercial activities. the responses of 54 (14.3 percent) respondents explained that they depend on transportation modes for other activities such as tourism, recreation and sporting activities. global sustainability research global scientific research 38 table 6: how rural transportation contribute to economic

transportation is highly beneficial as it provides the means of earning livelihoods as noted in table 6. respondents under this category include motorcycle operators, canoe sailors, drivers and wheel barrow pushers. these persons are principally employed by those they offer services and the means of generating funds is dependent on the services they offer. the table further revealed that 187 (49.6 percent) have been positively effected through the use of transportation modes to the extent that their agricultural practices have been expanded. also, 39 (10.3 percent) respondents were of the view that the constant and consistent use of transportation modes leads to increase in the revenue that is generated by the government. these revenues come in the aspect of tickets and taxation on commercial operators of transportation modes. even more, private owners of transportation modes seek for licensing and renewal of documents (when necessary). table 7: level of socioeconomic

development in the study area. the study showed that 126 (33.4 percent) respondents agreed that the level of socioeconomic development is excellent due to rural transportation while 78 (20.7 percent) respondents revealed that its high while 99 (26.3 percent) said that the level of socioeconomic development is medium. in the views of 56 (14.9 percent) respondents, the level is low while 18 (4.7 percent) respondents say the level is very low. with this information, it is clear that the residents of the study area are taking advantage of the availability of transportation modes to expand development, test of hypothesis the hypothesis formulated for the study was tested using simple linear regression analysis. the null hypothesis states that “the level of service of rural transportation does not have significant effect on the socioeconomic development of the residents in abi local government area”. analysis was based on statistical package for social sciences (spss). the result of the analysis is presented in table 8 the result from the regression test as presented in table 4.15 shows that the calculated significant value was 0.516 which is greater than 0.05. based on this result, the null hypothesis was accepted and the alternative hypothesis was rejected. this implies that the level of service of rural transportation does not have significant effect on the socioeconomic development of the residents in abi local government area. this suggest that the totality of the lives of the people of the study area is not basically dependent on the transportation services in the area. therefore, other activities such as trading, agricultural practices among others may account for the level of socioeconomic development. discussion of findings the various means and modes of transportation in the study area were identified. it was revealed that the predominant mode of transporting goods within the study area is motorcycle. other modes equally exist which include cars, canoes and trekking. the reason for the continuous use of motorcycle is the state of the road which is highly deplorable. obviously, the use of motorcycles above other modes is due to the fact that motorcycles have the ability to be manipulated into roads that are not in very good state. due to the fact the roads in the study area are not in good conditions, residents of the study area prefer moving within the study area with motorcycles. this observation aligns with the findings of dinye (2013) who revealed that motorcycles are the predominant transportation mode in rural areas. dinye noted that rural areas are dominated by low income earners that lack financial capabilities of purchasing cars for movement within their localities. dinye further revealed that the motorcycles are also used for commercial purposes by the people and therefore provide the means of earning table 8: model summary model r r square adjusted r square std. error of the estimat e change

transporters. however, motorcycles are configured to be manipulated on land therefore, land is largely used as means of transporting people and goods in the study area. residents in the study area also trek to locations to deliver goods and services. moreso, the availability of large river bodies in abi lga has promoted the use of canoes for transportation within the study area. the result of the hypothesis has shown that socioeconomic development in the study area is not completely tied to the level of service of rural transportation. this imply that other variables equally contribute to economic development in the study area. instance of such variables may include infrastructure availability such as electricity, water and other job opportunities. nevertheless, rural transportation have contributions only that it is not the sole determinant of socio-economic development in the study area. for instance, the study noted that rural transportation provides residents with the means of earning livelihoods. notably, through rural transportation, the services of motorcycle operators, canoe sailors, drivers and wheel barrow pushers are employed. obviously, the funds they generate are used to aid their livelihoods. equally, transportation contributes to agricultural expansion further revealing in food production at increased level. this is because, energy and travel distances are saved through the use of machines for traveling to farms and markets. this assertion is buttressed by the findings of hartoyo (2013) who showed that the development of roads in rural indonesia promoted agricultural practices and ensure food availability. okoko, (2011) returned that rural transportation in ghana also promoted agricultural activities in ghana. also, transportation contributes to increase in revenue generation by the government in form of vehicle licensing and daily ticket sales to commercial transporters. the problems militating against effective rural transportation services in the study area are poor funding, limiting the regular rehabilitation and upgrading of road. this particular reason has resulted in the presence of deplorable roads and collapsing transportation infrastructure. another factor is the difficult terrain in the study area which demands large sums for fixing of roads further serving as a discouraging factor for the government to commit funds to road development. recommendations in line with the study objectives and subsequent findings, the following recommendations were made; i. since land is the predominant transportation means, the roads in the study area should be rehabilitated regularly. ii. residents in the study area should be encouraged with facilities for mobility such as motorcycles, vehicles and wheel barrows so as to encourage productivity among the residents of the people iii. there is need for diversification of the economy and rehabilitation of more roads within the study area so as to encourage farmers to embark on agricultural productivity. iv. funding for road rehabilitation should be increased by the government. v. finally, other sources of funding such as public private partnerships should be advocated in the road development/rehabilitation process. 5. conclusion the study assessed rural transportation in abi lga. the study specifically identified the predominant transportation means and modes that are used for rural transportation in the study area. the study identified that land is the main transportation means that the residents of abi lga travel within the lga. transportation modes used by the residents include motorcycles, cars, wheel barrows and others trek. as seen in the study area, rural transportation contributes to the development of socio-economic activities, yet, socio-economic development is not completely tied to the level of service of transportation in the study area. this is because some of the residents do not mainly use machines for movement. finally, rural transportation in the area is plagued with problems. the problems basically include weak funding by relevant authorities and weak monitoring/supervision in the road development/rehabilitation process. references abi leeds 2 (2016). abi local empowerment and development strategy 2. a publication of the ministry of local government affairs, cross river state. p191

" (ellen macarthur foundation, 2014, p.02). as not all resources in nature are renewable, companies are forced to pay more for their raw material to avoid stopping their production. (sandoval et al., (2017) affirm that what is involved is to close the cycles of energy, of materials it is not about going against economic growth, but that the resources we have have an intensive use instead of increasing their exploitation ". a circular economy contributes to at least 12 of the 17 goals outlined in the un's 2030 agenda for sustainable development." (ellen macarthur foundation, 2019, p 19). chaves, r. & monzón, j.l. (2018) conceive that the circular paradigm is in the current production system an innovative change, since the idea of regeneration is present in each phase of the production process. (p. 34). "in ec, one of the goals is to increase product life, produce goods with long life cycles, and focus on services rather than products." (eu-lac foundation, 2018, p 8). brook. (2018). expresses that, in europe and asia, the incorporation of this economic paradigm is promoted through the implementation of pedagogical, technological and social strategies. sweden, in 1997 outlined its current energy policy, whose motto was the transition to an ecologically sustainable society, this is evidenced in research such as (moreno et al., 2022; moreno rocha et al., 2022). fulfilling this goal, the european country opted for recycling, its population is characterized by recycling 99% of its organic waste and 88% of inorganic waste and this is how it now produces energy through the "from waste to energy" program. the initiative has proved so effective that sweden now imports tons of waste from other countries such as italy and the united kingdom to supply the 32 energy centers it now owns. in the study advances and challenges for inclusive recycling: evaluation of 12 cities in latin america and the caribbean developed by the economist intelligence unit. (2017) brazil is recognized as one of the pioneers of inclusive recycling in latin america and the caribbean, also highlighting that in buenosaires recycling becomes https://doi.org/10.56556/gssr.v1i2.313 http://www.jescae.com/ mailto:cmoreno7@cuc.edu.co global sustainability research www.jescae.com 2 an activity co-managed by the state and cooperatives, with a joint social responsibility, in the colombian case in bogotá the recyclers become visible and are recognized as providers of the public cleaning service, and are therefore entitled to remuneration. (p. 22) in colombia, resolution no. 1407 of july 26, 2018 aims to regulate the environmental management of packaging waste and packaging of paper, cardboard, plastic, glass and metal." although materials are used through recycling, the disproportionate increase in plastic during the covid-19 pandemic since 2020 is worrying since not being able to recycle all single-use plastic would increase environmental pollution (un news, 2021). the chemist-ecologist michael braungart and the american landscape architect william mcdonough, consider that currently there is no recycling but an undercycling because the raw material is losing value until the usefulness of the material reaches its lowest level, just as in recycling, reduction and reuse do not meet 100% with the objective set by the circular economy (mcdonough and braungart, 2005). therefore, the objective is to analyze pedagogical, technological and social strategies of circular economy as a factor of sustainable development from the perspective of studies of authors that can be replicated in colombia. methodology the focus of this article is qualitative of a propositive documentary type with an inductive method, an analysis of scientific literature was carried out, databases such as dialnet, scielo, google scholar, repository of universities, books, reports of foundations and reports of dane, information was also obtained from primary source through a dialogue with recyclers and owners of deposits of the corregimiento la playa and barranquilla. development for the hellen mac arthur foundation, (2014). the circular economy differs from the mere management of waste and recycling in that theproducts designed and optimized can be reused their components, in this way large amounts of energy and labor are not lost as it happens in recycling, this is what defines the circular economy. (p. 4). the reason why it is considered that recycling does not fully meet the requirements of the circular economy according to mcdonough and braungart (2005) is because raw materials are not designed for this purpose, for this reason, although once their useful life cycle is finished they are transformed into new materials, the result is a low quality product. when plastics other than those used in soft drink or water bottles are recycled, they are mixed with different plastics to produce a lower quality hybrid, which ismolded amorphously and cheaply. in colombia, dane in its first circular economy report of 2020 defines the circular economy such as: "a system of production and consumption that promotes efficiency in the use of materials, water and energy; taking into account the resilience of ecosystems and the circular use of material flows through the implementation of technological innovations, alliances and collaborations between actors, and the promotion of business models that respond to the fundamentals of sustainable development". pag (7) although the circular economy is frequently associated with recycling and perhaps the power of this in being transformed into energy as evidenced in research such as (manuel et al., 2022), this is not the only way to contribute to the sustainable development goals (sdgs), other ways to contribute to these objectives is the creation of companies whose purpose is the ec, to achieve this end they focus on the design of innovative products that can be reused, repaired, remanufactured or recycled, this strategy allows them to be more competitive by reducing investment in virgin raw materials. the dane in its first circular economy report published on august 5, 2020, marks the starting point of the siec circular economy information system that will integrate technical and statistical information to generate new knowledge and guide the execution of the pact for sustainability, and the public policies that are formulated in this regard. this report presents indicators of statistical information that are classified into four components that allow analyzing some topics of interest to the colombian case such as: extraction of environmental assets, production of goods and services, consumption and use, closure and optimization in the life cycles of materials and products. in the second report published on december 11, 2020, it presents 23 indicators of available statistical information and the classification of the components remain the same as the first report. in the third circular economy report published on july 28, 2021 , there are four new components, these are: demand for environmental assets and ecosystem services, conservation or loss of value of materials in the productive system, pressure on ecosystems due to the disposal of waste and the fourth is factors that facilitate the circular economy. without departing from the purpose of the first two reports, this is the result of the statistical articulation undertaken by dane within its technical directions, but also in the context of the national statistical system sen. in the fourth report published on december 2, 2021, the circular economy indicators were categorized into the following four components: demand for environmental assets and ecosystem services, conservation or loss of value of materials in the productive system, pressure on ecosystems due to the disposal of waste and factors that http://www.jescae.com/ global sustainability research www.jescae.com 3 facilitate the circular economy. this report includes for the first time information about the indicators of area modified by type of forest cover, sustainable extraction, extraction and use of timber resources, in natural forest, pressure for fishing and average size of catch and distribution by size. the fifth circular economy report published on june 23, 2022 maintains the following components: demand for environmental assets and ecosystem services, conservation or loss of value of materials in the productive system, pressure on ecosystems for the disposal of waste. in the first report, the indicator percentage of households that make separation in the source of waste expresses that in 2018 39.9% of households (6.2 million) of a total of 15.5 million, made separation at the source of some type of waste and households by departments that classified waste in a higher percentage were: bogotá d.c, antioquia, caldas, santander, cundinamarca, boyacá, casanare, valle del cauca, putumayo, huila and nariño, while in the fourth report it appears that between 2018 and 2020 the highest levels of waste classification according to the departments is headed by bogotá d.c. and in the departments of santander, cundinamarca, boyacá, putumayo, antioquia and cauca. table 1. components that group the circular economy indicators first report august 5, 2020 second report december 11, 2020 third report july 28, 2021 fourth

in the country, it is mentioned that in the urban area the type of fuel that is used in greater proportion is natural gas, while in rural areas it is propane gas and firewood or wood. with regard to the collection or disposal of garbage, the second report reports that in 2019 81.2% of a total of 15,999 households had a garbage collection service through the cleaning company, while 12.6% of households burned garbage and 6.2% disposed of garbage by another means. in 2018, the number of households that had the garbage collection service was 0.51% lower than in 2019 and the percentage of households that burn garbage remained the same. page 7 in the fourth report regarding the way households dispose of their waste, a difference in the data can be observed when compared with those of the second report. in 2018 80.7% of households had a toilet service, in 2019 81.2% of households had a garbage collection service through the cleaning company and between 2019 and 2020 the fourth

european countries such as japan, south korea, germany, norway, spain, italy and switzerland among others, in order to close the cycles of resources and be reused all its components. with respect to private companies, they must establish as strategies the accompaniment of campaigns that promote the importance of the adoption of ec in economic, social and environmental development. to achieve this end, the training of committed leaders convinced of the benefits of the circular model is essential. kowszyk and maher in their case study for the eu-lac foundation (2018) highlights the importance of dreamy, idealistic and courageous leadership at the head of companies, an example of the importance of assuming this attitude is presented by this study in the company neptuno pumps of chile where its executive director petar ostojic decided to act as a promoter of ec in the media of chile and latin america to raise awareness about the importance of this business model, also as a strategy went to the use of social networks, the organization of talks and presentations in companies, universities and other institutions, this work that was of personal initiative led him to receive awards and recognition for his achievements in the field of ec by latin american governments and the world economic forum and un agencies. in colombia, resolution no. 1407 of july 26, 2018 aims to regulate the environmental management of packaging waste and packaging of paper, cardboard, plastic, glass and metal. in chapter 3 article 11 of said resolution, are among other obligations: promote the incorporation of circular economy guidelines, in the prioritization of alternatives for the use of packaging waste, and support the manufacturer in innovation and ecodesign for the manufacture of containers and packaging with sustainability characteristics. chapter 2 article 9 establishes quantitative targets for producers where "producers shall meet the target of using packaging waste with respect to the total weight of packaging placed by them on the market in the base year," below are the percentages set out in table i of this resolution." table 4. quantitative targets for producers

december 24, 2020, the ministry of environment and sustainable development issued resolution 1342 of 2020, modifying resolution 1407 of 2018. among the modifications are that of paragraph 1 of article 2 of resolution 1407 to indicate that, within the exclusions of this regulation, the packaging and containers of drugs and medicines in general are included, eliminating the reference to primary packaging and containers. article 8 of resolution 1407 is modified by establishing that existing producers as of december 31, 2018, must http://www.jescae.com/ global sustainability research www.jescae.com 5 submit the environmental waste management plan no later than january 31, 2021, thus extending the period that was indicated above and that expired on december 31, 2020 for existing producers as of december 31, 2018, article 16 of resolution 1407 was modified, in this it is established that natural or legal persons who consume or use goods or services, as the last link in the marketing chain must: carry out a correct separation at the source of packaging waste and deliver the separated waste at collection points, requirements are established for producers with returnable packaging systems, with the aim of establishing the returnability efficiency indicator and alternatives to obtain a returnability efficiency certification are included. in order for the process of change not to stagnate, pedagogical, technological and social strategies that can be replicated and that are aimed at empowering cd must always be present. pedagogical strategies having clarity about what the circular economy is allows company directors to transmit the concept of ec to their employees and other actors related to the company, to identify which issues they can lead with their experience and knowledge and in which they can benefit from learning from others, all the challenges they face on the road to greater circularity can be solved (eu-lac foundation 2018). sáez and urdaneta, (2014) suggest in their conclusion that to achieve improvements in solid waste management in latin america and the caribbean requires will on the part of governments, strong investments and continuous education of citizens on the issue of waste use. the organization of conferences and activities in companies, microenterprises and educational institutions accompanied by information on the proper management of solid waste and the contribution that these can generate if they are commercialized, will allow to demonstrate the changes in society. the relevance and applicability of modules to develop recycling projects in educational institutions allows young people to multiply knowledge in their community. from the perspective of romero, (2017), schools are the ones that allow pilot tests, because there is a certain level of plurality depending on their type and location, in addition, the actors involved are repeaters of knowledge within their environment regarding solid waste management. to reduce the strong negative impact generated by the textile industry on the environment, it becomes pertinent that the consumer is aware of the final destination of their garments, peña a (2019) recommends that the will of the consumer is important and that through educational campaigns about raising awareness about the large number of impacts generated by the textile industry, by the abandonment of a garment, its decomposition time, the amount of dyes and microplastics generated as a result of its decomposition. during the i international congress of sustainability organized by knauf in october 2018 in madrid, the abc live interviewed the architect walter stahel he commented that "we always forget that there is a renewable resource: work, human labor. we must produce a better human resource, because if we do not use this resource, we will not move forward. you have to focus on people, on training" the cotec foundation for innovation, in its 2017 report "situation and evolution of the circular economy in spain", is aware of the lack of information and data that allow actions to be taken in search of the adoption of the circular economy effectively. in colombia as in any part of the world, the process of transition from linear to circular is only possible with the presence of leaders who know and recognize that its implementation generates great benefits and that, to achieve results, the first thing to do is to change the mentality of those who run the companies and that of the citizens of all social strata. for soria, (2016) educational strategies are those that allow generating environmental awareness and managing the characterization of waste, in this way the generation of economic income for people dedicated to recycling can be improved by applying a more comprehensive recycling. on june 14, 2019 at the chamber of commerce of medellín, president duque officially launched the national economy strategy, through which it is intended that the country become one of the three most competitive economies in latin america by 2030. to achieve this goal, he emphasized the need to reach the awareness of colombians about the good management of garbage, efficient handling of materials, water and energy, and also encouraged producers, suppliers, consumers and other actors in the productive chain to develop business models that incorporate waste management, efficient management of materials and change in the lifestyles of citizens. technological innovation strategy to achieve the transition process towards the circular economy, it is necessary to innovate in new technologies, processes, services and business models, and to make consumers aware of the importance of changing their behaviors cotec, (2017). currently, the vast majority of companies only have machines that fit the linear economic model and designers focused on products that have as characteristics to become garbage in the literal sense of the word or in the best case be suitable to be recycled losing their quality in each process until losing their value completely. to be able to adopt the ec it is essential to have eco designers who elaborate products that from the moment http://www.jescae.com/ global sustainability research www.jescae.com 6 they begin to create take into account that these should not lose value, but at the same time it is necessary to have machines capable of disassembling the product to consider which parts can be remanufactured. if it is a recycling company, you must have machines capable of identifying and separating each of the materials that compose them. it is important that once the useful life of a product is over, they can decompose in the soil and provide their nutrients to the soil or are food for plants and animals, otherwise they are useful to be reincorporated back into industrial cycles to provide quality raw materials, (mcdonough and braungart 2005) the abc of the orange economy defines it as a tool for cultural, social and economic development that differs from other economies by the fact that it is based on the creation, production and distribution of goods and services whose cultural and creative content can be protected by intellectual property rights, therefore if the orange economy is considered as a tool of economic development, this can support technological creativity so that companies are competitive and can consolidate with innovative technology, therefore it is pertinent that projects supported through the orange economy focus on innovative technology at the service of the circular economy. the development bank of latin america caf (2018), development of a study that allows to know the contribution of innovative technology in the field of solid waste in countries of europe, asia and other countries. the result of this studyor shows the panorama of the state of consciousness of other countries with respect to the circular economy and what is proposed is that a deep evaluation of the possibility of replicability be made taking into account that it adapts to the colombian context. what the report shows is that there are systems that recognize the people who recycle, the type of waste, systems that warn when the containers are filled and these automatically compact the garbage, specialized systems for people with disabilities, machines that give money in exchange for materials that are recycled and luminous screens that inform the user about the classification of waste. proposed social strategy the offer of products that have a programmed useful life is what is known as planned obsolescence, this generates in many colombian households negative impacts on their economy making evident the economic interest on the social interest, the absence of social contribution by these manufacturers is in europe and the same should be in colombia a subject of interest of different social groups. in europe, the spanish technical institute of cleaning (2017), states that the denunciation of different social groups has caused the fight against obsolescence to be incorporated into its agenda, issues such as increasing the coverage of guarantees, the establishment of minimum useful lives, or information to the consumer about the useful life of each product are supported by the new legislation as lines of fight against obsolescence. for most households electronic devices and appliances more than a luxury has become a necessity, therefore, the absence of any of these devices affects the quality of life of many families, being so, the repair positively impacts the economy due to the decrease in costs, therefore, being able to access these is facilitated and has an impact on the social aspect. the contribution of the repair and reconditioning cannot be ignored, however, it must be required that the repaired items have a certification and a logo that identifies them, and that for this reason their cost is lower without this indicating lower quality. with regard to recycling, it must be taken into account that the organization of this sector of society dedicated to collection is in process, employers can adopt some workers of this trade who work in their environment and provide them with endowment every six months and make them aware of how important their work is for society, the environment and the economy of the country, when their work is dignified, will not feel like a relegated social class of little value, they can even become multipliers in their area of work of the benefits of a correct classification of solid waste. for the cotec foundation (2017), the transition from the linear to the circular economic model can create numerous jobs and promote socio-economic growth at the local level and strengthen social cohesion and integration. by investing less in raw materials, workers' working conditions can be improved. discussion the circular economy as an economic model must be recognized for its social, economic and environmental contribution, therefore companies must adopt as a strategy a leadership focused on the sustainability of the ec, although it is true that the government must do its part, that is, create policies that support the development of the circular economy, companies must concentrate on strategies that allow the transition from the linear model to the circular from their economic activity, the results of these efforts will only be fruitful if there is a reciprocal relationship that feeds both sectors; therefore, the strategies implemented in the public sector should not only have regulations as a preference, but these should be aimed at facilitating access to financial support and financing of projects focused on the creation of innovative technology useful for companies in all sectors including those responsible for solid waste collection. (discussion) taking into account that the deterioration of the planet is not diminisheddue to the fact that there are still inappropriate practices in human beings and an economic model that prevails despite the efforts, it becomes mandatory that at the local and global level the strategies aimed at making the circular economy model mandatory and not remain only in the discourse http://www.jescae.com/ global sustainability research www.jescae.com 7 table 5. types of strategies to empower e.c. pedagogic technological social • the clarity of the circular economy allows company directors to transmit the concept of ec to their employees and other actors related to the company, (eulac foundation 2018). • strong investments and continuous education of citizens on the issue of the use of waste. sáez and urdaneta, (2014) • the schools allow pilot tests, in addition, the actors involved are repeaters of the knowledge within their environment regarding solid waste management. romero, (2017). • raise consumer awareness about the large number of impacts generated by the textile industry, by the abandonment of a garment, its decomposition time, the amount of dyes and microplastics generated as a result of its decomposition. peña a (2019) • iinnovate in new technologies, processes, services and business models cotec, (2017).. • designmachines to make it easier to disassemble and separate each of the parts and materials that make up a product to be reused, remanufactured or recycled • support of the orange economy to the circular economy through projects that focus on innovative technology. • there are systems that recognize the people who recycle, the type of waste, systems that warn when the containers are filled and these automatically compact the garbage, specialized systems for people with disabilities, machines that give money in exchange for materials that are recycled and luminous screens that inform the user about the classification of waste. caf (2018) • the fight against obsolescence, issues such as increasing the coverage of guarantees, the establishment of minimum useful lives, or informing the consumer about the shelf life of each product are supported by the new legislation as lines of fight against obsolescence. express spanish technical institute of cleaning (2017), • require repaired and refurbished items, a certification and a logo that identifies them, and that for this reason their cost is lower without this indicating lower quality. • educational strategies and waste characterization improve the generation of economic income for people dedicated to recycling by applying a more comprehensive recycling. soria, (2016) • we must produce a better human resource, because if we do not use this resource, we will not move forward. you have to focus on people, on training" walter stahel. • investing less in raw materials improves workers' working conditions. colombia is one of the leading countries in the region that is concerned with showing and promoting an interest for the transition to the circular economy, however, there are different limitations, currently both consumers and companies maintain a relationship of consumption and production focused on the linear economy model (produce, consume and discard), privileging factors such as price over quality and useful life of products, (castle 2018). it must be recognized that in colombia people are not yet prepared for certain behaviors driven by cd and their absence can be considered as an obstacle that slows down the transition from the linear to the circular. in europe there are businesses dedicated to the purchase and sale of second-hand clothes, however, the pride of the vast majority of colombians is to buy an item made supposedly with virgin raw material since they consider it important to be the first owner and that will guarantee the durability of the article unlike a remanufactured or second-hand product. although the circular economy is often associated with recycling, this is not the only way to contribute to the sustainable development goals (sdgs), other ways to contribute to these objectives is the creation of companies whose purpose is the ec, to achieve this end companies must focus on the design of innovative products that can be reused, repaired, remanufactured or recycled, these strategies allow them to be more competitive by reducing investment in virgin raw materials. although the design strategy contributes indisputably from the economic and environmental, ramos (2019) highlights that by proposing the elaboration of tableware from banana leaves as an alternative to plastic sheets, it is much easier to adopt the circular model when new products are produced because existing ones such as plastic tableware make it difficult to change. "consumer demand is a crucial component to the success of product design strategies and at any given time can become a barrier to design strategies for ec." (re yes forero, i. a. 2021, p 68). although the circular economy model has been globally accepted as the appropriate economic model to achieve the fulfillment of the 2030 agenda for sustainable development adopted by the un general assembly, this implies that in the transition process the way of producing and a global http://www.jescae.com/ global sustainability research www.jescae.com 8 awareness of environmental damage must be changed, social and economic generated by the old model of linear economy, it is precisely in these aspects where the different sectors of society must have a clear knowledge, it is well known that many entrepreneurs do not dare to make the leap to have their companies organized with the old form of linear production, change implies investment, time and pedagogy to raise awareness among its managers and staff in general. if it is a question of achieving the goal that by 2030 colombia will be among the top three most competitive economies in latin america, we must not lose sight of the situation that collectors or recyclers are going through. it is said that cardboard among solid waste is one of the most important for its contribution to the environment, however, this is only the opinion of those who do not exercise this activity and are unaware of the social problems that recyclers or recuperators go through, they ensure that there is no collaboration of society in general with respect to the final disposal of cardboard and other waste, from the economic some say that the collection of cardboard is not profitable due to its volume and its low price, to this is added that there are seasons that greatly lower the value and the response with which they find is that they are not buying. with regard to deposits, little infrastructure and little technology can be appreciated, however, recycling is still the solution of many desperate unemployed who seek sustenance in this way. although recycling and reuse are activities that man has practiced since he lives in community, its objective was not to reduce the deterioration of the environment, the reason was and is to survive, to be able to satisfybasic needs. taking into account the above, colombia like other countries is aware that the reduction of pollution generated by solid waste, especially single-use plastics, is one of the great environmental challenges that is intended to be solved with the implementation of the circular economy model, however, with the appearance of covid-19 these have become a safe protection option worldwide for the security they provide and their low cost. personal protective equipment such as masks, plastic packaging and other sanitary waste generated for protection reasons, require measures to be taken with respect to collection management practices in order to positively impact health and the environment. according to plastics technology mexico (2020) in its article reflections on covid-19 and residual plastics written by chemical engineer adrián méndez prieto, it is recognized that, although before the pandemic single-use plastics were strongly pointed out, the health sector and governments found the solution to reduce infections and deaths in single-use plastics used in personal protective equipment (ppe) for being reliable and accessible. un environment executive director erik solheim in the foreword to the un report single-use plastics: a roadmap for sustainability (2018), states that plastic is not the problem, the responsibility for what is done with it is ours in terms of how to use it, plastic has facilitated the expansion of solar panels, clean energy from turbines, food storage and in the health sector the use of plastic has saved many lives. the united nations reports in un news global look human stories of march 30, 2021 that the use of plastic during the covid-19 pandemic affects the most vulnerable because the disproportionate increase in plastic from 2020 to date is worrying since not being able to be recycled all single-use plastic would increase environmental pollution. according to the united nations, more than 70% of this plastic will end up in the ocean and landfills, and up to 12% will be burned. it should not be overlooked that companies dedicated to the manufacture of plastics prioritize the cost of the raw material, therefore, if oil prices are low, virgin resins end up being preferred because they are of lower value with respect to recycled ones. thus, plastic pollution increases due to the new incursion of new packaging and articles made with virgin resins, in this situation it seems that efforts aimed at protecting the environment and empowering the circular economic model were at a slower pace than environmental deterioration. with the presence of the pandemic, the little preparation in which the waste recovery system is found in health services, restaurants and other places that depend on single-use plastics to carry out their activities safely is demonstrated, as well as the scarce protection and preparation of recyclers to carry out their work without exposing their health. from sánchez's perspective in his article "the postpandemic challenges in solid waste management" he expresses: while the rapid disposal of single-use products is often seen as beneficial to the health of staff and consumers, the imminent increase in the volume of this waste resulting from the covid-19 pandemic challenges to overwhelm existing waste management systems that have not been able to cope with existing plastic waste satisfactorily. pag (6) conclusions the promotion of the circular economy must occur in all social spheres and in all business activities to change the linear paradigm that prevails in the country, in this process the private sector, the public and citizens in general must participate, being thus, the change of mentality is fundamental for the success of the transition process from the linear to the circular economy. it must be recognized that ecodesign, the implementation of innovative technology and access to loans for circular http://www.jescae.com/ global sustainability research www.jescae.com 9 activities are fundamental for the development of the model, in addition the successful experiences of developed countries in the field of cd can be replicated since they offer the opportunity to improve through pedagogical, technological and social strategies. the implementation of innovative technology is essential to achieve sustainability, therefore, the government must support the creation of companies that intend to operate with this economic model, resources must also be provided to those companies dedicated to the collection of solid waste to invest in equipment that allows them to be more efficient, in this way they ensure their economic sustainability, contribute to environmental and social sustainability, likewise citizens must be trained, aware of the importance of proper management of solid waste and companies must take responsibility for their waste, extended producer responsibility is fundamental to the success of the ec. although one of the objectives at a global level is to reduce the use of single-use plastic, it is pertinent to recognize that with the presence of the pandemic its effectiveness in minimizing the proliferation of this is indisputable, the contribution of these plastics forces to recognize the importance of their permanence in sectors such as health and food, therefore, plastic is not the problem as erik solheim puts it, the problem remains the same since before the pandemic. colombia, like other countries concerned about the consequences generated by the linear economic model, has become aware that it must generate strategies aimed at transition. resolution 1407 and the dane reports allow the country to have clarity on the shortcomings and strengthens in the field of cd, however, the problem generated by the pandemic at a global level also tested the management of solid waste by becoming evident weaknesses in the collection systems, increasing the impact on ecosystems, affecting the fulfillment of the goals in terms of packaging. however, it is pertinent to bear in mind that the responsibility for keeping circular economy strategies on the right track should not only fall on the state, the planet belongs to everyone and everyone is responsible. references arroyó, f.

nigeria ogundeji peter ayobami*1, gabriel fadairo1, ogundeji bolarinwa2, ekundayo julius2 1department of architecture, federal university of tech., akure, ondo state, nigeria 2university of medical sciences, ondo, ondo state, nigeria corresponding author: ogundeji peter ayobami; peter.ayobami.pa@gmail.com received: 09 december, 2022, accepted: 23 december, 2022, published: 24 december, 2022 abstract natural occurrence of streams, rivers and flowing water attract emergence of urban housing along river bank is to tap water for domestic, irrigation, industrial use; deposition of minerals and nutrients for agricultural purpose. consequences caused by recent events of floods in the urban centers are not limited to socio-economic, environmental loss but also increase in health challenges with loss of life. flood itself cannot be held responsible for the catastrophe but the activities of people, society and urban housing encroaching on natural space of lowland, wetland, prone areas, also; landscape reshape to reclaim beaches by cutting off hills fosters thereafter, destruction of life and property. the study therefore identified the consequences of urban housing flood in three areas. quantitative method including frequency tables, histograms, pairwise ranking, chi-square and analysis of variance (anova) were also used to interpret the data collected. the result shows that disease occurrence is significant to urban housing flood; correlation between flood and marginalization to adequate housing quality; and floods is significant to urban housing development. it is clear that vulnerable and flooded prone milieu is mostly occupied by urban poor because of inability to avoid good housing quality and there is high of cases of cholera, malarial, water-borne, measles among residents in the study area. society is becoming more aware that floods can be controlled to a limited extent; hence, safety against floods must be sought for, to prevent loss of life, properties and socio-economic investment. this paper recommends absolute delineation from vulnerable area, government and property developers should ensure good housing quality, total relocation of urban housing from marginal land and compensation to victims. studies on comparative evaluation of urban housing vulnerability to flood on highland and lowland; environmental disruption of urban housing in lowland require additional investigation. keywords: health performance; safety; vulnerable milieu; urban housing floods; disasters; diseases introduction natural disasters have caused significant damages to both natural and man-made milieu in recent times. hence, such hazards are caused majorly by natural forces which include earthquake, tsunami, tornado, landslide, wave and greenhouse effect, land submergence, typhoons/hurricanes/willy-willies, smog and among others (ogunbodede and sunmola, 2014). not only but also flood which is surface water covering a previously dry area. flood is a destructive water-related hazard and is mainly responsible for the loss of human lives, infrastructure damages and economic losses (ogunbodede and sunmola, 2014; ogundeji and fadairo, 2018; fadairo and ganiyi, 2012). urban flooding generation is caused by natural multifactorial mechanisms such as geomorphological (the formation and structure of the earth surface such as texture and type of soil, rock), physiographic (the natural features of the earth's surface such as topography) and climatic conditions (rainfall, humidity, precipitation) all affecting the hydrological (the properties, distribution, use, and circulation of the water on earth and in the atmosphere) processes, the generation of floods and in addition to negative impact of urbanization growth in recent time (fadairo, 2013; basorun and fadairo, 2012; amao, f. l., 2012; ogundeji and fadairo, 2018; onibokun, 1972). recently, there are numerous studies on mitigation to flood damage due to record of an increase in its frequency, magnitude, and intensity (douglas et al., 2010; pitt, 2008). mailto:peter.ayobami.pa@gmail.com global sustainability research global scientific research 43 also, studies have shown that natural causes of flood can only be reduced to minimal effect in as much as rainfall, coastal, low land or flooded prone area and other natural element would be difficult to adjure. aside the natural sources of flooding such as heavy, prolonged rainfalls and bank overflows, there are anthropogenic (relating to or resulting from the influence of humans on the natural world) causal factors of flooding (taiwo, o. j., agbola, b. s., ajayi, o. and wahab, b. w., 2012). this paper investigates the inevitable existences of lowland areas within the urban centres and health associated prevalent diseases. aside intense rainfall events that generate flash floods, the man made effect and activities on the earth surface such as tillage and deforestation in the rural, also increase’s in concrete constructions and pavements in the urban centres. it is a clear statement that vulnerable and flooded prone milieu is mostly occupied by urban poor because of inability to avoid good housing quality, the study area shows that the features of prescience had made the occupier to abandoned and relocated to high or nonprone area. at a time, dwellings were typically constructed on higher land, while lower grounds were used for farming. riparian peoples benefited from floods sediment which enriched the soil with nutrient and irrigation for agriculture. hence, people lived in harmony with floods (kundzewicz et al., 2014) in the past. the frequency and consequences of extreme flood events have increased worldwide. the key impetus for these increase are the world’s population growth, the increase in socioeconomic activities in floodprone areas and significant climate change, which occurred in almost all countries of the world (ogundeji &fadairo, 2018; bouwer et al., 2017). on the other hand, the steady growth of impervious surfaces and reduction of forestation increases floods. moreover, the exponential increase in development, expansion of urban areas to nearby rivers and encroachment to river path or prone area exacerbate flooding and simultaneously increases the impact (nardi, f., annis, a., biscarini, c., 2018; samela, c., albano, r., sole, a. and manfreda, s., 2018). therefore, there is a need for strategic applications basically to “control human influences on floods occurrence” and also to evaluate the impact of such events. hence, the research area is the human influences which are construction of housing and its subordinate amenities which covered suppose forested land usually through which amount of water percolate is disavowed in the urban centers. the accumulation of this water together with the sewage from these homes becomes a treat that yield to flooding. the activities of man on the natural surface that are attributed to flooding includes roofs, pavements, roads, concrete works, bridge constructions, dams, wastes, sidewalks, parking lots (kundzewicz, 2004), extensive asphalted or concrete landscape, drainage, coastal or river path backfilling (beach reclaiming), irrigations and or rechanneling of river path, urban housing and building construction are among other influences. statement of problems flooding has become a common feature in nigeria not only in the low-lying coastal areas but also in the hinterland as well as the wetland regions (ogunbodede and sunmola, 2014). the population growth and urbanization activities have exerted pressure on available marginal and flood prone lands to the extent that a larger proportion of lowland and river basins have been encroached by people (ogundeji and fadairo, 2018). these activities on such encroachment include housing and its adjoining amenities which include poor drainage system, pavement that reduces infiltration, discriminative refuse disposal and with blockage of water path. the results of such man influence amount to surface water and floods effect. water is universal solvent. hence, floods deteriorate if not damage both man-made (bridge, roads, houses and other urban structures) and natural structures (loose soil, contaminate drinking water, destroy greenery). man also extend marginal milieu to usable territories, ogunbodede and sunmola (2014) explain that urbanites reshaped both natural and cultural landscapes by leveling off hilly areas to fill valleys, reclaiming beaches, wetlands and hinterland (a case study of leki community in lagos, nigeria) into usable business ventures; thus, making large areas of artificial land in the urban environment and simultaneously with erection of different magnitude of urban structures occupying this new land irrespective of whether such lands have the capacity to retard inflow of water or not. aside recorded economic impact, oriola (2000) and sewel (1969) also confirmed the environmental damage induced by man’s exploitation. research question from the foregoing objectives, these research questions are pertinent: 1. what are the causes of urban housing flood in the area? 2. is marginalization to adequate housing quality also contributed to urban housing flood? 3. does impervious feature of urban housing have effect on flood intensity and magnitude? 4. what are prevalent illness experiences by the respondents in urban housing flood milieu? aim this paper aim at identifying health effect with level of productivity against urban housing floods in the lowland of odosida in ondo city. global sustainability research global scientific research 44 objectives the specific objectives are to; i. examine the general causes of urban housing flood in odosida area. ii. assess lowland (prone) area within the urban centres and its vulnerability to floods iii. evaluate the increase in development, expansion of urban areas and other anthropogenic (activity of man) factors and its significance to excessive floods. iv. evaluate effect of floods on human health. research hypothesis in line with the research question 3 and 4 of this work, the following hypotheses are postulated: h0: disastrous flood is significant to urban housing development h1: flood disastrous is not significant to urban housing development h0: the average diseases occurrence (mean) is the same. that is, the disease occurrence is significant to urban housing flood within the study area. h1: the average diseases occurrence (mean) is not the same. that is, the disease occurrence is not significant to urban housing flood within the study area. background to the study urbanization is basically continued growth of urban centre, swelling and increase in population concentration in the city (bakare, 2017). urbanization is fast impacting its negative consequences on most of the cities as a result of rapid urban development/land use change in the form of massive road/building construction, removal of soil surface for infrastructure purposes, drainage/canal construction, deforestation and soil surface pavement (ogundeji and fadiro, 2018), altogether have increased the runoff in addition to rainfall and snowmelt, thereby increases the risk of flooding in the cities (usgs, 2011; nirupama and simonovic, 2006). as urban population comes to represent the larger proportion of the world population likewise urban floods will account for an increasing part of total flood impact (jha, robin and jessica, 2012), hence the urgent need to examine the circumstances surrounding flood disaster cannot be over-emphasized. bakare (2017) explained that devastating urban areas, unplanned development in floodplains, ageing drainage infrastructure, increased paving of soil surface and other impermeable surfaces, with lack of flood risk reduction activities contribute to flood disaster impacts (jha, et al, 2012). housing quality in the survey area lowland area in odosida is experiencing poor housing quality, deplorable basic facilities, high level of housing deterioration, as well as growing incidence of slum due to an increase in surface water for long period of time. the dwellers built home not only on the high land but also on the available low land as a result of urban expansion without a fore knowledge of the future treat. the study shows that low-income earners are the dominant and house owner of the environment. most of the occupants narrated that the land were allocated to them in the period of dry season and only to discovered that the land is at the receiving end for surface and running water from the whole odosida community. housing problems in nigeria developing countries are characterized with an uncontrollable growth of the urban population often caused by lack or poor infrastructural amenities and poor economic conditions in the rural areas has opined by ogundeji and fadiro (2018). the proportion of the nigerian population dwelling in urban centres has increased from 7% in 1930s, 10% in 1950, 20% in 1970, and 27% in 1980 to 35% in 1990 (okupe, 2002). there is occurrence of overcrowding on existing housing, ruralurban drift that has caused squatter settlements in cities with 60% of nigerians houseless (ogundeji and fadiro, 2018; olayiwola, 2012; federal government of nigeria, 2004). majority of the houses is also constructed with second-hand materials, build on illegal land (adeyeni, 2015), marginal or flood prone area (ogundeji and fadiro, 2018). they are badly maintained and lack the basic necessities of life like sanitary facilities, light, air and privacy (agbola, 1998). researchers on housing studies conclude that urban centres in the country are characterized by high-density buildings, sanitary problems, air pollution, surface water, noise and solid wastes (filani, 1987; agbola, 1998). olotuah (2002) estimate 2.3 million urban dwelling units to be substandard, 33% of urban houses considered to be physically sound while 44% and 19% require minor and major repairs respectively to bring them to normative. thomas (2017) specifically discusses housing problems in nigeria under the following sub-headings; housing finance problem, low housing investment, high cost of houses and rent, inadequate access to buildable land, mismatch in housing goal and real achievement, and building materials problems. housing finance problem nubi (2008) narrates the popular method of housing finances in nigeria which are through personal savings, loans from friends, relatives, commercial banks and other mortgage institution. these sources are no longer assuring and sustainable especially global sustainability research global scientific research 45 for the low income earners and the inflation rate in nigeria (agbola, 1998) for procurement of land, material, wages and building services bills. low housing investments -according to the 1996 nigerian national report of the habitat ii conference, the level of housing investment as a proportion of gdp in ibadan and kano was low as 5.9% and 28.41% respectively and resulted from housing being a long-term low profit yielding investment when compared to other short-term fast profit such as manufacturing and transport (agbola, 1998). in addition, limited access with highinterest rates on housing loan partly characterized the problem of low investment in nigeria (olayiwola, 2012). high costs of houses and rent the combined problems of finance, rising costs of building materials and low housing investment have brought about housing shortages. for instance, the unit price of a three-bedroom bungalow (bakasi type) built by the federal housing authority in abuja increased from #l.65 million in 1998 to about #3.5million in the year 2003 and about 10.8million in year 2012 (thomas, 2017). inadequate access to buildable land lands in prime locations in the urban centres are beyond the reach of low and medium income households in nigeria (thomas, 2017) prior to the promulgation of the land use decree no.33 of 1978 where land allocation was vested in the governor or the local government chairman (okupe, 2002) compare to adeleye (2012) enunciation on traditional land tenure system which was with ease. mismatch in housing goal and real achievement thomas (2017) opined one major problem of adequate housing in nigeria is the mismatch between housing goal and real achievement which were marred by low pace of construction, high costs of building materials, budgetary shortfalls, poor coordination, use of unrealistic standards and problems of land acquisition. building material problem olotuah (2006) explained the efforts to boost local production by the nigerian building and road research institute (nbrri) established in 1978 for that purpose has not achieved much. the high cost of foreign building materials is one of the major problems militating against adequate housing supply (onibokun, 1986; agbola and onibokun, 1990; agbola, 1993; 1998). characteristics of coastal areas housing their local topography limited the amount of land suitable for development and as such put land prices at a premium (mclean and shen, 2006). physical isolation of wetland, lowland and coastal towns has been often a significant barrier to economic growth, development and regeneration (thontteh, 2014). however, complete relocation could be the best solution as regeneration would not be enough to reduce effect of flooding. floods growth and its effect floods are the most common natural disasters and represent 40% of all natural disasters between years 19852009 (soukopová and furová, 2012). also, kundzewicz (2004) affirmed that floods have killed annually on average more than 12,700 people worldwide, affected 60 million others and caused 3.2 million people to become homeless (kundzewicz, 2004). unicef (2022) acknowledged that since september 2022, worst floods in a decade affected 2.8 million people of which an estimated 60 percent are children across 34 of the 36 states in nigeria with over 1.3 million and 600 people displaced and have died respectively in relation to flooding. thus, increases the attention of researchers to the consequences of floods and measures that could be developed to reduce economic effects (loss) of flood (munich, 2005). studies explained that flood-prone areas were initially attractive for socioeconomic activities through provision of water resources for domestic purpose, irrigation, industrial use, minerals and nutrients for agricultural production which also encourages urban development (smith and ward, 1998). increasingly number of housing in the urban vulnerable centers also increases the number of casualties. aside the deduced socio-economic losses by many researchers (ogundeji and fadairo, 2018), there is need to put an end to poor health and loss of lives which cannot be quantified. bangladesh and china have recorded at least 2,5 million fatalities in the last 100 years in major floods which has drastically reduces human production and inversely reduces the economic output of a country. the nature cannot be held responsible for floods and it harmful effect, but the people, society and the urban housing taken natural space from water and put themselves in her way (mžp sr, 2010). the flood as a natural hazard has effect on the stability of society. if more urban housing, society and people are to dwell in vulnerable areas with more businesses to settle down in these areas, then the more intensive effect a flood event will have upon society (seifert, 2012). damage to infrastructural lifelines in the community includes water supply, sewerage and drainage, gas and power supply, telecommunication, roads and railways. hospitals, schools and fire brigades are essential facilities that got damage too. however, direct damage (costs for repair, replacement of damage facilities, equipment) and indirect damage (loss of revenue by the network operator, delay costs) to the affected structures are the reciprocal loss. (dutta et al., 2003; scawthron et al., 2006). global sustainability research global scientific research 46 background information about the study area the physical geography of the area, apart from communities located in the upland are plain, all other communities fall within the lowland because of its proximity to core business district (cbd) and its economic advantages. the lowland consists of rivers, creeks, estuaries and stagnant swamp covers. the region falls within the 'tropical wet and dry climate which range between march and october and dry season comes between november and february respectively with mean annual rainfall of about 1615mm. the annual mean temperature is 27°c, with a maximum of 30°c. ondo town is the most populated city in ondo state after akure and with 113,900 during the 1991 population census, located on latitude 06°30'n and longitude 04°45'e. the town is bounded on the north by ile-oluji/okeigbo local government area and on the east by idanre local government area why on the south-west is odigbo local government area (ogundeji and fadairo, 2018). identification of three different points after reconnaissance survey of odosida area that are lowland are flooded, often resulted to disruption of transportation, communication, structural damage to buildings and loss of lives and properties. research methodology purposive sampling method was used to sample three areas namely adeyemi college of education (ace), christ apostolic church (cac, oke-iye) and university of medical science (unimed campus) of odosida community in ondo city for information collection. they were wetland and lowland regions that are vulnerable to flooding. administration of questionnaire to residents to deduct their socio-economic profile, sex, age, distribution, nature of the environment, waste disposal methods in the environment, causes of flood in the milieu, consequences of flood particularly reference to health challenges and solutions to floods in the environment. the interview was successful because of the help from the community chairman and the youth leader in the area. a total of one hundred and fifty (150) respondents were interviewed from the study area. data collected were summarized and stored in statistical tables and charts. these also include frequency distribution tables and histogram. relevant mathematical and statistical techniques were used where appropriate for the analysis. results and discussions the physical environment suffers destruction of vegetation, washing away of top soil and water pollution, displacement of wildlife from their natural habitat due to activities that accompany urbanization in the recent times. one of this activities of urbanization is construction of housing and it amenities that has disrupted the natural surface of the earth crust through excavation, removal of surface soil, diversion of river path, filling up of beach, lowland and lagoon. the aftermath of such activities among others aided the magnitude, intensity and rate of water that ought to have found its way through natural means of “percolation, waterlogged and runoff” but interrupted. hence, rapid urbanization increases number of roof, housing and pavement in the urban center and thereafter reduces rate or amount of water to be percolated. also, an encroachment of structures in waterlogged area and obstruction of water runoff path amount to flooding. fishing, irrigation, deposit of fertile soil for agriculture are among the positive effect associated with urban housing flood and the negative impact include dampness, destruction of properties, lives and land use changes which invariably affect socio-economic, health and environmental dilapidation respectively as a result of alterations to the natural environment. socio-economic characteristics of respondents the following indicators; income, health, education, occupation and buildings condition were considered to ascertain level of effect of urban housing floods in the environment. table 1 and figure 1 shows 62% males and 38% females were interviewed thus; majority respondents are male over female which is a reflection of female marginalization to access housing facility and legal land (bako, 2012). this experience is a violation of human right and contributes to women’s increasing poverty (unchs, 1985). table 1: sex distribution of the respondents sex opp. ace cac okeiye unimed campus total (%) male 30 37 26 93 62 female 20 13 24 57 38 total 50 50 50 150 100 source, author’s archive figure 1: sex distributions of respondents source: author’s archive the age distribution of the respondents shows that large number of population comprises youth ranging from;

so therefore, the null hypothesis cannot be rejected if calculated value is less than the table value. in other words, there appear to be a significant association between the two variables: flood damages effect is significant to increasing numbers of urban housing. general physical condition of the respondents the general condition of the body, especially in terms of presence or absence of illnesses, injuries, or impairments of the respondents is explain in table 6, the common ailments and disease experience by people. malaria is the most infectious disease caused by parasite that can be transmitted by the bite of infected mosquitoes, very common in the tropical, characterized by recurring chills and fever. other diseases associated with flooding include catarrh, cold, diarrhea, skin disease, typhoid, dysentery respectively. aside the level of poverty, health challenge contributed to poor production of the urban economic value and loss of lives. table 8 indicates the pair-wise ranking tools showing most prevalent diseases in hierarchical strength. there could be generally high increase in number of cases of cholera, malarial, waterborne related, measles among residents in the study area. prevalent disease within the study area is significant to urban housing floods. this is clearly shown in the analysis of variance (anova) presented in table 7. table 6: common diseases within the study area diseases opp. ace cac okeiye unimed campus total skin disease 6 8 7 21 dysentery 5 8 5 18 diarrhea 10 9 11 30 catarrh 15 11 13 39 asthma 2 3 4 9 cold 12 9 13 34 tuberculosis 4 7 6 17 typhoid fever 6 6 7 19 malaria 17 16 18 51 total 77 77 84 238 source, author’s archive table 7: variance ratio to test significance of mean square treatment source of variation df ss ms f treatment on disease 2 3.630 1.815 0.088 error 24 492.444 20.519 total 26 496.074 source: author’s archive where;

plants, livestock and properties damage; houses, sheds, electricity) and consequently a health catastrophe in odosida. recommendations it was discovered that poor economic and income value has an influence on housing quality. this problem are to be solved majorly by the government through housing provision, government acquisition of land, provision of better income opportunity, incentive or relive materials to the affected flooded area among others. the anova table also shows that there is significant relationship between illness and flooding in the study area with serious adverse effects on environment and the health of city residents. hence, total relocation of urban housing from vulnerable or prone area especially environment characterized with lowland and other delineated area by government for the purpose of safety of life. it is noted that reduction of flood impact is not enough for life safety. hence, lifes has worth more than wealth (multiple properties) and demand relocation to high ground. the land use act of 1978 which entrusted all land into the hand of governor of states in nigeria has also, automatically added to their responsibility the diligent to study the landmass in compass, to mark out, delineate or restrict urban dwellers from occupying marginal, vulnerable and prone area within the urban centers. urban housing flood education is essential, to increase individual interest and awareness of general information on flooding and mitigation devices. society should have access to weather forecast, news, lowland or vulnerable restricted environment peradventure through different form of publicity. absolute control of floods is impossible but partial control through “flood prevention, flood reduction and flood protection”. therefore, flood protection includes construction of flood walls, dykes (flood embankment), dams and reservoirs to control flood and minimize it effect by regulating its flow or diverting it away from where it could damage properties (oriola, 2000). findings also shows that high proportions of urban dwellers dispose refuse into gutters and other natural water path especially when it is raining. thus, aggravates flooding. hence, appropriate mode of wastes disposal by public or government refuse collector should be encouraged. free movement of water on channels will reduce flood occurrence during rainy season. the river valley, channels as well as gutters should be properly monitored during rainy seasons to avoid blockages. set-back laws must be enforced by planning authorities and related agencies for all structures close to the rivers, valley and lowland in urban areas. a set back to streams for any structure is 30 meters and in a specified cases above 30 meters (ogunbodede and sunmola, 2014). aside roofs of urban houses, the pavement, interlocking, concrete, asphalt on road and no room for landscape reduces rainfall percolation. this resulted water is added to surface run-off and flood the environment without adequate channel or drainage. thus, a reduction in concretized surface of urban environment will reduce flood in the urban housing area as more of the surface run off will percolate to join underground water. conclusion urban housing flood disaster is one of the environmental problems in nigeria, the impact got aggravated because of people, society and urban housing activities (ogunbodede and sunmola, 2014). the havoc in returns did not only include economic loss but also “health challenges and consequentially loss of life”. it is therefore a need for man global sustainability research global scientific research 50 and urban housing activities to be harmonized in relationship to the environment so as to reduce flood and its effects on life which is more important to properties. it is a clear statement that vulnerable and flooded prone milieu is mostly occupied by urban poor because of inability to access quality housing. there could be generally increasingly cases of cholera, malarial, measles and water-borne diseases among residents in the study area if flood persist thus, among other recommendations, total relocation of urban housing from vulnerable or prone area especially environment characterized with lowland and other delineated area by government for the purpose of safety of life to higher ground. researchers’ mitigations to the impact of flood would be adequate if in addition, total relocation of urban activities from prone, marginal and vulnerable area. thereafter, there would be guarantee of safety of life and properties. furthermore studies on comparative evaluation of urban housing vulnerability to flood on highland and lowland, environmental disruption of urban housing and also, urban housing poor telecommunication challenge on lowland will contribute to knowledge through additional investigation. conclusively, result shows that there is correlation between flood; and marginalization to adequate housing quality, urban housing and disease occurrence within the study area. acknowledgment: none funding: none conflict of interest: none references action aid, (2006): climate change, urban flooding and the rights of the urban poor in africa. key findings from six african cities, a report by action aid, october, london and johannesburg adebowale, k.o., agunbiade, f.o., olu-owolabi b. i.

2023, accepted: 28 april, 2023, published: 30 april, 2023 abstract the defective environmental changes caused by climate change have a drastic harmful effect on natural habitats and species. this is concerning the fact that there are signs that the increase in the intensity of temperature often has (caused by human activities) an effect on biodiversity. however, the threat posed by climate change to biodiversity is expected to increase, given the harmful human activities. the scientist has identified that if the present rates of global warming continue by 2030, it will result in a significant detrimental impact on biodiversity. in this regard, this study adopts a doctrinal method of study in examining the current causes of climate change, the effect of climate change on biodiversity, and several global legal frameworks concerning the preservation and conservation of biodiversity. the study also detailed the lacuna inherent in the conservation and preservation of biodiversity, and possible legal and scientific method for revamping biodiversity. the study further concluded and recommended that adopting this possible solution it will curtail harmful human activities that often cause climate change that negatively affect biodiversity. keywords: climatic change; biodiversity; legal; framework; environmental introduction preservation and conservation of biodiversity are fundamental for the sustainable relationship between man and it environment. the uniqueness of this relationship is well articulated in various legal frameworks on biodiversity conservation. various studies have shown that the well-being and economic prosperity of all people depend largely on man’s harmonious living with mother earth. that is because, we depend on the earth for our basic and non-basic needs for daily survival including food, medicine, recreation, water, air, security, etc. (united nations, 2022). given the vast benefits derived from the richness of the environment, it is only natural for stakeholders within and across state lines to form an alliance in other tackle the continued loss of biodiversity and the threat it poses to nature and human well-being. there is ample scientific evidence that biodiversity is fast dissipating at an unprecedented rate in human history (ipbes, 2019). in this regard, several global frameworks have been formulated and adopted to address this menace. starting from the rio earth summit of 1992 to the “kunming-montreal global biodiversity framework of 2022, all of which are aimed at arresting the ongoing loss of biodiversity. most conservation techniques take into consideration, science, economics, religion, and law. mailto:aidonojie.paul@edouniversity.edu.ng mailto:majekodunma.toyin@oouagoiwoye.edu.ng mailto:aidonojie.paul@edouniversity.edu.ng global sustainability research global scientific research 35 however, this study tends to focus on the legal aspect of biological conservation. before 1950, no legal attention was given to pollution and ecological issues (ukhurebor and aidonojie, 2021; aidonojie et al., 2020). this is concerning that before 1950, just a few bilateral and multilateral agreements tend to regulate international environmental issues (ijaiya et al, 2018; dzidzornu, 2004). most of the international agreements in the operation focused more on unrestrained and controlled national sovereignty over natural resources (aidonojie et al, 2022; riget et al. 2016). furthermore, these international environmental agreements also regulate ecological issues related to boundary waters, navigation, and the rights to fishing along shared waterways (aidonojie et al, 2022; ladychenko et al., 2020). in this regard, it suffices to state that no international legal framework concerning the conservation of climate earth and its biodiversity from any form of harmful human activities that may cause depletion of the ozone layer. in this regard, human activities that could be harmful to the environment were unchecked, leading to climate change, and drastically affecting the conservation of biodiversity. however, the incessant climate change and depletion of the ozone layer, resulting from global industrial stride and the indiscriminate exploitation of biodiversity, has led to the deterioration of climate earth biodiversity (cifci and oliver, 2018). in this regard, to curtail harmful human activities, several international laws from 1950 till date have been agreed upon and adopted by several nations that make up the international community to ensure the conservation and preservation of climate earth biodiversity from harmful human activities (charney, 1995). although, it suffices to state that introducing an international environmental legal framework concerning the preservation of climate earth and its biodiversity is one of the greatest achievements of the international community (megan et al. 2020; aidonojie, 2023; anani et al. 2022). however, it has been observed that although several international environmental legal frameworks tend to provide for the preservation and conservation of biodiversity. unfortunately, there is still a high rate of emission of methane (ch4), water vapour (h20), nitrous oxide (n20), and carbon dioxide (c02) as stipulated in the various international legal frameworks auta et al., 2017; aidonoie et al., 2022). furthermore, there has been a deterioration of biodiversity across the global environment resulting from harmful human activities. however, this continuous environmental hazard affecting biodiversity stems from the fact that most member states have a poor commitment to the agreement as it contains various international ecological legal frameworks (max et al, 2017). it is concerning the above that this study tends to embark on a study concerning the current trending of the causes of climate change and the effect of climate change on biodiversity. also, the study will also examine the legal framework as a panacea concerning the preservation and conservation of biodiversity. furthermore, the study will also identify the challenges inherent in the legal framework preservation and conservation of biodiversity and the way forward of revamping the legal framework concerning the preservation and conservation of biodiversity. literature review the term conservation may mean to carefully preserve and protect something from loss, decay, or destruction. in this context, it may be referred to as the official supervision of rivers, forests, and other natural resources in other to preserve and protect them through prudent management. conservation may also be considered as the act of protecting earth’s natural resources including air, water, soil, and wildlife in a manner that may be useful for present and future generations. this process may entail maintaining the diversity of species, genes, and ecosystems. the distinction between the term “conservation” and “preservation” is somewhat unclear as the use of these terms has varied over time. for convenience, some scholars, however, used them interchangeably this is because both terms are similar to the extent that they tend to achieve the goal of protecting biodiversity. however, technically speaking, conservation and preservation are different. this is evident from the method and technique they apply to achieve the same purpose. conservationist seeks to protect the environment through the responsible use of natural resources. on the other hand, preservation seeks to protect the environment from harmful human activities, at the extreme, preservation proposes the prohibition of man from using the environment as a remedy to extinction and climate change. it is unthinkable for humans not to use natural resources. the reason is that life on earth is sustainable through its usage. the goal of the relevant legal framework on biodiversity protection has been on global sustainability research global scientific research 36 conservation rather than preservation in its technical sense (santiago-avila, treves, & lynn, 2019). this is because with or without man’s intervention the loss, erosion, and extinction of biodiversity are inevitable. thus, a relevant strategy has been adaptation and mitigation. adaptation measures are necessary to curb the shortcoming of many stakeholders to curb their ghg emissions as required by various international, regional, and local legal frameworks (spier,2019). no meaningful discussion on conservation can be made without first recourse to rio de janeiro earth summit. rio summit laid down the foundation for global commitment toward environmental protection. it was at this event that world leaders under the auspices of the united nations formally made the needed commitment to the protection of the environment while pursuing economic development. a major feature or fallout of this event was the signing of the biodiversity treaty. rio summit suffered a setback because of the failure of member nations to make full commitments. especially, from the countries in the global north. again, it should be recalled that the requirement of member nations to take inventories of wild animals, plants, and all endangered species. the convention on biodiversity (cbd) at rio has been supplemented by cartagena, nagoya protocol as well as the recent kummin-montreal global biodiversity framework (gbf). according to steinhauser, et al (2022), the major thrust of this framework target is to reverse the loss of biological diversity, ensuring sustainable use of its component, and the fair and equitable sharing of benefits arising out of the utilization of genetic resources. the introduction of gbf is meant to strengthen and maintain balance in the protection of the environment through the integration of its objective with the provisions of the convention on biological diversity, the cartegena protocol on biosafety, and the nagoya protocol on access and benefit-sharing more efficiently and effectively. a major challenge in this framework may arise concerning the financial requirement of developing countries. as emphasized by rampheri, et, (2022) they stated that the challenge is that most developing countries do not have enough finances to tackle such issues, and many grappling with development needs so adequately face the required conservation needs. however, policymakers believe that protecting the human right to a clean, healthy, and sustainable environment, in line with the 1986 united nations declaration on the right to development is at the heart of full and better implementation. meanwhile, other scholars such as kanu (2022) posit that preservation of the environment is possible, through the conceptualization of nature as a mother, source of life, and nourisher. the concept of motherhood brings to bear other virtue such as respect, love, and care which may help in strengthening or promoting a good environment. in the case of nigeria, the most recent attempt to conserve the environment has been toward reducing the amount of carbon emission in the atmosphere through a national legislative framework for the mainstreaming of climate change actions. the act shows nigeria’s commitment to the global agenda of environmental sustainability. nigeria is also a signatory to the united nations framework convention on climate change (1992) and its associated kyoto protocol (1997). the country, following the agreement of cop26, has enacted the climate change act 2021. in summary, the act seeks to provide a framework for achieving low greenhouse emissions (ghg), inclusive green growth and sustainable economic development, and a climate-resilient society. one of the major goals of this enactment is to formulate programs for climate change mitigation and adaptation. in the world of environmental protection and sustainability, adaptation, and mitigation are complementary strategies, which virtually all nations within the global terrain (spier,2019). methodology given the rate of climate change and its effect on biodiversity, this study tends to examine the current impact and challenges of climate change on biodiversity and the various international regulatory frameworks concerning climate change and the preservation of biodiversity. in this regard, the study adopts or uses a doctrinal research method. the essence of adopting a doctrinal research method is to examine various primary international legal frameworks that regulate how man relates to his environment in curtailing the drastic effect of the harsh climate change. further, a doctrinal method was adopted or used to examine some international laws concerning the preservation and conservation of biodiversity. however, the doctrinal research method was also adopted in examining various scholarly literature in journal articles, online sources, and textbooks to enable the researcher to critically analyse and review the current trending and effect of climate change on biodiversity. the global sustainability research global scientific research 37 essence of the analysis of the scholarly literature is to reveal the fact that there is a need to revamp the various legal frameworks as a panacea in the conservation and preservation of biodiversity from the harsh effect of climatic change. result and discussion current trending of the causes of climate change the consensus among scientists and researchers is that climate change is caused by the emission of greenhouse gases (ghg) such as water vapour (h20), methane (ch4), carbon dioxide (c02), and nitrous oxide (n20) into the atmosphere (zahir, et al. 2021; aidonojie et al., 2022). these gases can absorb ultraviolet radiation coming to the earth from the solar system, which ordinarily ought to exit outer space but is trapped in the atmosphere. a high concentration of these gases in the atmosphere triggers the problem of global warming (known as the greenhouse effect.) anthropogenic activities and natural factors have been identified as the two driving contributors (forcings) to ghg emissions. unfortunately, a significant amount of the gases has been released daily by human-related activities since industrial development (kamshat et al., 2020). according to ahad et al. (2017), the release of ghg by human activities is partly responsible for the increase in the global atmospheric temperature since the mid-20th century. global warming is the factual expression of climate change due to too much concentration of ghg in the atmosphere. greenhouse gases usually act as a blanket or shield trapping heat generated from fossil fuel combustion within the earth, thus, preventing the release of these harmful gases into space, leading to an abnormal rise in the heat level in the earth. fabio et al. (2021) noted that c02 and ch4 play the most active role in global warming. however, alejandro et al., (2017) in their study, observe that co2 alone contributes about 75% of the total greenhouse gases released worldwide. a similar review of atmospheric activities between 1970-2010 reveals that c02 by anthropogenic processes contributed approximately 78% of the total greenhouse gases. reports by several agencies such as the america chemical society (acs), the america association for the advancement of science (aaas), and other empirical research published in scientific journals reveal that anthropogenic activities such as the burning of fossil fuel (e.g., gas, and coal.), deforestation for farming purposes, and other agricultural related activities, play a key role in the total emission of greenhouse gases. in their study, humans’ quest for civilization and economic prosperity contributes significantly to ghg emissions into the atmosphere. the acs, while acknowledging human influence on the changing world climate weather condition, noted that the change in earth's weather conditions is a direct response to the ever-increasing concentration of greenhouse gases in the atmosphere introduced by man with negative implications for the ecosystem (andrii et al., 2019; majekudumi et al., 2022). similarly, the intergovernmental panel assessment report on climate change (ipcc) under the sponsorship of the united nations, after a period of assessment and evaluation of scientific literature, came to the same conclusion in its fifth assessment report (ar5). ipcc is a team of an expert on climate issues drawn from all over the world by the united nations to provide a scientific explanation of the ongoing change in the global weather condition, to identify its potential consequences to the environment and the socioeconomic activities of humans to proffer a scientific solution(mitigation) through the adoption of policies and deployment of effective technologies (robert et al., 2022) in its ar5 of 2014, human input contributed to the rise in atmospheric temperature especially the through the emission of co2 in manufacturing plants, and vehicular activities. this is traced to the emergence of the industrial revolution. consequently, greenhouse gas emissions into the atmosphere have increased tremendously, particularly due to industrial growth in the world population. according to this group of scientists, there is an undeniable connection between industrialization and human civilization. however, the report concluded that there is a very high probability that the release of ghg through humanrelated activities is the most dominant driver of the increase in the earth's surface temperature from 19512010, coupled with other anthropogenic forcing acting together. (marcelo et al, 2018; aidonojie et al, 2022). from the preceding analysis, it goes without saying that among the two drivers mentioned earlier, human-induced greenhouse emissions have the most profound impact on ozone layer depletion and the notorious greenhouse effect compared with natural processes. essentially, nature’s contribution to the release of greenhouse gases, according to gupta and pennan (2022) occurs predominantly during a volcanic eruption, in which co2 is released into the atmosphere. however, the amount of c02 released during this period of volcanic activity is small concerning the global sustainability research global scientific research 38 amount emitted by human activities. in addition, the variation in solar radiation, changes in the earth's orbital activities, and rotation around the sun are other natural processes that contribute to climate change. the effect of climate change on biodiversity several studies have sought to give a pragmatic explanation with empirical certainty, the apocalyptic effect of climate change on biodiversity as a result of extreme weathers events culminating in the loss of natural habitat for various terrestrial and aquatic species, depletion of the world population through death triggered by heatwaves, storms, drought, cyclone, harmattan, and floods. the effect brought by the change in climatic composition, no doubt, is staggering. notably, the most affected component of the ecosystem is the alteration of the structure of the natural habitat for diverse species. as a result of a change in the average weather condition, extreme events have progressively impacted biodiversity globally. while the effect may differ across continental lines, the general effect is that it alters the ecosystem and exposes the species to hazards. due to the disproportionate annual rainfall, intense flood, and wide fire in the ecosystem, many biological species have been forced to relocate and secure an adaptable environment for their continuous existence. while unable to safely migrate to a new geographical location, they will have to exit the lifecycle, thus, shrinking the already depleted population of the species. the gradual extinction of some endangered species is more worrisome, mainly in the savannah or african region. water supply and controlled temperature are the two components necessary for the survival of plants and animals. however, the shortage of water supply (its pollution) and the increasing atmospheric temperature are the major characteristics of global climate change, which can affect the continued existence of these species in the ecosystem. also, the abnormal rise in heat levels will affect agricultural practices. indeed, agricultural activities have been severely affected by the intensity and frequency of rainfall throughout the year, affecting productivity. in the same vein, the dropping of acid rain in some climes is known to have a destructive effect on farm products. this also has a catastrophic impact on global food security (marcelo et al, 2018). it should be noted that environmental disruption is not new to our ecosystem. however, the current climate change has the potential to endanger all species found in both aquatic and terrestrial environments, including man. the adaptation in the species transformation in the new environment only plays a minimal role in its survival (robert et al., 2022). furthermore, he observes that the behavioral, morphological, and physiological modification of species is most times the direct response to the change in climate conditions. for example, he said painted turtles grew larger in warmer years and attained sexual maturity faster during warm seasons. many nations depend on the interactions within and around the aquatic environment. however, with the rise in sea temperature coupled with the shrinking of the glacial, activities in aquatic habitats have dwindled. considerable evidence has shown that ice will continue to melt, the ocean will rise, and the human mortality rate will increase due to the rise in air and water pollution. also, for instance, in bangladesh, it was observed that the problem of an outbreak of cholera was high due to the abnormality in the frequency of rainfall. the same is predicted for other developing countries with poor water and sewage infrastructures. aside from these social factors, global warming has been detected to impact the spread of infectious diseases depending on the countries’ socioeconomic conditions (abejon and garea, 2015). speaking on the impact of climate change on the world’s ecosystem, endre ivinnereim (augustine, 2021) rightly stated that climate change is a problem with global consequences. according to him, the consequence of global warming can not be fenced off but may be mitigated. this explains the collective responsibility approach by international policymakers like the united nations. by mitigation, we mean the human strategy or activities employed to reduce the human-induced emission of greenhouse gases into the atmosphere by national governments, companies, and more recently by an individual with appreciable knowledge of the impact of climate change on biodiversity. for instance, greta thunberg, the young environmental activist, became famous after her protest at the swedish parliament in 2018. since then, her campaigns brought other teenagers and college students like herself from european nations and some asian countries to the awareness of the devasting impact of global warming. a fallout of this collective responsibility by the international community is driven by the desire to reduce the anthropogenic emission of ghg through active implementations of policies, agreements, and protocols. for instance, the united nations framework convention global sustainability research global scientific research 39 on climate change (unfccc) is believed to be the first and major international treaty addressing the emission of ghg and its associated kyoto protocol (1997). however, relevant stakeholders and observers have heavily criticized these regimes for lacking the necessary ‘binding’ ingredient for proper implementation needed to flatten the curve and prevent further deterioration of biodiversity in the ecosystem. however, a significant portion of eu countries having the foresight of the impact of global warming on natural habitats have taken the initiative to limit industrial emission of ghg within their jurisdiction despite the nonbinding nature of these international treaties/agreements. it is indisputable that ‘we,’ including the biological species, are most vulnerable to climate change. evidence shows that several biological species which are unable to adapt have gone into extinction. global warming is a precarious phenomenon introduced by man and has an irreversible consequences if proactive steps are not taken. this truth was rightly emphasized by antonio guterres, the united nations secretary-general. in his opening remarks at the katowice climate change conference (cop 24) in 2018, when he said “we are in trouble” in a rather apologetic appeal for urgent action, he added, “we are in deep trouble with climate change.” in his speech, he noted that the concentration of c02 in the atmosphere was the highest in 3 million years and still growing. the legal challenges concerning preservation and conservation of biodiversity given the causes and effects of climate change on biodiversity, it suffices to state that the international community has through various methods and legal frameworks curtail some of these challenges in mitigating the conservation of biodiversity. however, despite the efforts of the international community to preserve and conserve biodiversity, there are still major challenges mitigating the smooth operation of the international community in preserving and conserving biodiversity. some of these challenges are examined as follows; poor level of implementation and enforcement however, it is also relevant to note that some member states, such as some developed and developing member states who are the signatory to most international treaties, conventions, and protocols, have refused to accede or comply with the directive in most relevant international law environmental regulatory framework concerning biodiversity. this is concerning the fact that there are poor enforcement methods and implementation of the concerned international treaties. for example, most developed and developing countries have refused to commit themselves to reduce the emission of methane (ch4), carbon dioxide (c02), and nitrous oxide (n20), undue exploitation of the environment as stipulated by the various global environmental legal framework. however, despite this violation by members state, there are no strict penalties or deterrents from refusing to commit themselves to preserving and conserving the climate of earth, which will protect and conserve biodiversity. currently, the hash and drastic climate change affecting biodiversity and climate earth is a pointer to the fact that most countries are still carrying out harmful activities that are detrimental to biodiversity and climate earth. furthermore, it also suffices to state that most conventions or treaties concerning the preservation and conservation of biodiversity often rest the responsibility of enforcement and implementation on member states. for example, the convention on international trade in endangered species of wild fauna and flora tends to place restrictions on preserving and conserving them against indiscriminate harvesting and use without due permission from the appropriate body (that is, members' state). this concerns that articles iii, iv, and v of the convention on international trade in endangered species of wild fauna and flora protect endangered species from indiscriminate exploitation. the provision stipulates that member states must have prior approval in importing or exporting any wild fauna and flora red-listed in appendix i, ii, and iii of the convention. furthermore, article viii of the convention concerning trade in endangered species of wild fauna and flora empowers contracting states that where there is a violation of the convention, an appropriate measure in enforcing the provision of the convention. given the above, it suffices to state that giving members state the sole responsibility in implementing and enforcing issues as it affects the global environment may be detrimental and lead to inadequate implementation and enforcement. this is concerning the fact that most members state may not have the capacity to ensure sue implementation and enforcement like an international institution or body. global sustainability research global scientific research 40 inadequate or lack of commitment by members state concerning this study, it has been identified that several international environmental legal frameworks tend to provide for the preservation and conservation of biodiversity. however, irrespective of the above relevant legal framework concerning biodiversity, it suffices to state that one of the challenges mitigating the preservation and conservation of biodiversity could stem from the fact that there are poor or low levels of commitment by most member state in acceding to the agreement as contained in the various international environmental treaties. for example, in 1997, nations had to come together during the kyoto protocol to proffer an enabling solution in curtailing, reducing, and mitigating the level of industrial activities that release gasses that cause global warming. in this regard, the kyoto protocol was adopted due to the drastic emission or release of greenhouse gasses concentration in the atmosphere, thereby causing climate change and global warming, which had most of its challenges with member states committing themself to the protocol. this is concerning the fact that nations such as usa and china withdrew their membership. given that the usa and china withdrew their commitment to the protocol in 2012, canada also withdrew from the summit. their withdrawal is because the biggest two emitters (china and the usa) are not part of the protocol agreement. furthermore, given the fact that it will amount to the canadians to reduce their industrialization and employment opportunity drastically. according to the canadian environment minister, he said "the kyoto protocol does not cover the world's largest two emitters, the united states and china, and therefore cannot work," kent said. "it's now clear that kyoto is not the path forward to a global solution to climate change. if anything, it's an impediment." signing kyoto was one of the previous government's biggest blunders, allowing us to continue creating jobs and growth in canada. this is concerning the fact that, if members state has effectively complied with the directive as regards, the reduction of emission of water vapour (h20), methane (ch4), carbon dioxide (c02), and nitrous oxide (n20), reduction of bush burning as stipulated in global environmental treaties and convention, the level of drastic climate change affecting biodiversity would have been curtailed or minimize. however, the current report has shown that climate earth is still severely undergoing global warming and climate change, owing to harmful activities of man that are catastrophic to climate earth. national legislation constrain in implementing international treaties although most nations have seen the need to form an international institution in resolving issues that tend to have an international flavor. however, the various international laws that have been enacted recognize the fact that members state still possess sovereign power within their society or state. they are exercised and realized in distinct ways. in this regard, virtually all countries' constitution provides for their sovereignty and supremacy of their contents. therefore, any law inconsistent with the said provision or content of the constitution will be declared null and void. concerning this, it suffices to state that, in most developing countries, their constitution places restrictions or constrains concerning the recognition and enforcement of international treaties, conventions, and protocols. for example, in nigeria, virtually all international treaties, conventions, and protocols are not enforceable by section 12 (1) of the nigeria constitution, except such international instruments have been domesticated by the national assembly. section 12(1) of the nigeria constitution provides thus; no treaty between the federation and any other country shall have the force of law to the extent to which any such treaty has been enacted into law by the national assembly. this position of the nigeria constitution has been aptly given judicial recognition in the case of abacha v. fawehinmi (2000) 6 nwlr (pt. 660) p. 228 at 228, where ogundare jsc held that before an international treaty becomes binding and enforceable in nigeria, such treaty must be enacted into law by the national assembly. also, in the case of mhwun v. minister of health & productivity & ors (2005) 17 nwlr pt. 953, p. 120, the court held that the provisions of an international labour convention could not be invoked and enforced by nigeria court unless an act of national assembly has domesticated it. the above provision of the nigerian constitution serves as a constraint and restriction on the international global sustainability research global scientific research 41 environmental legal framework concerning the preservation and conservation of biodiversity within the nigerian territory. poverty and poor level of technological development in most developing countries given the level of poverty and slow pace of technological development in most developing states or countries, it may also serve as a challenge in ensuring the effective preservation and conservation of biodiversity. this is concerning the fact that these developing countries may not have the capacity to adapt or adopt sophisticated technology or scientific method that could preserve and conserve biodiversity. in this regard, given the poor level of their economy and technological development of most developing countries, it may lead to such countries engaging in some industrial activities that could be harmful to biodiversity. the possible ways of revamping the conservation and preservation of biodiversity varied predictions on the effect of climate change on the natural system indicate that delay in mitigation may cause irreversible consequences on the ecosystem. in this regard, the timely intervention, the environment, and diverse species (plants and animals) in the ecosystem may be conserved or salvaged from the brink of extinction. given the above, it suffices to state that the following mitigating measure that could revamp and complement the available international environmental legal framework should be considered if the ecosystem will be preserved. a. role of the government of signatory states in the conservation of biodiversity the essence of the calls for sustainable development that ensures the effective preservation of biodiversity by the international community through the relevant legal framework is very pertinent to the existence of man and its environment. however, the protection of and conservation of biodiversity cannot be fully realized without the stake input of signatories' states in their respective domains. this is concerning the fact that the aim and essence of the relevant international legal framework that tends to preserve and conserve biodiversity will only have a better effect of implementation if, at the local level, there are legal frameworks that provide for the preservation and conservation of biodiversity within their territory. in this regard, it suffices to state that the government of all signatories should, through national environmental legislation, replicate most of the provisions of the international ecological legal framework that curtails the ongoing activities (such as the emission of methane (ch4), carbon dioxide (c02) and nitrous oxide(n20), undue exploitation of the environment and bush burning) that destroy biodiversity. furthermore, states party must go through administrative measures to take proactive preventive and protective measures concerning the preservation and conservation of biodiversity. some of these administrative measures that could be adopted in ensuring the preservation and conservation of the marine environment; i. setting up a task force to curtail incessant and indiscriminate exploitation of biodiversity and curtailment of bush burning ii. declaring specific days for environmental sanitation iii. setting up a mobile court to summary try individuals violating or refusing to adhere to environmental sanitation that seeks to curtail minor pollution within their environment however, irrespective of the above, the government of the signatory state should endeavor to create a lilly way for effecting and implementing an international environmental legal framework concerning biodiversity. in this regard, there should not be any national or state constitutional and legal restrain restricting the international community from effectively implementing the relevant international environmental legal framework concerning biodiversity within members or signatory states. furthermore, given the global-scale impact of climate change, collective international policies are needed to utilize regional support effectively. b. adopting a new scientific method that compliments relevant international legal framework on biodiversity the need to develop international and states environmental law was triggered and necessitated by the need to protect life and preserve the ecosystem from hazardous substances that may be very harmful and result in the pollution of the environment. however, it suffices also to state that the introduction of hazardous substances to the environment that results in the depletion of the ozone layer is mainly a result of the harmful industrial global sustainability research global scientific research 42 activities of humans arising from exploiting natural resources of climate earth. therefore, given the harmful activities of human industrial activities, it has degenerated into an environmental problem such as pollution of the environment, deforestation, desertification, acid rain, the destruction of the ozone layer, and climate change. it concerns the above that a scientific researcher has scientifically driven them in inventing scientific methods to preserve and conserve climate earth, which will ensure the conservation of biodiversity. it must be noted that one such scientific method that has been adopted is nanobiosensor. according to scientific study, nanobiosensor has been scientifically proven to be relevant in various scientific research. this is concerning the fact that the introduction of the scientific concept of nanobiosensor for environmental monitoring is aimed at ensuring prevention and control of the introduction of hazardous substances or constituents that may contaminate or pollute the environment (vincent et al., 2015). furthermore, another scientific discovery that could also be relevant in conserving and preserving biodiversity is nanotechnology. according to a scientific study, nanotechnology involves the designing and making use of devices and systems ranging from 1-100 nm scale (fei ma and chun-yang, 2018). the relevance and essence of utilising nanotechnology are based on the sensing and detection of harmful substances that could cause pollution. in this regard, the use of nanotechnology involves the use of nonmaterial in detecting pollutants and hazardous substances (nafiseh et al., 2016). given the above, it suffices to state that given the relevance of current scientific discovery (such as the nanobiosensor and nanotechnology that complement and strengthen the already existing international environmental legal framework for conservation and preservation of the environment) as relating to scientific preservation of the environment, such scientific measure should be adopted to complement the implementation of the current international legal framework as it relates to the preservation of biodiversity. c. strict sanctioning erring countries or states violating international legal framework on biodiversity however, despite this violation by members’ states, there are no strict penalties or deterrents from refusing to commit themselves to preserve and conserving climate earth, preserving and conserving biodiversity. it suffices to state that most developed and developing countries have refused to commit themselves to reduce the emission of methane (ch4), carbon dioxide (c02), and nitrous oxide(n20). furthermore, it was also observed that the continuous and undue exploitation of resources within the environment is prohibited by the various global environmental legal frameworks. this is concerning the fact that the current hash and drastic climate change affecting biodiversity and climate earth is a pointer to the fact that most countries are still carrying out harmful activities that are detrimental to biodiversity and climate earth. in this regard, the international community must, via the relevant international legal framework and various mechanisms, ensure strict compliance of members’ state of the various scheme stipulated in an environmental legal framework to ensure proactive conservation and preservation of biodiversity. furthermore, it is also required that the international court of justice should be given adequate judicial power concerning erring states whose activities tend to pose a threat to climate earth d. re-engineering the polluters-pay principle with strict liability it suffices to state that the need for the protection of climate earth biodiversity should not only be statutorily recognized. rather there should be an imposition of strict liability where polluters are strictly held responsible for any of their actions that threaten the biodiversity of their neighboring state or within the international community. these principles of polluters pay have been aptly observed by the court in trailsmelter case (xingang et al., 2022). the principles seem to have been adopted in several cases in the past, such as the netherland case that occurred in 2008. in the netherlands case, four nigerian farmers and with some relevant stakeholders of the international community known as friends of the earth filed a lawsuit concerning shell company oil spillages in three villages in nigeria. in deciding on the lawsuit, the dutch court issued a decision compelling shell company to pay compensation to the farmers and ensure clean-up of the affected community. furthermore, in the lawsuit of united states of america v. shell offshore inc. and shell exploration and producing company, shell company was ordered by the court to pay forty-nine million dollars ($49,000,000) for engaging in an unauthorized gas flaring. the above represents the practice of polluters pays principles in the past; however, there seems to be a global sustainability research global scientific research 43 lack or inadequate use of the polluters pay principles against those whose activities endanger the climatic biodiversity. hence, it is required that the international community ensure that the polluter's pay principles are incorporated into international treaties and conventions and ensure effective enforcement and compliance of the polluter pay principles. e. mitigate greenhouse gases emission (decarbonization) having noted that the most dominant ghg emitted daily by human activities is co2, and the same is released during fossil fuel combustion, a drastic reduction is required to keep the earth at a low temperature. adopting friendly environmental technologies is key. such mitigation procedure is in line with article 2 of the unfccc. f. reforestation and effective forest management the farm practice of deforestation should be discouraged. deforestation contributes significantly to the emission of co2. according to anuradha et al., deforestation contributes approximately a quarter of the increase in the level of co2 in the atmosphere. thus, reforestation may be a viable option for restoring the needed balance in the ecosystem. it should be noted that in the event of wildfires occasioned by climate change, there is usually a structural imbalance for most organisms in the forest. the herbivorous habitat is primarily affected, leading to shifting geographical locations with attendant hazards to predators along the way. to curtail this climate change, as an alternative to reforestation, anuradha et al. recommended that forest management practices be implemented to enable the forest to cope with forest disturbances under climate. g. encourage the use of renewable energy the fact that a large percent of the world population still depends on fossil fuels for energy is evident in the everglobal increase in temperature. however, many nations and multinational companies have started investing in alternative energy sources (wind and solar). renewable energy help to reduce the amount of pollution in fresh water and the marine environment. for instance, many regions rich in biodiversity and marine life have been negatively affected during explorative activities for mineral resources. conclusion this study has identified that climate change and global warming arising from harmful human activities pose a great danger to climate earth's biodiversity. the study also observed that the conservation and preservation of climate earth biodiversity is a key and a central focal concern of the international community. this is concerning the fact that several international environmental laws concerning the preservation and conservation of climate earth biodiversity have been agreed on and adopted by members of the international community. however, the study further identifies that despite the various international environmental legal frameworks concerning the preservation of climate earth biodiversity from harmful human activities. there is still an increased rate of deterioration of climate earth biodiversity arising from the detrimental activities of humans. the reason for the current increase rate of climate earth biodiversity stems from various reason which has been identified in this study above. hence, concerning these challenges, the study tends to identify some probable solutions in revamping the international environmental legal framework concerning the preservation of biodiversity as follows; i. the government of signatory states to international environmental treaties, conventions, and protocols in biodiversity conservation must ensure they commit themselves to their role as stipulated in the various international environmental legal frameworks. ii. there is a need to adopt a new scientific method that compliments relevant international legal frameworks on preserving biodiversity. iii. the international community must adopt a strict sanctioning method against erring countries or states violating biodiversity's global environmental legal framework. iv. the international community should re-engineer the polluters-pay principle with strict liability against erring states whose activities threaten their neighboring state. acknowledgment: none funding: none conflict of interest: the

environmental impact; economics; renewable; sustainability introduction as the global economy grows, co2 emissions rise because of industrialization, deforestation, environmental damage, and the world's population (raihan et al., 2018; raihan et al., 2019; jaafar et al., 2020; raihan et al., 2021; raihan and tuspekova, 2022a). according to the world meteorological organization (2021), the amount of carbon dioxide in the air has increased by 2.5 times since the beginning of the industrial revolution. co2 can be emitted into the environment during the generation and consumption of energy (raihan and tuspekova, 2022b; raihan et al., 2022a; raihan et al., 2022b). the amount of greenhouse gases (ghgs) in the earth's atmosphere has significantly increased due to higher energy use and it has had numerous negative impacts on the environment, people's health, the economy, and many others (begum et al., 2020; raihan et al., 2022c; raihan and tuspekova, 2022c). more than 80% of the world's energy needs grew between 2000 and 2010. most of this growth was made possible by using more than twice as many fossil fuels. over 90% of all co2 emissions and over two-thirds of all ghg emissions come from burning fossil fuels and biomass (raihan and tuspekova, 2022d; raihan et al., 2022d). this makes co2 the most critical factor in determining the overall ghg emissions trend (raihan and tuspekova, 2022e; raihan et al., 2022e; raihan et al., 2022f). most of the emissions in many countries come from the transportation and energy sectors (raihan and tuspekova, 2022f; raihan and tuspekova, 2022g). since 2000, the oecd's economy has grown steadily, but co2 emissions related to energy have gone down. this has happened because of changes in the economy's structure and the energy supply and because manufacturing has become more https://doi.org/10.56556/gssr.v1i2.327 mailto:litonvoumik@gmail.com mailto:mjirafi.thm@nstu.edu.bd mailto:asifraihan666@gmail.com mailto:asifraihan666@gmail.com global sustainability research global scientific research 13 energy efficient. most oecd countries are on track to meet their kyoto protocol emission reduction goal although the progress is not good enough. because energy use and co2 emissions have recently increased, ghg levels will likely rise. approximately 29% of ghg emissions in oecd countries come from the energy sector, 24% from transportation, 13% from manufacturing, 9% from agriculture, 7% from industrial processes, and 3% from waste (iea, 2019). after three years of stability, co2 emissions from the world's energy sector hit a record high of 32.8 billion tons in 2017. in 2018, the average amount of co2 each person in oecd countries put into the air was 8.7 tons, while the average amount for the rest of the world was 4.3 tons. rapid economic expansion in oecd nations has coincided with an increase in energy usage for manufacturing, industrial, and service-oriented economic activities. carbon, which is mainly used to make electricity and makes up most of the area's energy mix, has been the fastest-growing energy source in the oecd region over the last ten years. even though this has helped the region grow and become more industrialized, it has also increased co2 emissions from energy use and air pollution, which is detrimental to human health (raihan and tuspekova, 2022h). access to electric power sources has increased dramatically since 2000. nonetheless, 45 million individuals living in the oecd region still don't have access to electricity, and many use biomass energy as their primary source of cooking fuel (iea, 2019). however, energy consumption in oecd countries has been rising at a rate of 6% annually, indicating that the region's electric grid is having trouble covering its costs due to rapid population growth (iea, 2019). in terms of global power consumption, it has been one of the regions with the quickest growth rates, with oecd nations leading the way. indeed, the region has come a long way toward its objective of ensuring that everyone has access to power by 2030. there may be numerous advantages to producing electricity for human usage. it could, however, hurt the environment and people's lives (raihan and tuspekova, 2022i; raihan and tuspekova, 2022j). electricity can be produced in several ways, not all of which have the same environmental impact. compared to other forms of renewable energy, such as solar power, the environmental impact of coal is substantially larger. in addition to nuclear and hydroelectric power facilities, oil can also be used to generate electricity. coal, oil, and natural gas are frequently burned to generate electricity (raihan and tuspekova, 2022k). these factors contribute to the increase of carbon dioxide in the atmosphere. however, the location of power generation, transmission, and distribution can significantly alter the environmental consequences of the power system. electric power systems also include transmission networks, distribution lines, and power plants that generate electricity from various fuel sources. both the production and consumption of these items have the potential to have an impact on the natural world. construction, electricity generation, component isolation, and separation fall within this category. the functional and construction effects can be further subdivided into operational effects (such as fuel sources and global and local pollutants) and building effects (manufacturing, installation, decommissioning, and disposal). however, energy-producing co2 emissions have not been the focus of any gmm or qr-based studies in the oecd region. therefore, this research intends to identify a connection between co2 emissions and the sources of power generation in the oecd region using various methods, including system gmm, difference gmm, and quantile regression. this article illustrates how much carbon dioxide is released from coal, gas, and oil electricity production in oecd countries. this study also demonstrated the advantageous effects of non-conventional methods of electricity production on the environment. this investigation aims to discover evidence that hydropower and other renewable energy sources can aid in decreasing waste and pollution. the environmental policy has been suggested in the article with the knowledge gained from this investigation. literature review the literature review overviews the relevant publications picked for the study endeavor. numerous works have examined the relationship between power generators, renewables, and emissions of carbon dioxide. on the other hand, it's unclear how things happened because they happened in different ways, in different countries, and at different times. how much energy we use and how that affects co2 emissions is a big worry for people living now and in the future. global citizens are already planning for the future consequences of climate change. because of the harm, it does to the ecosystem; this is a dangerous situation. dantama et al. (2012) reported that electricity influences all spheres of society, from the working class to the upper crust. according to numbers from 72 different countries, global co2 emissions increased from 67 million metric tons in 1990 to 134 million metric tons in 2012. so, environmental pollution kills more than 150,000 people yearly (amri, 2017). furthermore, ozturk (2010) also linked various energy sources to economic growth. he examined several electricity sources. population size, the quantity of renewable, fossil, and carbon-intensive energy used, nuclear-intensive energy used, over dense cities, and detrimental air pollutants like pm10, pm2.5, so2, no2, co, and benzopyrene have all been related to the rise in global co2 emissions (talbi, 2017). they also showed how these variables enhance global co2 emissions. geothermal plants emit co2 due to their high temperatures (300–700 °f). the association between energy use, gdp expansion, and co2 emissions were examined using granger causality and panel cointegration (kristmannsdóttir and armannsson, 2003). 70 countries' worth of data were analyzed from 1994global sustainability research global scientific research 14 2013. granger causality studies show that the two are related to one another in terms of energy usage and carbon dioxide emissions. cointegration tests demonstrated a long-term relationship between the variables of interest (economic growth and energy consumption) and co2 emissions. as a result of process fixes, rising energy use and economic growth led to lower co2 emissions. economic activity, electricity concentration (demand strategy), heat production (supply strategy), and carbon emission index are all taken into account in this method of categorizing co2 emissions (demand policy effort). eu nations cut co2 more than noneu nations. reducing thermal power and increasing energy efficiency drove policy. these increases may be due to a shift in generation mix or higher power use. scientists proved it (kim et al., 2020). massive energy use and co2 emissions threaten future generations. droughts, melting glaciers, rising seas, global warming, and heat waves are already happening. negative environmental effects threaten the ecology. between 1992 and 2018, awosusi et al. (2022) analyzed the impact of brics biomass energy use. environmental degradation is a byproduct of economic development, increased use of natural resources, and rising levels of gross capital. the research of aydin (2019) relied on brics statistics from 1992-2013. biomass energy's economic significance was emphasized. the heterogeneous panel data study benefited several nations. biomass energy use is key to economic growth and reducing imports. shisong et al. (2018) employed a quantile regression panel approach to estimate co2 emissions. according to their analysis, nonrenewable energy reduces co2 emissions the greatest. it is detrimental for high-emission nations to have little involvement in developing ecologically sound sources of power. yu et al. (2019) investigated the effect of energy output on industrial development and long-term economic growth by concentrating on the nations with the most significant gains in power generation between 2000 and 2018. from 1991 to 2018, the brics nations' electricity production contributed to industrial output and sustained economic growth. a few examples of these fields are manufacturing, raw materials extraction, mining, and chemical synthesis. it has significantly increased the electrification of all enterprises and households during the previous three decades (wang et al., 2010). apparently, the causal relationship between energy generation sources and co2 emissions has not been explored in oecd states. in addition, no other studies used system gmm, difference gmm, and the qr approach to uncover useful information on co2 emissions from various power production sources in oecd countries. consequently, the present study’s results would help close a gap in the existing body of literature by using various econometric methods to identify a connection between co2 emissions and the sources of power generation in the oecd region. methodology data and variables of the study data for 38 oecd countries were obtained from the world bank's world development indicators (wdi) database on an annual panel basis from 1986 to 2020. there are currently 36 member states of the oecd: slovak republic, slovenia, spain, czech republic, denmark, estonia, finland, france, netherlands, norway, poland, portugal, luxembourg, greece, hungary, iceland, ireland, italy, latvia, austria, belgium, japan, korea, new zealand, israel, switzerland, canada, chile, colombia, mexico, costa rica, the united states, australia, sweden, germany, turkey, the united kingdom, and lithuania. the following elements are taken into consideration (table 1): table 1. a brief overview of the parameters name of the variables variables in log form elaboration of the parameters co2 l(co2) co2 emissions (kt) coal l(coal) percentage of total electricity production that comes from coal gas l(gas) percentage of total electricity production that comes from gas nuclear l(nuc) percentage of total electricity production that comes from nuclear hydro l(hydro) percentage of total electricity production that comes from hydro oil l(oil) percentage of total electricity production that comes from oil renewable l(renew) percentage of total electricity production that comes from renewable resources excluding hydro for a complete breakdown of how each variable was measured, the median, mode, standard deviation, and extreme values are displayed in table 2. co2 has an average value that is greater than those of the other variables. global sustainability research global scientific research 15 table 2. synopsis of descriptive statistics variables number of observations mean standard deviation minimum maximum l(co2) 1172 11.17 1.707 5.458 15.57 l(coal) 891 2.760 1.787 -6.483 4.587 l(gas) 988 2.162 1.756 -4.785 4.599 l(oil) 1071 0.864 2.017 -6.091 4.605 l(renew) 961 0.467 1.924 -8.028 4.181 l(hydro) 968 1.860 2.253 -6.528 4.601 l(nuc) 867 3.347 0.789 -2.433 4.477 econometric model specification coal, gas, oil, renewable energy, nuclear, and hydroelectricity are the main ways electricity can be produced. though there are many ways to produce electricity, but there is no available data for these sources. using the standard methodological approach, this investigation controls co2 emissions by measuring the impact of power generation from coal, natural gas, nuclear, hydroelectric, oil, and renewable sources. the following equation (1) may be used to determine the influence of dependent and independent variables. co2 = ƒ (coal, gas, oil, renewable, hydroelectric, nuclear) (1) notably, no dummy variables were included; all variables were classified. this is because it is anticipated that data behavior would not change over time. the multivariate econometric model is depicted in equation (2). (co2)it = β0 + β1(coal)it + β2(gas)it + β3(oil)it + β4(renew)it + β5(hydro)it + β6(nuc)it + εit (2) the log transformation has been taken in equation (3). l(co2)it = β0 + β1l(coal)it + β2l(gas)it + β3l(oil)it + β4l(renew)it + β5l(hydro)it + β6l(nuc)it + εit (3) where β0 is the intercept term. β1, β2, β3, β4, β5, and β6 are the slope coefficients. the ε is present the residual, and i presents the cross-section country, t presents the time. gmm approach researchers often utilize both fixed and random effects models when studying topics such as international trade, environmental policy, and economic development. the dynamic gmm model, developed by arellano and bond (1991) has only recently begun its operations in these sectors. this study used models with fixed and random effects separately so that their findings can be compared with those obtained from our dynamic model. in order to conduct an investigation into the co2 emissions, a two-stage "differenced" and "system" gmm model has been included in this investigation. formulae for the differenced gmm and system gmm can be displayed as equation (4) and equation (5). l(co2)it = β0 + β1l(co2)it + β2l(coal)it + β3l(gas)it

quantile regression method is to study outcomes that aren't normally distributed and don't have linear relationships with predictor factors. buchinsky (1994) states that to describe the possible different effects, it needs to identify the qth-quantile (0< q<1) of the dependent variable as a temporary distribution, given a set of xi variables as follows: qq (yit | β0, εit, xit) = β0 + εit q + βi q xit (6) where yt indicates the rate of co2 emission over time. as seen by the following objective function, inference from the qth quantile regression requires minimizing the absolute value of the residual. quantile regression is presented in equation (7). qq (βi q ) = min β ∑ ⃦ n q,i,t=1 yit − xitβi q ⃦ = min [ ∑ q│yit − xitβi q │ +i:yit≥xitβ ∑ (1 −i:yit˂xitβ q)│yit − xitβi q │] (7) global sustainability research global scientific research 16 results and discussion correlation analysis is crucial to know if there is a positive or negative correlation between the variables in the study. when two variables have a positive correlation, it can say that they are positively covariant. negative covariance is formed when two variables have an inverse relationship. table 3 correlations show a positive relationship between l(co2) and l(coal), l(oil), and l(gas). the correlation between l(co2) and l(coal) is the highest and most significant, while the correlation between l(co2) and l(gas) is the lowest and least significant (0.014). similarly, the strongest positive correlation is found between l(co2) and l(coal) and the value is 0.360. there are no correlation coefficients that are greater than 0.80 between any of the variables in this research. as a result, there is no multicollinearity and the study's variables are not linked to one another. to a lesser extent than l(nuc), l(renew), and l(hydro) have a negative correlation with l(co2). table 3. indicators of variable correlation variables l(co2) l(coal) l(gas) l(oil) l(renew) l(hydro) l(nuc) l(co2) 1.000 l(coal)

debate on how to interpret the results. this note elaborates on how the rejection of the panel unit root hypothesis can be read as proof that a sizable fraction of the units are stationary. for this reason, it is suggested that, in the case of a rejection, especially in contexts where the temporal dimension of the panel is quite large, the test outcome be supplemented with an estimate of the fraction of the cross-section units for which the individual unit root tests are rejected. the rejection's monetary impact can be gauged by how much this percentage rises (pesaran, 2012). the outcomes of a unit root test for the dependent and independent variables are shown in table 4 for both the raw data and the first difference levels. specifically, it shows that h(0) has a unit root since it is non-stationary, while h(1) does not. it is evident that all of the parameters are locked in at h(1). the null hypothesis is rejected with a confidence level of 5% if there is even a nominal difference between the two variables. the dependent and independent variables are anticipated to follow a unit root distribution. here, the investigation would reject the null hypothesis if the p-value is less than 0.01. as shown in table 5, the log-log model estimates both fixed and moving information panels. the coefficient of co2 emissions and electricity output from various sources are presented in columns 2 and 3 of the model. the coefficient represents a percentage change in co2 emissions due to a percentage change in the independent variables. our model's dynamic panel regression is shown in columns 4 and 5. the estimate is statistically significant and positive, with coefficients of l(co2) for explaining l(coal) of 0.108*** and 0.109*** in the fixed and random effect models, respectively. the differenced gmm model predicts a 0.0629 percentage point rise in co2 emissions for a one percent increase in l(coal), while the system gmm model predicts a 0.00802 percentage point decrease. direct sources of co2 emissions are important, but indirect sources global sustainability research global scientific research 17 including hard coal, natural gas, and non-energy consumption also contribute significantly (huang et al., 2018). for cases where both l(coal) and l(oil) are major contributors to increasing co2 in a given panel research region, the second-phase output is determined by the dynamic gmm model. l(renew) exhibits a -0.0101 and 0.0101 coefficient weighted negative and significant effect on l(co2) in both the fixed and random effect models. for the differenced gmm model, a 1% increase in l(renew) leads to a 0.00605% rise in co2 emissions, while for the system gmm model, the growth is only 0.00485%. in the same way, the differenced gmm model predicts a 0.0417% drop in co2 emissions for a 1% rise in l(hydro), while the system gmm model predicts a 0.0042% drop. table 5's haussmann chi-square value of 18.52** favors the fixed-effect model over the random-effects model, with a significance level of 0.125. the system gmm model only differs considerably in sign and direction from the fixedeffect model for l(oil). to ensure the internal consistency of the system gmm estimate, it is assumed that the error term is not serially correlated. due to the low ar-2 values for both models, we cannot conclude that the firstdifferenced error at order 2 is serially correlated. methods that can be relied on are required for use in gmm estimations. applying the sargan and hansen tests for overidentifying constraints in estimation allows one to examine the general validity of an instrumental variable. the null hypothesis assumed that all instruments were reliable because they were considered exogenous. this study shows that the hansen test returns probabilities between 0.243 and 0.415. on the other hand, the sargan test statistics of the present investigation yield probability values of 0.250 and 0.284. the null hypothesis that the instruments are reliable, was accepted for both. table 5. dynamic and static panel regression result variables fixed effect random effect differenced gmm system gmm l(co2) 0.716*** (0.0629) 0.980***

regression quantiles. the qr model considers all three of these frequencies: q25, q50, and q75. coal and natural gas power plants produce more carbon dioxide as they generate more electricity. in the qr models for q25, q50, and q75, the l(coal) coefficients to explain l(co2) are 0.0607, 0.209***, and 0.481***, respectively. there is a negative and significant effect on l(co2) from both l(renew) and l(hydro), except for q25. with quantile specific l(renew) values of 0.0235, -1.102*, and -0.0327, respectively, a 1% increase in l(renew) sources generates a co2 emission barrier of 0.024%, 0.10%, and 0.034%. there is a statistically significant inverse relationship between carbon emissions and the generation of power from renewable and hydroelectric sources; this is an important factor to consider. power generation from renewable, oil, and hydroelectric sources can thus contribute to improved environmental quality by lowering atmospheric carbon emissions. in addition, less carbon dioxide is released into the air when power generation is more streamlined. global sustainability research global scientific research 18 table 6. quantile regression outcomes variables panel ols q25

exacerbated by these countries' use of fossil fuels for energy production, particularly coal, oil, and natural gas. the present study focused on answering the question of what can be done to reduce the carbon dioxide emissions of power plants. it is untrue to assume that the only way carbon dioxide is released into the atmosphere is through the burning of fossil fuels like coal, oil, and gas. our novel approach to this issue is based on a hybrid of the conventional least squares method, a variant of the method of moments, and the quantile regression technique. no other scientific study has ever attempted something like this before. because this study care about the accuracy of both the methods and results, this investigation consistently mixes the two. massive increases in co2 emissions are produced when fossil fuels like gas, coal, and oil are burned. it is possible that switching to renewable energy sources like hydropower might drastically reduce pollution levels (voumik et al., 2022a; voumik et al., 2022b; voumik et al., 2022c) the gmm method proves that burning coal and extracting oil are the two leading causes of co2 emissions. co2 emissions may be reduced, however, if power is generated from renewable and hydroelectric sources, as shown by the gmm approach. quantile regression analysis of emissions data provides some context, showing that coal and natural gas are the two most important contributors to air pollution and, by extension, global warming. hydropower and other renewable energy sources have the potential to aid in emission reductions, as shown by the gmm and quantile regression methods. hydroelectricity and other forms of renewable energy are favored by all economic models as the most effective means of minimizing harmful effects on the environment (huang et al., 2018; aydin, 2019). coal-fired energy is much more damaging to the environment than other forms of pollution. this study’s aims are met as a result as well. it is generally accepted that the environmental impact of electricity generated by burning coal is more significant than that of power generated by burning oil or natural gas. however, hydroelectricity production is better for the environment than renewable energy sources that don't use hydropower. this paper's contribution quantifies how the independent factors affected the dependent ones. potentially significant long-term renewable energy sources include wind, solar, geothermal heat, and biomass. the majority of oecd countries get their power from coal and oil. coal and gas consumption in the oecd as a whole has expanded quickly since 1980; however, consumption has declined in some countries like new zealand and norway, and demand in the united states currently surpasses output, which is rising at a high rate. conclusions and policy implications this study examined the relationship between energy consumption and carbon dioxide emissions in oecd economies. using panel generalized methods of moments (gmm) and quantile regression, this research analyzed time series data on oecd nations from 1986 to 2020. the research empirically assessed the impact of different power generation sources on co2 emissions using quantile regression and generalized linear models (gmm). when compared to traditional statistical methods like ordinary least squares (ols), generalized linear models (glm), and additive random effects (ardl), quantile regression, one step-difference gmm, and system gmm provide a more comprehensive explanation of the overall dependence of energy generation from diverse sources on co2 emissions. as a result of their more significant outputs, coal and natural gas have more prominent production factors. production rates of renewable energy are inversely proportional to their ecological footprint. because of the positive ecological effects, renewable energy sources should be prioritized above traditional ones. co2 emissions and energy global sustainability research global scientific research 19 generating sources are positively correlated in oecd countries. hydroelectric power generation also can lessen its impact on the environment. thus, renewable energy sources are preferable to conventional electricity generation methods. natural gas and coal are two of the most widely used energy sources, and all of our models for oecd nations indicated a high positive correlation between the two in terms of co2 emissions. regardless, the oil-based power generation didn't give us any direct orders. this article provides a clear and consistent picture of the current state of renewable energy sources in oecd countries. since most oecd nations have abundant natural resources, this article shows they have a great chance to meet their overall power demand by using their renewable resources, such as solar, wind, geothermal, hydropower, ocean energy, and bioenergy. if they can maximize their usage of renewable energy sources, not only will their electricity needs be met at a low cost, but their co2 output may also be kept to a minimum. so, instead of relying solely on conventional ways, now is the time to look forward and collaborate with these renewable energy areas to produce electricity. there has already been some effort made by oecd governments to resolve the power situation. alternative energy sources, such as solar power, should be given more attention because they represent a promising new industry with the potential to supply the vast majority of the oecd's population's energy and power needs. combined with other forms of renewable energy, these can significantly help meet their daily power needs. oecd countries may be able to meet their future electricity needs using these resources to generate electricity. to alleviate the power shortage situation in their respective regions, governments and the private sectors should collaborate to emphasize using renewable energy sources for electricity generation. the article also provides a brief overview of the current state of renewable energy worldwide. with fossil fuel reserves continuously dwindling, the world must increasingly rely on renewable energy sources to keep up with increasing energy demands. by maximizing the utilization of renewable energy sources, this article is the first step toward building a completely uninterrupted power flow that is both environmentally friendly and efficient. funding: not applicable acknowledgments: not applicable conflict of interest: the authors declare no conflict of interest. references amri, f.

regional planning, university of calabar, calabar, cross river state, nigeria 2department of urban and regional planning, university of uyo, uyo, akwa ibom state, nigeria corresponding author: salvation u. eteng, salvationeteng@gmail.com received: 15 august, 2022, accepted: 27 september, 2022, published: 30 september, 2022 abstract the problems faced in slums go beyond defacing the city’s aesthetic quality and poor housing supply but extend to crime increase. in calabar, the weaknesses of the government/development partners towards preparing and implementing urban renewal programmes/projects has resulted in sporadic increase in the prevalence of slums. obviously, places of functional obsolescence with derelict features create breeding ground for crime to thrive. in calabar, areas mainly in the city core are characterized with moribund environments, deteriorating/deteriorated housing units and poor sanitation systems all of which points to slum development. crime is prevalent in such areas hence the need to carry out this study. the study focused on ascertaining slum prevalence and crime incidence. a sample of 400 respondents was taken using taro yamene formular. data were obtained from both primary and secondary sources. questionnaire and housing/environmental quality checklists were the major instrument for data collection. data were analysed using relative index, frequencies and percentages. it was noted in the study that slums are prevalent in the study area and it prevalence contribute to increasing crime levels. this is because the absence of certain facilities constrain security operation in the slum prevalent area. the study recommended that there should be urgent urban renewal in the study area. facilities and infrastructure that will increase security level should also be provided keywords: slum; crime; housing/environmental quality; urban renewal; sustainability introduction on a general basis, slums are developments that show attributes/characteristics of overcrowding, dilapidation, deterioration and poor environmental conditions. infrastructure, facilities and amenities are usually inadequate within such areas. in simple terms, slums are areas of severe deterioration and obsolescence. instances of infrastructure and facilities that are usually lacking in such areas include potable water, electricity, good roads, recreational ground, schools, clinics and communication facilities. however, the absence of adequate infrastructure and facilities endanger the health, safety and general wellbeing of residents within such deteriorating neighbourhoods. in other words, slums are areas of serious environmental degradation that are characterized by absence of facilities and services that are required to make urban living meaningful (ekundayo, faringoro and job, 2019). residents within slum areas are therefore subjected to inaccessibility to basic amenities and left to dwell in derelict and areas of functional obsolescence. slums are caused by several factors. for instance, urbanization and population growth has been recognized as the leading cause of slums (okafor and onuoha, 2016; yaode, 2019). the fact that urbanization and population growth contribute to slum prevalence suggest that slums can be described as areas that are heavily populated which shows attributes of substandard housing units and squalor. therefore, the ever-increasing nature of human population has made it difficult to combat with the corresponding development of slums in our urban environment especially in developing countries of the world. earlier, roy, lees, palavalli, pfeffer, and sloot, (2014) established that over half of the population of the world are living in urban areas. they predicted that by 2050, at least 7 out of every 10 human beings will be living in urban areas. while there are serious indications that urban population will increase sporadically, there appear to be no corresponding measures to provide housing units to accommodate the teeming and existing population. at present, most urban residents turn to informal housing and squatters for shelter due to issues relating to housing inaccessibility, increased house rent, acute contention for land/building use. due to the foregoing reasons, the urban poor have limited chances in accessing housing units with necessary facilities and amenities. specifically, the inability of the urban poor to comfortably afford housing with necessary facilities and in required standard is not unconnected to the increasing https://doi.org/10.56556/gssr.v1i1.310 http://www.jescae.com/ mailto:salvationeteng@gmail.com global sustainability research www.jescae.com 42 rental values which the urban poor and even the middle class in some areas are usually unable to afford. although there is slum prevalence in both developed and developing nations, the level at which slums are prevalent in developing countries outweigh it availability in developed nations. yaode (2019) reported that in 2001, there were 924 million globally. specifically, the figure suggest that 32 percent of the world’s total urban population are residing in slum. this figure therefore attest to the prevalence of slums in town and cities. equally in 2001, about 43 per cent of the combined urban populations of all developing regions and 78.2 people of those in least developed countries were slum dwellers. the situation is not different in nigeria. although statistics are inexact, current realities suggest that over 45 percent of urban residents in nigeria are slum dwellers. the figure is likely to increase especially due to inadequate attention which the housing sector is receiving coupled with the increasing poverty level in nigeria. clearly, urbanization and slum prevalence in our towns and cities have serious implications on city sustainability through creating diverse problems. for instance, urbanization promote alienation, traffic congestion, pollution, vulnerability, criminality and slum growth/prevalence. earlier studies (agbola and agunbiade, 2007; ola-adisa, enwerekowe and ella, 2015; yaode, 2019) have shown that there is serious criminality in slum prevalent areas. the increased level of crime is not unconnected to the fact that the residents of slum areas are economically disadvantaged and socially relegated. equally, slums are characterized with poor inhabitants that are delinquent in nature, hence crime is relatively on the increase in slums. most importantly, residents within slum areas are disadvantaged in terms of security. for instance, they are deprived of street lights while police protection is very minimal. all of these give a thriving ground for criminality at various levels. in calabar, evidences of slums abound in the city core. for instance, surveys within the study area has shown that residential districts such as akim neighbourhood, ikot ansa, ikot eneobong, mbukpa, henshaw town, cobham town, duke town and several other residential neighbourhoods are habouring slums. further observations during pilot surveys in the study area explained that residents within this slum prevalent areas are exposed to serious crime levels. therefore, criminal activities such as rape, robbery and stealing are increasingly high in the districts that have slums. from all indication, it is not out of place to recall that districts of poor housing environments are characterized with inadequate police protection, absence of street lights and other security gadgets which the residents of the slum prevalent areas are suffering tremendously from. from the foregoing, it is clear that slum prevalence has implications on crime incidences in calabar, nigeria. in spite of the fact that observations has made it clear that crime incidences abound in the study area specifically in slum prevalent areas, available studies have not been able to discuss the level of crime in slum areas, the specific causes and the effects that it has on residents of the area. furthermore, an understanding of the level in which slum prevalence and crime incidences inter-relate will be useful in guiding policies that will be useful in guaranteeing urban sustainability. although the term sustainability is highly contentious in it basic tenets, in this study, the term is used in understudying the level to which the environment can operate in such a way that slum prevalence will be minimized in spite of growing urbanization in the study area. most importantly, the study will contribute to existing knowledge as well as make policies that will stem the tide of slum prevalence and crime incidence in the calabar, nigeria. conceptual framework and literature review concept of sustainable development holistically, the concept of sustainable development of sustainability is very vital to the present study. the concept is underpinned in the use of available resources in such a way that the future would not be compromised. therefore, the basic tenets of sustainable development is the use of the resources and environment in such a way that the gains of future generations or the possibilities of future generations to make use of the environment will not be traded off. this suffice that the environment has to be used in such a way that the needs of the present generations will be achieved and future aspirations of generations will not be compromised. therefore, nkwocha (2014) suggested that sustainable development is a process of change in which the exploitation of resources, the direction of investment, the orientation of technological development, and institutional changes are all in harmony and enhance both current and future potentials to meet human needs and aspiration. sustainable development thus emphasis the activities channeled towards preserving the remaining resources and rehabilitating resources that have been treated carelessly in the past. in a broad sense, sustainable development emphasizes the provision of adequate and affordable basic needs of life such as water, forest and land for the present generation without jeopardizing the prospects of subsequent generations as well as the wise use of the environment to avoid deterioration. sustainable development planning sense is approached as the development of the environment in such a way that different land uses such as residential, commercial, residential and industrial would operate in such a way that each would not affect the prospects of the other. basically, the environment as an accommodating base is for facilities, infrastructure/utilities and municipal services as well as different land uses is expected to be managed in such a way that orderliness would be achieved. http://www.jescae.com/ global sustainability research www.jescae.com 43 the goal of sustainable development is to ensure that the needs of the future are not traded off. this supports what gbadegesin and aluko, (2011) considered sustainable development as a movement, a notion and an approach which has developed into a global wave of concern, study, political mobilization and organization around the issues of environmental protection. this is because of the indispensability of the concept in ensuring orderly environmental development and protection. sustainable development also reflects the attempt to achieve simultaneously the goals of an improved environment, better economy and a more just and participative society, rather than trading off any one of these against the others (ilesanmi, 2010). in addition, sustainability issues are considered to ensure that the potential negative significant impacts of development are not allowed to dispute the existence of others having in mind that the environment as an accommodating base is designed to harbour different kinds of activities, infrastructures and so on which should all co – exist in harmony (ogbazi, 2002; george, 2006). in his study, bamidele, bamidele and obaseki (2016) sees sustainable development as a socio ecological process characterized by the fulfillment of human needs while maintaining the quality of the natural environment indefinitely. he adds that if sustainable measures are not established, the environment would face drastic deterioration which would have several negative impacts on man’s health and well being. the concept of sustainable development is aimed at preventing resource waste through conservation, maximization of product utility and availability, minimization of environmental degradation and deliberately steering and directing actions and attitudes of resource producers and users towards the maintenance of safe, resilient, clean and healthy environment. nkwocha, (2014) further asserts that the achievement of the above and more sustainable strategies in the human landscape is ‘sine qua non’ for the realization of development. in town planning, sustainable development is used to bring lasting improvements in the economic, physical, social and environmental conditions of an area. this corroborates the submission by mbaiwa (2003) that economic viability, social acceptability, technical visibility and environmental compatibility are the key features of sustainable initiatives. in the light of the above, ibem, uwakonye and aduwo (2013) concluded that the adoption of the concept of sustainability of programmes is to ensure that specific social, economic and environmental needs of the present generation are met without compromising the potential of the posterity to meet their needs. with sustainability as a concept, it is evidently easy to ensure the orderly organization and development of our cities and towns without necessarily causing harm. the reasoning in sustainable development is to ensure that our environment is safe for human habitation and to check the adverse effects of emerging environmental problems which may be caused by parasitic, uncomplimentary and incompatible activities. from all indication, urbanization and population growth cannot be completely discouraged hence, slum prevalence and criminality is always at the verge of occurrence unless sustainable approaches are adopted in the management of our cities and towns. this imply that adoption of sustainable development as a concept in managing slum prevalent areas will seek for ideas to build channels of crime incidence prevention/protection without necessarily discouraging population explosion in urban areas. this can be done through encouraging economic diversity such that job opportunities will be maximized in urban areas. as expected, one of the leading causes of crime incidence and habitation in slums remain urban poverty hence, giving the economic standard of living adequate attention and expanding sources of earning livelihoods can create a balance between crime, slum prevalence and population growth. literature review slum development has become inevitable in urban areas due to the ever increasing number of persons that reside in cities together with the increasing demand for housing development and urban infrastructure/facilities. holistically, humans have attendant needs for housing since it is a major need of man (eteng, mfon and okoi, 2022). specifically, housing is ranked second only to housing in the daily needs of man sufficing that it is only food that tops in the chart of human needs (eteng et al., 2022). against this backdrop, the increasing number of people suggest a corresponding housing demand. more so, population increases more in the urban areas when compared to rural areas thus, slum development remains inevitable in urban areas due to the foregoing. although there exist several definitions of slums, salient features for defining slums include inadequate shelter, poor access to basic services, facilities and amenities and low quality of life (eni and abua, 2014). yaode (2019) regard slums as byproduct of the social and economic impacts of rapid urbanization. what constitute slums, it effects and characteristics differ according to scholars. for instance, yaode (2019) noted that slums are aftermath of migration which is inhabited by the urban poor. he explained that occupants in slums are usually constrained to choose such housing facilities due to poverty, inaccessibility to good housing facilities among other reasons. in his study on the analysis of slums in ilesa, yaode obtained data using questionnaire. his respondents were basically slum occupants which he systematically selected. his study revealed that slums in the core area are the product of inadequate housing, lack of timely maintenance of infrastructure and structures, poor environmental quality, environmental degradation, insecurity, disappointment with the unmet need for housing and social amenities. he http://www.jescae.com/ global sustainability research www.jescae.com 44 further showed that slums have negative implications on human health and comfort. with the observation that residents of the study area are faced with such menace, he suggested for urgent urban renewal in ilesa. he equally recommended the adoption of an integrated planning approach that can reduce rural poverty and improve urban livelihoods since these appear to be the main causes of slum growth in developing nations. in akure, omole and owoeye (2011) assessed slum characteristics of a deplorable residential district in akure, nigeria. their study adopted the tenets burgess’s planning model to describe the spatial distribution of land-use in akure with reference to investigating the factors that are responsible for slum formation and city degradation. they further examined the existing environmental situation in akure with reference to the housing system and the condition of infrastructure facilities. they further assessed the socioeconomic status residents of akure, their perception of the living environments and problems experienced using questionnaires observation, housing demographic and facility survey as instruments for data collection. their study showed a high degree of deplorable condition of living environments and the inadequacy of essential facilities for comfortable living. they also noted that the area was overcrowded with derelict buildings that lack basic household services. due to this, residents lack access to certain facilities and services. they therefore recommended the upgrade of the residential area. okafor and onouha (2016) in asaba, delta state observed that urban degradation is caused principally by urbanization process. they claimed that most of the environmental problems in asaba metropolis suburbs were due to unplanned land uses, swampy nature of built areas and weak development control. ekudayo et al., (2019) conceived that slums are heavily populated urban informal settlement characterised by substandard housing and squalor. they noted that slums are unavoidable in districts that are thickly populated without corresponding supply of housing units. they showed that slums are characterized by absence of good drainage system, sanitary system, refuse disposal and waste management, sources of water, standard buildings which make living very difficult for the people and also have negative effects on the housing quality of the dwellers within the area. they revealed that slums dwellers are exposed to unhealthy and unsafe environments. arimah (nd) opined that the proliferation of slums and informal settlements contribute to the enduring physical manifestations of social exclusion in african cities. arimah observed that slum dwellers are experiencing deplorable living and poor environmental conditions. due to the characteristic nature of slums, residents within such areas are excluded from participating in the economic social, political and cultural spheres of the city. this is due to the fact that basic facilities, services and amenities are lacking in such environs. arimah also observed that slums in africa are derived from low income level, no financial stability and absence of investment in infrastructure. however, he pointed out that the external debt burden of african countries, high levels of inequality, unplanned and unmanaged urban growth, and the exclusionary nature of the regulatory framework governing the provision of planned residential land are the indicators to slums and squatter settlements in africa. from the literature, it is obvious that slums abound in major cities and towns of the world. the causes and effects of slums are multifaceted. however, literature agree to the fact that slums derive largely from urbanization and increasing population. specifically, while people migrate, they do not move with houses implying that they demand housing units in their new areas of residence. inadequacies in housing supply which is occasioned by increasing housing demand without corresponding supply therefore make the situation grave. the situation is not different in the study area as increase in housing demand without corresponding supply brings about congestion in existing housing properties and facilities further resulting in deterioration and dilapidation of facilities implying that slum development becomes inevitable. this study therefore seek to address the issue. materials and methods study area calabar is the capital city of cross river state in nigeria. calabar is located between latitude 4⁰50’ north and 5⁰67’ north of the equator and at longitude 8 ⁰18` east and 8⁰26` east of the greenwich meridian. between 1882 and 1906, calabar served as the first administrative capital of nigeria. the city has been growing astronomically over the years. going by the population trend, the city had a total of 82,100 in 1975 while in 1978, the population had increased to 159,599. the total number of persons increase to 140,200 in 1985 and by 1991, the population was 217,800 320,862. the 2006 population census results put the total number of humans at 375,196 (agbor et al., 2022). the bulk of the population is made up of migrants from rural areas. migration into the city has become inevitable due to disparity in the provision of facilities and services of the area when compared to the adjoining rural areas. the people are largely engaged in commercial, industrial, educational and small scale farming activities. although urbanization is the main factor that trigger population growth in the study area, natural increase through birth rate also account for population growth. the increase in human population without corresponding provision of housing, infrastructure and facilities fast track the level of slum development in the study area. methods in order to obtain data for the study, 20 residential neighbourhoods in the study area that require renewal due http://www.jescae.com/ global sustainability research www.jescae.com 45 to slum prevalence were identified through reconnaissance surveys. from the 20 neighbourhoods, 10 residential neighbourhoods were randomly sampled out. the selection of 10 neighbourhoods represent 50 percent of the districts of serious slum prevalence in the city. in order to obtain relevant data from respondents. the population of the sampled 10 districts was obtained with reference to the 1991 population census results of the study area. according to the 1991 population census results, the sample areas had a population of 85,715. although the 2006 population census tend to be more recent, the 1991 population results were preferred. this is because in 1991, the population census was reported on the basis on neighbourhoods while the 2006 results were reported on the basis of local government areas. furthermore, the 1991 population census of the 10 samples areas was projected to 2021 using a growth rate of 3 percent which is the acceptable growth rate for projections in urban areas in cross river state (bassey, amba and eteng, 2021). the formular is given as follows; pn = po (1 + r 100⁄ )n equation 1 where; pn = projected population, po = existing population, 1 = constant, r = rate of growth (3%), n = number of years projected (30). the results of the projection showed that a total of 208,288 persons were residing in the study area by 2021. specifically, data were collected at the household level hence, to have a knowledge of the total number of households in the study area, the average household size of 6 persons was maintained which is the average household size in calabar (eteng and ajom, 2021). the exercise showed that the area comprised of a total of 34,715 households. therefore, there population of the study comprised of the total household size in the study area. obviously, the said population is too large and obtaining data from such a large population is unrealizable. therefore, a minimum sample was drawn from the entire population. to draw an appropriate sample, the taro yamene formular was used. the formular for the calculation is as follows; n = n 1+n(e)² equation 2 where; n = sample size, n = finite population e = level of significance (limit of tolerable error =0.05) therefore, n = 34,715 1+34,715 (0.05)² n = 34,715 1 +34,715 x 0.0025 n = 34,715 86.79 n =400 therefore the sample size for the study was 400. from the above calculations, 400 copies of questionnaire were administered to households in the study area. in order to deduce the sample from each neighboourhood that is, the number of questionnaire that were distributed in each neighbourhood, the number of households in each neighbourhood were divided by the total households and then, multiplied by the sampled household. table 1 consist of the population and sample households/number of questionnaire that were distributed in the study area. table 1: population and sample

46 from table 1, it is obvious that 400 copies of questionnaire were distributed at the household level in slum prevalent zones of the study area. specifically, the copies of questionnaire were systematically distributed using appropriate skipping range. various statistical approaches were used in carrying out analysis. specifically descriptive statistics such as frequencies and simple percentages. in order to establish the difference in the causes of slum development and it effect, the relative index (ri) was adopted. ri is mathematically represented as follows: ri = (5n5+4n4+3n3+2n2+1n1) /5n. the study adopted a fivepoint likert scale. the grading of the likert scale is as follow; 5 = very high, 4 = high, 3 = medium, 2 = low and 1 = very low. finally, slum prevalence was judged using certain criteria (variables) for housing quality. to this end, housing condition survey checklist was designed in order to understand the quality of the house and draw inferences on the level it is in the slum classification which was adopted in the study. a guide for scoring in order to determine slum prevalence in housing units was designed. as shown in the scoring guide, values were assigned to each option depending on the state of the houses/environment. the highest number in each of the options shown in the scoring guide was used in capturing data for the most suitable element under investigation. for instance, in appraising a house whose walls were intact/sound, 7 was recorded while a cracking wall had 2 and a dilapidating wall was given 1. this was replicated among all the options in the checklist. after each house survey, the outcomes averages were taken. any house/environment that scored from 50 and above was considered sound, those houses/environment that scored between 40 and 49 were graded as dilapidating house/environments while those that had below 40 were accepted as dilapidated houses/environments. the adoption of the scoring guide help a lot in deducing the prevalence of slums in the study area. the scoring guide is shown below; scoring guide (a) condition of wall (i) sound/intact = 7 (ii) cracking = 2 (iii) dilapidating = 1 total = 10 (b) condition of roof (i) sound/intact = 5 (ii) leaking = 3 (iii) sagging = 1 (iv) part missing = 1 total = 10 (c) toilet facilities (i) water closet = 6 (ii) pit latrine = 3 (iii) nearby bush = 1 total = 10 (d) ventilation (i) well ventilated = 7 (ii) poorly ventilated = 3 total = 10 (e) environmental conditions (1) drainage (i) free = 2 (ii) blocked = 1 (2) erosion (i) sheet = 2 (ii) gully = 1 (3) flood (i) not flooded = 2 (ii) liable = 1 (iii) flooded = 1 total = 10 the outcomes were summed to determine housing quality for instance, 7+5+6+7+6 = 31 50 = 62 the qualities of the houses were determined as follows; sound = 50 percent and above dilapidating = 40 to 49 percent dilapidated = 39 percent and below results and discussions table 1 shows the prevalence of slums in the study area based on certain criteria. as discussed in the methodology, the approaches for deducing the prevalence of slums was the use of housing/environmental condition survey. housing/environment that depicted dilapidating and dilapidation based on the scoring guide that was adopted were classed as slums. from the information as contained in table 1, slum prevalence in the study area is high. the prevalence of slums based on spatial locations explained that henshaw town with 82 percent drawn from the sample consisted of the largest number of slums in the study area. this is due to the fact that the area is in the city core and most of the landlords that own properties do not pay interest to upgrading/improving the structure. most of http://www.jescae.com/ global sustainability research www.jescae.com 47 the roles in the area are inaccessible while there is serious absence of infrastructure/facilities which are expected to contribute meaningfully to urban living. equally, the table showed that the prevalence of slums in efut uwanse and duke town is very high. the increasing slum prevalence in the area is not unconnected to poor city planning, absence of facilities to carter for the populace and associated issues. the table further explained that mbukpa and ikot ansa neighbourhoods constitute the least percentage of slums while slums are found at high levels in ikot ishie, ikot effanga, ikot eneobong, ikot omin and anantigha. in all, the observations in the table suggest that slums are prevalent in the study area based on different levels. the prevalence of slums basically constitute serious threat to safety, health and convenience of the residents of the area and even adjoining neighbourhoods. for instance, most residents within the area are deprived of potable water, waste management services while housing units that they are occupying are fast depreciating and deteriorating. 4.1 level of slum prevalence/housing quality s/n

the study area was shown in table 2. the table explained that crime incidences are occurring at various levels. specifically, respondents revealed that only 14 percent are not experiencing criminal activities. in most locations specifically in duke town, henshaw town and efut uwanse neighbourhoods, crime levels are increasingly very high. this is in line with the level of prevalence of slums in the area which is equally high. increasing crime level is also associated with poor security architecture and lack of technologies for mapping out crime and managing criminal activities in the study area. in most locations within slum prevalent areas, the roads leading to residences are less accessible and as such, it is difficult for police and other security operatives to embark on patrol. even more, streetlights in the metropolis are not functioning and there are no attempts by the government and it agencies to ensure repairs and maintenance of the streetlights. all these give rise to unwholesome incidences of criminal activities in derelict areas of functional obsolescence in the study area. it should be noted that one critical feature for defining slum is it lack of necessary facilities/amenities hence, criminal activities are likely to abound where the above and more facilities are lacking. table 2: level of crime incidence crime rate frequency percentage very high 92 23

provide detailed summary of causatives of slums in the study area based on ranks/levels. in order to understand vividly the variations in the levels/rank in terms of contribution to slum prevalence in the study area, the relative index (ri) was investigated using a 5-point likert scale indicating the levels. in all, it was observed that the major factor that promote slum development in the area was urbanization. through the process of urbanization, people leave their original places of abode and relocate for reasons such as availability of opportunities, facilities and amenities. in this case, residents in adjoining rural areas migrate to calabar. among the indicators to urbanization include the presence of the university of calabar, the cross http://www.jescae.com/ global sustainability research www.jescae.com 48 river university of technology, calabar, the school of nursing, college of technology and several government ministries and agencies all of which exert pull factors on rural residents. equally, calabar play host to the two largest markets (marian and watt markets) in cross river state which attract people for commercial activities. the negligence of government towards development equally pose challenges and promote slum prevalence for instance, the government are largely unwilling to provide community development facilities/infrastructure which has adverse negative effects on survivability and general environmental conditions of certain districts fast-tracking slum development. furthermore, poor funding for development of infrastructure, lack of partnerships and weak implementation of plans which all fall within the purview of poor funding contribute and stands as the 3rd causative factor for slums in calabar. the public which are the project beneficiaries in most cases do not maintain the few available facilities. sustainable approaches are not also adopted in tapping and harnessing resources which translate to unwise use of facilities that are made available for development in the study area. for instance, electricity supply materials such as cables and transformers experience loads that are above it carrying capacities based on the fact that the public continually mount pressure through extending the direction of electricity supply from such materials. the public do not also appear to be involved in adopting sustainable approaches to water supply systems, waste management systems, electricity supply systems and communication systems. even in houses of abode, some tenants are not interested in maintaining the housing units that they are inhibiting being that they are not the real owners of the properties. the above instances were noted to be the major causes of slums in the study area. table 3: causes of slums variables very

planning 43 88 54 31 184 2.4 5th source: field survey, 2022 effects of slums on the environment the effects of slums on the human environment are basically negative. for instance, table 4 noted that the major effect of slum prevalence in the study area was that slums provide hideout and habitation to criminals and thieves. as expected, house rent in slum environments tend to be affordable due to the fact that necessary facilities are lacking while the near absence of security operatives only aggravate the issues pointing towards providing hideout to criminals to promote and heighten incidences of crime within the study area. in the order of ranking, the foregoing tend to be the first in the effects of slum while general insecurity and urban/environmental decay tend to rank second and third respectively. the fact that environmental decay is an implication that is caused by the prevalence of slum suffice that there is need to ensure that the tide in which slums are evolving in out towns and cities need to be stemmed to the lowest. environmental/urban decay has serious implications on the general livability of residents within the area. housing shourtage which ranks fifth is also affected by the availability of slums and it prevalence within calabar metropolis. table 4: effects of slum on the environment variables very high high medium low very low ri rank hideout for

source: field survey, 2022 conclusion and recommendations the study focused on analyzing slum prevalence and crime incidences in calabar. it was observed that slums are prevalent and are found in alarming rate in the level. to deduce what constitute slums, both the environment and housing quality served as indicators. in all, it was observed that slums dominate in the core areas of the city due to http://www.jescae.com/ global sustainability research www.jescae.com 49 reasons bordering around urbanization, public attitudes towards environmental/housing maintenance and government negligence on towards facilities, infrastructure and amenities provision account for slum prevalence. poor planning and weak enforcements were also indicators to slum development and prevalence in the study area. the study further noted that due to the prevalence of slums, crime levels are high. in terms of spatial variations in crime, it was noted that slum prevalence and crime incidences were at par in neighbourhoods. this is due to the fact that when areas are deprived of certain amenities and infrastructure such as good roads and street lights, police patrol and other activities that can scare robbers become reduced to the minimum. street lights which provide illuminations further scaring robbers and hoodlums are mostly absent and when found, are not functioning. all this culminate into alarming levels of crime incidences in slum prevalent areas. based on the observations, urban regeneration measures were suggested. the best way to slow down the extent in which slums are evolving is the implementation of urban renewal programmes (ibem et al., 2013). it is therefore inferred that urban renewal plans be prepared while facilities/infrastructure that will support urban living be provided. there should also be slum clearance while site and service schemes should be introduced. furthermore, professionals should be involved in the planning, design and development of the area. these professionals should include town planners, estate valuers/managers, surveyors, engineers and architects. security should also given priority in slum prevalent areas of the city core.

turbidity and electrical conductivity fell within the permissible limits. the water was acidic because the mean ph value was lower than the permissible limit; dissolved oxygen was significantly low while biological oxygen demand was higher than the permissible limit signifying high load of organisms and impurities in the water. the total dissolved solid, ammonium, nitrate and sulphate were below the permissible limits. the mean values of fe, pb, zn, cr and co fell below the permissible limits. for cd, it’s dry season mean value was a little above who permissible limit but fell below fepa standard while the dry season mean value of mn was above fepa’s permissible limit but all of them fell within the who limit. however, industrial wastes disposed in this area have had adverse effects on the groundwater. therefore, adequate waste management method is one of the recommendations prescribed for a healthy and sustainable environment. keywords: groundwater quality; physico-chemical properties; heavy metals; permissible limits introduction water is one of the essential needs of man. security access to potable water supply is a central issue of concern not only in urban areas but much more in rural areas (atser and akpabio, 2015). the importance of water supply for domestic use cannot be compromised not only because of its social and economic values (atser and udoh, 2014), but also, because water based sources of livelihood have become critical to the survival and health of both urban and rural households, providing valuable contributions to them (bain et al., 2014). water is therefore a very strategic socio-economic asset especially in poor economies where wealth and survival are measured by the level of an access to water. access to water supply is therefore one of the key factors that enhance the well-being of the households (yange et al., 2013). in nigeria, water supply like in other developing countries is facing serious challenges many of which are economic and socio-political in nature (alayande, 2005). groundwater is one of the earth’s most widely distributed, replenishable resources. it is about 0.6% of the total global water resources and out of this, only 0.3% is being used for economic purposes (raghunath, 2007). in most countries, people depend on groundwater as the only source of drinking water because, groundwater is comparatively much clean and free from pollution than the surface water (mangukiya et al., 2012). contamination and over exploitation are the major reasons for groundwater deterioration (yadav et al., 2012). though recent years shift in usage from surface water to groundwater has controlled problems of microbiological and trace elements to a certain extent, but the same has led to newer problems of fluorosis, arsenicosis and salinity due to overexploitation of groundwater (singh et al., 2013). moreso, the extensive use of fertilizers, pesticides, discharge of industrial effluents, domestic sewage and solid waste dump, landfills and many other anthropogenic activities are the major sources of groundwater contamination mostly in the third world countries. this is rising day by day across the world due to extreme residential, municipal, commercial, industrial and intensive agricultural practices because the rate of discharge of pollutants into the groundwater is higher than the rate of purification https://doi.org/10.56556/gssr.v1i1.299 http://www.jescae.com/ mailto:umanaedo@yahoo.com global sustainability research www.jescae.com 15 (murhekar et al., 2012). therefore, it has become important to protect the groundwater resource against contamination in recent time, because it has negative effects on human beings, plants and animals (caliman et al., 2011; srinivas et al., 2011). above all, it is of great concern to act swiftly by carrying out this study since it may take years for the contaminated aquifer to be flushed out because of the rather slow flow (esu and amah, 1999). materials and methods study area the study was carried out at aka-offot industrial layout in uyo, akwa ibom state. it lies between longitudes 7° 55" e 7° 56" e and latitudes 5° 00" n -5° 01" n (figures 1). the area has a humid tropical climate with an annual rainfall ranging from 2500-3000mm and annual mean temperature of about 27°c and the relative humidity ranging from 75% to 79%. ikot ayan village, ediene is in ikono local government area of akwa ibom state, which was considered as a non-industrialized area was chosen as the control site. it lies between longitudes 7°45’e 8°00’e and latitudes 5°05’n -5°15’e (figure 1). the topography of the study area is low-lying with coastal plain sand as parent material (petters et al., 1989). the surface geology is unconsolidated sand formation ranging from coarse to fine sands (tahal, 1979; okoji, 1988). the soil is generally very porous and weakly structured with moderate nutrient and high water retention capacity, thus, the motivation in carrying out this study because of the fact that these boreholes which are sources of water supply to inhabitants of this area, are located within this industrial layout. methods of data collection with the aid of global positioning system (gps) and measuring tape for establishment of points, groundwater samples were collected from five (5) boreholes selected through simple random sampling method within aka-offot industrial layout, uyo during wet and dry seasons. water samples were equally collected from a borehole at the control site. the study sites were: (i) the nigerian security and exchange commission premises with field code (nsep), which is located 640 metres away from champion breweries wastewater disposal site and 905 metres away from plasto crown waste disposal site;

one for physico-chemical properties determinations, while the other one was for heavy metal analysis. samples collected for heavy metal analysis were preserved by adding a drop of nitric acid (hno3) after collection so as to preserve the metals. electrical conductivity, hydrogen ion concentration (ph) and temperature of the sampled water were determined at the field with the aid of the following equipment listed in table 1. the samples were stored in an ice-packed cooler kit and transported to the laboratory for prompt analyses within 24 hours, using standard scientific methods (table 1). results and discussion the results of the physico-chemical properties, and heavy metal concentrations of the water samples collected from the boreholes of the study area as well as the control site are presented in tables 2 & 3, for comparison with the control site and the world’s permissible standards (fepa, 1988 and who, 2006). physico-chemical properties physical parameters temperature the temperature of groundwater from the study area varied from 25.3 – 26.2°c with a mean temperature of 26.10°c while the control site had 25.2°c during dry season (table 2) and the wet season varied from 25.5°c – 26.0°c with a mean of 25.80°c and the control site had 25.0°c (table 3). the temperature of water from the study area for both dry and wet seasons was higher than the one of the control site. the temperature of water from the study area was slightly above the 25.0°c permissible limit of who (2006) and significantly below the 30°c stipulated by fepa (1988). temperature affects the amount of dissolved oxygen in water, metabolic rate of aquatic animals and so on. therefore, the temperature of water from the study area was slightly moderate. http://www.jescae.com/ global sustainability research www.jescae.com 16 turbidity the turbidity of water from the study area (mean) was 1 ntu during dry season and 1 ntu (mean) during wet season while the control site equally had 1 ntu for both dry and wet seasons (table 2 and 3). there was no significant difference between the turbidity values of the water from the study area, the control site and the world’s permissible limit of 1 ntu (fepa, 1988). high turbidity in groundwater is usually caused by particulate matter in suspension which results from land surface erosion. therefore, the average turbidity value in the groundwater of the study area was due to the fact that when water seeps downwards or percolates through the ground (mostly the coastal plain sands of the study area) most of the organic matter or suspended particles that are be picked near the ground surface have been gradually removed (esu and amah, 1999). this observation is explained by the “filtiplant function” of aquifers which states that “the unsaturated overlying an aquifers can act as a waste treatment system” (fetter, 1980; esu and amah, 1999). figure 1: map of akwa ibom state showing study area and control site. source: agate geographic services (2008) table 1: methods and equipment used for physico–chemical properties, nutrients and heavy metal analyses analytical equipment/ method of reference parameter cyberscan ph 20 meter ph cyberscan low 20 conductivity meter conductivity, temperature total dissolved solid (tds) microprocessor oximeter 196 dissolved oxygen (do) atomic absorption spectrophotometer (aas) (whitehead 1979, method) heavy metals spectrophotometrically by http://www.jescae.com/ global sustainability research www.jescae.com 17 (a) turbidimetry using baricum chloride (apha, 1993) sulphate, so4 (b) as nitrate after reduction in a reduction calcium system (parsons et. al., 1984) nitrate (no3) (c) formazine standards turbidity (ntu) (d) nesslerizaiton method ammonium (nh4) difference between initial oxygen concentration in sample and concentration after 5 days incubation in dissolved oxygen (do) bottles at 20oc (apha, 1993) biochemical oxygen demand (bod5) source: adapted from whitehead (1979);

wet season varied from 10-27 μs/cm with a mean of 20μs/cm from the study area and 15μs/cm for the control site (table 3). the ec mean value that of the control site, and equally the same situation during the wet season. however, the electrical conductivity permissible limits for groundwater were not supplied by who (2006) and fepa (1988). but from the tds values of water from the study area, the amount of dissolved salts in the water did not constitute any danger to human health and aquatic life implying that the electrical conductivity derived from the water of this area was in order (olasoji et al., 2015). chemical parameters ph the ph of water from the study area varied from 4.91-5.71 with a mean of 5.35 while the control site had 6.02 for dry season (table 2) and wet season varied from 5.16 – 5.91 with a mean of 5.54 from the study area and 6.08 for the control site. as indicated in the water from the study area, there was significant level of acidity as compared to the control site for both dry and wet seasons, likewise the world’s threshold standard of 6.5-8.5 ph for drinking water (fepa, 1988 and who, 2006). this range of ph may impair the potable state of groundwater from the study area. low ph and high content of carbon dioxide in water suggest that the natural state of water in such areas are corrosive to iron and steel and could attack carbonate minerals (esu and amah, 1999). dissolved oxygen (do) the dissolved oxygen of water from the study area varied from 3.0 – 3.20 mg/l with a mean of 3.10 mg/l while the control site had 4.5 mg/l for dry season and the wet season had 3.0 -3.1 mg/l with a mean of 3.0 mg/l for the study area and 4.7 mg/l for control site. the result shows that the do values of the water from the study area for both dry and wet seasons were lower than that of the control site. equally when compared to 5.0 mg/l recommended by who (2006) and 7.5 mg/l recommend by fepa (1988) for drinking water, implies that the amount

www.jescae.com 18 study area was significantly low; (low oxygenation) which could be attributed to the load of impurities and organisms in the groundwater occasioned by industrial effluent. this is also evident in the result of the biological oxygen demand (bod). biological oxygen demand (bod) the biological oxygen demand of water from the study had a mean of 0.2 mg/l while the control site had 0.05 mg/l for dry season and the wet season varied from 0.1-0.2 mg/l with a mean of 0.2 mg/l and the control site had 0.5 mg/l. the bod values from the study area were higher than that of the control site for both dry and wet seasons and significantly higher than the world’s permissible limit of 0 mg/l by fepa (1988) and who (2006) for drinking water, signifying high level of algae and other organisms in the groundwater with attendant decrease of oxygen in this water. total dissolved solid (tds) the total dissolved solid of water from the study area varied from 10.60-17.80 mg/l with a mean of 14.60 mg/l while the control site had 8.7 mg/l for dry season and the wet season varied from 5.8 – 14.7 mg/l with a mean of 9.40 mg/l from the study area and the control site had 4.8 mg/l. the tds values of the water from the study area were a bit higher than that of the control site but significantly lower than the fepa (1988) and the nigerian standard for drinking water quality (2015) permissible limit of 500 mg/l. total dissolved solid is a measure of the amount of dissolved salts in water. salty water conducts electricity more readily than pure water. the values of tds of the water from the study area indicate that the amount of dissolved salts in the water was not up to the level that constitutes danger to human health and aquatic life (olasoji et al., 2019). tds just like electrical conductivity, serve as tool for assessing the purity of water (united states environmental protection agency, 2022). ammonium (𝐍𝐇𝟒 +) the ammonium (nh4 +) content of water from the study area varied from 0.031 – 0.045 mg/l with a mean of 0.039 mg/l while the control site had 0.025 mg/l for dry season and the wet season varied from 0.031 – 0.041 mg/l with a mean of 0.036 mg/l and the control site had 0.023 mg/l (table 3). the mean contents of both dry and wet seasons from the study area were a bit higher than the ones from the control site but fell below the permissible limits of 0.2 – 0.3 mg/l by who (2006) and 1.0 mg/l by fepa (1988). ammonium is a source of nitrogen in water. there is need to control the way effluent is being disposed in this area to avoid water pollution from ammonium because its high concentration in water is toxic to aquatic life (olasoji et al., 2019). nitrate (no3) the nitrate content of water from the study area varied from 1.982 – 2.086 mg/l with a mean of 2.029 mg/l while the control site had 1.893 mg/l for dry season and the wet season varied from 1.980 – 2.081 mg/l with a mean of 1.890 mg/l and the control site had 1.890 mg/l. the mean content of nitrate in water from the study area during dry season was higher than the one from the control site while the mean value of nitrate in water from the study area, during wet season was the same with one from the control site but all of them fell below the 50 mg/l who (2006) permissible limit and 10.0 mg/l stipulated by fepa (1988). nitrate is a source of nitrogen in water but its high concentration causes excessive growth of algae and eutrophication in aquatic ecosystem (olasoji et al., 2019). sulphate (𝐒𝟒 𝟐) the sulphate content of water from the study area varied from 0.853 – 1.458 mg/l with a mean of 1.130 mg/l for dry season while the control site had 0.883 mg/l and the wet season varied from 0.824 – 1.433 mg/l and the control site had 0.798 mg/l (table 3). the mean contents of sulphate from the study area was higher than the ones from the control site but fell below the permissible limits of 400 mg/l by who (2006) and 500 mg/l by fepa (1988). sulphate is a source of sulphur in water, but its high concentration can impair photosynthesis and increase respiration (olasoji et al., 2019). heavy metal concentration iron (fe) the iron content of water from the study area varied from 0.042 – 0.182 mg/l with a mean of 0.104 mg/l while the control site had 0.025 mg/l for dry season and the wet season varied from 0.020 – 0.173 mg/l with a mean of 0.034 mg/l from the study area and 0.024 mg/l for the control site. the mean values of fe from the study area for both dry and wet seasons were a bit higher than the control site but fell below the permissible limit by 0.30 mg/l (who, 2006) and 1.0 mg/l for (fepa, 1988) for drinking water. lead (pb) the pb content of water from the study area varied from 0.0020.008 mg/l with a mean of 0.004 mg/l while the control site had 0.002 mg/l for dry season and the wet season varied from 0.001 – 0.004 mg/l with a mean of 0.002 mg/l from the study area and 0.001 mg/l for the control site. the mean value of pb for dry season was a bit higher than that of wet season but fell below the permissible levels of 0.01 mg/l (who, 2006) and 0.05 mg/l stipulated by fepa (1988). http://www.jescae.com/ global sustainability research www.jescae.com 19 zinc (zn) the zn content of water from the study area varied from 0.1050.343 mg/l with a mean of 0.207 mg/l while the control site had 0.043 mg/l for dry season and the wet season varied from 0.057–0.340 mg/l a mean of 0.192 mg/l from the study area and 0.039 mg/l for the control site (table 3). the mean contents of zinc from the study area were higher than the ones from the control site for both dry and wet seasons but fell below the fepa (1988) permissible limit of 1.0 mg/l for drinking water. cadmium (cd) the cadmium content of water from the study area varied from 0.002 – 0.007 mg/l with a mean of 0.004 mg/l while the control site had 0.002 mg/l for dry season (table 2) and the wet season varied from 0.001 – 0.003 mg/l with a mean of 0.002 mg/l and the control site had 0.001 mg/l (table 3). the mean concentration of cd in the dry season was higher than the one of the wet season. moreso, the mean values of cd in water from the study area for both dry and wet seasons were higher than the control site. it is observed that the mean cd value of 0.004 mg/l of the study area during dry season was above the who (2006) permissible limit of 0.003 mg/l but all of them fell below the fepa (1988) limit of 0.01 mg/l for drinking water. chromium (cr) the chromium content of water from the study area varied from 0.001 – 0.004 mg/l with a mean of 0.002 mg/l while the control site had 0.001 mg/l for dry season (table 2) and the wet season varied from 0.0010.002 mg/l with a mean of 0.002 mg/l and the control site had 0.001 mg/l (table 3). the mean values of cr in water from the study area were above the values of the control site for both dry and wet seasons but fell below the who (2006) and fepa (1988) permissible limit of 0.05 mg/l for drinking water. cobalt (co) the cobalt content of water from the study area varied from 0.011-0.038 mg/l with a mean value of 0.020 mg/l while the control site had 0.004 mg/l for dry season (table 2) and the wet season varied from 0.009 – 0.019 mg/l with a mean of 0.013 mg/l and the control site had 0.003 mg/l (table 3). the mean values of co in water from the study area were above the values from the control site. though the co permissible limit in drinking water was not supplied by who (2006) and fepa (1988), the value of co from the study area was the same with the united states environmental protection agency (2022) limit of 0.02 mg/l for surface water. manganese (mn) the manganese content of water from the study area varied from 0.014 – 0.073 mg/l with a mean of 0.33 mg/l while the control site had 0.013 mg/l for dry season (table 2) and the wet season varied from 0.009 0.061 mg/l with a mean of 0.026 mg/l and the control site had 0.009 mg/l (table 3). the mean values of mn in water from the study area were above the values of the control site for both dry and wet seasons but fell within the 0.4 mg/l permissible limit of who (2006) while the value from the study area during dry season was above the fepa (1988) limit of 0.05 mg/l for drinking water. however, strict measures in controlling wastes from this area should be applied. for instance, the implication for areas with high concentrations of fe2+ and mn2+ is that the waters will not only have taste but will stain laundry and plumbing fixtures and cooking utensils. incrustation of well screens and plugging of pipes are other adverse effects. apart from the problem of taste, manganese also enhances growth in reservoir filters and distribution systems (todd, 1980; esu and amah, 1999). conclusion/recommendations the study submits that the temperature of water from the study area was slightly moderate because it was a little above who permissible limit but below fepa limit. the turbidity of water from the study area fell within the permissible limit as well as the electrical conductivity. the water from the study area was acidic because the ph was lower than the permissible level. the dissolved oxygen in the water was significantly low which was attributed to high load organisms which equally manifested in the higher biological oxygen demand value which was above the permissible limit. this was attributed to high level of algae and other organisms with attendant decrease of oxygen in the water. the total dissolved solid of water from the study area was below the permissible limit as well as ammonium, nitrate and sulphate. in terms of heavy metals, the values of iron, lead and zinc fell below the permissible limits. for cadmium, it was observed that its mean value during dry season in the study area was a little above the who permissible limit but all of them fell below the fepa allowable limit. equally, the chromium and cobalt values of water from the study area fell below the permissible limits while manganese mean value of water from the study during dry season was above the fepa permissible limit but all of them fell within the who limit. in summary, some of the parameters of water from the study area were above the ones from the control site as well as the world’s threshold standards. it is concluded that industrial wastes from industries in this layout, have had adverse effects on the groundwater of this area. therefore, to safeguard the health and safety conditions of the inhabitants of this area and to operationalize a functional policy framework for industries in this industrial layout, the following recommendations are prescribed: the management of industries operating in this area should as matter of urgency, install anti-pollution equipment for the treatment of their effluent in line with fepa act (cap 131 of 1991), which states that “every industry shall install anti-pollution equipment for the detoxification of the http://www.jescae.com/ global sustainability research www.jescae.com 20 table 2: physio-chemical properties nutrients and heavy metal concentrations in water sampled from

march, 2023, published: 20 march, 2023 abstract background and objective: open defecation is the human practice of defecating in the environment rather than into a toilet. open defecation is a public health menace and causes health problems such as diarrheoa, typhoid, cholera, etc., in areas where people defecate places other than toilets or latrines. this study was aimed at determining the knowledge, perception and practice of open defecation among residents in ussa local government area of taraba state, nigeria. material and methods: a cross-sectional study design was adopted and used for this study. data were generated using a semi-structured questionnaire and an observational checklist. data generated were collated, synthesized and analyzed using spss version 20. results: the results obtained in this study showed that 260 (67.7%) had good knowledge of open defecation while 124 (32.3%) recorded poor knowledge. most respondents 202 (53.6%) demonstrated positive perception about open defecation while 182 (46.4%) exhibited negative perception. over two-third of the respondents 302 (78.6%) respondents indicated that they have defecated at least once in open space and only 110 (28.6%) have access to a toilet facility. perceived health problems associated with open defecation practice as indicated by the respondents were mainly; malaria 341 (88.8%), typhoid 221 (57.6%) and cholera 210 (54.7%). it was also observed that 274 (71.4%) households do not have a toilet facility, 200 (69.0%) lack access to improved source of water supply, 356 (92.7%) household lack a drainage system, 308 (80.2%) had bushes around their surroundings, 256 (66.7%) had odour of excreta in the surrounding and 239 (62.2%) lack a proper waste storage facility and exhibit poor waste disposal. conclusion: findings in this study showed that respondents had good knowledge and exhibited positive perception about open defecation, but majority of the proportion confirmed to have defecated in open fields. keywords: knowledge; attitude; open defecation; health implications; residents; ussa local government area introduction open defecation is the human practice of defecating in the environment rather than into a toilet. open defecation is a public health menace and causes health problems such as diarrheoa, typhoid, cholera, etc., in areas where people defecate places other than toilets or latrines (clasen, boisson, routray, torondel, bell, oliver, ensink, freeman, jenkins, odagiri, ray, sinha, suar, & wolf-peter, 2014). the term is widely used in literatures on water, sanitation, and hygiene (wash) problems in low-income countries. eradicating open defecation is the main aim of improving sanitation worldwide and it is an indicator used to measure progress towards the sustainable development goal (sdg6). irrespective of availability of toilets, behavioral change efforts on human is needed to promote the use of toilets. therefore, people need to be educated and convinced to desist from open defecation and use the toilets. the option of open defecation may be due to lack of access to toilets or cultural practices and these practices are common within countries where sanitation infrastructures are not available (clasen et al, 2014). ending open defecation would be an important public health intervention and success to healthy living (who/unicef, 2014a). it has been reported that extreme poverty and lack of sanitation facilities have been linked with open defecation. therefore, eradicating open defecation is thought to be an important medium to also eradicate poverty. this was due to the publication by the joint monitoring programme for water supply and sanitation (jmp) in their international year of sanitation (who/unicef, 2014b). open defecation is a common mailto:pharmalain2006@gmail.com https://orcid.org/0000-0002-0977-6919 global sustainability research global scientific research 11 example of poor sanitation. over the years, the number of people practicing open defecation has fallen by 21%, from 1.3 billion in 1990 to 1 billion in 2012 (who/unicef, 2019). these 1 billion people with no sanitation facility continued to defecate in gutters, bushes, bodies of water and open field, etc. most people (90%) who practice open defecation live in rural areas, but the number of people living in urban areas is also increasing (who/unicef, 2014a). according to world bank report in 2015, 39.84% of indian population practice open defecation and it is known as the country with the highest number of people practicing open defecation (who/unicef, 2014a). other countries with a high percentage of people practicing open defecation are indonesia (63 million people), pakistan (40 million people), ethiopia (38 million people), nigeria (34 million people), sudan (19 million people), nepal (15 million people), china (14 million people), niger (12 million people), burkina-faso (9.7 million people), (who/unicef, 2014a; (who/unicef, 2010). open defecation is influenced by a number of reasons which include lack of space to build toilets, lack of income, seasonal factors, and poverty. the major challenges faced by the residents in pursue to end open defecation is the lack of human resources base for sanitation. although people living in slums constitute the highest percentage of those without the access to toilets, the whole communities suffer the effect of open defecation (spears, 2014). open defecation is a serious public health threat to human health especially for children under five years. fecal-oral route is the major cause of diarrhoea disease as well as infections. open defecation was identified by the world health organization, (who) in the year 2014 to be the leading cause of diarrhoea deaths and a threat to human health globally, due to unimproved sanitation practices (who, 2013). it can also lead to malnutrition and stunted growth in children (spears, gosh & oliver, 2017). open defecation perpetuates the vicious cycle of disease and poverty and is widely regarded as an insult to personal dignity (who/unicef, 2014b). it causes serious harm when done in areas with high population or camping. with the insanitary situation in rural areas, open defecation has become a challenge and thereby an important public health issue and an issue of human dignity when it occurs in densely populated areas (o’reilly, 2016). about 1.1billion, people (15% of the global population) practice open defecation. on the 19th november, 2013, the united nations general assembly declared “world toilet day”, to encourage changes in both human behaviors and policies on issues ranging from enhancing water management, creation of sanitation facilities, to ending open defecation (afshan, 2013). research has also shown that the effect of open defecation is one of the most important factors of the groundwater sources pollution. the underground water is polluted when rain flushes feces that are dispersed in the environment into the water body (tamberkar & raigire, 2012). approximately, 46million nigerians (25% of the country’s population) practice open defecation, out of which, 33million live in the rural areas and 130million persons are using unimproved sanitation facilities and majority of those affected are rural dwellers (un, 2014). the eradication of open defecation is the key strategy for morbidity and mortality control, particularly in children under the age of five years (5). the general objective of this study was to assess the knowledge, perception and practice of open defecation among residents in ussa local government area of taraba state, nigeria. and the specific objectives were to: determine residents` knowledge of open defecation in ussa local government area of taraba state; determine residents’ perception of open defecation among respondents in the study area; determine the proportion of residents who practice open defecation in the study area; identify

implication on human health, dignity and the environment. it is mostly prevalent in third world countries including nigeria and significantly fuels the spread of infectious diseases, cause the proliferation of neglected tropical diseases (trachoma, schistosomiasis, intestinal worms, etc.) and increase cases of malnutrition especially amongst the rural populace (ngwu, 2017). ensuring an open defecationfree environment requires a strong synergy between the community and health professionals. in the light if this, understanding their perception about open defecation and identifying the factors influencing open defecation practice would be a perfect road-map to avert the practice of open defecation in nigeria. as documented in the current study, it was observed that two-third of the respondents 260 (67.7%) had good knowledge of open defecation especially in the aspect of defining open defecation, acknowledging that open defecation is harmful to human health and highlighting the possible effects of open defecation practice which include; emission of offensive odour, environmental degradation and pollution of water bodies (table 2). the exhibition of high knowledge level of open defecation among respondents could be attributed to their routine observation of events and practices within their environment, personal/family members/friends experiences and access to health promotion information. this finding was congruent with a recent ghanaian study where the study participants demonstrated high knowledge of open defecation (asare, gyan &denteh, 2019). more than half of the respondents 202 (52.6%) demonstrated positive perception about open defecation whiles the remaining 182 (47.4%) exhibited negative perception. respondents’ perception about open defecation may be influenced by their belief system, cultural practices, superstition, myths and religious affiliations. each of these perspectives may exert significant level of influence (whether positive or negative) on their level of practice. this suggests that interventions on achieving an open defecationfree environment should be tailored towards changing behavioural patterns of individuals who frequently practice open defecation. this finding was similarly reported by asare, et al. 2019, where respondents perceived open defecation as bad practice. however, it is worrisome where respondents in the current study believe that defecating on farmlands increases soil fertility and felt is beneficial to man and environment. this shows pure negligence of the effect of open defecation on human health. the low risk perception of the adverse effects of open defecation on human health may largely account for their negative perception towards open defecation practice. more than two-third of the respondents 302 (78.6%) indicated that they have defecated at least once in bushes, gutters, streams or uncompleted buildings, out of which 195 (64.6%) respondents frequently defecates in the open space (table 4). this finding was similarly reported in other studies but the percentage of open defecation was lower than that reported in the current study (verma, 2017; anuradha, dutta, raja, lawrence, timsi & sivaprakasam, 2017; panda, chandrakar, & soni, 2017). the high prevalence reported in the current study suggests that open defection is a common practice in the study area with a mix of lifestyle, culture and ancestral practices. open defecation tends to be more practiced in the dry season than during the wet season (table 4). the reason may be linked to the fact that wet season (especially during heavy rainfall) restrict or limit movement and operation of activities. as a result, respondents who do not have access to a toilet facility either defecate in a polythene bag or bucket and dispose it by throwing into the busy or in flowing water. in essence, dry season tends to be more favourable to practice open defecation than during wet season. it was also documented that only one-fourth of the respondents have access to a toilet facility and pit latrine was identified as the most type of toilet used. main reasons for not having access to a latrine/toilet as indicated by the respondents include; high cost of building an improved latrine/toilet, lack of enough space and some felt it’s not a priority (table 4).these reasons may be linked to respondents’ socio-economic status where the poorer population suffer most from lack of access to sanitation facilities. this finding corroborates with that of anuradha et al., 2017, where similar reasons for not having access to a latrine/toilet were documented. the significant lack of access to toilet facilities confirms the high prevalence of open defecation practices among respondents in the current study. factors influencing open defecation practice as indicated by the respondents were mainly; low cost, requires little or no maintenance, lack of access to toilet facility and convenience. this finding is congruent with other studies where similar factors influencing open defecation were documented (asare, et al. 2019; verma, 2017). contrariwise, a keyanian mixed-method study identified culture and poverty as major factors contributing to open defecation practice (busienei, ogendi & mokua, 2019). unlike the modern toilet facilities, defecating in open fields do not require any cost implication or any form of maintenance. this is often considered in households when building a latrine or toilet facility is less prioritized. lack of access to toilet facility has been identified as a contributory factor to open defecation practice. this was evident during the sanitary inspection of households conducted in the current study where only one-fourth of households had a toilet facility (table 5). in the light of this, communities and settlements without access to toilet facilities would continuously practice open defecation until a lasting solution is provided to address end this practice. even with the availability of toilet facilities, once the users outweigh the number of toilet facilities available, open defecation would still be practice. hence, adequate provision of toilet facilities can significantly curb open defecation practice. global sustainability research global scientific research 20 convenience as a factor contributing to open defecation could be linked to the fact that available toilet facilities is always dark, filthy, smelling, poorly ventilated and lack privacy. this was confirmed during the sanitary inspection of households where out of 110 households who had a toilet facility, toilet facilities in 52 households were unsanitary (table 5). the unhygienic conditions of some toilet facilities constantly encourage the practice of defecating in open fields. hence, while it is imperative to ensure the provision of toilet facilities for household use, effort should be tailored towards constructing user-friendly toilet facilities as well as devise an approach to ensure the toilet facilities is constantly in hygienic condition. perceived health problems associated with open defecation practice as indicated by the respondents were mainly; malaria, typhoid, cholera and dysentery (fig 2). this finding supports that of anuradha et al. 2017, where respondents knew at least one disease associated with open defecation practice. a number of health problems are largely associated with infected human excreta which contain several harmful organisms (saleem, buedett & heaslip, 2019). the identified health problems often affects a significantly proportion of the poorer population who do not have access to improved sanitation facilities (peprah, baker, & moe, 2015; njuguna & muruka, 2017). the diseases are usually transmitted via feacal-oral route which arise from consumption of contaminated agricultural food products and underground water sources. open defecation also propel flies and rodent infestation as well as emission of offensive odour which account for why malaria was the most identified health problem associated with defecation in open fields. regarding sanitary facilities and general surrounding of households, more than two-third of the respondents lack access to toilet facilities, improved source of water supply, drainage system, proper waste storage facility and exhibit poor waste disposal and had bushes and odour of excreta around their surroundings, (table 5). this results showed that a significantly proportion of the rural populace still lack access to basic sanitation facilities. lack of these facilities increases their vulnerability to contract infectious diseases within their vicinity and continually encourage the practice of open defecation. a healthy and open defecation-free environment can only be achieved if these sanitation facilities are adequately provided in rural communities. conclusion open defecation is still a common practice in rural nigeria especially where there is significant lack or limited access to improved sanitation facilities. the drive to protect human health and improve environmental sanitation would essentially require ending open defecation practice. findings in this study showed that respondents had good knowledge of open defecation, exhibited positive perception about open defecation, but majority of the proportion confirmed to have defecated in open fields. it was also observed that basic sanitation facilities in the study area such as toilets, access to improved water source, drainage system were not available in two-third of the household surveyed. hence, achieving an open defecation-free environment would require the collaborative effort of relevant stakeholders. acknowledgement: we acknowledge all our colleagues in the

effect on multiple organ dysfunction but pulmonary function is most affected area of a patients. pulmonary function or vital capacity have significance in the treatment of covid affected patients. vital capacity is defined as the maximal volume of air that can be exhaled from the lungs following maximal inspiration. present study aim is to compare vital capacity between covid-19 survivors and non-covid populations. a total of eight hundred fifty-nine (859) subjects of different ages have been selected for the present study. the present study data were collected by the multi-functional spirometer hi-801 for vital capacity, and the digital weighing scale was used for the measurement of body weight. the collected data was analyzed using descriptive statistics, the mean and the standard deviation (sd). an inferential statistically paired and independent t-test was applied to check the level of significance. the significance level was set at p<0.05. the results of this study, male covid survivors between the ages of 20 to 40 have better vital capacity recovery than male covid survivors over the age of 40, while female covid survivors between the ages of 20 to 40 outperform female covid survivors over the age of 40. female covid-19 survivors generally regain essential capabilities far more quickly than male survivors. we conclude that female covid survivors recover vital capacity much faster than male covid survivors. keywords: covid-19; vital capacity; multi-functional spirometer hi-801; recovery capacity introductions since its recent discovery, covid-19, also known as a coronavirus, has caused serious disruptions due to its rapid spread and high death rate in over 192 nations worldwide (huang. c et al.2020 & yang. l et al. 2020). the global coronavirus disease of 2019 was a pandemic caused by coronavirus 2 (sars-cov-2) (ren. s et al. 2020). the unique virus was discovered in an epidemic in wuhan, an eastern chinese city, in the last month of 2019. but wuhan authorities, specifically the chinese government, were unable to control the rapid progress of the fatal virus within the city. as a result, the virus spread throughout china before spreading globally (ren. s et al. 2020). pneumonia, severe symptoms of acute respiratory distress syndrome (ards), and multiple organ dysfunction are global sustainability research global scientific research 28 also common in patients with respiratory infections caused by covid-19, such as middle east respiratory syndrome (mers) and severe acute respiratory syndrome (sars) (huang. c et al.2020 & yang. l et al. 2020). investigations of pulmonary function or vital capacity have significance in the treatment of patients, particularly those who are covid-19 survivors who have suspected or been diagnosed with respiratory diseases (ranu. h et al. 2011) vital capacity can be measured as forced vital capacity (fvc), slow vital capacity (svc), and inspiratory vital capacity (ivc) (chhabra, s. k. 1998). vital capacity is defined as the maximal volume of air that can be exhaled from the lungs following maximal inspiration (tow, a. e. et al. 2001). as a general measure of overall pulmonary function, the assessment of vital capacity can be helpful in identifying a patient's ability to sustain adequate gas exchange without having to exert themselves excessively when breathing (tow, a. e. et al. 2001). the main drivers of individual variation in lung function include sex, body size, age, race, physical activity, and muscularity, in addition to other hereditary traits and present and past health (maiolo. c et al. 2003). the amount of vital capacity in an adult male is 4.8 liters and in an adult female is 3.1 liters. adult female lungs typically have between 10 and 12 percent less volume than adult male lungs of the same height and age (bellemare, f. et al. 2003). lung volumes increase steadily from birth to adulthood and the lungs mature at the age of 20–25 years, yet only minimal changes occur in the lung volumes over the following 10 years (sharma, g., & goodwin, j. 2006). aging is linked to gradual changes in lung sizes and other pulmonary functions beyond 35 years (zeleznik j. 2003). these changes include enhanced static lung compliance due to diminished alveolar elastic recoil and depressed chest wall compliance due to stiffening and increased outward recoil of the thoracic cage (mittman, c. et al. 1965 & janssens, j. p. et al. 1999). all the subjects gave their information, pulmonary function tests as they volunteered to participate in the study. the present study investigates covid-19 survivors 20 to 40 years old and above 40 years old, both male and female, vital capacity. the present study also found that non-covid 20to 40-year-olds and people above 40 years of age, both male and female, have vital capacity. the main aim is to compare vital capacity between covid-19 survivors and non-covid survivors' populations. methods a total of eight hundred fifty-nine (859) subjects of different ages have been selected for the present study. all subjects were living in their habitation, which is mixed by nature. some personal information, such as age, bmi, sex, nationality, size of chest, chronic disease, non-communicable diseases, types of profession, and types of covid-19 was collected. the present study data were collected by the wright pick flow meter (1960) for vital capacity, and the digital weighing scale was used for the measurement of body weight. using kolmogorov-smirnov and shapiro-wilks tests to scan the data and the data had a normal distribution (arafat, y. et al 2022). the collected data was analyzed using descriptive statistics, the mean and the standard deviation (sd). an inferential statistically paired and independent t-test was applied to check the level of significance. the significance level was set at p<0.05.descriptive and for comparison, appropriate inferential statistical tools (spss) have been used for the analysis of the gathered data on vital capacity. results in table number 1, a kolmogorov-smirnov and shapiro-wilks test (p >.05) and a visual inspection of box plots showed that the exam scores were approximately normally distributed for both samples, with skewness of 0.99 (se =.44) and kurtosis of 3.89 (se =.85) for the non-covid males 20 to 40 years old and skewness of 0.497 (se =.43) and

raised regarding the assessment of lung injury for released patients after the world health organization (who) classified coronavirus disease 2019 (covid-19) as a pandemic on march 11, 2020. covid19 has been linked to numerous lung injuries, and these injuries have been widely reported (mo. x. et al. 2020). pulmonary function includes vital capacity, and covid-19 impacts vital capacity (anastasio. f. et al. 2121). the maximum amount of air that may be exhaled after the maximum amount of inspiration is referred to as vital capacity (vc) (david. s. & sharma. s. 2019). according to the results of this study, male covid survivors between the ages of 20 to 40 have better vital capacity recovery than male covid survivors over the age of 40, while female covid survivors between the ages of 20 to 40 outperform female covid survivors over the age of 40. female covid-19 survivors generally regain essential capabilities far more quickly than male survivors. lung volumes increase at the age of 20–25 years, and after 35 years, there are gradual changes in lung volumes and other pulmonary functions (sharma, g., & goodwin, j. 2006. & zeleznik j. 2003). covid-19 is a harmful factor for all ages, both male and female, and especially the aging population is a big concern (david. s. & sharma. s. 2019 & shteinlukht, t. 2021). age is a major determinant in the development of internal organ and lung disease, and pulmonary disease has serious consequences for the aging population, according to previous research (lowery, e. m. et al. 2013). lung injury from covid-19 is associated with a decline in pulmonary function following an infection (anastasio, f. et al. 2021). global sustainability research global scientific research 33 the current study indicates unequivocally that females recover from coronavirus infections far more quickly than males. previous research has unmistakably demonstrated that women's immune systems are better able to fight off infections than men's (anastasio, f. et al. 2021& fink, a. l., & klein, s. l. 2018 ), and this is because of a structural genetic difference (pennell, l.m. et al. 2012). these findings imply that gonadal hormones might be involved in this sex disparity (clark. a. s. & goldman-rakic, p. s. 1989). in this instance, the findings of the current study are consistent with earlier work. regular exercise increases pulmonary function, a sign of vital capacity, and physically inactive people have lower vital capacities than physically active people of the same sex, age, height, and weight (taneja, s., & bose, j. 2021. & rong. c et al. 2008). only work and physical activity cause a variety of physiological changes in the body (panikulam, e. j. et al. 2016). the present study suggests that covid survivors and non-survivors exercise regularly in their daily lives because of a healthy lifestyle. the instruments used for collecting data were not of a very high standard, and time and finances were limiting conditions for the study. in future research, more subjects and standard instruments will be used. conclusion the finding of the present study is that the recovery phenomenon of vital capacity in 20to 40-year-old male covid survivors is better than that in above-40-year-old male covid survivors. the present study also found that 20to 40-year-old female covid survivors are superior to the above-40-year-old female covid survivors. in total, we conclude that female covid survivors recover vital capacity much faster than male covid survivors. acknowledgement: the subjects who contributed

(2021), the aforementioned would contribute to underproduction of food. the role played by banks in any economy together with agriculture cannot be undermined. it is against this backdrop that the study investigated the interaction of bank survival basu measured by z score, agroproduction (agpr) measured by agriculture, forestry, and fishing, value added (% of gdp) and capital formation(capf) measured by gross capital formation (% of gdp) and economic resilience (ecre) measured by per capita gdp growth in nigeria. for the purpose of the study the following research questions was raised: 1. does bank survival (basu) affects economic resilience (ecre) in nigeria? 2. does agroproduction (agpr) affects economic resilience (ecre) in nigeria? 3. does capital formation (capf) affects economic resilience (ecre) in nigeria? the research questions asked necessitated the following hypothesis in the null form: ho1: bank survival (basu) does not have effect on economic resilience (ecre) in nigeria. ho2: agroproduction (agpr) does not have effect on economic resilience (ecre) in nigeria. ho3: capital formation (capf) does not have effect on economic resilience (ecre) in nigeria. literature review conceptual framework bank survival and economic resilience banks enhance a country's monetary advancement by facilitating the pace of capital arrangement, money and credit, and satisfaction of financial goals needed for economic growth. access to finance is essential to set up a favourable atmosphere for the rate of development of enterprises. economic growth is the sustained increase in per capita national output or net national product over a long period of time (jones & ndubuisi, 2023a). the objective of facilitating economy growth would not be achieved if there are disruption in the provision of financial activities in the economy. hence the survival of bank operation is vital to the growth and development of any economy. ehiedu, onuorah, and mbagwu (2022) described commercial survival as means of achieving an organization mission and vision. agro-production and economic resilience when the production possibility frontier of an economy shifts outward it is said to be experiencing economic growth of which accumulates in a country’s resilience. jones and ndubuisi (2023b) asserted that economic growth is the increase in a country’s productive capacity . imene and udjo-onovughakpo (2023) opined that productivity in most firm has fallen as a result of recurrent conflict within an organization. imene (2023) also acclaimed that global sustainability research global scientific research 127 poor productivity and performance is as a result of inadequate evaluation system. as noted by tochukwu (2012), nigeria's economic future is not looking good due to the country's disregard for the agricultural sector and reliance on a monocultural economy centered around crude oil. in a similar vein, the agricultural sector is ideally situated to influence any country's pursuit of socioeconomic and industrial growth through its domains of activity at both the macro and micro levels. low productivity levels and the agricultural sector's sluggish growth are thought to be the primary reasons behind emerging nations' low incomes and sluggish economic growth (alston and pardey, 2014). gross capital formation and economic resilience any nation's gross capital formation is made up of expenditures that indicate increases to the economy's fixed assets as well as net changes in the amount of inventories. land improvements (fences, ditches, drains, and the like), the acquisition of plant, machinery, and equipment, and the building of roads, railroads, and similar structures, such as offices, hospitals, schools, and private residences, are examples of fixed assets. stocks of goods kept by businesses to accommodate sporadic or unforeseen swings in production are known as inventories (world bank, 2023). with adequate amount of capital, productivity of an economic would increase resultant in economic resilience of a country. empirical review gardner (2000) found a significant positive relation between the growth in the value added per agricultural worker and national gdp per capita. onuorah and ebimobowei in 2012 affirmed that accountability and public sector financial management enhance growth. spanos and lioukas (2001) contributed that the focus of performance has shifted from industry to firm specific assets . tsakok and gardner (2007) examined four distinct nations over four distinct time periods to investigate if agricultural development has consistently been a prerequisite for additional economic transformation of a nation. they come to the conclusion that economies can change and grow without the need for a sophisticated and modern agriculture sector. gollin et al. (2007) and self and grabowski (2007) contended that there is proof of a positive correlation between rising agricultural productivity and economic expansion. musah (2008) indicates that organizational performance should be measured through various indicators depending on the organizational structure. onuorah, arubayi and egbule (2020) stressed that employee relationship management has become imperative for competitive advantage and improves performance. existant literatures has showed that certain strategies should be applied by firms/ organisation to boast their return on assets which will also impact inclusive growth (onuorah, 2009; onuorah, 2010 ; anayochukwu & onuorah, 2016; ehiedu, onuorah & mbagwu, 2022). awokuse et al. (2009) used real export, agriculture value added per worker, gross capital formation per worker, and real gdp per capita as proxies in an effort to study the dynamic interaction between agricultural productivity and economic growth. they said that agriculture functions as an engine for economic development and is a key component of economic growth. people living in poverty can have better access to food and a better quality of life thanks to innovations in rural and agricultural finance (kloeppinger-todd & sharma, 2010). fatima, khan and arif (2017) opined that in emerging economies, the most influential side is the banking sector because banks providing the role of intermediary for trade and business transactions. qamruzzaman (2017) assessed the relationship between institutional innovation and economic growth of bangladesh and found that innovation either in a financial institution or financial market can influence economic growth. in order to measure organizational performance, rezaei et al. (2018) proposed using a variety of indicators, including both financial and non-financial measurements. finance is rooted on how well an institution uses financial assets to maximize value (osiegbu, onuorah & nnmadi, 2010; onuorah, 2011; osiegbu & onuorah, 2011). https://www.scirp.org/journal/paperinformation.aspx?paperid=104360#ref17 https://www.scirp.org/journal/paperinformation.aspx?paperid=104360#ref17 https://www.scirp.org/journal/paperinformation.aspx?paperid=104360#ref17 global sustainability research global scientific research 128 according to earlier studies (asaleye et al., 2020; kaya & kadanalı, 2022; onyiriuba et al., 2020), financing for agriculture increases productivity. while the disruption caused by cash shortages affected consumer and corporate moods, financial development (fd) can boost industrial activity (khemani & kumar, 2022; aroghene & imene, 2023). furthermore, green fd and green fd development (ed) have a positive correlation (sadiq et al., 2022). better financial systems are essential for effective economic growth (wen et al., 2022). some studies examined foreign direct investment, gross capital formation and trade openness as factors that determine economic resilience (dritsakis ,varelas and adamopoulos, 2006; erhijakpor & aroghene, 2023), of which was proxied by some researchers by per capita gdp (gardner ,2000; awokuse et al , 2009) while some studies proxied bank survival by z-score (aroghene & ikeora, 2022; aroghene, 2022a; aroghene, 2022b; aroghene, 2023c). from critical investigation of the aforementioned studies, each researcher used variables of particular interest and not all the investigation were done in nigeria using specifically the present study variables. this study filled the gap in literature by using specifically per capita gdp as the dependent variable and agriculture, forestry, and fishing, value added (% of gdp) and gross capital formation (% of gdp) to measure the independent variables. methodology in order to account for the interaction between bank survival and agroproduction on economic resilience in nigeria, the study employed zscore, agriculture, forestry, and fishing, value added (% of gdp) and gross capital formation (% of gdp) to measure the independent variables while per capita gdp annual growth rate was used to measure the dependent variable. time series data for nigeria was obtain from the world bank data base for the period of 2013 through 2021. different statistical analysis was carried out to investigate the influence of the independent variable on the dependent variable using the statistical package econometric views version 9.0. the study model is stated as ; ecre = f(basu, agpr, capf) eqn (1) ecre = b0+b1basu+b2 agpr+b3 capf+ut eqn (2) where; ecre = economic resilience b0 = the intercept basu = bank survival agpr = agroproduction capf = capital formation b1 b3 = the coefficient ut = the error term results and discussion the data for basu, agpr, and capf were obtained from world bank data base while ecre was obtained from macro trends.net are presented below; global

(2020), covid-19 has disrupted many industrial sectors, but the construction industry has been particularly hard hit. construction site employees and professionals are at a high risk of exposure to aerosol and droplet contamination as well as infection. the covid-19 crisis has stakeholders concerned about the construction sector's stagnation (gamil & alhagar, 2020). pathirana (2020) noted that because the virus prevented all humans from participating in any industrial work, the construction sector was initially targeted. according to bsisu (2020), the “restrictions placed on construction projects as a result of the pandemic crisis have slowed economic growth, increased unemployment, disrupted the supply chain for construction materials, and increased investment losses.” these effects are all due to the negative effects of covid-19. as a result, this year's growth in the construction industry has been reduced from 3.1% to 0.5% (global data, 2020). due to the corona virus pandemic, bangladesh's engineering industry is currently experiencing difficult times, including a decline in the economy, haphazard development efforts, and the loss of jobs for workers. according to financial express, the construction industry is one of the 15 sectors that contribute to bangladesh's gdp (gross domestic product). according to data from the “bangladesh bureau of statistics (bbs),” the construction industry made up 7.8% ($16.686 billion) of bangladesh's overall gdp in the 2019–20 fiscal years. in the event of employment, this is yet another massive sector that will generate job opportunities. according to the labor force survey, bbs (2017), the published that in the fiscal year, mailto:fahmida.chowdhury@yahoo.com global sustainability research global scientific research 23 2.1% of the total labor force was occupied in this sector, while it was 5.5% in the fiscal year 2017. supporting this statement, financial express (2021) reported that around 3.5 million people are concerned in this sector, of which 100,000 are directly engaged in various professional activities like architects, graduate engineers, diploma engineers, and other human resources. massive infrastructure development, including mega construction projects, has been undertaken by the country to become a developing country in 2026 (yeasin, 2021; aijaz et al., 2022). business standard (2021) published a report on the real estate and housing association of bangladesh, where the findings showed that this pandemic situation has delayed around 50–60% of the construction projects, caused a delay in finishing projects, increased the budget for materials, and raised the issue of a workers' shortage. as a result of the adverse impact on the national economy of this virus, 3.24% of the budget allocation for the ongoing megaprojects has been reduced in the 2020– 21 fiscal year (the daily star, 2020).for the engineering industry, determining the performance of engineering firms has become a research issue. the evaluation of a firm’s performance as assess of the company's excellence includes two major aspects: financial performance and non-financial performance. when discussing the company's performance, several researchers, including horta et al. 2018; tripathi & jha (2018) have focused on its financial performance. since such an appraisal is crucial for a company's owners, shareholders, and financial institutions because it clearly defines the company's true status, performance reviews of engineering companies can offer an assessment of the business’s operations. due to the drastic pandemic, the construction sector is facing massive uncertainty. the effects of the covid-19 pandemic on the world’s construction industry have drawn important attention for research since the construction industry suffered from project setbacks, labor shortages, job cutbacks, increased costs, and financial uncertainty as a result of this crisis (gamil & alhagar, 2020). several researchers have reviewed the effects of covid-19 on the construction industry in their study. gan and koh (2021) reviewed the precautionary activities taken by the legal authority such as government, labour organizations, and trade union to protect the labor rights and maintain the minimum wage rate. through a meticulous examination, al mansoori et al. (2021) found that the cost of labor and project prices is both increasing in the united arab emirates (uae) due to covid-19. like other countries, in bangladesh the pandemic has caused considerable delays in development projects across the country as the lockdown has limited both people and material supplies, causing many employees to lose their employment and others to be unable to work (dhaka tribune, 2022). according to a survey result, 90% of respondents felt that the pandemic was a curse on the construction sector, with roughly 51% of projects having partial stops and 40% experiencing total halts (prothom alo, 2022). furthermore, this pandemic is pushing some engineering and construction enterprises to consolidate debt, pursue other sources of funding, or face bankruptcy. the current study aims to investigate the before and after effects of the pandemic (covid-19) on the financial performance of bangladesh's listed engineering companies. the study targets all companies listed under the engineering category on the dhaka and chittagong stock exchanges. however, the main objective of this study is to examine the financial performance of listed engineering companies in bangladesh during the covid-19 pandemic. the main aspects of the engineering industry and covid-19's impact on it have been examined and cited with short descriptions. (a) to find out the significant determinants of the firm’s financial performance of listed engineering companies during the pandemic period. (b) to find out the impact of determinants on the firm’s financial performance of listed engineering companies during the pandemic period. in addition, this research has been following the structure where section two presents literature review, section three for methodology, section four for result analysis and discussion and section five for conclusion and recommendations. literature review wuhan, the capital of central china, was the first place where covid-19, a virus-borne infection brought on by the sars-cov-2 virus, struck. the world health organization (who) affirmed covid-19 a global pandemic on march 11, 2020. the social, economic, and health sectors were particularly hard hit, and researchers found that the covid-19 epidemic has slowed gdp growth and increased unemployment, inequality, and poverty nationwide (kumar & pinky, 2020; amin et al., 2021; ikram et al., 2021). the average gdp loss experienced by the 178 countries in the world as a result of covid-19 was 83,765.17 million dollars. on average, the economies of these nations would contract 16.04% of their total gdp, and on average, their economies would degrade by 7.67 years in 2020. the global recessionary phase began when the world's gdp shrank by 17.07% of its overall value over a seven-year period, reflecting a sharply declining trend brought on by covid-19. lockdowns, domestic tourism margins, air global sustainability research global scientific research 24 travel bans, unemployment, and changes in the human quality index as a result all had a negative impact on global economic growth (rahman & hossain, 2021; majumder & rahman, 2022). before covid-19, bangladesh had a dynamic economy partaking in an exceptional increase in neediness decrease, instructive fulfilment, orientation uniformity, and other financial markets that upheld this turn of events. the gdp growth rate in fy 2019–20 was only 5.24%, down from 8.15% the previous year. however, the engineering sector of bangladesh assumes an undeniably crucial role in the economy because of the progress of urbanization and a variety of huge framework projects attempted by the public authority. the development market is one of the 15 significant areas contributing to the gdp, and it includes projects such as infrastructure, transportation, trade and organization, energy and power plant development. the engineering sector posted 9.92% growth in 2017–18, up from 8.77% in 2017 and 7.50% in 2016–17. because of the increased emphasis on urbanization and the numerous infrastructure projects undertaken by the government, the development industry in bangladesh contributed to the pre-pandemic situation. there were also development projects undertaken by general individuals and individuals with a confidential interest in lodging, which contributed 9.6% to the development work. according to voumik et al. (2022), during the pandemic period, the progress of these ventures generally ceased, as well as other ongoing megaprojects being redacted at payra, maheskhali, and matarbari. bangladesh has undertaken a few megaprojects to lay out a prepared and unhampered correspondence network in the nation, including the “metro rail projects, the padma bridge, the passage under the karnaphuli stream, and the dhaka raised freeway from hazrat shahjalal international air terminal to the kutubkhali dhaka-chattogram thruway” which are likewise stopped in this emergency. however, the public authority takes different approaches to supporting the development work of activities impacted by the corona virus. alongside mega projects, the infrastructural development of bangladesh additionally relies on the land area, including different forward and reverse linkage businesses. the financial express (2021) revealed that the commitment by land area and alongside the forward and reverse linkage enterprises in gross domestic product was 8% of gross domestic product, while the gift goes up to 12–14%. however, because of the pandemic, this area took a gigantic hit during the primary lockdown, which caused devastation in the housing market. the obvious reason for this is that merchants began withdrawing properties from the market, anticipating lower costs, and property looking was dialled back and nearly slowed down as people became more concerned about their health security. the covid-19 pandemic forced the entire world to visage it, which inevitably led to significant changes in all regions, from economics to social (chen & yeh, 2021). every business sector and industry suffered as a result of the covid-19 epidemic on a global scale (brodeur et al., 2021). policies were implemented to reduce the impact of the covid-19 lockdown and social distancing measures (wang et al., 2020). khatib and nour (2021) saw that the corona virus pandemic altogether affects a few parts of business, for example, execution, administration, construction, liquidity, and influence level. shen et al. (2020) examined the effects of corona virus on organizational execution using financial data and discovered that corona virus had a negative impact on organizational execution. in india, das and patnaik (2020) found that different enterprises like telecom, the travel industry, avionics, the auto industry, and transportation are the most affected by the current crisis. various researchers examined the association between covid-19 and economic performance through their studies (goswami et al., 2021; debata et al., 2020). according to fu and shen (2020), covid-19 has had a significant negative impact on the performance of china's energy industries. “the listed companies' poor performance immediately following covid-19 may be attributed to organizational culture in dealing with challenges and crises.” according to forbes (2002), the company's financial performance may have been negatively impacted by the low income level of the population at the time of the pandemic. because of the extreme pandemic development, the area is confronting enormous vulnerability. according to the international monetary fund (imf), the global gdp will fall by up to 3% in 2018 due to the ongoing pandemic situation. the corona virus threatens a wide range of laborer occupations around the world. in the event of a pandemic, limited human development has had a negative impact on development efficiency as well as development firm execution, which unavoidably falls. to decrease the frosty impact of the corona virus pandemic, the government was compelled to stop numerous development projects. during this present circumstance, numerous enormous development organizations as well as little development organizations confronted financial misfortunes. jallow et al. (2020) showed that challenges in overseeing exercises, bringing about delays. in ghana, development projects experienced a decreased work rate, delays in instalments, and an expansion in material expenses during the global sustainability research global scientific research 25 pandemic time frame (agyekum et al., 2021). in india, alsamhi et al. (2022) found a massive contrast in complete pay, net deals, net benefit, profit per share, and weakened profit per share when the pandemic hit the travel industry, neighbourliness, and shopper areas. the review added that a massive distinction was made in complete pay-net deals when the pandemic was in developing and food areas, whereas there was no huge contrast between net benefit, profit per share, and weakened income per share when the pandemic was in building and food areas. besides, endrijatno and surjandari (2022) found that in indonesia, the pandemic condition didn't essentially influence the decrease in that frame of mind of the development organization, where the organization could make do with its capacities and keep up with its presentation. according to a survey response by 28% of individuals from the associated general contractors of america (agc), ventures in the united states were also delayed or stopped. a number of empirical researches have been demeanour to explore the impacts of covid-19 on different sectors in bangladesh’s economy. in light of both essential and optional information, islam (2020) concentrated on the effect of corona virus on the piece of clothing area in bangladesh, and found that because of corona virus, the piece of clothing area in bangladesh confronted a 3.18 billion dollar drop in orders, the store network of unrefined substances was seriously upset, and the products of the rmg area are 11.43% lower compared with the earlier year, but 72.4% lower than the earlier month in july 2020. this concentrate additionally added that the month-to-month development pace of the commodities in the rmg area was negative in fy 2019– 20. in her review, elahi and rahman (2021), rahman & dilanchiev, (2021) distinguished the eruption of the worldwide inventory network as the fundamental explanation that is seriously impacted by the time period. because of work in bangladesh, islam (2020) cantered that because of corona virus, the economy's development rate dropped sharply, causing the financial emergency and a large number of individuals lost their positions, all the more explicitly, 11 million positions were lost amid the time of lockdowns, and consequently, the economy suffered by 3% of the workforce losing their positions, of which a portion of 1,000,000 positions were looted. in his review, saha et al. (2020) saw the danger of joblessness because of the corona virus. the researcher discovered that the global and local economic downturns are to blame for a shortage of jobs in the clothing, transportation, travel industry, banking, security, and training sectors. on account of the rmg sector, the orders from worldwide purchasers were contracted, industrial facilities stayed shut, and laborers' contracts were ended. genoni et al. (2021) saw that the labor market in bangladesh, both at the broad and concentrated edges, including significant variety across regions and orientations, is impacted by the corona virus. at the same time, long-term outcomes of neediness, food security, and future income are also influenced by market laborers' long-term job losses. this pandemic is additionally connected with elevated degrees of vulnerability in the gig market, producing pressure and tension that might cause wellbeing and mental issues. observing the socioeconomic impact of covid-19 and its policy inferences for bangladesh pak et al. (2020) found specific sectors, including the leather, textile, and apparel sectors, have suffered reduced output, while agriculture product, manufacturing, services, and other sectors have been faced a reduction of output. the result is supported by other studies. during the period of the covid-19 pandemic, “garments and knitwear products, petroleum, cement, and other non-metallic mineral products declined sharply while drug and pharmaceutical products increased.” in addition, “the nominal wage rates in the industry and service sectors declined, the export of goods, imports of goods, and service payments had fallen, and the exports of the rmg sector had fallen largely due to the covid-19 pandemic” (hossain & alam, 2022). horaira (2021), sufian and hoque (2022) and nekmahmud et al. (2022) added that because of the pestilence, both domestic and guests dropped their visits, and many flights have been cancelled due to different travel limitations. therefore, organizations lose cash and laborers lose positions. according to mohiuddin (2020), the per capita daily pay of metropolitan slums and provincial poor has dropped by 80% as a result of the current countrywide closure authorized by the government, where a large portion of this population (40 percent to 50 percent) took credit to meet day-to-day expenses in bangladesh. once more, ali et al. (2021), elahi and rahman (2021), majumder and rahman (2022) concentrated on the effects of corona virus on bangladesh's economy, where he found that because of corona virus in bangladesh, the gross domestic product, trade volume, and settlements had a slump of 18.09%, 18.08%, and 19.73% separately, causing a downgrade of $40,984.34 million, $6540.97 million, and $3941.45 million in the year 2020, respectively, and this downturn went on for 3 years, 2 years, and 2 years from 2019 separately. once again, the global unemployment rate would rise by 1.38%, while in bangladesh it would rise by 2.43%. shahriar et al. (2021) saw that the corona virus caused an unfavourable effect global sustainability research global scientific research 26 on bangladesh's economy, which impacted the lives of a large number of individuals when their pay sources were hampered. furthermore, it was normal that the yearly misfortune of 53 million dollars was raised because the pace of the graduate joblessness rate expanded from 47% to 58% in 2020. ali et al. (2021) added that understudies at bangladeshi colleges have been experiencing unlimited mental stress side effects as the fear of academic postponement has progressed throughout the corona virus time frame. however, from the literature review, it can be said that existing studies focused on the impacts of covid-19 on the manufacturing, engineering, construction, and service sectors of bangladesh and the economy as a whole. in these studies, the researchers analyzed the effect of covid-19 on the financial performance of selected factors based on secondary data and explained it qualitatively. these studies are too narrow in scope to draw any firm conclusions about the effects of covid19 on a specific sector of bangladesh. because the urban informal economy, particularly the construction sector, has been severely impacted by covid-19, the urban informal economy is seriously affected by the lockdowns. as a result, this study was the first to examine the impact of covid-19 on the performance of listed engineering companies in bangladesh during the pandemic period. methodology of the study scope and data the study considers the engineering sector listed on the dhaka stock exchange (dse). the time period studied is 2019–2021. secondary data were obtained from the dhaka stock exchange website, journals, theory books, and so on. this study's cross-sectional unit is engineering firms listed on the dse. while the data used in this study is listed on the dhaka stock exchange and the chittagong stock exchange in 2018–2021, the company’s selection process used a simple selection process based on random process. the criteria used for selecting the cross section units are as follows: (a) selected companies listed on the dhaka stock exchange before 2019. (b) selected companies publish financial and annual reports on the dhaka stock exchange consecutively from 2019 to 2021. (c) selected companies are not delisting. (d) companies that provide complete data according to the required variables. variable justification and calculation process a. sales growth: the primary source of capital for the businesses is sales revenue. additionally, sales revenue affects the financial health of manufacturing companies (wamiori et al., 2016; rahman & majumder, 2021). b. liquidity ratio: current ratio is a “measure of relative liquidity that takes into account differences in absolute size. it is used to compare companies with different total current assets and liabilities”. current ratio can be measured by the formula: cr = (𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝐴𝑠𝑠𝑒𝑡𝑠/ 𝐶𝑢𝑟𝑟𝑒𝑛𝑡 𝐿𝑖𝑎𝑏𝑖𝑙𝑖𝑡𝑖𝑒𝑠) x 100. c. debt policy: debt policy is a choice made by the company's executive management regarding the amount of external funding obtained through debt as a source of command and control funding for the business (enekwe et al., 2014;

oskouei, 2019). creating a report that complies with “general accepted accounting principles (gaap)” requirements. financial performance can be measured by the formula. roa = (𝐸𝑎𝑟𝑛𝑖𝑛𝑔𝑠 𝑎𝑓𝑡𝑒𝑟 𝑇𝑎𝑥 /𝑇𝑜𝑡 ) x 100. generalized linear model (glm) multivariate regression analysis is important where we have used glm to see how the independent variables affect the dependent variable. an analysis known as multivariate regression analysis links the dependent variable to two or more independent variables (rahman et al., 2022; rahman & habib, 2021; majumder & rahman, 2020; rahman & majumder, 2022). to understand how the independent variable affects the dependent variable, use the glm regression analysis. equations 1 and 2's error terms' normal distribution was followed by the glm. μit = δ0 + δ1xit (1) yi ~n (μi, ε) (2) global sustainability research global scientific research 27 however, the econometric model of selected variables is presented in equation 3 to 5. fp = f(dr, gpr, lr, npr, sg) (3) fpit = δ0 + δ1drit + δ2gprit + δ3lrit + δ4nprit + δ5sgit + εit (4) lnfpit = δ0 + δ1lndrit + δ2lngprit + δ3lnlrit + δ4lnnprit + δ5lnsgit + εit (5) where i indicates cross unit, ε is error term, and the t is the time. ln= natural log for all the selected variables, fp = financial performance, δ0 = constant, δ1 to δ5 = regression coefficients, lndr = debt policy, lnlr = liquidity ratio, lnsg = sales growth, lngpr= gross profit ratio and lnnpr= net profit ratio. result analysis this study has considered several factors, such as debt policy, liquidity ratio, sales growth, and gross and net profit ratios, to measure the financial performance of engineering companies during the covid-19 period because those factors play a key role in ensuring the performance of a company. however, table 1 displays descriptive statistics results using several criteria, including mean, maximum and minimum value, standard deviation, and skewness with kurtosis value and sum sq. deviation. however, the estimated mean value of the variable lnfp is -2.55, the median value is -3.17, the maximum value is 2.50 with a minimum value of 8.08, the skewness is 0.34 with a kurtosis value of 3.24, the standard deviation is 2.37, and the sum sq. deviation is 264.37. the mean value of the variable lndr is 0.06, the median value is 0.09, the maximum value is 2.16, the minimum value is -2.28, the skewness is -0.27 with a kurtosis value of 2.94, and the sum sq. deviation is 44.01. the anticipated mean value of the data lngpr is -1.59, the median value is -1.54, the maximum value is -0.89 with a minimum value of -2.55, the skewness is -0.48 with a kurtosis value of 2.62, the standard deviation is 0.42, and the sum sq. deviation is 8.20. the estimated median value of the data lnlr is 0.41, the mean value is 0.46, the maximum value is 2.20, the minimum value is -0.86, the skewness is 0.81 with a kurtosis value of 2.62, the standard deviation is 0.55, and the sum sq. deviation is 14.26. however, the estimated mean value of the variable lnnpr is -2.92, the median value is 2.86, the maximum value is -1.45, the minimum value is -5.09, the skewness is 0.54 with a kurtosis value of 3.22, the standard deviation is 0.87, and the sum sq. deviation is 35.41. the anticipated mean value of the variable lnsg is -1.76, the median value is -1.89, the maximum value is -0.69 with a minimum value of -3.85, the skewness is -0.14 with a kurtosis value of 3.21, the standard deviation is 0.90, and the sum sq. deviation is 38.02. table 1: descriptive statistics of the variables lnfp lndr lngpr lnlr lnnpr lnsg mean -2.55 0.06 -1.59 0.46 -2.92 -1.76 median -3.17 0.09 -1.54 0.41 -2.86 -1.79 maximum 2.50 2.16 -0.89 2.20 -1.45 0.69 minimum -8.08 -2.28 -2.55 -0.86 -5.09 -3.85 std. dev. 2.37 0.97 0.42 0.55 0.87 0.90 skewness 0.34 -0.27 -0.48 0.81 -0.54 -0.14 kurtosis 3.24 2.94 2.62 5.32 3.22 3.21 sum sq. dev. 264.37 44.01 8.20 14.26 35.41 38.02 source: authors estimation global sustainability research global scientific research 28 table 2: correlation matrix among the variables lnfp lndr lngpr lnlr lnnpr lnsg lnfp 1 0.164 0.288 0.221 0.489 0.020 lndr 0.164 1 -0.325 -0.405 -0.050 0.221 lngpr 0.288 -0.325 1 0.551 0.478 0.119 lnlr 0.221 -0.405 0.551 1 0.339 -0.102 lnnpr 0.489 -0.050 0.478 0.339 1 0.252 lnsg 0.020 0.221 0.119 -0.102 0.252 1 source: authors estimation table 2 shows the correlation matrix, where the statistics show the correlation between the variables. there is some positive and negative correlation among the variables. lnfp and lndr, for example, have a positive relationship with a correlation value of 0.164;

this sign is expected for a company. however, the pandemic crisis did not hamper the maintenance of the relation between those variables, which is suggested by the accounting theories. table 4: results of generalized linear model (glm) variable coefficient std. error z-statistic prob. dependent variable: lnfp lndr 0.76 0.35 2.16 0.03 lngpr 0.80 0.95 0.84 0.40 lnlr 0.44 0.70 0.63 0.53 lnnpr 1.22 0.41 2.97 0.00 lnsg -0.44 0.36 -1.23 0.22 c 1.26 1.71 0.74 0.46 model fit evidences mean dep. var -2.55 s.d. dep. var 2.37 akaike info criterion (aic) 4.40 schwarz criterion (sic) 4.64 lr statistic 20.66 prob(lr statistic) 0.00 pearson ssr 177.20 pearson statistic 4.22 source: authors estimation table 5: confidence interval estimation of generalized linear model (glm) variable coefficient 90% ci 95% ci 99% ci low high low high low high lndr 0.76 0.17 1.36 0.05 1.48 -0.19 1.72 lngpr 0.80 -0.80 2.40 -1.12 2.72 -1.77 3.37 lnlr 0.44 -0.74 1.61 -0.97 1.85 -1.45 2.32 lnnpr 1.22 0.53 1.91 0.39 2.05 0.11 2.33 lnsg -0.44 -1.05 0.16 -1.17 0.29 -1.42 0.53 c 1.26 -1.62 4.13 -2.19 4.70 -3.35 5.87 source: authors estimation on the other hand, the independent variable, lngpr, has also had a positive impact on lnfp in engineering firms in bangladesh during the covid-19 period, and the estimated value of the coefficient is 0.80, indicating that a 1% increase in lngpr can enhance lnfp by 0.80 percent. there is a positive correlation between the variables lngpr and lnfs, which is a positive sign for a company. however, the pandemic crisis did not prevent the accounting theories from maintaining the relationship between those variables, such as lngpr and lnfs. the variables lnlr and lnnpr have a positive impact on lnfp in engineering firms in bangladesh during the covid-19 period, and the estimated values of the coefficients are 0.44 and 1.22, where lnnpr is significant at the 1% level but lnlr is insignificant. there is a positive correlation among the variables lnlr, lnnpr, and lnfs; this is strength for a company. however, the pandemic crisis did not global sustainability research global scientific research 30 prevent the accounting theories from maintaining the relationship between those variables, such as lnlr, lnnpr, and lnfs. the coefficient of the variable lnnpr is 1.22, which means a 1% increase in lnnpr enhances lnfp by 1.22 percent. however, the variable sales growth has a negative impact during the covid19 pandemic situation. in bangladesh, sales growth in the engineering sector faces a crisis because of the pandemic crisis, lockdown, and other restrictions. the coefficient of variable sales growth is negative to explain the financial performance, but this result is not significant. the model fit evidence shows no inconsistency, and the probability value of the lr statistic is significant at the 1% level when considering the minimum sic and aic criteria. in addition, the results of the confidence interval estimation of the glm model presented in table 5 consider 90%, 95%, and 99% intervals to justify the coefficient estimates and impact of the selected variables on the financial performance of engineering companies. conclusion and recommendation due to the fact that businesses can now be run anywhere in the world, financial performance is the main criterion used by investors worldwide. in order to fulfil commitments and accomplish the objectives set by the organization's top management, management used financial performance techniques. the share price and investor interest will significantly rise as the company's financial performance improves. financial performance gives investors and creditors crucial information they can use to decide whether to trust a company with their money. financial performance is one of many indicators that can be used to assess an organization's present state and future potential. the stakeholder must examine the factors that affect financial performance. management should be aware of the factors affecting a company's financial performance because it matters to both investors and internal stakeholders. financial performance measures the company's overall financial health, including the effectiveness of the top management's leadership. the covid-19 pandemic has negatively impacted the performance of many businesses and the economy as a whole in bangladesh. despite the fact that it experienced steady growth for the previous five years, the engineering sector is not immune to the recession. the goal of the current study is to determine how the pandemic (covid-19) has affected the financial success of some engineering sectors in bangladesh. all companies listed on the dhaka stock exchange in bangladesh are the subjects of the study. this study considered 40 engineering firms and analyzed data from the covid-19 period of 2019–2021. key findings during the covid-19 period indicate that lngpr has a positive impact on lnfp in engineering firms in bangladesh, and the estimated value of the coefficient is 0.80, indicating that a 1% increase in lngpr can increase lnfp by 0.80 percent. during the covid-19 period, the variables lnlr and lnnpr have a positive impact on lnfp in engineering firms in bangladesh, with estimated coefficient values of 0.44 and 1.22, respectively. lndr has a significant impact on lnfp in engineering firms, and the estimated value of the coefficient is 0.76, indicating that a 1% increase in lndr can boost lnfp by 0.76 percent. during the covid-19 pandemic, however, variable sales growth has a negative impact. since the financial performance of engineering firms during the covid-19 pandemic has not yet been examined in the context of bangladesh, the study is distinctive in that it does so. additionally, by examining bangladeshi sectors, this study offers useful insights to regulators and policymakers about the adverse effects on industries as a result of the pandemic. because covid-19 has had a major effect on sales growth, the authority should concentrate on maintaining that growth. government initiatives on domestic production and distribution would be a great addition to helping the country recover from this crisis. the key limitation of this study is the lack of updated data availability to compare post-covid-19 scenarios. a future study should focus on the total number of firms and the post-covid-19 evaluation of financial performance. acknowledgment: none funding: none declaration of interests: the authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. references agyekum, m. w., afrifa-anane, g. f., kyei-arthur, f., & addo, b.

(gcf, 2021) lao pdr is a landlocked country. but has much more natural resources than many asian nations, particularly in the areas of water, forests, and minerals. in 1940, the lao pdr had 70% of its land covered in forests, but by 2002, that number had decreased to 41.5% (undp, 2012), making lao pdr the 42nd most vulnerable country to climate change. one of these is phongsaly province in the north of lao pdr, which regularly experiences flash floods and droughts. lao pdr is thought to be the country most susceptible to drought. because rivers and streams are where most people reside. the primary industry is agriculture. (adb, 2012) according to the mekong river commission's (mrc) measuring station's observational monitoring data for the years 2020–2022, the phongsaly district experienced 40 droughts in total, including 9 severe, 5 extreme, and 1 catastrophic drought, the most of which took place between the july to december. (mrc, 2019) additionally, one of the sustainable development goals (sdgs), the 13th goal with a plan to address it, includes addressing climate change (climate action). in the scenario, it serves as a guideline for planning, mitigating, and adapting to climate change, as well as for resolving issues and creating a development plan for the lao pdr to lessen the effects of potential disasters like floods and droughts brought on by the worsening severity of climate change. additionally, it tries to adjust development strategies in accordance with the scenario and increase awareness of the severity of the issue. therefore, we are interested in using geographic information systems and models to analyze the places in phongsaly district and phongsaly province that have experienced floods and droughts because of climate change. literature review several studies have looked at global climate change issues, but in lao pdr, there are still few regional studies. phrakonkham, khasama, et al. (2020), integrated and mapped hazards using the analytical hierarchy process (ahp) across laos. from the results of the study, it was found that hazard areas are distributed in the northern and southern regions of lao pdr. rasanak, sanxay et al. (2021) studied the impact of climate change by using the cmip5 global climate model and rainfall runoff model to map flood hazard areas in the xedon basin in the southern part of lao pdr. from the results, the most high-hazard area found in the far future, the rcp8.5 scenario, covers an area of 483.9 km2. maisor et al. (2022) used the cmip6 global climate model by making a flood hazard map in the xechamphone basin in the central region of lao pdr. from the results of the study, it was found that in the near future, the ssp126 scenario has the most area of very high hazard, and in the near future, the ssp585 scenario has the most area of very high hazard. from earlier studies natural disasters and climate change continue to have an adverse impact on many regions. there is still no regional climate change analysis in the northern part of lao pdr, which is essential for planning mitigation strategies. methodology study area the capital of phongsaly province, phongsaly district, has a total area of 2,855 km2 and is located at latitude and longitude 208962 and 2419580, respectively, between (zone) utm 47 and 48n. it has a main river named nam ou and is the highest city in the lao pdr; its northern border is with china, its southern border is with xay district in oudomxay province, and its eastern border is with thailand. additionally, phongsaly district has a favorable climate for agriculture and produces agricultural goods. phongsaly district, phongsaly province, is reportedly one of the regions that has suffered disasters every year for the previous ten years or more, according to reports from various organizations. together with the issue of climate change that the world is currently facing. as a result, we decided to research this issue's consequences to develop guidelines for avoiding and lessening its negative effects. global sustainability research global scientific

and the far future from 2051 to 2100, and daily rainfall data for a 21-year period (1997-2017) was collected from four stations in the nam ou catchment area, namely phongsaly, muong ngoy, dien bien and oudomxay. refer to the data from the mekong river commission (mrc) rain gauge stations as shown in the table below. this historical data will be interpolated in an area with a resolution of 12.5 x

determine model accuracy or model performance. to estimate the desired value with the following formula: nse = 1 − ∑ (yi − yî) 2n i=1 ∑ (yi − y̅)2n i=1 where yi: the observed value of i when i is between 1 and n. yî: prediction value yi y̅: mean value of yi nse have a value between -∞ to 1 which can interpret the meaning of the nse value as shown in the table below: table 3. meaning of nse value. nse value model accuracy 1 perfect fit >0 <1 arithmetic mean 0 the model can predict the values as accurately as the prediction using the mean. <0 the model can predict with less accuracy than the mean estimate. ≥0.75 good prediction (yangqing lian, 2007) 0.36 – 0.75 satisfactory prediction (yangqing lian, 2007) kling-gupta efficiency (kge) this measure of fit was created by (hoshin v. gupta, 2009) to aid nash-sutcliff performance categorization analysis. this makes it easier to evaluate the relative significance of the variables (correlation, bias, and variance) within the context of a hydrological model (harald kling, 2012), whose equations are as follows: kge = 1 − √(cc − 1)2 + ( cd rd − 1)2 + ( cm rm − 1)2 where cc: pearson coefficient rm: average of observed values cm: average of forecast values rd: standard deviation of observation values cd: standard deviation of forecast values the pearson coefficient can be obtained from the equation below: r = ∑ (oi − o̅)(pi − p̅)n i=1 √∑ (oi − o̅)2n i=1 √∑ (pi − p̅)2n i=1 where oi: observation value pi: prediction value o̅: mean value of oi p̅: mean value of pi calibration large geographic resolution data are available from global climate models for precipitation forecasts. the data must be adjusted using linear scaling bias correction (ls) before using [9]. ls is a simple statistical estimating approach utilized in numerous investigations. phis(d) ∗ = phis(d) ∙ [μm{pobs(d)/{μmphis(d)}] psim(d) ∗ = psim(d) ∙ [μm{pobs(d)}/{μmphis(d)}] where pobs: observation data phis: historical data from gcms phis ∗: historical

precipitation data μm: correction factor return period to estimate the probabilities of total monthly rainfall and to estimate rainfall around the recurrence of total monthly rainfall in this research, we used a method (weibull, 1939) to obtain a frequency of exceedance that is closest to the mean value of the distribution, with the following formula: p = n (m + 1) where p: probability of exceedance n: total number of years record m: rank of observed rainfall value t: return period (mm) given by t = 1 p standardized precipitation index (spi) (thomas b. mckee, 1993) developed the spi method to determine and monitor climate drought conditions, which is now used by various organizations. it is widely used to analyze the spi index from monthly rainfall. the spi will be analyzed over 3 periods, namely 1 month, 3 months, and 6 months, which this research will define as spi_1, spi_6, and spi_12, respectively. spi = xij − xim σ where xij: precipitation for the station i month j (mm) xim: mean precipitation (mm) σ: standardized deviation the criteria used by the spi to categorize drought levels are listed in the table below: table 4. drought classification based on spi (mckee et al., 1993) drought classes spi ≥ 2 extremely wet (ew) 1.50 to 1.99 very wet (sw) 1.00 to 1.49 moderately wet (mw) -0.99 to 0.99 near normal (n) -1.00 to -1.49 severely dry (md) -1.50 to -1.99 severely dry (sd) ≤ -2 extremely dry (ed) flood hazard index classification by considering the flood depth of each square in the flood map and converting it to a value is a disaster index, we proposed the hazard level with a flood disaster index adjusted for the relationship between flood depth and velocity (sally j. priest, 2009), as shown in the table and figure below: table 5. flood depth-hazard index relationship. flood depth (m) hazard index small hazard < 0.3 0.00 – 0.25 medium hazard < 0.6 0.25 – 0.50 high risk < 2 0.50 – 0.75 very high risk > 2 0.70 – 1.00 global sustainability research global scientific research 7 figure 4. flood depth and hazard index relationship curve. results and discussions performance indicator using observed rainfall data from five stations in the watershed area and historical data from four gcms, a performance indicator was developed using nashsutcliffe and kling-gupta. from the result of the distribution of monthly rainfall with observed and simulated data, in most cases the simulated data is much less than the actual observed data, but in most cases the sample is close to the actual rainfall data. figure 5. scatter plot of observed and simulated

(2016) and islam et al. (2022), inflation can negatively impact macroeconomic performance because it disrupts the exchange mechanism. asako (1983) also found that inflation can cause slower capital accumulation during the transition under certain situations. apart from that, inflation adversely affects a country’s underprivileged population due to pricey groceries, commodities, and other necessities (rahman et al., 2022; elahi & rahman, 2021; rahman & habib, 2021; majumder & rahman, 2022). as the prices of essentials go up, so does the cost of living, causing suffering for most people. therefore, inflation control is one of the primary objectives of monetary policy in bangladesh. https://doi.org/10.56556/gssr.v2i1.441 mailto:ikramul@sfmu.edu.bd mailto:sidratul@sfmu.edu.com mailto:minhaz.uddin452@gmail.com mailto:sidratul@sfmu.edu.com global sustainability research 2 global scientific research the reasons behind inflation in bangladesh are multidimensional and dynamic here, both economic determinants and non-economic determinants such as the rule of law, control of corruption, and government effectiveness influence the rate of inflation (rahman & majumder, 2021; majumder et al., 2022; rahman et al., 2023; rahman & majumder, 2022; rahman & majumder, 2020). irregularities, unrest, and political instability can also cause inflation. for example, since economic determinants for inflation have always gotten more focus compared to the non-economic determinants, the rule of law, control of corruption, effective government, and other crucial factors were overshadowed despite having an impact on controlling inflation. as per coase (2005), economists did not even take into account the importance that lies between the economy and the state of law until recently. even though non-economic determinants like control of corruption and the rule of law positively affect economic growth (majumdar, 2022). hence, the impact of the rule of law, control of corruption, and government effectiveness on inflation is yet to be discussed broadly in the research field. therefore, to combat the adverse effects of inflation, maintaining a steady inflation rate while considering economic and non-economic determinants is now necessary. as per economists, a low-inflation environment accelerates economic growth. at the same time, a country also needs good governance for its economic development (grindle, 2012; rocha & jotty, 2022). and good governance covers non-monetary aspects like the rule of law, control of corruption, and government effectiveness (kaufmann et al., 2009). ensuring the rule of law, controlling corruption and government effectiveness will eventually affect a country’s economy, including the inflation rate. thus, in this study, these three key noneconomic indicators have been critically reviewed through general analysis and discussion to measure the impact they pose on inflation in bangladesh. no one is above the law in a society where the rule of law prevails. it ensures accountability of the government as well as obedience to regulation by the citizens, providing the rights guaranteed by the constitution of a country. the rule of law has a direct influence on sustainable economic growth, particularly for countries with years of monetary instability (barro, 1996; fischer, 1984). therefore, there is a good possibility that the rule of law can also influence economic growth indirectly by reducing the inflation rate to an acceptable level. as economists such as majumder and rahman (2020); dilanchiev et al. (2021) put importance on transactional rites and conviction as factors in the cost of production of goods and services, which depends on acquiescence with the rule of law. on the other hand, corruption is a threat to the state that hinders the efficient operation of the market. corruption occurs when public power is exercised for private gain. markets get out of control due to careless responses by corrupt businesses. corrupt business people are a small group of traders who want to create a monopoly, influence, and control over the market prices. they sell out or stock up on commodities with their syndicate. all these illegal practices in the market increase the price level. in this case, the government’s policies, commitment, and efforts to eradicate corruption can widen the scope for major investments, especially from foreign countries where control of corruption can influence inflation (braun & tella, 2004; uroos et al., 2022). according to the world bank (2021), government effectiveness means the government’s commitment to policies like public service, civil service, etc., and the implementation of such policies. it mainly depends upon the ability of a government to make democracy through intelligibility, accountability, and public involvement (kosac & fung, 2014). it builds people’s trust in the government. and that eventually leads to law enforcement and less scope for corruption, indirectly contributing to a reduction in inflation in the country. besides, the government can use a variety of policies and efforts to limit inflation, such as preserving law and order, ensuring effective resource allocation, resolving budget concerns, addressing trade deficits, etc. in addition, the government must limit the rate of population growth as well as the actions of middlemen to keep inflation under control. this study aims to provide and analyze empirical evidence of the impact of the rule of law, control of corruption, and government effectiveness on inflation in bangladesh, which will aid in the implementation of a low-inflation strategy. as a result, considering the legal aspects affecting inflation particularly alters the approaches to studying inflation factors in general, removing the difficulties of excessive reliance on abstract theory. however, given the importance of the study in the context of bangladesh, the influence of legal factors to ensure a stable economy with low inflation must be brought under the spotlight. the study adopted an analytical approach based on secondary data from world bank. however, the central focus of this study is to determine how non-economic determinants such as the rule of law, control of corruption, and government effectiveness influence inflation in bangladesh. the specific objectives of the study are as follows: to analyze the importance of the rule of law, control of corruption, and govt. effectiveness for economic stability and control of inflation. another objective is to measure the impact of the rule of law, control of corruption, and govt. effectiveness on inflation in bangladesh. the results can also be used to look into non-economic factors that contribute to low inflation and the creation of a well-organized legal system. as a result, the study makes an effort to assess how corruption, the rule of law, and government effectiveness affect inflation in bangladesh, which will give the body of literature a new perspective. the remainder of the section is divided into five sections: section 2, the literature review; section 3, the methodology global sustainability research 3 global scientific research section; section 4, the result analysis and discussion; and section 5, the conclusion and recommendation. literature review over the last decade, the factors of inflation have gotten a lot of attention. a lot of research has been done on the determinants of inflation. however, most of the studies were based on the economic determinants behind inflation. hence, this section of literature is focused on the three vital non-economic determinants of inflation, namely: rule of law, control of corruption, and government effectiveness, to identify the relationship and effect of these determinants on inflation. shevchuk et al. (2020) used annual data for the period of 2013 to 2019 of the rule of law index from the world justice project (wjp) for 40 countries. the estimates of cross-regression and panel data found a favorable anti-inflationary impact of the rule of law for the overall group of 40 countries. therefore, the rule of law can have a positive impact on reducing the high rate of inflation. again, according to acemoglu (2008), empirical evidence discovered that the impact of the rule of law on inflation is nonlinear, and the degree of public control over power may be an influencing factor in such cases, which must be taken into consideration. moreover, various research findings indicate that the central bank can take institutional decisions with a stronger anti-inflationary impact more independently when democratic institutions and the rule of law are present, as in bodea (2015), nurbayev (2018) and garriga (2020). as a result, it proves that there is a far-reaching consequence of the rule of law on inflation in a country. a study by inim et al. (2020) showed that in nigeria, other than money supply, inflation is also determined by other factors like corruption, government expenditure on security, political instability, etc. the word corruption is defined as “the abuse of entrusted power for private gain” and more often indicates the abuse of public office for private gain (gray & kaufman, 1998; rose-ackerman, 1999; lambsdorff, 2007; rahman et al., 2022; islam et al., 2022). on the other hand, mauro (1995) demonstrated that corruption has negative consequences not just on economic development but also on investments and the structure of official institutions, based on a study of 68 countries. according to braun et al. (2004), inflation variability can lead to higher corruption and less investment. in a sample of 75 economically significant countries, the study discovered a positive association between corruption and inflation fluctuation. as per the findings, a one standard deviation increase in inflation over the median increases corruption by 12% and decreases economic growth by 0.33 percentage points, which shows the influence occurs in both ways. according to piplica (2011), corruption increased inflation after the analysis of 10 transitional economies in central and eastern europe. yousefi (2015) used data from 164 nations between 1995 and 2010 to test her hypothesis that corruption leads to an increase in monetary expansion and, therefore, the inflation rate. for the overall sample, the study's findings revealed a substantial positive link between corruption and inflation. similarly, the findings of abed (2002), smith (2007), and samimi et al. (2012) are some who say that there is a positive relationship between inflation and corruption. as a result, necessary steps to reverse the increase in corruption must be taken to balance the inflation rate. in this association, becker (1974), mookherjee (1989), png (1995), besley (1993), and andreoni et al. (1998), among others, have given a theory that “control” can reduce corruption. thus, control of corruption can significantly reverse the effect of corruption on inflation. apart from the rule of law and the control of corruption, government effectiveness also helps maintain social equality as well as the economic growth of a country. as per kaufmann et al. (2008), the deciding variables of government adequacy are view of the nature of public administrations, the nature of common administrations, and the level of their autonomy from political tensions; furthermore, the nature of strategy planning and execution; and the believability of the public authority's obligation to such policies. hence, government effectiveness ensures proper distribution of resources through the implementation of policy, transparency, and accountability to gain the trust of the people. but, the absence of government effectiveness may lead to autocracy, resulting in inflation (adam & alhassan, 2021; raihan et al., 2022). as per bueno (2005), autocracies by nature depend on a small number of elites in whom political and economic resources are disproportionately concentrated. apart from this, khalid (2015) has used an econometric model to examine the short-run and long-run relationships between inflation and each of the important dimensions like government effectiveness, rule of law, and corruption control in pakistan. it was found that there existed shortrun as well as long-run relationships among the dependent and independent variables according to the engle-granger methodology. but, research on government effectiveness is still rare from bangladesh's perspective, which can prove beneficial to altering the high rate of inflation to a stable one. lastly, in the case of bangladesh, only a few studies have examined the role of determinants on inflation. for example, chowdhury (1995) notes that the inflationary process in bangladesh cannot be explained exclusively by the monetarist or the structuralism explanation of inflation, but it does have a strong but relatively short-run impact on inflation. hossain (2013) found that there is a positive relationship between money supply and inflation in bangladesh. uddin (2014) indicated that the gdp, money supply, and interest rates have contributed to increasing inflation in bangladesh. also, a few other studies have tried to examine the process of inflation in bangladesh on global sustainability research 4 global scientific research the economic determinants that affect the inflation rate, such as uddin et al. (2014), islam et al. (2022). however, the above studies are mostly focused on economic determinants and lack knowledge of the influence the non-economic determinants have specifically on bangladesh, without which it is difficult to explain how political instability, rule of law, control of corruption, government effectiveness, and other crucial determinants impact inflation. this particular study fills the gap in the literature by developing an empirical case of bangladesh that captures some of the necessary features that can lead to a robust change in how economists perceive inflation in an aspect of bangladesh’s economy. methodology model specification: generalized linear model the glm model permits us to fabricate a direct connection between the response and indicators, in spite of the fact that their veiled relationship isn't straight. this is made conceivable by utilizing a connection capability, which interfaces the reaction variable to a straight model. in contrast to linear regression models, the error dispersion of the reaction variable need not be regularly conveyed. the mistakes in the reaction variable are accepted to follow a thespian group of circulation (for example, normal, binomial, and other distributions). since we are attempting to sum up a straight relapse model that can likewise be applied in these cases, the name “generalized linear model” which was developed by nelder and wedderburn (1972) however, the functional form of this model is represented in equation 1. inflation = f(rule of law, control of corruption, govt. effectiveness) (1) inft =∝0+∝1 rolt +∝2 cct +∝3 get + ωt (2) for the simplicity of estimated model, log transformation is a necessary step. the log form of this model is presented in equation 3. ln(inf)t =∝0+∝1 ln (rol)t +∝2 ln (cc)t +∝3 ln (ge)t + ωt (3) where, ∝0 represent the intercept, ∝1 to ∝3 represent the coefficient of the estimation, ωt represent the error estimation tenure and t indicates time. the glm permits us to sum up a wide assortment of assessment results (le et al., 2020; liu & lu, 2018). the serious issue for the analyst who utilizes the glm is model detail. the specialist is liable for determining the specific condition that best sums up the information for a review. on the off chance that the model is miss-specified as well as small sample, the assessments of the coefficients such as ∝ values are probably going to be biased and the subsequent condition won't depict the information precisely. in complex circumstances, this model determination issue can be a serious and troublesome one. the glm is quite possibly of the main device in the measurable examination of information. it addresses a significant accomplishment in the headway of social exploration in the last couple of decades. adf unit root test since the purposes of time series analysis, recognizable augmented dickey fuller (adf) test is one of the most outstanding techniques for testing the unit root of a variable. in this cycle, the unit root has been analyzed by thinking about the slacked request of chosen factors and mistake or residuals assessments. stationarity tests permit checking regardless of whether a series has unit root problems or not. there are two unique methodologies: stationarity tests, for example, the adf test that considers as h0 that the series is nonstatiorany with the presence of unit root. ∆wt = β1 + β2t + τ(wt−1) + γt ∑ ∆wt−1 f i=1 + εt (4) where; εt are an error component and adf term wt−1 is the lagged order criteria, ∆ indicates the change and t presents the time. result analysis in table 1, the study of descriptive statistics shows that all the variables associated with this model are measured in terms of mean, median, maximum, minimum, standard deviation, skewness, kurtosis, jarque-bera, and probability. in the case of the measure of central tendency, it is estimated that the average of government effectiveness, inflation, control of corruption, and rule of law are-0.70, 5.58, -0.97, and -0.84 respectively. the average inflation rate, which is a dependent variable in this model, is the highest among the other variables. also, after sorting the observations, the median value of variables including ge, inf, cc, and rol is presented. the range, which is the dispersion, is presented by the minimum and maximum of the variables. moreover, st.dev, which shows how far each data value is from the mean, of ge and rol, is 0.11, which is the lowest compared to the other two values. it means that these values are more consistent and less spread out from the sample average. in addition, in the case of skewness, which measures the degree of asymmetry, it is seen that the values are positive except for control of corruption. in this table, ge shows normal skewness but not a symmetric or bell-shaped curve as it shows higher global sustainability research 5 global scientific research values towards the right side of the curve. also, inf, along with rol, shows normal skewness. moreover, cc shows a left-tail test in terms of skewness. with regards to kurtosis, which measures the flatness and peakness of the distribution, all variables, including inf and rol, represent lower kurtosis values, which are less than 3, except ge and cc, whose values are higher than 3. in this perspective, both variables like inf and rol have a platykurtic, which means more flat than the normal curve, whereas ge and cc have a leptokurtic, which means more peak than the normal curve. table 1: descriptive statistics criteria ge inf cc rol mean -0.70 5.58 -0.97 -0.84 median -0.73 5.69 -0.94 -0.83 maximum -0.43 8.16 -0.44 -0.64 minimum -0.86 3.26 -1.49 -1.02 std. dev. 0.11 1.47 0.26 0.11 skewness 1.16 0.09 -0.10 0.25 kurtosis 3.64 1.90 3.20 1.92 jarque-bera (jb) 6.07 1.30 0.08 1.49 probability (jb) 0.15 0.52 0.96 0.47 source: author’s inference table 2: adf unit root test results variables at level at 1st difference ln(inf) -1.85 -4.53*** ln(rol) -3.26 -5.90*** ln(cc) -2.92 -4.24*** ln(ge) -1.90 -5.19*** assumption: trend and intercept;

(2021). on the other hand, this study also found the fact that government effectiveness has a large impact on the control of inflation. this finding is similar to that of soh et al. (2021) and yousefinejad et al. (2022). in addition, this study also finds out the actuality where control of corruption has a hefty impact on control of inflation in bangladesh, which is supported by haider et al. (2011) for pakistan and ali and sassi (2016) for both developed and developing countries. conclusion and recommendations nowadays, inflation is one of the major concerns and challenges for bangladesh's economy. if the high inflation rate continues, it could pose an alarming situation for the economic development of a country. therefore, a stable inflation rate must be maintained by identifying and controlling the significant determinants of inflation. the preceding discussion demonstrates that, despite being overlooked, the rule of law, corruption control, and government effectiveness have a huge potential to influence the rate of inflation as non-economic determinants. thus, the impact of such crucial components must be studied in the case of bangladesh. this is an effective initiative for determining the impact and significance of noneconomic determinants on inflation in bangladesh. however, the unit root test indicates that i am stationary at the first difference of all variables (1). cointegration results ensure long-run association of variables. the glm technique is used in econometric methods to assess the importance of noneconomic determinants in controlling inflation. controlling inflation should be one of the government's priorities. the empirical studies mentioned above show that there is a significant long-run positive relationship between inflation and the rule of law, corruption control, and government effectiveness in bangladesh. since the study shows the rule of law has an anti-inflationary impact, more emphasis should be given to ensuring fundamental rights of people and civil and criminal justice through proper enforcement of law and regulations. the rate of inflation must be easier to keep under control in a country when the government executes the rule of law. moreover, corruption is the greatest threat to the government, and institutional reform is required to eliminate the breeding ground for corruption. political and economic restructuring should be carried out -15 -10 -5 0 5 10 15 2004 2006 2008 2010 2012 2014 2016 2018 2020 cusum 5% significance global sustainability research 7 global scientific research in tandem. and under a democracy, the government must be more careful to increase its effectiveness. because it is the right of people in a democratic country to criticize and question government actions, and it is the duty of the government to ensure accountability to the people. this paper highlights a new perception of how the inflation rate can be more effectively balanced by controlling regulatory and legal mechanisms, bridging the legal perspective gap between economists and legal and regulatory authorities. the analysis was limited by the small sample size, and further research may consider other macroeconomic determinants such as regulatory quality, political stability, and accountability voice, where those factors have contributed to lowering inflation in a country. acknowledgement: none funding: none author’s contributions: gmik, sm, mf and mmu and deals with substantial writing, theoretical analysis and revision. declaration of interests: the authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. references abed, george, t., hamid davoodi.

awodeae@futa.edu.ng received: 28 may, 2023, accepted: 18 june, 2023, published: 23 june, 2023 abstract this study explores the influence of p.juliflora leaves as an additive in the anaerobic digestion of poultry droppings from layers and broilers. six digesters (a, b, c, d, e, and f) were used with a retention time of 31 days. the dry weight content of the digesters include: 100% layer wastes (control), 100% broiler wastes (control), 95% layer wastes + 5% p. juliflora leaves, 90% layer wastes + 10% p. juliflora leaves, 95% broiler wastes + 5% p. juliflora leaves, and 90% broiler wastes + 10% p. juliflora leaves. layer wastes plus 5% prosopis juliflora created 18% more biogas than layer wastes alone, and layer wastes plus 10% prosopis juliflora produced 22% more biogas than layer wastes alone, which was the control set-up. in comparison to digester broiler wastes alone, broiler wastes plus 5% and broiler wastes plus 10% both produced 20% and 24% more biogas, respectively. in conclusion, adding 5 and 10 percent of prosopis juliflora to poultry manure from layers or broilers has significantly increased the generation of biogas. broiler wastes plus 10% prosopis juliflora yielded the most amount of methane and least amount of hydrogen sulfide, which makes it the most suitable substrate. keywords: biogas; renewable energy; digester; additive introduction the recent worldwide rapid population growth, along with the depletion of natural resources, has resulted in a significant increase in fuel prices. this has motivated a number of countries to investigate renewable and alternative sources of energy in order to fulfil their rising energy demands (ajiboye et al., 2018). reliance on traditional energy sources such as coal and petroleum has resulted in ecological imbalance, climate change, health risks, and resource depletion (aragaw & andargie, 2013). as a result, renewable energy sources such as solar power, biogas, biodiesel, wind power, and tidal power have emerged as the energy revolution's vanguard (islam, 2012). due to the continued use of fossil fuels and their associated environmental impact, particularly the influence of greenhouse gases (ghgs) on the environment, research focusing on the creation of alternative fuels from biological sources has expanded. carbon dioxide (co2) is the principal cause of growing ghg emissions in the atmosphere. notably, worldwide energy demand is continually increasing, with fossil fuels still accounting for around 88% of total energy output today (unep, 2014). anaerobic digestion (ad) is a promising, low-energy, and ecologically friendly technique. recent research has shown that biogas produced using ad has significant advantages over other bioenergy sources (nishio and nakashimada, 2007). when opposed to fossil fuels, ad technology can dramatically cut ghg emissions by utilizing readily available resources. furthermore, digestate, a byproduct of this method, is an ideal alternative to mineral fertilizers in crop cultivation. ad converts organic waste such as manure, food scraps, sludge, and agricultural leftovers into biogas in the absence of oxygen (iqbal et al., 2014). due to its minimal ecological impact (esposito et al., 2012) and great energy recovery potential (carrère, 2010), the ad process is preferred for transforming trash into fuel. biogas from ad has significant advantages over other bioenergy production technologies, and it has the potential to replace fossil fuels (ofoefule et al., 2010). mailto:awodeae@futa.edu.ng global sustainability research global scientific research 59 the anaerobic digestion of organic material produces biogas, which is mostly made of methane. because the anaerobic degradation process is comparable to the underwater decomposition of organic material in wetlands, biogas is sometimes referred to as “marsh gas” or “swamp gas” (iba, 2016). biogas is a colorless, combustible gas made up of 50-70% methane and 20-40% carbon dioxide, with traces of nitrogen, hydrogen, ammonia, hydrogen sulphide, and water vapor (lasisi and ojomo, 2017). biogas, a critical component of the carbon biogeochemical cycle, is naturally produced and can be used as an alternative energy source (energypedia, 2016). the current study seeks to assess the biogas yield of increased anaerobic digestion of two distinct breeds of chicken manure using prosopis juliflora. the study's objectives include: the design and construction of mediumsized digesters for waste decomposition, the analysis of the physio-chemical and microbiological properties of chicken droppings and prosopis juliflora, the evaluation of both the daily and overall cumulative yield of biogas, and the comparison of enhanced prosopis juliflora and nonenhanced biogas yield from various digesters. literature review despite the economic and environmental benefits of producing biogas from various biological wastes utilising ad technology, the search for more inexpensive, renewable, and sustainable energy sources is pressing due to rising fuel costs (fantozzi & buratti, 2011). the poultry sector is a major source of worry, as waste from daily chicken feed is frequently used as organic manure. with the growing number of chickens grown in nigeria, there is a pressing need to investigate alternate energy sources in order to mitigate the negative effects (ekka et al., 2016). several researchers have concentrated on producing biogas from a wide range of widely available agricultural and environmental wastes that are damaging to the environment (awode et al., 2022). although anaerobic digestion of biodegradable waste is thought to be a promising source of renewable energy, it has certain drawbacks. these include the slow decomposition of complex organic waste and the presence of carbon dioxide and hydrogen sulphide in the biogas produced (wang et al., 2023). before biogas can be utilized as fuel, these components must be eliminated. however, the introduction of prosopis juliflora during the anaerobic digestion process could significantly alleviate these restrictions, potentially increasing biogas generation while decreasing carbon dioxide and hydrogen sulphide emissions. prosopis juliflora (p. juliflora) is a nontraditional feed resource that has been investigated for its potential as an addition in the anaerobic digestion of poultry wastes. prabhu et al. (2021) evaluated the anaerobic digestion of several biomass wastes, including p. juliflora leaves, and discovered that p. juliflora pods produced the most biogas. samadi et al. (2022) studied the co-digestion of poultry abattoir and vegetable wastes and discovered that a c/n ratio of 25:1 was ideal for biogas production. however, no particular research on the effects of employing p. juliflora leaves as an addition in anaerobic digestion of chicken wastes were found. rajagopal et al. (2021) explored the combination of microalgae cultivation and anaerobic digestion of poultry wastes and discovered that the liquid digestate obtained after the digestion process may be used as a substrate for microalgae growth. the study employed various liquid digestate dilutions for microalgae growth and discovered that chlorella vulgaris cpcc 90 could grow and utilize nutrients from a 10% diluted chicken manure digestate. awode et al. (2022) evaluated the effect of biochar as a supplement on the anaerobic digestion of layer and grill poultry droppings. the biogas from the digester with the highest biochar content produced the most methane while creating the least hydrogen sulphide. according to the findings of this study, biochar can be utilized as a supplement to improve the efficiency of anaerobic digestion of poultry manure. hakimi et al. (2021) explored the co-anaerobic digestion of chicken manure with sawdust and local herbs such as serai wangi, peppermint, and orange peel waste as biogas additions. according to the findings of this study, traditional herbs can be utilized as supplements to improve the effectiveness of anaerobic digestion of poultry manure. as a result, the current study makes an important contribution to the body of information on improving biogas production from poultry waste utilizing prosopis juliflora. methodology materials the construction of the digesters was done with: six black plastic kegs of 25 l capacity each (they served as the main digester chambers), six catheter bags of 500 ml (was used to collect the biogas produced), flexible rubber hose (were used to connect the catheter bags to the digesters), 12.5 mm back nuts, stop corks, 12.5 mm pipes, pvc gum (all used global sustainability research global scientific research 60 for both the inlet and outlet of the digesters), thermometer, ph meter, weighing scale and syringe, (all used for various parameter’s measurement), and prosopis juliflora obtained from school farm are the waste to be used. digester design considerations in achieving one of the objectives of this research, some parameters were considered in designing and constructing effective and efficient digesters. the parameters include operating volume, digester volume and digester construction. they are briefly explained below. operating volume when a fixed amount of water is added to a known amount of feedstock, the operational volume of the digester is just the volume of slurry ratio in the digestion (babatola, 2008, ajiboye et al., 2018). for optimal digestion operation, it is common practice to use a digester whose total volume is less than the total volume of the slurry. according to ahmadu et al. (2009), the operating volume of a digester is determined on the basis of a chosen retention time and the daily substrate input quantity of the operating volume is expressed in equation 1. vo = sd × rt (m3/day × number of days) (1) where: vo is the operating volume of digester, sd is the daily substrate input and, rt is the retention time, which is the interval of time the mixed slurry is allowed to decompose in the digester. digester volume the volume of a digester is equal to the volume of the substrate container, whether the container is prefabricated or ready-made. the number of ready-made 25-l containers is what constitutes the digester volume in this case. the digester capacity, also known as the total volume, must be more than the operational volume to accommodate the expansion of the slurry and the creation of biogas during fermentation. slurry rise and biogas production require at least 20% of the total volume of the digester, which is why ahmadu et al. (2009) and otun et al. (2015) claimed that this volume should not exceed 80% of the total capacity of the digester. the total volume vt is thus given in equation 2. vt = v0 × 1.25 (2) digester construction each of the 25-liter containers had a hole drilled into its top and two holes drilled onto its sides. the top holes were roughly 1.5 centimeters in diameter. it was determined that a hose with an external diameter of 1.5 cm would be used to link the digester to the gas collection chamber (catheter), while a hose with an interior diameter of 0.9 cm would be used for this purpose. each keg had an additional hole cut in its base with a diameter of 4.1 centimeters; this hole served as the exit from which the slurry used in the ph measurement was drawn. each digester was outfitted with a thermometer that read daily temperatures. the entire biodigester system was made airtight by using rubber tubes and glue to seal any perforations. sourcing and collection of materials the digester component materials were all procured from oja-oba market in akure, nigeria. chicken manures for the two breeds (layers and broilers) were collected from the agricultural research farm of the federal university of technology, akure (futa), nigeria. pre-treatment of waste specimens these chicken manures were collected in black sealed polythene bags to preserve their original moisture. pretreatment was initiated at the point of collection, and it includes sorting, reduction in particle size and addition of water. pre–treatment is done to enhance degradation of volatile solids, thus increasing biogas yield. sample preparation and loading of digester the samples were prepared by mixing the manure of each chicken breed in varying component using 50:50 (10 l of water +10 kg of poultry waste) for control sample a and d, 45:5:50 (10 l of water + 10 kg of poultry waste + 1 kg of prosopis juliflora) for sample b and e, 40:10:50 (10 l of water + 10 kg of poultry waste + 2 kg of prosopis juliflora) for sample c and f. the composition of the mixtures is shown in table 1. the mixtures will each be loaded into the six 25 liters digester fabricated. thereafter, the set-ups were arranged well for digestion for 30 days. to ensure optimal digestion of substrate and to forestall the buildup of scum and layers that could kill off the bacteria global sustainability research global scientific research 61 and limit biogas generation, the digesters were manually agitated at regular intervals. each digester had a gas cylinder attached to its outlet, capturing the biogas it produced. result and discussions sample pre-analysis the analyses of the poultry waste consisting of the layer waste (lw) and broiler waste (bw) and their mixtures with prosopis juliflora in different ratios was carried out in the laboratory to determine their physico-chemical properties. table 2 shows the moisture content, volatile solid, total solid concentration and the different constituents of

average and cumulative biogas yield from the digesters the daily gas yield was measured and calculated through the difference in daily weight gain of the collecting bags and the increase in the weight gain of the bags. figure 1 and 2 show the graphs of the daily and cumulative biogas yield of the digesters, respectively. figure 1: daily biogas yield from digesters figure 2: cumulative biogas yield from digesters global sustainability research global scientific research 63 the different peaks and troughs located along figure 1 can be attributed to varying environmental and biological conditions of the different digesters. as observed in figure 2 the biogas production began on the first day of the retention period in all six digesters due to the extended pre-fermentation period and shows the biogas yield of the digesters over the 30-day retention period which started in small amount on the first day and increased steadily on the subsequent days till the peak yield was reached, and the yield started decreasing drastically until it finally stopped producing biogas, this reduction in daily gas yield is due to the fact that the microorganisms responsible for the production of biogas have consumed a large part of the substrate thereby leading to a drop in biogas production. this same trend was also noticed by kumar et al. (1987). from figure 2, for the layer wastes the cumulative yield of digester c showed an 18% increase from the yield of digester a and digester d showed a 22% increase from the yield of digester a while for broiler wastes, digester e showed a 20% increase in cumulative yield from digester b and digester f exhibited a 24% increase in biogas yield. figure 3: total biogas yield from digesters it could be seen from figure 3 that the highest biogas yield was from digester f for the broiler wastes and digester d for the layer wastes, but the broiler wastes had a higher yield than the layer wastes which may be due to the higher carbon to nitrogen ratio. figure 4: duration to reach maximum yield global sustainability research global scientific research 64 it could be seen from the figure 4 that when compared to the control set-ups a and b, the set-ups containing prosopis juliflora took a longer time to reach their maximum yields as was evident from set-ups d and f which could be due to availability of substrate for the microorganisms to feed on. figure 5: maximum biogas yield from digesters digester ph during retention period figure 6: ph of slurry in digester global sustainability research global scientific research 65 figure 5 shows that maximum biogas yield was observed to be higher in the digesters containing prosopis juliflora when compared to the control set-ups and was even higher in the substrates containing 10% of prosopis juliflora when compared to that with 5% prosopis juliflora which may be due to the higher carbon to nitrogen ratio. daily monitoring and comparison of the operating parameters digester temperature during retention period the temperature of the digesters was also recorded daily for the whole period of biogas production. the average ambient temperature observed during the study was 37 0c while the average digester temperatures for each of the five substrates digested were respectively 29.9 0c, 29.9 0c, 30.0 0c, 30.1 0c, 29.9 0c and 29.9 0c. these values show that there is negligible difference in the average digester temperatures for the six digesters, which provides a common base for comparison of results. the temperatures of the digesters fall in the mesophilic range and the ph falls within a range of 6.2 to 7.6 which is optimal for biogas production as reported by (aremu & agarry, 2013). the ph of the substrates was observed to have increased steadily as shown in figure 6 as the retention period increased from a slightly acidic to a more alkaline state as the acidogenic bacteria were displaced by the methanogenic bacteria to produce biogas. digester ph during retention period figure 7: average pressure in digester the pressure inside the digesters were also observed through the pressure gauge installed in the digester and were recorded daily at the point of collecting the gas global sustainability research global scientific research 66 collection bags. the average pressures of the six digesters are shown in the figure 7. analysis of operating parameters all analyses were done with microsoft excel 2016. regression analysis table 4: estimates of multiple regression analysis source ss

research 67 according to table 4, the cumulative yield decreases by 1.215 units for each change in the categorical variable waste type (e.g., from layer trash to grill waste). the waste type, duration ph, and constant (y-intercept) are the most significant variables in table 4.3, with p values less than 0.05. the relationship between the response and predictor variables is described in equation 4.1: cumulative yield = 0.57 ∗ duration + 1.975 ∗ percantage addition of pj − 0.245 ∗ temperature − 14.877 (3) biogas analysis from the experiment which was carried out, the highest biogas yields were recorded in digesters c, d and f. the gases produced from the 3 set-ups on the 10th, 20th and 30th day of the retention period were collected and taken to the laboratory for analysis of the constituents and the properties of the gas from the two samples. a shimadzu gc gas chromatograph mass spectroscopy instrument was used. from the table 5 it can be seen that the methane composition increases with time, the carbon (iv) oxide decreases with time and the nitrogen and hydrogen sulphide gas also decrease with time. the decrease in the hydrogen sulphide gas is responsible for the reduction in odor of the feedstock with time. the highest methane content was observed in the digester f i.e., broiler wastes and 10% prosopis juliflora on the 30th day but digester d showed the highest percentage increase in methane content; increasing by 13% from the 10th day to the 30th day and it is closely followed by digester f which shows a 12.28% increase. figures 8, 9, and 10 show the correlations between biogas production in digesters c, d, and f and the relative amounts of methane and hydrogen sulfide in the gas. figure 8: digester c (a) ch4 content & daily yield (b)h2s content & daily yield global sustainability research global scientific research 68 from figure 14 it could be noticed that in digester c the relationship between the daily yield and the methane content is positively correlated while the daily yield and hydrogen sulphide content are negatively correlated. figure 9: digester c (a) ch4 content & daily yield (b)h2s content & daily yield from figure 9 it could be noticed that in digester d the relationship between the daily yield and the methane content is positively correlated while the daily yield and hydrogen sulphide content are negatively correlated. figure 10: digester f (a) ch4 content & daily yield (b)h2s content & daily yield from figure 10 it could be noticed that in digester f the relationship between the daily yield and the methane content is positively correlated while the daily yield and hydrogen sulphide content are negatively correlated. discussions the objective of this study was to study the effect of adding prosopis juliflora in controlled proportions to poultry wastes, namely layers and broilers. from the preliminary tests carried out on the wastes, it was observed that broiler wastes had a lesser carbon to nitrogen ratio than the layer wastes and the substrates containing prosopis juliflora had a higher carbon to nitrogen ratio than the control set-ups. this shows that there is a relationship between the carbon to nitrogen ratio and the biogas yield, as reported by deublein and steinhauser (2011). biogas yield increased steadily from the time feedstocks were introduced until the third week, when it began to decline (possibly because microorganisms in the digester consumed the biodegradable part of the feedstock, causing the population of microorganisms to decrease, in turn decreasing the biogas yield (kossman et al., 2001). global sustainability research global scientific research 69 the highest biogas yields were recorded in the digesters using prosopis juliflora, with the layer wastes plus 10% prosopis juliflora digester producing 22% more biogas than the layer wastes only digester and the broiler wastes plus 10% prosopis juliflora digester. the biogas yield with the addition of prosopis juliflora was 24% higher than with just broiler wastes, corroborating what thanarasu (2019) found. after collecting and analyzing samples of gas on days 10, 20, and 30. it was determined that the methane content of the biogas increased with time. methane was found in lower concentrations in the gas on day 10, but at higher levels on days 20 and 30. sasse (1988) has also documented this. digester f achieved the greatest h2s reduction, by a factor of 32.8%. conclusion this project research revealed the amount of the gas that can be produced from the two types of poultry wastes (layer wastes and broiler wastes) can be increased by adding prosopis juliflora at different proportions to poultry wastes (layer and broiler wastes). according to the research, layer wastes plus 5% prosopis juliflora created 18% more biogas than layer wastes alone, and layer wastes plus 10% prosopis juliflora produced 22% more biogas than layer wastes alone, which was the control set-up. in comparison to digester broiler wastes alone, broiler wastes plus 5% and broiler wastes plus 10% both produced 20% and 24% more biogas, respectively. in conclusion, adding 5 and 10 percent of prosopis juliflora to poultry manure from layers or broilers has significantly increased the generation of biogas. broiler wastes + 10% prosopis juliflora produced the highest amount of methane and least amount of toxic gas i.e. hydrogen sulfide, which makes it the most suitable substrate. this study provided information on the quantity and quality of biogas produced from the anaerobic digestion of chicken manure mixed with prosopis juliflora through enhanced scheme and established the importance of prosopis juliflora in the codigestion of solid wastes for high biogas yield. acknowledgement:

0000-0001-9757-9730 received: 09 december, 2022, accepted: 25 december, 2022, published: 27 december, 2022 abstract singapore is a renowned tourist destination; however, the country's rapid economic growth has led to rising energy consumption and carbon emissions. this study aims to examine the factors that contribute to carbon dioxide (co2) emissions in singapore, including tourism, economic growth, and energy use. the dynamic ordinary least squares (dols) approach was used to analyze time series data from 1990 to 2020. the results of the empirical study revealed that the tourist coefficient is positive and significant. a 0.50% increase in co2 emissions relates to a 1% increase in tourism activities over time, according to the findings. in addition, the result indicates that the economy's long-run growth coefficient is significantly negative. this shows that a 1% economic growth will reduce co2 emissions by 0.03% in the long run. furthermore, a positive and statistically significant correlation for energy consumption suggests that a long-term increase of 1% in energy consumption is associated with an increase of 0.88% in co2 emissions. to promote the emergence of sustainable development and a low-carbon economy, this article proposed policy recommendations addressing the reduction of emissions and the promotion of ecologically responsible and sustainable tourism while boosting the utilization of renewable energy technologies. keywords: co2 emissions; sustainability; tourism; low-carbon economy; renewable energy introduction most greenhouse gases (ghgs) in the atmosphere are co2, and humans are responsible for most of these emissions. human activities that contribute to climate change include using fossil fuels for energy and cutting down trees (raihan et al., 2018; jaafar et al., 2020; raihan et al., 2021a; raihan et al., 2021b; isfat & raihan, 2022). co2 emissions are expected to have devastating effects on the global climate system and every area of human existence. due to atmospheric carbon dioxide sensitivity, the global climate system is quite sensitive. this is because climate change is expected to be one of humanity's biggest issues in the next decades (raihan et al., 2019; raihan et al., 2022a; islam et al., 2022). thus, reducing carbon dioxide emissions and enhancing the environment are two of the most critical global issues that must be tackled immediately to promote sustainable growth and mitigate climate change (raihan & said, 2022; raihan & tuspekova, 2022a). as a small, lowland city-state with one of the world's most open economies, singapore is especially vulnerable to climate change's negative effects (raihan & tuspekova, 2022b). singapore has ratified several international conventions to limit its carbon emissions and mitigate climate change. the kyoto protocol and paris agreement are examples of these conventions. as a result, understanding the main elements that affect co2 concentrations is crucial to improving singapore's environment. tourism, energy security, economic growth, and environmental sustainability are all crucial in southeast asian countries like singapore. if modern growth methods cannot be separated from natural resources, the ecosystem will degrade (raihan et al., 2022b). sustainable tourism is garnering global attention due to the direct, indirect, and induced economic effects of the tourist industry’s expansion. singapore, one of asia's most industrialized nations, relies heavily on tourism (katirciolu, 2014). singapore's economy also benefits from tourism. more than three times the country's population visited singapore in 2019. however, the tourism industry's key players' decisions are affected by its fragility. according to the unwto, worldwide travel will peak in 2030. because of this, global revenue is expected to reach $2 billion every year (raihan et al., 2022c). tourism boosts economies https://doi.org/10.56556/gssr.v1i2.408 mailto:asifraihan666@gmail.com global sustainability research global scientific research 54 worldwide (voumik et al., 2022a). however, tourism increases the need for energy to power transportation, accommodation, and support facilities, as well as food production and tourist site management, all of which can harm the environment (raihan & tuspekova, 2022c). the unwto estimates that tourism accounts for 5% of global emissions. seventy-five percent of tourism emissions come from transportation, while twenty percent come from accommodations (raihan & tuspekova, 2022d). as a result, when economy and transportation activities are included, the country's energy usage illuminates the link between tourism growth and co2 emissions (raihan & tuspekova, 2022e). tourism's importance in economic growth, particularly in singapore, has been ignored in emission models due to the idea that tourism drives economic growth. singapore has become one of the world's wealthiest nations due to its economy's rapid growth in recent decades. in 2019, singapore's gdp per capita was usd 61174, ranking third worldwide (world bank, 2022). however, whether unfettered economic growth harms the environment and generates enough cash to pay for environmental protection affects environmental development and sustainability plans. environmental development and sustainability plans will be rescinded if unfettered economic growth harms the environment (raihan et al., 2022d). conversely, the environment could be improving due to the economy's ongoing replacement of polluting technologies with cleaner ones (raihan & tuspekova, 2022f). because of this, assessing if singapore's economic growth is linked to environmental sustainability is one of the most important things to undertake. singapore's amazing economic growth is also linked to an increase in energy consumption and tourism. due to its various energy resources, fast industrialization, and rising tourism singapore's economy is one of the world's strongest. singapore's growing energy needs can only be fulfilled by burning a range of fossil fuels (mehmood, 2021). singapore's rising dependence on fossil fuels for energy has increased co2 emissions and degraded the environment. due to rising energy needs, as a result, there is widespread concern about rising emission intensity, especially in the energy sector. thus, climate change has exacerbated singapore's energy conservation debate. because of this, it is more important than ever to understand how tourism, energy consumption, economic growth, and co2 emissions are linked. however, despite the fact that the interplay between co2 emissions and their causes has recently been a prominent issue of discussion among researchers worldwide, only a small amount of research has been done in singapore. to fill this research gap, the present study used econometric approaches to examine the dynamic effects of tourism, economic growth, and energy consumption on singapore's co2 emissions. this study contributes to both the existing literature and singapore's policymaking process. to be more explicit, the current study fills a research gap in the academic literature by conducting a comprehensive econometric analysis of co2 and its determinants in singapore. the findings may give readers from diverse countries new ideas on environmental dynamics and sustainable management. time series statistical features and long-term correlations among determinants are shown in this study. the study's findings would provide decisionmakers with more complete and relevant statistics to establish successful policies in sustainable and environmentally friendly tourism, a green and low-carbon economy, and renewable energy development. these strategies may lessen climate change and carbon dioxide emissions. this research also aids in analyzing environmental laws and creating new ones. this will help singapore prepare for global warming's effects. the guidance may also reinforce policies and action plans to mitigate climate change, ensuring long-term sustainable development and environmental quality. the rest of the article is structured as follows. the

(2016) reported that economic growth and tourism positively influence co2 emissions in the panel of three diversified world regions including east asia & pacific, the european union, and high-income oecd and non-oecd countries. however, the review of empirical literature indicates that there is a scarcity of research on the relationship between co2 emissions and its determinants in the case of singapore, although it has become a hot topic among current researchers worldwide. therefore, the present study attempts to fill up the literature gap by investigating the dynamic impacts of economic growth, energy use, and tourism on co2 emissions in singapore. methodology data this study used the dols method of cointegration (stock & watson, 1993) because it may represent a continuous response variable as a function of one or more predictor components. it can be used to investigate experimental, economic, and environmental data and predict complex system behavior. singapore is a popular tourist destination, and tourism increases energy demand, co2 emissions, and economic growth. therefore, this study examined tourism, economic expansion, and energy consumption to determine how each of these factors affects co2 emissions. time series data on singapore from 1990 to 2020 were obtained from the world development indicator (wdi) dataset (world bank, 2022). to assure a normal distribution, the variables are logarithmically converted for estimation. after logarithmically transforming the variables, organizing the features into a bell curve with more conventional proportions improves model fit. this lets us depict data more accurately. table 1 lists variables, measuring units, logarithmic forms, and data sources. in addition, figure 1 shows the study variables' annual trends. table 1. logarithmic representations, units, and data sources of the variables variables description logarithmic forms units sources c co2 emissions lc kilotons wdi t international tourism lt number of tourist arrivals wdi y economic growth ly constant singapore dollar wdi e energy use le kg of oil equivalent per capita wdi global sustainability research global scientific research 56 (a) co2 emissions (b) tourism (c) economic growth (d) energy use figure 1. singapore's yearly trends for the variables studied source: world bank (2022) econometric strategies in theory, tourism contributes to pollution and higher co2 emissions, which in turn are linked to rising energy use and a growing economy. this research aimed to estimate the impacts of tourism, economic growth, and energy consumption on co2 emissions by plugging relevant data into the following equation (1) generated within the marshallian demand function (friedman, 1949) at time t: ct = ƒ (tt; yt; et) (1) moreover, equation (2) depicts the empirical model: ct= τ0 + τ1tt + τ2yt + τ3et (2) further, it is possible to use equation (2) as the econometric model in equation (3): ct= τ0 + τ1tt + τ2yt + τ3et + εt (3) where τ0 and εt stand for intercept and error term, respectively. in addition, τ1, τ2, and τ3 denote the coefficients. furthermore, the logarithmic arrangement of equation (3) can be expressed in equation (4) as follows: lct= τ0 + τ1ltt + τ2lyt + τ3let + εt (4) figure 2 depicts a flow diagram of the analytical procedures employed in the study to investigate the nexus between tourism, economic growth, energy consumption, and co2 emissions in singapore. 0 10000 20000 30000 40000 50000 60000 1 9 9 0 1 9 9 3 1 9 9 6 1 9 9 9 2 0 0 2 2 0 0 5 2 0 0 8 2 0 1 1 2 0 1 4 2 0 1 7 2 0 2 0 c o 2 em is si o n s (k t) year 0 5000000 10000000 15000000 20000000 25000000 1 9 9 0 1 9 9 3 1 9 9 6 1 9 9 9 2 0 0 2 2 0 0 5 2 0 0 8 2 0 1 1 2 0 1 4 2 0 1 7 2 0 2 0 in te rn at io n al t o u ri sm (n u m b er o f ar ri v al s) year 0 100000000000 200000000000 300000000000 400000000000 500000000000 600000000000 1 9 9 0 1 9 9 3 1 9 9 6 1 9 9 9 2 0 0 2 2 0 0 5 2 0 0 8 2 0 1 1 2 0 1 4 2 0 1 7 2 0 2 0 g d p ( co n st an t s in g ap o re d o ll ar ) year 0 1000 2000 3000 4000 5000 6000 7000 8000 1 9 9 0 1 9 9 2 1 9 9 4 1 9 9 6 1 9 9 8 2 0 0 0 2 0 0 2 2 0 0 4 2 0 0 6 2 0 0 8 2 0 1 0 2 0 1 2 2 0 1 4 2 0 1 6 2 0 1 8 2 0 2 0 e n er g y u se ( k g o f o il eq u iv al en t p er c ap it a) year global sustainability research global scientific research 57 figure 2. the flow chart of the analysis avoiding an incorrect regression requires testing the unit root (raihan & voumik, 2022a). first, differentiate the regression variables, then estimate the desired equation using stationary processes. this ensures the experiment's variables won't change (raihan & tuspekova, 2022h). in the empirical literature, the sequence of integration must be understood before determining cointegration. when defining the integration order of a series, several unit root tests are needed because their power depends on the sample size (raihan & tuspekova, 2022i). the current study used dickey and fuller's (1979) augmented dickey-fuller (adf) analysis, the df-gls test proposed by elliott et al. (1996), and phillips and perron's (1998) p-p unit root test. these tests were aimed to find the autoregressive unit root (raihan & voumik, 2022b). in this study, the unit root test confirmed that no variable surpassed the order of integration and supported the dols methodology as an alternative to cointegration methods. this study used dols to analyze time series data that includes initial difference term leads and lags. it also considers variables that explain outcomes. this is done to preserve endogeneity and compute standard deviations using a serial correlation-free covariance matrix of errors. this ensures data accuracy. the dols method ensures that the predicted standard deviations were calculated correctly (raihan and tuspekova 2022j). the dols approach shows that the incorrect term has been orthogonalized by considering the words before and after each term. this can be achieved by comparing leading and trailing terms. the dols test can assess statistical significance as the dols estimator’s standard deviations follow a normal asymptotic distribution (raihan and tuspekova 2022k). the dols method incorporates individual variables into the cointegrated framework in mixed-order integration. this can be done by estimating the dependent variable's value with respect to the explanatory components' levels, leads, and lags (raihan et al., 2022e). the dols estimation's main strength is its cointegrated outline, which includes individual integration variables of a mixed order (raihan et al., 2022f). in the dols technique of estimating, one of the i (1) components was regressed with the other variables, some of which were also i(1) variables with leads (p) and lags (-p) of the original difference, while others were i(0) variables with a constant term. this was done to determine which variable best described the relationship between the two sets of variables. each aspect's value was carefully global sustainability research global scientific research 58 evaluated. these features were studied and contrasted before being grouped and summarized. by pooling explanatory component leads and lags, this estimate overcomes small sample bias, endogeneity, and autocorrelation (begum et al., 2020). after determining that the variables under inquiry cointegrate, equation (5) was used to estimate the dols long-run coefficient. δlct = τ0 + τ1lct−1 + τ2ltt−1 + τ3lyt−1 + τ4let−1 + ∑ γ1 q i=1 δlct−i + ∑ γ2 q i=1 δltt−i + ∑ γ3 q i=1 δlyt−i + ∑ γ4 q i=1 δlet−i+ εt (5) where δ is the first difference and q is the optimum lag length in the above equation (5). results and discussion skewness, kurtosis, probability, and jarque-bera normality tests are shown in table 2. the kurtosis statistic was used to identify whether the series had light or heavy tails compared to the normal distribution. the empirical evidence shows that each series is platykurtic since every value is smaller than 3, the critical number. skewness scores around zero suggest that all variables have met the normality premise. low jarque-bera probabilities indicate normal parameters. table 2. summary statistics of the variables variables lc lt ly le mean

1% level, shows that a 1% increase in tourism leads to a 0.50% increase in co2 emissions over time. this study found a strong correlation between singapore's carbon dioxide emissions and tourist numbers. tourism increases singapore's air pollution, which worsens the environment. the study found that more visitors visiting singapore increases energy usage and climate change. since the research study's conclusions match those of other singaporean studies, this discovery is not surprising. zhang and liu (2019) found that singapore's carbon dioxide emissions increased with foreign tourists. in addition, research from other countries, such as ng et al. (2015), zaman et al. (2016), dogan et al. (2017), ahmad et al. (2019), ali et al. (2020), selvanathan et al. (2021), and raihan et al. (2022c), supports the current study's conclusion that tourism and co2 emissions in singapore are positively correlated. however, if tourism is not planned and controlled, it may harm the environment, which is vital to the tourism industry. tsai et al. (2014) found that hotels with better service levels emit more co2 per guest. international tourism and travel spending increase carbon dioxide emissions in wealthy and developing nations (zaman et al., 2016). dogan et al. (2017) also revealed that tourism increases co2 emissions through various modes of transportation, touristic infrastructure development, and local government and commercial services. the travel and tourist business is a major contributor to the degrading environment. tourism generates greenhouse gas emissions in transportation, energy, and heat production (ng et al., 2015). tourism harms the biophysical and sociocultural environment. tourism releases smoke, sulfur dioxide, nitrogen oxides, and other hazardous pollutants into the atmosphere, deteriorating the environment. tourist activities may damage the ecosystem, making the site less appealing. waste mismanagement may turn a beautiful spot into the trash. tourism also causes noise pollution from vehicles. the growth of the airline sector, hotel occupancy, and motorized boat use have all contributed to this issue (raihan & tuspekova, 2022b). sustainable tourism is necessary to reduce tourism's negative impacts on society, the environment, the climate, and the economy. table 5. dols outcomes: dependent variable lco2 variables coefficient standard error t-statistic p-value lt 0.498110*** 0.314185 1.585401 0.0013 ly -0.035536* 0.060398 -0.585401 0.0719 le 0.880200*** 0.329043 2.675034 0.0025 c 3.729782 1.843548 2.023155 0.1153 r2 0.923172 adjusted r2 0.902524 standard error of the estimate 0.057280 long run variance 0.007186 mean of the dependent variable 10.59614 f-statistic 1129.36 prob (f-statistic) 0.000000 root mean square error (rmse) 0.021297 mean absolute error (mae) 0.018543 ***, **, and * denote significance at the 1%, 5%, and 10% levels, respectively. singapore is used as a case study to see if economic production and environmental pollution are related. despite ly's negative long-run coefficient, this discovery is statistically significant at 10%. this means that singapore's co2 emissions will reduce by 0.03% for every 1% increase in economic development. this study found that economic growth did not harm the environment. the result shows that an expanding economy negatively impacts co2 emissions over time. the result showed that singapore's ability to sustainably manage its environment increases with economic development. the study result is supported by katirciolu (2014), mehmood (2021), and mansoor (2021)'s conclusions that singapore's gdp and co2 emissions are inversely related. studies from other countries also supported our findings. for example, zaman et al. (2016), ali et al. (2020), ng et al. (2015), ahmad et al. (2019), selvanathan et al. (2021), dogan et al. (2017), raheem and ogebe (2017), liu and bae (2018), vo et al. (2019), raihan et al. (2022e), odugbesan and adebayo (2020), adebayo and kalmaz (2021), nondo and kahsai (2020). singapore's economy will rise which could improve air quality, as predicted by (mehmood 2021). even while economic expansion may improve human existence, it is crucial to determine if and how it may be made sustainable (raihan et al 2022g). development activities satisfy more societal demands as economic growth rises. these actions increase pollution, waste, and environmental damage (raihan and global sustainability research global scientific research 60 tuspekova, 2022b). thus, economic activities appear to protect and improve the environment rather than endanger it. however, not all economic growth is destructive to the environment or incompatible with environmental preservation. as income rises, people will be able to donate more to causes like environmental protection and pollution reduction. tech-driven economic expansion boosts productivity and reduces pollution. this research focuses on singapore's high energy usage and environmental degradation. this study confirmed that fossil fuels constitute singapore's main energy source, which increases co2 emissions over time. the anticipated longrun coefficient of le is positive and statistically significant at the 1% level, indicating that a 1% increase in energy consumption in singapore increases co2 emissions by 0.8%. as energy consumption rises, the environment will deteriorate. according to dols's extrapolations, greater tourism in singapore boosts the economy but worsens the environment due to higher energy usage. this study's finding is consistent with singapore's study by katirciolu (2014). the positive association between energy use and co2 emissions supports previous studies that found many nations largely rely on coal, natural gas, and oil, which increases co2 emissions and environmental deterioration. for example, dogan et al. (2017), raihan et al. (2022a), raheem and ogebe (2017), liu and bae (2018), vo et al. (2019), raihan et al. (2022e), odugbesan and adebayo (2020), adebayo and kalmaz (2021), nondo and kahsai (2020), ali et al. (2020), ng et al. (2015), ahmad et al. (2019), selvanathan et al. (2021), and raihan et al. (2022f). the present study’s result shows that singapore's environmental quality is worsening as energy demand rises. despite this, 86% of singapore's primary energy comes from petroleum and other liquids, and 13% from natural gas. thus, building a renewable energy infrastructure that can replace fossil fuels is the most important policy. renewable energy sources are needed to ensure sustainable development and mitigate climate change's negative effects (raihan et al 2022h). renewable energy boosts the economy and lowers carbon emissions. it is eco-friendly and other benefits include increased energy availability and energy security (voumik et al., 2022b). as global environmental consciousness rises, singapore must switch to renewable energy sources to enable the use of environmentally friendly energy sources and the creation of an eco-friendly ecosystem. renewable energy accounts for less than 1% of singapore's primary energy demand. singapore needs a comprehensive renewable energy policy to transition to a low-carbon economy. however, the singaporean government is investigating several ways to cut carbon emissions. the singapore carbon pricing act started operationally in 2019. this statute required carbon pricing. the singapore energy market authority (ema) recently launched "4 switches." this effort promotes clean power production. the energy management agency (ema) will research energy storage technologies for variable energy flows and potential technical solutions including carbon capture and storage. regional electricity systems are another ema focus. singapore approved its "green plan" to mitigate climate change. the plan aims to add more than 321 acres of parkland, prohibit new diesel car and taxi registrations starting in 2025, establish 60,000 vehicle charging outlets nationwide by 2030, with twothirds in public parking spaces and one-third on private property, and increase solar irradiation. singapore launched a nationwide 111-acre floating solar panel farm in july 2021. the world's most powerful floating solar farm generates 60 megawatts of power. singapore's five water treatment plants provide enough hydropower. the national water agency of singapore expects the sembcorp industries-owned solar farm in singapore to reduce carbon emissions by 32,000 metric tons. it's crucial to note that the projected coefficients' signs are constant conceptually and practically. the current investigation uses many diagnostic methods to determine if the predicted model accurately represents reality. this study examines whether the calculated model matches reality. the revised regression model fits the data well, with an r2 value of 0.92 and an adjusted r2 of 0.90. these figures show that the independent factors might account for 90% of the dependent variable's change. the f-statistic supports the computed dols regression from both the dependent and independent variables. given the f statistic's 0.0000 pvalue, the model's variables' linear relationship is statistically significant. third, the root mean square error and mean absolute error helped evaluate the model's predictions. the rmse and mae figures were near to 0 and did not indicate a negative value supporting the model’s fitness. to verify cointegration analysis, this study tested for normality, heteroscedasticity, and serial correlation. table 6 summarizes the diagnostic test results. residuals follow a normal distribution, according to four studies. the model also suggests no autocorrelation or heteroscedasticity. to determine model stability, the cumulative sum of recursive residuals (cusum) and the cumulative sum of squares of residuals (cusumq) tests were applied. figure 3 shows cusum and cusumq statistics

examined the relationship between economic growth, tourism, energy consumption, and co2 emissions in singapore using time series data from 1990 to 2020. the adf, df-gls, and p-p unit root tests were utilized in order to determine the integration order of the series. the findings from the dols estimation revealed that tourism and energy use raise co2 emissions, which degrade singapore's environment, but economic expansion decreases co2 emissions in the long run. this article proposes environmental policy concepts to ensure the long-term viability of the environment by implementing strict regulatory policy tools to stop environmental deterioration. the outcomes offer recommendations to governments seeking to achieve environmental sustainability while minimizing climate change's effects and adapting to them. the analysis found that singapore's government might help markets by creating a rigorous regulatory framework that produces long-term value for emission reduction and continuously supports innovative solutions that reduce carbon dependence. singapore may continue to establish rules like a high carbon tax, carbon capture and storage, and emission trading schemes to minimize carbon dioxide emissions from fossil fuel combustion in industrial processes and power generation. decoupling regionally involves changes in centralized nations' policies, conduct, and scientific and technological advancement. this will allow modernization based on technology that can meet growing demand while preserving natural capital. the government's main responsibility is funding research and development to reduce production's resource use and energy efficiency. for singapore's stronger economic growth to reduce environmental challenges, the economy must convert to renewable energy. legislators may help corporations create innovative technology and sustainable energy. institutional alignment also promotes sustainable economic growth and the use of renewable and alternative energy in all economic activities. in addition, environmental regulations must be meticulously followed. the study suggests using more renewable or clean energy sources to optimize singapore's energy consumption structure performance. the latest study supported this notion. conventional energy, which still dominates singapore's energy use, is the main source of its high carbon dioxide emissions. singapore may transition to renewable energy to decrease its environmental impact. due to the limited area for renewable energy generation, practically all of singapore's energy is imported. singapore can meet all its renewable energy needs since solar energy is so abundant. singapore has very strong sun radiation. singapore may invest in innovation, research, and test beds to improve solar power system efficiency and explore creative ways to integrate them into urban areas. singapore may examine regional power networks and create lowcarbon solutions like low-carbon hydrogen utilization and carbon capture and storage to boost energy security and explore new energy supply possibilities. singapore is constantly researching new energy sources to promote energy diversity and security. this would be part of nationwide efforts to provide reliable electricity availability. singapore wants to continue research into nuclear energy and create the necessary capacities to understand nuclear science and technology, even though some technologies, like nuclear power, may become obsolete. singapore can enhance its energy education programs. tax incentives, economic subsidies, and government acquisitions can encourage greener energy consumption. there is a possibility that the government will enlist the assistance of the media in order to further its push for "low-carbon behaviors and consumption patterns" and its "green lifestyle notion." -16 -12 -8 -4 0 4 8 12 16 94 96 98 00 02 04 06 08 10 12 14 16 18 20 cusum 5% significance -0.4 -0.2 0.0 0.2

put in place a system that will hold individuals, tourists, and other interested parties accountable for the damage they cause to the natural environment of the country's most popular tourist destinations. this will allow singapore to continue to attract tourists to its most beautiful and unique areas. not only would tourists have an overall more positive experience if all parties involved in the tourism industry were encouraged to embrace sustainability and environmental responsibility in their business practices, but they would also benefit from an increase in their level of education as a result of this. this is due to the fact that visitors would enjoy a more satisfying experience all around. in addition to educational pamphlets and booklets, it is likely that as many public service announcements incorporating easily digestible infographics should be delivered to the general population. people would be encouraged to appreciate the benefits of energy savings and environmental sustainability, as well as to engage in green behaviors while on vacation if these announcements were made, coupled with information on the efforts being made by the authorities and ongoing green development. in addition, the dissemination of this knowledge would motivate individuals to engage in environmentally responsible actions while they are at work. it is of the utmost importance that advancements in transportation technology, such as the employment of high-speed trains and airplanes that consume less fuel, be supported. because of the rise in tourists, there is now a chance to cut carbon dioxide emissions by updating public transportation, investing in energy efficiency, and enhancing waste management. in order to safeguard the environment, the government might also decide to implement and strictly enforce environmental levies in regions that have a high visitor density and are important tourist destinations. additionally, the government should make it less difficult for businesses in the tourism industry to adopt environmentally friendly and low-carbon technology in addition to alternative sources of energy for transportation, logistics, hotels, and other activities. this would result in a decrease in the total amount of carbon dioxide emissions and would also prevent excessive consumption of the earth's natural resources. there is a chance that singapore would tighten the environmental regulations that it already has in place and shine a light on other nations whose tourism industries are contributing to the deterioration of the environment. the concept of "sustainable tourism" can be used to apply to a wide range of distinct sorts of tourism. some examples of these types of tourism include cultural tourism, ecotourism, tourism that is centered on enjoyment and adventure, and educational tourism. it is vital that the governments in the southeast asian region collaborate and coordinate their efforts in order to put proactive measures in place to ensure that tourism is ecologically responsible. however, despite providing a lot of factual data on singapore, the analysis contains several shortcomings that need to be addressed in future research. our study's major flaw was the unavailability of tourism data beyond the study period. this limited the prediction power of the econometric methodologies. using econometric models or microdisaggregated data, other nations can conduct more research. the study suggests studying the dynamic effects of socioeconomic and environmental variables on environmental pollution in developing nations with rapid economic growth to balance ecologically sustainable development with emission reduction. this will help to balance environmentally sustainable development and emission reduction. future research could also consider other development aspects not examined in this study. for example, urbanization, industrialization, trade openness, financial sector development, direct foreign investments, institutional quality, globalization, technical innovation, and others. in order to compare country findings to panel forecasts, a future study may apply more complicated econometric methods. these comparisons with this study's findings may illuminate the relevant literature. acknowledgment: the authors declare no conflict of interest conflict of interest: the authors declare no

orcid id: https://orcid.org/0000-0002-4383-0560 received: 02 september, 2023, accepted: 03 november, 2023, published: 15 november, 2023 abstract in spite of bangladesh's vulnerability to climate change because of its geographical location, geomorphology, and greater dependence on nature, all the communities of the country are not vulnerable to climate change in the same ways. the santals of bangladesh are one of the most climate change-vulnerable communities because they are marginalized because they have fewer physical, natural, economic, human, and social capitals. truly, there is much research on the climate change vulnerability of bangladesh; however, existing research does not discuss this matter. this research was conducted with the objectives of knowing the interaction between bangladeshi santals’ different types of capital, the effects of climate change, and the vulnerability of indigenous peoples to climate change. following the qualitative methodology, this research found that santals of research field are already marginalized because of having no ownership of land, homesteads and livestock, least access to fresh water, naturally-grown vegetables, trees, and crop seeds), no alternative income sources, less annual income and savings, less educational qualifications, less or no knowledge about climate change, no training on climate change and climate change adaptation, no skills for alternative income, and no access to prior warning about natural calamities, less connectivity to organizations, least access to government services, and having few helpful kin relatives, and interaction among these capitals; climate change effects are making them more vulnerable. key words: climate change vulnerabilities; santals of bangladesh; capitals; marginalization introduction climate change is among the most pressing concerns on the globe today. people, ecosystems, and livelihoods have already been impacted by climate change all around the world (masson-delmotte et al., 2019). due to many influences, the world's climate has always fluctuated between warmer and cooler times. according to the ipcc, global temperatures will climb between 1.8 and 4 degrees celsius by the end of the twenty-first century (goosen et al., 2018; ministry of environment and forests, 2009). on the other hand, capitals are another important thing on which human beings depend for their survival. enrichment with natural capitals, physical capitals, economic capitals, human capitals, and social capitals ensures quality life and wellbeing, and low capitals, on the other hand, are known as poverty (flora & thiboumery, 2005). all kinds of capitals are connected with one another (drexler, 2022), and a decrease in one type of capital affects other types. basically, climate change vulnerability is strongly connected with different types of capitals since the interaction of climate change effects and different capitals significantly determines how vulnerable one community will be to climate change. significantly, climate change global sustainability research global scientific research 47 doesn't affect all countries in the same way. developing countries are more vulnerable to climatic change as they have reduced capital and social, financial, and technological means to adapt. developing countries are most vulnerable to potential climate change impacts (unicef, 2016). geographically and geomorphologically, bangladesh is one of the world's most climate-vulnerable countries, and climate change is worsening it (ministry of environment and forests, 2009; displacement solutions, 2012). the agriculture industry is already feeling the effects of climate change and will face increasing issues as climate change increases through altered rainfall patterns, drought, salinity incursion, and soil degradation. climate change has spatial and seasonal effects on the country's water cycle. too much water in the monsoon season and too little in the dry periods, as well as altering rainfall patterns, hinder agricultural production, navigability, ecology, and biodiversity (ministry of environment and forests, 2012). however, all parts of this country aren't equally vulnerable to climate change since bangladesh is separated into various climatic areas and each region is subject to climate variability (goosen et al., 2018; ministry of environment and forests, 2009). at the same time, all communities in climate-vulnerable regions aren't equally vulnerable to climate change. climate change can make vulnerable people more vulnerable (unicef, 2016). indigenous populations are marginalized and vulnerable because they live in climate-sensitive areas, face discrimination and exploitation, and lack rights. they are more vulnerable to climate change than others (international labour organization, 2017; unicef, 2016). there is a lot of research on the effects of climate change on natural and economic capitals in bangladesh; however, research on the effects of climate change on the indigenous peoples of bangladesh has not been conducted yet. as a result, a complete scenario of bangladesh's vulnerability to climate change is hardly found. however, in order to set a long-lasting and effective policy, there is also required research on the climate change vulnerabilities of bangladeshi indigenous people. considering its importance, this research has been conducted. the santals are also indigenous people of bangladesh who mainly live in the northwestern part of the country (islam, 2003), which is very vulnerable to climate change (rahman & lateh, 2016; goosen et al., 2018). as indigenous peoples are already marginalized and vulnerable to climate change (international labour organization, 2017; unicef, 2016), the santals of bangladesh can be considered one of bangladesh's most vulnerable communities. in this research, the climate vulnerability of the santal people of a village in rajshahi district has been discussed. research objectives the study has been conducted with the following objectives: • to understand how the interaction of different types of capital in the santal community and the effects of climate change are occurring, and • to know the nature of the vulnerability of santals to climate change. literature review according to the ministry of environment and forests (2009), climate change hinders bangladesh's potential to achieve high economic growth due to severe floods, tropical cyclones, storm surges, and droughts. bangladesh's natural catastrophes kill people, ruin infrastructural and economic assets, and harm the underprivileged. frequent and intense tropical storms are causing coastal damage; heavier and more irregular rainfall during the monsoon is leading to heavier river flows, river bank erosion, and higher sedimentation; the himalayan glaciers' melting causes heavier river flows and salt intrusion; lower and more irregular rainfall is increasing drought; and sea level global sustainability research global scientific research 48 rise causes saltwater to enter coastal rivers and groundwater; warmer and drier conditions are also contributing to the problem. each of these shifts affects agriculture and agriculture-dependent communities, reducing crop yields and production. coastal erosion and saline water intrusion cause people to migrate. however, how the specific communities of bangladesh, such as indigenous communities, are differently affected by these climate change vulnerabilities has not been revealed by the ministry of environment and forests (2009). in the same way, according to goosen et al. (2018), as a result of climate change, the intensity of droughts, rainfall, cyclones, storms, and coastal flooding is increasing. droughts cause soil dryness and hydrogeological inequity, resulting in water scarcity, overexploitation, very reduced stream flows, scarcity of food, livestock fodder insufficiency, and drinking water scarcity; floods have impacts on life, livelihoods, drinkable water, sanitation, health, electricity, and infrastructure; cyclones, storms, and coastal flooding also have impacts on the economy and society. during such events, cattle and poultry frequently die or are lost, further impacting local people who rely on livestock and agricultural supplies. however, how the specific communities of bangladesh, such as indigenous communities, are differently affected by these climate change vulnerabilities has not also been revealed by goosen et al. (2018). similarly, unicef (2016) also found that, as a result of climate change, the intensity of floods, droughts, cyclones, river erosion, and tidal surges is increasing in bangladesh, which has impacts on health, agriculture, education, cattle, water, and infrastructure. unicef (2016) also did not focus on how specific communities in bangladesh, such as indigenous communities, are differently affected by these climate change vulnerabilities. the world bank group (2021) also found that because of climate change, the intensity of floods, droughts, cyclones, river erosion, and tidal surges is increasing in bangladesh, which has caused death, unemployment, damaged assets, agriculture, and infrastructure, and reduced income. the world bank group (2021) also did not focus on how specific communities in bangladesh, such as indigenous communities, are differently affected by these climate change vulnerabilities. in the same way, ahmed (2006) mentioned that climate change has increased the intensity of climatic disasters such as floods, droughts, river bank erosion, and sedimentation in bangladesh, which has already had an impact on agriculture, aquaculture, shrimp culture, livestock, forests, human health, infrastructure, and livelihood. however, ahmed (2006) also did not value how specific communities in bangladesh, such as indigenous communities, are differently affected by these climate change vulnerabilities. research methodology this research was conducted in ramdevpur abasan in tanore upazila of rajshahi district, which consists of 40 households of mainly 2 categories of occupation, i.e., sharecropper1s and wage laborers. this research is basically qualitative; however, the researcher also gave importance to the quantitative information to understand the community's status. both primary and secondary information were used in this research. to collect quantitative primary information, the researcher visited all the households. a questionnaire was used to collect the quantitative primary information. on the other hand, to collect qualitative primary information, the random sampling method was used while selecting samples for this research. the sample size for collecting qualitative information was not predetermined; however, information was collected from the members of this village until data saturation. the researcher had discussions with 15 people from this village using different qualitative research tools. among these discussions, 1 was a key informant interview, 6 were in-depth interviews, and 1 was a focus group discussion (fgd) consisting of 8 people. during the researchers’ first appearance at the village, the key informants were selected from the villagers among the oldest and most knowledgeable members by discussing with people. then the researcher conducted the focus group discussion (fgd) to learn about different professional groups’ 1 sharecropping is known as bagi in the research field. global sustainability research global scientific research 49 perceptions of climate change and community experience. the researcher also met with six people from different professional groups in order to conduct in-depth interviews to learn about their personal experiences with climate change. on the other hand, for secondary sources or literature, the researcher has collected literature, both global and local, that goes with this study's objectives and is relevant to this study and sorted it out under a larger categorization. the document review method was used as a secondary qualitative data collection tool. after the completion of data collection, information collected by qualitative research tools such as key informant interviews, in-depth interviews, and focus group discussions (fgds) was coded based on their similarities and analyzed following the thematic analysis method, i.e., categorized under the broader themes. at the same time, quantitative information was analyzed using microsoft excel software, and relationships among the same items of coded information were drawn. unstructured interviews and observation methods were used in order to collect primary data. the household has been considered a unit of analysis in the study. the inductive analytical method has been used in this research. findings and discussion findings interaction of physical capitals and climate change vulnerabilities livestock ownership is the only physical capital for the santals of ramdevpur abasan. among the santal households of ramdevpur abasan2, only 66.7% of households have cattle, and the rest, 33.3%, have none. among these cattle, goats are found in most households since they can be bought easily at a comparatively low price and can be sold when needed. many of the santal people prefer goats to cows since the households’ small children can also cut grass for the goats. on the other hand, these goats can be gotten by bagi3, and their offspring can be regarded as household assets within a few months. but many of them brought goats from their previous residences. there are some households that raise cows. generally, those who cultivate more rice in the bagi fields and do not go outside for work rear cows the most. it is true of both cows and goats that people bring them from their previous residence. their livestock rearing is affected by climate change. it is found that when it rains repeatedly for a few days, they cannot feed them grass. on the other hand, when grass dies because it is not raining, their livestock suffer from hunger. as a result, the santal residents of the abasan are quitting rearing livestock, and income from selling them is not coming from it, which forces them to take loans from the mohajon4s at high interest rates when they need money. except for ownership over livestock, the santals of ramdevpur abasan do not have any type of physical capital; they neither have nor have had homestead lands of their own. the place where the abasan is located also does not belong to them since it is khas5 land, and they will not also live here for a long time. they also did not have homestead land in the villages from where they once came. some of them lived on other people’s land, building small houses. as a result, they do not have alternative residences. at the same time, as they do not have ownership in the lands in the abasan, they are not permitted to build residences with concrete, and they build additional houses with straw, which results in damages every year because of wester storms. as a result, they repair their 2 abasan is a government-built shelter for the poor, especially in rural areas. 3 in the bagi system of rearing cattle, the bagi takers receive cattle and rear them. the first cab is given to the rearers, and the second one is given to the owners of cattle. 4 village elite who lend money with high interests. 5 government-owned land. global sustainability research global scientific research 50 houses every year, which increases their loans, food shortages, and obstacles to savings. the santal households that reside in the abasan also have no land ownership from long ago. they do not even have cultivable lands in their native villages, from where they once came here. lack of cultivable lands has forced many of them to work as wage laborers and few of them to cultivate rice in the bagi system, where produced rice is divided into three portions and the producers get two thirds of the rice. generally, they are given comparatively high lands in the bagi system, which is not production friendly; they can produce not more than 15 mon6 of rice in 1 bigha7 of land and get 10 mon of rice in the bagi system. however, all the household expenses are difficult to manage with the rice they get. especially when crops are damaged due to droughts and temporary floods, their investment in cultivation goes to waste. as a result, they are forced to take loans. interaction of natural capitals and climate change vulnerabilities natural resources such as fresh water, naturally-grown vegetables, trees, and crop seeds are found as natural capitals among the santals of ramdevpur abasan. in ramdevpur abasan, water comes from tube wells (ground water), rain, and ponds. among them, water from a tube well is treated as drinking water since their ancestors used ground water for drinking. water from rain and deep tube wells is used in cultivation. there are four ponds in this village, and water from the ponds is used for fish cultivation, taking baths, washing cloths, and cocking instruments. it is found that a total of 72.2% of the santal people of ramdevpur can access drinkable water, which they fetch from a mini-deep tube well. however, the water crisis is a major problem in ramdevpur abasan. it is found that 5.6% of them, 11.1% of them, 27.8% of them, 50% of them, and 5.6% of them cannot get drinkable water consecutively for 6 months, 7 months, 8 months, 9 months, and 12 months in a row. especially during the drought, santals in this region face a variety of challenges in obtaining water. santals are not allowed to collect water from the tube wells belonging to bengali people because of their love for eating pork and the meat of hunted animals. when the tube wells of the abasan cannot fetch water in the early drought period of november to january, they fetch water from neighboring villages, which are two kilometers away from the abasan. besides drinking water from deep tube wells, pond water, which they also use for bathing, cleaning clothes, and cleaning plates and dishes, is also unavailable to them because of their lack of ownership and the use of animal dust, heavy fertilizer, and chemicals by bengali people with the intention of commercial fish cultivation. because they do not have ownership over ponds, they are not allowed to forbid bengali people from using dirt in ponds. their poverty also does not allow them to dig deep tube wells to overcome water scarcity. like fresh water, naturally-grown vegetables are found to be natural capitals among the santals of ramdevpur avasan. 77.8% of households in this abasan can have access to naturally growing vegetables for 15 days. basically, the votua shak, knata shak, and other wild vegetables can be taken until they do not get old. only 22.2% of households can avail themselves of access to natural resources for 30 days. it is kochu shak, which grows on the pond side in the rainy season. however, people are unable to consume it because it dries up during the drought season. households with members who work outside the community are more likely to have limited access to natural resources. apart from naturally-grown vegetables, trees are important natural capitals at ramdevpur abasan. there are bamboos and palm trees at the abasan. santals living here make baskets with bamboo and mats with the leaves of palm trees. their houses are also made and repaired with bamboo and palm leaves. 6 1 mon contains 40 kg of product. 7 1 bigha contains 33 decimals of land. global sustainability research global scientific research 51 crop seeds are also found to be ramdevpur abasan santals’ natural capitals. it is found that 16.7% of households keep the seeds as they cultivate vegetables on homesteads and rice in the jhina system. if they do not have seeds or comparatively good seeds, they collect them from their close relatives. these people sometimes buy seeds from the market since they are easily found there, which sometimes leads them to not conserve seeds at home. however, 83.3 percent of households do not have crop and vegetable seeds because they believe they will be useless due to insufficient land in the abasan, uncertain living conditions in the abasan, and no land of their own. interaction of economic capital and climate change vulnerabilities the economic capitals of the santals of ramdevpur abasan include the number of income sources, earning members of households, annual income, and family regular savings. it is found that more than half of the households (56.6%) do not have multiple income sources, and the household members of these households work as agricultural daily wage laborers. basically, there is no opportunity to do other activities, which makes people depend more on wage labor and rice cultivation in the jhina8 system. on the other hand, the total households that have multiple income sources account for 44.4% of the total households. basically, the household members of these households work as daily wage laborers, cutting rice in the jhina tradition and digging soil. ramdevpur santal's expertise also extends to making baskets and mats, which they learned from their ancestors and neighbors. it can be seen that whatever income sources the santals of ramdevpur have are basically agricultural and naturebased. as a result, the effects of climate change on the income of the santals of ramdevpur abasan are well imagined; people cannot grow rice and other rabi crops9 in the winter season due to water scarcity. on the other hand, in the monsoon season, it rains here a lot, just as it does in other parts of bangladesh. as a result of excessive rain, land at lower levels goes under water. in the rainy season, when aus10 and aman11 rice are cultivated, this place remains uncultivated because of the flood-like situation. people can also not tend cattle or cut grass for their cattle on these lands. on the other hand, people who are wage laborers lose their jobs in their community when there is no water due to droughts or floods. those who have expertise in making baskets and mats are also about to make no use of their skills since there is a lack of trees because of draught. being engaged in nature-based income sources leads people to a shortage of food, jobs, cattle, and grass and forces them to migrate to mohanpur, durgapur, or rajshahi city. sometimes, the santal males of this abasan migrate to faridpur for 15–20 days and work as agricultural day laborers. those who migrate to dhaka generally work as garment workers with low wages. besides the number of income sources, earning members of households also play an important role as economic capitals. it is found that 44.4% of ramdevpur households have one earning member, and 38.9% of households have two. only 5.6% of households have three, and 11.1% of households have four earning members. most households with one earning member have a male earning member. however, female-headed households, as a result of the husband’s illness and death and having no one left behind, lead women to earn. sometimes, as partners of males, female members of these households work to reduce poverty and ensure food security. children who are not continuing their studies are engaged in income-generating activities. based on the number of income sources and earning members, the annual income of the 18 santal households of ramdevpur abasan also differs from each other. it is found that 5.6% households, 11.1% households, 11.1% 8 a traditional harvesting system where the wage labourers cut and thresh paddy in exchange for 7-8 kg of rice per 40 kg paddy and distribute among themselves. 9 crops that are sawn in the winter season. 10 a type of paddy planted in the month of may and harvested in july. 11 a type of paddy planted in the months of july-august and harvested in november-december. global sustainability research global scientific research 52 households, 11.1% households, 16.7% households, 22.2% households, and 5.6% households consecutively have a yearly income of bdt 15000, bdt 16000, bdt 18000, bdt 20000, bdt 22000, bdt 24000, bdt 25000, bdt 30000, and bdt 40000. the difference in households’ yearly income is caused by the difference among the incomes of their earning members and the employment opportunity, since the households with more earning members have more income opportunities, and people are employed as agro-wage laborers for 15 days in january for planting boro rice, 15 days in april-may for harvesting boro rice12, 15 days in july-august for planting aman rice, and 15 days for harvesting aman rice. at the same time, there is discrimination in the wages of males and females, which causes the comparatively decreased yearly income of households with female earning members compared to households with male earning members. however, the household members who are going to godagari and tanore, where cultivation is made possible with the help of deep tube wells, are likely to have more income. the households with less income are to take loans from different sources. it is found that 7 households out of a total of 18 households have loans, whereas 11 households do not have loans. among these 7 households, 16.7%, 33.3%, 16.7%, and 33.3% of households have loans consisting of consecutively bdt 2000, bdt 5000, bdt 10000, and bdt 14000, which are taken from the mahajons and abasan co-operative. basically, the formalities of abasan co-operative in taking loans lead people to the mahajons since it is easier to take loans from them than from the co-operatives. santals of this abasan generally take loans to buy food in times of food scarcity and impending needs for visiting doctors and building tube wells. salman says, "when you need bdt 500–1000, you will think selling your cattle is illogical since you will not get it back because of your family's needs. when the time of harvesting comes, the heads of these households pay the loans by working without taking wages. but those who cultivate rice in jhina lands sell their rice and give the money back. people who cultivate fewer jhina lands are likely to be more vulnerable to food crises since they sell most of their rice to pay the loan with high interest. in the last 5 years, the occurrence of taking loans increased because of damaged crops due to droughts in november–march, hailstorms in april–may, and temporary floods in may and november. savings, which act as economic capital, are also found to be lower among the santal households of ramdevpur abasan. 88.9% of ramdevpur santal households do not have savings. there is one household that has a regular monthly savings of bdt 100 and another household that saves bdt 200 per month. their more frequent expenses than income because of repayment of debt, buying food, production costs, and damages to crops and assets do not let them save money in their account regularly. kangana soren asserts, "we are living hand to mouth since we do not have savings and are lending money when we do not have it." interaction of human capital and climate change vulnerabilities the human capital of the santals of ramdevpur abasan includes educational qualifications, knowledge about climate change, training on climate change and climate change adaptation, skills for alternative income, and prior warning about natural calamities. it has been observed that there is a government primary school just beside the abasan. however, only 11.1% of the household heads have primary-level education, 5.6% have secondary-level education, and 83.3% of the household heads are illiterate, i.e., they have never gone to school. basically, poverty, being far away from schools, the unconsciousness of their parents, their little knowledge regarding education, and the unfamiliar environment of schools resulted in their limited access to education. the nearly constant presence of primary schools inspires the abasan people to send their children to school. as many of the santal household heads of 12 a type of paddy planted in january and harvested in april-may. global sustainability research global scientific research 53 ramdevpur abasan lack formal education, they do not have the opportunity to engage in service jobs, which are not affected by climate change. at the same time, 44.4% of household members can imagine that the climate is changing, whereas 56.6% of household members do not have knowledge regarding climate change. those who have knowledge of climate change think that the barind13 region is drought-prone, but the recent hotter climatic situation has never been felt before, and their traditional adaptation strategy is not working well. heavy rain in recent inaccurate times has been decreasing their crops, which has made many of them realize climatic changes. the people of ramdevpur also do not have training on climate change and climate change adaptation since there was no training in this abasan in which they could have participated. moreover, they do not even know their relatives who participated in such training. as a result, they have no idea how they can cope with climate change and mitigate climate vulnerabilities. it is also found that 83.3% of societal households’ members do not have alternative income skills and are dependent on agriculture for their livelihood. the rest (16.7% of households’ members) got training on cow health and sericulture, but these skills are not meeting their practical needs since they lack the cows they need. on the other hand, the skills of making baskets with bamboo branches and mats with palm leaves have been acquired by seeing their relatives, which are of no use since there is a lack of these trees in this abasan because of droughts. at the same time, no household members get any prior warning regarding disasters, and none of them have been to any organization or agency office to get information in this regard since they did not even know that this information could be known from any offices. all they know about climate change is based on their perceptions and experiences. their lack of confidence stemmed from a lack of educational qualifications, poverty, and the experience of being ignored solely because they were santals, so they did not dare go to any offices for information. as a result, they cannot prepare for any natural calamities, which results in damage to their assets. interaction of social capital and climate change vulnerabilities the social capitals of the santals of ramdevpur abasan include connectivity to organizations, access to government services, and having helpful kin relatives. however, not all households have access to these capitals. there is a cooperative organization in this abasan, and all the households, regardless of their ethnic identity, are members of the abasan cooperative. besides this, only one santal man is found to be a member of the managing committee of a local school. 33.3% of households’ members have membership in any ethnicity-led organization (clubs, social, and cultural). there is no union parishad member from this abasan, and the santals of this abasan also do not have any connection with union parishad members. aside from that, only a small number of santal people are members of national-level ethnic organizations and ngo-led small groups. as a result, they cannot request any union parishad member to set a tube well in this abasan. at the same time, since the santals of ramdevpur abasan do not have connectivity with the union parishad office, they do not get information about safety nets and government assistance. as a result, the local union parishad office provides almost no assistance to the santal people of ramdevpur abasan; there is only one (5.6%) household whose members got allotted a residence in the abasan in 2017, and the rest, 94.4% of households, did not get any kind of aid. among the 18 households, 27.8% have kin or relatives who can help them in disasters. many of these households’ members recently got married and have connections with their parents. they have shared money, rice, and vegetables with them. this sharing also happened with the fictive relatives. on the other hand, 72.2% of 13 ramdevpur abasan is located in the barind tract region, which contains the northern-southern part of bangladesh with fewer trees, hard and stair-like geographical landscape, and less rainfall. global sustainability research global scientific research 54 households do not have such relatives who can help them in crisis situations. many people who reside in this area have no social connection with the place where they once lived and have left their neighbors and kin. the rest of the people who have little ties to their previous residence and kin relatives also lack the assistance of relatives because their relatives are poor as well. discussion although bangladesh is a multicultural country, bangladesh's santals and other indigenous communities are among the country's most vulnerable and marginalized groups for a variety of reasons, including the ongoing loss of land and natural resources, language and culture, and a lack of access to adequate public services (international labour organization, 2017). indigenous peoples are marginalized due to high levels of illiteracy, unemployment, exploitation by political leaders and middlemen, a lack of infrastructure, and the media's unsupportive role (sahoo, 2016). their limited access to education and knowledge stops them from getting accurate information about government and development agency opportunities (sharif, 2014). santals' cultural food habits restrict eating at local restaurants and food shops, and the bengali community's carelessness and disdain of ethnic food systems create a situation where ethnic children do not sit in the same classroom as bengali children (sarker & davey, 2009). indigenous peoples have already been socially, economically, politically, and geographically isolated as a result of discrimination and hatred. the santals of ramdevpur abasan are found to have similarities with the other santals of bangladesh in terms of different types of capitals, e.g., physical capitals, economic capitals, natural capitals, human capitals, and social capitals. similarly, physical capitals such as livestock ownership, homestead ownership, and cultivable land ownership among the santals of ramdevpur abasan are found to be poor. there are no cultivable or living lands owned by any households in that abasan, and only a few households have cattle. like their physical and economic capitals, their natural capitals, such as fresh water, naturally grown vegetables, trees, and crop seeds, are limited in their access. pond water, which is a source of fresh water in this abasan, is also dirty and unusable for domestic purposes because of animal and chemical dust. their economic capital is also found to be short since many of the households have loans with high interest rates, less yearly average income, less family regular savings, fewer multiple income sources, less nature-based income, and fewer earning members of households. human capital among the santals of ramdevpur abasan is also poor. many household heads are found to have no educational experience, have no ideas regarding climate change, have no training on climate change and climate change adaptation, have no capacity for alternative income, and have no access to information. their social capital is also found to be poor since they do not have connectivity to organizations, have a smaller number of helpful relatives, and have no access to government services. again, all types of capitals are also found to be linked to each other. ramdevpur abasan’s santal households’ lack of land is making them more dependent on daily wage labor and producing crops in an exploitative bagi system. less income from agricultural wage labor jobs does not help them save; rather, it sometimes leads to higher amounts of loans, which force them to give large sums of money and crops to others. in addition, people suffer from a food crisis again. their poverty, in collaboration with being far away from schools, the unconsciousness of their parents, their little knowledge regarding education, and the unfamiliar environment of schools, creates obstacles to getting an education, and it finally keeps them from non-agricultural jobs. their lack of participation in jobs is making them less diverse in their earning sectors. again, jobs in different development, government, and corporate organizations are thought to be prestigious because they require education and increase the possibility of earning more money, which could be helpful in creating physical, social, economic, and human capital. at the same time, their experience of being hated and neglected by people of the bengali community led global sustainability research global scientific research 55 them to have no membership in any organizations of other communities, which led them to get no government and ngo opportunities or information regarding these opportunities, which could assist them in overcoming their situation. on the other hand, their lack of ownership of physical and social capital is not allowing them to access natural capital, e.g., pond water. in the existing situation of marginalization of the santals of ramdevpur abasan, the climate change effects are about to interact with the different types of capitals of ramdevpur abasan’s santals and are forcing them to be more marginalized as a result. the natural hazards in ramdevpur, namely drought, flood, and storm, which are occurring more frequently in recent years as a result of climate change, are bringing a number of changes to this village. santal farmers cannot grow boro rice and other robi crops in the winter season due to drought. on the other hand, in the monsoon season, it rains here a lot, and as a result of excessive rain, land at lower levels goes under water. in the rainy season, when aus and aman rice are cultivated, this place remains uncultivated due to a flood-like situation. on the other hand, people cannot also tend cattle or cut grass for their cattle on these lands. this condition leads to a shortage of food, jobs, cattle, and grass. on the other hand, santals who do not cultivate are bound to work on other people’s lands. when there is no water because of droughts, they lose their jobs in their locality. both heavy rain in the monsoon and no rain in the drought season lead to joblessness and poverty. apart from cultivation, climate change effects also interact with natural capital. during the drought, santals in this region face a variety of challenges in obtaining water. since santals are not allowed to collect water from the tube wells belonging to bengali people only because of their love for eating pork and meat from hunted animals, they are to bring water from other santal villages. at the same time, alternative sources of water, e.g., ponds, are coming to no use as the santals of ramdevpur abasan do not have control over them. their poverty also does not allow them to dig deep tube wells to overcome water scarcity. having no cultivable lands allows them to work on other people’s lands. indigenous peoples around the world, including the santals of bangladesh, are vulnerable to changes in climate. in terms of social, economic, and environmental vulnerability, indigenous peoples are among the poorest and most threatened portions of the world's population. their economic, social, and cultural activities depend on natural materials that are subject to increased risk due to climate change and extremes. they continue to live in geographical areas and ecosystems that are most vulnerable to climate warming. indigenous peoples' sensitivity to changes in climate can necessitate migration. in most situations, this leaves individuals more exposed to prejudice, exploitation, and environmental concerns in their destination countries. migration typically causes the loss of economic, social, and cultural activity. climate change exacerbates gender inequality, a crucial determinant of indigenous women's impoverishment. indigenous women play an important role in traditional and nontraditional sources of income, unpaid work duties, and food security, but they face internal and external discrimination. indigenous peoples' rights and institutions are often ignored (international labour organization, 2017; unicef, 2016; international labour organization, 2016). if the climate change effects continue to be higher, the indigenous peoples will have no other options but migration to cope (international labour organization, 2017), as it has already started among the santals of ramdevpur abasan on a temporary basis. conclusion it can be analyzed from the above discussion that the santals of ramdevpur abasan lack different types of capital: physical capital such as land ownership, homestead ownership and livestock ownership, economic capital, natural capital such as access to fresh water, naturally-grown vegetables, trees, and crop seeds, human capital such as alternative income sources, annual income and savings, educational qualifications, knowledge about climate change, training on climate change and climate change adaptation, skills for alternative income, and access to global sustainability research global scientific research 56 prior warning about natural calamities, and social capital connectivity to organizations, access to government services, and having few helpful kin relatives, which force them to be marginalized by interacting among themselves. in the context of their already marginalization, climate change effects such as draughts, floods, and storms make them more marginalized and dependent on loans from the local mohajons, and finally force them to migrate, which puts them under the threat of cultural loss. declaration acknowledgment: the researcher

(shackley, 1996). tourism connected with wildlife emerged from the natural surroundings. animals and plants play a major role in shaping mailto:mdabhalim09@gmail.com global sustainability research global scientific research 62 the attractions of nature. national parks, game reserves, wildlife sanctuaries, zoos, and aquariums are a few examples of attractions where wildlife makes it a destination. adventure in nature and wildlife tourism are getting popular day by day in bangladesh and all over the world. exciting forest camping, thrilling mountain hiking, rousing ecotourism, amazing safari park experience with animals etc. are few examples of wildlife tourism attractions. these serve as tourists' primary travel destinations in many countries like kenya, tanzania, zimbabwe, india, australia, ecuador and so on. throughout the world, wildlife viewing is a unique and captivating activity. people's exhilaration when seeing marine animals and other creatures can be inspiring. witnessing these animals in their natural habitats is an amazing experience and can inspire individuals to take a more active role in preserving the environment. since tourism exclusively depends on its clients, building a devoted clientele requires a sizable financial and marketing effort (raihan, 2023; sharma and upneja, 2005). the chance of revisiting is highly affected by visitor satisfaction. effective word-of-mouth advertising could be cheaper and more effective than other forms of promotion (dharmaratne et al., 2000; roy et al., 2021). for tourists to enjoy an unforgettable experience of observing wildlife without compromising the well-being of the animals they are seeing in the wild, observation techniques must be tightly controlled and maintained for tourists to enjoy an unforgettable experience of wildlife viewing to develop and expand. authorities and other tourism-related organisations must collaborate to reduce the impact that tourism has on wildlife and to guarantee the long-term sustainability and viability of the sector. seeing wildlife encompasses a diverse array of different species in varying places; some species are simple to find, while others pose challenges and costs for visitors. the type of activity and venue, along with the level of service and cost available to tourists, determine where and how to view wildlife. planning carefully, wildliferelated tourism can present a number of possibilities, foster social development, and boost revenue and support for the preservation of wildlife (tapper, 2006; deb et al., 2022a). in order to boost this industry, this study emphasises how visitors view wildlife tourism and offers ways to draw in more travellers. the study will explore ways to improve current practices while examining the primary factors affecting tourist attitudes toward wildlife attractions. bangladesh is a nation in south asia with stunning landscapes, distinct wildlife, and a unique climate. bangladesh offers a plethora of alluring locations for sightseeing that draw more visitors. one of the primary forces behind bangladesh's economic expansion could be tourism. if efficiently planned and effectively executed, wildlife tourism has potentials to emerge as an essential component of bangladesh's tourism economy. many nations use it as one of their most efficient economic growth and diversification instruments. for instance, many nations, including brazil, australia, costa rica, and few african countries like zimbabwe, kenya have backed and promoted wildlife tourism, which has contributed positively in their exponential economic growth. there has been a dearth of research on visitors' attitudes and perceptions regarding wildlife tourism (mariki et al., 2011; bitanyi et al., 2012; nafi & ahmed, 2017). most of the research emphasises on the nature and aspects of wildlife tourism (reynolds and braithwaite, 2001; newsome and rodger, 2012); community involvement in wildlife tourism (ashley and roe, 1998) and social impact of wildlife tourism (rodger et al., 2009). however, there are only a few studies on visitor attitudes and perception about wildlife tourism. in the bangladesh context, no research has been done on wildlife tourism and tourism development. the findings of this study will be beneficial to the tourism and travel arena since they will shed light on visitor requirements and behaviour as well as ways to harness wildlife's natural assets to draw in more visitors. this study's primary goals are to assess visitor satisfaction in this particular market category and determine the potential of wildlife tourism in bangladesh. the objectives of this study are to: a) find out the current and potential factors that influence tourists' satisfaction in bangladesh; b) examine wildlife management schemes in designated areas in order to boost visitor satisfaction, develop sustainable wildlife, and create jobs; and c) find out ways to deal with possibilities and obstacles that might arise in the future and gauge tourists' satisfaction with their wild encounters. global sustainability research global scientific research 63 literature review tourism is a kind of growth that elicits significant transformations in the socio-economic circumstances of those residing in the host location. tourism has led to significant improvements in the conservation of animals and vegetation. a prime origin of a foreign currency depends on wildlife tourism (reynolds & braithwaite 2001), as the majority of tourists prefer nature-based destinations as their travel attraction. according to the definition provided by the united nations environment programme (unep), wildlife viewing tourism refers to a specific kind of tourism that is systematically arranged and pursued with the primary objective of seeing or encountering various forms of wildlife and this form of tourism primarily encompasses non-consumptive activities centred on wildlife, such as seeing animals, sometimes engaging in tactile interactions, and providing sustenance, as opposed to consumptive practices like hunting and fishing (unep, 2006, pg. 12). wildlife tourism, also known as naturebased tourism, is the practice of engaging in tourism activities primarily inside designated conservation zones, whereby visitors are offered the unique chance to see and capture photographs of untamed fauna in their undisturbed ecological settings (unwto, 2014), where sharing photographs on social media like facebook, instagram etc. will affect the decisions of other tourists to travel those attractions (halim, 2022). in 2012, the government of bangladesh did a commendable job by announcing wildlife act to protect and support both wildlife and forests. the law has wildlife friendly directives including strict sections having provisions of severe punishment against crime related to poaching, hunting, killing, injuring, or damaging any part of a wildlife body, including migratory birds (wildlife act, 2012). the 2010 national tourism policy emphasises the planning and development of wildlife tourism through proper management. the 1972 bangladesh parjatan corporations (bpc) ordinance also identified and accentuated the development of wildlife tourism in different ways. in addition to the bangladesh wildlife law 2012, the article 18 (a) of the constitution of bangladesh states that the conservation of biodiversity is a legal obligation for all citizens of the country, which can significantly support the evaluation of this industry. visitor interest in wildlife varies widely, from scientific study to entertainment value, and can change over time (çetı̇nkaya & öter, 2016). wildlife tourism usually refers to interacting with habitat or uninhabited animals in the wild or nature and captivity (newsome et al., 2005; tapper, 2006; hvenegaard, 2006). wildlife tourism is carried out to find nondomesticated fauna inhabiting their natural ecosystems, which mainly involves non-consuming interaction with wildlife, such as observing and capturing images of animals in their undisturbed ecological environments (tapper, 2006; newsome et al., 2005; reynolds & braithwaite, 2001) and activities such as sport hunting, trapping, and fishing (reynolds & braithwaite, 2001). wildlife tourism, especially in some cases, is an activity shaped by imagination and untouchable. commonly paired with wildlife safaris are various activities, such as adventure sports, fishing, cultural heritage exploration, and other nature-centric pursuits (unwto, 2014). there is no guarantee that the core species will be seen. however, five factors are derived for the enjoyment of wildlife tourism, such as seeing animals in their indigenous environments, observing a diverse array of creatures, engaging in close proximity interactions with untamed fauna, exploring the concept of feeling of location, and exchanging experiences with others (curtin, 2005). reynolds & braithwaite's (2001) research entails a comprehensive examination of wildlife tourism, focusing on six key elements that contribute to the overall quality of the experience. these criteria are intensity, reliability, originality, species recognition, species situation, and length. nevertheless, to guarantee the achievement of sustainable development in the realm of wildlife tourism, it is essential to assess tourists' happiness with visitors' own experiences. visitor satisfaction or dissatisfaction is contingent upon three primary elements: the quantity and variety of fauna, the volume of transports and tourists, and the expertise and proficiency of guides and drivers (egresi & prakash, 2019). tourist satisfaction is also global sustainability research global scientific research 64 connected with the support for tourism development. tourists are more likely to support tourism development when they receive social, economic, and environmental outcomes from the tourism business (halim et al., 2022). tourism is an amalgamation of various needs or desires that can influence travel frequency (o'leary & deegan 2005). charm alone does not determine motivation; some people are driven by the desire to preserve or consider biodiversity in general rather than just charismatic species (hausmann et al., 2016). wildlife tourism entails engaging in activities that involve exploring natural environments and observing wildlife (cloke & perkins, 2005; curtin, 2013). internal driving must be removed from the immediate surroundings without incident, the push, pull, and external factors that attract more visitors to certain places (iso-ahola, 1982; dann, g.1977). a travel destination can be rated differently depending on the judgment (orams, 2002; tam, 2012), a contrast between expectations before and after the trip (çetı̇nkaya & öter, 2016; truong & foster, 2006). studies have shown that happy tourists are likelier to recommend places to their friends and return for another visit (gonzález et al., 2007). the tourist with excellent travel experiences and high satisfaction with the characteristics of the destination is more likely to be a loyal tourist who revisits the destination. tourists have positive experiences with products, services, and other resources provided by travel destinations that help create positive word of mouth (hughes et al., 2005). wildlife tourism is strongly influenced by the attitudes of tourists towards travel destinations. when tourists have a positive attitude, they are more likely to revisit the destination, discouraging others from visiting. perception is closely related to an attitude that explains and organises the sensation to create a meaningful experience so that it can thoroughly examine and integrate visitors' perceptions, along with the various factors that impact their existing perceptions of protected areas, into forthcoming management strategies aimed at attaining conservation objectives. (jones et al. 2011). because of how conservation works, managing protected areas can be challenging because they have to meet both nature conservation and visitors' needs. it can be maximised by understanding the broad differences between attitudes and perceptions of an inconsistent tourist population and examining their long-term effects on nature conservation and the development of the tourism industry (suckall et al. 2009). egresi and prakash (2019) explained that explaining visitor expectations can be part of your animal experiences, as a reasonable interpretation of the quality goes a long way towards visitor satisfaction. several studies have shown that analysing data on interactions with or views of wildlife effectively may increase public support for wildlife conservation. wildlife tourism measures economic growth with positive social-environmental benefits. visitor happiness is essential in promoting, planning, and developing tourism items within a vacation location (yoon and uysal, 2005). understanding the attributes of the target that increase loyalty provides merchants and target managers with helpful information to scale the success of their marketing strategy and build strong loyalty (kweka, 2004). wildlife tourism creates opportunities for the community and helps conserve endangered and endemic species and their habitats, thereby benefitting the economy of the host country. the economic advantages of wildlife tourism may have extensive implications when there is an efficient establishment of tourism goods, services, and value chains designed to encourage visitors to use their funds on-site (lickorish & jenkins, 2007). tourism transactions with providers of tourism services and products such as accommodation, food, recreational activities, transport, ticket prices, duties, travel guides, and gifts; tourism concessions and leases, together with volunteers and donations, may also constitute significant contributions (font et al., 2004; goswami et al., 2019). tourism stimulates other economic sectors through its demand for products and services, services from other local sectors (such as agricultural producers), and families' increased spending on local goods and services. locals' attitudes have a significant role in determining the success of the tourist business (raihan et al., 2022; yoon et al. 2001), as residents' negative attitudes towards tourism can affect the success of the tourism industry. global sustainability research global scientific research 65 tourism can have positive effects such as employment opportunities, prosperity, effectiveness, and improvement of income and infrastructure, strengthen the international friendship between people and provide the local community with assets that enhance the perception of the local population, which can change population-based wildlife tourism (tosun, 2002). on the other hand, the increase in tourism activity benefits environmental quality since the most popular tourist destinations worldwide prioritise adopting clean energy technologies and promoting ecotourism in the long term (rahman et al., 2022). wildlife tourism is a distinct sector within the broader tourist business and is recognised as a lucrative global enterprise (rodger & moore, 2004; reynolds & braithwaite, 2001). however, it has been observed that there is a dearth of scholarly investigations about this particular domain. visitor satisfaction or attitudes may vary due to factors affecting the visitor's perception of wildlife. figure 1: key factors influence tourist behaviour although inconsistent behaviour can be caused by various factors such as knowledge, which is seen as a critical determinant of human behaviour (la barbera et al. 2016), traditional culture, social norms, and customs within the family determine a person's behaviour or attitudes person (kollmuss & agyeman 2002; voumik et al., 2023b). individuals can be irrational and characterised by social and institutional constraints with gaps between the "value-action gap" (blake, 1999). the psychological and sociological satisfaction process underlying human and animal relationships is necessary for understanding wildlife tourism (newsome et al., 2005; dey et al., 2019; deb et al., 2022b). the wildlife tourism experience has been shown to have favourable benefits on tourists' environmental behaviour, resulting in long-term improvements. in exploring the human dimensions of interactions with wildlife, humans need contact with nature, and an emotional bond with wildlife could play an essential role in motivating environmentally friendly behaviour. in contrast, motivational forces like enjoyment and seeking to organise budget tours among young bangladeshi tourists (roy et al., 2021) may drive them to choose travel options which is less environmentally friendly. methodology the investigation provides the researcher insights into the problems or situation of the research. in order to collect personal behaviour satisfaction value-chain culture factors affect the tourist behaviour global sustainability research global scientific research 66 information from the tourists, a structured questionnaire was designed. in the tourism and hospitality industry, people are more willing to fill in questionnaire forms due to the ease and absence of long open questions (brace et al., 2004). a structured survey was conducted using questionnaire forms where the entire questionnaire was divided into two parts consisting of twenty questions; the first consisted of questions on the respondents' sociodemographic characteristics, and the second consisted of questions on tourists' perception of wildlife tourism in bangladesh. the questionnaires were distributed and collected from tourists choosing the wildlife destinations in bangladesh, i.e., zoos, safari parks, eco-parks, sundarbans, and other places. a google forms survey questionnaire was created and posted on the social media to collect data. travelers were asked to fill out the form as respondents based on their experiences visiting wildlife destinations. the survey was conducted between february 25 and march 10, 2023; this week-long survey was completed in english first and translated into bengali to better understand the respondents. the second part of the questionnaire used a five-point likert scale in which respondents were asked to rate their satisfaction with each point on a five-point likert scale. the method of administration was used to analyse the quantitative approach that explains the theoretical assumptions to be understood. almost 250 questionnaires were distributed among different groups of people to collect data. after collecting data 207 questionnaires were selected for further analysis. spss 20.0 software was used to get the statistical analysis. this study used quantitative methods to collaborate the data collected through primary and secondary sources. the sociodemographic features of the respondents were scrutinised using statistical methods such as frequency, mean, standard deviation, and percentage. the link between independent and dependent variables was examined using multiple linear regression and pearson correlation. a p-value below 0.05 was deemed significant. findings and discussion this section of the study presents the survey data with regression analysis, reliability tests, hypothesis tests, and descriptive statistics. demographic profile of the respondents however, the summary of the socio-demographic information of the respondents are given in table 1. however, 64 per cent of the respondents have previously visited wildlife tourism destinations in bangladesh. the results gave a total of 207 respondents (approx.), with 39.1 per cent male and 60.9 per cent female. the results also showed that 40.1 per cent of those surveyed are students, 21 per cent of those surveyed are service providers, 15.5 per cent of respondents are business people, and approximately 22.7 per cent are from other professions. most respondents were, 46.9 per cent, between 25 and 37 years old, while 17.9 per cent were younger than 38 to 50 years. the age group and occupations of the respondents were mainly service providers or students, which means that they were not regular visitors but occasionally visited these destinations; it also shows that most visitors are for educational or entertainment purposes. global sustainability research global scientific research 67 table 1: respondents demographic profile frequency percentage valid percentage yes 133 64.3 64.3 no 74 35.7 35.7 total 207 100.0 100.0 male 81 39.1 39.1 female 126 60.9 60.9 total 207 100.0 100.0 1224 years old 19 9.2 9.2 25-37 years old 23 11.1 11.1 38-50 years old 98 47.3 47.3 51-73 years old 38 18.4 18.4 74 years old or older 29 14.0 14.0 total 207 100.0 100.0 student 83 40.1 40.1 service-holder 32 15.5 15.5 business 45 21.7 21.7 others 47 22.7 22.7 total 207 100.0 100.0 010 thousand 92 44.4 44.4 1020 thousand 30 14.5 14.5 2030 thousand 21 10.1 10.1 3040 thousand 37 17.9 17.9 above 40 thousand 27 13.0 13.0 total 207 100.0 100.0 source: survey data descriptive statistics table 2 shows the descriptive statistics of the study. this table shows the mean score, standard deviation, and variance of all factors. the table shows the overall positive perception of travellers on wildlife tourism. respondents express that wildlife tourism can help to enrich knowledge which gets highest mean score followed by adventure facilities, services at destinations, transportation facilities, recreation facilities, trained employee, reasonable price of services, and rich beauty of the destination area. after that, respondents express their moderate expression about recreation facilities at the destination, proper security systems, hygiene system at destination area. global sustainability research global scientific research 68 table 2: descriptive statistics statement n mean std. deviation variance liked the spot because of its rich scenic beauty. 207 3.7681 1.39150 1.936 the place was clean, comfortable and maintains hygiene. 207 2.9082 1.31691 1.734 the area ensured proper security. 207 3.1159 1.11307 1.239 recreational amenities were not available and convenience. 207 3.0903 3.84151 14.757 the price of locations products or services was very much reasonable. 207 3.8357 1.27412 1.623 preferred the spots to exploit the wildlife of animals. 207 3.9469 1.27030 1.614 venue service was very good to expand amusement. 207 4.0145 1.25210 1.568 the site had good transportation facilities. 207 3.9108 1.17675 1.385 services provided at promised time. 207 4.1256 1.20825 1.460 received an unforgettable adventure while visiting the venue. 207 4.1159 1.15165 1.326 felt the shortage of spot operator's service. 207 4.0580 1.17272 1.375 staffs were well trained. 207 4.1111 1.24722 1.556 while providing service, there was discrimination against different tourists. 207 3.81 1.16531 1.358 touring the site can enrich the knowledge about wildlife. 207 4.26 1.1276 1.258 source: survey data regression analysis the relevant factors in the regression equation were observed as a function of the beta coefficients in order of importance. the multiple correlations (r), the determinant (r2), and the quotient f are examined to predict the quality of the regression model. the value of r related to autonomous factors and the dependent variable is .544, which shows that tourists have a positive perception of wildlife tourism; showed that the value of r2 is 0.296, indicating that fourteen variables explain more than 50 per cent of the variance, which explains tourists' perception of wildlife tourism services. the adjusted r-square shows that 0.245 is the local community, and tourists had positive and moderate correlations in wildlife tourism. table 3: model summary model r r square adjusted r square std. the error of the estimate 1 .544a .296 .245 .98474 source: survey data global sustainability research global scientific research 69 table 4: anova model sum of squares df mean square f sig. regression 78.461 14 5.604 5.779 .000b 1 residual 186.186 192 .970 total 264.647 206 source: survey data table 4 displays, as a result of the analysis of variance (anova), the p-value is .000, which is less than the significance level of .05, about 54 per cent. in other words, at least one of the factors is essential to contribute to wildlife tourism. the importance of the factors is analysed in the coefficient tablet, which represents all of the study variables. table 5: coefficients model unstandardised coefficients standardised coefficients t sig. b std. error beta (constant) 1.637 .415 3.943 .000 liked the spot because of its rich scenic beauty .032 .056 .039 .572 .568 the place was clean, comfortable, and maintain hygiene. .179 .072 .208 2.470 .014 the area ensured proper security. -.191 .074 -.188 -2.582 .011 recreational amenities were not available and convenient. -.018 .053 -.023 -.342 .733 the price of locations products or services was very much reasonable. -.032 .066 -.035 -.479 .633 preferred the spots to exploit the wildlife of animals. .111 .071 .124 1.560 .020 venue service was very good to expand the amusement -.066 .065 -.073 -1.022 .308 the site had good transportation facilities .185 .073 .193 2.529 .012 services provided at the promised time. -.057 .076 -.061 -.759 .449 global sustainability research global scientific research 70 received unforgettable adventure while visiting the venue .135 .075 .138 1.811 .042 felt the shortage of spot operator's service -.005 .067 -.005 -.067 .947 staffs were well trained. .036 .069 .040 .527 .599 while providing service, there was discrimination against different tourists. .089 .074 .092 1.211 .228 touring the site can enrich the knowledge about wildlife. .231 .072 .229 3.218 .002 source: survey data table 5 displays, tourist perception towards wildlife tourism services = 1.637+ .032 (scenic beauty) + .179 (hygiene of spot) + (-.191) (security of place) + (-.018) (amenities) + (-.032) (price) + .111 (exploiting spot) + (-.066) (venue service) + .185 (transportation)+ (-.057) (service time) + .135 (unforgettable adventure) + (.005) (shortage of service ) + 0.36 (well-trained staffs)+ .089 (discrimination with tourist) + .231 (enriching knowledge) this equation shows that all the critical success factors are not similar importance to measure tourist perceptions towards wildlife tourism. the significant critical factors identified from the regression result are as follows: enriching knowledge (.002), security of place (.011), transportation (.012), hygiene of spot (.014), and unforgettable adventure (.072) are highly significant for measuring visitors perceptions towards wildlife tourism. ho (null hypothesis): there is no clear correlation between destination attributes and tourist perceptions towards wildlife tourism. h1 (alternative hypothesis): there is a clear correlation between destination attributes and tourist perceptions towards wildlife tourism. in the finale, all the factors are not equally significant but greatly affect the dependent variable. thus, the results of multiple regression analysis accept h1 (alternative hypothesis): "there is a clear correlation between destination attributes and tourist perceptions towards wildlife tourism". so, the null hypothesis is rejected, and the alternative hypothesis has been accepted. reliability of the study in order to measure the reliability of the perception of tourists towards wildlife tourism, the internal consistency test of cronbach's alpha was included in the questionnaire. this test also measures that respondents answer the consistency of all elements used in the questionnaire. "several values for alpha calculations in the chronbach area fell to acceptable values of 0 or 0.6 in a national or international study" (van griethuijsen, 2015). global sustainability research global scientific research 71 table 6: reliability statistics cronbach's alpha cronbach's alpha based on standardised items no of items .764 .839 14 source: survey data table 6 illustrates cronbach's alpha scale as a measure of reliability. the value is 0.839, which means the study is standard and reliable. the proposed cronbach alpha above 0.70 is taken into consideration as ideal (bonett and wright, 2015). therefore, analysing the size of the traveller's notion of natural world tourism has positive, dependable, and ideal effects. recommendations some specific recommendations are given below: • wildlife management should enhance visitor amenities like campgrounds, restrooms, and rest areas. according to the findings, visitors concurred that higher-quality improvements should be made to the facilities for visitors. these facilities need to be improved to improve the quality of the tourist experience and encourage return visits. • the bangladesh tourism board, bangladesh parjatan corporation, and the ministry of civil aviation and tourism should collaborate to enhance the marketing plan. in addition to the current website, using social media platforms like instagram, facebook, and twitter is a good marketing tactic that can be used. in a short time, social media can reach more potential travellers. • the authorities and stakeholders should guarantee that visitors receive the highest calibre services to encourage positive word-of-mouth. when visitors come to our national parks and receive excellent service, they will return home with positive recommendations. proper carrying capacity must be maintained strictly in the destination area. • bio-diversity and natural resources should be adequately maintained to ensure the destination's sustainability. conclusion in this study, several interesting conclusions can be drawn from the outcome of the research, with the hope that future research will increase understanding of tourist behaviour in wildlife tourism, as the current study showed an excellent future for wildlife tourism where tourists are delighted and interested in wildlife tourism. the previous results showed that the likelihood of wildlife tourism is high as it is still growing and needs an adequate management and management committee to regulate its programs precisely. although wildlife tourism attracts many visitors, there are still not many people who visit wildlife. the challenge of wildlife tourism today is to develop pragmatic marketing strategies to attract more tourists. wildlife operators need to make appropriate connections with other types of attractions to maximise exposure. developing a code of conduct and a standard operating procedure (sop) can be a good strategy. the operators are aware that customers carefully check their operations for environmental protection, sustainable practices and ethical systems. a code of conduct for the industry would be precious, especially if it were developed by the industry participants themselves (cooperative research centre, 2009). global sustainability research global scientific research 72 many researchers have identified multiple goals and areas for future wildlife industry benefits improvement. first and foremost, local investment should be the focus of interest, as, without local involvement, a conflict continues to grow and only poses a threat to this industry. second, the problems between tourism development, ecology, and local population in and around the location of wild animals need to be resolved. this should be achieved through collaboration between locals, park rangers, conservationists, and tour operators when arrangements are made to meet all interests equitably. in addition, roads and means of transport need to be expanded, updated, and improved to allow adequate access to many parts of the country that are isolated and inaccessible. third, the infrastructure across the country needs to be improved, for example, the energy and water supply, since, in addition to poor water quality, inconsistencies in the provision of these resources can occur (smiley, 2016; banerjee & morelia, 2011). tourism can be a way of supporting the development of such infrastructure projects while providing support for and through tourism. this study evaluated the variables influencing visitors' attitudes and perceptions of bangladeshi wildlife tourism. in summary, the significance of characteristics, effectiveness, attitude, and drive function to gauge visitor contentment and jointly impact overall satisfaction in wildlife destinations. visiting experience was assigned to the categories of motivations. this study is conducted using various internet panels and may have errors or limitations. wildlife tourism is a huge industry and has the potential to boost economic growth in bangladesh. some residents feel that wildlife tourism has not yet brought sufficient economic benefits to the local population. many researchers have high hopes and positive prospects for developing wildlife tourism in rural areas, although some have been concerned about undesirable cultural effects and social degradation. however, the operators of this industry need to remember not to focus solely on profits, which may not be the only reason for animal conservation. using a market-oriented protection strategy implies that these animals and their habitats can only be saved if they are profitable, which is a cruel judgment of the operators. tourism should be declined, which would put these animals at risk again (mccauley, 2006). wildlife tourism is a specialised aspect and a niche of nature-based tourism. wildlife tourism is about exploring the great outdoors and raising awareness of different types of wildlife. in the future, wildlife tourism needs more research and guidance from tourism researchers and institutions that provide more opportunities to expand the branches of wildlife tourism and achieve success. policymakers need to ensure that proper security systems are in place to develop wildlife tourism in bangladesh. at the same time, wildlife conservation is also significant for tourism. it will call for and offer an action plan to use potential wildlife resources to attract more tourists. this research will benefit the bangladeshi wildlife tourism industry, as hardly any study has been conducted specifically. hopefully, this study will open new avenues for researchers to explore and analyse the immense potentiality of wildlife tourism in bangladesh in the coming days. this research was conducted to measure the perception of visitors about wildlife tourism in bangladesh, and there are some limitations. in this study, parameters related to tourism and tourism-related services are considered for calculations. however, the perception and attitude of the local community, tourism stakeholders and policymakers should be the prime concern for the future studies. declaration acknowledgment: we express our sincere gratitude for the significant efforts and assistance provided by all persons who contributed to the successful completion of this study. funding: authors self-funded research global sustainability research global scientific research 73 conflict of interest: the authors declare no conflict of interest. authors contribution: conceptualization, s.h., m.a.h., s.m.n. and m.r.a.;

children ever born; food insecurity; lideta sub-city; addis ababa; ethiopia introduction the world's population has experienced a remarkable increase, growing from 1 billion in 1800 to a staggering 8 billion today. the less developed countries of africa, asia, and latin america now account for 85 percent of the world's population but account for 99 percent of global population growth (united nations, 2022). the highest fertility rates and higher childhood mortality rates are found in the poorest and most food-insecure countries (boliko, 2019; fao, 2020). surprisingly, the world is still home to over 800 million undernourished people, over 97% of whom live in developing countries. the rate of undernourishment worldwide is on the rise, affecting 9.9% of people globally (fao, 2021). global sustainability research global scientific research 31 sub-saharan africa, with a population of 1.3 billion (17% of the world population), has by far the fastestgrowing population of any major region in the world (united nations, 2022). despite significant advancements in reducing child mortality and enhancing life expectancy, reproductive health among women residing in developing nations, particularly in sub-saharan africa, remains insufficient, leading to persistently high birth rates. on average, women residing within the region have about 4.26 children (united nations, 2022). the widespread adoption and utilization of family planning methods have become instrumental in mitigating the growth of the population as well as addressing the issues of hunger and malnutrition (smith & rhonda, 2015). ethiopia remains one of the world's most impoverished and food-insecure nations, with 30.8% of its population living below the poverty line for sustenance (odekon, 2022). the majority of urban households in ethiopia, comprising approximately 80%, exhibit food insufficiency and rely heavily on market mechanisms to procure their food requirements (wfp/unicef, 2019). following the interim report on poverty analysis study in ethiopia (fdre, 2017), there was an estimated 14.8% proportion of the population in urban areas categorized as being below the food poverty line. in addis ababa, the estimated proportion of individuals experiencing food insecurity, defined as those unable to purchase consumption items that yield a minimum of 2,200 kilocalories, is 19.1% (pdc, 2019). similarly, the proportion of people suffering from food insecurity in the lideta sub-city, which is considered to be one of the most deprived sub-cities in addis ababa, was estimated at around 29.3%. this means that about one-third of the population falls below the threshold of adequate food intake (mofed, 2018). the share of total household income spent on food is around 42.2% (csa, 2016b). urban food insecurity is mostly chronic, combined with higher urbanization rates, food price changes, and market instability (boliko, 2019; riley et al., 2019), and persists for long periods, if not lifetimes (fao, 2020). it is closely associated with urban poverty. as the study conducted by belachew et al. (2012) in ethiopia showed, chronic food insecurity in households can result in persistent malnutrition as a consequence of the inability to secure adequate and sustained access to food. in situations where there is a surge in food prices, households that do not engage in food production, particularly those located in urban areas, are compelled to procure food through alternative means, predominantly through purchase. the purchasing power of households is contingent upon their income, so a rise in the prices of food can have adverse effects on their ability to access sufficient amounts of food (boliko, 2019). indisputably, households experiencing poverty typically encounter a plethora of challenges, such as unfulfilled family planning demands, families with sizes that exceed their preferences, and inadequate financial resources to afford the necessary quantity and quality of nourishing sustenance to meet the needs of their families. the condition of poverty precipitates inadequate access to family planning and, in turn, serves as a consequence thereof. families with lower economic status experience limited availability of family planning services. they allocate a greater portion of their budget towards sustenance while expending a lesser amount of money per individual on food as opposed to affluent households (smith & rhonda, 2015; usaid, 2014). though the total fertility rate in addis ababa is relatively better compared to other regions of ethiopia and is estimated at 1.8 children per woman, the fertility rate is still high at the national level, which is 4.6 children per woman (csa, 2016a). a crucial consideration towards maintaining sustainable population growth that does not burden the world's finite resources needs foremost attention to the interrelationship between food security and reproductive health (khatun & mallick, 2020). literature review economic, social, and religious factors like income, education, religion, work status, age at first birth, age at first marriage, contraceptive use, and childhood mortality affect fertility (demeke et al., 2011; dieu, 2016; global sustainability research global scientific research 32 masoud, 2009; mekonnen & worku, 2011c; ojakaa, 2008; rabbi et al., 2013; tomkinson, 2019). among the various theories of population and fertility, neo-classical microeconomic theory (becker & lewis, 1973) and demographic transition theory (notestein, 1953) are considered the most useful in examining the interrelationship between food insecurity, fertility, and contraceptive use. these theories center on the principal determinants that are responsible for the elevated fertility rates observed in developing nations. this phenomenon is commonly attributed to a dearth of economic advancement. according to demographic transition theory, high infant and child mortality, poor agricultural productivity, insufficient utilization of contraceptives, and a relatively lower socioeconomic standing in terms of women's education, occupation, and social status contributed to the high fertility norm. some empirical studies have also confirmed that food insecurity and fertility are related. the study conducted by mekonnen and worku (2011) in butajira district, south central ethiopia, showed that food security is a significant predictor of the effect of having fewer children. the findings of the study indicate that women residing in food-insecure households exhibited a 6% increase in the number of children ever born relative to women inhabiting food-secure households. another study conducted by diclemente et al. (2021) in tanzania also showed that food insecurity is positively related to the fertility experience of households when controlling education, place of residence, age of the mother, and number of living children. according to the finding, women who experience household hunger exhibit a higher likelihood of desiring additional children or expressing uncertainty about having more children in comparison to their counterparts who do not experience household hunger. this finding highlights the potential impact of food insecurity on reproductive decisionmaking among women. the study undertaken by abdu et al. (2018) in the assayita district of the afar regional state in ethiopia has demonstrated a significant correlation between household food insecurity and household fertility. the results of the study indicate that households characterized by a parity of five or more children were found to exhibit a significantly greater likelihood of experiencing food insecurity when compared to those who had not yet born children (parity 0). according to this study, women who have two or more children under the age of five are at a statistically significant increased risk of being underweight due to malnutrition, with odds greater than nine times that of women without young children below five years of age. although various studies have been conducted to show the effects of food insecurity on child health and development (kimbro & denney, 2015; quyen et al., 2014), education performance, and intellectual development (belachew et al., 2011), external and internal behaviors (murphy et al., 1998), and stunting, wasting, and underweight (abdu et al., 2018; abdurahman et al., 2016; berra, 2020; betebo et al., 2017; diclemente et al., 2021), insufficient emphasis has been placed on investigating the relationship between urban household food insecurity and demographic outcomes within scholarly discourse. undoubtedly, endeavors have been made to elucidate the correlation between women's reproductive health status, fertility, and the household's food security (abdu et al., 2018; feyisso et al., 2015); however, scant attention has been given to elucidating the reciprocal relationship between food security, fertility, and family planning. this study aims to investigate the relationship between urban household food insecurity and fertility, providing policymakers and development stakeholders with valuable insights to guide well-informed decision-making and effective interventions. methodology study design and area a cross-sectional study design was used to collect data from february to march 2023 in lideta sub-city, located in the central-western area of addis ababa. borders are shared with addis ketema, arada, kirkos, nifas silkglobal sustainability research global scientific research 33 lafto, and kolfe keranio. the sub-city is divided into ten woredas. the study randomly selected three woredas and collected data at respondents' residences in the sub-city. lideta sub-city covers 9.18 sq km with a population of 284,208, including 134,372 males and 149,836 females. the study focuses on a highly populated and poor district in addis ababa with a population density of 30,960 people per square kilometer (csa, 2022b). sampling design and procedure sample size was determined by the single mean formula proposed by bartlett et al. (2001) with the assumption that the single population proportion experiencing food insecurity is often estimated to be 50%, with a margin of error of 5% and a 95% ci (z1/2 = 1.96). a design effect of 1.5 for cluster sampling and some allowance were also added, considering the variability in the study population and controlling non-response rates and outliers, respectively. the sampling strategy of this study was operationally predicated on the pre-established enumeration areas of the sub-city, which had been delineated by the central statistical service of ethiopia. samples are drawn from a population using a multi-stage random sampling technique. in multistage random sampling, three woredas are randomly selected at the first stage. secondly, each woreda comprises different ketenas (villages), and from each of these three woredas, two ketenas are selected using the random sampling method. in the last step, a total of six ketenas were there to select the final 649 respondents. the total sample, which was selected using a multi-stage random sampling technique, was divided among all those woredas and then among ketenas proportionally to their population. the households from the respective woreda were selected by systematic random sampling based on a sampling frame of house numbers developed from ketena records. individual respondents of women within the age range of 15 to 49 years who would be either household heads or spouses and gave birth within the last 15 years preceding the survey were sampled. if the selected household was found to be closed, the household with the next number on the list was selected, and this continued until the required number of sampled women was acquired. study variables the outcome variable of this study is fertility. it refers to the reproductive performance of an individual, a couple, a group, or a population, which could be measured by using the number of children ever born, the consecutive birth interval, or the total fertility rate. here, fertility is measured by taking the number of children ever born (ceb) as a discrete outcome variable. predictor variables and covariates include household food insecurity status and other demographic and socioeconomic variables such as the age of the mother, marital status, women's education, women's income, religion, work status, age at first birth, contraceptive use, the desired number of children, and childhood mortality. analytical methods the relationship between urban food insecurity on fertility will be analyzed using the poisson regression model taking children ever born as dependent variables and food insecurity as the main predictors. more formally, the poisson regression model will be expressed as 𝑙𝑜𝑔(𝜆𝑖) = 𝛽0 + 𝛽1 𝑋𝑖1 + 𝛽2 𝑋𝑖 2 + . . . + 𝛽𝑛 𝑋 𝑖𝑛 + 𝑢𝑖 ) global sustainability research global scientific research 34 λi is the number of children for women in the lideta sub-city, xi is a vector of k characteristics, 𝛽o is the intercept, 𝛽 is the vector of covariate parameters, and ui is the error term. the present study shows the outcomes of the model, which reveal the incidence rate ratio or exp(ß) , elucidating the relative change in the number of children given a unit change in the explanatory variable, while keeping all other variables constant. the present study employed a poisson regression model to evaluate the association between household food insecurity and the number of children ever born, along with several other independent variables. descriptive statistics, on the other hand, will help to give bivariate analytical results for the study. the data was collected using kobocollect 3.5 and entered into the spss 24 software with caution. the completeness and errors related to inconsistencies were verified using the data cleansing method. bivariate analysis was employed to identify the variables that exhibited a statistically significant association with fertility. in this study, the variables that exhibited a p-value of less than 0.25 were subjected to a thorough examination for multicollinearity issues utilizing the variance inflation factor (vif). following this preliminary assessment, the identified variables were included in the poisson regression model to determine their effect on the outcome variable (children ever born). incidence rate ratios with their corresponding 95% confidence intervals were computed. a significance level of 0.05 was deemed statistically significant in the present study. measurement of household food insecurity the caloric value of foods that meet the threshold requirement of 2,200 kilocalories (kcal), as recommended by the food and agriculture organization (fao, 2004), for enabling healthy and moderately active adult living is determined by their corresponding national average prices to establish the food poverty line. although the 2016 interim poverty analysis report estimated the cost at 3,772 birr per year per adult person in ethiopia (fdre, 2017; mofed, 2018), this price is not feasible and had to be adjusted based on current food prices. however, the overall percentage of inflation has reached 122.2 % from june 2016 to january 2023; computing the amount of food inflation year by year brings the estimated cost to birr 11,524.52 per year per adult (csa, 2022a; nbe, 2022). accordingly, the cost of one kilocalorie is estimated to be birr 0.0143. in this article, the national food poverty line was used to measure food insecurity status. the food poverty line determines whether a given household can have enough daily food expenditure (total household income spent on food) to meet its members' minimum daily calorie needs. therefore, households that cannot afford the money or are unable to source consumer goods for these daily calorie needs are considered to be food insecure. however, individual access to food depends on household food distribution and gender parity, which in practice means that consumption patterns are not uniform (battersby, 2011). often, children, women, and older household members consume less food compared to those male adults (claro et al., 2010). a per capita adult equivalent estimate is obtained by dividing the total daily income or calories by all household members, assuming a uniform food consumption pattern for families with different compositions. therefore, if this adult person equivalent estimate were taken, birr 31.46/2,200 kcal would be used as a standard threshold to identify food-insecure households from those that are not. but such an approach could make households food-insecure that were almost certainly not insecure since they fail to consider the presence of household members with distinct energy needs. thus, in this article, an adult-equivalent estimate of the calorie availability scale that has an adult-equivalent conversion factor was used (appendix). the application of an adult-equivalent scale effectively narrows the variance between estimated and actual food intake, thereby enabling the discernment of the relative contributions of distinct household members towards the overall dietary pattern of the household, global sustainability research global scientific research 35 which is not feasible with the utilization of per capita metrics. household income and expenditure survey is standard and widely applicable to measure household food insecurity and poverty at the household level (abuelhaj, 2007; bellú, l. g. & liberati, 2005; ruggeri laderchi et al., 2003). the world bank, usaid, the international development association (ida), and the ethiopian government have applied this monetary approach to measure household food insecurity/poverty related to the urban productive safety net program in urban ethiopia (upsnp, 2021). moreover, the government of ethiopia and other developing countries have also applied this monetary approach to food poverty and insecurity analysis, identifying the prevalence, gap (shortfall), and severity of household food insecurity (fdre, 2017; pdc, 2019). results and discussion demographic and socio-economic characteristics of respondents as shown in table 1, a total of 649 households participated in the study. of these, nearly half, or 48.7%, are between 25 and 34 years old. of all respondents, single, married, divorced, and widowed account for 114 (17.5%), 432 (66.6%), 87

significant proportions of the survey participants (67.5%) were orthodox christians, 15.0% were muslims, and protestants accounted for 17.4%. the majority of respondents (50.4%) are not using any modern contraceptive method and 12.2% of respondents have at least a history of childhood mortality. the majority of respondents, around 72.5%, earn a monthly income of 0–3000 birr. regarding age at first birth, the majority of respondents (39.6%) started childbearing at the age between 20 and 24. moreover, measuring a household's food insecurity status also revealed that 68.3% of the sample households were food insecure and the remaining 32% were food secure. the relationship between food insecurity and fertility table 1 presents the mean values of children ever born among women, categorized based on food insecurity and socio-demographic characteristics. the findings of the survey indicate that households experiencing food insecurity exhibit a higher mean number of children ever born at 1.79 compared to those who are food-secure, with a mean number of children ever born of 1.14. the mean number of children ever born exhibits variance across various religious groups. according to the findings of the survey, muslims exhibited the highest mean number of children ever born, with a value of 1.89, followed by orthodox christians with 1.52 and protestants with 1.45. based on the findings of the survey, it was determined that women with monthly earnings ranging from 1,500 to 3,000 birr and 3,000 to 4,500 birr had a mean number of children ever born of 1.54 and 1.36, respectively. this result falls below the replacement level as it signifies that these women are not producing enough children to replace themselves. comparably, the number of children that have ever been born to individuals belonging to the high-income category (earning over 4500 birr per month) and low-income category (earning between 0 and 1500 birr per month) was determined to be 1.09 and 2.18, respectively. according to the findings, the mean number of children ever born to married women (1.87) was compared to those of unmarried, divorced, and widowed women, whose mean numbers of children ever born were 0.79, 1.18, and 1.75, respectively. these results suggest a significant association between marital status and the number of children ever born. in contrast, the findings indicate that females with no education and those holding degrees and above exhibit the greatest and least mean numbers of children ever born, standing at 1.48 and 1.42, respectively. concerning the demographic category of females, there is a positive correlation between maternal age and the mean number of children ever born. the findings indicate that women in the age bracket of 35 to 39 exhibits a significantly greater mean number of children ever born (2.00) in contrast to young women (1.03). factors of household fertility in lideta sub-city, addis ababa, ethiopia a bivariate analysis was conducted to ascertain potential variables for inclusion in the poisson regression. utilizing specific criteria, the variables of maternal age, marital status, women's income and work status, age at first birth, food insecurity, and childhood mortality were deemed suitable for inclusion in the poisson regression analysis. after adjusting for confounding factors, including maternal age, marital status, contraceptive use, and household food insecurity status, and childhood mortality, significant statistical associations were observed with fertility at p < 0.05 (table 2). efforts have been made to assess whether or not the necessary assumptions for the application of poisson regression are fulfilled. the present study compared the adequacy of two regression models, namely poisson and negative binomial, in explaining a given set of data by utilizing two popular model selection criteria, namely kaike's information criterion (aic) and the bayesian global sustainability research global scientific research 37 information criterion (bic). the results revealed that both aic and bic were lower for the poisson distribution than for the negative binomial distribution. this finding suggests that the poisson regression model represents a better fit for the data compared to the negative binomial regression model. conversely, the evaluation of model fit using the goodness of fit test reveals a deviance below 1, signifying that under dispersion is present and the value approaches zero. this result is indicative of zero inflation, thereby suggesting that the poisson regression model is best fitted. the utilization of an omnibus test in the poisson regression model has resulted in a significant p-value of 0.001, indicating that all predictor variables incorporated in the model are meaningful full predictors of the effect of the number of children ever born. table 2 : coefficients and odds ratio of fertility in lideta sub-city, addis ababa note: the reference group is listed in the parentheses. the result of the study shows that food security status was a significant predictor of the number of children ever born at p < 0.05. holding the other variables constant, the number of children ever born for women within foodsecure households is 0.655 times lower compared to women with food insecurity. as we can see from table 2 , women's monthly income was a significant predictor of the number of children ever born. holding the other variables constant, the number of children ever born for women with monthly incomes of 0–1500, 1500–3000, and 3000–4500 birr is 1.495, 1.287, and 1.236 times greater, respectively, compared to those women having an income of birr higher than 4500. this means that the reduction in income levels from birr 4500 and above to birr 3000–4500, birr 1500–3000, and birr 0–1500 is associated with increases in the number of children ever born by 23.6%, 28.7%, and 49.5%, respectively. the results of the study show that marital status has a significant effect on the number of children ever born. the finding indicates that single women have 0.601 fewer children compared to their widowed counterparts. a woman's age is one of the most significant biological and demographic factors affecting fertility. the present investigation indicates that there is a significant disparity in the number of children born by older women as compared to their younger counterparts, meaning that a younger age at first birth is associated with a higher number of children ever born. when comparing the number of children ever born across

scientific research 38 is evident that there is a decreasing trend as age decreases. specifically, the age group of 20–24 displays a low number of children ever born, whereas the age group of 35–39 exhibits a high number of children ever born. women belonging to the age groups of 20–24, 25–29, 30-34, and 35–39 have 1.359, 1.375, 1.682, and 1.646 fewer children, respectively, when compared with their counterparts in the 45–49 age brackets. the difference in the number of children ever born between contraceptive users and non-users was also found to be significant at p < 0.05. other factors being equal, the number of children ever born for contraceptive users is 0.833 times lower than for non-users. the history of child mortality and the need for children were also found to be significant predictors of the effect of the number of children ever born. holding other factors constant, women with childhood mortality experiences have 0.721 more children than women without childhood mortality experiences. discussion the present study endeavors to evaluate the association between food insecurity and fertility in lideta sub-city. according to the present investigation, the average number of children ever born to women of childbearing age in the study area is 1.58, which is below the replacement level. this finding was comparable with the study conducted in addis ababa, which was 1.9 births (gurmu & mace, 2008), but lower than what was reported in the ethiopian demographic and health survey at the national level (2.84 births) (csa, 2016a). the observed variability could potentially arise from differences in the demographic, socioeconomic, or cultural status of women or from other factors pertaining to health, such as disparities in counseling proficiency (shiferaw et al., 2019). the findings of the study also show that the number of children ever born from food-insecure households was higher compared to children from food-secure households. this finding was consistent with some studies (diclemente et al., 2021; feyisso et al., 2015; mekonnen & worku, 2011a). the plausible explanation for this phenomenon is that children residing in households experiencing food insecurity are perceived as contributing meaningfully to enhancing the socio-economic status of their family (birhanu, 2013; leibenstein, 1975; world vision, 2022). moreover, women who belong to households experiencing food insecurity are at a high risk of experiencing negative sexual and reproductive health consequences, including ineffective utilization of contraception and unintended pregnancies. these outcomes are predominantly attributed to limited decisionmaking abilities and inadequate communication with their partners (ahinkorah et al., 2021). the socioeconomic status of women is also a significant factor in contributing to their participation in fundamental approaches to regulating fertility and promoting the effective utilization of progressive healthcare services (dixit et al., 2021). considerable differences in the number of children ever born exist according to women's age, income, marital status, food security status, contraceptive use, and childhood mortality. the effect of marital status on the number of children ever born was found to be significant at p < 0.05. this finding was in line with the findings of previous studies and reports (csa, 2016a; shiferaw et al., 2019), but opposed by a study conducted in the tigray region of ethiopia (atsbaha et al., 2016). single women are susceptible to precarious sexual and reproductive health outcomes, such as inadequate utilization of contraception and undesired pregnancy, primarily attributable to insufficient decision-making and inadequate communication with their spouses compared to married women (dixit et al., 2021). the age of the mother was also found to have a significant relationship with the expected number of children ever born at p < 0.05. this finding was consistent with a study conducted in ethiopia (abdu et al., 2018; adhikari, 2010; aragaw et al., 2023) but opposed the finding of a prior study (azmoude et al., 2017). the global sustainability research global scientific research 39 importance of these variables could be due to the fact that the likelihood of marrying and having more children increases as women get older, meaning that as women progress in age, there is a corresponding progression in their desire to achieve independence and establish an autonomous lifestyle. the cultural dimension also serves as a significant factor in the reinforcement of reproductive-age women to bear children before the cessation of their childbearing years (atsbaha et al., 2016). in the majority of instances, there is an inverse correlation between education level and fertility. the present study indicates that the absence of primary education among women is associated with increased fertility rates in comparison to those who have attained secondary and higher education (csa, 2016a, 2019). however, in this study, the level of education was not found to be statistically significant in predicting the effect of the number of children ever born. this finding was in line with prior studies (adhikari, 2010; azmoude et al., 2017) but in contrast with studies (aragaw et al., 2023; atsbaha et al., 2016; mekonnen & worku, 2011b; muche & gebremichael, 2020; rutaremwa et al., 2015). although educated women are usually more aware of family planning methods and the advantages and disadvantages of having children, they should have more autonomy and power in making reproductive decisions, so that they experience a lower fertility rate. this study has further revealed that employment status was not found to be a significant predictor in determining the effect of the number of children ever born. this finding corroborates studies (adhikari, 2010; azmoude et al., 2017; muche & gebremichael, 2020) but contradicts the findings of previous studies (andersen & özcan, 2021; muche & gebremichael, 2020). this fact might be elucidated by the observation that a significant proportion of women are employed in the informal sector, which is characterized by relatively low impacts on fertility. the finding of this study also confirms that there is a negative association between women's income and fertility, and this is in agreement with other studies (götmark & andersson, 2020; james et al., 2011; shiferaw et al., 2019), but opposes a study conducted in the east of iran (azmoude et al., 2017), which prioritizes the demand for children as the key predictor of the effect of the number of children ever born. the relationship between income and fertility rates was also reported to be direct by kolk (2022). the observed inconsistency may be attributed to the selection of subjects exclusively from urban areas, where educational resources are plentifully available even to individuals with low socioeconomic status. moreover, urbanization, commonly referred to as urbanism, is likely to be linked with a shift in ideas and attitudes concerning larger families. moreover, it is plausible that individuals living in urban areas possess enhanced means to procure contemporary contraception methods, consequently empowering them to efficiently implement their intentions to limit fertility rates (white et al., 2018). the difference in the number of children ever born between contraceptive users and non-users was also found to be significant at p < 0.05. other factors being equal, the difference in the rate of children ever born for contraceptive users is 0.641 times lower than for non-users. this finding was consistent with some studies (adhikari, 2010; aragaw et al., 2023; götmark & andersson, 2020; muche & gebremichael, 2020; shiferaw et al., 2019) but in contrast with (atsbaha et al., 2016; azmoude et al., 2017). the rationale behind the decline in fertility rates can be attributed to the crucial role played by contraception in promoting healthy timing and spacing of pregnancies. further, contraception has been proven to increase the likelihood of child survival through the spacing of births (megquier & belohlav, 2014). the findings of this study also reveal that the history of child mortality and the need for children were also found to be significant predictors of the effect of the number of children ever born. holding other factors constant, the number of children ever born is higher when women have a history related to child mortality. this finding corroborates studies (adhikari, 2010; atsbaha et al., 2016; jara et al., 2013; mekonnen & worku, 2011a; muche & gebremichael, 2020; shiferaw et al., 2019) but opposes the findings of studies (aragaw et al., global sustainability research global scientific research 40 2023; azmoude et al., 2017). the aforementioned phenomenon may be explicable by the fact that women who have experienced child mortality have the desire to replenish their children. nonetheless, they are apprehensive of a recurrence of the adverse outcome (atsbaha et al., 2016; endriyas et al., 2017). conclusions the current research demonstrates that the ability to access family planning services and effectively manage fertility is significantly hindered by food insecurity. moreover, within households experiencing food insecurity, women exhibited a decreased propensity towards utilizing contraceptive techniques in pursuit of attaining a suitable and satisfactory family size. the integration of suitable strategies aimed at enhancing the adoption of family planning services within food-insecure households is a crucial aspect of interventions geared toward regulating household fertility. therefore, stakeholders are anticipated to engage in collaborative and coordinated efforts across various sectors to address the challenges of food insecurity and fertility issues. such actions will prioritize expanding women's education, voluntary family planning initiatives, job creation programs, and initiatives to strengthen women's economic empowerment. finally, the study findings have been reinforced by the utilization of rigorous statistical analysis techniques and the attainment of high response rates in the data collection process. moreover, utilizing a thoroughly validated, structured questionnaire could have effectively mitigated the presence of instrumental and inter-rater biases. despite the extensive exploration of the interrelationship between household food insecurity and fertility, while adjusting for potential confounding variables, the cross-sectional design of the dataset restricts our ability to draw definitive cause-and-effect relationships between outcome and independent variables. continuous, longterm surveys and standardized measurement tools, such as the household food insecurity access scale, need to be employed in future studies to ascertain causal relationships among variables and discern the various levels of food insecurity. this is imperative to establishing a comprehensive understanding of the phenomenon under investigation. declaration acknowledgments: lideta sub-city of addis ababa is acknowledged for providing demographic data funding: no funding source to declare. competing interests: there is no

author: agroza ahmed ema. agroza05@gmail.com received: 28 may, 2023, accepted: 12 june, 2023, published: 05 july, 2023 abstract offshore buildings are used in various locations and sea depths for several reasons. different equipment, platforms, and design techniques are needed depending on water depth, climatic conditions, structural arrangement, and new concepts. offshore constructions usually generate and transport oil, gas, and other commodities. bangladesh has yet to use the bay of bengal's hydrocarbon potential for oil and gas. bangladesh lags behind india and myanmar in maritime oil and gas discovery. in 50 years, bangladesh's sea barriers have yielded no benefits. bangladesh's economy is hindered by its high crude oil imports. focus on offshore petroleum exploration to locate "black gold" now. therefore, an offshore structure is needed. this thesis paper covers the fundamentals of all offshore systems, broadens the research, and recommends appropriate platforms for various sea-water depths, which those platforms are meant to be built for hydrates predicted in the bay of bengal. the paper uses the bay of bengal sedimentation and estimated water depth to choose offshore constructions. the country's maritime boundaries have 26 oil and gas blocks. there are 11 in shallow water and 15 in deep sea. according to statistics, the blocks are on the continental shelf and deep-water region. five zones make up the bay of bengal continental shelf. they are shores a-b, b-c, c-d, d-e, and e-f after region f continental slope continues till the deep sea area. the continental slope zone c-d has 64-106 m water depth. therefore, the bay of bengal continental shelf is suitable for all permanent offshore buildings except this zone. only concrete gravity platforms fit this zone. we need the technology to search for oil and gas in water. it takes a lot of work to get foreign companies to work together. thus, skilled people should work on it and encourage government or private businesses to develop oil and gas production technology. keywords: offshore structures; hydrocarbon; bay of bengal; continental shelf; sediment introduction offshore describes a location on water that is far from land. however, offshore construction entails erecting buildings and other infrastructure out at sea. offshore structures are typically constructed and precommissioned on the ground. offshore structures exposed to waves, seismic activity, wind, or a mix of these stressors exhibit non-linear, abrupt behavior. the ocean floor's topography is analyzed for petroleum reserves after seismic studies have been conducted. when the probability of finding hydrocarbons is high, the surveyor is prompted to dig deeper, and the quantity of hydrocarbon potential yields figures for the most costeffective offshore building in the area. oil and gas are being explored all over the planet. onshore exploration refers to work done on land, while offshore research occurs in water. there is also a third zone, but it has a minor trade effect. transition zone exploration is another name for this, though shallow water exploration is more common. this includes areas with shallow water, such as coastal areas, waterway channels, and swamps. exploration methods in such regions are often complex. offshore building projects have their own technical and monetary quirks. offshore building projects rely heavily on the profits made from oil and gas extraction, which are directly linked to international finance and indirectly affected by oil price fluctuations. for instance, numerous mailto:agroza05@gmail.com global sustainability research global scientific research 22 offshore construction projects were initiated in 2008 as a direct consequence of the increase in global energy costs that year (atreya et al., 2013) soon after bangladesh became an independent country in 1971, oil was taken out of the ground for the third time (1971–1990). six multinational companies, including arco, ashland, and union oil co., sank seven wells in the bay of bengal between 1974 and 1978 to investigate distant areas under production sharing contracts with petrobangla (the state oil company). thus, the distant kutubdia gasfield was discovered. one thousand nine hundred eighty all foreign energy companies had left bangladesh, leaving only petrobangla. a petroleum reservoir's porosity and permeability are crucial physical qualities when storing and transporting fluids. both characteristics are essential when defining a reserve. particle size and form, pore size, grain sorting, cementation, compression, packing fracture, and solution are significant in determining reservoir-scale porosity and permeability. however, aside from the work of a few undisclosed oil and gas companies in the bengal basin, no efforts have been made to quantitatively quantify core and log petrophysical characteristics and their potential governing variables (ismail & shamsuddin, 1991). bangladesh has relatively small hydrocarbon and lignite deposits, but its natural gas supplies could be huge. most natural gas and petroleum oil come from sylhet division in the country's northeast, followed by chittagong division, dhaka division, and barisal division. most people think that bangladeshi natural gas is one of the cleanest in the world because it has a high methane content (95–99%) and almost no nitrogen content. of the total 25,602 km2 that was in question, bangladesh got 19,467 square kilometers (km) of territory in the sea from the hague's arbitral tribunal, which presided over the maritime border dispute between bangladesh and india in the bay of bengal. therefore, the marine sector in bangladesh holds excellent promise. the bay of bengal is home to numerous oceanic islands that may be highly mineral-rich. furthermore, unb reports that bangladesh has discovered massive potential natural gas hydrate deposits in its exclusive zone, with estimates ranging from 0.11 to 0.73 tcf. it is equivalent to 17– 103 trillion cubic feet (tcf) of natural gas (shahjahan et al., 2002). bangladesh is rich in natural resources and spans an area of 147,610 square kilometers, stretching from north to south for 820 kilometers and from east to west for 600 kilometers. regarding geography, the bengal basin can be found in an area characterized by exceptionally high levels of geological activity. a great number of dynamic geological features can be found within and all around the bengal basin. the region of the indian ocean, located to the northeast, is defined by the estuary of bengal, the largest estuary in the globe. it is a triangular shape and is bordered on three sides by other countries: to the north by bangladesh, to the east by myanmar and the andaman and nicobar islands, and to the west by india and sri lanka. the bay of bengal encompasses a total area of 2,172,000 km2 of land and water. to use a metaphor, the country of bangladesh sits at the very tip of the bay of bengal. the length of the nation's exclusive economic zone is 370 kilometers (200 nautical miles), while the size of its territorial waterways is 12 nautical miles (22 kilometers). the land is reportedly subdivided into 26 separate sections, as stated by petrobangla. the psc district plan is presented in the following image. there are 11 sections from the coastal sea and 15 blocks from the deep sea. on the chart, far offshore is represented by a dark blue color, while shallow offshore is shown by a lighter blue color (shahjahan et al., 2002). since the industrial revolution, energy demand has grown while supply has not. bangladesh's power sector relies largely on fossil fuels since natural gas and coal are its main energy sources. diesel, coal, heavy oil, and biofuels comprise the rest of bangladesh's power generation. bangladesh's energy field includes power, fuel products, natural gas, coal, biogas, and sun. exploiting its abundant green energy sources may solve bangladesh's power issue. the problem should be addressed by massively using ocean waves and the bay of bengal. offshore buildings and energy use are the most effective way to use bay of bengal resources. the following research and investigation objectives were set in light of the preceding discussion: • explore about offshore structures in detail in preparation for their use in the near future; • examining the potentiality of bay of bengal blocks for offshore constructions; • prediction of primary selection of offshore structures for those hydrocarbon potential area. global sustainability research global scientific research 23 literature review detailed study on offshore structures maritime and offshore structures must withstand harsh sea conditions for their plan spans. (50 to 75 years for ports and 25 years or more for offshore hydrocarbon platforms). peak loads from storm gusts and waves wear loads from waves over the platform's lifespan and platform motion are essential to design aspects. offshore buildings are built miles from shorelines in lakes, gulfs, and the open sea. these structures are made of mild to high-strength steel. the world's tallest artificial buildings are offshore towers. this chapter covers offshore building history, kinds, and loads that must be computed for design, plans and specs, production, installation, and environmental considerations (ismail & shamsuddin, 1991). figure 1. three key criteria for offshore station design (bhattacharya et al., 2006). a fixed offshore station design must meet three key criteria endure all expected loads during production, shipment, and installation withstand storm and earthquake loads drilling, production, & housing facility global sustainability research global scientific research 24 from 1909 to 1910, louisiana dug wells. timber derricks were raised on hastily built timber supports on woodpiles. two main types of fixed platforms have evolved in the past 40 years: the concrete gravity type, built in the north sea, and the steel template type, built in the gulf of mexico (gom). due to the need to dig deep water wells and build deepwater gas projects, the tension-leg platform was introduced as a third type. in 1976, exxon built a 259-meter-deep platform in santa barbara. (850 ft.). the most widely used form of energy and liquid fuels is crude oil, and its use is likely to persist for decades (dawood et al., 2013). figure 2. offshore structures.

(100 feet). in the 1960s, gom hurricanes damaged the station, forcing a redesign. hurricane hilda in 1964 destroyed 13 platforms with 13meter waves and 89-meter-per-second winds. the following year, typhoon betsy, a 100-year storm, injured several stations and destroyed three. designers began planning for 100-year storm repeat periods instead of 25 and 50 years. figure 3. types of offshore

east, southeast, and south corridors yielded natural gas. sangu is bangladesh's only offshore gas field. sylhet's haripur contains natural oil, but the region's only oil well produces too little. bangladesh is behind other nations in oil and gas research because the energy sector has yet to help the economy as much as expected. bangladesh's oil and gas assets are hard to estimate due to a lack of exploration data and ocean digging. this paper summarises the bay of bengal and bangladesh marine petroleum scenario. the bengal basin provides gas and a few liquid fuels (mainly condensates and light oil). in the bengal basin, oligo-miocene sediments are source rocks, and miocene-pliocene sediments are storage rocks. most studies of the bengal basin's parent rocks have focused on middle miocene strata dug from depths greater than 4 kilometers (ismail et al., 2014). the surma group unconformably overlies the paleogene turbidites, and the submerged fan complex appears to have persisted into the upper deep water. deep-marine facies connections of abundant petroleum deposits have gotten the least attention (dasgupta, 2004). figure 5. hatia depression and the ocean area are depicted on a contour depth map, the mid-miocene strata that lie within it serving as a petroleum reserve (dasgupta, 2004). global sustainability research global scientific research 28 the bhuban formation formed the offshore bengal basin hatia petroleum system. beyond the surma basin to the south and southeast, oil and condensate are isotopically denser (-24.5 to -26.6%) with negative canonical features, indicating marine or marineinfluenced source rocks from type-ii or type-ii/iii kerogen. the oil output window is between 5400 m and 10000 m because sands with low vitrinite absorption bury quickly. methane carbon isotope rates indicate that miocene and pliocene pools contained old parent rock (roybarman, 1987). a study of the source rock potential of chosen cores from the muladi-1 well in bangladesh found that extractable organic material linked to carbon content rises with depth in shale samples, suggesting age and source oil. oil leaks at hararganj, sitakund, utan chatra, and the patharia indicate that mature source rocks produced liquid petroleum during the oil production window. except for the lower miocene gasprone source rocks, the horizons of the oligocene, upper eocene, and paleocene show fair to excellent oil source potential, with an oil window maturity zone between 5000 m and 8000 m in the deeper basin. geochemical and source rock palynological data from west bengal, india, suggests that the mature source rocks of the paleogene-early neogene series may be located at the eocene slope break (hasan & qasim, 2017). wet gas is more common in cores from the mnd-2 well in the offshore mahanadi basin below 3300 meters, while mature source rocks for oil are at 2500 meters (basal miocene). due to its continuous fracturing and delta build-up, the jenum formation of the oligocene barail group, the main source rock in assam and the surma basin is widely regarded as the offshore bengal basin source rock. geologists believe bengal basin deposits are source rock and top rock. these sands aided hydrocarbon capture. the ocean area has folded and inverted crustal segments. find extremely high buildings (saiful et al., 2011). younger bending and reversal between paleode and neode formation fronts are usually minor and straightforward. inversion zones may acquire tiny, hidden bends. controlled faulting and structural closures are likely. hydrocarbon migrates vertically through cracks and laterally up-dip over pale slopes, making the offshore bengal basin ideal for hydrocarbon capture at 4-6 km. channels filled with mud and sand, channel sands, incised valleys where heavy channeling happened, and pro-delta clays that move up-dip to delta-front sand wedges are ideal petroleum traps (greaves et al., 2017). table 1. offshore

south and southeast, oil and condensate are isotopically denser (-24.5 to -26.6%) with negative canonical features, indicating marine or marineinfluenced source rocks made from type-ii or type-ii/iii kerogen. since layers with low vitrinite absorption bury quickly, the oil output window is expanded between 5400 m and 10000 m (shahjahan et al., 2002). the parent rock in miocene and pliocene pools was old based on methane carbon isotope ratios. according to a study of the source rock potential of chosen cores from bangladesh's muladi-1 well, extractable organic material linked to carbon content rises with depth in shale samples, suggesting age and source oil [9]. the patharia well's oil show and leaks at hararganj, sitakund, and utan chatra suggest that mature source rocks produced liquid petroleum during the oil production window. except for the lower miocene gas-prone source rocks, the horizons of the oligocene, upper eocene, and paleocene show fair to excellent oil source potential, with an oil window maturity zone between 5000 m and 8000 m in the deeper basin. geochemical and source rock palynological data from west bengal, india, suggests that the mature source rocks of the paleogeneearly neogene series may be located on the eocene slope break ( imam & hussain, 2002). according to studies of cores retrieved from the mnd-2 well in the offshore mahanadi basin, wet gas is more common in samples below 3300 meters, while mature source rocks for oil are at 2500 meters (basal miocene). the jenum formation of the oligocene barail group, the primary source rock in assam and the surma basin is widely regarded as the source rock in the offshore bengal basin due to its continuous fracturing and delta build-up. according to geologists, the bengal basin may contain source rock and cap rock deposits. these layers may have helped trap hydrocarbons. in the distant area, crustal segments show unique bending and inversion patterns. high-rise buildings may be found. younger bending and reversal between the paleode formation and neode formation fronts is simple and tiny (islam, 2010). inversion zones can produce tiny, hidden bends. structural openings with managed faulting are likely. the offshore bengal basin has favourable hydrocarbon capture at depths of 4-6 km because hydrocarbon migrates vertically via cracks and laterally up-dip over paleoslopes. channels, channel sands, cut valleys, and pro-delta clays that move up-dip to delta-front sand wedges are ideal geological traps for hydrocarbons (lafond, 1957). methodology this is an observational study that required a lot of time spent behind a computer and in a library. review study focused on whether or not floating structures in the bay of bengal would be safe to inhabit. literatures pertinent to marine buildings that need to be reviewed include printed materials (books, journals, and periodicals), internet journal articles, and symposium papers. (google scholar, web of knowledge). results and discussions the term "petroleum resources" refers to the estimated quantities of hydrocarbons on and below the planet's surface. the potential for a resource to be recovered and sold is estimated in both resource assessments and resource evaluations, while the latter focuses mainly on the latter. bangladesh's considerable hydrocarbon potential has been the subject of several resource evaluations and publications, either independently by different government agencies or in partnership with petrobangla. bangladesh is a good location for numerous active petroleum systems since its potential source rocks span from the cretaceous to the miocene, which is old enough to enable hydrocarbon accumulation in any competent conventional trap. this article shows the accessible resources and a good platform for extracting hydrocarbons. however, there needs to be more knowledge to make educated judgments now. both coastal and deep sea areas are included in the 26 oceanic regions. building choices can only be made with a degree of certainty once we have a better understanding of the sedimentary composition of the area. the offshore basin was sedimented twice: first in the triassic, when the sibumasu terrane moved from gondwanaland and produced the west burma block, and again in the early tertiary, when india collided with eurasia, constructing the himalaya (dyanati & huangq, 2014). the continental shelf at the head of the bay of bengal is as much as 100 miles wide but narrows to the south. the features of the continental shelf in this region are as follows: • a width of approximately 25 miles. • an average slope of 0 degrees and 15 minutes. global sustainability research global scientific research 30 • a depth at the outer edge of around 100 fathoms. a unique feature is that the shelf can be divided into five zones. each has its own set of slopes and sediments. a sixth zone comprises the upper part of the continental slope. each zone runs nearly parallel with the shore. the average widths, slopes, and depths of those zones are given below: table 2. continental shelf zone zone width(mi) slope (degrees) depth(fms) depth of zone shore a-b 2 0 degree 26 minute 0-15 0m to 27m b-c 11 0 degree 4 minute 15-35 27m to 64m c-d 6 0 degree 11 minute 35-58 64m to 106m d-e 2 0 degree 35 minute 58-70 106m to 128m e-f 2 1 degree 9 minute 70-112 128m to 205m there is a lot of globigerina ooze in the sediments of the deep bay of bengal basin, which is one of the things that sets them apart. the continental slope yields dark gray samples with a bluish tint and a pliable, soft texture. several blocks in the ds series are located in an area with deep water: ds-12, ds-16, ds-21, ds-19, ds-20, and ds-22. hydrocarbon source rocks are characterized by a high maturity level within the oil generation window for deeper sediments, consistent with a marine environment of deposition. sites in deep water are typically situated in regions with thick sediment deposits on the continental slopes that slope gently into the abyssal plains. in these regions, the average slope of the seafloor is relatively shallow (less than 4 degrees). using buoy-measured data from february 2013 to december 2015 off gopalpur at a depth of 15 meters, this article describes the spectral wave characteristics of the nearshore waters of the northwest bay of bengal. the southwest monsoon is associated with increased wave heights and more extended wave periods, as indicated by the seasonal mean significant wave height and mean wave period. a year's worth of waves between 138 degrees and 228 degrees accounts for 74% of the variation in sea level, with those between 48 degrees and 138 degrees accounting for 16%. the monthly average wave parameters show substantial interannual variability due to the occurrence of tropical cyclones. on october 12, 2013, a significant peak wave height of 6.7 meters was recorded due to the effects of tropical storm phailin. on october 12, 2014, a significant peak wave height of 5.84 meters was recorded due to the effects of tropical storm hudhud, whose track was 250 kilometers southwest of the study location. the analysis showed that a single tropical cyclone affected the annual maximum significant wave height, while the annual average value was nearly identical (1 m) in both 2014 and 2015. western bay of bengal waves are affected by cyclones, swells from the southern ocean, and the southwest and northeast monsoons (maurin & rangin, 2009). table 3. platforms according to water depth platforms required water depth concrete gravity platform within 200 m and best from 100 m to 150 m, can be suited up to 350 m steel template structure up to 500 m complaint structures normally 300 m to 600 m larger tlp successfully has reached 1250 m spar platform presently used up to 1000 m though technology can extend up to 2500 m (deep water platform) fpso up to 2600 m semisubmersible 1800 m conclusion hydration study has resurfaced among experts worldwide due to several reasons. it could become the next generation's pure energy norm. hydrates are abundant worldwide. the upstream offshore oil and gas value chain includes drilling rigs, research and support ships, platform building, production, and extraction. downstream work includes refining and selling goods. our energy supply, primarily natural gas and a potential new oil sector at sea, rests mainly on fossil fuels, which can be dug and handled. bangladesh still needs to assess its marine petroleum potential. bangladesh has 26 tcf of gas, but only 1 tcf is offshore. up to 2014, 19 exploratory wells were dug in the bay of bengal, but only two gas finds—the sangu and the kutubdia—had minimal amounts. sangu's 0.8 global sustainability research global scientific research 31 tcf stocks are gone, but kutubdia's 0.04 tcf are not. the magnama (3.5 tcf) and hatia (1.0 tcf) have been dug but have not yielded marketable petroleum. bangladeshi areas near myanmar's gas deposits may have similar natural traits and gas or oil prospects. thus, subsea structures for harvesting deposits and developing current structures are essential. water depth and deck tools determine which level is best. fixed platforms of steel template and concrete gravity fit blocks ss-01, ss-02, ss-03, ss-04, ss-05, ss-06, ss07, ss-08, and ss-11, which have ocean depths up to 200 m and layers without rock zones. since ss-09 and ss-10 are in a rock zone, concrete gravity is best. the deep-sea rocks' geological knowledge is limited to their 2000–2500 m ocean level. we cannot specify a platform for those pieces. we can only recommend deep-water platforms like bigger tlps, spar, fpsos, and semi-submersible platforms. a well-planned approach for finding oil and gas areas and deposits is needed to perform a multi-line scan in the bay using cutting-edge technology. whoever drills last is likely to pull not only their fair share of gas and hydrocarbon reserves but also those from across the boundary, so any delay in exploration could negate the opportunity to harness hydrocarbon resources, especially those (if any) located on either side of the maritime boundary (india and myanmar). extensive digging and research are needed to increase gas output. petroleum extraction will require public-private cooperation to share data, information, tracking, best practices, assessment methods, and results. in order to predict resources for future use, the government should build a hydrate-stable map of the nation in the bay of bengal area. • little research was conducted on the distant regions, so scarce information was available. • since underwater building is so novel, there are few tools to draw from. • the marine islands of bangladesh have never been surveyed. this means that no information regarding the area's bathymetric shape exists. • tides, currents, ocean temperature, and other aspects of that marine region were poorly understood. acknowledgment: none funding: no funding received conflict of interest: the authors shows no conflict of interest data availability: n/a references atreya, p., islam,

(2008) highlighted that nearly 10% of the global burden of disease was attributable to unsafe water, lack of sanitation, and poor hygiene, claiming 3.6 million lives annually. recent data from the world health organization (who) indicates that unsafe water, sanitation, and hygiene (wash) continue to pose significant health risks. in 2022, contaminated water sources caused approximately 505,000 diarrhoeal deaths annually, with microbial contamination being the primary concern. despite progress towards sustainable development goal 6, which aims for universal access to safely managed water and sanitation by 2030, around 2.2 billion people still lacked access to safely managed drinking water in 2022. this lack of access exacerbates health risks and hinders economic and social development (who, 2023). addressing the global water crisis requires concerted efforts to improve water access and sustainability, particularly as the global population grows. enhancing wash infrastructure and management is essential to reduce preventable diseases and support overall community wellbeing (who, 2023). the concept of sustainable development has gained increasing attention and relevance in the last decades. the term sustainable development is defined as ‘development that meets the needs of the present without compromising the ability of future generations to meet their own needs’ (wced 1987, p. 43). in practice, sustainable development is a societal concept that is grounded in three basic principles; environmental integrity, economic prosperity, and social equity which is commonly referred to as the three pillars of sustainability (elliott, 2005). therefore, access to potable water should be sustainable based on these three principles. according to annor (2011), if care is not taken, the next world war would occur as a result of water crisis. though there is an increase in population, the world through the sustainable development goal (sdg) 6 has committed itself to attaining universal water coverage by 2030 by improving upon the 75% universal coverage of water proposed in the millennium development goal 7 which just ended in 2015. the sustainable development goal (sdg) 6 seeks to ensure availability and sustainable management of water and sanitation for all. it focuses on achieving universal and equitable access to safe and affordable drinking water. about 71 percent of the global population (5.2 billion people) used a safely managed drinking water service; that is, an improved drinking water source located on premises, available when needed and free from contamination while over 844 million people still lacked even a basic drinking water service (drinking water from an improved source, provided collection time is not more than 30 minutes for a round trip) (global health observatory (gho), 2015). in ghana, though there seem to be increasing water coverage nationwide, the situation on ground lives much to be desired since majority of the people living in both urban and rural areas have limited access to water. more than 40 percent (10 million) of ghana's 25 million people do not have access to safe water (safeghana, 2018). report by the parliamentary select committee on works and housing in ghana (2017) revealed that 24% of urban dwellers have no access to potable water. similarly, a critical analysis of data collected in 2014 by the sekyere kumawu assembly on water and sanitation facilities in the district visavis the population revealed that access to potable water is woefully inadequate (dpcu-skda, 2014). these people are therefore left with no other choice than to find their own means of getting water. however, due to poor management and sustainable practices, most of the water point sources are not reliable and potable. historically, households in sekyere kumawu district have experienced water crises since the broke down of treatment plant installed at river onwam in 1995 due to lack of maintenance (gwcl, 2013). the affected population have been relying on other water point sources such as streams, springs, rainwater, tankers, water supplied vendors, ponds, rivers, boreholes, wells as well as sachet water (ghana statistical service and population and housing census, 2010). recently, sekyere kumawu district was provided with reservoirs of pipe borne water as part of the benefits of the konongo, kumawu and kwahu water expansion project (“3k project) of the ghana water company limited. under this project, public tap/ standpipes were provided to serve as a service point (service centre) and access point sources to the pipe-borne water from the reservouir. these access point sources served as places where pipe global sustainability research global scientific research 61 taps are mounted for households to fetch water to their various homes. however, the number of public standpipes provided under the “3k project” is not enough to meet the needs of the affected communities in the skd. also, some of these public tap/ standpipes are located at the foot of some highlands (hills) and others are at a far distance from the places of residence of the households which makes it difficult to access this water. additionally, the prices as which water is sold to the people also makes affordability a problem. the inability of the people, especially, those in the rural communities, to afford the cost make the water supply inaccessible though it is available. on the other hand, there are a lot of incidence of burst pipes almost every day, dalliance in connection of pipe to various homes, as well as inconsistent in water flow of taps. despite the fact that the konongo, kumawu and kwahu water expansion (3k) project has made potable water available to the sekyere kumawu district, there are threats to its equity distribution, sustainability, accessibility, and affordability. nevertheless, there is paucity of empirical evidence on difficulties that household face in accessing potable water and how these water point sources are managed and sustained among others. this study, therefore, sought to examine the access to and sustainability of potable water sources in the sekyere kumawu district. literature review potable water grandjean (2004) define potable water as water that is considered safe for drinking and can be used for other domestic purposes. it is either treated, cleaned or filtered and meets the locally established drinking water standards (free of harmful bacteria and contaminants). examples of potable water would be tap water from treated municipal water systems, or that has been ultraviolet filtered, water distilled, or purified by reverse osmosis. water point sources there are a lot of repositories of water which many households draw their potable water from for both domestic and industrial purposes. these sources are not limited to, but include; springs, wells, boreholes, pipe stands, water tankers/vendor supplies among others. groundwater is less susceptible to pollution due to its location within the earth crust (water table/aquifer) and for that matter, it is often recommended for use as drinking water (kortarsi, 1994). groundwater can be tapped to the earth surface through either by wells or boreholes, spring and infiltration galleries (kpordze, 2010). wells and springs are rampantly used by developing countries as a source of drinking water. springs occur naturally whereas wells are dug, drilled or bored. a well is an issue of water from the earth: a pool fed by a spring (marriam webster, 2015). it is also known to be a pit or hole sunk into the earth to reach a supply of water. tilton (n.d.) also defines a well as a hole or shaft drilled down through the earth to water-bearing stratum of sand, gravel, or a crack in the rock. there are different types of a well according to their mode of construction. for instance, hand dug wells are the most common method of abstracting groundwater in developing countries. hand dug wells have relatively large diameters (often ranges from 1–2m) to allow sufficient digging space. on the other hand, depths may range from shallow wells (3-5m) to deep wells 10 to over 20 m to ensure that water table can still be reached in dry seasons (kpordze, 2010). a traditional hand dug well is often drawn using rope and bucket and this makes it prone to contamination since they are often not covered and the rope or bucket could be contaminated before placing it into the well (powell black & hickman, 1992). another mode of construction could be in the form of drilling to deeper depths using drilling rig or augurs. boreholes are deeper (depth 20-100m and over) than tube wells. the boreholes are also drawn using hand pumps or mechanical pumps. research has shown that though the initial costs of boreholes are expensive, they are less susceptible to contaminations since their diameters are relatively smaller and they are also sealed with the hand pumps or mechanical pumps (wateraid, n.d.). water tankers are the vehicular reservoir used to fetch water from rivers or pipe stands and then distribute to the requested households at a fee or cost. moreover, water supplied vendors include individuals who used to fetch water from other water point sources such as springs, rivers, streams, wells and or pipe stands and sell it to households for money. these people normally put the water in plastic global sustainability research global scientific research 62 containers, “gallon” and small poly tanks as well as buckets. furthermore, stand pipes are places where pipe taps are mounted for households to fetch water to their various homes. this type of water is treated by the ghana water company limited at a fee or cost. functionality of water point sources the functioning and non-functioning of water point sources are termed as functionality. studies conducted on the functionality of water point sources by care (2012) and habtamu (2012) place functionality under the type of technology (a type of hand pumps) employed, the availability of spare parts in the local market and availability of skilled personnel for operation, repairs and maintenance. factors that contribute to long-term functionality of technologies included; governance, diversity and inclusivity of committee members such as, female involvement and training for maintenance and repairs. care (2012) further indicates that the involvement of women in committees contributed tremendously to water point functionality in northern mozambique. on the other hand, insufficient training for operation and maintenance and lack of spare parts in the local market were the factors dwindling the functionality as well as sustainability of water point sources. most of the spare parts are imported and are not locally manufactured and hence the reason for is unavailability in the market. habtamu (2012) again, indicates that the community participation in the choice of technology was another contributing factor enhancing long-term functionality since the people felt a sense of ownership and protection of the propriety. also, the community involvement in the construction of the technology coupled with the training received, equip them with some skill on repair and maintenance (hayson, 2006). mapping of water points according to welle (2007), mapping is the act of bringing what is hidden in the dark to light. mapping can be in any form based on what information is required. in order to envisage information of a particular jurisdiction, a map is created at the end of any mapping exercise. mapping according to welle (2007), serves as an advocacy tool since it provides citizens as well as a local government with information and arguments to demand improved services. mapping of water point sources helps in revealing information such as coverage (number of water point sources in the system), access levels (number of population which has access to water), functionality (number of water point functioning and non-functioning), water quality and equity (fair distribution of water points) of service delivery (wateraid, n.d.). information gathered from mapping is very useful for improving planning and monitoring of water service delivery nationally and locally by local government and water service providers (welle, 2007). welle (2007) further argues that mapping in itself is a tool that is used by water service providers and agencies such as wateraid (water and sanitation body) to track its projects. in as much as mapping can be advantageous, it can be misleading since changes cannot be provided on maps generated as and when they occur (welle, 2007). for instance, after mapping a particular place, any activities like demolition that goes on cannot be factored again into the map. again, mapping is done based on the information the mapper is looking for and so several maps are generated for various purposes. welle (2007) argue that data gathered had to be entered into a compatible mapping tool that may require training, skill and experience. access to water point sources access to safe drinking water is a fundamental precondition for the enjoyment of several human rights, including the right to education, housing, health, life, work and protection against cruel, inhuman or degrading treatment or punishment. it is to eradicate discrimination among sex, income status and social class (un-water, 2009). access to water can be defined based on parameters such as population, distance, time and quantity (moriarty, batchelor, fonseca, klutse, naafs, nyarko, pezon, potter, reddy & snehalatha, 2011). with regard to population access to safe drinking water is defined or estimated by the percentage of the population using improved drinking water sources such as protected hand dug wells, boreholes, protected springs, public standpipes and rainwater harvesting (joint monitoring program, 2011). a household is considered to have access to an improved water source if it gets drinking water primarily from a pipe-borne water supply system, a public standpipe, borehole and dug well global sustainability research global scientific research 63 with pump, a protected spring, a well-developed rainwater harvesting system, a reliable water vendor or water tank truck. sources such as direct from surface waters, thus, rivers, lakes, ponds, etc. and unprotected wells and springs are regarded as unimproved water sources (united nations international children education fund (unicef), 2008; world health organization (who), 2008). according to who (2011) and community water and sanitation agency (cwsa) (2007), a water point source such as borehole must serve 200 to 300 persons. studies conducted in ghana shows that most often than not a water point source (borehole) serves less than 300 people at a time (moriarty et al., 2011). access to a water point source in terms distance must be between 200m to 500m (moriarty et al., 2011). according to joint monitoring programme of who (2000), reasonable access to a water point source in terms of quantity must be available to a person at least 20 litres (five gallons) per day from a source within one kilometre of the user’s dwelling. however, in ghana, cwsa defines access to safe drinking water in rural areas to include supplies from boreholes delivering a minimum of 20 litres per person/day, serving at least 300 persons each within 500 meters of households being served (cwsa, 2007). with regards to time, it is recommended by un to be 30mins per a normal trip (from house to water and back to the house). as the amount of water accessed every day is largely determined by the distance to the water source and the collection time, a reasonable distance is one that allows everyone to collect sufficient water to cover personal domestic uses. according to who, in order to have a basic access to 20 liters per day, the water source has to be within 1,000 metres of the home and collection time should not exceed 30 minutes. when water is piped into the home, access is optimal and at least 100 litres per person per day is likely to be ensured. in this respect, united nations development programme (undp) confirms in its human development report 2006 that having a regular supply of clean water piped to the household is the optimal type of provision for human development. access to a regular supply of water within the home also eliminates the need for women and children to spend time and physically exert themselves to collect water from distant sources. howard and bartram (2003) defined access to potable water using four levels based on four board service levels which are distinguished on three categories namely; distance the consumer travels or the time spent collecting water, the quantity of water collected and the health concerns of water consumers. to them, basic access to water offers minimum health protection, and users of this service level will have access to less than 20 litres of water per day which includes 7.5 litres required for consumption. on the other hand, optimal access to water offers a minimum of 100 litres per day which is normally seen in houses with multiple pipe stands. here, the level of health concern is very low and quality is readily assured. access to water in urban areas in ghana has increased over the years since people in urban areas depend mainly on piped-borne water supplied by gwcl. the ghana statistical service (gss) (2014) indicates that about 95 percent of urban households have access to potable water (pipe, borehole and bottled water). though access to water has increased, people usually have to travel outside their homes to collect water. this may be due to the landscape of the area, planning or settlement pattern and one’s income status. sustainability of water point sources the term ‘sustainability’ is derived from the latin sustenere meaning to maintain and its use in relation to the resources of the planet has a long pedigree dating from the late 18th century. the contemporary term sustainable development was popularised in 1987 in the brundtland report which defined sustainable development as “…development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs” (world commission on environment and development (wced), 1987:43). subsequent work on sustainability stems from action under the 1992 united nations (un) conference on environment and development, specifically agenda 21. ‘sustainability and sustainable development’ have been defined in several ways by different institutions and researchers (awoke, 2012). dfid (2000) suggests that sustainability has been achieved when prevailing structures and processes have the capacity to continue their functions over the long term. bjornlund (2004) defines sustainability as the satisfactory functioning and effective use of services, and equity as when everyone (men and women, rich and poor) … have equal access to benefits from projects. for the purpose of this study, sustainability is defined as the continuous provision of acceptable services in an equitable manner to beneficiaries for a targeted lifetime without any form of discrimination. global sustainability research global scientific research 64 sustainability can be defined as the functionality of water point sources over a long period of time (habtamu, 2012). since the world committed itself to provide water to halve the world population without access to safe drinking water by the year 2015, the focus has been provisioning rather than sustainability. every year, large sums of money are used in the implementation of water supply projects but only a few are seen functioning at the end of the year or two (gebrehivot, 2006). thus, these huge sums of money invested often go to waste. it is estimated that 35% of all rural water supplies in sub-saharan africa are not functioning and despite the frequency with which it appears in development discourse, the reality of sustainability remains elusive (habtamu, 2012). moreover, research has also shown that rural water supplies (often water point sources) in sub-saharan africa, particularly those relying on hand pumps, often demonstrate low levels of sustainability. the key causes for this include inappropriate policy or legislation; insufficient institutional support; unsustainable financing mechanisms; ineffective management systems; and lack of technical backstopping. the problem will only be solved by adopting a holistic approach to planning and implementation rather than focusing on one issue (habtamu, 2012). no wonder sustainability lately has become a prerequisite for inclusion in a project proposal document and in the objective of every water supply and sanitation projects (parry-jones, reed & skinner, 2001). methodology study area the sekyere kumawu district is located between latitudes 0° 20’ and 1° 20’ north and longitudes 0° 45’ and 1° 15’ west. it covers an estimated land area of 576.58 square kilometres, which forms 6.2 percent of the total land size of the ashanti region (skda, 2014). figure 1 depicts that the district shares common boundaries with the sekyere central district to the west, sekyere east and asante akim north districts to the south and the sekyere afram plains district to the east. kumawu, the capital of skda is about 54 kilometres north-east of kumasi, the regional capital. the population size of the district is 65,402 with females recording 34,421 (53.4%) and males 30,981 (46.6%) (gss, 2010). the district is predominantly rural with a rural population of 34,530 (52.8%) as compared with the urban population of 30,872 (47.2%). it has a growth rate of 3.5 percent (gss, 2010). there are 14,185 households in the district. the sources of drinking water for households are rivers/streams (30.2%), followed by bore-hole/pump/tube well (29.3%) (gss, 2010). one out of every five households obtain drinking water through tanker supply/vendor provided, which account for 15.7 percent of all drinking water available to the district. pipe-borne water (public tap/standpipe, outside and inside dwelling) is the source of drinking water for 11.3 percent and 7.6 percent of rural and urban households, respectively (gss, 2014). figure 1: a study area of sekyere kumawu district global sustainability research global scientific research 65 the study adopted a mixed approach (a combination of qualitative and quantitative methods). according to johnson and onwuegbuzie (2004) and creswell (2012), merging the quantitative and qualitative techniques of data analysis concurrently helps to balance the strengths and weaknesses of the two, while it aids in achieving a greater degree of validity and reliability. the study used a multi-stage sampling to select 390 respondents within the sekyere kumawu district based on the household population (16,292) with the aid of yamane (1967) formula for determining sample size. the residential areas involved in the survey were stratified into fourkumawu, bodomase, besoro and woraso and households. the stratification was based on the communities who were without potable water and now being served with pipestand as well as the income status of the area. a purposive sampling technique was employed in gathering data from 9 key stakeholders. these key stakeholders included; an assembly member, the chief, 3 water vendors, and the manager of ghana water company. primary data were sourced using structured questionnaires, interview guide, gps and field observational checklist. the study adhered to highly ethical issues such as informed and free consent, anonymity, and confidentiality of the respondents. the statistical product and service solutions (spss version 25) was used to process and analyse the data. also, interviews were manually transcribed, coded, grouped into themes and discussed whereas pictures taken during observations were presented to support the findings of the study. results and discussions demographic characteristics the study was predominantly female (59.5%) with about 44 percent of respondents aged 58 and above, primarily subsistence farmers, with 24.9% of the respondents being well-informed about water accessibility and management. most respondents were christians (85.4%), followed by muslims (11.5%), mirroring the district's religious demographics. educationally, a notable number of respondents lacked formal education, necessitating interviews for data collection. marital status showed a majority (77.2%) were married, aligning with the demographic trends of the district. household sizes varied, with 46.2% having between 1 to 5 members, slightly higher than the district average. the majority of respondents had lived in their communities for over 20 years, indicating deep familiarity with local water issues. occupation-wise, 40.5% were farmers, and a significant portion were traders. income levels were generally low, with 35.4% earning below gh₵ 100 monthly, potentially impacting their economic access to potable water. water point sources in the district water point sources found in the district included pipe borne water, standpipe, sachet/bottled water, river/stream, rainwater, water vendor and borehole while the most preferred one was the pipe-borne water due to its potability. among the communities, it was found out that majority of the respondents in bodomase (90.2%) significantly preferred pipe borne water than respondents from kumawu, besoro and woraso. figure 2 depicts the various water point sources in the district. mapping of water points sources in the sekyere kumawu district cost distance analysis of the geographic information system was employed to map the spatial distribution of water point sources in the district. it was found that majority of the standpipes were concentrated in the kumawu community, followed by bodomase. just a few were found in the besoro and woraso communities (refer to fig 2). this distribution pattern might have been influenced by the population distribution within these. it was also observed that majority of the stand pipes were found along main roads. this was to increase accessibility of water point sources in terms of transporting them to various homes and nearby communities. there were few water point sources (pipe stands) that were disconnected due to frequent pipe burst and or failure to pay water bills. moreover, a larger number of water point sources (pipe stands) were inconsistent with the flow of water while the streams and springs were perennial in nature. global sustainability research global scientific research 66 figure 2: a map of sekyere kumawu district showing the study areas and the various water point sources source: survey and mapping division of ghana (2024) level of access of the water point sources in the district according to penchansky and thomas (1981), access refers to a degree of fit between client and system. it involves the ability (thus monetary cost) and capability (thus distance, time, convenience and energy) of an individual to reach facilities that enhances one’s wellbeing. therefore, this study measured access based on these parameters; cost, quality, time and distance. the cost of water the cost of a ‘kuffour gallon/jerry can’ of water varied with regards to quantity or size (figure 3) of the ‘gallon/jerry can’ and the income status of the area within the community. according to the manager of ghana water company limited in kumawu, “the smaller size (10 litres) of a gallon is gh0.10, the medium size (20 litres) is gh 0.20 and the bigger and longer one is gh 0.30 (25 litres)” (manager of gwcl, kumawu). an interview with a stakeholder in besoro confirmed that: “one is being sold for ghp30.” however, the price of jerry can differ with respect to communities and the type of water vendor” (assembly man, besoro). most of the water vendors in the medium and high-income areas have increased these charges to gh 0.20, gh 0.30 and gh 0.40 respectively. this affects respondents with lower income status who live such high-income areas. financially, they cannot afford this on a continuous basis because it have a huge toll on their income. global sustainability research global scientific research 67 figure 3: type of containers used for water collection and their prices pipe stands owned and managed by the ghana water company limited, charged by the standard price given (gh ¢0.30p per “large jerry can” and gh¢0.20p for the medium and gh¢0.10p for the “smaller jerry can”). this price, however, increases by gh¢ 0.10 at the private commercial pipe stands in kumawu, bodomase and besoro for profit for private operators. table 1: household monthly water expenditure amount frequency percentage gh¢1 – 50 135 57.4 gh¢51 – 100 61 25.9 gh¢101 – 150 4 1.7 gh¢151 – 200 16 6.8 gh¢201 and above 19 8.1 total 235 100 table 1 shows that majority of sampled population spent about ghc 50.00 (insert dollar equivalent) of their income on water for their homes. quite a number of them (representing 8.1%) spent more than ghc 200 and above on water monthly. most of the respondents relied on imported water and sachet water for drinking than using the normal services (pipe stand). according to the access model by penchanksy and thomas (1981), a facility or water point source is accessible if it is affordable. however, majority of the respondents spent a larger proportion of their average monthly income on water which affects their livelihood activities. table 2: respondents’ rate of affordability of water point source rate frequency percentage very affordable 28 7 affordable 80 21 not affordable 52 13 expensive 230 59 total 390 100 global sustainability research global scientific research 68 table 2 indicates that majority of respondents (59%) rated the price of the pipe-borne water as expensive. water as a basic human right should be available to all in the right quality and right quantity. however, in the sekyere kumawu district, this is not the case. according to penchanksy and thomas (1981) on access model, when a water point source is not affordable, then it is not accessible and this affects the livelihood activities of the respondents as indicated by the livelihood framework. consequently, obrist et. al (2007) posited that any constraints to access to facilities will have a major effect on the level of its accessibility. table 3: how respondents’ rated the of quality of water from the available point sources rate of quality frequency percentage good 334 85.6 salty 46 11.8 coloured 7 1.8 bad odour 3 0.8 total 390 100 according to table 3, over 85% of respondents rated the quality of water from the point sources as good (refer to table 3). this means, that the water quality was acceptable to majority of the respondents. very few of them (0.8%) had issues with the odour of the water. in the access model, acceptability of what was being accessed was crucial because this affects the rate at which something was accessed by a person. however, though quality of water was rated high, access was hindered due to the expensiveness of the cost of water. table 4: respondents’ rate of access to water facilities in the district rate of access frequency percentage easy access 345 88.5 access with some difficulties 28 7.2 access with great difficulty 5 1.3 no access 12 3.1 total 390 100 with regard to access to potable water in the district, table 4 indicates that majority of the respondents had access (less than 30 minutes) to water facilities, followed by 7.2% of respondents who had access with some difficulties (more than 30 minutes). about 3.1% of respondents could not access water from the point source facilities because of the distance in making a round trip, the topography of the area or road, and the price at which the water was sold at the point sources. table 5: time spent in accessing water per round trip community

table 5. the result χ2 (15, n=390, 94.78, p < 0.001) showed that there was a statistically significant relationship between the communities and the time respondents spent in a trip to access preferred water point source after public standpipes were installed (table 5). on average, most people spent about 11-20 minutes to access potable water per round trip. this was similar to that of strand and walker (2005) on 2600 households in latin america that found that households spent on average global sustainability research global scientific research 69 16 minutes a day to haul water. despite the proximity of water point sources, it was still not accessible because it is expensive. according to obriest et al (2007), when any of the principles of access is violated, then the facility is not accessible. measures to ensure sustainability of potable water sources to ensure the continuous supply of potable water to community members, it was imperative to put in place measures that will ensure the sustainability of these water point sources. sustainability enables the community settlers to have access to quality water in the needed quantities from these water point sources irrespective of their socioeconomic background. community members were asked to suggest best measures that should be employed to sustain these water point sources and the result was presented in table 6. they suggested that structures should be put in place by both stakeholders and institutions to ensure the sustainability of these water point sources. the traditional authorities were the main key stakeholder for the management of water sources in the district with the help of other key stakeholder institutions within the local government system. these stakeholders or institutions include the assembly members, unit committee members, youth leaders, water and sanitation committee (watsan) and the ghana water company limited (gwcl). observations revealed that there were frequent mains pipe burst in the various communities especially in kumawu and this sometimes affect the other nearby communities. also, there was no community participation with regards to plumbing works, repairing and maintenance. moreover, the watsan committee do not meet regularly. this contradicts the views of habtamu (2012) that, community participation, technology selection, site selection, demand responsiveness, construction quality, population and training, technical support, community and social satisfaction, institutional and policy, financial management and willingness to sustain the water project are the appropriate measures to sustain a water project (nkongo, 2009). on the other hand, it was found that the gwcl has adequate and needed spare parts on stock, qualified technicians and other logistics for repairs and maintenance of pipe-borne system in the district. well financial structure and controls have been inaugurated for proper accountability. accessibility to pipe-borne water connection has been increased through promotional activities. table 6: respondents’ views on ways to sustain water point sources measures frequency percentage seminars and training (education) 4 1 passing outlaws 10 2.6 attract water agencies (ngo) 3 0.8 observing and abiding rules 82 21 payment of bills 64 16.4 maintenance 135 34.6 cleanliness 92 23.6 total 390 100 more than 34% of the respondents posited that maintenance should be the centre of sustainability. however, the assembly members and traditional authorities were reserved with regards to maintenance of the water point sources especially the public pipe stands since there was weak community participation on the project. one respondent in an interview maintained that; “they have their own plumbers. i do not know any trained person from this town. after logging complains, we would have to wait for them to come around. the logged problem cannot be attended to unless the water works do that. the plumbers in this town are not allowed to attend to issues relating to waterworks since they are not their workers. even if the pipes burst, we wait for them to attend to them. the local plumbers are not allowed to connect conduits to various homes. i do not know why it is like that. dealing with the waterworks comes with a higher cost” (male, 35 years, married with 2 children assemblyman, besoro). therefore, it was proposed that the ghana water company trained the plumbers in the various communities and assigned specific roles or area of specialisation to the trained local technical men to effectively operate and global sustainability research global scientific research 70 maintenance water systems in the various communities. this will promote community participation and involvement to the use and maintenance of the project. quite a number of the respondents (23.6%) maintained that these water point sources needed to be kept clean to promote its sustainability. both the pipe-borne water, and water point sources such as streams and rivers should be cleaned from time to time. one of the assembly members (35 years old, married man with 2 kids) highlighted that; “i have not seen the dam personally. all they need to do is to protect the dam very well from getting silted. if the dam gets blocked with silt and litre, then the government would have done a “cos 90” work. they have to remove all the blockages from the dam almost every two years. there is a possibility of filling the dam. hence, they need to make sure these silt and plastic wastes do not choke the dam. also, looking at how things are going with the pipelines bursting each now and then, a time is coming when all the pipes will not flow at kumawu to the extent that all the pipelines will be damaged. hence, changing them may take years to complete”. (assemblyman, besoro). rules regarding proper management of water sources cannot be overlooked. though the majority of the households were silent on the enactment of laws to govern the use and management of water point sources, the focus was on its adherence by community members. the management of ghana water company limited in kumawu buttressed this by saying that: “people are aware of the rules and regulations governing the protection of our pipeline network. some people however, build on our pipelines network which is very bad. they always get away with these actions because nobody does anything to stop them. this exerts a lot of pressure on our pipelines causing frequent pipe burst.” (manager of gwcl, kumawu). pipe-borne connection to homes most of the respondents (61.3%) do not have pipe borne water connection to their various homes due to high cost of connection, cumbersome procedure and difficulties in connecting to various homes because of the topography or landscape of the area. among the communities, most of the respondents from bodomase were connected to pipe-borne water as compared with respondents in woraso. further analysis to understand where household’s income had any relationship with pipeborne connection to homes, a chi-square test of goodness-of-fit was run. the results in table 7 (χ2 (4, n=390, 20.73, p < 0.001) depicted that there was no statistically significant difference between income status and pipe-borne connection to the home. it was found that most of the respondents who earned gh¢ 400.00 and more had pipe-borne connection to their homes as compared to respondents who earned below gh¢100.00. the cost of connection was a bit high, especially among those who were far away from the main lane and hilly areas, making people who earned less than gh400 less likely to afford it. table 7: distance and to access potable water before and after pipe borne water connection distance per trip n mean std dev. statistic before pipe stand 239 2.45 1.25 t=12.61 p<0.001 df=238 after pipe stand 239 1.31 0.64 the t-test was employed in analysing the effect of the intervention project (3k project) on access to potable water the result (t(238)= 12.063, p<0.001) showed that there was statistical significant difference between the distance that respondents covered to access potable water before and after the public stand pipes were installed (refer to table 7). this implied that the people of sekyere kumawu district now covered shorter distances to access potable compared to times prior to the installation of public stand pipes. among the communities, respondents in kumawu now journeyed a very short distance to access water as compared with other communities. this difference was statistically significant as it was proven by a chi-square test of goodness-of-fit and the result χ2 (9, n=390, 19.31, p = 0.023). regardless of the enhanced proximity to pipestands, some people in woraso still prefer other water point sources such as “asuo kumawu” (spring) due to its taste among others. studies have shown that reducing the distance to water sources significantly improves water access and usage. for instance, a study by kremer et al. global sustainability research global scientific research 71 (2011) found that providing closer access to water sources in kenya increased water consumption and improved health outcomes. similarly, research by cairncross and valdmanis (2006) noted that shorter distances to water sources directly correlate with better water quality and reduced waterborne diseases. conclusions and recommendations the people of sekyere kumawu district only have access to basic drinking water services due to expensive nature of pipe-borne water system. among the water point sources such as pipe borne water, sachet/bottled water, river/stream, rainwater and water from mobile water venders, the people of sekyere kumawu preferred pipe-borne water for drinking. regardless of the hitches and challenges faced by ghana water company limited, they have been able to improve upon water accessibility in the district. needed spare parts have been secured, qualified technicians, mobile collection service has been constituted, some springs have been fenced, watsan committee has be formed, promotion for pipe borne connection to peoples’ various homes have been introduced. however, the ghana water company limited is understaffed. this caused delays in connection of pipe-borne water, repairs and maintenance of faulty or burst pipes. the district assembly should liaise with water and sanitation ngos and gwcl to finance water projects expansion within the communities, especially areas where there were spatially deficiency in the water point sources or under-coverage and to newly developed areas in a bid to improve accessibility, especially to access safely managed drinking water services. the purc should collaborate with gwcl to come out with some kind of subsidy package that will also last long to ease households’ burden of connecting to the main lines and also to make standpipes affordable. the ghana water company limited should ensure a little community participation by training the local technicians such as plumbers and engineers and specify the kind and area of work they can address in the various communities with regards to the pipe-borne water connection and related issues. this will prevent frequent breakdown of pipe borne water system, reduce the workload of their staffs and technicians and loss of water due to frequent burst among others. finally, some structures were put up on the pipe lanes and little attention was given to streams, rivers and springs. the works department of the assembly may partner with the watsan, gwcl and ghana police to ensure that people adhere to the rules and regulations governing the use and management of pipe borne water. the sekyere kumawu district assembly should liase with the traditional council and watsan to educate and sensitize the households to protect water supply sources such as rivers, strings and streams by managing the available water sheds and reduce the cutting of trees along banks.

programs. keywords: sustainable finance; comparative analysis; asia; africa; global sustainability and capacity building introduction the global community recognizes the urgent need for sustainable development practices to tackle environmental and social challenges. sustainable finance has emerged as a crucial tool in mobilizing financial resources for ecofriendly and socially responsible projects. by integrating sustainability into investment decisions, it aims to drive positive economic, social, and environmental outcomes (unep, 2020; world bank, 2021). asia and africa, characterized by diverse economies and developmental challenges, have witnessed significant traction in sustainable finance initiatives. these continents experience rapid economic growth, industrialization, and urbanization, leading to environmental risks and social inequalities (adb, 2019; afdb, 2022). governments, financial institutions, and businesses in asia have introduced policies and frameworks to incentivize sustainable investments (adb, 2020; gri, 2021). initiatives like green bonds, sustainable lending, and impact investing have gained momentum, directing funds towards climate change mitigation and sustainable infrastructure (unescap, 2021; ifc, 2022). in africa, sustainable finance initiatives address socioeconomic disparities and environmental vulnerabilities (afdb, 2021). governments, international organizations, and financial institutions recognize sustainable finance's role in unlocking the continent's potential and achieving sustainable development goals (uneca, 2020; iucn, 2021). activities include microfinance for rural communities, innovative climate adaptation financing, and partnerships for sustainable agriculture and natural resource management (undp, 2020; gcf, 2022). global sustainability research global scientific research 34 understanding the context of sustainable finance initiatives in asia and africa is crucial to comprehend motivations, challenges, and opportunities (escap, 2022; unep fi, 2022). factors like governance, regulations, access to capital, technology, and culture influence outcomes (world bank, 2020; ilo, 2021). a comparative analysis offers valuable insights, identifying successful models and sharing best practices to foster global sustainability (unep fi, 2021; afdb, 2020). this article will delve into specific sustainable finance initiatives in asia and africa, conduct a comparative analysis of their impact, and explore collaboration avenues for a sustainable future. statement of the problem despite the growing momentum of sustainable finance initiatives in asia and africa, several challenges hinder the effective implementation and scale-up of these efforts. understanding and addressing these challenges is essential for achieving the desired outcomes of sustainable finance and advancing global sustainability goals. one of the key challenges is the lack of harmonized regulatory frameworks and policy incentives for sustainable finance across countries within each region and between asia and africa. while individual countries have made strides in developing their sustainable finance policies, the absence of a standardized approach hampers cross-border investments and limits the scalability of sustainable finance initiatives. for instance, in asia, countries such as china and india have introduced their own green bond guidelines and sustainable finance regulations (people's bank of china, 2015; securities and exchange board of india, 2020), but there is a need for greater alignment and coordination to facilitate regional collaboration. in africa, the absence of comprehensive sustainable finance policies and the limited availability of financing options pose significant challenges. many african countries lack the necessary regulatory frameworks and institutional capacity to promote sustainable finance effectively. however, there have been notable efforts to address this issue. the african development bank's sustainable finance framework (african development bank, 2014) and the african union's agenda 2063 (african union, 2015) provide strategic guidance for integrating sustainability into financial systems, but implementation at the national level remains a challenge. another critical challenge is the limited awareness and understanding of sustainable finance among various stakeholders, including financial institutions, investors, and businesses. despite the growing interest in sustainable finance, there is still a lack of knowledge and capacity to assess and incorporate sustainability factors into investment decisions effectively. enhancing financial literacy and promoting capacity-building programs are essential to ensure informed decision-making and promote sustainable finance practices. the united nations environment programme's principles for responsible banking (united nations environment programme finance initiative, 2019) and the international finance corporation's performance standards on environmental and social sustainability (international finance corporation, 2012) outline guidelines for financial institutions to integrate sustainability into their operations. however, there is a need for greater dissemination and implementation of these principles across asia and africa. furthermore, the availability of reliable and standardized data for assessing the environmental and social impact of sustainable finance initiatives remains a challenge. access to accurate data is crucial for measuring progress, conducting impact assessments, and ensuring transparency and accountability. efforts such as the task force on climate-related financial disclosures (tcfd, 2017) have made strides in promoting climate-related data disclosure, but there is a need for similar initiatives focused on broader sustainability metrics. addressing these challenges requires concerted efforts from governments, financial institutions, and international organizations to develop and implement comprehensive regulatory frameworks, enhance capacity-building initiatives, and promote data transparency. collaboration between asia and africa can play a pivotal role in sharing experiences, exchanging best practices, and collectively addressing these challenges to accelerate the transition towards sustainable finance and global sustainability. in the subsequent sections, this article will explore the specific sustainable finance initiatives in asia and africa, conduct a comparative analysis of their impact and effectiveness, and propose recommendations for addressing the identified challenges. by referencing real policy documents and frameworks, this article aims to provide a robust and evidence-based analysis of the problem at hand. global sustainability research global scientific research 35 research objectives and scope the primary objective of this research is to conduct a comparative analysis of sustainable finance initiatives in asia and africa, with a focus on their contribution to global sustainability. the study aims to explore the similarities, differences, challenges, and opportunities associated with sustainable finance practices in both regions. by examining the progress, impact, and effectiveness of these initiatives, the research seeks to identify lessons learned, best practices, and areas for improvement. the specific research objectives are as follows: to examine the current state of sustainable finance initiatives in asia and africa, including an overview of the policies, regulations, and frameworks implemented by governments, financial institutions, and international organizations. 1. to identify and analyze successful case studies of sustainable finance models in asia and africa, showcasing examples of effective implementation and positive outcomes. 2. to compare and contrast the key similarities and differences between sustainable finance initiatives in asia and africa, considering factors such as governance structures, regulatory frameworks, access to capital, technological advancements, and cultural norms. 3. to assess the impact and effectiveness of sustainable finance initiatives in both regions, evaluating their contribution to environmental sustainability, social development, and economic resilience. 4. to identify the challenges and barriers faced by sustainable finance initiatives in asia and africa, including regulatory gaps, capacity constraints, limited awareness, and data availability. 5. to propose recommendations and strategies for enhancing sustainable finance practices in both regions, taking into account the identified challenges and leveraging potential synergies between asia and africa. the research scope encompasses an analysis of sustainable finance initiatives implemented by various stakeholders, including governments, financial institutions, and international organizations, in asia and africa. it covers a wide range of sustainable finance mechanisms, such as green bonds, sustainable lending, impact investing, and innovative financing mechanisms for sustainable development projects. the study will primarily rely on a comprehensive review of existing literature, policy documents, reports, and case studies related to sustainable finance initiatives in asia and africa. data analysis and qualitative research methods will be employed to examine the impact and effectiveness of these initiatives. however, it is important to note that this research will not delve into specific financial market dynamics or conduct a comprehensive financial analysis of individual countries or institutions. by fulfilling these research objectives within the defined scope, this study aims to contribute to the existing knowledge on sustainable finance in asia and africa, provide insights for policymakers, practitioners, and researchers, and offer recommendations to advance the path towards global sustainability. literature review sustainable finance initiatives in asia overview of sustainable finance in asia asia has witnessed a significant rise in sustainable finance initiatives, driven by the region's growing recognition of the need to address environmental and social challenges while fostering economic growth. this section provides an overview of sustainable finance in asia, highlighting key trends, regulatory frameworks, and regional initiatives. asian countries are increasingly adopting policies and regulations that promote sustainable finance practices. for instance, china has made substantial progress in integrating environmental considerations into its financial system. the people's bank of china has issued guidelines on green finance and established a green bond market, facilitating investments in renewable energy, energy efficiency, and pollution control (people's bank of china, 2016). similarly, in india, the securities and exchange board of india (sebi) has introduced guidelines for the issuance of green bonds, encouraging companies to raise capital for sustainable projects. additionally, the reserve bank of india has implemented a sustainable finance framework to promote green lending and sustainability-linked loans (securities and exchange board of india, 2017; reserve bank of india, 2020). japan has been at the forefront of sustainable finance in asia, with a long history of promoting environmentally and global sustainability research global scientific research 36 socially responsible investments. the japan sustainable investment forum (jsif) has been instrumental in driving sustainable finance practices, bringing together investors, companies, and policymakers to collaborate on sustainable investment strategies (japan sustainable investment forum, n.d.). regional initiatives in asia are also playing a crucial role in advancing sustainable finance. the association of southeast asian nations (asean) has established the asean green bond standards, providing guidelines for issuers and investors in the region. this initiative aims to facilitate the development of a robust green bond market in southeast asia (asean capital markets forum, 2017). furthermore, the asian development bank (adb) has been actively promoting sustainable finance in the region. the adb's action plan for sustainable finance outlines strategies to mobilize resources for sustainable infrastructure, enhance climate and environmental risk management, and promote financial inclusion (asian development bank, 2017). asian financial institutions are increasingly incorporating sustainability considerations into their operations. for example, the development bank of singapore (dbs) has implemented a sustainable finance framework, guiding its lending and investment activities towards sustainable projects (development bank of singapore, 2019). in summary, asia is experiencing a significant surge in sustainable finance initiatives, driven by regulatory frameworks, regional initiatives, and the proactive engagement of financial institutions. countries like china, india, and japan are leading the way in integrating sustainable finance practices into their financial systems. regional collaborations and initiatives by organizations such as asean and adb further support the development of sustainable finance in asia, contributing to the region's transition towards a more sustainable and resilient future. sustainable finance initiatives in asia asia has witnessed a surge in sustainable finance initiatives, with various countries and organizations in the region actively promoting environmentally and socially responsible investment practices. this section provides an overview of key sustainable finance initiatives in asia, highlighting specific projects and programs that have made significant contributions to the region's sustainability goals. china, as the world's largest emitter of greenhouse gases, has taken substantial steps to advance sustainable finance. one noteworthy initiative is the establishment of the green finance committee (gfc) by the china society for finance and banking. the gfc aims to promote green finance practices, conduct research, and facilitate knowledge sharing among financial institutions (china society for finance and banking, n.d.). in india, the indian renewable energy development agency (ireda) plays a crucial role in promoting sustainable finance. ireda provides financial assistance and incentives for renewable energy projects, including solar, wind, and hydroelectric power. by offering favorable loan terms and financial support, ireda has played a significant role in facilitating the growth of renewable energy investments in india (indian renewable energy development agency, n.d.). japan has been a leader in sustainable finance initiatives, particularly through the issuance of green bonds. one prominent example is the issuance of green bonds by the tokyo metropolitan government. the proceeds from these bonds are allocated to projects aimed at reducing greenhouse gas emissions, improving energy efficiency, and promoting environmental conservation (tokyo metropolitan government, n.d.). the monetary authority of singapore (mas) has also made significant efforts to foster sustainable finance in the region. mas launched the green finance action plan in 2019, with the aim of developing singapore as a leading hub for green finance. the plan includes initiatives such as introducing a green bond grant scheme and developing guidelines for sustainability-linked loans, encouraging financial institutions to incorporate sustainability considerations into their lending practices (monetary authority of singapore, 2019). regional collaborations have also played a crucial role in promoting sustainable finance in asia. the asian infrastructure investment bank (aiib) has been actively financing sustainable infrastructure projects across the region. through its sustainable energy for asia strategy, the aiib supports investments in renewable energy, energy efficiency, and low-carbon transportation projects (asian infrastructure investment bank, 2022.). in summary, sustainable finance initiatives in asia are diverse and multifaceted, with various countries and organizations driving the adoption of environmentally and socially responsible investment practices. initiatives such as the green finance committee in china, the indian renewable energy development agency in india, and the issuance of green bonds in japan have demonstrated the region's commitment to sustainable finance. regional global sustainability research global scientific research 37 collaborations, exemplified by the efforts of the monetary authority of singapore and the asian infrastructure investment bank, further contribute to the growth and development of sustainable finance in asia. case studies: successful sustainable finance models in asia asia has witnessed the emergence of successful sustainable finance models that have demonstrated the viability and effectiveness of integrating environmental and social considerations into financial practices. this section presents case studies of notable sustainable finance models in asia, showcasing their innovative approaches and positive impacts on sustainable development. case study 1: the green energy financing model in china china has been at the forefront of sustainable finance, particularly in the renewable energy sector. the green energy financing model, implemented by the industrial and commercial bank of china (icbc), has successfully facilitated the financing of renewable energy projects. through this model, icbc provides long-term, lowinterest loans to renewable energy companies, incentivizing investment in solar, wind, and hydroelectric power projects. this has led to a significant increase in renewable energy capacity and a reduction in carbon emissions in china (world resources institute, 2018). case study 2: sustainable microfinance in bangladesh grameen bank, founded by nobel laureate muhammad yunus, has pioneered sustainable microfinance in bangladesh. by providing small loans to low-income individuals, particularly women, grameen bank enables them to start sustainable businesses and improve their livelihoods. the bank incorporates social and environmental considerations into its lending practices, emphasizing projects that promote renewable energy, sustainable agriculture, and clean water access. this sustainable microfinance model has not only lifted many people out of poverty but also contributed to environmental conservation and social empowerment (grameen bank, n.d.). case study 3: green bond initiatives in singapore singapore has embraced green finance, and several successful green bond initiatives have been launched in the country. one notable example is the issuance of green bonds by capitaland limited, a real estate company. the proceeds from these bonds are allocated to financing and refinancing green buildings and sustainable development projects. capitaland's green bond initiatives have contributed to the construction of energy-efficient buildings, reduced carbon emissions, and enhanced sustainable urban development in singapore (capitaland limited, 2020). case study 4: sustainable infrastructure financing in india india's national investment and infrastructure fund (niif) has played a pivotal role in promoting sustainable infrastructure financing in the country. the niif has established the niif green growth equity fund (ggf), which focuses on investments in green infrastructure projects, such as renewable energy, clean transportation, and waste management. by attracting private investments and providing capital for sustainable infrastructure, the ggf has accelerated india's transition towards a lowcarbon economy (national investment and infrastructure fund, n.d.). these case studies highlight successful sustainable finance models in asia that have demonstrated tangible environmental and social benefits. the green energy financing model in china, sustainable microfinance in bangladesh, green bond initiatives in singapore, and sustainable infrastructure financing in india exemplify innovative approaches to integrating sustainability into financial practices. challenges and opportunities in asian sustainable finance initiatives asia's sustainable finance initiatives face several challenges, but they also present significant opportunities for transformative change. one key challenge is the limited awareness and understanding of sustainable finance among stakeholders. many financial institutions, investors, and the general public in asia lack awareness of the potential benefits and financial opportunities that sustainable finance offers (united nations environment programme, 2018). this highlights the need for increased awareness campaigns and educational programs to promote understanding and adoption of sustainable finance principles. another challenge lies in the establishment of consistent regulatory frameworks and standards across asian global sustainability research global scientific research 38 countries. harmonized regulations and standardized sustainability reporting requirements are crucial for ensuring transparency and comparability of sustainable finance initiatives. developing clear guidelines will provide a common foundation and encourage the integration of environmental, social, and governance (esg) factors into financial decision-making (financial stability board, 2020). access to financing is a persistent challenge, particularly for small and medium-sized enterprises (smes) and projects in less developed regions. limited access to affordable capital, lack of collateral, and high transaction costs hinder the flow of funds to sustainable projects. addressing these barriers requires innovative financing mechanisms, such as blended finance models and targeted financial support for underserved sectors (asian development bank, 2021). despite these challenges, there are significant opportunities to further enhance sustainable finance initiatives in asia. the issuance of green bonds and the development of sustainable investment products offer avenues to mobilize capital for climate-friendly projects. green bonds have gained traction globally and can attract investments specifically earmarked for environmental initiatives. moreover, the creation of sustainable investment products, such as green funds and sustainability-themed indexes, can cater to the growing demand for socially and environmentally responsible investment options (climate bonds initiative, 2021). collaboration and knowledge sharing are critical drivers of progress in sustainable finance. encouraging collaboration among stakeholders, including financial institutions, governments, academia, and civil society, can foster knowledge sharing, capacity building, and the adoption of best practices. regional collaborations, partnerships, and knowledge-sharing platforms can facilitate the exchange of experiences and accelerate the growth of sustainable finance in asia (sustainable finance study group, 2020). technology integration also offers immense opportunities for advancing sustainable finance in asia. leveraging technologies such as blockchain, artificial intelligence, and data analytics can enhance efficiency, transparency, and risk assessment in sustainable finance practices. these technologies can enable better assessment of environmental and social risks, improve the tracking of funds, and facilitate the verification of sustainable outcomes (united nations economic and social commission for asia and the pacific, 2019). by addressing the challenges and embracing the opportunities, asian countries can unlock the full potential of sustainable finance and pave the way for a more sustainable and resilient future. sustainable finance initiatives in africa overview of sustainable finance sustainable finance is a critical component of achieving global sustainability goals, and africa has been making significant strides in this area. the continent is increasingly recognizing the importance of integrating environmental, social, and governance (esg) factors into financial practices to drive sustainable development. this section provides an overview of sustainable finance in africa, highlighting key initiatives and trends. in recent years, african countries have witnessed the emergence of sustainable finance frameworks and policies that promote responsible investment and sustainable economic growth. the african development bank (afdb) has been at the forefront of sustainable finance initiatives on the continent. the bank has developed several programs and financing mechanisms aimed at supporting sustainable projects, such as renewable energy, climate resilience, and sustainable infrastructure (african development bank, 2023). one notable sustainable finance initiative in africa is the establishment of green bonds. green bonds provide a mechanism for raising capital specifically for environmentally friendly projects. south africa, nigeria, and kenya have been pioneers in issuing green bonds to finance renewable energy projects, sustainable agriculture, and climate change adaptation initiatives (climate bonds initiative, 2021). these green bond issuances not only attract domestic and international investors but also contribute to addressing africa's pressing environmental challenges. another significant trend in african sustainable finance is the rise of impact investing. impact investing involves directing investments towards projects and companies that generate positive social and environmental outcomes alongside financial returns. impact investors in africa are actively seeking opportunities that align with the united nations sustainable development goals (sdgs) to address pressing social and environmental issues while driving economic growth (global impact investing network, 2021). global sustainability research global scientific research 39 furthermore, african financial institutions are increasingly incorporating esg considerations into their investment decision-making processes. this integration involves assessing the environmental and social risks and opportunities associated with investments, as well as considering corporate governance practices. by incorporating esg factors, african financial institutions are not only promoting sustainable practices but also mitigating risks and enhancing long-term financial performance (united nations economic commission for africa, 2021). however, despite the progress made, africa faces several challenges in advancing sustainable finance. limited access to finance, inadequate regulatory frameworks, and lack of awareness and capacity are some of the obstacles hindering the widespread adoption of sustainable finance practices across the continent. addressing these challenges requires collaborative efforts among governments, financial institutions, and international organizations to develop supportive policies, improve financial infrastructure, and enhance awareness and capacitybuilding initiatives (united nations environment programme, 2020). in conclusion, africa is witnessing a growing momentum in sustainable finance, with initiatives such as green bonds, impact investing, and the integration of esg factors gaining traction. the continent's commitment to sustainable development, along with targeted policies and collaborative efforts, will be key in unlocking the full potential of sustainable finance in africa and driving positive environmental, social, and economic outcomes. sustainable finance initiatives in africa africa is witnessing a growing emphasis on sustainable finance, with various initiatives aimed at promoting responsible investment and driving sustainable development on the continent. this section provides an overview of sustainable finance initiatives in africa, highlighting key programs and trends. the african development bank (afdb) has been instrumental in driving sustainable finance initiatives across africa. the bank has launched several programs and financing mechanisms to support sustainable projects and foster economic growth. one notable initiative is the africa green growth fund, which provides financial and technical support to projects focused on renewable energy, climate adaptation, and sustainable infrastructure (african development bank, 2021). the afdb's commitment to sustainable finance plays a vital role in mobilizing resources and fostering collaboration among stakeholders in africa. in addition to the afdb's efforts, african countries are increasingly recognizing the importance of sustainable finance and incorporating it into their national agendas. many countries have developed national sustainable finance frameworks and policies to promote responsible investment and environmental stewardship. for example, kenya has implemented the green economy strategy and implementation plan, which aims to mobilize investments for sustainable sectors and transition to a low-carbon, resource-efficient economy (republic of kenya, 2012). green bonds have gained significant traction in africa as a means to finance sustainable projects. south africa, nigeria, and kenya have been at the forefront of green bond issuances on the continent. for instance, south africa's eskom issued the continent's first green bond in 2019 to fund renewable energy projects, while nigeria's access bank and kenya's nairobi securities exchange have also successfully issued green bonds (climate bonds initiative, 2021). these green bond initiatives attract both domestic and international investors and contribute to addressing africa's environmental challenges. furthermore, impact investing is gaining momentum in africa. impact investing involves directing investments towards projects and enterprises that generate measurable social and environmental impacts alongside financial returns. africa's rich social and environmental challenges provide ample opportunities for impact investors to drive positive change. impact investment funds, such as the african agriculture impact investment fund, focus on supporting sustainable agriculture, improving food security, and empowering rural communities (global impact investing network, 2021). these initiatives not only generate financial returns but also create tangible social and environmental benefits. despite the progress, africa still faces challenges in scaling up sustainable finance initiatives. limited access to finance, inadequate regulatory frameworks, and the need for capacity-building are key barriers that need to be addressed. collaboration between governments, financial institutions, and international organizations is crucial in developing enabling policies, improving financial infrastructure, and enhancing awareness and knowledge sharing (united nations environment programme, 2020). in conclusion, sustainable finance initiatives in africa are gaining momentum, driven by the efforts of organizations like the african development bank and national global sustainability research global scientific research 40 governments. green bonds and impact investing are playing pivotal roles in mobilizing capital for sustainable projects and generating positive social and environmental impacts. however, addressing the challenges and fostering collaboration will be essential in realizing the full potential of sustainable finance in africa and driving inclusive and sustainable development across the continent. case studies: successful sustainable finance models in africa africa has witnessed the emergence of several successful sustainable finance models that showcase the continent's commitment to addressing environmental and social challenges while promoting economic growth. these case studies demonstrate the effectiveness of sustainable finance in driving positive impact and transforming industries. case study 1: m-kopa solar a revolutionary payas-you-go solar model

contributing to reduced reliance on fossil fuels and improved energy access for rural populations (gallagher, 2017). case study 2: nedbank's green bond financing renewable energy projects nedbank, one of south africa's largest banks, issued africa's first corporate green bond in 2019. the bond raised 1.7 billion south african rand (approximately $120 million) and was earmarked for financing renewable energy and energy-efficient projects. the bond's proceeds supported projects that promote sustainability and reduce carbon emissions, including renewable energy installations and energy-efficient buildings (nedbank, 2019). by issuing the green bond, nedbank demonstrated its commitment to sustainable finance and catalyzed investments in environmentally friendly projects. the bond attracted investors seeking both financial returns and positive environmental impacts. the success of nedbank's green bond has paved the way for other financial institutions in africa to explore sustainable debt instruments and mobilize capital for climate-friendly initiatives (pereira, 2019). case study 3: rwanda's green growth strategy integrating sustainable finance in national development rwanda has made remarkable progress in promoting sustainable finance at the national level. the country's green growth strategy is a comprehensive framework that integrates sustainable finance principles into its development agenda. rwanda's strategy includes a dedicated green fund, the rwanda green fund (fonerwa), which finances projects aligned with the country's climate and environmental objectives (government of rwanda, 2011). fonerwa has been instrumental in supporting projects in various sectors, such as renewable energy, sustainable agriculture, and waste management. the fund mobilizes both domestic and international investments to drive green initiatives and create a sustainable future for rwanda. by prioritizing sustainable finance, rwanda is demonstrating how integrating environmental considerations into national development planning can drive positive outcomes for both people and the planet (fonerwa, 2021). in conclusion, these case studies exemplify successful sustainable finance models in africa that have delivered tangible environmental and social benefits. m-kopa solar's pay-as-you-go solar model has expanded energy access to off-grid households, nedbank's green bond has mobilized funds for renewable energy projects, and rwanda's green growth strategy has integrated sustainable finance principles into national development planning. these examples showcase the transformative power of sustainable finance in africa, demonstrating its potential to drive inclusive and sustainable development across the continent. global sustainability research global scientific research 41 challenges and opportunities in african sustainable finance initiatives africa's sustainable finance initiatives face a range of challenges and opportunities that shape their future trajectory. overcoming these obstacles and capitalizing on the potential opportunities will be crucial for the advancement and success of sustainable finance in africa. one of the primary challenges facing sustainable finance initiatives in africa is the limited access to finance for many individuals and businesses. financial inclusion remains a significant hurdle, particularly for small and medium-sized enterprises (smes) and rural communities. the lack of accessible financial services hinders the adoption of sustainable practices, as financial resources are often required to implement environmentally friendly projects. innovative financial products and services that cater to the needs of underserved populations are necessary to address this challenge and unlock the potential of sustainable finance in africa (united nations economic commission for africa, 2021). inadequate regulatory frameworks pose another obstacle to the growth of sustainable finance in africa. many african countries face regulatory gaps and inconsistencies that deter investors and financial institutions from engaging in sustainable projects. the absence of clear and supportive policies hampers the flow of investments into sustainable initiatives. to foster sustainable finance, it is essential to harmonize regulatory frameworks across countries and create an enabling environment that encourages and supports sustainable investments (african development bank, 2021). lack of awareness and capacity among stakeholders is also a significant barrier to the widespread adoption of sustainable finance in africa. many businesses, investors, and policymakers may not fully understand the potential benefits and mechanisms of sustainable finance. to address this, capacity-building programs, workshops, and educational campaigns are necessary to enhance knowledge and awareness of sustainable finance practices. increasing awareness and building the necessary capacity will help stakeholders embrace sustainable finance principles and drive sustainable development on the continent (united nations environment programme, 2020). despite these challenges, african sustainable finance initiatives offer significant opportunities for driving positive change and fostering sustainable development. africa's abundance of natural resources presents an opportunity to leverage sustainable finance for investments in renewable energy, sustainable agriculture, and responsible mining. by directing capital towards these sectors, economic growth can be

rural communities, innovative climate adaptation financing, and partnerships for sustainable agriculture and natural resource management (undp, 2020; gcf, 2022). these endeavors reflect africa's commitment to addressing social inequalities and environmental vulnerabilities and leveraging sustainable finance as a means of inclusive growth and resilience. by collaborating and leveraging each other's experiences and strengths, asia and africa can create synergies that drive progress towards global sustainability (afdb, 2021; uneca, 2020). knowledge exchange and joint initiatives between the two regions can facilitate the sharing of best practices, successful models, and lessons learned, fostering a collective effort towards sustainable development goals (iucn, 2021; gri, 2021). to enhance sustainable finance on a global scale, it is imperative to develop clear regulatory frameworks that provide certainty and stability for investors and businesses alike (world bank, 2021; ifc, 2022). effective regulations can help create an enabling environment for sustainable finance to thrive and ensure alignment with broader sustainability objectives. additionally, promoting sustainable practices within financial institutions, such as integrating environmental, social, and governance (esg) considerations into decision-making processes, can further embed sustainability in the core of financial activities (adb, 2020; unep fi, 2021). encouraging transparency and accountability in reporting on sustainable finance initiatives will also bolster stakeholders' confidence and facilitate effective impact measurement and evaluation (gri, 2021; unescap, 2022). capacity building is equally crucial in the journey towards sustainable finance success (uneca, 2020; undp, 2020). by investing in comprehensive programs that equip stakeholders with the necessary knowledge and skills, governments, financial institutions, and businesses can navigate the complexities of sustainable finance and maximize its potential for positive change. capacity building efforts should encompass various stakeholders, including policymakers, financial professionals, and community leaders, to build a holistic understanding and drive collective action (iucn, 2021; ifc, 2022). the future of sustainable finance holds immense promise and potential (unep, 2020; adb, 2020). trends such as the continued issuance of green and sustainable bonds will mobilize significant funds towards environmental and socially responsible projects (unep, 2020; ifc, 2022). furthermore, technology-driven solutions, such as fintech innovations, can play a pivotal role in enhancing the efficiency and accessibility of sustainable finance (unescap, 2022; world bank, 2021). these technological advancements can facilitate financial inclusion and promote sustainable investments in previously underserved areas. impact measurement and reporting will also gain prominence as stakeholders increasingly seek to assess the tangible outcomes of sustainable finance initiatives (gri, 2021; unep fi, 2021). accurate and transparent reporting global sustainability research global scientific research 47 will help build trust among investors and consumers, fostering greater participation in sustainable finance efforts. additionally, the integration of esg factors into investment decisions will become more widespread, aligning financial interests with broader sustainability goals (adb, 2020; gri, 2021). as investors recognize the long-term value of environmentally and socially responsible investments, sustainable finance will become a mainstream practice. in conclusion, by embracing the recommendations and trends outlined in this study, stakeholders in asia and africa, and beyond, can drive positive change, mobilize investments, and build a more sustainable future for all (undp, 2020; unescap, 2022). collaborative efforts, guided by clear regulatory frameworks, sustainable practices, and capacity building, will pave the way for transformative sustainable finance initiatives (iucn, 2021; unep, 2020). together, asia and africa, as well as the global community, can navigate the challenges of sustainable development and embrace the opportunities for a more sustainable and inclusive world. acknowledgment: the authors would like to express their sincere appreciation to fatima adam labaran

agri-fintech; financial inclusion; smallholder farmers; agriculture in pakistan; sustainable development introduction the emergence of financial technology (fintech) and the digital economy has garnered significant interest from businesses, academia, and various public and private entities. fintech represents a pivotal concept and implementation that have stimulated research across diverse disciplines, including agriculture and farming. in the pursuit of sustainability and enhanced productivity, smart connectivity plays a vital role, facilitated by the digital marketplace. this platform enables novel forms of communication and transactions among the numerous stakeholders engaged in agricultural operations, encompassing consumers, suppliers, farmers, investors, distributors, and others involved in the agricultural business landscape (anshari et al., 2019). agriculture, primarily in developing nations, faces difficulties with typical business processes due to cash shortages, capital problems, restricted access to financial institutions, and a lack of market access. the supply chains in agriculture have numerous layers, from farmers to consumers, adding to the cost of the product (anshari & alas, 2015). a digital marketplace that supports fintech could improve agriculture. demand shifts will be hastened by the digital market, which will increase consumer interest in foods from various regions. as a result, incorporating fintech into the digital marketplace might solve the regular problems with farmers' finances and encourage the public to participate in agriculture (anshari & lim, 2017). global sustainability research global scientific research 61 moreover, financial inclusion has emerged as a critical factor in promoting sustainable economic growth and reducing poverty, particularly in developing countries like pakistan (demirgüç-kunt et al., 2018). the agriculture sector, which plays a pivotal role in pakistan's economy, is largely characterized by smallholder farmers, who often face significant barriers to accessing formal financial services (world bank, 2019). this paper seeks to explore the potential of fintech solutions to increase financial inclusion for these smallholder farmers and other stakeholders in pakistan's agriculture sector. in pursuit of the research objective, a thematic literature review methodology was implemented. the current study delves into the identification of effective and sustainable fintech solutions as well as the challenges and opportunities for scaling up these innovations (creswell et al., 2017). the research sheds light on the transformative potential of digital platforms for loans, payments, and market linkages in increasing access to finance and other financial services for farmers (buku & meredith, 2018). literature review the literature on financial inclusion and the role of fintech in promoting access to financial services for smallholder farmers has grown substantially in recent years. this literature review aims to synthesize the current body of knowledge on the potential of fintech solutions to foster financial inclusion for smallholder farmers and other underserved communities, particularly in the context of pakistan's agriculture sector. by examining the barriers faced by smallholder farmers in accessing formal financial services, the emergence of fintech solutions, the importance of trust and transparency, and the need for collaboration between the fintech and agriculture sectors, this review provides a comprehensive understanding of the challenges and opportunities for leveraging fintech to enhance financial inclusion in the agriculture sector. financial inclusion and smallholder farmers financial inclusion, the process of ensuring access to and usage of formal financial services by all individuals and businesses, has been widely acknowledged as a crucial factor in reducing poverty, promoting sustainable economic growth, and enhancing overall wellbeing (demirgüç-kunt et al., 2018; karlan et al., 2016; cgap, 2020). the significance of financial inclusion is particularly notable for smallholder farmers in developing countries like pakistan, who often face considerable barriers to accessing formal financial services, including savings, credit, insurance, and payment systems (world bank, 2019; ifad, 2019). smallholder farmers are a critical population, representing the majority of the agriculture sector and contributing to food security and poverty reduction (fao, 2017; agra, 2020). they play an essential role in ensuring the resilience of rural communities and maintaining the stability of local food systems (lowder, skoet, & raney, 2016). however, limited access to credit, insurance, and other financial services inhibits their productivity and growth potential (pakistan bureau of statistics, 2021; cole, sampson, & zia, 2011). access to financial services is critical for smallholder farmers to invest in productivity-enhancing inputs, manage risks associated with weather and market fluctuations, and access new markets for their products (wiggins, keats, & han, 2016). factors such as lack of collateral, low financial literacy, and the absence of a credit history further exacerbate these challenges (banerjee & duflo, 2011; beck, demirgüçkunt, & martinez peria, 2007). additionally, the high transaction costs associated with serving smallholder farmers in remote rural areas often discourage formal financial institutions from extending their services to this population (gash & odell, 2013). this results in a significant proportion of smallholder farmers relying on informal sources of finance, such as borrowing from friends, family, or moneylenders, which often entail high interest rates and limited protection mechanisms (hermes & lensink, 2007; guérin, labie, & servet, 2015). the promotion of financial inclusion for smallholder farmers has thus become a significant policy objective for governments, development organizations, and the private sector (un, 2015; g20, 2017). numerous studies have demonstrated the potential benefits of financial inclusion for smallholder farmers, including increased investment in agricultural inputs, improved productivity, higher income levels, and reduced vulnerability to shocks (kaboski & townsend, 2011; karlan, osei, osei-akoto, & udry, 2014). as such, understanding the barriers to financial inclusion faced by smallholder farmers and identifying effective strategies to overcome these obstacles is crucial for promoting sustainable development and poverty reduction in rural areas (brune et al., 2016; awotide, karimov, & diagne, 2016). global sustainability research global scientific research 62 fintech solutions for financial inclusion the emergence of financial technology (fintech) has opened new avenues for promoting financial inclusion among smallholder farmers and other underserved communities (alliance for financial inclusion, 2016). fintech solutions such as digital payments, mobile banking, and peer-to-peer lending platforms have demonstrated the potential to increase access to financial services and improve financial management for marginalized populations (buku & meredith, 2018). these innovative solutions also address barriers related to physical distance, cost, and complex documentation, which are often cited as reasons for financial exclusion (demirgüç-kunt et al., 2018). trust and transparency in fintech solutions the success of fintech solutions in promoting financial inclusion largely depends on their ability to foster trust and transparency among users (m-pesa, 2020). trust is a critical factor in the adoption and usage of digital financial services, particularly for individuals who have limited experience with formal financial institutions (buku & meredith, 2018). transparency, on the other hand, is essential for building confidence in these services and ensuring that they adhere to regulatory requirements and consumer protection standards (alliance for financial inclusion, 2016). collaboration between fintech and agriculture sectors the integration of fintech solutions into the agriculture sector necessitates increased collaboration between the two sectors to develop innovative and context-specific solutions (fao, 2017). this collaboration can lead to the development of tailored products and services that address the unique financial needs of smallholder farmers, such as weather-based insurance, digital credit services, and market linkages (world bank, 2019). such targeted solutions can contribute to greater financial inclusion, enabling smallholder farmers to enhance their productivity, manage risks, and access new markets (unctad, 2018). the literature highlights the potential of fintech solutions to promote financial inclusion for smallholder farmers in developing countries like pakistan. the integration of digital platforms for loans, payments, and market linkages can provide farmers with increased access to finance and other financial services. trust and transparency are key factors in the success and sustainability of these solutions, and greater collaboration between the fintech and agriculture sectors is necessary to develop innovative solutions tailored to the specific needs of smallholder farmers. the present study is structured into distinct sections aimed at facilitating a systematic exploration of financial inclusion within the agricultural sector. the introduction section demonstrates an overview of financial technology, emphasizing its critical role in strengthening the agricultural ecosystem in pakistan. the methodology section delineates the research design employed, which involved a meticulous selection of relevant thematic literature review documents. the results section presents the outcomes obtained from comprehensive data analysis conducted within the framework of this research endeavor. lastly, the conclusion section provides a concise summary of the key findings and their implications. additionally, the study acknowledges its limitations and proposes recommendations for future research endeavors. methodology a systematic literature review is a “rigorous, explicit, and transparent method”. for the current study, a thematic literature review was employed. in a thematic literature review, the writer arranges and analyzes previously published research studies in accordance with themes or conceptual frameworks that, in the writer's view, are crucial to comprehending the subject. for the current study, three themes were established to structure the literature review i.e. access to financial technology, awareness of financial technology, and financial support. to conduct the comprehensive review, a targeted selection of keywords was utilized to develop an outline for the collection of relevant publications that formed the basis of the present review. prominent scholarly databases, including google scholar, crossref, and scopus, were employed as primary resource engines. consequently, this thematic systematic review encompasses the entirety of the data identified through a meticulous search across the aforementioned databases. these databases were chosen due to their extensive coverage of findings derived from the initial scoping search. by employing the specified keywords, all publications incorporating finance, financial inclusion, agriculture, smallholder farmers, agriculture in pakistan, and fintech-agriculture in the abstracts, titles, and keywords were identified. global sustainability research global scientific research 63 to ascertain the inclusion or exclusion of studies in the final dataset, a thorough examination of the abstracts was conducted, and in cases where categorization was uncertain, the entire texts were scrutinized. the primary criterion for inclusion or exclusion was the presence of a clear connection between agriculture and finance. this evaluation enabled the identification of a substantial volume of pertinent research; however, it necessitated the exclusion of some significant and captivating research publications. notably, certain previously identified relevant results from a preliminary scoping search were deemed hesitant for incorporation due to the lack of transparency in its search mechanism, thus hindering easy replication. table:1 s. no title of research paper author (s) year key findings access to financial technology 1. role of ict & fintech in

(2024). however, changes in the rain cycle and ecosystems badly affected indigenous communities in different parts of the world including in the hindu kush region of northern pakistan,abate & kronk (2013). indigenous people historically faced the worst policies of the british colonial regime in this region, ksenofontov, s. s., & petrov, a. n. (2024). along with other indigenous communities in this region, the pashtun pastoral community (details are given below) in south asia remained the colony of the british and faced their worst exploitative policies,yousaf (2019). in the postcolonial times, pakistan continued the policies of its predecessor and exploited its natural resources such as mines and minerals which further `reinforced poverty in this region. the british in the colonial era adopted different administrative policies and presented them to the outside world as wild and uncivilized people. global sustainability research global scientific research 18 colonial history and pakistan's exploitative policies in this region make these pastoral communities more vulnerable to climate change. along with colonial history, the soviet-afghan war, and the war on terror in this region intersect their vulnerability to climate change. hence, this research article explores the climate change impact on the pashtun pastoral community. the article also explores the pashtun pastoral community's traditionally entrenched indigenous knowledge, and community institutional role in strengthening their resilience to climate change. this study also focuses on how climate change intersects the pashtun marginality to climate change. pashtun pastoral community and their way of living pashtun pastoral communities live in afghanistan and also inside pakistan,kreutzmann, h., (2000). they live in baluchistan, khyber pakhtunkhwa provinces, and in recently merged districts (previously called the federal administer tribal areas (fata) inside pakistan,khan, & ahmed (2013). in the northern pakhtunkhwa province of pakistan, pashtun's indigenous pastoral community live in mountainous and difficult terrain,(pelevin, (2021). forest, domesticated animals and agriculture are the main sources of livelihood in this region. pashtun pastoral community mainly earn their livelihood from domesticated animals or agriculture. pashtun indigenous pastoral people are farmers or herdsmen, or combinations of both. agriculture, primarily farming, and animal husbandry are the most important economic activities of pashtun pastoral communities. the most common sources of livelihood in this region are agriculture, trade, minerals, and domesticated animals,phillips, c. j. (2024). in addition to raising stock, the pashtun pastoral community as well as some farmers engage in the trade of local indigenous products,advocate & sajid (2013). pashtun pastoral community live in a geographical location which connects central asia with the east and west. historically, and also in the recent past many foreigners such as cyrus, darius, genghis khan, and kushan, and also the british invaded this region in different epochs to achieve their own political goals. they used this region for trade between china, western asia, and europe. gandhari (present-day pakistan) used this region to connect the city of taxila with afghanistan. however, the pashtun region was invaded by many foreigners but the british ruled this region for decades. the british imposed different policies in this region as compared to settled parts of the sub-continent. british in 1849 came into direct contact with the pashtun tribal people. initially, the british adopted the policy of non-interference policy to avoid pashtun indigenous resistance. however, later on, viceroy lansdowne and elgin (between 1887 and 1898), replaced the policy of non-interference with the ‘forward policy’. the forward policy of the colonial regime was resisted by the indigenous tribal pashtun because of its exploitative nature. however, the british exploitative policies in this region significantly distorted their culture and exploited their natural resources in this region,nichols 2010; khan 2020; tripodi (2016). pakistan continued the same colonial policy in this region in post post-colonial period. british and pakistan ignored economic development, therefore, they migrated to different countries such as the united states, europe, and the middle east in search of livelihood. the migrated pastoral pashtun community earns livelihood for the remaining family members who live in native towns. they are also internally migrated to urban centres of pakistan such as karachi, lahore, and islamabad, and to other countries in search of livelihood. however, in the middle east and also in pakistan majority of migrated pashtun are doing hard jobs because the ruling states british and pakistan exploited their resources but they did not extend formal educational institutions to their homeland. in post post-colonial era, the pashtun pastoral community has been facing security problems in this region. in the last four decades, this region has faced many conflicts which significantly affected their livelihood resources,khan (2012). along with violence, and wars in this region, climate change also affected global sustainability research global scientific research 19 pashtun indigenous pastoral communities. climate change also fuels local disputes over natural resources but the state's least interest in their problems makes these pastoral communities self-reliant on their local resources. as mentioned above, pashtun's land is full of natural resources but their resources were exploited by the british in colonial and also by pakistan in the post-colonial era. the federal government of pakistan also exploited the natural resources of the pashtun pastoral community and continued the british exploitative policy in this region. moreover, changing socio-cultural dynamics, globalization and climate change created numerous challenges to these communities. however, they try to face these hardships created by geo-political conflicts and climate change with the help of their indigenous knowledge and socio-cultural institutions. theoretical framework this research article focuses on the impact of climate change on pastoral communities and how they respond to climate change. the indigenous standpoint theory allows researchers to adopt a subjective lens for conducting research,nakata (2007). this theory emphasises the cultural knowledge and experiences of indigenous scholars. indigenous standpoint theory produces more in-depth, culturally inclusive knowledge,nakata,(2007). the indigenous standpoint theory allows us to focus on the cultural interface, and indigenous agency for understanding the responses of indigenous people towards climate change. hence, the indigenous standpoint theory provides theoretical insight into this study while this research article focuses on the traditions, indigenous knowledge, and resilience of the pashtun pastoral community to climate change. methodology this study follows the methodological rules and technicality required to ensure reliability and validity. keeping in view the nature of this research and expected data, the qualitative paradigm was adopted for the completion of this study. the purposive sampling technique was used to collect data from the relevant people who are suffering due to climate change and face natural disasters in their native towns. the data was collected from both men and women of the pastoral community. i conducted 6 months of fieldwork and identified different pastoral communities in northern khyber pakhtunkhwa. the data was collected through in-depth interviews to draw a clear picture of the research problem. themes are carefully derived from the primary data and juxtaposed with the broader literature. indigenous knowledge role in pashtun pastoral community resilience to climate change climate change poses critical implications for indigenous cultures and livelihoods, including the transfer and use of traditional knowledge (tk), also known as indigenous knowledge (ik) rehman, ahmad, & khan, (2021). certain elements of traditional knowledge that are threatened by climate change may include, but are not limited to: weather and climate indicators (ability to predict weather or seasonal forecasts) and ways of learning. climate change affects plants, herbs, biodiversity, and grazing land of animals in this region,khurshid, m., mohammad, n. and somuncu, m., (2017). intergenerational knowledge transfers can be disrupted by climate change in the event of an extreme or emergency, such as floods, fires, droughts, etc. that result in relocation, evacuation, or death of community members. the unpredictable change in weather change causes damage to the socio-cultural fabrics and it displaces the local community from their native town in this region,rahman, ullah, ali, aziz, alam, sher, & ali, (2022). moreover, indigenous knowledge is embedded in the local culture and history of indigenous communities,přívara, & přívarová (2019). pashtun indigenous knowledge is entrenched in their culture, social structure, and traditions. indigenous knowledge evolves in light of their experiences with the local environment global sustainability research global scientific research 20 and climate,ullah, nafees, khurshid, & nihei, (2019). they depend on indigenous knowledge in times of climate change-induced disaster. indigenous knowledge enables them to face the worst impact of climate change (khan, & shah, (2021). in this regard, one of the elder community members stated that “we collectively come together before the beginning of monsoon season and clean the pathways of water. it is based on our indigenous knowledge to evacuate the pathways and prepare and alert our community members about the monsoon season” gul (individual interview, 23 sep 2023). indigenous communities support each other and give collective responses to natural disasters based on their indigenous knowledge. the pashtun indigenous community preserves their indigenous knowledge they take protective measures in the light of their indigenous knowledge (ullah, nihei, nafees, zaman, & ali 2018). they store food for their animal before extreme winter and they predict the extreme weather based on indigenous knowledge. pashtun pastoral communities have limited financial resources and are also ill-equipped to deal with emergencies (such as flooding or forest fires),bayer, (2017). pashtun pastoral communities live in the mountainous region and they are at an even greater risk because external emergency responders may be too far to mitigate the impacts of dangerous situations. winter season or monsoon rains damage their routes and grazing land. it also impacts the delivery of supplies like fruits to markets, timbers for buildings, and gasoline for vehicles. they made their roads with the help of their communities. however, they take protective measures in the light of their indigenous knowledge to protect themselves in extreme weather. women of the pashtun pastoral community store grass for domesticated animals especially for the winter season. in this regard, one of the elder female community members stated that “we made these roads with the help of our pastoral community and women also take part in community work to protect our animals and houses from flooding and heavy rain. we collectively came to build a route for our animals and try to avoid those routes which have a risk of land sliding”. gul bibi (individual interview, 29 august 2023). this indigenous knowledge is transmitted to the young generation from their ancestors,rahman, s.u., ullah, z., ali, a., ahmad, m., sher, h., shinwari, z.k. and nazir, a., (2022). through indigenous knowledge, they protect themselves and animals from landslides and extreme weather. pashtun pastoral people have enough knowledge about the land sliding vanues and other environmental hazardsalmedom, brensinger, & adam,(2016). they have enough experience to protect themselves from local environmental hazards. moreover, they cultivate crops which are resilient to the local environment because climate change has also badly affected the local crops. in this regard, one of the community members stated that “our people know about the local weather conditions and cultivate those plants and crops which are resilient. they learn it from their ancestors. we know about the flood season and we try to avoid routes of land sliding” gul (individual interview, 25 july, 2023). their culturally embedded indigenous knowledge guides them in agriculture activities and also in domesticated animals. they used their indigenous plants for the treatment of animals and also used these medicines for human treatment as well,gioli, khan & scheffran,(2013). these plants are also affected due to climate change and they use their indigenous knowledge to protect these culturally and spiritually valuable plants (islam, tamanna, noman, siemens, islam, & islam, (2022). moreover, climate change affects the natural resources. the scarcity of resources due to climate change fuels conflicts among the local populations especially over grazing land and scarcity of water,lieven. (2020). they used their indigenous knowledge to protect global sustainability research global scientific research 21 grazing land and store water for themselves. their indigenous knowledge evolves in the light of their local experiences. pastoral communities are vulnerable across the world to the impacts of climate change because of their close dependency on and connection with the natural environment for their culture, health, indigenous knowledge and livelihoods,matthew, halle, & switzer, (eds.). (2002). pashtun pastoral community has an emotional attachment to their land and their indigenous knowledge is connected with their natural environment. however, ignoring their indigenous knowledge of climate policy intersects with the pashtun pastoral community's marginality to climate change,ashraf, (2018). their voices are missing in the policy of mitigating climate change's worst impact on their natural resources. the community member stated that “historically and also in the present time state policies ignore the vices of local people and demeaned indigenous knowledge. they presented us as an uncivilized people and do not make policy to utilize our indigenous knowledge for mitigating climate change” hina (individual interview, 25 sep 2023). the government of pakistan has failed to initiate effective policies based on indigenous knowledge to counter the worst impact of climate change on the pashtun pastoral community. the state policies do not properly address their problems and they seek solutions through their cultural institutions by utilizing indigenous knowledge,rahman, s.u., ullah, z., ali, a., aziz, m.a., alam, n., sher, h. and ali, i., (2022). these institutions have the potential to make them resilient to climate change. socio-cultural institutions role in pashtun pastoral community resilience to climate change as mentioned above, climate change impacts indigenous communities across the world. rains have decreased by 40% in the country, and the world food programme classifies both rainfall-related drought and snowmeltrelated drought (owing to the same warming conditions in the hindu kush mountains affecting pakistan to the same effect) as current threats,caney, (2015). pashtun indigenous pastoral communities are more likely to experience the adverse effects of climate change in several ways: having their diets altered as a result of changing ecosystems and demographic changes; affecting the pathways of transportation; their cultural ways of life; and, their abilities to access essential resources and services such as clean drinking water, grazing land for domesticated animals,norton-smith, lynn, chief, cozzetto, donatuto, redsteer, & whyte, (2016). however, they face these challenges alone and the state does not provide any financial support to the pashtun indigenous pastoral communities to face the adverse effects of climate change,glatzer, b., (2021). they rely on their sociocultural institutions in the absence of effective state institutions. in this regard, one of the pastoral community members of pashtun society states that “changes in the rain cycle affect grazing land; we face problems in finding pasturage or our domesticated animals. some of our pastoral people who are dependent on domesticated animals left this profession. however, we culturally support those who cannot economically survive due to climate change” kochay, (individual interview 9 sep 2023). pashtun pastoral communities live in joint or extended families, and they must help each other ,kreutzmann, h. and schütte, s., (2011). they collectively provide psychosocial support to each other in troublesome times ,tainter, & macgregor, (2011). pashtun tribal values reinforce this collectivist structure and discourage individual liberty. it is the responsibility of everyone in the family to economically support all members of the joint or extended family. they also support people outside the family or close kin, especially in times of need ,alam (2021). expectations of reciprocity go beyond psycho-social and financial support. they also support global sustainability research global scientific research 22 each other during disasters based on tribal loyalties. it causes social humiliation for them when they do not support members of their tribe. one of the young adult community members stated that “my home was destroyed in the recent monsoon flood and i do not receive any financial support from the government and my all relatives supported me and i built one room for my children” gul (individual interview, 11 sep 2023). reciprocity, a major cultural value sustains them in times of socio-economic crisis. for this reason, despite being abandoned by the state, they are relying on their social structure. mutual aid is essential after natural disasters to make bridges or supply lines. individuals do not have sufficient resources to bear the financial burden that arises after climate change so they pool their resources. they give food, money, or cattle to each other to face the worst impact of climate change,bustamante, ramos, jacoba, la penia, & gabriel,(2022). reciprocity buffers economic vulnerabilities. it also helps them psychologically because they can face difficult situations with the collective support of their community. at the time of disasters such as floods due to climate change, they support each other. it is the responsibility of the elder women and men in every household to reciprocate when they receive gifts or money in difficult times from other families. they are socially bound by reciprocity and elder women try to remember the families from whom they got help. it is not necessary to return what they received, but they incur an obligation. they may support each other in any form, but they are bound to offer support in times of crisis. climate change and temperature increases directly affect the livestock of the pastoral community,kimaro, e.g., mor, s.m. and toribio, j.a.l., (2018). harsh weather causes diseases in goats and sheep. these pastoral communities are dependent on agriculture or domesticated animals. some of them are seasonally migrated from the northern mountainous region to the lowlands in the winter seasons. climate change affects the migration pattern, especially of the pastoral pashtun community who are dependent on the domesticated animal. the farmers do not have advanced farming technology to face the adverse effects of climate change. they work collectively in fields to assist each other in farming (steele 2020). in pashtun culture, the concept of ashar (collective work) emphasizes mutuality, especially in the time of harvesting, building houses, and collective community work ,mohyuddin, & khan, (2015). the entire community spares one person from each family to help another community member harvest crops or build a house. climate change affects their houses and roads and they collectively work to build those pathways for local transportation. the community member stated that; “the recent flood affected our roads and we all community collectively work on building it again without state help” arshad (individual interview, 25 sep 2023). they also come together to work collectively in times of natural or man-made disasters. ashar gives them the strength to survive in difficult situations and is also a coping mechanism to deal with all kinds of adverse situations that occur due to climate change,raziq, a., tareen, a.m. and verdier, k.d., (2011). for example, the pashtun pastoral community works together to solve water shortages that often occur because of global warming or a shortage of rainfall. they work collectively to build bridges after the flood. the seasonally migrated pashtun or other indigenous groups come together and start a journey towards low land and they come together to face hard situations on the way to low land. climate change affects the grazing land and they face problems in getting pasture for their animals,abdullah, khan, pieroni, haq, haq, ahmad, & abd_allah 2021; hartung,(2017). the scarcity of water and grazing land more often than not causes conflicts among the pashtun pastoral community,muhammad, k., mohammad, n., abdullah, k., mehmet, s., ashfaq, a.k. and wajid, r., (2019). the pashtun cultural institutions jirga often resolve their conflicts and make them resilient to face the worst impact of climate change. global sustainability research global scientific research 23 climate change interface pashtun pastoral community marginality pastoral communities’ vulnerability varies and is affected by interacting and complex historical, political, and social factors, such as differential access to resources, poverty, and different ways of accessing,ali, (\2022). the existing historical context of colonial trauma, discrimination, neglect, and pakistan's exploitative policies collectively intersect with pashtun's marginality to climate change ,ingalls, & mansfield, (2017): (lieven 2023). pashtun pastoral communities have experienced the impact of climate change and it has directly affected their socio-cultural values. proverbs, literature, and social movements all reflect and reinforce pashtun's resilience in culturally grounded ways. their sociocultural values, social organization, and indigenous knowledge collectively help them to face the worst impact of climate change in the absence of welfare policies of the state. conclusion this research essay focuses on the pashtun pastoral community's resilience to climate change. it is revealed that pashtun socio-cultural capital strengthens the indigenous resilience of pashtun pastoral people to face the adverse effects of climate change. strong social bonds and kinship ties unite them to face difficult situations that arise due to climate change. this research uses examples grounded in a masculine worldview of the pashtun pastoral community. however, their women face significant adversity and have the additional challenge of depending on their male family members due to climate change. it is also important that a focus on resilience not downplay significant, ongoing challenges. indeed, the dependence of pashtun people on their societal institutions could make them reluctant to develop more advanced, formal institutions to counter climate change. activities that work to restore relations with the land, waters, and living world are necessary to restore balance in social systems (adaptation planning is one type of actionable science that is improved through the use of locally relevant information derived from traditional knowledge. hence, indigenous knowledge and local sociocultural institutions play a vital role in strengthening pastoral community resilience to climate change. declaration acknowledgment: none funding: no funding conflict of interest: none authors contribution: sole author data availability: this is not applicable in my research article references asian countries: a critical review. india ii: climate change impacts, mitigation and adaptation in developing countries, 1-32s abate, r. s., & kronk, e. a. 2013. the commonality among unique indigenous communities: an introduction to climate change and its impacts on indigenous peoples. tulane environmental law journal, 179-195. ashraf, s. i. 2018. journalism at ground zero: imperial wars and precarious labor in frontline news production in pakistan. southern illinois university at carbondale. global sustainability research global scientific research 24 ali, s. 2022. hegemony, marginalisation, and hierarchies: masculinities in contemporary pakistani anglophone fiction (doctoral dissertation, the university of waikato) abdullah, a., khan, s. m., pieroni, a., haq, a., haq, z. u., ahmad, z., ... & abd_allah, e. f.

published: 29 august, 2024 abstract this research work examined the impact of tourism industry on poverty eradication in southern nigeria. tourism industry refers to the economic sector that encompasses various activities related to the travel and leisure of people to destinations outside their usual environment. the objective of the study investigated the effect of restaurants establishment on job creation and effect of tourist attractions on increased health care, problem of study include lack of comprehensive data, unequal distribution of benefits, inadequate infrastructure, environmental sustainability, and limited capacity building opportunities all pose significant challenges to achieving poverty reduction through tourism. the tourism industry has the potential to stimulate economic activities in various sectors such as hospitality, transportation, arts and crafts, and cultural heritage, thus providing multiple avenues for poverty reduction. the researchers made use of survey research method, where 150 questionnaires was administered to staffs and tourists at the chosen attractions. data was analyzed descriptively using frequency distribution tables and simple percentage in order of research question. the researchers also tested hypotheses using chisquare statistical techniques. from the researcher's findings, the study revealed that tourism industry such as restaurants establishments , tourists attractions has significant positive impact on poverty eradication in southern nigeria. this research concludes that balancing economic gains with social and environmental responsibility is essential for maximizing the positive impact of tourism on poverty eradication. the researchers recommends that governments, businesses, and communities should collaborate to create policies that prioritize social and environmental responsibility while harnessing the economic potential of tourism for poverty alleviation, and also investing in education and skills development for local communities can enhance their capacity to participate in and benefit from the tourism sector. keywords: tourism; tourism industry; poverty; eradication; poverty eradication. introduction. tourism industry, also known as the travel industry, is linked to people traveling to other locations, either domestically or internationally, for leisure, social, or business purposes (aturu 2022). it is closely connected to the hotel industry, and the transport industry. much of it are based on keeping tourists happy, occupied, and equipped with the things they need during their time away from home. the tourism industry is one of the world’s largest industries, and the economies of many nations are driven, to a large extent, by their tourist trade. the tourism industry is also a wide-range industry, which includes the hotel industry, the transport industry, and several additional industries or sectors. global sustainability research global scientific research 16 the tourism industry includes hospitality (e.g. accommodation, restaurants), transportation (e.g., airlines, car rental), travel facilitation and information (e.g., tour operators, travel agents, tourist information centers), and attractions and entertainment (e.g., heritage sites and theme, national, and wildlife parks( ilo2022). poverty eradication refers to the collective efforts and strategies aimed at eliminating or substantially reducing poverty in a particular region, country, or the world as a whole. it is a multi-dimensional concept that goes by beyond just increasing income levels and encompasses various aspects of human well-being. the goal of poverty eradication is to ensure that all individuals have access to the necessary resources, opportunities, and capabilities to lead a life of dignity and achieve their full potential. poverty eradication is a complex and long term endeavor that requires coordinated efforts from governments, civil society organizations, the private sector, and international institutions. the tourism industry has emerged as a potential avenue for poverty eradication and sustainable economic growth in lagos state. it has the potential to stimulate economic activities in various sectors such as hospitality, transportation, arts and crafts, and cultural heritage, thus providing multiple avenues for poverty reduction. in nigeria, the traditional approach to poverty reduction has largely been direct, in terms of interventions related to basis empowerment of the poor, primarily through the skill-credit-subsidy route. the primary aim of this research work investigated the contribution of tourism industry on poverty eradication by creating jobs, boosting local incomes, and stimulating economic growth in the regions it operates, thereby lifting people out of poverty and improving their living standards.these was achieved during our regorous research in southern nigeria. statement of problem ladan (2022) suggested that lack of comprehensive data, unequal distribution of benefits, inadequate infrastructure, environmental sustainability, and limited capacity building opportunities all pose significant challenges to achieving poverty reduction through tourism. addressing these problems requires a coordinated effort from various stakeholders to promote inclusive and sustainable tourism practices that prioritize poverty eradication. this research is geared towards addressing the role of tourism industry in poverty eradication in southern nigeria. objective of study the general objective of this study examined the impact of tourism industry on poverty eradication in southern nigeria. but the specific objectives investigated the effect of restaurants establishment on job creation and effect of tourist attractions on increased health care density. research questions 1. what is the effect of restaurants establishment on job creation? 2. what is the impact of tourist attractions on increased health care density? research hypotheses. null hypotheses : 1. there is no significance positive relationship between restaurants establishment and job creation in selected hotels and restaurants in southern nigeria. 2. there is no significance positive relationship between tourist attractions and increased healthcare density in selected hotels and restaurants in southern nigeria. global sustainability research global scientific research 17 significance of study this research work will help to examine the impact of tourism industry on poverty eradication within our environment in southern nigeria.it shed light on its sustainability and how it can be harnessed to minimize negative effects on the environment while maximizing positive socioeconomic outcomes and which tourism can empower local communities also by promoting cultural heritage, fostering entrepreneurship, and supporting local artisans and businesses. economic development will benefit by understanding how tourism affects poverty level can help identify opportunities to stimulate economic growth and create job opportunities for locals. tourism revenue can contribute to improving infrastructure, education, and healthcare, potentially lifting people out of poverty. investors and businesses will benefit when they use the study’s insights to make informed decisions about investing in the tourism sector, potentially contributing to poverty reduction through job creation and income generation. this study can add to the body of knowledge on tourism’s role in poverty reduction. it will benefit researchers and policymakers beyond lagos state and potentially influencing international development strategies. review of related literature tourism tourism is travel for pleasure or business, and the commercial activity of providing and supporting such travel. the world tourism organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". tourism can be domestic (within the traveler’s own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments(ilo 2022). types of tourism : some kinds of tourism are explain below: business tourism: this type of tourism involves traveling to different locations to attend business issues or work. in business tourism, individuals still work according to their regular schedule, but the difference is that they are doing it away from their typical workplaces. example of activities that happen in business travel include attending seminars, trade fairs, meetings , conferencesthat kind of thing, business tourism doesn’t involve booking into hotel and eating and spending money in the local community. food tourism: speaking of buffetsare there anyone who doesn’t love good food? many tourists simply follow their taste buds and choose their holiday destinations based on the things they want to eat. popular destinations for food tourism include italy, spain, france, and japan and if you’re in anyone of these destinations or a particular location that’s known for nice food that i haven’t named just make sure your marketing includes a picture of whatever’s local and delicious. it’s what i call “a delicious type of tourism. so in this research the researcher regards those who travel out of their environment just to eat different type of food that they aren't familiar. https://en.wikipedia.org/wiki/travel https://en.wikipedia.org/wiki/world_tourism_organization https://en.wikipedia.org/wiki/leisure https://en.wikipedia.org/wiki/domestic_tourism https://en.wikipedia.org/wiki/international_tourism global sustainability research global scientific research 18 sport tourism: sport tourism is a type of tourism that involves attending sporting events or participating in sports activities. as hotelier, sports tourism presents an opportunity to attract a specific kind of traveller and to increase occupancy during periods of high demand. sports events, such as marathons, golf tournaments, and international sporting competitions, can draw large numbers of visitors to a destination. these travelers often require accommodations, making hotels a key part of the sports tourism industry (ogbemudia 2018). wildlife tourism: wildlife tourism is a growing industry that involves traveling to natural areas to observe and interact with wildlife. this can include activities such as birdwatching, whale watching, and safaris. hotels located near national parks or other protected areas can also benefit from wildlife tourism, as these areas are often home to a wide variety of animals that tourists may want to see. (da silva 2017). religious tourism: religious tourism is a type of tourism that involves visiting religious sites and participating in religious activities. this can include traveling to places of worship , such as churches, temples, mosques, as well as participating in religious festivals and pilgrimages. religious pular all around the world, and many people engage in this type of travel for a variety of reasons. some people travel for religious reasons, such as to participate or to visit a holy site. others may be interested in learning more about different religions and the role they play in different cultures. country side tourism: this type of tourism isn’t as rooted in tours and tourist attractions so much as others. it is more concerned with the visitor’s experience. it’s about escaping from one’s usual environment and experiencing life as other people live it, away from the noise of the hoi polloi. oftentimes, countryside tourism is about experiencing an event as opposed to seeing some great thing or exploring some particular environment( awoseyin 2017). components of tourism these components work together to create the tourism industry, providing a wide range of experiences for travelers and contributing to the economies of many regions worldwide.tourist attractions: these are the destinations and places that attract tourists , such as natural landmarks, cultural sites, historical monuments, theme parks and more. accommodation: accommodation options include hotels, resorts, hostels, vacation rentals, campgrounds, and other places where tourists stay during their visits. transportation: this encompasses the various modes of transportation that tourists use to reach their destinations, including airlines, trains, buses, cruise ships, and car rentals, food and dining: restaurants, cafes, street food vendors, and local cuisines are integral to the overall tourism experience .tour operators and travel agencies: these businesses assist tourists in planning and booking their trips, offering packages, guided tours, and travel services.hospitality: the overall service and reception provided to tourists, ensuring a positive and comfortable experience during their stay.. events: special occasions, festivals, or gatherings that are can attract tourists, providing unique experiences tied to the destination’s culture or offerings. safety and security: ensuring the safety and security of tourists is a critical aspect, destinations often have law enforcement and emergency services dedicated to this purpose. (da silva 2020) types of tourism industry. the tourism industry comprises several sectors that work together to facilitate travel and provide services to visitors. these sectors include: global sustainability research global scientific research 19 hospitality: involves accommodation such as hotels, restaurants, resorts, and guesthouse, catering to tourist lodging needs(coltman 2020). transportation: encompasses airlines, cruise lines, railways, buses, and other modes of transport facilitating the movement of tourists. attractions: included tourist destinations, landmarks, theme parks, museums, and other places that draw visitors.travel agencies: assist in trip planning, offering services like booking flights, accommodations, and tours.tour operators: organize and provide guided tours, often including transportation, accommodation, and activities. food and beverage: restaurants, cafes, and local eateries contribute to the overall tourism experience.entertainment: involves events, shows, and nightlife options that enhance tourists recreational opportunities.travel technology: platforms and apps that aid in trip planning, booking, and navigation. impact of tourism industry on poverty eradication: dada(2021) is of opinion that the impact of tourism industry on poverty reduction is a multifaceted topic with both positive and negative dimensions.employment opportunities: tourism can create a direct and indirect employment opportunities, particularly in hospitality, transportation, and related sectors. this contributes to income generation and poverty reduction.income generation: tourism activities can lead to increased income levels for individuals and communities. local businesses, artisans, and service providers benefit from the influx of tourists.entrepreneurship and small businesses: tourism often fosters entrepreneurship and the development of small businesses. locals may establish enterprises catering to tourists , furthering diversifying the economy.infrastructure development: the tourism industry can drive improvements, including transportation, sanitation, and utilities. enhanced infrastructure benefits both tourists and local residents, improving overall living conditions.cultural preservation: tourism can contribute to the preservation of local cultures and traditions. communities may find economic value in maintaining their unique cultural heritage, leading to cultural conservation.community involvement: community based tourism initiatives empower local communities by involving them in decision making processes and ensuring that they directly benefit from tourism activities.negative impacts: environmental degradation: uncontrolled tourism growth can lead to environmental degradation, impacting ecosystems, wildlife, and natural resources. this, in turn, affects local communities that depend on these resources.community commodification: over-commercialization of local culture to cater to tourist demands may lead to the commodification of traditions, potentially diluting their authenticity and significance.inequality and leakage: tourism revenue doesn’t always evenly distribute among local communities. leakage occurs when a significant portion of income leaves the destination due to foreign-owned businesses or imported goods.seasonal employment: in some cases, tourism-related jobs may be seasonal, leading to fluctuations in income for those reliant on the industry. social disruption: rapid tourism development can cause social disruption, impacting local lifestyles, community structures, and social dynamics( goyang 2018). the impact of tourism on poverty eradication can vary depending on factors such as the scale of tourism development, the level of community involvement, and the sustainability of tourism practices. responsible and sustainable tourism planning that considers the needs and aspirations of local communities is essential for maximizing the positive impact on poverty eradication and promoting inclusive growth. it’s crucial to address any negative impacts that tourism may bring, such as environmental degradation, cultural commodification, and social disruptions. effective management and regulation are necessary to ensure that tourism development is balanced and benefits the local population while preserving the destination’s natural and cultural assets. tourism often provides income for local communities through the sales of goods, services, and handicrafts. this income can contribute to poverty reduction by improving the economic of individuals and communities, the demand global sustainability research global scientific research 20 from tourists can drive investments in infrastructure, such as roads, airports, and utilities. improved infrastructure not only benefits tourists but also enhances the overall quality of life for local residents. tourism can stimulate the growth of small businesses, including restaurants, souvenirs shops, and local markets. this can empower entrepreneurs, fostering economic development at grassroots level. types of poverty eradications: poverty eradication involves various approaches aimed at alleviating or eliminating poverty. some of the types of poverty eradication include: economic growth: promoting overall economic development to create jobs and increase opportunities (lewis2019). education: investing in education to enhance skills, knowledge, and employability, breaking the cycle of poverty. social safety nets: establishing social welfare programs, such as cash

offering jobs in various sectors such as hospitality, transportation, retail, and tour operations. these jobs provide income and stable employment for local residents, helping to lift them out of poverty. tourism-related activities generate income for individuals, businesses, and the local government through various channels such as accommodations, dining, entertainment, and transportation. this infusion of income can positively impact the local economy and contribute to poverty alleviation. global sustainability research global scientific research 21 tourism can inspire entrepreneurship, with locals starting their businesses to cater to tourists' needs. these businesses can range from small guesthouses and restaurants to craft shops and tour operators, promoting economic diversification kotler(bowen & makens 2020). improved infrastructure not only enhances the tourist experience but also benefits local residents and communities. to accommodate tourists, destinations often invest in infrastructure development such as transportation networks, roads, airports, and sanitation facilities. tourism can contribute to the development of less-visited regions and rural areas, spreading economic benefits beyond major cities and tourist hotspots. responsible tourism practices that involves and benefit local communities can lead to community development projects, such as schools, healthcare facilities, and clean water initiatives. these projects improve the quality of life for residents and contribute to poverty reduction (ikwu2019). tourism can foster the preservation of cultural heritage and traditions, by valuing and showcasing local culture, communities can leverage their unique identity to attract tourists, generating income and creating a sense of pride. the tourism industry brings in foreign exchange through spending by international tourists. this foreign currency can boost a country’s foreign reserves, which can be used for development projects and economic stability.adejuwon (2019). methodology this research work was limited to nine tourist attractions within the southern nigeria which includes three from south west, three from south east and three from south-south. the questionnaires was randomly distributed to the respondents at the destinations (staff and residents). 150 questionnaires was structured and used to collect information from respondents from each case studies the questionnaire was made brief and simple with the aim of generating the required and relevant information from the respondents concerned. the questionnaire was designed to allow respondents the opportunity to provide useful and varied information of importance to the study. the sample size is the total available elements to select which represent the entire population. in this research the researchers purposively selected a total of 150 respondent's that is 50 in each geopolitical zones that make up the southern nigeria. data collected was analyzed descriptively. the analysis was presented in descriptive form, and illustrated with appendixes in appropriate places. frequency distribution table and simple percentage was used for data presentation. the table of the study was analyzed according to the order of the research questions drawn up from the respondents in the structured questionnaires. in analyzing the data

and job creation. however, second hypothesis revealed that there is significant positive relationship between tourist attractions and increased healthcare density.however this findings are in agreement with smith and johnson (2021) whose research discovered that tourism industry plays a vital role on poverty reduction. conclusion based on the results of the research conducted, the conclusions obtained are that the tourism industry can contribute to infrastructure development. however, there are challenges such as environmental degradation, cultural disruption, and income inequality. the researcher also concluded that balancing economic gains with social and environmental responsibility is essential for maximizing the positive impact of tourism industry on poverty eradication especially in southern nigeria.. recommendations based on the findings of this research, the following recommendations are presented as follows: • implementing sustainable tourism practices, fostering community engagement and empowerment, promoting local entrepreneurship, and ensuring equitable distribution of benefits is recommended by all stakeholders. • governments, businesses, and communities should collaborate to create policies that prioritize social and environmental responsibility while harnessing the economic potential of tourism for poverty alleviation. • lastly, investing in education and skills development for local communities can enhance their capacity to participate in and benefit from the tourism sector. declaration acknowledgment: n/a funding:

philippines corresponding author: alvin q. romualdo, mpsa: aqr031891@gmail.com received: 01 july, 2023, accepted: 28 july, 2023, published: 01 august, 2023 abstract the environment holds a vital position within the framework of sustainable development, serving as the foundation upon which social and economic progress relies. however, its vulnerability and the market failures resulting from its degradation pose significant challenges to achieving sustainability. this study was conducted to gain valuable insights into the present and future performance of police officers concerning their role in advancing environmental sustainability. as a result of the consensus among the experts, a total of thirty (30) forecasted sustainability indicators for green policing were generated. these indicators represent the combined perspectives and agreements of the experts regarding the essential elements and factors involved in the implementation of green policing practices. the indicators are categorized into four themes that emerged from the analysis: green police operations, green behavior and awareness, environmental law enforcement, and community partnerships and engagement. these themes provide a comprehensive framework for guiding and assessing the implementation of green policing initiatives in various contexts. in light of these findings, it is strongly recommended that law enforcement agencies operating in the soccsksargen region integrate these identified sustainability indicators into their green policing strategies and operations. by doing so, they can effectively align their practices with the principles of environmental sustainability and contribute to the overall advancement of green policing initiatives. recognizing the interdependencies and taking concerted actions to address these issues, societies, with the law enforcers as stewards, can pave the way for a more resilient and harmonious relationship with the environment, fostering a sustainable future for generations to come. keywords: green police operations; green behavior and awareness; environmental law enforcement; community partnerships and engagement introduction the environment serves as a fundamental pillar of sustainable development, playing a pivotal role in supporting and influencing the social and economic dimensions. over time, societies have recognized the significance of maintaining a harmonious relationship with the environment to ensure a balanced and sustainable way of life (mensah, 2019). however, the environment faces continuous pressures and threats, making it highly vulnerable and prone to deterioration. in fact, it has become a prominent source of market failures worldwide, as its degradation undermines the well-being of individuals and societies at large. the interdependence between the environment and other dimensions of sustainable development is evident. social and economic progress relies heavily on the availability of natural resources, the functioning of ecosystems, and the stability of ecological processes chapin iii et al., (2009); harris & roach (2013). from providing essential resources and ecosystem services to supporting livelihoods and global sustainability research global scientific research 53 economic activities, the environment acts as a foundation for human well-being and development. nevertheless, the relentless exploitation of natural resources, pollution, habitat destruction, climate change, and other anthropogenic factors have severely impacted the environment. these pressures have led to various market failures, where the true value and costs associated with environmental degradation are not adequately accounted for unepirp, 2011). as a result, society faces adverse consequences, such as resource depletion, biodiversity loss, environmental disasters, health risks, and socioeconomic imbalances. recognizing the fragility and importance of the environment is crucial for addressing these challenges. efforts must be directed towards sustainable practices, policies, and initiatives that aim to conserve and restore the environment while promoting socio-economic well-being. this necessitates a shift in mindset and behavior, as well as the adoption of innovative approaches that embrace the principles of sustainability, including conservation, resource efficiency, pollution prevention, and climate resilience. by acknowledging the integral role of the environment and addressing the market failures associated with its degradation, societies can strive towards a more sustainable future (dean & mcmullen, 2007). this entails promoting responsible consumption and production patterns, investing in renewable energy and green technologies, preserving ecosystems and biodiversity, implementing effective environmental regulations, fostering public awareness and participation, and encouraging collaboration between stakeholders at local, national, and global levels. environmental law enforcement plays a crucial role in driving the pursuit of environmental, social, and economic sustainability. within this context, the public safety sector holds significant responsibility for enforcing environmental laws and policies, thereby contributing to the establishment of green communities. recognizing the importance of this role, the present study aimed to forecast the sustainability indicators of police officers in the field of green policing (konyk, 2018; romualdo 2022). by focusing on green policing, the study sought to understand and predict the extent to which police officers contribute to sustainable practices and outcomes. green policing entails the integration of environmental considerations into law enforcement practices, encompassing initiatives such as promoting environmental awareness, enforcing environmental regulations, fostering community engagement, and implementing sustainable approaches within police operations. through forecasting the green policing sustainability indicators, the study aimed to provide insights into the current and future performance of police officers in terms of their contributions to environmental sustainability. this forecasting process involved analyzing various factors, such as the level of green behavior and awareness among police officers, the degree of environmental law enforcement, the level of community partnership and engagement, and other relevant dimensions identified within the green policing framework. ultimately, the study aimed to contribute to the advancement of green policing as a holistic approach within the public safety sector, integrating environmental considerations into law enforcement practices. by forecasting the sustainability indicators of police officers, the research aimed to provide valuable insights and recommendations to support the ongoing efforts towards creating environmentally, socially, and economically sustainable communities. methodology this study utilized a qualitative research design to gather and analyze data. the research approach involved conducting a thorough literature review to examine existing knowledge and insights on the subject of interest. this review helped establish a foundation for the study and identify key themes, concepts, and theories relevant to the research topic. in addition to the literature review, the study also employed the delphi technique as a panel review method. the delphi technique is a structured communication process that seeks to gather expert opinions and insights on a particular topic. it involves multiple rounds of surveys or questionnaires administered to a panel of experts in the field (hsu, & sandford 2007). through these iterative rounds, the experts provide their perspectives, rate the importance or relevance of specific factors, and share their expert opinions. global sustainability research global scientific research 54 figure 1. delphi processes by zhang et al., (2022) the sustainability indicators related to green policing were forecasted based on a constructed scenario and were subsequently validated through a delphi approach involving a panel of environmental experts. the panel consisted of twelve (12) participants, including five station commanders, two police section chiefs, two coast guard commanders, and three section chiefs from the department of environment and natural resources in soccsksargen. results and discussion in the initial round of data collection, a significant number of item responses were obtained from the selected group of experts, amounting to a total of 109 (figure 2). these responses were carefully transcribed and analyzed to identify key trends and patterns related to green policing. through a process of coding, the responses were organized and categorized based on their relevance to the overarching themes and concepts of green policing. this restructuring of the data was done to ensure coherence and congruency in the analysis and interpretation of the findings. global sustainability research global scientific research 55 figure 2. radar chart of the responses of experts by transcribing and coding the item responses, common themes, recurring patterns, and important insights regarding green policing were determined. this process allowed for a comprehensive understanding of the expert opinions and perspectives on the topic. the large number of item responses generated in the first round of data collection signifies the richness and depth of the experts' input. it demonstrates the thoroughness and comprehensiveness of the study in capturing diverse perspectives and insights related to green policing. during the subsequent round of the study (round 2), the experts were presented with the restructured responses for further review and analysis. the facilitator's objective was to extract more precise and detailed indicators from the experts' initial responses, refining the understanding of the key themes and patterns identified in the data. out of the original 109 responses, a subset of forty-five (45) responses was selected for further examination and consideration. these refined responses would contribute to a more focused and comprehensive understanding of the indicators associated with green policing. through the careful transcription, coding, and restructuring of the responses as seen in figure 3, the researchers were able to extract valuable information and lay the foundation for further analysis and interpretation through codes. 37 21 14 37 station commanders section chiefs coast guard commanders denr department heads global sustainability research global scientific research 56 figure 3. patterns, trends, and indicators in round 2 of delphi after conducting a meticulous examination and comprehensive review of the responses provided by the experts, a total of thirty-five (35) indicators were identified as relevant indicators of green policing. these indicators were carefully transcribed by the researcher and further categorized into distinct themes based on the observed trends and patterns within the data. the resulting themes associated with the indicators are as follows: green police operations, green behavior and awareness, environmental law enforcement, and community partnerships and engagement. this categorization allows for a clearer understanding of the different aspects and dimensions encompassed by the concept of green policing. global sustainability research global scientific research 57 figure 4. themes of sustainable green policing during the final round (round 3), the experts were engaged in a more focused and constructive manner, leading to the generation of concise and succinct responses. this iterative process aimed to involve the experts in the decision-making process, allowing them to actively participate in the analysis and design of the final research instrument. by incorporating the expertise and insights of the experts, the researcher sought to enhance the instrument's effectiveness and relevance. this approach aligns with the principles outlined by keeney et al. (2011), emphasizing the importance of engaging experts in the decision-making process to ensure a comprehensive and well-informed outcome. in the final round, which marked final round, consensus was achieved among the experts. through a process of discussion and deliberation, a state of homogeneity and consistency in their responses was attained, as highlighted by graham et al. (2003). this collective agreement among the experts led to the generation of thirty (30) forecasted sustainability indicators of green policing. these forecasted indicators represent the shared perspectives and expert consensus on the key aspects and considerations of implementing green policing practices (romualdo, 2022). global sustainability research global scientific research 58 figure 5. forecasted sustainability indicators of green policing conclusion and recommendation the findings of this study have identified a comprehensive set of sustainability indicators for green policing in the soccsksargen region. these forecasted indicators reflect the measures and initiatives that police officers can undertake to promote environmental sustainability within their operations and communities. the green policing sustainability indicators encompass various aspects such as resource conservation, waste management, renewable energy utilization, collaboration with stakeholders, environmental law enforcement, and community engagement. based on these findings, it is recommended that law enforcement agencies in the soccsksargen region incorporate these sustainability indicators into their green policing strategies. this can be achieved through the development and implementation of specific policies, guidelines, and training programs that align with the identified indicators. additionally, close collaboration with relevant agencies, organizations, and stakeholders should global sustainability research global scientific research 59 be fostered to ensure the effective implementation of these initiatives. furthermore, regular monitoring and evaluation of the progress made in implementing the sustainability indicators are crucial to assess the effectiveness of green policing efforts. this will help identify areas for improvement, refine strategies, and ensure the long-term sustainability of environmental initiatives within the public safety sector. public awareness campaigns and community engagement activities should also be prioritized to promote a culture of environmental responsibility among both police officers and the wider community. partnerships with organizations such as the philippine coast guard and market organizations can be established to facilitate recycling programs and income-generating activities that contribute to environmental sustainability. by adopting and implementing these sustainability indicators of green policing, police officers in soccsksargen can pave the way for fostering greener and safer communities, thus contributing significantly to forging a sustainable future. acknowledgment. the authors of this research work acknowledge the support and guidance of dr. rec e. eguia, dr. prescillano d. campado, dr. alfie maria r. custodio, dr. jinnifer d. arroyo, and dr. cheryl marie c. cipriano funding. this research receives no grant from any funding agency in the public, private, or not-for-profit sectors. contribution/originality: this research contributes to the breadth of knowledge by providing a forecast of the indicators of environmental sustainability in public safety through a delphi technique. as an outcome of this independent and original work, we duly acknowledge all the sources from which the ideas have been derived. declaration of conflicting interest. the authors declare no conflicts of interest in the development of this research work. availability of data: the authors confirm that the data supporting the findings of this study are available within the article and its supplementary material. raw data that support the findings of this study are available from the corresponding author, upon reasonable request. references chapin iii, f. s., kofinas, g. p., & folke, c.

local government; administration introduction typically, government of nation rotect, provide social facilities and enact policies that lead to better life of citizens of such state. these are achieved through devolution of power to segments of government from federal to state and local government, (imene 2023). the local environmental is a term that is allied with the natural conditions which living things animate. it is connected with the conditions that affects the behaviour and development of environment. it looked at society and its natural environment. environmental analysis (ea) is aligned on evaluation of interactions between living organisms and their natural habitats. global sustainability research global scientific research 44 an environmental analysis is a tactical method that pinpoint all internal & external elements that might have an impact on a public or private organization's success. environmental analysis offers insights into species' evolutionary histories and contemporary factors influencing events. it applies to public management, examining the impact of public organizations on their environment. it examines global policies and their interactions, as the world becomes a global village. political ecology focuses on societal interactions and politics in relation to environmental issues. there are various environmental factors that impede the development of local government administration (lga) in nigeria and other states. environmental factors like hinder the development of local government administration (lga) in nigeria. the primary objective is to improve the federal government's development agenda, and lga's rights are enshrined in the constitution, with reforms tasked with responsibility and financing (imene 2023) environmental analysis of lga in this context is mostly concerned with how the above factors affect the way in which local affairs is conducted and how administrative actions affect the core values of government interaction. ikenga & chima (2021) argued the failure of government to provide visionary leadership, good governance such as transparency, accountability and provision of socioeconomic amenities that have direct bearing on the lives of the people. lga has no universal application rather it has to be analyzed within the ecological attributes of each administrative system in which it operates. environmental analysis is a strategy or a game plan that reflects administrative awareness of how, when and where it should compete, against whom and for what purpose it should compete. it is not only important for all organizations (public or private) to understand why they are in existence but also to put in place an attainable strategic plan to improve their productivity. survival can be traced to efficient use of resources to achieve greater level of performance (erhijakpor& aroghene, 2023). imene and udjo-onovughakpo opined that productivity in most firm has fallen as a result of recurrent conflict within an organization. since survival is related to productivity there is need for administrators of local government administration to harmonise their environmental factors to obtain its optimum objectives. statement of the problem local government administration is often faced with diverse challenges that prevent their attainment of their objectives and optimum performance which include quality primary education, maintenance of local roads, provision of parks, maintaining conducive environment, provision of basic social amenities and proper town planning, alao, etal (2016) sated that the government at the local level equally carries out the task of naming roads and streets and numbering of houses; provision of maintenance of public amenities, sewage, and garbage collection; certification of all births, deaths, and marriages; valuation of privately held homes or tenements for the intent of placing rates as may be authorized by the house of assembly of a state among other things. the establishment, maintenance, and control of slaughterhouses, marketplaces, motor parks, street lights, drainages, and other public roadways, are all tasks that fall under the purview of local government administration. the challenges that impede lga from attaining optimum objectives as stated by some scholars are in diverse areas including deprived autonomy, access to information, access to credit facilities and finances, poor skills matrix, lack of skills required to survive with populace demands, economic linkages, and lack of access to development services that are critical for their productivity. local government council area often have low education levels, poor management styles of their enterprises, lack of awareness on the strategic management practices, challenges in acquisition of external financial support and challenges in strategic management of sources of finance. a failure to understand and analysed the environmental components of a local government council could be seen as a debacle for non-attainment of local government objectives in most developing countries such as nigeria. these challenges when not addressed, lead to a high level of collapse of the productivity and essence of creating global sustainability research global scientific research 45 local government as a tier of government. a number of studies such as joseph a, s (2014), alao, etal (2016), mukoro a., asaju, k. (2010) ikenga & chima (2021) and imene a. (2023) have been carried out on under performance of lga in nigeria and other developing countries but a minimal focus on environmental analysis of lga was discovered. it is based on this premise that this study tends to look at the effect of environmental analysis that comprises political analysis, social analysis, economic analysis, legal analysis (pesl) of lga in developing states with the view of seeing how this can help in attaining its optimum objectives. thus, the aim of this study is to fill the gap by providing more evidence on strategic management processes through environmental analysis of lga in nigeria. the major tools the study employed is pesl to form the environmental analysis of local government administration in developing states to actualize their optimum goals. study objective the general objective of the study is to examine the effect of environmental analysis and optimal attainment of local government administration (lga) objectives in developing states while the specific objectives are as to: 1. examine the effect of political environmental analysis on optimal attainment of lga objectives in developing countries 2. examine the effect of economic environmental analysis on optimal attainment of lga objectives in developing countries 3. examine the effect of social environmental analysis on optimal attainment lga objectives in developing countries 4. examine the effect of legal environmental analysis on optimal attainment of lga objectives in developing countries research hypotheses no significant relationship exists between: 1. political environmental analysis and optimal attainment of lga objectives in nigeria. 2. economic environmental analysis and optimal attainment of lga objective in nigeria. 3. social environmental analysis and optimal attainment of lga inistration objective in nigeria 4. legal environmental analysis and optimal attainment of lga objective in nigeria. scope of study the study covers local

of environmental analysis environmental analysis is a crucial step in strategy formulation, involving a thorough analysis of both internal and external environments. it helps identify opportunities and threats, while internal analysis focuses on identifying distinctive competencies. muriuki, etal (2017) this analysis includes pestle, porter's 5 forces, and internal resources, ensuring a comprehensive understanding of an organization's operations. environmental analysis is a process that identifies and addresses issues through internal and external assessments. it involves swot analysis, focusing on opportunities and threats, and internal capacity. environmental scanning is a process that monitors the business environment to make informed decisions. it helps administrators understand global sustainability research global scientific research 47 changes in economic, political, social, and technological trends, enabling governments to respond appropriately and meet their objectives. conceptualization of local government administration (lga) lga do not have a static definition but are seen from different scholars point of view. the 1976 lg reform guidelines definef lg of given in the recommendations is "government at the local level carried out by representative councils established by law to carry out specific functions within the defined boundaries." (frn 1976). the lg is "open-access field institutions at the most basic sub-national level of government, formally and legally acknowledged, and required to carry out certain functions at the community level." awa claims that lg is a political organization whose goal is to disperse political power. 1976). lg is defined by iyoha, etal. (2005) as the ability of local residents to solve their own issues. they went on to say that the lg is a body made up of the local population who manage grassroots issues. adamolekun (1983) defined local government as the bureaucracy responsible for organizing, planning, and directing the management of specific affairs. emezi (1984) defines local government as a structured system aimed at preserving law and order, providing social facilities, and encouraging collaboration among residents for improved living conditions. imene (2023) defines local government (lg) as a political and administrative institution managing grassroots affairs, requiring political clout and authority, and specific skills for various activities. lg, a separate legal entity from state and federal governments, is authorized to plan, design, and implement local programs, initiatives, and rules. environmental analysis (ea) tools in local government administration ea is frequently used to assist entities to understand its swot. the major tools that this study employed is political, economic, social and legal (pesl) to form the ea of local government administration in developing states. pesl cogitates factors that impact local council administration environment. it is a microeconomic and macroeconomic tool designed to better comprehend the internal and external environments through more in-depth environmental study. the many components of pesl analysis are alphabetically listed below. political: the extent of other layers of government intervention in an organization's functioning is referred to as political problems. taxes, regulations, elections, and political stability are all major problems. economic: according to mukoro (2005), economic factors such as financial institutions, private sector, natural resources, technology, and agriculture significantly impact public service organizations. administration in industrialized countries prioritize the overall health of its economic variables, such as interest rates, growth, employment, inflation, and business opportunities are just a few examples. a new government administration, for example, may analyze the existing status of the economy to determine its viability. economic factors have an impact on a council's long-term revenue and costs. social: alterations in demographics, safety and health-related attitudes, and technological advancements. these are all instances of societal problems. legal: the type of local government organizations and their legal framework are determined by laws. political environmental and local government administration local government administration political environment values are: global sustainability research global scientific research 48 ➢ the utilization of resources ought to fulfill the combined requirements of all individuals: lg aims to serve individuals in communities, while democratic thought suggests local government exists for individual benefit, not financial support. ➢ citizens' direct participation in political affairs and decision-making is crucial for political environmental analysis of local government, through meetings of ratepayer associations, vigilante groups, and social/political organizations. ➢ democratic principles require local government branches to be responsible, sensitive to public needs, and understand their public accountability, requiring frequent interactions with the electorate. ➢ local government is viewed as a crucial training ground for mass political education and mobilization, requiring responsible management of program effectiveness to efficiently satisfy needs. marshall (1965) was clear in declaring that one of municipal government's main goals should be to promote sound political awareness. the populace gains knowledge about how to spot a fake politician, steer clear of choosing an unscrupulous or inept representative, engage in productive debates, balance spending and income, and plan ahead. a public spirit of political consciousness and awareness will emerge, grow, and mature as long as local government is in place. economic environment and local government administration strategic planning is a crucial aspect of policy-making, enabling organizations to learn about effective strategies and make informed decisions. local policymakers often have a good understanding of their cities, but it's doubtful that they have all the information needed to create successful local economic development programmes. the administrators might not be well informed about relevant economic conditions in their cities at pre inauguration point as demonstrated by so many administration in developing nations such as nigeria with statement like “the economy we met was more sick than we think”, lg administrators often lack awareness of new economic opportunities, despite entrepreneurs having better knowledge of these opportunities than civil servants. hence lg leaders or administrators having entrepreurial economic mindset will go a long way in attaining economic development of the council and add to national economic development plan. local government administration's economic environmental analysis is crucial for developing capacity in economic policies and providing valuable insights for policy makers. it is essential for local governments to produce strategic plans internally, as outsourcing to outside experts can lose learning opportunities of aroghene and akpoyibo (2023). economic development and growth are measured by the increase in market value of goods and services produced within a locality. national economic development programs depend on local initiatives, as national governments lack the ability to implement programs across a nation. uzor & ikenga (2023) noted that rapid economic development and social well-being are crucial for developing countries, requiring sufficient growth to improve the material standard of living of the population. social environmental analysis and local government administration the physical infrastructure that supports daily life and work within local council are the social aspect that needs analysis. these factors especially the compact social and cultural infrastructure beautiful natural environment, high-quality post primary educational institutions,roads, sewers, market, leisure parks, motor park and other social amenities systems are the major component of what can promote the economic and social well-being of members of the council. global sustainability research global scientific research 49 nepotism in nigeria's public administrative system hinders supervision and control due to prioritizing loyalty to family, friends, and ethnic groups over nation loyalty. merit is not the criterion used to determine who gets appointed to public office or what contracts are awarded, which encourages corruption and mediocrity. another way to look at the public sector is as a faceless entity or "national cake" that those who are lucky enough to be near it should cut and consume. the larger your slice, the more intelligent people think you are. the same society considers people who have visited the halls of power but have accomplished nothing to be extremely stupid. even their own families despise and mock them. the result is looting of the public treasury by public officers, politicians, the military et cetera. aroghene (2023) pointed that fraud activities in an organisation is internal or external. internal in respect of those that man the organisation which comprises of shareholders, directors or administrators employed, appointed or elected to run the day to day of the firm or administration. this have impoverished the country and made the transparency international to rate most developing states as one of the most corrupt nations in the world despite the acclaimed fight against corruption. other social environmental factor that needs evaluating includes: copy-catism in nigeria's political administration, influenced by european styles, may lead to cultural conflicts and hinder public sector productivity due to differing societal values. legal principles of local government administration the legal framework and nature of local government (lg) structures are determined by a country's constitution and other laws. this analysis is crucial for assessing the viability of a metropolitan area and determining restructuring options. the constitution, national legislation, state legislation, and by-laws guide lg operations and provide a framework for determining restructuring options. legality provides a framework for lg officials, politicians, and stakeholders to determine the optimal design for their system, ensuring true value realization through strategy, structure, and technology. legal factors therefore, involve the constitutional position on the place of lg in developing states, which has to with their existence, functions, limitations, right and autonomous status that will enable build a capacity to operate. for instance in nigeria the 1999 constitution section stipulate the legal status of the lg administration, their authority, finance, functions and obligations. theoretical framework development administration theory (dat) the dat theory was popularized in the early years of comparative public administration, tracing back to riggs, montgomery, and esman's work of 1970 the development administration theory (dat) is a goal-oriented, action-driven theory that focuses on evaluating administrative structures at developmental phases. it emphasizes the administration of development and the development of administrative capacities within state institutions, promoting political, economic, and social agendas. empirical framework mukoro (2005) in his study of the impact of the environment on nigeria’s public administration, claimed that both external (caused by the environment) and internal (self-inflicted) issues cloud the discipline and practice of public administration in nigeria. these issues have a detrimental effect on government employees and public institutions, making it difficult for the government to provide the citizens' demands while maintaining its objective global sustainability research global scientific research 50 commitment to the poor outcomes of administrators' work. the study analyzed nigeria's administrative machinery, revealing the persistent negative synthesis of failure due to environmental factors impacting leadership, administration, and citizens. the paper looked at pesc becomes mutually reinforcing on the system. this work is in line with the study of mukoro (2005) and his assertion that environmental factors could have an impact on the performance of public institutions which local government administration is part of. also, in a study conducted by alaoetal.(2016) they investigated environmental factors and lga in nigeria: a study of ede north and ede south local government, osun state, nigeria (1999-2014) the study discovered that the main environmental factors were imperialism, the godfather mentality, dishonesty, excessive social pressure, inadequate funding, and excessive state government intervention. the effects of traditional institutions, ethnicity, and religion were not as noticeable. the paper also discovered that if section 8(6) of the 1999 constitution is changed to lessen the lording influence of the state government, it may be possible to address the political class's lack of desire to see local government succeed as well as the privileged people's excessive expectations for personal gain. in line with this study, shamsuddin & siddigbalal (2013) in an investigation of challenges of lga; an appraisal of nigerian noted that local government in nigeria faces series of critical challenges like creating critical social services and how to sustain them. the study shows that series of social amenities and performance of lg has the populace lose hope the inability of nigeria's lga as an institution to address persistent issues faced by the populace at large further suggests a lack of satisfaction with governance and, as a result, slows the populace's ability to become more involved in this grassroots administration. the purpose of local government, its operations, and the issues surrounding accountability and good governance were all examined in this paper. the federal republic of nigeria's constitution should be changed to enable local government authorities to deliver the essential goods and services to the populace. this is done by outlining the factors that work against the administration of local governments in nigeria and identifying areas where they can contribute to development.the finding of this study also created the gap to shows that certain variable outside the constitutional amendment is needed for local government to optimize it objectives. such variable are the internal and external environmental factor this study intend to reveal. research method the study utilized a survey research design to analyze data, focusing on 600 individuals from six geo-political zones, covering the entire country due to its vast nature. primary data was collected through five likert scale structured questionnaires, with a sample size of 333, using yamane's formula. as such 333 structured questionnaire was distributed and 240 was retrieved and formed the sample size. the data was analyzed using frequency tables, while the pearson product moment correlation co-efficient (ppmcc) denoted by "r" and coefficient of determination r2 were used to test the research objectives. ppmcc can be calculated using a simpler equation based on the deviations of the variables from their means adopted in aroghene & imene, 2023. the formular is stated thus as: ppmcc (rxy)= ∑ x y _ equation (1) √ ∑x2∑y2 where: __ x = x – x (deviation of weighted answer options from their mean) global sustainability

options have an average of 3, and the frequency response options have an average of 48, according to the model's estimation. by using equations one and two to derive the ppmcc and r2 for hypothesis one, the correlation was found to be 0.7346. this value is an indication that political environmental analysis and global sustainability research global scientific research 58 optimal attainment of local government administration objective in developing countries is strongly correlated and the relationship is positive. this showed that when local government administrators gives attention to the political state of their council, there is tendency of them actualizing optimum objective of its existence. the coefficient determination (r2) of 54% shows that variation in optimal attainment of local government administration objective is due to 54% variation in political environmental analysis . the 46% remainder is due to the disturbance term. this finding agrees with the opinion of mukoro (2005)in his study of the impact of the environment on nigeria’s public administration similarly the ppmcc for the second hypothesis stood at 0.5256. again the coefficient is an indication of a strong and positive correlation between economic environmental analysis and optimal attainment of local government administration objective in developing countries. based on the coefficient, it would be safe to imply that the level of economic evaluation conducted by local government administrators will determine the level of actualization of her objectives. the r2 (28%) for hypothesis 2 shows that variation in optimal attainment of local government administration objective is as a result of 28% variation in economic environmental analysis. the rest 72% is held accountable to the error term. similarly, the ppmcc for hypothesis three is 0.8749 with an r2 of 77%. the value of the ppmcc showed that social environmental analysis and optimal attainment of local government administration objective in developing countries is strongly and positively correlated. while the r2 showed that change in optimal attainment of local government administration objective is as a result of 77% change in social environmental analysis. the rest 22% is as a result of the error term. in conclusion, the ppmcc for hypothesis four is 0.4452 with an r2 of 20%. the value of the ppmcc showed that legal environmental analysis and optimal attainment of local government administration objective in developing countries is moderate and positively correlated. while the r2 showed that change in optimal attainment of local government administration objective is as a result of 20% change in legal environmental analysis. the rest 80% is as a result of the error term. conclusion and recommendations the study explored the effects of environmental analysis on optimal attainment of local government administration objective in developing countries (a study of nigeria). it was reveal that local government operate in a strategic environment that deal with the people of at the grass root hence its actualization of her objective is key to a better society. from the tested hypotheses of political, social, economic and legal environmental analysis and optimal attainment of local government administration objective in developing countries is strongly correlated and the relationship is positive significant. based on the findings the study recommend that local government administrators should prioritise analysis or evaluation of internal and external environment such as political, economic, social and legal state of their local government area pre and post inauguration in order to achieve optimum actualization of her objectives. this will enable them know the present state of the council, predicting the future, recognizing threats and allowing them to develop a response strategy, assisting in the achievement of expected goals and increasing its effectiveness. the study also recommend that local governments need to vigorously pursue their own complementary economic development policies in order to fit into the national development plan. local government administrators should support social broad community initiatives which encourage an asset-based approach to addressing local concerns. rather than focusing solely on a community's problems and negative pressures, the approach encourages the identification and development of strengths in order to expand local capacity and opportunities. local governments global sustainability research global scientific research 59 can create or support opportunities for people to gather for social, educational, recreational, or cultural purposes, which will assist her in gathering appropriate feedback and propelling solutions. declaration we declared that this work is a result of our research efforts. acknowledgment: all authors whose work were useful as cited in this research are acknowledged funding:

corresponding author: michael t. ang: archmykelang@gmail.com received: 13 august, 2023, accepted: 24 november, 2023, published: 28 november, 2023 abstract although walkability studies have been pronounced and recognized as an important factor for sustainable urban development, few studies have focused on calculating a reliable walkability index that captures the multifaceted dimensions of urban mobility. hence, this study aimed to formulate a model walkability index for soccsksargen region as the basis for urban development policies in achieving sustainable mobility. using a convergent mixed methods design, data were collected from 399 pedestrians, five professional design organizations, and 2 public health experts. through a transdisciplinary approach, it utilized statistical techniques such as descriptive statistics, inferential statistics, and multivariate analysis. for the qualitative findings, data were analyzed using quirkos and maxqda software. likewise, exploratory factor analysis (efa) was employed to derive the key walkability factors for formulating the walkability index model. data revealed that all groups of experts were similar in identifying safety, comfort, and aesthetics as walkability attributes. on the contrary, only the transdisciplinary design professionals considered anthropometric measures and activities as walkability attributes aside from those previously mentioned. likewise, the converged data provided substance in developing the model walkability index (mwi) for soccsksargen region. the resulting mwi discussed in the study represents the convergence of transdisciplinary efforts integrating safe roadway design concepts and sustainability considerations. furthermore, the study offers a holistic assessment of walkability, enabling stakeholders to foster the creation of future walkable urban communities that are safe, healthy, and environmentally conscious. keywords: soccsksargen; walkability; convergence; transdisciplinary; sustainability; safety index introduction the rapid concentration of the population in urban areas poses many challenges to sustainability among these, mobility emerges as one of the main generators of externalities that hinder the achievement of the sustainable development goals (cayetano medina-molina et al 2022). charlie s. taclendo: charlie.taclendo@msugensan.edu.ph ava clare marie o. robles: avaclare.robles@msugensan.edu.ph https://www.jescae.com/index.php/gssr/issue/archive global sustainability research global scientific research 59 as urban populations continue to grow, the need for sustainable and efficient mobility approaches becomes increasingly imperative. walking is undoubtedly a sustainable and healthy mode of transport. walking as a viable means of transportation has become the focus of sustainable development policies (macioszek et al 2022). however, the decision to walk is influenced by many built environment and streetscape attributes (fonseca et al 2022) this dissertation focused on developing a comprehensive model walkability index specifically tailored for the urban mobility context of the soccsksargen, a region situated in the southern part of the philippines. the soccsksargen region, comprising the provinces of south cotabato, cotabato, sultan kudarat, sarangani, and general santos city, is characterized by rapid urban growth and increasing transportation demands (national economic and development authority, 2022). given the region's unique geographical, cultural, and socioeconomic aspects, a transdisciplinary research approach is adopted to address the complex interplay between architecture and civil engineering, urban planning, transportation engineering, environmental sustainability, and public health (loorbach et al., 2017; mehmood et al., 2022). the overarching objective of this research is to create a robust and reliable walkability index that captures the multifaceted dimensions of urban mobility in the soccsksargen region. this index will serve as a valuable tool for designers, planners, policymakers, and researchers to evaluate the walkability of different urban areas within the region and identify opportunities for improving pedestrian infrastructure, enhancing connectivity, and promoting sustainable transportation modes (schoner et al., 2018). understanding how urban space influences citizens’ perceptions of walkability is critical to designing efficient pedestrian planning policies and guiding future research in this field (fonseca 2022). a transdisciplinary research approach is employed to tackle the complexity of the research problem, involving collaboration between various disciplines such as architecture, civil engineering, landscape architecture, urban planning, transportation engineering, and public health, including pedestrian users. transdisciplinary research can solve problems that cannot be solved in one discipline as the approach is able to connect different disciplines and stakeholders and guarantee a sufficient and efficient consideration of all relevant factors for real-world problems (stinder et al 2022). this transdisciplinary collaboration engages a holistic understanding of the region's urban mobility challenges and enables the integration of diverse perspectives, expertise, and methodologies to develop an inclusive walkability index. the study adopts a convergent mixed-methods research design, combining quantitative analysis, spatial modeling, and qualitative assessments to capture both objective and subjective aspects of walkability. through the integration of pedestrian surveys, interviews, and participatory engagement, the research aimed to generate a comprehensive understanding of the factors influencing walkability in the soccsksargen region (cerin et al., 2017). this transdisciplinary research approach ensures a nuanced, people-centered and contextually relevant model that reflects the unique characteristics and needs of the region. by developing a robust walkability index, this dissertation contributed to the existing body of knowledge on urban mobility and provided practical insights for sustainable urban planning in the soccsksargen region. the findings of this research can inform policy interventions, infrastructure investments, and community engagement initiatives aimed at enhancing walkability, promoting active transportation, and fostering healthier and more sustainable urban environments (giles-corti et al., 2019; sallis et al., 2016). this dissertation represents a pioneering effort in the development of a model walkability index tailored to the urban mobility context of the soccsksargen region. through its transdisciplinary research approach, this dissertation aimed to provide a comprehensive understanding of the complex interplay between urban planning, global sustainability research global scientific research 60 transportation engineering, environmental sustainability, public health, and pedestrian users. the results of this research hold significant potential for fostering sustainable urban development and improving the quality of life for residents in the region. literature review defining walkability the term walkability is used to describe the extent to which the urban environment is pedestrian-friendly, usually by quantifying multiple built environment attributes at the neighborhood scale (fonseca et al 2022). it encompasses the design, infrastructure, and amenities of an area that encourage and enable individuals to walk for their daily needs, recreation, or commuting purposes (litman, 2020). walkability is often assessed based on criteria such as sidewalk availability and quality, street connectivity, presence of crosswalks, pedestrian safety features, land use patterns, access to public transit, and the proximity of essential destinations like schools, workplaces, shops, and parks (mccormack et al., 2018). the concept of walkability only started to be used in transport and planning studies in the early 2000s, but rapidly became a widely used concept in sustainable mobility and other disciplines (fonseca et al 2022) this concept plays a crucial role in creating healthier, more sustainable, and vibrant communities, as it promotes physical activity, reduces dependence on automobiles, improves air quality, fosters social interaction, and enhances the overall quality of life (litman, 2020; mccormack et al., 2018). the urban areas in soccsksargen, depended much on personalized public commuter systems such as tricycles and habal-habal, relegating walking to the sidelines. walkability has become a major theme of urban research, and also a key goal of various urban design practitioners (forsyth, 2015; winters et al., 2017) such as architects, planners, engineers, landscape architects, etc. however, to comprehensively address the complex and interconnected challenges associated with walkability, it is crucial to adopt a transdisciplinary approach. by involving multiple disciplines, the multifaceted aspects of walkability can be explored, and innovative solutions will truly enhance the pedestrian experience (marans & stimson, 2011). walkability as a sustainable mode of urban mobility non-motorized or active transportation (walking, cycling, and its variations) plays an important role, and significant and distinct responsibilities in a well-functioning transportation system walking is a practically ubiquitous human activity that allows for mobility, exercise, and enjoyment. the ideal practice is to have 10-20% of trips made completely through non-motorized modes, while the majority of motorized trips include non-motorized linkages, such as connecting to public transportation and between parked cars and destinations. pedestrian environments include parking lots, transportation terminals, airports, and commercial districts. improving non-motorized transportation is frequently one of the most cost-effective methods to improve motorized transportation. walking and cycling are both low-cost modes of transportation. they are typically relied on by physically, economically, and socially disadvantaged persons, so enhancing non-motorized transportation can assist in achieving social equity and economic opportunity goals. the most prevalent kind of physical activity is active transportation and the most practical strategy to promote public fitness and health is to increase the frequency of global sustainability research global scientific research 61 walking and cycling. non-motorized modes can help planners meet their goals in the reduction of traffic congestion, consumption of energy, and pollutant emissions they can also aid in the achievement of land use planning goals including urban redevelopment and more compact "smart growth" development. the most accessible public realm or spaces include a large number of pedestrian contexts (sidewalks, walkways, and hallways). many useful behaviors (socializing, waiting, buying, and eating) take place in pedestrian contexts, and the quality of these spaces has an impact on them. to attract clients, shopping areas and resort communities rely on walkable environments. popular recreational activities now include walking. improving the pedestrianbuilt environments helps users in terms of enjoyment and health, as well as supporting related industries such as retail, recreation, and tourism. the popularity of walking is still inherent as much research suggests that people continue to walk for transportation and enjoyment despite the availability of motorized vehicles. in many cases, improving walking conditions while restricting motor use is the greatest method to improve urban transportation. it improves overall accessibility to locations in terms of convenience, comfort, and affordability. walking is the most cost-effective and environmentally friendly among other modes of transportation and recreation. its potential cost and resource savings are often highlighted (litman 2018). this high value placed on driving and the low value placed on walking in conventional planning reflects how transport is measured (litman, 2018). because short trips, non-work travel, travel by minors, recreational travel, and nonmotorized links are most often overlooked, and most travel surveys undercount nonmotorized travel. most travel surveys, for example, label "auto-walk" or "walk-transit-walk" trips as "auto" or "transit." walking links, regardless if they happened on public driveways or rights-of-way and consume as much time as motorized links, are also left unnoticed. according to previous research by zapata-diomedi et al (2017), in brisbane, nearly 80% of adults travel for work or education by private cars about 20% of urban trips are conducted by active transport. while in germany, just 22% of trips are entirely made on foot, although 70% include some walking. a report from the united kingdom states that walking accounts for 2.8 percent of overall mileage, 17.7% of travel time, and 24.7 percent of trips. walking appears negligible when it is measured solely in terms of travel distance, however, when it is measured in terms of trips, travel time, or even outdoor exposure to public spaces and social infrastructure. because by nature non-motorized transport has slower speeds than its motorized counterpart and considering commuters waiting at bus stations or loading bays, or just merely standing in front of store windows, non-motorized passengers may account for only 5% of person-trips but 40% of person-minutes of public exposure. as a result, how people view the transportation system and the local environment is heavily influenced by their walking conditions. active modes of transportation have become one of the beacons of sustainability/. in the 2030 agenda for sustainable development, the united nations has determined that countries and regions should provide safe, affordable, accessible, and sustainable transportation for their citizens (zafri et al; 2021) the influence of the built environment on walking recent multidisciplinary transport studies that link transportation planning to health studies have acknowledged that walking helps to maintain the physical and mental health of all ages by preventing a variety of health problems (mohammed 2017), and as a result, researchers are now more concerned with the built environment determinants of active transportation emphasizing the need to identify what are the spatial factors that would influence and condition active transportation. the term built environment refers to the human-made surroundings that provide the setting for human activity (kaklauskas 2016). global sustainability research global scientific research 62 the positive and negative effects of interactions between pedestrians and the built environment influence the pedestrian walking experience. these spatial features are thought to have an impact on a person's decision to walk. the built environment is increasingly recognized as a key driver of walking and physical activity (liao et al.,2020). walking is now being acknowledged by planners as an important means of active urban transportation as support for urban sustainability grows. the popularity of urban walkability is growing due to rising fuel costs, fuel availability, traffic congestion, pollution, and other urban difficulties induced by a significant reliance on fossil fuel-driven cars. environmental factors affecting pedestrian satisfaction to obtain insight into urban design techniques that can promote both pedestrian satisfaction and activities, kim, park, and lee (2014) explored the correlations between pedestrian satisfaction and several built environment characteristics. the authors illustrated the significant correlation between the satisfaction of pedestrians and the quality of urban pedestrian environmental factors using econometric instruments, indicating the importance of taking psychological factors into account when studying walkability, such as different pedestrian groups and trip motives. the built environment is shaped by transportation investments and land-use allocation and therefore hinders or encourages walking (wang 2021). details of environments, including sidewalk and crossing quality and aesthetics, are believed to affect people's confidence, comfort, and safety for walking in neighborhoods (sallis et al., 2016), but they have been less well-studied. these attributes were identified using the neighborhood walk audit and through actual observational measures on users' or stakeholders’ preferences. walkability increases exponentially when people feel a sense of control over the streets they walk. conversely, streets fail when they seem to be controlled by no one. walkability and street vitality are important factors in shaping urban life on and around the street. pedestrian experience principles in measuring walkability walkability is a key concept of sustainable urban development (yamagata et al, 2020). leyden 2003 further states that walkable communities have the potential to contribute to the well-being of communities by way of reducing carbon emissions and improving climate resiliency. walkability refers to the degree of walking comfort in a walking environment for pedestrians (kari 2016). dong yeong jong (2017) states that pedestrian’s cognition, affect, and behavior occur from the interaction between pedestrian passage and its related environment which he called the pedestrian experience and that to promote walkability, it is necessary to design walking environments according to the pedestrian experience (px) principles. yamagata et al (2020) in their study of the experiential model for the walkability of kyojima district in japan identified the following as the five thematic pedestrian experience (px) principles for walkability :(1) activity (2) beauty/aesthetics (3) comfort (4) anthropometric and (5) security/safety. these themes are further subdivided into various indices. these principles are a set of guidelines developed by the city of yamagata in japan to promote a pedestrianfriendly urban environment. the key elements of the yamagata px principles and their significance in enhancing the pedestrian experience were identified as follows: human-scale design: the yamagata px principles emphasize the importance of human-scale design, which involves creating urban spaces that prioritize the comfort, safety, and convenience of pedestrians. this includes features such as wide sidewalks, pedestrian-friendly crossings, ample seating, and well-maintained public spaces. global sustainability research global scientific research 63 by designing for human scale, the principles aim to create a walkable environment that promotes social interaction and enhances the overall pedestrian experience. universal accessibility: the yamagata px principles emphasize the importance of universal accessibility, ensuring that the urban environment is inclusive and accommodating for people of all ages, abilities, and mobility levels. this involves providing barrier-free access, installing ramps and elevators, and considering the needs of individuals with disabilities when designing pedestrian infrastructure. universal accessibility ensures that everyone can fully participate in and benefit from the pedestrian experience. safety and security: safety and security are paramount in the yamagata px principles. the principles emphasize the importance of creating a safe and secure environment for pedestrians through measures such as well-lit streets, clear signage, and effective traffic management. these measures help reduce the risk of accidents and promote a sense of security among pedestrians, encouraging more people to walk and explore the urban environment. integration of nature: the yamagata px principles recognize the value of incorporating nature into the urban environment. they emphasize the integration of green spaces, trees, and vegetation to enhance the pedestrian experience. by incorporating nature into the urban fabric, the principles aim to create a more pleasant and visually appealing environment that contributes to the overall well-being of pedestrians. cultural and historical preservation: the yamagata px principles highlight the significance of preserving and showcasing the cultural and historical heritage of the city. they encourage the integration of cultural elements, historic landmarks, and traditional architecture in urban design. this approach fosters a sense of identity and pride among pedestrians, as well as promotes a deeper appreciation for the city's cultural heritage. implementing the yamagata px principles requires collaboration between urban planners, architects, transportation experts, and community stakeholders. by adhering to these principles, cities can create pedestrianfriendly environments that enhance mobility, health, and quality of life. the yamagata px principles serve as a valuable framework for cities worldwide to guide the development of urban spaces that prioritize pedestrians and create vibrant, livable communities. elements of the pedestrian experience (px)

regional development plan in the philippine setting, before the introduction of automobiles by the americans, walking, together with animaldriven vehicles, was then the dominant mode of transport. however, as cities experience rapid urbanization, the volume of vehicles also increases which resulted in traffic congestion and the deterioration of outdoor air quality due to increased carbon emissions from fossil fuel-driven vehicles. this phenomenon is happening in almost all major cities in the country, soccsksargen region included. soccsksargen’s regional development plan identifies ten (10) preferred medium-term strategies focusing on peace, environment, infrastructure development, and safety and resiliency. strategy number 3,4,5 specifically identifies improving social infrastructure and building community resiliency that integrates disaster risk reduction, and climate change action (neda xii). social infrastructure helps in recognizing the public spaces that are often overlooked and undervalued. it draws attention to the breadth, depth, and textures of sociality that can be afforded by different urban environments (latham and layton 2019). klinenberg (2018) defines social infrastructure as “public institutions, such as libraries, schools, playgrounds, parks, athletic fields, and swimming pools, including sidewalks, courtyards, community gardens, and other spaces that invite people into the public realm”. social infrastructure, despite its role in helping recognize the public dimensions, are most often been not prioritized and these public spaces have always been de-prioritized in urban development. in compliance with the strategies identified by the soccsksargen regional development plan, and recognizing the need to improve the social infrastructure and safety of public spaces, the general santos city public safety office (pso) recently crafted its local public transport route plan (lptrp), and among its goal is to manage both the motorized and non-motorized mode of transport in the city. its primary aim is to find a solution to the issues created by the huge volume of tricycles plying the city and to reduce the street hazards and environmental pollution emanating from the high density of motorized tricycles ad private cars plying the urban global sustainability research global scientific research 65 streets. among the strategic plan of the pso, is to encourage active transport, biking, and walking, especially in the dense central business district. recently the department of human settlements and urban development (dhsud) issued memorandum circular 2021-010 mandating all local government units to enhance the climate and disaster risk assessment process to ensure that these are integrated into local development and land use plans. the literature review provides a comprehensive overview of the concept of walkability, its importance in promoting sustainable urban mobility, the influence of the built environment on walking, and the principles of the pedestrian experience. however, there are notable research gaps and areas for innovation that warrant attention in this study. the literature review highlights the reliance on personalized public commuter systems in soccsksargen, relegating walking to the sidelines. a critical research gap lies in understanding the specific challenges and opportunities for enhancing walkability in this context. while previous studies acknowledged the need for a transdisciplinary approach to address the complex challenges of walkability, they fall short in providing specific examples or methodologies for implementing innovative collaborations between disciplines such as urban planning, architecture, public health, and sociology. this could involve developing frameworks for effective communication and decision-making among diverse stakeholders to optimize walkability outcomes. this research focused on investigating and harmonizing the meaning of walkability from the viewpoints of transdisciplinary design professionals and groups involved in the development of the built environment (environmental planners, architects, engineers, transportation experts, public health officials, and pedestrian users.) and in the process identify the attributes of walkability and subject them to a perceptual user survey to determine the individual weights of each attribute has in conditioning pedestrian willingness to walk and integrating all these weights into the development of a walkability index in the context of the stipulated study area. in conclusion, addressing these research gaps and exploring innovative avenues will contribute to a more nuanced understanding of walkability and inform practical strategies for creating pedestrian-friendly urban environments. methodology study location and population the research locale is soccsksargen, short for south cotabato, cotabato, sultan kudarat, sarangani, and general santos, a region situated n in mindanao. south of the philippines with a total regional population of 4,901,486. due to the limitation of time and resources, the research focused only on key urban districts of general santos city: namely: barangay dadiangas east, barangay dadiangas west, barangay dadiangas south, barangay dadiangas north, barangay lagao, barangay dadiangas city heights and barangay bula as the model study area in consideration of its status as a highly urbanized city. the study adopted convergent mixed method research, an approach combining the simultaneous conduct of qualitative and quantitative data collection and analysis methods to comprehensively understand a research topic. convergent mixed methods research involves collecting both qualitative and quantitative data. qualitative data were collected through interviews, focus groups, or observations, while quantitative data was gathered through surveys and secondary data analysis (creswell & creswell, 2018). the qualitative data collection process was global sustainability research global scientific research 66 guided by the research questions and was designed to capture a rich understanding of the phenomenon under investigation. sampling and data collection the sample size is an important characteristic of any empirical study in which the aim is to make an inference about a population from a sample (bujang & adnan, 2016) it is essential for the researcher to estimate an appropriate sample size to produce reliable results using the statistical procedure (adhikari 2021). in situations when the population is finite and the researchers do not have enough knowledge about the population's behavior (or distribution of behavior) to determine the optimal sample size, the slovin formula can be used to estimate it (adhikari 2021) the sampling frame for the quantitative survey was pedestrians 15 years and above who utilized the pedestrian facilities within the study area. the sample size for the survey had a 95% confidence level and a margin of error of 5%. slovin’s formula was used to determine the total number of respondents in the study from the urban population of 136,987, the computed sample size is 399. the study utilized the probabilistic sampling design as a stratified random method. the sample was stratified within the four perimeter streets bounding the study area in particular, on the strategic intersections. this method involves two data-gathering procedures done simultaneously, the quantitative pedestrian survey (creswell, 2018) and the overall intent of this design is to have the qualitative data help explain in more detail the convergent quantitative results. this study employed a stratified sampling design from the four quadrants of the study locale. this sampling design is appropriate to ensure a proportional representative for the four urban barangays of general santos city. further, the sample size for the survey was determined using a 95% confidence level and a .05 margin of error. focus group discussions (fgd) and key informant interviews (kii) were used to gather the opinions of the various professional disciplines. a total of five (5) focus group discussions (fgd) with 6 to 10 participants each, as suggested by krueger and casey (2002), and three (3) key informant interviews (kii) were conducted. fgds were conducted based on the guidelines recommended by meyer (2021). before conducting fgds and kiis, participants’ consent was sought by signing informed consent. data analysis the data gathered in this study was analyzed using multiple data analysis procedures. on the one hand, quantitative data was analyzed using descriptive statistics, interpreted based on mean value and exploratory factor analysis. qualitative data gathered through focus group discussion (fgd) and key informant interviews were transcribed, translated, coded, categorized, and analyzed using quirkos 2.4.2 (2021), a software package for qualitative data analysis. a total of 399 pedestrians participated in the survey. after validation of the accomplished questionnaires, all 399 interviews were used in the data analysis; the distribution of the survey respondents by survey location is presented] descriptive statistics were used to determine the profile of the respondents. global sustainability research global scientific research 67 ethical consideration this study received ethical approval from the institutional ethics review committee of mindanao state university, general santos city. results and discussion socio-demographic profile of the respondents the pedestrian respondents consisted of 215 female respondents comprising 53.9%, and 184 males, comprising 46.1% of the total 399 respondents. this shows that there are slightly more female pedestrians than male pedestrians, by as much as 7.8% more. this is similar to the study conducted by sallis et al. (2016), who found that women were likelier to walk than men. the mean age of the respondents was 27.63%, the youngest age was 15, and the oldest was 73 years old. the survey shows that pedestrians are relatively young, with 27.63 as the mean age. however, it must also be noted that the age range is quite broad, with the youngest at 15 and the oldest at 73. this is validated by the study conducted by sallis et al. (2016), which finds that the age group most drawn to walking is adults aged 18-34 years old. in terms of respondent distribution by income group, the researcher utilized the philippine statistics authority fies for 2021. most survey respondents had a monthly family income of below p7,833.00. this accounted for 195 responses, or equivalent to 48.90%. this was followed by income of p7,834.00 to p11,333.00, 64 (16%); then p13,501.00 to p15,833.00, 36 (9%). three (3) had a monthly family income of between p37,168.00 to p71,500.00, and three (3) of at least p71,501.00, which accounted for 0.8%. the initial observation is that many of the current pedestrians plying the streets of the study area came from the low-income group whose monthly family income is below p7,833.00. in particular, research has shown that walkability is the preferred mode of transportation for low-income groups (gehl, 2010). this is likely because walking is a low-cost, accessible, and convenient option for those who may not have access to a car or public transportation. preferred walkability attributes five focus group discussions (fgd) among the design professional organization to identify themes from the similarities in their preferences; the distribution of participants in the fgds are as follows: 10 environmental planners, 8 architects, 6 civil engineers, 5 landscape architects, and 3 transport scientists the mean age was 42.25. the youngest participant was 27, and the oldest was 62 years old. three themes were extracted from the data processed through quirkos software. these are: theme 1: creatively artistic (aesthetic attribute) aesthetics in walkable environments contribute to creating a distinct sense of place and fostering a sense of local identity. unique architectural styles, historical references, or cultural elements incorporated into the urban fabric global sustainability research global scientific research 68 help to establish a sense of character and place attachment (lynch, 1960). aesthetically pleasing streetscapes that reflect the local context and heritage contribute to a stronger sense of community and pride, making the walking experience more meaningful and memorable for residents and visitors alike. one participant mentioned: ["in terms of aesthetic, i know maybe it's not really something that is within the design aesthetic but anything that shows festivity or the fiesta' spirit would really, you know, encourage people to walk. i mean, we've seen experiences where you know, where people who don't really walk, but if there are bandiritas there, you know, people would walk. as long as there's that aesthetics, the colorful, the goody and you know the idea of something top of the ordinary people would walk"] (fgd: pala 10/01/22) aesthetics can influence the perceived safety and comfort of walkable environments. well-maintained and visually appealing streetscapes create a positive impression of safety and security (wener & evans, 2007). adequate lighting, clear sightlines, and aesthetically pleasing design elements contribute to pedestrians' feelings of comfort and security while walking (apa, 2017). by integrating aesthetics into the design of walkable spaces, designers can positively influence the perception of safety and comfort, encouraging more people to engage in active transportation. theme 2: sense of protection and security the physical safety of pedestrians is a fundamental component of walkability. safe infrastructure, including wellmaintained sidewalks, crosswalks, and pedestrian-friendly intersections, plays a crucial role in preventing accidents and injuries. according to the american planning association (apa), walkability should prioritize features that protect pedestrians, such as adequate lighting, clear signage, and traffic calming measures (apa, 2017). ensuring physical safety not only reduces the risk of accidents but also promotes confidence and encourages more people to engage in active transportation. perceived safety refers to the subjective sense of security that individuals experience while walking in a neighborhood. it encompasses factors such as personal safety, visibility, and the absence of crime or vandalism. perceived safety is a critical consideration in walkability, as it directly influences people's willingness to walk and their overall satisfaction with the environment. research has shown that individuals are more likely to engage in. the focus group discussion among the design professionals gathered various viewpoints on sidewalk safety. one participant from the philippine association of landscape architects (pala) took note of safety as a major concern; the lack of it in pedestrian sidewalks was glaring since pedestrians were seldom recognized as part of the roadway planning process: ["basically, our road network here does not provide a safe area for pedestrians for people to walk along pedestrian, so, that's basically one big concern because he is not even identified, so, basically the question on safety is very much a big concern"] (fgd-pala 10-1-22) theme 3: enjoy its comfort physical comfort is a fundamental aspect of sidewalk design. sidewalks should be designed with attention to factors such as smooth surfaces, adequate width, and the absence of tripping hazards. uneven surfaces, cracks, or obstacles can cause discomfort and pose safety risks to pedestrians, particularly for individuals with mobility challenges or using mobility aids. the american planning association (apa) highlights the need for sidewalks global sustainability research global scientific research 69 to be "safe, comfortable, and convenient" for pedestrians (apa, 2017). by ensuring physical comfort, sidewalks can provide a pleasant and enjoyable walking experience for individuals of all ages and abilities. environmental factors significantly influence sidewalk comfortability. providing shade through tree canopies, installing benches or seating areas, and incorporating street furniture contribute to the overall comfort of sidewalks. these features offer opportunities for rest, social interaction, and enjoyment of the surroundings a convergence of the quantitative and qualitative findings (table1) shows that there are similarities and differences between the preferences of the design professionals and the pedestrian users. to sum up the quantitative and qualitative findings on the preferred walkability attributes of walkability according to the viewpoints of various groups, data show that all groups are similar in considering safety, comfort, and aesthetics as walkability attributes. on the contrary, only the transdisciplinary design professionals considered anthropometric measures and activities that must be included as walkability attributes aside from those previously mentioned table 1. summary table of convergence of quantitative and qualitative findings on the similarities and differences in the preferred walkability attributes indicator quantitative result qualitative result code safety m = 30.81 (rank 1) ▪ we talk about safety;

it is essential to consider various factors that contribute to a harmonious and functional public space environment. these four identified key factors are labeled as (1) physical and environmental safety, (2) aesthetics, (3) convenience, and (4) ease and comfort. global sustainability research global scientific research 71 exploratory factor analysis was used in this research to determine the model walkability index, a mathematical combination of several indicators to form a single number. the model walkability index was then used to describe the entire set of indicators and allow for regional or possibly national differences between places and across time assessed. exploratory factor analysis is a statistical procedure that identifies the common variance amongst a set of observed variables or indicators and creates a factor (sarstedt 2014), in this case, the walkability index, comprised of that common variance. the factor scores were calculated with a linear equation incorporating a weighted contribution of each variable included in the analysis. the contribution in weight of each variable was relative to the amount of variance in common with the other variables. table 2. rotated component matrix of pedestrian survey results items indicators factors 1 2 3 4 1 high vehicular traffic volume .356 .565 2 presence of business establishments along sidewalk .741 3 presence of food establishments .741 4 presence of parks and playgrounds .603 .360 5 proximity to large commercial complex .422 .628 6 colorful and attractive sidewalks .746 7 presence of landscaping .724 8 nice building façade .620 9 presence of public/street art .746 10 protection from heat and rain (trees, shelterred, arcade) .534 .433 11 presence of street furniture .395 .585 12 good sidewalk surface quality .439 .589 13 unobstructed and levelled sidewalk .689 14 adequate sidewalk width .311 .652 .331 15 adequate headroom .304 .698 16 high pedestrian traffic .334 .415 17 presence of pwd ramps .530 .452 18 good outdoor air quality .678 19 presence of traffic lights .782 20 presence of pedestrian crosswalk .739 21 clear and legible signages .767 22 presence of loading and unloading bays .690 23 presence of protective rails and bollards .613 24 adequate street lighting .638 .388 25 presence of cctv monitoring cameras .721 formulating the model walkability index the derivation formula for the walkability index of soccsksargen utilized the pedestrian environmental quality index (peqi), developed by researchers at the university of hong kong. the peqi incorporates factors such as sidewalk quality, pedestrian safety, aesthetics, ease, comfort, and convenience. the peqi formula is global sustainability research global scientific research 72 derived through expert judgment and statistical analyses to determine the relative weights of each factor (cerin et al., 2007). the formula for the model walkability index is: mwi = ∑waj*naj where mwi is the model walkability index, w is the weight per attribute a, in parameter j. ni is the normalized value of attribute an in-parameter j. using group weighted indicators, the following was formulated: mwi= (〖f1〗_ave∙w_1) +(〖f2〗_ave∙w_2) +(〖f3〗_ave∙w_3) +(〖f4〗_ave∙w_4) mwi= (f1ave∙55.56%) +(f2ave∙11.11%) +(f3ave∙11.11%) +(f4ave∙22.22%) where: f1 = physical and environmental safety f2 = aesthetics f3 = ease and comfort f4 = convenience based on the pedestrian survey data and utilizing the mwi formula, the derived walkability index for the soccsksargen region is 4.33, with a maximum possible score of 5. this unitless score reflects the extent to which pedestrian sidewalk conditions support walking, as per the opinions of the survey respondents. when compared to walkability ratings from a study conducted by abaya et al. (2011) on major cities in the philippines, general santos city surpasses the walkability ratings of manila (4.14), davao city (3.42), and cebu city (3.46) (refer to table 3). this suggests that pedestrians in general santos city exhibit a stronger preference for sidewalk conditions in terms of the walkability index, outperforming the existing ratings of the three major cities in the country. table 3. walkability rating of major cities in the philippines city zoning walkability rating metro manila commercial 4.14 davao city commercial 3.42 cebu city commercial 3.46 source: eastern asia society for transportation studies 2011 conclusions in conclusion, the significance of prioritizing safety in the design of pedestrian walking environments for fostering walkability is evident. however, it is crucial to acknowledge certain limitations in the current understanding and global sustainability research global scientific research 73 implementation of safe design principles. firstly, the effectiveness of specific safety measures may vary across diverse urban contexts, warranting further investigation into context-specific factors influencing their impact. moreover, the long-term sustainability of walkability initiatives requires ongoing evaluation and adaptation to changing urban dynamics. future research should delve into the dynamic nature of urban environments, considering factors such as evolving traffic patterns, land-use changes, and emerging technologies that may influence pedestrian safety. while promoting walkability is associated with numerous public health and social benefits, it is essential to recognize potential disparities in access to safe pedestrian spaces. disadvantaged communities may face additional challenges, and future research should explore strategies to ensure equitable distribution of walkable spaces and their benefits. additionally, the current model walkability index, while valuable, may need refinement and adaptation to account for evolving urban design philosophies and community preferences. future studies should focus on refining and expanding the index to encompass a broader range of factors that contribute to the overall pedestrian experience. and lastly, the review mentions initiatives such as the soccsksargen regional development plan and the local public transport route plan, there is a need for research evaluating the effectiveness of these policies in promoting walkability. future studies should assess the implementation of such plans, identifying successes, challenges, and areas for improvement. this would contribute to evidence-based policy recommendations for other regions facing similar issues. in summary, while the promotion of walkability through safe design is a commendable endeavor with multifaceted advantages, acknowledging and addressing the aforementioned limitations will be essential for the continued success of such initiatives. future research endeavors should aim to refine existing strategies, explore innovative solutions, and ensure that the benefits of walkability are accessible to all members of diverse urban communities. declaration acknowledgment: the authors appreciate the members of various organizations of design professions for participating in the research by providing useful information and insights. likewise, the pedestrians of general santos city who willingly responded to the roadside survey funding: no funding conflict of interest: no conflict of interest declared authors contribution: all authors worked collaboratively for the completion of this paper in accordance to the names appear herein data availability: the availability of the data is purely for academic purposes and the corresponding authors maybe contacted. global sustainability research global scientific research 74 references abaya ernesto, fabian bert, gota sudhir, mejia, alvin (2011); assessment of pedestrian facilities in major cities of the philippines; east asia society of transport studies american planning association (apa).

surakshya sharma. email: surakshyasharma111@gmail.com received: 06 november, 2024, accepted: 23 november, 2024, published: 24 november, 2024 abstract jute cultivation has shown decreasing trend in recent years globally despite the prospective demand. being laborintensive, with labor making up over 70% of the entire cost and technological advancements still not evident in farmers' fields limits productivity of jute in nepal. this study aims to analyze the economic viability of jute production, factors affecting it and constraints of jute production in sunsari district, nepal. well-structured and pretested interview schedule was used to acquire required data from 120 jute cultivators of bhokhraha narsingh and duhabi municipality using random and purposive sampling technique. benefit-cost ratio analysis and multiple regression were conducted using excel 2019 and spss version 25. jute production is found profitable as shown by positive gross margin and the average benefit-cost ratio of 1.52. highest education of the family, machinery and subsidy were positively significant with benefit-cost ratio. number of economically active female members had shown negative influence on benefit-cost ratio of jute production. distance to nearest extension service center showed highly significant negative relation with benefit-cost ratio implying increasing distance lowers bc ratio by a greater extent. high cost of production and labor problem were ranked as major problem in sustainable jute production. to increase the jute productivity and sustainability, this study recommends focusing on labor issues and enhancing technology interventions. the findings of this study offer policymakers a foundation to implement strategies that strengthen jute production, fostering both economic stability and environmental sustainability in sunsari district, nepal. keywords: bc ratio; economic viability; regression introduction jute, often known as the golden fiber, is a natural fiber. it is one of the most affordable and durable natural fibers, and it is regarded as the fiber of the future (uddin & chowdhury, 2015). jute is the cash crop for the poor and the marginal farmers and it continues to be an important commodity for employment and source of income for them (kumari et al., 2018). jute (corchorus capsularis l. & corchorus olitorius l.) is the world's second most produced natural bast fiber, with an anticipated average production of 2.39 million tons in 2020/21(singh et al., 2019). the fibers are used to manufacture twine and rope, either alone or in combination with other types of fibers. jute butts, which are the coarse ends of the stalks, are used to manufacture cheap cloth. in contrast, very fine jute threads can be extracted and turned into imitation silk (islam & ali, 2018). jute has a long history of use in the sacking, carpet, wrapping fabric (cotton bale), and building fabric production industries (islam & ali, 2018). man-made synthetic global sustainability research global scientific research 75 fibers are created in many nations due to insufficient production to fulfill demand and limited geographical distribution in india, pakistan, bangladesh, and other asian countries (maiti & singh, 2019). countries are currently focusing heavily on developing eco-friendly products such as jute bags in order to reduce climate impact and save the environment. farmers are returning to jute production as the price of jute continues to rise. jute's market is rapidly expanding (islam, 2018). to meet industry demands, jute and associated fiber production must be expanded. increased productivity and increased jute cultivation area are two major ways to do this (kumari et al., 2018). by lowering dependency on synthetic materials, improving soil health through rotation, and increasing biodiversity, increased jute production could be crucial to the advancement of sustainable agriculture techniques. additionally, jute supports the creation of environmentally friendly products by offering biodegradable substitutes for plastics, which is in line with international sustainability objectives. economically, by stabilizing farmer incomes and generating job opportunities, increased jute production strengthens rural communities. despite such prospective demand, jute cultivation and area in the regions have shown changing trends in recent years. as a result, an attempt must be made to comprehend the current state of jute farming, as well as the identification of limits from the perspective of growers. the dominance of marginal and small-scale farmers in jute farming is one of the limiting elements in the process of achieving cost competitiveness, resource use efficiency, and marketing efficacy (kalita & bhuyan, 2018). technological progress is still not noticeable in the farmers' fields, and jute cultivation is labor intensive, accounting for almost 70% of the cost of human labor (s. dutta & mondal, 2021). the yield and quality of olitorius jute are now diminishing due to a lack of improved jute cultivars and other biotic stress factors. insect pests are the most important biotic stressors in jute farming. identifying the best jute varieties to grow on farms and utilizing quality tossa fibers in the jute sector industry would assist farmers in selecting the best jute varieties to grow (karki et al., 2021). in relation to this, knowing the economics of jute production and identifying the key factors affecting and/or causing variations among producers in this study area is found very imperative in the course of planning for improvement. in this regard, there was no similar study conducted on similar issue in the specific targeted study area and hence this study is meant to fill this information gap. this study sets out to analyze economics of jute farming in sunsari district, and to identify characteristics that explain variation in the economic viability of the farmers. an understanding of these relationships could provide policymakers with information to design programs that can contribute to measures needed to expand the jute production potential of sunsari district. to analyze economics of jute farming in sunsari district, the objectives are; to analyze the economic viability of jute farming, to identify factors affecting economic viability of jute farming and to identify problems associated with of jute farming in sunsari district. methodology study area sunsari district is a district in koshi zone, eastern development region, nepal at latitude 26°38′29.76″ north, longitude 87°07′44.76″ east. sunsari district is the second highest jute producing district of nepal where jute is cultivated in 1392 hectares with productivity 1.48 mt/ha. sunsari has a moderate climate. there is a lot of rainfall in the summer, and in the winter, it is quite dry. bhokraha narsingh rural municipality and duhabi municipality were selected for the study as population of jute cultivating farmers is relatively high. sources of data both primary and secondary data will be used. primary data will be collected through well prepared and pretested questionnaire to the sampled farmers. secondary data will be collected from different journals, publications, reports and different internet sites. global sustainability research global scientific research 76 sample size determination from two selected municipalities, the representative respondents will be selected to enhance reliability and validity of the study. accordingly, the sample size of the study is determined by using kothari sampling design formula, (kothari, 2004) n = n 1+n(e2) where, n = sample size n = total population e = acceptable error term (0.1) simple random sampling was done to collect data from 120 jute farmers. sampling and data collection the required quantitative data was collected through household survey using structured questionnaire which was pretested in 10 randomly selected jute growers of selected municipalities. we collected a list of jute cultivating farmers of bhokhraha narsingh and duhabi municipality and selected 120 jute growers using simple random sampling technique. the data collection was carried out by visiting each household personally and interviewing them with the help of a pretested interview schedule. in each of jute producing respondent households, the household head or any adult who had lived with the household for at least one previous crop production seasons and conversant with the farming activities of the other household members were interviewed. data analysis data collection was done by interview schedule, data was entered in spss version 25 and data was analyzed using spss version 25 and ms excel 2019. following analysis were done: gross margin analysis gross margin is the gross return over variable cost. gross margin is calculated by deducting the total variable cost from the gross return (bristy, 2020). gross margin = gross return – variable cost gross return gross return is calculated by multiplying the total amount of product with respective per unit price and adding value of by-product. gross return of jute production = unit price of jute * total production + value of by-product. net return net return or profit was calculated by deducting the total cultivation/production cost from the total return or gross return. net return = total return – total cultivation cost global sustainability research global scientific research 77 benefit cost ratio benefit cost ratio (bcr) is a relative measure, which is used to compare benefit per unit of cost. bc ratio= total return/total cost factors affecting benefit cost ratio factors affecting benefit cost ratio were identified using multiple regression (kothari, 2004). regression is the determination of a statistical relationship between two or more variables. in simple regression, we have only two variables, one variable (defined as independent) is the cause of the behavior of another one (defined as dependent variable). regression can only interpret what exists physically i.e., there must be a physical way in which independent variable x can affect dependent variable y. the basic relationship between x and y is given by y = a + bx this equation is known as the regression equation of y on x (also represents the regression line of y on x when drawn on a graph) which means that each unit change in x produces a change of b in y, which is positive for direct and negative for inverse relationships. when there are two or more than two independent variables, the analysis concerning relationship is known as multiple correlation and the equation describing such relationship as the multiple regression equation. multiple regression equation assumes the form ; y = a + b₁x₁ + b₂x₂ + b₃x₃ + ⋯ … … … . + bₙxₙ the multiple regression equation for jute production is defined as; y = a + b₁x₁ + b₂x₂ + b₃x₃ + b₄x₄ + b₅x₅ + b₆x₆ + b₇x₇ + b₈x₈ where, y = b/c ratio a = y-intercept b = coefficient or slope for each variable x1 = sex of household x2 = highest education in family x3 = number of females economically active members x4 = machinery x5 = member of cooperatives x6 = loan for jute global sustainability research global scientific research 78 x7 = subsidy x8 = distance to nearest extension service preference ranking indexing was done in order to rank the problem by using the formula. i = σ sifi / n (miah, 1993) where, i= index score si = scale value of ith level fi = frequency of ith level n =total number of observations result and discussion descriptive statistical analysis of the variables table 11 shows the population characteristics of continuous variables with their mean and standard deviation. the study found the overall mean highest education of family to be 11.89 years with standard deviation 2.83. higher education among farmers helps to maximize yield per unit area by improving crop management practices. average of 1.38 number of females were found to be economically active in study area. furthermore, the study found nearest extension service center was 3.53 km far from household in average. table 1. population characteristics (continuous variables) variables mean std. deviation highest education of family (years) 11.89 2.83 number of economically active females

majority of households (87.50%) have male household head while only 12.50% of female household head. 74.20% of farmers had some kind of machineries which indicated 25.80% of farmers are deprived of any kind of machineries. very few farmers were member of cooperatives which might be due to low abundance of cooperatives or ineffective functions of cooperatives available there. meanwhile 68.30% of farmers received subsidy on seed and fertilizer reducing cost of production. 31.70% of farmers were found to be out of reach from any kind of subsidy. very few farmers were found to have drawn loan especially for jute production. global sustainability research global scientific research 79 table 2. population characteristics (categorical variables) variables category frequency sex of hh male 105

(97.5%) source: field survey 2024 cost structure of jute production the average total cost of jute production per ha per season was found to be nrs. 205891.23. among all the costs contributing to total cost in jute production, labor cost accounts the highest cost (36%) followed by processing cost (25%), machinery cost (15%), variable cost (12%) and land rent (12%). this indicates jute production is labor intensive mostly used during weeding and harvesting. machine introduced for harvesting of jute was rejected by farmers due to loss of jute sticks by breakage which is high value jute byproduct in study area. introducing effective machineries to lower human labor requirement is recommended. improvement in mechanization in jute farming will result in increased yield efficiency while minimizing labor requirement aligning with sustainable agriculture. dutta (2012) also found labor cost constitute highest cost (55%) followed by variable cost. within various variable costs, cost of fertilizer (urea, dap and mop) i.e. 48% was found highest followed by irrigation (31%), pesticide (12%), and seed (9%). this result is in line with result found by (dutta, 2012) who also reported cost of fertilizer highest followed by irrigation. figure 2 shows cost of pesticide is relatively lower which indicates farmers in study area use relatively lower quantity of pesticide. this highly contributes to sustainable agriculture. figure 1: pie-chart showing share of various cost in total cost land rent 12% total variable … machinery cost…labour cost 36% processing cost… global

study found gross return per ha land to be npr 313423.36 which includes return from both main product and by-product with gross margin npr 107532.13. gross margin was found to be low due to high cost of production but low price of jute. study found out bc ratio of jute production in study area to be 1.52. this implies with every 1-rupee investment 1.52 will be returned. therefore, jute production is found profitable as shown by positive gross margin and the bc ratio greater than one. this result is similar with result found by (islam, 2018) who also found bc ratio to be 1.52. table 3. economic

shows highest education of family in years was found positively significant with bc ratio at 5% level of significance with coefficient 0.03 which implies 1 years increase in highest education of

global sustainability research global scientific research 81 coefficient at 1% level of significance. this explains with increase in one female economically active member, bc ratio decreases by 6%. this is due to less efficiency of female as compared to male during various works on jute production increasing cost of production. presence of machinery had shown positive significant relation with bc ratio at 5% level of significance. similarly, subsidy had also shown positive significant relation with bc ratio at 5% level of significance with coefficient 0.20 which describes one unit increase in subsidy will increase bc ratio by 20%. providing subsidy to the farmers is seen to be highly effective in increasing profitability in jute production. distance to nearest extension service center was found to be affecting bc ratio negatively at 1% level of significance. increase in distance by 1 km decreases bc ratio by 31%. this is due to decrease in reach of farmers with extension service center in relation to subsidy and training with increase in distance. table 44 shows that the r2 value for jute is 0.32 which means that 32% variation in the gross return of jute was explained by the independent variables included in the model respectively. the values of adjusted r2 was found 0.27. this means that after considering the degrees of freedom (df), independent variables in the model still explained 27% of the variation in the gross return of jute. the f value for jute was found 6.58 which was highly significant at 1% level indicating the good fit of the model. table 4. factors

of retting pond (0.53) and unavailability of quality seed (0.53). so, the study suggests decreasing the cost of production which may be achieved by increasing subsidy and solving labor problem by technology intervention may result higher return in jute production. rashid (2022) also found high cost of production as primary problem followed by unavailability and high cost of labor. global

significant results in jute production in sunsari district, nepal. the study found jute production profitable as shown by benefit-cost ratio of 1.52 and positive gross margin. highest education of the family, machinery and subsidy were found to be positively significant with benefit-cost ratio. while, distance to nearest extension service center showed highly significant negative relation with benefit-cost ratio implying increasing distance lowers b/c ratio by a greater extent. high cost of production was found major problem in jute production and low price of jute as marketing problem. this study recommends providing subsidy and enhancing technology interventions is necessary to increase profitability in jute production. also providing fair price of jute to the farmers global sustainability research global scientific research 83 is necessary to stop jute growers from shifting towards other farming practices as shifting towards maize and sugarcane cultivation is seen more prevalent in sunsari district. increased income will enable farmers to afford nutritious food and help address hunger in long run. strengthening jute farming can enhance nepal’s export revenue which eventually contributes to national economic growth. jute being biodegradable and renewable, promoting jute usage aligns with responsible consumption practices. jute farming also reduces environmental impact and improve soil health. so, we can conclude that enhancing jute sector in nepal can reduce poverty, promote economic growth and improve environment. this describes jute farming as significant part of sustainable agriculture and sustainable development. declaration acknowledgment: we acknowledge institute of agriculture and animal science, paklihawa campus, nepal for providing required

process has increased since 1980s. nigeria has experienced uninterrupted democracy since 1999. this study carryout a test of good governance in nigeria using the six indicators of good governance used by world bank. specifically, the study determine the effect of voice and accountability, political stability and absence of violence and terrorism, government effectiveness, regulatory quality, rule of law and control of corruption on economic development in nigeria using per capita gdp as a proxy for economic development. inflation rate and oil price were included in the model in order to produce a robust model. annual data covering 1999 to 2022 were collected from world bank website. descriptive statistics were used to summarize data while autoregressive distributed lag model and bound tests were used to estimate relationship. findings revealed that the performance of governance in nigeria in all the six indicators during the period of study was weak. this consequently affect per capita income negatively both in the short-run and longrun. it was concluded that governance has negative effect on economic development in nigeria. it was recommended that the government should use worldwide indicators to conduct self-evaluation and carry out reforms that will help to improve governance in nigeria for the purpose of achieving development or improving the wellbeing of nigerians. keywords: good governance; development; democracy; world bank indicators; inflation rate; oil price introduction the origin of good governance can be traced to response to the weak governance in the african continent in 1980s. the world bank structural adjustment programme was unable to solve the economic challenges of the african countries. this made the world bank to conclude that that a part from economic factors, political factors and most especially bad governance signified by high level of corruption, absence of transparency and respect for human right orchestrated by the authoritative political system practiced in these countries was responsible for the economic failure of structural adjustment programme in the african countries (muhammad & rizwan, 2021). global sustainability research global scientific research 26 consequently, world bank identified good governance as prerequisite for qualification for development finance by developing countries. good governance and economic development have been associated. hope (2022), sees good governance as the force that boosts democracy, strengthen rule of law and public accountability and supports state institutions, thereby creating viable environments that supports economic development. similarly, mushbahu (2021) opined that the implementation of good governance practices is vital for the successful accomplishment of development programs in nigeria. good governance as observed by (bello, 2021) increases the economic welfare, while bad governance reduces the welfare of citizens through unfavourable or unfriendly policies and weak implementation of policies that are good. judging from the experience of developed nations around the world, good governance is connected to democracy and democracy associated with rise in economic welfare. however, the economic performance and welfare of nigerians have not improved as revealed by economic indices despite over twenty years of uninterrupted democracy. available statistics indicate that unemployment rate increased from 13.9% in 1999 to 32% in 2022, poverty rate rose from 6.6% in 1999 to 28.9% in 2022. inflation rate exhibited an upward trend rising from 6.6% in 1999 to 21.3% in 2022. the implication of these statistics is that the wellbeing of nigerians has fallen over the years despite the huge amount of natural and human the country is endowed with (samuel & chekwube, 2021; ibitomi et al., 2022). since 1996, world bank has developed six indicators used for measuring the performance of governments worldwide; the expectation is that strong governance performance, all things being equal, translates to development. these indicators include voice and accountability, government effectiveness, political stability and absence of violence and terrorism, regulatory quality, rule of law, control of corruption. the indicators are standardized data whose values range from -2.5 and 2.5. the mean of the data is zero. positive values or values greater than zero indicate strong governance performance while negative values signify weak performance. these indicators have been used to empirically carry out tests of good governance of countries, especially in developing countries of the world ( al-naser & hamdan, 2021). from the preceding, it can be deduced that good governance has been acknowledged as a prerequisite for economic development, especially in developing countries. also, indicators have been developed for measuring good governance performance among countries. however, there is dearth of empirical studies on good governance and economic development in nigeria, especially studies that utilized world bank governance indicators or variables as independent variables. moreover, the few available studies revealed mixed results, while some found positive relationship (ogi, eze & ene, 2023); others (richard, et. al. 2020) showed negative relationship between governance and economic performance. this implies that lack of consensus among these studies. consequently, this study is in furtherance of inconclusive state of empirical studies on governance and economic performance in nigeria. the focus of the study is to assess if there are significant relationships between wgis, namely voice and accountability, political stability and absence of violence and terrorism, government effectiveness, regulatory quality, rule of law and control of corruption and economic development. the remaining part of the paper is organized as follows: section two deals with literature review, section three presents the methodology of the study. results and discussion of findings are presented in section four while section five draws conclusions based on findings and gives policy recommendations that will help to improve governance and economic development in nigeria. literature review conceptual review according to world bank (2020), governance is the procedure through which institutional decisions are made and exercised in a country. similarly, alaaraj (2015) views good governance as a political and institutional system that global sustainability research global scientific research 27 promotes openness, accountability and public participation. adeboyega and arikewuyo (2020) describe good governance through outcomes. in this regard, they view good governance is related to the capacity of the government to deliver accurately public goods such as education, water, health, security, among others demanded by the citizens. lin (2014) defined good governance as strong capacity in the form of adequate economic power and strong political structure and provision of public services for promoting industrial and economic growth. the components of good governance have been grouped into six indicators. world bank (2021) describes the indicators as voice and accountability, political stability and absence of violence, government effectiveness, and regulatory quality, rule of law and control of corruption as indices used for measuring the performance of government worldwide and testing good governance. voice and accountability and political stability and absence of violence and terrorism the first two indicators cover the process of selection, monitoring and replacement of governments. voice and accountability being the first criterion any government must meet to be referred to as good governance refers to the degree of participation of the citizens in electing the people who govern them. it also captures freedom of expression, association and freedom of the press ( ibitomi & micah, 2021). the second indicator, political stability and absence of terrorism estimate the tendency of disruptions in the government through means that are not legal/constitutional or through violence which includes terrorism (hasan & hassan, 2021). government effectiveness and regulatory quality the effectiveness of government determines the level of the quality of policies formulated and implemented by the government and how credible government commitments towards its policies are (hasan & hassan, 2021). regulatory quality on the other hand, captures the capacity of the government in terms of improvements experienced by both public and private sectors as a result of the policies and regulations of the government. kaufmann, daniel in kraay, aart (2012) argued that good governance leads to economic development due to promotion of quality regulatory environment that that efficiently and effectively stimulates both the public and private sectors of the economy. rule of law and control of corruption the last two indicators of good governance relate to the respect of citizens and the state in terms of the institutions that guides economic and social interactions in the country. rule of law defines the indicator that measures the extent to which the citizens are aware and accept the rules and regulations of the country, the law enforcement agencies (police), courts and its connected associates. commenting on the importance of rule of law in an economy, burgess (2012) opined that a country that is governed by the rule of law experiences stability that definitely stimulates investment and establishment of enterprises by domestic and foreign investors due to the fact that they feel protected by fair implementation of laws by the judiciary system existing in a country(awad et al., 2021). the united nations defines corruption as acquisition of private gains through misuse or abuse of power. transparency international gives a more clear definition of corruption as the abuse of entrusted power for obtaining private gain (cleen foundation, 2010). furthermore, ogundiya (2019) gave a broad scope of corruption which covers behavious that include embezzlement, bribery, fraud, conflict of interests, rigging of elections, misappropriation, and conversion of public funds for personal gains, extortion, and manipulation of procurement processes, favouritism, among others. global sustainability research global scientific research 28 corruption has been recognized as one of the major factors that limits economic growth in many countries. in view of this, kaufmann (2019) contend that good governance involves the implementation of appropriate measures to curb or minimize corruption in order to achieve economic growth. xu (2019) also shares similar view about control of corruption and economic growth. according to him, good governance involves controlling of corruption through effective control of the country’s resources in order to promote economic growth. he stated further that failure to control corruption leads to waste of resources, inefficiency in the management of government revenue and reduction in economic growth. economic development bolarinwa (2013) citing mabogunje (1980) sees development as a dynamic process that involves quantitative growth and qualitative change, and must finally result in improvement in material welfare of the people. emmanuel (2005) and ibitomi, et al., (2022) advances besides increase in standard of living which involves increase in consumption, improved health, education and, development also means equal opportunities, political freedoom and civil liberties. undp definition of development centres on people and therefore uses three indicators which are longevity, knowledge and standard of living, collectively known as human development index to measure development. in quantitative terms, development is measured using gnp per capita/gdp per capita which is measures of per capita income. this measure determines the capacity of a country to increase its output at a rate that is greater than the rate at which the population growing (muo, 2006). theoretical review there is lack of consensus among available theories regarding the relationship between governance and wellbeing of the citizen. the conflict school maintains that democracy or governance creates consumption forces, instigates conflicts in distribution and discourages accumulation of capital. consequently, democracy hampers growth process in developing economies. however, empirical findings, in general have failed to provide empirical support to conflict school argument (przeworskiet, 2000). the next school which is also known as compatibility theoreticians postulate due to the presence of both fundamental human and political rights, democracy or governance creates the appropriate social environment that favours the development of the economy. consequently, governance influences growth positively (richard, 2020). the number three school is known as the skeptical school. this school opines that there is no relationship between governance and economic development. their claim as stated by knack (2013) is due to inconsistences that characterize old as well as new growth theories, which fail to provide theoretical explanation regarding variables that describe development in a good number of countries. solow growth model states that the long run growth or output of an economy is determined by the utilization of capital, labour and knowledge. the functional form of the model is illustrated in equation 1 below: y(t) = f (k (t), a(t) l(t) …………………………………………………………. (1) y represents output, k denotes capital, l is effective labour, a stands for knowledge while t represents time. a and l are placed in the model in a multiplicative way (romer, 1996). governance as an organization responsible for the management of the economy enters the model the policies formulated and implemented targeted towards increasing economic growth and standard of living of the populace. this means that proper implementation of public policies all things being equal, will lead to increase in output through its influence on capital and the effective labour factors (richard, et al, 2020). global sustainability research global scientific research 29 empirical review empirical studies across countries revealed in general that good governance have positive effect on economic development. ogili, eze and ene (2023) examined good governance and socio-economic development in enugu state, nigeria. specifically, the study investigated the effect of good governance on poverty reduction. descriptive survey design was adopted and data was collected through a structured questionnaire. z-test was used to test hypothesis. results showed that good governance significantly affect poverty reduction. richard, et al. (2020) carried out an empirical investigation on the impact of governance on economic wellbeing in nigeria. economic wellbeing was measured by per capita gdp growth. quarterly time series data covering 1996 to 2018 and autoregressive distributed lag model (ardl) bounds test method of estimation was adopted. findings revealed that the impact of governance on economic well-being both in the short-run and long-run were negative and significant. recuero and gonzales (2019) in their study found that institutional quality was positively related to economic development. the study also revealed that the direction of causality can change depending on the type of variables that signifying institutional quality. although economic development depends on legal institutional quality, improvement in institutional quality is also a key to economic development. the findings of this study is similar to similarly, habbyrimana and dushimayezu (2018) utilized determined the relationship between governance and economic growth in rwanda using correlational technique. findings showed that governance have positive relationship with economic growth. bayar (2016) and lahouij (2017) who found a positive relationship between good governance and economic development. hypotheses of the study h01: voice and accountability has no significant effect on economic development in nigeria. h02: political stability and absence of violence and terrorism on economic development in nigeria; h03 : there is no significant relationship between government effectiveness and economic development in nigeria. h04 : there is no significant relationship between regulatory quality and economic development in nigeria. h05 : rule of law has no significant effect on economic development in nigeria. h06 : control of corruption has no significant effect on economic development in nigeria. methodology this study adopted expo-facto research design. expo-factor research design finds out factors that are related to particular occurrence, condition, event or behaviuor through analysis of past or already existing data (kothari & gerg, 2014). due to availability of time series data on governance measured by world governance and data on economic development measured by per capita income, expo-facto design was adopted. the design was also adopted because according to lammers and badia (2005) expo-facto design does not permit the manipulation of the independent variable by the researcher. secondary source of data was utilized in this study. specifically, annual data covering 1999 to 2022 were collected from world bank official website. wgi data are in two forms which are standardized normal scores and percentile measures. wgi are standardized normal data ranging from -2.5 and 2.5. the mean of the data is zero. positive global sustainability research global scientific research 30 values or values greater than zero indicate strong governance performance while negative values signify weak performance. the magnitude of the index measures the degree of strength or weakness of governance. for instance, the closer the index is to -2.5, the weaker the governance and a value close to 2.5 indicate very strong governance. publication of wgis commenced in 1996 but the values for 1997, 1999 and 2001 are not available. the percentile measure on the other hand ranges from 0 to 100. the independent variables of the study are the six world bank indicators used to measure the measure good governance namely voice and accountability, government effectiveness, political stability and absence of violence and terrorism, regulatory quality, rule of law, control of corruption. the indicators were developed by two world bank researchers daniel kaufmann and aart kraay in 1999. the main purpose of the data was for international comparison and evaluation of general trend over time (world bank, 2023). these indicators have been used in to measure the quality of governance of countries and to predict economic growth, development or welfare. some of these studies include (recuero &gonzales, 2019; richard, 2020; senturk & ali, 2022). the dependent variable economic development was proxy by real per capita income. the choice of real capita income was based on the fact that it is one of the most common measure of economic development as indicated by previous empirical studies (siyakiya, 2017; glerghina, 2019, richard et al., 2020; senturk & ali, 2022). since economic development does not only depend on political factors but also on economic factors, macroeconomic factors were included in the model of the study as control variables. in order to minimize the error term in the model due to omission of variables, inflation rate and price of oil were included as control variables in the study. a variable is controlled when is effect on the dependent variable is kept constant. control variables are variables incorporated in multivariate analysis to detect spurious relationship. it is important to examine whether the relationship between dependent and independent variables continues after the effects of other variables affecting the dependent variables have been removed (mcchendon, 2002). the inclusion of inflation rate and oil price was based on the fact that literature review indicated that they were significant determinants of per capita income in nigeria ( oranefo, 2022). the first stage in regression analysis involves specification of model involves expressing the relationship between dependent variable and independent variables using mathematical equations (gujarati, 2006). multiple regression model was formulated for the study. the model of senturk and ali (2022) was adopted in the study with little modification. they regressed economic development (per capita income) as a linear function of quality governance (six world bank indicators of good governance), inflation rate. in this study, economic development (measured by per capita income) is modeled as a function of six worldwide governance indicators of world bank, inflation rate and oil price. the econometric model of the study is stated as: pit=𝛽0+𝛽1vac𝑡+𝛽2𝐺𝐸𝑡+𝛽3psavt𝑡+𝛽4rq𝑡+𝛽5rl𝑡+𝛽6coc𝑡+𝛽7infr𝑡+𝛽8𝑂𝐼𝐿p𝑡 +𝜀𝑖𝑡 where: pi = per capita income ( a measure of economic development), vac = voice and accountability, ge = government effectiveness, rq= regulatory quality, rl = rule of law, psavt =political stability and absence of violence and terrorism, coc = control of corruption, oilp = oil price (measured by annual average price of nigeria oil in dollars, per barrel in the world market), infr = inflation rate 𝜀𝑖𝑡 = error term that captures other determinants of economic development that were omitted in the model. 𝛽0 and 𝛽1 𝛽8 are regression parameters to be estimated. global sustainability research global scientific research 31 𝛽0 = intercept of the regression model 𝛽1 𝛽8 = are regression parameters that measure the effects of the independent variables on the dependent variable. based on economic theory, good governance is expected to positively affect economic development. therefore, the parameters 𝛽1 𝛽6 > 0. similarly, rise in price of oil in the world market is expected to influenced per capita income of the country positively, hence, 𝛽8 >0 while increase in inflation rate is expected to lead to a decrease in per capita income. therefore, 𝛽1 < 0. both descriptive statistics and econometric techniques of estimating relationships were adopted in the study. the descriptive statistics utilized in the study included mean, mode, median, minimum value, maximum value, standard deviation, coefficient of skewness and kurtosis. the econometric technique adopted were autoregressive distributed lag model (ardl) and bounds test developed by pesaran, shin and smith (2001) of measuring short-run and long-run relationship among economic variables. the choice of the technique was a result of the fact that the variables were a mixture of integration of order zero (i(0)) and integration of order one (i(1)). diagnostic tests carried on the residuals obtained from the estimated model in order to determine whether the assumptions of least square regression have been met. specifically, jarque-bera test was used to test the normality of the residuals, breusch –pagan godfrey tests determine the absence of heteroskedascity in the model while breusch – godfrey serial correlation lm test was used to check the absence of serial correlation in the model. moreover, cusum test was used to test the stability of the regression estimates. results data presentation and analysis table 1 presents the data on the dependent and independent variables of the study. specifically, the data relate to nigeria’s per capital gdp (pcgdp), world bank indicators of governance, inflation rate and oil price (oilp). descriptive statistic the data were summarized through descriptive measures namely the mean, median, maximum, minimum, standard deviation , skewness and coefficient of kurtosis presented in table 2. the mean of all the governance indicators are negative, indicating that weak governance during the period 1999 to 2022 in nigeria. however, worst performance is experience in terms of political stability and absence of violence and terrorism (-1.898). this is followed by control of corruption (-1.155), rule of law (-1.102) and government effectiveness (-1.041). governance in voice and accountability and regulatory quality are relatively higher with mean scores (-0.618) and (-0.900) respectively. average per capita income, inflation rate and average oil price were ($1909.41), 17.6% and $58.02 per barrel. the standard deviations of governance indicators ( 0.162, 0.187, 0.089, 0.162, 0.201 and 0.146) and inflation rate (3.117) are low indicating that the variables were stable during the period of study while the standard deviations ($763.542) and ($26.07) indicate that per capita income and oil price were characterized by fluctuations from 1999 to 2022. the coefficients of skewness (0.381, 0.528, 0.684 and 0.304) show that voice and accountability, political stability and absence of violence and terrorism, inflation rate and oil price are positively skewed, implying that their values are concentrated at left of their mean values while per capita income, government effectiveness, regulatory quality, rule of law and control of corruption are negatively skewed revealed by the coefficients of skewness (0.398, -0.408, -0.682 and -0.792) respectively. this indicates that their values are concentrated at the right of their global sustainability research global scientific research 32 mean values. the coefficient of kurtosis (3.485) shows that regulatory quality has a high peaked distribution since coefficient of kurtosis is greater than 3.0 while the coefficient of kurtosis (3.014) has a moderate peak (mesokurtic). the other variables have flat peak distributions (platykurtic) since their coefficients of kurtosis are less than 3.0. table 1: distribution of nigeria’s gdp per capita, world bank indicators of governance , inflation rate and oil

long-run on per capita income. the estimates are significant at 5% level of significance indicated by their probabilities (0.0185) and (0.044) respectively which are less than 0.05. consequently, the null hypothesis that voice and accountability has no significant effect on economic development was rejected. political stability and absence of violence and terrorism on the other hand has negative effect on per capital income in the short-run indicated by coefficient (-102.33) and probability (0.0178). however, in the long-run, the effect is positive shown by coefficient (25.95) and probability (0.0269). since the probabilities of the coefficients are less than 0.05, the null hypothesis that political stability and absence of violence and terrorism has no significant effect on economic

(0.0495) and (0.0297) are less than 0.05, indicating that the estimates are significant at 5%. this led to the rejection of the hypothesis that there is no significant relationship between government effectiveness and economic development. moreover, the coefficients of regulatory quality in the short-run and long-run(57.52) and (-29.659) reveal that regulatory quality has positive effect on per capita income in the short-run and negative effect in the long-run. however, the probabilities (0.9413) and (0.0391) indicate that the short-run coefficient is insignificant while the long-run estimate is significant at 5% level of significant. as a result of these, we reject the null hypothesis that there is no significant relationship between regulatory quality and economic development. furthermore, rule of law has significant negative effect on per capita income shown by the coefficient (-19.059) and probability (0.0069) while the effect in the long-run is positive and significant

average value of wgi for voice and accountability indicates weak governance. the regression output shows that voice and accountability have significant negative effect on per capita income in nigeria. this indicates that weak participation of the citizen in electing who govern them and poor state of freedom of press have resulted in decrease in per capita income and economic development. similarly, there is weak governance performance in terms of political stability, absence of violence and terrorism indicated by the mean score. the relationship between political stability, absence of violence and terrorism is negative in the short-run and positive in the long-run. the implies that government efforts towards prevention and control of violence and terrorism reduces per capita income in the short-run but increases it in the long-run. this also means that efforts towards controlling violence and terrorism by the government have not been sustainable. government effectiveness during the period of study is weak indicated by mean score (-1.041). the regression output reveals that government effectiveness has negative effect on per capita income both in the short-run and in the long-run. these show that the capacity of different regimes of governance over the years to formulate sound policies has been weak and when sound policies are formulated, they are usually poorly implemented. also, the quality of public service and regulation of public and private sectors has slow down economic growth and development instead of promoting it. moreover, the performance of governance in terms of regulatory quality is weak shown by the mean score (-0.900 ). regression output shows that regulatory quality has no significant effect on per capita income in the short-run global sustainability research global scientific research 38 but has significant negative effect in the long-run. this means that government regulations have not been favourable to private and public sectors of the economy, hence the decrease in per capita income. the mean value of wgi for nigeria from 1999 to 2022 is -1.102. this value shows that governance in nigeria is weak in terms of fair application of laws and respect of fundamental human rights. the effect on economic development is negative in the short-run but positive in the long-run. this means that by and large, the rule of law in nigeria in nigeria has promoted development notwithstanding the shortcomings in its application in the shortrun. furthermore, the mean score -2.34 reveals that government performance towards control of corruption is weak. this negatively affect the economic development in the short-run and has no significant has insignificant effect in the long-run. this means that failure of the government in nigeria to effectively combat corruption in all forms significantly hampered economic development. the findings of this study are supported by conclusion this study carried out a test of good governance in nigeria using world bank indicators of good governance using data spanning from 1999 to 2021. it was revealed that governance (voice and accountability, political stability and absence of terrorism, government effectiveness, regulatory quality, rule of law and control of corruption) and economic development had significant negative relationship. this means that governance in nigeria during the period of study reduced the wellbeing of nigerians significantly. the study showed that among the six governance variables, voice and accountability and control of corruption had the highest effect on economic development. these were followed by political stability and government effectiveness while regulatory quality and rule of law had the least effects on economic wellbeing. the findings of this study have both theoretical and practical implications. theoretically, it has shown that the nature of governance in a particular country can be tested through its impact on economic development. this means that the economic performance of a country depends among other factors on political factors, which includes governance. practically, this study provides the government at all levels, public officers and even the citizens with a scale that can be used to measure the performance of governance. the findings also implied that for nigeria to reverse the decline in economic development being experienced by the country as revealed by economic development indices, there is the need for strengthening the government and institutions in the country. this study is limited to 1999 to 2022. however, the relationship between two time series data is dynamic. this there is the possibility for the relationship between governance indicators and economic development in nigeria to change in the future. consequently, future related studies should focus on using more recent data. also, this study is only limited to nigeria. for comparison of findings, similar study should be replicated in other developing countries. moreover, using panel data helps to produce superior estimates than when only time series are used. future studies can test good governance using data that cut across countries over time. based on the conclusion of this study, the following recommendations have been suggested: i) the first priority of the government in promoting good governance in nigeria should be the promotion of political stability and ensuring absence of violence and terrorism that the country is currently facing. this can be done through adoption of peaceful approaches in resolving all forms of peaceful agitations from different sections of the country and fighting all forms of violence and terrorist actions towards disrupting democracy in the country. ii) the next priority should be the fighting all forms of corruption that has eaten deep into all fabrics of nigeria political, economic and social life. this can be done through public enlightenment of the citizens on the consequences of corruption via anti-corruption crusade, enactment of corruption laws prosecutions of offers. moreover, anti-corruption and law enforcement agencies should be reformed and empowered. global sustainability research global scientific research 39 iii) this should be followed by entrenching the rule of law in the country. this requires reforms in the judiciary and law enforcement agencies, especially the police and time-to time review of rules and regulations in order to so to foster justice, peace and protection of fundamental human rights. iv) urgent reforms tailored towards improving government effectiveness are also needed. improvements should be made in terms of the quality of government policies, public services, civil service, guaranteeing the independence of civil service from political forces and promoting credibility in terms of government commitment towards implementation of policies. moreover, in order to ensure that public policies are implemented adequately, the legislative arm of government should improve their oversight functions. v) this priority should be followed by urgent reforms aimed at improving the quality of regulation in the country. this can be achieved through adequate implementation of policies meant to improve the efficiency of the public and private sectors of the economy. vi) there is also the need to increase citizen’s voice and government should be made more accountable to the people. this can be achieved through promotion of freedom of the press and association in the country. vii) good governance also requires effective and efficient utilization of the country resources through diversifying the economy. this will reduce the over-reliance of the economy on revenue from crude oil that has made the country to be susceptible to fluctuations that characterized prices of oil in the world market. declaration acknowledgment: we want to appreciate

(2018), businesses can strategically navigate the utilization of developing digital technologies to enhance their competitive advantage and capitalize on chances for innovationdriven growth. this can be achieved through a combination of market, learning, and entrepreneurial orientations. there is an increasing urgency for smes to adopt creative approaches and digital production methods to sustain their competitive edge over the long term. in addition, the broader notion of industry 4.0 encompasses the utilization of various technologies related to decentralized data management within the cyber-physical system (cps). these technologies are being employed to facilitate modifications in the technical and production advancements of companies, ultimately resulting in enhanced business performance. furthermore, it can be argued that the phenomenon of digital transformation serves as both a catalyst and a precursor to the pursuit of sustainability. in this context, it is imperative for industrial enterprises to cultivate the necessary digital competencies to effectively address the interrelated economic, environmental, and social aspects of sustainability (gomez-trujillo & gonzalez-perez, 2021). hence, smes have the potential to utilize the functionalities of digital production techniques in order to facilitate a trajectory toward sustainability (telukdarie et al., 2022). digitalization plays a crucial role in achieving company sustainability by effectively addressing the fundamental principles of circular economy and sustainable development. following the covid-19 epidemic, there has been an increased significance placed on sustainability performance. smes experienced the greatest impact as a result of the pandemic, including heightened challenges stemming from disruptions to their business operations. according to rodrigues et al. (2021), it is possible that this has resulted in enduring liquidity challenges and had an impact on employment sustainability. furthermore, in light of the environmental issues faced by the market, companies are obligated to consider environmental sustainability while they engage in digital innovation (feroz et al., 2021). from a conceptual standpoint, sustainable development may be perceived as a strategic approach employed by businesses to address environmental challenges by fostering sustainable growth inside organizations. according to lu et al. (2020), there is a consensus among scholars that the adoption of sustainable development practices is increasingly recognized as a strategic approach for businesses, with the potential to contribute to longterm growth and stability. several studies in the extant literature have examined the performance of digitalization in smes (abdirad & krishnan, 2021; gonzález-varona et al., 2021; pfister and lehmann, 2021). in many instances, the attention was limited to a singular performance aspect, such as the economic or financial dimension, without considering the broader sustainability implications encompassing economic, social, and environmental factors. on the other hand, some studies have focused on the confluence between industry 4.0 and sustainability (rosa et al., 2020; beier et al., 2020) along with supply chain management and sustainability (birkel and müller, 2021). hence, there is a distinct void in the research on performance indicators for smes, which comprehensively incorporates digital, economic, social, and environmental dimensions. therefore, to fill up the existing literature gap, this research aims to examine the influence of digital transformation on the sustainable development of smes by using the systematic literature review methodology. this review analysis primarily examined three key areas: the technological aspects of digitalization, sustainability, and the business features of smes. this study provides valuable insights for academia, practitioners, and policymakers, aiming to assist smes in their efforts to adopt and implement sustainability-related practices. the study's findings would provide valuable insights for the effective implementation of policies aimed at fostering global sustainability research global scientific research 3 digitalization in smes, thereby contributing to sustainability. furthermore, this study makes a valuable contribution to the sustainable development goals (sdgs) outlined by the united nations (un), specifically sdg 1 (eradicating poverty), sdg 2 (eliminating hunger), sdg 3 (promoting good health and well-being), sdg 5 (achieving gender equality), sdg 8 (fostering decent work and economic growth), sdg 9 (advancing industry, innovation, and infrastructure), sdg 10 (reducing inequality), and sdg 12 (encouraging responsible consumption and production). methodology the current investigation utilized the systematic literature review methodology as recommended by raihan and bijoy (2023). the systematic literature review methodology is widely regarded as a reliable and robust approach (benita, 2021). systematic literature reviews offer a rigorous and replicable approach to investigating a developing field of research. by comprehensively examining existing literature, these reviews provide an overview of the current knowledge and facilitate the identification of crucial issues that need to be addressed, as well as potential areas for future research. a preliminary literature review was undertaken to identify relevant articles, validate the proposed concept, prevent duplication of previously addressed topics, and ensure the availability of an adequate number of articles for conducting a thorough analysis of the digitalization in smes in relation to sustainability. the relevant publications were comprehensively searched through four well-regarded academic databases, specifically google scholar, scopus, sciencedirect, and web of science, encompassing the period from 2000 to 2023. the keywords encompass three fundamental principles, specifically: smes, sustainability, and digitalization. the latter concepts encompass the terms "industry 4.0," "digital transformation," "automation," and "smart manufacturing." the present study exclusively utilized research publications that have completed a rigorous peer review process conducted by subject matter experts, hence ensuring the credibility and soundness of the results. the study encompassed an examination of both qualitative and quantitative secondary literature pertaining to the digitization and sustainability of smes. following this, the review implemented the process of citation tracking, which involves systematically monitoring all scholarly works that mention each of the papers included in the collection. the preliminary search yielded about one thousand documents. figure 1. the development of criteria for the selection of documents. global sustainability research global scientific research 4 the second search involved the inclusion of peer-reviewed papers, book chapters, and reports from government and international agencies. subsequently, the examination involved an analysis of the titles, keywords, and abstracts of the retrieved search outcomes in order to ascertain their level of relevance. for example, any publications that did not discuss the digitalization or sustainability of smes were excluded. the main rationales for the deletion of articles are their lack of relevance, duplication, inadequate textual content, or limited inclusion of abstracts. the preset exclusion criteria were implemented in order to mitigate the risk of any biases that may impact the results. figure 1 depicts the sequential evolution of the review criteria utilized in the process of selecting suitable documents. the literature review conducted in this study comprised a total of 61 unique scholarly papers. it is important to highlight that out of the 61 papers included in the qualitative synthesis, only those publications that offered pertinent information were referenced in the manuscript's bibliography. it indicates that specific articles were omitted from the reference list. figure 2 depicts the several stages of the systematic review technique employed in the present investigation. once the research topic had been selected, this study progressed by conducting a comprehensive search for pertinent articles, followed by an analysis and synthesis of various literature sources. subsequently, written materials were prepared for the purpose of article review. the synthesis phase involved gathering a diverse array of articles, which were then combined into conceptual analyses that were pertinent to the completed research. figure 2. the procedure of systematic review conducted by the study. results and discussion digitalization and technological innovations in smes digitalization and technological innovations within the framework of industry 4.0 and sustainability in smes are presented in figure 3. firms start digital transformation initiatives with a favorable adoption culture and a clear perspective of procedures. smes must recognize and grasp digital growth opportunities and implement projectbased learning to stay competitive in turbulent circumstances (north et al., 2019). mukhtar et al. (2020) showed how it affects smes' sales performance. others use a basic internet-enabled platform and an eco-sourcing tool based on model view control (mvc) architecture for smes to allow customers to pick and order vehicle products online (anthony, 2019). mekhum (2020) explored how supply chain cultural competence and technology adoption affect thai smes' performance. both aspects affect performance, but supply chain cultural capabilities are vital to technological adoption, according to the study. global sustainability research global scientific research 5 figure 3. the use of technological innovations within the framework of industry 4.0 in smes. the iot and iiot use embedded sensors in physical items and software and integration to provide real-time monitoring and data exchange over distributed networks. big data, iot, and smart factory setups help thai smes deploy it and perform well (haseeb et al., 2019). taiwanese textile smes demonstrate how iot-as-a-service (iotaas) creates smart value and sustains businesses (chen, 2019). cloud computing and iiot enable industry 4.0, which is smart technology (chonsawat & sopadang, 2020). smart industry 4.0, cloud computing, and cps enable technology strategies for cross-disciplinary value creation in taiwanese clothing smes (chen, 2020). dutta et al. (2020) also noted that iot, cloud computing, and big data are essential for indian manufacturing smes to digitize. smart self-monitoring, analysis, and reporting technology uses artificial intelligence, machine learning, and big data analysis to offer appropriate objects and agents cognitive awareness. automation/robotics adaption in smes is studied by ingaldi and ulewicz (2019). yazdi et al. (2018) demonstrate how smes can adopt a sustainable, intelligent smart manufacturing system using robotic systems with sensors. an intelligent material handling system for material distribution uses an agent-based algorithm for control architecture and a time study-based technique to evaluate equipment efficacy. oee research results optimize processes for sustainable productivity. overall equipment effectiveness (oee) helps smes reduce overtime, defer capital investments, reduce downtime/idle time, and increase operator performance. in addition, mittal et al. (2020) emphasized the importance of identifying manufacturing data accessible within the sme, readiness assessment, data-hierarchy phases, smart manufacturing knowledge among sme leadership and employees, development of the sme's smart manufacturing vision, and recognition of smart manufacturing techniques and procedures needed to achieve the firm's vision. global sustainability research global scientific research 6 furthermore, cloud computing lets users store and access information and applications online instead of on a hard disk. dutta et al. (2020) examined how indian manufacturing smes should use digital technologies for their functional domains. the survey found that indian smes prioritize industrialization—connecting machines and developing data analytics via iot, cloud, and big data. the survey stressed the need for real-time machine data and performance-based system design and improvement. as reported by trstenjak et al. (2020), smes' company size has a significant impact during development when using digital technology like cloud computing aided by fundamental infrastructure and complex planning methods to outperform traditional firms. a mechanism is regulated or controlled by computer algorithms in a cps system. müller et al. (2018) demonstrated how industry 4.0 improves supply chain stakeholders by sharing manufacturing data with vendors and consumers. broad product spectrum through industry 4.0 adoption (cps and ict) and value capture innovations through automated online customer relationship management platforms are prominent elements of the system. digitalization of manufacturing information addresses data, finance, and human resource shortages that hinder value development. müller (2019) found that industry 4.0 adoption affects smes. big data involves treating, analyzing, and extracting large, diverse, and fast-moving data. big data analytics (bda) mediated ‘project performance’ and nine aspects, which include top management, project information management focus on sustainability, buying green, green technology, social obligation, project operations, project difficulty, collaboration and exploratory learning, and achievement of goals (mangla et al., 2021). in the literature, the technology–organization–environment (toe) model and resource-based view are combined to model smes' bda adoption (maroufkhani et al., 2020). to use bda successfully in manufacturing smes, relative benefit, reliability, quantity, risk and uncertainty, trialability, visibility, support from executives, company readiness, competition, external support, and governmental oversight must be considered. ai allows computers or robots controlled by computers to perform human functions. basri (2020) explored how ai-assisted social media marketing (aismm) affects saudi arabian startups. innovative thinking, workplace connection, and lower turnover are aismm's key benefits. adoption increases client numbers and profits. effective business management and sme performance improved using aismm. 3d printing layers of plastics, composites, or biomaterials to make objects of various shapes, sizes, rigidities, and colors. coreynen et al. (2017) explored how digitization may promote manufacturer servitization and consumer value-added service. the study used ict and 3d printing to examine industrial, commercial, and value servitization. industrial and commercial servitization (based on ict for customer relationships, web app, and digital ‘marketplace’) offers advising, training, consulting, and online self-service management tools to let clients complete tasks themselves. value servitization (digital scanner items) helps organizations relieve customers faster. sustainability in the smes the environmental impact of manufacturing enterprises has spurred stricter laws to reduce or eliminate manufacturing procedures and other business dangers (raihan, 2023). circular economy techniques under industry 4.0 technologies are needed to address market-driven and environmental issues. for sustainable industrial development, job equity, gender equity, job losses, employee well-being, and growth and quality of life laws are also important. the sustainability dimension covers economic, social, and environmental issues that affect smes and sustainability in general. figure 4 presents the pillars of sustainability. global sustainability research global scientific research 7 figure 4. the three pillars of sustainability. economic sustainability small firms need innovation and other elements to survive. technology adoption, product introduction, and service opportunity acquisition lead to corporate sustainability and economic expansion (begum et al., 2020). chege et al. (2020) found that entrepreneurial innovativeness positively affects technology innovation and company performance in kenya. the study suggests new techniques to increase business performance with government support, promote technical externalities in the industry, and construct ict resource centers to improve sme performance. technologies enable new business structures and services (raihan et al. 2023b). chen (2019) describes textile smes’ integrated manufacturing, logistics, and marketing methods and value-creation techniques. iotaas value chains accomplish the former. integrating global value chains (gvcs) to co-create value for overseas customers achieves service orientation. sustainability via value-creation by capturing customer behavior and incorporating them into the business is key. digitalization enables manufacturing servitization (coreynen et al., 2017). servitization and expansion require managers to build digital assets and capabilities for customer-aligned procedures. chen et al. (2016) examined how an industry-specific web portal affects e-business organizational performance. service-oriented portal functions—portal maintenance, b2b, and cloud computing—significantly impact organizational performance. literature also examined how digital platforms and network capability affect smes’ financial performance (cenamor et al., 2019). digital platform networking capacity improves performance indirectly. sustainable expansion requires profitably using the platform’s capabilities and connecting with the right business orientation. material, energy, labor, equipment, and fixtures affect a manufacturing firm’s sustainability. case studies in the literature assess sustainability issues for a us sme transitioning from shielded metal arc welding to robotic gas metal arc welding (epping & zhang, 2018). results showed sme benefits from robotic implementation’s economic expenses. global sustainability research global scientific research 8 environmental sustainability smes increase greenhouse gas emissions like other enterprises; thus they must take corrective measures. a green company strategy and smart industrial efforts are needed in the current climate. the smart factory concept requires firms to focus on cost calculation, quantitative benefit analysis, and corporate social responsibility (csr) activities to create a green corporate image and add an environmental dimension (lu et al., 2020). chen (2020) used “green manufacturing concepts” to create a strategic plan for integrating textile manufacturers and cultural content producers into gvc. the sustainability assessment process identifies the firm’s weaknesses and the best way toward sustainable growth. tools to quantify product or process environmental effects were investigated by epping and zhang (2018). life cycle assessment (lca) to detect and quantify material flows, energy needs, and environmental emissions; public goods tool to display public goods from different farming arrangements in a straightforward, quantitative, and accessible way. ecological footprint evaluation of methods based on ecological capacity via sustainable process index; carbon footprint calculators-carbon produced by agricultural companies and fixed to soil and biomass on land; multi-criteria instruments, sustainability assessment of food and agriculture systems; global reporting initiative tools. kassem and trenz (2020) propose cost-effective, easy, efficient, automated, comprehensive, and simplified sustainability assessment solutions. czech brewers are testing webris (web information system for corporate performance evaluation and sustainability reporting), a basic automated information system. sustainability value added (sva) is an effective sustainability evaluation method. firms must identify economic, environmental, social, and governance elements affecting sustainability (raihan & tuspekova, 2022). webris compares firms’ computed sva to discover weaknesses. social sustainability llinas and abad (2020) used spanish smes to demonstrate how high-performance people management techniques boost business efficiency through innovation. people management methods significantly correlated with productivity and innovation, with industry 4.0 technology as a key facilitator. people management is a top priority for industry 4.0 firms, according to the survey. carroll's pyramid approach can improve smes' organizational performance and sustainability (lu et al., 2020). business success depends on giving stakeholders social, logical, and transitional benefits as the organization transforms. in an age of technology, smes must implement technology efficiently and effectively, especially since automation may reduce and replace blue-collar employment. technology adoption reduces manufacturing jobs by automating boring tasks. müller and voigt (2018) advocate training and retraining staff during a company's transformation. this gives workers confidence and well-being. haseeb et al. (2019) found that firms have it but seldom implement it, which hurts business performance. epping and zhang (2018) used social life cycle assessment (slca) to evaluate the social and socioeconomic implications of robotics adoption. manufacturing affects earnings and remuneration, safety, personal and technical advancement, and social interaction. fair wages and on-duty health and safety were emphasized by epping and zhang (2018). through the transition from a ‘business-as-usual’ plan to a long-term approach for the digitalization of common resources, networking smes and other stakeholders (such as academic institutions, rivals, and customers) foster social sustainability. zoppelletto et al. (2020) examined how a digital transformation strategy (dts) might improve network organizations' business network commons generation/regeneration. digital resources drove bnc revitalization, with dts supporting quality and social responsibility. the study added to the literature on digitalization's social and economic benefits. global sustainability research global scientific research 9 business characteristics of smes an organization's ability to evaluate its internal and external surroundings and respond quickly to market changes defines its sustainability. a firm's aptitude to adapt to these shifts is determined by excellent leadership and management. the organization structure, strategy, and resource base enable customer value delivery. this study addressed company strategy and management, organizational structure, culture, skills and qualifications, and firmspecific leadership as the key business characteristics of smes (figure 5). with an emphasis on innovation, industry 4.0 interventions have substantially decreased business model lifecycles. building a new business model or adapting an existing one to market demands requires innovation. innovation in firms and the business environment boosts technology activities (pucihar et al., 2019). to appreciate industry 4.0 technologies as important facilitators, smes require new technology adoption policy measures. somohanorodríguez et al. (2020) indicated that smes' innovation initiatives positively impact industry 4.0 digital enablers. the selection and use of the best technology are typically inadequate in smes. using a maturity-level-based assessment tool is necessary. rauch et al. (2020) developed and tested a maturity level-based assessment tool on 17 enterprises as well as 42 industry 4.0 concepts and a plan to help smes introduce the most promising ones. additionally, jiwangkura et al. (2020) showed multi-dimensional iiot deployment methodologies with innovative hci for smes in manufacturing. results show corporations can empower using iiot. an organization that uses it, system integration, and automated business processes for gathering data with quality delivery and management would handle competition well (pomffyová et al., 2017). according to prause (2019), market uncertainty drives industry 4.0 technology and process adoption more than internal forces. figure 5. the key business characteristics of smes. global sustainability research global scientific research 10 industry 4.0 helps smes perform sustainably despite technology adoption obstacles. haseeb et al., (2019) validated this idea by showing that organizational structure and procedure improve industry 4.0 and it implementation in thailand. business model, strategy, digitalization, leadership, organizational structure, and supply chain management assist smes' industry 4.0 readiness indicators under organizational resilience. industry 4.0 ideas are also supported by a culture of communication between interdisciplinary departments and workers, management, and organization techniques. smes that can adjust to environmental changes must be part of the corporate culture. according to mekhum (2020), “organizational culture requires a significant connection with the objectives of an organization since it has a close connection with business performance”. dewi et al. (2020) showed that adaptable capability boosts creativity and competitiveness. innovation now mediates adaptive capabilities and competitive benefits. note that digitization does not directly predict corporate performance without a spirit of entrepreneurship. in the global market, innovation, risk-taking, and initiative are essential (raihan et al., 2022). chen (2020) found that business partner trust can improve a value creation approach for industry 4.0 adoption to reach gvc. irimiás and mitev (2020) surveyed 270 smes and major enterprises in hungary to determine how they view change management, digitization, business performance, and sustainability. change management improves digital maturity and business performance, but managers think going green is unprofitable. managers sometimes confuse business resource planning adoption for strategic benefits like competitive advantage and organizational performance (jayeola et al., 2020). this will combat firm change resistance. to profit from bda adoption, smes need a resilient data-driven culture and infrastructures (maroufkhani et al., 2020). llinas and abad (2020) found that high-performance people management approaches to boost productivity in industry 4.0. sme innovation, productivity, and growth depend on hr management, credentials, and skills. sariwulan et al. (2020) examined how digital literacy, economic literacy, and entrepreneurial abilities affect garment cluster smes in the tourism industry. the study demonstrated positive relationships between digital literacy, entrepreneurial skills, economic literacy, and performance. digital literacy helps businesses grow through marketing networks providing performance. bertello et al. (2021) found that bda capabilities are more important than bda infrastructure and internationalization for productivity. cenamor et al. (2019) examined the financial performance of smes using digital platforms indirectly via network capabilities. the study reported that increased platform capabilities boost innovation. chinakidzwa and phiri (2020) found that digital strategy creation and execution competence drive sme sales growth, market share, and profitability. in addition, kulathunga et al. (2020) examined how techno-finance literacy and enterprise risk management (erm) apps affect sme performance. the study found that technological understanding and financial literacy improve business efficiency and erm practices, with better financial literacy enabling erm. using the technological, organizational, and environmental (toe) paradigm, alraja et al. (2021) examined leadership and digital transformation in omani smes. according to the study, leaders must develop plans that offer organizational and technological support for an easy transformation to boost capacities and worldwide competitiveness. the change will reveal criteria for engineers and managers. the customer-product-processresource (cppr 4.0) model by martínez-olvera and mora-vargas (2019) outlines the value proposition-creationcapture cycle in an industry 4.0 environment for manufacturing organizations, considering customer, product, process, and resource perspectives. the study's system dynamics model could be substituted with a discrete-event simulation for what-if scenario testing to balance cost structure and revenue stream. leaders and managers can use these frameworks for decision-making and forecasting. global sustainability research global scientific research 11 conclusions the objective of this study is to examine the effects of digital transformation on the sustainable development of smes. the systematic literature review approach has facilitated the qualitative synthesis of documents, leading to the discovery of various insights. one notable finding is the significant influence of organizational culture on the adoption of technology and subsequent data management, which serves as the fundamental basis for smes to undergo digital transformation. sustainability projects facilitated by digital technology are made possible by the implementation of inventive solutions. the situation necessitates the implementation of a sustainability assessment in order to determine the necessary parameters and aid managers or leaders in efficiently and effectively transforming smes. the optimization of organizational procedures and structures is crucial as it has a direct influence on the successful application of digital technologies. furthermore, the choice of technology is contingent upon the digital orientation that is embraced. the prioritization of management requirements over technological sophistication itself becomes crucial in the process of transformation, as it encompasses innovativeness and high performance. it is evident that advanced technologies, including robotics, provide comparable performance to ordinary ict resources. this observation suggests that creativity, talent, and management play crucial roles alongside technological sophistication. a compilation of potential avenues for future research has been derived from the comprehensive review. recommendations and future research directions this review ought to be expanded by collecting empirical data (from surveys and interviews) on how smes might digitally transition for sustainability. such studies should define technology goals (immediate, medium, and longterm) and build technology roadmaps to better understand how smes may use digital technologies to achieve sustainability. digital transformation and industry 4.0 use iot, cps, big data, and ai/ml. thus, it is necessary to determine which technologies can best influence sme performance. further research is needed on smes' digital transformation cost-benefit analyses. understanding the benefits of digitalization and how certain technologies might boost competitiveness and productivity is also needed. this knowledge can inform smes' digital transformation initiatives. smes traditionally prioritize economic sustainability, but to achieve sustainability, they must also address environmental and social issues. to achieve sustainable development along all three dimensions, smes must understand how to offset trade-offs across these three orientations. sustainability evaluation must be cost-effective, efficient, automated, comprehensive, and systemic to pursue green manufacturing concepts and a go-green strategy. smes can be pressured while pursuing this goal, hence support methods are needed. thus, sme assistance mechanisms need additional study. sme economic and environmental sustainability are well understood in sustainable development. social sustainability studies, including how smes might maximize social impact in emerging economies, are underrecognized. this crucial area needs more research. understanding how sme business models incorporate technology maturity, organizational framework and procedure, leadership capabilities, digital skills, and knowledge is crucial. smes must establish new business models that balance digital transformation costs and sustainable development rewards. technology-driven innovation with value-creation methods helps smes engage customers, suppliers, and stakeholders, boosting market activity. this requires stakeholder confidence via data sharing with ip protection, but standard rules and legislation must be explored. these rules and regulations need more research on their nature and ideal configuration. additionally, smes require the skills and knowledge to achieve sustainable development. education and training global sustainability research global scientific research 12 should support this requirement and focus on leadership skills. further research is needed to establish support mechanisms to help smes digitally transform for sustainable development. limitations of the study this study contains several limitations. first, the literature search strategies may exclude publications on specific aspects of corporate sustainability, such as corruption, tax behavior, or biodiversity, without explicitly linking them to sustainability. to improve the existing knowledge, more research could shed light on such subjects. second, this review analysis only used four databases, potentially eliminating insights on sme sustainability from conference papers, books, book chapters, and journals indexed in other databases. third, his review assessment included articles published in english-language. however, numerous french and portuguese studies are pertinent to this study. future studies may examine multilingual literature. fourth, this study’s sample consists of articles published between 2000 and 2023. future research on digitization and sustainability in smes could replicate this study by using a wide range of sample sizes. declaration acknowledgment: the author expresses gratitude to professor dr. tapan sarkar for his encouragement in writing this

wood; conservation; circular economy; sustainability; european union introduction the european union's economic resurgence from the great recession has not been accompanied by widespread and consistent expansion across the continent. an underlying uncertainty regarding future socioeconomic dynamics is outlined by the possessions of the epidemic catastrophe and, more lately, the geo-political war on the eastern tip of the region, with corresponding energy issues (martinho, 2022; raihan & tuspekova, 2022a; zakeri et al., 2022). the potential to shift toward a completely circular economy and an extremely sustainable development pathway is hampered in many cases by this vagueness, which has large but similarly varied implications on the distinct production segments (raihan & tuspekova, 2023a; anghel & jones, 2023; raihan et al., 2023a). even before the pandemic, regional and local markets were mostly responsible for managing these difficulties, often with great effectiveness (allam et al., 2022; raihan et al., 2022a; voumik et al., 2023a). global and local climate change have made certain supply chains especially vulnerable to ecological, territorial, and community concerns (nocentini et al., 2017; ghadge et al., 2020; raihan & voumik, 2022a; raihan et al., 2022b; isfat & global sustainability research global scientific research 73 raihan, 2022; voumik et al., 2022; ghosh et al., 2023; raihan & himu, 2023; sultana et al., 2023; voumik et al., 2023b) due to their exposure to continuous transformations reflecting the ecological transition (raihan et al., 2022c). simultaneously, it was shown that forest ecosystems are ever more vulnerable to hazards like extreme climatic events, fire, pathological epidemics, and general anthropological actions, all of which have significant (yet poorly quantified) economic impacts (corona, 2019; pecchi et al., 2019; ali et al., 2022; raihan & tuspekova, 2023b). how these problems are dealt with by forest management will have far-reaching consequences for human health, biodiversity, productivity (economic and ecological), and the capability of forest ecologies to withstand external distresses (begum et al., 2020; raihan & tuspekova, 2022b; raihan et al., 2023b). forests provide numerous ecological services that are important to civilization and social interests (raihan et al., 2018; angelstam et al., 2019; raihan et al., 2018; doimo et al., 2020; newton et al., 2020; raihan et al., 2021a; raihan et al., 2023c), and not just wood stuff (raihan et al., 2021b; raihan & tuspekova, 2022c; raihan et al., 2023d). businesses and society as a whole benefit from a focus on environmental sustainability since it lowers risk, encourages innovation and entrepreneurship, and makes supply chains more competitive (lazdinis et al., 2019; aszalós et al., 2022; raihan & tuspekova, 2022d; raihan et al., 2022d). the international panel on climate change (ipcc) has reaffirmed the value of forests and associated prolific segments, showing how co2 emissions can be cut by as much as a third using only environmentally friendly methods (raihan & tuspekova, 2022e; raihan & voumik, 2022a). that’s why it’s important to support companies and management techniques that strengthen interdependent supply chains and forest ecosystems (masson-delmotte et al., 2021; raihan & tuspekova, 2022f). europe’s forestry industry serves many purposes, from creating jobs and boosting rural economies to consolidating (at least indirectly) the recreational pleasures associated with mature forests (corona et al., 2016). spending time in woods has been shown time and over again to be beneficial for stress reduction, mood elevation, and even health recovery (grilli & sacchelli, 2020). lawbreakers, psychiatric patients, youngsters emotionally troubled, and people with psychological healthiness concerns are just some of the populations who have been the focus of numerous research that have investigated the efficacy of forest-related therapy lineups in improving their condition (shin et al., 2010; raihan & tuspekova, 2022g). forests play an important role in delivering ecosystem facilities (raihan & tuspekova, 2022h), including an extensive array of recreational and tourism events like picnicking, hiking, and biking, and this fact has been widely disseminated thanks to numerous worldwide enterprises, such as the european edges cost act e39. thus, there has been a push to acknowledge forests’ potential as places for recreation, stress reduction, and relaxation (grilli & sacchelli, 2020). while forestry has obvious economic benefits, wood also has major manufacturing and energy uses, the latter of which is expected to rise in the current geopolitical context (zakeri et al., 2022; skyrman, 2022). given our nation’s rich forest history, this appears to be a beneficial development; but it is also seen negatively because it may reduce demand for wood used in higher-value manufacturing processes. meanwhile, a structural issue of reliance on foreign supply plagues businesses, particularly furniture industries (santos et al., 2019; ghadge et al., 2020). data from authoritative sources suggests, albeit in a roundabout way, that the inherent vulnerability of forest formations is becoming more apparent and increasingly accompanying with the financial and communal dynamics of confined regions, demonstrating a foundation of instability and ambiguity and diminishing the probable flexibility of whole areas to worldwide changes (macdicken, 2015). when the adjacent circumstances (accessibility, absorptivity to modernization, networking, trade openness) are unfavorable, doing business can be extremely challenging, especially in economically underprivileged circumstances like national and peripheral zones in the ancient landmass (bowditch et al., 2020). the present article draws on a literature analysis to examine the changing face of european forestry and to outline the environmental and economic complexities that define the forest industry. significant communal insinuations for resident regions familiarizing themselves with ongoing ecological alteration, from global warming to topography modifications, stem from the widespread usage of a significant natural resource like wood (garbarino et al., 2020; raihan et al., 2022e). in line with previous research, this review article recommends the significance of the technological-financial attribute of forestry in the sustainable development routes of regions and counties (hazarika et al., 2019), which influences short-range economic dynamics, sector expansion possibilities, supply chain organization, interconnectedness among corporations, and financing approaches in general. simultaneously, this review’s contribution provides global sustainability research global scientific research 74 evidence that simplistic interpretations based on purely ‘technical’ points of view cannot capture the nuances of forestry and its inherent interaction with additional economic segments and ecological challenges. this research, on the other hand, lends credence to the idea that including a ‘holistic’ interpretation of forestry into sustainable development pathways across spatial scales would be beneficial. only by defining future avenues of theoretical research and empirical examination it might be possible to achieve the social, environmental, and economic goals of forestry that are essential to its success. this review article is structured as follows to answer the important query of sustainable development in every manufacturing segment with pertinent implications on the environmental quality. in the second section, this article presents a quick look at the shifting landscape of european forests. the consequences of forestry on the natural world are the subject of the third section. the fourth section summarizes authorized statistics and introduces an ephemeral examination of the prolific interconnectedness amid the forestry sector and the furniture manufacturing in europe, outlining the financial utilization of forest resources besides the supply chain of wood-furniture. the sustainability-focused framework of european forest policy and its most recent developments are summed up in the fifth section. the review article concludes with an exposed discussion of the key questions at play in the debate over forestry’s environmental and economic influence in developed markets, potentially differentiating between central and peripheral locations, where forestry signifies a pertinent added value in country structures that might be better adjusted with the feature of ecological reinforcement. recent dynamics in european forest resources deforestation is increasing at a degree of yearly 10 million ha (fao, 2020), while forest area is decreasing at an alarming rate of 4.7 million ha annually on average. brazil, congo, indonesia, tanzania, angola, paraguay, cambodia, myanmar, mozambique, and bolivia are among the nations with the biggest net (year average) forest cover losses throughout the last decade (fao, 2020). however, over the last 30 years, there has been a greater recognition of the significance of forest conservation measures, leading to an increase of nearly 200 million hectares of protected forest areas from 1990 to 2020 (fao, 2020). european union (eu) land and about 6% of marine zones (encompassing roughly 850,000 km2) are protected by the natura 2000 network, one of the newest projects introduced and the biggest coordinated network of protected sites in the eu. this system was developed in response to the habitats directive and the birds directive with the goals of protecting endangered species in their natural environments and ensuring the continued functioning of ecosystems for future generations (evans, 2012). establishment of forest cover, specifically in peripheral regions of developed nations, is a feature of advanced economies (pagnutti et al., 2013), which are consistent with trends observed in europe’s forests. one of the most significant shifts in land use over the past two centuries in europe was the increase in forest cover, which was spurred on by widespread reforestation efforts. however, the acceleration of technical improvements that intensified the farming systems on reduced ranges is also a result of rural emigration; these changes have freed up land-dwelling for the recolonization of forests, especially on unrestrained and formerly farmed land (frei et al., 2020; santarsiero et al., 2023). western european forest cover grew by over 30 percent in the half-century after wwii (charru et al., 2017). central-eastern and southern europe saw slower rates of growth (20% and 16%) compared to northern europe, where forests were before now the dominant land covering by the middle of the previous century. still, forest area has increased practically everywhere up to now, though it has slowed down significantly meanwhile the immediate 1990s. western europe is the only region where this trend has reversed. there will be 10.2 million hectares more of forest in europe by 2020 than there were in 1990. about 45% of the land cover of the european union (eu) was comprised by forests and woodlands in 2020 (excluding inland seas), making the eu home to about 5 percent of the earth’s total forest acreage (forest europe, 2020). as an illustration of long-term tendencies, less than 0.4% and 0.3% of land conversions in europe have been accounted for by afforestation and deforestation, respectively, in current ages (forest europe, 2020). sweden’s forest assets are predicted at 30.3 million hectares in 2020 (purwestri et al., 2020), making it europe’s largest forest area. while the only other member state was finland with a concentration of over 20 million hectares, spain recorded the second-largest area at 28 million hectares (palátová et al., 2022). following closely behind was france, with 18.1 million hectares of forest, followed by italy and germany, each with roughly 11 million ha of forest (cook, 2020). in 2020, half of the territory of the 8 member countries will be covered by forests. slovenia (62.8%), finland (76.2%), and sweden global sustainability research global scientific research 75 (74.5%) had the greatest rates in comparison to their respective national areas. forests cover between 50 and 60 percent of the land in estonia, latvia, spain, portugal, and greece, but they cover between 11 and 16 percent in the netherlands, ireland, and denmark, respectively. only sweden saw a decline in forest cover between 1990 and 2020 (-0.4%), while three mediterranean european nations (italy, croatia, and cyprus) saw increases of more than 8% during the same time period (forest europe, 2020; kumar et al., 2021). the effects of human activity have been profound on the structure and content of european forests. only 26 percent of wild species and 15 percent of forest ecosystems gain a positive conservation category (eea, 2015). in addition to sequestering 13 percent of europe’s emissions, housing an overriding portion of terrestrial biodiversity, plus making important contributions to climate change mitigation, it has been predicted that forests eliminate roughly 430 million tons of atmospheric co2 annually (nabuurs et al., 2018; raihan & said, 2022). in 2050, cities will be home to roughly 84% of europe’s population (pesaresi et al., 2016), have major effects on air and soil conditions and, by extension, the health of people across europe, particularly the young and the old. most ecoregions in europe can expect an upsurge in temperatures and a decrease in precipitation in the future, and this will occur at a more rapid rate compared to the remainder of the globe due to the impact of an inevitable change in the composition of the earth’s atmosphere. urban forestation initiatives, which involve an enormous rise in planting to improve the microclimate and quality of air in urban areas by capturing carbon dioxide and protecting the soil coming from the sun and rain, are one of the most common ways of coping with the impacts of global warming on cities (escobedo et al., 2019; raihan et al., 2022f). figure 1 presents the forest dynamics components under european classifications. figure 1. forest dynamics under european classifications (ivanova et al., 2022). global sustainability research global scientific research 76 vital ecosystem facilities and goods are provided by all urban natural areas, including a wide range of green covers (forests, botanical gardens, urban parks, street tree, plantations, and cemeteries; edifice swathe rejuvenation is a relatively new addition to this list) (escobedo et al., 2011). these include, but are not limited to, the maintenance of habitat attributes, the control of air, soil, water, and climate, besides the provision of food and water (raihan et al., 2023e). in addition, urban forests, particularly in developed states, may show a pivotal part in resolving resource struggles as a hallmark of modern globalization (hayter & clapp, 2020) that arise from the tension between manufacturing urgencies and environmental and social needs (whiteman et al., 2015; raihan et al., 2022g; raihan et al., 2023f). finally, no authorized map casing vast spatial levels can be regarded acceptable in directing the issue of forest distribution in europe (yousefpour et al., 2018). this question can be answered more precisely with the use of official statistics (such as fine-scale agricultural censuses and geo-spatial statistics from forest inventories) and land-use maps. influence of forestry on the environment inadequate forest management has the potential to jeopardize or even destroy forest resources and services. still, forestry practices are a major reason why forest habitats and species are in a poor conservation position (cutino et al., 2018; raihan et al., 2022h; raihan, 2023a). in this regard, forestry techniques across europe range from total lack of managing caused by abandonment or protectionist policies to be restricted management or intensive short rotation forestry designed to provide electricity biomass (pergola et al., 2022). however, management regimes that mimic natural disturbances can have a significant impact on stand structure, potentially leading to an increase in biodiversity over time while also reducing the rate at which forests undergo change (kuuluvainen et al., 2021; raihan, 2023b). although forestry may have an effect on plant diversity and wildlife, it is generally less severe than agriculture practices due to the very inadequate usage of fertilizers, which are typically lone used for weeding prior to reforestation campaigns or to indulgence conifer over broad-leafed regeneration (muys et al., 2022). since the use of biocides is extremely rare in the forestry industry, managed forests employ these products at a fraction of the rate and with far less frequency than agricultural systems (freer-smith et al., 2019; raihan, 2023c). the absence of tree species diversity, variation of tree phase, and unusual ecosystems like deadwood all contribute to managed forests having substantially lower biodiversity than natural forests (freer-smith et al., 2019; raihan, 2023d). given that stand age is a critical factor in the delivery of forest ecosystem services (sutherland et al., 2016), it may be unfair to label it as yet another “victim” of modern forestry practices like clearcutting of mediumaged besides old stands, which may reduce the quantity and quality of forest functions (jonsson et al., 2020; raihan, 2023e). old growth forests are threatened by intensive forestry practices, which can lead to their temporary extinction (dellasala et al., 2022). unfortunately, the loss of biomass from old-growth and primary forests in europe is continuing (svensson et al., 2019), primarily for economic reasons, leading to a typical outline of forest degradation, comprising of the transformation of these surroundings into secondary forests (angelstam & manton, 2021) and the extinction of individual species dependent on deadwood or old trees (raihan, 2023f). finally, forest utilization practices (such as extracting non-timber goods, timber harvesting, converting natural forests to plantations, and roads and amenities construction) and the slow introduction of plant species for merchantable agroforestry practices can all contribute to the foreign invasive species introduction and proliferation (ohimain, 2022). figure 2 presents the environmental services and economic opportunities provided by the forests. economic utilization of forest resources and wood furniture supply chain even if the total forest area in europe has remained relatively unchanged over time, this does not rule out the possibility of significant changes in the region’s forests. both human activities, especially the removal of biomass; and ecological maturity or other natural processes affect forest ecosystems (jaafar et al., 2020). statistics from across the country supply data reflecting the depiction of the light and shade in the commercial utilization of forests, which may be deemed intensive only in particular regional scenarios, despite a general tendency toward broadening and asset under-use at the local level (canadas & novais, 2014; raihan, 2023g). in fact, the average rate of forest usage (comparison of yearly volume lost versus yearly volume expansion of the remaining forest stock) across europe in recent years has stayed far below 1 (eir, 2018). global sustainability research global scientific research 77 this suggests that there are prospects for larger harvests in various contexts and that, while timber production has differed by nation, it has persisted extremely sustainably. this presumption is based on a global scale analysis that compares national levels of gdp growth and consumer spending using varying data quality benchmarks. some protected areas may not be viable if intensive logging is practiced on a regional scale (bösch, 2021). figure 2. environmental services and economic opportunities provided by the forests (fao, 2023). in some fractions of europe (specifically in confined contexts in eastern europe), overexploitation of forest resources may still be an issue today (bălăcescu, 2020). even at a finer spatial scale (prefectures, municipalities), the situation is likely to get more convoluted. however, even in the most economically developed countries, accessible data rarely allows for such precision. in 2020, the total volume of timber in eu-27 woods was roughly 27.6 billion cubic meters (bcm). germany and sweden have the largest timber stocks amongst eu countries, totaling about 3.7 bcm (13.3 percent of the total eu-27). other countries with sizable wood reserves include france (3.1 bcm and 11.1 percent), poland (2.7 bcm and 9.9 percent), finland (2.5 bcm and 8.5 percent), and romania global sustainability research global scientific research 78 (2.4 bcm and 8.5 percent) (forest europe, 2020). in spite of the challenges it faces, these numbers show that europe’s forestry industry has room to grow economically and portray a positive function in the future of many countryside regions (perunová & zimmermannová, 2022). the conventional forestry segment (forest management, harvesting, sawmilling, forest products and processing) in the eu employs over 2 million people and generates a gross added value of more than €100 million per year (tiebel et al., 2022). there are nearly 16 million private forest proprietors in the eu. forests can be held by anybody from individual families to governments to investors in huge estates (weiss et al., 2019; raihan, 2023h). yet over 60% of the forest area is owned privately (maesano et al., 2018). by combining agricultural and forestry output, many farms provide economic diversification (ficko et al., 2019). in 2017, the eu-27’s forestry sector contributed 0.2% of the eu’s entire gdp with a gross value added of 26.2 billion euros, a rise of 1.5% from the previous year. finland, sweden, france, and germany accounted for just over 50% of the total value added. they were all worth between €3.2 billion and €3.8 billion. about half of the eu-27 countries had forestry account for gross value added below 0.3% of total. in contrast to the european average of 1.0%, this proportion was higher in finland (1.9%), latvia (1.7%), and estonia (1.2%) (forest europe, 2020). nearly half a million europeans have found work in the forestry sector in recent years, laying the groundwork for a wide range of rural sectors and professions, such as forest management, tourism, wood industries, and hunting (fao, 2020). but the manpower requirements of logging and forestry vary widely among the member states. kajanus et al. (2019) note that the pattern and peculiarities of individual forest, tree density, species affected from the harvesting activities, and the topography landscape all have a role in the possibility for effective utilization of forest modernization. poland (73,000), romania (48,000), sweden (41,000), and germany (40,000) had the highest employment rates (da silva & schweinle, 2022). there was a little drop (-0.2%) in forestry jobs in the eu between 2008 and 2018 (cook, 2020). eastern european countries like hungary (+50%, with over 7,000 more employees) and poland (+11%, with more than 11,000 new jobs, equal to +18% over the last decade) have seen increases in their employment rates in recent years. to the contrary, croatia saw the largest decline in forestry employment (-55%, or 17,000 jobs) over a ten-year period (fao, 2020). the principal goods of forestry, along with fuelwood, industrial roundwood is an essential material for the manufacturing of sawn wood and veneers. according to brack (2018), europe is a major player in the global roundwood market. the eu-27 countries rely heavily on the manufacturing of timber products (lovri’c et al., 2020). in 2018, the wood industry’s 397,000 businesses accounted for nearly a fifth of the overall manufacturing segment. these businesses directly or indirectly employed 3.1 million people (10.5% of the manufacturing sector’s workforce) and generated 138.6 billion euro in added value. according to data from 2018, 19.6% of all manufacturing establishments in the european union were involved in the manufacture of wood commodities (cook, 2020). when compared to the percentage of value added (7.1%), it is obvious that small and medium-sized firms (those employing between 51 and 249 people) are the backbone of the wood production industry (socoliuc et al., 2020). europe’s roundwood output has been on the rise over the past few decades, with a temporary dip in 2007–2008 due to the economic catastrophe. however, manufacture has shown encouraging signs of recovery since 2010, and has fully regained to pre–crisis stages (458 million m3) since 2013 (schier et al., 2022). recently, it was anticipated that output was 490 million m3 in 2018, an increase of 5.5 percent from 2017 and a considerable increase of 21.2 percent from 2000 (fao, 2020). hardwoods showed remarkable stability in output while conifers, which account for three-fifths of the entire roundwood output (60.4%, or 296 million m3), showed greater volatility (cook, 2020). the number of cubic meters of roundwood harvested in sweden in 2018 was 75.1% higher than in 2017, at 75.1 million. german roundwood production (71.8 million m3), finnish roundwood production (68.3 million m3), french roundwood production (48.2 million m3), and polish roundwood production (46.9 million m3) together account for nearly two thirds (63.3 %) of the eu’s roundwood production. in 2018, it was predicted that the european union’s total sawn wood production was 109 million m3, up from a decade earlier (+11.7%). sawn timber production in the eu remained led by germany (21.9%) and sweden (16.9%), as in previous years. only finland in the european union (eu) recorded a doubledigit percentage of global wood production (10.9%). germany (+4.6 million m3, or +23.7 percent), finland (+2.0 million m3, or +19.8 percent), and romania (+1.3 million m3, or +35.9 percent) were the primary contributors global sustainability research global scientific research 79 to the eu’s rising sawn wood production between 2008 and 2018. however, total eu roundwood production fell by 2% from 2019 to 2020, to 488 million m3, ending an eight-year period of continuous growth (eurostat, 2021). in spite of this, roundwood output is 21% higher than it was in 2000. figure 3 presents the percentage change in roundwood production in the eu between 2000 and 2020. since 2000, roundwood production has increased across the board, with the largest increases being in the netherlands (+185 percent), slovenia (+73 percent), germany (+57 percent), poland (+56 percent), croatia (+43 percent), and romania (+37 percent). some of those nations had quite humble beginnings. cyprus (-58 percent), france (-28 percent), and hungary (16 percent) saw the biggest percentage drops in their respective annual wood harvests (eurostat, 2021). figure 3. percentage change in roundwood production in the eu between 2000 and 2020 (eurostat, 2021) the usage of wood as a sustainable energy source has been on the rise. in 2020, about a quarter (23 percent) of eu roundwood production was used for fuelwood, while the remaining 77% was used for industrial purposes such as sawing, veneering, or pulping and papermaking. the percentage of total wood used for fuel therefore increased by six percentage points since the year 2000. fuelwood constituted the bulk of roundwood output in some member states in 2020; the netherlands (78 percent) and cyprus (74 percent). in contrast, over 90 percent of roundwood production in slovakia and sweden was reported to be industrial roundwood (eurostat, 2021). notwithstanding the above economic data’s testimony to the health of the wood-furniture supply chain, the european wood business has felt the effects of the decline in manufacturing employment, especially between 2000 and 2019 (9.6%) global sustainability research global scientific research 80 (marschinski & turegano, 2019). the integer of people engaged in the production of furniture and wood merchandise fell by nearly a quarter (26.3% and 24.9%, respectively) and men progressively made up the majority of these industries’ workforces (cook, 2020). more than 80% of workers in the forestry industry were men in 2019, but only 83.4% of those employed in the production of wood and its end product were men (cook, 2020). similarly, only 77.3% of those employed in the furniture manufacturing industry were men. european policy context and new developments in forestry as deforestation is expected to cause a widespread loss of forest canopy and wooden assets in numerous regions, the european commission is working to increase protections for forests by promoting global value channels not leading to deforestation or forest degradation. since 1980, the european union (eu) has established forestry sector guidelines and action programs that are sometimes applied in the common agricultural policy (cap), especially in rural development policies (sarvaová et al., 2019). during the 1990s, forestry went from being a tertiary component of the cap to an integral part of european sustainable development policy, leading to the adoption of the eu’s forest policy in 1998 (galiana et al., 2013; raihan, 2023i). it served as the very first benchmark guideline to include member state action instructions in line with sustainable forest management principles (rametsteiner & mayer, 2004; raihan, 2023j). the 2005 forest action plan (fap) served as the primary mechanism for putting the strategy into action, with the stated goal of “enhancing the forest heritage of the union, maintaining and strengthening the multifunctional role of forests through active and aware management of the forests” (aggestam & pülzl, 2020). to increase the availability of renewable and ecologically friendly raw materials, the function of forests was bolstered in climate change mitigation and adaptation guidelines with the introduction of the new european forest policy in 2013 and subsequent amendments (aggestam & giurca, 2021). figure 4 presents the policy areas pertinent to forest policy in the european union. figure 4. policy areas pertinent to forest policy in the european union. global sustainability research global scientific research 81 the forest policy has provided a uniform structure for community strategies and a fine-tuning of the forest strategies of each member country (falcone et al., 2020; aszalós et al. 2022). this is all in service to fostering sustainable forest management with an eye toward effective resource utilization. rehabilitation, resiliency, and proper preservation of all ecosystems, not only those characterized by forests, must be a primary priority to achieve a sustainable and climate-neutral economy by 2050 (fetting, 2020; raihan et al., 2022i). this new community strategy is strongly rooted in the green deal and the biodiversity policy for the 2030 agenda objective. these measures sought to improve the conservation and restoration of forest resources, increase sustainable management, and boost monitoring and the effectiveness of distributed organizing so that these ecosystems could perform a multifunctional part in mitigating ghg emissions and sequestering co2 equivalents (palah et al., 2020). this approach also includes efforts to promote the development of alternative resources and goods in addition to those of fossil sources and to encourage the growth of a forest economy that is not dependent on the harvesting of trees (ladu et al., 2020; viaggi et al., 2021). this is to further support a sustainable forest bio-economy for a future with zero climate impact. this included ecotourism based on the new strategy switching to the eu forest policy approved in 2013 and reviewed in 2018. the updated plan was released in july of 2021. finally, a plan for planting as a minimum 3 billion more trees in the eu by 2030 was included next to the strategy’s emphasis on sustainable reforestation (and afforestation) (lee et al., 2023). this tactic is tied to the cap by design and benefits from the cap’s operational interventions, which help make rural areas more thriving and prosperous (lier et al., 2022). the major financial support for the safeguarding and sustainable management of communal forests comes from these initiatives, which encourage versatile forestry and sustainable forest management and combine it with additional growth indicators (advice and offerings, education, expenditures, collaboration) that react to particular regional requirements (gordeeva et al., 2022). these measures also encourage forest growth through reforestation and the revival of agroforestry arrangements; they furnish operative and monetary instruments for fire and disaster preclusion; restoration following damage; investments in climate change adaptation and mitigation; and economic procedures for compensation and inducements for boosting the monetary worth of woodlands and pre-industrial timber (ascoli et al., 2023). in a highly dynamic environment such as the present one, the european commission has articulated the next generation eu as a solution to the catastrophe due to the epidemic, with the three struts being social interconnection, the green economy, and the digital transformation (fabbrini, 2022). from this vantage point, the carbon border adjustment mechanism seeks to shield eu-made goods from less environmentally friendly imports made by countries beyond the eu’s borders (mörsdorf, 2022). the “fit for 55” package mandates that the region become carbon neutral by 2050, with the interim objective being reached by 2030 (köhl et al., 2021; raihan, 2023k). because they are seen as vital (and steadily increasing) contributions in the shift and advancements of renewables, member nations will also be expected to meet a goal for the allocation of key basic equipment. the european union estimates that the furniture industry could benefit from the circular economy by creating an additional 160,000 jobs, reusing or recycling an additional 3.3 to 5.7 tons of materials, preventing the emission of an additional 3.3 to 5.7 metric tons of carbon dioxide equivalent, and increasing the value of the local economy by 4.9 billion euros. because of this, baumgartner (2019) argues that supply of wood and the furniture business have the problem of moving quickly enough to fully capitalize on the prospects presented by a truly sustainable development. however, the epa (environmental protection agency) confirmed in 2018 that biomass burning can be classified as an emission-free energy resource (raihan & tuspekova, 2022i; raihan et al., 2023g). this fundamental assertion endures to handle worldwide efforts on climate change despite the lack of scientific evidence. however, most academics agree that switching back to firewood as an energy source will significantly exacerbate the environment and pose a hazard to forests (schlesinger, 2018; raihan & tuspekova, 2022j). to compound matters for businesses producing high-quality wood goods like furniture manufacturers, this political stance will have a detrimental effect on the availability of wood supplies. discussion this research provides actual evidence for the intricate ecological-economic nexus that drives forestry and the forest industry as a whole. ecologically speaking, a deeper understanding of forest ecosystems is a vital piece of data needed to support a competitive supply chain strategy global sustainability research global scientific research 82 aimed at achieving the sustainable development goals (moreau et al., 2022). these goals were implemented by all nations as a feature of the united nations 2030 agenda and aim to protect the environment and reduce greenhouse gas emissions. miina et al. (2020) and rosa et al. (2023) note that current data on forest management techniques in europe is insufficient to provide an inclusive picture of ecological health, economic assessment, and biodiversity. in addition, it is possible that national statistics are incomplete since they exclude logging operations that serve essential (and likely informal) needs, such as house heating (picard et al., 2021). there is an immediate need for more precise statistics on forest management techniques and their influence on forest reserves, as well as more accurate measurement of forest land-use and associated change over (gschwantner et al., 2019; raihan, 2023l). better data on forest area and management changes will be available thanks to remote techniques (chirici et al., 2020; filizzola et al., 2022). high-resolution data on forests, including the density of tree cover, type of forest, and characteristics of small woody trees, will be made available through the european environment agency’s (eea) adoption of the global monitoring and environmental surveillance (gmes) system (chianucci et al., 2021). an exact monetary assessment of resource reserves, that is yet lacking at present (loomis et al., 2019; raihan, 2023m), requires all of this data. sawmills and other forest-use infrastructure are progressively disappearing across europe, despite the region’s relatively constant wood and other commodity production. the opposite is true; forest cover and volume, along with forests’ ability to sequester carbon, have grown steadily over the past few decades. while this is encouraging, it also comes with a caveat: the forests are increasingly at risk from both natural disasters (such as change of climatic conditions, floods, and landslides) and agrarian desertion, that can cause economic uncertainty and ecological deprivation, particularly in poor and remote areas (angra & sapountzaki, 2022; zhang et al., 2022). official statistics face a challenge when they are tasked with assessing the forest reserve, primarily in relations to good-quality wood intended for the furniture manufacturing chain. these statistics are meant to support a broad outline of economic and environmental trends to the aggregate user, with the goal of encouraging enhancements in records inclusiveness, statistic consistency, and timely update. by working together more closely, member nations and regional authorities can improve the quality of economic analyses and plan for the more efficient and environmentally friendly utilization of forest resources (edwards et al., 2022). due to the multifaceted nature of forest supply chain issues, it is challenging to keep tabs on them using only official statistics (garcia & hora, 2017; raihan, 2023n). while confirming the necessity for a larger interpretation of the many organizational components, such as the problem of assessing natural resources, in the economic analysis, this paper does the opposite. for instance, incomplete statistics, inconsistent methodological definitions, and sparse geographical detail continue to define this axis in the present day. to keep products, components, and materials as valuable as possible within the economy for as long as possible, area operatives appear to gain a heightened knowledge of the magnitude of investing at the firm level (mhatre et al., 2021). these measures, which call for a shift in corporate, territorial, and individual perspective and a fundamental rethinking of the way we produce and consume, are intended to steer the manufacture and consumption structures toward further effectual pathways by means of incessant and reformative sequences that reduce resource use, waste, and emissions in manufacture procedures (sahoo et al., 2019; raihan et al., 2022j). the adoption of circular techniques that ensure environmental sustainability over the medium term is increasingly common across all industries, with circular principles progressing most rapidly across furniture manufacturing firms, the supply chain’s most dynamic link (jarre et al., 2020; raihan & voumik, 2022b). most of the resources utilized in the manufacture of lumber appear to be destined for incineration or disposal. dead branch off, barks, residues, and debris are typically simply seen as something to be thrown away. despite being classified as waste, these materials may have a happy ending after all, leading to a valuable second use and a strong market position (pieratti et al., 2019; raihan, 2023o). most mulch on the market has traveled from far away to get to your garden. this adds a new dimension to the quest to reclaim the abandoned bark. barks and dead branches are often burned for cheap thermoelectricity, despite the fact that they can have significant nutrient value and serve an important role in soil protection. in addition to peat and other soil conditioners, residues can be used as a high-carbon fertilizer. the usage of "cascade" timber is encouraged in a circular forest management system. it entails giving material recovery a higher priority than wood combustion for energy production. the implementation of this idea benefits the regional timber supply chain and the global sustainability research global scientific research 83 economies of communities located in economically vulnerable locations near woods (jarre et al., 2020; raihan, 2023p). in this view, a tree trunk is a resource that should be put to good use across multiple industries, from construction and interior design to paper production and textiles. as mair and stern (2017) point out, "cascade" wood is a great way to practice thinking about forests as resources with multiple uses that benefit both the environment and human society. as such, effective info campaigns and territorial passageway constructions, unspoken as vital ideologies of data and distribution of information and performs, are necessary for interventions on the timberfurniture supply chain labor market, especially in light of the sustainability of environmental and the transition of energy more generally (marcinek & smol, 2020; raihan, 2023q). companies in the supply chain have been shown to have a heightened recognition of the significance of energy and climate challenges, as well as the insistence of strategic solutions to environmental concerns (adami & schiavon, 2021; lazaridou et al., 2021; raihan & tuspekova, 2022k). the potential for economically encouraging and promoting active enterprises from a viewpoint of not only positive environmental behavior, but also of technological advancement, ensures a fair transition on all fronts (economics, ecology, and information) toward novel manufacturing circumstances which are sustainable across a long period and resiliency to swift worldwide shifts in societies and environmental systems (marques et al., 2020). conclusion this paper looked at the many ways in which forestry contributes to society economically, including the formation of additional occupations, the revitalization of rural areas, and the improvement of people's physical and mental health through leisure activities. in addition to the direct economic benefits, forestry also benefits from the downstream input of wood, which is used extensively in the timber sector and continues to perform a large responsibility in the global energy mix. an increasing number of people are beginning to recognize the social and ecological advantages of ecotourism and additional practices of sustainable forest management. in this setting of opposites, the regulatory and institutional structure is highly variable and inconsistent in its ability to safeguard the sustainable management and protection of forests. it is strongly suggested that in the following years, new technical and product developments, as well as new legislative and programmatic tools, be implemented. declaration acknowledgment: not applicable. funding: this research received no funding. conflict of interest: the author declares no conflict of interest. authors contribution: asif raihan contributed to conceptualization, visualization, methodology, reviewing literature, extracting information, synthesize, and manuscript writing. data availability: the author confirms that the data supporting the findings of this study are available within the article. references adami, l., & schiavon, m.

indigenous communities perception; unique vulnerabilities; inclusion of indigenous perspectives introduction climate change has significant effects on human health and, the economy at the global level. however, pakistan, india, and afghanistan are more susceptible to climate change. global south countries are not equipped to mitigate the worst effects of climate change (ngcamu, 2023). pakistan is situated in a geographical location that is more vulnerable to climate-induced disasters. climate-induced disasters adversely affected the indigenous communities of the khyber pakhtunkhwa mountainous regions in pakistan. to counter the worst effect of climate change, the khyber pakhtunkhwa government also made a climate change policy in 2022. the main objective of this research is to examine the effectiveness of the khyber pakhtunkhwa climate change policy. however, the voices of indigenous communities are missing in the policy document of khyber pakhtunkhwa's climate change policy. the indigenous communities of khyber global sustainability research global scientific research 181 pakhtunkhwa province depend on forests, agriculture, and domesticated animals (khan, 2024). these natural resources are affected by climate change (ahmed, tan, shaikh waqas, kanasro, ali, & solangi, 2020). it is also argued that their resources were exploited by the colonial regime (khan and shah, 2021). pakistan in the post-colonial era also exploited the natural resources of indigenous communities. moreover, climate change further intersects with the already vulnerable position of indigenous communities living in districts chitral and merged districts of khyber pakhtunkhwa. forests, agriculture, biodiversity, and domesticated animals of the indigenous communities in khyber pakhtunkhwa are affected by climate-induced disasters. these natural disasters displaced the local population from their home town. each year, hundreds to thousands of homes are severely damaged, and large agricultural land is lost to floods. some villages such as reshun and brep, in chitral (a district of khyber pakhtunkhwa) are on the verge of disappearing entirely due to the frequency and scale of these natural disasters. northern pakhtunkhwa has several glaciers and freshwater sources for agriculture (javed, 2023). however, as temperatures rise, these glaciers continue to melt, quickening the loss of glacier bulk and posing a probable danger to future water accessibility. additionally, the increase in extreme climate events, such as floods and droughts, intensifies the vulnerability of rural populations in the northern districts of khyber pakhtunkhwa. therefore, the indigenous communities of this region are more exposed to climate-induced disasters. moreover, pashtun indigenous populations living in the merged districts are also vulnerable to climate change. historically, they faced the worst colonial policies and pakistan also exploited their natural resources (khan, 2024a). recently in the war on terror, they were displaced from their home town (khan, 2024b). climate change further intersects their vulnerability. therefore, khyber pakhtunkhwa is the first province of pakistan to develop a climate change policy aligned with the national climate change policy, of 2021. however, in this climate change policy, the indigenous voices are missing. this research focuses to what extend khyber pakhtunkhwa government, a province of pakistan, considering the native indigenous community's perspectives in formulating climate change policy? it also assess the perception of indigenous communities about the climate change policy of the khyber pakhtunkhwa government, a province of pakistan. major indigenous communities in khyber pakhtunkhwa kho indigenous community lives in district chitral. 'khowar' is the spoken language of the kho indigenous community (abdul aziz, ullah, & pieroni, 2020; sabbah, abbasi, aziz, benhasher, pieroni, a., aldosari & amin, 2024). kalash community is the smallest minority group living in the district of chitral, pakistan. the estimated population of this community is 4000 (khan, khan and kamal, 2024). plenty of research has been done. however, there is no authentic evidence, to ascertain their origins. a global human rights defense paper titled, 'tribe of kalash: the last kafir' describes them as the last of the people of 'kafiristan' – an area that once encompassed the entirety of northwest pakistan and eastern afghanistan before being divided by the durand line – who retain elements of their ancestral cultural identity. pashtuns live in afghanistan and also inside pakistan. they also live in the province of khyber pakhtunkhwa and recently merged districts of khyber pakhtunkhwa. they have limited low land and live in mountainous terrain. pashtun land is full of natural resources. however, their resources in colonial and post-colonial periods were exploited by the british and pakistan (khan, 2024). global sustainability research global scientific research 182 literature review the role of indigenous and local people is highly acknowledged in climate change, particularly in mitigation and adaptation (chanza, musakwa and kelso 2024). traditional ecological knowledge can guide and sustain climate adaptation efforts in climate change policies (datta and kairy, 2024). traditional ecological knowledge in the climate change policy can easily protect marginalized indigenous communities (redvers, aubrey, celidwen & hill, 2023). the well-being and response to climate change of indigenous communities are embedded in prevailing socio-cultural capital (rittelmeyer, caretta, dowler, vora, seigerman, reddy & mukherji, 2024). many countries especially australia and new zealand engaged indigenous communities in climate change initiatives (suhaeb, tamrin, jumadi and irwan, 2024). these countries design climate change policies to address the unique vulnerabilities of indigenous communities. in pakistan, khyber pakhtunkhwa was the first province to make a climate change policy. this policy emphasises the need for adaptation and mitigation actions to address the worst effects of climate change. the prime objective of the khyber pakhtunkhwa climate change policy is to control the worst effects of climate change on the natural economic resources and people of this province. this policy was created in collaboration with various government departments, including forestry, wildlife, irrigation, agriculture, livestock, and food, as well as academic institutions, ngos, civil society organizations, and other relevant stakeholders. the policy comprises 22 objectives which revolve around the adaptation and mitigation approach. however, the voices of vulnerable and indigenous communities are important in climate-related strategies (ahmed, tan, shaikh, waqas, kanasro, ali, and solangi, 2020). for an effective climate change policy, it is essential to protect the natural livelihood resources of the indigenous communities (nwankwo, 2025). indigenous communities are dependent on natural resources (mishra, sudarsan, santos, mishra, kar, baral, & pattnaik, 2021). in pakistan, indigenous communities live in an agro-based region. they have to rely on agriculture to sustain their living. wheat, maize, potatoes and many other agricultural products are grown in the geographical location of these indigenous communities. apples, pears and walnuts are also exported to different cities in pakistan. the drastic climate changes have crippled the livelihood resources. the agricultural goods require a suitable climate to grow. however, changes in the rain cycle affected their agricultural products. climate change-induced disasters such as glof and flash floods wash away agricultural land in khyber pakhtunkhwa (khan, 2024). however, the climate change policy of khyber pakhtunkhwa cannot address the unique vulnerabilities of the indigenous communities (shah, khan, gong, ahmad, naqvi, ullah & karmaoui, 2023). the kalasha community also relies on natural resources and agriculture for livelihood. they are reliant on forests for various purposes such as wood for fuels and construction. moreover, fruits and dry fruits are abundantly grown here and exported to local markets. the last few years climate changes have crippled livelihood resources as continuous flooding and glof have demolished large forest areas and agricultural lands (ajani and van der geest, 2021). moreover, pashtun indigenous communities living in merged districts rely on natural resources. agriculture and domesticated land is the source of livelihood. the pashtun indigenous community has been badly affected by the war against terror. security is the major challenge in this region (khan, israr, and khan, 2019). climate change further intersects their marginalities. climate change causes a scarcity of resources. it fuels conflict over water and land in the pashtun region, especially in the tribal belt. therefore, without an understating of the problems of indigenous communities, the climate change policy will not be effective. hence, this research study examines the perception of indigenous communities about climate change policy and their unique vulnerabilities to climate change. global sustainability research global scientific research 183 theoretical framework this research essay focuses on the climate change policies of the khyber pakhtunkhwa government and the missing voices of indigenous communities in the khyber pakhtunkhwa climate change policy. the customary terrestrial management approach provides theoretical insight to this study (guerrero-gatica, mujica, barceló, vio-garay, gelcich, & armesto, 2020). indigenous people contribute to environmental governance. it is important to understand their concerns and perspectives while formulating climate change policies. the voices of indigenous people in climate change policies must be included. moreover, the two-eyed seeing approach utilises western and indigenous knowledge to develop a climate change policy (macfarlane, charles-norris, warren, mahendra, butler, hayes and armstrong, 2022). this approach gives insight into understanding and utilising both indigenous and western knowledge. two-eyed seeing requires groups to weave between each respective way of knowing, as indigenous knowledge may be more applicable than western in certain situations and vice versa. it allows a diverse group of people to use all understandings to improve the world. methods and materials a qualitative approach is applied to gain firm insight into the climate change policies of the khyber pakhtunkhwa government a province of pakistan. various stakeholders like elderly community members of indigenous communities’ policymakers, and civil society are being interviewed in detail which provides a firm understanding regarding the effectiveness of climate change. in-depth interviews enable us to understand the perception of khyber pakhtunkhwa indigenous communities. the purposive sampling technique was used to select respondents from indigenous communities such as khu, pashtun and kalasha. climate change affected their natural resources. they have no access to climate finance. the government has failed to protect their livelihood resources. the data was collected in six months. the primary data was collected from both males and females and from local civil society organizations to understand their perception of climate change. the primary data is thematically analyzed to understand the indigenous communities' perspective on their unique vulnerabilities to climate change and khyber pakhtunkhwa's climate change policy. data analysis and discussion analyzing khyber pakhtunkhwa's climate change policy through indigenous perspectives perceptions of policy effectiveness globally, indigenous communities are more marginalized due to climate change. states and civil society organizations assert indigenous perspectives in forming climate change policy. the impacts of climate change have become increasingly evident in the geographical location of indigenous communities living in the northern pakhtunkhwa province of pakistan over the past several years (ahmad, asad and irtaza, 2023). indigenous people have suffered from natural disasters such as floods and glacial lake outburst floods (glofs) (hussain and khan, 2024). however, the indigenous community perceived that without the inclusion of indigenous voices climate change policy will not effectively protect the natural resources of indigenous communities. in this regard, one of the community members stated that “in recent years, visible changes in the weather have highlighted the pressing nature of climate change. traditionally predictable patterns have been replaced by unpredictable fluctuations, making it challenging for our communities to adapt. last year, for instance, global sustainability research global scientific research 184 there was an exceptional absence of snowfall in january, a phenomenon that was followed by an unexpected cold spell and heavy rains in april. these unexpected changes in weather badly affected our local communities” (individual interview may 7, 2024). the government has failed to address the effects of climate change on the indigenous communities. these indigenous communities have unique relationships with their land and resources. they need a different climate change policy. climate change has distinct effects on the indigenous communities living in mountainous regions. the people especially the indigenous communities of khyber pakhtunkhwa are dependent on the local natural resources (khan and shah, 2021). they have different types of challenges as compared to other communities. it is essential to design a climate change policy for the indigenous people and their indigenous knowledge and resilience should be strengthened for an effective climate change policy. for example, australia and new zealand governments design for their indigenous communities. in this regard, one community member stated that ; “the current khyber pakhtunkhwa climate change policy does address the climate changerelated challenges of indigenous communities. the government does not provide any help to these indigenous communities. our indigenous people mainly utilized their socio-cultural capital to respond to climate-induced disasters. we have a unique experience of climate change as compared to mainstream society. the current climate change policy does not preserve our cultural heritage (individual interview, 05 july 2024)” growing temperature affects the domesticated animals and grazing land (khan, 2024). pakistan is warming faster than the global average due to geographical location data from the pakistan meteorological department shows that temperatures have been gradually rising over recent decades, with average winter temperatures increasing by approximately 0.06 degrees celsius per decade. high temperatures also affected the local domesticated animals. however, the climate change policy of the khyber pakhtunkhwa government does not have a clear climate action plan to protect the livelihood resources of the indigenous population. one of the respondents stated that; high temperatures and variations in the rain cycle badly affected the grazing land. many pastoral communities have changed their profession because their animals do not survive due to climate change. the climate change policy does not address the unique vulnerabilities of the pastoral communities (individual interview, 25 jun 2024). the indigenous communities of khyber pakhtunkhwa are more susceptible to climate change due to droughts, and land sliding. the indigenous communities have specific land rights and governance systems. it needs to be recognized in the climate change policy in khyber pakhtunkhwa. the current climate change policy does not address the issues of instant warming, melting of glaciers, and an increase in natural disasters like floods and glacial lake outburst floods (glofs). the climate change further intersects their socio-economic disparities (łukaniszyn-domaszewska, mazur-włodarczyk & łukaniszyn, 2025). natural water resources are severely threatened by climate-related concerns (ahmed, zounemat-kermani & scholz, (2020). one of the respondents stated that “we are facing severe problems due to climate change. our people face distinct challenges related to climate change” (individual 13 august 2024). global sustainability research global scientific research 185 climate change policy needs a framework to recognize indigenous knowledge and socio-cultural capital for effective climate change policy. resilience and adaptation strategies the kp policy has not taken the local indigenous communities' perspectives about mitigation and adaptation strategies. it is considered the major weakness of kp's climate change policy. to address causes of susceptibility experienced by indigenous folks, research shows that operative climate adaptation in mountainous areas demands addressing socioeconomic variables and assimilating customary understanding (gråd, lindhjem, jacobsen, eriksson, åström, karttinen, and fromberg, 2024). indigenous communities have deep spiritual and cultural ties with their land and environment. however, the current climate change policy is blind to the indigenous knowledge and resilience to climate change. it also does not address the local sociocultural capital to counter the worst effects of climate change. one of the respondents stated that ; “we, the indigenous people are closely attached to our traditions and land. our ancestors have inherited many beautiful traditions and useful ways to such mountainous regions. so it is important to consider our local understanding while formulating environmental policies” (individual interview, 07 july 2024)” disregarding customs could result in the community's resistance and unsuccessful policy execution (khan, cheng, shah & ullah, 2020). indigenous communities have unique indigenous strategies for adaptation that align with their culture. to support sustainable environmental management, policies should be crafted to use indigenous ingrained ecological knowledge. the effective accomplishment of environmental policy especially in indigenous communities is hindered by several problems. limiting the use of forest resources is a key problem that has an instant influence on the indigenous community's standard of living. these restrictions cause shortages of vital assets like firewood and lumber, which makes gathering them more labour-intensive. they do not have any alternative sources of income, and the local individuals, therefore, face a financial crisis. the carbon crediting policy should be introduced. it will provide an alternative source of income to indigenous communities. it will create revenue for the people protecting the forests in this region. in this regard, one of the community members stated that ; “the forest is our source of livelihood. we rely on the forest and we use it as firewood. however, the current climate change policy of the khyber pakhtunkhwa government does not offer any alternative resources to indigenous communities that rely on the forest (individual interview 17 september 2024). the indigenous community has separate and distinct climate-related problems. they need a dedicated climate-related fund to provide alternative livelihood resources. the existing climate-related funds are not enough to address the unique vulnerabilities of indigenous communities. global sustainability research global scientific research 186 bridging the communication gap between legislators and local communities apart from the policy-development phase, neglecting the indigenous wisdom (due to communication gaps or lack of consultation) creates opposition and the local people deliberately do not protect the forests which discourages community forestry. thus, such complications further led to misunderstandings about the goals and advantages of policies making it more challenging to implement the strategies. however, through community involvement, we can improve the effectiveness of climate change policies to counter the worst effects of climate change (ullah, bavorova, shah and kandel, 2024). ensuring the inclusion of indigenous knowledge and socio-cultural capital can increase the chance of acceptability of policies. further, the community should be given a fair and unbiased chance to share their concerns while formulating policies. in this regard, one of the community members stated that ; the government takes into confidence the local people and also offers alternative livelihood resources to decrease their dependency on natural resources. the government should initiate the development project and ensure their access to climate financing for the effective climate change policy (individual interview, 25 august 2025). however, advanced countries like canada, new zealand and the united states of america made separate climate change policies for indigenous communities with consultation. however, indigenous issues are not addressed in the climate change policy. the local community should be involved in climate action plans. unique vulnerabilities of indigenous communities moreover, reducing socioeconomic inequalities and increasing public support for ecological measures can be attained by assuring that the advantages of ecotourism and other business activities are distributed fairly. indigenous communities have unique vulnerabilities. they are dependent on natural resources. these natural resources are badly affected by climate change-induced disasters. therefore, they need special treatment to address their socio-economic issues. for this purpose a policy need to be revisited. legislators can improve more inclusive, viable, and successful environmental policies that increase the well-being of indigenous populations while simultaneously preserving the environment by tackling these prospects and problems. conclusion this research reveals that climate change has a significant effect on the indigenous population at the global level. they have unique vulnerabilities. they rely on natural resources. conservation of natural resources should be a priority of the climate change policy. different countries at the global level recognized the indigenous perspectives on the climate change policy. the government should work to ensure the indigenous community's inclusion in the climate action plan. the new zeland and australian government incorporate traditional knowledge and ensure equitable participation in climate action. in this study, the theoretical framework two-eyed seeing approach mentioned above emphasizes indigenous and western knowledge for the effective climate change policy. the khyber pakhtunkhwa climate change policy is not based on scientific research. neither takes into account indigenous knowledge and resilience. it is included that there is a considerable communication gap between the legislators and the local community. the unequal distribution global sustainability research global scientific research 187 of advantages gained from ecotourism has worsened the socioeconomic disparities that highlight the need for fairer and unbiased policies. it is essential to improve the efficiency of policy through the integration of indigenous knowledge and customs. it is also important to highlight the indigenous women's problems due to climate change. it is a grey area for research to investigate climate change's effects on indigenous women. policy recommendations community-based approaches • indigenous knowledge is culturally embedded. this approach can strengthen climate policies by ensuring they are inclusive, equitable, and culturally appropriate. we need to support indigenous rights, and commitment to bridge the gap between traditional knowledge and modern science. • engaging indigenous communities in climate-related problems to address their unique vulnerabilities. • restructuring the climate change policy to address the unique vulnerabilities of the indigenous communities. ethical considerations this research is conducted responsibly while keeping in view research ethics. the participants’ rights are properly protected and the finding of this research is not harmful for anyone. this research contributes to the positive impact on society and communities especially for indigenous people in the different parts of the world. declaration

veterinary and animal sciences, university of rajshahi, rajshahi 6205, bangladesh 2national university of malaysia, bangi 43600, selangor, malaysia corresponding author: asif raihan. email: asifraihan666@gmail.com received: 16 july, 2024, accepted: 25 august, 2024, published: 27 august, 2024 abstract as the global population continues to expand, it is imperative for livestock farming to undergo necessary adaptations in order to effectively address the escalating food demands and enhance productivity. concurrently, it is imperative to acknowledge and tackle concerns pertaining to animal welfare, environmental sustainability, and public health. the primary aim of the article is to provide a comprehensive examination of the latest advancements in the utilization of biometric devices, big data, and blockchain technology for the purpose of digitizing animal husbandry within the context of precision livestock farming (plf). biometric sensors are physiological devices utilized for the purpose of monitoring the health and behavioral patterns of an individual animal. this information can be utilized by farmers to do population-level analysis. big data analytics solutions employ statistical algorithms to examine extensive and intricate data sets, detecting significant trending patterns and offering advisory recommendations for farmers' decision-making. these systems are designed to interpret and integrate data obtained from biometric sensors. blockchain technology, when combined with sensors, facilitates the secure and convenient tracking of animal products throughout their journey from the farm to the table. this approach demonstrates efficacy in the surveillance of disease outbreaks, the prevention of economic losses, and the mitigation of foodrelated health pandemics. the implementation of plf technology within the livestock industry has the potential to contribute to the attainment of sustainable development. keywords: animal husbandry; precision livestock farming; technology; digitalization; sustainability introduction according to projections, the global human population is anticipated to surpass 9 billion by the year 2050, indicating a growth of almost 2 billion individuals in comparison to the present population. the primary locus of population growth will be observed in developing nations. according to raihan and himu (2023), the increase in population and rapid growth in these countries will result in a significant amplification of the market demand for animal agricultural goods. in developing nations, the production of livestock presents dependable food sources, employment opportunities, and potential for increased cash. a substantial proportion of the market demand for animal products will be met by local production. furthermore, in light of the growing population and the escalating global sustainability research global scientific research 2 need for animal protein, consumers are exhibiting heightened concerns regarding the detrimental impacts of livestock production on the environment, public health, and animal welfare (ochs et al., 2018). given the diminishing availability of water and land resources, livestock farmers must devise strategies to enhance output while utilizing their few resources in a sustainable fashion (baldi & gottardo, 2017). moreover, a notable transformation in societal perspectives, namely among consumers, has further emphasized the imperative for conscientious research and innovation in order to effectively tackle pressing concerns in cattle production through the use of circular and sustainable methodologies (himu & raihan, 2023). the process of digitalization is expected to facilitate the progressive achievement of these objectives. the application of digital technologies in livestock farming will provide a thorough examination and accurate understanding of the dynamics and impacts of climate change on the ecology of farm animals (raihan, 2023a). the successful control and mitigation of novel infectious animal illnesses in transboundary livestock, including those that can be transmitted to people (zoonosis), necessitates the adoption of strategic approaches and optimal methodologies. the process of digitalization has the potential to offer several solutions, including the development of prediction tools targeted at the prevention, mitigation, and preparedness of animal diseases and pandemic situations (raihan, 2023b). to effectively meet the growing demand for animal protein and simultaneously tackle concerns related to environmental sustainability, public health, and animal welfare, farmers and animal scientists are increasingly relying on precision livestock farming (plf) technologies to digitize the entire process of livestock agriculture. the present research investigation examines the application of plf technologies, encompassing biometric sensors, big data, and blockchain technology, with the aim of augmenting livestock productivity, particularly with regards to improving animal health and well-being. figure 1 illustrates the application of plf technology in the context of cattle production. figure 1. livestock production with plf technologies (neethirajan & kemp, 2021). global sustainability research global scientific research 3 livestock farming trends in recent years, significant advancements have been achieved in diverse domains, including automated feeding systems, milking robots, waste management, and the enhancement of production efficiency through the utilization of precision instruments, animal breeding techniques, genetic research, and nutritional interventions. notwithstanding the aforementioned advancements, significant challenges persist. the implementation of intensive livestock management practices is crucial in order to meet the increasing demand for animal products. nevertheless, the density and overcrowding of livestock housing provide difficulties for farmers in effectively monitoring the animals' health and welfare (helwatkar et al., 2014). the escalating impacts of climate change are anticipated to heighten the susceptibility of livestock animals to illnesses, heat stress, and various health hazards (bernabucci, 2019; raihan, 2023c). as a result, there will be a heightened demand for expeditious identification of health issues and illness outbreaks, comprehension of disease transmission mechanisms, and implementation of preventive measures to alleviate substantial economic repercussions (thornton, 2010; raihan, 2023d). in light of growing apprehensions regarding animal welfare, transparency, and environmental sustainability (raihan, 2023e), there has been a surge in the exploration of digitalizing livestock agriculture through the utilization of plf technology (klerkx et al., 2019). the plf technologies utilize process engineering methodologies to operationalize the automation of livestock agriculture. this technology enables farmers to effectively monitor the welfare and health of extensive animal populations, promptly detect issues with individual animals, and potentially anticipate potential problems through the analysis of historical data (benjamin & yik, 2019). recent advancements in plf technologies encompass a diverse range of applications. examples of common applications include the surveillance of bovine behavior, the identification of vocalizations such as screams in pigs, the monitoring of coughs in several animal species to diagnose respiratory ailments, and the detection of bovine pregnancy through alterations in body temperature. the utilization of plf technology has the potential to assist farmers in the surveillance of infectious illnesses within the realm of livestock agriculture, hence enhancing both food safety and availability. the implementation of plf technology would ultimately enhance animal welfare and mitigate food safety issues, while simultaneously optimizing resource consumption (norton et al., 2019). livestock industry challenges this study identifies three key factors that provide significant challenges in the efficient monitoring of animal welfare: cost, reliability, and timeliness of observations. a considerable proportion of current techniques are characterized by their time-consuming nature, demanding substantial work and thus, incurring high costs (jorquera-chavez et al., 2019). animal husbandry practitioners often rely on the observations made by stockpeople to detect and address health and welfare concerns. nevertheless, a considerable disparity exists among commercial establishments in terms of the size of their workforce in relation to the number of animals they house. for example, on a commercial pig farm, the typically observed ratio of stockpersons to pigs is 1:300 (benjamin & yik, 2019). even stockpeople who possess exceptional attentiveness and advanced skills may inadvertently overlook animals in a dangerous condition. third-party auditing programs offer comprehensive evaluations of animal welfare; yet, they often incur significant costs and consume substantial amounts of time. the implementation of plf technologies, specifically biometric sensors, would facilitate the real-time monitoring of animal welfare by farmers, in a manner that is characterized by precision, impartiality, and consistency. this will enable the prompt identification of issues and the timely execution of proactive measures to mitigate significant operational shortcomings. polymerase chain reaction (plf) technologies offer a non-invasive sampling method, facilitating the collection of precise data by farmers and researchers. these measurements can then be global sustainability research global scientific research 4 employed to address welfare concerns (jorquera-chavez et al., 2019). precision farming (plf) technologies provide the capacity to mitigate resource consumption. the implementation of a proactive and tailored strategy towards animal health has the potential to substantially decrease the dependence on pharmaceutical interventions, particularly antibiotics. the escalating apprehension among consumers regarding the sustainability and welfare of animal products has resulted in a heightened need for transparency from livestock farmers (raihan, 2024). the implementation of blockchain technology facilitates the establishment of transparency between farmers and consumers on food offerings, hence alleviating the need for farmers to allocate additional time resources. in the present setting, the time that is conserved could be more efficiently allocated towards the supervision of issues pertaining to animal welfare, public safety, and environmental sustainability (benjamin & yik, 2019). biometric sensors biometric sensors are utilized to observe and analyze the behavioral and physiological attributes of livestock, hence facilitating comprehensive evaluation of an animal's health and overall welfare by farmers over a specified duration. at present, there exists a wide array of biometric sensors that can be classified into two main categories: non-invasive and invasive designs. one example of versatile non-invasive sensors utilized in barn monitoring encompasses surveillance cameras and sensors integrated into feeding systems, which enable the monitoring of animal weight and feed intake. non-invasive sensors encompass a range of devices that can be conveniently affixed to animals, such as pedometers, gps (global positioning system), and mems (micro-electromechanical) based activity sensors. these sensors are employed for the purpose of monitoring and mapping animal behavior (helwatkar et al., 2014). in livestock, invasive sensors are commonly utilized through ingestion or implantation, although their exploration in this context is very infrequent. the utilization of these sensors becomes advantageous in the surveillance of internal physiological parameters in dairy cows, including rumen health, body temperature, and vaginal pressure (helwatkar et al., 2014). in order to enhance operational efficiency and reduce resource requirements, the livestock industry has adopted biometric sensor technologies to effectively monitor a greater population of animals. the utilization of this approach enables the industry to obtain precise and impartial assessments of animal health and welfare (helwatkar et al., 2014). the data collected by the sensors is subsequently stored in databases and subjected to analysis using algorithms, which are computational procedures designed to address specific problems in a sequential manner. real-time livestock biometric sensors employ sophisticated algorithms to interpret unprocessed sensor data and produce biologically meaningful insights. this encompasses quantitative measures such as the average duration of different actions displayed by animals within a particular day, as well as fluctuations in activity levels across specific time intervals (benjamin & yik, 2019). furthermore, these sensors have the capability to monitor behaviors based on predetermined criteria and alert farmers when an animal's behavior deviates from typical patterns. this allows farmers to examine the animal and implement suitable measures to improve its overall health and welfare. the integration of biometric sensors with big data analytics, artificial intelligence, and bioinformatics technologies, including computational genomics, holds promise in identifying animals possessing desired traits and facilitating their inclusion in breeding initiatives (ellen et al., 2019). the forecasted trajectory indicates a rise in the utilization of biometric sensors within the livestock farming and animal health sectors over the course of the forthcoming decade. the aforementioned benefits stem from their capability to deliver instantaneous outcomes, exceptional precision, and the aptitude to amass substantial volumes of data. the timely acquisition of information regarding the welfare of animals facilitates prompt intervention and frequently mitigates the necessity for supplementary interventions. thermal infrared (tir) imaging presents a global sustainability research global scientific research 5 viable alternative to invasive thermometers, which necessitate the confinement and regulation of animals, for the purpose of monitoring their body temperatures. the application of thermal infrared imaging (tir) in the eye area and general skin temperature has demonstrated potential in the early detection of stress levels and diseases, surpassing the capabilities of earlier methodologies, with a typical detection timeframe of 4-6 days (koltes et al., 2018). the implementation of this approach facilitates prompt intervention and mitigates the potential transmission of diseases among animal populations, such as flocks or herds (martinez et al., 2020). in the realm of livestock animal monitoring, the primary non-invasive sensors utilized encompass thermometers, accelerometers, radiofrequency identification (rfid) tags, microphones, and cameras. this technological equipment facilitates the ability of farmers to watch and monitor many parameters within the barn, including temperature, activity levels, sound levels (such as vocalizations, sneezing, and coughing), and specific behaviors (such as aggression in pigs) (benjamin & yik, 2019). the utilization of thermometers, in conjunction with physiological sensors such as thermoinfrared (tir) and heart rate monitors, enables the assessment of stress levels in animals prior to their slaughter. the aforementioned measurements might thereafter be juxtaposed with meat quality indicators in order to enhance the consistency and superiority of consumer products (jorquera-chavez et al., 2019). through the utilization of biometric sensors, researchers are able to promptly detect variations in heart rate pertaining to both positive (eustress) and negative stressors. additionally, it is possible to do comparisons of individual reactions among animals and see the temporal variations in heart rate resulting from different stressors. in a study using porcine subjects, the introduction of a negative stressor led to a transient elevation in heart rate lasting for a duration of one minute subsequent to the exposure to a high decibel auditory stimulus. the administration of a positive stressor, such as the provision of a towel for play, led to a sustained elevation in heart rate for a duration of two minutes. conventional or indirect measures of welfare may exhibit limitations in their capacity to detect intricate fluctuations (joosen et al., 2019). heart rate monitors are considered to be highly valuable instruments for assessing physiological well-being and the production of metabolic energy. nie et al. (2020) have demonstrated that biometric sensors, specifically photoplethysmographic sensors, can be conveniently affixed to ear tags or other anatomical regions, enabling uninterrupted monitoring of cardiopulmonary activity in livestock. there is a growing trend among livestock producers to employ rfid sensors, which can be affixed to ear tags and collars or positioned subcutaneously, for the purpose of monitoring a wide array of behaviors such as general activity, eating patterns, and drinking habits. the application of microphones in acoustic analysis facilitates the monitoring of vocalizations and coughing, hence enabling the timely identification of welfare issues among farmers. microscopic devices offer the advantage of being easily and inconspicuously deployed within barns for the purpose of monitoring large animal populations (mahdavian et al., 2020). likewise, the strategic placement of cameras within barns enables the recording of a wide array of practical data. according to jorquera-chavez et al. (2019), computational algorithms designed for video analysis have the capability to detect alterations in the posture of animals, potentially serving as an indicator of lameness and other health conditions. the utilization of camera image analysis facilitates the surveillance of several parameters relevant to animal behavior, including weight, mobility, water consumption, individual identification, and aggression (norton et al., 2019). the advancement of facial detection technology is becoming a larger priority in the field of automated animal welfare monitoring. the application of machine learning algorithms in facial recognition technologies facilitates the detection of distinct facial traits in animals, hence enabling the recognition of individuals or the monitoring of emotional state fluctuations (marsot et al., 2020). a cohort of researchers specializing in animal welfare is currently engaged in the advancement of "grimace scales" for various animal species. the primary objective of these scales is to facilitate the reliable monitoring of animals' emotional states, with a specific emphasis on pain (viscardi et al., 2017). research has indicated that livestock animals frequently experience stressful procedures, including global sustainability research global scientific research 6 dehorning, tail docking, and castration (viscardi et al., 2017; müller et al., 2019). accurate identification of behavioral intent in animals can be achieved through the examination of facial expressions. according to camerlink et al. (2018), pigs exhibiting aggression exhibit distinct facial changes in contrast to those that reduce or refrain from engaging in violent behavior. previous research has proposed facial detection as a potentially costeffective alternative to rfid tags for the purpose of identifying individual animals (marsot et al., 2020). the utilization of biometric sensors is of paramount importance in the mitigation of disease impacts and transmission. these sensors have the ability to monitor variations in temperature, patterns of behavior, levels of sound, and physiological indications including ph levels, metabolic activity, pathogens, and the identification of toxins or antibiotics within the human body. presently, the excessive usage of antibiotics in the context of cattle farming represents a noteworthy concern that carries substantial implications for human health (himu & raihan, 2023). the capacity to identify the existence of antibiotics empowers farmers to administer healing measures to animals afflicted with ailments, while concurrently guaranteeing the generation of secure and nourishing animal commodities for the global populace. biologic sensing technologies have the potential to be utilized for the detection and identification of pathogenic infections, such as avian influenza, coronavirus, and johne's disease. johne's disease is a pathogenic bacterial infection that exerts detrimental effects on ruminant animals, resulting in substantial economic ramifications for agricultural practitioners. biometric sensors possess the ability to identify biological markers linked to inflammation, hence facilitating the surveillance of diseases on a significant magnitude. one potential use of thermal infrared imaging (tir) involves the identification of foot disorders through the analysis of foot pictures (jorquera-chavez et al., 2019). figure 2 illustrates the various applications of biosensors within the context of animal production. figure 2. livestock biosensors applications. global sustainability research global scientific research 7 big data and machine learning the application of biometric sensors and bioacoustic devices in the surveillance of livestock welfare and health yields substantial volumes of data that necessitate processing and analysis to give valuable insights for animal management. considerable advancements have been made in the domain of big data analytics, a discipline that encompasses the acquisition and analysis of vast and complex datasets (wolfert et al., 2017; raihan, 2023f). the concept of big data pertains to datasets characterized by an extensive quantity of rows and columns, hence posing challenges in terms of visual data analysis. moreover, the aforementioned data sets sometimes encompass a multitude of variables or predictors, rendering them intricate and unsuitable for conventional statistical methodologies (morota et al., 2018). the "4 vs" model, as proposed by wolfert et al. (2017) and koltes et al. (2019), encompasses four fundamental attributes that define big data. these attributes include volume, which refers to the numerical quantity of data; velocity, which pertains to the speed at which data is accessed or utilized; variety, which encompasses the diverse forms of data; and veracity, which involves the processes of data cleaning and editing. the utilization of modern data analytics and modeling in plf technologies enables managers to obtain precise information pertaining to food requirements, reproductive circumstances, and declining productivity trends. this information also serves to identify potential difficulties associated with animal health and welfare. the analysis of data obtained from sensors by big data models enables the identification of irregularities that have the potential to affect animals. the utilization of big data models enhances the efficacy of sensor technology by facilitating the generation of valuable insights for agricultural purposes. these insights encompass the ability to predict the probability of future events, enhance farmer responsiveness and decision-making processes, and potentially enable the categorization of animals according to their specific requirements. consequently, this facilitates the optimal allocation of resources (koltes et al., 2019). the data obtained from sensors can be classified into two distinct categories: animal-oriented data, which pertains to the phenotypic features of the animals, and environment-oriented data, which pertains to the characteristics of the surrounding environment. simultaneous monitoring of both data types is crucial due to their substantial impact on animal health and productivity. the incorporation of animal and environmental data in the adoption of digital technologies in cattle agriculture holds promise for improving multiple facets, including health management, nutrition, genetics, reproduction, welfare, biosecurity, and greenhouse gas emissions (piñeiro et al., 2019). the analysis of data can be classified into two primary categories: exploratory and predictive data analysis. exploratory methodologies involve the examination of historical data in order to find pertinent elements, while predictive models employ data to make projections about future events based on predetermined criteria (sasaki, 2019). when dealing with extensive data sets, it is imperative to employ precise data analysis techniques. according to koltes et al. (2019), the inclusion of varied data necessitates the examination of multiple elements within the given situations. additionally, it is important to eliminate extraneous information in order to cleanse the data systematically. the utilization of predictive approaches by farmers enables them to anticipate future outcomes and implement a proactive management strategy (wolfert et al., 2017). the application of big data technology has the potential to enhance disease transmission monitoring through the establishment of contact networks and the identification of people with a heightened risk (vanderwaal et al., 2017). machine learning (ml) is a subfield within the realm of artificial intelligence that employs algorithms to generate statistical predictions and establish conclusions (morota et al., 2018; raihan, 2023g). data mining is a systematic procedure that entails the training of databases to identify patterns and extract relevant information (raihan, 2023h). machine learning (ml) is an emerging domain within the study of plf that leverages extensive datasets to shape computer algorithms. these algorithms have the capability to continuously gather information from sensor data and enhance their performance autonomously, without the need for human data analysis (benjamin & yik, 2019). global sustainability research global scientific research 8 machine learning (ml) techniques are extensively employed in the field of animal genetics research for the purpose of predicting phenotypes based on genotypic data, identifying abnormalities within a population, and performing genotype imputation. the utilization of machine learning (ml) extends to the detection of mastitis in dairy farms through the implementation of automated milking technology, the estimation of body weight using picture analysis, and the monitoring of microbiome health (morota et al., 2018). machine learning (ml) and big data analytics have the potential to improve the well-being and efficiency of dairy animal husbandry. the diseases of lameness and mastitis pose substantial welfare concerns in dairy cattle and can exert adverse effects on optimal milk production. effectively monitoring and accurately anticipating the likelihood of these situations is of utmost importance. the references cited are ebrahimi et al., 2019; taneja et al., 2020; warner et al., 2020. the application of big data analytics methodologies enables the collection and integration of data from several farms, with the objective of improving the effectiveness of production processes and systems (aiken et al., 2019). the significance of big data is contingent upon the automation, accessibility, and correctness of the data being considered. in order to uphold the integrity of the data, it is imperative to incorporate error checking and quality control protocols (vanderwaal et al., 2017). in order to optimize the utilization of plf in agricultural settings, it is imperative to undertake the development of software, implementation of quality control mechanisms, establishment of database systems, and application of statistical approaches to proficiently condense and present the data. furthermore, it will be imperative to carefully choose the most appropriate data models for this objective (koltes et al., 2019). the management of extensive data gathered from agricultural operations presents notable obstacles in terms of privacy and security (wolfert et al., 2017). consequently, the current utilization of farm data collection is limited due to farmers' overriding concern for privacy preservation. by using data obtained from biometric and biological sensors, sophisticated data analysis techniques can be employed to create digital farming service systems that hold promise for enhancing animal production capacity, productivity, and livestock welfare. the development of the moocare prediction model aims to assist dairy producers in effectively managing their dairy farming operations through the utilization of internet of things (iot) sensors and big data analytics. the model proposed by righi et al. (2020) is designed to forecast milk production. in their study, gulyaeva et al. (2020) developed methodologies utilizing extensive datasets for the purpose of detecting and forecasting chicken diseases. the utilization of wearable sensors and livestock husbandry sensing systems enables the collection of digital data, which can subsequently be employed to develop precise digital fingerprints for animals. the aforementioned fingerprint can then be employed in predictive and adaptive decision-making methodologies. according to tsay et al. (2019), the three elements, footprint, fingerprint, and forecast, serve as both guiding principles for livestock producers in the management of animal production and as tools for the creation of integrated application systems pertaining to livestock value, supply, and food chains. figure 3 illustrates the utilization of sensor-based big data applications in the context of precision livestock production. a blockchain can be defined as a secure and decentralized database of transactions, wherein each transaction is associated with a distinct node (elisa et al., 2023). the nodes are organized into records, commonly known as "blocks", based on a consensus reached among the participating organizations. the blocks exhibit interconnectivity and include distinct hash codes, so establishing a sequential chain. upon the occurrence of a new transaction, a node is promptly generated, including pertinent details regarding said transaction, and subsequently appended to the blockchain (chattu et al., 2019). the core attributes of blockchain technology encompass its distributed nature, transparency, immutability, and democratic underpinnings. within the realm of livestock management, it is important to assign a distinct identification to every animal present on the farm. the distinct identification will remain associated with the animal throughout its entire lifespan, encompassing data regarding the farm(s) in which it resided, the mode of transportation utilized for transferring the animal from the farm(s) to the slaughterhouse, the veterinarian tasked with examining the animal at the slaughterhouse, the evaluation of quality subsequent to global sustainability research global scientific research 9 slaughter, the transportation of the meat product, and ultimately, particulars pertaining to the packaging and disposition of the product. figure 3. precision cattle production using sensor-based big data (neethirajan & kemp, 2021). blockchain the implementation of blockchain technology in cattle farming presents a multitude of advantages, including the facilitation of decentralized and automated transactions. this has the potential to enhance the effectiveness of auditing systems utilized by certification and regulatory authorities (akram et al., 2024). furthermore, it facilitates seamless integration of systems and effectively manages comprehensive documentation of all transactions pertaining to the transportation of animals from their farm to the dining table. furthermore, it enhances the level of traceability and openness within the cattle farm industry (picchi et al., 2019). in contemporary times, there has been a growing dearth of trust between farmers and clients due to the escalating demand for transparency in agricultural commodities. the potential of blockchain technology lies in its ability to enhance confidence among consumers through the provision of transparent and comprehensive information pertaining to the complete lifespan of an animal (patel et al., 2023). the application of blockchain technology has significant promise in facilitating the detection and surveillance of animal disease outbreaks, encompassing h1n1 swine flu, foot-and-mouth and mad cow diseases, avian influenza, and the recent surge in salmonella infections. there is an increasing level of consumer consciousness regarding the environmental and ethical dimensions associated with animal farming (raihan, 2023i). furthermore, there is a growing demand for transparency for the methodologies employed in animal husbandry. ensuring food global sustainability research global scientific research 10 safety is a significant priority for consumers. based on data provided by the world health organization (who, 2020), it is estimated that around 10% of the global population has food-related illnesses each year, leading to an annual mortality rate above 420,000 individuals. the implementation of blockchain technology has promise in enhancing the capacity to monitor and identify the source of hazardous food products, hence enhancing the traceability and accountability for problematic practices within the livestock farming industry (lin et al., 2018). an essential advantage of blockchain technology is the decentralized distribution of information among a network of users, as opposed to being centralized and managed by a single people or group. in the event of a cattle disease outbreak, producers worldwide would have the ability to securely input and retrieve disease management data. the aforementioned would empower individuals to actively participate in the management of the outbreak or equip themselves for an anticipated outbreak that could impact their agricultural operations (chattu et al., 2019). given the growing globalization of food chains and systems (raihan, 2023j), it has become imperative for animal products to adhere to various norms and standards pertaining to animal welfare and sustainability. efficient retrieval of regulatory documentation poses a challenge for regulators and third-party inspectors, particularly when such material is available in physical format or limited databases (motta et al., 2020). based on the findings of motta et al. (2020), it is evident that the cattle farm industry exhibits a relatively lower level of digitalization in comparison to other industries, suggesting a notable opportunity for advancement. the integration of blockchain technology within the realm of animal agriculture has promised in mitigating the aforementioned issues pertaining to disease outbreaks and quality assurance in food production. depicted in figure 4 is the streamlined operational framework of the system, which facilitates the provision of services to diverse users. the main objective of the quarantine department is to ensure the comprehensive verification of vaccination quarantines and the meticulous examination of health data information. in contrast, the agricultural regulatory agency is primarily concerned with the specific rules pertaining to the farming process. the environmental protection agency has expressed apprehension regarding the environmental challenges presented during the breeding process, namely pertaining to the management of breeding waste (raihan, 2023k). however, the main emphasis for farmers lies in acquiring animal breeding genetic data. it is imperative for slaughterhouses to implement a comprehensive system that facilitates the efficient management of livestock slaughter, while distributors necessitate unrestricted access to pertinent slaughter information. in order to conduct precise risk assessments, insurance organizations require comprehensive data regarding the health condition of the authorized livestock, whereas financial institutions prioritize the collection of information pertaining to farmers' assets and livestock breeding techniques. figure 4. livestock insurance's streamlined business strategy (shen et al., 2023). global sustainability research global scientific research 11 notwithstanding its manifold benefits, blockchain technology is now in its nascent stages of advancement for widespread implementation in the food industry, with a restricted body of study investigating its impact on livestock farming (picchi et al., 2019). bioengineers and data scientists possess the potential to make substantial contributions towards the establishment of precise criteria for the selection of the most efficient blockchain solution tailored to the unique requirements of various companies within the cattle production sector. conclusions the primary objective of this review article is to examine plf technologies, which are designed to optimize livestock production while addressing client concerns. the technological approaches investigated in this study encompass biometric sensors, big data analysis, and blockchain technology. the use and integration of plf technologies have the potential to address the growing apprehensions among consumers pertaining to animal welfare, environmental sustainability, and public health. furthermore, it can also contribute to addressing the increasing need for animal-derived goods as a result of the growing global population. biometric sensors facilitate the collection of real-time data pertaining to the welfare and state of animals, thereby empowering farmers to adopt proactive management strategies that promote sustainable and secure food production. big data analysis is a process that transforms sensor data into valuable and applicable outcomes for agricultural operations. the utilization of blockchain technology in animal husbandry serves to augment transparency and traceability, hence fostering heightened customer confidence and enhancing food safety measures. nevertheless, the application of plf technology in animal agriculture is presently in its nascent phase, necessitating the resolution of various obstacles prior to the widespread adoption of these technologies by farmers and consumers on a global scale. the realization of a society that is both digitally inclusive and robust, facilitated by the implementation of novel digitalization methods in cattle farming, necessitates the active involvement and engagement of citizens in the collaborative process and endorsement of technical advancements. declaration acknowledgment: n/a funding: this research received no funding. conflict of interest: the authors declare no conflict of interest. ethics approval/declaration: n/a consent to participate: n/a consent for publication: n/a data availability: n/a authors contribution: homaira afroz himu and asif raihan contributed to conceptualization, visualization, methodology, reviewing literature, extracting information, synthesize, and manuscript writing. global sustainability research global scientific research 12 references aiken, v. c. f., dórea, j. r. r., acedo, j. s., de sousa, f. g., dias, f. g., & de magalhães rosa, g. j.

digital economy; financial development; lcc hypothesis; mmqr approach introduction the urgency for improving the standard of ecological sustainability across national, regional, and global economies has attracted attention in recent years from policymakers and researchers (ibrahim & ajide, 2021, raihan et al.2024a). it has been recognized that one vital cause of climate change is greenhouse gas emissions (atasoy, 2017; global sustainability research global scientific research 28 destek and sarkodie 2019, islam et al.2023). about 75% of global emission statistics are attributed to carbon dioxide (co2) emissions, making it among the primary contributors to ghg emissions (diffenbaugh, 2020, pattak et al.2023). a reduction in emissions of less than 25% and 55%, respectively, must be achieved to meet the goal of reducing climate change to less than 2 °c and 1.5 °c by 2030 (unep, 2019, raihan et al.2022a). to prevent devastating global climatic catastrophes, cop26 suggested that all nations aggressively embrace equitable growth methods and keep global temperature change to 1.5 °c (murshed, 2021, raihan et al.2023a). the seven nations considered vital for preserving a high standard of living in the world's economy are japan, the us, canada, italy, germany, france, and the uk (saeed et al., 2024, voumik and ridwan, 2023). several factors led to the selection of g-7. for example, the g-7 territory produces more than 60% of the globe’s net financial assets as a consequence of their considerable economic endeavors (alola et al., 2022). then, the group's total usage of energy accounts for over 42% of global energy use (world bank 2017). then, through its annual conference, the group of seven has devoted itself for the past 20 years to developing green technology and reducing the generation of waste (kirton, 2012, raihan et al.2023b). fourth, environmental damage remains an imminent threat to the g-7 countries, even with their advancement toward a sustainable economy (khan et al., 2020). for example, the group produced around 38% of the total global emissions between 1960 and 2014 (world bank 2017). canada holds the greatest per capita energy use and ghg pollution among the g7. the country's performance regarding environmental policy is assessed as average because it continues to offer incentives for the use and extraction of fossil fuels. in terms of power consumption and release of greenhouse gases, the uk, italy, and germany do exceptionally well, while the usa and japan perform quite poorly (hao et al., 2020, raihan et al.2022b). the non-homogeneous features of the nation make the representation seem fascinating. the findings of this research could assist the leading nations develop appropriate environmental strategies. the g-7 nations, which have created complex nations, are growing remarkably in response to technological advances and changes in society (balsalobre-lorente et al.,2024). these economically advanced countries possess more complicated economies than other countries (khan et al., 2022, ridwan, 2023). the load capacity factor (lcf) is a substitute for the ecological condition in this work, which relies on conclusions from previous examinations by wang et al. (2024), voumik et al. (2024), awosusi et al. (2022), and shang et al. (2022). a detailed look at the needs imposed on air, land, and water by human beings, as well as the ability of earth's resources to meet and adapt to such demands, is made feasible by the lcf. one technique for assessing how sustainable human activity is concerning the earth's carrying capacity is the ecological footprint (efp) accounting (wackernagel & rees, 1998; hoekstra, 2009). ecological footprint (efp) and biocapacity are both of its components (mir et al., 2022). environmental deterioration puts the well-being of almost 80% of the world's population at risk (wu et al., 2024). the past ten years have witnessed notable gdp expansion and achievement, especially in developing nations. this has placed a growing strain on ecological systems, resulting in biodiversity loss and a spike in greenhouse gas emissions (esmaeili et al., 2023; ayad et al., 2023; yameogo et al., 2021). numerous opportunities through which the financial sector might impact environmental quality have been discovered by previous research. for instance, liberalization of finance increases the volume of money that consumers and companies must allocate and consume, which results in a spike in pollution (bekhet et al., 2016; awosusi et al., 2021); and financial accessibility promotes excessive energy usage and investments in green technologies, which enhances green environment (tamazian & rao, 2010, ridzuan et al.2023). with the development of iot, ai, virtual reality (vr), blockchain, autonomous vehicles, and modern technologies, the digital economy is expected to become indispensable (javaid et al.,2022; tolstykh et al., 2019). strong online payment verification is one example of how digital technologies have simplified transactions (castelo-branco et al., 2019). out of the three categories, ecological sustainability has the highest opportunity to reap benefits from ai, with 93% of the sdg targets being positively impacted (vinuesa et al., 2020, urbee et al.2024). ai might global sustainability research global scientific research 29 positively affect 79% of the sdgs. the intergovernmental panel on climate change (ipcc) highlighted that global pollution must drop to net zero by at least 2050 to preserve a "high confidence" level of limiting warming to manageable degrees (masson-delmotte et al., 2018). by 2030, ai-powered technologies are projected to help reduce worldwide emissions by 4% (gawel & herweijer, 2021, voumik et al.2023a). according to certain research, urban environmental sustainability advances the digital economy (ulucak & khan 2020; shobande & ogbeifun 2021; mondejar et al. 2021). however, ecological sustainability might decline as a result of the digital economy (cheng et al. 2019; avom et al. 2020). by connecting all aspects of business across the internet, moriset and malecki (2009) contend that the dge lessens reliance on physical locations. with this background in mind, our investigation aims to figure out how the g-7 countries (canada, france, germany, italy, japan, the united kingdom, and the united states) are affected by financial development (fd), artificial intelligence (ai) innovation, gdp growth, and the digital economy (dge) sing mmqr approach from 1990 to 2018. moreover, the dkse, amg, and ccemg methodologies were employed to verify the reliability of the results. the motive is to deliver advanced ideas of the multifaceted relationships between these components while supporting the emergence of ecologically friendly methods and stable economic development in this region. in financial development, this investigation fills the need for more information about the lcf in the g-7 nations in light of ai innovation and the digital economy. previous research highlighted the impacts of digitalization, emerging technologies, and globalization in finance on lcf. other nations or areas have conducted multiple studies on lcf and associated variables. this research adds uniqueness to the g-7 economies instance. as far as we are aware, the experiment we undertook is the initial effort to conduct a thorough analysis of the literature on the lcf, and its significance comes from the fact that ai and dge have not received much attention in previous research projects. policymakers and strategy developers may be able to foster environmentally conscious behavior more effectively if they are aware of these elements. the other part of this study falls into five sections. section 2 covers the body of current literature. in part 3, we go over the data, method, and modeling. section 4 provides research outcomes and discussions. finally, section 5 reports its conclusion and suggestions for policymaking. literature review in various regions of the world, the complex interrelationships among ecological footprint, clean energy use, urbanization, and financial globalization have been the subject of several ongoing researches. we want to emphasize the innovative sides of our research, which we believe add value to this area of inquiry that is consistently expanding. as a result, the findings of previous studies that have shed light on the factors influencing economic growth, financial development, artificial intelligence (ai), urbanization, the digital economy, and environmental sustainability in the group-7 countries have been compiled into six sub-sections within this component. since early economies prioritized increased production as a basis for the betterment of people, economic growth and a sustainable ecosystem are strongly connected (kihombo et al.,2022, voumik et al.2023b). global researchers have been paying careful consideration to the link that exists between economic development, structural change, and environmental pollution in recent years (dong et al., 2020). environmental deterioration was revealed to be a result of higher gdp by xue et al. (2022) utilizing the ardl approach. in a similar vein, bekhet al. (2017) observed that in saudi arabia, oman, qatar, and bahrain, gdp development is linked to greater co2 emissions. additionally, the findings that a 1% increase in the italian gdp over a longer period might turn into an 8.08% increase in co2 pollution (pattak et al.,2023). multiple investigations also agreed with this outcome, such as ali et al.(2020) in malaysia, voumik et al.(2023c) in kenya, ahmed et al.(2015) in pakistan, ahmed et al.(2020) in china and saud et al.(2018) in bri countries. nevertheless, based on research conducted in the g-7, balcilar et global sustainability research global scientific research 30 al. (2018) assert that environmental quality in germany and the uk is unaffected by growth in the economy. however, ridwan et al. (2024) claim that both in the short and long run, gdp significantly lowers co2 emissions in six south asian economies. raihan et al. (2024b) found that economic expansion somewhat reduced carbon dioxide emissions in their examination of the link between gdp growth and co2 emissions in india. similarly, bento and moutinho (2016) examined data for italy from 1960 to 2011 using the ardl technique and determined that gdp development lowers pollution levels in italy. moreover, mehmood et al. (2023) examined the gdp stimulus of the group of seven area's efforts to reduce greenhouse gases from 1990 to 2020. this cs-ardl study shows an inverse association between gdp and co2 emissions. the term artificial intelligence refers to automated cognition that was developed in the 1950s and has discovered effective applications in research as well as business (hoang et al., 2022). artificial intelligence (ai) can encourage sustainability across multiple sectors by reducing waste products, increasing asset availability, and delivering green solutions (rakha, 2023). blockchain technology and artificial intelligence (ai), in particular, can significantly sever the link between economic expansion and its detrimental effects on the natural world (jiang et al., 2021; meng and zhao, 2022; tsolakis et al., 1523). there are several advantages of using ai-powered sensors and equipment for real-time hazardous substance monitoring in-ground and plant matter (singh & kaur, 2022). initially, in contrast to conventional experimental techniques, it enables the more accurate and consistent recognition of these chemicals. second, it provides information in real time, allowing fast reactions to any potential contamination problems. finally, it decreases the requirement for manual collection of information and analysis, which lessens manpower and improves the monitoring of the accuracy of processes (jeong and choi, 2022). alsharafi et al. (2023) gathered information from malaysia and turkey to explore the factors influencing the adoption of ai products and their effect on environmental conditions. they found that while ai solutions can reduce expenses, conserve water and energy, and enhance the disposal of waste, their influence on environmental sustainability is rather small, especially in emerging territories. stakeholders can offer the framework for making sensible choices, putting effective methods into practice, and developing strategies that encourage ecological sustainability through using ai and aiot technologies (bibri et al., 2024). moreover, governments can promote openness, authenticity, and accountability in the manufacturing process by utilizing technology and ai. this will help to promote sustainable practices and lessen adverse environmental impacts (hong and xiao, 2024). environmental sustainability and financial development are connected in a complicated way, and financial progress can lead to environmental damage in certain instances. nonetheless, robust regulatory bodies and their consistent green initiatives might lead to enhanced environmental standards and a healthier economic system (birdsall and wheeler 1993). most research shows an adverse link between a sustainable environment and financial growth. however, numerous studies also found a positive link based on associated variables, including the nature of the industry, country classification, and financial system in the economy (lyu et al., 2021; usman et al., 2021; zafar et al., 2019). according to shahbaz (2013), in pakistan, environmental degradation might worsen as a result of financial uncertainty. by organizing countries into three income categories, nasreen and anwar (2015) discovered that, within the low-income panel, financial development (fd) increased damage to the environment, while in the high-income panel, it declined. according to sharma et al. (2020), rising asian nations' environmental impacts are positively influenced by financial growth. in addition, by raising the ef, financial development causes environmental damage in emerging regions (ahmad et al., 2022). as per certain analyses (zhang, 2011; shahbaz et al., 2016), expansion in finances protects the level of the ecosystem by reducing emissions of greenhouse gases. using ols, pqr, and ccemg methodologies, ali et al. (2023) reviewed the effects of financial development on the ecological health of the e-7 bloc. they concluded that the region's environmental deterioration is exacerbated by financial development. financial growth, based on lv and li (2021), can enhance the level of biodiversity, specifically in areas where it becomes more expanded and developed. global sustainability research global scientific research 31 furthermore, shoaib et al. (2020) observed that financial expansion had an uplifting impact on co2 emissions in g8 and d8 territories employing the pooled mean group technique. however, dogan and turkekul (2016) illustrated that monetary improvement is not a factor in the us's ecological degradation. the term "digital economy" refers to economic activity, including online transactions across various platforms and technologies, including mobile, large-scale data, the internet, and information and communications technology (javaid et al.,2024). many investigations on the financial and social implications of dge have been conducted by academics. from a small-scale perspective, dge might reduce both the degree of information asymmetry and alleviate businesses' financial limitations by utilizing modern digital technologies. liu (2023) suggests that the expansion of the dge may have a moderating implication on discharges of pollution. raihan et al. (2024c) conducted research in the g-7 region from 1990 to 2019 to check the consequences of dge on carbon emission. utilizing the ardl model showed that the digital economy significantly promotes a green ecosystem. jiang et al. (2024) illustrate that the digital economy ensures environmental sustainability and can cut emissions by up to 0.092 %. yuan et al. (204) adopted the spatial econometric model based on panel data from 267 chinese cities from 2012 to 2021. they found that dge could significantly lower harmful emissions. similarly, several studies in different areas also found that (ma et al.,2024; dong et al.,2022; bai et al.,2022; che and wang, 2022; li et al.,2022). the influence of a shared digital economy on environmental pollution is yet unknown (jin et al.,2018). according to kuntsman and rattle (2019), the improvement, maintenance, and disposal of modern innovative technologies have all had a substantial detrimental impact on natural health. according to zha et al. (2022), the growth of the digital economy can successfully enhance the environmental sustainability of neighboring cities while simultaneously mitigating the co2 pollution intensity of a particular region. in developing nations, dge increased carbon emissions, based on danish et al.(2019), who used information from 73 countries and the modified ordinary least squares (ols) approach. the phenomena of urbanization have a noteworthy implication on the condition of the natural world. the greater need for energy, resources from nature, and additional services generated by urbanization will eventually have a detrimental impact on the ecosystem. numerous authors, such as arshad et al. (2020) for asian economies, nathaniel et al. (2021) for latin american and caribbean countries, van et al. (2018) for australia, and mahmood et al. (2020) for saudi arabia, have explored the link among urbanization, ghg emissions, and the environmental impact. arslan et al.(2022) indicated that urban population expansion accelerates ecological deterioration. for asean nations, nathaniel and abdul (2020) investigated the link between urbanization and ecological footprint (efp) between 1990 and 2016. according to their research, urbanization increases the efp, which reduces environmental sustainability. utilizing unique panel data approaches from 2000 to 2020, feng and li (2024) demonstrated that urbanization continues to be a leading element in rising ecological degradation in the asean6 economies. surprisingly, xue et al. (2022), utilizing the ardl approach, discovered that urbanization reduced pollution in the third-largest european country, france, from 1987 to 2019. ahmad et al. (2021) demonstrated that urbanization improves ecological sustainability by lowering the ecological footprint, especially measured by fmols and dols. mehmood (2021) discovered that urbanization in the saarc area increased air quality between 1996 and 2015. moreover, azam and khan (2016) investigated how urbanization affected environmental degradation in bangladesh, india, sri lanka, and pakistan between 1982 and 2013. the outcomes showed that, while there was a negative correlation in bangladesh and india, there was an encouraging correlation in sri lanka and pakistan between urbanization and environmental degradation. the methods of knowledge accumulation related to the digital economy (dge), artificial intelligence (ai) innovation, and the real effect of financial growth on load capacity factor (lcf) remain unclear, regardless of the g-7 nations' promising sustainable environment quality. from the standpoint of the g-7, aspects like artificial intelligence (ai), the digital economy, and financial development are entirely novel fields of investigation. global sustainability research global scientific research 32 furthermore, the mmqr approach, which has not been widely implemented in prior llc studies, is used in our work. this approach enables the effective assessment of data from panel models, consequently augmenting the discipline's methodological understanding. through an analysis of all of these standards, the nations selected can assess whether harnessing innovations in technology, economic collaboration, and sustainable growth may offer the possibility to improve their sustainability issues. therefore, by examining the dynamic impacts of gdp, dge, fd, and ai on lcf and employing different advanced econometric methodologies, this present study intends to close the deficiency in the literature for the instance of group seven nations. methodology data and variables the research gathers yearly data for the g-7 from four sources for the years 1977–2018. our world in data indicates that the digital economy indicates ict goods imports (% of total goods imports), and artificial intelligence reflects patent applications in the field of ai. the world bank provided the statistics used to calculate gdp and gdp2, which are expressed as (current us$). the load capacity factor (lcf) (biocapacity/ecological footprint) is derived from data from the global footprint network. lastly, the imf's financial development index is a collection of financial development data. table 1: data and variables variables description logarithmic form unit of measurement source lcf load capacity factor llcf gha per person gfn gdp gross domestic product lgdp current us$ wdi gdp2 gross domestic product square lgdp2 current us$ wdi ai artificial intelligence innovation lai patent application in ai field our world in data fd financial development lfd financial development index imf dge digital economy ldge ict goods imports (% of total goods imports) our world in data urba urbanization lurba urban population (% of total population) wdi theoretical framework the lcc theory is based on the lcf indicator, which takes alternatives for environmental provision and manmade needs for the environment into account. the lcf initially appeared in the literature by siche et al. (2010), and pata (2021) was the very first to do empirical studies on the variables that influence the lcf. by differentiating the ecological footprint and biocapacity, the lcf enables thorough environmental quality assessment (dogan and pata,2022). the lcf enables both the supply and demand sides to examine the ecosystem, and a more favorable global sustainability research global scientific research 33 environment is shown by a higher lcf (pata and kartal, 2023). scholars have developed advanced techniques to measure the implications of manmade activities on ecology and evaluate how long the planet will survive these effects. with the use of these methods, the lcc evolves into an invaluable instrument for integrating intricate data into an accessible framework by considering the association between human actions and the clean environment. the components of gdp growth, financial development, artificial intelligence (ai), urbanization, digital economy, and load capacity factor may be related in several ways, as already mentioned. for the lcc hypothesis, we have developed the following equation (1) to expand our understanding of prior studies: load capacity factor = f(gdp, gdp2, kt) (1) here, kt is a factor for additional parameters impacting the lcf, while gdp is a variable for income in equation (1). equation (2) tries to illustrate a broader understanding of the elements impacting the lcf. lcf = f(gdp, gdp2, ai, fd, dge, urba) (2) while the labels financial development (fd), artificial intelligence (ai), urbanization (urba), and digital economy (dge) serve to depict particular concepts, the load capacity factor in equation (2) is portrayed by lcf. an econometric explanation of this equation is provided below. lcfit = ρ0 + ρ1gdpit + ρ2gdpit 2 + ρ3aiit + ρ4fdit + ρ5dgeit + ρ6urbait (3) the logarithmic outcomes of the elements are displayed in equation (4), which improves interpretation and simplifies the formulation of statistical findings. these transformations can deal with heteroscedasticity and accept information with various magnitudes, making them effective in reducing the implications of data with an extensive range. moreover, the research's coefficients are represents in the parameter range of ρ0 to ρ6 in equation (4). lcfit = ρ0 + ρ1lgdpit + ρ2lgdpit 2 + ρ3laiit + ρ4lfdit + ρ5ldgeit + ρ6lurbait (4) econometric framework the link between lcf and some independent factors in the g-7 nations was investigated in this study using the mmqr approach for data estimation. we additionally employed the dkse, amg, and ccemg approaches to guarantee robustness. to begin with, we checked for dependence and stationarity using the csd and panel unit root analyses. we subsequently carried out the cointegration and mmqr estimation. finally, the d-h causality method was utilized to determine the causal links among the selected factors. cross-sectional dependence test cross-sectional dependence (csd) can arise from unidentified reasons that distort the correct values, thereby decreasing the usefulness of panel data. when the csd problem is avoided in panel data, can end up in misleading outcomes (waris et al., 2023). as countries grow increasingly integrated and dependent on one another, industrialization is making csd a greater problem in panel data (de hoyos and sarafidis, 2006). our study will initially utilize the csd testing created by pesaran (2015) in each cross-sectional unit to predict the existence of csd before starting the empirical portion of the investigation. so, in order to illustrate the test’s statistics, the below equation can be taken: global sustainability research global scientific research 34 𝐶𝑆𝐷 = √ 2𝑇 𝑁(𝑁−1)𝑁 (∑ ∑ 𝐶𝑜𝑟𝑟𝑖,𝑡 ̂𝑁 𝐾=𝑖+1 𝑁−1 𝑖=1 )……………………… (5) panel unit root test we used the llc test, developed by levin et al. (2002), and the second-generation panel unit roots assessment, introduced by pesaran (2007), taking into account any potential cross-sectional independence within the panel time-series information. these tests include the cross-sectional augmented dickey-fuller (cadf) panel unit root tests and the cross-sectional ips (cips), which is an extension of the ips panel unit root test that was established by im et al. (2003). based on the alternative hypothesis that at least one individual series in the panel is stationary and the null hypothesis that all individual series within the panel are stationary, the cips and cadf panel unit root methods are conducted (ssali et al.,2019). the llc test statistics can be displayed in the following way: ∆yit = 𝛽𝑖yit−1 + ∑ dij∆yit−1 + mit ′ φϑi j=1 + μit ………………………….(6) here, 𝑀𝑖𝑡 ′ represents the column vector of the independent variable and in regression 𝜑 denotes the vector of parameters. by incorporating heterogeneity in the coefficient of yi,t−1, im et al. (2003) expanded the llc test and introduced a test strategy named the ips unit root test that utilized the mean of each participant's unit root statistics. the equation underlying the ips unit root test is as follows: δyi,t = βi + γi,t + δyi,t−1 + ∑ θk∆yi,t−j + μi,t k j=1 (7) in contrast to traditional unit root tests, pesaran's (2007) novel approach, cips, enables heterogeneity resilient to csd and provides more consistent and trustworthy findings (harris and tzavalis 1999; im et al. 2003; levin et al. 2002). the cips test is examined using equation (8): 𝐶𝐼𝑃𝑆 = 1 𝑁 ∑ 𝑡1(𝑁, 𝑇)𝑁 𝑡=1 ……………………………… (8) where n means a cross-sectional aspect, and t means time series dimension. moreover, equation (8) provides the following method for computing the cadf: ∆𝑌𝑖𝑡 = 𝛿𝑖 + 𝜌𝑖𝑌𝑖𝑡−1 + 𝛿𝑖�̅�𝑡−1 + ∑ 𝜔𝑖𝑗�̅�𝑡−1 𝜗 𝑗=1 + ∑ 𝛼𝑖𝑗 𝑝 𝑗=1 ∆𝑌𝑖,𝑡−1 + 휀𝑖𝑡 … … … (9) where �̅�𝑡−1 and ∆𝑌𝑖,𝑡−1 symbolize the average values of the cross-sectional analysis for both the first difference and lag. panel cointegration test the pedroni panel cointegration examination is utilized to check if cointegration prevails, assuming panel heterogeneity (raihan et al.,2024). pedroni's (1999) panel cointegration test is utilized in this work, which has two separate assessments. panel v-statistics, panel rho-statistics, panel pp-statistics, and panel adf-statistics are the global sustainability research global scientific research 35 four statistical measures used in the first test, which uses a within-dimension method. group rho-statistics, group pp-statistics, and group adf-statistics are the three statistical measures used in the second test, which employs a between-dimension technique. both the homogeneous (panel) and interdimensional (group) versions of pedroni's statistics are of the adf and pp categories (lugo-arias et al., 2024). the null hypothesis that there exists no cointegration is rejected if the majority of these data have p-values that are less than a predetermined significance threshold. the general regression residuals for the proposed co-integration regression are provided below: 𝑦𝑖,𝑡 = 𝜔𝑖 + 𝛿𝑖𝑡 + 𝜌1𝑖𝑥1𝑖,𝑡 + 𝜌2𝑖𝑥2𝑖,𝑡 + ⋯ + 𝜌𝑀𝑖𝑥𝑀𝑖,𝑡 + 휀𝑖,𝑡………………………………. (10) for, t = 1,…..t; i = 1,…, n; m = 1,…, m the null hypothesis of the no-cointegration test is denoted as 𝐻0 : 𝑓𝑖 = 0; ∀𝑖 (absence of cointegration). method of moments quantile regression this study uses machado and silva's (2019) invention, the moments' regression approach (mm-qr), to determine the quantiles. in contrast to conventional quantile regressions, the mmqr evaluates the objectives by modifying the mean values, allowing "conditional heterogeneous covariance implications" by koenker (2004) and canay (2011) to affect and accomplish the dependent variable's obtaining over the whole data distribution. furthermore, this technique allows for location-dependent imbalance as the variables are sensitive to their position within the distribution circumstances (hieu and mai,2023). all these suggest that the mmqr is more acceptable and robust, especially when it comes to addressing the issues of heterogeneity and endogeneity (an et al., 2021) and developing asymmetrical nonlinear associations (elbatanony et al., 2021). the alternative model is listed as follows: 𝑌𝑖𝑡 = 𝛽𝑖 + 𝑋𝑖𝑡𝛾 + (𝜗𝑖 + 𝑍𝑖𝑡𝜑)𝑈𝑖𝑡………………………..(11) where the probability is 𝑃 {𝜗𝑖 + 𝑍𝑖𝑡𝜑 > 0} = 1. additionally, parameters such as 𝛽, 𝛾, 𝜗, and 𝜑 are required to be calculated. moreover, in 𝛽𝑖, 𝜗𝑖𝑖 = 1…….., n denotes ‘individual fixed effect, and z represents the k vector of component x”. furthermore, the elements are transformed with component m given below: 𝑍𝑚 = 𝑍𝑚 (𝑋), 𝑚 = 1, … … … , 𝑘………………………(12) here, 𝑈𝑖𝑡 is orthogonal to 𝑋𝑖𝑡 and consistent in fulfilling the moment conditions, which do not include stringent heterogeneity. hence, the conditional quantile of y is mentioned below: 𝑄𝜏 ( 𝜏 𝑋𝑖𝑡 ) = (𝛽𝑖 + 𝜗𝑖𝑞 (𝜏)) + 𝑋𝑖𝑡𝛾 + 𝑍𝑖𝑡𝜑𝑞(𝜏) ………………….(13) in this equation, 𝑋𝑖𝑡 symbolizes the predictive variables such as gdp, 𝐺𝐷𝑃2, ai, fd, dge, and urba. on the other hand, 𝑌𝑖𝑡 represents the dependent variable like lcf. it's important to keep in mind that changing the intercept does not take into account a person's influence when ols is utilized, and a consequence comes from fixed effects. now, 𝑄(𝜏) can be estimated as follows: 𝑀𝑖𝑛𝑞 = ∑𝑡∑𝑖 𝑝𝜏(𝑅𝑖𝑡 − (𝜗𝑖 + 𝑍𝑖𝑡𝜑𝑞))…………….(14) robustness check this phase involves performing three separate tests: the dkse introduced by driscoll and kraay (1998), the amg estimator created by bond and eberhardt (2009) and eberhardt and teal (2011), and the ccemg estimator introduced by pesaran (2006). in contrast to traditional standard errors, dkse takes into consideration slope global sustainability research global scientific research 36 heterogeneity, average csd, and correlated errors that might occur between observations. this helps to reduce the possibility of biases and inefficiencies during parameter estimation (ridwan et al., 2024). because of the slope of heterogeneity and the csd problem, we thus utilized the amg estimator in line with nathaniel et al. (2020); and murshed et al. (2021). furthermore, because amg considers the endogeneity issues and calculates the elasticity of particular nations, it offers several advantages over conventional panel methodologies (isik et al., 2021). in addition, findings are better suited when the time exceeds the cross-sectional unit (shahzad and aruga, 2023). the identification challenge is resolved by the ccemg by taking into consideration temporal variations with various pitch variables (raihan et al.,2024). the amg is a specific way of treating ccemg that takes into account yearly inefficiency and neglected aspects in addition to cross-dependence, heterogeneity, and structural and technology developments (polcyn et al., 2023). d-h causality test causality tests are necessary to determine the consequences of particular policies that address environmental pollution. granger (1969) established an assessment for assessing the elements' causal connections. in our present work, we utilize the d-h panel causality examination, an advanced measure of causality that was created by dumitrescu and hurlin (2012). this method is extremely comprehensive and beneficial in producing reliable outcomes throughout csd as it allows for both n > t and t > n samples (ahmed and le, 2021). according to dumitrescu and hurlin (2012), the alternative hypothesis asserts that there is at least one granger causality relationship between cross-sections, while the null hypothesis claims that there is no granger causality link between cross-sections. the causality of the d-h panel may be written as: yit = θi + ∑ δi j yi(t−j) + ∑ γi j xi(t−j) + j j−1 j j−1 εit (15) here, x and y represent the observables, δi j represents the autoregressive parameter, and γi j denotes the estimations of the regression coefficients results and discussion summary statistics based on 91 observations, the summary statistics for the factors we explored can be seen in table 02 below. a total of seven factors are presented in the g-7 nations' descriptive statistics: llcf, lgdp, lgdpsq, lai, lfd, ldge, and lurba. all of the chosen variables—aside from llcf and lfd—have positive means, as the table illustrates. furthermore, each variable's estimated standard deviation is small, suggesting that the data points are mostly concentrated around the mean with minimal fluctuation. while lfd and lurba suggest negative skewness, a lot of variables show positive skewness. the jarque-bera normality assessment was applied to establish that all the variables had a normal distribution that took skewness and kurtosis into consideration. cross-sectional dependence test to confirm if the csd is present in our data set or not, table 03 displays the results of the csd assessment. the csd statistics for all variables are regarded as statistically significant at conventional levels because of the extremely low p-values. all variables have p-values of 0.000, except lfd, where the p-value is 0.043. taken together, these data provide strong evidence of cross-sectional correlation at the 1% level. it indicates that our data collection contains a csd problem. thus, we may infer that there is a cross-sectional dependence problem with lnlcf, lngdp, lngdp2, lnai, lnfd, lndge, and lnurba. global sustainability research global scientific research 37 table 2: summary statistics of the variables

assessments were the first-generation unit root methods, and the cips and cadf analyses were the second-generation unit root tests employed in this investigation. lai, lfd, and ldge are the only ones that show stationary behavior at the level form i(0), based on the llc test findings. at the 1% significance threshold, all of the remaining elements are significant and stationary at the first difference form i(1). the results of the ips test suggest all other variables are stationary at the first difference form, except lfd and ldge. on the other hand, lfd and ldge are significant at the 1% and 5% levels of significance, respectively, and stationary at the level form. the other factors (llcf, lgdp, lgdp2, lfd, and lurba) are stationary at the first difference form i(1) and significant at the 1% level of significance, according to the cips test, while lai and ldge are stationary at the initial level and significant at the 5% level of significance. comparably, the cadf unit root test reveals that all variables, except for lai and lfd, which are stationary at the level form i(0) and significant at the 5%, are stationary at the first difference form i(1). therefore, before we considered their initial differences, lcf, gdp, gdp2, and urba were not stationary; as a result, they became global sustainability research global scientific research 38 stationary in all four unit root evaluations. conversely, in the level form i(0), lai, lfd, and ldge are stationary. we can move on with the assessment utilizing the mmqr framework because of this mixed order of integration.

distinct sets of alternative hypotheses are evaluated in the test: one for common autoregressive coefficients within and one for individual autoregressive coefficients between dimensions. the panel rho-statistic is positive but not statistically significant; in addition, the panel v-statistic is positive but not statistically significant, indicating mixed proof for cointegration. nonetheless, the extremely significant panel pp and panel adf-statistic results provide strong evidence to reject the null hypothesis that there is no cointegration. the null hypothesis that there is no cointegration across panels is strongly rejected by the group pp and group adf-statistic, which are both considerably negative. under the assumption of individual autoregressive coefficients between dimensions, the group rho-statistic is positive but not significant. the analysis shows that there is still an indication of cointegration throughout the variables in the overall dataset, even in the context of considerable disparities in autoregressive coefficients within and across aspects. table 5: panel cointegration test alternative hypothesis: common ar coefs.

(2021) for south korea, orhan et al. (2021) on india, ridwan et al. (2023) linked to france, ahmad et al. (2024) regarding china, pata and samour (2023) in france, and adebayo and rjoub (2021) in terms of the mint areas. additionally, destek et al. (2020) discovered that in the g-7, higher gdp is associated with increased emissions of co2 and expressed that greater economic activity which usually entails burning fossil fuels for energy is a direct result of economic expansion. furthermore, chien et al. (2023) have shown that growth in the economy often increases people's financial resources, which raises consumption levels and degrades the environment in the g-7 region. however, some authors disagree with this consequence and reveal that development in gdp can upgrade the environmental quality (voumik et al., 2022; nica et al., 2020). the coefficient of lgdp2 is positively significant at all quantiles. our findings of lgdp2 illustrate that financial expansion over time recovers environment pollution by adopting clean power and utilizing technology into manufacturing process. the finding aligns with the outcome of bunnag (2023) for thailand. there is a substantial and encouraging relationship between artificial intelligence (lai) and llc in all quantiles. ai innovation creates better opportunity for individuals to use green technology and highlights the utilization of technologies for green ecosystem. by modernizing china's manufacturing facilities, ai can have an advantageous systemic impact on lowering the intensity of environmental pollution (zhao et al.,2023). the use of ai technology in ecological damage prevention was also highlighted by ye et al. (2020). moreover, in all quantiles, the digital economy is inversely and significantly related to lcf. this indicates that a digitalized economy is not good for ensuring a sustainable environment in the g-7 area. wang et al. (2022) show that china's co2 pollution might mitigate as long as the digital economy grows. similarly, usman et al. (2021) align with this conclusion in certain asian countries. however, raihan et al.(2024) opposed this conclusion and revealed that in g-7 countries, dge improves environmental sustainability. moreover, by influencing residential energy decision-making and individual ecologically conscious actions, digital technology can decrease energy use and encourage ecologically sound growth (chiabai et al., 2013; bastida et al., 2019). conversely, lfd beneficially affects llcf, which indicates that it promotes a clean environment, and the outcomes are significant at 1% across all quantiles. this conclusion conflicts with those of (xu et al., 2018) in saudi arabia, ahmad et al. (2022) in 17 developing nations, weili et al.(2022) in the belt and road countries, and shehzad et al. (2022) in pakistan. on the other hand, durani et al. (2023) revealed that financial development causes ecological destruction in brics nations. furthermore, ibrahim et al. (2023) proposed that the brics countries' ecosystem condition declines due to financial growth. lastly, from the table, we can see that urbanization is negatively associated with the lcf variable across all quantiles. this outcome indicates the necessity of sustainable urban planning for the sustainable environment of the chosen area. furthermore, urba stresses ecosystems by causing forest loss, the loss of agricultural area, and the production of hazardous waste (winoto and schultink, 1996). the conclusions seem consistent with those of anser et al. (2020), azam and khan (2016), and gasimli et al. (2019). however, kim (2020) discovered that korea's rebound effect and high energy efficiency imply that urba has no impact on pollution.

note: standard errors in parentheses, *** p<0.01, ** p<0.05, * p<0.1 robustness check the dkse, amg, and ccemg evaluations, which were performed to confirm the reliability of our estimations, can be seen in table 7. we examine the implications of gdp, gdp squared, urbanization, digital economy, artificial intelligence (ai), and financial development (fd) on lcf. the findings support the conclusions from the mm-qr regression, indicating that lcf significantly decreases as gdp per capita increases. specifically, the estimators dkse, amg, and ccemg show a decline in lcf of approximately 0.168%, 0.177%, and 0.210%, accordingly, for a 1% expansion of gdp. on the other hand, economic development over time leads to a spike in lcf by 0.209% (dkse), 0.294% (amg), and 0.139% (ccemg), which is in line with the results of the mm-qr regression. similarly, a 1% rise in ai causes a boost in lcf by 0.126% in dkse, 0.042% in amg, and 0.019% in ccemg. this conclusion highlights the favorable consequence of ai technology on environmental sustainability in the g-7 region and is consistent with the mmqr analysis. additionally, the dkse, amg, and ccemg estimators demonstrate an upward correlation between financial development and lcf, with a 1% increase in fd interpreting into a rise in lcf of 0.637%, 0.629%, and 0.650% in the group-7 region. these results are consistent with the results of the mmqr method. on the other hand, the digital economy is unfavorably related to lcf in dkse (−0.096), amg (−0.065), and ccemg (−0.289), with a 1% significance level for the first two estimations. these findings, in addition to those from the mm-qr regression, corroborated the idea that the adoption of the dge degrades environmental quality. differential effects of urbanization on lcf are observed in dkse, amg, and ccemg. at the 5% level of significance, the urbanization coefficient in dkse (-0.124) and amg (-0.842) is detrimentally significant. conversely, the ccemg calculation displays that the coefficient is destructively significant (−0.844) at the 10% significance global sustainability research global scientific research 41 threshold. the above findings confirm the adverse influences of urban population increase on ecosystem conditions in the g-7 countries and are following the mmqr technique. table 7. robustness test (1) (2) (3) variables dkse amg

hurlin causality assessment results are summarized in table 8. we could reject the null hypothesis as the research shows unidirectional causation between lgdp and llcf, and the corresponding pvalue is below the traditional significance thresholds. similarly, with a p-value of 0.0197, lgdp2 granger causes llcf, suggesting that faster economic development has a major effect on lcf in the g-7 region. furthermore, the p-value for lai is 0.0017, which is under the accepted 0.05 significance threshold. we might therefore infer that lai granger causes llcf and reject the null hypothesis. additionally, there prevails a bidirectional causal relationship (p-values of 0.0064 and 0.0195, respectively) between lfd and lcf, demonstrating that changes in one factor also affect the other. furthermore, as the p-values for ldge and lcf are below the traditional level, suggesting that both variables granger cause one another, there is a bidirectional causal connection between them. furthermore, with p-values of 0.0268 and 0.0066, lurba granger causes llcf and vice versa. because the p-values are below the conventional level, we could dismiss the null hypothesis. in contrast, there exists no significant causal connection as displayed through p-values greater than the normal significance threshold for the relationships between llcf and lgdp, llcf and lgdp2, and llcf and lai. thus, in these instances, we cannot rule out the null hypothesis that there is no existence of causality. global sustainability research global scientific research 42 table 8. d-h causality test null hypothesis

concerning artificial intelligence (ai), economic growth, financial innovation, the digital economy, and urbanization. the analysis uses sophisticated econometric techniques to validate the load capacity curve (lcc) hypothesis, and the results provide important insights into the complicated connections between financial activities and the well-being of the natural world. the findings of the stationarity analyses demonstrate that there are no unit root difficulties and that the parameters exhibit varying degrees of integration. the lcc hypothesis is confirmed in both the short and long term in the group-7 region by the mmqr calculations, revealing a beneficial relationship between long-term economic growth, ai, financial development, and lcf. on the contrary, urbanization, the digital economy, and gdp growth in the near future are detrimental to lcf. it is anticipated that financial growth will supply the capital required to invest in sustainable innovations that will boost industrial operations. similarly, strong advancements in ai coupled with green growth stimulate the establishment of fresh ideas and the implementation of sustainable habits by promoting competitiveness and granting access to the latest technologies. the dkse, amg, and ccemg tests, which corroborate the outcomes of the mmqr, add to the results' robustness. furthermore, significant one-way causal linkages between lgdp, lgdp2, lai, lfd, ldge, lurba, and llcf were found by the d-h causality analyses. these links highlight how the g-7 region's environmental sustainability dynamics are influenced by shifts in economic activity, advances in artificial intelligence, digital technology, urbanization, and financial expansion. as a result, the analysis provides several policy recommendations that, when paired with green development, improvements in technology, and practical urban infrastructure, ought to support a healthy environment in the selected region. in order to tackle the u-shaped correlation between income and load capacity factor in the g-7 region, strategies must be developed to ensure both environmental sustainability and gdp expansion. as affluence increases, it is important to enforce more stringent rules on pollution and resource utilization in order to reduce the destructive effects on environmental sustainability. providing subsidies and tax incentives to promote green technology and sustainable practices can effectively reduce environmental deterioration in the early phases of economic global sustainability research global scientific research 43 development. moreover, allocating resources towards education and awareness initiatives might foster sustainable customer behavior. with the ongoing increase in wealth, it is imperative to redirect policy toward the promotion of sophisticated, clean technology and renewable energy sources. this will guarantee that rising income levels result in enhanced environmental consequences. promoting corporate accountability and incorporating sustainability indicators into financial reporting may effectively propel organizations toward adopting more environmentally friendly practices. collaborating and exchanging ideas between g-7 countries can further improve the efficacy of these initiatives. to promote environmental sustainability in the group seven territories, policies should prioritize the integration of financial development and ai innovation into environmental strategies. governments should prioritize the provision of financing and support for ai-driven technologies that facilitate the transition to renewable energy, optimize resource utilization, and improve environmental monitoring. innovation and adoption can be stimulated by incentives for private sector investments in ecological ai solutions. concurrently, financial policies should promote sustainable investment portfolios and green bonds, guaranteeing that financial development is consistent with sustainability objectives. transparency and effectiveness will be guaranteed by the establishment of distinct standards and metrics for assessing the environmental impact of financial investments and ai. fostering collaboration among environmental organizations, financial institutions, and tech developers, as well as promoting public-private partnerships, can facilitate the integration of ai-driven sustainability initiatives. furthermore, policies should promote the creation of financial instruments that facilitate projects that generate substantial environmental benefits, thereby ensuring that financial growth is consistent with sustainable outcomes. the potential of ai and financial development can be leveraged by the g-7 countries to improve the green ecosystem through the implementation of these measures. policies should concentrate on sustainable development techniques in order to mitigate the negative consequences of the urban population and the rise of the digital economy on the lcf in the g-7 area. encourage the it industry to adopt energy-efficient practices and technology in order to lessen its environmental impact on the digital economy. incorporate green data center guidelines and incentives and encourage the use of clean power sources in digital infrastructure. to mitigate the ecological impact of urbanization, give priority to smart city design that includes green infrastructure and effective land use. regulations should be strengthened to guarantee that stringent environmental impact assessments and sustainability initiatives coincide with urban growth. invest in green building techniques and public transportation to lessen the total demand for natural resources. enforce stricter zoning regulations to safeguard natural regions and encourage mixed-use constructions that lessen the need for sprawling metropolitan areas. through the integration of these measures, the g-7 nations may alleviate the detrimental impacts of urbanization and the rise of the digital economy on environmental sustainability, guaranteeing that technological and economic progress does not come at the price of ecological well-being. declaration acknowledgment: n/a

cassava; food security; cameroon introduction agricultural commodities, especially food, are essential to meet national food needs and rural livelihoods (oecdfao, 2024; lestari et al., 2022). the availability of these commodities is necessary to ensure the daily food consumption of society and to ensure a consistent food supply (shen et al., 2024). however, agricultural commodities often experience price fluctuations in their development agricultural commodities often experience price fluctuations in their development (antwi et al., 2021;

onumah et al., 2022; hamilton et al., 2020; hlpe, 2011; olila et al., 2016; onyuma et al., 2006; sousa, 2017). previous studies (temple, 2006; nzossie, 2013; kane et al., 2015) reported alarming increases and volatility in staple food prices in cameroon, coupled with inadequate market price transmission, that plunged millions of global sustainability research global scientific research 37 people into food insecurity, worsening the living conditions of many people (akpan and udoh, 2009).food price volatility poses a significant threat to agriculture, especially in developing countries (subervie, 2007; oecd, 2011). this volatility can stem from various factors such as inadequate transport infrastructure, communication services, government intervention mechanisms, the complexity of marketing channels, and contractual agreements among economic actors (meyer and von cramon-taubadel, 2004). these imperfections are exacerbated by irregularities in the number and transparency of market participants, which alter market structures and subsequently affect price determination. agricultural markets often deviate from the conditions of pure and perfect competition (guerrien, 2006), leading to non-reciprocal relationships in commodity price movements across different stages of the marketing chain.understanding the level of market integration within cameroon, shaped by its unique geographical characteristics, is crucial. equally important is discerning the factors that influence why some regions exhibit high spatial integration while others show weak or no integration at all (gonzalo et al., 2012). furthermore, weak integration implies limited domestic supply responses to increasing commodity prices. a nonintegrated market operates blindly, with producers unable to discern highly valued global market trends, potentially leading to suboptimal decision-making and inefficiencies (gonzalo et al., 2012). vavra and goodwin (2005) observed that the speed of market adjustments to shocks hinges on the actions of market agents—such as wholesalers, distributors, processors, and retailers—who facilitate transactions across market levels. in an unintegrated market, incomplete price information may distort production decisions. market price instability can profoundly impact food security, particularly affecting the access of poor households to food in the short term and influencing producers' incentives to invest and enhance production in the long term (galtier, 2009).in cameroon in particular, fluctuations in these prices, which exacerbate situations of food insecurity for the poorest households, have raised debate about the role of agriculture in this country, food security, and even food selfsufficiency insofar as the country is heavily dependent on food imports (minkoua, 2018; kane, 2018). the formulation of policies to stabilise food markets is a key issue for long-term agricultural development through the control of price movements, which are recognised in the literature as affecting farmers' technological investments. implementing these policies requires prior identification of the various factors that influence food prices. food price volatility is a major agricultural phenomenon, particularly in developing countries, given that agriculture is the main source of income for populations (prakassh, 2011). agricultural price volatility is a phenomenon that has often occurred in the past but has never reached current figures (lanfranchi et al., 2019). today, this condition has become a structural feature of global agricultural markets. according to ceballos et al. (2017), the problem of agricultural price instability can be attributed to one main factor linked to the evolving dynamics of world markets. this price phenomenon has received considerable attention in the economic literature (e.g., lloyd, 2017; assefa et al., 2015; frey & manera, 2007; meyer & cramon-taubadel, 2004), which examines the links between prices at all stages of the agricultural market. agricultural price volatility is a phenomenon that has often occurred in the past but has never reached current figures (lanfranchi et al., 2019; pan& zheng, 2023). today, this condition has become a structural feature of global agricultural markets. according to ceballos et al. (2017), the problem of agricultural price instability can be attributed to one main factor linked to the evolving dynamics of world markets. this price phenomenon has received considerable attention in the economic literature (e.g., lloyd, 2017; assefa et al., 2015; frey & manera, 2007; meyer & cramon-taubadel, 2004), which examines the links between prices at all stages of the agricultural market. this study also contributes to the existing literature on the transmission of agricultural commodity price volatility in developing countries. in particular, volatility transmission models may vary from one country to another due to differences in institutional and economic development. while much of the current literature has focused on global sustainability research global scientific research 38 developed countries capable of large-scale production through advanced technologies and efficient business operations, such as germany (assefa et al., 2017) and the united states (buguk et al., 2003), few studies have focused on developing countries with the characteristics of a decentralised, smallholder economy. our results provide new cameroonian evidence for this strand of the empirical literature. furthermore, we contribute to the literature on the dynamics of price volatility in agricultural commodity markets in cameroon (e.g njoda & nkot, 2017; minkoua et al, 2018; kane et al, 2019;). literature review conceptual framework the schema depicts that whether or not markets are integrated depends on several factors. these factors are at the heart of the search for better prescription in order to improve the efficiency of the markets. figure 1: conceptual framework source: author’s conceptualization, 2022. the heed to these strategies depends on a number of factors affect the market integration system. these include institutional, environmental and socio-economic factors (figure 1). institutional factors include government policies, lack of information, lack of basic infrastructure such as all-weather roads, storage facilities, transport, lack of credit, etc. most assessments of constraints for farmers indicate that the lack of rural transport is a major obstacle for farmers seeking to market their surplus crops. limited local transport means not only increased costs but also that traders are less willing to travel, market information is more limited and farmers' choice of marketing institutional factors ➢ government policies ➢ transaction cost ➢ infrastructure ➢ lack of information ➢ lack of credit socio-economic factors ➢ population growth ➢ income ➢ supply ➢ technology environmental factors ➢ climate change ➢ saisonality ➢ agricultural production price volatility ➢ functioning markets ➢ availability of food ➢ price stability ➢ supply undisrupted global sustainability research global scientific research 39 channels is very limited, which greatly reduces their ability to sell their produce, which greatly reduces their bargaining power. while socio-economic factors include: population growth, income, supply and technology. finally, environmental factors include: climate change, seasonality, and agricultural production. therefore, when two markets are integrated due to functioning markets, availability of food, price stability, supply undisrupted, it means that government policies need to be set up to improve transport and communication infrastructure, and cassava price information needs to be adequate for market participants, which leads to decisions that contribute to efficient outcomes or efficient markets. improving transaction costs can increase the participation of market agents and improve the flow of cassava from surplus to deficit areas. to achieve this objective, the government may resort to price controls, which can be seen as a price guarantee policy. in one case, the government may set an artificially high price (floor price) to ensure a higher income for producers than in the case of a free market. in another case, the government may impose artificially low prices (price ceiling) to ensure that consumers receive a lower income than in the case of a free market and thus increase their purchasing power. the alternative to price control policies is the "price band" (holt and aradhyula, 1990). in the latter case, the government only intervenes if prices fluctuate outside a defined price band. thus, to stabilise prices when they fluctuate outside the band, the government can use, among other things: imports, exports and stock changes (de janvry et al., 1995). indeed, such measures do not allow prices to fully play their role as a 'signal' to actors; a signal that allows economic agents to efficiently use their scarce resources (petkantchin, 2006). thus, instead of stabilising prices in agricultural markets, these measures can act as distortions of the market and make it more volatile, mainly due to overproduction in one case, and in the other, it can discourage investment, innovation and production. on the other hand, other economic policy measures, such as taxes and subsidies, market-oriented government programmes, and loan ratios have been mentioned as determining food price volatility. methodology source of data cameroon is located between latitude 2° n to 13° n: longitude 8° 25° e and 16° 20° e in the central african sub region. it opens to the atlantic ocean in the west with a total coastline of 402 km. it is bounded to the west by nigeria, north-east by chad, south by gabon, dr congo, and equatorial guinea and to the east by central african republic. it has a total surface area of 475 650 km 475,650 km which is distributed into five agroecological zones in ten geographical regions (minfof, 2018) (minfof, 2018). it is composed of 10 regions with five major agroecological zones most notably the sudano-sahelian, high guinea savannah, western highland, monomodal humid rainforest, and the bimodal rainforest (fig. 1). this agroecological diversity permits the conditions necessary for the growth of most crops which characterize other african nations hence the name "africa in miniature" (minepded, 2017). this by this natural virtue over other african nations, makes cameroon has become the breadbasket of central africa and supplies gabon, central african republic, equatorial guinea, and tchad as well as neighboring nigeria to the west. our study is conducted in the west, northwest (western highlands), and the littoral and south-west (monomodal humid rainforest), the centre, east and south (bimodal humid rainforest) regions of cameroon (minader, 2010; minresi, 2007). this three agroecology are chosen because they have a characteristic tropical climate of two seasons (a rainy season and a dry season) which permits the cultivation of cassava (molua and lambi, 2015). apart from the favorable climate for cassava production, these areas also harbor the largest markets for retail and wholesale of cassava produced (yaoundé, douala and bafoussam) and its derivatives. global sustainability research global scientific research 40 furthermore, the “main” markets of these areas are interconnected by accessible roads. thus, making it ideal for our analysis. figure 2: map of cameroon showing selected study area and location of markets source: (constructed from atlas-forest dataset cameroon, 2023) it covered traders who sells and buy cassava in the study area. secondary data used in this study was obtained from the national institute of statistics (nis) are used to analyze the determinants of food price volatility in cameroon. we consider the period from january 1994 to december 2022 and was divided into three strata (regions). secondary data from the national institute of statistics (nis) were used to examine the possible threshold effects on price transmission two threshold co-integration models, namely the threshold autoregressive (tar) model and the momentum-threshold autoregressive (m-tar) model are used. (enders and siklos,2001) established these threshold co-integration tests where negative and positive deviations from the long-run equilibrium are not adjusted in the same way, that is, there is asymmetry in long-run adjustment to the equilibrium (ndoricimpa and achandi, 2014). the lag of the variables is used in tar model, whereas previous period’s changes are preferred in m-tar model as a threshold variable. to model the possibility that the short-run dynamic relationship acts in diverse ways depending on the magnitude of deviation from the equilibrium, threshold co-integration is used. the tar model captures asymmetrically “deep” movements in the series, while the m-tar model captures asymmetrically sharp or “steep” movements. global sustainability research global scientific research 41 (enders and siklos, 2001) proposed the following steps to test for threshold co-integration using tar and mtar models. in the first step, the following long-run equilibrium relationship is estimated: p1 t = β0 +βp2 t +µt (1) where, p1 t and p2 t are the price of rice in two markets within a pair, say, farm and wholesale price or retail and wholesale price, respectively. µ is the disturbance term. then the following equation is estimated using ordinary least squares (ols): ∆µt = itρ1µt−1 +(1 − it)ρ2µt−1 +σik=1 β∆µt−i +εt (2) where, µt is the residual series from equation (7), k is the lag length and it is the heaviside indicator function such that: ( 1 if µ t−1 ≥λ it = for tar model (8) 0 if µt−1 <λ and it for m-tar model (3) the lagged dependent variable values are added in order to ensure that the residuals are white noise. the lag lengths are selected using aic and sbic. finally, tar and m-tar co-integration and adjustment process are specified as: ( ρ µ− +ε if µ− ≥λ) the number of lags k to include in the tar and mtar models were also selected by using tar and m-tar models. the optimal threshold value λ minimizing the residuals sums of squares was estimated using (chan’s, 1993) method. given the alternative models, model selection procedures such as the aic and sbic provides a basis for choosing between tar and m-tar. a model with the lowest aic and sbic should be preferred (acquah, 2012). results and discussions findings show that prices are very unstable (coefficient of variation greater than 15%) within the study period. the fluctuations calculated from the coefficient of variation show that the price of cassava varies by 51.5% above or below its average value in the west region. ∆µt = 1 t 1 t t 1 ρ2µt−1 +εt if µt−1 <λ for tar model and; (4) global sustainability research global scientific research 42 figure 3: evolution of cassava prices on the west, centre and littoral markets source: nsi/ author (2022) figure 3 below shows that, in general, cassava prices on the studied markets are on an upward trend, with the price of cassava on the littoral remaining the highest at an average of 130.5 cfaf/kg, while the lowest price is observed on the west market with an average price of 64.9 cfaf/kg. a comparison of prices on the three markets from january 2000 to december 2012 shows that the price on the western market is characterized by little fluctuation, while the prices of manioc on the central and coastal markets are characterized by strong fluctuations. this irregularity could be explained by seasonality. from january 2012 to december 2022, a comparison of prices on the three markets shows that the price of cassava in the littoral and centre markets remains relatively constant, while the price in the west region market is characterized by strong fluctuations. the implication is that the west region remains the area where the supply of cassava is cheapest; table 1: coefficients of variation for cassava

market, it fluctuates around its average value by almost 16.9%. the price of cassava is therefore less volatile in the littoral region than in the other two regions. table 2: matrix of price

findings show that the price series in the centre region is strongly (r = 0.88) positively correlated with the price of the littoral. in general, this shows that prices are relatively correlated in the study period. study of the seasonality of variables the kruskal-wallis test, applied to the three nominal price series, gave the following results: kw= 25.03 (pvalue= 0.9%) for the cassava price series in the centre and a kw= 9.28 (p-value= 59.6%) statistic in the littoral and finally a dw = 38.12 (p-value =0.007%) statistic for the west series. thus, at the 10% threshold, the price of cassava in the littoral shows no seasonality, whereas the price of cassava in the centre and west are seasonal. however, the cassava price series in the centre and west regions have been corrected for seasonal variations. study of the stationarity of variables in order to study cointegration, a necessary condition is that the variables must be integrated of the same order. this is why we devote this section to the study of the stationarity of the variables. in this work, the philips-perron (pp) augmented dickey and fuller (adf) unit root test and the kwiatkowski-phillips-schmidt shin (kpss) stationarity test without trend or constant are performed on all the variables in the study. table 3: unit root test on the different variables level tests first difference variables adf pp kpss adf

possible long-term relationship between prices in the different regions. the results of these tests are reported in table 3. the study of the stationarity of the variables shows that all the variables are stationary in first difference. indeed, the two tests (adf, pp, kpss) lead to the conclusion that the price of cassava in the littoral, centre and west regions admit a unit root in level but are all stationary in first difference. thus, they are all integrated of order 1 at the 5% threshold. in conclusion, the variables are considered to be integrated of order 1. pairwise cointegration

that the residual series of the long-term model is stationary. these two steps finally indicate that cassava prices are linearly cointegrated such that there is a restoring force tending to bring the centre cassava price back to the long-term equilibrium in response to variations in the littoral cassava price. there is therefore a linear long-term relationship between the different cassava price series. in particular, the price of cassava in the littoral is explained by the price of cassava in the west region in the long term. once the long-term relationship has been estimated, stationarity tests have been carried out on the residual. in this case the dickey and fuller (1979) table is no longer valid, the mackinnon (1993) table is used. the results show that the residuals are stationary, so the variables are cointegrated. the threshold cointegration test the estimation of a tar model, from the residual from the above long-run relationship, yielded the following results: tar model of

analysis shows that the changes made on the littoral markets are fully transmitted to the centre market. indeed, the elasticity of the centre price with respect to the littoral price is greater than 1 for all relationships. a 1% increase in littoral prices in the long run leads to a 114% increase in the price of cassava in the centre. elasticities greater than 1 indicate that littoral prices are not fully transmitted to centre prices. once the long-term relationship was estimated, stationarity tests were carried out on the residual. global sustainability research global scientific research 46

and the conclusion of seasonality tests are presented in table 6. we used two tests: the f-test and the q2 parameter test. we use seasonally adjusted data for econometric models when the two tests have suggested the existence of seasonality. however, when the results have pointed out the evidence of a non-stable seasonality global sustainability research global scientific research 47 and lead to contradictory conclusions (when the f test suggest the presence of seasonality, but the q2 parameter suggest the rejection of the hypothesis of seasonality), i use non-seasonally adjusted data. determinants of price volatility from what appears in table 7, we can see that the model is globally significant for modelling price volatility. the variables that explain this volatility are yield, inflation, interest, temperature and climate. the determinants of price volatility of cassava are presented in table 48 below. all the variables are significant and affect market efficiency in one way or the other, either positively or negatively. to begin with, • yield the coefficient on the yield variable is positive and significant at the 5% level. this result indicates that a seller's returns increase the probability that cassava prices are volatile at the 5% level. marginal effects inform us that sellers' returns contribute 25% to the probability that cassava prices are volatile. • interest the coefficient of the variable interest is negative and significant at the 5% level. this result indicates that interest reduces the probability that cassava prices are volatile. the marginal effects inform us that interest contributes negatively to 57% of the probability of price volatility. • climate the coefficient on the climate variable is positive and significant at the 5% level. this result indicates that climate change increases the probability that cassava prices will be volatile. the marginal effects inform us that the stock variation contributes to 17% of the probability of cassava price volatility. table 7: drivers of price volatility variables coefficients p value dy/dx yield 0.25** 0.009 0.25 inflation -0.076 0.259 -0.076 interest 0.082** 0.000 0.055

root tests without and with structural break (adf and pp) suggest that all the return price series are stationary (see table 1.8 in the appendix). in addition, the box and jenkins approach has been used to determine the appropriate arma structure of each return price series. also, for each arma model, a breusch-godfrey serial correlation lm test has been applied and an arch lm test has been used

homoscedastic (p=0.0000). resid(-1)^2 + garch = 0.747 approximately 0.75 which is closer to 1, implying that the persistence of volatility is high. the garch(1,1) model as modelled is significant overall. there is therefore conditional heteroscedasticity in the error term. the chi2 distribution and the critical probability associated with this distribution of the garch(1,1) regression show that the model as specified is globally significant at the 5% threshold for the price of cassava as indicated in table 14 above. both ar(2) and ma(2) coefficients which represent the mean equation are significant only in arch(1 2) i.e resid(-1)^2 and resid(-2)^2 coefficients which represent the variance equation are significant as well. resid(-1)^2 + resid(-2)^2 = 0.2 which is not closer to 1, implying that the persistence of volatility is very low. resid(-1)^2 + garch = 0.2, is very close to one, and this shows that the average price of the selected major food items will continue to be high will continue to be volatile. the result shows that cassava price is volatile. the summation of the coefficients of the arch (0.150000) and garch (0.050000) is very close to one, and this shows that price of cassava continue to be volatile and it is in line with a priori expectation. observations show that inflations in cameroon fluctuate and affect household spending patterns. f test shows no heteroscedasticity implying no arch effect again. hence model is robust. the table above presents the results of the heteroscedasticity test of the residuals. the analysis of this table shows that the residuals are homoscedastic (p=0.0000). discussion the results of the augmented dickey-fuller test for cassava prices are individually significant at the 5% level. the model estimation process consisted of two steps: a stationary test and the determination of the arch model. stationary tests were used to assess trends (erkekoglu, garang and deng, 2020; şahinli, 2020). data can be stationary if the process does not change over time. the augmented dickey-fuller (adf) test was used to perform the stationary test. the adf test was used to determine whether the data analysed contained a unit root. if the pvalue was > 0.05, then h0 was accepted and the cassava price data were not stationary. however, if the p-value was < 0.05, h0 was rejected and the cassava price data were stationary. the result of the arch/garch analysis indicated that the persistence of volatility is greater in cassava prices. he model used to detect heteroskedasticity can be determined by examining the significance of the probability values of the f-stat and chi-squared at the 5% significance level (das, paul, bhar and paul, 2020; deb, 2021; lakshmanasamy, 2021; lestar et al., 2022). the arch/garch result also implies that higher cassava price volatility could adversely affect households by causing hunger or severe food insecurity, leading to malnutrition and riots. specifically, in the west region, the conditional variance coefficient is positive and individually significant at 5%. this indicates that the f-test does not show heteroskedasticity, which means that there is no arch effect. this is indicated by the f-statistic and chi-square probability values of 0.0000 < 0.05. the model is therefore analysed in more detail using arch-garch analysis (jordaan et al., 2007; manogna & mishra, 2020). the results show the heteroscedasticity test for the residuals; the sum of the arch and garch effects (0.997) indicates that cassava prices are highly volatile; in the littoral region, the f-test shows no heteroscedasticity, which means that there is no arch effect. the model is therefore robust. there are no more lags in the autocorrelation and partial correlation functions, and the probability values are greater than 0.05. the garch (1 1) model therefore satisfies the model specification. the value of the arch coefficient illustrates the high volatility of manioc prices. the closer the value of the arch coefficient (1.0) is to zero, the lower the volatility (monk et al., 2010; thiyagarajan et al., 2015). the estimated model yielded an arch coefficient of 0.277477, implying that the volatility of cassava in the coastal region from global sustainability research global scientific research 54 1994 to 2004 is relatively low and close to zero. volatility is a measure of price fluctuations or expected price movements over time (barbaglia, croux and wilms, 2020; onour and sergi, 2011; manogna and mishra, 2020; thiyagarajan et al., 2015; lestar et al., 2022). volatility also refers to unexpected price fluctuations, but this has yet to be determined. some measures of volatility and risk assessment can be based on deviation, standard deviation and coefficient of variation. in the centre region, the conditional variance coefficient is positive and individually significant at 5%. this indicates that there is no arch effect, as the residual term and the f-test are not significant. the constant term is insignificant. the coefficient on the first lagged value of the price of cassava is significant at 5%. thus, the price of cassava today is determined by the price of cassava in the immediate past. the significance of the arch and garch terms indicates that the volatility of prices in a given month depends on the volatility of prices in the previous month and that the variance of the current price depends on the variances of past prices. the coefficients imply that when price peaks occur, the process is very slow to reverse. the volatility of cassava prices can be measured using the conditional deviation norm, which was the root of arch-garch (1.0). the price of cassava in the centre region was not very volatile between 2012 and 2020. however, in certain months of 2008 and 2012, relatively large fluctuations occurred several times in january, june and october. the high volatility of cassava prices between 2008 and 2014 was due to the rise in commodity prices and the global financial crisis, which generally made sellers reluctant to unload their produce due to the risk of damage and high loss rates. the findings of the model show that inflation and climate have positive and significant effects on the price of cassava. this means that a percentage change in inflation is expected to increase the price of cassava by 0.79 % and 1% increase in the exchange rate is expected to increase cassava price by 1.02%. this calls for effective management of these macroeconomic variables to provide continuous stable environment against price fluctuation. moreover, variables such as yield and temperature have positive relationship with the price of cassava while interest rate and rainfall have negative relationship with cassava price though they are not significant. the result is consistent with an empirical work by gilbert (1989) which indicated that inflation level and its variability are major factors that influence food price volatility and can greatly affect the investors including farmers. this assertion was also stated by imf (2008) which also showed that fluctuations in inflation and exchange rate are condiments for output price volatility. the positive relationship between the price of cassava and the quantity supplied (cassava yield) is consisted with the economic theory which states a positive relationship between the price of a commodity and its supply. this may explain why high prices persisted in cameroon even after the 2008/9 food price crisis. indeed, the volatility of cassava prices is a problem in cameroon and several other countries (devi, srikala, & ananda, 2015; kane et al., 2018). the high volatility of cassava prices requires government intervention to stabilise them (kane et al, 2018). this can serve as a reference for the government to develop policies to stabilise cassava prices. conclusion the results highlight the following main points concerning price fluctuations for the cassava studied. firstly, they confirm that cassava prices are more unstable than those of their presumed imported substitutes, which are storable and/or processed products. secondly, a multiplicity of factors determines price fluctuations, such as inflation, interest, temperature and climate. flows between regions, and probably the associated cropping systems that predominate in agroforestry, help to mitigate the impact of climatic hazards on consumer prices. furthermore, the aim of reducing the uncertainties of domestic food markets could lead to renewed investment in local food chains, whose competitiveness would contribute to development mechanisms (poverty reduction, job creation, etc.). by these studies finding, the following recommendations were made: global sustainability research global scientific research 55 1. marketers should organize themselves into cooperatives to enable them reap the benefits of economy of scale in areas of product transportation and storage. this would also help them benefit from credit facilities from agricultural and commercial banks and other micro credit financial institutions; 2. means of transport should also be put in place thanks to the efforts of cooperatives to link farms to the market in order to reduce marketing costs and increase profits for traders. 3. there should also be the erection of market stalls, stores, and reduction in market taxes so as to improve the marketing of cassava in the study area. declaration acknowledgment: i would like to express my deepest

sustainable agriculture; nigeria; precision farming; food security; agricultural transformation introduction agriculture is a cornerstone of nigeria's economy, employing over 70% of the workforce and contributing approximately 22% to the nation’s gross domestic product (gdp) (food and agriculture organization [fao], 2020). the sector is characterized by smallholder farming, with many farmers relying on traditional practices that often result in low productivity and inefficient resource use. despite nigeria’s vast agricultural potential, challenges such as land degradation, inadequate infrastructure, and fluctuating climatic conditions have hindered global sustainability research global scientific research 96 significant growth (ibitoye et al., 2021). additionally, food insecurity remains a critical issue, with about 25% of the population facing severe food shortages (world food programme [wfp], 2022). given these challenges, it is imperative to explore innovative solutions that can enhance agricultural practices and ensure food security while promoting environmental sustainability. sustainable agricultural transformation is essential for addressing food security, enhancing productivity, and mitigating the adverse effects of climate change (united nations [un], 2019). this transformation involves adopting practices that increase agricultural output while preserving natural resources and ensuring the welfare of farming communities. in nigeria, sustainable agricultural practices can lead to improved soil health, better water management, and increased resilience to climate variability (ojo et al., 2021). furthermore, sustainable agriculture can also contribute to economic growth by providing job opportunities, enhancing rural livelihoods, and reducing poverty (adesina et al., 2020). therefore, the integration of innovative technologies, such as artificial intelligence (ai), is crucial for achieving these sustainability goals in the agricultural sector. artificial intelligence technologies have emerged as powerful tools capable of revolutionizing modern farming practices. ai applications in agriculture include precision farming, autonomous machinery, crop monitoring systems, and predictive analytics for yield forecasting (wolfert et al., 2017). for instance, precision agriculture leverages ai to analyze data collected from various sources, enabling farmers to make informed decisions regarding resource allocation, pest management, and crop health monitoring (kamilaris & prenafeta-boldú, 2018). moreover, ai-driven systems can enhance the efficiency of agricultural operations by automating labor-intensive tasks and improving overall productivity ((zhang, 2022;sullivan et al., 2020). as such, the adoption of ai technologies in nigerian agriculture could significantly contribute to sustainable agricultural transformation by optimizing resource use and increasing crop yields. this study aims to explore the role of ai in modern farming practices and its potential to facilitate sustainable agricultural transformation in nigeria. by conducting a systematic literature review, the research will identify the current state of ai applications in agriculture, the benefits its provide, and the barriers to its adoption. ultimately, the findings will contribute to a deeper understanding of how ai can be leveraged to enhance agricultural sustainability in nigeria, informing policymakers, researchers, and practitioners. moreover, to provide empirical and case studies data, ai adoption across nigerian six geopolitical zones, as well as socio-economic classes, finally, the technology readiness for ai adoption in agriculture. literature review this literature review explores the role of artificial intelligence (ai) in modern farming, particularly in the context of sustainable agricultural transformation in nigeria. it covers the historical context of agricultural practices, emerging ai technologies, global perspectives on ai in sustainable farming, and the current state of research in nigeria. historical context of agricultural practices in nigeria agriculture has been a cornerstone of nigeria's economy, historically characterized by subsistence farming practices. traditional agricultural methods relied heavily on manual labor, indigenous knowledge, and local environmental conditions, which often resulted in low productivity. according to ogunniyi (2021), the reliance on traditional practices has made farmers vulnerable to environmental changes such as climate variability, pest infestations, and soil degradation. over the years, nigeria's agricultural sector has faced numerous challenges, including inadequate infrastructure, limited access to markets, and insufficient technology adoption (giua et al., 2020; ojo et al., 2020). the introduction of modern agricultural techniques and technologies has been slow, but global sustainability research global scientific research 97 recent trends indicate a shift towards more sustainable practices. the nigerian government has recognized the need for agricultural transformation, aiming to enhance productivity and resilience against climate change through policies that promote technology adoption (nigerian federal ministry of agriculture & rural development, 2022). emerging ai technologies in agriculture emerging ai technologies are revolutionizing agricultural practices by providing tools for real-time monitoring, predictive analytics, and automated decision-making. technologies such as machine learning, computer vision, and drones are increasingly being utilized to optimize farming operations. for instance, ai algorithms can analyze data from soil sensors, weather forecasts, and satellite imagery to determine optimal planting schedules and manage irrigation efficiently (kumar et al., 2022). a study by adebayo et al. (2023) shows that ai-driven precision agriculture can significantly enhance crop yields while reducing resource wastage. the integration of ai in agriculture not only improves productivity but also promotes sustainable practices by minimizing the environmental impact of farming. for example, ai systems can predict pest outbreaks, allowing for timely interventions that reduce the need for harmful pesticides (singh et al., 2021). global perspectives on ai in sustainable farming globally, ai is recognized as a transformative force in achieving sustainable agricultural practices. countries are increasingly adopting ai-driven solutions to address food security challenges posed by a growing population and climate change. the concept of "smart farming," which incorporates ai, iot, and robotics, is gaining traction as a means to secure food production while ensuring environmental sustainability (wolfert et al., 2017). for instance, in developed countries like the united states and canada, ai technologies are being employed in precision agriculture to enhance resource allocation and improve crop management (zhang et al., 2019). these ai applications contribute to broader sustainability goals, such as reducing greenhouse gas emissions and conserving biodiversity. such global perspectives underscore the potential of ai not only to increase agricultural productivity but also to contribute to the sustainability of food systems worldwide. current state of research in nigeria research on ai in agriculture within nigeria is still in its nascent stages, but it is rapidly gaining momentum. recent studies have highlighted the potential benefits of ai technologies in addressing the challenges faced by nigerian farmers, such as low productivity and knowledge gaps (abdul et al., 2023). initiatives aimed at educating farmers about ai applications and providing access to these technologies are crucial for enhancing agricultural outputs. furthermore, ongoing research focuses on developing ai solutions tailored to the unique agricultural conditions in nigeria. for instance, projects aimed at creating localized ai models for predicting crop yields and disease outbreaks are being explored (ibrahim et al., 2023). as the agricultural landscape evolves, the integration of ai is expected to play a pivotal role in transforming nigeria's agricultural sector into a more sustainable and productive system. methodology a semi-systematic literature review is a research methodology that combines elements of both systematic and traditional literature reviews. it is designed to provide a comprehensive overview of existing literature while allowing for some flexibility in the selection and evaluation of sources. the primary purpose of a semi-slr is to synthesize findings from various studies to identify trends, gaps, and insights related to a specific research question global sustainability research global scientific research 98 (munn et al., 2018). unlike a fully systematic review, which follows strict protocols for study selection and data extraction, a semi-slr allows researchers to be more exploratory, accommodating diverse types of literature, including empirical studies, theoretical papers, and grey literature (peters et al., 2015). this approach is particularly beneficial in rapidly evolving fields such as artificial intelligence in agriculture, where new findings and technologies frequently emerge. search strategies the search strategy for this semi-slr involved a comprehensive and iterative process using multiple academic databases, including scopus, web of science, and google scholar. keywords and phrases relevant to the research topic, such as (artificial intelligence in agriculture, or (ai applications in agriculture, and (sustainable farming in nigeria,))) were utilized to maximize the breadth of literature retrieved (higgins & green, 2011). boolean operators (and, or) were employed to refine searches, allowing for a combination of terms that targeted specific aspects of ai and sustainable agriculture. additionally, the search included recent publications from the last ten years to ensure the review reflected the most current advancements and challenges in the field (khalil et al., 2020). figure 1. reputable academic databases inclusion and exclusion criteria to ensure the relevance and quality of the literature reviewed, specific inclusion and exclusion criteria were established. studies excluded or included in the review were required to meet the following criteria as shown in table 1. table 1. inclusion and exclusion criteria inclusion criteria exclusion criteria it must focus on the application of ai technologies in agriculture specifically within the context of nigeria or similar developing countries. studies were excluded if it did not pertain to ai, were not related to agriculture, or were published before 2015. it must be peer-reviewed articles, conference papers, or credible grey literature published within the last decade literature that lacked rigor or was not peerreviewed was also excluded to maintain the integrity of the review it must provide empirical data or substantial theoretical insights relevant to sustainable agricultural transformation literature that failed to provide empirical data or substantial theoretical insights relevant to sustainable agricultural transformation 6 6 8 0 1 2 3 4 5 6 7 8 9 scopus web of sciences google scholar global sustainability research global scientific research 99 data extraction and synthesis techniques data extraction involved systematically cataloging information from the selected studies, including authorship, publication year, study design, key findings, and relevant methodologies. a standardized extraction form was developed to facilitate consistency and accuracy (higgins & green, 2011). following extraction, the synthesized data were analyzed qualitatively, employing thematic analysis to identify common themes, trends, and challenges associated with the adoption of ai in nigerian agriculture. the synthesis process also involved a narrative approach to contextualize findings within the broader landscape of sustainable agricultural practices, drawing connections between the literature and the overarching research aim (thomas & harden, 2008). this combination of qualitative and quantitative synthesis allowed for a comprehensive understanding of the role ai plays in transforming agriculture in nigeria. results and discussion overview of ai applications in modern farming the integration of artificial intelligence (ai) in modern farming practices has revolutionized agricultural operations, enhancing efficiency and sustainability. this section discusses key ai applications that are transforming agriculture, particularly in the context of nigeria. resource optimization (water, fertilizer, etc.) ai applications also play a vital role in optimizing resource use in agriculture, particularly concerning water and fertilizer management and it constitutes 40% of 20 literature reviewed in this study (see figure 2). smart irrigation systems powered by ai can analyze weather forecasts, soil moisture levels, and crop water requirements to deliver precise amounts of water, thereby conserving this critical resource (khan et al., 2020). similarly, ai algorithms can optimize fertilizer application by determining the right type and amount needed for specific crops, reducing waste and environmental impact (zhang et al., 2020). in nigeria, where water scarcity and soil degradation are pressing issues, the adoption of ai-driven resource optimization techniques can lead to more sustainable agricultural practices and improved resilience to climate change. crop monitoring and management ai-driven crop monitoring systems utilize remote sensing technologies and data analytics to track crop growth and health in real-time (fang & su, 2021). as shown in figure 2, it constitutes 35% of 20 literature used in this study. these systems can detect variations in crop conditions, such as nutrient deficiencies or water stress, allowing farmers to respond promptly (zhang et al., 2019). for instance, ai algorithms can analyze images captured by drones or satellites to assess crop vigor and identify areas that require attention (shafique et al., 2020). in nigeria, implementing such monitoring systems can significantly enhance crop management practices, leading to improved productivity and reduced losses due to pests or diseases. global sustainability research global scientific research 100 figure 2. key ai application for agricultural transformation in nigeria pest and disease detection figure 2 illustrated 14% of the 20 literature revealed that the early detection of pests and diseases, is crucial for minimizing crop losses and ensuring food security (farina et al., 2023). ai technologies, including computer vision and machine learning, are increasingly being used to identify pest infestations and disease outbreaks (liu et al., 2020). for example, ai models can analyze images of crops to detect symptoms of diseases or the presence of pests, enabling farmers to take timely action (ferentinos, 2018). in nigeria, where smallholder farmers often lack access to extension services, ai-based pest and disease detection tools can empower them to manage their crops more effectively, reducing reliance on chemical pesticides and promoting sustainable practices. precision agriculture precision agriculture which constitutes 11% of 20 literature of ai and agricultural transformation as shown in figure 2, is one of the most significant applications of ai in farming. it involves the use of ai technologies to analyze data collected from various sources, such as satellite imagery, drones, and sensors, to optimize farming practices (wolfert et al., 2017). by employing machine learning algorithms, farmers can gain insights into soil health, crop conditions, and weather patterns, enabling them to make informed decisions regarding planting, irrigation, and harvesting (kamilaris & prenafeta-boldú, 2018). in nigeria, precision agriculture can help smallholder farmers increase their yields while minimizing resource waste, ultimately contributing to sustainable agricultural practices (ojo et al., 2021). in summary, the application of ai in modern farming offers numerous benefits, including enhanced productivity, improved resource management, and increased sustainability. as nigeria seeks to transform its agricultural sector, leveraging these technologies can play a crucial role in addressing the challenges faced by farmers and promoting sustainable agricultural practices. the successful implementation of ai in agriculture will require collaboration among stakeholders, including government agencies, research institutions, and farmers, to ensure that these technologies are accessible and beneficial to all. precision agriculture 11% crop monitoring & management 35% pest & diseases detection 14% resource optimization 40% global sustainability research global scientific research 101 benefits of ai for sustainable agricultural transformation the integration of artificial intelligence (ai) in agriculture offers numerous benefits that contribute to sustainable agricultural transformation. as shown in figure 3, these benefits encompass increased yield and productivity 33%, reduced environmental impact 12%, enhanced food security 30%, and economic advantages for farmers 25% respectively. figure 3. agricultural transformation benefits increased yield and productivity ai technologies significantly enhance agricultural productivity by enabling farmers to make data-driven decisions. precision agriculture, powered by ai, allows for the analysis of large datasets derived from various sources, including soil sensors, satellite imagery, and weather forecasts (wolfert et al., 2017). by optimizing planting schedules, irrigation needs, and nutrient applications, farmers can maximize crop yields while minimizing inputs (kamilaris & prenafeta-boldú, 2018). for instance, studies have shown that the use of ai in crop management can lead to yield increases of up to 20% in certain regions (zhang et al., 2019). in nigeria, where agricultural productivity is critical for economic growth, the adoption of ai can help farmers achieve higher yields, thus improving their overall productivity. reduced environmental impact ai contributes to sustainable agriculture by promoting practices that minimize environmental harm. by optimizing the use of water and fertilizers, ai can significantly reduce runoff and the associated pollution of water bodies (khan et al., 2020). smart irrigation systems, for example, use ai algorithms to determine the precise amount of water needed, thereby conserving water resources and reducing waste (zhang et al., 2020). furthermore, ai-driven pest management solutions enable farmers to apply pesticides more effectively, targeting only the areas affected by pests, which reduces chemical use and minimizes the impact on non-target organisms (liu et al., 2020). these environmentally friendly practices are vital in nigeria, where unsustainable agricultural methods have led to soil degradation and water scarcity. 33% 12% 30% 25% increase yield & productivity reduce environmental impact enhance food security economic benefits for farmers global sustainability research global scientific research 102 enhanced food security the application of ai in agriculture plays a crucial role in enhancing food security by increasing the efficiency and resilience of food production systems. ai technologies can predict crop yields and identify potential risks, enabling farmers to take proactive measures to mitigate losses (zhang et al., 2019). by improving agricultural productivity, ai helps ensure a stable supply of food, which is essential for combating food insecurity, particularly in developing countries like nigeria (fao, 2020). additionally, ai can facilitate better food distribution logistics, ensuring that food reaches areas of high demand, further enhancing food security (sullivan et al., 2020). economic benefits for farmers the economic advantages of ai adoption in agriculture are significant. by increasing crop yields and optimizing resource use, farmers can enjoy higher profit margins and reduced costs (ojo et al., 2021). ai technologies can also minimize labor costs by automating tasks such as planting, monitoring, and harvesting (kamilaris & prenafeta-boldú, 2018). furthermore, access to ai-driven insights allows farmers to make informed decisions that enhance their market competitiveness (zhang et al., 2020). in nigeria, where many smallholder farmers operate on thin margins, the economic benefits of adopting ai technologies can lead to improved livelihoods and greater investment in sustainable practices. in conclusion, the benefits of ai for sustainable agricultural transformation are profound. by increasing yield and productivity, reducing environmental impacts, enhancing food security, and providing economic advantages, ai technologies hold the potential to revolutionize agriculture in nigeria and beyond. the successful implementation of these technologies will require collaboration among various stakeholders, including governments, research institutions, and farmers, to ensure that the potential of ai is fully realized in promoting sustainable agricultural practices. challenges and barriers to ai adoption despite the numerous benefits that artificial intelligence (ai) can bring to agriculture, several challenges and barriers hinder its widespread adoption, particularly in developing countries like nigeria. these challenges include technological literacy and access, infrastructure limitations, policy and regulatory challenges, and socioeconomic factors. technological literacy and access one of the primary barriers to ai adoption in agriculture is the lack of technological literacy among farmers. many smallholder farmers in nigeria have limited exposure to advanced technologies, which can impede their ability to effectively utilize ai tools (ojo et al., 2021). this gap in knowledge often leads to resistance to adopting new technologies, as farmers may feel overwhelmed or uncertain about how to integrate ai into their existing practices. (joubert & jokonya, 2021) furthermore, access to ai technologies is often limited, particularly in rural areas where internet connectivity and digital resources are scarce (khan et al., 2020). without adequate training and access to technology, the potential benefits of ai cannot be fully realized, leaving many farmers at a disadvantage. infrastructure limitations infrastructure limitations pose a significant challenge to the adoption of ai in agriculture. in nigeria, inadequate transportation networks, unreliable electricity supply, and insufficient internet connectivity hinder the implementation of ai technologies (adesina et al., 2020). for instance, precision agriculture relies heavily on data global sustainability research global scientific research 103 collection and analysis, which requires robust internet access and reliable power sources to operate sensors and drones effectively. the lack of such infrastructure can lead to inefficiencies and limit the scalability of ai solutions in agricultural practices. addressing these infrastructure challenges is crucial for enabling farmers to leverage ai technologies effectively. policy and regulatory challenges the absence of supportive policies and regulatory frameworks can also impede the adoption of ai in agriculture. in many cases, existing agricultural policies do not adequately address the integration of new technologies, leading to uncertainty among farmers and investors (sullivan et al., 2020). additionally, regulatory barriers related to data privacy, intellectual property rights, and technology transfer can create obstacles for the development and implementation of ai solutions in agriculture (abiodun et al., 2018). policymakers must establish clear guidelines and support mechanisms to foster innovation and encourage the adoption of ai technologies in the agricultural sector. socioeconomic factors socioeconomic factors play a critical role in the adoption of ai in agriculture. many smallholder farmers in nigeria operate on limited budgets and face financial constraints that make it difficult to invest in new technologies (ibitoye et al., 2021). additionally, the lack of access to credit and financial services can further exacerbate these challenges, preventing farmers from adopting ai solutions that require upfront investments (kudama et al., 2021). moreover, cultural attitudes towards technology and innovation can influence farmers' willingness to embrace ai. in some cases, traditional farming practices may be deeply rooted, leading to resistance against adopting modern technologies (zhang et al., 2019). addressing these socioeconomic barriers is essential for promoting the successful integration of ai in agriculture. in conclusion, while ai has the potential to transform agriculture in nigeria, several challenges and barriers must be addressed to facilitate its adoption. enhancing technological literacy, improving infrastructure, establishing supportive policies, and addressing socioeconomic factors are critical steps toward enabling farmers to leverage ai technologies effectively. by overcoming these challenges, nigeria can harness the power of ai to promote sustainable agricultural practices and improve food security. empirical evidence of ai applications in nigerian agriculture the integration of artificial intelligence (ai) in agriculture is increasingly recognized as a transformative approach to achieving sustainable agricultural practices in nigeria. as shown below the table 2, this section discusses empirical evidence and case studies that illustrate the impact of ai on farming systems in nigeria, focusing on enhancing productivity, optimizing resource use, and promoting sustainability. the integration of ai in modern farming systems in nigeria is proving to be a catalyst for sustainable agricultural transformation. through precision agriculture, pest management, and optimized irrigation practices, ai technologies are enhancing productivity while promoting environmental sustainability. the empirical evidence and case studies presented highlight the potential of ai to address the challenges faced by the agricultural sector in nigeria, ultimately contributing to food security and economic development. as these technologies continue to evolve, their widespread adoption could significantly reshape the agricultural landscape in nigeria, fostering resilience and sustainability in the face of climate change and other challenges. the adoption of artificial intelligence (ai) in agriculture is steadily gaining momentum in nigeria, offering innovative solutions to enhance productivity, optimize resource management, and foster sustainable agricultural practices. this section outlines global sustainability research global scientific research 104 additional empirical evidence and case studies that highlight the effectiveness of ai in transforming farming systems across nigeria. table 2. empirical evidences of ai applications in nigerian agriculture sn technique description source 1 precision agriculture ai technologies, such as remote sensing and machine learning, are being utilized to implement precision agriculture in nigeria. farmers are using ai-driven drones to monitor crop health, assess soil conditions, and optimize irrigation practices. these technologies enable farmers to make data-driven decisions, leading to increased yields and reduced resource wastage. for instance, a study by ojo et al. (2020) reported that farmers employing precision agriculture techniques experienced yield increases of up to 30% compared to traditional farming methods, demonstrating the effectiveness of ai in enhancing agricultural productivity. ojo et al. (2020) 2 pest and disease management ai applications in pest and disease management have shown promising results in nigeria. machine learning algorithms are being developed to analyze images of crops and identify signs of pest infestations or diseases. a project implemented by the international institute of tropical agriculture (iita) utilized ai to develop a mobile application that allows farmers to upload images of their crops. the app analyzes the images and provides recommendations for pest control measures, significantly reducing the reliance on chemical pesticides and promoting more sustainable farming practices (iita, 2021) (iita, 2021) 3 irrigation optimization ai technologies are also employed to optimize irrigation practices in nigeria. smart irrigation systems that use ai algorithms to analyze weather data, soil moisture levels, and crop water requirements have been implemented in various regions. these systems help farmers apply the right amount of water at the right time, reducing water usage by up to 50% while maintaining crop health (abioye et al., 2021). this not only conserves water resources but also enhances the resilience of farming systems to climate variability. (abioye et al., 2021) 4 crop yield prediction ai has been instrumental in developing predictive models for crop yields. researchers at the university of ibadan utilized machine learning algorithms to analyze historical weather patterns, soil data, and crop performance metrics to forecast yields for various crops in nigeria. their findings indicated that farmers who utilized these predictive models were able to increase their yield accuracy by 25%, enabling better planning and resource allocation (ogunniyi et al., 2022). (ogunniyi et al., 2022) 5 smart pest management the integration of ai in pest management has shown significant promise. a study by adebayo et al. (2021) demonstrated the (adebayo et al. 2021) global sustainability research global scientific research 105 effectiveness of ai-based applications that leverage image recognition to identify pest species and recommend targeted treatments. by reducing the use of broad-spectrum pesticides, these applications contribute to more sustainable pest control methods, leading to healthier ecosystems and reduced chemical runoff. 6 market access and price forecasting ai technologies are also being employed to improve market access for farmers. platforms like agrodatatech use ai algorithms to analyze market trends and provide farmers with real-time information about crop prices and demand. this enables farmers to make informed decisions about when to sell their produce, ensuring they receive fair prices and reducing post-harvest losses (agrodatatech, 2021). (agrodatat ech, 2021) case studies illustrating ai's impact the integration of ai in modern farming systems in nigeria is proving to be a vital component in achieving sustainable agricultural transformation. through applications such as crop yield prediction, smart pest management, and improved market access, ai technologies are enhancing productivity and promoting environmentally friendly practices. the case studies presented illustrate the potential of ai to address the challenges faced by the agricultural sector in nigeria, contributing to food security and economic development. as ai technologies continue to evolve and become more widely adopted, they hold the promise of reshaping nigeria's agricultural landscape, fostering resilience amidst changing environmental conditions. 1. the nigerian agricultural transformation agenda (ata): the ata has incorporated ai technologies to enhance agricultural productivity and sustainability. through partnerships with tech companies, the initiative has introduced ai-driven platforms that provide farmers with real-time market information, weather forecasts, and best farming practices. this access to information has empowered smallholder farmers, enabling them to make informed decisions that improve their productivity and income (federal ministry of agriculture and rural development [fmard], 2019). 2. farmcrowdy: this nigerian agritech startup leverages ai to connect farmers with investors and provide them with the necessary resources and expertise. farmcrowdy uses data analytics to assess the viability of farming projects and match them with potential investors. by utilizing ai to streamline the investment process, the platform has facilitated the funding of numerous agricultural projects, contributing to increased productivity and sustainable farming practices across nigeria (farmcrowdy, 2020). 3. agrotech innovations: a notable case is the use of ai in soil health monitoring by agrotech innovations, which developed a soil testing kit that uses ai to analyze soil samples. the kit provides farmers with insights into soil nutrient levels and recommendations for fertilizer application. this technology has helped farmers optimize their input use, leading to improved crop yields and reduced environmental impact (agrotech innovations, 2021). 4. nigerian climate-smart agriculture program (ncsap): ncsap has implemented ai-driven models to promote climate-smart practices among farmers. the program employs machine learning algorithms to provide localized climate forecasts and recommendations for crop selection based on changing climate conditions. a global sustainability research global scientific research 106 case study in the benue valley showed that farmers using these ai tools experienced a 40% increase in resilience to climate-related challenges such as drought and flooding (ncsap, 2022). 5. hello tractor: this innovative platform connects smallholder farmers in nigeria with tractor owners through ai-driven mobile apps. by analyzing data on local farming practices and demand for mechanization, hello tractor optimizes the allocation of tractors to farmers who need them most. this approach has improved access to mechanization, reduced labor costs, and increased productivity for participating farmers (hello tractor, 2021). 6. nigerian institute for oil palm research (nifor): nifor has integrated ai technologies in oil palm cultivation to enhance yield and sustainability. utilizing ai-powered drones for monitoring oil palm plantations, researchers can identify areas needing attention, such as pest infestations or nutrient deficiencies. this targeted approach has resulted in a reported 20% increase in oil palm yield while minimizing the environmental impact (nifor, 2021). variations in ai adoption across nigeria's geopolitical zones nigeria's agricultural landscape is influenced by its division into six geopolitical zones: north central, north east, north west, south east, south south, and south west. as illustrated in table 3 below, the adoption of artificial intelligence (ai) technologies in agriculture varies significantly across these zones due to factors such as infrastructure, socio-economic conditions, and the predominant agricultural practices. socio-economic classes: large-scale vs. smallholder farmers the adoption of ai technologies in nigeria's agricultural sector also varies significantly between large-scale and smallholder farmers, influenced by their socio-economic status. large-scale farmers these farmers typically have greater access to capital, technology, and information. they are more likely to invest in ai technologies such as precision agriculture, predictive analytics, and automated systems. their ability to leverage ai can lead to increased productivity, better resource management, and enhanced market competitiveness (adebayo et al., 2021). for instance, large-scale farmers may use ai-driven drones for crop monitoring and ai algorithms for optimizing irrigation, significantly improving yields and reducing costs. smallholder farmers smallholder farmers, who constitute a significant portion of nigeria's agricultural workforce, often face barriers to ai adoption. these barriers include limited access to financial resources, inadequate infrastructure, and a lack of technical knowledge (oluwaseun et al., 2022). while some smallholder farmers may benefit from ai applications, such as mobile apps that provide weather forecasts and pest management advice, the overall adoption rate remains low. initiatives aimed at training and equipping smallholder farmers with ai tools are crucial for enhancing their productivity and sustainability (ogunniyi & adewumi, 2021).the adoption of ai in nigeria's agricultural sector is influenced by regional disparities and socio-economic factors. while large-scale farmers are more likely to embrace ai technologies, smallholder farmers face significant challenges that hinder their adoption. addressing these challenges through targeted policies, training programs, and infrastructure development is essential for fostering a more inclusive agricultural transformation in nigeria. global sustainability research global scientific research 107 table 3. ai adoption based on nigerian six geopolitical zones geopolitical zone details and sources 1 north central this zone, known for its diverse agricultural practices, exhibits a relatively higher level of ai adoption due to better access to technology and infrastructure. largescale farmers are more likely to adopt ai technologies for precision farming and yield prediction, as they have the resources to invest in such innovations (ogunniyi & adewumi, 2021). however, smallholder farmers may face challenges due to limited access to training and financial resources, resulting in slower adoption rates (oduwole et al., 2020). 2 north east the north east, characterized by significant agricultural potential, is hindered by insecurity and infrastructural deficits. ai adoption is likely low among both largescale and smallholder farmers due to these challenges. large-scale farmers may possess the means to implement ai solutions, but prevailing insecurity can deter investment. smallholder farmers, forming the backbone of the agricultural sector, often lack the necessary resources and support to adopt ai technologies (boko et al., 2022). 3 north west similar to the north east, the north west faces challenges such as poverty and limited access to technology. while large-scale farmers may adopt ai for specific applications, such as market analysis and pest management, the overall adoption rate remains low (ogunniyi et al., 2022). smallholder farmers are less likely to engage with ai due to a lack of awareness and access to training programs (eze et al., 2021). 4 south east the south east is known for its vibrant agricultural practices, particularly in cassava and yam production. ai adoption is gradually increasing, especially among largescale farmers who leverage ai for market access and supply chain optimization (okeowo & ndubuisi, 2021). however, smallholder farmers may struggle with adoption due to limited access to technology and financial constraints (igbokwe et al., 2022). 5 south south this zone, rich in natural resources, has witnessed some adoption of ai technologies, particularly in aquaculture and oil palm cultivation. large-scale farmers are more inclined to adopt ai for resource management and environmental monitoring (olagunju et al., 2021). in contrast, smallholder farmers often lack the necessary infrastructure and training, which hampers their ability to utilize ai effectively (ogunniyi et al., 2022). 6 south west the south west, with relatively better infrastructure and access to technology, has a higher rate of ai adoption among both large-scale and smallholder farmers. largescale farmers increasingly use ai for precision agriculture, while smallholder farmers are beginning to engage with ai through mobile applications that provide agricultural advice and market information (adedayo et al., 2021). technology readiness for ai adoption in agriculture the successful adoption of artificial intelligence (ai) in agriculture is significantly influenced by several factors, including internet connectivity, smartphone access, and farmers' willingness to embrace these technologies. global sustainability research global scientific research 108 understanding these elements is crucial for fostering an environment conducive to ai integration in farming practices. internet connectivity internet connectivity is a foundational requirement for the effective implementation of ai technologies in agriculture. reliable internet access enables farmers to utilize cloud-based ai applications, access real-time data, and communicate with agricultural experts. in nigeria, the disparity in internet connectivity across different regions poses a challenge. urban areas tend to have better internet infrastructure compared to rural regions, where many smallholder farmers operate. this digital divide can hinder the adoption of ai technologies, as farmers in less connected areas may struggle to access the necessary tools and information to leverage ai effectively (ogunniyi et al., 2022). enhancing internet connectivity in rural areas is essential for enabling farmers to benefit from ai-driven solutions, such as precision agriculture and market analysis tools. smartphone access smartphones play a critical role in facilitating ai adoption among farmers, particularly smallholders. with the proliferation of mobile technology, smartphones have become accessible to many farmers, providing them with a platform to access agricultural applications that utilize ai. these applications can offer valuable services, such as weather forecasts, pest management advice, and market price information. however, the extent of smartphone penetration varies across different socio-economic classes and regions. large-scale farmers are more likely to have access to advanced smartphones and the internet, allowing them to utilize sophisticated ai applications. in contrast, smallholder farmers may have limited access to smartphones, which can restrict their ability to engage with ai technologies (adebayo et al., 2021). bridging this gap through targeted initiatives, such as providing affordable smartphones and training on their use, can enhance ai adoption among smallholder farmers. farmers' willingness to adopt ai the willingness of farmers to adopt ai technologies is influenced by several factors, including perceived benefits, trust in technology, and previous experiences with agricultural innovations. farmers who recognize the potential advantages of ai, such as increased productivity and reduced labor costs, are more likely to embrace these technologies. however, skepticism about the reliability and effectiveness of ai can hinder adoption, particularly among smallholder farmers who may have limited exposure to technology (oluwaseun et al., 2022). education and awareness campaigns that demonstrate the practical benefits of ai in agriculture can help build trust and encourage adoption. additionally, involving farmers in the development and testing of ai solutions can foster a sense of ownership and increase their willingness to adopt these technologies (eze et al., 2021). the readiness for ai adoption in agriculture is significantly influenced by internet connectivity, smartphone access, and farmers' willingness to embrace new technologies. addressing the challenges associated with these factors is essential for promoting the effective integration of ai in nigeria's agricultural sector. by improving internet infrastructure, enhancing smartphone accessibility, and fostering a positive attitude towards ai, stakeholders can create an environment that supports the widespread adoption of ai technologies, ultimately leading to increased agricultural productivity and sustainability. conclusion this study has explored the role of artificial intelligence (ai) in transforming agriculture, particularly in the context of nigeria. the findings indicate that ai applications, including precision agriculture, crop monitoring, pest and disease detection, and resource optimization, have the potential to significantly enhance agricultural productivity global sustainability research global scientific research 109 and sustainability. notably, the adoption of ai can lead to increased yields, reduced environmental impacts, improved food security, and economic benefits for farmers. however, the study also identified several challenges and barriers to ai adoption, including technological literacy, infrastructure limitations, policy and regulatory challenges, and socioeconomic factors. these findings underscore the need for a multifaceted approach to facilitate the integration of ai technologies in agriculture. the implications of this study for policy and practice are substantial. policymakers must recognize the transformative potential of ai in agriculture and create an enabling environment that supports technology adoption. this includes investing in infrastructure development, such as reliable internet connectivity and electricity supply, which are critical for the effective implementation of ai solutions. moreover, policies should promote agricultural innovation by providing incentives for research and development in ai technologies tailored to local conditions and challenges. additionally, enhancing technological literacy among farmers is essential. training programs that focus on the practical applications of ai in agriculture should be developed and implemented, particularly in rural areas. these programs should aim to empower farmers with the knowledge and skills necessary to leverage ai tools effectively, thus increasing their confidence and willingness to adopt new technologies. furthermore, establishing clear regulatory frameworks that address data privacy, technology transfer, and intellectual property rights is crucial to fostering innovation and collaboration between stakeholders in the agricultural sector. future research should focus on several key areas to further advance the understanding of ai in agriculture. firstly, longitudinal studies that assess the long-term impacts of ai adoption on agricultural productivity and sustainability are necessary. these studies can provide valuable insights into the effectiveness of ai technologies over time and the factors that contribute to successful implementation. secondly, research should explore case studies of successful ai adoption in different agricultural contexts, particularly in developing countries. understanding the specific conditions and strategies that facilitated these successes can inform best practices and guide future initiatives. additionally, investigating the socio-cultural factors that influence farmers' attitudes towards technology adoption is vital. future studies should examine how cultural beliefs and practices interact with technology use, as this can provide insights into overcoming resistance to new innovations. lastly, interdisciplinary research that integrates perspectives from agriculture, technology, economics, and social sciences can lead to a more comprehensive understanding of the challenges and opportunities associated with ai in agriculture. such research can support the development of holistic solutions that address the complex issues faced by farmers in nigeria and similar contexts. in a nutshell, while the potential of ai in transforming agriculture is immense, realizing this potential requires concerted efforts from policymakers, researchers, and practitioners. by addressing the identified challenges and facilitating the adoption of ai technologies, nigeria can move towards a more sustainable and productive agricultural future. declaration acknowledgment: we sincerely acknowledged the

climate change adaptation; adaptive capacity; climate resilience; smallholder farmers; climate change introduction agriculture is among the most climate sensitive sectors of the global economy, which makes it highly vulnerable to its intensifying effects (clapp, newell and brent, 2018). global agricultural production systems experience changes due to temperature variations and precipitation patterns along with rising frequency and severity of droughts, floods and heatwaves (handmer et al., 2012). the changes in weather patterns threaten food security, rural livelihoods, and the economic stability of countries that depend on agriculture (ipcc, 2022). estimates suggest that a 1°c rise in global temperature may reduce yields of major crops, such as maize, soybeans, and cotton by approximately 7% (lobell, schlenker, and costa-roberts, 2011). major food-producing regions now global sustainability research global scientific research 19 face increasing chances of simultaneous climate shocks which heighten systemic vulnerabilities in global food supply chains (kornhuber et al., 2023). in this context, adaptation has become a central pillar of agricultural resilience strategies. farmers, particularly in vulnerable areas, are increasingly engaging in practices aimed at mitigating climate-related threats. these include investments in drought-resistant crop varieties, improved irrigation systems, implementation of climatebased planting schedules and soil conservation techniques (ignaciuk and mason-d’croz, 2014). however, the economic incentives, costs, and long-term benefits associated with these investments are unclear. a farmer’s risk assessment along with their financial situation and predicted climate conditions determine their investment decisions toward adaptation measures (eitzinger, binder, and meyer, 2018). several empirical studies have analyzed the impact of climate change on agriculture and adaptation techniques (eka suranny, gravitiani and rahardjo, 2022; pathak, aggarwal and singh, 2012). however, there is a relative scarcity of formal theoretical models that capture the dynamic nature of farmers’ decision-making under climate uncertainty. traditional production models present climate risk as an exogenous factor without showing how farmers can reduce their exposure through direct investments into risk reduction measures (finger and schmid, 2007). furthermore, adaptive capacity models in the literature represent static conditions rather than agents' timedependent choices regarding adaptation capacity (allison et al., 2023). this study addresses these gaps by developing a dynamic stochastic model, which represents farmers’ decisions regarding their agricultural production and adaptive capacity investments across time periods. the model introduces a climate-sensitivity function which shows diminishing sensitivity as adaptive investment levels rise. adaptive capacity is treated as a stock variable that depreciates over time and requires periodic investments to maintain or enhance resilience. the model incorporates climatic uncertainty through stochastic climate shocks which directly impact production while demonstrating the connection between environmental unpredictability and adaptive choices. the primary contribution of this paper consists of integrating adaptive investment into a dynamic optimization framework. it highlights the trade-off between short-term agricultural output and long-term resilience, depicting how forward-looking farmers may choose to allocate resources between consumption and adaptation under uncertainty. the model provides theoretical insights about how changes in climate volatility and risk preferences along with adaptation costs shape optimal behavior. the proposed framework serves as a foundation to understand when and how policy instruments such as subsidies, insurance mechanisms and public investments in adaptation infrastructure influence private investment decisions. the structure of the paper is as follows. introduction is followed by a summary of the current literature about the impact of climate change on agriculture, adaptation strategies and theoretical modeling frameworks. the next section explains the design of the dynamic stochastic model while showing how the farmer makes their optimal choices. it is followed by the uses, comparative statics and theoretical analysis to examine the model's outcomes. the next section discusses the policy relevance of the findings. the final section provides the conclusion of this study along with proposed research directions for future studies. literature review the intersection of agricultural economics and climate change has increasingly gained attention in literature, driven by mounting evidence of the vulnerability of food systems to environmental stressors. this literature review discusses the theoretical and conceptual frameworks that inform our understanding of climate impacts on agriculture and the role of adaptive investments, highlighting existing gaps that motivate the model developed in this study. global sustainability research global scientific research 20 climate change and agricultural production multiple studies demonstrate how climate change causes negative effects on agricultural yields and farm income. lobell and field (2007) show that rising temperatures result in yield reductions across multiple staple crops, particularly in tropical and subtropical climates. u.s. crop yields strongly respond to temperature extremes and yield reductions. these effects become more severe beyond certain heat thresholds (schlenker and roberts, 2009). these studies highlight the importance of considering both gradual climate changes and acute weather shocks in agricultural planning and policy development. however, most of the early research failed to examine farmer behaviour in response to rising risk because it treated climatic variables as exogenous and static (agba et al., 2017; moore, baldos, and hertel, 2017; xiang et al., 2022; baris-tuzemen and lyhagen, 2024). this limitation led to calls for more dynamic and micro-funded approaches that may endogenize the role of decision-making under uncertainty (barrett et al., 2007; choquettelevy et al., 2024). modeling adaptation to climate change agricultural adaptation consists of both reactive and proactive strategies directed at reducing vulnerability to climate-related changes. these adaptation approaches include adopting new technology such as drought-resistant seeds and infrastructure investments in irrigation systems and institutional strategies with insurance mechanisms. various theoretical models have approached adaptation employing various frameworks. mendelsohn et al. (1994) introduce the ricardian framework, which evaluates land value as a function of climate while controlling for adaptation implicitly. this method captures long-term equilibrium impacts, but it does not explicitly demonstrate adaptation processes. difalco and perrings (2005) employ real options theory, which allows them to analyze the timing of adaptive investment under uncertain conditions because such choices capture irreversibility alongside path-dependent characteristics. moreover, dynamic programming models serve to analyze the process of sequential choice in situations where outcomes remain uncertain. antle and capalbo (2010) recommend a risk-based approach which helps evaluate farm-level decisions by taking into account weather uncertainty and soil variations. these models, however, often lack a mechanism in resilience as a capital stock that evolves over time. adaptive capacity as a dynamic stock variable existing research focuses on representing adaptive capacity as both a static outcome and a dynamic stock that is augmentable and subject to depreciation. a system's ability to withstand shocks grows with adaptation capital including knowledge, infrastructure, and physical assets but demands continued investment for sustainability (fankhauser and burton, 2011). however, few theoretical models integrate adaptation capital into farmers’ decision problems. exceptions include the work of cai et al. (2011), who presents a model for water infrastructure investments under climate risk as a notable exception in this regard. similarly, robert, bergez and thomas (2018), develop a stochastic dynamic model to analyze farmers’ decision concerning irrigation investments, water application rates, and crop choices. moreover, kalthof et al. (2025) suggest an agent-based model, the geographic, environmental and behavioral (geb) model, coupled with a hydrological model to examine farmers’ adaptive behaviors under long spells of droughts. these models, however, do not apply to wider agricultural adaptation cases and rarely provide mechanisms for stochastic climate changes that trigger endogenous responses. global sustainability research global scientific research 21 gaps in the literature and contributions of this paper the existing literature lacks a generalizable dynamic framework to depict how farmers simultaneously make production and investment decisions in the face of climate-induced uncertainty. furthermore, most existing models either assume perfect foresight or treat adaptation as an exogenous variable instead of a strategic choice. this paper contributes to the literature by developing a dynamic stochastic optimization model that explicitly integrates resource allocation decisions between productive agricultural activities and the accumulation of adaptive capacity. climate shocks are modeled as a stochastic process, influencing output through a climate sensitivity function that captures the non-linear effects of environmental variability. adaptive capacity is treated as a stock variable that enhances resilience to climate shocks but is subject to depreciation over time, necessitating sustained investment to maintain its protective benefits. this framework integrates risk, investment dynamics and endogenous adaptation, which provides new theoretical insights for climate-resilient agricultural decision-making. model formulation overview the section introduces a dynamic stochastic model in which a representative farmer allocates resources between agricultural production and investments in adaptive capacity. the model captures the intertemporal trade-offs farmers face under climate uncertainty and shows how investments in adaptation serve as a buffer against climateinduced output losses. adaptive capacity is modeled as a dynamic stock which enhances resilience but depreciates over time. climate shocks are introduced as stochastic disturbances that influence agricultural output. economic environment the model considers a risk-averse representative farmer, operating over an infinite time horizon, denoted as 𝑡 = 0, 1, 2, . . . . .. at each period, the farmer receives revenue from agricultural production and decides the portion of the available income to allocate toward consumption, reinvestment in agricultural inputs, and adaptive investment. let: ● 𝑌𝑡 be the agricultural output at time t ● 𝐴𝑡 denote the stock of adaptive capacity ● 𝜃𝑡 be the stochastic climate shock at time t ● 𝐼𝑡 𝑎 denote investment in adaptive capacity ● 𝐼𝑡 𝑝 denote investment in productive capital ● 𝐶𝑡 denotes consumption the farmer maximizes expected lifetime utility. 𝐸0 ∑ 𝛽𝑡𝑈(𝐶𝑡) ∞ 𝑡=0 subject to global sustainability research global scientific research 22 budget constraint 𝑌𝑡 = 𝐹 (𝐾𝑡, 𝐴𝑡 , 𝜃𝑡) = 𝜙 (𝐴𝑡 , 𝜃𝑡) . 𝑓 (𝐾𝑡) 𝑌𝑡 = 𝐶𝑡, 𝐼𝑡 𝑎, 𝐼𝑡 𝑝 2. adaptive capital accumulation 𝐴𝑡+1 = (1 − 𝛿𝑎)𝐴𝑡 + 𝐼𝑡 𝑎 3. productive capital accumulation 𝐾𝑡+1 = (1 − 𝛿𝑝)𝐾𝑡 + 𝐼𝑡 𝑝 where: 𝛽 ∈ (0, 1) is the discount factor, 𝑈 (𝐶𝑡) is a crra utility function, 𝑈 (𝐶) = 𝐶1−𝜎 1−𝜎 , 𝜎 > 0 𝛿𝑎 and 𝛿𝑝 are depreciation rates of adaptive and productive capital respectively, 𝑓(𝐾𝑡) is a neoclassical production function, 𝜙 (𝐴𝑡 , 𝜃𝑡) is the climate resilience function, 𝜃𝑡~ 𝑖. 𝑖. 𝑑 θ is the stochastic climate shock the climate resilience function a novel element of this model is the climate resilience function 𝜙 (𝐴𝑡 , 𝜃𝑡), which determines the impact of climate shocks on agricultural output, conditional on adaptive capacity. the model proposes: 𝜙 (𝐴𝑡 , 𝜃𝑡) = exp (−𝛾𝜃𝑡 𝑒−𝜂𝐴𝑡) where: 𝛾 > 0 is a shock sensitivity parameter, 𝜂 > 0 is the effectiveness of adaptive capital this function ensures that in the absence of adaptation (𝐴𝑡 = 0), climate shocks significantly reduce agricultural output. as 𝐴𝑡 increases, the effect of 𝜃𝑡 on output is mitigated. the exponential form ensures diminishing marginal returns to adaptation, a property consistent with empirical findings by fankhauser and burton (2011). the farmer’s optimization problem substituting into the budget and dynamic constraints, the farmer solves: 𝐸0 ∑ 𝛽𝑡𝑈 ∞ 𝑡=0 𝐶𝑡 1−𝜎 1 − 𝜎 subject to: 𝐶𝑡 + 𝐼𝑡 𝑎 + 𝐼𝑡 𝑝 = exp (−𝛾𝜃𝑡 𝑒−𝜂𝐴𝑡) . 𝑓 (𝐾𝑡) 𝐴𝑡+1 = (1 − 𝛿𝑎)𝐴𝑡 + 𝐼𝑡 𝑎 𝐾𝑡+1 = (1 − 𝛿𝑝)𝐾𝑡 + 𝐼𝑡 𝑝 this dynamic problem can be solved using value function iteration or other numerical techniques. however, in this study, the focus is on theoretical properties and implications of the model rather than explicit numerical solutions. global sustainability research global scientific research 23 comparative statics and theoretical implications the comparative statics analysis examines how changes in key parameters like the variance of climate shocks, the depreciation rate of adaptive capital, and the functional curvature of the climate sensitivity function affect optimal investment behavior and long-term resilience. the model yields several testable implications. 1. increased climate variability increases adaptive investments an increase in the variance of 𝜃𝑡 elevates the marginal value of adaptation capital 𝐴𝑡, thereby inducing higher optimal adaptation investment 𝐼𝑡 𝑎. 2. trade-off between resilience and short-term output greater allocation of current income to 𝐼𝑡 𝑎 reduces productive investment and output in the short run but enhances resilience and expected future output. 3. depreciation of adaptive capacity necessitates sustained investment given 𝛿𝑎 > 0, resilience can only be maintained through continuous reinvestment; absent this, the system gradually becomes more vulnerable over time. 4. diminishing marginal returns to adaptation the function form of 𝜙 implies that beyond a certain level of 𝐴𝑡, additional adaptation investment yields minimal incremental protection, indicating the existence of an optimal adaptive capital stock. theoretical analysis and policy implications optimal adaptive investment and the role of climate risk in the theoretical model, farmers face a dynamic trade-off between agricultural production in the short run and long-term resilience to climate shocks. the model shows that optimal investment in adaptive capacity (𝐼𝑡 𝑎) increases in both the perceived severity and variability of climate risk. as climate shocks (𝜃𝑡) become more intense, the marginal benefit of adaptation increases due to its role in mitigating output volatility. this aligns with theoretical expectations from risk management literature, suggesting that risk-averse agents will increase precautionary investments upon exposure to higher uncertainty (barrett et al., 2017). a key insight from the model is that the climate resilience function 𝜙 (𝐴𝑡 , 𝜃𝑡) transforms the nature of risk exposure. specifically, adaptive capacity acts as a form of resilience capital that flattens the marginal damage curve of climate shocks. the exponential decay function exp (−𝛾𝜃𝑡 𝑒−𝜂𝐴𝑡) implies that investments in 𝐴𝑡 can considerably reduce output losses at lower levels of adaptation. however, diminishing marginal returns imply that further investment becomes less effective. this creates a critical policy window for identifying the optimal range of adaptation investment, beyond which public subsidies or joint adaptation strategies may be needed to avoid inefficient over-investment. temporal trade-offs: short term costs and long-term gains another vital implication is the intertemporal trade-off embedded in the farmer’s decision-making. increased investment in adaptive capacity in the current period (𝐼𝑡 𝑎) reduces the resources available for immediate consumption or productive capital investment (𝐼𝑡 𝑝 ), potentially resulting in a reduction of short-term output. however, by increasing future resilience, such investments reduce the expected damage from future shocks and smooth income over time. this supports the idea that adaptation policy needs to focus on long-term welfare global sustainability research global scientific research 24 maximization rather than short-term output maximization, a principal highlighted in sustainable development frameworks (hallegatte et al., 2011). policy implications for agricultural adaptation under climate change based on the model, several important policy implications can be drawn: targeted adaptation incentives when policymakers assess diminishing marginal returns in adaptation efforts, they need to identify specific threshold levels of adaptive capacity beyond which additional investment yields limited output stabilization. investments in adaptation infrastructure require specific subsidies and grants to maintain economic justification below this established threshold. dynamic investment strategies since adaptive capacity depreciates over time, therefore one-time investments are insufficient. policymakers need to encourage continuous and dynamic investment strategies. this may involve multi-year budgeting for adaptation or institutional arrangements that mandate recurrent evaluations and top-ups of adaptation stock. integration with risk-transfer mechanisms the model confirms that adaptation and insurance work together as mutual components rather than as alternative solutions. the implementation of adaptive investments decreases probable losses yet preserves some level of risk exposure. when adaptation policies unite with weather-indexed insurance and disaster risk financing mechanisms, it results in better welfare outcomes (carter et al., 2014). equity and distributional considerations since adaptive capacity tends to be higher in capital-rich contexts, inequalities in resilience may emerge between regions and/or farmers. the model demonstrates that market mechanisms may reinforce vulnerability of smallholder farmers unless corrective redistribution measures are implemented. this support calls for international climate finance mechanisms along with domestic redistributive policies to reduce adaptation gaps (ipcc, 2022). broader theoretical implications from a theoretical perspective, this model contributes to the literature by embedding a dynamic resilience framework directly into agricultural production under conditions of uncertainty. traditional production functions under risk conditions typically depend on exogenous shocks which static effects (rosenzweig and binswanger, 1993). the model provides a new approach to climate adaptation behavior analysis by including an endogenous resilience mechanism. thus, opening the door for richer models’ development for climate adaptation behavior that can be extended to encompass behavioral biases, credit constraints and multi-agent interactions. the model demonstrates that adaptation operates as an economic choice which optimizes itself rather than functioning as a mere policy instrument. this insight provides the potential to merge different adaptation research global sustainability research global scientific research 25 streams through a unified microeconomic framework, which may offer new opportunities for better empirical model calibration and simulation-based policy design. extensions and future research directions incorporating behavioral dimensions into adaptation decisions the model presents a rational, forward-looking farmer who optimizes over time under climate risk but real-world decisions are often affected by cognitive biases along with limited foresight and imperfect information. behavioral economics suggests that farmers may underinvest in adaptive capacity on account of present bias, ambiguity aversion and/or risk misperception (duflo, kremer, and robinson, 2011; tversky and kahneman, 1992). a vital extension of this model may involve incorporating behavioral parameters, including hyperbolic discounting and subjective probability weighting, into the farmer's utility function. such an analysis would help explain observed adaptation inertia among farmers despite rising climate risks and provide policy recommendations about behavioral modifications through framing techniques, default options and capacitybuilding interventions. furthermore, the model could be extended to account for social learning and peer effects in adaptation investment decisions. research shows that farmers generally adapt new technologies based on what they observe or through local social networks (conley and udry, 2010). incorporating such dynamics into the model through agent-based simulations or network-based optimization frameworks would help identify tipping points in adaptation uptake and highlight collective resilience limits at the community level.\ introducing market imperfections and credit constraints a crucial area for future work is to introduce market imperfections, particularly insurance market failures and credit constraints. developing regions have smallholder farmers who may be unable to invest in adaptive capital due to liquidity constraints (dercon and christiaensen, 2011). the current model assumes full access to intertemporal budget smoothing; relaxing this assumption by borrowing restrictions or high interest rates may result in a more realistic approach for climate adaptation policy design. this extension could also enable researchers to study the effects of public adaptation subsidies on private investment behavior. for instance, the provision of subsidies to farmers who need credit allows them to reach optimal investment levels which then attracts additional private investment. alternatively, poorly designed subsidies may displace private initiative, resulting in overreliance on government support. integrating multiple climatic and environmental stressors the current model identifies climate shocks as the primary environmental risk factor. however, farmers may face compound risks, encompassing soil degradation together, pest outbreaks and market volatility. future extensions could model multi-dimensional environmental shocks that impact adaptive capacity in different ways. for instance, resilience to drought may not translate to pest infestation resilience, and investments in one form of adaptive capacity may have trade-offs or synergies with another. this line of research may benefit from a multi-shock framework to model adaptive capacity through specific stressor-oriented asset portfolios. through this approach policymakers and researchers can develop optimal diversification strategies for resilience-building while creating a theoretical basis for climate-agricultureenvironmental planning integration. global sustainability research global scientific research 26 spatial dynamics and regional spillovers a promising direction involves spatializing the model to account for regional heterogeneity and spillover effects. adaptive investments generate public benefits in local areas because they involve projects such as watershed management, community irrigation systems and cooperative pest control. extending the model with spatial externalities would enable researchers to examine coordination issues and the design of cooperative adaptation strategies. furthermore, spatial modeling may also integrate climate migration dynamics. failure of adaptation efforts in particular areas due to extreme climate conditions may force people to move as a coping mechanism the incorporation of adaptation decisions into a spatial general equilibrium model would reveal how agricultural labor markets, regional development and land use patterns change through climate adaptation and migration processes (feng, krueger and oppenheimer, 2010). empirical calibration and simulation-based policy testing future work could involve empirical calibration of the model using data from reliable sources like the world bank climate change knowledge portal combined, faostat and lsms (living standards measurement study) datasets. by assigning real-world parameter values, the model would enable the simulation of policy interventions such as adaptation subsidies, climate insurance schemes and resilience-indexed credit to evaluate their welfare effects across various farmer profiles and climatic zones. the use of simulation-based methods would enable researchers to conduct counterfactual analysis and sensitivity testing, which may help merge theoretical models with practical policy applications. these calibrated models can serve as policy laboratories that examine the evolution of adaptive behaviors under various climate scenarios and institutional constraints. conclusion agricultural lies at the nexus of food security and climate vulnerability, making it one of the most critical sectors for proactive climate adaptation. this paper introduced a dynamic theoretical framework which integrates endogenous investment in adaptive capacity into the decision-making process of a risk-averse farmer under stochastic climate shocks. the framework differs from traditional exogenous resilience models by showing adaptation as an intertemporal process which enables us to study farmers' decisions between productive capital and resilience-building investments under conditions of uncertainty. the model yields several crucial insights. firstly, the model demonstrates that adaptive capacity acts as resilience capital which reduces negative effects of climate variability on agricultural output. the demonstrates the importance of adaptation not only as a reactive strategy but also as a forward-looking investment decision. secondly, the marginal returns from adaptation investment decrease after reaching specific levels which indicates important investment barriers that lead to substantial welfare benefits below the thresholds and potentially inefficient investment above them. the finding has direct implications for the design of targeted adaptation subsidies and the prioritization of policy interventions. the model also shows how investment decisions regarding resilience between current periods create long-term benefits while reducing short-term output and consumption levels. the trade-off between adaptation costs and long-term benefits demonstrates the necessity of patient capital along with long-term planning in adaptation financing. it provides a strong rationale for public intervention when private actors face liquidity constraints or behavioral biases that result in insufficient investment for resilience. global sustainability research global scientific research 27 the paper provides a roadmap for future research. multiple promising model extensions are proposed, which involve behavioral aspects together with imperfect credit markets, spatial relationships and combined climate risk factors. extending the model allows both theoretical depth enhancement and practical model application improvement for real-world policy assessments. simulation-based testing alongside empirical calibration of the model would help link theoretical findings to practical applications thus creating a useful tool for climate policy assessment. the study contributes to a growing body of literature emphasizing the importance of adaptive capacity as a vital component in agricultural systems. as climate change intensifies and climate shocks become more frequent and severe, the resilience of agricultural livelihoods will increasingly depend on the ability of farmers and supporting institutions to predict, absorb and recover from environmental stressors. the theoretical framework developed in this paper provides a foundation for understanding this adaptive behavior and offers a conceptual guide for designing efficient and equitable climate adaptation policies. declaration acknowledgment: n/a funding: n/a conflict of interest: the author declares that there is no conflict of interest. ethics approval/declaration: n/a consent to participate: n/a

environmental sustainability; social well-being; sustainable livelihood; tourism development; philippines. introduction husain (n.d.) argued that tourism industry evolves at the slowest pace compared to other sectors of the worldwide economy. moreover, it is significant in the creation of jobs, economic development and exchange of cultures. however, there exist some negative effects of tourism on town’s social fabric, culture and even ecosystems. before its transformation into an ecotourism zone, tagalag fishing village in valenzuela city faced a series of challenges that hindered its potential for growth and development. the village was primarily known for its declining fish ponds, which had long been neglected and were commercially non-viable. the lack of infrastructure, tourism facilities, and a clear economic plan left the community struggling with limited livelihood options and stagnant local businesses. the area’s natural resources, once a source of income for residents, were underutilized, and there was little to no tourism activity, leaving the fishponds and surrounding environment in disrepair. additionally, the community lacked a unified vision for development, and environmental sustainability was not a priority. this lack of coordination and economic diversification created a sense of stagnation in the village, making it difficult for local residents to benefit from their natural resources and leading to missed opportunities for growth and improvement. therefore, an alternative process for tourism growth called sustainable tourism has emerged with emphasis on conserving natural marine resources while encouraging economic progress. global sustainability research global scientific research 31 in recent years, sustainable livelihood tourism development (sltd) became a byword in the philippines as several initiatives were adopted to encourage community-based tourism. one example is the establishment of valenzuela city’s tagalag fishing village ecotourism zone which is aimed at promoting sltd through exploiting traditional fishing practices of its inhabitants. the major purpose of the study was to probed into tagalag fishing village ecotourism zone’s sustainable tourism development, its economic impact on the local people and possible future expansion. it gathered qualitative data which was analyzed using various techniques as well as provided a background of the tagalag fishing village ecotourism zone such as location and history. in addition, this part also indicated what the project aims at and how it relates to sustainable tourism. this research has also looked at the economic effects of this project on people living in that area. this part evaluated several information on employment opportunities, income generating activities as well as total economic growth since commencement of the project; it will also examine opinions from residents regarding whether or not they believe in success potential for more growth. semi-structured interviews and survey questionnaires are two examples of qualitative data gathering techniques that were used to get data about how the community sees the impacts of this project upon their individual lives and communities at large. hence, this investigation gave an illustration of how sustainable livelihood tourism development may be used in order to promote economic prosperity while still conserving aquatic natural resources. the outcomes of this research could be used in the formation of future trends regarding tourism as a sector in the philippines and other countries that are still developing. to discover some ways through which sltd can be supported in their locality by means of examining tagalag fishing village as a potential tourist destination. it also looked into the issues facing sltd within tagalag and presented recommendations for policy makers, community leaders and tourism practitioners on making the area more sustainability inclined and economically prosperous. literature review economical tourism improvement arranging is the way to avoid chaotic tourism advancement and oversee the day-by-day changes that happen in a turbulent environment (mcdonald, 2009). arranging for economical tourism improvement is really related to arranging for natural preservation and different ponders and analyses are carried out some time recently choosing on the heading of improvement. all these exercises are done to dodge serious misuse of assets particularly zones without respect to asset preservation. (najdeska et al., 2012). with affect evaluation and recreation becoming progressively vital in tourism advancement, gis plays a part in exploring natural conditions, evaluating the reasonableness of locales for the proposed improvement, recognizing clashing interfaces, and modeling connections (bahaire & white, 1999). enhancing the community's economic and social stand while minimizing damaging effects on the local surroundings, ancestry, and culture is the primary objective of tourist innovation. it also aims to raise awareness and education about environmental and political issues among tourists and locals. tourism is a dynamic and promising industry worldwide. in order to balance the social, economic, and environmental ambitions of the community, strict and sustainable planning and growth are required. retaining a high degree of customer satisfaction, ensuring visitors have a meaningful experience, expanding consumer comprehension of sustainability difficulties, and inspiring sustainable tourism practices are all important tasks for the management of sustainable tourism development. (jasinskas et. al, 2020). the negative impacts of human activities on the natural environment through resource extraction and waste generation are well known. a possible way to reduce environmental pressure and use resources more efficiently is circular economy. this concept is based on technological innovations that can create economic benefits while being environmentally friendly. circular economy has gained popularity among public, private and civic organizations and also in academic circles. many people are reaching for extreme action to ease the threat of global warming, but beckerman (2020) claims that this is a mistaken diversion from the more severe environmental problems that global sustainability research global scientific research 32 developing nations face. since the 1980s, the tourism literature has called for the inclusion and involvement of local communities in tourism; residents see it as a critical resource in sustaining the product (hardy et al., 2002). the ability of a community to bounce back and reorganize in the face of difficulties while preserving a sense of continuity is referred to as community resilience. mutuality is achieved when members of the community have a firm understanding of who they are both inside and outside of the community. to put it simply, participants recognize how they relate to and differ from the community. people in the community like predictable, wellorganized patterns, but they work best when there is a healthy mix of flexibility and modest structure. community resilience is necessary for tourism, which entails valuing and strengthening many types of community capital. these types of capital support community members' cooperation, ingenuity, and camaraderie (butler, 2018). according to deshler (2011), while ecotourism has the potential to provide local economic benefits and support conservation, its effectiveness as a tool for both conservation and community development remains mixed. findings indicated that legal restrictions had a greater impact on reducing deforestation and hunting than tourism itself, and while direct employment in ecotourism was linked to pro-conservation practices, broader environmental benefits were more strongly associated with indirect effects. it concludes that ecotourism is most effective when integrated into a larger conservation strategy, with scale playing a key role in determining its benefits and drawbacks. anup kc (2017) examines ecotourism as a strategy for sustainable development, focusing on its role in biodiversity conservation, poverty reduction, and economic growth through low-impact tourism. highlighting various forms of ecotourism, such as community-based and cultural, kc emphasizes its positive impacts on environmental protection, social stability, and local economic opportunities. in nepal, ecotourism has contributed to forest conservation, community empowerment, and cultural preservation, particularly for women. however, challenges remain, especially in the early stages of development, where training in areas like tour management and sustainable resource use is crucial to ensuring long-term success. methodology research design the researchers used different resources in this study, such as published and unpublished documents, survey questionnaires, interviews, and government data documents. the

articulation is 1.44, which falls into the "strongly oppose this idea" category. in any case, the standard deviation for this articulation is 0.75, which proposes that there is more variety in reactions to this articulation than to the other statements. commerce undertakings are not the as it were openings that open entryways to the community of tagalag. the barangay captain too expressed that "not as it were modern and progressing food-related businesses, toda, and open spaces for stopping are too unused openings that were presented to the community due to tagalag fishing village''. he communicated that with individuals coming in tagalag, toda tricycle administrators and drivers affiliationwith individuals coming in and out of barangay tagalag for its excellent sceneries, toda or the tricycle administrators and drivers affiliation creates pay through tourism. the tricycle administrators and drivers association (toda) within the philippines plays a noteworthy part in neighborhood tourism, contributing to the financial well-being of its individuals and the community. tricycles are a common mode of transportation in numerous philippine towns and cities, especially in zones with contract roads where bigger vehicles may battle to explore. these three-wheeled vehicles, frequently motorbikes with sidecars, serve as a helpful means of transport for both local people and visitors. this vital situating permits tricycle administrators to capitalize on the convergence of guests. tricycle administrators regularly act as casual neighborhood guides, recommending restaurants, shops, and other attractions to visitors which too makes a difference to other businesses in barangay tagalag. global sustainability research global scientific research 41 local tourism industry this area will examine how the tourism is significant to valenzuela city and to barangay tagalag. the results were shown through the format of questions and their corresponding answers interpreting the considerations and perspectives of the experts who are known as officer in charge of valenzuela city's social issues and tourism improvement. "how important is tourism in community improvement?” with the question in mind, the expert stated that tourism is basic since it may be a frame of financial action. consider how improvement takes place— through financial movement activity action. there are numerous sorts of financial exercises, extending from huge companies looking for financial specialists to contribute, but this depends on the area. "can you envision industrial facilities in tagalag? no, it doesn't fit. what economic activities are conceivable in tagalag? tourism could be a plausibility. on the off chance that your town includes a shoreline with a wonderful coastline, what financial movement is doable? tourism. in the event that you're within the mountains, what financial movement is conceivable? if it's distant from civilization with little else to see, it might not be tourism; it can be mining". it continuously depends on the assets accessible within the range. tourism is just one of the few financial exercises. address number 2 to the master is "how vital is tourism in community improvement?” with the address in intellect, the master expressed that tourism is basic since it could be a frame of financial action. consider how advancement takes place—through financial movement. there are numerous sorts of financial exercises, extending from expansive companies looking for financial specialists to contribute, but this depends on the area. "can you envision industrial facilities in tagalag? no, it doesn't fit. what financial exercises are conceivable in tagalag? tourism is a plausibility. in case your town incorporates a shoreline with an excellent coastline, what economic action is doable? tourism. on the off chance that you're within the mountains, what financial movement is conceivable? in the event that it's distant from civilization with little else to see, it might not be tourism; it may well be mining". it always depends on the resources available within the range. tourism is one of the few financial exercises." tourism isn't significant in valenzuela" the expert's beginning reply to the third question "how significant is tourism to the business and employment of the inhabitants of valenzuela?” area is not a visitor goal, not at all like other areas and communities where tourism could be a major portion of their economy. "to determine the noteworthiness of tourism, for example in an area, on the off chance that their tourism wage is 1 million and the entire pay is 3 million, at that point ⅓ of their add up to salary comes from tourism. that's critical, and that's how you see it. in our case, as it were a little rate can be considered, fair a perception since there's no genuine tally however due to the trouble in computing tourism" for the final portion of this segment, the 135 respondents of the community were asked how the opening of tagalag fishing town to the open contributed to the source of pay for regular needs. the biggest major effect concurring to the community is the sightseers beside businesses. the percentage of sightseers suggests the town is favored by recreation travelers, possibly due to attractions like shorelines, verifiable destinations, and common ponders. as tagalag fishing village develops into a key tourism hub for valenzuela city, it brings significant opportunities for local economic growth, particularly through tourism-related activities such as recreational fishing, biking, and nature-based attractions. according to local experts, tourism is seen as a viable economic activity for tagalag, as other industries, such as manufacturing, may not align with the area’s resources and natural features. the challenges of plastic waste and pollution are relevant to the development of tagalag fishing village as an emerging eco-tourism destination. as valenzuela city, including barangay tagalag, continues to explore tourism as a means of economic development, addressing environmental concerns like plastic waste becomes critical. tagalag fishing village, known for its natural beauty and potential for tourism, could face similar challenges with plastic pollution, especially with increased tourist traffic and local commercial activities. while valenzuela itself is not typically called "plastic city," like many urban areas, it does struggle with waste global sustainability research global scientific research 42 management, including plastics. as tagalag fishing village attracts more visitors, particularly for its eco-tourism activities such as fishing, biking, and bird watching, the risk of increased plastic waste could harm the environment, especially if tourism activities outpace waste management capabilities. this environmental impact could undermine the village's sustainability goals, affecting not only the local ecosystem but also the tourism experience. the village’s beautiful coastline and rich natural environment make it an attractive destination for visitors, and the opening of tagalag to tourism has contributed to both business opportunities and increased livelihoods for local residents. however, with this growth in tourism comes the challenge of managing environmental sustainability, particularly with the risks of plastic waste and pollution. as more visitors are drawn to the area, the increase in human activity could exacerbate pollution issues, especially if waste management systems are not adequately scaled to meet the growing demands. just as other urbanized areas like valenzuela city struggle with plastic waste, tagalag could face similar environmental concerns if pollution is not properly addressed. in order to sustain the long-term viability of tourism in tagalag, it is essential to integrate waste management practices that emphasize reducing plastic waste, promoting recycling, and encouraging responsible tourism behavior. these steps will help safeguard the environment, ensuring that the tourism benefits are not overshadowed by negative environmental impacts, ultimately supporting both the economic and ecological wellbeing of the community. framework to sustain the livelihood tourism development and economic prosperity programs of the local government barangay tagalag, situated in valenzuela city, has experienced a notable surge in tourist influx over recent years, predominantly attributed to its ecotourism allure and cultural richness. this paper examines the key drivers propelling tourism growth, shedding light on the economic impacts. tourism comes with tourists and each tourist comes from different places. tourist-generated trash poses a significant environmental challenge in popular destinations worldwide. as tourists explore natural and cultural sites, they often generate considerable waste, including plastic bottles, packaging, and other disposables. improper disposal and inadequate waste management in tourist areas can lead to several adverse effects on the environment and the community such as pollution, health risks to the community, and contamination. with numerous businesses expanding within the barangay, touristgenerated trash and general waste will increase in this small barangay. environment-based tourism should also focus on generating funds to innovate, improve and sustain the beauty of nature by having enough staff and funds. the ordinances and resolutions that are presented and implemented in barangay tagalag are more focused on building infrastructure, business, and livelihood for the community. this recommendation will enhance the environmental element of the barangay tagalag to sustain and innovate its natural resources. to effectively address the challenges of sustainable tourism development in tagalag fishing village, several key actions must be taken to ensure both environmental preservation and community growth. strengthening waste management and pollution control is essential to maintaining the area’s natural beauty. this can be achieved by establishing designated waste collection points, enforcing a zero-waste policy for businesses, and implementing waste management surcharges to fund ongoing cleanup efforts and educational campaigns. another critical step is encouraging sustainable business practices within the local tourism industry. streamlining business permits for eco-friendly enterprises and offering financial incentives for green initiatives will not only attract responsible investments but also promote eco-tourism packages that educate visitors about sustainability. in addition, creating and enforcing comprehensive environmental legislation is crucial for managing development while preserving the village’s ecological and cultural integrity. amending ordinances to mandate design standards and development regulations, alongside the establishment of a monitoring committee, will help ensure that growth global sustainability research global scientific research 43 does not come at the expense of the environment. promoting community involvement is equally important, as engaging local residents in the tourism sector ensures that development aligns with their values and needs. establishing community-based tourism boards and offering incentives for local environmental initiatives can empower residents to take an active role in preserving their heritage and natural resources. moreover, diversifying and enhancing local tourism offerings will help create new attractions and provide tourists with unique, educational experiences. by investing in eco-friendly infrastructure and expanding eco-tourism options, tagalag can generate additional revenue while protecting its natural assets. lastly, ensuring long-term financial sustainability through the creation of an ecotourism development fund and exploring diverse funding sources will provide a stable financial base to support conservation efforts and tourism-related projects. by integrating these strategies into the development plans, tagalag fishing village can strike a balance between promoting tourism, protecting the environment, and enhancing the livelihoods of its residents. this policy recommendation will not only generate funds from the tourists but will also discourage the tourists as well as the people in the community not participating in any littering. environmental responsibility within barangay tagalag's tagalag fishing village, any individual, regardless of residency status, found engaging in littering or improper trash disposal shall receive a fine of php 200.00. for other offenses committed within a period of one year, the penalty is php 500.00 for second offense, php 1,000.00 for third and php 2,000.00 for fourth. this law in tagalag fishing village is maintained by designated workers and members of the barangay who are to ensure that it happens. in tagalag fishing village this legislation is enforced by barangay officials and assigned personnel whose duty is to supervise its implementation. such a low occurrence is maintained by the residents and tourists being asked in this way to report such acts which include throwing rubbish into the river or any other form of inappropriate garbage disposal to their barangay officials. all cases of offenses, notices given and fines paid are checked by the committee that employs a comprehensive reporting system under barangay tagalag cleanliness and sustainable living committee. environmental projects in the barangay such as cleanliness campaigns will be supported using fines collected from sustainable living initiatives among others that demonstrate proactive commitment towards reducing negative implications of poor garbage management on community development and fostering community development within tagalag fishing village. besides, each environmental revenue source will incur a p50.00 environmental fee as part of barangay tagalag’s comprehensive environmental management plan for the tagalag fishing village. this is applicable to both tourists and residents engaging in fishing, boating or having floating bars or restaurant structures; the aim is to have this fee used directly in conservation and improvement projects in the locality’s sustenance. the proceeds from these charges are utilized to fund specific development projects that fit together with what barangay tagalag stands for regarding nurturing their natural resources and promoting sustainable growth as well. such an approach promotes responsible conduct while at the same time laying a financial foundation that can cater for ongoing environmental interventions within its larger community due to all these activities. it is a global growth trend but full of contradictions. in nature-based environments, there is an exponentially growing problem of tourist waste. the unwto notes that cases can be made for the increasing number of tourists globally as indicators of rapidly growing waste issues. for instance, potential case studies on renowned ecological tourist spots have unveiled some shocking figures which explain why they must be attended to urgently. this trash causes visual pollution, mars natural scenery and disrupts ecosystems thereby leading to loss of habitats for wildlife and fragile ecosystems. in environmental science journals and waste management researches however, plastic wastages stand out as one of the most extensively studied culprits exhibiting its wide proliferation and harmful impacts. environmental fees play vital roles in sustaining community viability alongside guiding tourism enhancement. such fees provide essential financial support for environmental activities such as garbage disposal, conservation of habitat hence safeguarding local natural assets promoting green tourism among other environment lovers global sustainability research global scientific research 44 within that community. in addition, the thoughtful application of these levies facilitates the invention of environmentally friendly infrastructure and the adoption of sustainable tourism practices. environmental fees become important instruments in ensuring that towns may profit economically from tourism while maintaining their natural integrity over time. this is achieved by finding a balance between ecological preservation and economic growth. the primary objectives of the policy recommendation are not to help the community's growth in the economy and sustain the livelihood, the local government should first improve the environment, nature, and natural resources of barangay tagalag. currently, tagalag fishing village is generating tourists and income through how tourists explore the place but no assurance that the tourists will keep on coming. trash and waste is also generated by tourists and as soon as possible the community and the local government unit should reduce the future risk. trash and waste will tarnish and destroy the natural resources that the tagalog fishing village has today. generating funds via littering or garbage violations and environmental fees will also generate or develop infrastructure that can be another tourist spot. this will help the livelihood of the community and will attract more tourists. environmental funds can be also used for the maintenance of the current tagalag fishing village to retain its beauty and natural resources. the people of the community will be the first ones to benefit from this policy recommendation. cleanliness is crucial for both the community and tourists in an ecotourism zone. this maintains the original environment and is responsible for local ecosystems being well and ensuring better tourist experience of unaltered beauty. moreover, a clean environment in any society leads to healthier livelihoods, cultural preservation, and good living conditions. additionally, cleaning provides an educational platform where people are aware on how to conserve their environments. lastly, a clean ecotourism area guarantees the existence of natural resources hence helping the community as a whole and making it possible for tourists to enjoy themselves. the fee of the environment holds a paramount importance for businesses and income generating activities in a tourism spot or eco-tourism zone that use tagalag fishing village’s natural resources. this promotes sustainable development directly, which helps businesses operate in an ecologically friendly way to secure the future of the place. it also leads to improvement of infrastructure and facilities making it more attractive to tourists. in addition, the fee attracts visitors who are responsible and concerned with conserving environments thus increasing business’ attractiveness. these funds help in upholding natural attractions hence ensuring that these businesses have positive images and reputations. by creating community engagement and establishing financial self-sufficiency measures, environmental fees are very essential in ensuring that businesses not only thrive but also coexist harmoniously with their surroundings. conclusion the study concluded that the local government measures sustaining the development of sustainable livelihood tourism in tagalag fishing village, in 2016, barangay tagalag declared as an ecotourism zone while the city of valenzuela implemented laws and policy that regulates the improvement and preservation of the environment of tagalag. the development and maintenance are empowered as well as the imposition of administrative penalty by ordinance 309. in addition, the ordinance 547 series of 2019 grants protection and incentives to anyone who will be affected by the development and construction of tagalag fishing village, specifically the boardwalk project. amidst covid-19 in 2021, the local government of valenzuela city amended the city ordinance no. 630 from 2019 due to the effects of covid-19. this ordinance modifies ordinance no. 630 from 2019, also known as the “tagalag fishing village ordinance.” it extends tax incentives to individuals, businesses, or corporations that establish or operate new tourism-related businesses in barangay tagalag, aiming to promote the tagalag fishing village. in examining the role of tourism in the economic development of barangay tagalag, global sustainability research global scientific research 45 it becomes clear that fostering economic activity is crucial to the area’s growth and sustainability. as highlighted in the interview with a local government official, “economic development depends on the economic activity in an area. when there is economic activity, it means people are earning, and when people earn, the government collects revenue through taxes. if there is no way for people to earn, they will leave. therefore, the government plays a key role in facilitating economic activities, such as businesses, so that development can continue.” this perspective underscores the importance of a structured approach to developing tourism-related businesses, which not only attracts visitors but also supports local livelihoods, generates income, and contributes to the overall economic vitality of barangay tagalag. as tagalag fishing village continues to grow as an ecotourism destination, it is essential that the local government facilitates economic activities that align with both the community’s resources and the region’s tourism potential. the introduction of policies, such as tax incentives and environmental fees, ensures a sustainable approach to tourism that benefits the local economy, preserves cultural heritage, and maintains the environmental integrity of the area. by encouraging local businesses, such as restaurants and souvenir shops, to flourish, the community can create more job opportunities, increase government revenue, and contribute to the long-term success of the region. ultimately, the success of tourism in tagalag hinges not only on attracting visitors but also on cultivating a thriving local economy that supports sustainable practices and creates lasting benefits for the residents. by continuing to prioritize economic development alongside environmental and cultural preservation, barangay tagalag can ensure that the positive changes seen in recent years are not just short-term improvements, but the foundation for a vibrant, sustainable future. the information given here exhibited the significant input of tagalag fishing village project in improving the socioeconomic status of barangay tagalag. the findings indicated that livelihoods, youth education and economic security have been enormously improved making it possible for them to live a decent life. its success was underscored by the fact that most respondents agreed on its effectiveness in creating more employment opportunities, boosting the growth of businesses and enhancing the local economy. besides, satisfaction among inhabitants; with government and community support brings about tourist attraction and new opportunities which demonstrate how successful this project has been at meeting residents’ needs as well as wants for barangay tagalag. a respondent stated that “the business is growing from the tourist, therefore there are more income” which was similar to most population of the respondents. tagalag generated livelihood and helped grow the local small and medium business along the area. another indication that this project has multiple benefits can be seen through tricycle operators and drivers association’s (toda) implementation of local tourism which is not only contributing positively to the community's economy but also generating income for its society. this case study on development of a fisheries village demonstrated what can be achieved by pooling resources together between government departments, relevant stakeholders at local levels and community members. this showed the power of targeted activities to improve socio-economic conditions and the quality of life of people and families in rural areas. based on the results of this study, the researchers developed a framework that implies enhancing the environmental features of barangay tagalag in order to preserve and innovate its natural resources. the policy recommendation will not only generate funds from the tourists but will also discourage the tourists as well as the people in the community not participating in any littering. recommendation the researchers recommended the following actions be taken in order to maintain the ecotourism zone of barangay tagalag, fishing village, based on the previously described findings and conclusion. for the city tourism of valenzuela, to monitor the tagalag fishing village on serving good customer service for the tourists that are entering and exiting the barangay tagalag fishing village, as well as to ensure the natural resources of global sustainability research global scientific research 46 the tagalag fishing village. the local community can actively contribute to the development of sustainable livelihood tourism by taking part in tourism-related activities like homestays, tour guiding, and handicraft making. the barangay tagalag is accountable for ensuring the safety of visitors and the residents of tagalag fishing village. also, communities can also promote the conservation of natural resources in the area. the local government of valenzuela plays a crucial role in promoting sustainable livelihood tourism development by providing infrastructure, facilities, and services that attract visitors. as such, they have the ability to formulate regulations that both guarantee the conservation of their interests and encourage local community involvement in the tourism sector. future research should explore the long-term socio-economic and environmental impacts of ecotourism in barangay tagalag, particularly focusing on the sustainability of local businesses and natural resources. future research should evaluate the effectiveness of existing policies and regulations in promoting sustainable practices and mitigating the negative effects of increased tourism. a closer look at the engagement of the local community in these initiatives could also provide insights into strengthening their role in preserving tagalag's cultural and natural heritage. future research should focus on the long-term sustainability of ecotourism in barangay tagalag, examining both its economic and environmental impacts. studies could assess the effectiveness of policies promoting sustainable practices like waste management, resource conservation, and community participation. given that tagalag fishing village is still in its early stages, research should also monitor the development of infrastructure, local businesses, and the preservation of natural resources to ensure they can thrive without compromising ecological balance. ongoing research will be crucial in identifying challenges and opportunities as the village grows, ensuring its sustainability as a destination for future generations. declaration acknowledgment: n/a funding: n/a conflict of

ecotourism; livelihood; local communities. introduction the profile of ecotourism as a conservation and development strategy over the last few years has been on the increase. it provides scope for non-consumptive use of natural resources by involving the people living in and around natural areas. the governments of many developing countries, richly endowed with natural resources, consider ecotourism as a strategy of generating foreign exchange to boost their economies (schevynes, 2002). far from altruistic sentiments, many tourism operators and companies label their operations as ecotourism just to get a share of the burgeoning market phenomenon referred to as ‘green-washing’ (wood, 2002). the unprecedented growth of conventional mass tourism and the considerable negative impacts it has caused in many destination countries have led to the canvassing of alternative forms of tourism that have fewer impacts on the global sustainability research global scientific research 30 environment (eber, 1992). ecotourism is considered a befitting alternative to conventional mass tourism, a means of turning remote regions rich in natural resources into a ‘viable productive bases’ and a tool for achieving sustainable development (barkin, 1996). it is expected to help in improving environmental awareness as well as means of fostering global co-operation. the ecotourism activity must be environment-friendly, socially acceptable, and economically viable for sustainability to be guaranteed. it tends to shift emphasis from preservation to conservation and from consumptive use to non-consumptive exploitation (munt and mowforth, 1998). it should generate enough income to make people value their resources, and from the visitors’ perspective, it should sustain their interests by offering a rewarding and fulfilling experience. local people should be involved in planning, control, and management activities of ecotourism. these activities should be substantial enough to complement their livelihood options and constitute an incentive to value natural resources. ecotourism has been viewed not only as a development strategy but also as a tool of poverty eradication in many countries in the world. this is because of its perceived benefits in the areas of employment, the balance of payments, regional development, and foreign exchange earnings (hall, 1994). the quebec summit declaration in 1992 recognized ecotourism as a vehicle of economic development, especially in the least developed countries (ldcs) (fennell, 2003). moreover, ecotourism is one of the few strategies for economic diversification because it capitalizes on the assets available to the poor, such as their cultural and natural heritage. it also provides small-scale labor opportunities better than all other economic sectors apart from agriculture (wto, 2002). local people could participate in providing goods and services to tourists in ecotourism sites. they need minimum skills, little capital, minimum special technical expertise, and foreign language proficiency in this regard (ashley and carney, 1999). women, for example, can engage in the sale of souvenirs such as handicrafts or serve as food vendors (goodwin, 1996). women engage in the sale of fuelwood and vegetables to campers in namibia (scheyvens, 2002). ecotourism maintains close interaction between tourists and locals over a long period in a small area. ecotourism has been seen not only as a conservation strategy but also as a way of making the concept of sustainable development operational. these benefits can attract economic value to the environment and thus give an incentive to conservation (butler, 2000). the asean countries are giving priority to ecotourism development in this region to enhance the local community’s empowerment and benefit-gathering. ecotourism development is able to ensure conservation of natural resources, environmental well-being, and sustainable development in the local areas in a meaningful manner (dowling and weiler, 1997). teh and cabanban (2007) identified some strategies to develop ecotourism in the marine sites. the strategies are conserving marine diversity, reducing misuse of natural resources, and ensuring the support of local communities to maintain the resources. they suggest these strategies through their study on pulau banggi of sabah in malaysia. yusof and rahman (2011) recommended several guidelines to increase the satisfaction of tourists towards ecotourism activities in a site. the guidelines are reusing and recycling the resources, conservation of natural resources, integrated approaches with the communities to develop the environment, and exchanging opportunities for local culture. bhuiyan et al. (2012) identified that local communities supported ecotourism activities for their well-being. their study on sekayu recreational forest in malaysia shows that ecotourism provides positive impacts on the local environment and the livelihood of communities. through a study on a national park in vietnam, luong (2024) emphasizes biosphere values, environmental beliefs, and environmental well-being of the tourism stakeholders to ensure successful ecotourism development in an area. subongkoda et al. (2025) highlighted that a balanced combination between community participation, tourism components, and environmental factors is essential for ecotourism development. the researchers identified that tourism components and environmental factors have a significant relationship with the community participation for ecotourism development through a study on the community leaders in thailand. global sustainability research global scientific research 31 the challenges of ecotourism development are maintaining environmental quality, preserving the natural resources, ensuring tourists’ satisfaction, and providing benefits for the local communities to improve their livelihood. excessive uses of natural resources due to ecotourism development reduce the quality of recreational activities in ecotourism sites. yacob et al. (2009) revealed that some ecotourism activities, such as snorkeling and scuba diving, create negative effects on natural resources. their study on marine parks in malaysia suggested that increasing awareness, conservation of marine resources, park management, and benefit sharing with the local communities are necessary for ecotourism development in the marine parks. jaafar and maideen (2012) revealed that ecotourism sites face difficulties in maintaining a balance between the environment and tourism activities due to excessive use of natural resources. their study on timon and redang island in malaysia suggested that conservation of marine resources and environmental awareness help to maintain sustainability in ecotourism sites. several studies (teh and cabanban, 2007; yacob et al., 2009; yusof and rahman, 2011; bhuiyan et al., 2012) show that local communities provide their support and positive efforts towards the ecotourism development in any sites to ensure well-being for their livelihood. ross and wall (1999) identified through their study on north sulawasi. indonesia that locals are willing to play a role in natural resource protection, and ensure positive impacts from ecotourism activities for long-term viability. ni’am et al. (2021) emphasized the importance of nature conservation for market-oriented ecotourism expansion from the context of the community perspective. the study highlighted the self-managed, experienced, and benefit-sharing role of local communities for reducing conflict with wildlife and natural resources through ecotourism activities. thys et al. (2016) highlighted on effective conservation and management of ecotourism resources through the behavioral intention of local communities to satisfy the tourists. central buton island is located in south-east sulawesi in indonesia. the island was the most important precolonial kingdom of south-east sulawesi, with its old headquarters in wolio. the island received the backing of the dutch against makassar and temete in the 17th century and later came under direct dutch control. the island was given limited autonomy in 1906 by the dutch colonialists. the two rainforest reserves located in the region offer a rich natural setting under a favorable political atmosphere. the forests of central buton are categorized into three: national reserves (which include the lambusango and kakenauwe nature reserves), protected area forests, and limited production forests. the lambusango and kakenauwe nature reserves jointly cover an area of 25,163 hectares, and they are controlled by the provincial conservation agency. their reserve status is backed by the national legislation because of their biological significance. about 1.7 million hectares of forest are converted to different uses every year, and 20% of the forests of south sulawesi have been lost in the same period (malleson, 2005). the major threats to these reserves are selective logging, illegal hunting for meat and trade, pet trades on monkeys and birds, and conversion of forestlands for agricultural production. consequently, the management scheme was built on community participation in managing the district-controlled forests via granting village contracts in return for conservation. ecotourism could be an alternative or complementary strategy to the village contract by virtue of the fact that it involves a non-consumptive and nonextractive pattern of utilizing resources. the present study identifies the ecotourism development impacts on the livelihood of local communities. materials and methods methods the study was conducted at labundo-bundo (opwall’s forest base) in central buton island, south-east sulawesi. both quantitative and qualitative methods were used for data collection in this study in order to obtain factual information about the actual benefits of ecotourism to livelihood and to understand the social global sustainability research global scientific research 32 circumstances in the study areas. the quantitative techniques of structured questions in the survey were further completed by qualitative interviews that were conducted at some selected households that the researchers considered important in the communities. quantitative techniques try to find out factual evidence deemed relevant to get the information required. qualitative techniques, on the other hand, are carried out to understand some specific social phenomena (devaus, 2002). household survey the household survey has been used in this study to collect primary data from the respondents. household surveys are useful in facilitating the investigation of the range of assets and capital as well as livelihood options available to households, especially in developing countries. it also allows the acquisition of a large volume of information about a given population within a very short period of time (yansaneh, 2003). profile of villagers the villages were selected because of their proximity to the two forest reserves of lambusango and kakenauwe (figure 1). the selection was also done to enable the comparison of the effects of ecotourism on the livelihood of local communities. the selection is also expected to enable the investigation of changes in the attitude and behavior of local people to ecotourism based on the degree of exposure. the total population of labundo, waoleona, wakangka, and lawele is 408, 915, 1220, and 3050, respectively. most of the villagers in labundo, wakangka, and lawele are farmers (>80%) and fishermen (>60%) in waoleona. figure 1: map of buton island global sustainability research global scientific research 33 sampling and questionnaire the goal of any sampling strategy in the quantitative survey is to get a representative sample, which can capture the general characteristics of the population (devaus, 2002). efforts were made to ensure all the occupational groups, genders, and age categories were interviewed. to ensure this, the respondents were not only interviewed in their homes but also in their firms, workshops, and schools. the qualitative sampling was done on the basis of the appropriateness of the respondents in providing the required information, as well as their access to the information required. random probability sampling was used in the household survey because of its simplicity and the fact that the population is concentrated in a given geographical area. the limited variation and number of the population and time constraint informed the choice of the sample size. the survey was carried out in four villages, namely: labundo-bundo, waoleona, wakangka(wapancana), and lawele. these villages are famous as ecotourism attractions due to their suitability for expanding tourist activities as well as ensuring benefits for locals. moreover, environmentally friendly situations of these four villages are helpful to reduce the negative impacts of tourist activities. a total of 160 households were surveyed (forty from each of the four villages). the questionnaire consists of 47 questions in four sections. these questions are structured to elicit information on the general demographic profile, means of livelihood, tourism knowledge, and environmental knowledge. results and discussion most of the respondents interviewed are male (60%), the majority are married (83.8%), and the average age is 40 years. both husbands and wives jointly contribute to family income in 73.1% of cases in all the villages. most of the respondents are self-employed (78.8%), predominantly engaged in farming occupations (57.5%). although there is an array of occupations in the study area, many respondents said they do not have any alternative occupation (51.3%). more than half of the households in all villages except lawele do not have distant relatives to support them in case of need. however, people rely on close families and neighbors (68.8%) for supporting some work as casual laborers on farms (8.1%), yet others seek government loans (7.5%) at a small interest rate. the majority of respondents in labundo (60%) consider themselves powerless in case of economic shocks, and only 20% of them feel secure. the people of lawele feel more secure in economic crises than all other villages, with 45% of respondents, while 52.5% of the households in wakangka are comfortable. it is surprising that despite additional sources of income through ecotourism in labundo, the people feel powerless economically. this means, despite a need for an alternative livelihood strategy, ecotourism may not be sufficient in fulfilling the economic needs of the people, but could be a good complement. table 1 below summarizes the major problems facing the four villages based on the responses of respondents. lack of access to credit facilities to expand the farming operation and or to start a trading business appears to be the most pressing concern of households in the four villages. although poverty was not considered to be a major problem, however, unemployment has been identified as a serious community problem in all the villages. this result demonstrates a lack of government intervention in many facets of people’s lives. although it will be difficult for any ecotourism project to make a serious impact on all the problems identified above, however, through properly planned community development activities, the severity of the problems can be minimized. ecotourism activities are taking place only in labundo village at the moment. however, respondents in all the villages covered by this study expressed their opinions and expectations about coming to the area. some of the good things the locals like about ecotourists include their ability to adapt and interact with the locals, their personalities and polite nature, language, their help with conservation, and making the community popular. however, there are a lot of negative feelings towards the tourists as well. although 51.3% of the respondents global sustainability research global scientific research 34 refused to make any comments, a lot of them find visitors’ lifestyles and the seasonal nature of their visits objectionable. table 1: community problems in the study area community problems labundo waoleona wakangka lawele lack of credit 5 11 13 14 health 1 4 1 0 roads 17 0 1 0 unemployment 15 9 6 17 poverty

ecotourism to the community, to the family, and at present levels. the results revealed interesting answers that could be useful for planners of an ecotourism project in the region. at the community level, the residents expect tourists to help them with their core occupationsfarming and fishing by providing them with equipment (51.3%). they also want visitors to give them credit (14.4%), provide them with education (25.6%), medical assistance (4.4%), and sports (3.8%). this is a high level of expectation and further demonstrates the absence of government interventions in addressing the pressing needs of the communities in the study area. the respondents were asked how they would help visitors coming to their area, and 40.6% said they would strive to satisfy their needs. a good number (34.4%) would be hospitable, and yet many others (8.8%) would guarantee their security. based on hospitality, it would be safe to generalize that all the communities would treat their visitors very well. the enthusiasm and euphoria accompanying volunteers’ visits to neighboring villages are very noticeable. household average monthly income was used as a measure of economic benefits instead of household expenditure. the average monthly income of the people of labundo and waleona was rp 376,666.67 and rp 360,256.41, respectively. lawele had the highest income of rp 501,351.34, followed by wakangka with rp 401,714.29. this result reveals that despite five years of ecotourism operation in the village of labundo, the income level of the villagers is not greater than some of the neighboring villages. this could be attributed to the livelihood options available in lawele and wakangka, which are greater than in labundo and waleona. the residents of lawele and wakangka have the opportunities of engaging in paddy cultivation a well as fishing; a lot of civil servants are living there also. on the other hand, the people of labundo rely on farming only, and those in waleona on fishing. the slight differences between the last two could be attributed to opportunities provided by ecotourism operations taking place in labundo. based on this, therefore, the contribution of ecotourism to household incomes in the region could be said to be insufficient. this finding is similar to that of bookbinder et al. (1998) in nepal. the results show that not all the villagers are satisfied with their income levels, with labundo residents surprisingly requiring the highest monthly income (rp. 1,161,538.46). it is not known whether this has anything to do with changing tastes and lifestyles as a result of ecotourism operations in the village (figure 2). global sustainability research global scientific research 35 figure 2: household average monthly income of study areas the income from ecotourism and other occupations was compared in labundo to ascertain the extent to which ecotourism activities constitute viable livelihood options. the results show that only civil servants, like teachers and pensioners, earn higher incomes than ecotourism-related jobs. the average monthly income of a civil servant is rp. 1 million, for instance, and a tour guide earns rp. 0.9 million and a porter rp. 0.48 million. traditional occupations like farming and fishing earn only an average of rp. 0.3 million a month (figure 3). figure 3: income from the occupations this result demonstrates that ecotourism jobs generate more income than traditional occupations in the region. a lot has been said about the seasonal and, therefore, unstable nature of incomes from ecotourism, a situation that has led to widespread anxiety about relying on it as a sustainable economic development strategy. however, the fact that most of the livelihood options available to local people are equally seasonal in nature, a lot of them global sustainability research global scientific research 36 even more variable than ecotourism, has been largely ignored. to buttress this point, cashew, for example, is harvested only once a year and earns only a paltry rp. 241,600, on average, to the farmer. on the other hand, a guide earns rp. 900,000 every month out of the three months ecotourism operates in the region, meaning that a guide earns rp. 2.7 million in a year (figure 3). information gathered through interviews revealed that the ecotourism project supports about 94 jobs in the labundo base alone. out of these, 44 are temporary and 50 are permanent. unlike many ecotourism projects in other parts of the world, where the number of jobs for outsiders is greater than for locals, the reverse is the case in labundo, as 73 jobs out of 94 go to the residents, and outsiders hold only 21 jobs. there are a number of indirect employment opportunities as well as in the areas of accommodation, transport, and security services. about 25 households out of 51 rent out part of their homes to volunteers during the ecotourism season. households earn rp. 30,000 per night, and most houses host up to four volunteers at any given time. this constitutes a viable source of income to a very remote rural area that is far away from government attention. many households that own ‘microlite’ buses also earn significant income from vehicle charter. the vehicles are chartered at rp. 50,000 to 100,000 a day. many residents also benefit by working as security personnel to ensure the safety of volunteers. other indirect economic benefits include increased profits to traders and foodstuff sellers in labundo village during the ecotourism season. this result indicates that if ecotourism could be extended to the other villages, it could reduce unemployment significantly. considering the fact that the threat to the natural resources in the area is partly caused by unemployment, a successful community-based ecotourism project could minimize the level of threat (figure 4). figure 4: average earnings from common crops and tourism jobs the comparison of earnings from tourism activities and traditional jobs of study areas revealed that ecotourism is suitable and offers potential income opportunities for the local communities due to high outcomes as well as a sustainable livelihood option. a lot of community development efforts were conducted in labundo over the last five years. although most of these interventions are executed occasionally, nevertheless, they help the residents significantly. some of the community development efforts executed by the tour operator include the donation of building materials such as cement, school supplies, and sports equipment. significant community assistance is of free medical services in global sustainability research global scientific research 37 the area. this medical service extends to the neighboring villages as well. there are a number of tangible conservation benefits occurring in the region from existing activities. the entrance fees paid yearly to the two forest reserves (lambusango and kakenauwe) help the conservation agency (ksda) to carry out its duties more effectively and also give economic value to the reserves. ksda rangers are also supported financially to improve their surveillance of protected areas. other benefits include conservation awareness to local schools through quiz competitions and the production of posters and pamphlets. a number of benefits of ecotourism to the region are intangible but substantial. this is reflected in the pride exhibited by residents of labundo. although, difficult to gauge but it has been observed that many people of labundo are proud of their english language skills. in the area of sports, a combined residents-volunteers team is normally formed to engage teams from other villages. this further gives the local people a tremendous sense of pride. community cohesion is also improved remarkably as the residents cooperate to make the volunteers feel safe and comfortable. the sense of pride can, therefore, be enormous in a situation where the communities themselves host the project. residents of waoleona, wakangka, and lawele are always eager to host visitors just like the people in labundo. improved community cohesion can nurture an atmosphere of mutual support and reduce intra-village and inter-village conflicts. conclusion and recommendations this study has shown that ecotourism can contribute to people’s livelihoods by providing an array of economic benefits through income and employment. ecotourism operations are making a significant impact on people’s livelihoods. this is because the people in the village have few options to diversify, and the majority of them consider their families powerless in case of economic shocks. the low household income in labundo, even with the significant injection of tourism funds into the village, indicates how vulnerable the village will be without ecotourism. this study has established that people in labundo rely on incomes from ecotourism for the satisfaction of two important household needs: feeding and housing. findings from this study show that the average income households generate from renting their houses amounts to rp. 900,000 per month. this study, therefore, has established that, unlike general beliefs, ecotourism jobs are more rewarding and stable than most of the existing livelihood options in the area. other benefits resulting from ecotourism include community development interventions such as medical services, infrastructure building, and education, enhancement of community pride and cohesion, and cultural exchanges between visitors and residents. ecotourism operations in the area have also achieved remarkable success due to natural resource conservation. these achievements include the discovery and naming of numerous species in science, exposing the scientific value of the forest in the regions, attracting global funding, and drawing the attention of the central government to the area. environmental awareness among the villagers has also been improved as a result of activities such as school quizzes, publications, and conservation education efforts. there are also no indicators to gauge whether current practices are not causing negative consequences to the environmental and social fabrics. despite the existence of rules to guide the behavior of visitors, some violations were observed, and these are exacerbated by the failure of the villagers to create awareness among the tourists about the importance of respecting their traditional norms and values. the scope of ecotourism in improving the livelihood of people in the study area, it is important to plan and manage ecotourism projects effectively. the necessary recommendations in this regard are as follows; community-based ecotourism: a new community-based ecotourism project could be integrated into the lambusago forest management project, which can provide scope for the local communities to be involved in forest protection. ecotourism could complement the village contract and licensing strategies designed to allow global sustainability research global scientific research 38 communities surrounding the production forest area to benefit economically by allowing them sustainable exploitation of the forest resources. training: the tourism department should provide the training required and activate the numerous plans and strategies it has for the development of the sector, such as marketing, monitoring, and regulation. government involvement: the local people may not have sufficient skills and knowledge. this means that they could do little to guide the activities sustainably. the forest departments and other government organizations should be involved, therefore in setting up indicators and guidelines for the nature-based activities to be conducted under ecotourism development. they should also be the monitors and enforcers of conservation rules in the ecotourism development process. declaration acknowledgment: n/a funding: the authors have no financial interests to disclose. conflict of interest: the authors have no conflict of interests. ethics

remote sensing; agri-spatial; decision making; policy integration; sustainable agriculture introduction the global demand for food has experienced a significant growth and is projected to further climb by 59-98% by the year 2050, as stated by elferink and schierhorn (2016). nevertheless, there is a mounting apprehension regarding the inability of agricultural food production systems to meet the substantial demand, particularly in impoverished nations, hence exacerbating the issue of food insecurity (bjornlund et al., 2022; akter et al., 2023; raihan, 2023a). the presence of inefficiencies within food production systems has been identified as a contributing factor to the issue of food insecurity (ali et al., 2022; viana et al., 2022; raihan, 2023b). effectively promoting enhanced food production while ensuring the preservation of land and water resources, energy sustainability, and environmental integrity poses a significant challenge that necessitates attention from governmental bodies and policymakers (brgum et al., 2020; zhang et al., 2023; raihan, 2023c). global sustainability research global scientific research 2 in numerous lowand middle-income countries (lmics), the primary source of food production is predominantly situated in rural areas, where smallholder and subsistence farmers play a dominant role (moustier et al., 2023; raihan, 2024a). in order to promote the sustainability of smallholder farmers, it is crucial to empower them with practical knowledge (raihan et al., 2022a; ghosh et al., 2023). this information should help farmers to make decisions based on evidence and effectively execute strategies that can enhance their farm productivity and overall sustainability (raihan et al., 2022b). in order to address the limitations of traditional subsistence production practices, it is imperative to adopt sustainable production approaches that promote efficiency and improved agronomic practices (raihan et al., 2022c). the strategies encompassed in this approach consist of the cultivation of crops that are resilient to climate conditions, the utilization of crop types that have high yields, the implementation of methods for predicting crop yields, the adoption of integrated pest management techniques, and the incorporation of biodiversity solutions into sustainable food production systems (giri, 2023; raihan et al., 2023a). in order to implement these innovative interventions effectively, it is imperative to possess complete and current datasets encompassing both spatial and non-spatial information. additionally, the utilization of advanced gis technologies capable of amalgamating and synthesizing various types of data, such as spatial, social, demographic, economic, and environmental, is crucial (kross et al., 2022; raihan et al., 2023b). the synthesis process would yield geographical knowledge that is grounded in evidence, so enhancing our comprehension of agricultural sustainability and facilitating more effective policymaking and decision-making endeavors (raihan et al., 2023c). the current advancements in gis, rs, and geographic positioning systems (gps) technology offer a potential avenue for obtaining and implementing highresolution satellite imagery and digital spatial data (trivedi et al., 2022; raihan, 2023d). spatial data in the field of agriculture have been essential in examining the spatial connections between social, physical, agroecological, and environmental factors, and their impact on the sustainability of agricultural practices (raihan et al., 2023d). the utilization of gis technology offers users a comprehensive array of tools and methodologies for managing geospatial information. this technology enables users to gather, store, merge, interrogate, present, and examine geospatial data across different levels of detail (avanidou et al., 2023; raihan & tuspekova, 2022a). remote sensing technology is utilized to obtain images and gather various data pertaining to crops and soil. this is achieved through the utilization of sensors that are installed on diverse platforms such as satellites, airborne remote sensing devices (including manned drones and unmanned aerial vehicles), as well as ground-based equipment. subsequently, these acquired data are processed by computers to support agricultural decision-making systems (awais et al., 2022; raihan & tuspekova, 2022b; huang et al., 2023). the examination of agriculture's geographical context can be approached by considering the varying levels of access that farmers have to livelihood capitals, local resources, and critical infrastructure and services within a certain geographic area (wang et al., 2023; raihan & tuspekova, 2022c). the deconstruction of data encompassing many aspects inside a gis can be achieved through the organization of nested spatial layers. these layers are established based on local geography, with geographic coordinates obtained through the utilization of gps technology (raihan & tuspekova, 2022d; warren et al., 2023). the geographical layers can be further subjected to processing and analysis inside a gis platform, enabling the exploration of various aspects such as crop and soil conditions, spatial relationships, crop trend prediction, land-use change monitoring, pest surveillance, and biodiversity protection (raihan & tuspekova, 2022e; taiwo et al., 2023). furthermore, these tools can also be employed to effectively delineate and expose spatial barriers that hinder agricultural productivity, or even generate novel insights to enhance agricultural sustainability (raihan & tuspekova, 2022f). in contemporary times, policymakers have shown a growing interest in exploring the potential of advanced gis, rs, and gps technologies to enhance agricultural productivity and optimize production practices. this interest stems from the recognition of the escalating intricacy inherent in agricultural production systems (raihan & global sustainability research global scientific research 3 tuspekova, 2022g; yadav et al., 2023). the utilization of gis in the field of agriculture has witnessed a notable rise, leading to enhanced prospects for the establishment of more advanced spatially explicit frameworks. these frameworks serve to facilitate the construction of dynamic agricultural databases and interactive systems (raihan & tuspekova, 2022h; chen et al., 2023). these database systems enable users to engage with farm data that is geographically referenced in real-time, offering accurate positional data and so enhancing decision-making frameworks. emerging applications of gis have been observed in the agricultural sector. the aforementioned areas encompass precision agriculture, crop yield forecasting, automated farm systems, climate change detection, and real-time monitoring of agricultural production (karunathilake et al., 2023; raihan & tuspekova, 2022i; khan et al., 2023). these technologies possess the potential to enhance agricultural productivity and ensure food security. several recent comprehensive literature evaluations have been done to elucidate and consolidate the diverse applications of gis, rs, and gps technologies in the agricultural sector. systematic mapping analysis has been conducted by garcía-berná et al. (2020) to examine the prevailing trajectory and emerging prospects of remote sensing techniques in the field of agriculture. the researchers observed a notable rise in the adoption of rs technologies for the collection and extraction of georeferenced information gathered from imagery from satellites and unmanned aerial vehicles (uavs) in their investigation. spatial data derived from these advanced technologies has been utilized in several domains such as estimating crop growth and production, extracting parameters related to cropland, detecting weeds and diseases, and monitoring the availability of water and nutrients in plants. the authors did not provide an elaboration on how this application could be used to enhance spatialbased agriculture policymaking. moreover, al-ismaili (2021) emphasized the utilization of rs and gis methodologies in the field of precision agriculture. these techniques have proven to be effective in the accurate mapping, identification, and categorization of greenhouses using aerial imagery and satellite data. the potential integration of this technique into the improvement of policymaking was not discussed. weiss et al. (2020) conducted a meta-review that emphasized the growing advancements in rs and its relevance to several domains such as crop breeding, crop yield forecasting, agricultural land use monitoring, and biodiversity loss. sharma et al. (2018) examined the utilization of gis data applications in the advancement of precision agriculture. the proposed framework, referred to as "big gis analytic," was put up by the authors as a means to provide guidance on the appropriate utilization of large-scale gis data within the context of the agriculture supply chain. the framework proposed by the authors establishes a theoretical basis for enhancing the efficacy of gis data utilization in the agricultural sector, with the ultimate goal of increasing productivity. these studies contribute to the comprehension of the advancements in the uses of gis and rs in agricultural production systems. nevertheless, the existing systematic evaluations appear to lack precise information on how gis and rs technologies might effectively promote the integration of the spatial aspect of agriculture into policy frameworks and actions. there is a growing need for evidence-based decision-making to aid policymakers in evaluating the specific requirements of farmers at the local level, enhancing production and supply value chains, and implementing spatially targeted interventions (raihan & tuspekova, 2022j). this study seeks to consolidate current information on the utilization of gis and rs in the agricultural sector. the objective is to explore how these technologies might contribute to evidence-based policymaking for the enhancement of agricultural sustainability. additionally, the review aims to highlight the challenges and barriers that hinder the widespread adoption of gis and rs applications, with a special focus on lmics. the present investigation explored the contemporary and prospective viewpoints regarding the incorporation of gis into policies aimed at promoting agricultural sustainability. the primary contributions of this study are to furnish researchers and policymakers with empirical data about the utilization of gis technology within the agricultural sector. this evidence sheds light on how gis technology has enhanced agricultural production methods and offers insights into its potential adoption for improving evidenceglobal sustainability research global scientific research 4 based decision-making processes and policies. the results of this study could potentially contribute to the formulation of policies that successfully include sustainable and climate-smart agricultural practices. methodology this paper aims to present a concise overview of the utilization of gis and rs techniques in agriculture, with a focus on the most current research findings. the present study employed the systematic literature review methodology as suggested by tawfik et al. (2019). according to benita (2021), the systematic literature review framework is considered to be a dependable approach. a preliminary review of the literature was conducted to identify pertinent articles, validate the proposed idea, avoid redundancy with previously covered issues, and ensure the availability of sufficient articles for conducting a comprehensive analysis of the subject matter. moreover, the focal point of the themes was to explore the application of gis and rs across multiple agricultural segments. according to tawfik et al. (2019), it is crucial to enhance the retrieval of results by acquiring a comprehensive understanding and familiarity with the study topic through the examination of pertinent materials and active engagement in relevant debates. this objective can be achieved by conducting a thorough examination of pertinent literature and actively participating in pertinent academic conversations. an in-depth review was undertaken on a total of 56 scholarly articles obtained from the scopus, web of science, and google scholar databases. the manual search results were initially enhanced and polished through the process of examining the reference lists of the included publications. subsequently, the investigation also engaged in the practice of citation tracking, a method involving the systematic monitoring of all the scholarly works that reference each of the papers incorporated in the collection. in conjunction with the manual search, an online search of databases was also undertaken as an integral component of the comprehensive search process. the evaluation and categorization of scholarly articles were performed by taking into account their specific domains of application. the publications were categorized based on the major research topics on gis and rs application in agriculture. following the identification of each topic, a comprehensive review was conducted, primarily on the presented issues. the emphasis was given to the current information on the utilization of gis and rs in the agricultural sector, with a focus on their role in promoting evidence-based policies and practices to enhance agricultural sustainability. additionally, this review sought to identify the challenges hindering the widespread adoption of gis and rs applications, particularly in lowand middle-income nations. this study exclusively relied on research articles published in peer-reviewed journals, ensuring the reliability and validity of the findings. the publications were thereafter evaluated to ascertain whether their main subject matter bore a resemblance to that of the present inquiry. priority consideration was given to papers published after the year 2010. the primary justifications for the elimination of papers are their lack of relevance, duplication, incomplete textual content, or limited presence of abstracts. the predetermined exclusion criteria were established to safeguard the researcher against potential biases that could influence their findings. figure 1 illustrates the progression of review criteria employed for the selection of suitable documents for review analysis. moreover, figure 2 presents the systematic review procedure utilized in the current study. after the research topic was chosen, this study proceeded to find and locate relevant articles, do an analysis and synthesis of diverse literature sources, and create written materials for article review. the synthesis phase encompassed the collection of a wide range of publications, which were subsequently amalgamated into conceptual or empirical analyses that were relevant to the finalized research. global sustainability research global scientific research 5 figure 1. the development of criteria for the selection of documents. figure 2. the procedure of systematic review conducted by the study. results and discussion gis in agriculture and policy implications the principal study themes within the current body of literature pertaining to the utilization of gis in the field of agriculture are depicted in figure 3. there are seven distinct application areas of gis within the field of agriculture. these areas encompass crop yield estimation and forecasting, assessment of soil fertility, analysis of cropping patterns and agricultural monitoring, evaluation of drought conditions, detection and control of pests and crop diseases, implementation of precision agriculture techniques, and management of fertilizers and weeds. gis can assist in implementing agricultural policies through several means. gis can facilitate the enforcement of regulations and provide a visual representation of the economic consequences of policy (boda et al., 2023; raihan & tuspekova, 2022k). gis has the capability to uncover environmental health concerns as well as issues related to animal health and welfare (niloofar et al., 2021; raihan & tuspekova, 2023a). gis has the ability to mediate land use disputes (yanbo et al., 2023; raihan & tuspekova, 2023b). gis software has the capability to examine global sustainability research global scientific research 6 soil data and monitor the advancement of a project (alaloul et al., 2021; raihan & voumik, 2022a). gis can enhance agricultural productivity and minimize expenses by facilitating improved land resource management (diehl et al., 2020; raihan & voumik, 2022b). gis enables organizations to assess crop health by utilizing data obtained from satellite imagery, thermal sensors, and multispectral cameras (olson & anderson, 2021; raihan, 2023e; sultana et al., 2023a). gis software aids farmers in identifying optimal sites and environmental factors for cultivating various crops (roy et al., 2023; sultana et al., 2023b). gis-based models offer empirically supported approaches to enhance soil quality management (tsegaye & bharti, 2021; raihan, 2023f; voumik et al., 2022; himu & raihan, 2023). the subsequent sub-sections provide a description of the main research areas explored in the current body of literature pertaining to the application of gis and rs in the field of agriculture. figure 3. major research topics on gis application in agriculture. crop yield estimation and forecasting the monitoring of crop growth and the early forecasting of crop yield in agricultural fields are crucial processes for the purpose of food security planning and the prediction of agricultural economic returns (al-adhaileh et al., 2022; raihan, 2023g; voumik et al., 2023a). according to dhanaraju et al. (2022), the ongoing progress in rs and gis technologies has resulted in enhancements to the methods and approaches employed for monitoring agricultural development and calculating crop yields. figure 4 depicts the utilization of remote sensing data to global sustainability research global scientific research 7 prepare crop yield map. numerous research have showcased the utilization of combined gis and rs technology for the purpose of estimating crop production. memon et al. (2019) showcased the efficacy of integrating multispectral landsat satellite images and comparing several remote sensing-based spectral indices in quantifying the proportion of wheat straw cover. furthermore, the study successfully determined the impact of wheat straw cover on rice crop yields. the acquisition of knowledge can contribute to the development of long-term strategies for promoting agricultural sustainability within rice-wheat cropping systems. hassan and goheer (2021) indicate that it is possible to accurately estimate wheat crop yield in advance of harvesting by utilizing vegetation indices derived from moderate resolution imaging spectroradiometer satellite imagery, coupled with crop yield data and a gis modeling approach. in a further investigation, muslim et al. (2015) employed a gis-based framework that linked climate modeling with environmental policy considerations. this approach offered a pragmatic solution for predicting rice crop yield. the study utilized a comprehensive model that integrated data at the regional level, including crop-level data, soil data, farm management data, and climatic data, in order to estimate geographic differences in crop production. figure 4. utilization of remote sensing data to prepare crop yield map. similarly, al-gaadi et al. (2016) employed the extraction of the normalized difference vegetation index and soiladjusted vegetation index from landsat satellite pictures obtained throughout the various growth stages of potato plants in order to forecast the yield of potato tubers. crop yield forecasting models that utilize gis and rs have the potential for broader application in providing valuable insights for spatially oriented agricultural strategies. as demonstrated by the findings of these models, it is possible to develop policy interventions that target the various factors influencing crop yields, such as farm management techniques, plant health, water availability, weather conditions, terrain, altitude, and policy intervention itself (mann & warner, 2017; raihan, 2023h; voumik et al., 2023b). the ability to accurately predict crop yields well in advance of harvest is of utmost importance, particularly global sustainability research global scientific research 8 in a geographical area that is known for its unpredictable climate conditions. the monitoring of agricultural crop growth conditions and the forecast of prospective crop yield play a crucial role in the strategic planning and policy formulation for ensuring food security and predicting agricultural economic returns (abhishek et al., 2023; raihan, 2023i; voumik et al., 2023c). one potential avenue for addressing this issue is the formulation of policies aimed at enhancing both the production and sustainability of agriculture (pawlak & kołodziejczak, 2020; raihan & said, 2022). in order to address the challenge of feeding a growing population in lmics, it is imperative for agricultural production systems to focus on narrowing the gap between the present yields achieved by farmers and the potential yields that can be attained in rainfed subsistence farming systems. hochman et al. (2013) aimed to resolve the discrepancy between actual and potential wheat yields. to achieve this, the researchers constructed a comprehensive model that incorporated statistical yield and cropping area data, remotely sensed data, cropping system simulation, and gis mapping. this integrated approach allowed for the assessment and mapping of wheat yield gaps. assessment of soil fertility the evaluation of soil quality holds significant importance in the development of sustainable agricultural strategies aimed at addressing the existing disparity between food supply and demand, hence contributing to the resolution of food security concerns (wijerathna-yapa & pathirana, 2022; raihan & himu, 2023). the utilization of rs datasets and gis spatial modeling approaches presents novel prospects for quantifying and assessing soil quality across various spatial extents (guo et al., 2023; raihan et al., 2023e). shokr et al. (2021) devised a soil quality model that incorporates the physical, chemical, and biological attributes of soil in a spatially explicit manner. this model was further enhanced by merging a digital elevation model with a sentinel-2 satellite image, resulting in the generation of digital soil maps. abdelfattah and kumar (2015) elucidate the utilization of a gis-enabled web-based soil information system. this system offers a comprehensive soil database that incorporates descriptive, quantitative, and geographic data, all presented through a user-friendly interface. the application of the technique was utilized to assess the capacity of soils in terms of their suitability for plant cultivation and effective maintenance. abdellatif et al. (2021) employed gis and rs technologies to construct a spatial model aimed at evaluating soil quality. the researcher's model integrated four primary indicators of soil quality, namely the soil fertility index, soil physical index, soil chemical index, and geomorphological characteristics index. additionally, the model employed gis conventional kriging spatial interpolation techniques to provide a comprehensive map of the soil quality index. the utilization of these gis-based models offers empirically supported approaches for enhancing soil quality management (raihan et al., 2023f). the implementation of this approach would provide decision-makers, policymakers, land-use planners, and agricultural professionals with the means to effectively oversee soil resources and promote the sustainable utilization of agricultural lands based on their inherent capabilities (abdelrahman et al., 2021; tunçay et al., 2021; raihan et al., 2023g). therefore, the evaluation of soil quality indicators holds significance in the context of sustainable agricultural policies and practices, as well as in the pursuit of food security. analysis of cropping patterns and agricultural monitoring in the context of climate variability, the utilization of agricultural crop monitoring analysis has the potential to assist governmental officials and farmers in formulating strategic approaches for crop planning and designing that are responsive to fluctuations in water resources (njoya et al., 2022; raihan et al., 2023h). agricultural monitoring systems incorporate various geographic data sets and cropping system models into computational algorithms in global sustainability research global scientific research 9 order to spatially calculate and simulate optimal scenarios for site-specific conditions in crop production (luo et al., 2023; raihan et al., 2023i). shafi et al. (2020) have created a crop monitoring system that combines geospatial data acquired through high-resolution remote sensing with a web-based gis geoportal interface. the existing literature provides evidence for the distinctiveness of integrating gis and rs into a tool designed for crop selection and rotation analysis at the farm level, with the aim of enhancing decision-making in crop management (kumar & babu, 2016; raihan et al., 2023j). the modeling of cropping patterns is influenced by the availability of irrigation water, which is, in turn, influenced by climate variations and policy regarding the extraction of irrigation water. wang et al. (2011) integrated gis with irrigation water availability simulation models in order to examine cropping patterns. this analysis was conducted by utilizing forecasts of irrigation water availability. according to kumar and babu (2016), the implementation of a gis that is accessible through the web can serve as a valuable tool for farmers at the individual farm level. this system would enable farmers to obtain pertinent information and make informed decisions aimed at enhancing agricultural productivity. singha et al. (2020) assert that this system possesses a broader range of potential applications in facilitating agronomic decision-making processes, such as the optimization of land and labor efficiencies, the promotion of increased cropping intensities, and the generation of improved crop yields. this practice has the potential to enhance agricultural yield and optimize crop management practices, particularly in terms of precision irrigation management, over an extended period of time. figure 5 presents the usage of internet of things (iot) and smart sensors for agricultural monitoring. figure 5. the usage of iot and smart sensors for agricultural monitoring (rajak et al., 2023). global sustainability research global scientific research 10 evaluation of drought conditions the utilization of spatial datasets derived from satellite rs and gis technology provides valuable insights for evaluating and modeling agricultural drought-risk patterns, monitoring drought conditions, and generating maps depicting drought vulnerability (mullapudi et al., 2023; raihan et al., 2023k). hoque et al. (2021) involved the integration of geospatial methodologies and fuzzy logic in order to create a complete spatial drought risk inventory model that can be utilized for effective operational drought management. the model effectively detected and characterized the geographical boundaries and patterns associated with agricultural drought vulnerability. sehgal and dhakar (2016) employed gis and high-resolution rs data to create indicators of crop sensitivity. these indicators were then utilized to establish a technique for evaluating and mapping the primary biophysical elements that contribute to vulnerability to agricultural drought, specifically at a local level. according to aziz et al. (2022), policymakers can utilize drought risk maps to develop policies that are geographically specific for mitigating and intervening in drought situations. furthermore, the utilization of vulnerability maps can serve as a valuable tool in identifying areas that need prioritization for socioeconomic development policy initiatives (isfat & raihan, 2022; saha et al., 2023; raihan & bijoy, 2023). detection and control of pests and crop diseases ahmad and sharma (2023) assert that ongoing advancements in geospatial tools and techniques are being made with the aim of assisting farmers in their efforts to control and manage crop diseases. several research have demonstrated the pragmatic utilization of satellite rs data and geospatial techniques in the context of detecting and managing crop diseases in a sustainable manner (roberts et al., 2021; raihan et al., 2018; pande & moharir, 2023). rs technology, specifically the utilization of airborne and satellite imagery during the periods of crop growth, has been employed for the purposes of early detection and mapping of certain crop diseases, as well as for managing the recurrence of diseases in subsequent seasons and evaluating the economic impact resulting from frost damage (jaafar et al., 2020; sishodia et al., 2020; raihan et al., 2019; wu et al., 2023). santoso et al. (2011) employed high-resolution quickbird satellite images to successfully identify regional distributions of oil palm plants afflicted with basal stem rot disease. six vegetation indicators were employed, which were generated from satellite imagery's visible and near-infrared bands, in order to effectively differentiate between oil palms that were healthy and those that were sick. yang (2020) demonstrated the successful implementation of site-specific fungicide applications for disease management through the utilization of precision agriculture technologies and remotely sensed imaging. in the forthcoming years, novel methodologies that employ geoinformation technology for the purpose of monitoring and managing pest and crop disease detection have the potential to mitigate the environmental impact of pesticides and herbicide chemicals. precision agriculture automated geospatial analysis and decision support algorithms in the field of precision agriculture have the potential to offer policymakers significant scientific insights, hence enhancing the creation of agriculture policies (raihan et al., 2021a; saliu & deari, 2023). the utilization of integrated gis, rs, and gps technology has led to the increasing recognition of precision agriculture methods. these practices have demonstrated their effectiveness in enhancing crop output, enabling site-specific crop management, and minimizing the use of agrochemicals (karunathilake et al., 2023; raihan et al., 2021b). toscano et al. (2019) showcased the efficacy of utilizing sentinel-2 and landsat-8 imagery for representing the spatial heterogeneity of wheat production within a given global sustainability research global scientific research 11 field. this information is crucial for the implementation of precision farming methodologies. this offered a prospective alternative to conventional farming methods through the enhancement of site-specific management and agricultural yield. garcía et al. (2020) conducted an investigation to evaluate the efficacy of remotesensing drones in serving as mobile gateways for facilitating wi-fi data transfer between sensor nodes and the gateway in precision agriculture systems. the authors aimed to provide insights into the ideal drone parameters that would ensure successful data transmission in this context. the research effectively showcased the utilization of drones as a remote sensing instrument for collecting data from field-deployed nodes to facilitate crop monitoring and management. the drones operated at a minimal pace, maintained a height of 24 m, and were equipped with an antenna providing a coverage range of 25 m. this had the potential to enhance the uptake of precision agriculture among smallholder farmers. segarra et al. (2020) had a specific objective of comprehending the characteristics of the twin sentinel-2 satellites belonging to the european space agency, as well as their utilization in the field of precision agriculture. the research conducted emphasizes the significant advancements brought about by sentinel-2 in the field of agricultural monitoring and crop management. it has greatly enhanced the detection of abiotic and biotic stresses, improved the accuracy of crop yield estimation, facilitated more precise crop type classifications, and offered a range of other valuable applications in the agricultural sector. various factors contribute to the augmentation of precision agriculture, resulting in enhanced agricultural management and environmental sustainability (elahi et al., 2022; raihan, 2024b). the utilization of satellite image-based solutions for the extraction of plantation rows plays a crucial role in various aspects of precision agriculture, including crop harvesting, pest management, and projections of plant growth rates. fareed and rehman (2020) conducted a study in which they employed gis and rs techniques to develop an automated approach for extracting plantation rows from a digital surface model derived from drone-based picture point clouds. the technique of automatic extraction of plantation rows can be employed for the purpose of quantifying damage assessment in precision agriculture pertaining to plantation rows. figure 6 presents the technologies involved in precision agriculture. figure 6. technologies involved in precision agriculture (gonzalez-de-santos et al., 2020). global sustainability research global scientific research 12 weed and fertilizer management the implementation of precise mapping techniques for weed distribution has the potential to significantly improve the effectiveness of weed management strategies. this can lead to a reduction in weed-related losses, as well as a decrease in the expenses associated with herbicide application and the optimization of fertilizer usage (chaudhari et al., 2022; raihan et al., 2022d). gis technologies were employed to generate precise maps depicting the distribution of weeds inside rice farms, which enhanced input application efficiency, reducing the utilization of inputs such as herbicides, fungicides, and labor expenses associated with weeding (dunaieva et al., 2018; raihan et al., 2022e). consequently, this led to a decrease in weed damage and a reduction in the overhead expenditures associated with crop production. the utilization of gis in the creation of a gis-based fertilizer decision support system (fdss) has been shown in the literature (xie et al., 2012; raihan et al., 2022f). this was achieved through the integration of rs data, field surveys, and expert knowledge. the researchers successfully developed a soil spatial database on the supermap platform, which proved to be valuable for effective crop management systems. the employment of fdss in agricultural production has been found to yield several advantages, including enhanced efficiency in fertilizer utilization, thus leading to a reduction in production costs. challenges in implementing gis in agricultural policy and practice in general, the utilization of gis and rs technology is not a universally effective solution for achieving evidencebased policy and practice, and it is not without its drawbacks. the efficacy of geospatial technology application is contingent upon its appropriate utilization, the availability of high-quality data, and the allocation of substantial resources for its management (raihan et al., 2022g). in nations experiencing limited resources, such as lmics, the widespread utilization and acceptance of technology are hindered by the associated expenses and insufficient proficiency in relevant competencies (raihan et al., 2022h). the task of simulating crop yield generation poses inherent challenges owing to the diverse array of cropping systems and the varying degrees of technological advancement employed (abbasi et al., 2022; raihan et al., 2022i). in order to achieve a precise evaluation of crop production gaps, it is imperative to enhance the quality of input data. this entails obtaining precise meteorological parameters, improving soil characterization, and acquiring geographically dispersed land use data (schils et al., 2022; raihan, 2024c). additionally, the implementation of instrumented geo-referenced validation sites would be necessary in order to provide full survey data that can be used to feed a continuous improvement cycle for assessing yield gaps (tantalaki et al., 2019; raihan, 2023j). therefore, the advancement of remote sensing technologies and the refinement of integrated cropping systems models would result in enhanced precision for yield gap estimation in the future. in the field of drought vulnerability assessment and mapping, a majority of research documented in scholarly literature have demonstrated a preference for employing aggregated geographical data at broader spatial scales, such as national or regional levels. however, there has been a notable absence of use of finer-scale data, specifically at the local level (raihan, 2023k). given that the impact of drought hazards is predominantly experienced and demonstrated at the local level, conducting a comprehensive mapping of drought risks at a more precise scale necessitates the utilization of high-resolution remote sensing techniques and the incorporation of locally relevant indicators. this approach is crucial in order to obtain a comprehensive understanding of susceptibility in relation to drought (raihan, 2023l). this would be of more significance to policymakers who are aiming to develop and execute mitigation initiatives at the local level. given the anticipation of heightened and more frequent drought occurrences, as well as the escalating risks posed by climate change, the integration of all spatially explicit risk factors into drought risk mapping would constitute a valuable and effective addition to measures aimed at global sustainability research global scientific research 13 mitigating drought impacts (raihan, 2023m). there is a need for further acquisition of skills and knowledge pertaining to the application of geospatial techniques in the context of agricultural drought risk. in the domain of agricultural disease identification, there persist issues pertaining to the accurate mapping of such diseases through the utilization of aerial or satellite imaging (raihan, 2023n). while satellite imaging has proven effective in detecting and mapping several crop diseases, it is important to note that each disease possesses unique characteristics that necessitate distinct approaches for detection and management. yang (2020) asserts that the identification of certain diseases poses challenges, particularly when there are several biotic and abiotic factors that have similar spectral features within a given field. the identification of recurring diseases necessitates the utilization of consistent historical images and spatial-temporal data, whereas the detection of developing diseases poses greater challenges. yang (2020) asserts that there is a need for the development of more sophisticated rs imaging sensors and image-processing systems in order to effectively distinguish diseases from other factors that may cause confusion. in underdeveloped nations, there is a limited number of farmers possessing the requisite expertise for utilizing rs technologies in the generation of prescription maps, the execution of disease control strategies, and the administration of site-specific fungicides (raihan, 2023o). further investigation is warranted in the advancement of integrated geospatial analytical approaches and technologies to assist farmers in identifying various crop diseases. the utilization of precision agriculture technologies has the potential to enhance crop optimization and support decision-making in agricultural management, thereby addressing the issue of food insecurity in lmics (raihan, 2023p). however, the successful implementation of precision farming necessitates the adoption of geospatial technology and the acquisition of substantial quantities of high-resolution spatiotemporal data (raihan, 2023q). the deficiency in proficiency in using gis and rs technologies in lmics can be addressed by the widespread distribution and adoption of realistic geospatial technology from more industrialized nations (roberts et al., 2021; raihan, 2023r). nevertheless, the successful implementation of precision agriculture methods in lmics requires substantial investments in information and communication technology (ict) infrastructure. the evaluation of soil fertility is widely recognized as a crucial parameter in precision farming and the sustainable management of agricultural lands based on their inherent capabilities (raihan, 2023s). the establishment of a comprehensive soil information system is necessary. nevertheless, as asserted by abdelfattah and kumar (2015), a significant portion of the global population lacks access to comprehensive soil quality data. in lmics, there is a notable increase in the fragmentation of agricultural land into smaller plots that are economically unviable, accompanied by the adoption of unsustainable farming practices (raihan, 2023t). further investigation is warranted to explore the potential of active remote sensors in assessing soil quality within a dynamic and evolving context. one of the challenges hindering the utilization and acceptance of gis and rs in the agricultural sector is to the absence of universally recognized standards for data interoperability (raihan, 2023u). despite the growing accessibility of spatial data utilization in lmics, a significant challenge arises from the inherent susceptibility of these data to errors (raihan, 2023v). furthermore, the collection and storage of such data in lmics may involve disparate spatial units, formats, metadata, as well as variations in time and space intervals (raihan, 2023w). these factors render certain data impractical for use, impede the integration of spatial data, and impede the comprehensive analysis of data, particularly when it is acquired from several sensors and platforms (raihan, 2023x). there is a necessity to establish universally accepted protocols for the development of standardized rules pertaining to geographical data in the field of agriculture (raihan, 2023y). it is of utmost importance to provide training to academics, practitioners, and farmers on the proper methods for collecting spatial data that is both high in quality and accuracy, ensuring its usability across several platforms. enhancing the interoperability of spatial data repositories has the potential to facilitate data integration and enhance the efficacy of data analysis. global sustainability research global scientific research 14 crowdsourced data collecting has promise as a valuable contribution towards the development of cost-effective agri-spatial data repositories. conclusions and policy implications this study has examined diverse methods in which gis technology has been incorporated within the agricultural sector to enhance decision-making processes and inform policymaking efforts. gis and rs technologies offer more effective methodologies for analyzing spatial elements that impact agricultural production in comparison to methods that lack geographically explicit data. when effectively utilized, the spatially integrated knowledge offered by gis and rs can be utilized to augment agricultural policy and evidence-based interventions aimed at enhancing agricultural sustainability. despite the potential of gis technology to enhance agronomic practices, their utilization in many lmics is limited. this is concerning, as many countries are in urgent need of upgrading their agriculture and food production techniques. in order to optimize the utilization of gis and rs technologies, it is imperative for governments and farmers in lmics to enhance their understanding and possible application of spatial data pertaining to agricultural practices. advancements in geoinformatics methods and computing infrastructure have the potential to facilitate a more collaborative framework among various stakeholders, including scientists, researchers, policymakers, academics, crop consultants, extension employees, and agricultural machinery and chemical dealers. this framework aims to provide practical guidelines for the effective management of crop production estimations, fertility of the soil, cropping patterns and monitoring, drought risks, as well as fertilizer and weed management. to bolster evidence-based agricultural policy, government entities and policymakers necessitate robust empirical data that facilitates a comprehensive comprehension of the intricate and interrelated elements influencing agricultural productivity. consequently, this would facilitate the development of specific intervention techniques. moreover, it is imperative for a diverse range of stakeholders and professionals in the field of agriculture to have access to geographically relevant agricultural data in order to effectively implement a multitude of strategies aimed at enhancing agricultural productivity. similarly, it is crucial for smallholder farmers to have access to synthesized information in order to empower them to make educated decisions based on evidence. this knowledge is also necessary for them to effectively undertake practical activities that can enhance agricultural productivity. the aforementioned statement highlights the growing need for the integration of gis in the processes of formulating and implementing agricultural policies. gis and rs technologies possess considerable potential in the evaluation, preservation, manipulation, and generation of agricultural data. the data holds potential value in several applications such as precision agriculture, site-specific farming, and disease detection, with the overarching goal of enhancing agricultural food production and addressing food security concerns. regrettably, the absence of reliable spatial data in numerous local government entities persists as a hindrance to decision-making processes, policy development, and the subsequent execution thereof. in instances where such data is available, there is a prevailing deficiency in the proficiency of individuals in utilizing gis and rs spatial analytical tools. the attainment of agriculturally integrated policies that encompass geographical dimensions necessitates the use of comprehensive and current spatial datasets, as well as improved methodologies that effectively amalgamate and analyze intricate data from diverse origins in order to generate valuable insights. this would require both national and local governments to implement methodologies, approaches, and methodologies that enable the gathering and examination of various agricultural datasets, thereby offering comprehensive insights to policymakers, planners, farmers, and a wide range of stakeholders involved in the agricultural industry. gis offers a promising avenue for obtaining comprehensive and current spatial datasets, as well as improved spatial analytic techniques capable of effectively evaluating intricate data to generate valuable global sustainability research global scientific research 15 insights. if appropriately adopted and implemented, gis has the potential to increase the spatial decision support system, hence boosting the efficiency and efficacy of agriculture policy development and planning. however, the implementation of policy change necessitates the presence of both public and political will in order to effectively lead and stimulate actions. consequently, the implementation of gis technology in the policymaking process necessitates the allocation of public monies by local government entities to establish the necessary software, hardware, supportive infrastructure, and staff training. future research endeavors may prioritize the examination of how gis and rs technologies might facilitate the establishment of a collaboration framework among scientists, policymakers, researchers, and extension agriculture officers. this collaborative framework aims to enhance the promotion of sustainable and climate-smart farming methods, with a particular emphasis on lmics. declaration acknowledgment: n/a funding: this research received no funding. conflict of interest: the author declares no conflict of interest.

hemp; fiber; industry; environment; sustainability introduction global environmental issues are being exacerbated by the current climate changes on the planet, which are mostly the result of human activity (raihan et al., 2022a; abbas et al., 2023). some of the results of these issues are overpopulation, climate change, and the loss of biodiversity. the literature confirms that these phenomena arise from the irresponsible consumption of natural resources (jaafar et al., 2020; begum et al., 2020; voumik et al., 2022; raihan, 2023a). ecological, economic, and agricultural sustainability are interdependent and necessary for environmental protection (agrawal et al., 2022; ibarra et al., 2023; raihan, 2023b). sustainable farming options have recently garnered a lot of attention from farmers all around the world (raihan et al., 2023a; sharma et al., 2023). hemp, often known as the cannabis plant, is attracting interest as a sustainable crop with great potential (rivas-aybar et al., 2023). cannabis is thought to have originated in east and central asia before spreading throughout the rest of asia and, eventually, to europe (wani et al., 2023). industrial hemp, also known as cannabis sativa l., is cultivated for its fiber, oilseed, medicinal, and recreational uses (visković et al., 2023). global sustainability research global scientific research 2 the cannabis plant is an annual herb that can reach heights of 1 to 6 meters and is dioecious in nature (agate et al., 2020). hemp, one of the world's fastest-growing plants, is an annual with a complex leaf structure (kaur & kander, 2023). besides improving air quality, thermal balance, and environmental impact, cannabis plants can remove up to 10 metric tons of carbon dioxide from the air in a single vegetation cycle (zimniewska, 2022). the cannabis plant has a high yield when it comes to fiber production; on the same amount of land, it may generate 250% more fiber than cotton and 600% more fiber than flax (rupasinghe et al., 2020). figure 1 presents the benefits of the hemp apparel industry. cannabis plants can be produced without the use of herbicides because their dense canopies shade out weeds and reduce the number of soil-dwelling fungi and nematodes (adesina et al., 2020). because of how firmly it anchors its roots in the ground, the cannabis plant helps preserve soil quality by preventing erosion and nutrient leaching. it also aids in phytoremediation by removing pollutants such as heavy metals from the soil and preserving them inside the plant (cleophas et al., 2022). throughout the growing season, leaves fall to the ground, providing a steady supply of wet organic matter (rupasinghe et al., 2020). the cannabis plant is an excellent option for use in crop rotation plans to enhance the production of the primary crop because of its role in enhancing the soil quality. if cannabis cultivation is handled correctly, the plant is predicted to be a sustainable and environmentally benign crop (adesina et al., 2020). farmers who cultivate the cannabis plant have the option of using fewer herbicides, rotating crops, and eventually becoming certified as organic (visković et al., 2023). the agricultural sector is interested in cultivating cannabis due to its environmental benefits and the expanding market for hemp products (quaicoe et al., 2023). growing, processing, using, recycling, reusing, biorefining, and waste management—the entire value chain of the cannabis plant—satisfies the principles of sustainability tactics and can aid in combating climate change (kaur & kander, 2023). figure 1. the benefits of the hemp apparel industry. global sustainability research global scientific research 3 many different plants, notably hemp and marijuana, are produced by the cannabis genus. cannabinoids, which are found in high concentrations in cannabis, each have their own unique physiological effects in humans, numbering over a hundred (simiyu et al., 2022). the two most studied cannabinoids are tetrahydrocannabinol (thc), the psychoactive component responsible for the "high" associated with cannabis, and cannabidiol (cbd), a safe, non-addictive, and non-hallucinogenic substance known for its medicinal properties. profile (johnson, 2019). bud, oil, and tinctures containing cbd are on the market for the purpose of reducing inflammation and stress (iseger & bossong, 2015; hameed et al., 2023). because of its intoxicating effects, thc is prohibited in many countries despite its widespread medical and recreational usage (bridgeman & abazia, 2017). hence, it is imperative to differentiate between the several classifications of cannabis sativa l., namely marijuana and industrial hemp, in order to engage in lawful cultivation practices. the determination of the thc concentration threshold on a dry weight basis is commonly employed as the primary criterion for distinguishing between the two unique types. on a dry weight basis, thc concentrations in industrial hemp are typically below 1%, but in marijuana can range from 3% to 15% (rupasinghe et al., 2020). industrial hemp's validity varies across different locations and countries. producing hemp with high concentrations of psychoactive cannabinoids is illegal in most countries, including the european union (eu), in order to deter its usage for recreational purposes (sgrò et al., 2021). the eu regulations impose the most stringent limitation on thc concentration, capping it at 0.2%. in comparison, mexico allows up to 1.0% thc, malaysia permits 0.5% thc, and the majority of countries, including america, canada, china, and east asian countries, set the maximum at 0.3% thc (zhao et al., 2021). research into cannabis has been hampered for decades by the plant's widespread prohibition, slowing the development of policies and agricultural extension guidelines needed to minimize adverse environmental outcomes (wartenberg et al., 2021; clarke & fitzcharles, 2023). as a result, people's ability to assess the whole range of beneficial effects and dangers shrank. however, the global trend toward legalizing and decriminalizing cannabis sativa has accelerated in recent years (yousufzai et al., 2023). because of this, researchers have begun to focus more on the plant and its many potential applications (simiyu et al., 2022). governments, individual researchers, and corporations from all around the world have recently expressed an intense curiosity about industrial hemp (kaur & kander, 2023). proponents of cannabis legalization point to the plant's environmental benefits, adaptability to different agronomic circumstances, and myriad uses to argue that it should be legalized as a cash crop for farmers (taylor et al., 2023). it has been suggested in research that the cultivation of the cannabis plant could be financially rewarding if treated like any other commercial agricultural entrepreneurship (kaur & kander, 2023). however, due to global limitations and restrictions on industrial hemp production, much of the existing research on the sustainability potential of the cannabis plant is based on notions that have not been validated or are already out of date (visković et al., 2023). therefore, this study seeks to fill these gaps by reviewing the existing literature on industrial uses of the cannabis plant and its sustainability from multiple points of view of economic, environmental, and social sustainability. in addition, this study portrays how the cannabis plant contributes to achieving the united nations' sustainable development goals (sdgs). this research has the potential to contribute to the development and implementation of appropriate policies aimed at the global legalization of the cannabis plant, as well as the promotion of industrial hemp, with the ultimate aim of accomplishing the sdgs. methodology the present study employed the systematic literature review methodology as suggested by tawfik et al. (2019). according to benita (2021) and raihan (2023c), the systematic literature review framework is considered to be a reliable approach. a preliminary review of the literature was conducted to identify pertinent articles, validate the proposed idea, avoid redundancy with previously covered issues, and ensure the availability of sufficient articles for conducting a comprehensive analysis of the subject matter. both scholarly and gray literature were identified and sourced using a global google scholar search of the literature on industrial hemp, its applications, and its global sustainability research global scientific research 4 sustainability. the industrial application and long-term viability of the cannabis plant are examined by reviewing a variety of publications covering the time span from 2000 to 2023. "cannabis sativa," "industrial hemp," "parts of the hemp plant," "hemp fiber," "hemp seed," "hemp oil," "uses of industrial hemp," "hemp global production," "pillars of sustainability," and "hemp and sustainability" are only some of the search keywords used in this literature study. the google scholar search returned almost a thousand results. peer-reviewed publications, book chapters, and government and international agency reports were filtered into a second search. the study then analyzed the titles, keywords, and abstracts of the search results to determine how relevant they were. for instance, documents were omitted if they failed to address the present applications of industrial hemp or the sustainability of hemp. figure 2 illustrates the development of review criteria employed for the selection of suitable documents for review analysis. figure 2. the development of criteria for the selection of documents. the comprehensive literature review encompassed a total of 86 distinct scholarly documents. the present study implemented a data verification process, wherein each included article was cross-checked with its corresponding entry in an extract sheet using visual evidence. it is noteworthy to mention that of the 86 documents subjected to qualitative synthesis, only those publications containing relevant material were cited in the reference list contained in the manuscript. this implies that certain articles were not included in the reference list. figure 3 illustrates the systematic review procedure utilized in the current study. after the research topic was chosen, this study conducted a systematic search for relevant publications, analyzed and synthesized information from diverse literature sources, and prepared written materials for article review. the synthesis phase encompassed the collection of a wide range of publications, which were subsequently amalgamated into conceptual or empirical analyses that were relevant to the finalized research. global sustainability research global scientific research 5 figure 3. the procedure of systematic review conducted by the study. usage of cannabis plant seeds, stems, flowers, leaves, and roots are all components of the cannabis plant. figure 4 depicts various components of the cannabis plant. hemp fiber is the stem and stalk of the industrial hemp plant. hemp fiber production requires preventing the plant from spreading out and flowering. plants are spaced at a density of 3550 per square foot. ten to fifteen feet is the optimal height at which to harvest cannabis plants for fiber (johnson, 2019). the outside layer of a hemp stem is made up of bast fiber bundles, which are more valued than the inner layer, which is made up of hurd or shive fiber bundles, which are less expensive woody components (john, 2019; kaur & kander, 2023). figure 5 shows the hemp stem separated into fiber and hurd. figure 4. various components of the cannabis plant (simiyu et al., 2022). global sustainability research global scientific research 6 figure 5. the stem fibers and hurd derived from the cannabis plant (kaur & kander, 2023). the hurd of a hemp stem accounts for 85% of its biomass (li et al., 2018), while the bast fiber only accounts for 15%. using a decorticator, retting, or both, the core fibers are mechanically removed from the bark to create fiber. after being cleaned, dried, and bale, hemp fibers can undergo further mechanical separation to undergo processes including cottonizing, shredding, and spinning into yarn. oilseeds are obtained from the seeds of industrial hemp plants (kaur & kander, 2023). growing hemp plants for their seeds is quite similar to growing hemp plants for their fiber. seeds and grains from cannabis plants can be harvested when they reach a height of 6 to 9 feet (johnson, 2019). hemp seeds range in size from about 1/8 to 1/4 inch and have a smooth exterior. figure 6 is a cross-sectional view of a hemp seed from the side. during seed processing, the seed kernels are separated from their hulls (kaur & kander, 2023). figure 6. a side view and cross-section of a hemp kernel. flower buds and other floral components on cannabis plants are collected for extraction of cbd and other oils. flower buds and other floral materials can be cultivated by encouraging the development of wider branches and leaves. hemp is spaced out more, typically between three and five feet, so that the plant has room to spread its global sustainability research global scientific research 7 roots and shoots (johnson, 2019). flowers on industrial hemp plants can be harvested when they are between four and eight feet tall. lipid infusion, carbon dioxide extraction process, and solvent-free extraction are all necessary for oil production (johnson, 2019). while hemp produced for seeds and grain produces 800 to 1000 pounds per acre, hemp farmed for fiber produces 2,000 to 11,400 pounds of entire dry stems per acre. according to kaur and kander (2023), each hemp plant may produce roughly one pound of dry flower buds. cannabis is a versatile plant in that nearly every part of it can be utilized (simiyu et al., 2022). hemp is one of the most rapidly reproducing plant species, and its fiber, seeds, and oil can be used in a variety of ways (kaur & kander, 2023). multiple commercial applications for the cannabis plant are shown in figure 7. the dehulled or unhulled seeds can be used in cooking, as animal feed, in cosmetics, or pressed into oil using a cold process (montero et al., 2023). the stem can be harvested for its shives (hurd), which can be used as animal bedding, as well as its fiber, which can be made into paper or textiles (naeem et al., 2023). essential oils, among other things, can be extracted from the hemp flower for application in cosmetics and medicines (farinon et al., 2020; arif et al., 2023). more than 25,000 products are made from industrial hemp around the world in various industries such as paper, fabrics and textiles, construction and insulation materials, home furnishings, yarns and spun fibers, carpeting, and bio-composites owing to the expanding global industrial hemp market (kaur & kander, 2023). figure 7. various industrial applications of the cannabis plant (kaur & kander, 2023). it's possible to extract useful components from the cannabis plant, which could be employed in a variety of applications (martinez et al., 2023). figure 8 is a schematic illustration of the many possible applications of the cannabis plant. hemp fiber is a renewable source of bast fiber and is used in a wide variety of industrial applications (chaowana et al., 2024). hemp fibers have been used for a variety of uses, including the production global sustainability research global scientific research 8 of paper, rope, and textiles (naeem et al., 2023) due to their strength, resilience, and length (fiber bundles can reach 1-5 m). high-quality fabrics used in the global apparel industry can be woven from the hemp plant's fibers (kozlowski & muzyczek, 2023). hemp fiber production is more sustainable and uses less water than conventional cotton farming (yano & fu, 2023). as an alternative to artificial, flammable synthetics, hemp is utilized to reinforce carpets that are resistant to rotting and fire (filer, 2022). the market share for textiles, fabrics, and garments made from hemp fiber has expanded due to a growing worldwide preference for eco-friendly products from nature and sustainable systems (gedik & avinc, 2020; raihan et al., 2022b). figure 8. the diverse potential applications of the cannabis plant as a raw material (zimniewska, 2022). the pulp and paper business has long faced formidable competition from the cannabis plant. hemp fiber, which makes up about 20%-30% of hemp stalks, is used to make eco-friendly paper (tutek & masek, 2022). in the car business, hemp fiber is utilized to manufacture dashboards, seats, and other interior components. however, the extracted hemp oil is an eco-friendly additive to paints and varnishes (nachippan et al., 2021; visković et al., global sustainability research global scientific research 9 2023). a wide variety of goods, including horticultural planting materials, biodegradable mulching material, building-construction components, insulating materials, hurd-produced animal bedding, plastic biocomposites, and compressed cellulose polymers, are made from hemp fiber (kaur & kander, 2023) for a variety of uses. in agriculture, hemp straw is utilized as fodder because of the high nutritional value it provides for livestock, especially cattle (wang et al., 2023). industrial hemp is of interest to a variety of businesses due to the vast ecological potential associated with the cannabis plant and the variety of raw materials it can offer (malabadi et al., 2023). figure 9 exhibits some of the possible applications of the cannabis plant. figure 9. potential industries that could use the cannabis plant as their main raw material (tutek & masek, 2022). for a long time, hemp seed was a crucial staple crop (crescente et al., 2018; visković et al., 2023). in addition to the many critical nutrients, antioxidants, and vitamins suggested for human beings (jeliazkov et al., 2019; burton et al., 2022; strzelczyk et al., 2023), it also contains 35% edible oil (hidayet & tolu, 2023). whole and dehulled hemp seeds, hemp flour, hemp oil, hemp seed cake (the residue of mechanical oil extraction), hemp seed meal, hemp hulls, and hemp protein extracts and concentrates are all products derived from hemp seeds (burton et al., 2022; frankowski et al., 2023). oil extracted from hemp seeds is used to make salad dressing, and the oil and the seeds themselves are both high in healthy omega-3 fats and protein (strzelczyk et al., 2023). figure 10 shows the methods used to make the most common varieties of hemp seed-based ingredients for food. however, cbd oil is a non-psychoactive cannabinoid chemical derived from industrial hemp, and it does not have the same addictive properties as thc (sun, 2023). several nations have recently legalized cbd oil due to its potential health advantages and lack of addictive properties (fauziah & runturambi, 2023). cbd is utilized in a wide variety of items, including carbonated water, lotions, and pharmaceutical compounds, despite claims that it has beneficial health effects (kaur & kander, 2023). research potential in these subfields is promising (jeliazkov et al., 2019). global sustainability research global scientific research 10 figure 10. processing employed to produce the most common forms of food ingredients derived from hemp seed (burton et al., 2022). the entire food sector, notably organic food, presents a strong rivalry for hemp-based food products. incorporating hemp-based foods into diet is good for health (malabadi et al., 2023). they influence cell regeneration, aging processes, cancer cell development inhibition, and immunity significantly (fike, 2016; sheik et al., 2023). according to research by kaniewski et al. (2017), hemp seeds are loaded with antioxidant-rich nutrients like iron, calcium, zinc, phosphorus, magnesium, and vitamin e as well as micro and macro elements like edestin, choline, phytic acid, trigonelline, chlorophyll, lecithin, and vitamin k. furthermore, it has a beneficial impact on the circulatory system by increasing blood vessel elasticity, enhancing blood flow, and decreasing the risk of ischemic heart disease and atherosclerosis (tutek & masek, 2022). heart disease is a major problem in the developed world in the 21st century, however eating hemp cuisine can help reduce the risk of heart attack and improve the digestion process (apostol, 2017). hemp seed oil has several uses in the cosmetics industry (jeliazkov et al., 2019; sarkar & sadhukhan, 2023). recently, a popular trend in the cosmetics business has been the use of hemp-derived ingredients (naeem et al., 2023). hemp-based cosmetics make use of hemp oil and extracts that contain regenerative, anti-aging, and antiinflammatory ingredients. hemp oil is classified as a "dry oil" due to its rapid absorption and lack of residual greasiness. many companies now make cosmetics like lotions, oils, soaps, shampoos, and conditioners that contain hemp oil (sarkar & sadhukhan, 2023). the cbd and resin portions of hemp extract are responsible for the sedative and relaxing effects (malabadi et al., 2023). hemp compounds are gaining popularity in the pharmaceutical and medical industries as well. nutritional issues, as well as post-traumatic stress disorder (ptsd), melancholy, anxiety, sleep disturbances, constipation, convulsions, and degenerative diseases like alzheimer's, are the subjects of recent research (pintori et al., 2023). cbd has also been studied for its potential to treat cancers in the brain, breast, prostate, skin, pancreatic, and colon (afrin et al., 2020; rupasinghe et al., 2020; almeida et al., 2021; pugazhendhi et al., 2021; hasan et al., 2022; nahler, 2022; o’brien, 2022; pennant & hinton, 2023; praphasawat et al., 2023; kaur et al., 2023; sheik et al., 2023). global sustainability research global scientific research 11 sustainability of cannabis plant the economy, the environment, and society are the traditional cornerstones of sustainability (raihan et al., 2022c; raihan, 2023d). as a renewable resource, hemp is consistent with all three tenets (kaur & kander, 2023) of sustainability. economic sustainability of hemp sustainability in business is essential for ensuring economic sustainability, which is defined as the preservation of capital (huang et al., 2022; raihan & tuspekova, 2022a; raihan, 2023e). the economics of hemp are intricate, as they are with many other kinds of industrial plants (kaur & kander, 2023). although hemp has been traded for millennia, the hemp business and its supply chain actors such as hemp producers, manufacturers, processors, input suppliers, retailers, and consumers are today experiencing significant economic difficulties (mark et al., 2020). three things about the cannabis industry's finances are stable despite the industry's dynamic nature. to begin, the cannabis plant has several potential uses and applications (visković et al., 2023). second, although only a fraction of the total market for these goods, sales of hemp food, clothing, toiletries, medicines, and nutritional supplements are on the rise (kaur & kander, 2023). finally, corporate and policy shifts, infrastructure investment, and enhanced production methods have contributed to a resurgence in the cultivation of hemp throughout the past decade (mark & will, 2019), despite its dropping production worldwide due to its link with marijuana since the 1950s. the cannabis plant has enormous untapped potential in a wide variety of contexts. the cannabis plant is one of the most essential plants within the bioeconomy, as seen from the agriculture sector, consumers, industry, the circular economy, and the environmental standpoint (kaur & kander, 2023). it is anticipated that the value of the hemp market worldwide will increase fourfold in the next years, from $4.7 billion in 2020 to $18.6 billion by 2027 (zimniewska, 2022). over the projection period, annual growth is anticipated to average 15.8%. hempbased products, for instance, seeds for oil, food, and beverages, and fibers used for technical applications, such as a composite used primarily for automotive and construction projects, but also in the textile industry, have become increasingly popular, especially in developing regions like the asia pacific (crini et al., 2020). even though the full potential of the cannabis plant has not been tapped, the hemp business in europe is expanding rapidly (kaur & kander, 2023). from 2015 to 2022, hemp production in europe saw a 60% growth in acreage (visković et al., 2023). currently, it is estimated that europe cultivates up to 25% of the world’s hemp. france is the third biggest producer of industrial hemp worldwide (kaur & kander, 2023). france produces 60% of all eu output, next to germany (17%) and the netherlands (5%). figure 11 displays the annual trend of agricultural land for hemp cultivation in the eu compared to canada and china. positive economic and ecological effects on agricultural systems (raihan et al., 2023b) are realized through the integration of agriculture and energy in "agrivoltaics," where solar modules are placed above hemp crops (panchenko et al., 2021). the growth of the hemp food components market is being fueled, in part, by the increasing acceptance of hemp seed in the food supply (tripathi et al., 2023). estimates for the size of the global market for industrial hemp in 2025 range from usd 5.6 billion to usd 26.6 billion (burton et al., 2022). the market is being pushed forward by rising textile sector demand and supportive government initiatives. in response to rising worldwide demand and decreased production costs, hemp cultivation has exploded across the asia– pacific area. growth in the area is anticipated to persist through 2028 (kaur & kander, 2023). as a result of its growth, businesses and academic institutions are devoting more resources to creating cutting-edge goods. the possible cure for chronic diseases like diabetes is one important field of study, as is the development of biofuel and bioplastics. according to naeem et al. (2023), the expansion of the hemp market is anticipated to be spurred by the variety of potential applications for the plant. global sustainability research global scientific research 12 figure 11. agricultural land for hemp cultivation in the eu compared to canada and china. about 30 nations across europe, asia, north america, and south america have legislated the cultivation of the cannabis plant (kaur and kander, 2023). canada dominates the global market for hemp-based goods such as hemp oil, hemp seeds, and hemp protein powder (crini et al., 2020). moreover, china produces about half of the world's supply of hemp fiber (mcgrath, 2019; sun, 2023). seventy percent of china's hemp output is textiles, while the other thirty percent is cbd products, cosmetics, food, and vitamins (sun, 2023). when it comes to both industrial hemp and consumer textiles, china is often regarded as an industry leader (horner et al., 2019; sun, 2023). hemp has been farmed for thousands of years in china, however from 1985 to 2010 it was illegal to cultivate either the fiber or the seed. its output has been rising quickly in recent years, and this trend is anticipated to continue (mcgrath, 2019; kaur & kander, 2023). in addition, hemp is grown in many european countries, with production rising sharply in recent years (chaowana et al., 2024). among the many uses for hemp, hurds, organic seeds for food, hemp fiber for vehicle composites, pharmaceuticals, and the increasingly popular cannabidiol (cbd) are among the most common in the european union (mark & will, 2019; kaur & kander, 2023). hemp businesses can turn a profit if their hemp oils, fibers, therapeutic ingredients, and health supplements are competitive with the prices of similar products (naeem et al., 2023). hemp growers need to weigh the crop's profitability against that of competing crops and foreign hemp imports (kaur & kander, 2023). as legal markets for cannabis develop and illegal markets continue to thrive, policymakers are tasked with regulating cannabis cultivation, distribution, and consumption in new ways. the combined economic values of legal and illicit global cannabis markets have been estimated at $214−344 billion (wartenberg et al., 2021). legal markets are projected to grow significantly by 2025. still, today’s global markets remain dominated by illicit channels. while accurate estimates of cultivation area and production quantities are not feasible due to a lack of empirical data, the cultivation of the cannabis plant has been reported in 151 countries for the period of 2010−2018, highlighting the broad geographical scope of production activities. today, most cultivation appears to be outdoors; however, there have been indications of recent increases in indoor cultivation, particularly in the united states, canada, chile, uruguay, colombia, and ecuador. global sustainability research global scientific research 13 environmental sustainability of hemp the goal of environmental sustainability is the long-term conservation of natural resources for human use (raihan & tuspekova, 2022b; raihan et al., 2023c). the cannabis plant aids biodiversity, absorbs a lot of carbon, which helps slow down global warming (raihan, 2023f), and doesn't need a lot of fertilizer or pesticides, so it's good for the environment (dhondt et al., 2021). hemp is either a carbon-neutral or a carbon-negative plant, based on the cultivation and processing techniques used. according to adesina et al. (2020), cannabis plants can take up roughly 22 tons of carbon dioxide per hectare. through photosynthesis and subsequent bio-sequestration, highbiomass crops like hemp can store carbon in the plant's body and roots. most of the plant's carbon is found in the stem, while only a small amount is kept in the roots and leaves (raihan & tuspekova, 2022c; raihan, 2023g). a minimum of 13 tons of biochar may be produced from one acre of hemp every year (adesina et al., 2020; naeem et al., 2023). in addition, the extended shelf life of hemp products means that the carbon the plant stores is unlikely to be released back into the environment for quite some time (parvez et al., 2021). specifically, bouloc et al. (2013) found that the lifespan of hempcrete is greater than 30 years. moreover, plastics made from hemp could be a good way to keep polymers useful while minimizing our ecological footprint (naeem et al., 2023). these bioplastics are low-cost biomaterials that could be used to replace petroleum products, and they are reinforced with natural fibers. the incorporation of fiber makes them more durable, recyclable, and environmentally friendly (naeem et al., 2023). the fibers from cannabis plants may also be utilized for manufacturing eco-friendly paper. there is an urgent need for alternate sources because the paper industry's reliance on trees as a significant raw resource causes severe environmental degradation (raihan & tuspekova, 2022d; raihan, 2023h). the paper made from the cannabis plant is more eco-friendly and of higher quality than paper made from trees. hemp paper is extremely eco-friendly, as it requires less water, land, pesticides, and fertilizers than conventional paper (simiyu et al., 2022). three to four times as many papers can be made from a single hectare of hemp as from the same acreage of forests, and the plant matures in a fraction of the time it takes trees to do so. unlike its wood pulp counterpart, hemp paper production does not necessitate the felling of ancient trees that give off life-sustaining oxygen or the use of toxic chemical procedures. there are seven times as many opportunities to use recycled hemp paper as there are to use wood. hemp paper made in this way doesn't need to go through a damaging bleaching procedure and the production process might utilize significantly less sulfur and acid chemicals (tutek & masek, 2022). the cannabis plant has numerous positive effects on the agriculture and environment as the plant can be used as a renewable industrial raw material (gedik & avinc, 2020; tutek & masek, 2022). the extensive root system of the cannabis plant has been shown to have positive agronomic effects, including reduced fertilizer and pesticide consumption and increased soil oxygenation (cherney & small, 2016; visković et al., 2023). it's great for using as a rotation crop as well (barnes et al., 2023; liu et al., 2023). the long taproot and extensive origin system of the cannabis plant have been shown to prevent soil disintegration and improve topsoil quality when the plant is cultivated in a multi-crop system (ranalli & venturi, 2004; kaur & kander, 2023). the cannabis plant can thrive with far less water and less chemicals than other natural fiber plants like cotton (visković et al., 2023). farmers who care about the environment should consider the environmental impacts of their farming practices at every stage, from planting to harvesting and processing (raihan & tuspekova, 2022e; kaur & kander, 2023). the cannabis plant, in general, has a lower environmental impact than many other plant species, and this benefit will grow when new methods of harvesting are developed (visković et al., 2023). moreover, recent research has found that hemp is exceptionally compatible with biodiversity (kaur & kander, 2023). the potential application of cannabis plants in the restoration of mine shafts is intriguing and should be emphasized. the cannabis plant is well suited for introduction as a pioneer organism in post-mining and damaged heap regions because of its excellent resilience to pests and diseases. with their ability to bind heavy metals in their system, contaminated soil can be cleansed quickly and ecologically, making way for the reintroduction of native plant and animal species (crini et al., 2020; visković et al., 2023). the cannabis plant can be utilized to global sustainability research global scientific research 14 detoxify soil of toxic metals, such as lead, nickel, cadmium, and other harmful elements and substances as part of a bioremediation project. in addition, the cannabis plant can produce eco-friendly materials such as carbonsequestering polymers, heat-insulating materials, and concrete replacements that are both long-lasting and lightweight (visković et al., 2023). hemp can be exploited as a feedstock for the production of heat, electricity, or fuel when the entire plant, including its low-grade fibers or hurds, is utilized (visković et al., 2023). in order to provide heat, hemp biomass that has been compressed into pellets and then burned can be used in household wood stoves. utilizing hemp as a crop for the purpose of producing electricity can be scaled up to produce "green" energy from generators if the biomass is converted into charcoal first. it is possible that this might be used to replace the combustion of coal in the cogeneration process, which now relies on residue from forestry and agriculture (parvez et al., 2021; raihan & tuspekova, 2022f). figure 12 below demonstrates how the cannabis plant can be used as an amazingly effective biomass in the production of both thermal and electrical energy. hemp-based biofuels have been recognized as one of the most effective tools for reducing dependency on imported oil while decreasing greenhouse gas emissions (karche, 2019; raihan & tuspekova, 2023; yano & fu, 2023). this biofuel has the potential to lessen our dependence on fossil fuels and help maintain a healthy environment (marrot et al., 2022; raihan & tuspekova, 2022g; raihan et al., 2023d). because of their large biomass and rapid growth, cannabis plants are ideally suited to be utilized as a biofuel crop (chaowana et al., 2023). hemp is more effective in reducing greenhouse gas emissions than oil seed rape (osr) and sugar beet, two crops utilized for bioenergy generation in europe (simiyu et al., 2022). hemp's dual use as a biofuel does not pose an immediate threat to food security because it is not a staple food crop. therefore, it has been determined that hemp is a superior fossil fuel alternative to osr biodiesel and sugar beet bioethanol. another study evaluating the bioenergy potential of several crops found that cannabis generated more money per hectare than kenaf, switchgrass, and sorghum (das et al., 2017). carbon emissions and global warming may be reduced significantly if fossil fuels were replaced with biofuels (raihan et al., 2023e) made from the cannabis plant. figure 12. processing cannabis for energy purposes (tutek & masek, 2022). global sustainability research global scientific research 15 social sustainability of hemp investing in and providing for society's essential services and infrastructure are examples of social sustainability. it can be fostered within a society to improve communication, self-control, and morality (kaur & kander, 2023). nurturing principles, interactions, and socialization are all aspects of human sustainability that are interconnected with social sustainability. the economic and ecological effects of the cannabis plant provide evidence of its social sustainability. as a result of its many applications, it has gained widespread acceptance and contributed significantly to the economies of many nations. the capability to establish regional and local supply chains is fundamental to the societal significance of industrial hemp as a raw material. there are two main drivers that promote regional distribution networks. first, because of their low density, bales of farmed hemp stalks are expensive to ship. second, different climates and soil types produce different results when growing cannabis. there is an incentive for processing and manufacturing hemp close to its source farms because of the economic benefits associated with doing so. the economic worth of regional produce increases as it is traded on an international or national level. when compared to shipping raw resources to distant sites for processing, producing higher-value goods and materials locally yields better economic benefits for the community's farmers and local manufacturers (wagner et al., 2022). these motivators promote social sustainability by keeping money in the area. despite encouraging findings from preliminary research, determining the social sustainability of the cannabis plant as a renewable industrial raw material is still in its beginning, and more study is needed to improve quantify, and evaluate the effects of cultivating and producing industrial hemp and processing hemp-based products. industrial hemp and sustainable development goals the 17 sustainable development goals (sdgs) of the united nations (un) aim to end poverty, improve health and education, decrease inequalities, safeguard the environment, and boost economic growth by 2030 (raihan et al., 2023f). all 193 member states agreed to the sdgs, which include 169 targets and global indicators to guide national, state, and municipal government priorities and collaborations. sustainable growth balances current and future requirements (raihan & tuspekova, 2022h). many sdg indicators recur across targets because complex challenges like health, equity, and climate change demand multidisciplinary solutions. in a contentious political atmosphere, the sdgs are popular worldwide and offer a template for galvanizing local assets to transform the globe (raihan & tuspekova, 2022i). corporations, institutions, and non-governmental organizations are incorporating the sdgs into their business plans. hemp industrialization is transforming healthcare, agriculture, energy, banking, technology, policymaking, and more. the growing industrial hemp and marijuana sector is improving epilepsy, multiple sclerosis, chronic pain, post traumatic stress disorder, and other treatments globally. as an alternative crop for paper, textiles, plastics, construction materials, and other green technologies that regenerate biodiversity, the cannabis plant helps combat climate change. the global market potential for industrial hemp surpasses that of medical and recreational marijuana because of the wide range of applications associated with the cannabis plant. the adaptability of the cannabis plant is exemplified by its inclusion in the sdgs, which also contribute to dispelling misconceptions about the plant. the sdgs provide a framework for enhancing education, legislation, research, and partnerships to effectively promote hemp as a vital crop that offers multiple societal advantages. the manifold advantages of industrial hemp have led to the identification of 54 hemp-related sdg targets, aimed at enhancing multi-sectoral collaboration, research, and education on a global scale. the links of hemp across the sdgs are depicted in figure 13. global sustainability research global scientific research 16 figure 13. the association of industrial hemp with the sdgs. no poverty (sdg 1) hemp has been recognized for its agricultural and sustainable food/energy potential for thousands of years across several continents and continues to be accepted by contemporary societies worldwide. wide-scale hemp growing, and related sectors may quickly eliminate large amounts of poverty at the national and local levels in three ways that support all other goals. first, dramatically reducing unsustainable energy and resource-based conflicts worldwide; second, increasing access to locally/regionally-grown healthy and nutritious foods for humans and livestock—hemp is naturally organic and superior to corn and soy; and third, creating a carbon-neutral farming, processing, manufacturing, and consumption infrastructure with huge economic and ecological benefits. global sustainability research global scientific research 17 cannabis plant cultivation worldwide could help resolve issues over fossil fuels. afghanistan, called the "graveyard of empires" for its history of thwarting energy-dependent colonial empires, is one example. it is also one of the poorest nations worldwide. cannabis plants could replace opium, lowering drug use. this market could also contribute to regional poverty since farmers make minimal revenues. cannabis plant cultivation nationwide benefits the population economically and reduces the power of extreme islamic organizations and invading empires. afghan farmers' desire to grow hemp dates back at least ten years, when global demand for hemp began to rise before the 2018 farm bill in the us. the u.n. office on drugs and crime reported a 63% increase in opium cultivation in afghanistan in 2017, hitting a record 328,000 hectares. a large fiber and seed-hemp crop in afghanistan would undoubtedly make the country more peaceful, productive, and rich. this would enable selfsufficiency through the consumption of nutritious hemp seed-derived food, relieving a large percentage of the people from conflict and scarcity. the same goes for impoverished southern asian and sub-saharan african communities. malawi, one of the poorest nations, is another example. the region can support hemp farming, new industries, and sustainable resource development. these nations might become major hemp producers with un support. cannabis plants could replace opium farms in afghanistan, tobacco plantations in kentucky, and the global demand for petroleum, valuable minerals, and petroleum-derived products. hemp planting at the national and corporate levels in industrialized nations like the us could minimize the need for historical incursion into afghanistan and other countries. hemp was the world's largest industrial crop until the late 19th century and hemp production was reduced mostly due to government mismanagement. over numerous decades, incorrect propaganda has shaped the current resource and energy environment, requiring significant efforts to repair the damage. zero hunger (sdg 2) hemp, as a sustainable and renewable resource, possesses the capacity to offer substantial quantities of nourishing and healthful food products. these include hemp seed protein, which exhibits variable potencies based on processing methods, as well as hemp seed milk, hemp seed oil, hemp hearts, and hemp seed flour. using these ingredients, individuals can create or enhance a wide range of culinary dishes, including bread and butter. the diet exhibits a commendable balance of nutrients and is deemed suitable for both human and cattle consumption, hence enhancing the nutritional value of animal-derived goods such as eggs and milk. the production of this food has the potential to yield cost savings and enhance nutritional value, thereby offering a viable solution in the face of climate change-induced disruptions to existing food supplies. hemp possesses the potential to significantly contribute to the mitigation of worldwide malnutrition and hunger rates. the plant exhibits a high degree of manageability and may be efficiently processed into food products with low reliance on external machinery, mostly decorticators. good health and well-being (sdg 3) the consumption of healthier food, particularly plant-based protein as a substitute for animal protein, the adoption of sustainable homes, the integration of hemp fiber in the textile industry to promote green practices, the reduction of resource-driven conflicts, and the stimulation of economic activity collectively contribute to the enhancement of human and animal health as well as overall well-being. every aspect of the cannabis plant, including the stalk, flower, seed, root, and stem, contributes to the enhancement of human and animal health and well-being. these components are free from any adverse side effects, psychoactive properties, or detrimental environmental consequences typically associated with traditional resources or their absence. hemp possesses unparalleled potential in reducing childhood death rates, surpassing any other available resource on the planet. research has demonstrated that cannabis possesses a range of therapeutic advantages, encompassing the alleviation of pain, mitigation of anxiety, and enhancement of sleep quality. consequently, the cannabis sector has the potential to global sustainability research global scientific research 18 contribute to sdg 3 through the production of cannabis-derived goods that are of superior quality and safety, thus enhancing individuals' health and overall well-being. within the framework of sdg 3, four targets pertaining to hemp and marijuana have been delineated. these targets encompass the prevention and treatment of substance misuse, ensuring access to safe and cheap vital medications, promoting research and development in the field of medicinal applications, and augmenting the allocation of financial resources and recruitment efforts within the health workforce. sdg 3.5 aims to address the issue of substance misuse through prevention and treatment measures. this statement underscores the necessity for expanded study on marijuana and hemp, since cannabis has potential alternative applications in comparison to opioid medicines, alcohol, and other addictive substances, with reduced risks of overdose and addiction. according to the study conducted by lucas et al. (2013), a significant proportion of participants, specifically 41%, reported using marijuana as a substitute for alcohol. additionally, 36% of participants indicated that they used marijuana as a substitute for illicit substances, while a substantial majority of 67% reported using cannabis as a substitute for prescription medicines. quality education (sdg 4) with regards to facilitating the provision of high-quality education to the global population, one significant advantage of hemp pertains to its ability to generate and allocate economic resources at the local, regional, and national scales. it is evident that subject to the discretion of nation-states and regional authorities, this economic development has the potential to enhance education on a broad scale. gender equality (sdg 5) hemp, particularly in the form of hempcrete, presents itself as a significantly lighter construction material compared to conventional options such as concrete or steel. when cultivating hemp, a significant amount of physical power is not necessary. when it comes to the processing of fiber and seed, it is necessary to employ machinery or rely on individuals with significant physical strength in places where mechanical assistance is limited. this is owing to the substantial muscular power and endurance demanded by such tasks. subsequently, there exists a comparable level of opportunity in many sectors such as textiles, house and building construction, food production, and an array of industrial industries including a multitude of consumer goods. a similar argument may be made about the establishment of extraction centers aimed at supplying communities with hemp extracts and dietary supplements specifically designed for female populations. hence, the hemp industry has the potential to promote gender equality through the creation of employment opportunities for individuals of men and women within the hemp sector. clean water and sanitation (sdg 6) certain varieties of cannabis plants are selectively developed for the purpose of phytoremediation, a technique that involves employing plants to extract contaminants from soil, water, or air. in the pursuit of achieving sdg 6, the cultivation of hemp presents a promising solution. this versatile plant possesses the unique ability to effectively address environmental contamination by virtue of its extensive root system. through this mechanism, the cannabis plant is capable of absorbing and sequestering heavy metals such as nickel and lead from the soil. consequently, it serves as a regenerative cleanup crop that can be cultivated in proximity to hazardous materials. hemp and cotton exhibit comparable characteristics; however, hemp seeds are more cost-effective and demand less water, fertilizer, and pesticides. consequently, this leads to a substantial reduction of 77% in agricultural production costs, promoting the achievement of sdg 6.3, which aims to reduce pollution, as well as sdg 6.4, global sustainability research global scientific research 19 which seeks to enhance water-use efficiency across various sectors. in addition, diets based on hemp seeds would reduce the environmental impact of human waste and animal dung on sewage systems. affordable and clean energy (sdg 7) the primary benefit of industrial hemp resides in its capacity to generate carbon-neutral ethanol and biodiesel derived from hemp seeds. the application of hemp biofuel possesses the capacity to substantially diminish the carbon emissions linked to human endeavors (raihan et al., 2022d), all the while offering accessible and environmentally friendly energy sources. hence, the utilization of hemp biofuel holds significant promise in enhancing energy efficiency, mitigating energy crises, and addressing environmental pollution concerns by substituting fossil fuels and thereby reducing emissions. decent work and economic growth (sdg 8) the hemp supply chain in the 21st century is extensive and has yet to be fully investigated. it encompasses various stages, including large-scale farming, initial retting, advanced processing, and manufacturing of numerous consumer-based products. additionally, the cannabis plant has the potential for food supply, energy production, and livestock feed, which could reduce the need to clear rainforests. consequently, the cultivation and utilization of hemp have the potential to generate a substantial number of environmentally sustainable manufacturing employment across both developing and industrialized nations. the legalization of the cannabis plant has the potential to enable governments to harness hemp as a means of generating a substantial number of employment opportunities, thus fostering the development of numerous sectors within the global economy. sdg 8 can be accomplished by establishing legal and controlled markets for cannabis, facilitating job creation, and tax generation, and fostering entrepreneurial prospects for small-scale enterprises. the legalization of hemp production in thailand has engendered novel prospects for farmers, given the versatile applications of hemp in several industries, including health and wellness, textiles, paper, and construction materials. through the cultivation of hemp, local farmers have the opportunity to enhance the diversity of their crop portfolio, augment their revenue, and make a valuable contribution to the overall economic growth of the nation. industries, innovation, and infrastructure (sdg 9) hemp possesses the potential to serve as a raw material for the production of more than 20,000 consumer goods. moreover, the transition from traditional petroleum-derived commodities such as wood and plastic to hemp is poised to give rise to a profoundly transformative era. in the context of developing nations, the utilization of a highly adaptable multi-crop like the cannabis plant holds the potential to yield a wide range of essential resources such as housing, clothing, medicine, and construction materials during the initial phases. despite the federal legalization of industrial hemp in the united states, a significant number of prominent firms, banks, and credit unions are hesitant to involve themselves with this plant. this reluctance stems from the ambiguous banking regulations and potential tax consequences associated with engaging in activities related to industrial hemp. sdg 9.3, which pertains to the target of enhancing access to financial services, emphasizes the necessity of implementing appropriate measures to facilitate the establishment of the legal hemp business. furthermore, the hemp and cannabis sectors have the potential to contribute to sdg 9 by fostering advancements in various aspects including cannabis production, product innovation, applications of cannabis, and distribution. this phenomenon has the potential to propel technological progress and generate novel prospects for both enterprises and individuals. the cannabis sector in thailand has garnered interest from international companies, leading to foreign investments in the nation. this influx of investments has not only generated employment possibilities but has also contributed to the overall economic growth and potential of the country. the projected global sustainability research global scientific research 20 growth rate of thailand's cannabis industry is estimated to be approximately 15% per year from 2023 to 2025. it is anticipated that the market value will potentially reach 1.17 billion usd by the year 2025. reduced inequalities (sdg 10) hemp, as a resource, confers empowerment upon individuals due to its environmentally friendly nature, costeffectiveness, ease of utilization, and ability to offer equitable opportunities. sdg 10 provides a robust framework for effectively mobilizing resources and establishing the necessary infrastructure for the development of the hemp industry, thereby promoting and advancing equality. the two specific targets outlined under sdg 10 are as follows: target 10.1 focuses on the objective of achieving income growth, while target 10.2 aims to promote social, economic, and political inclusiveness. in section 10.3, the target is to abolish laws that promote discrimination. in section 10.4, the aim is to establish fiscal, wage, and social protection measures that can facilitate the utilization of hemp's potential to address inequality issues and include comprehensive solutions into policies, programs, and partnerships involving multiple sectors. sustainable cities and communities (sdg 11) the utilization of hemp-based construction materials has the potential to contribute to the development of sustainable cities and communities. hempcrete bricks are characterized by their reduced weight compared to conventional cinder blocks and their exceptional durability, enabling them to endure for extended periods of time. without considering any other factors related to the adoption of hempcrete, it can be argued that its implementation alone has the potential to significantly enhance the health, cleanliness, and sustainability of cities and communities. in addition, the growth of the cannabis plant has the capacity to sequester carbon, presenting the possibility of obtaining carbon credits. furthermore, the establishment of legalized and well-regulated markets for cannabis has the potential to contribute to a decrease in crime rates and foster the creation of safer and more stable communities. responsible consumption and production (sdg 12) the initiation of responsible consumption can be attributed to the utilization of the cannabis plant. hemp possesses the potential to significantly influence both the environment and human society due to its multifaceted applications as a food source, textile material, energy provider, construction resource, and constituent of biodegradable products. the broad adoption of major consumer and industrial markets has the potential to significantly mitigate economic, environmental, and social problems associated with hemp. the production of hemp products, encompassing various components such as seeds, stalks, and flower-based extracts, can be effectively achieved using carbon-neutral and environmentally sustainable methods. the implementation of this practice is currently underway on a limited scale globally. sdg 12 encompasses various targets, including the promotion of sustainable production techniques (sdg 12.1), which necessitates the adoption of corresponding policies by enterprises (sdg 12.6) and the reduction of waste (sdg 12.5). hemp offers a viable means of fostering a more environmentally sustainable economy. hence, it is imperative for governments, academia, and corporate partners to collaborate and engage in technological advancements to facilitate the industrialization of hemp. climate action (sdg 13) the hemp industry has the potential to contribute to the achievement of sdg 13 by adopting sustainable and environmentally friendly practices in their production processes. this can be accomplished through the global sustainability research global scientific research 21 implementation of organic farming methods and the reduction of water and energy consumption, particularly when compared to the cultivation of alternative crops like cotton. furthermore, it is imperative for the industry to actively support and invest in research and development endeavors aimed at the creation of novel technologies capable of effectively curbing carbon emissions and mitigating the adverse consequences of climate change (raihan, 2023i). the cannabis plant has been found to contribute to mitigating the adverse effects of global warming and climate change by engaging in carbon sequestration, mitigating desertification, substituting fossil fuels with biofuel derived from hemp, and curbing deforestation to accommodate the growing agricultural needs to meet societal demands for food, fiber, and other commodities. life below water (sdg 14) the integration of the hemp supply chain has several beneficial outcomes, including reduced reliance on fish protein and fish oil aminos, coastal revitalization, diminished plastic pollution in oceans, and decreased petroleum use. the cannabis plant has the potential to significantly mitigate the emission of anthropogenic carbon dioxide into the atmosphere, as well as lessen the discharge of detrimental pollutants into the ocean resulting from agricultural practices such as cotton cultivation, deforestation, topsoil degradation, livestock farming, and other agricultural activities. the utilization of hemp-based biodegradable products has the potential to mitigate marine pollution and safeguard underwater biodiversity through the substitution of plastic materials. hemp has the potential to serve as a substitute for petroleum-based energy and its derivative products in the context of offshore drilling. life on land (sdg 15) the hemp industry contributes to environmental conservation efforts. cannabis plant, as a regenerative crop, possesses the capacity to rebuild soil organic matter and facilitate the restoration of deteriorated soil. this characteristic aligns with the targets outlined in sdg 15.3, which aims to rehabilitate soil and land that has undergone degradation. certain varieties of cannabis plants are selectively developed for the purpose of phytoremediation, a technique that involves employing plants to extract contaminants from soil, water, or air. cannabis plant possesses extensive root systems that effectively infiltrate the soil, facilitating the absorption of heavy metals such as nickel and lead. consequently, the cannabis plant serves as a regenerative crop capable of remediating contaminated areas, even when cultivated in proximity to hazardous substances. furthermore, the cannabis plant relies solely on wind for pollination and exhibits a notable capacity for generating a substantial quantity of pollen. this characteristic contributes to the establishment of an ecosystem that is very appealing to various bee species, which plays a vital role in promoting sustainable agricultural practices (o'brien & arathi, 2019). although the cannabis plant does not generate nectar, its blooms, which are abundant in pollen, contribute to the ecological significance of the cannabis plant as a crop. hemp, as a sustainable crop, exhibits the advantageous characteristic of necessitating minimum water usage, positioning it as an ecologically conscious substitute for conventional crops. hemp has the capacity to yield three times more metric tons than cotton, aligning with the target of sdg 15.3, which aims to restore life on land (schumacher et al., 2020). in addition, the cultivation of the cannabis plant has the potential to contribute to the preservation of wildlife biodiversity through its ability to mitigate unlawful poaching and hunting. this is due to the economic incentives derived from hemp cultivation, which divert the attention of poachers and hunters away from capturing rare and endangered animals. peace, justice, and strong institutions (sdg 16) global sustainability research global scientific research 22 the implementation of a program aimed at releasing individuals convicted of minor drug offenses from incarceration and integrating them into various sectors of the emerging hemp industry can perhaps contribute to the cessation of the worldwide campaign against illicit narcotics. these equity programs can be improved by integrating sdg targets 4.4: relevant skills for employment and entrepreneurship; sdg 4.5: decent work; sdg 8.3: job creation and entrepreneurship; sdg 11.a: strengthen national and regional development planning, and sdg 16.6: develop accountable and transparent institutions at all levels. the governments can also create hemp education programs for everyone, especially at-risk youth around how hemp can be used to day-by-day build a better future for all intelligent life on earth! furthermore, sdg 16.6 targets the development of accountable and transparent institutions at all levels. the hemp industry has the potential to contribute to the achievement of this objective by establishing diverse industries and organizations with several purposes, for example: hemp agronomics and farming hemp fiber applications in the automotive industry hemp biofuel applications throughout human society hemp business entrepreneurship hemp medicine and cannabinoid-based science hemp fiber applications in residential and commercial construction hemp food, nutrition, and herbal supplementation hemp bioplastic applications hemp as part of societal digital transformation technologies hemp musical instruments and spaceship components partnerships for the goals (sdg 17) various stakeholders, including farmers, entrepreneurs, startups, corporations, politicians, ngos, and local businesses, derive advantages from the utilization of hemp. sdg 17 outlines a strategic framework for harnessing the untapped potential of hemp and sets specific objectives to be achieved. sdg 17.14 emphasizes the need to strengthen policy coherence, while sdg 17.16 highlights the importance of establishing multi-stakeholder partnerships. additionally, sdg 17.17 underscores the significance of successful collaborations between the public sector, commercial sector, and civil society. these three targets provide valuable frameworks for exploring potential avenues to expand the industrialization of hemp. the integration of the 54 sdgs into the business plans of the industrial hemp and cannabis industry is recommended. this industry, being in its early stages, could actively participate in shaping collaborations across several sectors and contribute to the advancement of sustainability. conclusion this review study delves into the exploration of the potential and historical magnitude of the cannabis plant in human culture. additionally, this study illustrates the associations of the cannabis plant with the sdgs. using the cannabis plant as a renewable raw material, this study concluded that hemp has the potential to positively improve product sustainability, which has contributed to its rapid rise in popularity. many people admire the cannabis plant for its many benefits, including its compatibility with nature, its potential as an economic venture for local business owners, and its usefulness as a cover crop for small-scale farms. the majority of the study's findings on hemp's sustainability related to its ecological effects, followed by its economic impact. however, the social repercussions and social sustainability are poorly understood. this may be because research methods for assessing societal effects in terms of sustainability and life cycle assessment (lca) are still developing. however, global sustainability research global scientific research 23 new research into circular economies is beginning to consider the societal effects of these systems alongside the environmental and financial ones. in addition, the future demand for the cannabis plant will be determined by the pricing of hemp products, which in turn will be determined by customers' perceptions of the health and environmental benefits of using hemp products. research potential exists in these areas because neither a worldwide organization nor the federal government currently gathers worldwide information on the cultivation of hemp or its impact. the cannabis plant has a lot of potential in terms of sustainability, despite the current gaps, because it naturally fits into every aspect of sustainability and sdgs. as such, it satisfies the demand for a sustainable raw material alternative and provides a possible response to the critical climate problem. the full potential of this extremely promising multi-purpose crop cannot be realized without more investigation into appropriate agronomic production practices for greater productivity and sustainability. declaration acknowledgment: the authors

waste reduction; conservation; environmental health; systematic literature review; sustainability introduction environmental health concerns have increasingly captured the attention of researchers, policymakers, and the public as they become more pronounced in the face of modern challenges. according to the world health organization (who, 2021), environmental factors contribute to approximately 13 million deaths annually, highlighting the urgent need for effective interventions to address environmental management. poor air quality, contaminated water supplies, and hazardous waste are significant contributors to this crisis, leading to a myriad of health problems such as respiratory diseases, cardiovascular issues, and vector-borne illnesses (ren et al., 2021). vulnerable populations, including children, the elderly, and low-income communities, are particularly at risk, as they often reside in areas disproportionately affected by environmental hazards (levy et al., 2016). the implications of environmental health extend beyond immediate physical health effects; they also affect mental well-being, social equity, and economic stability. the increasing frequency of extreme weather events, largely global sustainability research global scientific research 108 attributed to climate change, further exacerbates these health concerns by displacing communities and straining healthcare systems (reid et al., 2016). as a result, addressing environmental health has become a multi-faceted challenge that requires a comprehensive understanding of the interconnectedness of human health and ecological systems. recycling, waste reduction, and conservation are critical strategies for mitigating environmental health issues and promoting sustainability. recycling has been shown to significantly reduce the demand for raw material extraction, which in turn conserves natural resources and minimizes habitat destruction (epa, 2021). for instance, recycling aluminum saves up to 95% of the energy required to produce new aluminum from bauxite ore, demonstrating the profound impact that recycling can have on energy conservation and emissions reduction (u.s. department of energy, 2020). furthermore, waste reduction initiatives not only decrease the volume of waste sent to landfills but also promote resource efficiency, thereby lowering greenhouse gas emissions associated with waste disposal (kaza et al., 2018). effective waste management practices can also lead to economic benefits, such as job creation in recycling and composting industries. conservation efforts, such as protecting biodiversity and natural habitats, are essential for maintaining ecosystem services that directly impact human health. healthy ecosystems provide vital services, including clean air and water, food security, and climate regulation (teeb, 2010). for example, wetlands act as natural filters for pollutants, while forests sequester carbon dioxide, thereby contributing to climate change mitigation. as biodiversity declines, the resilience of ecosystems diminishes, leading to increased vulnerability to environmental changes and health risks. the primary objective of this study is to explore and synthesize existing literature on strategies for promoting recycling, waste reduction, and conservation efforts and their impact on improving environmental health. by identifying effective interventions, this research aims to provide insights for policymakers, community leaders, and individuals to foster a more sustainable and health-oriented approach to environmental management. the study will employ a systematic literature review to assess the current state of knowledge, identifying gaps and opportunities for future research. ultimately, the findings are intended to support the development of comprehensive strategies that integrate environmental health considerations into broader sustainability efforts. literature review the literature on recycling, waste reduction, and conservation efforts has grown significantly over the past few decades, reflecting an increasing awareness of the environmental health crisis. this review synthesizes key studies in these areas, analyzes the impact of conservation efforts on environmental health, and identifies gaps in the existing literature that warrant further exploration. summary of key studies on recycling and waste reduction recycling has been widely recognized as a critical strategy for reducing waste and promoting sustainability. table 1, illustrates numerous studies that documented the environmental benefits of recycling, particularly in terms of resource conservation and energy savings. for instance, a study by the u.s. environmental protection agency (epa) (2021) found that recycling and composting prevented the release of 186 million metric tons of carbon dioxide equivalent into the air in 2018, equivalent to the annual emissions of 39 million cars. this illustrates the substantial impact recycling can have on greenhouse gas emissions. research by kaza et al. (2018) highlights the global disparities in recycling practices, emphasizing that while developed countries often have well-established recycling systems, many developing nations struggle with inadequate infrastructure and public awareness. their report, *what a waste 2.0*, provides a comprehensive overview of solid waste management practices across various countries, demonstrating that effective recycling programs can significantly mitigate waste generation and environmental degradation. they note that countries with higher recycling rates often implement robust educational campaigns and government regulations to encourage public participation. global sustainability research global scientific research 109 table 1. related studies on recycling, waste reduction and conservation sn focus focus country/region source 1 this study examines the pro-recycling attitudes of a community in greece and discusses strategies for designing effective recycling schemes that enhance public acceptance. pro-recycling attitudes of a community in greece greece (koutalakis & koutouki, 2023) 2 this journal features peer-reviewed articles focusing on various aspects of recycling, conservation, and resource management, providing insights into current research and practices. focuses on global circular economy practices not specified; focuses on global circular economy practices (rcr, 2024). 3 this research highlights the complexities of recycling information and its impact on public participation in waste management schemes, advocating for a holistic approach to information dissemination. conducted in an urban area not specified (miller & smith (2022) 4 this qualitative study explores the contextual and psychological factors influencing recycling behaviors, particularly regarding plastic packaging, and suggests strategies to improve participation. designing a recycling scheme for public acceptance. not specified, global plastic recycling efforts (thompson & moore, 2023) 5 this report outlines the progress and challenges in implementing the 7th environment action programme, focusing on environmental health and sustainability initiatives. implementation of environmental action programs. european union (european parliament, 2018) 6 this guide discusses the importance of recycling as a means to combat climate change and pollution, emphasizing its role in improving environmental health. the organization operates primarily in the united states. not specified (move for hunger, 2023) 7 this document outlines new programs developed by the epa to enhance recycling education and outreach, as mandated by the bipartisan infrastructure law. enhance recycling education and outreach. united states (u.s. environmental protection agency, 2021) 8 this open-access journal publishes research on circular economy practices, recycling, and waste utilization, contributing to the discourse on environmental conservation. the journal covers global recycling efforts. not specified (resources, conservation & recycling advances, 2024) 9 this study investigates the effectiveness of community-based initiatives in enhancing recycling rates and reducing waste, providing a detailed case study analysis. community-based initiatives in promoting recycling and waste reduction. not specified (chen & zhang, 2023) global sustainability research global scientific research 110 10 this research presents an experimental study on the impact of behavioral nudges in encouraging proper waste separation and recycling among residents in urban areas. behavioral nudges and recycling. not specified (klein & tatum, 2024) 11 this review article examines various waste reduction strategies implemented in urban settings, assessing their effectiveness and providing recommendations for policymakers. focuses on urban environments, in a latin american context. not specified (lópez & torres, 2022) 12 this meta-analysis explores the relationship between corporate social responsibility initiatives and consumer recycling behaviors, highlighting effective strategies. the study is likely relevant to various urban contexts. not specified (mason & granger, 2023) 13 this systematic review evaluates various educational interventions aimed at promoting recycling and their effectiveness in different demographics. educational interventions aimed at promoting recycling vietnam as indicated by the authors' affiliations.

(2020) investigates the role of public perception in recycling behavior. their findings indicate that individuals are more likely to recycle when they perceive a personal responsibility for environmental stewardship. furthermore, the study highlights the importance of convenience and accessibility in recycling programs, suggesting that communities that provide easily accessible recycling options experience higher participation rates. these insights are critical for designing effective waste reduction campaigns that resonate with target audiences. additionally, the role of legislation in promoting recycling is emphasized in the work of d'amato et al. (2021), who argue that the implementation of policies such as extended producer responsibility (epr) can significantly increase recycling rates. epr policies require manufacturers to take responsibility for the entire lifecycle of their products, including post-consumer waste. their research shows that countries with epr policies have achieved higher recycling rates and reduced waste generation compared to those without such regulations. analysis of conservation efforts and their impact on environmental health conservation efforts play a vital role in enhancing environmental health by preserving biodiversity, protecting ecosystems, and mitigating climate change. numerous studies have highlighted the interdependence of healthy ecosystems and human health. for instance, the studies by abdullah & abdul rahman (2023), bahl et al. (2020), and barbosa & lacerda (2023) provide valuable insights into various aspects of waste management and recycling initiatives. while they share a common goal of promoting sustainable practices, they differ in their focus areas, methodologies, and findings. likewise, the studies by huang & yu (2022), jiang et al. (2022), jiang & zhao (2024), and klein & tatum (2024) provide diverse insights into waste management behaviors, particularly focusing on waste separation, composting initiatives, eco-labeling, and behavioral nudges. each study contributes to understanding how different factors influence recycling and waste management practices. moreover, the global sustainability research global scientific research 113 millennium ecosystem assessment (2005) presents a comprehensive analysis of how ecosystem services, such as clean water, air purification, and nutrient cycling, directly contribute to human well-being. the report emphasizes that the degradation of these services due to habitat loss and pollution can lead to detrimental health outcomes. a study by bendor et al. (2015) further underscores the importance of conservation for public health by demonstrating the economic value of ecosystem services. their research reveals that investing in ecosystem restoration can yield significant returns in terms of health benefits, including reduced healthcare costs associated with pollution-related illnesses. the authors argue that integrating conservation efforts into public health policies can create a synergistic effect, benefiting both ecological integrity and human health. additionally, the role of community-based conservation initiatives has been explored in the literature. a study by pretty et al. (2013) examines how local engagement in conservation efforts can enhance ecological sustainability and improve community health outcomes. the authors argue that involving communities in decision-making processes fosters a sense of ownership and responsibility, leading to more effective conservation practices. their findings suggest that community-driven initiatives can address local environmental issues while simultaneously promoting public health. identification of gaps in the existing literature despite the wealth of research on recycling, waste reduction, and conservation, several gaps remain in the literature that warrant further investigation. one significant gap is the need for longitudinal studies that assess the long-term impacts of recycling and waste reduction initiatives on environmental health. for the purpose of this study relevant literature were compared and contrasted the findings of several studies focused on recycling behaviors, barriers, and strategies for effective waste management. the selected studies provide insights into various factors influencing recycling practices, including community engagement, socio-demographic influences, and the role of technology. most existing studies focus on short-term outcomes, making it difficult to draw definitive conclusions about the sustained effectiveness of these interventions. another gap is the limited exploration of the social and behavioral factors that influence recycling and conservation practices. while studies like those by zhang et al. (2020) have begun to address these issues, more research is needed to understand the complexities of human behavior in relation to environmental stewardship. investigating the psychological, cultural, and socio-economic factors that affect recycling participation could provide valuable insights for designing targeted interventions. furthermore, there is a need for more comprehensive studies that examine the intersection of waste management, recycling, and public health. while some research has explored the health benefits of conservation (bendor et al., 2015), the direct links between waste reduction practices and health outcomes remain under-explored. understanding how effective waste management can contribute to improved public health outcomes is critical for justifying investments in recycling and conservation initiatives. lastly, the role of emerging technologies in enhancing recycling and conservation efforts has not been sufficiently addressed in the literature. with advancements in digital platforms, artificial intelligence, and waste management technologies, there is an opportunity to investigate how these innovations can optimize recycling processes and promote more effective waste reduction strategies. ren, nie, & ming (2021) present an optimization model for sports goods recycling management based on the internet of things (iot). their research demonstrates how technology can streamline recycling processes, making it easier for consumers to participate in recycling programs. zhang & liu (2023) review innovative technologies for waste reduction, emphasizing the potential of smart waste management systems to enhance recycling efficiency. they argue that integrating technology into waste management can lead to significant improvements in recycling rates. global sustainability research global scientific research 114 methodology this study employs a systematic literature review (slr) process to comprehensively analyze existing research on recycling, waste reduction, and conservation efforts in relation to environmental health. the slr methodology involves a structured approach to identify, evaluate, and synthesize relevant literature systematically, minimizing bias and enhancing the reliability of findings (liberati et al., 2009). explanation of the review process the slr process began with the formulation of a clear research question aimed at understanding the effectiveness of various strategies for promoting recycling, waste reduction, and conservation. a comprehensive search strategy was developed, utilizing multiple databases, including pubmed, scopus, web of science, and google scholar. search terms included combinations of keywords such as “recycling,” “waste reduction,” “conservation,” and “environmental health.” the search was limited to peer-reviewed articles published in english between 2000 and 2023 to ensure the inclusion of recent and relevant studies. criteria for study selection and inclusion the inclusion criteria for selecting studies encompassed empirical research that specifically addressed the impact of recycling, waste reduction, and conservation efforts on environmental health outcomes. studies were included if they utilized quantitative, qualitative, or mixed-methods approaches and provided clear data on the effectiveness of the interventions. articles that focused solely on theoretical discussions or lacked empirical evidence were excluded. additionally, the studies focused on research in various countries were considered as illustrated in table 1 to capture a diverse range of experiences and practices. data extraction and synthesis methods data extraction involved systematically recording key information from each selected study, including authors, year of publication, study design, sample size, intervention details, and key findings. this information was organized in a structured spreadsheet for easy comparison and synthesis. the synthesis of data was conducted using thematic analysis to identify common themes, patterns, and gaps across the literature. this approach facilitated a comprehensive understanding of the effectiveness of different strategies in promoting sustainability and improving environmental health outcomes. results and discussion the systematic literature review (slr) yielded a total of 36 relevant studies that met the inclusion criteria, with findings spanning various geographical regions and contexts. the studies encompassed a range of methodologies, including quantitative, qualitative, and mixed-methods approaches. the analysis revealed several key themes regarding the effectiveness of recycling, waste reduction, and conservation efforts, as well as common barriers to implementation and recommendations for policy and community practices. effectiveness of recycling programs: a significant number of studies indicated that well-structured recycling programs can lead to substantial increases in recycling rates and decreased landfill waste. for instance, research by bahl et al. (2020) demonstrated that cities with comprehensive recycling programs saw a 20-30% increase in recycling rates over five years, compared to those without such programs. additionally, educational campaigns were found to enhance public awareness and participation in recycling initiatives, as highlighted by a metaanalysis conducted by schneider et al. (2021), which reported that targeted outreach efforts could increase recycling rates by up to 40%. global sustainability research global scientific research 115 waste reduction initiatives: the review also identified successful waste reduction initiatives, particularly those that focused on source reduction and community engagement. a study by jiang et al. (2022) found that implementing food waste reduction programs in urban areas resulted in a 15% decrease in organic waste sent to landfills. the study concluded that programs emphasizing community composting and food sharing significantly reduced waste and fostered a culture of sustainability. conservation efforts: conservation strategies were shown to have a positive impact on environmental health, with studies indicating that protecting natural habitats and promoting biodiversity can lead to improved ecosystem services. for example, a study by bendor et al. (2015) demonstrated that investments in ecosystem restoration yielded health benefits, including reduced respiratory illnesses related to air pollution and enhanced mental wellbeing associated with access to green spaces. behavioral factors: the literature highlighted the importance of understanding behavioral factors influencing recycling and waste reduction. studies by zhang et al. (2020) and kaza et al. (2018) emphasized that public perceptions of recycling responsibilities, convenience, and social norms significantly affected participation rates. behavioral nudges, such as the placement of recycling bins in strategic locations, were effective in increasing recycling behaviors. abdullah & abdul rahman (2023) emphasize community engagement in waste reduction initiatives in urban malaysia. their findings highlight the importance of local participation and collaboration in enhancing the effectiveness of waste management strategies. they argue that community-driven approaches lead to greater awareness and commitment to waste reduction efforts. in contrast, bahl et al. (2020) focus on assessing the impact of recycling programs on urban waste management. their study employs quantitative methods to evaluate the effectiveness of existing recycling initiatives, revealing that structured programs significantly improve recycling rates and reduce landfill waste. they suggest that well-designed recycling programs are crucial for effective urban waste management. on the other hand, barbosa & lacerda (2023) explore the intersection of green marketing strategies and consumer recycling behavior. their empirical study indicates that targeted marketing campaigns can positively influence consumer attitudes towards recycling, leading to increased participation in recycling programs. they emphasize the role of effective communication in shaping consumer behavior. patel & khan (2024) explore barriers to recycling in multi-family housing, identifying challenges such as lack of space for recycling bins, insufficient information on recycling practices, and social norms that discourage participation. their qualitative study highlights the need for tailored solutions in residential settings to enhance recycling rates. thompson & moore (2023) focus on barriers and facilitators to recycling plastics, emphasizing psychological factors such as perceived inconvenience and lack of knowledge. they suggest that addressing these psychological barriers through targeted education and awareness campaigns can significantly improve recycling behaviors. meanwhile, perkins & smith (2024) discuss sustainable waste management strategies that enhance recycling through community partnerships. they argue that involving local communities in the design and implementation of recycling programs fosters a sense of ownership and responsibility, leading to higher participation rates. jiang, wang, & zhang (2022) assess community-based food waste reduction initiatives, specifically urban composting programs. their findings indicate that community involvement not only reduces food waste but also strengthens social ties and increases awareness about sustainable practices. moreover, santos & ferreira (2023) conduct a multi-country analysis of socio-demographic factors influencing recycling behavior. they find that age, education level, and income significantly affect individuals' recycling habits, suggesting that targeted interventions should consider these demographic variables to be effective. li & wang (2023) examine psychological and social factors affecting consumer behavior towards recycling. their study highlights the importance of social norms and peer influence, indicating that individuals are more likely to recycle if they global sustainability research global scientific research 116 perceive it as a common practice within their community. huang & yu (2022) conducted a field experiment in urban china to analyze behavioral patterns in waste separation. they found that specific interventions, such as providing clear instructions and feedback, significantly improved residents' waste separation behaviors. their study emphasizes the importance of understanding local contexts and tailoring strategies to enhance participation in waste management. klein & tatum (2024) also focus on behavioral nudges to improve waste separation. their experimental study demonstrates that simple nudges, such as visual cues and reminders, can effectively increase the rates of proper waste separation among participants. this suggests that behavioral insights can be leveraged to design more effective waste management strategies. on the other hand, jiang et al. (2022) assess the effectiveness of community-based food waste reduction initiatives, particularly urban composting programs. their findings indicate that these initiatives not only reduce food waste but also foster community engagement and awareness about waste management. they highlight the role of community involvement in achieving sustainable waste reduction goals. moreover, jiang & zhao (2024) conduct a meta-analysis on the impact of eco-labeling on consumer recycling behavior. their analysis reveals that eco-labels significantly influence consumer choices, leading to increased recycling rates. they argue that clear and credible eco-labeling can enhance consumer awareness and motivate environmentally friendly behaviors. key findings and implications abdullah & abdul rahman stress that engaging the community is essential for the success of waste reduction initiatives. their qualitative approach reveals that local knowledge and involvement can lead to more tailored and effective waste management solutions. while, bahl et al. provide evidence that structured recycling programs yield measurable improvements in waste management outcomes. their findings suggest that municipalities should invest in developing and promoting such programs to enhance recycling rates. additionally, barbosa & lacerda highlight the potential of green marketing to drive consumer behavior towards recycling. their results suggest that businesses and policymakers should leverage marketing strategies to foster a culture of recycling among consumers. in a nutshell, abdullah & abdul rahman (2023) focus on the importance of community engagement, bahl et al. (2020) provide a quantitative assessment of recycling programs, and barbosa & lacerda (2023) examine the role of marketing in influencing consumer behavior. together, these studies underscore the multifaceted approach needed to enhance waste management and recycling efforts, suggesting that a combination of community involvement, effective programs, and strategic marketing can lead to more sustainable outcomes. huang & yu emphasize the need for tailored interventions that consider local behavioral patterns to effectively promote waste separation. their findings suggest that understanding the specific context of urban residents is crucial for designing successful waste management campaigns. additionally, klein & tatum's research supports the idea that behavioral nudges can be a powerful tool in enhancing waste separation practices. their results indicate that small changes in the environment can lead to significant improvements in recycling behaviors. furthermore, jiang et al. highlight the effectiveness of community-based initiatives in reducing food waste. their study suggests that involving the community in composting efforts not only addresses waste management challenges but also builds a sense of responsibility and awareness among residents. jiang & zhao's meta-analysis underscores the importance of eco-labeling as a strategy to influence consumer behavior positively. their findings suggest that effective labeling can serve as a catalyst for increased recycling participation. ultimately, the studies collectively illustrate the multifaceted nature of waste management and recycling behaviors. huang & yu (2022) and klein & tatum (2024) focus on behavioral interventions to improve waste separation, while jiang et al. (2022) emphasize community-based initiatives for food waste reduction. jiang & zhao (2024) provide insights into the role of eco-labeling in influencing consumer behavior. together, these findings highlight the importance global sustainability research global scientific research 117 of tailored strategies, community involvement, and effective communication in promoting sustainable waste management practices. summary of findings both patel & khan and thompson & moore identify psychological and logistical barriers to recycling, suggesting that education and tailored solutions are crucial for overcoming these challenges. while some studies by perkins & smith and jiang et al. highlight the importance of community involvement in enhancing recycling efforts, indicating that participatory approaches can lead to better outcomes. santos & ferreira and li & wang emphasize the role of socio-demographic characteristics in shaping recycling behaviors, suggesting that interventions should be customized based on these factors. likewise, the research by ren et al. and zhang & liu points to the potential of technology to improve recycling systems, making them more efficient and user-friendly. the studies collectively underscore the complexity of recycling behaviors and the multifaceted approaches needed to enhance waste management practices. by addressing barriers, fostering community engagement, considering sociodemographic influences, and leveraging technology, stakeholders can develop more effective recycling strategies that promote sustainable waste management. effective strategies and interventions the findings from the slr underscore several effective strategies and interventions that can enhance recycling, waste reduction, and conservation efforts. one of the most consistent themes across the literature is the effectiveness of education and awareness campaigns in promoting recycling and waste reduction behaviors. research shows that educational initiatives that inform individuals about the environmental benefits of recycling and provide clear instructions on how to recycle can significantly increase participation rates (schneider et al., 2021). for example, community workshops, school programs, and social media campaigns can effectively engage the public and foster a culture of sustainability. additionally, implementing incentive programs, such as reward systems for recycling, has proven effective in motivating individuals to participate. a study by kelleher et al. (2019) found that communities that offered financial incentives for recycling saw a marked increase in participation rates. similarly, coupon programs that provide discounts at local businesses for recycling efforts encourage community engagement and support local economies. moreover, the literature consistently highlights the importance of adequate infrastructure in facilitating recycling and waste reduction. research shows that providing easily accessible recycling bins and appropriate signage can significantly enhance participation rates (zhang et al., 2020). communities that invest in infrastructure improvements, such as centralized recycling centers and curbside pickup services, often experience higher recycling rates. furthermore, engaging communities in decision-making processes regarding waste management and conservation efforts fosters a sense of ownership and responsibility. studies indicate that community-driven initiatives, such as local clean-up events and neighborhood recycling competitions, can increase participation and strengthen community bonds (pretty et al., 2013). engaging local stakeholders in the development and implementation of recycling programs leads to tailored solutions that resonate with community needs. lastly, the role of policy and legislation in promoting recycling and waste reduction cannot be overstated. research by d’amato et al. (2021) indicates that countries with strong regulatory frameworks, such as extended producer responsibility (epr) policies, experience higher recycling rates and more effective waste management overall. policymakers play a crucial role in establishing clear guidelines, allocating resources, and incentivizing sustainable practices. global sustainability research global scientific research 118 consideration of barriers to recycling and waste reduction despite the identified effective strategies, several barriers hinder the successful implementation of recycling and waste reduction initiatives. one of the most significant barriers to effective recycling and waste reduction is the lack of awareness and understanding among the public. many individuals remain uninformed about what materials are recyclable, leading to contamination of recycling streams and reduced effectiveness of programs (kaza et al., 2018). the literature emphasizes the need for continuous education and outreach efforts to bridge this knowledge gap. another barrier is convenience and accessibility, convenience plays a critical role in recycling participation. research has shown that when recycling bins are not conveniently located or accessible, participation rates decline significantly (schneider et al., 2021). communities must ensure that recycling infrastructure is adequately available and that residents have easy access to recycling facilities. moreover, cultural attitudes and social norms can also pose barriers to recycling and waste reduction. in some communities, recycling may not be viewed as a social responsibility, leading to lower participation rates (zhang et al., 2020). addressing these cultural barriers requires tailored interventions that resonate with specific community values and beliefs. furthermore, economic factors can also impact the effectiveness of recycling and waste reduction initiatives. limited funding for recycling programs and infrastructure can hinder their development and sustainability. additionally, in low-income communities, individuals may prioritize immediate economic needs over environmental concerns (jiang et al., 2022). policymakers must consider these economic constraints when designing and implementing programs. implications for policy and community practices the findings from the slr carry important implications for policymakers and community leaders seeking to promote recycling, waste reduction, and conservation efforts. policymakers should prioritize the development and implementation of regulations that support recycling and waste reduction initiatives. this includes establishing epr policies that hold manufacturers accountable for the lifecycle of their products, as well as promoting comprehensive waste management strategies that include recycling, composting, and source reduction (d'amato et al., 2021). adequate funding and resource allocation are essential for the success of recycling and waste reduction programs. governments should invest in infrastructure improvements, educational campaigns, and incentive programs that facilitate participation. collaborating with non-profit organizations and businesses can also enhance resource availability and support community initiatives. engaging communities in the decisionmaking process and implementation of recycling initiatives can lead to more effective and sustainable outcomes. policymakers should involve local stakeholders in the development of programs that reflect community needs and values. this approach fosters a sense of ownership and encourages active participation in sustainability efforts (pretty et al., 2013). implementing behavioral interventions, such as nudges and social marketing campaigns, can effectively change public perceptions and behaviors related to recycling and waste reduction. research indicates that framing recycling as a social norm and utilizing positive reinforcement strategies can encourage individuals to adopt sustainable practices (zhang et al., 2020). continuous monitoring and evaluation of recycling and waste reduction programs are essential to assess their effectiveness and identify areas for improvement. policymakers should establish clear metrics to evaluate the success of initiatives, allowing for data-driven decision-making and adjustments as needed (kaza et al., 2018). conclusion this study has explored the critical intersection of recycling, waste reduction, and conservation efforts in relation to environmental health through a systematic literature review. key insights reveal that effective strategies such global sustainability research global scientific research 119 as education and awareness campaigns, infrastructure improvements, community engagement, and strong legislative support are essential for enhancing participation in recycling and waste reduction initiatives. the evidence suggests that comprehensive and tailored approaches can significantly improve recycling rates and mitigate the environmental health crisis. to optimize the efficacy of these initiatives, stakeholders—including policymakers, community leaders, and organizations—should prioritize collaborative efforts that foster community ownership and engagement. recommendations include the development of incentive programs that reward sustainable behaviors, increased investment in recycling infrastructure, and the implementation of educational outreach tailored to diverse community needs. policymakers should also consider adopting robust regulations such as extended producer responsibility (epr) to hold manufacturers accountable for their products' lifecycle, promoting a circular economy. furthermore, while this research has provided valuable insights, it also highlights the need for further exploration in this field. future research should focus on longitudinal studies that assess the long-term impacts of recycling and waste reduction initiatives on environmental health outcomes. additionally, investigations into the social and behavioral factors influencing recycling behaviors can provide deeper insights for designing effective interventions. finally, exploring the role of emerging technologies in enhancing recycling processes and community engagement could offer innovative solutions to current challenges. advancing recycling and waste reduction efforts is paramount for safeguarding environmental health. by implementing targeted strategies and fostering a culture of sustainability, stakeholders can contribute to a healthier planet for current and future generations. declaration acknowledgment: thanks to all authors of this paper for their valuable contributions. funding: no fund or grant is

chen qihao. email: 631356141@qq.com received: 15 january, 2025, accepted: 18 march, 2025, published: 21 march, 2025 abstract tourism has become a key driver of economic growth and regional development, yet its impact on economic disparities and sustainability remains underexplored. against the backdrop of global efforts to achieve sustainable development, this study investigates the role of tourism industry agglomeration in addressing regional economic disparities, with a focus on the moderating effects of transport and information infrastructure. using panel data from 31 chinese provinces and cities spanning 2004 to 2020, we integrate transport and information infrastructure into a research framework to examine the relationship between tourism industry agglomeration and regional economic disparities. through multiple econometric methods, we empirically analyze the influence of tourism industry concentration density on regional economic gaps and explore the underlying mechanisms. our findings indicate that tourism industry agglomeration significantly reduces regional economic disparities, while transport and information infrastructure play a crucial moderating role, albeit with regional and temporal heterogeneity. furthermore, the relationship between tourism agglomeration and economic disparities, as well as the role of infrastructure, exhibits nonlinear characteristics, suggesting complex interactions. importantly, the study underscores the potential of sustainable tourism practices in fostering longterm economic balance and environmental preservation, aligning with global sustainability goals. these insights provide valuable references for policymakers aiming to narrow economic gaps and promote coordinated regional development through sustainable tourism strategies. keywords: tourism cluster; economic gap; infrastructure development; moderating effect; threshold effect introduction as modernization progresses, the growing discrepancy in economic development between regions has become increasingly noticeable. in particular, china has demonstrated a marked concern for imbalanced regional development. in march 2021, the outline of the people’s republic of china 14th five-year plan for national economic and social development and long-range objectives for 2035 issued by the thirteenth national people’s congress, clearly emphasized the need to actively bridge the economic gap between regions. unraveling how to alleviate these economic disparities presents a significant challenge for china to achieve its goal of common prosperity. the tourism industry has emerged as a key driver of economic growth, stimulating global sustainability research global scientific research 38 consumer spending and creating job opportunities. according to the basic situation of the 2019 tourism market released by the ministry of culture and tourism, the tourism industry’s comprehensive contribution to the national economy reached 10.94 trillion yuan, with a contribution rate as high as 11.05%. furthermore, employment generated by the tourism industry and related sectors accounted for 10.31% of the total national employment, underscoring its pivotal role in propelling the national economy. however, the economic effects of tourism are often underestimated due to the increasing overlap between tourism activities and everyday life. this convergence has led scholars to overlook the potential of tourism in alleviating regional economic disparities. tourism industry agglomeration, characterized by the spatial concentration of tourism-related activities, is considered a dynamic form of spatial organization and a critical aspect of industry development (wang et al., 2020).yet, its impact on regional economic disparities remains underexplored. existing literature has largely ignored the role of transport and information infrastructure in the relationship between tourism and regional economic disparities. while studies have shown that transport and information infrastructure significantly influence both the tourism industry and regional economies, their moderating effects on the impact of tourism agglomeration on regional disparities have not been adequately addressed. (liu zhen et al., 2022; cheng yu et al., 2023; sun et al., 2019).this omission may lead to biased conclusions and an incomplete understanding of the mechanisms at play. additionally, previous studies have primarily relied on specialized or total tourism revenue indicators to measure tourism development, neglecting spatial disparities and the strong industry correlation inherent in tourism(li & zhang, 2023; wang & chen, 2023; smith & brown, 2024; garcia & lee, 2023). furthermore, there is a lack of empirical discussion on the heterogeneous impacts of tourism agglomeration and infrastructure on regional disparities. to address these gaps, this study investigates the impact of tourism industry agglomeration on regional economic disparities, incorporating transport and information infrastructure as moderating factors. using panel data from 31 chinese provinces and cities (2004–2020), the study aims to: (1) explore whether tourism agglomeration mitigates regional economic disparities; (2) examine the moderating effects of transport and information infrastructure, both individually and jointly, on this relationship; and (3) analyze the potential nonlinear characteristics of these effects. by measuring tourism agglomeration from a spatial perspective and considering the combined effects of infrastructure, this study provides a more comprehensive understanding of the mechanisms driving regional economic disparities. literature the impact of tourism industry agglomeration on regional economic disparities direct impact effects tourism industry agglomeration has direct effects on regional economic disparities. first, tourism activities generate direct income effects, as tourist expenditures during trips translate into local tourism revenues. the increased concentration of the regional tourism industry can further stimulate tourism income, thereby directly promoting economic growth in underdeveloped areas and alleviating regional economic disparities. second, tourism activities engender wealth-transfer effects. tourist activities involve interregional mobility due to the touristic flow effect, leading to wealth transfer and income redistribution between regions. this fosters economic development in tourism destinations (soukiazis et al., 2008). additionally, the income earned by tourism industry employees, when used to purchase goods for sustaining livelihoods, similarly generates wealth transfer and income redistribution, thereby promoting local economic development(wu,2011). consequently, the global sustainability research global scientific research 39 development of the tourism industry can expand both tourism demand and supply, thereby promoting wealth distribution and propelling local economic effects to narrow the economic gap with other regions. finally, the tourism industry exhibits industry-linkage effects. apart from tourism products, there are basic industries associated with obtaining these products, namely industries related to tourism, such as agriculture, animal husbandry, construction, and food manufacturing (wu,2012). demand for these industries can stimulate the development of corresponding industries, thereby driving economic growth. with the heightened level of tourism industry agglomeration, the increased demand for associated industries not only promotes the upgrading of the tourism industry chain, but also caters to dynamic changes and diversified tourism demands, thereby mitigating economic disparities with other regions. indirect impact effects tourism industry agglomeration indirectly influences regional economic disparities. first, interactions among laborers give rise to knowledge spillover effects (wang jiaying et al., 2021) . as the tourism industry develops, the increased number and higher professional standards of tourism industry workers can enhance knowledge spillover effects, thereby promoting innovation in tourism products and refining enterprise management practices. this fosters the competitiveness and attractiveness of tourism products, further propelling economic growth to alleviate regional economic disparities. second, as the level of tourism industry agglomeration increases, the demand for tourism activities also increases, leading to intensified competition among tourism products, thereby creating a competitive effect. competition serves as a significant driver of product innovation, fostering the enhancement of tourism product attractiveness and exerting a significant promotional effect on the economy, thus reducing economic disparities with other regions (wang et al., 2020) . finally, the tourism industry’s tourist flow effect, where multi-destination tourists may choose multiple destinations in one trip, leads to factor mobility effects. the development of the tourism industry has promoted increased demand, guiding underutilized or mismatched labor and capital resources to flow into the tourism industry. this further enhances product quality and meets the demands for tourism while promoting local economic development, thereby easing uneven development among regions. therefore, based on the aforementioned analysis, the following hypothesis is proposed: h1: tourism industry agglomeration has a negative impact on regional economic disparities. the influence mechanism of tourism industry agglomeration on regional economic disparities initially, the enhancement of local informatization and transport accessibility levels promotes the mobility and distribution efficiency of labor and capital resources (xie kai et al., 2023; wang chong et al., 2023) . this facilitates the rational allocation and utilization of idle, mismatched, or surplus resources, fostering the development of not only the tourism industry, but also related industries, thereby stimulating local economic effects and mitigating economic disparities with other regions. additionally, the improvement of local transport accessibility and reduction of information barriers alleviates the search and transport costs for tourists and labor, contributing to the rational utilization and development of tourism resources while reducing local tourism losses. this, in turn, fosters the development of local tourism and related industries, thereby mitigating regional economic disparities. lastly, the advancement of informatization and transport accessibility “compresses” time global sustainability research global scientific research 40 and space, thereby reducing the transport costs of tourism products and raw materials (huang et al., 2021) and fostering innovation in tourism products (ji et al., 2023) . this results in an upgrade of tourism products in terms of quality, variety, and price, enhancing their competitiveness and attractiveness to tourists, further promoting economic growth, and alleviating regional economic disparities. in conclusion, the advancement of regional transport or information infrastructure progressively breaks down “information barriers,” enhances transport convenience, and stimulates local tourism development, to a certain extent mitigating uneven economic development among regions. according to the new economic geography theory, industries undergoing spatial agglomeration are influenced by both centripetal and centrifugal forces (fujita et al., 2001) . given the interconnected and spatially cohesive nature of the tourism industry, its development is subject to the influence of both centripetal and centrifugal forces (wang et al., 2019) . when the level of transport or information infrastructure is low, constraints on local tourism development arise owing to inadequate transport connectivity or information accessibility. therefore, lower levels of informatization or transport convenience exert centrifugal force on local tourism development. additionally, in economically developed regions, the richness of tourism products, sophistication of infrastructure and tourism industry chains, abundance of resource reserves, and higher professional skills of the workforce make these areas more attractive to tourists, thus limiting the development of tourism in less economically developed regions. consequently, deficiencies in aspects such as tourism products, infrastructure, resource elements, and labor skills exert centrifugal forces on local tourism development. as the level of informatization or transport convenience increases, the gradual dismantling of the "digital divide" and enhanced transport accessibility significantly fosters local tourism development, thereby generating centripetal forces on local tourism development. in this context, the impact of tourism industry agglomeration on regional economic disparities is not simply a static and linear effect. instead, it is influenced by transport or information infrastructure and exhibits significant nonlinear characteristics. specifically, thresholds could be measured or defined based on the levels of information and transport infrastructure development, which determine whether the impact is more centripetal or centrifugal. the threshold effect refers to a phenomenon where a certain minimum level of input, effort, or exposure is required before a significant change, response, or outcome is observed. below this threshold, the effect may be negligible or non-existent, but once the threshold is crossed, the impact becomes noticeable and often increases rapidly. in conclusion, this study proposes the following hypothesis: h2-1: the impact of tourism industry agglomeration on regional economic disparities is negatively moderated by “information infrastructure,” exhibiting threshold characteristics. h2-2: the impact of tourism industry agglomeration on regional economic disparities is negatively moderated by “transport infrastructure,” which exhibits threshold characteristics. h2-3: the impact of tourism industry agglomeration on regional economic disparities is negatively moderated by “information and transport infrastructure,” exhibiting threshold characteristics. methodology model construction based on the theoretical analysis and research hypotheses, to explore the impact of tourism industry agglomeration on regional economic disparities and recognizing that neglecting individual effects, time effects, global sustainability research global scientific research 41 and the correlation between error terms and explanatory variables may lead to biased model estimates, this study adopts the two-way fixed effects model as the baseline regression model, formulated as follows: gap it =β 0 +β 1 tait+β 2 xit+μ it +εit (1) variable definitions: gap it : the level of regional economic disparities in province i at time t, measured by the gini coefficient of per capita gdp across prefecture-level cities or districts (unit: dimensionless). tait: the level of tourism industry agglomeration in province i at time t, measured by the spatial agglomeration density (unit: per square kilometer). xit: a vector of control variables for province i at time t (definitions provided in section 3.2.4). μ it :the individual fixed effect for province i at time t, capturing unobserved time-invariant characteristics. εit :the random disturbance term for province i at time t (unit: dimensionless). we choose the two-way fixed effects model over other alternatives such as pooled ols or random effects models for several reasons. first, it effectively controls for unobserved heterogeneity that may be correlated with the explanatory variables. by including both individual and time fixed effects, we can eliminate biases arising from time-invariant provincial characteristics and common temporal shocks. recent studies, such as chen and liu (2023), have employed spatial econometric models to address spatial dependencies in tourism agglomeration, while martinez and kim (2024) utilized dynamic panel data models to capture temporal dynamics. however, our approach focuses on controlling for unobserved heterogeneity and temporal shocks, which are critical for unbiased estimation in our context.second, the hausman test confirms that fixed effects are more appropriate for our dataset, suggesting that unobserved individual effects are correlated with the explanatory variables. lastly, this model provides a robust framework for analyzing the dynamic relationship between tourism industry agglomeration and regional economic disparities over time and across regions. furthermore, to verify whether the research hypotheses on the impact mechanism of tourism industry agglomeration on regional economic disparities hold, this study introduces moderating variables, including transport, information infrastructure, and the combination of transport and information infrastructure, into formula (1), as well as interaction terms between tourism industry agglomeration and the moderating variables. the specific model is as follows. gap it =β 0 +β 1 tait+β 2 mit+β 3 tait*mit+β 4 xit+μ it +εit (2) mit:moderating variables in province i at time t, representing transport, information infrastructure, and the combination of both. in recent years, research on tourism agglomeration and regional economic disparities has increased, but most studies have not fully considered the moderating role of infrastructure and its nonlinear characteristics. for example, zhang et al. (2023), in their study on the impact of tourism agglomeration on regional economic disparities, considered the linear moderating effect of a single type of infrastructure without introducing interaction terms or threshold models. in contrast, this study, by incorporating interaction terms and threshold models, can more comprehensively capture the complex relationship between tourism agglomeration and infrastructure. finally, to further verify whether the impact of tourism industry agglomeration on regional economic disparities exhibits non-linear relationships with "mit", we adopt transport, information infrastructure, and the combination of transport and information infrastructure as threshold variables to construct a threshold model. the model is expressed as follows: global sustainability research global scientific research 42 gap it =α0+β 1 tait*i(mit<γ 1 )+β 2 tait*i(γ 1 ≤mit< γ 2 )+⋯+β n tait*i(γ n-1 ≤mit<γ n )+β n+1 tait*i(mit≥γ n )+δxit + εit (3) γ 1 , γ 2 ,…, γ n : threshold values defining different intervals for the moderating variables. β 1 , β 2 , …, β n :the estimated coefficients for different threshold intervals. 𝐈(·) : indicator function, taking the value of 1 when the threshold variable is within a specific range, and 0 otherwise. additionally, wang and liu (2024) explored the moderating role of information infrastructure, but their model did not distinguish the effects across different threshold intervals, resulting in limited explanatory power for nonlinear relationships. the threshold model in this study, through a piecewise regression approach, reveals the nonlinear impact mechanisms of tourism agglomeration on regional economic disparities, providing more nuanced insights for policy formulation. variable construction dependent variable regional economic disparity (gap) follows the approach of wang qing et al. (2018) .this study measured using the gini coefficient of per capita gdp across prefecture-level cities or districts within each province or directly controlled municipality. the specific formula is as follows: gap it = 2 n ∑   n i=1 ixin+1 n (4) where: xi=y i / ∑  n i=1 y i ，and，xi<xi<xi<…<xn, “n” represents the number of regions. yi denotes the per capita gdp of each prefecture (or district). xirepresents the proportion of the per capita gdp of each city in the total per capita gdp of the province, arranged in ascending order. key explanatory variable tourism industry agglomeration (ta) follows the methodology of yang yong (2012). it is measured by the spatial agglomeration density of the tourism industry. specifically, it is calculated as the proportion of the total tourism industry revenue of each province and city to the total revenue of all studied provinces and cities, divided by the land area of each province and city. the formula is given by: tait= revenueit ∑ revenueit areait *100 (5) global sustainability research global scientific research 43 where tait denotes the spatial agglomeration density of the tourism industry in province i at time t, revenueit represents the total revenue of the tourism industry in province i at time t, and areait denotes the land area in province i at time t. where: tait: spatial agglomeration density of the tourism industry in province i at time t (unit: per square kilometer). revenueit: total tourism industry revenue in province i at time t. areait: land area of province i at time t moderating variables (1) information infrastructure (dig): we construct an index system for information infrastructure based on indicators such as fixed asset investment in information transmission computing, optical cable construction level, internet penetration rate, internet user proportion, mobile phone penetration rate, and postal and telecommunications business volume. the entropy method is used to measure the level of information infrastructure (zhao lei, 2013; sun li et al., 2021). (2) transport infrastructure (tra): we establish an index system for transport infrastructure using indicators such as road density, railway density, urban road area, and urban public transport vehicles. the entropy method is used to measure the level of transport infrastructure. (sun yu, 2019; zan xin, 2023). (3) transport and information infrastructure (fra): we combine the index systems of information infrastructure and transport infrastructure and measure the combined level using the entropy method. specific indicators are listed in table 1. table 1. index system of information and transport infrastructure primary indicators secondary indicators measurement criteria information infrastructure information transmission computer fixed asset investment amount of fixed asset investment in information transmission computing optical cable construction level length of long-haul optical cable/area internet penetration rate number of broadband internet access users/total population internet user proportion number of internet users/total population mobile phone penetration rate number of mobile phone users/total population postal and telecommunications business volume total volume of postal and telecommunications business/total population transport infrastructure road density length of roads/area railway density length of railways/area urban public transport vehicles public transport vehicles/total population urban road area urban road area/total population global sustainability research global scientific research 44 control variables (1) industrial structure upgrading: this variable measures the proportion of the total output value of the tertiary industry to that of the secondary industry. it reflects the resource allocation effects from the upgrading of industrial structure, which can impact regional economic disparities by influencing the transfer and agglomeration of production factors. following the approach of ding junsong et al. (2022) , this study uses the proportion of the total output value of the tertiary industry to that of the secondary industry to measure the level of industrial structure upgrading. (2) degree of government intervention: measured by the proportion of government fiscal expenditure to gdp, this variable captures the government's influence on regional development through. this study uses the proportion of government fiscal expenditure to gdp to represent the degree of government intervention, as proposed by lin yifu et al. (2013). (3) level of human capital: human capital can promote knowledge spillover effects, drive product innovation, and enhance product competitiveness, serving as a key factor influencing regional economic differentiation. following the approach of zhao lei et al. (2017), this study measured the level of human capital using the average years of education per capita. (4) level of foreign direct investment: capital investment significantly promotes industrial development and drives the economy. it also has an impact on the level of economic development among regions. referring to the approach of yanlong et al. (2020), this study measures the level of foreign direct investment using the proportion of foreign investment to gdp. table 2. descriptive statistics for key variables type name symbols observations mean standard deviation dependent variables regional economic disparities gap 527 0.2571 0.0766 independent variables tourism industry agglomeration ta 527 0.6229 1.7201 moderating variables information infrastructure dig 527 0.2386 0.1385 transport infrastructure tra 527 0.3445 0.1689 information and transport infrastructure fra 527 0.2679 0.1303 controlling variables foreign direct investment fdi 527 0.0220 0.0183 fixed asset investment fai 527 0.6996 0.2713 human capital human 527 8.6853 1.2224 research and development (r&d) investment rd 527 0.0145 0.0112 industrial structure upgrading inst 527 1.2119 0.6587 government intervention gov 527 0.2510 0.1893 global sustainability research global scientific research 45 (5) intensity of research and development (r&d) investment: r&d investment is the foundation of technological progress and is an important driving force for economic development. therefore, r&d investment has a certain degree of impact on regional developmental differentials. following the approach of liu renzhong et al. (2015), this study measures the intensity of r&d investment using the proportion of total r&d investment to gdp. (6) fixed asset investment: investment plays a crucial role in the economic effects on regions and influences regional economic disparities. following the approach of zhao lei et al. (2020), this study uses the proportion of fixed asset investment to gdp to measure the level of fixed asset investment. the six aforementioned factors interact through the cyclical mechanism of "efficiency improvement – resource agglomeration – path dependence": industrial structure upgrading and scientific research input determine longterm growth potential, government intervention and fdi influence the direction of resource allocation, while human capital and fixed asset investment directly affect production efficiency and capital accumulation. the uneven development across regions in these dimensions ultimately forms a multidimensional and superimposed economic disparity pattern.the descriptive statistical results for each variable are shown in table 2. data sources this study utilizes panel data from 31 provinces in china from 2004 to 2020 to explore the impact of tourism industry agglomeration on regional economic disparities. due to data availability, this research does not include data from hong kong, macau, and taiwan. the statistical data mainly come from various sources including the china tourism statistical yearbook, china statistical yearbook, compilation of statistical data on 60-year new china, china regional economic statistical yearbook, china economic information network statistical database, provincial statistical yearbooks, and national economic and social development statistical bulletin. in addition, this study employs linear interpolation to address individual missing values in the variables. dependence analysis in this paper, the pearson correlation coefficients between the variables are measured separately to verify whether there is multicollinearity between the explanatory variables. the results are shown in table 3. the absolute values of correlation coefficients between variables are basically not higher than 0.6, indicating that there is basically no multicollinearity between variables. in order to ensure the robustness of the research results, this paper applies the variance inflation factor method to test whether there is multicollinearity between the variables, the formula of which is shown in (6). when it is greater than 10 it means that there is basically multicollinearity between the variables. the last row of table 3 indicates that the vif of each explanatory variable takes the range of (1.70, 3.19), and its mean value is 2.41, which is much smaller than 10, which indicates that there is basically indeed no multicollinearity among the explanatory variables, suggesting that the results of the study are credible. vifi=(1-ri 2) -1 (6) global sustainability research global scientific research 46 table 3. dependence analysis for key variables variable gap ta fdi fai human rd inst gov gap 1.0000 ta

could appear highly correlated, leading to the issue of 'spurious regression. therefore, in the regression analysis, if the panel data are non-stationary time series, the research results will be meaningless. based on this, in order to avoid “pseudoregression” in the regression results, this paper, before the model regression, first conducts the unit root test of smoothness for the panel data. to ensure the robustness of the regression results. considering that the limitations of a single test method may cause some bias to the test results, this paper adopts five different unit root tests for each variable, namely, llc, ips, hadrilm, fisher-adf, and fisher-pp test, to improve the credibility of the test results. to determine stationarity, a majority rule is applied, where the results

the variables are non-stationary series. however, there are still some results that accept the original hypothesis. fisher's test is more reasonable than other tests when the variables are not infinite samples and the individual time series are allowed to have random factors. based on this criterion, the fisher-adf and fisher-pp tests show significant statistics for all variables, indicating stationarity. although the fisher test is more reasonable than the results of other tests under the above conditions. however, the test principle of smoothness has certain differences and complexity, and ignoring the results of other tests may cause judgment bias. therefore, this paper further takes more than half of the test results of the same variable rejecting the original hypothesis as the judgment criterion that the series of the variable is a smooth time series to ensure the robustness of the judgment results. the results show that all variables, more than half of the test results reject the original hypothesis, i.e., there is no unit root, indicating that all variables are smooth series. based on this, the next step of regression analysis can be carried out. benchmark regression based on the theoretical analysis and research hypotheses mentioned above, this study conducted an empirical analysis of the impact and moderating mechanisms of tourism industry agglomeration on regional economic disparities. the hausman test results indicated that the fixed-effects model was superior to the random-effects model. and the fixed effects model is better than the mixed ols model as obtained by the fixed effects model f-test. furthermore, considering factors such as the omission of individual effects, time effects, and the correlation between the error term and explanatory variables, which may bias the estimation results, the twoway fixed effects model was used as the benchmark regression model in this study. the results, as shown in table 5, present the benchmark regression model in column (1), whereas columns (2), (4), and (6) include additional variables such as information, transport infrastructure, and the interaction between information and transport infrastructure, respectively. columns (3), (5), and (7) introduce the interaction terms between tourism industry agglomeration and the moderating factors based on columns (2), (4), and (6), respectively. based on column (1), the coefficients of the impact of tourism industry agglomeration on regional economic disparities are significantly negative at the 1% level, indicating that tourism industry agglomeration has a significant mitigating effect on regional economic disparities. therefore, h1 was validated. this may be because the direct and indirect effects generated and facilitated by tourism industry agglomeration can promote economic development in underdeveloped areas, thus reducing the economic disparities between regions. additionally, an increase in tourism revenue can further drive the utilization and development of tourism resources, improve infrastructure, enhance enterprise management models, and promote the upgrading of the tourism industry chain, thereby generating further positive economic effects at the local level and further reducing the economic disparities between regions. lastly, the development of the tourism industry has significant advantages in expanding domestic demand, stimulating consumption, implementing macroeconomic policies, effectively driving sustainable economic growth, and mitigating economic disparities between regions. based on columns (2), (4), and (6), the coefficients of information, transport infrastructure, and their interaction show significantly negative impacts on regional economic disparities at the 1% level. this indicates that as these moderating factors continue to improve, the economic effects they generate and facilitate have a significant mitigating effect on the imbalance in economic development between regions. furthermore, the impact of tourism industry agglomeration on regional economic disparities remains significantly negative, indicating the robustness of the conclusions. global sustainability research global scientific research 48 based on column (3), the coefficient of the interaction term between tourism industry agglomeration and information infrastructure is significantly negative at the 1% level. this suggests that information infrastructure plays a negative moderating role in the impact of tourism industry agglomeration on regional economic disparities. this may be due to the higher information barriers in certain regions, leading to insufficient tourism demand and supply, which limits local tourism development to a certain extent. however, the improvement in informationization can increase the “exposure” of tourism resources, reduce the search cost for tourism table 5. regression results of fixed effects model of the full sample (1) (2) (3)

research global scientific research 49 information, stimulate innovation in tourism products, improve management models for enterprises, and promote the efficiency of factors such as labor and capital mobility and allocation. this allows for the rational utilization and development of idle or misallocated resources, reduces tourism leakage in the local area, and promotes the development of local tourism and related industries, thereby alleviating the imbalance in economic development between regions. based on column (5), transport infrastructure has a significant negative moderating effect on the impact of tourism industry agglomeration on regional economic disparities. this may be due to the lack of accessibility in transport, which leads to insufficient tourism demand and supply, thereby limiting the impact of tourism industry agglomeration on local tourism revenue. however, as transport convenience improves, it can increase the willingness of labor and tourists to work or travel to the local area, promote the flow and distribution effects of production factors such as labor and capital, and reduce transport costs for labor and tourists, as well as the transport costs of the tourism industry and raw materials. meeting dynamic and differentiated tourism demands can drive the utilization and development of tourism resources, improve infrastructure, enhance enterprise management models, and promote the upgrading of the tourism industry chain, thereby generating positive economic effects at the local level and narrowing the economic disparities between regions. based on column (7), the coefficient of the interaction term between tourism industry agglomeration and transport and information infrastructure is significantly negative at the 1% level. this indicates that considering the differences in transport and information infrastructure between regions and that is, the combined effect of transport and information infrastructure–there is still a negative moderating effect on the impact of tourism industry agglomeration on regional economic disparities. the interaction between tourism industry agglomeration and dual infrastructure types has suppressed the expansion of regional economic disparities, indicating enhanced spatial diffusion effects of economic factors. this phenomenon likely facilitates regional economic convergence through shared growth pathways . specifically, the negative feedback mechanism constrains the continuous intensification of agglomeration effects, compelling economic resources to shift toward new growth poles.traditionally, tourism agglomeration could exacerbate regional gaps through siphon effects , but the existence of negative multiplicative terms (as implied by the interaction between infrastructure variables) reveals that infrastructure modernization has fundamentally altered this mechanism. this transformation enables broader spatial distribution of tourism benefits, driving economic dividends to diffuse from agglomeration centers to peripheral areas.furthermore, this negative interaction reflects the emergence of diversified development trajectories. when tourism industries reduce their dependence on concentrated infrastructure investments in specific regions, regional economies gain enhanced risk resilience.these phenomena ultimately signify a paradigm shift in the coordinated development of tourism and infrastructure—from extensive growth reliant on factor concentration and scale expansion to high-quality and balanced development emphasizing network synergies, innovation-driven strategies, and systemic resilience. robustness tests (1) replacing the dependent variable: in study, the theil entropy index was employed to measure the degree of regional economic disparity. as shown in columns (1), (2), and (3) of table 6, the coefficients of the tourism industry agglomeration and the interaction terms with transport and information infrastructure, as well as the composite term of both, are significantly negative at the 1% level. this indicates that the moderating factors maintain a negative moderating effect on the impact of the tourism global sustainability research global scientific research 50 industry agglomeration on regional economic disparities, consistent with the baseline regression model, thus confirming the robustness of the results. table 6. robustness test results replacing the dependent variable replacing the independent variable (1) (2) (3) (4) (5) (6) ta 0.0816*** 0.0379*** 0.1133*** 0.0002 -0.0002

account for differences in regional economic scales, this study utilizes the location entropy index to gauge the level of tourism industry agglomeration, thereby eliminating the influence of the regional economic scale on the relative development level of the tourism industry. as shown in columns (4), (5), and (6) of table6, transport and information infrastructure, as well as their combined effect, continue to exhibit a negative moderating effect on the impact of tourism industry agglomeration on regional economic disparities, consistent with the baseline regression model, thus affirming the robustness of the findings. (3) excluding outliers: considering that outliers in regional economic disparity can lead to inaccurate regression results, this study adopts the method of liu et al. (2018) [28], employing a trimming approach based on the annual average values of regional economic disparity for robustness testing. calculations and sorting reveal that gansu has the highest annual average value of regional economic disparity, whereas fujian has the lowest. excluding these two provinces using the trimming method, the results presented in columns (7), (8), and (9) of table 4 indicate that transport and information infrastructure and their combined effect continue to show a negative moderating effect on the impact of tourism industry agglomeration on regional economic disparities. this consistency with the baseline regression model corroborates the robustness of our results. endogeneity test although a series of control variables is introduced in the baseline regression model, simultaneously controlling for individual and time effects to mitigate the estimation bias caused by omitted variables, there may still be a bidirectional causal relationship between tourism industry agglomeration and regional economic disparity, resulting in endogeneity issues. to address the bias in estimation results caused by endogeneity, this study initially uses the first-order lag of tourism industry agglomeration as the core explanatory variable. this approach effectively reduces the estimation bias caused by the contemporaneous correlation between the core explanatory variable and disturbance term. as shown in columns (1), (2), and (3) of table 7, the coefficients of the tourism industry agglomeration and the interaction terms with information and transport infrastructure, as well as the composite terms of both, are significantly negative at the 1% level. this indicates that even after overcoming endogeneity issues, the moderating factors still exhibit a negative moderating effect on the impact of tourism industry agglomeration on regional economic disparity. however, this method does not address the extent to which the endogenous variables of the current period affect the dependent variables of the current period, potentially causing bias in the moderating effect of information and transport infrastructure, as well as their combined influence. global sustainability research global scientific research 52 table 7. results of endogeneity test note: figures in parentheses represent z-values. *, **, and *** denote significance levels of 10%, 5%, and 1%, respectively table 7. continue. . . . ols 2sls (1) (2) (3) (4) (5) (6) l.ta/ta 0.0404*** 0.0195** 0.0552*** 0.0415*** 0.0231*** 0.0584*** (0.013) (0.009) (0.013) (0.013) (0.009) (0.014) dig -0.1133*** -0.1126*** (0.035) (0.033) l.ta/ta *dig -0.0860*** -0.0900*** (0.020) (0.021) tra -0.0462 -0.0344 (0.037) (0.035) l.ta/ta *tra -0.0896*** -0.0648*** (0.015) (0.015) fra -0.1576*** -0.1557*** (0.045) (0.042) l.ta/ta *fra -0.1089*** -0.1160*** (0.022) (0.022) _cons 0.4372*** 0.4550*** 0.4906*** 0.4026*** 0.4263*** 0.4486*** (0.056) (0.058) (0.057) (0.050) (0.051) (0.049) controlling variables controlling controlling controlling controlling controlling controlling time effect yes yes yes yes yes yes individual effect yes yes yes yes yes yes r2 0.4890 0.4790 0.5086 0.9001 0.8994 0.9042 n 527 527 527 527 527 527 liml (7) (8) (9) 0.0415*** 0.0231*** 0.0584*** (0.013) (0.009) (0.014) -0.1126*** (0.033) -0.0900*** (0.021) -0.0344 (0.035) -0.0648*** (0.015) -0.1557*** (0.042) -0.1160*** (0.022) 0.3743*** 0.3971*** 0.4324*** (0.063) (0.064) (0.063) controlling controlling controlling yes yes yes global sustainability research global scientific research 53 based on this, the study employs the lagged term of tourism industry agglomeration as an instrumental variable and uses the instrumental variables fixed-effects two-stage least squares (2sls) method for estimation. prior to the estimation, it was necessary to test the validity and effectiveness of the instrumental variable. the results of the tests were as follows: anderson canon. corr. lm statistic rejects the null hypothesis of “underidentification of the instrumental variable” at the 1% level. furthermore, the cragg-donald wald f statistic is significantly greater than the critical value of 16.38 at the 10% bias level, as determined by stock et al. (2002), significantly rejecting the null hypothesis of “weak identification of the instrumental variable.” therefore, the 2sls method was applied. the estimation results, as shown in columns (4), (5), and (6) of table 5, indicate that the coefficients of tourism industry agglomeration and its interaction terms with information and transport infrastructure are significantly negative, demonstrating that the moderating factors still influence the effect of tourism industry agglomeration on regional economic disparity even after addressing endogeneity issues. it is worth noting that, although the 2sls parameter estimation is consistent, there may still be bias in the regression results due to weak instrumental variables. consequently, this study employed the limited information maximum likelihood (liml) method for further estimation. the results, as presented in columns (7), (8), and (9) of table 6, show that the coefficients of the interaction terms between the tourism industry agglomeration and the moderating factors are significantly negative at the 1% level, further confirming the robustness of the results. heterogeneity analysis (1) regional heterogeneity analysis. this study divides the country into three major regions, east, central, and west, based on the classification standards released by the national bureau of statistics. a regional dummy variable, dum, was set, taking a value of one for the eastern region and zero for the central and western regions. these are incorporated into the model along with tourism industry agglomeration, information and transport infrastructure, and their interaction terms. the regression results are displayed in columns (1), (2), and (3) of table 8. the coefficients of the interaction terms between the tourism industry agglomeration and the moderating factors are significantly negative at the 1% level, indicating that the negative moderating effect of these factors on the impact of tourism industry agglomeration on regional economic disparity is substantially stronger in the eastern region than in the central and western regions. (2) temporal heterogeneity. the state council issued opinions on accelerating the development of the tourism industry (g.f. [2009] no. 41), which advocated for the vigorous development of the tourism industry and emphasized its importance in driving economic growth and enhancing public well-being. consequently, this study uses the date of issuance of this document as a sample split point, thereby dividing the entire investigation period into two intervals: 2004-2009 and 2010-2020, to explore whether the moderating effect of the tourism industry on regional economic disparity varies across these periods. based on this, a time dummy variable, dum, was set, with a value of 1 assigned to the years 2010-2020 and 0 to the years 2004-2009. these are incorporated into the model, along with the core explanatory variables, moderating variables, and their interaction terms. as shown in columns (4), (5), and (6), the coefficients of the interaction terms between tourism industry agglomeration and information and transport infrastructure are significantly negative, indicating that the issuance yes yes yes 0.9001 0.8994 0.9042 527 527 527 global sustainability research global scientific research 54 of the document strengthens the moderating effect of tourism industry agglomeration on regional economic disparity. (3) tourism industry development-based heterogeneity. given that the moderating effect of tourism industry agglomeration on regional economic disparity may vary with different levels of tourism industry agglomeration, this study adopts the methodology of liu et al. (2018) to calculate the annual average tourism industry agglomeration level for each province and city and then compares it to the national average. provinces and cities where the former exceeds the latter are termed tourism-dependent, whereas those where it falls short are termed non-tourism-dependent. on this basis, a dummy variable, dum, is introduced, with tourism-dependent provinces and cities assigned a value of 1, and non-tourism-dependent provinces and cities assigned a value of 0. these are incorporated into the model, along with the core explanatory variables, moderating variables, and their interaction terms. the regression results indicate that the coefficients of the interaction terms between tourism industry agglomeration and information and transport infrastructure are significantly negative at the 1% level, suggesting that, compared to non-tourism-dependent provinces and cities, tourism industry agglomeration exerts a more pronounced moderating effect on regional economic disparity in tourism-dependent areas. in other words, the moderating factors have a stronger regulatory effect on tourism industry agglomeration. table 8. results of

research 55 nonlinear discussion based on the theoretical analysis and research hypotheses presented earlier, this study examines whether there is a nonlinear relationship between the effect of tourism industry agglomeration on regional economic disparity and the role of transport and information infrastructure as well as their combined influence. to determine the number and thresholds of the information and transport infrastructure, as well as the combination of transport and information infrastructure, this study employs the bootstrap resampling method, drawing samples 500 times for model testing. the results, as shown in table 9, indicate that transport and information infrastructure individually pass the single-threshold effect test at the 10% and 1% significance levels, respectively, with threshold values of 0.6131 and 0.7266. furthermore, transport and information infrastructure pass the single and double-threshold effect tests at the 5% and 1% significance levels, respectively, with threshold values of 0.3040 and 0.6612. based on the results of the threshold effect tests, this study employs a single-threshold model to estimate the impact of information and transport infrastructure individually. a double-threshold model was used for the combined transport and information infrastructure. as shown in column (1) of table 10, when the level of information infrastructure is below the threshold, the coefficient indicating the effect of tourism industry agglomeration on regional economic disparity is -0.0151, significant at the 1% level. however, when the information infrastructure level exceeds the threshold, the coefficient becomes -0.0420, also significant at the 1% level. this finding demonstrates that, in regions with higher levels of information infrastructure, the absolute impact of tourism industry agglomeration on regional economic disparity is more pronounced than in regions with lower levels. this suggests that when information infrastructure surpasses the first threshold, it significantly enhances the interaction between tourism industry agglomeration and regional economic disparity. this outcome also indicates that the regulatory effect of information infrastructure on this relationship is nonlinear. thus, h21 is validated. table 9. test results of threshold effect threshold variable models threshold values f value

column (2), when the level of transport infrastructure is below the threshold, the coefficient indicating the effect of tourism industry agglomeration on regional economic disparity is -0.0158 and significant at the 1% level. however, when the level of transport infrastructure exceeded the threshold, the coefficient was -0.0346, which was also significant at the 1% level. this suggests that in regions with higher levels of transport infrastructure, the absolute value of the impact of tourism industry agglomeration on regional economic disparity global sustainability research global scientific research 56 is greater than that in regions with lower levels. this indicated a further mitigating effect between the two. this also implies that the regulatory effect of the transport infrastructure on this impact is nonlinear. therefore, h22 was validated. based on column (3), when transport and information infrastructure are within different threshold ranges, the coefficients of the impact of tourism industry agglomeration on regional economic disparity are all significant at the 1% level. specifically, when the level of transport and information infrastructure is below the first threshold, tourism industry agglomeration has a positive impact on regional economic disparity. when the level of transport and information infrastructure rises between the first and second thresholds, the impact transforms from positive to negative. when the level of transport and information infrastructure surpasses the second threshold, the mitigating effect of tourism industry agglomeration on regional economic disparity further increases. this indicates that the regulatory effect of transport and information infrastructure on this impact is nonlinear. hence, h2-3 is confirmed. table 10. estimated results of panel threshold model information infrastructure transport infrastructure combined transport and information infrastructure (1) (2) (3) ta(dig＜0.6131)

from 31 provinces in china spanning 2004 to 2020, this study empirically examines the relationship mechanisms between tourism industry agglomeration, transport, information infrastructure, and global sustainability research global scientific research 57 regional economic disparity. the conclusions derived are as follows: first, tourism industry agglomeration, transport, information infrastructure, and their combined effect all exert a significant negative impact on regional economic disparity. regarding the negative impact of tourism industry agglomeration on regional economic disparity, recent studies have provided mixed evidence. for instance, li and chen (2021) found that tourism agglomeration significantly reduces regional economic disparities in developed regions, aligning with our findings. however, wang et al. (2022) argued that the effect is context-dependent, with tourism agglomeration exacerbating disparities in underdeveloped regions due to uneven resource distribution. this contrast highlights the importance of regional heterogeneity, which our study further explores through heterogeneity analysis. second, information and transport infrastructure, as well as their combined effects, have a negative moderating effect on the impact of tourism industry agglomeration on regional economic disparity. this implies that moderating factors significantly alleviate the impact effect. the core research conclusions remain robust through endogeneity and robustness tests. the negative moderating effect of transport and information infrastructure on tourism agglomeration's impact is supported by zhang et al. (2020), who demonstrated that improved infrastructure enhances the spillover effects of tourism, thereby reducing economic disparities. however, liu and zhang (2023) noted that the moderating effect is weaker in regions with low levels of digitalization, suggesting that infrastructure quality matters. our study extends this by examining the combined effect of transport and information infrastructure, providing a more comprehensive understanding of their role. third, heterogeneity analysis reveals that in the eastern regions, from 2010 to 2020, and in provinces dependent on tourism, the moderating effect of tourism industry agglomeration on regional economic disparity is strengthened. finally, based on information and transport infrastructure and their combined effect, the tourism industry agglomeration exhibits a threshold effect on regional economic disparity. this indicates that the regulatory effect of the moderating factors on the impact is nonlinear. specifically, for information and transport infrastructure, the impact of tourism industry agglomeration on regional economic disparity is significantly negative and shows a decreasing trend. this signifies that surpassing the first threshold of transport and information infrastructure reinforces the mitigating effect of tourism industry agglomeration on regional economic disparity. for both information and transport infrastructure, the impact effect is positive at the first threshold, but at the second and third thresholds, the impact effect turns negative and exhibits a decreasing trend. as information and transport infrastructure improve, the impact of tourism industry agglomeration on regional economic disparity shifts. initially, it promotes disparity, but beyond a certain threshold, it helps mitigate economic differences.this reinforces the negative moderating role of transport and information infrastructure. the threshold effect of tourism agglomeration on regional economic disparity is consistent with the findings of gao et al. (2021), who identified a nonlinear relationship between tourism development and economic growth. similarly, chen and wang (2022) found that infrastructure improvements beyond a certain threshold significantly enhance tourism's positive impact on regional economies. however, our study uniquely incorporates both transport and information infrastructure as threshold variables, revealing a shift from promoting to mitigating disparities as infrastructure improves. as information and transport infrastructure improve, the impact of tourism industry agglomeration on regional economic disparity shifts. initially, it promotes disparity, but beyond a certain threshold, it helps mitigate economic differences. the following recommendations address this challenge. first, it is essential to scientifically understand the relationship between tourism industry agglomeration and regional economic disparity and formulate strategies tailored to local conditions to bridge the economic gap between regions. since transport and information infrastructure vary across regions, tourism development must be tailored to local conditions. otherwise, inefficient resource allocation may harm other industries. for instance, in regions with high information isolation and poor transport accessibility, tourism supply and demand may be insufficient. global sustainability research global scientific research 58 blindly developing tourism resources under these conditions may restrict tourism demand, thereby failing to boost local economic growth effectively. therefore, regions should combine theory with practical experience to scientifically assess their locational conditions before deciding whether to develop the tourism industry to promote economic benefits and reduce economic disparities in more developed areas. second, continuously improving the construction of information and transport infrastructure is crucial to enhance the efficiency of factor mobility. an integrated transport system should be constructed and perfected, including strengthening urban road construction, optimizing public transport routes, and increasing the density of public transport vehicles. this would promote the diffusion of the transport network within cities, reduce the mobility costs of tourists and labor, and lower the transport costs of tourism products and raw materials. consequently, this stimulates local tourism and related industries, thereby narrowing regional economic disparities. on the other hand, efforts should be intensified to advance information infrastructure construction and foster the integration of the tourism and information industries. innovations such as smart tourism, mobile payments, and big data applications can enhance the mobility efficiency of tourists, further promoting local tourism development, and subsequently reducing regional economic disparities. it is noteworthy that the development of transport and information infrastructure needs to be well-matched with tourism industry development. blindly enhancing the transport and information infrastructure alone will not necessarily enable the tourism industry to effectively promote economic benefits. finally, attention should be paid to the inter-regional linkages between the tourism industry and related sectors. governments should improve the construction of transport and information infrastructure between regions to reduce inter-regional mobility costs. this will strengthen cooperation between regions, allowing collaborative regions to fully utilize tourism resources and amplify the economic effects of complementary tourism resources and shared tourism markets. this, in turn, promotes the development of the tourism industry and related sectors, reduces regional economic disparities, and fosters coordinated regional development. declaration acknowledgment: n/a funding: zhejiang provincial philosophy and social sciences planning project: leisure experience perspective on the research of high-quality development countermeasures of lower tourism industry clusters and urbanrural synergy” conflict of interest: n/a ethics approval/declaration: n/a consent to participate: consent consent for publication: consent data availability: data will be made available on request authors contribution: guo junhui:primarily accountable for the development of economic models, formulation of corresponding assumptions, and involvement in the comprehensive revision process. chen qihao: i primarily global sustainability research global scientific research 59 assumed responsibility for data collection, empirical analysis of the constructed model, and manuscript preparation. references chen, l., & wang, j.

development, sustainable development, socio-cultural barriers, economic obstacles, environmental concerns, development. introduction the development of rural areas is a cornerstone for achieving sustainable national growth, particularly in countries like afghanistan, where a significant majority of the population resides in rural regions. approximately 71% of afghanistan's population lives in rural areas, predominantly engaged in agriculture, which forms the backbone of the country’s economy (yar & yasouri, 2024). however, these rural areas are often neglected, leading to a wide range of socio-economic challenges that hinder the overall development of the nation rahmani et al., 2021. rural development in afghanistan has historically been undermined by a series of complex and interrelated factors. decades of armed conflict, political instability, and weak governance structures have severely disrupted the social and economic fabric of rural communities. the lack of adequate infrastructure, including roads, schools, healthcar facilities, and energy access, further exacerbates these challenges, leaving rural populations isolated and deprived of basic services. additionally, afghanistan's rural economy is characterized by low agricultural productivity, global sustainability research global scientific research 82 which is largely due to outdated farming practices, insufficient access to modern agricultural technologies, and a lack of institutional support (zhu et al., 2022). the socio-cultural context of rural afghanistan also presents significant barriers to development. deep-rooted traditions and cultural norms often limit the participation of women and marginalized groups in economic activities, while migration from rural to urban areas contributes to the aging of the rural population and the erosion of traditional social structures. environmental issues, such as land degradation, water scarcity, and the impacts of climate change, further compound these challenges, threatening the livelihoods of rural communities and the sustainability of agricultural practices (das et al., 2023). despite the critical role that rural development plays in national stability and prosperity, efforts to address these challenges have been fragmented and inconsistent. previous strategies have often been top-down, with limited involvement of local communities in the planning and implementation processes. this approach has led to a lack of coordination among stakeholders, inefficient use of resources, and ultimately, the failure to achieve meaningful and lasting development outcomes (couper et al., 2023). in recent years, there has been a growing recognition of the need for a more holistic and integrated approach to rural development in afghanistan. this approach must address the multifaceted nature of the challenges faced by rural communities, combining investments in infrastructure, education, and healthcare with efforts to modernize agriculture and promote economic diversification. furthermore, it is essential to involve local communities in the decision-making process to ensure that development initiatives are tailored to their specific needs and contexts (dai et al., 2023). however, the current body of research on rural development in afghanistan is limited, particularly in terms of empirical studies that explore the practical implementation of development strategies. much of the existing literature focuses on theoretical frameworks without adequately addressing the on-the-ground realities faced by rural communities. this study seeks to bridge this gap by providing a comprehensive analysis of the institutional, socio-cultural, economic, environmental, and infrastructural barriers to rural development in afghanistan. this paper is structured as follows: section 2 provides a review of the existing literature on rural development challenges in afghanistan and comparable contexts. section 3 outlines the research methodology, detailing the document analysis and critical review methods employed in this study. section 4 presents the key findings, discussing the major obstacles to rural development in afghanistan and their implications for policy and practice. finally, section 5 concludes with a set of recommendations aimed at policymakers, development practitioners, and other stakeholders involved in rural development, emphasizing the need for coordinated and communitydriven approaches to overcome these challenges. this type of development is aimed at all economic, social, environmental, and political dimensions. thus, the question arises: what are the challenges, constraints, issues, and barriers to rural development in afghanistan? the innovation of this research lies in its comprehensive theoretical approach to identifying and critiquing the multifaceted challenges to rural development in afghanistan. by focusing on institutional, socio-cultural, economic, environmental, and physical infrastructure challenges, the study provides a holistic understanding of the barriers that hinder rural development in the country. the research methodology, which includes document analysis, critical review, and literature review, offers a robust framework for analyzing these challenges. the study's findings underscore the need for a coordinated and inclusive approach to rural development that involves effective planning, community participation, investment in infrastructure, and sustainable agricultural practices. this research contributes to the body of knowledge on rural development by highlighting the interconnectedness of the various challenges faced by rural communities in afghanistan and by suggesting strategic interventions for overcoming these obstacles. the study of rural development challenges in afghanistan, while comprehensive in its theoretical approach, reveals several gaps in the current research landscape. these gaps highlight the necessity for future research endeavors to delve into the practical manifestations of these challenges and to empirically validate the theoretical global sustainability research global scientific research 83 findings. specifically, there is a lack of empirical studies that directly engage with rural communities to understand the on-the-ground realities of development challenges. additionally, the study calls for in-depth case studies of specific villages or regions to capture the nuances of rural development in varied contexts within afghanistan. literature review rural development in afghanistan faces a multitude of challenges, exacerbated by decades of conflict, political instability, and a fragile economic base. as a predominantly agrarian society, with approximately 80% of the population residing in rural areas, the effective development of these regions is critical for national stability and prosperity. however, various structural, institutional, and environmental obstacles hinder progress, creating significant bottlenecks in rural development efforts. the rural sector in afghanistan faces numerous challenges, including climate change impacts, social and political instability, and economic disparities between urban and rural areas (faizi et al., 2024; haidary, 2023). drought, a consequence of climate change, significantly affects agriculture in the country and the farmers' livelihoods (faizi et al., 2024). to address these challenges, integrated rural development is required, which includes sectors like agriculture, health, education, infrastructure, and tourism (redclift, 2023). women's empowerment is a vital aspect of rural development and crucial for overall societal progress(hermawati et al., 2023). however, rural women face significant obstacles, including limited access to education, healthcare, financial resources, and decision-making processes. to overcome these challenges, gender-responsive rural development planning can establish an enabling environment for women's empowerment(faizi et al., 2024; hermawati et al., 2023) the objective of this research is to explore the vulnerability and coping capacity of farmers in arabmazari village to drought(faizi et al., 2024; hermawati et al., 2023). afghanistan faces challenges related to climate change, and social, political, and economic instability, which impact food and water security and agriculture (hermawati et al., 2023). rural development should focus on empowering women to foster personal growth and contribute to overall development (redclift, 2023). rural development objectives include increasing agricultural productivity, improving access to services like healthcare and education, and exploring economic sectors like rural tourism. the development of rural afghanistan is a complex challenge influenced by a range of socio-economic, institutional, and environmental factors. the key obstacles include weak agricultural support systems, inadequate infrastructure, water management issues, barriers to rural entrepreneurship, and ongoing security concerns. addressing these challenges requires a multi-faceted approach that integrates agricultural reform, infrastructure development, effective resource management, and enhanced governance. theoretical framework definitions of development: development, as a modern concept frequently mentioned in recent decades, has been defined by various scholars. the development signifies positive change. when referring to the development of a society or a social and economic system, it means the improvement of the general condition of each of its constituent elements. development pertains to the material quality of life as well as the processes of change and improvement that lead to increased living standards. it is not merely an economic phenomenon but encompasses a wide range of issues such as health, education, inequality, and poverty(rice et al., 2022). the contemporary concept of development, which has a more relative aspect, emerged in the 1960s. before that, concepts such as colonization, reform, improvement, modernization, and ultimately, growth were prevalent. however, with the rapid growth of industry and technology worldwide and the expansion of urbanization, the backwardness of rural global sustainability research global scientific research 84 areas became more apparent. since rural inhabitants earned less income than urban dwellers and had limited access to social, welfare, and educational services, the discussion of rural development arose to address severe poverty, improve living standards, create employment, and enhance productivity in rural areas(ya-feng et al., 2020). underdevelopment: underdevelopment does not mean a lack of development but rather refers to varying levels of development. underdevelopment is a means of comparing the level of development and also reflects the exploitation of one country by others(gonçalves, 2023). indicators of development poverty: poverty is a multidimensional phenomenon. it refers to the lack of essential public consumption needs, meaning there is an inadequate level of food, clothing, and shelter, as well as a lack of specific capacities, such as the ability to participate with dignity in society. unemployment: unemployment is the state in which a person of working age is unable to find a job despite actively seeking employment(yar & nasih, 2024). inequality: inequality manifests in various forms, including income inequality, unequal access to public amenities such as health and education, unequal voting rights, and disparities in power. national income: national income is the total value of goods and services produced within a country over a specified period (typically one year). rural development: in the early 1990s, rural development was synonymous with agricultural development. as rivera and qamar explain, rural development is a comprehensive and multidimensional topic that includes agricultural activities. according to madu izary, rural development involves helping rural inhabitants prioritize their needs by utilizing existing organizations. he also states that rural development enhances the socio-cultural environment of rural areas and strengthens individuals' abilities to achieve sustainable income and welfare(zhang et al., 2019). sustainable development strategies for rural areas particularly in the agriculture and food sectors, involve establishing guidelines for agriculture and food as a core component of economic growth recovery, under the conditions of ensuring national food security and guaranteeing the safety of food for rural populations. this strategy involves utilizing natural, material, and human resources in agriculture, with environmental sustainability ensuring the supply of high-quality agricultural and food products for domestic and foreign markets. the national strategy framework, agricultural programs, and projects focus on sustainable rural development as a key factor for economic growth, guaranteeing a strong rural economy. this is based on modern rural infrastructure, adequate technological support for rural areas, and the use of renewable local natural resources for economic, environmental, and landscape protection, thereby achieving an acceptable rural living standard and reducing severe poverty in rural areas(yang et al., 2022). sustainable economic development can be achieved primarily through mediumand long-term investments in strengthening agricultural resources, cultivation, processing units, advanced technologies, and adequate infrastructure in rural areas through constructed irrigation, land drainage, anti-erosion systems, forest shelterbelts for proper protection, flood control systems, and so on. given the significant global emphasis on agricultural activities, a series of actions is required to revive and make this sector profitable: developing models that are suitable for small-scale farming, considering the unique characteristics of agriculture, actions to increase the competitiveness and profitability of small indigenous farms, increasing levels of financial support, maintaining and encouraging entrepreneurship, attracting a larger share of traditional global sustainability research global scientific research 85 products to the market, providing a greater amount of free advisory services tailored to the real needs of small farms, simplifying the processes related to providing information (jat et al., 2019). methodology this study employs a theoretical approach, utilizing document analysis, critical reviews, and an extensive literature review. document analysis enabled a comprehensive examination of government reports, academic studies, and other relevant sources. a critical review provided insights into the key barriers hindering rural development, while the literature review synthesized findings from recent research to develop a robust theoretical framework. data analysis focused on identifying institutional, sociocultural, economic, and environmental challenges, and synthesizing these findings into actionable insights. although the study is based on secondary data, the analysis offers a comprehensive understanding of the obstacles to rural development in afghanistan. general information about the study area ten referred to as the "heart of asia." the capital of afghanistan is kabul. afghanistan shares borders with turkmenistan, uzbekistan, tajikistan, china, pakistan, and iran. according to the estimated statistics of 2020, afghanistan's total population is approximately 32.9 million, of which 16.8 million (51%) are men and 16.1 million (49%) are women. about 23.4 million people (71%) live in rural areas, 8 million (24.8%) in cities, and 1.5 million (4.6%) are nomadic (nsia, 2020). afghanistan has a highly diverse climate, which allows the production of various agricultural products. grain production, particularly wheat, is a fundamental crop, followed by vegetables and fruits. livestock farming is an integral part of agriculture and a primary activity for the rural community. however, livestock farming is also widespread among nomadic and semi-nomadic people. afghanistan is recognized as an agricultural country in the region and the world, and a significant portion of its exports consists of agricultural and livestock products. thus, agriculture holds a special place in the economic structure of this country (rahmani et al., 2021; yar et al., 2023). research findings it is an undeniable necessity that specific challenges and obstacles to rural development exist in every country. for example, the challenges in achieving sustainable rural development in india include population growth, natural resource degradation, environmental pollution, limited access to education, youth unemployment, poor health due to lack of healthcare, and weak infrastructure for receiving information. these challenges also include issues related to globalization and livelihood problems. the following will focus on the challenges of rural development in afghanistan. challenges to achieving rural development in afghanistan afghanistan faces numerous challenges and obstacles in rural areas on the path to sustainable development. to achieve rural development in afghanistan, attention must be paid to all economic, social, institutional, and environmental dimensions. it is important to note that focusing on one structure while neglecting others can lead to failure in the development process. therefore, to achieve sustainable development in general and rural development in particular, these challenges and obstacles must be analyzed. this will draw the attention of policymakers and planners to create suitable conditions for addressing these obstacles with effective solutions global sustainability research global scientific research 86 and programs. below are some of the most significant barriers and fundamental challenges to rural development in afghanistan (essar et al., 2023). poverty: afghanistan is currently facing numerous problems. millions of people live below the poverty line and suffer from severe hunger. low living standards and widespread poverty, especially in rural areas, are the primary challenges to the country's underdevelopment. the ongoing conflict for more than forty years has exacerbated these issues. in afghanistan, poverty inequality is more severe in rural areas than in urban areas, and it is especially high among nomads. nomads rely on livestock herding and constantly search for grazing land. a survey by the central statistics organization of afghanistan, conducted in 2016 and 2017, shows that more than 54% of afghans live below the poverty line. poverty levels are 18% in cities, 61% in rural areas, and 89% among nomads. the poverty rate in afghanistan is extremely high, with more than 60% of rural and nomadic populations living below the poverty line. half of the country's population earns less than one dollar a day, and the main source of income for rural inhabitants and small-scale farmers is subsistence production. according to statistics, most of the country's wealth is concentrated in the hands of less than 30% of the population, while over 70% of the people are poor or live below the poverty line. additionally, wealthy individuals often transfer or invest their capital outside the country, which poses a significant threat to the country's economic growth and development. people living in rural areas of afghanistan face challenges such as low agricultural productivity, limited technical knowledge and skills among farmers, inadequate service provision, and inefficient resource use, all of which contribute to increased poverty(yar & nasih, 2024). rural roads: afghanistan's rural roads face two major issues: mountainous terrain and damage from decades of war. of the roughly 40,000 villages across afghanistan, more than 40% have dirt roads, and only about 38% have access to proper roads. unemployment: in 2020, the labor force participation rate for men was 68.4%, while for women it was 16.5%, reflecting the lower employment rate among women compared to men. the unemployment rate among youth in rural areas was 29.6% in 2016 and dropped to 22.3% in 2020. unemployment is a significant and fundamental problem for rural residents in afghanistan, contributing to increased migration from rural to urban areas and further exacerbating urban problems(mahgoub et al., 2024). low productivity: today, agricultural development is key to improving welfare in many developing countries. approximately 71% of afghanistan's population lives and works in rural areas, and 61% of households derive income from agriculture. agriculture is a major component of rural development in afghanistan and can play a crucial role in reducing poverty and promoting sustainable growth through job creation, productivity improvement, and inclusivity. however, several challenges affect the low productivity of the agricultural sector, including management challenges, water scarcity, and traditional usage, lack of medicine, materials, and chemical fertilizers, land fragmentation due to inheritance laws, difficulties in preserving natural resources, particularly deforestation, lack of equipped laboratories for pest detection, limited support programs for production, and rural self-sufficiency, as well as land grabbing of government and private properties(rahman et al., 2017). according to the world bank's 2014 report, it was recommended that afghanistan's agricultural sector focus on three sub-sectors for economic sustainability: irrigated wheat, horticulture (including fruits, nuts, and vegetables), and livestock (including dairy, eggs, and poultry). these recommendations are based on their suitability for small-scale, intensively irrigated areas and peri-urban zones, which are expected to provide added value and employment. additionally, studies by the international labor organization indicate that grapes and tomatoes generate the highest per-unit income. the regional market for grapes is highly competitive, and the establishment of a cold chain is essential for realizing potential growth in this sector. wheat is the most widely cultivated crop, supporting the income of approximately 47% of households in afghanistan, but it provides the lowest income per unit among the five crops examined(eini-zinab et al., 2021). high population growth: afghanistan's population growth rate is high, and neither new technology adoption nor scientific research to enhance agricultural products and domestic global sustainability research global scientific research 87 production are evident. the continuous 2.4% population growth rate in the long term is a cause for serious concern, as most poor families have many children, which exacerbates economic inequalities. the average population growth rate in afghanistan during the mentioned period was 3.15%, and it has never experienced a rate below 2%. it is predicted that afghanistan's population growth rate, particularly in rural areas, will remain constant over the coming decades. the rapidly growing population increases pressure on the country's resources, service delivery, and labor market, which is already affected by a lack of sustainable jobs (bozorgzadeh & mousavi, 2023). education: in afghanistan, rural residents have limited access to basic amenities compared to urban dwellers. for instance, in education, due to security threats, a lack of educational facilities, and teachers, particularly female teachers, more than 42% (5 million) of eligible children do not have access to education. six thousand schools lack buildings and other essential facilities, and hundreds of schools are located far from residential areas (manalai et al., 2022). the literacy rate in afghanistan among men (aged 15 and above) is 62%, while among women it is 18%. in this country, only one in five women is literate, and the literacy rate for women in rural areas is three times lower than in urban areas. the ministry of education in afghanistan faces a shortage of professional teachers, with more than 40% of school teachers being non-professional, representing a major challenge for the country's education system. the current curriculum does not meet afghanistan's needs, and other significant challenges, especially in rural areas, include a lack of textbooks, desks, chairs, and school buildings. not all regions are capable of providing equal education (manalai et al., 2022). challenges in management, regulation, and planning (policy-making) one of the significant challenges in rural development in afghanistan is the lack of effective planning and management. historically, the country has adopted a top-down approach with centralized decision-making, excluding local communities from the development process. this has resulted in poor coordination, increased costs, and inefficient use of resources, ultimately creating dissatisfaction among rural populations. moreover, this mind map illustrates the major categories and their specific challenges, providing a clear overview of the issues facing rural development in afghanistan. global sustainability research global scientific research 88 rural development has been politicized, and accountability in policy implementation remains weak. the absence of a coherent strategy for sustainable rural development, coupled with a lack of coordination between governmental and non-governmental organizations, further exacerbates the situation. theoretical weaknesses and the absence of practical models have hindered progress. moreover, the involvement of communities in planning and execution has been minimal, and non-governmental organizations have struggled to play an effective role due to lack of collaboration and communication with governmental institutions. sustainable development efforts require decentralization, more active community participation, and better alignment between local needs and national policies(story & carpiano, 2017). social challenges the social landscape in rural afghanistan presents numerous challenges for development. one of the most pressing issues is the migration of the younger population from rural to urban areas, leading to the aging of rural communities and a loss of workforce. cultural and traditional barriers, including gender inequality, hinder the participation of women and marginalized groups in economic and social activities. educational attainment remains low, and access to basic services such as healthcare, education, and sanitation is limited, particularly in remote areas. there is also a lack of awareness among rural populations about sustainable development practices and their rights. social cohesion is weak, and community participation in development initiatives is minimal. addressing these social challenges requires targeted efforts to empower local communities, promote gender equality, and improve access to education and essential services(yar & yasouri, 2024; rijal et al., 2020). economic challenges rural development in afghanistan faces numerous economic barriers. a key challenge is the ineffective cooperation and weak economic infrastructure in rural areas. most rural communities lack access to essential markets, which hampers their ability to commercialize agricultural products. the economic structure remains heavily reliant on subsistence farming, with limited diversification into non-agricultural sectors such as tourism or rural industry. furthermore, the agricultural sector suffers from low productivity due to a lack of modern technologies, inefficient farming methods, and insufficient support programs. limited access to credit and financial services further restricts economic growth. poverty remains pervasive in rural areas, with many families living below the poverty line. in addition, rural unemployment, particularly among youth, exacerbates migration to urban areas, contributing to further economic imbalance between rural and urban regions. economic diversification, improved market access, and increased investment in rural industries are critical to overcoming these challenges(zhang et al., 2022). environmental (ecological) challenges environmental protection is the most crucial element of sustainable development. environmental damage not only reduces the productivity of agricultural and non-agricultural activities but also poses health risks for humans, animals, and other forms of life. to ensure that economic and social progress is sustainable and institutionalized, preventing environmental degradation is paramount. some of the environmental challenges facing rural development in afghanistan include: ➢ conversion of agricultural land to non-agricultural uses, ➢ unfavorable ecological conditions for sustainable rural development, global sustainability research global scientific research 89 ➢ weak management of natural disasters in rural areas, leading to reduced production due to floods, droughts, and cold weather, ➢ the imbalance between population and natural resources, ➢ over-exploitation of groundwater resources, ➢ use of inappropriate technology in agriculture and soil erosion, ➢ sanitation and wastewater pollution issues in villages, ➢ overuse of fertilizers, ➢ overgrazing of pastures, ➢ the emergence of animal epidemics(essar et al., 2022). ➢ physical (infrastructure) challenges the physical infrastructure challenges hindering rural development in afghanistan can be summarized as follows ➢ weakness (proper infrastructure in rural areas) unavailability of roads, banks, schools, etc ➢ structural defects in operational systems in most rural areas such as small farmers ➢ limited access to appropriate technology in rural areas ➢ limitation of access to modern knowledge and theology in rural areas ➢ unequal distribution of income, prosperity, and national facilities and opportunities between industry and agriculture. ➢ absence of a formal education system ➢ lack of connection between city and village to provide socio-economic services ➢ vulnerability of sometimes rural settlements to natural disasters ➢ lack of arrangement of space suitable for sometimes rural residence ➢ imbalance and growing inequality between urban centers and rural communities ➢ weakness in the transportation system(bagambilana & rugumamu, 2023) ➢ institutional and structural challenges institutional and structural challenges affecting rural development include: ➢ the dominance of sectoral thinking (despite the emphasis on comprehensive and spatial programs) over the overall planning process, ➢ lack of cohesive and effective communication between executive organizations in achieving program objectives, ➢ the existence of a centralized (top-down) management structure despite the acceptance of regional and provincial program decentralization, ➢ the presence of a centralized spatial structure in the country's spatial planning system, prioritizing urban centers over rural settlements, ➢ lack of belief in rural development among some decision-makers within the country’s planning structure, ➢ absence of a comprehensive rural development plan, ➢ lack of coordination between organizations responsible for rural development and the overlap of their duties, ➢ mismanagement of land and land use, ➢ absence of long-term and practical plans for the systematic organization of rural centers and spaces, ➢ lack of a clear legal framework for rural planning, global sustainability research global scientific research 90 ➢ absence of a specific model or framework for rural development, ➢ deficiencies in planning at various levels, such as the absence of local-level planning and lack of clear delineation of planning responsibilities at national, regional, and local levels (chen et al., 2022). planning that focuses on identifying central villages for providing necessary services, creating non-agricultural jobs, developing rural industries, consolidating agricultural lands, reducing rural migration, and developing human resources can address some of the existing challenges in rural development. discussion the examination of rural development challenges in afghanistan through a theoretical lens has yielded a comprehensive understanding of the intricate web of issues that hinder progress in the nation's rural areas. the study's findings underscore the interconnectedness of institutional, socio-cultural, economic, environmental, and physical infrastructure challenges, necessitating a multifaceted approach to rural development. the discussion of institutional challenges highlights the critical role of effective planning and management in rural development. the top-down approach and centralized planning that have characterized rural development efforts in afghanistan have often excluded local participation and failed to address the diverse needs of rural communities. this has led to inefficiencies and a lack of coordination, resulting in dissatisfaction among the rural population(zhang et al., 2022). socio-cultural challenges, such as migration and cultural barriers, have contributed to the aging of rural populations and the erosion of traditional rural lifestyles. the study suggests that addressing these challenges requires an understanding of local contexts and the empowerment of rural communities to engage in development processes. economic challenges, including low agricultural productivity and limited market access, are symptomatic of a broader lack of economic diversification and private sector involvement(yar & yasouri, 2024). the study indicates that stimulating rural entrepreneurship and improving market linkages are essential for enhancing rural economies. environmental concerns, such as land degradation and water scarcity, are not only threats to agricultural productivity but also to the health and well-being of rural populations. the discussion emphasizes the need for sustainable management of natural resources to ensure the long-term viability of rural communities. physical infrastructure challenges, including inadequate roads and technology access, underscore the necessity of investment in rural infrastructure to support economic and social development. the study argues that improved connectivity and access to technology are prerequisites for rural development. in conclusion, the discussion points to the need for a holistic and integrated approach to rural development in afghanistan that addresses the identified challenges in a coordinated manner. this approach must be inclusive, community-driven, and cognizant of the local context to ensure that rural development initiatives are effective and sustainable. conclusion rural development in afghanistan is hindered by a complex set of institutional, economic, social, and environmental challenges. these obstacles are deeply interconnected, and addressing them requires a holistic approach that emphasizes community participation, sustainable practices, and effective governance. key recommendations include decentralizing decision-making processes, improving infrastructure, and fostering economic diversification through modern agricultural techniques and rural industries. social challenges such as migration, gender inequality, and low educational attainment must also be addressed through targeted programs that empower rural populations and enhance their capacity for self-sufficiency. collaborative efforts among government entities, international organizations, and local communities are essential to drive meaningful and global sustainability research global scientific research 91 sustainable development in afghanistan’s rural areas. only by addressing these multifaceted challenges can afghanistan achieve long-term growth and stability in its rural regions. suggestions for rural development in afghanistan based on the comprehensive analysis of the challenges and barriers to rural development in afghanistan, the following strategies are suggested to facilitate the development of the nation's villages: 1. effective planning and management: implement decentralized planning and management systems that involve local communities and stakeholders in decision-making processes. this will ensure that development initiatives are aligned with the actual needs and aspirations of rural populations. 2. infrastructure development: invest in rural infrastructure, including roads, schools, healthcare facilities, and energy access. improved infrastructure will enhance connectivity, stimulate economic activities, and improve the delivery of essential services. 3. agricultural enhancement: introduce modern agricultural technologies, provide training and education to farmers, and improve irrigation systems to enhance agricultural productivity. diversify agricultural production to reduce dependency on a few crops and to increase resilience to market fluctuations. 4. economic diversification: encourage the establishment of rural industries, such as agro-processing, handicrafts, and tourism, to create employment opportunities and reduce reliance on agriculture. promote rural entrepreneurship and support smallscale businesses. 5. education and capacity building: expand educational facilities and improve the quality of education in rural areas. implement vocational training programs to equip the rural workforce with the necessary skills for modern economic activities. 6. healthcare services: improve access to healthcare by establishing rural clinics and health centers. train local health workers to provide basic healthcare services and raise awareness about health and sanitation. 7. environmental sustainability: implement sustainable land management practices, protect natural resources, and promote the use of renewable energy. address issues such as deforestation, soil erosion, and water pollution to ensure the ecological balance necessary for rural livelihoods. 8. community empowerment: foster a sense of ownership and participation among rural communities in development projects. support local institutions and organizations that can play a role in the implementation and monitoring of development activities. 9. gender inclusion: ensure the active participation of women in rural development processes. provide opportunities for education and employment that empower women and contribute to the overall development of rural areas. 10. international cooperation: leverage international aid and cooperation for technical, educational, research, and financial support. engage with global institutions to access resources and knowledge that can benefit rural development in afghanistan. by adopting these strategies, afghanistan can address the multifaceted challenges facing its rural areas and pave the way for sustainable development that improves the livelihoods of its rural population and contributes to national stability and prosperity. future researches to advance the understanding and practice of rural development in afghanistan, future research should focus on several key areas. impact evaluation studies are needed to assess the effectiveness of existing rural development policies and programs. this will provide valuable insights into the successes and failures of these initiatives, guiding future interventions. moreover, there is a need for research that adopts participatory approaches, involving local communities in the research process to ensure that the findings are relevant and actionable. interdisciplinary research that spans various fields such as economics, sociology, environmental science, and agriculture is essential to develop holistic solutions to rural development challenges. longitudinal studies will be crucial for tracking the progress of rural development over time and evaluating the long-term impacts of various global sustainability research global scientific research 92 strategies. technological innovations offer new avenues for addressing rural development challenges and research into the application of digital tools and renewable energy solutions could be transformative. gender perspectives are often overlooked in rural development research, and future studies should incorporate gender analysis to understand the differential impacts on men and women. a critical examination of current policies in light of the sustainable development goals (sdgs) is necessary to identify policy gaps and to advocate for policy reforms that align with international development goals. finally, comparative studies that benchmark afghanistan's rural development challenges against those of other developing nations could illuminate shared issues and successful strategies that could be adapted to the afghan context. declaration acknowledgment: we would like to express our gratitude to all individuals and

(1999), and mileti (1999) have emphasized the importance of building disaster-resilient communities. research views disaster resilience as a key goal in disaster management and planning (burby et al., 2000). efforts to measure disaster resilience typically focus on identifying characteristics or attributes of resilient individuals, communities, or systems. these measurements often incorporate multiple dimensions, such as physical, economic, social, and institutional factors. however, as noted by winderl (2014), no general measurement framework for disaster resilience has been empirically verified. among the frameworks reviewed are the climate disaster resilience index (cdri) (shaw and team, 2009), texas community disaster resilience index (tx-cdri1) (peacock et al., 2010), and coastal community resilience (ccr1) (courtney et al., 2008). while these frameworks provide valuable insights, each has limitations in design and implementation. the cdri, introduced by the international environment and disaster management laboratory of kyoto university, measures resilience across five dimensions: physical, social, economic, institutional, and natural. financial resilience is also linked to the ability to raise emergency funds and maintain savings to manage financial shocks (lusardi et al., 2011; salignac et al., 2019). research by tavares and hall (2016) and aiyar et al. (2019) has highlighted the importance of financial buffers, such as savings, in mitigating the impact of financial shocks on long-term well-being. scholars like lusardi and tufano (2015) and hanna et al. (2014) emphasize savings' role in protecting long-term assets, while sherraden (2018) suggest policy interventions to promote household financial resilience. further research is needed to explore resilience dynamics comprehensively and develop effective strategies for promoting financial resilience at the household level. this study aims to develop a conceptual framework for identifying indicators of disaster resilience, particularly economical resilience, within coastal communities, and to create a grading system for comparing and monitoring community resilience. while the study primarily focuses on the most climate-vulnerable and lowincome groups in a specific regional context, the tool itself has broader applicability. socio-economic structures and vulnerabilities vary significantly across countries and communities; therefore, contextual adaptation of the indicators is essential for meaningful use in other settings. the grading tool is based on mean values, which may not accurately reflect the resilience status of a heterogeneous population. applying it to a highly diverse or mixed sample without contextual adjustments could lead to misleading conclusions. however, when used within relatively homogenous vulnerable communities and adapted to local conditions, the tool remains a robust and transferable framework for assessing resilience. review of literature the framework for assessing community resilience and disaster preparedness was developed through a comprehensive literature review and extensive stakeholder and expert consultation. this approach ensured a consensus on key indicators, which were then weighted to evaluate resilience effectively. the framework integrates both quantitative and qualitative methods, incorporating public opinions and expert evaluations. economic capital is a primary focus in resilience assessment, with indicators such as household income, savings, access to insurance, credit, employment rates, and social safety nets. according to buckle (2001), these indicators are crucial in understanding how households navigate financial shocks. resilience, defined as the ability to withstand and recover from adversity, provides the theoretical basis for this framework. scholars like bonanno (2004) and norris et al. (2008) have highlighted the significance of individual and collective resilience in various domains, including finance. global sustainability research global scientific research 132 table 1. list of selected indicators indicators/ variables/source of resilience indicator explanation household financial savings that protect long term assets this is a financial (liquid asset – i.e., money or money equivalent) resource. the more liquid, the better. in between there would be some reserve but not enough to cover expected losses; some reserve but it is not reliable and/or the household often taps into it for non-disaster expenses. when this is aggregated, it should be weighted by percentage of houses with and without adequate financial buffers. consider the interaction between savings, insurance or credit (households may use one as their buffer and may not need all three). communal social safety net this source looks at financial protections at the local level. this is again financial protection specifically set aside or contingent on disaster. include provision from local government, local religious organizations, community emergency funds etc. household credit access this source looks at the availability of credit for members of the community. key aspects of the assessment are: it can be formal or semi-formal; community access to financial services does not diminish during and after a disaster and even improves (greater access to financial services) risk transfer mechanism/insurance community access to financial services so that it could be transferred the risk to come back better. household income continuity strategy this source looks at the economic activity within the community and the ways in which income is derived and maintained during disasters. it considers any livelihood strategy that allows a household to maintain or quickly restore a flow of income (e.g., ability to work remotely, have access to business lines of credit, have alternate livelihoods that can be switched to, have remittance from family members outside the disaster area, etc.). the relationship between communal social safety nets and resilience is well-documented. scholars such as putnam (2000) and berkes and ross (2013) emphasize that strong social ties, effective local governance, and active community engagement contribute significantly to informal and formal support systems, enabling communities to better navigate crises. cultural and traditional practices also play a significant role in resilience, as explored by adger (2003) and manyena (2006). these practices can foster a sense of identity, solidarity, and adaptive capacity, contributing to the development of communal safety nets. household income continuity strategies are another key aspect of resilience. strategies for maintaining household income during shocks are key to financial resilience. studies by stephens and szafarz (2012), duflo and udry (2004), and barrett et al. (2001) highlight how income diversification helps mitigate financial disruptions. in parallel, dercon and krishnan (2000) and fafchamps (2003) emphasize the role of informal networks in preserving income continuity. savings and financial planning are crucial for resilience, with lusardi and mitchell (2011) emphasizing the need for well-structured financial plans to buffer against income volatility. government global sustainability research global scientific research 133 assistance programs, including unemployment benefits and cash transfers, are vital in supporting households during periods of income instability, as discussed by bitler and hoynes (2016). as armendariz de aghion and morduch (2005) explain, “access to credit helps poor households manage cash flow, invest in small enterprises, and build resilience against economic shocks.” insurance mechanisms are vital for resilience, particularly in risk transfer and recovery. dercon and hill (2009) assert that “insurance is not merely a financial instrument, but a mechanism that allows households to take productive risks and protect long-term welfare.” browne and hoyt (2000) state, “catastrophic insurance provides crucial financial support that enables households and businesses to recover from severe natural disasters and economic shocks.” in summary, the framework emphasizes the importance of household savings that protect long term assets, communal social safety nets, income continuity strategies, credit access, and insurance in building resilience (table 1). however, further research is needed to address challenges related to credit and insurance access, affordability, and the long-term effects of these strategies on resilience. the integration of these indicators into the framework provides a comprehensive approach to understanding and enhancing resilience at both household and community levels. materials and method area of study the study area was selected purposefully. at first the researcher wanted to access in the most vulnerable community and cooperation of ngos who are working in these areas. it was found that islamic relief bangladesh has good presence in the selected most vulnerable communities and working to enhance resilience of a large number of hh that were needed of the researcher as selection of population and sample size for study. islamic relief bangladesh accepted the request of the researchers and agreed to collaborate. figure 1. study area global sustainability research global scientific research 134 to select the study area, national secondary data was reviewed and identified shyamnagar subdistrict under satkhira district is in 5th position, koyra of khulna is in 9th position and jashore was in 40th position in terms of multi hazard. though jashore was in 40th position but water logging is serious issue for this area (draft report, cvi , undp,2023). the unions and wards were selected through consultation with the different level key informants. each key informant was given a score sheet to put score using three-point likert scale considering the vulnerable situation like poverty status, food security, job opportunity, transport

enhancing climate resilience project in the monriampur, shyamnagar and koyra subdistrict under the district jashore, satkhira, and khulna subsequently. method in measuring community resilience concerning financial capital, we adopted the climate disaster resilience index (cdri), a planning tool developed by the climate and disaster resilience initiative of kyoto university (shaw et al. 2010). additionally, we considered the 5 capitals model, inspired by dfid's sustainable livelihoods framework (slf) (dfid, 1999; keating et al., 2014), which identifies five complementary forms of capital sustaining communities: human, social, physical also fitting with this thinking is practical action’s vulnerability to resilience (v2r) framework natural, and financial (pasteur, 2011). each capital is made up of a number of “sources”. under the financial capital there are 5 sources. resilience sources are classified according to the 5 capitals, each symbolizing a unique element that enhances overall resilience. it also followed the zurich flood resilience measuring tools (frmt) (karen,et al 2019). the selection of variables was global sustainability research global scientific research 136 adapted to the local context, gathering corresponding indicators and, when needed, finding appropriate alternatives. the framework's development began with compiling an initial set of indicators and variables, informed by a thorough literature review. stakeholder and expert input were also crucial, as their perspectives were used to reach a consensus on the key indicators. additionally, weights were assigned to these indicators to evaluate community resilience and disaster response capability. this framework integrates both quantitative methods and qualitative approaches, including public opinions and expert judgments. weighting we used grade point index (gpi) method to compute the scores for each parameter and dimension, respectively. data were computed in excel to calculate scores and describe them in different charts diagrams. all sources are given equal weight of each capital. financial capital has five sources of resilience named (x1, x2 , . . x5 ). each source is graded a, b,c,d were given weight 4,3,2,1 respectively. where the categories denote a: best practice for managing the risk b: good industry standard, no immediate need for improvement c: deficiencies, room for visible improvement d: significantly below good standard, potential for imminent loss source grade point index was calculated for each source of resilience using following formula grade point index (gpi) = (grade weight× number of respondent) (grade weight× total respondent ) example, x1a = (4× n1) (4× n ) where, x1= source of resilience a= grade or resilience n1= number of respondents against grade a of resilience source 1 n= total number of respondents sample distribution for qualitative survey the breakdown of fgds and kiis conducted within the qualitative

examines whether the instrument of building resilience of a community works together that reflect the capacity of community to institutions. obtaining reliable quantitative data on activities of both government and ngos is a chronic issue in bangladesh; our research therefore applied mixed method qualitative, quantitative, tools and techniques. both primary and secondary data sources were used for empirical investigation and policy analysis. to collect the primary data from local communities, we applied participatory rural appraisal tools, such as wealth being analysis, focus group discussions (fgds), household interviews and key informant interviews. we analyzed data procured from a total of 318 households distributed across the unions, which were systematically selected to conduct the interviews and fgds. we received 100% response from the targeted households for household interview. it was considered different sex, age for interview. six fgds were carried out by administering a semi-structured questionnaire to the village. for policy analysis, we relied chiefly on secondary data, which were supplemented by primary data. official documents from the government, study reports from ngos and other organizations, journal articles, newspaper clippings and internet resources from reliable and responsible sources provided additional information for our analysis. it was collected information from different key informant structured score sheet was used as well as informal discussions were done. following a comprehensive plan, the enumerators completed the field works within the stipulated timeline using pre-designed checklists and questionnaires. well trained enumerators collected the household level data using kobo toolbox data management platform. researchers oversaw spot checks on a subset of respondents to maintain accuracy and consistency. after collection, open-ended responses were coded and entered suitable software like ms-excel, then cleaned by the data analyst, with thorough checks on at least 10% of the data. for qualitative data, researcher conducted fgds, kiis. emphasis was placed on meticulous documentation and analysis, adhering to professional standards. qualitative data was analyzed through thematic analysis to identify the pre-defined themes from the transcribed data. through the analysis, the similar issues were identified and then they were put together theme-wise. results and discussion demographic information the demographic information of the surveyed households reveals that 91% of participants were women, while nearly 9% were men. the age distribution indicates that 47% of respondents fall within the 31-50 age group, 26% are aged 16-30, and 7% are 60 years or older. in terms of housing conditions, 78% of the respondents live global sustainability research global scientific research 138 in katcha houses, with 10% residing in semi-pucca houses. regarding education, 65% of respondents have completed 1-5 grades, 28% have completed 6-10 grades, 3% have obtained their secondary school certificate (ssc), 2% have reached the higher secondary certificate (hsc) level, and 3% have attained a graduation degree. the literacy rate for those aged 7 years and above is 74% at the national level. occupation-wise, 48% of respondents are daily laborers, 18% engage in fishing, 12% in livestock or poultry rearing, 7% in rickshaw or van driving, 4% in crop production, and 1% in auto rickshaw driving, with various other occupations also represented (table 4) table 4: demographic information of study area indicators features

(pra), a climatic hazard trend analysis was conducted for each subdistrict. the findings indicate that over the past 10 to 20 years, there has been a noticeable increase in the frequency and intensity of various climatic hazards in coastal areas: the occurrence of cyclones and tidal surges has escalated from medium to very high. the frequency of heavy rain/flood/waterlogging has increased from medium to high. drought/extreme heat conditions have intensified, rising from low to high. the frequency and impact of storms have increased from low to high. the severity of salinity issues has significantly increased, moving from low to very high. these trends highlight the growing vulnerability of coastal areas to climatic hazards. household financial savings that protect long term assets when it was asked about the income and expenditure 67% of total respondent said their income is 500110000tk per month where as 70% respondent mentioned their monthly expenditure is around 5001-10,000tk. it means that 3% respondent who has monthly income around 5001-10000tk are in debt and they need to get loan or borrow. it reveals that 70% respondent in this category has no scope to save from their monthly income. similarly, the income group of >5000tk are 24% and 21% respondent do expenditure this range of amount. it seems that 3% of the low-income group has some scope to save something (table 6). when respondents were asked about the head of their family expenditure it was found that almost 100% people expense for food purchasing and that was average 4500bdt in all area. among the three subdistricts shyamnagar was found high then monirampur and then koyra spent food purchasing. less expense was found in productive asset purchase.

(2004) in their pressure and release (par) model, which explains disasters as the outcome of hazards intersecting with conditions of vulnerability. the persistent use of fragile building materials, low awareness, and poor infrastructure in the studied regions reinforces the notion that underlying socio-economic drivers continue to exacerbate climate risks. economic insecurity emerges as a key dimension of vulnerability in all three locations. the lack of income diversification and the reliance on climate-sensitive livelihoods—such as fishing, daily labor, and leaf collection—mirror the concerns raised by ellis (2000), who stressed the importance of diverse livelihood portfolios for enhancing resilience. furthermore, the study's evidence of poor nutrition, inadequate savings, and erosion of home structures due to soil salinity reflect what davies (1993) describes as "erosive coping strategies"—short-term survival tactics that undermine long-term well-being. these issues perpetuate the poverty-vulnerability trap, as discussed by chambers (1989), and severely limit adaptive capacity during and after disasters. water scarcity, inadequate sanitation, and deteriorating health conditions further compound the resilience deficit. these findings are in line with the ipcc (2014), which emphasizes that climate change has direct implications for public health and development. in particular, the persistent issue of salinity intrusion in koyra and shyamnagar echoes the work of rabbani et al. (2013), who found that saline water not only affects 0 20 40 60 80 100 120 enabling environment community level context resilience a b c d global sustainability research global scientific research 147 agriculture and housing but also significantly threatens drinking water availability and health outcomes, especially among the poorest households. despite an increased allocation in the national social protection budget, access to social safety nets remains limited. although programs like the vgd, vgf, oaa, and ffw are in place, the study shows that only 41% of vulnerable citizens benefit from them—far below the target of 3% of gdp set by the national social security strategy (nsss). this aligns with barrientos (2010) and sabates-wheeler & devereux (2008), who argue that systemic issues in targeting, implementation, and resource distribution often render social protection programs ineffective in reaching those most in need. the high number of residents in the "yellow" category of the resilience matrix indicates that while some support exists, accessibility and coverage remain inadequate. financial exclusion is another major barrier to resilience. the absence of insurance coverage among surveyed populations highlights a critical gap in risk transfer mechanisms. this supports the findings of kunreuther and pauly (2006) and crichton (2006), who argue that insurance is vital for financial stability in disaster-prone areas. however, in low-income communities, uptake remains low due to affordability, lack of trust, and the reluctance of providers to enter high-risk markets. likewise, microfinance institutions in cyclone-prone areas show hesitancy in lending to vulnerable groups, reinforcing insights by dercon and christiaensen (2011), who note that financial risk-sharing tools often fail to reach the poorest, thereby hindering recovery and reinforcing vulnerability cycles. the study reaffirms insights from the broader literature that building resilience requires a systemic approach that goes beyond hazard response. it calls for investments in livelihood diversification, climate-smart social safety nets, access to microinsurance, and inclusive financial services. these interventions must be coupled with stronger governance and policy alignment to bridge the gap between national strategies and local implementation. by highlighting these interlinked challenges and gaps, the study contributes meaningfully to ongoing global dialogues on resilience, risk reduction, and climate justice. conclusion and recommendations in conclusion, achieving resilience in these vulnerable communities is crucial, as it directly impacts their wellbeing and development. the study underscores the severe limitations in financial capacity, the absence of alternative income options, and the lack of household financial savings for safeguarding long-term assets. while the government has implemented several social safety net programs, their allocation remains disproportionately low compared to the high demand. nearly 90% of indicators fall into the red category, with only 10% in the yellow category, indicating significant challenges in accessing insurance, inadequacies in adaptation financing, and a pressing need for policy initiatives to develop off-farm iga skills, reduce dependency on natural resources, expand insurance coverage, and improve access to climate funds such as loss and damage, adaptation, and resilience funds. key informant interviews and national policy reviews reveal a disconnect between the government's robust disaster management and adaptation policies and the bottlenecks in local financing mechanisms, depriving the most vulnerable communities of essential government allocations. additionally, the bangladeshi government faces limitations in its capacity to meet the growing demands. therefore, there is a pressing need for global attention and support to ensure that these vulnerable communities in bangladesh receive the necessary assistance for building resilience and achieving sustainable development. finally, it could be said that the formulated resilient grading tools under this study for community disaster resilience is enable for quick assessment of a vulnerable community to understand the gap and essential need to make the community resilient. it also able to compare different communities in terms of resilient and encompass the decision makers in prioritization interventions. this resilient grading system is capable to global sustainability research global scientific research 148 continuous monitoring of resilience levels of a community that contributes in operational planning, management, decision-making, and policy formulation. the policy makers, development agencies and private sector could consider this resilience grading method in prioritizing vulnerable area, planning interventions, management, decision-making, policy formulation and monitoring. further research is needed to validate and standardize the resilience grading system across diverse ecological zones, ensuring its applicability and reliability in varied contexts. utilizing longitudinal data will be crucial to evaluate the tool’s effectiveness in tracking changes in community resilience over time. additionally, future studies should focus on developing a comprehensive resilience framework that incorporates multiple dimensions of resilience—including social, institutional, environmental, and infrastructural aspects—beyond just economic resilience. declaration we,

(2009) point out that the massive social change may cause the second demographic transition. the second demographic transition refers to a shift from high fertility and mortality rates in the earlier demographic transition to lower birth rates and later marriage. according to rand corporation (2023), nearly 20 percent of russians are over 60, and that proportion is expected to continue to rise in 2023. this shift also coincides with the second demographic transition, such as delayed birth rates and longer life expectancy (rand corporation, 2023). figure 1: working-age population source:https://www.populationpyramid.net/russian-federation/2020/ source:https://www.populationpyramid.net/russian-federation/2050/ https://www.populationpyramid.net/russian-federation/2020/ https://www.populationpyramid.net/russian-federation/2050/ global sustainability research global scientific research 155 this shift has led to declining fertility rates and an aging population becoming more prominent, which poses challenges to russia's workforce and economic stability. in addition, internal migration is influenced by the political situation in russia. for example, russia's war with ukraine led to emigration of russian residents, as well as lower birth rates and higher death rates, which worsened the demographic outlook (centre for eastern studies, 2023). sinitsa (2019) also claims that a low birth rate will lead to a lack of labour in the workplace, and the working-age population will decline. thus, russia may face a population crisis that includes both an ageing population and a lack of labour in the future. this phenomenon will act a negative influence on domestic economic growth. in addition, the aging of the russian population reduces russia's ability to innovate and reduce its competitiveness in global industry. for example, the country's ability to recruit military personnel is limited by a decrease in the number of young people available for military service (ensemble ias academy, 2024). further more, russia's economic relations with other countries will be affected by these demographic trends. a shrinking domestic workforce in russia will rely more on immigrants to reduce labor shortages, especially in industries such as healthcare and technology (ensemble ias academy, 2024). given the country's economic stagnation and political tensions with neighboring regions, attracting foreign workers can be a challenge. in addition, an aging population will increase the financial burden on pensioners, which will strain public resources, leading to social discontent and unrest (ensemble ias academy, 2024). therefore, in international politics, russia's demographic problems will exacerbate its internal challenges and lead to political instability. in addition, a shrinking working-age population would limit russia's position in international trade, military influence, and geopolitical negotiations on a global scale (rand corporation, 2023). in short, russia's aging population and labor shortages will reduce its global competitiveness and reshape its role in international politics and trade. these demographic shifts pose long-term challenges that will drive changes in their foreign policy and economic strategies. therefore, government policy should be focused on enlarging the local labour market and improve the domestic economy to stabilize the society of russia. methodology several significant challenges have been identified to strengthen the workforce. vishnevsky (2009) points out the main challenges are the low fertility rates and high mortality rates. he suggests that these challenges that policymakers face are amplified by the unbalanced ageing population and shortage of the labour market. in this context, the ageing population and low fertility contribute to a heavy burden on the russian health care system and pension system (see figure 2). for example, in russia, the consolidated budget expenditure on the public health care system took up 3.6% of the total gdp, while the spending on private health care accounted for 4.2% of gdp in 2006 (vishnevsky, 2009). russia's policymakers should adapt to economic challenges in increasing public and private health care expenditure. that means the limitation of health care resources leads to the failure of lowering the mortality rate (vishnevsky, 2009). in addition, the growing demographic burden of a working-age population is another major challenge facing policymakers. (see figure 3). for example, in all the projected variables after 2017, the population burden will increase to 2022, by which time more people will be of working age in the first decade of the 21st century. according to sinitsa (2019), the increased demographic challenges are associated with the aging population and decreased labour force. this will lead to labour shortages and a delay in the retirement age. furthermore, the increased population burden means that the working-age population faces serious economic challenges, resulting in a significant decline in living standards (sinitsa, 2019). this will affect the elderly forced to limit consumption, contributing to the shortage of the domestic market. therefore, policymakers should consider the demographic global sustainability research global scientific research 156 and economic challenges in alleviating the shrinking labor market. russia's health care policies, past and present, still face challenges. popovich et al. (2011) explained that the russian healthcare system continues to evolve, but inefficient allocation of funds and urban-rural disparities remain. they showed that increased resources from a stable economy have enabled targeted health programs to be implemented, but public health spending remains relatively low compared to available funding (popovich et al., 2011). compared to russia, switzerland and germany combine private and public healthcare components to strengthen medical services while controlling costs. these systems focus on balancing public health coverage with incentives for private providers to ensure that all populations, including those in rural areas, have access to quality care (who team, 2011). therefore, adopting this model could help solve the challenges facing rural healthcare in russia and improve efficiency. figure 2: spending on health care in russia as a share of gdp source: rosstat (2007) figure 3: the demographic burden of the working-age population in russia, 1990-2051 source: rosstat and author’s calculations global sustainability research global scientific research 157 several strategies have been proposed to address economic challenges caused by the ageing population and shortage of workforce in russia. in terms of the economic challenge, one strategy to solve these issues is to design a flexible and comprehensive employment pattern and establish relevant infrastructure to support it (sinitsa, 2019). more elderly participation in work with delayed pension and the encouraged demographic policy for improving fertility rate can alleviate the labour market shortage (sinitsa, 2019). for example, according to vishnevsky 2009), the russian government subsidies families with more children. this subsidy can be used to purchase residential property, improve children's education, and support mothers' retirement pension. in addition, in 2018, russia passed a pension reform that raised the retirement age from 60 to 65 for men and from 55 to 60 for women (world bank, 2019). full implementation is planned for 2028 and 2034 respectively (world bank, 2019). furthermore, policies to promote longer retirement include workplace adaptation for aging groups, lifelong learning programs, and incentives for employers to hire aging groups (world bank, 2019). the second strategy is to develop a comprehensive and effective migration policy (sinitsa, 2019). this is because economic opportunities and other forced factors can attract talents or skilled migrants to enlarge the russian labour market. economic migration is accepted and integrated into the russian labor market. this measure can reduce the social burden due to demographic changes (sinitsa, 2019). according to (centre for eastern studies, 2023; rand corporation, 2023), migration, particularly from central asia, has been a key strategy to reduce labor shortages in industries such as construction and agriculture. however, migration can also lead to unstable employment, limited legal protection and barriers to the integration of migrants. immigration policies could provide a more stable workforce, but current measures are often inadequate due to inconsistent implementation and bureaucratic obstacles (centre for eastern studies, 2023; rand corporation, 2023). moreover, strong antiimmigrant sentiment in russian society is a long-standing problem. according to human rights watch (2024), there is a high level of public dissatisfaction with immigration, due to the competition for jobs and cultural differences. as a result, xenophobic attitudes in russian society have also led to discriminatory behavior in society. for example, arbitrary detention and fines of migrants, even if their documents are legal, hinder the effective integration of migrants into russian society and the labor market (human rights watch, 2024). therefore, arbitrary detention and fines of migrants not only violate their human rights, but also undermine russia's international standing on issues of equality and justice (human rights watch, 2024). in the short term, the policy can ease pressure on russia's pension system. however, extending the working life of older people could also increase government spending on pension spending, especially if it leads to higher administrative costs of managing pensions (sinitsa, 2019). in addition, older workers are less productive than younger workers, which could limit overall economic growth. furthermore, the family subsidies for fertility can directly raise household incomes and encourage higher fertility rates. however, these measures could strain the budget in the short term and could lead to higher government deficits if not accompanied by tax increases or other compensatory fiscal measures. in the long term, encouraging immigration and integrating skilled foreign workers into the labor market can provide a long-term solution to labor shortages. by attracting young and skilled workers, russia has the potential to slow the decline in its working-age population. the influx of workers could provide a tax base to support russia's aging population, ensuring that the social welfare system remains sustainable over time (sinitsa, 2019). however, long-term integration can bring social challenges, such as potential tensions between migrants and native populations, which requires investment in social programs to ensure smooth integration and prevent social fragmentation. global sustainability research global scientific research 158 results and discussion the demographic transition model of the russian federation is inclined to the mid-second stage with a gradual increase in birth rates, based upon the interaction of various mechanisms (van de kaa, 1987, as cited in lu & keller, 2016). however, demographic issues should be concerned from multiple parts. the russian government has strongly focused on introducing external migrants to substitute the gap of the declined natural birth. however, the fundamental human rights of numerous immigrants are unlikely to be guaranteed due to a lack of political regulations (kubal, 2019). simultaneously, wang et al. (2019) assert cultural conflicts and increased competitiveness in labour markets will further exacerbate the conditions of vulnerable migrants with exclusion and discrimination. on the other hand, russia is the second-largest receiving country, followed by the u.s (kurbatova & yankovsky, 2016). russia has a long internal migrant history. semenov (2019) points out that the majority of the populations in siberia are migrants, which means migration is not a new strategy but has acted for many years. however, evidence demonstrates 11 million illegal and undocumented immigrants in russia by 2020, compared with 10.7 million in the u.s. (agnieszka & alejandro, 2020). that means the russian government would face more social disturbances attributed to untraceable illegal transactions among those unregistered immigrants (wang et al., 2019). according to sinitsa (2019), additional challenges would continually exacerbate the demographic burdens. illegal immigration in russia poses a multifaceted challenge, influencing both domestic stability and its relations with neighboring countries. in addition, millions of illegal immigrants are estimated to make up a significant part of the russian workforce, but they work in unstable conditions, often exploited by employers and marginalized in local communities (carnegie endowment for international peace, 2023). this puts pressure on public services and increases anti-immigrant sentiment and the racial discrimination and social unrest. however, this migration policy has also increased tensions with neighboring countries, especially those in central asia and eastern europe, whose migration often creates economic and social challenges for sending countries (radio free europe, 2020). in terms of employment perspective, sinitsa (2019) asserts numerous migrants will burden the local labour market, leading to a high proportion of nonworking generations. statistics project the unemployed people of all ages will rise to 118% by 2025 and continually increase by 123% in 2035 (sinitsa, 2019). insufficient and asymmetric employment will continually exacerbate russian social burdens. in this regard, evidence estimates that roughly 60,000 citizens prefer to emigrate due to the competitive labour market. the russian government had reduced the immigration quotas to alleviate this issue while there is no efficiency (mihaylova, 2017). compared to russia, germany's 2020 skilled migration act simplifies visa procedures for non-eu workers with qualifications in the healthcare sector (federal ministry of the interior & building and community, 2023). by combining immigration policy with the needs of the labor market, germany has effectively addressed the labor shortage caused by an aging population. in addition, germany has invested heavily in programs such as language training and professional certification (deutsche welle, 2019). these measures ensure that migrants are able to integrate into society and contribute economically. conclusion as several challenges mentioned above regarding economic burdens and migration selection, policymakers should consider such determinants based on current demographic patterns. motivating the birth fertility rate continually is the top priority of the russian government. nina et al. (2020) perceive that the government should encourage all females of reproductive age to breed children, particularly the young generations. for the government, then, the strategy of state aid should be a targeted subsidy rather than a blanket subsidy, which global sustainability research global scientific research 159 effectively provides more economical and political support to families having more than two children. for example, providing accessible and affordable childcare facilities can ease the burden on working parents and encourage them to have more children. in sweden, this country has successfully implemented a system of subsidized child care, which has led to higher fertility rates (andersson et al., 2011). therefore, russia could invest in a nationwide network of affordable child care centers to support working families. when it comes to migration, kurbatova and yankovsky (2016) claim medical examination should be the necessary migration procedure when immigrants enter. they also point out that professional medical specialists would be in demand to search the genetic ancestry of migrants. thus, medical tests will track the origins of immigrants to avoid hereditary diseases. as regards immigration management, khoreva et al. (2018) indicate the migration procedure need to strengthen coordination between the central and local authorities associated with migration management. as for temporary migrants or vulnerable groups, it is feasible for the regional migration department to permit registrations. immigration registration thus should tend to be systematized and categorized. compared to russia ,germany combines immigration with a "dual education" system, where migrants can take part in vocational training programs while working (oecd, 2022). this model matches migrants' skills with local industrial needs, helping them integrate into the workforce. similarly, russia can offer vocational training programs for migrants, allowing them to obtain certificates and work experience. in the aspect of employment, mihaylova (2017) illustrates that russia’s new concept of the state migration policy in 2015 (csmp) should focus more on targeted migrants strictly and selectively. however, khoreva et al. (2018) claim enhancing national economic diversity and international cooperation is a feasible approach. for example, the china-russia bilateral trade has stimulated e-commerce development, which provides females and the elderly online service works. therefore, the development of economic strength will be a necessary consideration to militate population pressure and face the projected decline population of working-age generations by 2050. in a conclusion, in terms of long-term benefits, fertility inventive policies can boost workforce growth. encouraging a higher birth rate could help maintain a stable labour market in the long run and reduce pressure on pension systems (vishnevsky, 2009). in addition, increasing the labor force through immigration helps to increase the funding of social welfare and ensure the long-term stability of pension and health care systems in russia. for example, canada has attracted and integrated skilled migrants, which demonstrated the fiscal benefits of a growing working-age population (cic news, 2023). declaration acknowledgment: n/a funding: n/a conflict of interest: no conflict of interest ethics approval/declaration: yes consent to participate: yes consent for publication: yes data availability: be available from the author global sustainability research global scientific research 160 authors contribution: 100% references andersson, gunnar, and ann-zofie duvander. “family policy and fertility in sweden.” european journal of population 27, no. 2 (2011): 185– 204.https://www.researchgate.net/publication/228731893_family_policies_and_fertility_in_sweden centre for eastern studies (osw). 2023.

(2) technological innovation, industrial structure upgrading and risk management are important channels through which green finance can affect economic resilience. (3) in the process of green finance enabling economic resilience, there is a nonlinear impact on economic resilience and a significant threshold effect. (4) the impact of green finance on enhancing china's macroeconomic resilience is spatially heterogeneous, and the promotion effect is more significant in the provinces with high economic development level. the government should encourage and support green finance industries which will then support the sustainable and healthy development of china's economy and environment. keywords: green finance; economic resilience; gmm difference; mediating effect; multiple threshold effect introduction with the outbreak of covid-19, economies around the world have experienced strong negative reactions such as stagnation or even regression of economic development, rapid rise in unemployment, decline in overseas investment, decrease in cross-border e-commerce trade and changes in commodity prices, which have led to a serious decline in the resilience of the world macro economy. as the wave fades, so does the problem of how to reshape the world economy. economic resilience is an important manifestation of an economy's resistance to shocks, resilience, restructuring capacity and innovation and development capacity aftershocks. compared with other countries, china, as the world's second largest economy, has played a key role in the process of reshaping the global sustainability research global scientific research 63 world economy in the post-epidemic era and achieved the first positive economic growth, which further demonstrates that china's economy has strong potential development space and strong economic resilience. the report to the 20th national congress of the communist party of china (cpc) stressed the importance of green finance, raising the building of a green financial system to a national strategy and attracting more capital to the green sector. by optimizing resource allocation, improving carbon emission reduction efficiency and reducing financial risks, green finance provides strong support for promoting economic transformation and upgrading and achieving sustainable development. sustainable development is broadly defined as development that meets the needs of present generations without jeopardizing the ability of future generations to meet their needs. with the continuous changes of the times, the content and connotation of sustainable development are gradually refined, and there are more detailed requirements in ecology, energy and environment.wang et al. (2016) argued that green finance promotes sustainable economic development by optimising resource allocation and promoting economic restructuring.yao et al. (2023) found that green finance significantly enhanced china's macroeconomic resilience, especially in terms of its ability to cope with shocks, organisational coordination and innovation and transformation.however, the research on the impact and mechanism of green finance in regulating china's macroeconomic resilience is still relatively insufficient. based on the panel data of 30 provinces in china, this study uses the gmm difference model to explore the impact of green finance on china's macroeconomic resilience, and further analyzes the mediating effect, threshold effect and spatial heterogeneity, to provide a scientific basis for formulating and optimizing relevant policies. the rest of the study is as following. chapter two summarizes the literature of this study and hypothesis. chapter three discusses the methods and models used in this study. in chapter four, we present concrete empirical results and conclude our work in chapter five. literature review research on the measurement of economic resilience the definition of economic resilience is still not in consensus. wan (2017) used gdp to measure economic resilience from three aspects: the rise and fall of the overall economy, the trend comparison before and after the shock, and the external impact model. tan (2020) using economic maintenance and restorative measures such as regional economic resilience. briguglio et al. (2006) extended economic resilience research elaboration to the area, choose 86 countries and regions, building contains macro, government regulation, social operation and four dimensions of market allocation of index system to measure the economy toughness. martin (2012) chose the measurement form of a single index, and used the change of the number of employees in a place before and after the shock as the measurement of economic resilience. brakman et al (2015), giannakis and bruggeman (2017) used the gdp of a place or the unemployment rate to construct a reverse indicator to replace the variable of the number of employees. polese (2015) studied the economic resilience in urban research, and found that highly educated human resources, rich and vast market environment, multi-form structure and other aspects were the key factors affecting the development of urban economic resilience, that is, they were used as the screening criteria for measurement indicators. doran and fingleton (2018) examined direction to expand into the space, based on law of verdun is hit with the fact that state economic system status difference, from the angle of view of the differences in size and economic recovery measure economic resilience; ubago et al. (2019) measured the economic resilience of the country as a whole from the three perspectives of industry, human resources and capital. global sustainability research global scientific research 64 analysis of the impact of green finance on china's macroeconomic resilience at present, researches on macroeconomic resilience have not yet reached a consensus. first of all, the definition of macroeconomic resilience varies from each other. wan (2017) used gdp to measure economic resilience from three aspects: the rise and fall of the overall economy, the trend comparison before and after the shock, and the external impact model. tan juntao (2020) using economic maintenance and restorative measures such as regional economic resilience, briguglio et al. (2006) to economic resilience research elaboration to the area, choose 86 countries and regions, building contains macro, government regulation, social operation and four dimensions of market allocation of index system to measure the economy toughness; martin (2012) chose the measurement form of a single index, and used the change of the number of employees in a place before and after the shock as the measurement of economic resilience; brakman et al (2015), giannakis and bruggeman (2017) used the gdp of a place or the unemployment rate to construct a reverse indicator to replace the variable of the number of employees; polese (2015) deeply studied the economic resilience in urban research, and found that highly educated human resources, rich and vast market environment, multi-form structure and other aspects were the key factors affecting the development of urban economic resilience, that is, they were used as the screening criteria for measurement indicators; doran and fingleton (2018) will research direction to expand into the space, based on law of verdun is hit with the fact that state economic system status difference, from the angle of view of the differences in size and economic recovery measure economic resilience; ubago et al. (2019) measured the economic resilience of the country as a whole from the three perspectives of industry, human resources and capital. the definition of economic resilience is relatively unified. it measures the ability of national and regional economic systems to withstand external shocks, such as the ability to resist disturbances, the ability to restore and maintain the original state, and the ability to enhance public security and maintain social order. moreover, economic resilience does not exist as an independent individual. it is closely related to a region's system, culture, science and technology, society and other aspects. it is the ballast stone of the resilience system and the barometer of the healthy and sound development of the economic system. in economic measure of resilience research, specific divided into use the single index such as gdp and employment measure, the fact that state compared with hit condition difference method, and contains the ability, the angle of the composite index measure method. is common among them, the more complex we measure method, related research covers the macro micro level, the internal influence mechanism, pratt &whitney financial doberman, mediation effect, space, etc., and for how to improve the economic resilience, how to shrink regional economic resilience differences provide advice. in this paper, economic resilience is defined as the ability to cope with shocks, the ability to organize and coordinate, and the ability to innovate and transform. adhere to the green sustainable development in our country, developing green finance, green finance in implementing the green development, boost the development of environmental protection industry, improve the pollution treatment system and played an important role in governance. green financial development to optimize the capital of the guidance, to further enhance china's macroeconomic resilience to promote economic development in high quality. this study will from two aspects of direct effects and indirect effects (see research design figure1.) green financial effect on our country's macroeconomic resilience theory mechanism. meng et al. (2023) constructed a high-quality economic development index and a green finance index, and found that green finance can significantly promote high-quality economic development, enhance technological innovation, promote industrial structure upgrading, and help enhance the impact of green finance on high-quality economic development. li et al. (2023) empirically found that green finance can improve the economic resilience of the region and have a positive impact on the economic resilience of the surrounding regions through spatial spillover effect through the construction of spatial dubin model. yao et al. (2023) constructed an evaluation index system of green finance and macroeconomic resilience, and based on the system gmm model and the mediating global sustainability research global scientific research 65 effect model, confirmed that green finance development can significantly improve china's macroeconomic resilience; shi et al. (2022) argued that green finance can promote high-quality economic development, but there is a nonlinear relationship between the two and there is a threshold effect. wen et al. (2022) argued that green finance affects high-quality economic development by supporting green innovation. song (2023) further demonstrated the positive role of green finance in promoting economic resilience through grey correlation analysis.liao (2024) pointed out that the realization of sustainable development goals cannot be achieved without the help and support of green finance, which can be regarded as a driving force for sustainable development from the perspective of economic development, social progress and ecological civilization optimization.however, as far as current research is concerned, the evaluation indicators of green finance and economic resilience are relatively simple and simple. analysis on transmission channels of green finance on china's macroeconomic resilience many scholars examined the green finance impacts as well as the transmission channelsthrough which that can affect economic resilience. wang et al. (2020) found that green finance enhances regional economic resilience by promoting industrial transformation. green finance can provide financial support for environmentally friendly and sustainable industries, so that these industries have more complete green innovation technology and can adapt to market changes and needs. liu et al. (2021), taking china's provincial panel data from 2010 to 2019 as an example, verified that green finance effectively promoted high-quality economic development through three ways: enterprise technology innovation, industrial structure upgrading and green consumption; xia et al. (2023), based on the fixed effect model, demonstrated that green finance can significantly promote corporate green innovation by promoting corporate technological innovation; zhang et al. (2023) believed that the upgrading of industrial structure played a significant mediating effect in the process of green finance improving the efficiency of green economic development. yao et al. (2023) empirically concluded that green finance promotes industrial upgrading and technological innovation to improve economic resilience. in the process of achieving the goal of sustainable economic development, green finance plays a very important role as a "booster". the progress of the economy needs the assistance and guarantee of green finance, especially the value and role of green finance should be affirmed from the perspective of "green economy" development. in recent years, the rapid development and continuous progress of china's economy have had a profound direct and potential impact on the environment. the comprehensive strengthening of environmental protection work has also become an urgent key task. there is a very close connection between the proposal of the concept of "green finance" and the construction of an "environmentally friendly" economic development pattern. the impact of the continuous rise of green finance on sustainable economic progress can be analyzed from two aspects: first, it vigorously promotes the progress of green consumption; second, it realizes the continuous tilt and transfer of social resources towards green industries. the development of green finance has fundamentally replaced the coverage of the economy in the fields of green development and low-carbon development. while enterprises fulfill their responsibilities for green development, they also have more financial support and guarantees. especially in the macro environment where market entities are developing towards diversification, financial institutions have shown more confidence and stronger motivation in the development of green finance. the comprehensive creation of a coordinated and interactive pattern between the financial market and the carbon market has also provided space for the value and role of green finance to be exerted and developed. first, green finance helps to optimize the allocation of resources. the traditional economic development model tends to over-rely on industries with high energy consumption and high pollution, leading to over-exploitation of natural resources and environmental damage. the rise of green finance provides an opportunity for funds to flow to environmentally friendly and sustainable development areas. by financial institutions providing financial tools, global sustainability research global scientific research 66 such as green loans, green bonds, funds can be more effectively guide to clean energy, energy conservation and emissions reduction, recycling economy and green industry, promote the optimization of economic structure and transformation. this will not only help reduce environmental pressure, reduce energy consumption and pollutant emissions, but also promote the development of new technologies and industries, foster a more competitive industrial chain and enhance the resilience of the economy. secondly, the guiding role of green finance can also promote the development of green consumption. while providing financing for green projects, green finance also promotes the supply and awareness of green products and services. through the green standards, evaluation and information disclosure system established by financial institutions, they can provide investors with relevant information about green products and evaluate their environmental friendliness and sustainability. this provides consumers with a clearer choice, enabling them to consciously choose environmentally friendly and low-carbon products and services. this green consumption shift will not only help change the traditional consumption pattern of high energy consumption and high emissions, reduce resource waste and environmental pressure, but also promote new green industries and job creation, and promote sustainable economic development. based on this, hypothesis 1 is proposed in this paper. hypothesis 1: the development of green finance can from "the ability to cope with shocks", "the organization and coordination ability," and "innovation transformation ability three aspects significantly increased the macroeconomic resilience. analysis of the multi-threshold effect of green finance on macroeconomic resilience in china the existing literature discusses very fewer about the threshold effect of green finance on macroeconomic resilience. xiao et al. (2023) used the dynamic generalized panel model method to conduct nonlinear impact analysis to explore the mechanism of green finance promoting high-quality economic development through green technology innovation, and analyzed the regulating effect of green finance on the relationship between green technology innovation and high-quality economic development. the results show that gte plays a partial intermediary role between different dimensions of green finance and high-quality economic development, among which gte plays the strongest role in promoting high-quality economic development through green securities, followed by green credit and green insurance. zhang et al. (2020), taking the yangtze river delta core urban agglomeration as an example, used panel data model to study that green finance and industrial structure upgrading are the direct driving forces for high-quality economic development; industrial structure upgrading plays a partial intermediary role in the process of green finance promoting high-quality economic development, and is an important intermediary path, but the moderating effect is not significant. ma (2018) believed that industrial structure, energy structure and transportation structure were the economic causes of severe pollution and large amount of carbon emissions in china. therefore, it is necessary to change the polluting economic structure, and the main way to change the economic structure is to change the investment structure and increase green investment. we should accelerate the construction of green financial system through 12 channels, such as establishing green development fund, supporting the development of green credit, establishing green guarantee mechanism, and building incentive mechanism of green finance, so as to improve the return on investment and financing availability of green projects, and reduce the return on investment and financing availability of polluting projects. since the implementation of the western development policy, chen et al. (2018), the western region has made full use of its resource advantages and latecomer advantages to actively undertake the industrial transfer in the central and eastern regions, and the industrial structure has been optimized to a certain extent. as the most important ecological barrier and ecologically fragile region in china, the western region should abandon the development concept of "pollution first, treatment later", promote the optimization and upgrading of industrial structure with green finance, and achieve green development and high-quality economic development. on the one hand, green finance can promote global sustainability research global scientific research 67 industrial upgrading. the emergence of green finance, guided by innovation, environmental protection and sustainability, provides financing support for the development of strategic emerging industries and high-tech industries. these industries involve fields such as clean energy, new materials and new energy vehicles, and are characterized by high added value, high-tech content, low pollution and low energy consumption. through green loans, bonds and funds provided by financial institutions, social funds can be transferred to these sectors to accelerate the upgrading and transformation of the industrial structure, narrow the technological gap with developed countries, and improve the level of the industrial chain and its core competitiveness. in this way, economic development can be accelerated, while the impact on the environment and high consumption of limited resources can be reduced, and economic resilience can be improved. on the other hand, green finance can promote technological innovation. the introduction of green finance can provide financial support and market promotion for innovative technologies such as new energy and environmental protection technologies. research and development in these fields can not only reduce energy consumption and pollution, promote the development of environmental protection industry, but also foster new industries and drive the development of innovation. at the same time, financial institutions can also according to the green standards, assessment and disclosure of financial and non-financial information, form the ability of identification, risk evaluation and management of green, provide better protection for the technology innovation. such green financial innovation not only helps to optimize the allocation of resources and promote economic development, but also speeds up the process of scientific and technological innovation and improves the level of industrial chain and market competitiveness, thus enhancing the innovation, resilience and sustainability of the economy. based on this, hypothesis 2 is proposed in this paper. hypothesis 2: technological innovation and industrial structure upgrading act as intermediaries to affect the impact of green finance on china's macroeconomic resilience. green finance can promote the development of low-carbon and clean energy industries and promote the transformation and upgrading of economic structure. by guiding and supporting the development of green industries, the economy can improve its resource utilization efficiency and reduce its dependence on traditional industries with high pollution and high energy consumption, thus enhancing macroeconomic resilience. secondly, green finance can provide long-term and stable financial support to help enterprises make environmentfriendly investments and innovate. this not only helps to reduce environment pollution and resource waste, can also enhance the enterprise the competitive ability and sustainable development ability. this non-linear impact can create a virtuous cycle between economic growth and environmental protection. in addition, green finance can also promote the construction of ecological civilization, improve the ecological environment quality, improve the people's feeling and happiness. this kind of nonlinear positive affect can promote social stability and sustainable development, macroeconomic resilience to provide strong support for our country. based on this, hypothesis 3 is proposed in this paper. hypothesis 3: as threshold variables, technological innovation, industrial structure upgrading and risk management make the impact of green finance on economic resilience have nonlinear characteristics. spatial heterogeneity analysis of green finance on china's macroeconomic resilience there are also limited studies about the spatial differences on green finance impact on economic resilience. xu et al. (2018) argued that green finance can through the enterprise capital formation mechanism, the signal transmission mechanism, the mechanism of feedback and credit has influence industrial structure, the empirical results show that the green finance mainly through direct funds to influence industrial structure, and regional differences, the eastern region because of its own resources advantage, the western region because of the policy advantages, green credit global sustainability research global scientific research 68 has significant effects on industrial structure upgrade, the effect is not obvious in the central region. du and zheng (2019) argued that green finance in developed regions played a greater role and had a significant effect on carbon emission reduction. zeng (2021) set in the new crown pneumonia outbreak, from two aspects: resistance and resilience of the outbreak of the influence of the development of china's regional economic resilience, found in different quarter period, resistance have different strength, resilience, performance, the provinces domain also presents the different strength of economic resilience. cheng (2022) found empirical green finance in the eastern economic resilience, big cities to promote effective, economic resilience to promote small and medium-sized cities of the midwest, the effect is not significant, namely exists heterogeneity; deng and liu (2023) believed that from the perspective of the central and western regions, the role of green finance in promoting the high-quality economic development of the central and western regions was significantly higher than that of the eastern regions. shang et al. (2023) used dagum gini coefficient and variance decomposition to reveal that the overall level of green finance in china is not high from the perspective of north-south space and structure, and the southern region is higher than the northern region. du et al. (2023) points out that the green financial development imbalance in our country, far from the green level of financial development in our country overall. song (2023) empirically found that there is a significant spatial correlation between green finance and economic resilience through the construction of spatial matrix. most of the existing research focuses on the independent analysis of the correlation between green development and economic development, but the spatial research on the national scale is relatively scarce. firstly, regional natural resource endowments and environmental conditions are important factors affecting the role of green finance. there are differences in resource distribution and environmental status in different regions, which lead to different effects of green finance in different regions. on the one hand, in areas with rich resources and good ecological environment, such as coastal areas and ecological reserves, the application of green finance can better promote the rational use of resources and environmental protection, and improve the resilience of the economy. on the other hand, in areas with poor resources and serious environmental pollution, the application of green finance may face greater challenges and its effect on improving economic resilience may be relatively weak. second, the region's industrial structure and development level will also affect the role of green finance. there are differences in the industrial structure of different regions. some regions may rely more on industries with high pollution and high energy consumption, while other regions may have realized the optimization of industrial structure and green transformation. therefore, the application effect of green finance in different regions will also be different. for those regions that rely on industries with high pollution and energy consumption, the introduction of green finance can promote industrial transformation and upgrading in these regions and improve their resilience. however, for those regions that have optimized their industrial structure, the application of green finance has a relatively small effect on improving their resilience. in addition, the regional policy environment and the level of financial market development will also affect the role of green finance. there are differences in policy support and financial market development levels in different regions, which will directly affect the development and application of green finance. some regions may have established a sound green finance policy and regulatory framework, providing better financial services and support, and green finance may have better application effects in these regions. while some regions may lack relevant policies and financial market development, and the application of green finance may face more difficulties. based on this, hypothesis 4 is proposed in this paper. hypothesis 4: green finance function in the macroeconomic resilience of spatial heterogeneity. global sustainability research global scientific research 69 methodology data and variables considering the availability of data, due to the tibet autonomous region of the data in china 2011 years ago and the existence of a large number of the problem of the missing, so in this paper, based on 2011-2022 data of 30 provinces and autonomous regions municipalities directly under the central government data sample space for research. the data on environmental pollution, infrastructure, human capital, resource endowment, technological innovation and industrial structure upgrading come from china statistical yearbook, china financial statistical yearbook, financial basic data center of the people's bank of china, china research data platform, china public policy and green development database and wind database. the data related to the construction of the green finance evaluation system are from the global green finance big data platform of central university of finance and economics, the websites of the ministry of science and technology, the national bureau of statistics, the people's bank of china and other authoritative statistical yearbooks, including the national and provincial statistical yearbooks, environmental status bulletin and some professional statistical yearbooks. "china financial yearbook", "china statistical yearbook of science and technology of the china energy statistical yearbook of china agricultural statistics yearbook" china industrial statistics yearbook "statistical yearbook of china's third industry. some missing values were obtained by interpolation method. one core explanatory variable, one core explained variable, two mediating variables and four control variables were selected. explained variables economic resilience evaluation index (ecores, er), according to the existing literature, there are two main methods to measure economic resilience: the first is the single index method, which is used by chen et al. (2020) to define regional economic resilience based on the growth rate of the actual gross domestic product (gdp) of each province. the second method is to construct a comprehensive index system for measurement. the results reflected by the single index method vary greatly according to the changes of selected indexes, which cannot fully reflect economic resilience. in this study reference yao et al （2023）method, on the basis of using the "ability to cope with shocks", "organization coordinated ability", "innovation transformation ability" three secondary index evaluation system to build economic resilience, the ability to cope with shocks "refers to the object of economy in the face of shock response capacity, "organization coordinated ability" refers to the object of economy in the face of economic recession on technology updates, capital allocation, and labor to make the new configuration, transformation of "innovation ability" refers to the object of economy after a hit from the outside world, choice of transformation of the development of new methods and technology ability. the entropy method is used for calculation. the evaluation system is shown in table 1. which is obtained by entropy value method "ability to cope with shocks" weight 0.218, organization and coordination ability, weight is 0.347, "transformation of innovation ability" weight is 0.435. the weight coefficients are shown in table 2. core explanatory variables green finance level index (gfi) is based on the green finance evaluation system constructed by zeng et al. (2014), which includes green credit, green insurance, green securities and green investment. this paper constructs a green global sustainability research global scientific research 70 finance level system (see table 3) from seven levels: green credit, green investment, green insurance, green bond, green support, green fund and green equity. fyone, 2020), using the entropy topsis method of green samples in 31 provinces, cities and autonomous regions municipalities directly under the central government to the financial index as an evaluation of local green financial level measurement data. entropy weight topsis method is a method formed by the combination of entropy weight method and topsis model. it is a mathematical method used to judge the dispersion degree of an index. its

0.435 first, the original matrix is forward transformed, that is, all indexes are transformed into very large indexes. then, the matrix standard is forward transformed to eliminate the influence of different index dimensions. suppose that there are n evaluation objects and m evaluation indicators (all of which have been positive), the positive matrix is as follows: 𝑋 = [ 𝑥11 𝑥12 𝑥13 𝑥14 … 𝑥1𝑚 𝑥21 𝑥22 𝑥23 𝑥24 … 𝑥2𝑚 𝑥31 𝑥32 𝑥33 𝑥34 … 𝑥3𝑚 ⋯ ⋯ ⋯ ⋯ ⋯ ⋯ 𝑥𝑛1 𝑥𝑛2 𝑥𝑛3 𝑥𝑛4 … 𝑥𝑚𝑚 ] after that, the normalized matrix of each element is z, where each element in z is:.𝑧𝑖𝑗 = 𝑥𝑖𝑗/√∑ 𝑥𝑖𝑗 2𝑛 𝑖=1 finally, we first determine the most value for subsequent calculation. to define the maximum value: 𝑍𝑚𝑎𝑥 = (𝑍1𝑚𝑎𝑥, 𝑍2𝑚𝑎𝑥 , … , 𝑍𝑚𝑎𝑥) = （𝑚𝑎𝑥{𝑧11, 𝑧21, 𝑧31, … , 𝑧𝑛1},𝑚𝑎𝑥{𝑧12, 𝑧22, 𝑧32, … , 𝑧𝑛2},…𝑚𝑎𝑥{𝑧1𝑚, 𝑧2𝑚, 𝑧3𝑚,

and normalized. the greater the degree of dispersion is, the greater the influence of the index on the comprehensive evaluation is. the comprehensive evaluation system is as follows: global

intermediary variables technological innovation, industrial structure upgrading and risk management. green finance is to promote technological innovation, guide the flow of capital to the direction of scientific and technological innovation, develop advanced industrial technology, improve production efficiency, and achieve green and sustainable economic development. the technological innovation index of this study is measured by the expenditure of local finance on science and technology, and the upgrading of industrial structure is an important reflection highlighting the capital flow and the reallocation of production factors among different industries. the upgrading index of industrial structure in this study is measured by the ratio of the total output value of the local tertiary industry and the secondary industry. risk management ability is an important embodiment of capital allocation, which is measured by the ratio of working capital to assets in this study. control variables in this study, environmental pollution, infrastructure, human capital and resource endowment are selected as control variables and upgraded by referring to the calculation method of wang qizheng and zhu yingming. environmental global sustainability research global scientific research 73 pollution is measured by local financial expenditure on environmental protection, infrastructure is measured by local highway mileage, and human capital is measured by local resident population aged 14-65. resources endowment in terms of local electric power consumption. descriptive statistics

descriptive statistical analysis shows that this study evaluates the data of different variables so as to understand their distribution and relative differences. the standard deviations of economic resilience, green finance index, environmental pollution, infrastructure, human capital, and resource endowment are all smaller than the mean, and the absolute values differ greatly. the standard deviation data in the table are generally small, indicating that the distribution of sample data is relatively concentrated. in addition, except for human capital, the variance of other variables is small, indicating that the fluctuation degree of the data is small and the stability is high. global sustainability research global scientific research 74 econometric model system gmm model system gmm

specifically, in the impact of green finance on china's macroeconomic resilience, technological innovation and industrial structure upgrading as well as risk management ability as mediating variables show a full mediating effect in the impact of green finance on macroeconomic resilience. these results indicate that technological innovation and industrial structure upgrading as well as risk management capability play an important role in the process of green finance playing a role, which further strengthens our understanding of the relationship between these variables. the threshold effect empirically threshold effect test the results of this model are obtained under 300 bootstrapping (bs) sampling. for innovative technology, in a double threshold estimation, p value is 0.15, not through the test of significance, namely the model does not exist double threshold effect; in a single threshold estimation, f value is 65.83, significant under 1% level, the 95% confidence interval [6.5281, 6.5910], so the model is a single threshold, threshold effect analysis can be performed. for the upgrading of industrial structure, in a double threshold regression, p value is 0.00, f

influence of green finance on economic resilience due to differences in industrial structure upgrading is significantly positive: when the innovation level is lower than the first threshold value of 0.9396, the influence coefficient of green finance on regional economic resilience is 0.636, which is significant at the level of 5%; when the threshold variable between first threshold and second threshold value, the core explanation variables global sustainability research global scientific research 80 to explain the influence is positive significant, influence coefficient is 0.336, p value is 0.000, significant at 1% level; when innovation level is greater than the threshold value of 1.4491, the influence coefficient is 0.650, p value is 0.000, significant under 1% level. however, as the threshold value first increases and then decreases, the threshold variable has an optimal interval, that is, the threshold value is within [0.9574,1.4491]. at the same time, in order to intuitively present the regression effect and threshold effect, figure 1 is the threshold effect test diagram based on each threshold variable. figure 1. threshold effect test diagram robustness test of threshold effect the results of the robustness tests were all obtained under 300 bootstrapping (bs) sampling. for the threshold variables of technological innovation capability and risk management capability, both of them are significant at the level of 1% in the single threshold estimation, with 95% confidence intervals of [6.5281,6.5910] and [7.5013,7.5200], respectively. for industrial structure upgrading, in the double threshold estimation, the 95% confidence interval is [0.9116,0.9489] and [0.9272,0.9617]. therefore robustness model has a single threshold for threshold effect analysis. table 12 uses the method of deleting the control variable "human capital". from the regression results, it can be seen that the threshold values change weakly, which are 6.5809, 0.9396, 0.9574 and 7.5120 respectively. secondly, it can be seen from the observation coefficient that when the threshold variable is lower than or higher than the threshold value, the positive promoting effect of the growth unit of green finance development on economic global sustainability research global scientific research 81 resilience is improved compared with the regression results of the threshold benchmark, and the significance level does not change much. table12. robust regression results of threshold effect variables er ti uis rm ep 0.083*** (2.70) 0.046*** (1.85) 0.060*** (1.61)

research 84 this study uses four groups of sample data to pass the two-way fixed effect test, and the test results are as follows: table 15-18. among them, the central and eastern provinces are the most significant, followed by the eastern provinces, and finally the western provinces. it shows that the development of green finance has a positive promoting effect on local economic resilience, and the positive promoting effect is the largest in the central and the three eastern provinces, followed by the eastern region and the weakest in the western region. based on the analysis of the model conclusions, this study holds that different regions have different environmental resource endowments and basic economic development status, and the demand degree of green finance for environmental protection and sustainable use will also be different. the three provinces in central china and northeast china have rich natural resources, and due to the prominent environmental problems, such as soil erosion, the demand for green finance is relatively large. the eastern region has more perfect infrastructure related to green finance, and follows the principle of green and high-quality development. compared with the western region, the eastern region has more complete traditional financial and green financial systems, and more sufficient financial support, which can better play the positive role of green finance in promoting regional macroeconomic resilience. conclusions and policy recommendations using the relevant data of 30 provinces in china from 2011 to 2022, this paper examines the impact of green finance on china's macroeconomic resilience and the mediating effect of technological innovation and industrial structure upgrading. first, using the latest provincial data, this study proves that the development of green finance can greatly improve china's macroeconomic resilience and promote economic stability and sustainable development. secondly, this study verifies that technological innovation, industrial structure upgrading, and risk management, as mediating effects, can further enhance china's macroeconomic resilience. finally, green finance shows strong spatial heterogeneity in the process of promoting china's macroeconomic resilience. based on the above conclusions, this study puts forward the following policy recommendations: the development of green finance can significantly enhance china's macroeconomic resilience, especially in terms of coping with shocks. through diversified economic structure, efficient allocation of resources, risk management and reduction, green finance provides important support for sustainable economic development and resisting external shocks. by encouraging and supporting the development of green industries, green finance can promote the transformation of the economy to a low-carbon, environmentally friendly and sustainable direction, so as to reduce the vulnerability of the economy to specific industries or fields and improve the resilience of the overall economy to external shocks. through the support of green finance, environmental protection and sustainable projects can obtain more funds and investment, so as to promote the effective use and conservation of resources to cope with the shortage of resource supply and price fluctuations; by introducing green financial instruments, such as green bonds and green insurance, enterprises and financial institutions can better assess and manage risks related to climate change, natural disasters, etc., reduce the vulnerability of the economy, and improve the ability to withstand shocks. the development of green finance can significantly enhance the resilience of china's macro economy in terms of organizational and coordination capabilities. policy framework and standards, the participation of financial institutions, the establishment of multilateral cooperation and partnership can help improve the organization and coordination ability and promote the development of green finance, promote the sustainable development of economy, the efficient allocation of resources and risk management, improve the macroeconomic resilience and competitiveness. government to formulate and implement green financial policy, for example, to set up the green financial fund, make green bonds issue guidelines, etc., provide direction and specification for the development of green finance, organization and coordination of all parties. financial institutions such as banks, securities companies and insurance institutions promote the financing and investment of environmentally friendly and sustainable projects by providing green financial products and services. financial institutions participate in the green finance market to achieve effective global sustainability research global scientific research 85 allocation of resources and management of risks, and improve the resilience of the overall economy. all stakeholders, including governments, financial institutions, enterprises, social organizations and the public, should establish partnerships to jointly promote the development of green finance. for example, the government can provide policy support and market guidance, financial institutions can provide financing and risk management, enterprises can implement green projects, and social organizations and the public can provide supervision and participation. the development of green finance can significantly enhance the resilience of china's macro economy in terms of innovation and transformation capacity. through innovative economic model and transformation capacity cultivation, green finance can promote the economy to achieve innovative transformation, improve adaptability and competitiveness, and enhance the economy's ability to resist risks and sustainable development. enterprises and entrepreneurs should be encouraged to innovate in green technology, clean energy, environmental protection and other fields to foster new economic growth points and improve the economy's innovation and transformation capacity, to enhance macroeconomic resilience. through the support of green finance, enterprises can obtain funds and resources to promote the transformation towards environmental protection and sustainability. green finance can provide support services such as training and consulting to help enterprises improve their environmental management and sustainable development capabilities, so that they can better adapt to market changes and environmental requirements, enhance their ability to resist risks, and thus improve macroeconomic resilience. by innovating the ways and means of green financial development, guiding financial capital to help the new track of green development, can provide support for the sustainable development of more industries and industries in our country, promote the progress of green technology, and have a positive role in transforming green technology into actual results. at the same time, we should further adhere to and increase scientific and technological innovation, and encourage green finance participants to innovate in technology. financial institutions may set up a special department to financial product innovation, in order to satisfy the demands of enterprise technology innovation fund, the relevant government departments should strengthen the support of enterprise technology innovation, set up special funds or implement preferential tax policies, reduce the financing cost of enterprises, green technology innovation for enterprises to create a good financial environment. we should promote the resilience of the economy and form a replicable, promotable and sustainable green finance model. we will establish a sound green financial system, introduce capital into green and environmentally friendly industries with low energy consumption, promote sustainable and green economic development, increase economic growth potential and enhance economic resilience. at the same time, we will promote diversification of green products and accelerate the upgrading of green industries. with investment and financing support from green finance, traditional industries with high pollution and high energy consumption can be transformed and upgraded to green industries and clean technologies. the upgrading of industrial structure helps to improve the degree of resource utilization efficiency and environmentally friendly economy, reduce reliance on limited resources, improve the ability of the sustainable development of the economy. at the same time, the upgrade of industrial structure will also be able to develop new industries and jobs, to improve the toughness of the overall economy and innovation ability. we will further consolidate the macroeconomic system and strengthen economic integration and complementarity among regions. green finance for toughness at a higher level of regional economy region promoting effect is more effective and more prominent, the higher market openness of the eastern region will strengthen the green financial system innovation; in the resource-rich central region, it can mobilize social forces to promote the expansion of green finance financing scale; in the western regions along the belt and road, we can continue to increase investment in environmental governance with the help of preferential policies. the eastern region with developed green finance can guide the central and western regions to realize diversified green finance. under the effect of green finance on economic resilience, it can promote a virtuous cycle of economic resilience intensity, form a global sustainability research global scientific research 86 benign competition among various regions, build a high-level linkage system for green finance development, and subtly transfer the concept of green finance into the economic system. thus, it can better promote economic resilience and generate high-high aggregation effect. in general, it is necessary to maintain a stable macroeconomic environment, optimize the information sharing mechanism, promote the reasonable aggregation, efficient flow and balanced diffusion of resources, promote the coordinated development of regional economy, get rid of the development pattern of weak resistance, and form a virtuous cycle and spatial optimization. declaration acknowledgment: throughout the writing of this dissertation, i have received a great deal of support and assistance. i would first like

technology, hangzhou china corresponding author: name: hongmin liu. email: hmliu@zust.edu.cn received: 29 march, 2025, accepted: 31 may, 2025, published: 17 june, 2025 abstract in the face of volatile domestic and international market environments and rapid industrial evolution, the key to successful corporate globalization lies in how enterprises dynamically capture multiple windows of opportunity-institutional, technological, and demand-driven–through environmental scanning strategies. this process must align with organizations' dynamic capabilities to translate insights into decisive overseas expansion strategies that reconstruct value chains. through an exploratory case study of byd co., ltd. in shenzhen, this paper examines the application of opportunity window theory and dynamic capability theory in corporate globalization strategies. it investigates how enterprises identify optimal timing for internationalization and the critical importance of leveraging domestic and global environmental opportunities for overseas expansion. the findings reveal that enterprises' acute market insights enable windows of opportunity’s identification and responsiveness to international demands, meanwhile, the enhancement of dynamic capabilities is crucial in seizing these opportunities, transforming them into core competitive advantages, and ultimately bolstering corporate competitiveness, thereby ensuring the successful implementation of globalization strategies. keywords: new energy vehicles (nevs); environmental scanning; windows of opportunity; global expansion strategy; byd introduction with the escalating challenges of global climate change and environmental pollution, promoting green economic transformation and low-carbon development in the automotive industry has emerged as a shared objective among nations worldwide. in this context, new energy vehicles (nevs) have entered a period of rapid development due to their demonstrated advantages in reducing carbon emissions and energy consumption. governments globally have implemented incentive policies – including purchase subsidies, tax incentives, and free parking privileges – to stimulate nev adoption. concurrently, growing consumer recognition of eco-friendly transportation solutions has driven sustained market demand expansion. this dual momentum of policy support and environmental consciousness has positioned the nev sector as a critical pathway for achieving sustainable mobility and meeting international climate commitments. global sustainability research global scientific research 113 leveraging advantages such as a massive consumer market, comprehensive industrial categories, advanced power battery technology, efficient industrial chain systems, and holistic innovation capabilities, china's automotive industry has successfully executed its "lane-changing competition" strategy and achieved late-mover catch-up, while attaining significant progress in its "going global" initiatives(j.t.chen, 2023). driven by multifaceted factors including policy support, market demand, and corporate technological innovation, china's new energy vehicle (nev) industry has achieved remarkable developmental milestones, establishing a comprehensive industrial ecosystem with world-leading capabilities in core technologies such as battery systems, electric motors, and electronic controls. as domestic market saturation intensifies and competition escalates, chinese nev manufacturers are increasingly targeting international markets to pursue sustainable growth opportunities. as one of the earliest globalized industries worldwide, the automotive sector exerts strong multiplier effects on national economic development. it remains a critical battleground for international industrial competition and is frequently prioritized by late-developing nations as a strategic sector for technological catch-up efforts((j.t.chen, 2023). as a pioneering enterprise in china's nev sector, byd initiated its global strategic expansion as early as 1998. evolving from initial overseas deployments in battery and electronics businesses to subsequent commercial vehicle exports, and ultimately to its current phase of passenger vehicle globalization and overseas production capacity establishment, byd has demonstrated noteworthy accomplishments in global markets. however, international market expansion entails navigating multifaceted uncertainties, including market volatility, technological barriers, trade disputes, tariff fluctuations, international public relations challenges, and geopolitical dynamics. against this backdrop, an in-depth investigation into byd's strategic practices holds significant theoretical and practical value—particularly regarding how the enterprise leverages systematic environmental scanning strategies to identify opportunity windows arising from institutional transitions, technological innovations, and market demands, while synergizing these insights with organizational dynamic capabilities to formulate effective globalization strategies. this research paradigm offers critical insights into the operational mechanisms through which emerging market enterprises transform environmental uncertainties into competitive advantages during internationalization processes. byd was selected in this study, and a case study approach was employed to conduct an in depth analysis. it focuses on two core research questions: first, how environmental scanning and the windows of opportunity theory are interconnected to facilitate successful corporate internationalization; second, how the enhancement of enterprise dynamic capabilities, in the context of responding to opportunity windows, is transformed into core competitive advantages for global expansion, thereby supporting the implementation of a comprehensive internationalization strategy. compared to traditional quantitative research methods, the case study approach enables a profound exploration of specific practices and strategies during corporate internationalization. through a detailed examination of byd’s strategic evolution from product exports to full-spectrum globalization (including production capacity, technology, and brand expansion), this methodology vividly demonstrates the application of theoretical frameworks in real-world corporate operations. the innovation of this study lies in two aspects. first, it adopts a panoramic perspective on internationalization strategy research. unlike previous studies that focused solely on product exports or single-market expansion, this research comprehensively analyzes byd’s strategic deployments across multiple dimensions, including product globalization, overseas production capacity establishment, brand internationalization, and technology standardization. by systematically investigating byd’s holistic globalization strategy, the study fully reveals its developmental trajectory and strategic patterns in global markets, providing new perspectives and analytical frameworks for understanding corporate internationalization processes.second,the window of opportunity theory provides a theoretical framework for analyzing china's electric vehicle industry's "lane-changing competition" strategy and internationalization initiatives amid industrial transformation(wang jing，2024). the study constructs an analytical framework based on the window of opportunity theory. this framework explores how byd identifies global sustainability research global scientific research 114 changes in domestic and international institutional environments, technological innovations, and market demands through environmental scanning, captures potential opportunity windows, and strategically integrates its internal dynamic capabilities with external opportunities to formulate effective internationalization strategies. the framework not only enhances the understanding of byd’s successful globalization practices but also contributes new empirical evidence to the development of corporate internationalization theory. specifically, it demonstrates how enterprises align organizational adaptability with emerging market conditions, offering transferable insights for emerging market multinationals navigating institutional complexities and technological disruptions. the structure and organization of the paper includes the following sections: literature review (comprising conceptual framework, theoretical framework, and research commentary), research design (including research methodology, case selection and data sources, variable measurement, and case stage classification), case analysis and key findings, and finally, conclusion. literature review environmental scanning and windows of opportunity the concept of environmental scanning (es) was first proposed explicitly in aguilar’s book scanning the business environment in 1967, defining it as an organizational practice of systematically collecting and interpreting external environmental information to identify trends or transformative signals, thereby informing strategic decisionmaking. subsequent research has expanded beyond the focus of "external environment", with scholars refining the definition of environmental scanning through multiple lenses: a process for acquiring external information (aguilar f j, 1967; austerity, 1993; ngamkroeckjoti, 2008; zhong, 2013), a management method or tool (liao, 2008; haase h, 2011), a business intelligence mechanism integrating internal and external factors (bedford d, 2015), an information retrieval activities in business contexts (wang, 2004), a comprehensive environmental monitoring system for competitive intelligence(zhong, 2012). although scholars have varying emphases in their understanding of environmental scanning, the consensus lies in its role in serving strategic decision-making. this process involves thoroughly identifying and analyzing events, trends, as well as key drivers and subtle signals (maree c, 2010). by recognizing strategic threats and seizing opportunities in the external environment, and crafting corresponding strategic responses, enterprises can sustain their long-term competitive edge. the concept of "windows of opportunity" was first proposed by perez and soete (1988) to explain technological catch-up phenomena in latecomer countries. lee and malerba (2017) extended the concept to the industry level, categorizing it into three types: technological, demand, and institutional. the "demand window" specifically refers to emerging demand patterns, significant shifts in local demand, or business cycle changes (mathews, 2005), later described in research as the "market opportunity window". recent studies have shown that the alignment of opportunity windows with innovation strategies can significantly enhance the catch-up performance of latecomer enterprises, as evidenced by empirical research on chinese manufacturing firms (wu xiaobo, 2019). changes in external environments—technological, market, and institutional—create opportunity windows for companies to overtake through strategic maneuvers, necessitating organizational transformations to effectively respond to these windows. dynamic capabilities the concept of dynamic capabilities was first introduced by teece et al. (1997), defined as a firm's ability to integrate, build, and reconfigure internal and external competencies to address rapidly changing environments. the global sustainability research global scientific research 115 term 'dynamic' pertains to the firm's ability to adapt to shifting external conditions, ensuring the sustenance or reconstruction of competitive edges, whereas 'capabilities' underscore the pivotal role of strategic management in orchestrating and re-configuring organizational resources efficiently (peng, 2019). facing the complex and everchanging international market, enterprises need to leverage dynamic capabilities to integrate and reorganize internal and external resources, thereby adapting to market fluctuations and gaining a competitive advantage in global expansion. enhanced dynamic capabilities enable firms to perceive environmental changes more swiftly and comprehensively. high perception ability helps companies achieve precise self-positioning, enhance the conversion efficiency of opportunity windows, accelerate the process of technological catch-up, and consolidate international market position. (ma, 2023). subsequent studies have clarify dynamic capabilities into three dimensions: adaptive capability (a firm’s ability to identify and capitalize on emerging market opportunities), absorptive capability (a firm’s ability to recognize, evaluate and utilize the value of new external knowledge), and innovative capacity (a firm’s ability to develop new products or markets, through aligning strategic innovative orientation with innovative behaviors and processes) (wang et al., 2007). this tripartite framework, validated by chinese scholars, demonstrates strong representativeness and paradigmatic value. firms with heightened environmental sensing capabilities achieve rapid and thorough market cognition, thereby optimizing the translation of opportunity windows into strategic advantages. corporate global expansion strategy global expansion is a natural progression for companies with mature industrial and managerial capabilities, serving as a critical strategic pathway for achieving international growth and sustainable development. this is supported by the fact that companies aim to achieve financial growth, which often involves expanding into new markets, accessing top talent, and diversifying their supply chains. through overseas ventures, firms engage in technology complementarity and integration (shi et al., 2024), expand market boundaries, reduce over-dependence on single markets, enhance brand value and global influence, drive technological innovation and industrial upgrading. global expansion strategies are increasingly adopted as prudent responses to domestic market saturation and intensifying competition, aiming to consolidate global resources and strengthen supply chain resilience. however, the expansion of firms into international markets exposes them to a range of concentrated risks and environmental turbulence, encompassing geopolitical uncertainties, operational complexities, and the necessity for robust risk management strategies. (zhang, 2024), necessitating meticulous timing and unequivocal strategic clarity. to overcome these obstacles, enterprises must adopt environmental scanning strategies, systematically identifying and assessing international institutional changes, technological advancements, and shifting market demands, ultimately grasping the multidimensional nature of these dynamics. concurrently, by aligning these external opportunities with internal dynamic capabilities, firms can synthesize actionable global strategies, translating insights into phased implementation plans that harmonize organizational strengths with market realities. research commentary environmental scanning serves as a strategic antecedent to corporate decision-making. existing studies on environmental scanning primarily utilize quantitative methods to investigate its effects on firm performance and knowledge enhancement, albeit with scant exploration via mixed-methods approaches. while the windows of opportunity constitute a critical focus of environmental scanning, their identification hinges on organizational global sustainability research global scientific research 116 scanning behaviors. current research predominantly focuses on categorizing exploring opportunity window dimensions and analyzing their origins, the study pays scant attention to the integrated process of 'environmental scanning + opportunity window identification' as a continuous strategic mechanism. this study addresses this gap by adopting a case study methodology to incorporate opportunity window identification—underpinned by environmental scanning—into the strategic decision-making process of corporate global expansion. through the lens of opportunity window theory, we analyze three pivotal dimensions: timing of internationalization, target market selection and positioning strategies, strategic alignment between organizational dynamic capabilities and decision-making frameworks. by synthesizing these elements, this research elucidates the critical role of opportunity window theory in shaping effective global expansion strategies, offering a systematic framework to decode how firms transform environmental insights into actionable overseas deployment plans. research design research methodology considering the complexity of the above-mentioned research question, we conducted a longitudinal single-case study approach, justified by the following considerations: the research focuses on the procedural question of 'how new energy vehicle (nev) enterprises implement comprehensive global expansion strategies by capitalizing on opportunity windows', which naturally fits within the framework of case study methodology. the identification of internationalization timing and the phased, iterative process of seizing domestic and global opportunity windows require longitudinal analysis. an exploratory longitudinal single-case design serves to facilitate: tracking strategic choices throughout various phases of opportunity windows, performing a comprehensive multidimensional analysis of pivotal events, identifying the fundamental determinants that underpin successful corporate globalization. this approach enables a systematic deconstruction of how firms dynamically synchronize external opportunity recognition with internal strategic execution, providing granular insights into the nexus between environmental scanning, capability orchestration, and global market penetration. case selection and data sources byd co., ltd. in shenzhen was selected as the case subject of this study, adhering to the following criteria: a. typicality principle. byd epitomizes the successful globalization of chinese independent automotive brands. as a pioneer in china’s nev industry, it offers critical insights into identifying internationalization timing, capturing multidimensional opportunity windows, and achieving higher-tier growth amid the sector’s transition from laborintensive manufacturing to high-end, intelligent, and green transformation. b. data sufficiency principle. founded in 1994 and listed on the hong kong stock exchange (2002) and shenzhen stock exchange (2011), byd maintains high visibility globally, ensuring abundant publicly available data for rigorous analysis. to fulfill the triangulation requirements of case study methodology, this research integrates multi-source data: a. primary corporate disclosures: official website announcements, annual reports, and press releases from byd’s authorized media channels. b. academic and media publications: peer-reviewed articles from databases (e.g., cnki) and authoritative industry reports. c. third-party verification: public interviews, news reports (via baidu, zhihu), and analyses by consulting agencies. this multi-layered

case firm’s global expansion byd has cultivated its “product globalization” and “capacity globalization” strategies for over three decades, with critical milestones in its global industrial layout illustrated in figure 1. byd (build your dreams) was founded on november 18, 1994. in 1998, byd set foot in the netherlands with its inaugural overseas subsidiary, signaling the dawn of its global expansion. in 2010, byd embarked on a strategic shift towards 'electrifying urban public transportation', successfully venturing its commercial vehicles into international markets. in 2013, byd established its inaugural overseas electric vehicle manufacturing facility in california, usa, focusing on the production of the all-electric bus model k9. in 2021, byd chose norway as its european launchpad for passenger vehicle exports. in march 2023, the company held a groundbreaking ceremony for its first overseas passenger vehicle production base in thailand. by december of the same year, byd announced plans to construct a new energy vehicle (nev) production base in szeged, hungary, progressively securing a strategic foothold in the global passenger vehicle market. global sustainability research global scientific research 118 figure 1: key milestones of byd’s global industrial expansion from its initial battery product exports in 1998 to achieving full-scale pv capacity globalization by 2023, byd has systematically leveraged latecomer advantages by seizing technological, market, and institutional windows of opportunity amid global shifts. strategic initiatives have significantly expedited byd’s evolution from a component supplier to a globally recognized leader in the new energy vehicle (nev) ecosystem. case analysis and key findings byd’s "product globalization" strategy globalization of byd’s battery and electronics business in 1994, the founder of byd, wang chuanfu identified a critical event through environmental scanning: japan’s discontinuation of nickel-cadmium battery production. recognizing this as an unprecedented window of demand opportunity for chinese battery manufacturers, he mobilized r&d efforts to master nickel-cadmium battery technology, laying the foundation for byd’s battery and electronics business. by 1997, amidst the trend of plummeting global battery prices triggered by the southeast asian financial crisis, byd ingeniously implemented a "technology-for-market strategy", capturing 40% of the global nickel-cadmium battery market within three years and achieving annual sales exceeding 100 million cny. drawing on insights from environmental scanning, including event-trend correlations and experiences gained from success in the chinese market, byd expanded globally by establishing subsidiaries in the netherlands (1998) and the united states (1999), and began exporting mobile phone batteries and electronic components. table 2 outlines the timeline of byd’s battery and electronics product globalization. global sustainability research global scientific research 119 table 2: battery and electronics product globalization of byd time period typical supporting data core

angeles (1999), specializing in mobile phone battery sales. globalization of byd’s commercial vehicles in 2010, byd’s commercial vehicle division utilized its “7+4” full market strategy framework, giving priority to new energy buses and coaches, thereby widely implementing electric vehicle (ev) technologies in road transportation. in november of that year, the company introduced the innovative “urban public transportation electrification” solution, with the objective of reducing energy consumption and mitigating urban pollution resulting from traditional public transit systems. as of december 2024, byd’s new energy commercial vehicles—represented by its electric buses—have penetrated six continents, more than 100 countries and regions, and over 400 cities. this expansive global presence demonstrates how "environmental scanning + windows of opportunity" have empowered byd to monitor emerging trends through environmental surveillance and assess the impact of situational shifts on strategic decision-making. table 3 outlines key milestones in byd’s commercial vehicle globalization (partial). globalization of byd’s passenger vehicles amid the centenary global transformation and the rapid disruption of the automotive industry in 2021, spurred by china's dual-carbon policy objectives, byd successfully unleashed its accumulated strategic momentum across four core sectors: automotive, rail transit, new energy, and electronics. the passenger vehicle division embarked on a golden age marked by technological innovation, product upgrades, and market expansion. capitalizing on norway’s institutional and the windows of market opportunity—including world-leading nev adoption rates, abundant hydro-power resources, tax incentives, and road tax exemptions—byd forged a strategic alliance with rsa automotive dealer group. in may 2020, it entered the norwegian market with the tang ev as its flagship model. subsequently, in may 2021, byd formally launched its "passenger vehicle globalization strategy", accelerating nev deployment across global markets. table 4 outlines key milestones in byd’s passenger vehicle globalization milestones (partial). global

for ev/hybrid vehicle and component production; phase 1 produces chazor and song plus; targets 300,000 annual capacity. hungary initiated nev production hub in szeged city, hungary—byd’s first eu-based manufacturing facility. 2024 indonesia broke ground on $1.3 billion plant with 150,000-unit annual capacity. brazil began construction of mega-production complex (3 plants) in camaçari, bahia state, targeting 150,000 pvs annually. globalization of byd’s commercial vehicle production capacity the globalization of byd’s commercial vehicle production capacity—driven by demand orientation, cost efficiency, favorable policy incentives, and effective risk mitigation—emerged as an inevitable outcome of its comprehensive environmental scanning to exploit multidimensional opportunity windows. in may 2013, marked by the groundbreaking of byd’s electric vehicle factory in lancaster, california, marking the entry of this initiative into a strategic upgrade phase. byd’s selection of target countries for production capacity deployment hinges on three criteria. industrial infrastructure: host countries must possess automotive manufacturing foundations, including skilled labor, global sustainability research global scientific research 123 complete supply chains, and mature industrial capabilities. byd often leverages idle production capacity through third-party acquisitions to reduce costs—exemplified by its factories in thailand and brazil. policy and geopolitical alignment: target markets should demonstrate clear governmental support for evs, political stability, and china-friendly diplomatic relations. regions prioritized include southeast asian countries, central and eastern european nations, and latin american markets like mexico and brazil. emerging market advantage: developing countries lack dominant domestic car brands, which provides an opportunity for byd to rapidly capture market share through localized production. table 6: key behavioral evidence

marking a new chapter in its global expansion. byd’s selection of thailand was driven by the country's solid automotive industrial base and manufacturing prowess, along with a keen eye for institutional and market opportunities in thailand’s nev sector. with policy incentives like the development of charging infrastructure, smart grid construction, and tax reductions for nevs, thailand's nev market has expanded rapidly, exerting considerable market pull. geographically, thailand’s strategic positioning—with a long coastline, proximity to china (north) and asean nations (south), and access to over 20 international ports—provides unparalleled export advantages. notably, thailand’s low-trade-barrier agreements with japan and australia position it as a potential nev hub in southeast asia, facilitating byd’s strategic advancement. in december 2023, byd announced plans to build an nev pv production base in szeged, hungary, becoming the first chinese automaker to set up a pv manufacturing plant in the eu. this move underscores byd’s commitment to the european market and its acute awareness of global nev opportunity windows. as an eu member, hungary boasts convenient transportation networks, a robust industrial base, and a favorable business environment, serving as a strategic base for byd to further penetrate the european marketing. enhancement of byd’s dynamic capabilities and transformation of core globalization advantages: byd’s strategic transition from 'product globalization' to 'capacity globalization' fundamentally reflects a dynamic adaptation to global industrial restructuring trends. its absorptive capacity enables rapid assimilation of global advanced technologies and management practices; its adaptive capacity allows agile strategic adjustments to navigate complex markets; and its innovative capacity drives breakthroughs in products, technologies, and services. byd’s acute sensitivity to technological trends, market dynamics, and institutional shifts underpins its global competitive edge. table 6 outlines key behavioral evidence of byd’s dynamic capability enhancement and core advantage transformation. global sustainability research global scientific research 126 conclusion this study employs an exploratory single-case methodology to uncover critical determinants of successful corporate globalization. our findings demonstrate that acute market insights enable firms to identify windows of opportunity and respond to global demands, while enhanced dynamic capabilities facilitate opportunity conversion and core advantage transformation, ensuring effective implementation of globalization strategies. the primary conclusions are as follows: first, environmental scanning serves as an indispensable precursor to strategic decision-making in globalization. by integrating qualitative analysis, this study highlights how environmental scanning drives opportunity window identification and strategic alignment. through systematic scanning, firms gain comprehensive insights into international market dynamics, competitive landscapes, and regulatory shifts, enabling them to seize favorable conditions, mitigate risks, and substantiate overseas expansion decisions. second, windows of opportunity discovery act as the driving force for strategic choices. this research extends the application of opportunity window theory to corporate globalization strategy formulation. successful internationalization demands acute opportunity sensitivity—identifying latent market potentials through environmental scanning. such identification not only shapes the timing and target markets of globalization but also determines market positioning strategies and the strategic fit between dynamic capabilities and organizational decisions. third, continuous optimization of dynamic capabilities is imperative for adapting to global market volatility. firms must perpetually refine their competitive edge through product innovation, technological breakthroughs, and process reengineering, thereby achieving creative transformation of opportunity windows into sustainable advantages. the findings of this study offer practical guidance for chinese new energy vehicle (nev) enterprises to advance internationalization and achieve sustainable development. initially, enterprises ought to augment their investment in environmental scanning and establish formalized systems to meticulously monitor and dissect external factors, such as international market trends, competitive terrains, and regulatory changes, thereby furnishin comprehensive and precise insights for their global expansion strategies. second, enterprises must develop a keen market foresight by building robust information collection and analysis systems to enhance the accuracy and timeliness of opportunity window identification. third, firms need to continuously adapt and enhance their dynamic capabilities in response to global market evolution and internal growth imperatives. fourth, strategic globalization decisions must rigorously evaluate the alignment between identified opportunity windows and dynamic capabilities. through scientific and rational strategic planning, firms can seize favorable conditions, mitigate risks, and achieve stable overseas growth. first, enhance the policy support system. governments should formulate specialized policies to support the international expansion of the new energy vehicle (nev) industry, encompassing financial subsidies, tax incentives, and financial support. for instance, providing capital subsidies for nev enterprises establishing overseas production facilities could reduce internationalization costs and risks. strengthen the coordination and integration of industrial policies, trade policies, and diplomatic strategies to create synergistic policy effects. diplomatic channels should be leveraged to foster favorable international conditions, including enhanced intergovernmental collaboration with key target markets and the negotiation of bilateral/multilateral agreements, thereby securing institutional safeguards for overseas investments and market penetration. second, strengthen public services. relevant government departments should establish an nev industry internationalization information service platform to provide enterprises with overseas market intelligence, regulatory frameworks, and technical standardization requirements, enabling timely responses to market dynamics. global sustainability research global scientific research 127 implement talent development and recruitment programs to cultivate professionals in nev-related fields, while incentivizing overseas high-skilled experts to contribute to domestic innovation ecosystems. this dual approach ensures human capital reinforcement for global expansion initiatives. third, promote industrial collaboration. governments should facilitate synergistic cooperation across the nev industrial chain to harness cluster advantages. encourage component suppliers to elevate product quality and technological sophistication, thereby bolstering the competitiveness of vehicle manufacturers in global markets. foster industry-university-research partnerships to advance r&d in critical generic technologies (e.g., solid-state batteries, intelligent driving systems), enhance indigenous innovation capabilities, and establish a technological foundation for international market penetration. this study has the following research limitations and shortcomings: first, this paper relies solely on third-party public data collected from corporate websites, databases, and related platforms for analysis. the research content may not be comprehensive, and there may be discrepancies in data analysis compared to the actual situation of enterprises. second, this study adopts a single-case analysis approach, and the generalizability of the analytical conclusions may be inferior to that of multi-case comparative analyses. given the limitations of single-case analysis in generalizability, future studies should select multiple representative new energy vehicle (nev) enterprises as research subjects for comparative multi-case analysis. by systematically contrasting similarities and differences in internationalization strategies, opportunity window utilization, and dynamic capability deployment across enterprises, researchers can more profoundly reveal universal patterns and critical determinants underlying the globalization of the nev industry, thereby enhancing the generalizability of research findings. as for research methodology. future investigations could further integrate quantitative methodologies such as statistical analysis and econometric modeling. large-scale quantitative analysis of corporate data would enable validation of conclusions derived from case studies, thereby providing stronger empirical support for theoretical frameworks. simultaneously, the application of quantitative models could predict developmental trajectories and potential influencing factors in nev industry globalization, offering enterprises and policymakers a more forward-looking decision-making basis. declaration this is to declare that this manuscript is an original work and has not been submitted for publication elsewhere. acknowledgment: n/a funding:

accepted: 14 december, 2024, published: 20 december, 2024 abstract this paper aims to analyse the effects of public as well as private investments on food security in cameroon. the study, used data from 1988 to 2020 and generalized least squares method for estimation. the results revealed that (i) public investment reduce effect on food security while (ii) private investment has a positive effect on food security. therefore, the study suggests to cameroonian government to direct public policies towards investments in agricultural sector in order to boost food production, food availability and food accessibility in the country. keywords: investments; food security; public sector; private sector; generalized least squares method introduction an increase in the rate of food insecurity in the world is still a hot topic. the rate of food insecurity in the world has evolved over time. as of 2019, nearly 750 million people, or one in ten people worldwide, have experienced food insecurity (food and agriculture organization (fao), 2020). according to the report entitled ‘the state of food security and nutrition in the world 2020’, almost 690 million people, or 8.9% of the world’s population suffer from hunger. while the fight against hunger is stagnating, the covid-19 pandemic is intensifying global vulnerabilities and food shortages. in addition, the world’s population has increased thanks to a rise in the birth rate and improvements in the quality of human health care. in fact, the increase in population growth rate is a factor that boost demand for food on global level. however, despite a favourable outlook for global food supply, food prices increase and high transportation costs increase the cost of imported food. therefore, many countries experienced inflation in retail food price. labour shortages and the rise in the price of fertilisers and agricultural inputs are also other cause of increase in food prices. in the united nations development programme’s human development report (undp, 2019), cameroon’s human development index (hdi) was 0.563, placing the county in the 153rd out of 189 poorest countries. this hdi value places cameroon in the ‘medium human global sustainability research global scientific research 86 development’ category. let notice that the socio-political crises, has deteriorated food insecurity in cameroon from 12.8 % in 2019 to 20.5% in 2020. the distribution of food insecurity among regions in cameroon are as follows: 40% in the north-west, 30.7% in the west, 22.1% in adamaoua, 24.8% in the far north (ministry of agriculture and rural development, 2020, world food program (wfp), 2020, and fao, 2020). tough the country has enormous potential for sufficient food availability, it faces a number of humanitarian, security and health crises that compromise food security (fao, 2021). climate change, limited access to food, and poverty linked to economic shocks and inequality are factors of food insecurity. in addition, mainly terrorism (boko haram in far north), socio-political crisis in north-west and south -west regions, the increase of migrants from central africa country in the east region are other causes of food insecurity. food security in cameroon is also affect by speculation. in fact, the country is identified as the main producer of agricultural crop products in central africa, meanwhile, daka, wang and hu (2021) identified cameroon as the breadbasket of central africa. thus, producer and retailers choose to sale their products to neighbouring countries (gabon, equatorial guinea, chad, central african republic) where market price is higher than the one applies on local market, leading to shortage in local markets. yet, the agricultural sector in cameroon remains underdeveloped due to the inadequacies of investment in agricultural sector. the part of cameroonian government budget allocate to agricultural sector is 4.5% of the government total of annual expenditure (national statistics, 2019). despite the engagement took in the maputo declaration in july 2003, where heads of african states agreed to allocate at least 10% of their budgets to develop agricultural sector in order to achieve agricultural growth at 6% (new partnership for africa’s development, mbaku, 2004). the country has not respected this engagement, for instance in 2021 just 1.86% of budget was allocate to agricultural sector (national statistics, 2021). with respect to current debate on the link between investment and food security in the world, the authors propose to participate to this debate trough this paper entitle: the effect of public and private investment on food security in cameroon. the study aims to assess the effects of both public and private investment on food security in cameroon through this main question: what is the link between investment and food security? to answer this question, two assumptions was made: firstly, the effect of public investment on food security and secondly, the effect of private investment on food security. to answer this question, we will use two assumptions: firstly, the effect of public investment on food security and secondly, the effect of private investment on food security. this paper is structure as follows: section two presents literature review on the relationship that actually exist between different types of investments and food security, methodology of the study is in section three, while the main results and their interpretations are presented in section four, finally the study is concludes with main recommendations towards the publics authorities in cameroon. literature review the agricultural policy of cameroon was defined in the five -year plans from 1975 to 1986 and aims to increase agricultural production in order to achieve food security. however, the increase in agricultural productivity is linked to the increase of investment in agricultural sector. for instance, the joint statement on global food security issued by the g8 meeting held in aquila (italy) in june 2009 recognises that, the combination of chronic under-investment in agriculture and economic instability are two mains causes of persistent food insecurity. thus, both public and private investment in the agricultural sector can play an important role in ensuring food security for the population. investment in agriculture appear as a most important and effective strategy for reducing food insecurity in rural areas, where the majority of the world’s poorest people live (world bank, 2007 and fao, 2012). since the investment needed to develop an agricultural value chain plays an important global sustainability research global scientific research 87 role in reducing food security, consequently investment in agricultural sector have had a positive impact in many countries. public investment and food security review of global literature on the link between public investment and food security agricultural value chains have often increased the availability and quality of food, if they focus on a diversity of crops consumed locally, and have also contributed to increase food production (bishwajit and yaya (2024), cleaver, 2013; rutherford et al., 2016; kaplan et al., 2016). in this perspective, public spending can be directed towards subsidising agricultural projects (daka, wang and hu, 2021). the subsiding of agricultural input is generally intended to increase productivity through better access to fertilisers. thereby contributing to a rise in producers’ income (lower production costs) and a fall in consumer prices (increased supply) (kazukauskas, et al., 2014; jayne et al., 2018; solaymani et al., 2019). in this vein, kanter et al, (2015) have shown that input subsidy policies are likely to lead an increase in agricultural production, which later provides additional income to farmers, enabling them to purchase foodstuffs that can improve the nutritional status of the household. therefore, the financing of agricultural activities is also crucial to ensuring food security. the financing of agriculture makes a significant contribution to agricultural production. while strengthening and diversifying agricultural financing promotes the development of food markets (ibrahima thiam and malick, 2020). meanwhile, the financing of agricultural sector in cameroon shows that there is a positive relationship over time between agricultural financing and food security (biligil, 2017). public investment in agriculture is necessary to reduce food insecurity (world food program, 2020 and world bank, 2017). as food prices likely to rise, investment in the agricultural sector has become more essential for guaranteeing food security around the world. as a result, investment in research and development, physical infrastructure, and communications technologies contribute to improve the availability and access to food (kristova et al.,2017; heisey and fuglie, 2018). thus, spending on research and development as well as on support services of agriculture contribute to food security by promoting food systems that guarantee basic diets (shankar, chunk and frank, 2017). it has also noted that investment in education has a positive effect on the population’s food security. it promotes agricultural productivity, the higher the level of education of the farming population, the higher will be the agricultural productivity. in this vein, mengoub (2018) in her paper entitled ‘agricultural investment in africa: a low level… many opportunities’, shows that investment in education is seen as an effective means of increasing agricultural productivity gains. this improvement in agricultural productivity increases the availability of foodstuffs. despite many policies adopted by various government across the world, the agricultural sector still faces limited investment that is view as main factor of food insecurity. meanwhile, food security has become main objective of agricultural policy for every country. thus, investment is recognized as a key variable mainly in rural areas where it has been identified as an essential element of the fight against poverty and food insecurity (, world bank, 2007; barret et al., 2010; de janvry and sadoulet, 2010). in this line, alston et al., (2009) show that agricultural investment from farmers or from the public sector to increase productivity at farm level can also improve the availability of food on the market and exert downward pressure on prices, making food affordable to consumers. public investment in the agricultural sector should therefore have a positive impact on food security and poverty. increase in public investment in agricultural sector expected to have a positive impact on food security, not only in rural areas but also in urban areas, as the fall in prices resulting from growth in global sustainability research global scientific research 88 production will satisfy both rural and urban populations (burchi, scarlato and d’agostino, 2018; timmer, 2000; fao,2012). review of synthetic literature on the link between public investment and food security according to douillet and girard (2013), agricultural production depends not only on the soil and climate, but also on the technologies available, farming practices and public policies that directly or indirectly affect farmer’s activities, through their general or specific economic orientation. these authors highlight the importance of state intervention in the agricultural sector through public investment and the quality of the institutions that promote agricultural development. though agriculture remains a main pillar of development in many developing countries, over time its contribution to gross domestic product (gdp) has declined in many parts of the world, partly due to low investment and the neglect of this key sector in favour of manufacturing industries (forum for agricultural research in africa (fara), 2006). investment in agricultural sector is divided into economic and social infrastructure. public investment in agricultural research, road, electrification and education generates high returns in terms of agricultural growth and poverty reduction, that are highly complementary to private investment. state funding of agricultural activities plays an important role in food security. in fact, agricultural financing makes significant contribution to production, strengthening and diversifying agricultural activities, thus promotes the development of food markets the funding of agricultural projects or granting subsidies to farmers increase the availability of foodstuffs trough the increasing of agricultural productivity (ibrahima, thiam et malick, 2020). in this same vein, biligil (2017) analysed the impact of public funding of the agricultural sector on the growth of agricultural products in cameroon. the results show a positive relationship over time with public spending allocated to the agricultural sector. the growth of agricultural production has contributed to the reduction of food insecurity among local population. thus, public investment in agricultural sector has a positive impact on food security. public investment in education mainly in vocational training in agriculture, improve farmers skills who are more effective and efficient in practising modern technics of farming (mengoub,2018). public spending to support food prices mainly towards price support and aid for farmers has a positive effect on food security. for instance, kaya and erden (2008) in their paper concluded that development aid devoted to agricultural sector and growth have a positive relationship. therefore, the level of food prices is a key determinant of food security. in fact, when prices are low, people are able to buy and vary their diet more. however, timmer (2010) argued that, the volatility of food prices is evidence of the existence of food crises due to dynamic public policies to support the production or consumption of food and non-agricultural products. investment in agricultural sector can also reduce the vulnerability of food supply to shocks, thereby improving the stability of consumption. on the supply side, a period of high prices leads the government to encourage research and investment in order to increase agricultural production. public and private sectors can invest in the construction of food storage and other infrastructure to ensure supply. however, the period of low prices reduces the interests of governments, resulting in a decline in public support. private investment and food security review of global literature on the link between private investment and food security the world bank (2007) recommends to governments to ease the pressure on national food security by attracting foreign direct investment (fdi) in order to solve chronic problems of low investment in agricultural sector. global sustainability research global scientific research 89 however, a negative effect of foreign direct investment in major developing countries were noticed. fdi has led to an increase in the rate of food insecurity, due to foreign investors seeking to maximise their interests by exploiting the resources of developing countries (bjornlund, bjornlund and rooyen, 2022). for instance, world bank (2004) noted earlier that fdi flows into agriculture tend to be highly volatile. agriculture is land-based activities, and land is owned by major local elites who concentrated benefits from fdi. in this same line, alfaro (2003) and aykut and sayet (2007) have shown in cross-country empirical analysis that fdi in primary agriculture hurt economic growth in developing countries. fdi in agricultural sector has led to environmental problems. in this line, clapp (2003) in his studies noted that governments in developing countries have followed foreign agricultural policies that favour the use of chemical-dependent technologies due to the involvement of multinational firms in agricultural projects. multinational firms, use high-intensity pesticides and fertilisers that replaced natural crop rotation and organic fertilisers (altieri, 2000 and jorgenson, 2007). in some cases, foreign investors in developing countries use substances that are banned in developed countries for environmental norms (magdof et al.,2000 and shiva and bedi, 2002). the pollution of water sources poisoned farmland and later force the migration or the abandonment of subsistence farms by local producers. in addition, the use of chemical fertilisers can be the cause of certain diseases in developing countries. therefore, private investment can act as a brake on the development of poor countries (mihalache and li, 2011). studies of the effects of fdi on food security in developing countries show that energy consumption was negatively related to fdi in agricultural sector in both short and long term (djogoto, 2022). in fact, some social conflict arises mainly the large-scale of land acquisitions by foreign firms that lack transparency in land transfers and the absence of consultation with local stakeholders. in addition, land transfers involve the displacement of local small holders and the loss of grazing land for nomadic pastoralists that later lead to food insecurity in local population due to the export of crops produce by foreign firms. moreover, there are concerns on the highly mechanised production methods from foreign firms, that limited job creation and increase the rate unemployment of local population (hallam, 2011). despite, the negative effects stresses in the preview paragraph, fdi in agricultural sector have positive effects on food security. for instance, subsidising highproductivity agriculture increases the quantity of food available. in this line, frimpong and oteng (2008) have noted the diverse importance of fdi for host countries including: the influx of foreign capital increases the supply of funds for investments, thereby promoting capital formation, and the direct contribution to the food security of local population. multinational firms have also helped to set up restaurants and large supermarket where consumers can find wide variety of foodstuff at competitive prices. as a result, the population is foodsecure. in this same vein, aloui and maktouf (2024) found out in the studying the impact of fdi and political stability of food security in ssa found out that fdi positively impact food security in the region. review of synthetic literature on the link between private investment and food security skoet, kostas and deuss (2004), argued that growth, poverty reduction and food security, particularly in the poorest countries, depend on investment and rural economic activities. the low level of investment in agricultural sector in major developing countries is reflected in low productivity and stagnant production. despite the priority given to agriculture, many developed countries are facing limited financial capacities to invest in agriculture in developing countries. while, developing countries have limited access to bank loans from commercial bank and microfinance, meanwhile these countries turn to fdi. fdi in agricultural sector is an historical phenomenon since colonial period where large firms were established to import technical equipment and export raw materials and crops product to support european industries. thus, private investment has important effect on food security, including the exploiting of fertile and irrigable land took from local global sustainability research global scientific research 90 population. in the same line, corporations (2009) stresses that the technological contributions of multinational firms have been limited due to difficult transfer and diffusion of technologies to small farmers. in fact, the advantages of technologies and productions from fdi is near zero, if the crops produce are entirely export to investor countries. in addition, multinational firms paid very low wages to local population unenabled them to meet their food requirements and encouraged the move of rural population to the cities, thereby the reduction of agricultural workforce and the increase in food prices in the cities (reardon et al., 2003). a model will be an important tool for analysing the impact of national investment on food security in cameroon. empirical review of models on the effects of investment on food security major analysis of the effect of investment on food security use different models. for instance, zidouemba and gerard (2015) in their paper entitle: ‘investment and food security in burkina faso’ used computable general equilibrium (cge) model to analyse the effect of public investment in agriculture in burkina faso. while, ibrahima thiam and malick (2020) in their paper entitle ‘empirical links between agricultural financing and food security in senegal’ used multiple regression model inspired by kpodar (2006) for analysis. while aloui and maktouf (2024) used general moment method to the impact of fdi and political stability of food security in ssa. among various models, this study uses multiple linear regression model and the error correction model for analysis. expliquez pourquoi? the above literature stresses the effect of both public and private investment on food security. all authors agreed on the fact that public and private investments have a certain effect on food security, however the effect can be negative or positive. some studies highlight the factors that cause food insecurity, some factors are identify on individual (social) level while other are on national and/or regional level (political, economic, cultural). literature also, stress variables that affect food security, including: climate change, natural resources, land, financing, education, health, political conflicts, government policies, physical infrastructures, ect. in addition, major studies on food security are done on regional level or in cross countries studies, few studies are done on a single country due to a difficulty to constitute a strong database over a long period of time. however, this study overcome this challenge by focusing on cameroon context and shed light on how both public and private investments and various variables could significantly affect food security in the country. methodology multiple regression model based on the assumption that financing of agricultural sector contributes significantly to food security. ibrahim, thiam, and malick (2020), used the multiple regression model to analyse the linkages between agricultural financing and agricultural production in senegal. these authors model is based on the models of kpodar (2006) and jeanneney and kpodar (2011). both models present the impact of financial development on poverty. the theoretical model can write as follow: 𝑙𝑜𝑔(𝑃𝑆𝐴𝑡) = 𝑎0 + 𝑎1 log(𝐹𝐼𝐴𝑡) + 𝑎2 log(𝑉𝐴𝐴𝑡) + 𝐴𝑋 (1) where, psa is the prevalence of undernutrition, fia is agricultural financing consisting of bank credit, vaa is agricultural value added and x is a set of control variable (with elasticity a), food availability in kilocalories global sustainability research global scientific research 91 (disk), gross national income per capita (rnb_h) and outstanding loans from microfinance institutions (c_imf), t is the period index. the theoretical model can be rewrite as follow: log (𝑃𝑆𝐴𝑡 ) = 𝑎1 log(𝐹𝐼𝐴𝑡) + 𝑎2 log(va𝐴𝑡) + 𝑎3 log ( 𝑉𝐴𝑁𝐴𝑡) + 𝑎4 log(𝑃𝑂𝑃𝑡) + 𝑎5(𝐷𝐼𝑆𝐾)𝑡 + 𝑎6 log(𝑅𝑁𝐵_𝐻𝑡) + 𝑎7log (𝐶_𝐼𝑀𝐹𝑡) + 𝐶 + 𝐸𝑡. (2) the prevalence of undernutrition (psa) represents the level of food security in a country that is capable of capturing the population with insufficient access to adequate, regular and nutritional food for an active and healthy life. agricultural financing (fia): is made up of short-term financing ( 𝐹𝐶𝑇𝑡 ),medium-term financing(𝐹𝑀𝑇𝑡 ), and long-term financing(𝐹𝐿𝑇𝑡 ), so, 𝐹𝐼𝐴𝑡 = 𝐹𝐶𝑇𝑡+𝐹𝑀𝑇𝑡 +𝐹𝐿𝑇𝑡 .agricultural value added (vaa) is an indicator that informs the agricultural entrepreneur about his ability to pay labour and capital factors. non-agricultural value added (vana), it is part of the agricultural value chain. food availability in kilo calorie (disk): is the daily per capita food energy availability that corresponds to the available food for consumption during the reference period. gross national income per capita (rnb_h) is the sum of value added produced by all residents plus all tax revenues. population (pop) is the number of people or inhabitants to be fed during a given period. the outstanding credit of mfis (c_imf) is an indicator to measure the financing of mfis intended for the client. error correction model the model specification is based on the approach used by nupuko (2007), adapted from the models of ojo and oshikoya (1995), ghura and hadjimicheal (1996) and tenou (1999) on real gdp growth in african countries. the model considers the two channels of public expenditures’ effects on the growth of agricultural sector. the formulation links production and factors that may influence growth of agricultural sector. these are direct and indirect factors. the direct factors are labour, private capital, land and agricultural public expenditures. indirect factors are general public goods such as electricity and education. the general specification of model can be written as follow: 𝑃𝑟𝑜𝑑 = 𝑓(𝐷𝑃𝐴, 𝐿𝑎𝑏, 𝐿𝑎𝑛𝑑, 𝑃𝑟𝑖𝑣, 𝐸𝑙𝑒𝑐, 𝐸𝑑𝑢) (3) where, prod is agricultural production, dpa: public expenditure on agriculture, lab: labour, land: land, priv: private capital, elec: electricity, educ: education. the equation can be written as follow: △ 𝐼𝑛𝑃𝑟𝑜𝑑 = 𝑎1 △ 𝐷𝑃𝐴 + 𝑎2𝐿𝑎𝑏 + 𝑎3 △ 𝐼𝑛𝐿𝑎𝑛𝑑 + 𝑎4 △ 𝐼𝑛𝑃𝑟𝑖𝑣 + 𝑎5 △ 𝐼𝑛𝐸𝑑𝑢 + 𝑎6 △ 𝐼𝑛𝐸𝑙𝑒𝑐 + 𝑎7 △ 𝐼𝑛𝑃𝑟𝑜𝑑 + 𝑎8 △ 𝐷𝑃𝐴−1 + 𝑎9𝐿𝑎𝑏−1 + 𝑎10 △ 𝐼𝑛𝐿𝑎𝑛𝑑−1 + 𝑎11 △ 𝐼𝑛𝑃𝑟𝑖𝑣−1 + 𝑎12𝐼𝑛𝐸𝑑𝑢𝑐 + 𝑎13𝐼𝑛𝐸𝑙𝑒𝑐−1 (4) in this expression, △ is the derivative factor with respect to time. the coefficients 𝑎𝑖are the elasticities. the coefficients 𝑎1 𝑡𝑜 𝑎6 characterize short-term dynamic while the coefficients 𝑎8 to 𝑎13 allow the longterm equilibrium behaviour of the growth rate of agricultural production to be derived and the coefficient 𝑎7 is the error correction coefficient. global sustainability research global scientific research 92 model specification the model of this study is based on the models of kpodar (2006) and jeanneney and kpodar (2008). the originality of these models is a relationship between cobb-douglas function and agricultural production and its explanatory factors. in fact, this type of function was used by barro and salai-martin (2004) and guillaumont (2004). mundlak et al., (2002) also used this type of function for a determinant analysis of agricultural growth in indonesia, the philippines and thailand. the model of equation is in the following form: 𝑃𝐼𝐵𝑡 =𝑓(𝑋1𝑡 , 𝑋2𝑡, 𝑋3𝑡 , … . 𝑋𝑛𝑡). (5) the equation can be rewrite as follow: 𝑃𝐼𝐵𝑡 = 𝑋1𝑡 , 𝑋2𝑡 , 𝑋3𝑡, … 𝑋𝑛𝑡. (6) 𝑃𝐼𝐵𝑡 is the agricultural domestic product, is a function of agricultural production. 𝑋𝑛𝑡 represent the variables explaining the rate of food insecurity at a given time t. the equation in logarithmic form is as follows: 𝐿𝑜𝑔(𝑃𝐼𝐵𝑡) = 𝑎0 + 𝑎1𝑙𝑜𝑔𝑋1𝑡 + 𝑎2𝑙𝑜𝑔𝑋2𝑡 + ⋯ 𝑎𝑛𝑋𝑛𝑡 + 𝐸𝑡. (7) in the context of the effect of national investment on food security in cameroon, several variables explain food insecurity measured by agricultural gross domestic product. the main variables explaining agricultural production are (i) public and private investments. the variables of the model are: public investment (𝐼𝑝𝑎𝑡), private investment measured by foreign direct investment (ide), electricity (elec), rural population (𝑃𝑜𝑝𝑡) ,gross domestic product (𝑃𝑖𝑏𝑡), inflation (𝐼𝑛𝑓𝑡), agricultural land (𝑇𝑒𝑟). the model for the analysis is as follows: 𝐿𝑜𝑔(𝑇𝐼𝐴) = 𝑎0 + 𝑎1log(𝐼𝑝𝑎𝑡) + 𝑎2log(𝐼𝑑𝑒𝑡) +𝑎3𝑙𝑜𝑔𝐸𝑙𝑒𝑡 + 𝑎4 log 𝑃𝑜𝑝𝑡 + 𝑎5𝑙𝑜𝑔𝑃𝑖𝑏𝑡 + 𝑎6𝑙𝑜𝑔𝐼𝑛𝑓𝑡 + 𝑎7𝑙𝑜𝑔𝑇𝑒𝑟𝑡 + 𝐸𝑡 (8) where 𝑎0 is a model constant 𝑬𝒕 is the error term, 𝑎𝑖 represent the coefficients of the variables of the model. description of variables of the model seven variables were selected to explain the rate of food insecurity in cameroon. dependent or explained variables the rate of food insecurity at a time 𝒕 (𝑻𝑰𝑨𝒕): it represents a situation where all people have sustainable physical, social and economics access to sufficient and nutritional food that meets their need and dietary preference. in this study, the value added of agricultural production proxy by gross domestic product it used as dependent variable. global sustainability research global scientific research 93 independent or explanatory variables public investment expenditure (𝑰𝒑𝒂𝒕) expenditure by the state to promote a country’s socio-economic development. public investment in agriculture is used to acquire durable goods and services for uses as means of production. public investment is gross fixed capital formation (gfcf) by general government. the choice of this variable is justified by its effectiveness in increasing agricultural production. figure 1 represent public investment in agricultural sector in cameroon. source: authors’ own elaboration from stata 14.0 public investment in agricultural sector in cameroon is periodic and not stationary. there is a succession of growth and decline over time. from 1988 to 1992, public investment fell to the lowest level. from 1992, public investment will grow and vary moderately until the 2020s. private investment measured by foreign direct investment (ide), these are net investment inflows to acquire a lasting stake in a sector operating in an economy other than that of the investor. the choice of this variable is justified by the fact that fdi uses much of the agricultural land in developing countries for its activities. figure 2: private investment in agricultural sector source: authors’ own elaboration from stata 14.0 fdi has increase year to year from 1990 up to 2020 period. figure 1: public investment in agricultural sector in cameroon global sustainability research global scientific research 94 electricity (elec), is considered to be public infrastructure that helps to open up rural areas and improve conditions for farming. electricity encourages the development and the establishment of agri-food industries in rural areas. the figure 3 represents the rural population has access to electricity service. figure 3: electricity distribution source: authors’ own elaboration from stata 14.0 figure 4: agricultural population in cameroon source: authors’ own elaboration from stata 14.0 the curve representing agricultural population is increasing and linear over the period from 1990 to 2020. this growth in the agricultural population may be due to an increase in the birth rate in rural areas. this curve representing access to electricity in cameroon, from 1988 to 1991, the series is periodic and from 1991 public investment in electricity increases more and more. show us that cameroon is multiplying its efforts to offer a significant quantity of electricity to its population. from 2019 the curve declines sharply indicating a global sustainability research global scientific research 95 drop in public investment in the electricity sector in cameroon. rural population (𝑃𝑜𝑝𝑡) represents all the people living in rural areas who are part of farming households. it refers to people living in rural areas as defined by the national statistics institution. the interest of choosing this variable is to see the impact of the increase in the rural population on the rate of food security. the evolution of agricultural population in cameroon is represents in figure 4. agricultural gross domestic product (𝑃𝑖𝑏𝑡) is an indicator that quantifies the total value of annual wealth production by economic agents in a given territory, while the agricultural gross domestic product represents the aggregate of production value, it is annual wealth created by the agricultural sector in a given country. figure 5 present the evolution of the agricultural gross domestic product in cameroon. figure 5: agricultural population in cameroon source: authors’ own elaboration from stata 14.0 the curve of agricultural gross domestic product in cameroon decreasing over the period from 1988 to 2020. this decline can be explained from the decrease in marginal labour productivity of the agricultural sector. it may be also to the decline in public investment, draining of natural resources and the infertility of agricultural land. inflation (𝐼𝑛𝑓𝑡): is a loss of purchasing power of money, resulting in a general and sustained increase in the prices of goods and services. inflation as measured from the consumer price index reflects changes in the cost of a basket of goods and services purchased by the average consumer. the inflation was chosen as variable because the rise in prices influences consumption power. figure 6 presents the variation in the prices of consumer goods in cameroon. global sustainability research global scientific research 96 figure 6: inflation in cameroon source: authors’ own elaboration from stata 14.0 figure 6 shows that inflation is not stable. a consumer prices evolves from a minimum and negative value to reach a maximum value in 1992. from 1992, the curve decreases and the stabilise between 0 and 5 until 2020. agricultural land (𝑇𝑒𝑟), is a part of land that is arable and permanently cultivated or grazed. arable land includes land defines by the fao as land for temporary crops, temporary land for reaping or grazing, land where vegetable gardens are grown and temporary land set aside. figure 7 presents agricultural land in hectares in cameroon. figure 7: agricultural land in cameroon source: authors’ own elaboration from stata 14.0 figure 7 highlights that, the surface of agricultural land in cameroon has remained stable over time, though there was an exponential increase over a short period of one year before falling to in a minimum value by 2020. global sustainability research global scientific research 97 results and discussions descriptive statistics test table 1. descriptive statistics of the variables source: authors’ own elaboration from stata 14.0 overall comments that can be made from table 1 is that variables relating to gross domestic product (131907), public investment (2814199) and agricultural population (42943) have the largest standard deviations, this means a great variability or volatility of these variables. conversely, variables such as agricultural land (1, 3366) and access to electricity (1.4793) have a higher standard deviation, that means they are less variable or volatile. stationarity test for variables a time series is said to be stationary weak, if its statistical properties do not vary over time (expectations and variances). in this study, to test the stationarity of variables, the augmented dickey fuller test was used. this test allows to highlight the stationary or non-stationary character of a time series by determining a deterministic or stochastic trend (bourbonnais,2006). the dickey-fuller test allows to test the stationarity of a series with for hypothesis zero (the series is not stationary) against and alternative hypothesis (the series is stationary) at the error threshold of 5%. the decision rule (accept or reject null hypothesis) consists of comparing the absolute value of the augmented dickey-fuller statistic (adf) with the absolute value of mc kinnon’s (1973) critical value (cv) read. table 2. results of stationary test on the variables source: authors’ own

the variables of the model. it can be noticed that variables in the econometric model are not stationary at any level. these values are augmented dickey-fuller statistical values where i (0) represents the order of integration of the level test and i (1) the order of integration of the first difference test. thus, the variables, agricultural gross domestic product and agricultural population are integrated at level and are therefore stationary that means that the means, variances and covariances do not depend on time. the other variables: agricultural land, inflation, foreign direct investment, public investment and electricity are stationary in first difference. the variables have different integration orders, meanwhile they are integrated at different levels so the co-integration test will be performed to see the co-integration between these variables. johannsen co-integration test between variables the co-integration test is to examine how two or more non-stationary time series can be tested, to verify whether the combined value of these series is stationary. table 3 presents the results of johannsen co-integration test. results from table 3 shows that the trace statistical values are greater that the critical values at the 5% threshold. therefore, the null hypothesis of co-integration between variables is accepted. correlation test on series in the analysis of our series, it is necessary to see the correlation that exists between the variables of the model. table 4 presents the correlation test result. model validation tests jarque-bera test is used to check the normality of statistical distribution. normality exists when the jarquestatistical value is less than 5.99 or when its probability is greater than the 5% threshold. table 5 present the results of jarque-bera test. the jarque-bera test of normality gives a probability of 0.00 less than 5%, it can be concluded that values are not well distributed or do not follow the normal law (normal distribution). breush-godfrey test, allows to check whether the errors are auto-correlated or not. there is autocorrelation if statistical value calculated in absolute value is less than the unit. table 6 present the result of breush-godfrey test. table 3. results of johannsen co-integration test. source: authors’ own elaboration from stata 14.0 rank trace statistics p-value at

figure 8 present the result of cusum test. figure 8: cusum test source: authors’ own elaboration from stata 14.0 figure 8 shows that the curve associated with this test does not cut through the corridor (in red). the conclusion is that the model is therefore stable at 5% threshold. final results, interpretations and discussions public investment and food security the summary of the results of the estimate model is gives in table 8. the overall comments that can be made from table 8 are as follows: the estimate model gives a probability associated with fisher statistic of 0.0077. as this gives a lower probability than the 5% significance level, we can conclude that the model is globally significant. a coefficient of determination of the model is equal to 0.39 (r2 = 0.39) this shows that 39% of the variability of gross domestic product is explained by agricultural population and public investment. the results of individual significance tests by the probabilities associated with the student statistic show that the variable public investment and the agricultural population are significant at 10% significance level. global sustainability research global scientific research 101

public investment (ipa): appears with a negative sign, this means it is negatively correlated with the agricultural gross domestic product. it is also significant at 10% level, meaning that an increase of one unit in public investment results in a 0.9226 reduction in the value of agricultural domestic product. the reduction in agricultural value added (in gross domestic product), following an increase in public investment can be explained by the fact that not all investment is favourable for the development of the agricultural sector. increase in public spending on long-term investments such as economic and social infrastructure do not have a direct impact on agricultural production. the increase in government spending may be due to tax increases that have negative effects on farmers’ incomes. these results are different from the results of biligil (2017) when studying public spending and agricultural growth in cameroon, find out that an increase in public spending in the agricultural sector is followed by an increase in agricultural production.rural population (pop): the coefficient associated with the agricultural population variable has a positive sign. this variable is significant at 10% level. however, an increase of one unit in the rural agricultural population will lead to an increase of 1.187 in agricultural gross domestic product. an increase in the highly active population is a labour force. the quality of care and training of farmers determines the level of agricultural production. the more educated and healthier the agricultural population, the more productive it will be and consequently an increase in agricultural value added (mengoub,2018).inflation on consumption goods, the coefficient associated with inflation variable is positive but not significant in the model. foreign direct investment and food security the summary of the results of the estimation 2 is gives in table 9 table 9. results of the estimation 2 variables

2 from table 9 show that a probability associated with the fisher statistic is 0.0001, this probability is below the 1% significance level, therefore the model is globally significant. the variables foreign direct investment, agricultural land and inflation are globally significant at 1% significance level. in this model the coefficient of determination r2 shows 64% of the variability of gross domestic product is explained by foreign direct investment and agricultural land. agricultural land: the coefficient associated with the agricultural land variable has a negative sign, but significant at 1% significance level. therefore, an increase of one unit of agricultural land will lead to a decrease of 0.20 in agricultural value added (agricultural domestic product). this reduction in added value may be due to poor use of the land by farmers. many factors can explain this situation: the renting of arable and irrigable by industrial firms, the lack of financial means to practice extensive agriculture on a large area of agricultural land, the scarcity of arable land (farmers are not able to access arable land) therefore reduce agricultural value (corporations, 2009). foreign direct investment (fdi): is positively correlated with agricultural gross domestic product at the 1% significance level. the entry of one unit of fdi in cameroon will increase gross domestic product by 0.20. this result is in line with ibrahim, thiam, and malick (2020), who found out that fdi positively impact agricultural sector. the increase in agricultural value added is the outcome of the benefits of fdi inflows into agricultural sector through various channels including: technology transfer mainly new techniques in agricultural practices that enable local population to practice extensive and highly profitable agriculture, building infrastructure that directly or indirectly supports the development of agricultural activities and financing (zidouemba and gerard, 2015). in fact, foreign investors are intervening in agricultural sector in cameroon through the financing of different agricultural projects from various ministries. inflation: this variable is negatively correlated with agricultural value added but is not significant in the model. conclusion this paper aims to access the effects of both public and private investment on food security in cameroon. literature review highlights that food security for the population is an objective pursued by several institutions and government. the study used multiple regression model and error correction model to stress the relationship between both public and private investment on food security. the different estimations show the significant effect of both investment on food security. public investment appears to have a negative effect on food security while private investment proxy by foreign direct investment (fdi) have a positive effect on food security. the argument for these controversial results, is that an increase in government spending may be due to tax increases that have negative effects on farmers’ incomes and the fact that not all government investment is favourable to agricultural sector. the positive effect of foreign direct investment is mainly explained by the involvement of foreign investors mainly non-governmental organisations (ngos) in the financing of various agricultural project from different ministries in cameroon. thus, to ensure food security in cameroon, particular attention needs to be paid to rural areas, where the majority of poor live. the government therefore can invest in the construction of social and economic infrastructures mainly road and communications infrastructures in order to enable farmers to obtain accurate information on supply and demand and easily access to local and national markets in order to deliver their agricultural products. government of cameroon can ensure vocational training global sustainability research global scientific research 103 of cameroonian youth that represent the major of active population through the creation of training schools for agricultural practices and natural resources transformation that are important factors for food security of the cameroonian population. finally, cameroonian government can ensure that policies, laws and regulations that govern agricultural investment mainly land

fermentation processes; bioproduct industries https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 78 introduction glucose, a fundamental biomolecule and major source of energy in living organisms, is essential in a variety of biological processes and industrial uses. because of the growing demand for clean and renewable energy sources, its production and consumption have received substantial attention. glucose production is critical not just for the food and biofuel industries (zahonyi et al., 2022), but also for the synthesis of a wide range of bioproducts. over the years, significant work has been expended on understanding and optimizing the processes involved in glucose synthesis. previous studies have explored enzymatic hydrolysis of polysaccharides, acid hydrolysis of biomass, and fermentation of sugars as the main pathways for glucose synthesis (ciolkosz et al., 2022). various feedstock sources, including agricultural residues, forest biomass, algal biomass, and food waste, have been investigated for their potential in glucose production (chen et al., 2022; premjet et al., 2022). however, despite the progress made in this field, several challenges persist. the kinetics of glucose production, influenced by microorganism strains and environmental factors, remain complex and require further exploration. optimization of the glucose production process to achieve maximum yield and economic efficiency continues to be a pressing concern (pereira et al., 2021). additionally, the sustainable and eco-friendly aspects of glucose production demand meticulous evaluation through life cycle assessments and techno-economic analyses. the primary aim of this comprehensive study is to provide an in-depth exploration of glucose production, considering various biochemical processes, feedstock sources, and optimization strategies. by comparing different enzymatic, acid hydrolysis, and fermentation techniques, this study aims to identify the most efficient and sustainable pathways for glucose synthesis. furthermore, by examining locally sourced materials and agricultural residues as potential feedstock, the study intends to offer practical insights into utilizing renewable resources for glucose production. objectives of the study are to investigate the enzymatic hydrolysis of polysaccharides and its kinetics for efficient glucose production, examine the acid hydrolysis of biomass to explore alternative pathways for glucose synthesis, assess the potential of fermentation processes for converting sugars into glucose, compare and evaluate various feedstock sources, including agricultural residues, forest biomass, algal biomass, and food waste, for their suitability in glucose production, optimize glucose production processes using statistical design of experiments and response surface methodology, and analyze the technoeconomic aspects and conduct life cycle assessments for a comprehensive evaluation of the sustainability of glucose production methods. this study holds paramount significance for academia, industries, and policymakers alike. by providing a comprehensive overview of glucose production, the research seeks to contribute to the scientific understanding of fundamental biochemical pathways. the optimization strategies and insights into feedstock utilization can pave the way for more sustainable and economically viable glucose production processes. furthermore, this study's focus on environmentally friendly and renewable carbohydrates aligns with global efforts to transition towards green and eco-conscious solutions. ultimately, the outcomes of this research aim to drive innovation and advancements in glucose production, fostering a sustainable future for various industries and human well-being. literature review background on glucose production glucose, a simple sugar, holds significant importance as a versatile platform chemical with wide-ranging applications in various industries, including food, pharmaceuticals, biofuels, and bioplastics (johns, 2021). to meet the growing demand for glucose sustainably, the utilization of renewable feedstocks has become a major https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 79 focus of research. among potential feedstocks, lignocellulosic biomass such as sawdust, rice husk, and sugarcane bagasse have drawn attention due to their abundance and potential for valorization. the enzymatic hydrolysis of these feedstocks can liberate glucose, which can then be further optimized using statistical techniques like response surface methodology (rsm) and the michaelis-menten model for kinetic analysis (ude et al., 2020). aspergillus niger, a filamentous fungus, is a widely studied microorganism with notable enzymatic capabilities, including cellulase and hemicellulase production. its potential for converting lignocellulosic biomass into glucose makes it an attractive candidate for glucose production. by harnessing the enzymatic prowess of aspergillus niger, the hydrolysis of cellulose and hemicellulose in sawdust, rice husk, and sugarcane bagasse can be efficiently achieved, leading to enhanced glucose yields. rsm is a powerful statistical tool that allows for the optimization of multiple variables simultaneously. in the context of glucose production from different feedstocks, rsm can explore the effects of parameters such as enzyme concentration, temperature, ph, and reaction time on glucose yield (jones et al., 2018). the technique provides insights into the interactions between variables and helps identify the optimal process conditions that maximize glucose production. with the aid of rsm, researchers can streamline the experimental design and significantly reduce the number of trials required, making the optimization process more efficient and cost-effective. furthermore, understanding the kinetics of the glucose production process is crucial for process design and control. the michaelis-menten model, a well-established enzyme kinetics model, can be applied to describe the enzymatic hydrolysis of cellulose and hemicellulose by aspergillus niger. by determining the kinetic parameters, such as the maximum reaction rate and the michaelis constant, researchers can gain valuable insights into the enzymatic efficiency and the overall process dynamics (efrinalia et al., 2022). comprehensive characterization of the feedstock is essential to comprehend the complex interactions between the microorganism and the substrate during glucose production. proximate and ultimate analyses provide information on the biomass composition, including moisture content, ash content, and elemental composition. energy-dispersive x-ray spectroscopy (edx) offers insights into the elemental distribution within the biomass. fourier-transform infrared spectroscopy (ftir) can reveal functional groups present in the biomass, aiding in understanding the structural changes during hydrolysis. scanning electron microscopy (sem) enables researchers to visualize the morphology and surface features of the feedstock, providing valuable information on structural changes and enzyme accessibility. the utilization of lignocellulosic biomass, such as sawdust, rice husk, and sugarcane bagasse, for glucose production using aspergillus niger holds immense promise as a sustainable approach to meet the demand for glucose (edor et al., 2018). the application of rsm and the michaelis-menten model will enhance process optimization and kinetic analysis, leading to improved glucose yields and process efficiency. additionally, a comprehensive characterization of the feedstock using techniques like edx, ftir, and sem will deepen the understanding of the enzymatic hydrolysis process and aid in optimizing the glucose production from these abundant biomass sources. overview of glucose as a biomolecule glucose, a monosaccharide with the chemical formula c6h12o6, is a fundamental biomolecule that plays a crucial role in various biological processes (mondal, 2018; rationalized, 2023). it serves as a primary source of energy for living organisms and serves as a building block for the synthesis of complex carbohydrates, lipids, and proteins. glucose is found in almost all living organisms, ranging from bacteria and plants to animals, including humans. it is a central player in cellular metabolism. through the process of glycolysis, glucose is https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 80 broken down into pyruvate, generating atp (adenosine triphosphate) molecules that provide energy for cellular functions (dienel, 2019; remesar & alemany, 2020). pyruvate can further undergo various metabolic pathways, such as the krebs cycle and oxidative phosphorylation, to produce additional atp through cellular respiration. glucose metabolism is essential for energy production, maintaining cellular homeostasis, and supporting vital cellular processes, such as signal transduction and membrane transport (parker, 2020). glucose serves as the primary energy source for most organisms. it is readily metabolized and efficiently converted into atp through glycolysis and subsequent respiratory pathways (dienel, 2019). the energy derived from glucose is utilized to perform mechanical work, maintain body temperature, support growth and development, and enable the functioning of vital organs and tissues (remesar & alemany, 2020). glucose serves as the building block for the synthesis of complex carbohydrates, including starch, glycogen, and cellulose (adams, 2022). through the process of polymerization, glucose molecules link together to form chains or branched structures, resulting in the formation of these carbohydrates. starch and glycogen serve as energy storage molecules in plants and animals, respectively, while cellulose provides structural support in plant cell walls. glucose is a precursor for the synthesis of various biomolecules (johns, 2021). it can be converted into other monosaccharides, such as fructose and galactose, through specific enzymatic reactions (riaukaite et al., 2019). glucose also serves as the starting point for the synthesis of lipids, amino acids, and nucleotides, which are essential components of cell membranes, proteins, and dna, respectively (rationalized, 2023). glucose concentration in the bloodstream is tightly regulated to maintain optimal physiological function (flores et al., 2018). in humans, the hormone insulin (ramos et al., 2021), produced by the pancreas, facilitates glucose uptake by cells, thereby reducing blood glucose levels. the hormone glucagon, also produced by the pancreas, acts in the opposite manner, promoting the release of stored glucose from glycogen, thereby increasing blood glucose levels. this intricate hormonal regulation ensures that cells have a constant supply of glucose for energy production (shirin et al., 2019). enzymatic hydrolysis of polysaccharides enzymatic hydrolysis is a biochemical process that involves the breakdown of complex polysaccharides into simpler sugars, primarily glucose, through the action of specific enzymes (weiss et al., 2019). this process plays a crucial role in the production of glucose from biomass, such as cellulose and starch, as it enables the efficient release of glucose units for various industrial applications. the choice of enzymes for enzymatic hydrolysis depends on the type of polysaccharide being targeted (amandio et al., 2023). cellulose, for example, requires cellulases, which are enzymes capable of breaking down the β-1,4-glycosidic bonds present in the cellulose chain (ilo, 2020). on the other hand, amylases are used to hydrolyze starch, targeting the α-1,4glycosidic bonds (hu et al., 2021). enzymes can be derived from various sources, including microorganisms (such as fungi and bacteria) or produced through recombinant dna technology. the selection of the appropriate enzyme(s) depends on factors such as substrate specificity, enzyme stability, cost, and availability (bhandari et al., 2021). the structure and composition of the polysaccharide substrate significantly influence the efficiency of enzymatic hydrolysis (amandio et al., 2023). factors such as the degree of polymerization, crystallinity, accessibility of the enzyme to the substrate, and the presence of inhibitors or lignin can affect the hydrolysis process. pretreatment methods, such as physical, chemical, or biological treatments, are often employed to enhance the accessibility of enzymes to the polysaccharide substrate, improving the overall hydrolysis efficiency (ansanay et al., 2021). enzymatic hydrolysis follows a complex kinetic process involving several steps, including enzyme-substrate adsorption, enzymatic reaction, and product desorption. the kinetics of https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 81 enzymatic hydrolysis can be described by various models, such as the michaelis-menten model or the langmuir-hinshelwood model. these models help in understanding the enzyme-substrate interactions, determining reaction rates, and estimating kinetic parameters such as the maximum reaction rate (vmax) and michaelis-menten constant (km) (efrinalia et al., 2022). kinetic studies provide valuable insights into the efficiency of the hydrolysis process and assist in process optimization. several factors influence the efficiency of enzymatic hydrolysis (turini et al., 2021): a) enzyme concentration: the amount of enzyme used affects the rate and extent of hydrolysis. higher enzyme concentrations generally lead to faster hydrolysis; however, there is an optimal enzyme dosage beyond which further enzyme addition may not yield significant improvements. b) substrate concentration: the concentration of the polysaccharide substrate affects the rate of hydrolysis. initially, as substrate concentration increases, the rate of hydrolysis also increases. however, at high substrate concentrations, the enzyme may become saturated, and the rate of hydrolysis may plateau. c) temperature and ph (jones et al., 2018): enzymatic activity is highly dependent on temperature and ph. different enzymes have specific temperature and ph optima for maximum activity. maintaining optimal temperature and ph conditions is crucial for achieving high enzymatic efficiency during hydrolysis. d) enzyme inhibitors (ascione et al., 2020): inhibitors, such as lignin, hemicelluloses, or degradation products, can negatively impact enzymatic hydrolysis. these inhibitors can interfere with enzymesubstrate interactions, reduce enzyme activity, or inhibit enzyme stability. strategies to minimize or mitigate the effects of inhibitors include enzymatic detoxification, inhibitor removal. acid hydrolysis of biomass acid hydrolysis is a chemical process that utilizes acid catalysts to break down complex carbohydrates in biomass into simpler sugars, including glucose (ilo, 2020). this process is an alternative to enzymatic hydrolysis and is particularly suitable for biomass with high cellulose or hemicellulose content. acid hydrolysis offers several advantages, such as faster reaction rates and the ability to handle a wide range of feedstocks. various acid catalysts can be used for biomass hydrolysis, with sulfuric acid (h2so4) and hydrochloric acid (hcl) being the most commonly employed. these strong acids dissociate in water, providing hydrogen ions (h+) that catalyze the hydrolysis of glycosidic bonds. the choice of acid catalyst depends on factors such as reaction efficiency, cost, safety, and the downstream processing of the hydrolysate (swiatek et al., 2020). optimizing reaction conditions is crucial for achieving efficient acid hydrolysis (zhang & sutheerawattananonda, 2020). factors such as temperature, acid concentration, reaction time, and solid-toliquid ratio need to be carefully controlled. elevated temperatures generally increase reaction rates, but excessively high temperatures can lead to sugar degradation (astuti et al., 2018). acid concentration influences the rate of hydrolysis, with higher concentrations promoting faster reaction rates. however, high acid concentrations may also result in the formation of inhibitory compounds and increase the risk of corrosion. reaction time is determined based on the kinetics of hydrolysis, and the solid-to-liquid ratio affects the accessibility of acids to the biomass substrate. during acid hydrolysis, the acid catalysts protonate the glycosidic bonds, leading to their cleavage (nguyen et al., 2018). the hydrolysis of cellulose and hemicellulose follows different reaction pathways. cellulose hydrolysis involves the cleavage of β-1,4-glycosidic bonds, resulting in the formation of glucose monomers (nguyen et al., 2018; remesar & alemany, 2020). hemicellulose, composed of various sugar monomers, undergoes acid-catalyzed hydrolysis to produce a mixture of different sugars. however, acid hydrolysis is more challenging for lignin, a complex and highly resistant polymer, which typically undergoes minimal degradation during acid hydrolysis (zhang et al., 2023). https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 82 despite its advantages, acid hydrolysis also presents certain challenges (damayanti et al., 2021; swiatek et al., 2020): i. corrosion and safety: strong acids like sulfuric acid can be corrosive and require proper handling and safety precautions. the selection of appropriate equipment and materials is essential to withstand the corrosive nature of acids. ii. sugar degradation: the hydrolysis process, especially at high temperatures and acid concentrations, can lead to the degradation of sugars into unwanted byproducts, such as furans and organic acids. this degradation reduces the overall yield of desired glucose and can interfere with downstream processes. iii. inhibitor formation: acid hydrolysis can generate inhibitory compounds, including furfural, 5hydroxymethylfurfural (hmf), and organic acids, which can affect subsequent enzymatic or microbial conversion processes (katarzyna et al., 2020; muhammad et al., 2022; sant et al., 2021; swiatek et al., 2020). detoxification methods, such as neutralization, washing, or adsorption, may be required to minimize the impact of inhibitors. iv. acid recovery and neutralization: after hydrolysis, the acid needs to be separated from the hydrolysate for reuse or neutralization. acid recovery and neutralization methods are important for cost-effectiveness, environmental considerations, and the overall sustainability of the process. despite the challenges, acid hydrolysis remains an important method for biomass conversion due to its versatility and ability to handle a wide range of feedstocks. it offers advantages such as faster reaction rates, scalability, and the potential to utilize various biomass sources. researchers continue to explore process optimization strategies to improve acid hydrolysis efficiency, minimize sugar degradation, and reduce the formation of inhibitory compounds. to address some of the challenges associated with acid hydrolysis, several advancements have been made. for instance, the use of milder acids or catalysts, such as organic acids or solid acid catalysts, has been explored to mitigate corrosion and improve the selectivity of hydrolysis. additionally, the integration of acid hydrolysis with other pretreatment techniques, such as steam explosion or liquid hot water treatment, has shown promise in enhancing hydrolysis efficiency and reducing inhibitor formation (fu et al., 2018; li et al., 2019). fermentation of sugars for glucose production fermentation is a biological process in which microorganisms, such as yeasts or bacteria, convert sugars into various products, including ethanol, organic acids, and gases. the fermentation of sugars plays a significant role in glucose production, as it provides an alternative route for converting sugars derived from biomass or other feedstocks into glucose (damayanti et al., 2021). various microorganisms are employed in fermentation processes to convert sugars to glucose. yeasts, such as saccharomyces cerevisiae, are commonly used for ethanol production (halka et al., 2018). they possess the ability to metabolize glucose through the glycolysis pathway, producing ethanol as the primary end product. other microorganisms, such as lactic acid bacteria or certain species of escherichia coli, can ferment sugars to produce organic acids like lactic acid or acetic acid (gunkova et al., 2021). the selection of microorganisms depends on the desired end product and the specific requirements of the fermentation process (behera et al., 2019). the fermentation of sugars involves several stages, including sugar preparation, inoculum development, fermentation, and product recovery (damayanti et al., 2021). the sugar source, such as glucose, fructose, or sucrose, is prepared by hydrolysis of biomass or through other pretreatment methods (kiš et al., 2019). the microorganisms are then introduced into the fermentation medium, which provides the necessary nutrients and environmental conditions for their growth and metabolism. the fermentation process is carried out under controlled conditions of temperature, ph, and https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 83 aeration (jones et al., 2018). as the microorganisms metabolize the sugars, they produce glucose as an intermediate or end product, depending on the specific fermentation pathway (teleky et al., 2020). several factors influence the efficiency of fermentation for glucose production (chang et al., 2018; jones et al., 2018; kanagasabai et al., 2019; tse et al., 2021): a) sugar concentration: the concentration of sugars in the fermentation medium affects the rate and extent of glucose production. higher sugar concentrations can lead to faster fermentation rates but may also result in inhibitory effects on microbial growth and metabolism. b) microbial strain and characteristics: the selection of an appropriate microbial strain is critical for efficient glucose production. different strains may exhibit variations in sugar utilization, fermentation rates, and tolerance to inhibitors. genetic engineering approaches can be employed to enhance the metabolic capabilities of microorganisms for glucose production. c) nutrient availability: microorganisms require essential nutrients, such as nitrogen, phosphorus, and trace elements, for their growth and fermentation activity. optimizing nutrient availability through appropriate medium formulation is crucial for maximizing fermentation efficiency. d) environmental conditions: temperature, ph, and oxygen availability are important environmental factors that impact microbial growth and fermentation. each microorganism has an optimal range of these parameters, and maintaining the appropriate conditions ensures efficient fermentation and glucose production. e) inhibitors and byproducts: inhibitory compounds, such as organic acids, furans, or phenolic compounds, can be generated during biomass pretreatment or hydrolysis processes. these inhibitors can affect microbial growth and fermentation efficiency. detoxification strategies, including physical, chemical, or biological methods, can be implemented to minimize their impact. glucose produced through fermentation has diverse applications in various industries: glucose fermentation to ethanol serves as a key process in biofuel production (smachetti et al., 2018). ethanol can be used as a transportation fuel or as a blending component in gasoline, reducing reliance on fossil fuels and contributing to a more sustainable energy sector (inyang et al., 2022; salim, gonzález-garcía, et al., 2019). glucose is widely used in the food and beverage industry as a sweetener, preservative, or fermentation substrate. it serves as a key ingredient in the production of baked goods, confectionery, beverages, and fermented products such as beer, wine, and spirits. glucose is utilized as a carbon source for the production of various pharmaceuticals, including antibiotics, vitamins, amino acids, and therapeutic proteins (simpson et al., 2022). it also serves as a precursor for the synthesis of bioactive compounds and pharmaceutical intermediates. glucose can be further converted into a wide range of valuable chemicals, such as organic acids (e.g., lactic acid, citric acid), polyols (e.g., sorbitol, mannitol), and other platform chemicals (nam, 2022). these chemicals find applications in the production of polymers, resins, solvents, and other industrial products. glucose can be used as an energy source and nutrient supplement in animal feed formulations. it provides readily available energy for livestock and poultry, supporting their growth and production. in agriculture, glucose-based products can be utilized as plant growth regulators, biofertilizers, or biostimulants, enhancing crop yield and quality (blanco et al., 2020; roslan & salimi, 2019). bioplastics and biomaterials: glucose serves as a building block for the production of bioplastics, such as polylactic acid (pla), which offers a renewable and biodegradable alternative to conventional plastics. glucose-based polymers can also be employed in the development of biomaterials for tissue engineering, drug delivery systems, and other biomedical applications (far et al., 2022; seddiqi et al., 2021; sood et al., 2021). the fermentation of sugars for glucose production offers a versatile and sustainable approach to utilize biomass resources and generate valuable products. advances in microbial engineering, fermentation process https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 84 optimization, and downstream processing techniques continue to enhance the efficiency and economic viability of glucose production through fermentation. furthermore, the integration of fermentation with other biorefinery processes allows for the utilization of diverse feedstocks and the production of a wide range of valuable compounds, contributing to the development of a bio-based economy and a more sustainable future (salim, et al., 2019). comparison of different biochemical processes biochemical processes for glucose production encompass various methods, including enzymatic hydrolysis, acid hydrolysis, and fermentation. each of these processes has its advantages, challenges, and suitability for different feedstocks and applications. the efficiency of a biochemical process is measured by the yield of glucose obtained from the feedstock (kadhum et al., 2019). enzymatic hydrolysis, utilizing specific enzymes, can achieve high conversion rates of polysaccharides into glucose. however, it may require longer reaction times and can be costlier due to the need for enzyme production. acid hydrolysis, on the other hand, offers faster reaction rates but may lead to lower glucose yields due to sugar degradation and formation of inhibitory compounds. fermentation processes can also achieve high conversion efficiencies, particularly when optimized for specific microorganisms and conditions (recek et al., 2018). different biochemical processes have varying compatibilities with different feedstocks. enzymatic hydrolysis is well-suited for a wide range of biomass sources, including lignocellulosic materials, due to its specificity and ability to target specific polysaccharides (weiss et al., 2019). acid hydrolysis can handle diverse feedstocks as well, but certain biomass components, such as lignin, may hinder the process efficiency. fermentation processes generally require sugars or sugar-rich feedstocks and are commonly used for glucose production from agricultural crops, sugar cane, or molasses (nwankwo & ukpabi, 2018). the environmental impact of a biochemical process is a crucial consideration in sustainable production. enzymatic hydrolysis, being a biologically driven process, is considered environmentally friendly. it operates under mild conditions, produces fewer byproducts, and has lower energy requirements compared to other processes. acid hydrolysis, while effective, requires the use of strong acids and may generate waste streams containing inhibitory compounds, necessitating proper treatment and disposal. fermentation processes can also be environmentally favorable, especially when utilizing renewable feedstocks and optimizing process parameters to minimize waste and energy consumption (salim, et al., 2019). the purity of glucose obtained from a biochemical process is important, particularly for applications in the food, pharmaceutical, and chemical industries. enzymatic hydrolysis generally yields high-purity glucose, as specific enzymes target the desired polysaccharides without introducing contaminants (codato-zumpano et al., 2023). acid hydrolysis may result in lower product purity due to the presence of inhibitory compounds or degradation products. fermentation processes can produce glucose along with other metabolites, requiring additional purification steps to obtain high-purity glucose (salim, et al., 2019). the economics of a biochemical process depend on factors such as capital and operating costs, feedstock availability and cost, yield, and market demand for the products. enzymatic hydrolysis, although efficient, can be costlier due to the requirement for enzymes and longer reaction times (weiss et al., 2019). acid hydrolysis offers faster reaction rates but may incur additional costs for acid procurement and disposal of waste streams. fermentation processes, while efficient and commercially viable for certain feedstocks, may require downstream processing and purification steps, impacting overall process economics (recek et al., 2018). https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 85 locally sourced materials for glucose production the utilization of locally sourced materials for glucose production offers several advantages, including reduced transportation costs, increased sustainability, and support for local economies (cheng et al., 2019). locally available biomass resources can serve as valuable feedstocks for biochemical processes, contributing to the production of glucose in a more efficient, cost-effective, and environmentally friendly manner (inyang et al., 2022). agricultural residues as feedstock agricultural residues consist of the non-edible parts of crops that remain after harvest or processing (kim et al., 2018). they typically contain a combination of cellulose, hemicellulose, lignin, and other minor components. the exact composition varies depending on the type of residue and the specific crop. cellulose and hemicellulose are polysaccharides that can be hydrolyzed into glucose, while lignin provides structural support to the plant and is more challenging to break down (jeoh et al., 2017). agricultural residues are widely available due to the large-scale agricultural activities in many regions. the abundance of these residues makes them attractive feedstocks for glucose production, as they provide a renewable and sustainable resource that can be utilized without competing with food production. the availability of agricultural residues can vary based on factors such as crop type, geographic location, and local agricultural practices. preprocessing and pretreatment: before agricultural residues can be used as feedstocks for glucose production, preprocessing and pretreatment steps may be required. preprocessing involves activities such as size reduction (e.g., grinding, chopping) and drying to enhance the feedstock's processability (prithviraj et al., 2020). pretreatment methods, such as steam explosion, liquid hot water treatment, or acid pretreatment, can be applied to enhance the accessibility of cellulose and hemicellulose for subsequent hydrolysis (li et al., 2019; shukla et al., 2023). enzymatic hydrolysis is a commonly employed method for converting agricultural residues into glucose. specific enzymes, such as cellulases and hemicellulases, are used to break down the cellulose and hemicellulose components into glucose (jayasekara & ratnayake, 2019). enzymatic hydrolysis offers several advantages, including high selectivity, mild operating conditions, and compatibility with a wide range of agricultural residues. however, the cost of enzymes and the need for longer reaction times are considerations for process economics. acid hydrolysis can also be used to convert agricultural residues into glucose. strong acids, such as sulfuric acid or hydrochloric acid, are typically employed to break down the polysaccharides into their constituent sugars (adeoye et al., 2019). acid hydrolysis offers faster reaction rates compared to enzymatic hydrolysis. however, it may lead to sugar degradation, formation of inhibitory compounds, and corrosion issues, requiring proper process optimization and waste management strategies. to maximize glucose production from agricultural residues, process optimization and integration strategies can be employed (kiran & trzcinski, 2017). this includes optimizing factors such as temperature, ph, residence time, enzyme loading (in enzymatic hydrolysis), acid concentration (in acid hydrolysis), and solid-liquid ratios. integration with other pretreatment techniques or biorefinery concepts, such as combining acid hydrolysis with fermentation or utilizing lignin coproducts, can enhance overall process efficiency and resource utilization. the utilization of agricultural residues as feedstocks for glucose production offers several sustainability benefits (oyola-rivera et al., 2018). it reduces waste generation, maximizes the use of available biomass resources, and contributes to the development of a circular economy. additionally, utilizing agricultural residues for bio-based processes helps reduce greenhouse gas emissions by replacing fossil-based feedstocks and minimizing reliance on non-renewable resources. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 86 forest biomass and lignocellulosic materials forest biomass and lignocellulosic materials consist mainly of cellulose, hemicellulose, and lignin, along with smaller amounts of extractives and ash. cellulose and hemicellulose are polysaccharides that can be hydrolyzed into glucose, while lignin provides structural support to the plant and contributes to the recalcitrance of lignocellulosic materials. the exact composition varies depending on factors such as tree species, age, and growing conditions (augusto & boca, 2022). forest biomass and lignocellulosic materials are abundant and widely available in regions with significant forest resources. they can be sourced from various forestry operations, including timber harvesting, sawmills, and forest management activities. the availability of forest biomass depends on factors such as forest management practices, land-use policies, and sustainability considerations to ensure responsible sourcing. before forest biomass and lignocellulosic materials can be used as feedstocks for glucose production, preprocessing and pretreatment steps are typically necessary (jones et al., 2018). preprocessing involves activities such as chipping or grinding to reduce the size of the biomass and enhance its processability. pretreatment methods, such as steam explosion, acid pretreatment, or organosolv processes, are often employed to disrupt the lignocellulosic structure and increase the accessibility of cellulose and hemicellulose for subsequent hydrolysis (ansanay et al., 2021). enzymatic hydrolysis is a widely used method for converting forest biomass and lignocellulosic materials into glucose (zhou et al., 2023). specific enzymes, such as cellulases and hemicellulases, are employed to break down the cellulose and hemicellulose components into glucose. enzymatic hydrolysis offers high selectivity, mild operating conditions, and compatibility with various lignocellulosic materials. however, factors such as enzyme cost, enzyme stability, and the presence of inhibitory compounds from pretreatment may impact the efficiency and economics of the process (li et al., 2019). acid hydrolysis can also be employed for glucose production from forest biomass and lignocellulosic materials. strong acids, such as sulfuric acid or hydrochloric acid, are used to hydrolyze the polysaccharides into their constituent sugars. acid hydrolysis offers faster reaction rates compared to enzymatic hydrolysis. however, it may lead to sugar degradation, formation of inhibitory compounds, and corrosiveness issues, necessitating careful process optimization and waste management strategies (codato-zumpano et al., 2023). to maximize glucose production from forest biomass and lignocellulosic materials, process optimization and integration strategies can be implemented. this includes optimizing factors such as temperature, acid concentration (in acid hydrolysis), residence time, solid-liquid ratios, and pretreatment conditions. integration with other biorefinery processes, such as lignin valorization, fermentation, or co-production of other value-added products, can enhance the overall process efficiency, resource utilization, and economic viability (okonkwo et al., 2022). algal biomass as a potential source algal biomass consists of various components, including proteins, lipids, carbohydrates, pigments, vitamins, and minerals. the carbohydrate fraction, which includes glucose and other sugars, can be extracted and utilized for glucose production (ruiz et al., 2020). the exact composition of algal biomass varies depending on the algal species, cultivation conditions, and growth phase. algae are found in diverse aquatic environments, including freshwater, marine, and brackish water systems. they can be cultivated in open ponds, closed photobioreactors, or other specialized systems. algal biomass has the potential to be an abundant and renewable feedstock due to the high growth rates of certain algal species and their ability to utilize sunlight and carbon dioxide for photosynthesis (yang et al., 2023). algal biomass can be cultivated using different cultivation systems and techniques. open pond systems involve the cultivation of algae in large, shallow ponds exposed to sunlight. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 87 closed photobioreactors provide a controlled environment, allowing for precise control of parameters such as temperature, light intensity, and nutrient availability. algal cultivation requires appropriate nutrient supply, including carbon dioxide, nitrogen, phosphorus, and micronutrients, to support optimal growth and carbohydrate accumulation (de souza et al., 2019). once the algal biomass has reached the desired growth stage, it needs to be harvested and processed to extract the carbohydrates, including glucose (huo et al., 2022). harvesting methods may include mechanical methods (e.g., centrifugation, filtration) or physicochemical methods (e.g., flocculation, sedimentation) to separate the algae from the growth medium. after harvesting, the biomass can undergo further processing steps, such as cell disruption, dewatering, and extraction, to obtain the desired carbohydrate fraction (hamman et al., 2018). glucose production from algal biomass can be achieved through enzymatic hydrolysis or acid hydrolysis methods, similar to other biomass feedstocks. enzymatic hydrolysis involves the use of specific enzymes, such as cellulases and hemicellulases, to break down the carbohydrates into glucose (de souza et al., 2019). acid hydrolysis utilizes strong acids, such as sulfuric acid or hydrochloric acid, to hydrolyze the carbohydrates. the choice of hydrolysis method depends on factors such as the algal species, biomass composition, process economics, and desired end products. algal biomass holds significant potential as a sustainable feedstock for glucose production. algae have a high photosynthetic efficiency and can utilize carbon dioxide, thus contributing to carbon capture and potentially mitigating greenhouse gas emissions. algal cultivation can also be integrated with wastewater treatment, nutrient recycling, and the production of other value-added products such as biofuels, bioplastics, or animal feed (ruiz et al., 2020). however, certain considerations, such as water and nutrient requirements, cultivation system scalability, and potential ecological impacts, should be carefully addressed to ensure the sustainability of algal biomass utilization. food waste and byproducts food waste and byproducts comprise organic materials from agricultural, processing, distribution, and consumption activities. these include fruit and vegetable peels, trimmings, discarded grains, food processing residues, expired products, and other food-related waste. the composition of food waste and byproducts can vary greatly, but they often contain significant amounts of carbohydrates, including glucose and other sugars, along with proteins, lipids, fibers, and other nutrients (okonkwo et al., 2022). food waste and byproducts are abundant and readily available throughout the food supply chain. they arise from various sources, including households, restaurants, food processing facilities, and retail sectors. the quantity and availability of food waste and byproducts depend on factors such as consumption patterns, food handling practices, and waste management systems. efficient utilization of these materials not only reduces waste but also contributes to a circular economy and resource conservation (yu et al., 2022). prior to glucose production, food waste and byproducts may require preprocessing and pretreatment steps. preprocessing involves sorting, cleaning, and potentially size reduction to remove non-biodegradable components and improve processability. pretreatment methods, such as enzymatic or acid hydrolysis, can be employed to break down complex carbohydrates and enhance the release of glucose (zhou et al., 2023). additionally, degrading enzymes or microbial fermentation may be utilized to convert more complex food waste components into glucose or other valuable products. enzymatic hydrolysis is a common method for converting food waste and byproducts into glucose. specific enzymes, such as carbohydrases, can be employed to break down the complex carbohydrates present in these materials (yu et al., 2022). enzymatic hydrolysis offers high selectivity, mild operating conditions, and compatibility with a wide range of food waste and byproduct feedstocks. however, factors such as enzyme cost, enzymatic stability, and the presence of inhibitory compounds from the waste stream may affect process https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 88 efficiency and economics. acid hydrolysis can also be utilized for glucose production from food waste and byproducts. strong acids, such as sulfuric acid or hydrochloric acid, are used to break down the carbohydrates into their constituent sugars. acid hydrolysis offers faster reaction rates compared to enzymatic hydrolysis and can handle a broader range of feedstocks (ebikade et al., 2018). however, it requires careful control to prevent sugar degradation and the formation of inhibitory compounds, and appropriate waste management strategies are essential due to the corrosive nature of the acids. to maximize glucose production from food waste and byproducts, process optimization and integration strategies are crucial. this includes optimizing factors such as temperature, ph, residence time, acid concentration (in acid hydrolysis), enzyme loading (in enzymatic hydrolysis), and solid-liquid ratios. integration with other processes, such as anaerobic digestion for biogas production (abubakar et al., 2022), can further enhance resource utilization and overall process efficiency, reducing waste and generating additional value from food waste and byproducts. comparison of different feedstock sources when considering glucose production, various feedstock sources can be utilized, each with its own characteristics and considerations. agricultural residues, such as crop straw, corn stover, and sugarcane bagasse, are abundant and widely available (schiano et al., 2022). they do not compete with food production, making them a sustainable and renewable feedstock option. agricultural residues often have high cellulose and hemicellulose content, which can be efficiently hydrolyzed into glucose. agricultural residues may require preprocessing and pretreatment to enhance their processability and increase sugar accessibility (jones et al., 2018). some residues have high lignin content, which adds to the recalcitrance and complexity of the feedstock (blanco et al., 2020). proper waste management and logistics are essential to ensure a consistent and reliable supply. forest biomass and lignocellulosic materials, including wood chips, sawdust, and logging residues, offer a sustainable feedstock source (blanco et al., 2020). they are abundant, widely available, and can be sourced from managed forests. forest biomass contains significant amounts of cellulose, which can be converted into glucose (selivanov et al., 2023). additionally, lignocellulosic materials can be integrated with the production of other value-added products, such as biofuels or bioplastics. preprocessing and pretreatment are often required to overcome the recalcitrance of lignocellulosic materials (elalami et al., 2022). supply chain logistics and sustainability considerations, including responsible forest management practices, need to be addressed. the presence of lignin may affect the efficiency of glucose production and downstream. algal biomass presents a renewable and highly productive feedstock source for glucose production. algae can be cultivated in various aquatic environments and have the potential to achieve high growth rates and carbon dioxide fixation. some algae species accumulate significant amounts of carbohydrates, including glucose, which can be extracted and utilized (ruiz et al., 2020; smachetti et al., 2018). algal cultivation can be integrated with wastewater treatment and other biorefinery processes. algal cultivation requires careful management of nutrients, including carbon dioxide, nitrogen, and phosphorus, to achieve optimal growth and carbohydrate accumulation. scalability and cost-effectiveness of large-scale cultivation systems remain challenges (zhang et al., 2020). harvesting and processing methods for algal biomass can be energy-intensive and require further development for cost reduction (moreira et al., 2019). food waste and byproducts offer a readily available and abundant feedstock source for glucose production (schiano et al., 2022). they can be sourced from various stages of the food supply chain, reducing waste and contributing to a circular economy. food waste often contains significant amounts of carbohydrates, including glucose, making it an attractive feedstock option. food waste and byproducts may require preprocessing, https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 89 sorting, and potential pretreatment to remove non-biodegradable components and enhance processability (elalami et al., 2022). the composition of food waste can be diverse and variable, requiring tailored processing approaches. waste collection, handling, and logistics need to be efficiently managed to ensure a reliable and uncontaminated feedstock supply. sugarcane bagasse, rice husk and sawdust application producing glucose from sugarcane bagasse involves breaking down the complex carbohydrates present in the bagasse into simpler sugars like glucose. sugarcane bagasse is the fibrous residue left after extracting the juice from sugarcane stalks in the sugar extraction process. it is rich in cellulose and hemicellulose, both of which can be converted into glucose through different processes. general outline of the process to produce glucose from sugarcane bagasse include preparation of sugarcane bagasse, pretreatment, enzymatic hydrolysis, fermentation, separation and purification and glucose concentration. previous work done using the feedstock to produce glucose are found in roslan & salimi (2019), lv et al. (2022) and bussamra et al. (2020). glucose produced from rice husk can find applications in various industries, similar to glucose produced from other lignocellulosic biomass sources. some potential applications include bioethanol production, food and beverage industry, pharmaceutical and nutraceutical industries, chemical feedstock and bioplastics (dhar et al., 2019). it's essential to consider that the advantages of glucose production from rice husk depend on various factors, including local agricultural practices, feedstock availability, infrastructure, and the specific application of the glucose produced. both rice husk and sugarcane bagasse have their unique characteristics, and the choice of feedstock would depend on the specific circumstances and objectives of the glucose production process. production of glucose from rice husk will also follow the same process steps listed under sugarcane bagasse utilization, beginning with pretreatment (aredo et al., 2020; bohn et al., 2021; cheoh, 2018). the same author also adopts a unique model called the peleg kinetic model to determine the reaction rate constant. more details are found in asim et al. (2021) who analyzed the production of food-grade glucose using wheat residues and rice waste. on the other hand, there is limited utilization of sawdust to produce glucose. one among previous studies (within 2018-2023) discovered is a study by hassan et al. (2018). microorganism strain for hydrolysis biodegradation is the application of biological principle for the purpose of converting food stuff into more palatable nutritional or staple food; it has the potential to improve the nutritional value of fibrous agricultural by-product. enzymatic hydrolysis of cellulose is carried out by enzyme which is highly specific. aspergillus niger is worldwide in distribution and has been isolated from numerous habitat. humans are continually exposed to aspergillus niger spores and vegetative forms on foodstuffs and in air. the vast majority of aspergillus niger strains especially those used in industrial fermentation have a history of safe use (edor et al., 2018). some species of the fungal genus aspergillus produce glucoamylase enzymes that can break down starches into glucose. these enzymes are widely used in various industries for starch hydrolysis and glucose production. apart from aspergillus niger chosen by this study, several other microorganism strains such as escherichia coli may be used (carreón-rodríguez et al., 2023). methodology initial literature review was earlier reported in two sections: 2.1 and 2.2. of concern to bioengineers is the speed of these production and product optimization. in view of that, kinetics and optimization strategies were well https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 90 discussed using sourced materials, including, book chapters, thesis, journals, book and conference papers. usually, a good kinetics study and optimized production of glucose will translate into experts venturing into its manufacture for sustainable growth and benefits that can be driven from it. thus, the expected results discuss techno-economic analysis, cost, life cycle assessment, and case studies for its industrial application. kinetics of glucose production the kinetics of glucose production refers to the study of the rates and mechanisms involved in the conversion of different feedstocks into glucose. understanding the kinetics is essential for optimizing process conditions, designing reactors, and predicting glucose yields. several factors influence the kinetics of glucose production, including the type of feedstock, hydrolysis method, enzyme or acid concentration, temperature, ph, and reaction time (ude et al., 2020). these factors affect the reaction rates by influencing the accessibility of carbohydrates, the catalytic activity of enzymes or acids, and the solubility and stability of the intermediates and products (sodiqovna, 2020). optimal process conditions need to be determined to achieve high glucose yields and conversion rates. the kinetics of glucose production can involve different reaction mechanisms depending on the hydrolysis method used. in enzymatic hydrolysis, specific enzymes, such as cellulases and hemicellulases, break down the polysaccharides into glucose molecules through enzymatic cleavage of glycosidic bonds (hu et al., 2021; ilo, 2020). the reaction typically follows a complex mechanism involving substrate adsorption, enzymatic reaction, and product desorption. acid hydrolysis, on the other hand, involves the hydrolysis of carbohydrates by strong acids (andreeva et al., 2021), resulting in the cleavage of glycosidic bonds and the release of glucose. mathematical models are widely used to describe and predict the kinetics of glucose production. these models can be based on empirical correlations, mechanistic principles, or a combination of both. empirical models use experimental data to develop correlations between process variables and glucose production rates. mechanistic models (richter et al., 2022; salazar et al., 2023), on the other hand, are based on the understanding of reaction mechanisms and the application of mass balance and rate equations. these models can provide insights into the underlying reaction kinetics and aid in process optimization and reactor design. the determination of reaction rates is crucial for understanding the kinetics of glucose production. experimental techniques such as batch assays, continuous flow reactors, or spectroscopic methods can be employed to measure the rates of glucose release or consumption (halka et al., 2018). by varying process parameters such as enzyme or acid concentration, temperature, or reaction time, the rates can be determined and used to estimate reaction rate constants and activation energies. kinetic modeling involves the development of mathematical equations that describe the rates of glucose production as a function of various process variables. model parameters, such as reaction rate constants and activation energies, can be estimated by fitting the model to experimental data using optimization techniques. parameter estimation methods (murzin et al., 2021; yu et al., 2021), such as nonlinear regression or kinetic modeling software, can be employed to obtain accurate parameter values and validate the model's predictive capabilities. the kinetics of glucose production play a crucial role in process optimization. by studying the reaction rates and understanding the underlying mechanisms, process conditions can be optimized to maximize glucose yields, conversion rates, and process efficiency (bryan et al., 2018; toif et al., 2021). kinetic studies also provide insights into the effects of different variables, allowing for the identification of limiting factors and the determination of optimal operating conditions. table 1 are literature summary of previous work on glucose production. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 91 table 1: literature review on glucose production methodologies author microorganism and/or feedstock method glucose yield condition (ude et al., 2020) 0.428 g/50 ml enzyme + mixed peels (cassava & potato) kinetic of hydrolysis: michaelis-menten model;

shokrkar & ebrahimi, 2021). (a) michaelis-menten model: the michaelis-menten model is one of the most widely used kinetic models for enzymatic reactions, including enzymatic hydrolysis. it assumes that the reaction rate is proportional to the concentration of the enzyme-substrate complex. the model incorporates two parameters: the maximum reaction rate (𝑉𝑚𝑎𝑥) and the michaelis constant (𝐾𝑚), which represents the substrate concentration at which the reaction rate is half of vmax. the michaelis-menten model is based on the assumption of steady-state enzyme kinetics and assumes that the enzyme-substrate complex is the rate-determining step. (b) briggs-haldane model: the briggs-haldane model is an extension of the michaelis-menten model and considers the reversible formation of the enzyme-substrate complex. it incorporates an additional parameter, the dissociation constant (𝐾𝑑), which represents the equilibrium constant between the enzymesubstrate complex and the free enzyme and substrate. the briggs-haldane model provides a more accurate representation of the enzymatic hydrolysis process by considering the reversible nature of the enzymesubstrate interaction. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 92 (c) hanes-woolf model: the hanes-woolf model is an alternative representation of the michaelis-menten equation. it linearizes the relationship between the reaction rate and the substrate concentration by plotting the ratio of the substrate concentration to the reaction rate against the substrate concentration. the slope of the linear plot represents the michaelis constant (𝐾𝑚 ), and the intercept on the y-axis represents the reciprocal of the maximum reaction rate (1/𝑉𝑚𝑎𝑥). the hanes-woolf model is particularly useful when experimental data have high variability or at low substrate concentrations. (d) luedeking-piret model: the luedeking-piret model is a phenomenological model that describes the relationship between the production rate of glucose and the consumption rate of the substrate. it assumes that both the glucose production and substrate consumption rates are dependent on the concentration of the substrate and the enzyme. the model incorporates two parameters: the luedeking-piret coefficient (α), which represents the extent of glucose production independent of substrate consumption, and the luedeking-piret coefficient (β), which represents the fraction of substrate consumed in relation to glucose production. (e) substrate inhibition model: the substrate inhibition model accounts for the inhibition of the enzymatic reaction at high substrate concentrations. it assumes that the reaction rate decreases at high substrate concentrations due to the inhibitory effect of the excess substrate. the model incorporates an additional parameter, the inhibition constant (𝐾𝑖), which represents the substrate concentration at which the reaction rate is half of the maximum reaction rate. the substrate inhibition model is particularly relevant when working with concentrated substrate solutions. (f) modified kinetic models: in addition to the aforementioned models, various modified kinetic models have been proposed to account for specific factors and phenomena in enzymatic hydrolysis. these include models considering enzyme deactivation, enzyme substrate heterogeneity, multiple enzyme activities, and product inhibition. these modified models provide a more comprehensive representation of the enzymatic hydrolysis process by considering additional factors that can influence reaction rates and glucose yields. kinetic models for enzymatic hydrolysis provide valuable insights into the reaction mechanisms, reaction rates, and optimal process conditions for glucose production. by fitting the models to experimental data using parameter estimation techniques (shokrkar & ebrahimi, 2021; yu et al., 2021), the kinetic parameters can be determined, enabling the prediction of glucose yields and the optimization of enzymatic hydrolysis processes. however, it is important to note that the selection and applicability of a specific kinetic model depend on the characteristics of the enzyme-substrate system and the specific objectives of the study (panda & datta, 2022). kinetic models for acid hydrolysis kinetic models for acid hydrolysis are mathematical representations that describe the rates of glucose production from the hydrolysis of polysaccharides by strong acids (yuan et al., 2021). these models are valuable tools for understanding the acid hydrolysis process, optimizing reaction conditions, and predicting glucose yields. discussion on some commonly used kinetic models for acid hydrolysis, their assumptions, and their applications are found below. (i) first-order kinetic model: the first-order kinetic model is a simple and widely used model for acid hydrolysis. it assumes that the reaction rate is directly proportional to the concentration of the substrate (polysaccharide) or the acid. the model equation 1 is given by onyelucheya et al. (2022): https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 93 rate = k[substrate] (1) where rate represents the reaction rate, k is the rate constant, and [substrate] is the concentration of the substrate. the first-order kinetic model assumes that the acid hydrolysis reaction follows pseudo-first-order kinetics, where the concentration of the acid is maintained at a sufficiently high level. (ii) pseudo-first-order kinetic model the pseudo-first-order kinetic model is an extension of the first-order model that accounts for the effect of both substrate and acid concentrations on the reaction rate. the model equation is given by equation 2: rate = k[substrate][acid] (2) where rate represents the reaction rate, k is the rate constant, [substrate] is the concentration of the substrate, and [acid] is the concentration of the acid. the pseudo-first-order kinetic model assumes that the reaction rate is dependent on both the substrate and acid concentrations. (iii) second-order kinetic model the second-order kinetic model considers the simultaneous reaction of two reactants, the substrate and the acid. the model equation is given by equation 3: rate = k[substrate][acid] (3) where rate represents the reaction rate, k is the rate constant, [substrate] is the concentration of the substrate, and [acid] is the concentration of the acid. the second-order kinetic model assumes that the reaction rate is proportional to the product of the substrate and acid concentrations. (iv) fractional conversion kinetic model the fractional conversion kinetic model describes the conversion of the substrate into glucose as a function of time. it assumes that the reaction rate is proportional to the remaining concentration of the substrate. the model equation is given by equation 4: 𝑋 = 1 − 𝑒−𝑘𝑡 (4) where x represents the fractional conversion of the substrate, k is the rate constant, t is the reaction time, and e is the base of the natural logarithm. the fractional conversion kinetic model is useful for monitoring the progress of acid hydrolysis reactions and estimating the extent of substrate conversion. (v) modified kinetic models various modified kinetic models have been proposed to account for specific factors and phenomena in acid hydrolysis, such as temperature dependence, catalytic effects of acid, and inhibition effects. these models incorporate additional parameters or variables to improve the accuracy of the predictions and provide a more comprehensive representation of the acid hydrolysis process. kinetic models for acid hydrolysis provide insights into the reaction rates, reaction mechanisms, and optimal process conditions for glucose production (efrinalia et al., 2022). by fitting these models to experimental data using parameter estimation techniques (salmi et al., 2020; yu et al., 2021), the kinetic parameters can be https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 94 determined, enabling the prediction of glucose yields and the optimization of acid hydrolysis processes. however, it is important to consider the limitations of these models and the specific characteristics of the acid hydrolysis system being studied when selecting and applying a particular kinetic model (yuan et al., 2021). kinetic models for fermentation processes kinetic models for fermentation processes are mathematical representations that describe the rates of glucose consumption and product formation during the conversion of sugars into various products, such as ethanol, organic acids, or biofuels, by microorganisms. these models are crucial for understanding the fermentation kinetics, optimizing process conditions, and predicting product yields. in this section, we will discuss some commonly used kinetic models for fermentation processes, their assumptions, and their applications. a) monod model the monod model is a widely used kinetic model for microbial fermentation processes. it describes the specific growth rate of microorganisms as a function of substrate concentration. the model equation is given by gonzález-figueredo et al. (2017) in equation 5: 𝜇 = 𝜇𝑚𝑎𝑥𝑆 𝐾𝑠+𝑆 (5) where μ represents the specific growth rate, 𝜇𝑚𝑎𝑥 is the maximum specific growth rate, [s] is the substrate concentration, and 𝐾𝑠 is the saturation constant. the monod model assumes that the specific growth rate is limited by substrate availability and follows a hyperbolic relationship with the substrate concentration. b) logistic model the logistic model is an extension of the monod model that takes into account the inhibition effects of high substrate concentrations on microbial growth. it incorporates an additional term, 𝜇𝑚𝑎𝑥(1 − [𝑆]/𝐾𝐼) , to represent substrate inhibition. the logistic model is useful when dealing with fermentation processes where high substrate concentrations can negatively impact microbial growth and product formation. c) contois model the contois model is a kinetic model that considers the limitation of both substrate and product concentrations on microbial growth. it assumes that the specific growth rate is proportional to the substrate consumption rate and the square of the product concentration. the model equation is given by equation 6: 𝜇 = 𝜇𝑚𝑎𝑥𝑆 𝐾𝑠+[𝑆]+𝛼[𝑃] 2 (6) where 𝜇 represents the specific growth rate, μmax is the maximum specific growth rate, [s] is the substrate concentration, [p] is the product concentration, 𝐾𝑠 is the saturation constant for substrate, and α is the inhibition constant for product. the contois model provides a more comprehensive representation of fermentation kinetics by considering the inhibitory effects of product accumulation. d) luedeking-piret model https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 95 the luedeking-piret model is a phenomenological model that describes the production rate of a desired product during fermentation. it assumes that the production rate is a function of both the growth-associated and nongrowth-associated components. the model equation is given by equation 7: 𝑃 = 𝛼𝜇 + 𝛽[𝑆] (7) where 𝑃 represents the product concentration, μ is the specific growth rate, [s] is the substrate concentration, and 𝛼 and 𝛽 are the luedeking-piret coefficients. the luedeking-piret model is useful for analyzing the relationship between microbial growth and product formation during fermentation. e) structured kinetic models structured kinetic models consider the intracellular processes and metabolic pathways of microorganisms during fermentation. these models describe the dynamic changes in cellular components, such as biomass, substrate, and product concentrations, and the corresponding fluxes. structured models are more complex and require additional parameters and data for their calibration, but they provide a more detailed understanding of the microbial fermentation process (ali et al., 2023; elmer & gaden, 2000). kinetic models for fermentation processes help elucidate the relationship between substrate consumption, product formation, and microbial growth (kresnowati et al., 2015). by fitting these models to experimental data using parameter estimation techniques, the kinetic parameters can be determined, enabling the prediction of product yields and the optimization of fermentation processes (brito & antunes, 2014; shatalov et al., 2013). however, it is important to consider the limitations of these models, such as the assumption of constant parameters and the simplifications made in describing complex biological processes, when applying them to specific fermentation systems. factors affecting reaction kinetics understanding the factors that affect reaction kinetics is crucial for optimizing reaction conditions, predicting reaction rates, and designing efficient chemical processes. some key factors that influence reaction kinetics are the concentration of reactants, temperature, catalysts, surface area, presence of inhibitors or catalyst poisons, pressure, solvent, reaction mechanism, activation energy and molecular orientation. the concentration of reactants plays a significant role in determining the rate of a chemical reaction. according to the collision theory, for a reaction to occur, reactant molecules must collide with sufficient energy and proper orientation. higher concentrations of reactants increase the frequency of collisions, leading to a higher reaction rate. temperature has a profound effect on reaction kinetics. increasing the temperature generally increases the reaction rate. this is because higher temperatures provide reactant molecules with more kinetic energy, resulting in more frequent and energetic collisions. additionally, higher temperatures can overcome activation energy barriers, allowing reactions to proceed more readily (sodiqovna, 2020). catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. they lower the activation energy required for the reaction to occur, thereby facilitating the formation of products. catalysts provide an alternative reaction pathway with a lower activation energy, allowing for faster reaction rates. in reactions involving solids or heterogeneous systems, the surface area of the reactants plays a vital role. increasing the surface area by breaking solids into smaller particles or using catalysts in finely divided form exposes a larger area for reactant molecules to come into contact. this enhances the frequency of collisions and increases the reaction rate (sodiqovna, 2020). https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 96 in gas-phase reactions, pressure can affect reaction kinetics. increasing the pressure increases the number of gas molecules per unit volume, which leads to more frequent collisions. higher pressure can increase the reaction rate by increasing the concentration of reactant molecules and their collision frequency. the specific reaction mechanism, including the sequence of elementary steps, intermediate species, and rate-determining steps, influences the overall reaction rate. understanding the reaction mechanism is crucial for designing appropriate kinetic models and optimizing reaction conditions. the choice of solvent can significantly impact reaction kinetics, particularly in liquid-phase reactions. the solvent can affect the stability of reactants, the solubility of reactants and products, and the mobility of molecules, all of which influence reaction rates. inhibitors are substances that decrease the rate of a reaction, while catalyst poisons are substances that deactivate catalysts. both inhibitors and catalyst poisons reduce the effectiveness of the reactants or catalysts, leading to a slower reaction rate for reactions involving multiple reactant molecules, the molecular orientation during collisions can affect reaction kinetics (abril-gonzález et al., 2023). in some cases, specific molecular orientations are required for effective collisions and reaction to occur. factors that influence molecular orientation include steric hindrance, molecular shape, and the presence of functional groups. activation energy is the minimum energy required for a reaction to occur. reactions with higher activation energies typically have slower reaction rates. lowering the activation energy through factors like temperature, catalysts, or the presence of suitable reactant molecules can significantly accelerate the reaction rate. understanding and manipulating these factors can help control and optimize reaction kinetics in various chemical processes. it allows for the design of efficient reactions, the development of suitable reaction conditions, and the prediction of reaction rates and yields. experimental techniques for kinetic parameter estimation experimental techniques for kinetic parameter estimation are essential for obtaining accurate and reliable information about the rate constants and parameters that govern chemical reaction kinetics. these techniques involve conducting experiments under controlled conditions and analyzing the resulting data to determine the kinetic parameters. some experimental techniques for kinetic parameter estimation are (shim et al., 2020; yu et al., 2021): a) method of initial rates: the method of initial rates is a widely used technique for estimating kinetic parameters. it involves conducting multiple reactions with different initial concentrations of reactants and measuring the reaction rates at the beginning of each reaction. by analyzing the data, such as plotting the initial rate versus the initial concentration, the rate constant or reaction order can be determined. b) integrated rate laws: integrated rate laws involve measuring the concentration of reactants or products at different time intervals during a reaction. by integrating the rate laws for different reaction orders or rate expressions, it is possible to obtain equations that relate the concentration of reactants or products to time. by fitting these equations to experimental data, the rate constant and reaction order can be estimated. c) differential analysis (onyelucheya et al., 2022): differential analysis involves measuring the change in concentration of reactants or products over time. by taking the derivative of the concentration-time data, the reaction rate can be determined. differential analysis is particularly useful for reactions with complex reaction mechanisms or when the reaction rates are not constant (abril-gonzález et al., 2023; salmi et al., 2020). d) temperature dependence: the temperature dependence of reaction rates can provide valuable information about the activation energy and temperature dependence of rate constants. by conducting reactions at different temperatures and analyzing the resulting data, the arrhenius equation can be used to estimate the activation energy and pre-exponential factor (adeoye et al., 2019; p. zhang & sutheerawattananonda, 2020). https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 97 e) in situ monitoring: in situ monitoring techniques involve measuring the concentration of reactants or products during the course of the reaction without the need for sample removal. techniques such as spectroscopy, chromatography, and mass spectrometry can be employed to monitor the reaction progress in real-time. in situ monitoring allows for continuous data acquisition and can provide insights into reaction kinetics and mechanisms. f) isotope labeling: isotope labeling techniques involve introducing isotopically labeled compounds into the reaction system. by monitoring the incorporation of isotopes into reaction products or following the isotopic exchange between reactants and products, information about reaction pathways, intermediate species, and rate constants can be obtained. g) design of experiments (doe): doe techniques involve systematically varying reaction conditions, such as temperature, concentration, and catalyst loading, to obtain a comprehensive set of data for kinetic parameter estimation. statistical analysis methods, such as response surface methodology and factorial designs, can be used to analyze the data and estimate the kinetic parameters. h) model fitting and simulation: mathematical modeling and simulation techniques can be employed to fit experimental data to kinetic models. software tools and optimization algorithms can assist in finding the best-fit parameters by minimizing the difference between the experimental data and model predictions. it is important to note that the choice of experimental technique depends on the specific reaction system, available resources, and the desired level of accuracy. often, a combination of different techniques is used to obtain a comprehensive understanding of reaction kinetics and estimate the kinetic parameters with greater confidence. optimization strategies for glucose production optimization strategies for glucose production involve maximizing the yield, conversion efficiency, and productivity of glucose production processes. these strategies aim to optimize various aspects of the process, such as reaction conditions, process parameters, and feedstock selection, to enhance the overall performance and economic viability (foust et al., 2020; sant et al., 2021). table 2 shows some commonly employed optimization strategies for glucose production. table 2: common optimization strategy and their significance (elalami et al., 2022; moreira et al., 2019) s/no optimization strategy description 1. reaction and process optimization optimizing the reaction conditions is crucial for maximizing glucose production. this includes optimizing parameters

the optimal reaction conditions can be determined 2. feedstock selection and pretreatment the choice of feedstock plays a significant role in glucose production. different feedstocks, such as agricultural residues, forest biomass, or algal biomass (andreeva et al., 2021), have different compositions and properties that affect their enzymatic or chemical conversion to glucose. optimizing feedstock selection involves considering factors such as availability, cost, composition, and ease of pretreatment to enhance glucose yield and minimize production costs. 3. pretreatment optimization pretreatment of feedstock is often necessary to enhance the accessibility of polysaccharides, such as cellulose or hemicellulose, to enzymatic or acid hydrolysis. optimization of pretreatment conditions, such as temperature, https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 98 pressure, residence time, and the use of specific pretreatment agents, can significantly improve the efficiency of glucose release from feedstock. 4. enzyme and catalyst optimization when enzymatic or acid hydrolysis is employed for glucose production, optimizing the choice and concentration of enzymes or catalysts is essential. this includes selecting enzymes with high activity and specificity, optimizing their dosage, and considering the use of enzyme cocktails or synergistic combinations to improve glucose release and minimize enzyme costs. 5. process integration and scale-up optimizing the integration of different process steps and optimizing the scale-up of glucose production processes are critical for commercial viability. process integration involves streamlining the process steps, minimizing energy consumption, and optimizing process flows to maximize efficiency. scale-up optimization focuses on translating laboratory-scale processes to larger production scales while maintaining consistent and efficient glucose production. 6. reaction kinetics and modeling understanding the reaction kinetics and developing mathematical models can aid in the optimization of glucose production processes (yassien & jiman-fatani, 2023). kinetic modeling helps in predicting glucose yields, identifying ratelimiting steps, and optimizing reaction conditions. it allows for the exploration of different scenarios and the identification of optimal operating conditions. 7. techno-economic analysis performing techno-economic analysis is crucial for evaluating the feasibility and economic viability of glucose production processes (sant et al., 2021). this analysis involves assessing the capital and operating costs, calculating the glucose production costs, and considering factors such as feedstock costs, enzyme costs, equipment costs, and market demand. optimizing the process parameters to reduce production costs and improve overall process economics is a key aspect of optimization strategies. 8. continuous process development optimizing glucose production often involves transitioning from batch processes to continuous processes (halka et al., 2018). continuous processes offer advantages such as improved productivity, better control over reaction conditions, and reduced labor and equipment costs. optimizing the design and operation of continuous processes for glucose production can lead to higher yields, improved efficiency, and reduced operational complexities. process optimization techniques process optimization techniques play a crucial role in improving the efficiency, productivity, and overall performance of chemical processes. these techniques involve systematically analyzing and improving different aspects of the process to achieve desired objectives, such as maximizing yield, minimizing costs, reducing waste, and improving product quality. in the context of glucose production, process optimization techniques aim to enhance the efficiency of glucose production processes. here (table 3) are some commonly used process optimization techniques: https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 99 table 3: optimization techniques in common application (malakar et al., 2020) s/no optimization technique description 1. multi-objective optimization in some cases, process optimization requires balancing multiple conflicting objectives. multi-objective optimization techniques aim to find optimal solutions that satisfy multiple objectives simultaneously. these techniques involve defining the objectives, determining their relative importance, and using optimization algorithms to identify the optimal trade-offs and pareto optimal solutions 2. process integration process integration techniques focus on optimizing the interaction and integration of different process steps to maximize efficiency and minimize resource consumption. techniques such as heat integration, mass integration, and pinch analysis are used to identify opportunities for energy recovery, minimize utility usage, and improve overall process efficiency. 3. computational modeling and simulation computational modeling and simulation tools enable the virtual optimization of process parameters, equipment design, and operating conditions. by developing mathematical models based on fundamental principles and simulating various scenarios, process optimization can be performed in a cost-effective and timeefficient manner. modeling and simulation allow for the evaluation of different process configurations and the identification of optimal operating conditions without extensive experimental testing. 4. six sigma six sigma is a data-driven approach aimed at reducing process variability and improving process performance. it involves the use of statistical analysis and problem-solving methodologies, such as dmaic (define, measure, analyze, improve, control), to identify and eliminate defects or variations in the process. six sigma helps optimize process parameters, minimize process variability, and enhance process capability. 5. lean manufacturing lean manufacturing principles focus on eliminating waste and optimizing process flow to improve efficiency and reduce costs. techniques such as value stream mapping, 5s (sort, set in order, shine, standardize, sustain), and just-intime (jit) production are used to identify and eliminate non-value-added activities, streamline production processes, reduce inventory, and improve overall process efficiency. 6. response surface methodology (rsm) rsm (uchegbu et al., 2022) is a statistical technique used to optimize process parameters by constructing mathematical models that relate process variables to the desired responses. rsm involves conducting experiments based on a predefined design matrix and using regression analysis to fit a response surface model. the model is then analyzed to identify optimal operating conditions that maximize the desired response, such as glucose yield or productivity. 7. statistical process control (spc) spc involves monitoring and controlling process variables to ensure that the process operates within defined limits and remains stable over time. it uses statistical tools, such as control charts, to detect and address any process variations or deviations. by continuously monitoring the process, spc helps maintain consistent process performance and reduces the likelihood of quality issues or production failures. 8. design of experiments (doe) doe is a statistical approach used to systematically vary process parameters and evaluate their impact on process performance. by conducting experiments with different combinations of variables, doe helps identify the most influential https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 100 factors and their optimal levels. this enables the identification of optimal process conditions and provides valuable insights into the process parameter interactions. by employing these process optimization techniques, glucose production processes can be optimized to achieve higher yields, improved efficiency, reduced costs, and enhanced product quality. each technique offers a unique approach to systematically analyze and improve different aspects of the process, leading to more sustainable and economically viable glucose production. statistical design of experiments statistical design of experiments (doe) is a powerful and systematic approach used to plan, conduct, and analyze experiments in order to gain insights into process behavior, optimize process parameters, and improve overall process performance. doe involves the careful selection of experimental factors and levels, the design of an appropriate experimental layout, and the statistical analysis of the obtained data. this approach enables researchers to efficiently explore and understand the relationship between process variables and responses, leading to more informed decision-making and process optimization. key components and benefits of the statistical design of experiments includes resource efficiency, optimization and insights, statistical analysis, randomization and replication, response variables, factors and levels and experimental design. factors are variables that can potentially influence the process or affect the response of interest. these may include process parameters, input variables, or environmental conditions. levels represent the specific values or settings at which the factors are set during the experiment. by selecting appropriate factors and levels, researchers can investigate the effect of each factor on the process and identify optimal operating conditions. experimental design involves planning the layout of the experiment to efficiently and effectively collect data. various designs, such as full factorial design, fractional factorial design, central composite design, and taguchi design, are available, each with its own advantages and limitations. the choice of design depends on factors such as the number of factors, desired resolution, available resources, and the need to estimate interaction effects. a well-designed experiment ensures that all relevant factors are systematically varied and properly controlled. response variables are the outputs or outcomes of interest that reflect the process performance. these may include glucose yield, conversion efficiency, productivity, or other relevant parameters. by carefully selecting appropriate response variables, researchers can gain insights into the impact of the experimental factors on process performance and identify opportunities for improvement. randomization involves assigning experimental runs to random order to minimize the influence of unknown or uncontrollable factors. randomization ensures that any systematic effects or biases are evenly distributed among the experimental units. replication, on the other hand, involves repeating experimental runs to obtain multiple observations at each combination of factor levels. replication helps estimate experimental error and improve the precision and reliability of the results. once the data are collected, statistical analysis techniques are applied to determine the significance of factors, identify the most influential factors, and quantify their effects on the response variables. analysis of variance (anova) is commonly used to assess the significance of the factors and their interactions (yassien & jiman-fatani, 2023). regression analysis is also employed to develop mathematical models that describe the relationship between factors and responses, allowing for prediction and optimization. doe provides valuable insights into the process behavior and identifies optimal process settings. by analyzing the experimental data, researchers can identify significant factors, determine optimal factor settings, and understand the interactions between factors. these insights enable process optimization, facilitate decision-making, and guide subsequent experiments or process improvements. doe helps optimize the use of available resources by reducing the number of experimental runs needed to obtain https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 101 meaningful results. by strategically selecting factor levels and employing efficient experimental designs, researchers can achieve a high degree of information with a minimal number of experiments. this results in significant time and cost savings compared to a traditional one-factor-at-a-time approach. the statistical design of experiments is a powerful tool for understanding and optimizing glucose production processes. by systematically varying factors, selecting appropriate designs, and applying statistical analysis, researchers can identify optimal process conditions, uncover relationships between variables, and make informed decisions to improve glucose production efficiency, yield, and quality. response surface methodology response surface methodology (rsm) is a statistical and mathematical modeling technique used to optimize process parameters and understand the relationship between multiple variables and a response of interest. rsm provides a systematic approach to analyze and optimize complex processes by constructing a response surface model based on experimental data (riaukaite et al., 2019). this model enables researchers to predict and optimize the response within the experimental domain and identify the optimal factor settings for process improvement. some key components and benefits of rsm includes experimental design, response surface model, model fitting and analysis, optimization, sensitivity analysis, validation and verification, and robustness analysis. rsm typically involves a series of carefully planned experiments, often using a design matrix such as a central composite design (ccd) or box-behnken design (uchegbu et al., 2022). the experimental design includes a set of predetermined factor levels that represent the range of values for each factor. these experiments are conducted to obtain response data at different factor combinations to capture the curvature and interaction effects. a response surface model is constructed using regression analysis to fit a mathematical equation that describes the relationship between the response variable and the factors. the model can be a linear, quadratic, or higher-order polynomial equation, depending on the complexity of the process and the observed data (jamil & wang, 2016; uchegbu et al., 2022). the model captures the main effects of factors, interaction effects, and curvature effects, allowing for response prediction and optimization. statistical techniques such as regression analysis, analysis of variance (anova) (yassien & jiman-fatani, 2023), and model diagnostics are employed to fit the response surface model to the experimental data. the model's goodness-of-fit is assessed using statistical metrics such as r-squared, lack-of-fit test, and residual analysis. these analyses help evaluate the significance of factors, identify important variables, and assess the model's reliability. once the response surface model is developed and validated, optimization techniques are applied to identify the optimal factor settings that maximize the desired response. optimization methods such as response surface optimization, desirability function approach, or numerical optimization algorithms are employed to determine the factor levels that yield the highest response value (uchegbu et al., 2022). optimization enables process improvement by identifying the optimal operating conditions. rsm facilitates sensitivity analysis to assess the impact of factors on the response variable and identify critical process variables. sensitivity analysis helps researchers understand the relative importance of factors and prioritize their optimization efforts (muhammad et al., 2022). it also assists in understanding the interactions between factors and their effects on the response, guiding the selection of factors for further investigation (riaukaite et al., 2019). once the optimal factor settings are identified, it is essential to validate the response surface model and confirm its accuracy. additional experiments are conducted at the predicted optimal conditions to verify the model's predictions. this step helps ensure that the model is reliable and can be used for process optimization and decision-making. robustness analysis assesses the stability and robustness of the https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 102 optimized process conditions. it involves evaluating the sensitivity of the response to variations in factors or process parameters. robustness analysis helps identify the range of factors within which the process remains optimal, considering practical constraints and potential process variability. the benefits of response surface methodology include (aydar, 2018; lamidi et al., 2022): • optimization: rsm enables the identification of optimal process conditions that maximize the desired response, leading to improved process performance and efficiency. • efficiency: rsm allows researchers to obtain a significant amount of information with a relatively small number of experiments, saving time, resources, and costs compared to a full factorial design. • insights: rsm provides valuable insights into the relationships between process variables and the response of interest. it helps researchers understand the effects of factors, identify interactions, and gain a deeper understanding of the process behavior. • decision-making: the response surface model provides a quantitative basis for decision-making, allowing researchers to compare different scenarios, evaluate trade-offs, and make informed decisions to optimize the process. • process understanding: rsm helps researchers gain a deeper understanding of the process by quantifying the relationships between variables and the response. this understanding can guide further process improvement and provide a basis for future research. optimization of glucose production using rsm optimization of glucose production using rsm is a statistical and mathematical approach that involves designing experiments and analyzing the response of the system to different experimental conditions. rsm is commonly used to optimize process variables and find the optimal conditions that maximize the production of glucose from a given feedstock, such as sugarcane bagasse, rice husk, or sawdust. below is an outline of how rsm can be applied to optimize glucose production (lai et al., 2016): (1) selection of factors: the first step is to identify the key factors that influence glucose production from the chosen feedstock. these factors could include enzyme dosage, pretreatment conditions (temperature, time, ph), fermentation time, and any other relevant process variables. (2) experimental design: rsm typically uses a doe approach to plan a set of experiments that cover a range of factor levels. the experiments are strategically chosen to explore the factor space efficiently and minimize the number of experimental runs required. (3) response surface model: the experimental data obtained from the doe is used to build a response surface model. this model relates the glucose production (the response) to the different process variables (factors) and their interactions. commonly used models include polynomial equations, which allow for the estimation of glucose yield under various combinations of factor levels. (4) optimization: the response surface model is then used to find the optimal combination of factor levels that maximizes glucose production. optimization techniques such as gradient-based methods or numerical optimization algorithms can be employed to determine the optimal settings for the factors. (5) validation: after obtaining the predicted optimal conditions, validation experiments are performed to confirm the predicted glucose yield under the optimized conditions. this ensures that the response surface model accurately represents the actual system and provides reliable predictions. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 103 (6) sensitivity analysis: sensitivity analysis can be performed to identify the factors that have the most significant impact on glucose production. this analysis helps in understanding which factors should be given priority in process improvement efforts. (7) process scale-up: if the optimized conditions from the rsm are successful at the laboratory scale, further studies may be conducted to scale up the process to a pilot or industrial level. scale-up considerations may involve factors like reactor design, process integration, and economic viability. multi-objective optimization approaches multi-objective optimization approaches are optimization techniques designed to handle problems with multiple conflicting objectives (abushaker et al., 2022). unlike traditional single-objective optimization, which aims to find a single optimal solution, multi-objective optimization seeks to find a set of pareto-optimal solutions that represent trade-offs between different objectives. these approaches are particularly useful in decision-making scenarios where multiple criteria need to be considered simultaneously. pareto optimality is a central concept in multi-objective optimization. a solution is considered pareto optimal if no other solution can improve one objective without deteriorating at least one other objective. the set of all pareto-optimal solutions is known as the pareto front or pareto set. each solution on the pareto front represents a different trade-off between the conflicting objectives, providing decision-makers with a range of options to choose from (kumar et al., 2022). several algorithms have been developed to solve multi-objective optimization problems (patane et al., 2019). these algorithms can be broadly categorized into evolutionary algorithms (e.g., genetic algorithms, particle swarm optimization), swarm intelligence algorithms, mathematical programming-based approaches (e.g., linear programming, nonlinear programming), and decomposition-based methods (e.g., weighted sum, εconstraint). these algorithms differ in their search strategies, exploration-exploitation balance, and handling of constraints, but they all aim to identify diverse and high-quality solutions on the pareto front (briones-baez et al., 2022; el moutaouakil et al., 2023). results and discussion techno-economic analysis of glucose production techno-economic analysis (tea) is a comprehensive evaluation method used to assess the feasibility and economic viability of a particular process or technology (das et al., 2022). in the context of glucose production, tea plays a crucial role in analyzing the costs, profitability, and overall economic performance of different production methods. it provides insights into the financial aspects of glucose production and helps decisionmakers evaluate the economic feasibility of implementing specific production processes. tea involves a detailed cost analysis that examines the various cost components associated with glucose production. these costs can include raw materials, equipment and infrastructure, labor, energy consumption, utilities, maintenance, waste treatment, and other operational expenses (jarunglumlert & prommuak, 2021). by quantifying and analyzing these costs, tea helps identify the major cost drivers and evaluate the overall cost structure of the production process. in addition to cost analysis, tea also considers revenue generation potential. it examines the market demand for glucose and estimates the potential sales volume and pricing (muhammad et al., 2022). market factors, such as supply and demand dynamics, competition, and pricing trends, are taken into account. by estimating the revenue generated from glucose sales, tea provides insights into the profitability and financial viability of the production process. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 104 tea includes sensitivity analysis to assess the impact of uncertain parameters and variables on the economic performance of glucose production. this analysis explores how changes in factors such as raw material prices, energy costs, labor rates, and market conditions affect the profitability and overall economic feasibility of the process (barba et al., 2022). sensitivity analysis helps identify critical factors and assess the robustness of the project's financial performance under different scenarios. cash flow analysis is a fundamental part of tea, focusing on the inflows and outflows of cash associated with glucose production. it considers the timing of costs and revenues over the project's lifespan to determine the project's cash flow profile (kuo & yu, 2020). cash flow analysis allows for the evaluation of the project's financial viability, profitability, and return on investment. it helps assess the project's ability to generate positive cash flow and recover the initial investment in a reasonable timeframe. tea provides an evaluation of the required capital investment for establishing glucose production facilities. it assesses the capital expenditure (capex) involved in purchasing equipment, constructing infrastructure, and setting up the necessary production processes. this analysis helps determine the investment requirements, payback period, and return on investment (roi) of the project (brandt et al., 2018). tea incorporates risk assessment and mitigation strategies to evaluate the potential risks and uncertainties associated with glucose production. it considers factors such as market volatility, regulatory changes, technological risks, and project-specific risks. by identifying and assessing these risks, tea assists in developing risk management strategies and evaluating the project's resilience against potential challenges (barba et al., 2022; muhammad et al., 2022). the primary goal of tea is to provide decision-makers with comprehensive information and insights to support informed decision-making (brandt et al., 2018). by quantifying the costs, revenues, and financial performance of glucose production, tea enables decision-makers to assess the economic feasibility of different production methods, compare alternative technologies, and identify areas for process optimization and cost reduction. in summary, techno-economic analysis of glucose production plays a vital role in evaluating the financial viability, profitability, and economic feasibility of different production processes. it helps assess the costs, revenues, cash flow, and investment requirements, providing decision-makers with the necessary information to make informed choices and optimize the economic performance of glucose production (ou et al., 2020; sant et al., 2021). cost analysis of feedstock acquisition cost analysis of feedstock acquisition is a crucial aspect of assessing the economic feasibility of glucose production (kuo & yu, 2020). feedstock, which refers to the raw materials used in the production process, typically represents a significant portion of the overall production costs. analyzing the costs associated with acquiring feedstock provides valuable insights into the financial implications of different sourcing strategies and helps decision-makers optimize the cost-effectiveness of glucose production. the cost analysis begins by examining the pricing of various feedstock options. different feedstock sources, such as agricultural residues, forest biomass, algal biomass, or food waste, may have varying cost structures (codato-zumpano et al., 2023). factors influencing feedstock pricing include availability, seasonal variations, demand-supply dynamics, transportation costs, quality considerations, and market competition. by assessing the prices of potential feedstock sources, the cost analysis enables the comparison of different options and their impact on overall production costs. apart from pricing, the quantity and quality of feedstock significantly influence the overall cost of acquisition. analyzing the required feedstock quantities and their availability helps estimate the scale of feedstock acquisition operations. this analysis considers factors such as feedstock yield, moisture content, impurities, and variability in feedstock characteristics (foust et al., 2020). understanding these factors enables decision-makers to assess the cost implications associated with sourcing, handling, and processing feedstock. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 105 the cost analysis also involves evaluating different sourcing strategies for feedstock acquisition. this includes assessing the feasibility and cost-effectiveness of sourcing feedstock locally or from external suppliers. local sourcing may offer advantages such as reduced transportation costs, access to abundant resources, and potential synergies with other industries (brandt et al., 2018). on the other hand, external sourcing may provide access to specialized feedstock varieties, larger quantities, or cost advantages due to economies of scale. evaluating the associated costs and benefits of different sourcing strategies helps determine the optimal approach for feedstock acquisition. feedstock acquisition involves various costs throughout the supply chain, from harvesting or collection to transportation and storage. the cost analysis considers factors such as collection methods, equipment requirements, logistics, transportation distances, storage facilities, and associated operational expenses. quantifying and analyzing these costs enables decision-makers to identify cost-saving opportunities, optimize supply chain efficiency, and minimize overall feedstock acquisition expenses (cheng et al., 2019). cost analysis of feedstock acquisition includes assessing and mitigating potential risks that may affect the availability and cost of feedstock. risks can include crop failures, weather-related events, market volatility, regulatory changes, or geopolitical factors. evaluating these risks helps decision-makers develop contingency plans, diversify feedstock sources, and ensure a stable supply of feedstock at reasonable costs. in addition to cost analysis, it is essential to consider sustainability aspects related to feedstock acquisition (muhammad et al., 2022). this involves evaluating the environmental impact of different feedstock sources, assessing their renewable or nonrenewable nature, and considering their alignment with sustainable development goals (cheng et al., 2019). while cost optimization is crucial, sustainability considerations can guide decision-making towards more environmentally friendly and socially responsible feedstock acquisition practices. the cost analysis of feedstock acquisition provides decision-makers with valuable information and insights to support informed decisionmaking. it helps assess the financial implications of different feedstock options, evaluate the cost-effectiveness of sourcing strategies, and optimize the overall feedstock acquisition process (zhang et al., 2020). the analysis assists in identifying opportunities for cost reduction, enhancing supply chain efficiency, and ensuring a reliable and cost-efficient feedstock supply (cheng et al., 2019). life cycle assessment of glucose production life cycle assessment (lca) is a systematic methodology used to evaluate the environmental impacts associated with the entire life cycle of a product or process, including raw material extraction, production, use, and disposal (kiš et al., 2019; osman et al., 2021). applying lca to glucose production allows for a comprehensive analysis of the environmental footprint and sustainability performance of different production methods. the lca of glucose production considers the entire life cycle, encompassing various stages such as feedstock acquisition, preprocessing, enzymatic or acid hydrolysis, fermentation, downstream processing, and final product distribution (ng et al., 2022). it also includes the energy consumption, emissions, and waste generated at each stage. by considering the full life cycle, lca provides a holistic perspective on the environmental impacts associated with glucose production. lca evaluates a range of environmental impact categories, including climate change, resource depletion, acidification, eutrophication, ozone depletion, and human toxicity (ryan & yaseneva, 2021). these impact categories capture different aspects of environmental sustainability and allow for a comprehensive assessment of the potential environmental burdens associated with glucose production. assessing multiple impact categories provides a more robust and balanced understanding of the environmental performance of different production methods. lca requires gathering data on various inputs and outputs throughout the life cycle stages of glucose production (osman et al., 2021). this includes https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 106 information on energy consumption, raw material extraction, water usage, emissions to air, water, and soil, waste generation, and transportation (jarunglumlert & prommuak, 2021). data can be obtained from literature, industry databases, process simulations, and direct measurements. accurate and reliable data collection is crucial for ensuring the accuracy and reliability of the lca results (kiš et al., 2019). defining the system boundaries is an important aspect of lca. it involves determining which processes and activities are included in the analysis and which are excluded. for glucose production, system boundaries can be set to include the entire production chain, from feedstock acquisition to the production of glucose, or focus on specific stages of the process (ryan & yaseneva, 2021). clearly defining the system boundaries ensures consistency and comparability among different lca studies and facilitates meaningful interpretation of the results (ng et al., 2022). during the impact assessment phase of lca, the collected data on inputs and outputs are translated into environmental impact indicators. this involves the use of impact assessment methods and characterization models to quantify the potential impacts on the selected impact categories. different impact assessment methods, such as recipe, eco-indicator, or cml, can be employed to assess the environmental impacts associated with glucose production. the choice of impact assessment method should align with the specific goals and context of the study. the results of the lca are interpreted to identify hotspots, areas of high environmental impact, and improvement opportunities. decision-makers can use the lca results to guide sustainability-oriented decision-making, such as selecting production methods with lower environmental impacts, optimizing processes to reduce resource consumption and emissions, or identifying opportunities for recycling and waste reduction (astuti et al., 2018). lca results can also inform product labeling, eco-design, and eco-innovation strategies to promote more sustainable glucose production. lca promotes transparency and communication of the environmental performance of glucose production. the results of the lca can be communicated through environmental product declarations (epds), sustainability reports, or labeling schemes. transparently communicating the environmental impacts helps stakeholders, including consumers, policymakers, and industry professionals, make informed choices and encourages continuous improvement in sustainability performance (blanco et al., 2020). sustainability considerations sustainability considerations play a critical role in the assessment and improvement of glucose production processes (ebikade et al., 2018). as the world increasingly focuses on environmental conservation, resource efficiency, and social responsibility, it is essential to evaluate the sustainability aspects associated with glucose production. few of the key sustainability considerations in glucose production includes, resource efficiency, renewable feedstock, environmental impact mitigation, climate change mitigation, water management, social and economic impacts and lca. efficient use of resources is a fundamental aspect of sustainable glucose production (salim, gonzález-garcía, et al., 2019). this involves minimizing resource consumption, such as water, energy, and raw materials, throughout the production process. implementing technologies and practices that optimize resource efficiency can reduce environmental impacts, conserve natural resources, and lower production costs. strategies like process integration, waste heat recovery, and recycling can contribute to improved resource efficiency. the choice of feedstock for glucose production has significant implications for sustainability. utilizing renewable feedstock sources, such as agricultural residues, forest biomass, or algal biomass, helps reduce dependence on finite resources and minimizes the environmental footprint of the production process (codato-zumpano et al., 2023; selivanov et al., 2023). renewable feedstock sources also offer opportunities for circular economy practices by valorizing waste and byproducts from other industries. glucose production should aim to minimize its environmental impacts, such as greenhouse gas emissions, water https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 107 pollution, and land use change. adopting cleaner production technologies, implementing pollution control measures, and optimizing waste management practices can reduce the ecological footprint of the production process (akmalina, 2019; salim, gonzález-garcía, et al., 2019). additionally, monitoring and mitigating potential environmental risks associated with feedstock acquisition, such as deforestation or habitat destruction, is essential for ensuring the sustainability of glucose production. glucose production contributes to climate change through the release of greenhouse gases, particularly during the energy-intensive stages of the process. implementing energy-efficient technologies, utilizing renewable energy sources, and adopting carbon capture and storage techniques can help mitigate the carbon footprint of glucose production (blanco et al., 2020). by reducing greenhouse gas emissions, the industry can contribute to global efforts to combat climate change and achieve sustainability targets. water is a valuable resource, and its sustainable management is crucial in glucose production. adopting water-efficient practices, such as recycling and reusing water within the production process, can help minimize water consumption. implementing wastewater treatment and management systems ensures the responsible discharge of treated water to minimize water pollution. additionally, considering water availability and prioritizing water-stressed regions for glucose production can help mitigate the potential strain on local water resources. sustainability considerations encompass not only environmental aspects but also social and economic dimensions (lips, 2021). it is essential to assess the social and economic impacts of glucose production on local communities, including employment opportunities, livelihoods, and community well-being. engaging with stakeholders, ensuring fair labor practices, and supporting local development initiatives contribute to the overall sustainability of glucose production and foster positive social outcomes. as discussed previously, conducting an lca provides a comprehensive evaluation of the environmental impacts associated with glucose production. lca allows for the quantification and analysis of energy consumption, emissions, waste generation, and resource depletion throughout the entire life cycle of glucose production (blanco et al., 2020). the results of lca can guide decision-making, identify improvement opportunities, and support the adoption of more sustainable practices. by integrating sustainability considerations into glucose production processes, stakeholders can work towards achieving a balance between environmental protection, social responsibility, and economic viability. through continuous improvement, innovation, and collaboration, the industry can contribute to a more sustainable future. case studies and industrial applications case studies and industrial applications provide valuable insights into the practical implementation of glucose production processes, highlighting their technical feasibility, economic viability, and sustainability performance. by examining real-world examples, researchers, industry professionals, and policymakers can gain a better understanding of the challenges, successes, and best practices associated with glucose production. case studies and industrial applications showcase the application of new technologies and innovations in glucose production. they provide examples of how advancements in enzymatic hydrolysis, acid hydrolysis, fermentation, and downstream processing have improved process efficiency, yield, and product quality. by studying these technological advancements, researchers and industry professionals can identify opportunities for process optimization, cost reduction, and environmental impact mitigation (yassien & jiman-fatani, 2023). case studies offer valuable insights into the optimization of glucose production processes. they demonstrate how various parameters, such as feedstock composition, enzyme dosage, reaction conditions, and fermentation strategies, can be adjusted to maximize glucose yield, minimize energy consumption, and reduce production costs (singh et al., 2021; yassien & jiman-fatani, 2023). analyzing successful process optimization strategies can guide https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 108 researchers and industry professionals in developing more efficient and sustainable glucose production methods. industrial applications of glucose production provide examples of scaling up laboratory-scale processes to commercial production (singh et al., 2021). case studies highlight the challenges faced during scale-up, such as process robustness, equipment selection, and integration of different process stages. they also shed light on the economic considerations, market demand, and regulatory requirements associated with commercializing glucose production. understanding these aspects is crucial for effectively transitioning from research to largescale implementation. case studies and industrial applications explore different feedstock sources and their suitability for glucose production (kuo & yu, 2020). they examine the selection criteria, availability, cost-effectiveness, and sustainability implications of using various feedstock options, such as agricultural residues, forest biomass, algal biomass, or food waste (andreeva et al., 2021; c. zhang et al., 2020). these studies provide insights into the challenges and opportunities associated with feedstock acquisition, preprocessing, and handling, enabling decision-makers to make informed choices regarding feedstock sourcing. glucose production is often integrated into biorefinery concepts, where multiple value-added products are derived from the same feedstock. case studies and industrial applications demonstrate the integration of glucose production with other biorefinery processes, such as bioethanol production, bioplastics manufacturing, or biochemical production (foust et al., 2020). these examples highlight the synergies, waste valorization, and economic benefits of adopting a holistic approach to biomass utilization. case studies provide insights into the sustainability performance of glucose production processes. they showcase the application of sustainability assessment tools, such as lca, carbon footprint analysis, or water footprint analysis, to evaluate the environmental impacts and resource efficiency of glucose production. by studying these assessments, researchers and industry professionals can identify opportunities for improving the sustainability profile of glucose production and aligning it with sustainability goals. case studies and industrial applications serve as a platform for knowledge sharing, collaboration, and cross-learning among researchers, industry professionals, and policymakers. they facilitate the exchange of experiences, challenges, and best practices, fostering innovation and continuous improvement in glucose production. through collaboration and shared learning, the industry can collectively address technological, economic, and sustainability challenges, accelerating the development and adoption of more efficient and sustainable glucose production processes. glucose production from corn starch glucose production from corn starch is a widely utilized process in the food and beverage industry (dusabe et al., 2023), as well as in various industrial applications. corn starch, derived from the endosperm of corn kernels, is a rich source of starch, which can be hydrolyzed to produce glucose. production steps includes corn starch extraction, starch slurry preparation, enzymatic hydrolysis, enzyme inactivation and filtration, purification and concentration, crystallization and final utilization (awulachew, 2020). the first step in glucose production from corn starch involves extracting starch from corn kernels. the corn kernels are typically ground and separated into various components, including germ, bran, and endosperm. the endosperm contains the highest concentration of starch. the extracted endosperm is then washed to remove impurities and processed to obtain a purified corn starch. to initiate the enzymatic hydrolysis process, the corn starch is mixed with water to form a starch slurry. the slurry is typically adjusted to a specific ph and temperature, which are optimal for the subsequent enzymatic hydrolysis reaction. enzymatic hydrolysis is the key step in converting corn starch into glucose (zhu & pan, 2022). specific enzymes, such as amylases, are added to the starch slurry. these enzymes break down the starch molecules into smaller fragments, including glucose molecules. the enzymatic https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 109 hydrolysis reaction is typically conducted at controlled temperature and ph conditions, along with appropriate reaction time, to ensure optimal enzyme activity and starch conversion (zhang et al., 2020). once the desired level of hydrolysis is achieved, the enzymatic activity is typically deactivated by adjusting the ph or temperature of the reaction mixture. the resulting mixture is then subjected to filtration or centrifugation to separate the glucose-rich solution from the undigested residues, such as insoluble fibers or protein impurities. the obtained glucose solution may undergo further purification steps to remove impurities, such as residual enzymes, colorants, or organic compounds. common purification techniques include filtration, ion exchange, activated carbon treatment, and membrane processes. the purified glucose solution is then concentrated through evaporation or membrane processes to increase the glucose concentration (flores et al., 2018). in some cases, glucose may be further processed through a crystallization step to produce glucose crystals or glucose syrup. crystallization involves controlled cooling and seeding of the concentrated glucose solution to induce the formation of glucose crystals. the resulting crystals can be separated, washed, and dried to obtain pure glucose. the produced glucose can be used as a sweetener in the food and beverage industry, replacing sucrose or highfructose corn syrup (kiš et al., 2019; riaukaite et al., 2019). it serves as an essential ingredient in various products, including confectionery, baked goods, beverages, and processed foods. additionally, glucose finds applications in pharmaceuticals, fermentation processes, and as a precursor for the production of other chemicals. glucose production from corn starch offers several advantages, including the abundance and availability of corn as a feedstock, scalability of the process, and versatile utilization of the glucose product. however, it is important to consider the sustainability aspects associated with corn cultivation, such as land use, water consumption, and environmental impacts (awulachew, 2020). efforts are being made to explore alternative feedstocks and sustainable production methods to ensure the long-term viability and environmental friendliness of glucose production. glucose production from cellulosic biomass glucose production from cellulosic biomass offers a promising avenue for sustainable biofuel and biochemical production (osman et al., 2021). cellulosic biomass, which includes sources such as agricultural residues, forest biomass, and dedicated energy crops, contains cellulose, hemicellulose, and lignin (selivanov et al., 2023). the process of converting cellulosic biomass into glucose involves several steps, as outlined below: (i) pretreatment (zhou et al., 2023): pretreatment is a crucial step in cellulosic biomass conversion. it aims to remove or modify the lignin and hemicellulose components, making the cellulose more accessible to enzymatic hydrolysis. various pretreatment methods, including physical, chemical, and biological processes, can be employed. common techniques include steam explosion, acid or alkaline hydrolysis, organosolv, and ammonia fiber expansion (afex) (jarunglumlert & prommuak, 2021). pretreatment conditions and severity are optimized to maximize cellulose accessibility while minimizing sugar degradation and inhibitor formation (malakar et al., 2020). (ii) enzymatic hydrolysis: enzymatic hydrolysis is the core step in converting cellulose to glucose. after pretreatment, the cellulose-rich material is treated with cellulase enzymes. cellulase enzymes break down cellulose into glucose by cleaving the cellulose chains into smaller sugar units. the enzymatic hydrolysis reaction is typically carried out at controlled temperature, ph, and enzyme dosage to optimize glucose yield. enzyme cocktails containing different types of cellulases are often used to improve hydrolysis efficiency (zhu & pan, 2022). https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 110 (iii) enzyme recycling and inhibitor management: during enzymatic hydrolysis, the enzymes can be partially deactivated or inhibited by the released sugars and by-products (turini et al., 2021). to enhance the efficiency and economics of the process, strategies such as enzyme recycling and the use of enzyme inhibitors can be implemented. enzyme recycling involves separating the enzymes from the hydrolysate and reusing them in subsequent hydrolysis batches. inhibitor management techniques, such as detoxification or conditioning of the hydrolysate, can minimize the negative impact of inhibitors on enzyme activity and glucose yield. (iv) fermentation (yassien & jiman-fatani, 2023): after enzymatic hydrolysis, the resulting glucose-rich hydrolysate can be subjected to fermentation to produce various biofuels and biochemicals. glucose can be fermented by microorganisms, such as yeast or bacteria, into ethanol, butanol, organic acids, or other valuable products. the fermentation process may require additional steps, such as microbial strain selection, optimization of fermentation conditions (temperature, ph, nutrient supplementation), and downstream processing for product recovery. (v) downstream processing: downstream processing involves the separation, purification, and recovery of the desired product from the fermentation broth. techniques such as filtration, centrifugation, distillation, chromatography, and membrane processes are employed to isolate and purify the target compound, such as glucose or the desired fermentation product. the purity and concentration of the final product depend on the intended application. glucose production from cellulosic biomass offers several advantages, including the utilization of abundant and renewable feedstock sources, reducing dependence on fossil fuels, and mitigating greenhouse gas emissions (shokrkar & ebrahimi, 2021). however, challenges remain in terms of improving the efficiency and costeffectiveness of the process, addressing inhibitory compounds generated during pretreatment, and developing robust and efficient enzyme systems. ongoing research and technological advancements are focused on optimizing the individual steps, exploring novel pretreatment methods, developing superior enzyme cocktails, and enhancing the overall process integration to make cellulosic glucose production economically viable and environmentally sustainable (jones et al., 2018). glucose production from food processing waste glucose production from food processing waste offers a valuable opportunity for sustainable utilization of organic byproducts generated in the food industry. food processing waste, such as fruit and vegetable peels, pomace, spent grains, and other residues, often contains significant amounts of carbohydrates, including starches and sugars, which can be converted into glucose (andreeva et al., 2021; lee et al., 2023). the process of glucose production from food processing waste typically involves the following steps: [1]. waste collection and preparation: food processing waste is collected from various sources, such as fruit and vegetable processing facilities, breweries, or grain mills. the waste is typically sorted, cleaned, and prepared by removing any non-organic contaminants or inedible parts. the waste may also undergo size reduction or grinding to increase the surface area and improve subsequent processing efficiency. [2]. enzymatic hydrolysis or acid hydrolysis: enzymatic hydrolysis or acid hydrolysis is employed to convert the complex carbohydrates present in the food processing waste into glucose. enzymatic hydrolysis involves the use of specific enzymes, such as amylases or cellulases, to break down starches or cellulose into glucose (uchegbu et al., 2022). acid hydrolysis utilizes dilute acid solutions, such as sulfuric acid or hydrochloric acid, to hydrolyze the carbohydrates into simpler sugars (adeoye et al., https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 111 2019). the choice of hydrolysis method depends on the composition of the waste and the specific carbohydrates targeted for conversion. [3]. hydrolysate treatment: after hydrolysis, the resulting hydrolysate contains a mixture of glucose, other sugars, and impurities. the hydrolysate is often subjected to purification steps to separate the glucose from unwanted components, such as residual enzymes, solids, or organic acids. common purification techniques include filtration, sedimentation, and adsorption processes. [4]. glucose concentration (flores et al., 2018): to increase the glucose concentration in the hydrolysate, concentration techniques such as evaporation, membrane processes (such as reverse osmosis), or crystallization can be employed. these methods remove water from the hydrolysate, resulting in a more concentrated glucose solution. [5]. purification and refinement: further purification and refinement steps may be required to obtain a high-purity glucose product. these steps can involve techniques such as chromatography, ion exchange, or activated carbon treatment to remove remaining impurities, colorants, or off-flavors. glucose production from food processing waste offers several benefits, including waste valorization, reduction of waste disposal and environmental impact, and the potential for cost savings (lee et al., 2023). by converting waste into a valuable product, the process contributes to a circular economy and sustainable resource management. however, it is essential to ensure the quality and safety of the glucose produced, adhering to relevant regulations and quality standards. additionally, the development of efficient and cost-effective processing technologies, as well as waste collection and logistics systems, is crucial for the widespread adoption of glucose production from food processing waste (dusabe et al., 2023). glucose production in biofuel and bioproduct industries glucose production plays a crucial role in the biofuel and bioproduct industries, serving as a key intermediate for the production of a wide range of biofuels and bioproducts (mendoza-meneses et al., 2021). glucose can be derived from various biomass sources, including agricultural residues, energy crops, food processing waste, and cellulosic biomass. glucose is a primary substrate for bioethanol production. through the process of fermentation, glucose is converted by yeast or other microorganisms into ethanol, which is a renewable and sustainable alternative to fossil fuel-based gasoline (ali et al., 2023). glucose can be derived from various feedstocks, such as corn, sugarcane, wheat, and cellulosic biomass, and used as the main carbohydrate source for ethanol fermentation. bioethanol has gained significant attention as a renewable fuel, contributing to reduced greenhouse gas emissions and energy security. glucose can also serve as a precursor for the production of biobutanol, an advanced biofuel with potential as a gasoline substitute (tsai et al., 2020). biobutanol is produced through a process called acetone-butanol-ethanol (abe) fermentation, where glucose is converted into butanol, acetone, and ethanol by solvent-producing bacteria (ibrahim et al., 2018; yang et al., 2023). glucose can also be used as a feedstock for the production of other biochemicals, such as organic acids, amino acids, biopolymers, and specialty chemicals, through microbial fermentation or chemical synthesis routes (osman et al., 2021). although glucose itself is not directly used for biodiesel production, it can contribute indirectly by serving as a substrate for microbial oil production. microorganisms such as algae or oleaginous yeasts can utilize glucose as a carbon source to accumulate lipids or oils (yang et al., 2023). these lipids can be extracted and converted into biodiesel through a process called transesterification. glucose, therefore, plays a critical role in providing the necessary carbon and energy source for microbial oil production. glucose is a valuable platform chemical for the synthesis of various chemicals and materials. it can be converted into a range of platform chemicals, https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 112 including lactic acid, succinic acid, glycerol, and 2,3-butanediol (yu et al., 2022). these platform chemicals serve as building blocks for the production of bioplastics, biopolymers, solvents, resins, and other high-value chemical products (inyang et al., 2022). glucose-based platform chemicals offer a sustainable and renewable alternative to their petrochemical counterparts. glucose can be chemically modified or transformed into various derivatives, expanding its utility in different industries. glucose derivatives, such as glucose esters, glucose ethers, and glucose fatty acid esters, find applications in food, pharmaceuticals, cosmetics, and other sectors (lee et al., 2023). these derivatives possess specific functionalities and properties that enhance their suitability for specific applications. the production of glucose in the biofuel and bioproduct industries involves various processes, including biomass feedstock preparation, enzymatic or acid hydrolysis, fermentation, and downstream processing (weiss et al., 2019). the optimization of these processes, along with advancements in biotechnology, enzymology, and process engineering, continues to improve the efficiency, cost-effectiveness, and sustainability of glucose production (bauer et al., 2022; singh et al., 2021). the utilization of glucose as a feedstock for biofuels and bioproducts not only reduces reliance on fossil fuels but also contributes to the development of a bio-based economy and a more sustainable future (osman et al., 2021). technological challenges in glucose production glucose production is a complex process that involves several technological challenges (das et al., 2022). overcoming these challenges is crucial for improving the efficiency, scalability, and cost-effectiveness of glucose production. one of the challenges lies in the diverse nature of feedstock sources for glucose production (bisht et al., 2019). different biomass sources, such as agricultural residues, energy crops, food processing waste, and cellulosic biomass, have varying compositions and properties. preprocessing the feedstock to remove impurities, optimize particle size, and enhance accessibility of the carbohydrates is a critical step. however, developing efficient and scalable preprocessing technologies that can handle different feedstocks remains a challenge (osman et al., 2021). pretreatment is essential to break down the complex structure of biomass and make carbohydrates more accessible for enzymatic or acid hydrolysis. achieving an optimal balance between efficient pretreatment and minimal formation of inhibitors or degradation products is a technological challenge (ansanay et al., 2021). similarly, enhancing the efficiency of enzymatic hydrolysis or acid hydrolysis to achieve high glucose yields while minimizing enzyme requirements or acid usage is a continual focus of research and development (ebikade et al., 2018). enzymes play a vital role in the hydrolysis of carbohydrates to glucose. however, the cost of enzymes can be a significant barrier to large-scale glucose production. developing robust and efficient enzyme systems that can work under a wide range of conditions, improving enzyme stability and longevity, and reducing enzyme costs through advances in enzyme engineering and bioprocessing are ongoing challenges (rocha et al., 2022). in the case of fermentation-based glucose production, selecting suitable microbial strains that can efficiently convert glucose into desired products, such as bioethanol or biochemicals, is crucial. improving fermentation efficiency, including higher product yields, faster fermentation rates, and better tolerance to inhibitors, remains a challenge (yassien & jiman-fatani, 2023). genetic engineering and strain optimization techniques are being explored to enhance microbial performance and address these challenges. integrating different process steps, optimizing their interaction, and achieving efficient process integration are essential for glucose production. scaling up the glucose production process from lab-scale to commercial scale poses additional challenges, such as maintaining consistent performance, ensuring cost-effectiveness, and addressing engineering and logistical considerations. glucose production generates various byproducts and waste streams that require proper management. treating and utilizing these waste streams in an environmentally sustainable manner is a https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 113 challenge (zhu & pan, 2022). developing efficient strategies for waste treatment, including recycling, valorization, or conversion into value-added products, is essential to minimize the environmental footprint of glucose production. accurate monitoring and control of various process parameters, such as temperature, ph, enzyme dosage, and fermentation conditions, are crucial for optimizing glucose production (tagougui et al., 2018). implementing advanced process monitoring techniques, real-time control systems, and automation technologies to ensure consistent and efficient production is a technological challenge (bisht et al., 2019; didyuk et al., 2021). glucose production must be economically viable to compete with traditional production methods (zhu & pan, 2022). techno-economic analysis, including factors such as capital and operational costs, feedstock availability, product yields, and market demand, must be considered. balancing the costs and benefits of different process parameters and optimizing the overall process economics remains a challenge. addressing these technological challenges requires interdisciplinary research and collaboration among scientists, engineers, and industry stakeholders. continued advancements in biotechnology, enzymology, process engineering, and automation are essential for overcoming these challenges and driving the development of efficient, sustainable, and economically viable glucose production technologies (bauer et al., 2022; tagougui et al., 2018). conclusion investigation and optimization of glucose production via multiple biochemical processes and sustainable feedstock sources has yielded substantial insights and possible opportunities. as a critical biomolecule and renewable energy source, glucose holds great promise for meeting the growing demands of a sustainable and environmentally conscious world. the research looked on the kinetics and efficiency of enzymatic hydrolysis, acid hydrolysis, and fermentation routes. researchers can create novel techniques to improve glucose synthesis and utilization by better understanding these mechanisms. the evaluation of various feedstock sources, such as agricultural residues, forest biomass, algal biomass, and food waste, has offered significant information for the selection of sustainable feedstock. industries can lessen their environmental impact and contribute to a circular bioeconomy by utilizing locally sourced materials. optimization tactics were critical in this study, providing useful insights into optimizing glucose production systems. statistical design of experiments and response surface approach have paved the way for more efficient and cost-effective manufacturing procedures. furthermore, the techno-economic analysis and life cycle assessments have highlighted the need of taking both environmental and economic factors into account when evaluating glucose production technologies. sustainability considerations are critical in the quest for a greener, more resilient future. this study's multidisciplinary approach, which combined biochemical insights with sustainability considerations, provided a comprehensive understanding of glucose production. it has bridged the gap between scientific breakthroughs and real-world applications, making the research relevant to both industries and politicians. as we progress toward a more sustainable bioeconomy, glucose production plays an important role in a variety of sectors, including food, energy, and bioproducts. the study's findings provide useful direction for researchers, industry, and governments in driving the adoption of more environmentally friendly and efficient glucose manufacturing processes. to summarize, the study not only increased our understanding of glucose production, but it also underlined the need of sustainable practices and optimization tactics in designing a more sustainable and prosperous future for humanity. we can usher in an era of sustainable glucose production by embracing renewable carbohydrates and innovative technology, paving the road for a greener and more peaceful coexistence with our planet. https://www.jescae.com/index.php/gssr/gssr global sustainability research global scientific research 114 declaration acknowledgment: none funding: no funding source to declare. competing interests: there is no competing interest. authors’ contributions: conceptualization: engr. dr. kiman silas, formal analysis: mr. thlama mainta mperiju, methodology: indianraj n and rezkallah chafika, writing –original draft: engr. dr. mohammed modu aji and abdulhalim musa abubakar, writing –review & editing: agus budianto, engr. dr. kiman silas and engr. dr. mohammed modu aji data availability: from the authors references abril-gonzález, m., vele-salto, a., & pinos-vélez, v.

(alam, 2010). according to the world bank (2020) in ease of doing business summary, philippines ranked 95th out of 190 economies worldwide; it shows that a significant improvement from its previous ranking of 124, indicated a positive global sustainability research global scientific research 90 development in terms of ease in doing business, particularly in starting a private industry and dealing with business permit along with other licenses. in other words, the digital era has revolutionized the process of government so much that it interacts with the citizens and business owners. in an attempt to help the government reduce the bureaucracy, save costs, and increase citizen engagement, the government should initiate various forms of electronic governance (e-governance) mechanism such as online services delivery platforms that can improve efficiency, effectiveness, transparency, accountability, and accessibility of public services. the philippine government prioritizes digital technology adoption because the nation rapidly develops and maintains high internet usage among its population. the philippine government has launched multiple initiatives for better digital service delivery such as the national broadband plan and the egov philippine program. future actions need successful direction through detailed evaluation of the present conditions of the said initiatives along with current challenges and potential prospects. this scoping review provides a synthesis of existing literatures to give an extensive knowledge of digital governance in the philippines, identify research gaps, and inform policy and practice. this scoping review comprehensively analyzes digital governance in the philippines, examining its benefits, challenges, ethical implications, and future trends. to achieve this, the researchers addressed the following review questions: rq#1: what are the key perceived impacts (benefits and challenges) of digital governance initiatives in the philippines? rq#2: how can digital governance in the philippines be enhanced to improve public service delivery and citizen engagement while addressing ethical and social implications? rq#3: what are the emerging trends in the field of digital governance in the philippines? methodology a) protocol: this scoping review was guided by a detailed research protocol developed beforehand. the authors confirm that this report accurately reflects the review process, ensuring transparency and precision. the review strictly adhered to the protocol, and any unforeseen changes to the original plan have been clearly documented. this rigorous approach ensures the reliability and integrity of the review findings. this scoping review was conducted according to the prisma-scr (preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews) (morgan lee, james gambiza, 2022) guidelines to ensure transparent and comprehensive reporting (tricco et al., 2018). global sustainability research global scientific research 91 b) search eligibility criteria: studies were published in english language between 2020 and 2025 focusing on digital governance initiatives in the philippines were included. gray literature, such as government reports, policy documents, and white papers from relevant organizations was also considered. this review used the "population, concept, and context" (pcc) framework to determine which studies to include and how to organize the overall analysis (see table 1) table 1: eligibility criteria criterion inclusion exclusion rationale population studies focusing on citizens, government officials, businesses, or other participants involved in or impacted by digital governance initiatives in the philippines studies focusing solely on technology adoption without explicitly addressing governance aspects to ensure the focus remains on the governance implications of digital technologies in the philippine context concept studies exploring key concepts of digital governance such as egovernment, online service delivery, citizen engagement, open data, digital inclusion, and cybersecurity studies focusing solely on technical aspects of ict without addressing governance dimensions to maintain a focus on the governance aspects of digital technologies context studies examining digital governance initiatives in the specific context of the philippines studies focusing on digital governance in other countries without specific reference to the philippines to establish applicability of the philippine situation and avoid generalizations from other settings language studies published in english language studies published in other languages to ensure accessibility and comprehensibility of research findings global

government publications geographical location studies focusing on digital governance initiatives at the national level or within specific regions or localities in the philippines studies with a broader geographical scope that do not provide specific insights into the philippine context to ensure relevance to the specific context of digital governance in the philippines database scopus, google scholar, researchgate, and relevant government websites (e.g., official gazette, department of information and communications technology website) databases or websites with limited relevance to digital governance or the philippines to ensure comprehensive coverage of relevant literature from reputable academic databases and official government sources areas of research public administration (egovernance or digital governance) social sciences business management engineering technology computer science studies that do not directly address any of the key areas of research related to digital governance in the philippines to ensure the review captures a broad range of perspectives and issues relevant to the research objectives global sustainability research global scientific research 93 c) search strategy: a comprehensive search strategy was developed to identify relevant studies (moradpour et al., 2025) on digital governance in the philippines. the search was conducted on january 30, 2025, across multiple electronic databases including scopus, research gate, and google scholar, to ensure a broad coverage of academic literature. in addition, relevant government websites, such as the official gazette of the philippines and the department of information and communications technology (dict) website were browsed for policy documents, reports, and other publications related to digital governance initiatives. the search utilized a variety of keywords and search terms in various combinations to capture different aspects of digital governance. these keywords included terms like "digital governance," "e-governance," "philippines," "egovernment," "public service delivery," "citizen engagement," "digital divide," "data privacy," and "cybersecurity." examples of search strings used in the databases include ("digital governance" or "egovernance") and ("philippines" or "filipino") and ("e-government" or "electronic government") and ("public service delivery" or "online services") and ("philippines"). the search was confined to research released between 2020 & 2025 in order to present the most recent and important studies, the said research must strictly be published in english to ensure accessibility and comprehensibility of research findings. to improve the overall comprehensiveness of the search, reference list checking and citation searching were conducted to identify additional relevant publications. this multi-faceted search strategy aimed to identify all relevant abstract of digital governance in the philippines for inclusion in the scoping review. d) data extraction the data extraction process is guided by the research objectives and the key chapters found in the literature. prior to the formal review, preliminary searches helped the researchers determine the structure for data extraction, focusing on three key areas: 1. data from the reviewed documents related to perceived impacts of digital governance: this included extracting information on the types of digital governance initiatives, the technologies used, the stakeholders involved, the reported benefits and challenges, and the overall impact on public service delivery and citizen engagement. 2. data from reviewed publications regarding strategies and recommendations for enhancing digital governance: this involved extracting information on recommendations for improving digital governance initiatives, addressing challenges, and promoting wider adoption of digital tools and platforms. global sustainability research global scientific research 94 3. data on ethical and social implications, emerging trends: this included extracting information on ethical considerations related to data confidentiality, security, and inclusion, as well as emerging trends like the service of ai as well as big data in government. all extracted data were double-checked by the researchers to ensure accuracy and consistency. the data were then organized and categorized into the relevant thematic clusters identified in the results section. the systematic data extraction process made certain that the review captured comprehensive and relevant information from the included studies. results a) search and selection results the final search was conducted on february 17, 2025. initially, a total of 51 records were obtained from the chosen databases and government websites. after applying filters for language, subject area, and time span, the number of records were reduced to 26. figure 1: selection of publication for review (prisma-scr flow diagram) global sustainability research global scientific research 95 titles and abstracts were then evaluated for applicability, and 5 records were removed as they were deemed irrelevant to the research questions. full texts were retrieved for the remaining 21 records, and another 8 were disapproved after a detailed assessment of their eligibility. this left a final sample of 13 studies included in the scoping review. this search and selection procedure is shown schematically in the prisma flow diagram (figure 1). b) documents ultimately included in the review the review yielded 8 articles, three reviews, and one documents from website meeting the objective and eligibility criteria (table 2). table 2: documents included in the review reference publication title (kiram et al., 2025) data governance and

(dacer et al., 2025) challenge/s: the research highlighted significant barriers to digital governance, primarily stemming from inadequate infrastructure such as unreliable internet connectivity, limited access to hardware, and software insufficiencies. institutional constraints, including procurement challenges and funding inadequacies further exacerbated these issues. participants emphasized the urgent need for government and organizational support to address these gaps, indicating that improvement in infrastructure is a foundational step toward effective digital governance. the participants identified resistance to change and low digital literacy among teachers and school leaders as critical barriers. the "people" aspect was underscored as the most challenging component of digital governance, with cultural resistance and skill deficits hindering progress. targeted professional development programs and initiatives fostering a positive mindset toward digital transformation were suggested as key strategies to overcome these barriers. 1.improve internet connectivity and access: collaborate with government agencies and private providers to establish reliable internet connections in schools. increase funding allocation: advocate for higher budgetary allocations to procure essential hardware and software necessary for digital governance. streamline procurement processes: simplify procurement policies to ensure timely acquisition of digital tools and resources. 2. enhance digital literacy: implement continuous training programs for teachers and school leaders to build their digital competencies. promote a growth mindset: conduct workshops and leadership seminars to encourage openness to digital transformation among resistant stakeholders. engage stakeholders in change management: foster a participatory approach to involve teachers, staff, and students in digital governance initiatives to reduce resistance and increase buy-in. 3. adopt gradual implementation: introduce digital tools incrementally, prioritizing areas that provide immediate impact while building capacity for broader implementation. leverage partnerships: strengthen collaborations with ngos, private organizations, and global sustainability research global scientific research 103 educational technology providers to access training and resources. utilize open and cost-effective resources: encourage the use of open-source platforms and low-cost digital solutions to address resource constraints. 4. enhance technical support systems: establish dedicated teams or helplines to assist schools with digital tool maintenance and troubleshooting. increase policy flexibility: advocate for policies that allow schools to recruit itskilled personnel and customize solutions based on their specific needs. strengthen government-school collaboration: develop joint action plans with government agencies to address challenges in digital governance and ensure sustained support. these recommendations aim to address the identified barriers, build on progress, and create a sustainable framework for advancing digital governance in the schools division office of camarines norte. (barrios & moreno, 2024) challenge/s: 1.barriers such as the digital divide, resistance to change, and security concerns have impacted the effectiveness of these tools. facilitators like strong leadership, external partnerships, by identifying specific barriers such as the digital divide and resistance to change, and detailing effective facilitators such as leadership and collaboration, the research provides practical insights for policymakers and practitioners. these findings can guide the development of more effective egovernment strategies and interventions emerging trends and future research priorities: the integration of emerging technologies such as artificial intelligence and blockchain in egovernment systems present new opportunities and challenges. research global sustainability research global scientific research 104 and targeted training has been critical in overcoming these challenges. benefit/s: findings indicate that e-government initiatives, including the e-services portal and open data portal, have significantly enhanced administrative efficiency, reduced processing times, and improved transparency into how these technologies can be leveraged to enhance public sector efficiency and transparency, while addressing potential risks, would be a valuable addition to the field. (indama a. c., 2023) benefit/s: the review found that e-government initiatives have the potential to improve public service delivery by enhancing access, quality, and citizen engagement. (indama & salain, 2023) challenge/s: there are still challenges that need to be addressed. for example, ensuring that citizens have access to these digital technologies, and that they are designed to be accessible and userfriendly, is crucial. additionally, concerns around data privacy and security need to be addressed to ensure citizens can trust and use these digital technologies confidently. (palma et al., 2023) challenge/s: one of the main challenges facing the implementation of e-government in the philippines is the lack of adequate infrastructure and connectivity in some areas, as technology continues to advance, the government must continue to invest in infrastructure, capacity-building, and stakeholder engagement to ensure the success of e-government initiatives. global sustainability research global scientific research 105 particularly in rural and remote areas. this hinders the access and adoption of e-government services, limiting the potential benefits to citizens in these areas. benefits: the implementation of egovernment in the philippines has made significant strides in recent years, although challenges remain. the government has recognized the potential of technology to enhance public service delivery, increase transparency and accountability, and promote citizen engagement. as a result, several initiatives have been launched, such as the e-procurement system, the integrated tax system, and the electronic business permit and licensing system. (abales et al., 2023) challenge/s: citizens actively engaged with egovernance through media, yet challenges persisted, such as citizens’ hesitance to embrace e-government due to limited online technology skills. governments should focus on improving digital infrastructure, promoting digital literacy, addressing security concerns, and engaging citizens in the design and implementation of egovernment initiatives. by doing so, e-government can become a powerful tool for efficient and inclusive governance in the digital age. (cabughawang et al., 2023) to make government actions more transparent and easier to verify, the researcher developed a prototype of a blockchain network global sustainability research global scientific research 106 that can run government tasks in a way everyone can see and check (de castro & de castro, 2022) challenges: the study implies that the lack of funds and absence of a website manager were identified as challenges in the establishment of websites in some local governments to sustain e-government initiatives and ensure their successful implementation, the local governments may consider the following: 1. provide budget for e-government by integrating it in the annual budgeting plan of the lgus for their projects to become sustainable, 2. create plantilla positions for ict personnel who will handle website services, computerization and other e-government systems and projects of lgus, 3. capacitate more employees to develop the skills needed to implement e-government, 4. embark both on in-house development and outsourcing of egovernment programs and applications, 5. remain participative and supportive to the projects of the national governments specifically on the use of ict in governance, 6. strengthen collaboration with other local governments, private sectors, and higher educational institutions in implementing egovernment related projects and activities, 7. benchmark with other lgus to adapt their best practices on egovernment. (treceñe, 2021) recommendations: the government should take part in enhancing women’s representation in the decision-making structures in the government by incorporating global sustainability research global scientific research 107 gender perspectives and encouraging women in the marginalized sector to participate in the policy development process with regards to ict. the government should also focus on strengthening digital inclusion, particularly to the marginalized sector in the community where access to egovernment services is difficult. it is also important to allocate an adequate budget to local levels particularly in public school systems on the implementation of digital literacy initiatives. (ona s. e., 2020) recommendations: enacting laws can provide the government with basic legal guideline for implementing digital governance across national agencies and even in local governments, moreover, a digital governance law can prescribe the basic elements of a digital governance strategy such as enabling policies, capacity building programs, and skills development as well as requiring interoperability among national agencies. (bajar, 2020) this study recommends that the government should explore later the idea of centralized egovernment management which will eventually provide a system of virtual checks. the government may form a committee or designate the newly organized department of information and technology (dict) to conduct systematic, comprehensive, and consistent reviews to ensure that public resources are used productively. global sustainability research global scientific research 108 discussion all findings and results of this scoping review represents valuable and comprehensive insights in the perceived impacts of digital governance initiatives in the philippines. the review highlights both significant challenges and the potential benefits. on the other hand, digital governance has the capacity to alter or revolutionize public service in the philippines by making government services more accessible, efficient, effective, and responsive to the citizens’ needs. studies have reported positive impacts in various areas including improved public service delivery. digital platforms can streamline processes, reduce red tape, and enhance the overall quality of public service delivery (barrios & moreno, 2024). online access to government data and transactions can promote transparency and accountability, making it easier for citizens to monitor or check the government performance and hold officials responsible (barrios & moreno, 2024). by enhancing citizen engagement, digital tools, and systems can facilitate greater citizen participation in government decision-making, enabling citizens to voice their opinions, provide feedback, and contribute to policy formulation (indama, 2023 and ona s. e., 2020). in order to fully realize the potential of digital governance in the philippines, the analysis highlights key obstacles that must be overcome. these challenges include ict infrastructure deficiencies; the lack of adequate ict infrastructure including unreliable and slow internet connectivity and limited access to digital devices poses a major barrier to digital inclusion and participation (dacer et al., 2025; palma et al., 2023; agcaoli, 2020). digital literacy and skills gap; the digital literacy and skills gap among filipino citizens, government employees, and even teachers hinder the effective adoption and utilization of digital technologies (kiram et al., 2025; dacer et al., 2025; abales et al., 2023). institutional and financial constraints, limited funding for e-governance projects, complex procurement processes, and lack of dedicated it government personnel can impede the implementation and sustainability of digital initiatives of the government (dacer et al., 2025; de castro & de castro, 2022). resistance to change and digital divide can slow down the development and progress of digital transformation in the government (ducer et al., 2025). the study also revealed some new emerging trends that could be integrated into designing a new digitization system in governance. this includes artificial intelligence (ai) to provide public services, to utilize ai and make public service delivery faster and easier (barrios & moreno, 2024). another modern approach of using blockchain networks in e-governance, is a technology that allows governments to record and manage information in an impenetrable and transparent way. instead of keeping all data in one central computer, data is spread across many computers (cabughawang et al., 2023). conclusion this scoping review provides valuable and comprehensive overview of digital governance in the philippines. while the potential benefits are significant, the challenges are equally substantial. in order to harness the development and transformative power of digital governance, policymakers and stakeholders need to address the global sustainability research global scientific research 109 digital divide, promote digital literacy, strengthen institutional capacity, and foster a cooperative and innovative culture. the findings of this review highlight the need for further research on the long-term impacts of digital governance initiatives, particularly on marginalized and vulnerable populations. it is also crucial to investigate the effectiveness of different strategies for enhancing digital governance and promoting digital inclusion. by addressing these challenges and investing in research and capacity building, the philippines can leverage digital technologies to establish a more responsive, effective, efficient, and inclusive government that meets the expectations of its people. declaration acknowledgment: n/a funding: n/a conflict of interest: the authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper. ethics approval/declaration: this study did not involve human or animal subjects, and thus, no ethical approval was required. the study protocol adhered to the guidelines established by the journal consent to participate: all of the authors listed above were involved in this study consent for publication: all the authors listed above have agreed to publish their work in global scientific research journals. data availability: data openly available in a public repository authors contribution: all the authors contributed meaningfully to the actualization of the work references abales, m.-a. j., dandoy, v. a., pipino, o. r., & sobradil, m.

financial accessibility; globalization; lcc hypothesis; g-7 region introduction the sustainability of natural assets of the g-7 countries is a notable and ongoing concern, given that all of the members, except canada, have environmental imbalances (global footprint network, 2019). as the g-7 countries contribute to more than 60% of the world's net global wealth through their extensive economic activity, global sustainability research global scientific research 2 it is obvious that emissions from fossil fuels, coal, and conventional cooking fuels are the major cause of pollution (alola et al., 2022a). while several g-20 and g-7 states continued to grow commercially during the last ten years, the serious threat that climate change possess to ecosystem integrity continues to be one of the most significant challenges (alola et al.,2022b; hossain et al.,2023). according to unep (2019), mitigation in pollutions below 25% and 55%, respectively, is necessary to meet the goal of global humidity level less than 2 °c and 1.5 °c by 2030. the worldwide average temperature has spiked by 0.4 to 0.8 degrees celsius over the past several decades, and by 2100, it could climb by 1.4 to 5.8 degrees celsius (danish et al. 2020). as the g7 contributes to 27.3% of global emission of carbon, they do, address enormous environmental difficulties. remarkably, the inquiry finds that the united states, germany, the united kingdom, and japan are the g7's biggest pollutants (zheng et al., 2019). the group-7 territory offered a major improvement to the management of the globe's climate and attempted to diminish the rate of climate change by putting different policies into place through public and commercial institutions (song et al.,2021). in light of this, this research intends to explore the consequences for load capacity factor (lcf) in the g-7 areas of gdp, financial accessibility (fa), artificial intelligence innovation (ai), globalization (gob), and urbanization (urba). g-7 was selected for several considerations. with a considerable 39% share of the global economic output and 10.981 billion tons of emissions of carbon dioxide, the nations of the g-7 possess a major influence on the global economy. nonetheless, figuring out what causes global warming is essential (dastgeer et al., 2023). as a result, the economies of these nations bear a considerable degree of responsibility for environmental degradation. in addition, environmental damage continues to remain a risk to the g-7 countries even with their progress toward a green economy (khan et al. 2020). for example, the group generated around 38% of the total world emissions between 1960 and 2014 (world bank 2017). thirdly, among the numerous elements that contribute to environmental contamination in the region, the ongoing advancements in the global value chain provide further grounds for concern (ibrahim & ajide, 2021; mithun et al.,2023; faruk et al.,2023). a more accurate environmental evaluation can be obtained by the lcf (siche et al., 2010). it reflects a country's ability or capacity to sustain its people following their contemporary lifestyles (xu et al., 2022). thus, an ecosystem is considered sustainable when its lcf is larger than one and unsustainable when it is less than one (pata et al., 2021). consequently, implementing consideration of the aforementioned rationale, this research will hold significant policy implications for decision-makers concerning sustainable development goals (sdgs). concerns addressing the possible negative effects on human development emerge as technological developments, particularly in artificial intelligence (ai), transform the community (qin et al., 2023). artificial intelligence (ai) is a general term for several kinds of devices and platforms that replicate human intelligence and perform activities without human intervention (sohail et al.,2018a; sohail et al.,2018b; saba & monkam, 2024). it is a powerful instrument for boosting efficiency, effectiveness, and creativity because of its possible advantages in areas like automation, data analysis, and decision-making (makridakis 2017). artificial intelligence-driven commercialization is projected to reach $3.9 trillion in 2022, up from $1.2 trillion in 2018, which marked a 70% growth from 2017 (richards et al., 2019). the g-7 countries actively made investments in ai technologies, enacting regulations, establishing institutes for research, and assisting startups because they acknowledge the potential of ai in industries like medical sector, farming, finance, and others (cyman et al. 2021; dukhi et al. 2021).understanding the interplay among all these factors in this particular environment is crucial for designing modern strategies that focus on capitalizing on the advantages of ai integrated progress in the g-7 countries. the widespread prevalence of globalization illustrates the interdependence of nations, with foreign direct investment and international commerce significantly influencing the economic dynamics (jahanger et al. 2022; ozturk and ullah 2022). numerous environmental consequences of globalization are visible on an interpersonal and global scale. technological innovation can develop as an outcome of globalization and lessens the ecological impact (akadiri et al., 2020). however, a key global sustainability research global scientific research 3 contributing element to inadequate green growth is the uncertainty underlying economic policy (khan et al., 2019). the gdp of the g-7 nations is expected to reach 60.1 trillion us dollars (usd) in 2021, accounting for 44.1% of the world's gdp (wb, 2022). out of all the g7 nations, the united states has the greatest gdp with a wide margin. in addition, the gdp of the united states rose almost continuously between 2000 and 2022, surpassing the gdps of the other six countries combined to reach an estimated 25 trillion dollars in 2022. before china, the united states had the greatest economy in the world. at over 4.2 trillion us dollars, japan's gdp was the second biggest among the g7 (dyvik, 2023). several studies have been done to figure out the factors that contribute to environmental pollution, and many of them point to economic expansion as an important variable in the degrading of the natural world (ozcan and ozturk 2019; schröder and storm 2020). according to bhattacharyya (2018), ahmed et al. (2020), shah et al. (2019), and wu et al. (2020), decreasing economic growth has lowered carbon emissions since 2012. this investigation provides numerous important contributions to the existing body of knowledge. first off, most of the research that is currently available to assess the effects of lcf has merely looked at one or two of the consequences of globalization, artificial intelligence innovation, or financial accessibility, neglecting to take all three into account. second, when assessing ecological damage, the lcf offers a more sophisticated approach than the ecological footprint (ef). due to this, we decided to employ the lcf as an endogenous variable. furthermore, there is a shortage of information in the literature about the applicability of the lcc hypothesis in developing countries, such as the g-7 nations. our work fills this grasp by exploring the lcc hypothesis' applicability to the g-7 countries, which makes it a special contribution to the field. this might be partially explained by the inconsistent findings of the earlier empirical research. third, even with the theoretical and empirical data supporting the idea that innovation in ai regulates the adverse effects of various toxins in the environment, these types of concerns are still relatively new, especially for developed countries such as the g-7. fourth, by endeavoring to investigate the tripartite effects of gob, fai, and ai on environmental quality, this research is also novel. lastly, we use a strong and contemporary econometric approach by using the most recent data available for longand short-term estimations from 1990 to 2019 and performing panel unit root tests based on firstand second-generation methods, quantile regression, cross-section dependence tests, and the ardl method. additionally, we used amg, ccemg, and dkse estimates to confirm their robustness. following is the structure of the relevant study sections: in part 2, there is a thorough representation of the literature comprising related investigation summarized extensively. the third portion covers the topics and methodology; the fourth subsection includes the outcomes and discussions; and the final part contains the conclusion and its policy proposal. literature review many empirical analyses have addressed at the consequences of globalization, financial accessibility, ai innovation, and economic development on the load capacity factor (lcf). the majority of research has concentrated on how urbanization, green energy use, and advances in technology affected environmental quality; however, numerous analyses have made use of the ardl framework. the link between financial globalization, financial advancement, economic growth, and lcf has been examined in other research; nonetheless, the quantile regression approach has attracted less attention in those investigations. the literature on ecological deterioration in the g-7 countries is still in the early stages and lacks comprehensive research. however, a few earlier studies have provided direction for the factors and research techniques chosen. a handful of such inquiries will be examined in this section. a rising income level will allow the expansion of the lcf, improve environmental quality, and maintain the lcf curve within the asean region (dai et al., 2024). lin and ullah (2024) performed an analysis in pakistan using the time-series data from 1970 to 2021 and an advanced dynamic global sustainability research global scientific research 4 autoregressive distributed lag (dardl) approach. they discovered that the lcf decreases by 0.027 % for each 1% boost in economic development. in the top nuclear power economies, growth in gdp has a detrimental impact on the lcf dynamics that drive ecological degradation (teng et al., 2024). using methodologies for second-generation panel data, sun et al. (2024) investigate the factors that impact the lcf in 17 apec countries. the results of this research imply that ecological health declines with economic growth. in their analysis of g7 and e7 countries between 1997 and 2018, khan et al. (2023) observed a link within economic growth and a decline in the lcf. according to multiple studies (huilan et al.,2024; ozcan et al.,2024; du et al.,2024; awosusi et al.,2022; pata and isik,2021; das and sethi,2023; ahmad et al.,2024), gdp growth has a detrimental influence on lcf and lowers the quality of biodiversity. but when solarin et al. (2021) employed the ardl approach for nigeria between 1977 and 2016, they discovered that although growth in the economy initially degrades the environment, it eventually improves it over time. however, jahanger et al. (2023) discovered that lcf is favorably influenced by gdp expansion in the top sdg countries. between 2007 and 2014, ameyaw and yao (2018) investigated that here was no evidence of causation between co2 emissions and gross fixed capital creation, based on the study. similar to this, nathaniel et al. (2020) investigated how growth in the economy affected the efp in civets territory by utilizing the amg estimator. they concluded that gdp growth isn't harmful to biodiversity. moreover, raihan et al. (2024a) also observed similar outcomes in india. on the other hand, onwe et al.(2024) revealed that economic development has varied consequences on environment condition in japan. digital technology and artificial intelligence are being utilized progressively to enhance strategies for lowering co2 emissions from human activity. a variety of industries, including co2 disposal, depend on machine learning models for improved productivity. because classical approaches are obscure and hard to understand, bankers continue to utilize them despite advances in artificial intelligence (ferdous et al.,2023; shiam et al.,2024a; arif et al.,2024). a variety of industries, including co2 disposal, depend on machine learning models for improved productivity (shiam et al.,2024b; rana et al.,2024). several investigations (like rahman et al.,2024; abir et al.,2024) expressed that the major effect of artificial intelligence (ai) technology on raising standards for sustainability and effective marketing, particularly machine learning (ml), deep learning (dl), and big data. ai encourages sophisticated, efficient, and environmentally friendly industrial structures (sohail et al.,2019) which have an influence on co2 emissions (yuan et al., 2016). shiam et al.(2023c) considered an examination in nordic region from 1990 to 2020 to analyze the association between ai innovation, urbanization, gdp, stock market capitalization and banking improvement. by incorporating the stirpat framework they concluded that advancement in ai has inverse association with ecological footprint in the selected area. similarly, ridwan et al.(2024b) performed an analysis in usa from 1990 to 2019 to check the implication of ai on natural health. they made use the ardl technique and illustrates that ai related technology can ensures ecosystem sustainability. in g-7 area ridwan et al.(2024c) conducted another research by using mmqr method to see how ai innovation affect the lcf. their result demonstrated that application of ai has advantageous consequences on the ecosystem level. additionally, akther et al.(2024) explored a study in usa by adopting the ardl bound test covering data from 1990 to 2019. they observed that private funds in ai has favorable link with lcf. furthermore, hossain et al.(2024) in nordic region also aligned with this findings. using a variety of econometric methods, an in-depth examination of the complex connection between globalization and its implications on ecosystems has been carried out extensively. utilizing a long-run time series dataset spanning from 1970 to 2021, wang et al. (2023) demonstrated that environmental deterioration is negatively and severely impacted by globalization in china. when hasseb et al. (2018) examined an insignificant but negative correlation between the two factors. usman et al. (2020) explore how environmental damage is caused by globalization within the framework of south africa's ekc and discovered that ecological damage is reduced as a result of gob. shahbaz et al. (2017) employed the ardl bounds test technique from 1970 to 2012 global sustainability research global scientific research 5 together with the bayer and hanck combined cointegration analysis. they discovered that china's co2 emissions are significantly lower as a result of globalization. in opposition to the findings of these inquiries, ulucak and erdogan, (2022) claimed that in the cases of 78 developing and oecd nations, the gob had a detrimental effect on environmental pollution. using an examination of the implications of globalization, gdp, and digitization, li et al. (2023) observed at how the next eleven countries boosted their lcf between 1990 and 2018. using the csardl approach, the long-term outcomes illustrate that reliance on globalization reduced lcf. wenlong et al. (2022) showed through the use of the qardl technique that gob leads to an acceleration of ecological excellence in the united states. additionally, several investigations have demonstrated that globalization has an encouraging effect on ecosystem damage (jahanger et al., 2022; sadiq and khan, 2022; sheraz et al., 2022; wen et al., 2021). the foundation of all other types of advancements and businesses is a robust financial expansion, all of which is required to generate revenue for the finance sector. on the other hand, it has been demonstrated that there is a statically uncertain association between ecological and financial expansion (sharif et al., 2024). scholars assume that an even more expanded financial sector might potentially enhance the standard of living for individuals globally. the number of financing possibilities that become accessible could grow as the banking sector develops larger (tamazian et al. 2009; tamazian & rao 2010). to investigate the effect of financial accessibility on co2 emissions from 1990 to 2019, raihan et al. (2024b) carried out research in the g-7 territory. the results of the panel ardl model indicate that financial accessibility (fa) worsens the environment and raises co2 emissions in the g-7 region. additionally, fa boosts assets and earnings by generating affordable financing, boosting diversification of risks, and promoting company stability that leads to job creation. this expansion in turn increases the consumption of power which causes to co2 emissions and degrades the environment (acheampong 2019; sadorsky 2010). boussaidi and hakimi (2024) suggest that policymakers must enhance the standards of their institutions to promote growth, avert the detrimental effects of accessibility in finances, and safeguard ecological diversity in the mena area. on the other hand, gao et al. (2024) evaluate the importance of financial accessibility in the context of environmental pollution for the e-7 nations. the results highlight the positive effects of financial inclusion on carbon emissions and the significance of this policy for the sustainability of the environment. in five south asian economies, islam (2022) discovered that because there is a direct link between financial development and co2 emissions but the latter does not diminish with the development of financial accessibility. the goal of people transferring from rural to urban locations is to have typical lives while working in industries that generate revenue (ruel et al., 2008). urbanization encourages the need for transport and manufacturing, increases the use of oil and gas, and enhances the environmental impact (efp) (ulucak and khan 2020). within the context of the lcc theory, fang et al. (2024) examine the impact of political risk, biomass utilization, and natural resources on the lcf in asean nations. the ardl estimator's output demonstrates how urbanization lessens lcf, and the lcc curve is verified in thailand. the ardl approach is used by raihan et al. (2023b) to do research in mexico using data spanning from 1971 to 2018. the findings show that urbanization lowers mexico's lcf, which reduces the quality of the environment. additionally, they advocate for mexican authorities to endorse an ecologically conscious socioeconomic strategy and promote sustainable urban growth. moreover, urbanization may boost residents' spending power, which will influence their desire for renewable energy sources and decrease efp (danish and wang 2019). lin and ullah (2024) observed that in pakistan, a one percent rise in urbanization improves the lcf by 0.029 %. the relationship between co2 emissions and urbanization in the brics economies was analyzed by zhu et al. (2018). according to their results, urbanization lowers emissions and enhances the quality of the natural world. furthermore, danish et al. (2020) agreed with the findings that urbanization enhances the standard of ecosystems in the brics area using the fmols and dols methodologies. multiple studies, including ali et al. (2017) within singapore, raggad (2018) in saudi arabia, and saidi and mbarek (2017) for 19 nations, corroborate the global sustainability research global scientific research 6 aforementioned conclusions. however, raihan et al.(2022a) and voumik and ridwan (2023) opposed this findings and concluded that population growth harms the biodiversity. in the end, our review of previous research has demonstrated that there aren't lots of works that particularly investigate the llc hypothesis for the g-7 nations while accounting for the consequences of globalization, financial accessibility, and ai advancement. although the llc hypothesis has been examined in developing nations by various studies, their analysis has been limited and has not considered the effects of other areas of the economy. given that the g-7 countries are a rapidly emerging territory with distinctive macroeconomic and environmental features, it is sense to test the llc hypothesis. moreover, improvements in ai might support sustainable behaviors, minimize problems with the environment, promote energy efficiency, and assist agriculture all of which in turn could decrease the danger of climate change. from the g-7 perspective, these features make artificial intelligence (ai) an entirely novel area for study. this strategy makes it possible to estimate panel data models efficiently, which enhances the methodological understanding in the field. by examining these procedures, the selected nations might be able to assess if utilizing innovations in technology, financial cooperation, and sustainable development might offer the possibility to improve its lcf and improved sustainability. therefore, filling in this gap in the literature might enhance our knowledge of how economic progress and environmental damage interplay in the group seven countries while having an enormous effect on the long-term sustainability of the region's policies. methodology data and variables this study sought to explore the intricate connections between gdp, urbanization, financial accessibility, artificial intelligence (ai), globalization, and lcf for the g-7 countries. by adopting sophisticated econometric techniques, the investigation intended to evaluate the lcf hypothesis and get an understanding of the intricate interactions that exist across these variables. lcf, the dependent variable in the study, was taken from the reliable global footprint network (gfn, 2022). the world development indicators (2022) provided the gdp, gdp squared, and urbanization data, while trustworthy resources such as our world in data, the global financial inclusion index, and the kof globalization index provided the information on artificial intelligence, financial accessibility, and globalization. to provide a thorough summary of all characteristics examined, including their definitions, sources, and units of measurement, table 1 is extremely crucial. the goal of this meticulous paperwork was to ensure the research's consistency and clarity, which would reinforce the approach's integrity and transparency. theoretical framework the lcf is a dependent variable that is employed to capture the relevant elements for ecosystem condition in the quickly growing g-7 areas. the lcf first came up in the literature by siche et al. (2010), and pata (2021) was the first to do empirical research on the factors that influence the lcf. the lcc theory is centered on the lcf indicator, which considers opportunities for ecological provision and manmade environmental pressures into account (pata et al., 2023). since the lcf includes both efp and biocapacity in the denominator, a greater lcf is suggestive of a healthier environment (pata and kartal, 2024). the lcf offers a more thorough analysis of the environment by contrasting ecological footprint and biological resources (dogan & pata, 2022; islam et al.,2024). to improve the understanding of the foregoing study, we have created the following equation (1) for lcc theory: 𝐿𝑜𝑎𝑑 𝐶𝑎𝑝𝑎𝑐𝑖𝑡𝑦 𝐹𝑎𝑐𝑡𝑜𝑟 = 𝑓(𝐺𝐷𝑃, 𝐺𝐷𝑃2, 𝐾𝑡) (1) global sustainability research global scientific research 7 in equation (1), the variables for economic growth are gdp and 𝐺𝐷𝑃2 , whereas the variable for other factors influencing the load capacity factor is 𝐾𝑡 . equation (2) seeks to provide an expanded view of the elements changing the lcf by including additional relevant variables such as globalization, urbanization, financial accessibility, innovation in ai, and economic growth. 𝐿𝐶𝐹 = 𝑓(𝐺𝐷𝑃, 𝐺𝐷𝑃2, 𝐴𝐼, 𝐹𝐴, 𝐺𝑂𝐵, 𝑈𝑅𝐵𝐴) (2) table 1. data and variables variables description logarithmic form unit of measurement source lcf load capacity factor llcf gha per person gfn gdp gross domestic product lgdp current us$ wdi gdp2 gross domestic product square lgdp2 current us$ wdi ai artificial intelligence innovation lai patent application in ai field our world in data fa financial accessibility lfa automated teller machines (atms) (per 100,000 adults) global financial inclusion gob globalization lgob globalization index kof globalization index urba urbanization lurba urban population (% of total population) wdi the load capacity factor (lcf), economic growth (gdp), artificial intelligence (ai) innovation, financial accessibility (fa), globalization (gob), and urbanization (urba) are the abbreviations used in equation (2). the economic explanation of this equation can be obtained by equation (3).

(2022) suggest that as a consequence of variables including reduced obstacles to trade, improved socioeconomic connectivity, the usage of csd in panel data econometrics is growing. the authors of this research utilize the pesaran's (2015) analysis for weakly exogenous csd in large panel data econometrics to find whether csd exists. 𝐶𝑆𝐷 = √ 2𝑇 𝑁(𝑁−1)𝑁 (∑ ∑ 𝐶𝑜𝑟𝑟𝑖,𝑡 ̂𝑁 𝑚=𝑖+1 𝑁−1 𝑖=1 )……………………… (5) panel unit root test to explore if stationarity existed in our panel data, our research investigated unit root test techniques from both the first and second generations. we used the im et al. (2003)-introduced ips test and the levin, lin, and chu (llc) test, which is a first-generation unit root examination invented by levin et al. (2002). in contrast, secondgeneration unit root assessments that account for slope fluctuation and csd include cips and cadf, which were developed by pesaran (2007). the cips test is the extension of the ips examination (polcyn et al.,2023). voumik and sultana (2022) claim that the unit-root series forms the basis for the theory. before estimating the parameter, the test also recommends doing a cointegration test when the variable reaches first-difference stationarity. the below formula can be applied to represent the ips test: ∆𝑦𝑖𝑡 = 𝛿𝑖 + 𝛼𝑖𝑡 + 𝛽𝑦𝑖𝑡−1 + 𝜌𝑖∆𝑦𝑖𝑡−1 + 휀𝑖𝑡…………………………… (6) the llc test statistics is given below: ∆yit = 𝛿𝑖yit−1 + ∑ dij∆yit−1 + xit ′ η ρi j=1 + μit ……………………….(7) here, 𝑋𝑖𝑡 ′ means the column vector of the independent variable and in regression 𝜂 indicates the vector of parameters. the cips unit root test is a modified version of the ips method that looks at unit roots in individual time series. within the academic community, cips is becoming increasingly popular because of its efficaciousness in handling csd and heterogeneity. this test equation takes the following form: 𝐶𝐼𝑃𝑆 = 1 𝑁 ∑ 𝑡𝑖 𝑁 𝑖=1 (𝑁, 𝑇)………………………………………. (8) the cadf method is adopted to gather the statistics required by cips. the following equation describes the cadf statistics. ∆𝑌𝑖𝑡 = 𝛽𝑖 + 𝜌𝑖𝑌𝑖,𝑡−1 + 𝜗𝑖�̅�𝑡−1 + ∑ 𝛾𝑖𝑗∆𝑌𝑖,𝑡−1 + 휀𝑖𝑡 𝑝 𝑗=1 .................... (9) global sustainability research global scientific research 9 where, �̅�𝑡−1 and ∆𝑌𝑖,𝑡−1 are average for lagged and first difference of each cross-sectional series. panel cointegration test according to anser et al. (2024), cointegration denotes a reliable, long-term link between the panel's variables. the pedroni (1999) panel cointegration assessment is employed to figure out if cointegration prevails, assuming panel heterogeneity. this approach was adopted in the study; in contrast to kao (1999), it permits the ar coefficients to vary between panels. two separate tests were developed by pedroni (1999, 2004). four statistical measures are applied in the initial test, which uses a within-dimension approach: panel v-statistics, panel rhostatistics, panel pp-statistics, and panel adf-statistics. the following analysis utilizes a between-dimension methodology using group rho-statistics, group pp-statistics, and group adf-statistics as its three statistical measures. it is carried out in this manner: 𝑠ℎ𝑖𝑡 = 𝜗0 + 𝜇𝑖𝑡 + 𝛿1𝑖𝑏𝑘𝑑𝑖𝑡 + 𝛽2𝑖𝑖𝑏𝑖𝑡 + 𝜌3𝑖𝑖ℎ𝑟𝑖𝑡 + 휀𝑖𝑡…………… (10) where, i=1... n for each firm in the panel and t=1,..., t denotes the time period. the estimated residuals reveal how far the long-run association deviates from expectations. panel ardl model using the panel ardl framework, pesaran et al. (1999) established the pooled mean group (pmg) technique. pesaran et al. (1999) propose that the inconsistency situation, common technological advances, or the development of institutions that each group encountered constitute a few explanations for the homogeneity in the long-term connection. additionally, by considering lag duration for both exogenous and endogenous variables, the ardl model (attiaoui and boufateh,2019). furthermore, this approach has the advantage of effectively managing autocorrelation, heteroscedasticity, and multicollinearity difficulties in models, as illustrated by wang et al. (2021). in this study, the shortand long-term effects of gdp development, artificial intelligence (ai) innovation, financial accessibility, globalization, and urbanization on lcf were investigated using the pmgardl model. the pmg estimator relies on the ardl model and assumes that the panel as a whole has the same long-run coefficients, whereas each group has unique short-term coefficients, intercepts, and error parameters. the ardl simulation, which is considered relevant in this context if it can be specified as an error correction model when the underlying variables are somewhat integrated (i (0) and i (1)), with the restriction that the dependent variable is limited to just i (1) (voumik et al.,2023b; ridwan, 2023). nevertheless, this method is not applicable when variables are integrated for order 2 removes endogeneity issues and provides reliable and effective estimators (pesaran et al.,1996, 2001). the long-term association models for pmg are presented below: ∆y1,it = ϑ1i + β1iy1,it−1 + ∑ β1ix1,it−1 + ∑ λ1ij∆y1,it−j + ∑ ∑ λlijδx1,it−j + ε1i,t k l=2 q−1 j=0 p−1 j=1 k l=2 (11) here, 𝑌𝑖 refers the dependent variable and 𝑋𝑖 are independent factors where l=1,2, 3,4. 휀𝑖𝑡 and δ are residual & first difference operator accordingly. we found the following long-term ardl simulation for lcf as the dependent variable: ∆𝐿𝐿𝐶𝐹𝑖𝑡 = 𝜗1𝑖 + 𝛽1𝑖𝐿𝐿𝐶𝐹𝑖,𝑡−1 + 𝛽2𝑖𝐿𝐺𝐷𝑃𝑖,𝑡−1 + 𝛽3𝑖𝐿𝐺𝐷𝑃𝑖,𝑡−1 2 + 𝛽4𝑖𝐿𝐴𝐼𝑖,𝑡−1 + 𝛽5𝑖𝐿𝐹𝐴𝑖,𝑡−1 + 𝛽6𝑖𝐿𝐺𝑂𝐵𝑖,𝑡−1 +𝛽7𝑖𝐿𝑈𝑅𝐵𝐴𝑖,𝑡−1 + ∑ 𝜆1𝑖∆𝐿𝐶𝐹𝑖,𝑡−𝑚 + ∑ 𝜆2𝑖∆𝐿𝐺𝐷𝑃𝑖,𝑡−𝑚 + 𝑝 𝑖=0 𝑞 𝑚=1 global sustainability research global scientific research 10 ∑ 𝜆3𝑖∆𝐿𝐺𝐷𝑃𝑖,𝑡−𝑚 2 + ∑ 𝜆4𝑖∆𝐿𝐴𝐼𝑖,𝑡−𝑚 + ∑ 𝜆5𝑖∆𝐿𝐹𝐴𝑖,𝑡−𝑚 + ∑ 𝜆6𝑖∆𝐿𝐺𝑂𝐵𝑖,𝑡−𝑚 + 𝑝 𝑖=0 𝑝 𝑖=0 𝑝 𝑖=0 𝑝 𝑖=0 ∑ 𝜆7𝑖∆𝐿𝑈𝑅𝐵𝐴𝑖,𝑡−𝑚 + 휀1𝑖,𝑡 𝑝 𝑖=0 (12) the ect and short-term correlations are examined using the engle and granger (1987) ecm model after longterm relationships have been established (voumik et al.,2023c). equation (14) utilizes the ardl estimate with error correction representation to explain the short-term link across the variables: δllcfit = ∑ α1im∆llcfi,t−m + ∑ α2im∆lgdpi,t−m + ∑ α3im∆𝐿𝐺𝐷𝑃𝑖,𝑡−𝑚 2 + ∑ α4im∆laii,t−m + p−1 i=0 p−1 i=0 p−1 i=0 q−1 m=1 ∑ α5im∆lfai,t−m + ∑ α6im∆lgobi,t−m + ∑ α7im∆lurbai,t−m + μ1iect1,it−1 + ε1i,t p−1 i=0 p−1 i=0 p−1 i=0 (13) quantile regression additionally, this research adopted quantile panel regression analysis for several reasons. quantile analysis delivers a major benefit over conventional regression approaches as it enables one to figure out regression conditional quantiles and forecast how specific points within the conditional distribution will develop (alharthi et al., 2021). the study employed the panel quantile regression model proposed by koenker and bassett (1978) as an illustration as it permits users to utilize the values of the explanatory factors to judge the change in the dependent variable and the conditional mean (masiero et al., 2015). this offers vital details on the links between variables in numerous situations or quantiles (kilinc-ata et al.,2024). academics from a wide range of subjects, such as environmental research (carfora et al., 2017), economics (shahzad et al., 2017), and clinical studies (olsen et al., 2017), are embracing qr widely due to its numerous advantages. the qr can be shown by the following equation q𝐿𝑅𝐶𝑌it (∂ |∅0, xit, μi) = ∅0 + μit + ∅1 ∂lgdpit + ∅2 ∂𝐿𝐺𝐷𝑃2 it + ∅3 ∂𝐿𝐴𝐼it + ∅4 ∂lfait + ∅5 ∂lgobit + ∅6 ∂lurbait++ εit …………… (14) here,(∂ |∅0, xit, μi) is the ∂ th conditional quantile. moreover, the notion ∂ and xit indicates the quantile measure and independent factors accordingly. robustness check this stage involves running the dkse, amg, and ccemg procedures to confirm the results' robustness. to obtain the values of explanatory variables, we implemented three distinct estimators to find the longrun hyperlink. the average values of the findings for the explanatory variable are used in addition to the residuals in the driscoll and kraay (1998) standard error. when there is cross-sectional reliance, driscoll-kraay standard errors are employed because they are heteroscedastic, autocorrelation consistent, as well as resistant to typical forms of cross-sectional and temporal dependency (hoechle, 2007). teal and eberhardt (2010) included the production function in their revised augmented mean group (amg) panel estimator. the primary advantage of this method is that it can aid in the correction of outcomes when panel heterogeneity and multifaceted error terms are present (nathaniel & iheonu, 2019). in conclusion, pesaran (2006) developed this estimate model to replace the ccemg estimator. this method generates reliable figures, allows time-varying unobserved factors with varying influences across panel members and robust against csd problem. this approach can handle both an infinite number of "weak" factors and a finite number of "strong" unobserved common elements (anshasy and katsaiti, 2014; addae et al.,2023). global sustainability research global scientific research 11 d-h casuality test causality tests are required to identify the relevant policy implications for managing the emergence of the lcf. a technique for evaluating causal linkages between the components was presented by granger (1969); however, it has drawbacks and cannot be applied when panel data has a csd problem. the cointegration connection suggests all factors are in a long-term equilibrium. thus, we use the pane causality test of dumitrescu et al. (2021) to examine their causative relationship. because it can determine both n > t and t > n samples, this strategy can be flexible and beneficial for getting precise outcomes throughout cd (ahmed and le, 2021). by comparing each of the n factors to a minimum of one causal link in the panel, this method evaluates the null hypothesis of noncausality in each instance. in particular, the alternative hypothesis claims that at least a causality might be discovered in the panel (hurtado et al., 2024). result and discussion table 1 illustrates the statistical outcome of several measures of normality, such as skewness, probability, kurtosis, and the jarque-bera test. the dataset covers the g-7 nations from 1990 to 2019 and contains 91 observations for each variable. using the following descriptive statistics, the seven variables (llcf, lgdp, lgdpsq, lai, lgob, lfa, and lurba) are characterized. table 2. summary statistics statistic llcf lgdp lgdp2 lai lfa lgob lurba mean

observations 91 91 91 91 91 91 91 all selected variables have positive means, except for llcf, as can be observed in the table. additionally, most of the variables' estimated standard deviations are quite small, suggesting that the data points are a little temporally changeable and concentrated around the mean. the data for each variable, including the mean, standard deviation, lowest and maximum values, and the number of observations, will be shown in the box below. other than lgob and llcf, which have a negative skew, the majority of the variables have a positive skew. furthermore, each variable in this research was verified to have a normal distribution using the jarque-bera normality test. given that it takes into account both skewness and any anomalous kurtosis, this test is suitable. the pesaran (2004) csd evaluation findings are displayed in table 03 below. the p-values presented above conclusively indicate that at 1% significance levels, all of the variables (llcf, lgdp, lgdpsq, lai, lfa, global sustainability research global scientific research 12 lgob, and lurba) have statistical significance. in our research, cross-sectional dependency is accepted as the alternate hypothesis of the cd test. this suggests that our data collection contains csd. table 3. results of csd test variables cd-statistics p-value llcf 5.84*** 0.000 lgdp 5.36*** 0.000 lgdp2

the variables are stationary. the outcomes of these unit root analyses are displayed in table 04. in this research, llc, and ips, first-generation unit root tests were utilized in conjunction with cips and cadf, second-generation tests. the variables lai, lfa, and lgob are the only variables that show stationary behavior at the first difference, based on the llc test findings. at the i(1) difference, the other variables likewise exhibit stationarity. at the 1% significance thresholds, each of these factors is significant. however, the findings of the ips test indicate that only lfa and lgob stay stable at their initial level all other variables (llcf, lgdp, lgdpsq, lai, and lurba) are similarly significant at the 1% significance level and are stationary at the first difference (i(1)). the stationarity characteristics of the variables were further investigated utilizing the cips and cadf tests to guarantee more dependable findings. by adding cross-sectional averages of lag values and initial differences, these tests extend the capabilities of first-generation tests. moreover, table 05 demonstrates that, with the exception of lai and lgob, all variables are stationary following the first difference based on the cips test. in contrast, the findings of the cadf test indicate that all other variables are stationary at the first difference i(1), except for the lai and lfa, which are stationary at their level form. the outcome of this investigation indicates that the components have undergone considerable cointegration, hence removing the possibility of a unit root issue. table 4. panel unit root test variables levin, lin &chu ips cips cadf decision i(0) i(1) i(0) i(1) i(0) i(1) i(0) i(1) llcf -2.496 -5.071*** -0.702 -3.754*** -0.629 -3.869*** -1.230 -3.651***

cointegration test findings, encompassing both withinand betweendimension investigation. there is no indication of cointegration because the p-values for the panel v-statistic and panel rho-statistic (0.5186 and 0.9987, respectively) are higher than the conventional significance threshold. nonetheless, the panel pp-statistic and panel adf-statistic p-values are less than the traditional significance criteria, indicating that the null hypothesis of no cointegration is rejected. cointegration appears to be present based on these figures. the group rho-statistic in the between-dimension analysis displays a very high p-value of 0.9381, suggesting that there is not enough evidence for cointegration in any of the panels. the group adfstatistic and the group pp-statistic, on the other hand, both reveal evidence of cointegration across the panels, with p-values of 0.000. consequently, all of the variables are cointegrated over the long run, based on pedroni's cointegration techniques. table 5. panel cointegration test alternative hypothesis: common ar coefs.

(2012) added that the main factor contributing to environmental deterioration in mena nations is gdp growth. however, acheampong et al. (2022) observed that australia's co2 emissions are not heavily impacted by fluctuations in gdp. in the short and long terms, there is an encouraging link between lgdp2 and lcf, with statistically significant coefficients. these results demonstrate that rising gdp has a beneficial long-term impact on the environmental conditions in the g-7 economies. the study shows that, in both cases, artificial intelligence (lai) and lcf have a substantial positive link. over the short and long terms, an extra one percent in lai causes an equivalent rise in lcf of 0.029% and 0.142%, respectively. these findings highlight the need for ai innovation to guarantee the global sustainability research global scientific research 14 g-7 region's ecological viability over time. in a similar vein, lfa and lcf have a positive correlation over the short and long terms, suggesting that having access to money can have a good environmental impact. with pvalues less than 0.05 in each scenario, these results are statistically significant. this might be because immediate environmental surveillance strengthens the utilization of resources, and the application of ai can boost energy conservation in numerous areas, including residential electricity usage, travel, and manufacturing.. moreover, novel technologies should be encouraged by policymakers to safeguard the environment and advance biodiversity (alavijeh et al.,2023). the table indicates that there is a negative correlation between globalization (lgob) and lcf in both the short and long term; however, the effect is statistically significant in the long term and negligible in the short term. this shows that while globalization promotes increased commerce and energy demand, it is not potentially good for biodiversity. the growing need for commodities and amenities across national borders made accessible by global commerce has led to a spike in greenhouse gas emissions due to globalization (kirikkaleli et al.,2023). study by shahbaz et al.(2018) in japan and sharif et al.(2022) in g-& area also discovered that globalization is harmful for the ecosystem. however, globalization aids in resolving this problem and enhancing the environment (adebayo et al., 2022). furthermore, khurshid et al. (2024) demonstrate that environmental sustainability is positively impacted by globalization. similarly, urbanization (lurba) has a negative connection with lcf in both shortand long-term assessments. over time, a 1% spike in lurba generates a small but statistically significant 0.044% drop in lcf at conventional levels. with a p-value above 0.05, the findings, however, are not significant in the short run. furthermore, a significant short-term reduction of 0.222% in lcf is linked to a 1% rise in lurba. one possible reason for this outcome can be the loss of forests and the destruction of natural environments for construction are common consequences of growth in urban areas, which decrease diversity and disturb ecology. this conclusion defies those of aye et al. (2017), who claimed that economic expansion tends to cut co2 emissions in low-growth regimes and spikes in high-development regimes. we used the quantile regression (qr) approach to explore the factors influencing the lcf in the g-7 economies. five quantile points the fifth, 25th, 50th, 75th, and 95th were chosen especially for this study's regression calculation. first, for all quantiles, there is a negative correlation between the variable lgdp and llcf. this finding suggests that in the chosen area, economic expansion had a positive impact on environmental standards. in the first and fifth quantiles, the coefficient is significant at the 1% significance thresholds; in the remaining quantiles, it is significant at the 5% significance level. these indicate that gdp might have a detrimental effect on the environment of g-7 region. second, across all quantiles, lgdp2 has an upward association with lcf which is statistically significant at different levels. the first quantile has the lowest coefficient value, while the second quantile has the greatest. this investigation has taken into account lai, the third important component impacting lcf. except for the fourth quantile, which is significant at the 5% level, the outcomes illustrated that the lai coefficients are positively related to lcf and statistically significant at the 1% level for all quantiles. interestingly, the second quantile has the most effect; at the 25th percentile, an additional 1% in ai corresponds to a 0.094% increase in lcf. this indicates that adoption of ai is beneficial for g-7 area. the findings show an upward trend between the lfa variable and lcf, which is significant at the 1% level for all quantiles. a 1% rise in lfa causes an llcf increase of 0.84% in the first quantile and 2.11% in the final quantile. stated differently, financial accessibility in the g-7 economies fosters circularity and improves ecological conditions. it is noteworthy that there is a considerable rise in impact intensity throughout the quantiles. likewise, there is a beneficial relationship between the dependent variable, llcf and the variable lgob. the intensity rises through the upper quantiles, reaching 11.18 in the fifth quantile, with the exception of the second quantile, where the coefficient value is 2.775. global sustainability research global scientific research 15

-0.222 0.4836 -0.934931 0.0561 finally, with a single instance of the last quantile, the coefficient values for the indicator lurba are negative for every quantile. the discoveries demonstrate statistical significance at the 1% level in the first, second, and fifth quantiles; however, the finding is not significant in the third and fourth quantiles. it is clear from observation that the final quantile has the biggest coefficient value (3.66). the outcome suggests that urbanization in the chosen area has greater adverse impacts on the natural landscape. a number of estimating techniques, including dkse, amg, and ccemg, were used to further examine the accuracy of quantile regression estimates and ardl findings. table 08 contains information on the dkse, amg, and ccemg results. the projected lgdp values for the three tests are, respectively, -0.123, -0.049, and -0.054. these results indicate that economic expansion advantages the environment quality in the g-7 countries. the dkse and ccemg estimators have a significant coefficient value at 1%, but the amg estimator has a significant coefficient value at the 5% level. the outcome is aligns with the panel ardl model and quantile regression conclusions. conversely, the lcf variable has a positive correlation with lgdp2, lai, and lfa. the lgdp2 coefficient values are significant at the 10% level in the amg test and identical at the 1% significance level in the dkse and ccemg tests. in particular, a boost of 1% in ai innovation drives lcf to go up by 0.0077%, 0.0466%, and 0.0129%, in that sequence. this suggests that the g-7 countries' ecosystems may be improved by implementing ai technology. these results align with inferences made from the panel ardl and qr estimations. on the other hand, the lcf variable reveals adverse associations for lgob and lurba, suggesting that growing urbanization and globalization are detrimental to biodiversity in the chosen places. at the 1% level in the dkse estimation, the 10% level in the amg estimation, and the 5% level in the ccemg estimation, lgob and lurba are both statistically significant. the lgob result contradicts the conclusions of the ardl model and only agrees with the qr results. in the meanwhile, the panel ardl and qr findings agree with the lurba result. thus qr and ardl model, which serve as the main estimated method in this work, are validated by the outcomes obtained. global sustainability research global scientific research 16 table 7. quantile regression approach (1) (2) (3) (4) (5) variables q0.05 q0.25 q0.50 q0.75 q0.95

assessment for the lcf of the g-7 economy are summarized in table 9. the null hypothesis, which claims that the factor under investigation does not consistently cause another variable, can be rejected if the p-value approaches significant values of 1%, 5%, or 10%. based on the research, the p-value of 0.0039 demonstrates that the effect of lgdp on llcf is statistically significant at the 1% level. as a result, the null hypothesis can be rejected, guiding us to the conclusion that there is only one way of causality from lgdp to llcf. conversely, as the p-value is higher than the expected values, there is not a significant correlation between llcf and lgdp. this result suggests a one-way connection and illustrates how ecological health in the g-7 countries can be affected by economic expansion. table 8. robustness check (1) (2) (3) variables dkse amg ccemg lgdp -0.123*** -0.049** -0.054*** (0.0090) (0.0264) (0.0813) lgdp2 0.021*** 0.068* 0.199*** (0.0102) (0.1210) (0.0531) lai

similar unidirectional link between llcf and lgdp2. furthermore, as we are unable to exclude the null hypothesis in this instance, the results indicate fluctuations in llcf have no effect on lgdp2. the lcf and lai, on the other hand, have a bidirectional hyperlink, evidenced by statistically significant p-values across all studies. furthermore, as the suggested p-values are greater than traditional levels, there prevails no association from lfa to llcf, lcf to lfa, lurba to llcf and llcf to lurba. nevertheless, there exists a substantial unidirectional causal connection between lgob and llcf as the p-value is 0.0148 and it is significant at 1% significance level. this outcome reveals that we can reject the null hypothesis and come to the conclusion that globalization degrade the ecosystem. conclusion this comprehensive study discusses the complex relationships among globalization, urbanization, financial accessibility, ai innovation, economic growth, and lcf in the g-7 territory between 1990 and 2019. the lcc hypothesis is used in this research to determine how such significant variables affect lcf dynamics. data stationarity was observed using both first and second-generation unit root examinations to guarantee accurate estimation and to establish that the dataset was free of unit root problems. the panel cointegration test was also utilized in the inquiry to clarify the heterogeneous coefficients and demonstrate long-term cointegration across the factors under consideration. the panel autoregressive distributive lag model (ardl) in conjunction with quantile regression techniques enables an expanded examination of the complicated interactions between the dependent and explanatory variables. the results underscore the vital role of urbanization, gdp, and globalization in the higher rates of environmental pollution in the g-7 region. however, the quality of the ecosystem benefits from financial accessibility and ai innovation. to guarantee the correctness of the analytical framework, rigorous steps including dkse, amg, and ccemg were implemented. the robustness of the quantile regression and panel ardl studies was confirmed by all these techniques. furthermore, dumitrescu and hurlin (d-h) causality tests were used to explore the causal links between each variable. the findings demonstrated a unidirectional causal association between llcf and lgdp, lai, and lgob. in addition, it was discovered that none of the three factors financial accessibility, urbanization, and load capacity factor drives the other. our investigation delivers fascinating insights into the complexities of changing lcf patterns in the g-7, which has major global sustainability research global scientific research 18 implications for stakeholders and decision-makers who are committed to promoting green policies and equitable growth in those nations. creating policies that support both environmental sustainability and financial advancement is crucial to addressing the g-7 region's u-shaped link between wealth and load capacity factor. to lessen the negative effects on environmental sustainability as wealth grows, stricter regulations on resource use and pollution must be implemented. early on in the economic growth process, environmental degradation may be successfully stopped by offering tax breaks and subsidies to encourage sustainable practices and green technologies. furthermore, funding programs for awareness and education might encourage long-term client behavior. the promotion of advanced clean technologies and renewable energy sources must be the focus of policy given the continuous rise in wealth (raihan et al.,2024e). this will ensure that increasing income levels have more detrimental effects on the environment. encouraging corporate responsibility and integrating sustainability metrics into financial reporting have the potential to significantly accelerate companies' transition to greener practices. the g-7 nations' cooperation and idea sharing can increase the effectiveness of these programs even further. the g-7 area may attain a healthy balance between environmental sustainability and economic growth through the implementation of a progressive and adaptable plan. the results draw attention to important policy implications for the g-7 countries that want to improve environmental sustainability. governments ought to give ai research and development top priority, concentrating on innovations that track, forecast, and lessen environmental effects. promoting public-private partnerships may hasten the utilization of ai solutions in sectors including transportation, energy, and agriculture, maximizing resource efficiency and cutting emissions. furthermore, financial institutions must to be encouraged to offer easily available capital for environmentally friendly solutions so that small and beginning businesses may support the sustainability agenda. broader adoption can be facilitated by implementing tax credits, subsidies, and low-interest loans for initiatives that benefit the environment. in order to promote inclusive growth and fair access to sustainable technology, policymakers must also make sure that underprivileged people are included in the financial accessibility framework. financial strategy integration with ai may improve decision-making even more, resulting in environmental policies that are more flexible and successful. all things considered, a cooperative strategy that blends financial accessibility with ai innovation may greatly advance the g-7's pursuit of sustainability and spearhead international efforts to tackle climate change. the outcomes presents substantial policy frameworks for tackling the decreasing load capacity factor in the g-7 area caused by globalization and urbanization. policymakers must to adopt measures to effectively handle urban expansion in a manner that is environmentally responsible, with a particular focus on promoting the establishment of eco-friendly infrastructure and intelligent urban initiatives to optimize the use of resources. encouraging the implementation of mixed-use projects and public transit can help mitigate the environmental impact of urbanization. in addition, it is imperative for governments to enforce regulations and provide incentives to encourage firms to embrace sustainable practices in their global supply chains, therefore reducing their impact on the environment. promoting local production and consumption can mitigate the environmental consequences of globalization. in order to sustain the carrying capacity, it is imperative to enforce more stringent environmental rules and standards for both local and foreign businesses. furthermore, allocating resources to renewable energy sources and energy-efficient technology might aid in reducing the negative impacts of growing urbanization and global economic activity. facilitating global collaboration to exchange optimal methodologies and technology for promoting sustainability will be essential. in order to preserve the ecological equilibrium and assure long-term sustainability in the g-7 region, it is imperative to adopt a comprehensive policy strategy that tackles the environmental consequences of globalization and urbanization. global

(1998), tourism includes governmental and private sector endeavors that address the demands and impacts of travel, such as leisure, business, and several other pursuits. it may be internal or worldwide and serves as a significant source of revenue for numerous governments. definitions differ, although guyer feuler initially defined tourism in 1905. the world tourism organization defined “tourism” as follows in order to avoid definitional disputes: “tourism includes the activities of persons traveling and staying in places outside their usual environment for not more than one consecutive year for leisure, business, and other purposes” (couto et al., 2021). tourism is distinct from travel and requires displacement for its existence. three criteria are employed concurrently to define travel as tourism (radhi, 2022), such as, (i) it involves a displacement outside the usual environment; (ii) the travel must occur for any purpose; and (iii) only a maximal duration is mentioned, not a global sustainability research global scientific research 124 minimal. usually, tourism displacement can be with or without an overnight stay (roy & roy, 2015). according to sugiama (2014), a place can become a tourist destination if it meets four tourism components, which are attractions, accessibility, amenities, and ancillary services. rizaldi et al. (2024), on the other hand, say that there are six components of tourism: attraction, amenities, accommodation, activity, accessibility, and ancillary services. according to sunaryo (2013), tourist destinations are distinct regions or geographical areas within one or more administrative jurisdictions, characterized by interlinked elements: tourist attractions, tourist services, accessibility, community, and tourists that collectively enhance the execution of tourism activities. sustainable tourism, an alternative paradigm for tourism development, prioritizes the conservation of natural marine resources alongside fostering economic advancement (adocon et al., 2024). it is a vital concept that aims to balance the exploitation of natural resources while limiting social and environmental impacts (battaglia, 2017). it involves satisfying economic, social, and aesthetic needs while preserving natural, social, cultural, and historical heritage (petrović & marković, 2013). sustainable tourism development requires understanding stakeholders’ perceptions, including local leaders and policy-makers, who play a crucial role in facilitating mutual benefits and mitigating negative impacts on the economy, society, and environment (kattiyapornpong et al., 2018). the tourism industry’s growth, especially in south asian countries, presents opportunities for sustainable tourism development, emphasizing the need for comprehensive strategies to enhance destination competitiveness and achieve long-term growth while considering environmental protection, economic development, and social equity (mathew, 2009). the efficacy of sustainable tourism initiatives is contingent upon tourist behavior (confente et al., 2024). recent research indicates that while tourists express a significant interest in integrating sustainability into their travel experiences (confente & scarpi, 2021; dolnicar et al., 2017), their actual behaviors often diverge from this intention (agag et al., 2020). the study hiariey et al. (2024) delineates three categories of tourism potential: natural, cultural, and human. natural potential pertains to the distinctive flora and fauna of a place, whereas cultural potential encompasses human contributions such as customs and the arts. physical potential encompasses geographical circumstances and tourism facilities. non-physical potential pertains to cultural potential. the economic revenue generated from tourism is affected by attractions, accessibility, public infrastructure, and amenities. the efficient handling of these aspects enhances tourists' duration of stay and revenue (achmad et al., 2023; rizaldi et al., 2024). the significant economic benefits that tourist development brings are probably the main reason why so many nations are pursuing it. the contribution of tourism to the world economy is substantial (ennew, 2003). ecotourism, a sustainable tourism management approach, fosters sustainable growth via community engagement and the preservation of natural resources. in kurdistan, iraq, heightened community engagement amplifies the beneficial impacts of ecotourism (ahmad & balisany, 2023). green tourism emphasizes eco-friendly methods such as waste reduction and water conservation, guaranteeing fair economic advantages and environmental responsibility (daneshwar & revaty, 2024). in punjab, india, ecotourism initiatives safeguard biodiversity, enhance local welfare, and foster sustainable tourism via responsible construction, strategic water management, and rewilding endeavors (chaudhary, 2024). environmental protection is crucial in tourism due to the interdependence between tourism development and the preservation of natural resources, forming a sustainable ecosystem (platon et al., 2023; todorov et al., 2023; xiao, 2022). the rapid growth of tourism (lee, 2022) has led to detrimental effects on the ecological environment of tourist destinations, necessitating the implementation of strategies to protect these areas for sustainable development (cheng & chen, 2022). environmental security measures are essential to prevent losses and maintain the natural beauty of tourist locations because of the influence tourism has on the environment through development, transportation, and operations (arya et al., 2022). overall, sustainable tourism is a multi-dimensional approach global sustainability research global scientific research 125 that seeks to optimize resource usage, maintain ecological processes, and ensure long-term sustainability in tourism development (butowski, 2012). the banshbaria and guliakhali sea beaches in chittagong are drawing tourists and adventure enthusiasts because of their natural beauty and distinct cultures. their tourism potential may enhance earnings, boosting the local and regional economy. tourism development can create employment opportunities and improve the livelihoods of local residents in these areas. identifying sustainable tourism practices is essential to preserve the natural and cultural assets of these coastal areas. however, there is no such study so far to understand and compare the potentials of tourism in these areas in order to conserve the natural settings, recommend better facilities for the tourists to appreciate and ample opportunities for the locals to earn their livelihoods. so, this study is to assess the tourism potential of banshbaria and guliakhali sea beaches with the purpose of fostering sustainable tourism development. it seeks to conserve natural habitats, propose appealing amenities, and offer chances for residents to generate income. the objectives encompass reviewing the current status, challenges, and potentials of tourism, assessing its environmental and community impacts, and formulating suggestions for sustainable tourist development. methodology study area the study area includes banshbaria and guliakhali sea beaches in sitakunda upazila (figure 1). sitakunda upazila occupies an area of 483.97 square kilometers located between 22°22' and 22°42' north latitudes and between 91°34' and 91°48' east longitudes. of this total area, 61.61 square kilometers (12.73%) are covered by forests. it is bordered by mirsharai to the north, pahartali to the south, fatikchhari, hathazari and panchlaish to the east, and the sandwip channel in the bay of bengal to the west. the sitakunda range is a 32-kilometre-long ridge in the center of the upazila, which reaches an altitude of 352 meters above sea level at chandranath or sitakunda peak, the highest peak in chittagong district. banshbaria sea beach this beach is mostly muddy and located fifteen minutes from banshbaria bazar in sitakunda upazila, chittagong (figure 1). a jhauban (a forest full of planted casuarina equisetifolia trees) and a newly emerged sandy field are among the main attractions of the beach (nobi & majumder, 2019). banshbaria sea beach, nestled along the coastline, stands as a serene and picturesque destination that captivates the hearts of its visitors. located in proximity to the bustling city of chittagong, banshbaria offers a tranquil retreat from urban life, drawing tourists seeking solace in the lap of nature. one of the distinctive features of banshbaria sea beach is its mesmerizing sunset views. the beach becomes a canvas painted with hues of orange and pink as the sun dips below the horizon, creating a spectacle that leaves a lasting impression on those fortunate enough to witness it. the tranquility of banshbaria, coupled with the soothing sound of waves gently lapping the shore, provides a perfect setting for relaxation and contemplation. banshbaria's charm lies in its beauty and the relatively less crowded atmosphere compared to some other popular beaches. for those who prefer a more secluded and peaceful environment, banshbaria offers a haven where one can enjoy the beauty of nature undisturbed. global sustainability research global scientific research 126 figure 1: map of the study area guliakhali sea beach this beach is located in sitakunda upazila, chittagong, 5 km west of sitakunda bazar (figure 1). the beach's lush, grassy environment is one of its many wonderful features. this sets the beach apart from other conventional sand beaches. this beach has a vast potential for development (nobi & majumder, 2019). it is located in 22°36'40.09" north latitudes and in 91°37'32.05"east longitudes. its aesthetic and structural features set it apart from other beaches. the water is seen on one side of the horizon, while the keora (sonneratia apetala) forest is seen on the other side. this forest went deeper into the sea. its surrounds resemble mangrove and swamp forests. the wide grass green carpet across the beach has grown bigger than other beaches. in the middle of the green, the narrow groove was pierced. during the tide, the rivers are full of water. the seashore region is home to only one kind of tree, keora, and several bird species, as well as lal kankra or red crab, among the fauna. rarely, deer are occasionally spotted in the dense keora forest. research design a comprehensive study was undertaken to evaluate the geography, tourist conditions, and available amenities of banshbaria and guliakhali sea beaches, emphasizing their natural and cultural characteristics. the research performed a field survey in october 2023, interviewing residents and tourists in the study area. the survey was conducted between 9.30 am and 1.30 pm and 2.30 pm and 5.00 pm. a semi-structured questionnaire survey was global sustainability research global scientific research 127 executed randomly, involving 200 respondents from each location, encompassing diverse age groups, gender, vocations, and educational backgrounds from the sample areas. data collection surveys and in-person interviews were executed to collect data on tourism-related activities, challenges, possibilities, tourist facilities, and the effects of tourism in designated areas, employing a semi-structured questionnaire. data analysis data analysis entails the collection and presentation of gathered information via questionnaires, tables, and graphs, employing statistical tools for quantitative analysis and qualitative analysis, as well as generating visual representations. results and discussion tourist attribute visitors’ analysis shows that most of the tourists visiting the study locations are from the youth group (16-30), which constitutes 72% at guliakhali and 70% at banshbaria. the reason may be the young are more adventurous and nature-freak. during the study, the number of male tourists was found 66% at banshbaria and 58% at guliakhali (table 1). table 1. distribution of tourists by their personal attributes in the study

facilities is the reason behind the lower than anticipated and optimistic involvement of female visitors visiting both the study sites. based on the educational background of the visitors, it was found that graduates (64% at guliakhali and 58% at banshbaria) were the most likely to travel, followed by postgraduates (20% at guliakhali and 14% at banshbaria), secondary and higher secondary school students (small percentage), and primary and illiterate people (very negligible percentage). the study also revealed that students formed the major occupation group (68% at guliakhali and 66% at banshbaria) followed by service holders (20% at guliakhali and 14% at banshbaria), businessmen (5% at guliakhali and 14% at banshbaria) and housewife (5% at guliakhali and 6% at banshbaria). students were higher in numbers as they get more time to visit than others and always move in a group (table 1). seasons and purpose of visiting these places there is a distinct seasonal preference among tourists for guliakhali and banshbaria (figure 2a). more precisely, 66% of tourists in guliakhali and 50% of tourists in banshbaria prefer traveling during the winter season (figure 2a). the main reason for this preference is, essentially, the ideal climatic conditions and the ease of access during winter seasons. on the other hand, 34% of tourists in banshbaria and 26% of tourists in guliakhali choose to visit during the rainy season, while the remaining tourists prefer to travel during the summer (figure 2a). as seen by the majority of visitors, figure 2b shows that taking nature walks and appreciating the stunning scenery are the main reasons people visit these locations. the remaining visitors come here for relaxed get-togethers. (a) (b) figure 2: distribution of visitors by (a) seasons in which tourists prefer to visit and (b) purpose of visiting the destinations tourist origin and cost comparison the survey indicates that majority of the tourists (63%) that visit the sea beaches in guliakhali and banshbaria originate from chittagong. in addition, residents from dhaka (11%), cumilla (10%), feni (9%), and noakhali (8%) are regular visitors to these beaches (table 2). however, due to the considerable distance and lack of knowledge about the place, visitors from other parts of the country hardly ever make the trip. the fact that chittagong is located near these beaches adds to its appeal as a vacation spot. in addition, the total travel expenses are greater for guliakhali (bdt 394) in comparison to banshbaria (bdt 567), mostly due to the fact that visitors to guliakhali frequently engage in shopping at sitakunda bazaar, an opportunity that is not accessible to tourists 50 66 34 26 16 8 0 10 20 30 40 50 60

travel to visit the destination. as a result, tourists who come from faraway places, like dhaka, have to spend more money (bdt 1379), while those who come from nearby areas, like chittagong, have to pay less (bdt 481) (table 2). table 2. comparison between origin and cost in both spots tourist origin banshbaria guliakhali average % of visitor (n=100) cost (bdt) % of visitor (n=100) cost (bdt) %

(64%) believe that the environment is declining due to tourist’s visitation (table 3). the results suggest that approximately half of the tourists in banshbaria (49%) and guliakhali (45%) tend to dispose of their waste in the nearby places followed by 24% of tourists in banshbaria and 38% in guliakhali carry their dry waste in bags. in addition, a total of 27% of tourists from banshbaria and 17% from guliakhali do not produce any garbage (table 3). table 3. distribution of tourists by ways of disposal of wastes tourists’ opinion about nature deterioration banshbaria (%) (n=100) guliakhali

problems faced by tourists in both spots almost all tourists identified some problems which should be taken into consideration for immediate action for development of tourism in these places. the major problems identified by tourists at banshbaria are lack of quality food (29%) followed by lack of sanitation facilities (22%), lack of security (13%), lack of essential goods (12%) etc. (table 5). the major problems identified by tourists at guliakhali are lack of quality food (30%) followed by lack of sanitation facilities (22%), communication problem (12%), lack of security (10%) etc. in addition, visitors from guliakhali encounter an additional challenge: the narrow roads that make local cng the only means of transportation from sitakunda bazaar to guliakhali sea beach severely impede their ability to visit the area. this can be remedied by widening the roads. table 5. distribution of tourists by the problems faced in both the study areas problems faced by tourists responses

natural surroundings, and 6% propose constructing a watch tower or lookout for a panoramic view of the beach. conversely, individuals from banshbaria place a high importance on security, with 26% advocating for it to ensure unrestricted movement, particularly for women. in addition, 25% of respondents propose the creation of eateries, 21% prioritize improving restroom and sanitation facilities, and 16% recommend strategic planting to increase the visual attractiveness of the beach. furthermore, 12% of people express a desire for benches to enhance their beachview experience (table 6). this comparison emphasizes the diverse yet intersecting preferences of tourists at both destinations, emphasizing the necessity for customized enhancements to optimize their overall

level of 7%. in comparison, banshbaria experiences a higher level of noise pollution (12%) due to the use of high-volume microphones. in both guliakhali and banshbaria, there are occasional minor problems. for instance, 6% of people in guliakhali mentioned overcrowding during vacations, while 6% in banshbaria occasionally noted cultural changes (table 7). development needs according to local people people in both areas are shown to support facility improvements, but at different priorities according to the survey as depicted in table 8. for instance, there is a population of approximately 30% residents living in guliakhali who would be ready pay outright store rents with a view on enduring cyclones and storms. also, 26% desire electricity to be more reliable, and while 20% believe that a bridge should be built for people wanting to go to the beaches during monsoon time, 13% insist that dustbins must be put up to collect litter from visitors whereas others demand clean public toilets. likewise, 20% of banshbaria’s inhabitants feel power supply should improve while another 22% are concerned about having tree species which suit their environment. meanwhile, security measures and staying trash cans for proper waste management are claimed by nearly one fifth (19%) of all respondents. furthermore, 15% emphasize the need for structured stores, while 5% emphasize the importance of improved law enforcement (table 8). table 8. distribution of local people by their responses on development needs in the study areas development needs according to local people responses

total of 60% people of banshbaria and 55% of guliakhali were involved in floating or temporary business which indicate the potentiality of tourism area (figure 3). here floating business are more than permanent business because no infrastructural development has taken place in these areas (figure 3). and the socio-economic conditions of the people are not in that position to afford permanent shops so they depend on floating business. global sustainability research global scientific research 133 figure 3. distribution of local people on the type of employment in the study areas challenges of the study areas banshbaria the study identified several issues that are preventing tourists from being fully satisfied with their visit to the banshbaria beach. one of the main factors that has hindered female tourists' participation is security worries. other major obstacles are lack of shops, restaurants, hotels and poor sanitation facilities. the inaccessibility of parking facilities and basic supplies made it challenging for the visitors. there is greater pollution when there aren't enough garbage bins because people throw rubbish everywhere. a visitor's comfort might also be negatively impacted by inappropriate seating arrangements and noise pollution. aside from the misbehavior of tourists, the cutting of trees and the lack of drinkable water are other factors that exacerbate these problems. these factors work together to make the overall visitor experience challenging, which is why extensive environmental and infrastructure improvements are required at banshbaria beach. guliakhali tourists who have visited guliakhali beach have reported certain serious issues that have hampered their overall enjoyment and experience. security concerns, which are also evident in banshbaria, are a major cause for the limited number of female travelers. the lack of good food and poor sanitary facilities are the key-challenges. the communication problems that exist between sitakunda bazar and guliakhali beach and the unavailability of the basic goods also make the tourists' experience less enjoyable. scarcity of parking spaces and sometimes overcrowding are other problems. the environment is at risk due to the wrong way of waste disposal, cutting down of trees, sand extraction from the seabed, and beach erosion due to continuous anchoring. besides that, the shortage of seating facilities and the immoral activities by some tourists, as well as the lack of drinking water, are the main reasons why the visitors are so unhappy. recommendation for the development of the study areas banshbaria addressing the various problems opined by the tourists at banshbaria beach necessitates a holistic strategy. improving safety with concrete tactics can allay the fears of those who see the beach as dangerous, particularly 40 45 60 55 0 20 40 60 80 banshbaria guliakhali in d iv id u a ls ( % ) tourist spot(s) permanent business floating or temporary business global sustainability research global scientific research 134 women. tourist satisfaction and economic growth are dependent on the establishment of shops and other amenities such as snack bars, restaurants, and motels. parking and sanitation facilities must be adequate, with enough washrooms for all visitors. people are growing more aware and making a difference, as seen by proper waste disposal systems and dustbins; however, the use regarding such dustbins must be enforced and properly followed in order to prevent pollution. solving the problem of a scarcity of essential resources, such as drinking water, will go a long way towards improving visitors' experiences. guliakhali in order to resolve the issues in guliakhali sea beach, the following broad strategies are needed. it becomes important to ensure security and enhance the level of tourist participation where women should be considered. thus, increasing the quality of the available food by promoting local producers and sellers will enhance the level of tourists’ satisfaction. there should be a sufficient number of well-maintained washrooms with distinct areas designated for men and women. tourism experience of sitakunda bazar to guliakhali beach would be easier if the communication and transportation system of the two regions is well developed. the concerns with waste disposal require proper methods of waste disposal and management, as well as information sharing where the general public is educated about the conservation of the environment. for guliakhali to be sustainably conserved, it is imperative that the aforementioned unethical activity, tree-cutting, sand extraction, and beach erosion be avoided. in order to prevent future exploitation of the current keora forest, it is also necessary to engage competent personnel. conclusion the study on the potentiality of tourism development in both banshbaria and guliakhali has unveiled a spectrum of challenges that currently hinder the optimal development of these promising tourist destinations. guliakhali seems to have a slight edge because of its natural attractions and higher preference among visitors. both the places boast immense tourism potential, each offering a unique array of attractions that could appeal to diverse visitor preferences. the demographic insights, revealing a concentration of young and adventurous tourists, underscore the potential for adventure and nature-based activities in both locations. with a majority of tourists being students, there is an opportunity to develop educational and recreational offerings that align with their interests. the destinations, primarily attracting visitors from chittagong, can strategize to increase accessibility and appeal to a broader geographical audience. both locations face common issues such as security concerns impacting female tourist participation, insufficient infrastructure, inadequate sanitation facilities, shortage of essential goods, challenges related to waste disposal and environmental degradation need to be addressed through collaborative efforts between local communities and tourism stakeholders. recognizing and building upon these potentials can lead to sustainable tourism development, ensuring memorable experiences for visitors while preserving the natural beauty of banshbaria and guliakhali. addressing common issues, promoting responsible tourism, and involving the local community in development are critical for the long-term success of both destinations. the potentiality of tourism in both banshbaria and guliakhali is substantial, but unlocking this potential requires a concerted effort from local authorities, businesses, and the community. by implementing the recommended measures, these coastal destinations can transform into sustainable and attractive tourist spots, offering memorable experiences while safeguarding their natural resources for future generations. global

environmental tax; financial accessibility; load capacity factor; nordic region global sustainability research global scientific research 55 introduction severe environmental degradation is increasingly in line with not just climate change but also other human activities and catastrophes related to the air, water, and soil (ahmad et al., 2020; alola et al., 2020; islam et al.2023). the developed and developing worlds have made it a priority to prevent temperature rise and damage to the planet (apergis et al., 2023; polcyn et al.2023; rana et al.2024). furthermore, rising global ghg emission levels are mostly caused by variables, including the growth of the urban population, industrialization, financial accessibility, and monetary development (asongu et al., 2020; wanof,2023). with its extensive coastline, dense forests, mountains, rivers, valleys, and arctic tundra in the north and warm regions in the south, nordic nature is unparalleled. a diversified society, ecosystem, way of life, and health have all been impacted by the threat that climate change poses to the nordic region (baral, 2024). norway is dedicated to a sustainable environment and climate policy, and it serves as a worldwide example for the mitigation of global warming (anker, 2018). with around 31% of the gas imported by the eu coming from norway, it is the most significant natural gas supplier among western european nations. therefore, the main driver of norway's gdp growth is the oil and gas sector (zakeri et al., 2022). in light of the foregoing, the initial objective of the research is to analyze the effects of gdp growth, environmental taxes, financial accessibility, urbanization, and artificial intelligence (ai) innovation on load capacity factor (lcf) connections in the nordic region. the nordic countries were chosen because they have become well-known worldwide for their dedication to sustainable growth, environmental quality, and taking the lead on global climate change mitigation (owusu et al., 2024; raihan et al.2022a). for example, norway is now the most sustainable country in the world and plans to become carbon-neutral by 2030. according to projections from the international hydropower association, hydropower accounts for 95% of the country's power generation (malka et al., 2023). the nordic countries have made great progress, but climate change still presents problems, such as higher rainfall, water damage, and rising sea levels (depren et al., 2023). moreover, norway's co2 emissions, with 49.3 mt, placed it tenth globally. in 2018, norway produced 55% of its energy from fossil fuels (owusu et al., 2024). the four nordic nations (denmark, sweden, finland, and norway) are the first to employ renewable energies extensively, have excellent environmental quality, and have enacted environmental taxes (he et al., 2019). the first nation in the eu to genuinely enact green tax measures is denmark. the danish economy has expanded by 78% over the last 30 years, according to official data, while energy consumption has essentially stayed the same (oecd, 2019). the four nordic nations' combined carbon emissions make up roughly 0.96% of all carbon emissions worldwide (bp, 2019). moreover, denmark is at the forefront of the green transition. since 1996, it has effectively cut its co2 emissions by more than half. carlini et al. (2023) report that 47% of the country's 2019 electrical generation came from wind power. because green methods of economic growth are significantly superior to means of progress that degrade the environment, the five sovereign nordic countries have a moderately better level of financial stability than china, the united states, and india (sharif et al., 2023). finland is thought to be among the leaders in environmental issues (wurzel et al., 2020). the success of finland's progressive environmental policies has historically been attributed to the early participation of stakeholders in policy processes (koskimaa et al., 2021). the policy tool used to reduce the usage of energy, which varies depending on the economy and business, is environmental taxes (bashir et al., 2021). several climate change targets, including lower pollution, water disposal, and waste, etc., can be achieved through the execution of the environmental tax to ensure financial and ecosystem effectiveness and clean energy utilization (bakirtas and akpolat,2018; baltagi et al.,2016). the discussion about the financial progress of the e-7, india, and bricst countries, as documented by gao et al. (2024), raihan and voumik (2023), and durani et al. (2023), respectively. according to chen et al. (2019), progress in finance is significant since it can improve the financial system's economic effectiveness in a nation. more energy use is expected to come from faster economic expansion, which may have detrimental consequences on the global sustainability research global scientific research 56 environment. however, technological innovation can worsen the natural world and boost carbon emissions (du et al., 2019; ali et al., 2023). the current research considers the trends and main research areas of ai innovation, financial accessibility, environmental tax, urbanization, and economic growth in the lcf of the nordic territories and offers a structure for upcoming endeavors to investigate. the ecological footprint measures the extent to which human demands for nature exceed nature's ability to provide those requirements (wackernagel and kitzes 2008). this specific tool simply illustrates how human need for natural resources has led to ecosystem deterioration (caglar et al.,2023). siche et al. (2010) suggested calculating the lcf as the ratio of bio to efp to remedy such a deficit. thus, lcf tackles both sides of the debate: the supply of nature and the demand from humans (akhayere et al., 2023; arif et al.2024). an ecosystem can support human demand if its lcf score is one or greater; if it is less than one, human demand cannot be met by the ecosystem (kartal et al., 2023; ridwan, 2023; shiam et al.2024). this study allows us to address the following objectives: what effects do taxation on the environment, financial accessibility, and ai innovation have on lcf in nordic countries? how do gdp and urbanization affect the environmental sustainability of the chosen area? our study is significant as it can determine whether the innovative green solutions and vibrant taxation systems that have been suggested can innovatively foster a green environment and lessen the negative effects of monetary availability, economic growth, and rising urban populations in the nations that have been chosen. analyzing the lcf drivers in the context of the nordic region will add a great deal of understanding to the body of expertise and provide researchers studying the topic with fresh perspectives. the uneven impacts in the selected areas may be examined by using a unique panel ardl approach that considers quite recent variables such as the environmental tax, ai innovation, and financial accessibility on lcf. more sophisticated procedures, including both first and second-generation techniques, are utilized in this empirical study to address the obstacles of heterogeneity and the csd problem. the fmols, dols, and fe-ols assessments were also adopted in our study to verify robustness. several noteworthy empirical findings demonstrated the necessity of appropriate legislation to facilitate the effective use of the latest innovations, provide funding, and enhance policy-level approaches for ecological protection. the remaining portions of this work are organized this way: the literature is analyzed in the "literature review" part. the data, conceptual framework, and methods are presented in the section under "data, model, and methodology." the subsection titled "empirical results and discussion" presents the empirical outcomes and discourse, while the final part titled "conclusions and policy implications" concludes with strategy proposals. literature review numerous investigations have explored the (lcc) theory, the panel ardl model as well as the connections between globalization, economic progress, and the expansion of financial institutions. because load capacity factor (lcf) is still a relatively fresh concept, there is still a lack of research on it in the nordic region. furthermore, not much research has been done on recent variables, including environmental taxes, financial accessibility, and innovations in artificial intelligence. nevertheless, earlier research has influenced the technique and variable choice for these studies. a few of these investigations will be covered in this section. within a conventional development process, adverse environmental effects, destruction of ecosystems, and excessive use of assets drive growth in the economy (khan et al. 2019a; ridzuan et al.2023). this is an undesirable development mode since it is destructive to the long-term survival of humans. using the gmm technique, latiff and faridi (2023) conducted a study in 48 asian nations, analyzing data from 1996 to 2020. the results showed that in the selected nations, environmental degradation is a result of economic expansion. from 1990 to 2018, caglar and askin (2023) explored the connections between gdp and lcf in the top 10 cip areas. according to the study, growing gdp degraded the ecosystem and reduced lcf. similarly, several studies by akadiri et al. (2022) in india, global sustainability research global scientific research 57 addai et al. (2023) within 9 eastern european economies, and shah et al. (2021) in south asian countries also align with this conclusion. ali et al. (2023) found an unexpected long-term negative association (-0.270) between gdp and the lcf in pakistan. dai et al. (2023) evaluated environmental quality and the relationship between green energy (gen) and ecological quality in asean countries using the lcf. they found that environmental quality decreases with economic growth. moreover, empirical studies (sinha and shahbaz, 2017; allard et al., 2018) discovered that the connection between ecosystem quality and gdp expansion was inconsistent, inadequate as well as highly reliant on the substitutes selected, the statistical approach employed, and the volume of data. however, usman et al. (2024) examined a complex link between gdp growth and lcf, with early gains in lcf associated with gdp growth and later depreciation after a certain point in time in china. moreover, jin et al. (2023) found that gdp growth in germany had a u-shaped relationship with lcf. the academic community has become increasingly aware of ai's rapid growth and has focused research efforts on its socioeconomic implications (zador et al., 2023; fosso wamba, 2022). certain scholars have noted the possible effects of ai on ecosystems (john et al., 2022). according to wang et al. (2023), ai significantly reduces ecological footprints. furthermore, there is a growing tendency for ai to have a marginal impact on lowering the ecological footprint (efp) as globalization gets deeper. moreover, ai has shown a greater level of promise in the areas of environmental monitoring and renewable energy (ahmad et al., 2021; ye et al., 2020). as per vinuesa et al. (2020), artificial intelligence (ai) could add considerably to the majority of the 17 goals and 169 targets in the united nations "2030 agenda for sustainable development." artificial intelligence actively contributed to the mitigation of co2 pollution in seven emerging asian nations between 1990 and 2020 through the use of nardl and asymmetric panel causality methodology, as reported by rasheed et al. (2024). moreover, a major factor in the rise in carbon footprints is the utilization of it. in a similar vein, zhao et al. (2023) concurred with this scenario and concluded that, in 30 chinese provinces, ai could reduce pollution density significantly—by 6.63% for every 10% increase in utilization. according to chen et al. (2022), ai may reorganize production factors, give traditional industries information drivers to upgrade, encourage rapid growth of new sectors, increase efficiency in energy use through upgrades to business structures, and boost the quality of the natural world. one effective government policy tool for raising lcf and lowering pollution levels globally is the imposition of environmental levies. green taxes are a sustainable addition to the government's economic policy and a means of preventing pollutants from spreading into the ecosystem (hieu, 2022). governmental entities use stringent alterations, including environmental taxes, to minimize carbon-intensive activities to tackle pressing ecological issues (ulucak et al., 2020). using the qqr approach, depren et al. (2023) executed a study in the nordic countries between 1994 and 2020. the conclusions suggested that the consequence of ecological taxes on co2 emissions was multifaceted. similarly, javed et al. (2023) demonstrated that one of the main factors lowering ecosystem quality is environmental taxation. esen and dundar (2021) highlighted the possible effectiveness of environmental levies in managing environmental plans using data from turkey using the fmols and dols methodologies. bozatli and akca (2024) showed that the application of the ardl technique in the netherlands' environmental tax and conservation investments are both efficient means of guaranteeing environmental sustainability. moreover, adopting the mmqr approach, jahangir et al. (2024) examined the influence of environmental taxes on lcf in the top ten sdg countries between 1994 and 2018. the investigation outcomes demonstrate that environmental taxes have an inverse and substantial impact on lcf within the nations. comparably, between 1994 and 2017, degirmenci and aydin (2021) performed research in several african states. the results indicate that green taxes exacerbated conservation efforts in south africa and boosted ecological damage in cameroon, ivory coast, and mali. numerous researchers, including mehboob et al.(2024) in the top 5 emitting countries, sharif et al.(2023) in nordic countries, dogan et al. (2022) in 25 environmentally friendly countries, and niu et al. (2028) in china concurred with this conclusion, stating that emission a decline improves the environment. global sustainability research global scientific research 58 the concept of financial accessibility (fa) is gaining recognition as complex, and several indicators are helpful when assessing it (tian and li, 2024). financial accessibility is the way of enabling financial goods and the availability of services that are equal to all viable individuals and organizations (menkeh 2021; zaidi et al. 2021). it includes financial accounts, loans for homes, credit cards, trade facilities, atms, savings, and remittances (united nations 2006). the empirical literature (fakher, 2019; zaidi et al., 2019) attests to the fact that the growth of a profitable sector can mitigate environmental damage. islam (2022) examined how five south asian economies' environments were affected by financial expansion between 1980 and 2018. the improvement of finance is destructively linked with the deterioration of ecosystems due to the linear relationship between finance and co2 emissions, which does not diminish as financial inclusion increases. research has shown that fa increases carbon emissions over time in sub-saharan african countries. this highlights the necessity for legislative frameworks that connect financial inclusion programs with restrictions on the environment (ogede and tiamiyu, 2023). raihan et al.(2024a) conducted a study in the g-7 area by using the ardl framework and found that fa harms the ecosystem. however, hussain et al. (2024) found that the integration has a short-term negative impact on carbon emissions and a long-term positive effect using a balanced panel data set of 26 asian countries. on the other hand, in china, feng et al. (2022) and shahbaz et al. (2022) discovered that financial accessibility improves the condition of the natural world. similarly, chaudhry et al. (2022) investigated the fluctuating effects of financial integration on carbon emissions in the oecd economies between 2004 and 2017 using the dcce approach. greater financial inclusion has been shown to have both shortand long-term effects on lowering co2 emissions. due to the substantial shift in population from rural to urban areas, urb's rapid growth, which has been reliant on industrial growth, increased demand for commodities and needed higher output levels (caglar et al.,2023). urbanization affects the lcf in a country that grows swiftly in several ways. balsalobre-lorente et al. (2021) determined that urba enhanced ecological well-being, with a 1% increase in urba decreasing emission levels by 0.389 percent in the brics region. pata et al. (2023) observed that urba reduced lcf in the usa after running an ardl model. similarly, using dkse, alola et al. (2023) analyzed various environmental indicators for the panel of sweden, denmark, finland, norway, and finland. their findings demonstrate that rising emissions of greenhouse gases from urbanization worsen environmental quality. on the other hand, gang et al. (2023) evaluated how the mena area's urbanization affected the environment between 2004 and 2019. urbanization has contributed significantly to ecological sustainability both in the short and long terms, according to research done using the csardl approach. the ardl methodology was applied in the publication by ali et al. (2017) to find a significant detrimental consequence of urbanization on singapore's pollution of carbon. they revealed that the degradation of the environment is not caused by it. moreover, wang et al. (2021) analyzed that urbanization lowers carbon emissions using the ardl methodology; however, the impact is negligible in oecd countries. in order to lower carbon emissions, they advise promoting the urbanization process and utilizing its scale effect. in the same way, khan et al. (2023) showed through the nardl method that urbanization benefits india's environment in the long run. surprisingly, xu et al. (2022) explored the connection between urbanization and lcf in brazil between 1970 and 2017, concluding that urba does not influence lcf. the majority of the literature now in publication focuses on research related to the environment's demand side, and the beneficial and detrimental impacts of explanatory indicators on ecological footprint have been documented. furthermore, a procedure that prioritizes the lcf and considers the supply aspect of the environment is presently in place. a research opportunity has arisen because there are currently no studies looking at the possible implications of green taxes, financial accessibility, and ai innovation on the lcf for nordic economies. in addition, innovation and environmental taxes can improve sustainable development by optimizing the utilization of resources, cutting emissions, leveraging contemporary technologies, and motivating greener lifestyles. a thorough examination of the competitive advances achieved in economies is required by taking into account the most recent timeframes and new global sustainability research global scientific research 59 metrics. thus, by employing cutting-edge techniques like ardl methodologies to assess the validity of the lcc hypothesis in nordic nations, this study contributes to the growing body of literature. methodology data and variables the world bank development indicators (wdi), global footprint network (gfn), global financial development (gfd), and our world in statistics are the sources of the statistics, which cover the years 1990 to 2022. the factors used in the study are listed in table 1. the gfn provides the lcf data, which is measured as gha per person. urbanization, gdp squared, and gdp per capita information from wdi. the number of annual patent applications related to ai is gathered from our world in data and is used to estimate ai innovation. the ratio of deposit money banks' assets to gdp (%) is used as an indication for environmental tax (ent), and data on ent and financial accessibility comes from gfd. the table below presents the logarithmic expression of each factor. table 1. description and sources of variables variables description logarithmic form unit of measurement source lcf load capacity factor llcf gha per person gfn lgdp gross domestic product lgdp gdp per capita (current us$) wdi lgdp2 gross domestic product lgdp2 gdp per capita (current us$) wdi lai ai innovation lai annual patent applications related to ai our world in data lent environmental tax lent deposit money banks assets to gdp (%) global financial development lfa financial accessibility lfa stock market capitalization to gdp (%) global financial development lurba urbanization lurba urban population (% of total population) wdi theoretical framework the load capacity curve (lcc) provides valuable insights into the complex links between environmental sustainability, financial stability, and the development of people, and it is a vital instrument in ecological education (ridwan et al.2023). this curve is important because it demonstrates if the environment's capability of recovering its resources (biocapacity) and how it utilizes human resources (ecological footprint) are balanced or not. the lcc is thought to have a u-shaped relationship, with gdp and gdp square functioning as the primary contributors. a u-shaped curve relationship has been suggested in the context of lcf (pata and tanriover, 2023; pata and ertugrul, 2023; urbee et al.2024), indicating that there are different patterns in the impact of gdp and gdp square on environmental quality. according to wu et al. (2024), there is initially an inverse association between gdp growth global sustainability research global scientific research 60 and resource exploitation and energy use. several researchers (apergis et al., 2023; aydin & degirmenci, 2023; shahzad et al., 2024; pata & samour, 2022) examined the lcc hypothesis in the literature. for lcc theory, we can consider the following equation: load capacity factor = f(gdp, gdp2, yt) (1) here, wealth is expressed by gdp and gdp squared in equation (1), while other factors influencing the load capacity factor are shown by yt. to generate a greater idea of the factors affecting the lcf, equation (2) integrates other noteworthy variables, including artificial intelligence innovation, economic expansion, financial accessibility, environmental taxation, and urbanization. lcf = f(gdp, gdp2, ai, ent, fa, urba) (2) lcf stands for the load capacity factor in equation (2); ai innovation is represented by ai; fa refers to the environmental tax; fa represents financial accessibility; and urba means urbanization. the econometric explanation of equation (3) is given above. lcfit = ∂0 + ∂1gdpit + ∂2gdpit 2 + ∂3aiit + ∂4entit + ∂5fait + ∂6urbait (3) the variables' logarithmic values are shown in equation (4). this conversion improves interpretation and makes statistical results conceivable by breaking down complex interactions into simpler linear forms. llcfit = ∂0 + ∂1lgdpit + ∂2lgdpit 2 + ∂3laiit + ∂4lentit + ∂5lfait + ∂6lurbait (4) empirical method in the nordic region, our investigation used the ardl framework for data assessment to figure out the link across lcf and variables such as gdp, ai, ent, fa, and urba. moreover, we utilized the fmols, dols, and feols techniques to guarantee robustness. to ensure stationarity, the csd, slope homogeneity examination, and unit root assessments (ips, cips, and cadf) were conducted at the start of the inquiry. the estimates for the shortand long-term ardl were then finished. the causal link among the chosen factors was then demonstrated using the dh causality analysis. after a difficult evaluation process, we were able to determine which econometric framework was the most precise and efficient. cross-sectional dependence test we first confirm that panel data indicate cross-sectional dependency (csd) before starting our econometric analysis. for projections to be trustworthy and observations to be reliable, the csd phenomenon must be addressed (grossman and krueger, 1995). due to greater financial integration and the removal of other obstacles, csd in panel data econometrics is going to increase (tufail et al., 2021; voumik et al.2023a; voumik et al.2023b ). if we overlook the issue and think that cross-sections are independent, we might get reliable and consistent results (westerlund & edgerton, 2007). csd is investigated in this study using large panel data econometrics with weak exogenous csd (pesaran, 2015). equation (5) provides a quick explanation of the typical equation used in csd testing below. global sustainability research global scientific research 61 𝐶𝑆𝐷 = √ 2𝑇 𝑁(𝑁−1)𝑁 (∑ ∑ 𝐶𝑜𝑟𝑟𝑖,𝑡 ̂𝑁 𝐾=𝑖+1 𝑁−1 𝑖=1 )……………………… (5) slope homogeneity test slope heterogeneity must be considered when evaluating panel data (voumik et al.2023c). the experiments on slope homogeneity by pesaran and yamagata (2008) are then carried out. the test results are determined by accounting for each participant's weighted slope. the following is how equation (6) depicts the slope heterogeneity: ∆ ̌ = √𝑁 ( 𝑁−1𝑆%−𝑘 √2𝑘 ) and ∆̌𝑎𝑑𝑗= √𝑁 ( 𝑁−1𝑆%−𝑘 √ 2𝑘(𝑇−𝑘−1) 𝑇+1 )………………………………………(6) panel unit root test traditional unit root analyses may yield inaccurate results due to csd issues and slope variability (dogan & seker, 2016). initially, the researchers employed the first-generation ips test introduced by im et al. (2003). the first generation of panel unit root testing does not take heterogeneity, csd effects, or over-rejection of null hypotheses into account (choi, 2001). for this reason, second-generation tests like cips and cadf, introduced by pesaran (2007), were utilized in our study. the ips unit root test is given below: δyi,t = βi + ρi,t + ϑyi,t−1 + ∑ θk∆yi,t−j + μi,t k j=1 (7) in contemporary literature, the ability of cips to regulate heterogeneity and csd has gained popularity (akther et al.,2024). the cips test is conducted using equation (8): 𝐶𝐼𝑃𝑆 = 1 𝑁 ∑ 𝑡1(𝑁, 𝑇)𝑁 𝑡=1 ……………………………… (8) the cadf test has a strong relationship with the cips test. the alternative in the cadf assessment is some crosssection units in the panel do not have a unit root, while the null hypothesis is each cross-section unit in the panel includes a unit root (hossain et al.,2024). equation (9) provides the following method for computing the cadf: ∆𝑌𝑖𝑡 = 𝜑𝑖 + 𝛿𝑖𝑌𝑖𝑡−1 + 𝜑𝑖�̅�𝑡−1 + ∑ 𝜑𝑖𝑗�̅�𝑡−1 𝑚 𝑗=1 + ∑ 𝜌𝑖𝑗 𝑚 𝑗=1 ∆𝑌𝑖,𝑡−1 + 휀𝑖𝑡 … … … (9) here, �̅�𝑡−1 and ∆𝑌𝑖,𝑡−1 represent the mean values of the cross-sectional analysis for both the first difference and lag. panel cointegration test investigating the existence of long-term relationships across the factors under study is crucial once the sequence of integration has been determined (larsson et al., 2001). the pedroni (1999, 2004) heterogeneous panel cointegration assessment is appropriate for csd with distinctive particular results. it was utilized in the research; unlike kao (1999), this method allows the ar coefficients to differ throughout panels. seven statistics are offered by this test to evaluate the cointegration properties; three of the statistics are based on the between-dimension, and four are based on the within-dimension. it is carried out in this manner: 𝑠ℎ𝑖𝑡 = 𝜆0 + 𝛼𝑖𝑡 + 𝛿1𝑖𝑏𝑘𝑑𝑖𝑡 + 𝛾2𝑖𝑖𝑏𝑖𝑡 + 𝛽3𝑖𝑖ℎ𝑟𝑖𝑡 + 휀𝑖𝑡…………… (10) global sustainability research global scientific research 62 where, i=1... n for each firm in the panel and t=1,..., t denotes the time period. the estimated residuals, or 휀𝑖𝑡, reveal how far the long-run association deviates from expectations. panel ardl technique the study employed the ardl model, initially introduced by pesaran et al. (2001), as an innovative way to assess the shortand long-term connections among the model's parameters. this approach allows for cross-sectional heterogeneity, which is necessary to capture the distinct technological and economic environments of the nordic nations. it takes two phases to put the ardl approach into practice. the first step is to adopt the f test to determine whether there is a long-term link between the pertinent variables in the presence of an error correction. after confirming that the f tests from the first process fall within acceptable bounds, the ardl's second step involves estimating the long-run relations' coefficients (hazmi et al.,2024). 𝑙𝑛𝐿𝐶𝐹𝑡 = 𝜑0 + 𝜑1lnlcft−1 + 𝜑2𝑙𝑛𝐺𝐷𝑃𝑡−1 + 𝜑3𝑙𝑛𝐺𝐷𝑃^2𝑡−1 + 𝜑4𝑙𝑛𝐴𝐼𝑡−1 + 𝜑6𝑙𝑛𝐸𝑁𝑇𝑡−1 + 𝜑7𝑙𝑛𝐹𝐴𝑡−1 + 𝜑8𝑙𝑛𝑈𝑅𝐵𝐴𝑡−1 + ∑ ℵ1 ∆𝑙𝑛𝐿𝐶𝐹t−i 𝑤 𝑖=1 + ∑ ℵ2 ∆lngdpt−i 𝑤 𝑖=1 + ∑ ℵ3∆lngdp^2t−i 𝑤 𝑖=1 + ∑ ℵ4 ∆ 𝑤 𝑖=1 𝑙𝑛𝐴𝐼𝑡−𝑖 + ∑ ℵ5∆lnentt−i 𝑤 𝑖=1 + ∑ ℵ6∆lnfat−i 𝑤 𝑖=1 + ∑ ℵ7∆lnurbat−i 𝑤 𝑖=1 + 휀𝑡 … … … … … … … … (11) the ardl model has the ability to evaluate both short-run and long-run factors at the same time, which is one of its primary benefits. furthermore, i (0) or i (1), or whatever frictionally integrated time series variable these variables tend to be, might be applied with this framework. to guarantee an appropriate regression or ardl procedure consequence, appropriate variables must be used (raihan et al.,2024b). the null hypothesis, which claims that there is no cointegration, is compared with the evidence in favor of cointegration (the alternative hypothesis). equations 12 and 13 represent the null hypothesis (h0) and the alternative hypothesis (h1). 𝐻0 = ℵ1 = ℵ2 = ℵ3 = ℵ4 = ℵ5 = ℵ6 (12) 𝐻1 = ℵ1 ≠ ℵ2 ≠ ℵ3 ≠ ℵ4 ≠ ℵ5 ≠ ℵ6 (13) after long-term connections are established, the error correction model (ecm), developed by engle and granger (1987), is utilized to evaluate the error correction term (ect) and short-term correlations. 𝑙𝑛𝐿𝐶𝐹𝑡 = ℵ0 + ∑ ℵ1∆lnlcft−i 𝑤 𝑖=1 + ∑ ℵ2∆lngdpt−i 𝑤 𝑖=1 + ∑ ℵ3∆lngdp^2t−i 𝑤 𝑖=1 + ∑ ℵ4∆ 𝑤 𝑖=1 𝑙𝑛𝐴𝐼𝑡−𝑖 + ∑ ℵ6∆lnentt−i

fe-ols) first, the fully modified ordinary least square (fm-ols) was introduced by phillips and hansen (1990), and then the dynamic ordinary least square, established by stock and watson (1993), was employed. fm-ols modifies the ols to reduce serial correlation effects and endogeneity in the regressors resulting from a co-integrating connection. the fmols method uses a non-parametric strategy to manage the autocorrelation and endogeneity problems (adebayo et al., 2022). in contrast, the dols test takes into account both the timing of differences and their eventual leads and delays through explanatory factors to remove serial correlation in the covariance matrix of errors used to calculate standard deviations (raihan et al., 2023a). the authors further use the fe-ols estimator expanded with driscoll and kraay's (1998) standard errors, which have been proven more robust. d-h causality test lastly, this research employs the dumitrescu and hurlin (2012) causality assessment to confirm the short-term link between variables, which is essential regarding policymaking. this test may be used to predict cross-sectional independence and dependency scenarios. granger causality tests on the conventional panel show that the homogenous null hypothesis is the reason for any causal relationship found in a subgroup of the variable due to a deficiency of cross-sectional data (ahmed et al., 2022). there are certain benefits to the dumitrescu and hurlin (2012) test procedure. firstly, this causality test's standardized, average wald statistics have a conventional normal asymptotic distribution and are easy to compute. furthermore, no specific panel estimations are needed for the statistics. this method can be versatile and helpful for obtaining reliable outcomes during cd as it can calculate both n > t and t > n samples (ahmed and le, 2021). results and discussion summary statistics descriptive statistics and the findings of several analyses that were performed to determine whether the data were normal are given in table 2. the table shows that lcf has the lowest mean value of 0.01950 while gdp squared has the highest mean value of 118.2038. in addition, all of the variables' estimated standard deviations are extremely low, indicating that the data points are mostly centered around the mean and exhibit limited cyclical variation. the data is skewed to the left as the skewness statistics for most of the factors are negative. both the probability values and the jarque–bera analysis revealed that each of the components had a normal distribution. the investigation's findings additionally showed that no variable had a notable departure from the associated mean values. table 2. summary statistics of variables statistic llcf lgdp lgdp2 lai lent lfa

econometric panel data. the pesaran cd test outcomes are shown in table 3. all of the csd statistics values are highly significant at the 1% significance threshold, and for each variable, the value is less than 0.05. the results demonstrate that the null hypothesis, according to which no csd prevails between countries, is rejected for each variable. this suggests that an unforeseen incident that

analysis process. at a 5% significance level, the outcomes of the cips test likewise reveal that lai is the only variable that is stationary at the level form (i(0)). the remaining variables (llcf, lgdp, lgdpsq, lent, lfa, and lurba) are stable at the first difference (i(1)) at a significance threshold of 1%. comparably, the cadf unit root analysis verifies that, at the 1% significance level, only lai is stationary at the level form (i(0)), whereas the others are stationary at the first difference (i(1)). furthermore, every factor stays significant at the level of 1% upon differencing, except lgdp, which maintains significance at the 5% level. these conclusions indicate significant cointegration and indicate that the variables do not have a unit root problem. table 5. results of

covering withinand between-dimension evaluations, are provided in table 05. the p-values for the panel v-statistic and panel rho-statistic (0.2436 and 0.5612, respectively) are greater than the traditional significance threshold, indicating that there is no evidence of cointegration. however, the null hypothesis of no cointegration is rejected because the panel pp and panel adf-statistic p-values (0.000) are smaller than the conventional significance criterion. the figures suggest the presence of cointegration. with a very high p-value of 0.9271, the group rho-statistic in the between-dimension analysis suggests there is insufficient evidence for cointegration in any of the panels. on the other hand, with p-values of 0.000, the group adf and the group pp-statistic both show evidence of cointegration across the panels. according to pedroni's cointegration methods, each factor is cointegrated over a long period. table 6. results of panel cointegration test alternative

(2024) finding that when gdp rises by 1%, carbon emissions in mena nations rise by 79.8%. several researchers such as raihan et al.(2023c) in malaysia, ahmad et al.(2024) in china, addai et al.(2023) in eastern europe, raihan et al.(2022b) in china agree with this and concluded that gdp growth degrades the biodiversity. however, due to the development of gdp, emissions somewhat decrease in china and india (raihan et al.,2024c; raihan et al.,2023b). additionally, an investigation across vietnam by minh et al. (2023) shows that economic growth is correlated with co2 emissions up to a specific threshold; after that, co2 pollutions decline. on the other hand, gdp2 has an encouraging link with lcf in both periods. in the short run, the coefficient has a positive value of 0.681, and in the long run, the value is 0.107. this is significant as the p-value is less than the conventional level for both periods. this finding highlights that though shorter period expansion in the economy is not good for the nordic ecosystem, long-term stable gdp is beneficial for biodiversity. however, ridwan et al. (2024) disagree, stating that gdp2 raises co2 emissions in the south asian region. similarly, in the short and long terms, there is a beneficial connection between lai and llcf; the short-term and long-term results are significant as the p values are 0.0388 and 0.0061, respectively. these conclusions demonstrate that while ai technology has a favorable advantage on the nordic ecosystem. llcf boosts by 0.263% in the near run and 0.128% in the long term for every 1% increase in lai. this could be because the implementation of green initiatives may need ai, which can improve energy efficiency across a range of industries, such as manufacturing, travel, and residence power. by using artificial intelligence (ai), humans can better manage climate change and achieve sustainability while using natural assets (habila et al.,2023, raihan et al.2024d). moreover, technological advancements help bri economies offset the damaging impacts of excessive resource use on the ecology (majeed et al., 2022). similarly, there is an obvious connection between environmental tax and the environment, as evidenced by the beneficial relationship observed between lent and llcf across both short and long periods. this implies that environmental tax could boost ecological conditions in both terms, and the results are significant, with p-values that are less than the usual level in both terms. specifically, a 1% expansion of lent in the short term will spike llcf by 0.429% and in the long term by 0.526%. kartal (2024) found that there is variation in the implication of ent on lcf in g-7 countries. furthermore, ent advantages for the united kingdom, whilst france and germany just partially benefit. galvez (2024) finds that green taxes in mexico must be included in the un 2030 agenda and that governments should implement and assess them to promote environmental protection in the future. the table demonstrates a discouraging correlation between lfa and llcf. the long-term and short-term results illustrated statistical significance outcomes as the p-value is less than the conventional thresholds. specifically, the effect indicates that accessibility of finance stimulates higher monetary and business transactions but may not have global sustainability research global scientific research 67 a positive short-term impact on the ecosystem. moreover, the financial growth was supported by shahbaz et al. (2017) and baloch et al. (2019) to enhance the ecosystem condition in technologically advanced asian nations like malaysia and indonesia, respectively. according to hussain et al. (2023), financial accessibility has a long (short) term beneficial (negative) influence on carbon emissions in the asian economies. similarly, shang et al.(2024) in top emitting countries and qing et al.(2024) in g-2economies agree that fa degrades environmental quality. on the other hand, liu et al.(2024) in china and vietnam and sharif et al.(2024) in asean territories revealed that fa is beneficial for environmental quality. based on both short and long-term assessments, urbanization (lurba) and llcf have an adverse interaction. over time, there will be a -0.567% reduction in llcf with a p-value of less than 0.05 for every 1% expansion of lurba. a notable short-term decrease in llcf of -0.876% is associated with a 1% rise in lurba. this could be because of the continual consequences of urban expansion, which lower ecological diversity and disrupt the natural world, such as the destruction of trees and the removal of natural ecosystems for redevelopment. voumik and ridwan (2023) discovered that population expansion in argentina negatively impacts the ecosystem over a long period, supporting this conclusion. similarly, malik et al.(2024) in pakistan, ekeocha (2021) in africa, and zhang et al.(2021) in china provided a similar conclusion. on the other hand, khan et al.(2024), in 48 bri economies, concluded that urbanization reduces emission levels. table

utilization of three distinct estimating techniques—fmols, dols, and fe-ols to investigate the accuracy of the ardl estimations. the projected lgdp values for each of these methods are 0.256, -0.085, and -0.219, in that order. these results suggest that the nordic countries' environmental quality has suffered as a result of economic expansion. all estimators have significant coefficients at the 1% level, except dols, which is significant at the 5%. these outcomes are consistent with the shortand long-term conclusions of the ardl framework. in contrast, llcf and lgdp2 have an upward correlation, suggesting that long-term economic growth has no negative effects on the nordic ecosystem. in particular, only in the dols estimation is the coefficient significant at the 10% level; in all other cases, it is significant at the 1% level. our findings of the ardl estimation are in line with this assessment. in all three examinations, the llcf variable demonstrates a positive correlation with both lent and lai. in the fmols and dols examinations, the lai coefficient values are significant at the 5% threshold; in the fe-ols test, they are significant at the 1% point. the nordic ecosystems may gain from the adoption and use of ai technology, as evidenced by the fact that for every 1% growth in ai innovation, lcf expands by 0.076%, 0.210%, and 0.603%, correspondingly. this conclusion agrees with the panel ardl computations. in a similar vein, the lent and llcf coefficients exhibit positive correlations in all three estimation techniques. to be precise, for each 1% rise in green taxes, lcf climbs by 0.052%, 0.234%, and 0.054%, respectively. in calculations using fmols, dols, and fe-ols, this variable is statistically significant at the 1%, 10%, and 5% levels, accordingly. this outcome illustrates the beneficial effects of environmental levies on the ecosystems of the nordic nations and is in line with the ardl model. conversely, the llcf variable had adverse interactions with both lfa and lurba, suggesting that greater degrees of urbanization and financial accessibility are harmful to biodiversity in the areas under consideration. using all three estimating techniques, the lfa variable is significant at the 1% level. in addition, a 1% increase in urbanization (urba) leads the llcf for fmols, dols, and feols to drop by 1.562%, 0.543%, and 0.543%, respectively. in the fmols and fe-ols estimations, the variable is significant at the 5% level; however, in the dols estimation, it is significant at the 1% threshold. the ardl model was the main estimating method employed in this work, and these results validate its conclusions. table 8. results of robustness check variables fmols dols fe-ols lgdp -0.256***(0.0362) -0.085**(0.0012)

overview of the findings of the d-h causality assessment for the nordic economy's lcf. at a 1% significance level, the p-value of 0.0032 denotes a statistically significant influence of lgdp on llcf. as a result, it is feasible to reject the null hypothesis and conclude that there is a one-way causal connection between lgdp and llcf. in contrast, there is no significant link between llcf and lgdp because the p-value is larger than the predicted threshold, suggesting that development in the economy has a unidirectional consequence on natural health in the nordic region. a closer look indicates that the connections between lai and llcf and lgdp2 and llcf are also unidirectional. furthermore, as the null hypothesis cannot be ruled out under these circumstances, the findings show that changes in llcf have no impact on lgdp2 or lai. on the other hand, statistically insignificant higher p-values in each investigation suggest that there is no causal link between lcf and lent. moreover, there is no correlation across llcf and lent or between lent and llcf, as the proposed pvalues are higher than the conventional significance thresholds. nonetheless, there prevails a strong causal correlation that is bidirectional within lfa and llcf as well as between lurba and llcf. these coefficients are significant at the 1% significance level, with the p-values being 0.0367, 0.0035, 0.0001, and 0.0047, accordingly. in conclusion, among all the regressor specifications, lgdp, lai, lfa, and lurba are the factors that significantly influence changes in the lcf. table 9. results of

complex relationships underlying economic growth, artificial intelligence (ai) innovation, environmental taxes, financial accessibility, urbanization, and lcf. the study explored the lcf hypothesis using sophisticated econometric techniques to identify variables affecting regional load capacity. the analysis used both first-generation and second-generation panel unit root examinations, verifying the lack of unit root problems in the dataset to address any methodological concerns. moreover, several panel cointegration experiments revealed long-term cointegration among the global sustainability research global scientific research 70 parameters under investigation, highlighting their interdependence. additionally, the chosen variables were characterized by both shortand long-term interactions adopting the ardl framework. the fmols, dols, and fe-ols techniques were applied extensively to discover the correlations between dependent and independent factors and guarantee robust conclusions. the investigation revealed that while financial accessibility, urbanization, and short-term gdp development have a detrimental implication on the lcf in the selected region, long-term economic growth, ai innovation, and environmental taxation have an advantageous effect. furthermore, the d-h causality examination reveals that no causal association between llcf and lgd2, lai, and lent, nor between llcf and lent, was found in the study. moreover, a bidirectional causal association was also explored between lfa and llcf and lurba and llcf. the intricate elements influencing load capacity in the nordic area were examined, emphasizing the role of the urban population and sustainable ecosystem. our investigation seeks to establish green urban growth as well as sustainable financial growth and imposition of environmental taxation to ensure environmental sustainability in the nordic territory. lastly, this study offers a basis for enlightened decision-making to boost resilience and prosperity in the area going forward by advocating approaches that support conserving the environment and equitable growth. the finding of a u-shaped correlation between gdp and environmental sustainability in the nordic region carries significant implications for policy. at first, higher income levels might have a detrimental consequence on ecological health since they lead to greater consumption and industrial activity. nevertheless, once a specific income level is surpassed, higher earnings result in more investments in sustainable technology and practices heightened environmental consciousness, and more stringent regulatory requirements. to expedite this shift, policymakers should provide incentives for green investments and sustainable inventions, especially during the initial phases of economic expansion. introducing progressive environmental levies and subsidies for clean technologies can help alleviate the adverse effects of increasing wealth. in addition, promoting collaborations between the public and commercial sectors and allocating resources towards environmental education can bolster public backing for sustainability endeavors. by employing strategic management techniques, it is possible to ensure that rising earnings contribute to enhanced environmental sustainability. this involves effectively balancing economic expansion with the preservation of ecological resources. this study found that the application of ai technology and the implementation of a green tax contribute to the advancement of environmental sustainability in the nordic region. policymakers should give utmost importance to the incorporation of ai technology in order to improve environmental management, increase efficiency, and promote sustainability in many sectors. in order to accomplish this, governments can offer incentives, subsidies, and grants to both startups and existing enterprises that are engaged in developing ai advancements that have positive consequences on the environment. simultaneously, the implementation and modification of environmental levies to accurately represent the actual cost of pollution can efficiently deter environmentally detrimental practices and produce income for sustainability initiatives. the taxation system should be structured in a progressive manner, with the aim of specifically targeting large-scale polluters while minimizing the financial strain on low-income populations. proceeds derived from environmental levies might be allocated towards the development of ecofriendly infrastructure, advancement of clean technology through research and development, and promotion of public awareness initiatives. in addition, authorities should promote collaboration between the public and private sectors in order to establish a conducive environment for the development of ai advances. nordic nations can strengthen their environmental sustainability, create economic growth, and continue their leadership in global sustainability efforts by strategically using ai innovation and implementing environmental levies. the findings also indicated that the growth of financial accessibility and urbanization have a negative impact on environmental sustainability in the nordic region. policymakers should prudently oversee financial accessibility to prevent excessive borrowing and uncontrolled economic growth. this can be accomplished by allocating financial global sustainability research global scientific research 71 resources to green investments and sustainable projects rather than industries with significant emissions. enforcing rigorous environmental norms and standards for urban development is essential to minimize the negative impacts of urbanization. encouraging sustainable urban planning methods, such as implementing green construction rules, establishing efficient public transit networks, and preserving green spaces, can effectively mitigate the environmental consequences of expanding urban areas. moreover, providing incentives to encourage the use of environmentally friendly technologies in urban infrastructure and housing can effectively improve sustainability. nordic nations may achieve long-term sustainability by including sustainability standards in their financial and urban development policies. this approach allows them to strike a balance between economic growth and environmental preservation, even while financial accessibility and urbanization continue to rise. declaration acknowledgment: n/a

balarabe: alawalbalarabe@gmail.com received: 09 june, 2025, accepted: 25 june, 2025, published: 26 june, 2025 abstract in nigeria’s agri-food sector, the transition toward net-zero emissions has introduced a paradox: firms striving for environmental sustainability are increasingly exposed to financial instability. despite widespread climate pledges, the operational realities of decarbonization remain poorly understood, particularly in emerging markets where infrastructure, energy systems, and regulatory enforcement are underdeveloped. this study investigates the relationship between sustainability transition variables; decarbonization investment intensity, fossil fuel dependence, and esg regulatory compliance—and earnings volatility among 62 ngx-listed agri-food firms between 2018 and 2023. using a strategic tension index based on ebitda volatility, the study employs dynamic panel regression (system gmm), quantile regression, and structural break analysis to capture how strategic commitments to sustainability translate into financial stress. results reveal that while increased investment in emissions-reduction projects raises short-term volatility, fossil fuel dependence, counterintuitively, correlates with earnings stability, likely due to diesel cost buffering in nigeria’s weak power grid environment. moreover, compliance with ngx-mandated esg disclosure frameworks shows negligible stabilizing effects, pointing to symbolic reporting without operational transformation. these findings confirm paradox theory’s central premise: managing sustainability in resource-constrained contexts generates financial contradictions that firms must strategically manage rather than resolve. the study concludes with targeted recommendations, including transitional financing mechanisms, off-grid renewable solutions, and reform of esg reporting enforcement. by linking financial volatility to the architecture of climate transition in a vulnerable sector, this research offers timely information for policymakers, investors, and corporate leaders seeking a viable pathway to sustainability in emerging economies. keywords: decarbonization; earnings volatility; strategic tension; fossil fuel dependence; esg compliance; agri-food sector global sustainability research global scientific research 163 introduction earnings volatility, as a measure of financial unpredictability, has emerged as a key proxy for evaluating strategic tension within firms undertaking sustainability transitions. globally, as corporations commit to net-zero pathways, the cost of transformation, including investments in clean technologies, supply chain realignment, and compliance reporting, has increasingly reflected in fluctuating earnings performance (ahmad & verma, 2022). according to eccles, kastrapeli, and potter (2023), firms with aggressive decarbonization agendas report elevated ebitda volatility during transitional periods, as they balance investor expectations, regulatory pressure, and operational adaptation. this strategic tension is most pronounced in sectors with high carbon intensity and low resilience to energy shocks. in nigeria, the agri-food industry stands at the frontline of this volatility. characterized by weak infrastructure, limited access to clean energy, and fluctuating input costs, the sector has witnessed growing attention to sustainability reforms (johnson & musa, 2024). while many agri-food firms have pledged to reduce their carbon footprint in alignment with national and international commitments, the financial risks associated with implementation remain underexplored. ebitda volatility, used here as a strategic tension index, offers a valuable lens for analyzing the financial pressure points that firms face after publicly committing to net-zero targets. this metric reveals the hidden economic consequences of climate ambition in environments where decarbonization is often aspirational but structurally constrained (babatunde, oyedepo, & adesanya, 2024). three factors are central to understanding this dynamic in the nigeria. decarbonization commitment which is measured by the percentage of revenue allocated to emissions-reduction investments, reflects a firm’s operational response to climate goals. however, investment without systemic support may increase financial strain, particularly among mid-tier firms with limited margins (adeleke, nwosu, & okonkwo, 2023). fossil fuel dependence, captured through diesel consumption per unit of output, exposes firms to cost instability and carbon risk. in nigeria’s unreliable energy environment, firms often rely heavily on diesel generators, undermining the financial gains of green transitions (okafor, adegbite, & nakpodia, 2023). moreover, regulatory pressure which is quantified through ngx esg compliance scores, adds another layer of complexity. while mandatory disclosures aim to promote transparency, emerging evidence suggests that symbolic compliance may dominate, especially in the absence of enforcement mechanisms (eze, okoli, & uche, 2024). these factors collectively influence financial stability, yet the empirical linkage between decarbonization pathways and earnings volatility in developing contexts remains weakly understood. studies such as omodia, aliyu, and hassan (2023) stress that many nigerian firms pursue sustainability narratives without aligning them to risk-adjusted financial planning. similarly, nwankwo, ezeabasili, and okoro (2023) argue that strategic tension in green transitions is heightened in countries with underdeveloped policy support, leading to greater earnings unpredictability. furthermore, ugwu and adejumo (2024) observe that esg compliance has not translated into real operational improvements in most nigerian industries, creating a gap between reporting and transformation. these information point to a critical need for evidence-based research that quantifies how the relationship of decarbonization commitment, fossil energy reliance, and regulatory enforcement shapes the financial terrain for transitioning firms. this study addresses these gaps by developing a strategic tension index based on ebitda volatility to empirically assess how sustainability transitions affect financial performance in nigerian agri-food firms. by focusing on the direct relationships between three critical independent variables; decarbonization commitment, fossil fuel dependence, and regulatory pressure, and post-pledge earnings volatility, the study contributes to understanding how financial stress emerges in resource-constrained transitions. the findings aim to inform not only corporate strategy but also the design of regulatory and fiscal tools that can support more stable pathways to decarbonization. against this backdrop, the study formulated hypothesis in null form are as follows: global sustainability research global scientific research 164 h₀₁: the proportion of revenue allocated to verified emissions-reduction projects shows no significant relationship with earnings volatility in nigerian agri-food firms. h₀₂: the degree of fossil fuel dependence does not significantly affect the financial impact of decarbonization investments. h₀₃: compliance with ngx esg reporting requirements demonstrates no measurable effect on stabilizing corporate earnings during sustainability transitions. literature review concept of earnings volatility (ebitda) earnings volatility has emerged as a critical financial indicator of corporate distress during sustainability transitions, particularly for emission-intensive sectors in developing economies (nwankwo et al., 2023, journal of cleaner production). measured through the standard deviation of quarterly ebitda margins, this metric captures the operational turbulence caused by decarbonization efforts, where nigerian agri-food firms exhibit 2.1× higher volatility than non-decarbonizing peers (cbn, 2024). recent studies demonstrate its sensitivity to both climate policy shocks and energy price fluctuations, serving as a barometer for strategic tension severity (imf, 2023). in nigeria, where 68% of agribusinesses report earnings destabilization post-net-zero pledges (pwc nigeria, 2024), this measure effectively quantifies the financial cost of sustainability transitions. the metric gains particular relevance given ngx-listed firms' mandatory volatility disclosures since 2023, ensuring data reliability (ngx, 2024). its adoption aligns with global research paradigms examining sustainability-finance trade-offs in emerging markets (eccles et al., 2023), while remaining grounded in local financial reporting standards. concept of decarbonization investment intensity the percentage of revenue allocated to science-based targets initiative (sbti)-verified projects has become the gold standard for measuring corporate climate commitment rigor (adekola et al., 2024, business strategy and the environment). nigerian agri-food firms average just 1.2% revenue investment versus the 5% global benchmark, creating a measurable "commitment gap" with financial consequences (pwc nigeria, 2024). this metric's validity stems from its incorporation of third-party verification, filtering out greenwashing claims prevalent in unaudited sustainability reports (eze et al., 2024). the measure captures capital expenditures in renewable energy adoption, clean production technologies, and certified offset programs all critical for nigeria's energy transition (world bank, 2023). recent methodological advances enable precise tracking through audited financial statements' capex disclosures, particularly for ngx-listed firms (uche et al., 2024). its selection reflects growing academic consensus that monetary investment rather than pledge ambition predicts actual emissions reduction (sbti, 2023). concept of fossil fuel dependence (diesel/₦1m output) nigeria's pervasive generator dependence makes diesel consumption per monetary output the most salient operational constraint on decarbonization (babatunde et al., 2024, energy research & social science). the litersof-diesel-per-₦1m-revenue metric quantifies energy transition barriers with exceptional precision, where sector averages of 38l/₦1m triple neighboring countries' intensity (world bank, 2023). this measure outperforms alternatives like energy mix percentages by directly capturing the cost burden of power insecurity responsible for global sustainability research global scientific research 165 15-20% of production expenses (man, 2024). its empirical strength lies in verifiability through combined fuel procurement records and financial statements, reducing reporting bias (cbn, 2024). the variable's relevance has intensified since 2023 diesel price fluctuations caused 32% of nigerian agri-firms to miss emissions targets (nacc, 2024). academic studies confirm its predictive power for decarbonization slippage across african manufacturing (okafor et al., 2023), while aligning with sdg 7 tracking methodologies (unep, 2023). concept of esg regulatory compliance (ngx score 0-100%) the ngx esg disclosure compliance score represents nigeria's most sophisticated regulatory pressure metric, evaluating 92 reporting elements across environmental, social and governance dimensions (ngx, 2024). unlike binary compliance measures, its 0-100% scale captures implementation quality differences, where leading firms score 85+% versus laggards at <30% (sustainability ltd, 2024). the measure's validity stems from independent audits of mandatory disclosures, filtering out superficial compliance prevalent in voluntary reporting regimes (eze et al., 2024). recent research demonstrates its growing influence on investor decisions, with full-compliance firms attracting 18% more green capital (afolabi et al., 2024). the metric's design incorporates nigeria-specific transition challenges, including just energy transition provisions and sme accommodation clauses (sec nigeria, 2023). its adoption follows global best practices in market-based climate governance while addressing local institutional realities (ifc, 2023), making it ideal for studying regulatory efficacy in developing economies. review of related empirical studies decarbonization investment intensity and earnings volatility recent empirical studies reveal complex dynamics between decarbonization spending and financial stability in emerging markets. adekola et al. (2023) analyzed 150 nigerian firms, finding that sbti-aligned investments initially increased ebitda volatility by 18% before yielding stability after 5 years, suggesting a j-curve effect. nwankwo's (2024) event study of ngx-listed agri-firms showed that companies allocating >3% of revenue to clean energy saw 22% lower volatility than peers, though this required concurrent operational restructuring. contrastingly, okafor (2023) found no significant volatility reduction in west african smes, highlighting an "investment threshold" effect. the imf's (2024) cross-country analysis demonstrated that firms combining decarbonization capex with carbon pricing hedges achieved 31% faster volatility reduction. however, pwc's (2024) nigeria-specific survey revealed that 68% of firms under 2% investment intensity abandoned projects due to cash flow pressures. eze (2024) introduced a moderating role of government incentives, showing that firms accessing green subsidies experienced 40% less volatility. most recently, uche's (2025) paradox theory application revealed that firms balancing short-term profitability and long-term investments achieved optimal stability, though this required rare strategic agility. these findings collectively suggest that while decarbonization investments ultimately stabilize earnings, the transition period creates significant financial risks that many nigerian firms are ill-equipped to manage. fossil fuel dependence and earnings volatility the literature consistently identifies fossil fuel dependence as the primary driver of earnings instability during energy transitions. babatunde (2023) established that nigerian agri-firms with >50% generator dependence experienced 2.3× higher ebitda volatility than peers, with diesel price shocks explaining 72% of fluctuations. global sustainability research global scientific research 166 the world bank's (2024) energy audit of 200 firms revealed that each liter of diesel per ₦1m output increased quarterly volatility by 0.8 percentage points. adeleke (2023) demonstrated that companies adopting solar-diesel hybrids reduced volatility by 37%, though high upfront costs limited adoption to 12% of surveyed firms. man's (2024) cost analysis showed that fuel expenses consumed 19-24% of revenues in poultry processing, creating what they term "carbon lock-in by financial necessity." the energy commission (2025) identified a threshold effect firms below 20l/₦1m output could transition smoothly, while others faced existential risks. surprisingly, cbn's (2024) financial stability report found that firms with long-term fuel contracts experienced 28% higher volatility than spot purchasers, contradicting conventional risk management wisdom. most critically, nacc's (2025) policy simulation showed that without targeted subsidies, 42% of medium-scale nigerian agri-firms would face bankruptcy within three years of diesel price shocks, underscoring systemic vulnerabilities. esg regulatory compliance and earnings volatility emerging research paints a nuanced picture of how regulatory pressures influence financial stability during sustainability transitions. ngx's (2023) compliance analysis of 80 listed firms revealed that high esg scorers (>80%) experienced 19% lower earnings volatility, attributed to improved investor confidence. however, sustainability ltd's (2024) audit showed that 61% of these firms engaged in "selective disclosure," with actual emissions averaging 23% higher than reported. eze (2023) found that early adopters of ngx standards gained 15% more institutional investment, but this benefit disappeared after mandate universalization. the sec's (2024) market analysis demonstrated that compliance reduced volatility only when paired with tangible operational changes (β=0.42, p<0.01). contrastingly, adebayo (2025) showed that smes incurred 12% higher volatility from compliance costs without accessing corresponding financing benefits. ifrs foundation's (2024) global benchmarking revealed nigeria's standards lag south africa's in materiality assessment, creating what okpara (2025) calls "empty compliance cycles." most recently, folajin's (2025) hybrid governance model proposed combining ngx rules with traditional accountability mechanisms, showing 31% better stability outcomes in pilot firms. these studies collectively suggest that while esg regulation can stabilize earnings, its current nigerian implementation creates uneven benefits and unintended consequences. theoretical framework the theoretical foundation for this study is anchored on the paradox theory, a contemporary organizational theory that explains how firms experience and manage conflicting, yet interdependent, strategic demands. rooted in the works of smith and lewis (2011), paradox theory posits that organizations often face tensions arising from competing goals, such as the need for short-term financial stability and long-term sustainability transformation. rather than resolving such contradictions through trade-offs, the theory suggests that high-performing firms actively engage with paradoxes, embracing and navigating them rather than avoiding them. at the core of this theory is the recognition that tensions are not signs of failure but inherent features of complex decision-making, especially in dynamic environments. these tensions become more pronounced in firms operating within volatile markets or undergoing systemic transitions conditions that are especially characteristic of nigeria’s agri-food industry amid climate-induced policy shifts. the pursuit of net-zero targets in such contexts creates an organizational paradox: firms must simultaneously reduce carbon emissions, remain profitable, and comply with intensifying regulatory scrutiny, all while operating in environments where energy infrastructure is unreliable and capital constraints are acute. global sustainability research global scientific research 167 paradox theory provides an ideal lens for interpreting the dependent variable in this study: strategic tension, measured through ebitda volatility following a firm’s net-zero pledge. this metric captures the internal instability that arises as firms attempt to navigate competing imperatives. as organizations invest in decarbonization (e.g., sbti-aligned capex), they introduce capital intensity that can destabilize short-term earnings. simultaneously, persistent fossil fuel dependence (e.g., diesel reliance) undermines climate commitments and exposes firms to fuel price shocks, further escalating operational tension. meanwhile, regulatory pressure, as manifested through compliance with ngx-mandated esg disclosures, adds a layer of external accountability that may either mitigate or exacerbate these tensions depending on enforcement strength and firm readiness. scholars such as jarzabkowski, lê, and van de ven (2013) and hahn et al. (2015) have applied paradox theory to sustainability contexts, demonstrating that tension between economic and environmental goals can become a source of strategic renewal if managed effectively. however, they also caution that unresolved paradoxes may lead to performance volatility, internal conflict, or reputational risk. in a study by ebrahim and rangan (2023), emerging-market firms were found to exhibit higher tension levels due to weaker institutional support, further validating the relevance of this framework to the nigerian context. applying paradox theory to this study allows us to frame sustainability transition not as a linear path to decarbonization, but as a dynamic process riddled with contradictions that are financial in nature. the theory underpins the empirical model by justifying the examination of how specific corporate actions (decarbonization investment), structural constraints (fossil fuel use), and institutional pressure (regulatory esg compliance) converge to produce observable financial strain. by exploring these relationships quantitatively, the study builds upon the theoretical proposition that navigating paradoxes, not eliminating them, is central to achieving both sustainability and profitability. paradox theory not only aligns with the core investigative question of this research but also advances theoretical development in sustainability accounting and strategic risk management. it provides a robust explanatory mechanism for interpreting why firms experience earnings volatility post-net-zero pledges, and under what conditions these tensions can be strategically contained or exacerbated. methodology this study leverages nigeria's rapidly improving corporate disclosure environment to conduct a rigorous quantitative analysis of how decarbonization efforts impact financial stability in the agri-food sector. drawing exclusively on verified secondary datasets, the research design overcomes common limitations of survey-based studies while providing policy-relevant insights grounded in actual firm performance. the approach combines advanced econometric techniques with nigeria-specific operational metrics to capture the unique challenges of sustainable transitions in emerging markets. the study analyzes 62 ngx-listed agri-food firms with complete financial and sustainability disclosures from 2018-2023. financial metrics are extracted from audited quarterly reports filed with the nigerian exchange, while decarbonization investments are quantified using sustainability reports that detail sbti-aligned capital expenditures. energy consumption data comes from the national bureau of statistics' annual enterprise energy audits, which provide standardized measurements of diesel use per revenue unit. this triangulation of regulatory filings ensures data consistency while avoiding self-reporting biases common in primary surveys. the sample represents 79% of eligible firms after applying strict completeness criteria, including minimum 16 quarters of consecutive reporting and availability of both financial and esg disclosures. earnings volatility, the dependent variable, is calculated as the rolling four-quarter standard deviation of ebitda margins, annualized to control for seasonality. the primary independent variables include: decarbonization investment intensity (percentage of revenue allocated to verified emissions-reduction projects), fossil fuel global sustainability research global scientific research 168 dependence (liters of diesel consumed per ₦1 million revenue), and esg compliance (ngx's 0-100% disclosure score). control variables account for firm size, leverage, and commodity price exposure using cbn sectoral reports. these operationalizations reflect nigeria's specific context, particularly the diesel dependence metric that captures the operational reality of persistent grid unreliability. table 1: variable measurement variable measurement scholarly source strategic tension index (dv) annual standard deviation (σ) of quarterly ebitda margins following a firm’s net-zero commitment. smith & lewis (2011);

strategic tensions in nigerian agri-food corporate net-zero pledges'. the analysis draws on panel data from 62 firms over a six-year period (2018–2023), exploring the effects of decarbonization investment, fossil fuel dependence, and esg regulatory compliance on earnings volatility. descriptive trend analysis the following chart visualizes annual average trends in key variables derived from the panel dataset. these include ebitda volatility, decarbonization investment (% of revenue), fossil fuel dependence (liters of diesel per ₦1 million output), and esg compliance scores. global sustainability research global scientific research 170 figure 1: trends in strategic and environmental metrics (2018–2023) ebitda volatility (strategic tension index) the trend line shows that ebitda volatility remained consistently elevated across the six-year period, with noticeable peaks in 2020 and again in 2022. these spikes likely reflect periods of external shocks—such as the covid-19 pandemic or diesel price surges—which intensified internal financial strain. high and erratic volatility suggests that firms experienced persistent strategic tension, especially during or after decarbonization commitments, as they struggled to balance operational stability with climate targets. decarbonization investment (% of revenue) the average investment in emissions-reduction projects was modest and largely flat, hovering around 1.5% of revenue. there is no clear upward trajectory, implying that most firms did not increase their climate investments over time. this stagnation signals a lack of deep commitment or financial capacity to support transformational change, reinforcing earlier findings that most firms are decarbonizing more in rhetoric than in resource allocation. fossil fuel dependence (liters/₦1m output) this metric remained high, with only slight improvement observed toward 2023. the stubborn persistence of diesel reliance reflects nigeria’s unreliable electricity grid and the absence of affordable clean energy alternatives. as a global sustainability research global scientific research 171 result, operational emissions stayed high, and firms remained exposed to energy price volatility, one of the key contributors to ebitda instability. esg compliance scores (ngx 0–100%) the only metric that showed a clear upward trend was esg compliance. after the nigerian exchange group introduced stricter disclosure mandates in 2021, firms gradually improved their reporting practices. this reflects growing regulatory influence and investor expectations. however, even by 2023, the average score still fell below the 80% mark, indicating room for deeper, more substantive compliance beyond box-ticking. overall information the trends paint a picture of partial, uneven progress. while external pressure through esg regulation has nudged firms forward, internal investments and operational overhauls have not kept pace. strategic tension, as evidenced by high volatility, remains unresolved, driven by structural energy challenges and underfunded climate strategies. the table 2 below summarizes the yearly average values for all key

ebitda volatility remained relatively high across the years, with fluctuations suggesting persistent financial instability. peaks in volatility, particularly in 2020 and 2022, likely correspond to periods of economic shocks, energy price hikes, or intensified regulatory enforcement, signaling elevated strategic tension during transition phases. decarbonization investment (% of revenue) stayed consistently low, averaging below the recommended global benchmark of 5%. this underscores the limited financial commitment by firms toward emissions-reduction projects, reflecting either resource constraints or low strategic prioritization of long-term climate investments. fossil fuel dependence (liters per ₦1m output) showed only marginal decline, indicating continued reliance on diesel-powered operations. despite global and local emphasis on clean energy, nigerian agri-food firms remain heavily locked into carbon-intensive energy sources due to unreliable power infrastructure. esg compliance scores demonstrated gradual improvement, especially after 2021, likely driven by the nigerian exchange group's mandatory esg disclosure rules. however, average compliance levels still fall short of global best practices, hinting at challenges in full institutional adoption and possible gaps in enforcement or capacity. the data highlights global sustainability research global scientific research 172 a disconnect between climate ambition and operational realities. while regulatory pressure is slowly reshaping firm behavior, the financial and infrastructural barriers to meaningful decarbonization remain significant. table 3: correlation matrix variable ebitda_ v lag_ebit da_v decarb inv. fossil fuel dep reg comp firm size leverage comm.

key variables in nigeria’s agri-food sector decarbonization efforts. ebitda volatility shows minimal linear associations with the primary independent variables; decarbonization investment (r = -0.001), fossil fuel dependence (r = -0.064), and regulatory compliance (r = -0.008) – suggesting these factors alone do not directly explain short-term financial instability. this aligns with paradox theory, where the tension between sustainability transitions and financial performance creates complex, non-linear dynamics that simple correlations cannot capture. the weak negative correlation between lagged and current ebitda volatility (r = -0.113) hints at mild mean reversion in financial performance, where periods of instability are followed by marginal stabilization, though this effect remains modest. notably, the near-zero correlation between decarbonization investment and ebitda volatility (r = -0.001) indicates that merely increasing climate-aligned capital expenditures does not automatically translate to financial stability in the short run. this supports existing findings about nigeria's "commitment gap," where firms make sustainability pledges without adequate financial planning (adekola, 2024). similarly, the slight negative relationship between fossil fuel dependence and volatility (r = -0.064) contradicts expectations from energy economics literature, potentially reflecting nigerian firms' reliance on long-term diesel contracts that temporarily buffer against price shocks, though this merit further investigation through interaction effects. the trivial association between regulatory compliance and volatility (r = -0.008) reinforces concerns about nigeria's esg framework being more symbolic than substantive (okpara, 2025), as higher compliance scores show no meaningful link to improved financial stability. among control variables, leverage demonstrates the strongest positive correlation with volatility (r = 0.128), consistent with financial theory that highly indebted firms face greater earnings fluctuations. conversely, commodity exposure shows a marginal negative relationship (r = -0.087), possibly indicating that firms dealing with volatile agricultural inputs have developed better risk management strategies. the interrelationships between independent variables are particularly revealing – the weak positive correlation between decarbonization investment and fossil fuel dependence (r = 0.076) captures the transitional dilemma where firms attempting to go green remain shackled to diesel generators due to nigeria's unreliable grid. meanwhile, the negligible link between global sustainability research global scientific research 173 regulatory compliance and both decarbonization spending (r = -0.038) and fossil fuel use (r = -0.041) underscores the ineffectiveness of current esg mandates in driving operational changes. these findings collectively suggest that nigeria's agri-food sector faces a multidimensional decarbonization challenge where no single factor dominates financial outcomes. the minimal correlations emphasize the need for more sophisticated modeling that accounts for threshold effects, interaction terms, and temporal dynamics – particularly how the relationship between diesel dependence and volatility might shift after firms cross certain investment or compliance thresholds. the results also highlight potential data limitations, as the restricted sample of listed firms (excluding smes) and possible measurement constraints in sustainability reporting may be flattening observable relationships. for policymakers, the analysis sounds a cautionary note about over-reliance on esg disclosures as a driver of change, while for firms, it underscores the importance of integrated strategies that simultaneously address energy transition risks, leverage management, and commodity price hedging to navigate the paradoxes of sustainable business transformation. diagnostic and robustness test interpretations i. multicollinearity (variance inflation factor vif): all vif values are well below the commonly used threshold of 10 (in fact, all are around 1.00). this indicates that multicollinearity is not a concern in the regression model. each independent variable contributes unique information to the model, improving the reliability of coefficient estimates. ii. heteroskedasticity (breusch-pagan test): lagrange multiplier statistic = 2.34, p-value = 0.89, f p-value = 0.89 the high p-values (much greater than 0.05) indicate no significant heteroskedasticity in the model residuals. this means that the variance of the errors is constant across observations, validating the assumption of homoscedasticity and confirming the appropriateness of ols estimators. iii. normality of residuals (jarque-bera test): jb statistic = 2.52, p-value = 0.28, skewness = 0.20, kurtosis = 2.95 the p-value above 0.05 suggests that the residuals are normally distributed. skewness is low and kurtosis is close to the normal value of 3, supporting the use of standard inference tests for coefficients (t-tests, f-tests) and confirming the robustness of the model under normality assumptions. the table 4 below summarizes the ols regression coefficients and associated statistics: table 4: regression results variable coefficient std. error t-statistic p-value intercept

several important information about the factors influencing ebitda volatility in nigerian agri-food firms pursuing decarbonization. the intercept of 16.4912 (p<0.001) indicates a substantial global sustainability research global scientific research 174 baseline level of earnings volatility, suggesting these firms operate in an inherently unstable financial environment even before accounting for sustainability transition factors. this aligns with emerging market studies documenting heightened volatility in sectors undergoing structural transformations (eccles et al., 2023). the negative coefficient for lag_ebitda_volatility (-0.1185, p=0.032) confirms the correlation matrix's suggestion of mean reversion, where periods of high volatility are typically followed by partial stabilization. this pattern may reflect firms' adaptive responses to financial shocks, though the modest effect size indicates this selfcorrecting mechanism has limited power in nigeria's challenging business climate. the positive coefficient for decarb investment (0.1082, p=0.005) is particularly noteworthy, revealing that increased spending on emissions reduction actually exacerbates short-term earnings volatility. this supports the j-curve hypothesis observed in other developing economies (adekola et al., 2024), where sustainability investments initially destabilize finances before potentially yielding long-term benefits. contrary to expectations, fossil fuel dep shows a significant negative relationship with volatility (-0.0365, p=0.008), suggesting firms with higher diesel dependence experience slightly more stable earnings. this counterintuitive finding may reflect nigerian firms' reliance on long-term fuel contracts that buffer against price fluctuations, though it merits deeper investigation given the energy poverty context (world bank, 2023). the negligible effect of reg compliance (-0.0024, p=0.037) reinforces concerns about the limited real-world impact of nigeria's esg reporting mandates, as better compliance scores barely influence financial stability. among control variables, leverage demonstrates the strongest effect (3.2153, p=0.019), confirming that debtheavy capital structures significantly amplify earnings fluctuations a finding consistent with corporate finance theory but particularly acute in nigeria's high-interest environment (cbn, 2024). the negative coefficient for commodity exposure (-0.0423, p=0.099) approaches significance and suggests firms dealing with volatile agricultural inputs may have developed better risk management practices, though this requires verification through additional research. collectively, these results paint a picture of nigerian agri-food firms caught in a complex decarbonization dilemma. the positive volatility effect of sustainability investments, coupled with the stabilizing (but environmentally harmful) influence of diesel dependence, creates a paradox where going green initially worsens financial performance while maintaining fossil fuel reliance offers temporary stability. this tension is exacerbated by ineffective regulatory frameworks that fail to meaningfully link compliance with improved outcomes. the findings underscore the need for policy interventions that address both sides of this equation perhaps through transition financing mechanisms to smooth the j-curve of decarbonization costs while simultaneously accelerating clean energy infrastructure development to reduce diesel lock-in effects. for corporate managers, the results highlight the critical importance of strategic balance sheets management during sustainability transitions, particularly in controlling leverage ratios that appear to be major volatility amplifiers in this context. hypothesis h₀₁ (decarbonization investment and earnings volatility) the null hypothesis positing no relationship between emissions-reduction investments and volatility is rejected (coefficient = 0.1082, p = 0.005). the positive and statistically significant coefficient indicates that allocating more revenue to decarbonization projects increases short-term ebitda volatility. this aligns with the j-curve effect observed in transitional economies (adekola et al., 2024), where sustainability investments initially strain finances due to high upfront costs and operational disruptions. the result suggests that nigerian agri-food firms face tangible financial trade-offs when pursuing net-zero pledges, as capital diverted to green projects may temporarily reduce earnings stability. this rejection of h₀₁ underscores the need for phased investment strategies or transitional subsidies to mitigate early-stage volatility. global sustainability research global scientific research 175 hypothesis h₀₂ (fossil fuel) the standalone coefficient for fossil fuel dependence (-0.0365, p = 0.008) partially contradicts h₀₂. the significant negative relationship implies that higher diesel reliance reduces volatility, contrary to expectations. this may reflect nigerian firms’ reliance on long-term fuel contracts or diesel-based operational predictability (babatunde, 2024), which could temporarily offset decarbonization-induced instability. however, without testing a formal interaction term (e.g., decarbinvestment × fossilfueldep), we cannot fully reject h₀₂. future research should explicitly model this moderation to assess whether diesel dependence alters the financial impact of decarbonization spending, rather than independently affecting volatility. hypothesis h₀₃ (esg compliance and earnings stability) the null hypothesis claiming no effect of ngx compliance on volatility is not rejected (coefficient = -0.0024, p = 0.037). although statistically significant, the negligible coefficient magnitude suggests esg compliance has no practical impact on stabilizing earnings. this aligns with critiques of nigeria’s esg framework as performative (okpara, 2025), where firms prioritize reporting over operational changes. the result implies that current disclosure requirements lack the enforcement or incentives to meaningfully reduce financial strain during sustainability transitions. thus, while the p-value technically rejects h₀₃ at the 5% level, the economic insignificance of the effect supports its substantive retention. conclusion and recommendations the study's findings paint a complex picture of nigeria's agri-food sector navigating the treacherous path between sustainability commitments and financial stability. the results demonstrate that decarbonization investments, while crucial for long-term environmental goals, currently exacerbate short-term earnings volatility, creating a significant barrier for firms already operating in a challenging economic environment. this volatility stems not just from the capital intensity of green transitions but also from the sector's entrenched dependence on diesel generators, which paradoxically provide a stabilizing effect on earnings despite their environmental harm. meanwhile, the current esg compliance framework fails to deliver meaningful financial stability benefits, revealing a troubling gap between regulatory intentions and on-the-ground realities. these dynamics underscore the unique challenges emerging economies face in balancing climate action with economic viability, where inadequate infrastructure, financing constraints, and weak policy enforcement converge to create a perfect storm of transitional risks. the findings validate core tenets of paradox theory, illustrating how nigerian agri-food firms are caught between competing imperatives, pressured to decarbonize while simultaneously grappling with the financial instability such efforts trigger in the absence of robust institutional support. to address the decarbonization-volatility paradox, policymakers should implement a three-pronged approach. first, for firms struggling with the financial impact of green investments, the government should establish a decarbonization stabilization fund that provides bridge financing during the transition period, coupled with technical assistance to optimize the timing and sequencing of sustainability projects. second, to reduce fossil fuel dependence while maintaining stability, energy regulators must accelerate the rollout of mini-grid solutions tailored to agri-processing clusters, offering reliable renewable energy at competitive rates through public-private partnerships. third, to enhance the effectiveness of esg compliance, the ngx should implement a dual-track reporting system that rewards verifiable emissions reductions with preferential access to green financing, while imposing escalating penalties for firms that fail to back disclosures with tangible action. for corporate leaders, the global sustainability research global scientific research 176 path forward requires integrated transition planning that synchronizes sustainability investments with operational resilience measures including energy diversification, working capital buffers, and stakeholder engagement to mitigate implementation risks. financial institutions have a critical role to play by developing innovative instruments like sustainability-linked loans with volatility-adjusted repayment terms. these coordinated interventions could help break the current deadlock, enabling nigerian agri-food firms to pursue ambitious decarbonization without jeopardizing their financial viability in the process. the time for action is now, as delays will only deepen the sector's vulnerability to both climate risks and transition shocks. declaration the authors declare that this manuscript is an original work and has not

deep learning; water management; ict; sustainability introduction computer-aided models have become highly important in water management since their initial use for the creation and designing of water-related projects in the harvard water program in 1955 (reuss, 2003). over the course of several years, researchers have created physically based models to accurately depict the water system (ws) at different levels of intricacy. these models are commonly employed to assist in the design, operation, and management of the ws (iwa, 2019). nevertheless, the progress of physically-based simulations has come global sustainability research global scientific research 49 to a halt primarily because of the difficulties in comprehending the intricate nature of wss and their intricate connections with alternative options like natural and climate systems, especially when it comes to accurately representing human perceptions, behaviors, and the subsequent impacts; establishing modeling assumptions, different steps, and layout, as well as checking a significant quantity of model variables, which may lead to similarity issue; limited availability and lack of assurance in data for detailed modeling; substantial computational power needed for virtual reality and optimization; and human assets and expertise needed for model upholding and growth, making it challenging to shift between different systems. machine learning (ml), a segment of artificial intelligence (ai), integrates computers to gain insight from information, instances, and observations without predefined guidelines (raihan et al., 2024). it is widely acknowledged that such technology has the ability to revolutionize society, economies, and habitats on a global basis (rahman et al., 2024; tanchangya et al., 2024a, 2024b). these shifts are occurring in response to urgent concerns such as global warming, wildlife decline, and the covid-19 pandemic (butler et al., 2016; raihan, 2024). ml is anticipated to greatly affect academic studies and activities within the water industry. it will aid in tackling diverse water issues, like resource utilization, access to water, water contamination, floods, and famine. this, in turn, will facilitate achieving the united nations' sustainable development goals regarding water. deep learning (dl), a subtype of ml, is extensively regarded as a major catalyst for the recent advancements in ai. dl commonly employs extensive, multi-layered artificial neural networks (anns) to handle substantial unprocessed data sets, hence sometimes referred to as deep networks (raihan, 2023a). traditional ml techniques, including multi-layer perceptron (mlp) neural networks, have limitations when it comes to handling raw data and require specialized knowledge in data preprocessing before they can learn. dl is a useful tool for addressing this issue as it facilitates the automatic extraction of features by leveraging numerous stages of illustrations, commencing with basic data, and moving to higher creative degrees (lecun et al., 2015). common dl methods comprise convolutional neural networks (cnns), long short-term memory (lstm), autoencoders, graph neural networks (gnns), and deep reinforcement learning (drl). dl technologies have achieved significant achievements in various domains, including image recognition, and have already been implemented in diverse business areas, including medicine and commerce. the water industry is gradually acknowledging the significant potential of dl, as seen by the expanding number of academic publications, case studies, and applications in this field (shen, 2018). now is an opportune moment to assess how dl techniques are currently being used in water management and to offer insights into how dl research might advance water engineering and enhance the efficient adoption of these approaches to realistic water issues. figure 1 presents an overview of the use of deep learning for ecological, environmental, and water resource preservation purposes. the current investigation seeks to offer a thorough assessment of the relevance of dl in the strategic development as well as administration of water systems. it analyzed the advancement of dl research and its application in important water-related issues. we also discussed the areas where more progress in dl research is required to foster the advancement of modern water systems and the digitalization transformation in the field of water. this study examines various intelligent ideas for water governance systems and emphasizes the utilization of dl in different aspects of water handling, including demand forecasting, leakage detection and localization, sewer defect and blockage, cyber security and resource tracking, wastewater recycling and control, water quality prediction, rainwater management, and irrigation h. this study also examines the diverse obstacles in implementing dl and analyzing data, offering significant insights to researchers involved in installing water management systems. an in-depth examination of the different facets of water life cycle management will facilitate the generation of ideas to tackle the current water problem and establish efficient methods for distributing higher-quality water to customers. global sustainability research global scientific research 50 figure 1. use of deep learning for ecological, environmental, and water resource preservation purposes (fu et al., 2024). the subsequent paper is organized as follows: section 2 outlines the employed technique. portion 3 compares dl to conventional ml and highlights its advancements. section 4 reviews the utilization of dl in water management, including tasks such as demand projections, leak detection and localization, sewage issue and blockage identification, cyber security and resource observing, wastewater recycling and management, water quality prediction, rainwater management, and irrigation control. chapter 5 provides case evaluations. section 6 demonstrates the challenges, open issues, and prospective trajectories. finally, conclusions are offered in section 7. methodology the research performed comprehensive scholarly work to examine various articles pertaining to the application of ai in water management. the present study employed the systematic literature review methodology which is considered to be a reliable approach for review analysis (raihan, 2023b, 2023c, 2023d, 2023e, 2023f; 2023g, 2023h, 2023i). this report of the review was implemented on prominent databases, including scopus, web of science, and google scholar. the search parameters for these electronic files encompassed smart water management, dl techniques in water management, intelligent approaches to wastewater management global sustainability research global scientific research 51 mitigation, and advanced techniques for integrating rainfall retention. the chosen documents were selected based on multiple specifications, including a potential assessment of the project field, focus on potential executions, precision of results derived from dl approaches for various water conservation strategies, openness to model use, and simplicity in the literature. furthermore, in order to guarantee the excellence of the documents, we select articles exclusively through peerreviewed journals. figure 2 illustrates the inclusion and exclusion criteria considered to select suitable publications. the publications were chosen based on the themes of smart water management, deep learning techniques in water management, innovative approaches to wastewater mitigation, and intelligent methods for rainwater storage optimization. only documents written in english were incorporated for the review study. furthermore, only the articles aligned with the research objective were incorporated into this review from the selected source on the topic. moreover, only articles published from 2020 to 2023 were incorporated in this review. figure 2. the criteria for the document selection. figure 3 delineates the techniques that were applied to the comprehensive analysis in this study. following the selection of the investigation topic, the procedure proceeded with the identification and collection of pertinent articles, the review and summary of diverse source material, and the creation of written resources for publication appraisal. in the consolidation phase, a wide number of documents were compiled and incorporated into theoretical or experimental inspections, enhancing the final work. global sustainability research global scientific research 52 figure 3. the methodological process taken for the bibliometric analysis. advances in deep learning throughout history, ai has had periods of significant progress as well as setbacks. however, in recent times, the advancement and utilization of ai have been primarily driven by dl, which is having a profound impact on numerous industries. dl has made significant advancements in various domains when compared to traditional ml. firstly, it allows for the automated extraction of characteristics from unprocessed data by employing many stages of representation learning, commencing from the basic information and progressing to improve and higher stages (lecun et al., 2015). it obviates the need for attribute engineering and specialist skills in order to acquire traits from raw data prior to their input into ml algorithms. moreover, this enhances the ability to learn by magnifying significant patterns and reducing the impact of unwanted fluctuations in the source data. this is achieved by leveraging the exponential benefits of incorporating numerous hidden layers in deep networks, which allows for the representation of intricate non-linear functions. (lecun et al., 2015; shen, 2018). furthermore, the widespread use of the modified linear unit activation function, represented by the equation f(x) = max (x, 0), and its various modifications, offers multiple benefits: 1) deep networks can be trained quickly because their derivatives, which are either 1 for positive inputs or 0 for negative inputs, allow for computation savings. additionally, the use of error terms contributes to this efficiency. 2) the problem of vanishing gradients can be resolved by utilizing elevated slopes and uniformity. 3) the connection of unseen strata in deep networks can produce actual zeroes for negative inputs, resulting in poor depiction. this is a pleasing characteristic in representation instruction. in contrast, the sigmoid activation function will only yield a zero output, achieving a value closest to zero but not a real zero value (goodfellow et al., 2016). furthermore, the execution of the random gradient descent algorithms can greatly enhance the efficiency of training dynamic circuits, particularly when dealing with extensive datasets. this method achieves efficiency by randomly selecting a minor portion, known as a mini-batch, taken from the learning sample. it continues till the learning ends, reaching convergence. various enhancements have been made to the stochastic gradient descent approach, including the highly employed adam algorithm (kingma & ba, 2014), which has become prominent in the field of dl. in addition, the efficiency and effectiveness of network training have been enhanced via various approaches, including novel structures, unattended pre-training, load exchange, reduced models and distilling, and means of regularization (e.g., dropout) (shen, 2018). the effectiveness of dl is ultimately dependent on the progress made in machine speeds, specifically graphics processing units (gpus), as well as the accessibility of extensive datasets. data parallelization is a frequently employed approach on gpus to speed up the training of dl models, particularly when using mini-batch global sustainability research global scientific research 53 training. the technique involves storing a duplicate of the network and training it on a separate set of information on every gpu. the calculated slopes and costs are then transmitted to the same systems (such as the cpu) for consolidations. after aggregation, the updated parameters are sent back to the gpus for further updates. it can significantly promote the creation of neural networks for extensive databases and enhance the ability of learning. the frameworks of various widely used dl algorithms, such as autoencoders, lstms, cnns, drl, and gnns, together with their main characteristics, are depicted in figure 4, beside the traditional multi-layer perceptron ann. figure 4. multi-layer perceived neural systems and current dl algorithms. (a) a fully connected three-layer neural network employs non-linear activation functions like the sigmoid. (b) autoencoders usually consist of two identical aspects: an encoder and a decoder, which are taught to recreate information by transiting a congestion level; hence, deploying an informal learning strategy. (c) lstm cells, comprising a forget gate, input gate, and output gate, act as the basic parts of lstm networks, allowing the formation of dependency chains in time series data. (d) cnns combine pools and convolution to create higher-order traits from input images. (e) deep reinforcement learning (drl) blends reward instruction with deep computing to educate an agent for the best return via environmental interactions. (f) gnns for graph-structured data to illustrate various interactions involving communication across graph nodes (fu et al., 2022). global sustainability research global scientific research 54 deep learning in water management demand forecasting time series analysis often uses controlled learning to project demand. thus, lstm algorithms are typically used to capture temporal patterns in historical data. by extracting traits from previous time-step needs, they may predict hourly or sub-hourly wishes without considering weather or demographics. a gru-based recurrent neural network (rnn) outperformed typical ml models in accurately and reliably predicting water demand for 15 minutes and 24 hours, according to guo et al. (2018). mu et al. (2020) showed that lstm models can reliably anticipate demand at 15-minute and 1-hour spatial precision. these models were compared to arima, svm, and random forest models for their ability to handle abrupt demand increases. to predict the normal water consumption behavior at a 1-hour interval in a virtual classroom, lstms need several initial training days. based on past data for the following day, these might estimate demand for pump operations (kühnert et al., 2021). as smart water meters become increasingly popular, lstms can effectively anticipate water usage using consumption data. this allows water utilities to improve resource allocation and efficiency. figure 5 illustrates a smart water supply in a water distribution system. figure 5. smart water supply in a water distribution system (wang et al., 2024). nasser et al. (2020) found that the lstm model outperformed svms and random forest models using 10minute smart meter data for 2-20 cairo residences. the lstm model failed to estimate peak demand. recent research shows that hybrid dl models accurately anticipate daily water demand when climatic and sociological parameters are considered. du et al. (2021) forecast daily water intake using mixed lstm. the model prepares initial data with two lstms, periodic wavelet transforms, and principal component analysis. one lstm calculates the initial pattern using a denoised demand series, while another uses consumption leftovers to predict synthetic distortion. the main climatic and vacation features stimulate both systems. using cnn, hu et al. (2019) extracted characteristics from five days of historical water usage data and daily maximum temperatures. these features were entered into a simultaneous lstm algorithm to compute daily water needs. global sustainability research global scientific research 55 the blended cnn-lstm paradigm surpassed lstm, bi-lstm, and cnn in prediction precision. preliminary processing methods such as time series signal breakdowns may improve attribute extraction and gru-based model prediction (hu et al., 2021). leakage detection and localization classification and prediction-based dl leak detection techniques exist. models recognize normal and pathological events using labeled data and pressure, flow, auditory, and vibration inputs. one drawback of this strategy is the strain of acquiring and classifying a lot of data. hydraulic models can manufacture artificial training data (javadiha et al., 2019). forecast-oriented techniques use dl models to predict system states like pressure and flow. using a threshold, it classifies disparities between expected and observed event values. cnns are the main dl leak detection and localization method in literature. cnns are trained to classify events as normal or abnormal using labeled data in most research. the article describes several prediction-based dl algorithms. wang et al. (2020) predicted water consumption using lstm. this method performed well in detection precision, actual positive rate, and false positive rate. this study will focus on cnn classification based on pressure/stream data, sound/vibration data, and input formats. pressure data is used to create cnns to find leaks at numerous sites. six cnn models were trained using pressure data from fang et al. (2019). they manually categorized leakage events using water distribution system (wds) statistics from a laboratory platform. top performers cnn model used 21 and 8 pressure sensors to achieve 97.33% and 92.11% accuracy. from 96.43% for one leak to 91.56% for three, accuracy decreased. due to the large number of sensors used (8 to 21 for a 400-meter network), which is not practical for real-world networks, accuracy is great. zhou et al. (2019b) advised using hydraulic models to create pressure data with several leaks for training. hydraulic models generated synthetic data before this. however, those data were generated under typical conditions with little or no leakage. zhou et al. (2019b) developed a completely linear densenet to effectively identify wds leakage characteristics and localize pipe leaks. they detected 200 leak occurrences per pipe and showed that the program can precisely locate pipe breaches. javadiha et al. (2019) trained cnns with simulated leaking data, while fan et al. (2021) trained autoencoders. however, they created pressure residual maps by removing sensor pressure data from hydraulic network model pressure estimates. these maps were then converted into 2d images to train cnns to find leaks. pressure residual maps analyze all probable leak locations, although hydraulic modeling uncertainties may affect their accuracy. synthetic data for leakage location (javadiha et al., 2019; zhou et al., 2019b) and detection (fan et al., 2021) considered unknown hydraulic models, such as random demands and leak sizes. cnns (nam et al., 2021) or autoencoders (cody et al., 2020) can assess pipe pressure variations and cracks' acoustic and vibration data. elasticity waves across the pipe create these signals. these models characterize events as normal or aberrant. kang et al. (2018) trained and tested a one-dimensional cnn on 1580 normal and 660 aberrant signal pairs from accelerometer sensors in a seoul water distribution system (wds). they used a support vector machine to identify feature types and denoising and a bandpass filter to improve detection accuracy. shukla and piratla (2020) used a cnn derived from a pre-trained alexnet architecture to detect pvc pipe leaks in scalogram images without preprocessing. using experimental pipeline testbed data, they accurately determined leak diameters and places. a 2d cnn-based autoencoder helped cody et al. (2020) detect leaks in acoustic data spectrograms with 97.2% accuracy. jiao et al. (2021) used cctv footage and an autoencoder to detect pipeline irregularities, expanding its use in water system surveillance when elastic waves flow through pipes. cnn input data format has been extensively studied due to its high link with recognition and identification precision. javadiha et al. (2019) and m. zhou et al. (2019a) investigated leak identification and localization global sustainability research global scientific research 56 using two-dimensional pictures from one-dimensional pressure data. cnns are ideal for turning audio signals into two-dimensional pictures, so cody et al. (2020) studied this. this process may lose data and raise computational expenses (zhou et al., 2021). kang et al. (2018), fang et al. (2019), and zhou et al. (2021) used 1d cnns to directly evaluate 1d time series signals for leak diagnosis by extracting features from vibration and pressure signals. before inputting raw data into a 1d cnn, rahimi et al. (2020) used fft, wavelet transformations, and time-domain characteristics to efficiently identify leaks in plastic and composite water tanks. guo et al. (2021) created a time-frequency cnn to collect leaking spectrograms at various resolutions. spatial clustering with cnns to discover leakage zones and transfer learning with pre-trained models like alexnet are two methods cnns use to find leaks. satellite images and cnn models have also been used to detect leaks. these approaches cannot monitor in real-time and often cause false alerts due to satellite photo resolution (shukla & piratla, 2020). figure 6 illustrates the architectural diagram of the intelligent soundassisted water leak detection system. figure 6. leakage detection and localization system by using a deep learning approach (tsai et al., 2022). sewer defect and blockage cctv videos are used by expert inspectors to inspect sewers inside. this procedure is laborious and timeconsuming. cnns are becoming useful for automatic sewer flaw detection. their performance in these pieces has been particularly impressive: 1) cctv image categorization by defects 2) object identification: identifying defects and their locations; 3) semantic segmentation: labeling defect-related pixels. figure 7 presents the architecture of detecting sewer defects and blockage by using a deep learning approach. global sustainability research global scientific research 57 figure 7. detecting sewer defects and blockage by using a deep learning approach (yusuf et al., 2024). image classification kumar et al. (2018) trained binary classification cnns to detect specific problems. to save training time, meijer et al. (2019) constructed a single cnn to classify frames by defect. gutiérrez-mondragón et al. (2020) used cnn to detect sewage issues and pipe obstructions. famous cnns were analyzed for sewer issues by experts. the hierarchical classification system employed by xie et al. (2019) distinguished between normal and defective pipes and subsequently categorized defective ones. li et al. (2019) used resnet18 in a hierarchical architecture with residual learning from he et al. (2016). chen et al. (2018) used squeezenet for its improved extraction. chen et al. (2019) improved a binary identification cnn with a cost-sensitive activation layer and cost-mean loss. kumar et al. (2020a) showed cnn weights and changes using class activation mapping. finally, moradi et al. (2020) used cnns to locate problems in sewer frames by distance. object detection previous investigations have categorized and localized frame faults. classification algorithms struggle with several defect kinds in a single image, although object detection models help. cnn-based approaches are divided into region-based (two-stage) and one-stage detection. r-cnn was faster for cheng and wang (2018), although zhang et al. (2018) used vgg-16. instead, yin et al. (2020) used yolov3, a one-stage network, for real-time sewer problem detection. kumar et al. (2020b) found that yolov3 is faster and better for onsite detection, but faster r-cnn is more accurate for offsite evaluation. wang et al. (2021a) used quicker r-cnn to track flaws and count defects in successive video frames. semantic segmentation image semantic segmentation models can label each pixel of a recognized object. kunzel et al. (2018) employed a two-stream cnn, the full-resolution residual network (frrn), to automatically detect and categorize sewer pipe failures and structural issues. cnn processed unrolled and stitched cctv footage. pan et al. (2020) improved cnn-based u-net sewage problem segmentation by integrating feature reuse and attention blocks. wang and cheng (2020) used dilaseg, a deep cnn with dilated convolution, and a dense conditional random field-based rnn. dilaseg extracts feature maps, whereas crf-based rnn resolves local ambiguities. wang et al. (2021b) also suggested studying semantic segmentation data to analyze sewer conditions and operational and maintenance difficulties. global sustainability research global scientific research 58 cyber security and asset monitoring the u.s. department of homeland security has designated water and wastewater infrastructure as a key cyberattack target in the 16 essential infrastructure sectors, citing various cybersecurity issues. this sector was the third most targeted in 2015 after industry and energy, with 25 cybersecurity incidents (hassanzadeh et al., 2020). thus, practical and scholarly attention to water infrastructure protection has grown. dl methods including lstm, autoencoders, and gnns have enhanced high-dimensional intrusion detection. inoue et al. (2017) trained an lstm model with water treatment plant normal operation data and tested it with 36 attack scenarios. taormina et al. (2018) found that autoencoders outperformed xgboost and lightgbm in 14 water distribution system attack scenarios. evasion attacks against deep autoencoder-based detectors were examined by erba et al. (2020). deng and hooi (2021) found that an attention-based gnn detects water treatment system cyberattacks better than baseline models. tsiami and makropoulos (2021) showed that convolutional gnns may detect water distribution system assaults using scada data linkages. urban water systems (uws) research is needed to reduce threats from water infrastructure digitization and ai. uws cybersecurity best practices must be developed, and dl techniques like lstm, autoencoders, and gnns can improve security and identify threats. erba et al. (2020) applied adversarial machine learning to detection systems, however, taormina et al. (2018) suggest testing on real-world cyber-attack situations. deep learning can be used to monitor water assets as a soft sensor or surrogate model in addition to anomaly identification. lack of sensors or cyber system breakdowns makes water system measurements inaccessible. soft sensing uses secondary measurements to forecast missing primary data. the researchers trained 2d cnn and lstm models using oneminute operational data from 100 sensors at a water treatment facility over a year. researchers used several linear regressions to merge these models. lower root mean square errors showed that the combined technique predicted better than cnn and lstm models (cao et al., 2018). especially when the 100 sensors are offline, an ensemble model can forecast flow and water level. in wastewater treatment facilities (wwtp), lstm models accurately predict key variables (cheng et al., 2020). a multi-layer perceptron with layered restricted boltzmann machines (wu & rahman, 2017). based on a limited collection of nodal pressure data, we rebuilt pressures at all nodes using a gnn with k-localized spectrum filtering. this method had an average relative error of less than 5% on three benchmark networks with a 5% observation ratio. hajgató et al. (2021) conducted it. this shows that gnns can be used as soft sensors or alternative models to assess network pressure. belghaddar et al. (2021) used gnns to fill voids in wastewater network pipe dimensions, materials, and system statuses. cnn was used to monitor time fluctuations of the fat-oil-grease layer and other hydraulic processes in a wastewater pump sump (moreno-rodenas et al., 2021). it predicts pump sump failure. wastewater recycling and management forecasting real-time water treatment parameters is difficult. data is used to estimate the precaution process in municipal wastewater through anaerobic membrane bioreactors by li et al. (2022a). they tested two anmbrs for a year, evaluating reactor temperature, cod, flux, effluent cod, ph, and other wastewater treatment variables. they analyzed these parameters using multiple deep learning (dl) architectures, and a cnn predicted outcomes with 97.44% accuracy. the cnn was also calculated in under a second, improving the anmbr treatment result prediction. wwtps reduce pollution and ecosystem damage. they produce a lot of sludge and ghg, necessitating additional optimization (badeti et al., 2021). madrl was used to optimize wwtp dissolved oxygen and chemical dosing by moreno-rodenas et al. (2021). optimizing their life-cycle assessment (lca) lowered ecological impacts including costs, energy consumption, and ghg relative to a global sustainability research global scientific research 59 baseline scenario. the lca-driven strategy surpassed a cost-oriented method in environmental benefits, underscoring the relevance of impact elements when retrofitting wwtps, which need substantial data analysis. fog in wastewater pumping stations causes infrastructure failure (nieuwenhuis et al., 2018). if suspended soils are not effectively transported to pump suction inlets, large clusters of particles can create thick, hard fog layers. the lack of fog layer data is the biggest mitigation challenge. chen et al. (2021) monitored water pumping station fog layers with an automated camera system. the system recorded data often for months. the pump sump uses a novel computer vision model that analyzes optical images using dl techniques to account for fog layer dynamics and other hydraulic phenomena. additionally, this gadget monitors the water pump station and provides standardized high-frequency fog layer data. this data is crucial for understanding fog buildup and movement. the camera-based identification method had a 0.11 root-mean-square error and 0.901 nash-sutcliffe efficiency. several wastewater treatment experiments improve recycling efficiency and eliminate pollutants by lowering fuel emissions, expenses, and energy use. figure 8 illustrates an innovative wastewater treatment system. figure 8. an innovative wastewater treatment system (lin et al., 2022). water quality prediction different dl and ml models analyze water quality for different uses. this section discusses applications, infrastructures, and methods for assessing water quality for various purposes. figure 9 presents the application of dl in different water systems. water quality is threatened by worldwide water contamination. these applications measure pollutants using ml and auto-ml models. however, math skills and model-making are required. since water quality assessments require time-series data, dl models are best for measuring it. khullar and singh (2022) say dl concentrates on "bi-lstm." monthly data for the yamuna river quality report in new delhi was collected from 2013 to 2019. bi-lstm prioritizes training and missed-value imputation. this estimate is essential for accurate measurement. finding the best missing value-filling method is the first step of the bi-lstm. the second phase creates input-based feature maps. training is the third stage. the fourth phase optimizes the loss function to reduce learning errors. the experiment measures bod and cod. palla cod values are mse = 0.015, rmse = 0.117, mae = 0.115, and mape = 20.32. values from bod analysis: mse global sustainability research global scientific research 60 = 0.107, rmse = 0.108, mae = 0.124, mape = 18.22. compared to other methods, the proposed one is more reliable and has fewer errors. smart sensors improve water quality monitoring applications. nemade and shah (2022) collected water quality data with smart sensors. next, they clean sensor data to remove missing values and outliers. the g-smote method extracts traits for learning. this model optimizes a multi-class dl model utilizing an mdlnn neural network and hyperparameter tuning. step-by-step learning from new data is made easier with this paradigm. the model's identification loss is 0.0415% and precision is 99.34%. figure 9. application of deep learning in different water systems (zhu et al., 2022). prasad et al. (2022) suggested that automated dl algorithms improve water quality evaluation. auto dl is a promising new technology. involves evaluating and building models with little or no coding. the execution time is shorter than typical dl algorithms. the auto-dl model is 1 percent less efficient than standard dl models in binary data measurements, which are above 1.8 percent accurate. in multi-class data models, contemporary models are around 1% more accurate than auto-dl. standard dl achieves 98-99% accuracy, whereas auto dl achieves 96-98%. it helps choose the right dl model automatically and reduces the time needed to get them in real-time. thus, auto-dl allows for more real-time problem implementation flexibility. rainwater management water collection and management require accurate precipitation forecasts. rainwater is the main agricultural and domestic water supply. predicting precipitation is important and fascinating worldwide. this forecast is crucial for governments that use hydraulic converter power plants to generate energy from rainwater reservoirs during the rainy season. bhattacharyya et al. (2021) examined andhra pradesh meteorological service rainfall data for one year. the partitioning technique splits features into training and testing datasets. two ml and one dl models make up this system. cnn was utilized for dl linear regression and svm for machine learning. the neural network had 77.17% accuracy, the linear model 48.8%, and the svm 32.5% throughout testing. dl algorithms outperform ml in rainfall data predicting, especially with irregular data patterns. deep learning global sustainability research global scientific research 61 algorithms seem more suitable for this because of their precision. water conservation is not optimum in most rainwater gathering systems. creating communal rainwater harvesting storage facilities in cities is crucial, but obtaining approval may be difficult. the system's viability is complex, requiring many human evaluations (lani et al., 2018). complex system viability requires multiple manual assessments. gaurav et al. (2021) automate the entire procedure with computer vision. they use ml and dl algorithms for image ceiling division, thickness computation, precipitation forecasting, and tank positioning. rainfall projections are made using sarima continuous modeling. the mask r-cnn separation technique used canny edge recognition and shape mapping to estimate the rooftop reservoir. thus, the system can predict the mix's metrics break even and analyze installation feasibility. irrigation control water for other worldwide uses is threatened by excessive groundwater extraction for agriculture. it also threatens the world's drinkable water supplies (ding et al., 2021). various soil textures are classified to determine irrigation needs. dl models are essential for effective categorization. this complex soil texture classification uses neural networks and frameworks. kurtulmuş et al. (2022) assessed the water needs of three soil textures under different lighting situations using a proximal sensing system with a color camera, dl, and computer vision. to simplify image training, they created an imaging system using deep convolutional neural networks. this study classifies water textures using five deep-learning architectures. alexnet, googlenet, resnet, vgg16, and squeezenet are neural networks. alexnet is the best model with an f1 score of 0.9973. with 16.92 ms processing time, google net and resnet identify the fastest. they show that dl algorithms significantly predicted agricultural region irrigation needs under diverse scenarios. effective water management requires understanding the operational dynamics of large-scale irrigation handling and its rapid response to varied pressures. raei et al. (2022) claim to have constructed a regional irrigation control system classification dl model utilizing remote sensing photos. a u-net architecture is being integrated with resnet-34. this was achieved by testing model topologies, hyperparameters, class weights, and picture sizes. transfer learning improved model training efficiency and performance. this method is used in urban and rural regions with four irrigation systems. the us department of agriculture's national agricultural imaging program provides 8,600 high-quality images with exact ground-truth observations. the model's data segmentation accuracy was 72%– 86% for validation, 85%–94% for training, and 70%–86% for testing. global transferability gives the dl approach versatility. this work reveals how transfer learning, imbalanced training datasets, and varied model architectures can discriminate irrigation kinds. li et al. (2022b) created a uav velocity measurement system for large rivers. the optical flow approach and yolov5 dl algorithm use the monocular range to accurately measure velocity and transform pixel distance into the actual distance in this system. in the yongji canal, inner mongolia's river-loop irrigation region successfully adopted the method. the procedure yielded high-quality photographs and consistent measurements. jayasinghe et al. (2022) predicted ep across queensland, australia, using feature selection and a hybrid lstm model with component analysis. time series analysis was used to evaluate daily data from august 31, 2002, to september 22, 2022. this study shows a root mean square error below 20% and a kling-gupta efficiency above 87%. the model calculated and predicted daily ep values more accurately than standalone dl hidden layer neural networks and decision-tree-based models using an upgraded feature selection technique. managing and adjusting irrigation requires monitoring evaporation. case studies global sustainability research global scientific research 62 artificial intelligence (ai) for smart water management systems in all sectors, ict usage has increased. advanced data analytics optimizes water delivery and reduces costs. several industries can use ai to improve water use decisions. ict and ai would help accomplish the sustainable development goals for water management and sanitation (jenny et al., 2020). ai may efficiently manage water limits by evaluating population density and enforcing leakage regulations. smart water management—a case study of korea the water resources corporation and iwra are developing an advanced water management system. this strategy uses ict to quickly offer real-time water data to the iwra to address global water issues. the advanced water management system tracks water, optimizes irrigation, detects leaks, and uses ai algorithms to mitigate floods. krishnan et al. (2022) combined iot detectors, gis observing engines, and satellite data. ai enhances the system by automating services in many situations, improving decision-making. grid intelligence water case study integrating current water management technologies is difficult. water distribution across sectors during the water crisis takes enormous resources. citywide water metering must be accurate and effective. verizon released grid wide intelligent water solutions in 2018 as a cloud-based smart water metering system for southeastern us communities. water meter sensors monitor and control water usage, while the iot gateway allows secure, efficient communication across multiple locations. water leaks and abnormal water consumption are detected and fixed using machine learning. smart water management most regions use smart water management (swm) to efficiently manage modern water resources by integrating policies and technologies. nickum et al. (2020) detailed national solid waste management methods in a concise report. mexico, korea, and france developed a smart flood-handling method using iot and ai for predictive analysis. the mexican "pumagua" effort used sophisticated water resource networks and data monitors to improve water quality and reduce use. south korean experts created the hydro intelligent toolkit program. this toolset provides advanced water management solutions using hydrological data, precipitation forecasts, flood assessments, and groundwater measures. the intelligent iot network analyzes data to measure. smart water management towards future water sustainable networks ramos et al. (2019) examined and improved modern portuguese water distribution pipes. the water business has faced many challenges in the previous decade in achieving efficiency and ethics, including interpersonal, scientific, and ecological aspects. intelligent technology helps water-smart cities and the energy nexus develop through effective water planning and management. smart city technology improves service quality, cost, and system performance. this analysis shows that monitoring and water loss control systems maximize efficiency by reducing water losses and costs. these efforts raised the global ranking of the most efficient cities from 20th to 5th. the analysis shows that the water industry has technological and economic possibilities for microglobal sustainability research global scientific research 63 hydropower projects. these projects can improve power conversation and reduce co2 emissions. the case study shows 12-year savings of 57 gwh and 100 mm3. cost savings reduced co2 equivalent emissions by 47,385 metric tons. challenges, open issues and future directions the primary obstacles associated with dl in water management can be roughly categorized into several key groups, as depicted in figure 10. the major challenges for the practical deployment of dl in water management include algorithmic development, multi-agent platforms, virtual clones, data quality and availability, security, context-aware data analysis, and training efficiency. figure 10. major obstacles of dl application in water resource management. data quality and availability dl networks leverage substantial datasets to train an intelligent system that classifies large test data or real-time info coming from sensors or images used in water management and safety systems. we establish restrictions to govern the procurement of data from scientific and commercial enterprises, given their significant sensitivity and potential exploitation for gaining competitive advantages. legal and political limitations greatly complicate the acquisition of essential data from government organizations for research and development. data is constrained by demographic limitations. when there is a substantial need for extensive real-time data to train the dl algorithm, apprehensions regarding its quality simultaneously emerge. acquiring a large volume of data challenges of deep learning in water management data quality and availability security context aware data analysis training efficiency algorithmic development and learning system design multi-agent systems digital twins and autonomous systems global sustainability research global scientific research 64 for training makes it hard to assess the quality of individual data elements. therefore, we cannot claim that the trained model is based on high-quality data. inadequate pre-processing may lead to difficulties such as outliers or noisy data, increasing the trained system's vulnerability to errors.to address challenges related to data quality and availability in the application of deep learning to water resource management, it needs to employ strategies such as: augmenting data collection via advanced sensors and iot devices, applying data imputation techniques to address gaps, integrating domain knowledge into model architecture, utilizing data augmentation to expand sample size, and investigating hybrid models that merge deep learning with physics-based methodologies to enhance accuracy and robustness, particularly in scenarios of limited or unreliable data. to address data limitations in real-world dl applications for water management, essential strategies encompass: augmenting data collection via sophisticated sensor technology, applying data imputation techniques to address gaps, utilizing semi-supervised or unsupervised learning approaches in the absence of labeled data, harnessing transfer learning to adapt models across diverse water systems, and integrating domain expertise to develop more resilient and pertinent models; all while addressing the specific challenges of data quality, spatiotemporal variability, and restricted accessibility in water management systems. security dl networks utilize a substantial volume of data to train water management systems. this data is either opensource or may be managed by various individuals within the inquiry or commercial domain. the modifications in the input data are indicative of the actions and responses of the framework. moreover, probable predators have a vested interest in compromising the algorithm. for instance, an irrigation governance system can be manipulated by an attacker to distribute an excessive amount of water, perhaps jeopardizing the entire agricultural output due to the competitive advantage it provides. if the last structure is penetrated by attacks, the aim of integrating the ai-based dl model for water management and modern agriculture will be rendered futile. therefore, similar to intelligent systems, it is essential to integrate cyber security regulations and ensure the integrity of data access in these water management systems based on dl. to address security challenges in deep learning applications for water resource management, essential strategies encompass: implementing stringent data protection protocols, ensuring model transparency and interpretability, mitigating data privacy issues, establishing secure infrastructure, conducting regular threat assessments, and integrating feedback mechanisms for ongoing system enhancement, all while taking into account the specific context of the water management system and applicable local regulations. recent examples of deep learning applications addressing security concerns in water management encompass: employing computer vision to identify leaks and anomalies in pipelines via cctv footage, detecting potential cyberattacks on water distribution networks through the analysis of traffic patterns, predicting water quality concerns by scrutinizing sensor data, and forecasting extreme weather phenomena such as floods to proactively mitigate water security risks; all utilizing deep learning algorithms to analyze extensive datasets and discern patterns that may signify a security threat. context-aware data analysis dl primarily focuses on the design and structure of a model or architecture rather than the specific method used. the algorithms indeed require updates when the systems go to the next generation. if a deep-learning network undergoes a significant technical upgrade, the quantity of retraining needed will always be inadequate. as an illustration, we can implement intelligent sensors to assess the water quality, focusing on a limited number of global sustainability research global scientific research 65 characteristics. if this system is improved in the future, it will be necessary to retrain the deep neural networks that control the smart sensors with new parameters. undoubtedly, this task is highly challenging to improve and also characterized by its lack of predictability. retraining for intelligent or iot systems that operate with realtime data is exceedingly intricate. the fundamental challenge arises from the non-context-aware behavior of neural networks and the unknown side of their activity after training. to address challenges in context-aware data analysis within deep learning applications for water resource management, it needs to adopt strategies such as integrating spatial and temporal features, employing hybrid models that merge physics-based and data-driven methodologies, utilizing data preprocessing techniques to manage missing values and inconsistencies, and developing context-aware architectures that adapt to fluctuating environmental conditions, all while ensuring meticulous data collection, quality control, and the consideration of pertinent contextual factors such as meteorological patterns, land use, and water quality metrics. training efficiency dl networks in real-time systems undergo constant modification to accommodate changes in previously implemented methods. nonetheless, owing to the erratic characteristics of this dl structure, the modified algorithm cannot assure the same level of accuracy or optimization as the previous method under equivalent situations. the replacement of sensors may affect neuronal remodeling in neural systems, potentially altering the behavior of the entire present framework. the effectiveness of training is crucial for deep neural networks to achieve optimal performance with the necessary accuracy, even after a significant system modification. to address training efficiency challenges in deep learning applications for water resource management, essential strategies encompass: optimizing data collection and preprocessing, selecting suitable deep learning architectures according to data characteristics, employing transfer learning, applying methods to diminish computational complexity, integrating physics-based knowledge into models, and emphasizing data augmentation to enhance limited datasets; all while accounting for the specific context and constraints of the water resource management issue at hand. algorithmic development and learning system design the creation of deep learning models presents a considerable challenge in formulating an algorithm tailored to a particular issue. addressing this obstacle is essential for enabling the implementation of these models in practical water issues. when we clearly articulate the real-world water issue and delineate the training data, such as time series or image data, we can easily identify specific methodologies like supervised or unsupervised learning, regression, or classification. nonetheless, choosing a suitable technique can be difficult due to the plethora of available dl algorithms. after selecting the algorithm, the subsequent challenge is to build its architecture to enhance performance. prior to training a cnn with data, it is essential to define numerous parameters, including the input data type (1d or 2d), the number of convolutional layers, and the dimensions of the filters. manual procedures often formulate and evaluate the network architecture—a procedure that can be arduous and susceptible to errors. nevertheless, the implementation of optimization techniques can resolve this problem, referred to as the neural architecture search (nas) issue. nas, a specialized field within automated machine learning, focuses on enhancing the deployment of machine learning for practical issues. the process encompasses a complete workflow, starting with the initial raw data and concluding with the installation of the finalized model. prior studies have demonstrated that nas methodologies surpass manually crafted network architectures in several applications, particularly in computer vision. however, only a few studies focus on the global sustainability research global scientific research 66 development of cnns for algal categorization in river catchments, limiting the application of nas in water administration. additionally, it is crucial to explore the capabilities of nas in developing a mixed network, such as cnn+lstm, to address intricate water-related issues. dl facilitates the creation of a unified model to address intricate issues and promote comprehensive learning. typically, these problems encompass a sequence of tasks that conventional learning methods address. to surmount challenges in algorithmic development and learning system design for deep learning applications in water resource management, it needs to prioritize resolving data quality issues, selecting suitable architectures such as lstms for time-series data, integrating domain knowledge into feature engineering, formulating robust validation strategies, ensuring model explainability, and mitigating computational constraints through optimization techniques and cloud computing. multi-agent systems a system with several agents comprises multiple intelligent humans that engage within a shared setting to pursue either cooperative or adversarial objectives. an agent is a software entity, robotic system, or individual. each agent generally possesses unique views of the surroundings, conduct, and goals. each agent substantially engages with other agents through its actions or modifications to the communal environment. the agents may exhibit collaboration, competition, or a combination of both. multi-agent systems can efficiently oversee the dynamic interactions among various components of the uws system and the surrounding environment. these interactions become increasingly significant as the system grows more complicated and uncertain. river basins and hydrological systems extensively use agent-based models to analyze the collective behaviors of multiple agents and formulate land and water management strategies (yang et al., 2009). nonetheless, the underwater system (uws) limits the implementation of multi-agent systems, primarily emphasizing agent design and the resolution of technological obstacles. the independent choices on ideal strategy and operational issues require the deployment of cooperative multi-agent systems. when you combine different agents with advanced deep reinforcement learning technology, you can make an autonomous choice framework that can make the best decisions in real-time and adjust to a changing environment. an illustration is the formulation of a multi-agent deep reinforcement learning methodology to simultaneously optimize dissolved oxygen (do) levels and reagent dosages in wwtp. this framework can supervise the functioning of storage vessels and sustainable drainage systems (suds) within the sewage system, regulate water containers and pumps in the water distribution network, or orchestrate several drones during flood emergency operations. the system ingredients, defined as multiple people, may collaborate to attain the defined objectives. in the domain of pump operations, we can develop a specialized agent to oversee pumps in a designated section of the water network, providing optimal pressure to satisfy increased demand. an auxiliary agent can be devised to control pumps in a neighboring section of the water line in order to maintain low pressure and reduce leakage. to achieve competing strategic goals in the water system, the two operators must engage and skillfully maneuver under dynamic conditions. the implementation of multi-agent systems facilitates the creation of a decentralized, very effective underwater wireless sensor system (uws). furthermore, representatives from numerous groups, including owners, planners for cities, and water customers, have the ability to negotiate to safeguard their respective interests in the development and administration of water systems. to address the challenges of implementing deep learning in multi-agent systems for water resource management, essential strategies encompass: meticulously designing agent interactions, regulating information sharing, employing suitable reinforcement learning methodologies, formulating robust reward functions, integrating domain expertise, and ensuring scalability for intricate water systems; all while accounting for the distinctive attributes of the water resource environment and the varied stakeholders involved. global sustainability research global scientific research 67 digital twins and autonomous systems the concept of digital twins has generated considerable interest and progress in the water sector. while there are some similarities between a digital twin and a classical model, a digital twin typically integrates with the real world. ibm defines digital as a virtual embodiment of a physical system across its full lifecycle, employing real-time data to enhance understanding, learning, and reasoning. while the precise construction of a digital twin remains a topic of debate, we typically anticipate it to possess the following fundamental characteristics: we integrate the employed mathematical models with the real water system they depict, which may be based on physical principles, machine learning, or a combination of both. real-time info coming from connected sensors combines these models to accurately depict the recent condition of the physical structure. they have the ability to analyze hypothetical events and provide forecasts regarding future conditions. moreover, it may leverage design, maintenance, and operational ideas gained by digital twins to establish a connection between the digital twin and the physical system. moreover, it can consistently update the digital twin with data from the actual environment and use it in rapid calculations to enhance system competence and amenities. the advent of modern twins will significantly influence our engagement with, oversight of, and regulation of physical systems. the integration of machine learning in the expansion of digital twins within the water sector is markedly insufficient. in our expertise, all recorded cases of digital twins have depended on physically based simulations, but a limited number have employed machine learning to enhance the efficacy of hydraulic models, such as forecasting pump speeds or assessing their impact on wwtps. the dl algorithms discussed in section 3 can significantly impact digital twins, facilitating autonomous operation by automating tasks. ml is a fruitful innovation that can enhance our knowledge of mechanical structures and offer closure to optimize their performances. the progression of ai can deliver a more profound comprehension of the mechanisms within a system. physics-informed ml is a burgeoning investigation domain that leverages system data to develop ml models that are more accurate and flexible. hydrology and water quality have effectively used this methodology, and it has the potential to create digital twins for urban water systems. to address challenges in deploying deep learning applications in digital twins and autonomous systems for water resource management, it needs to prioritize data quality, model complexity, real-time feedback loops, infrastructure compatibility, robust data pipelines, and the ethical and societal implications while utilizing advanced methodologies such as transfer learning, explainable ai, and federated learning to improve model performance and reliability. conclusions the world's efforts to protect and conserve water are positively impacted by technological advancements like water consumption forecasting, leak detection and localization, sewage problem and blockage identification, cyber security and resource evaluation, wastewater recycling and administration, water safety estimation, rainwater management, and irrigation oversight. the application of ai technologies, particularly deep learning, provides a strategic framework for the prospective preservation of water supplies. the suggested research delivers significant thoughts into the adoption of deep neural network models in water management. it underscores the importance and relevance of these models in diverse water management practices. this paper investigates the obstacles and potential related to the execution of deep neural networks in water management. these encompass algorithmic development, multi-agent operations, digital twins, data quality and accessibility, security, context-aware data analysis, and training efficacy. consequently, the proposed study provides direction for forthcoming research initiatives by emphasizing challenges and outstanding issues in water management through deep neural networks. stakeholders in the water management sector aiming to incorporate global sustainability research global scientific research 68 dl technologies should identify pertinent use cases, establish a robust data foundation, collaborate with data scientists and specialists, initiate pilot projects with a limited scope, prioritize data quality and accessibility, ensure stakeholder engagement, and cultivate a culture of continuous learning and adaptation to maximize the potential of dl in water management systems. declaration

miebi gbigbi1*, christiana ojirhevwe2 1department of agricultural economics, delta state university abraka, delta state, nigeria corresponding author: theophilus miebi gbigbi. email: gbigbitheophilusmiebi@yahoo.com received: 21 november, 2024, accepted: 11 march, 2025, published: 20 march, 2025 abstract this research investigates the role of insurance services and their impact on income shocks among poultry farmers in delta state, nigeria. it uses a multistage sampling method to select 150 respondents surveyed through a questionnaire. the data gathered were analyzed using descriptive statistics and inferential statistics. the average age of the farmers was 46 years. the majority of the respondents were male, married, and well-educated. the average family size was seven people. on average, respondents possessed eight years of experience in farming. the average flock size was 887 birds. the binary logit analysis revealed that flock size, awareness of insurance, attitude towards insurance, premium payment, access to credit, and occupation greatly influenced the utilization of insurance services at a 5% level of significance. the insurance services used by the poultry farmers included extension services, veterinary services, general risk coverage, and training programs designed for farmers. the primary constraints faced by poultry farmers were inadequate awareness about insurance benefits, difficulties in implementing insurance policies, and delays in the payment of indemnity (compensation). provision of premium subsidies (pps), insurance coverage of equipment (icoe), timely payment of indemnity (poi), encouragement of institutional lenders (eil), and training programs for farmers (tof) assist in absorbing income shocks among poultry farmers. the study recommends needing improved awareness and enhanced collaboration between farmers and insurance providers to increase the effectiveness of insurance in protecting farmers' incomes. keywords: poultry farmers; utilization; insurance services; output; income shock introduction poultry production plays a fundamental role in nigeria’s agricultural sector, significantly contributing to economic development, food security, and poverty reduction, particularly in rural areas where agriculture remains central to daily sustenance and income generation. as one of the highest-yielding sectors in the agricultural industry, poultry farming provides quick financial returns, contributing to food availability and diversification of livelihoods for many rural nigerians (omondi, 2022; yeboah, 2022). the importance of poultry farming in nigeria is underscored by its ability to address the nutritional needs of the population, specifically by increasing protein intake, and its capacity to generate income for families, contributing directly to poverty alleviation (omonona et al., 2023). additionally, poultry farming is an attractive business opportunity due to its low entry barrier compared to other global sustainability research global scientific research 2 forms of livestock production, making it accessible to a wide range of farmers, especially those in rural communities (offiah et al., 2024). the poultry industry in nigeria is vast, encompassing small-scale, mediumscale, and large-scale enterprises, with a majority of poultry farmers operating on smallholder levels. smallholder poultry farming is a crucial livelihood activity in many rural areas, where it serves as an important source of household income and nutritional security. medium and large-scale commercial poultry farms, on the other hand, contribute significantly to employment generation, value chain development, and economic growth by supplying poultry products to both local and international markets (udoye et al., 2024). the sector comprises layers, broilers, and indigenous poultry breeds, each with its unique production characteristics and market demands. layer production provides a steady supply of eggs, which are a critical protein source, while broiler farming ensures the availability of poultry meat for consumption (bist et al. 2024). indigenous poultry farming, though often practiced at a subsistence level, is gaining recognition due to its adaptability to local environmental conditions and resilience to diseases (yusuf et al., 2024). despite its potential, poultry production is fraught with various challenges that threaten its sustainability and profitability. the sector is vulnerable to both environmental and socioeconomic risks that disrupt production cycles and undermine farmers' efforts. natural hazards such as extreme weather conditions, floods, droughts, and disease outbreaks can severely affect poultry productivity, leading to substantial losses (aliyu et al., 2023; ojogbane & gbigbi, 2022). poultry diseases such as newcastle disease, avian influenza, and coccidiosis are major concerns that require effective biosecurity measures, vaccination programs, and veterinary interventions (adesola et al., 2024). additionally, risks such as fire, theft, and other unforeseen events add layers of vulnerability, with many of these challenges beyond the control of individual farmers. these constraints can prevent farmers from reaching their production targets and destabilize the poultry industry (gbigbi, 2020). economic constraints further exacerbate the challenges in poultry farming. rising feed costs, which account for nearly 70% of production expenses, are a major hurdle for poultry farmers (ogunleye et al., 2024). the high cost of maize and soybean, which are primary ingredients in poultry feed, often leads to increased production costs and reduced profit margins. additionally, limited access to credit facilities hinders the ability of smallholder farmers to invest in improved production technologies, expand their businesses, or cushion against financial losses (gbigbi & isiorhovoja). the lack of adequate storage facilities and market access further limits profitability, forcing many farmers to sell their products at unfavorable prices during peak production periods (mukaila, 2024). in response to these challenges, the nigerian government has taken steps to mitigate risks through the nigerian agricultural insurance scheme (nais), which was established alongside the nigerian agricultural insurance corporation (naic) in 1987. this initiative provides a structured framework for insurance coverage that aims to protect farmers, including those in the poultry sector, from the financial repercussions of various disasters and uncertainties (aliyu et al., 2023). the nais is part of a broader national disaster management strategy that aims to stabilize farmers’ income, safeguard investments, and ensure continuity in agricultural production amidst unpredictable challenges (udoh et al., 2024). these insurance schemes are crucial for enhancing the resilience of farmers against risks and providing them with the financial tools needed to sustain their operations in the face of adversity. furthermore, recent updates to the nais have incorporated new technologies and improved outreach programs to increase its accessibility, especially to smallholder poultry farmers (aremu & amos 2024). digital platforms and mobile-based insurance solutions have been introduced to simplify claim processes, improve transparency, and enhance farmer participation in agricultural insurance programs (rudramuni, 2024). beyond government initiatives, private sector participation in agricultural insurance has also grown, with financial institutions and microfinance organizations developing tailor-made insurance products to support poultry farmers (ashoro et al., 2024). collaborations between insurance companies, research institutions, and extension services have played a role in educating farmers on risk management strategies and the benefits of insurance coverage. the integration of climate-smart agricultural practices, improved biosecurity measures, and better disease surveillance global sustainability research global scientific research 3 systems are also key in ensuring the long-term sustainability of poultry farming in nigeria (ngongolo & mrimi, 2024). overall, poultry farming remains a cornerstone of nigeria's agricultural sector, offering numerous opportunities for economic growth, job creation, and food security. however, persistent risks and constraints necessitate proactive measures to safeguard farmers against financial losses and production disruptions. strengthening agricultural insurance schemes, improving access to credit, investing in disease control strategies, and enhancing market access are critical steps towards ensuring a resilient and sustainable poultry industry in nigeria. the collaboration between government, private sector stakeholders, and international development agencies will be essential in addressing these challenges and maximizing the full potential of poultry farming as a viable agricultural enterprise. the findings from this research may provide valuable insights for policymakers aiming to refine agricultural insurance frameworks. enhanced policy structures could assist in reducing income volatility, promoting greater investment in agricultural sectors, and finally enabling farmers to better manage income shocks and uncertainties. by customizing insurance services to meet the specific requirements of the agricultural community, particularly within vulnerable sectors such as poultry farming, policymakers can aid in the development of a more resilient and sustainable agricultural system in nigeria. the primary objective was to evaluate the utilization of insurance services and income shocks among poultry farmers in delta state. the explicit intentions were to identify the demographic features of poultry farmers; the degree of farmers' utilization of agricultural insurance services; the factors that influence farmers' decisions to use insurance services on their farms; the existing problems, including poor linkage between poultry producers and insurance service personnel, which hinder the effective utilization of insurance services and determine the influence of insurance services on income shocks. the hypotheses were; insurance services do not relate with income shocks of poultry farmers and socioeconomic characteristics of poultry producers has no association with utilization of insurance services. the structure and organization of the paper includes the following sections: literature review (comprising conceptual framework, theoretical framework, and empirical review), methodology (including study area, research design, population and sampling, data collection methods, and analytical techniques), results and discussion, and finally, conclusion and recommendations. literature review agricultural insurance has become an essential tool for managing the fundamental risks faced by poultry farmers. by minimizing financial exposure to losses caused by natural and human-induced risks, insurance coverage enables farmers to maintain a more stable income, thereby enhancing both market stability and national food security. the role of agricultural insurance extends beyond individual risk management to broader economic benefits, as it encourages investment in improved production technologies and expansion of poultry enterprises. research has shown that when farmers have access to well-structured insurance schemes, they are more likely to adopt advanced production methods, such as high-yield breeds, improved feeding strategies, and disease prevention techniques (ologbon et al., 2021; ajemunigbohun & abdul-azeez, 2023; mfulwane, 2023). the security provided by insurance fosters long-term planning and financial stability, ensuring that poultry production remains resilient against external shocks, including climatic and economic fluctuations (madaki et al., 2024). insurance serves as a vital mechanism for mitigating income shocks experienced by poultry farmers, particularly in areas where agriculture is predominantly vulnerable to climate changes, market fluctuations, and disease outbreaks. the implementation of agricultural insurance programs spans globally and varies in effectiveness. in developed countries, such as the united states, canada, and australia, government-supported agricultural insurance schemes offer comprehensive coverage to farmers, ensuring that production-related risks do not global sustainability research global scientific research 4 culminate in financial ruin (ruan et al., 2024). these schemes typically involve subsidies that enable farmers to afford the necessary insurance premiums while still maintaining economic viability (lan et al., 2024). for instance, government subsidies serve as financial incentives that significantly influence farmers’ decisions to participate in such insurance programs, highlighting the importance of effective policy frameworks (udoh et al., 2024). conversely, in developing nations, poultry farmers frequently encounter obstacles that hinder access to sufficient risk protection, including low levels of insurance penetration, prohibitive costs, and suboptimal policy frameworks (osorio et al., 2024). research indicates that the challenges faced by smallholder farmers in countries like tanzania and vietnam primarily stem from the lack of awareness regarding available insurance options, high premiums, and bureaucratic hurdles associated with indemnity claims (mushi et al., 2024; goyal & gulati, 2024). the limited implementation of crop insurance schemes in such regions fails to provide adequate protection against the diverse risks associated with poultry farming, such as disease outbreaks and sudden market changes, thereby undermining the financial stability of these farmers (oben et al., 2024). the utilization of insurance services is a crucial factor in mitigating income shocks among poultry farmers, particularly in the context of agricultural instability caused by climate variability, market dynamics, and disease outbreaks. recent literature highlights the varied experiences and perceptions of poultry farmers regarding agricultural insurance, its impacts on operational decisions, and income stability. studies demonstrate that access to agricultural insurance can significantly decrease the vulnerability of poultry farmers to income fluctuations caused by adverse events. for example, farmers with insurance are more likely to invest in higher-quality inputs and adopt modern farming techniques, which, in turn, may lead to increased productivity and stable income streams mishra & singh (2024). moreover, insurance functions as a form of collateral that enhances farmers' credibility when seeking loans, thereby improving access to financial resources critical for sustainable farming practices (vihi et al., 2024). this symbiotic relationship between insurance participation and financial accessibility is essential for fostering resilience in the poultry sector. furthermore, the agricultural insurance landscape reflects broader economic vulnerabilities and the critical need for government intervention to support the agriculture sector. in settings where resources are scarce, governments play a pivotal role in implementing effective agricultural insurance policies that not only stabilize income but also bolster overall food security and rural development (xie et al., 2024). the strategic integration of technology, as discussed in recent literature, can also enhance the effectiveness of insurance by facilitating better risk assessment and management practices, making it easier for farmers to engage with insurance products (mushi et al., 2025). research conducted by kipkemoi and ceyhan (2021), nepali (2021), and nwobodo et al. (2023) indicates that many farmers have a limited understanding of insurance processes. this lack of knowledge results in decreased participation, as farmers who do adopt insurance frequently fail to seek clarifications regarding policy terms, coverage specifics, and claims procedures, thereby diminishing the effectiveness of the insurance they receive. in africa, the adoption of agricultural insurance remains notably low despite its significant potential to protect farmers against economic shocks. studies indicate that insurance can stabilize farmers' incomes amidst unpredictable weather conditions, disease outbreaks, and volatile market prices, essential factors affecting agricultural productivity and sustainability in the region (osorio et al., 2024; qin et al., 2024). countries such as kenya, south africa, and ghana have pioneered index-based insurance programs designed to align with local agricultural risks, utilizing technological advances to enhance access and affordability for farmers (qin et al., 2024). nevertheless, many smallholder poultry farmers in sub-saharan africa remain marginalized from these vital services. key barriers include insufficient financial literacy, skepticism towards insurance providers, and logistical issues surrounding premium payments and claims processing (su et al., 2024). to tackle these challenges, comprehensive policy reforms and greater government intervention are necessary to design inclusive insurance models that effectively cater to the most vulnerable agricultural producers. global sustainability research global scientific research 5 in nigeria, poultry farming is a fundamental component of rural livelihoods and national food security; however, the sector is highly exposed to income shocks due to disease outbreaks, fluctuations in feed prices, theft, and environmental threats (gyamerah & owusu, 2024). conversely, the adoption of insurance among poultry farmers in developing countries presents unique challenges. high premiums, limited awareness of available products, and inadequate infrastructure often hinder effective participation in these insurance schemes (udoh et al., 2024; ifabiyi et al., 2024). research indicates that many farmers lack trust in insurance providers, stemming from past experiences with delayed claim payouts and unclear policy terms (lan et al., 2024). this distrust further complicates farmers’ willingness to engage with insurance products, which could otherwise safeguard their livelihoods against unpredictable agricultural risks (ifabiyi et al., 2024). furthermore, the effectiveness of insurance services is often mediated by government interventions and subsidy programs that aim to enhance the sustainability of agricultural practices (lan et al., 2024; osorio et al., 2024). for instance, when governmentbacked insurance products align with farmer education initiatives about risk management, the likelihood of insurance uptake increases significantly. therefore, the role of institutional frameworks is critical in shaping farmers' perceptions and ultimately their willingness to utilize agricultural insurance (mushi et al., 2024). misinterpretations concerning the extent and protection provided by insurance policies can result in misconceptions, which may lead to confusion, particularly during crises or when claims need to be submitted. this paper emphasizes the important role of agricultural insurance in protecting farmers from potential financial hardships resulting from unforeseen situations. safeguarding poultry farmers from such risks is essential not only for their personal financial well-being but also for ensuring consistent food production to meet the dietary needs of the population. however, as noted by alam et al. (2020), akbarovich (2020), and madaki et al. (2023). the establishment of the nigerian agricultural insurance corporation (naic) aimed to offer tailored insurance solutions for farmers, including those in poultry production (muhammad & inusa 2024). despite this initiative, the uptake of agricultural insurance among nigerian poultry farmers remains disappointingly low. factors contributing to this trend include limited awareness of available options, perceived exorbitant premium costs, and convoluted claim processes (lan et al., 2024). studies suggest that despite several initiatives, the ongoing barriers to insurance adoption among poultry farmers continue to demand attention (shkembi et al., 2024). furthermore, research has highlighted that integrating mobile technology into agricultural insurance schemes could significantly enhance accessibility and participation rates among farmers (samota et al., 2024). mobile insurance services can facilitate streamlined premium payments, simplify the claims process, and foster improved communication between farmers and insurers, thereby enhancing trust in the insurance framework. the advantages of agricultural insurance extend beyond mere risk management; they also improve farmers' access to credit and essential financial resources. financial institutions are more inclined to extend credit to insured farmers, as the associated risks for lenders decrease appreciably when coverage is in place (raharjanti et al., 2024). this enhanced access allows poultry farmers to scale their operations, invest in upgraded infrastructure, and consequently boost productivity. studies reveal that smallholder poultry farmers engaged in insurance programs are more likely to secure funding for various farm improvements, thus fostering increased profitability and economic growth within the sector (khanal et al., 2024). this cycle positively influences rural economic development and job creation, as expanded poultry farming operations generate employment opportunities not just for farmhands but also for feed suppliers, veterinary service providers, and other agricultural stakeholders (mishra & singh, 2024). recent investigations point to the transformative potential of digital innovations and mobile-based insurance services in bolstering insurance adoption among poultry farmers (johari et al., 2024). the launch of mobile insurance platforms and digital claim processes has enhanced accessibility, making it simpler for farmers to enroll in insurance schemes and submit claims without facing excessive bureaucratic hurdles. moreover, mobile global sustainability research global scientific research 6 technology facilitates real-time communication with insurers, thereby narrowing the information gap and fostering transparency in insurance dealings. policymakers and relevant stakeholders in agriculture should harness these technological advancements to develop more inclusive insurance frameworks tailored to the specific needs of smallholder poultry farmers, ensuring their inclusion in the financial protection ecosystem (kumar, 2024). strengthening agricultural insurance policies will ultimately contribute to national economic stability and reaffirm poultry farming's significance in enhancing the broader agricultural landscape (preethi & sasane, 2024). this research is based on the following theories: risk aversion and utility maximization theory in poultry farming poultry farming is inherently fraught with considerable risks, including disease outbreaks, feed price volatility, and market fluctuations. utility maximization theory posits that individuals strive to maximize their expected utility, leading risk-averse farmers to implement strategies that stabilize their income. specifically, insurance acts as a risk-transfer mechanism, allowing these farmers to mitigate financial losses associated with adverse events. the degree of risk aversion, therefore, becomes a pivotal determinant in the decision to utilize insurance services. research shows that farmers who display heightened risk aversion are more inclined to secure insurance coverage to guard against potential income shocks (waithaka, 2024; guan et al., 2024). empirical studies substantiate this theoretical framework. a recent investigation of poultry farmers in nigeria confirmed that risk perception significantly influenced insurance adoption. farmers who regarded their operations as riskier were more likely to insure (shah, 2024). this behavior aligns with the utility maximization concept, wherein risk-averse individuals prioritize securing their expected utility against possible adversities. moreover, income variability resulting from unpredictable events can cause severe welfare losses for risk-averse farmers. through purchasing insurance, these farmers can stabilize their incomes, safeguarding their consumption patterns and investment capabilities, which are crucial for maintaining productivity and resilience against future shocks (waithaka, 2024; guan et al., 2024). however, the decision to purchase insurance is also contingent upon the perceived effectiveness and reliability of the insurance products available. farmers’ skepticism about insurers' credibility or fears regarding timely compensation can hinder insurance uptake, even among risk-averse individuals. establishing trust between insurers and farmers is essential for increasing the adoption of insurance services (bourova et al., 2024). in summary, the interplay of risk aversion and utility maximization theory intricately informs poultry farmers' decisions regarding insurance services, highlighting the importance of income stabilization while underscoring the need for trustworthy insurance products. information asymmetry and awareness information asymmetry arises when one party possesses superior information, hindering optimal decision-making. in the context of poultry farmers and insurance uptake, inadequate awareness of insurance products plays a critical role in limiting adoption rates. a study conducted in southwest nigeria revealed that while a significant majority (59.6%) of poultry farmers were aware of livestock insurance policies, only 11.9% actually insured their farms, illustrating the vast gap between awareness and utilization attributable to information asymmetry (guan et al., 2024). farmers may know about available insurance options but often lack comprehensive knowledge concerning their benefits, specifics of coverage, and the claims process, leading to hesitance in engaging with these products. misconceptions and mistrust stemming from previous adverse experiences or anecdotal reports further aggravate this issue. farmers who have encountered delays in claims or claim denials may develop skepticism toward insurance, thereby further distancing themselves from insurance services. this trust deficit is commonly global sustainability research global scientific research 7 exacerbated by a lack of clear communication from insurers, reinforcing information asymmetry (waithaka, 2024; guan et al., 2024). addressing these challenges demands targeted educational programs and effective communication strategies, where extension services and agricultural advisors can provide unbiased and comprehensive information about insurance products and assist farmers with the enrollment process. technological advancements also present opportunities to bridge this information gap. for instance, mobile platforms and digital applications can expand access to insurance information and services, enhancing the overall adoption landscape (osorio et al., 2024). in regions where mobile-based insurance initiatives have been launched, farmers can easily learn about, purchase, and claim insurance via their smartphones, simplifying the process and bolstering participation. thus, combating information asymmetry through targeted education, transparent communication, and technological solutions is vital for improving insurance utilization among poultry farmers. financial constraints and liquidity theory financial constraints significantly shape a poultry farmer’s capacity to afford insurance premiums, even when the advantages of such coverage are clear. liquidity preference theory suggests that individuals prioritize immediate financial needs, often resulting in farmers allocating their limited resources to more pressing operational expenses instead of insurance premiums. recent research highlights that financial limitations remain a formidable barrier to insurance adoption. in a study of poultry farmers in south bengal, for instance, low participation in livestock insurance was largely attributed to insufficient financial resources (liu et al., 2024). furthermore, the perceived opportunity cost of paying insurance premiums can deter farmers from acquiring coverage. the funds that could be allocated for insurance are often redirected towards necessary inputs like feed and labor, particularly given the small profit margins prevalent in poultry farming. these dynamics reveal that when farmers operate with limited financial flexibility, they are less inclined to invest in insurance (guan et al., 2024). addressing financial barriers can be facilitated through various strategies, including subsidizing insurance premiums as seen in governmentbacked agricultural insurance schemes globally (amalia & arifin, 2024). additionally, microinsurance models designed for smallholder farmers can offer lower premiums and flexible payment structures, thereby making insurance more accessible. moreover, integrating insurance with credit facilities can enhance affordability. for instance, bundling insurance with agricultural loans ensures that farmers can obtain coverage without having to make separate premium payments. such strategies have demonstrated success in nigeria through initiatives like the nigeria incentive-based risk sharing system for agricultural lending (nirsal) (amalia & arifin, 2024). consequently, financial constraints stand as a major determinant of insurance utilization, underscoring the necessity for strategic interventions aimed at alleviating the economic burdens on poultry farmers. behavioral economics and perception of risk behavioral economics provides critical insights into how poultry farmers approach decisions regarding insurance services, challenging the assumption of rational decision-making found in classical economic models. one pertinent concept is prospect theory, which posits that individuals perceive potential losses with greater weight than equivalent gains. in the sphere of insurance, farmers may undervalue the advantages of insurance due to a focus on the guaranteed costs of premiums instead of the uncertain prospects of receiving payouts, thus exhibiting loss aversion that deters them from purchasing coverage (shah, 2024; liu et al., 2024). another behavioral aspect influencing these decisions is present bias, where immediate financial needs often take precedence over future uncertainties. particularly in the context of poultry farming, which is characterized by seasonality and periodic cash flow constraints, farmers might prioritize investments in immediate needs (e.g., feed or equipment) over global sustainability research global scientific research 8 insurance, which only provides benefits in adverse situations (amalia & arifin, 2024). empirical evidence corroborates these behavioral insights. a study in uganda revealed that, despite offering subsidized insurance rates, participation remained low due to low perceived risk and mistrust toward insurance providers (cha et al., 2024). to counteract these behavioral biases, tailored interventions such as behavioral nudges can be employed. this includes reframing insurance as an investment rather than a mere expense and utilizing default enrollment mechanisms to increase participation in insurance programs (amalia & arifin, 2024). additionally, providing flexible payment structures and leveraging digital tools for reminders about policy renewals can further encourage uptake. institutional trust and policy environment the significance of institutional trust and government policy in influencing insurance adoption among poultry farmers is substantial. trust in insurers, financial institutions, and regulatory bodies is a crucial determinant of whether farmers perceive insurance as a reliable safety net. negative past experiences, including delays in claim payouts and convoluted documentation processes, contribute to a lack of trust, thereby deterring farmers from engaging with formal insurance providers (waithaka, 2024; muraya et al., 2024). to foster greater trust and facilitate insurance adoption, government interventions can play a pivotal role. strengthening regulatory oversight, ensuring transparency in insurance policies, and collaborating with private insurers to provide subsidized agricultural insurance are effective strategies to expand coverage and enhance farmer confidence in these offerings (osorio et al., 2024; amalia & arifin, 2024). additionally, conditioning discounts on insurance premiums for farmers who adopt best management practices can further incentivize uptake. methodology the research was carried out in the delta north agricultural zone of delta state, nigeria, which is a region predominantly dedicated to the cultivation of arable crops and poultry farming, along with some participation in plantation agriculture. a multistage sampling method was used to select respondents for this research. in the initial stage, 50% of the local government areas (lgas) within the agricultural zone were chosen, leading to the inclusion of five lgas. in the subsequent stage, three farming communities were randomly selected from each chosen lga, resulting in a total of 15 agrarian villages. in the third stage, a random selection of 12 respondents was made from each community, producing an initial sample size of 180 producers. data was gathered using a structured questionnaire as the main tool. to guarantee accurate data collection, trained enumerators who were skilled in both english and the respondents’ local language administered the questionnaires. however, 30 questionnaires were discarded due to incomplete information, leading to a final sample size of 150 respondents for analysis. analytical techniques data collected were evaluated using descriptive and inferential statistics. descriptive statistics was used to achieve specific objectives (i), (iii), and (iv). descriptive statistics typically involve summarizing and describing the main features of a dataset. in your case, it seems like you used a likert-type scale with three categories (highly utilized = 3, moderately utilized = 2, not utilized = 0) and calculated means for these categories to describe certain aspects of your data. a logit model to achieve objective (ii). a logit model is often used in logistic regression to analyze global sustainability research global scientific research 9 binary or categorical outcomes. it's used when you want to predict the probability of an event occurring based on certain predictor variables. objective (v) was realized using a multiple regression model. multiple regression is used to analyze the relationship between a dependent variable and multiple independent variables. it helps you understand how different variables may be related to each other. model specification of logit

discussions socioeconomic characteristics of respondents the socioeconomic characteristics of the respondents are presented in table 1. gender distribution the results of the examination indicate an important gender imbalance within the poultry sector, with 72% of participants being male and merely 28% female as seen in table 1. this demographic breakdown emphasizes the fact that the poultry industry is primarily male-dominated. this pattern is not a unique phenomenon, as earlier investigations conducted by nwachukwu et al (2021) and aminu & hermanns (2021) have also recognized a similar predominance of male poultry farmers. gaining insight into the factors contributing to this gender disparity is essential for understanding the dynamics within the poultry farming industry. one potential reason for the detected gender imbalance in poultry farming is the challenging nature of the occupation. poultry farming encompasses various physically intensive tasks, including but not limited to feeding, cleaning, and ensuring the well-being of the birds. the strict and labour-intensive characteristics of these tasks may deter female involvement in the industry. societal views and conventional gender roles may also shape the workforce composition in poultry farming, with the perception that such physically strenuous work is more appropriate for men. in addition, cultural and economic elements may contribute to perpetuating the gender divide in poultry farming. societal norms and expectations regarding women's responsibilities in agriculture and animal husbandry may affect vocational choices, pushing women away from poultry farming. limited access to resources, such as financing and land, which are often essential for initiating and maintaining a poultry enterprise, may disproportionately impact women, further exacerbating their underrepresentation in this field. tackling the gender disparity in poultry farming is critical not only for ensuring fairness but also for the practical sustainability and development of the industry. acknowledging the potential roles of women in poultry farming and adopting strategies to promote gender inclusivity could result in a more varied and strong poultry sector. policymakers, industry stakeholders, and advocacy organizations can collaborate to cultivate an environment that promotes and assists the active engagement of women in poultry farming by addressing the socio-economic and cultural impediments that may restrict their participation. age of respondent the demographic profile of poultry ranchers is essential for comprehending the dynamics of the poultry farming industry. the information that most (80%) poultry ranchers are aged between 37 and 56 years, with an average age of 46, has major implications for the current and future environment of the industry. this demographic trend indicates a concentration of relatively young individuals in their productive years who are involved in poultry farming. a primary implication of having a majority of poultry ranchers in this age group is the potential for increased resilience and adaptability within the industry. individuals in this age range typically possess a combination of energy, enthusiasm, and experience, which are important qualities for effectively managing the challenges encountered in poultry farming. their youthfulness may lead to a proactive stance in welcoming new technologies, implementing innovative farming strategies, and adjusting to changing market trends. this is advantageous for the overall sustainability and competitiveness of the poultry farming sector. comparisons made with a study conducted by popoola & obi-egbedi (2020) that reported global sustainability research global scientific research 11 a similar age distribution among farmers lend credence to the current findings. the consistency across studies implies that the age profile of poultry ranchers may demonstrate stability over time. this stability can be beneficial for policymakers, researchers, and industry stakeholders in developing targeted interventions, policies, and support systems that cater to the unique needs and characteristics of this demographic group. besides, the age distribution prompts inquiries about succession planning within poultry farming enterprises. as these farmers age, it becomes critical to consider the effective transfer of knowledge, skills, and operations to the next generation. it is essential for the industry to cultivate an environment that encourages and assists the entry of younger individuals into poultry farming, ensuring a smooth transition and ongoing growth of the sector. marital status the result reveal that 76% of the participants in the study were married, while 10% were single, another 10% were widowed, and 2% were divorced, offering important insights into the demographic makeup of poultry farmers within the surveyed group. this observation is consistent with the research conducted by onyemekihian et al (2023) and michael et al (2022), who asserted that a important proportion of poultry farmers are indeed married individuals. one possible explanation for this trend is that married individuals might be regarded as more responsible and driven to participate in poultry farming. the relationship between marital status and involvement in poultry farming can be complex. marriage typically brings additional responsibilities, such as providing for a family and ensuring financial stability. engaging in poultry farming can be seen as a strategic approach for these individuals to enhance their economic well-being and improve their overall quality of life. the sense of responsibility linked to marriage may also extend to the dedication required in poultry farming. operating a poultry farm necessitates commitment, consistent effort, and a long-term vision. married individuals, motivated by family obligations, may perceive poultry farming as a feasible and sustainable source of income, thus accounting for the notable proportion in this demographic. that being apart, the cultural and societal expectations placed on married individuals to secure a reliable source of income for their families could are a motivating factor. poultry farming, with its potential for profitability and economic sustainability, may be particularly attractive to married individuals striving to meet these expectations. educational status the data indicates that a substantial portion (56%) of poultry ranchers possess post-primary education, with 38% attaining tertiary education and merely 6% having completed only primary education. this information provides valuable insights into the educational qualifications of those involved in poultry farming. this distribution implies that a majority of poultry ranchers have attained a higher level of education, which could considerably influence the overall management and success of their poultry enterprises. a noteworthy aspect of this finding is the potential positive impact of education on poultry ranchers' ability to access and understand information pertinent to effective risk management. higher levels of education are often linked with improved analytical and decision-making capabilities, alongside an enhanced ability to comprehend and adapt to variable challenges. in poultry farming, where various risks, such as disease outbreaks, market variations, and environmental factors, can affect operations, having a well-educated workforce could lead to more knowledgeable and strategic decision-making. the consistency of this result with prior research, such as the study conducted by sani et al (2023), further emphasizes the significance of education within agribusiness. they put additional emphasis on the benefits of education in agriculture and related domains, illustrating how it can enhance the efficiency, productivity, and overall sustainability of agricultural practices. the correlation identified in the present study emphasizes the persistence global sustainability research global scientific research 12 of this trend, emphasizing the lasting importance of education considering poultry ranching. moreover, the findings may imply that individuals with post-primary and tertiary education are more inclined to engage in poultry farming as a business effort rather than as a means of subsistence. this could have wider implications for the poultry sector, indicating a shift towards a more professionalized and commercially-driven model of poultry farming. the potential integration of advanced technologies, data-driven decision-making, and best practices in poultry management may be more attainable for individuals with higher educational qualifications. farming experience the result as presented in table 1 indicates that a majority (64%) of participants possess 6-10 years of farming experience, with an average duration of 8 years, which represents an important observation that has implications for the comprehension and enhancement of poultry farming practices. the existence of 6-10 years of farming experience among respondents is remarkable. this range signifies a substantial degree of dedication and commitment to the field of poultry farming. the fact that a considerable majority falls within this range indicates a veteran group of individuals who have dedicated an important portion of their time and effort to refining their skills in poultry farming. this accumulation of experience is likely to encourage a deeper comprehension of the complexities associated with poultry farming, including breeding, nutrition, disease management, and overall farm management. the average duration of 8 years of farming experience further stresses the solid foundation of knowledge and expertise that the respondents contribute. engagement in poultry farming for eight years signifies a considerable timeframe in which individuals encounter various challenges, successes, and opportunities for learning. this type of practical experience is invaluable, as it equips farmers with a refined understanding of the sector, enabling them to make well-knowledgeable decisions and apply effective strategies. gbigbi (2021) has previously emphasized the importance of experience in farming, which corroborates the current findings. their emphasis on the importance of experience aligns with the acknowledgment that practical knowledge gained over years of farming is a critical component for achieving success and sustainability in agricultural pursuits. the details of poultry farming, such as disease prevention, optimal feeding practices, and efficient production methods, often require a level of skill that can solely be attained through years of hands-on experience. the implications of this finding extend beyond individual farms to the wider poultry farming sector. a group of farmers possessing 6-10 years of experience, on average, can enhance the collective knowledge base of the industry. this shared expertise may promote collaboration and information exchange, leading to continuous enhancement in farming practices, increased productivity, and the development of innovative approaches to common challenges. besides, the findings carry significance for policy and support programs within the agricultural sector. acknowledging the importance of experience in poultry farming should motivate policymakers and stakeholders to devise programs that nurture and assist the ongoing professional growth of farmers. this could encompass training programs, mentorship opportunities, and knowledge-sharing platforms that promote the transfer of experience from seasoned farmers to those who are newer to the industry. family size the findings indicate that the majority of respondents (52%) had family sizes ranging from six to ten individuals, yielding a mean family size of seven individuals as seen in table 1. this observation offers valuable insights into the demographics of poultry ranchers and their households. this result suggests a prevailing trend among poultry ranchers towards larger family units, which can have major implications for their farming activities. the recorded mean family size of seven individuals is noteworthy, as it corresponds with the research conducted by gbigbi and global sustainability research global scientific research 13 ikechukwuka (2020), who documented a similar mean household size in their investigation. the consistency of findings across various studies enhances the credibility and applicability of the results. it indicates that the trend of larger household sizes among poultry ranchers is not an isolated occurrence but rather a wider trend that may be influenced by several socio-economic and cultural factors. one possible rationale for the larger family sizes among poultry ranchers could be the necessity for sufficient family labour to support the demanding nature of farming activities, especially in the poultry sector. poultry farming frequently requires considerable manual labour for tasks such as feeding, cleaning, and maintaining the facilities. larger family sizes may provide poultry ranchers with a readily available and cost-efficient source of labour, thereby contributing to the efficiency and sustainability of their operations. besides, the finding holds implications for comprehending the social dynamics within poultry farming communities. larger families may cultivate a sense of community and shared responsibility, thereby creating a supportive network for poultry ranchers. this social cohesion could enhance knowledge exchange, resource sharing, and mutual assistance, further bolstering the resilience of the poultry farming community. nonetheless, it is essential to identify possible challenges related to larger family sizes, such as heightened financial pressure on households and the importance of effective management of family dynamics within the farming operation. achieving a balance between the benefits of having a larger family for farm labour and the challenges it may pose is essential for the long-term sustainability of poultry farming enterprises. farm size the findings of the research demonstrate that 76% of poultry producers operate at a modest scale, with a poultry flock size ranging from 250 to 1,149 birds, and an average flock size of 887 birds (table 1). these results provide major insights into the current characteristics of the poultry farming sector. the dominance of small-scale chicken farming suggests that a considerable portion of the poultry industry comprises relatively smaller enterprises. this inference aligns with the study by ogba et al (2020) concerning the challenges experienced by small poultry farms in abia state. this has ramifications for various facets of the industry, encompassing production efficiency, market dynamics, and the socio-economic context of chicken farming. understanding the presence of small-scale operations is critical for policymakers, agricultural organizations, and researchers aiming to devise focused interventions and support systems for this group of farmers. a major consequence of the small-scale nature of the majority of chicken farms is the potential effect on production efficiency. smaller flock sizes may indicatively reveal limited resources and infrastructure, which could affect economies of scale. farmers functioning at this scale may encounter obstacles in integrating state-of-the-art technologies, executing efficient management practices, and negotiating beneficial terms with suppliers. tackling these obstacles could improve the overall productivity and sustainability of small-scale chicken farming enterprises. besides, the average flock size of 887 birds is a benchmark for discerning the standard scale of small chicken farms. examining the elements that contribute to this average, such as regional differences, resource availability, and market demands, can provide insightful perspectives. for example, certain regions may exhibit a greater occurrence of small-scale farming due to geographical limitations or cultural practices, while others may feature larger operations propelled by market requirements. similarly, the study's outcomes may simplify the economic and social ramifications for farmers engaged at this scale. small-scale farmers might face distinctive challenges related to income generation, livelihood sustainability, and market access. investigating the socio-economic aspects of small-scale chicken farming can assist in identifying focused strategies to enhance the well-being of these farmers, such as offering financial assistance, enhancing market connections, and supporting training initiatives. besides, the research findings provoke considerations about the broader environment of the poultry industry, including its role in food security and rural development. understanding the distribution of farm sizes is critical for creating policies that global sustainability research global scientific research 14 encourage comprehensive growth, guaranteeing that both small and large-scale farmers contribute to overall industry resilience and sustainability. table 1: demographic attributes of chicken farmers

within the agricultural sector, especially for breeders who encounter various uncertainties and challenges in their operations. it is major that one-quarter of the breeders, as shown by the remaining 25% in figure 1, were uninformed about the availability of insurance. this observation emphasizes a possible gap in communication or outreach efforts pertaining to agricultural insurance. gaining insight into the reasons for this lack of awareness could be critical in formulating strategies to close the knowledge gap and ensure that a greater number of breeders can take advantage of risk mitigation measures. the study is consistent with the work of ojogbane and gbigbi (2022) which lends additional credibility and context to the current findings. according to ojogbane and gbigbi (2022), a considerable percentage of poultry farmers in kogi state were aware of the nigerian agricultural insurance scheme (nais). the alignment between the two studies implies that awareness levels have remained constant over time, and breeders in the region continue to be knowledgeable about the availability of agricultural insurance options. the importance of this awareness becomes even more apparent when evaluating the function of insurance in risk management within the agricultural sector. agriculture is intrinsically vulnerable to various risks, including weather-related events, diseases, and market fluctuations. insurance offers a financial safety net for breeders, providing protection against unexpected losses and enabling the continuity of agricultural activities. the implications of these findings transcend mere recognition of insurance availability. they open pathways for further research and interventions aimed at understanding the factors influencing awareness levels, addressing potential obstacles, and improving outreach programs. policymakers, agricultural extension services, and insurance providers can work together to create targeted initiatives that not only increase awareness but also educate breeders on the benefits and complexities of agricultural insurance. figure 1: level of awareness of insurance among poultry farmers 75% 25% fig. 1: respondents awareness of insurance yes no global sustainability research global scientific research 16 farmers attitude towards insurance the findings reveal that a major percentage of poultry ranchers, specifically 56%, display a lack of concern or indifferent attitude towards obtaining insurance, whereas only 44% exhibit a favorable attitude towards insurance coverage (fig.2). this indicates that a considerable number of poultry ranchers may not recognize the value or significance of securing insurance for their businesses. moreover, a study conducted by alabi et al (2023) also indicates that this pessimistic perspective regarding insurance uptake is not exclusive to poultry ranchers but could reflect a widespread sentiment among farmers, including those engaged in crop production. this similarity in attitudes across various agricultural sectors may suggest broader challenges or perceptions related to insurance within the agricultural community. it is essential to acknowledge that these findings could have major ramifications for the insurance sector and policymakers who seek to enhance insurance uptake among farmers and poultry ranchers. comprehending the reasons underlying this negative disposition and addressing them could be essential in promoting greater insurance enrolment within these industries. figure 2. attitude toward insurance determinants of utilization of insurance services the determinants of insurance service utilization among poultry farmers are presented in table 2. flock size the results, presented in table 2 indicate that flock size exhibits a positive correlation with insurance utilization, evidenced by a coefficient of 0.0037 and a z-value of 2.47, attaining statistical significance at the 5% level (p = 0.614). the marginal effect (dy/dx) of 0.0001, while minimal, suggests that as flock size increases, the likelihood of using insurance services also experiences a slight uptick. this observation is consistent with the perspective that farmers overseeing larger operations are more inclined to view insurance as beneficial due to their heightened exposure to risk, given that they have more to lose in terms of potential losses. this positive association between flock size and insurance adoption reinforces the notion that larger-scale farmers may exhibit a greater inclination 66, 44% 84, 56% fig. 2: respondents attitude toward insurance positive attitude negative attitude global sustainability research global scientific research 17 to safeguard their assets, as any loss could result in considerable financial difficulties. the finding corroborates the conclusions reached by olutumise et al (2023) regarding poultry farmers in ondo state. a major interpretation of this finding is grounded in the economic rationale for insurance utilization. typically, larger flock sizes indicate more substantial investments in poultry farming endeavors. as farmers allocate increased resources, both financial and human, to the growth of their flocks, the potential risks linked with poultry farming become increasingly evident. these risks may include epidemics, environmental calamities, or variations in market conditions that could result in important financial consequences. awareness of insurance awareness of insurance demonstrates a notable negative correlation with insurance utilization, exhibiting a coefficient of -2.9037, a z-value of -2.42, and a probability of 0.016, important at the 5% level. the marginal effect of -0.4614 indicates that insufficient awareness regarding insurance substantially diminishes the likelihood of insurance adoption. this result emphasizes the essential role that awareness plays in shaping insurance uptake. agricultural producers who lack sufficient information about insurance options, advantages, and processes are less likely to engage, probably due to uncertainty or misconceptions regarding the value of insurance. this finding indicates that focused awareness campaigns could be essential in enhancing insurance utilization rates among farmers. the result corroborates the study by ojogbane and gbigbi (2022), which argues for a positive correlation between awareness status and the likelihood of willingness to pay for insurance, further reinforcing the significance of awareness in decision-making. this alignment with technology adoption illustrates a broader trend wherein knowledgeable decision-making is connected to awareness, not only within the scope of insurance but across multiple sectors. furthermore, the negative correlation between awareness and insurance utilization emphasizes a potential obstacle that policymakers must address. this may reflect challenges such as inadequate access to information, ineffective communication channels, or even misunderstandings about the advantages of agricultural insurance. identifying these obstacles is essential for creating targeted interventions aimed at enhancing awareness and, as a result, increasing insurance utilization rates among farmers. attitude toward insurance the perspective on insurance is another important factor that affects insurance usage, with a positive coefficient of 3.6538, a z-value of 2.93, and a probability of 0.003, which is major at the 1% level. the marginal effect of 0.3172 indicates that a more positive view of insurance considerably enhances the likelihood of adoption. this finding suggests that individuals perception and belief in the effectiveness and reliability of insurance play a important role in motivating farmers to acquire insurance. a positive attitude may arise from perceived benefits or confidence in insurance providers, emphasizing the necessity of cultivating positive views through consistent service delivery and customer education. recognizing these psychological factors can assist policymakers, insurers, and agricultural extension services in designing interventions to positively impact farmers' views. farmers face numerous risks, which can include uncertainties related to weather and fluctuations in the market. an optimistic perspective regarding insurance may indicate that a farmer acknowledges the importance of managing risks and comprehends the role of insurance in mitigating the impact of unforeseen occurrences. ajemunigbohun et al (2020) study supports the current findings of this investigation. this finding reinforces the notion that promoting risk awareness and education regarding insurance benefits can be a strategic method for encouraging adoption among farmers. the positive relationship indicates that establishing trust in the insurance industry is essential for increasing adoption. farmers with positive attitudes may view insurance providers as dependable global sustainability research global scientific research 18 partners in protecting their agricultural investments. therefore, efforts to enhance transparency, simplify insurance processes, and provide clear information about the benefits can contribute to establishing trust and, in turn, nurturing positive attitudes. premium the cost of premiums has a notable adverse effect on the utilization of insurance, with a coefficient of -2.6684, a z-value of -2.27, and a probability of 0.023, which is major at the 5% level as depicted in table 2. the marginal effect of -0.4357 suggests that enhanced premiums dissuade farmers from acquiring insurance. this finding is consistent with economic theory, as high costs diminish the perceived affordability and cost-effectiveness of insurance for farmers. farmers, especially those with limited resources, may consider insurance premiums to be a financial strain, opting to manage risks independently. this result emphasizes the necessity of designing affordable insurance products that cater to the financial capabilities of smallholder farmers, since exorbitant premiums may prevent their participation. bear in mind that the negative correlation identified in this study emphasizes the critical significance of affordability in influencing farmers' insurance-related decisions. the discovery corroborates the idea that enhanced premium costs can are an obstacle, restricting the accessibility of insurance for farmers. this indicates that a considerable segment of the agricultural population may be left outside the protective scope of insurance due to financial limitations created by premium costs. as a result, this could leave farmers more exposed to heightened risks and vulnerabilities, especially when confronted with unpredictable events such as adverse weather, crop failures, or other insurable hazards. this finding concurs with gbigbi and ndubuokwu (2022). the differing result in relation to other research emphasizes the contextual aspects of insurance utilization behaviors. the importance of affordable premium structures, as demonstrated in the study by ojogbane and gbigbi (2022); hossain et al. (2022), cannot be underestimated. the fact that nearly all the farmers in that study expressed a willingness to pay any premium for insurance utilization emphasizes the critical impact of the affordability factor on farmers' perspectives regarding insurance. this finding carries major policy implications. it is essential for policymakers and insurance providers to carefully manage the equilibrium between ensuring the financial sustainability of insurance programs and guaranteeing that they are accessible and appealing to the target audience. this requires a reassessment of premium structures and the development of creative approaches to enhance affordability, possibly through subsidies, risk-pooling strategies, or alternative financial instruments that mitigate the fiscal strain on farmers. access to credit as shown in table 2, access to credit has a positive and major impact on insurance utilization, with a coefficient of 2.1299, a z-value of 2.01, and a probability of 0.044, which is major at the 5% level. the marginal effect of 0.2828 indicates that farmers with access to credit are more inclined to adopt insurance services. access to credit may enhance a farmer's ability to pay for insurance premiums, thereby promoting participation. besides, some credit providers may stipulate insurance coverage as a prerequisite for loan approval, directly linking credit access with insurance utilization. this finding indicates that improving farmers' access to credit could simultaneously bolster their capacity to afford and adopt insurance. this result emphasizes the essential role that credit accessibility plays in influencing farmers' choices to obtain insurance coverage and actively engage with insurance services. the finding corresponds smoothly with the insights presented by gbigbi and ndubuokwu (2022) study, emphasizing the facilitative role of financial resources in managing risks through insurance. this alignment further strengthens the reliability and consistency of the observed relationship, adding further credibility to the research global sustainability research global scientific research 19 findings. one major implication of this positive relationship is the potential for access to credit to are a catalyst for enhancing farmers' resilience to various risks. access to credit has improved for farmers, which enhances their capacity to manage the uncertainties fundamental in agricultural activities. this increased financial flexibility allows them to actively seek insurance coverage, thereby creating a stronger safety net against unforeseen occurrences such as crop failures, natural disasters, or fluctuations in the market. occupation the occupation variable, exhibiting a positive coefficient of 3.1793, a z-value of 2.46, and a probability of 0.014 (which is important at the 5% level), indicates a strong positive effect on insurance utilization. the marginal effect of 0.6186 implies that the character of a farmer's primary occupation plays an important role in their propensity to adopt insurance. farmers who are more commercially oriented or whose income predominantly hinges on farming may experience a heightened necessity to protect their livelihood through insurance. this positive correlation suggests that initiatives aimed at promoting insurance services could be particularly effective if they focus on fulltime farmers who are more financially reliant on agricultural productivity. the financial implications associated with poultry farming are considerable. full-time poultry farmers allocate substantial resources to acquire and maintain poultry infrastructure, procure high-quality breeds, and oversee daily operations. in contrast to part-time farmers, who may have diversified income streams, full-time poultry farmers substantially depend on the success of their poultry operations for sustenance. the fundamental financial risks related to poultry farming, stemming from variables such as disease outbreaks, market fluctuations, or adverse weather conditions, call for a comprehensive risk management approach. in this scenario, insurance becomes an essential instrument for alleviating financial losses due to unpredictable events. besides, the reliance on poultry farming as the sole or primary income source heightens sensitivity to economic changes. any disruption in poultry production or income can result in an immediate and direct effect on the financial stability of full-time poultry farmers. acknowledging this vulnerability, these farmers are more inclined to pursue insurance coverage as a strategy for establishing a safety net against unforeseen circumstances. the desire to safeguard one’s livelihood is a strong motivator for actively engaging with insurance services. the correlation implies that full-time poultry farmers may possess a more important understanding of the risks related to their profession. this increased awareness might arise from their daily involvement and practical experience in managing various facets of poultry farming. consequently, they are more likely to evaluate potential risks and take proactive steps to mitigate them, including seeking insurance services. table 2: factors influencing utilization of insurance services variables coefficient std error z probability dy/dx education -0.34502 0.9298 -0.37 0.711

** =significant at 5% global sustainability research global scientific research 20 level of use of insurance services the level of use of insurance services among poultry farmers was analyzed based on key indicators, as presented in table 3. extension services (es) with a score of 2.30, extension services are the most commonly used among poultry farmers as shown in table 3. this high degree of involvement indicates that farmers recognize the importance of these services in providing technical assistance, information on best practices, and guidance on farm management. extension services are likely critical in helping poultry farmers to improve their production processes and tackle challenges such as disease management, feed efficiency, and productivity enhancement. the frequent use of extension services may also reflect their accessibility and importance to farmers' daily activities. extension agents play an essential role in connecting the knowledge gap between research findings and field applications, which is particularly essential in rural areas with limited information access. increasing the range and frequency of extension services could further boost farmers' productivity and resilience against common risks. the utilization of extension services has been highlighted as critical to the functionality of agricultural sectors, particularly among poultry farmers. as shown in the work by shkembi et al. (2024) extension services are pivotal for enhancing sustainability and providing both practical and academic knowledge to farmers, thus bridging the gap between research and actual farming practices. additionally, mishra and singh (2024) note that tailored training and the efficient delivery of agriculture-related knowledge contribute significantly to farmers' adoption of modern techniques in livestock management. the consistent emphasis in these studies on enhancing accessibility and responsiveness of extension services suggests a strong correlation between their utilization and farmers' productivity levels. veterinary services (vs) with a score of 2.16, veterinary services are also commonly accessed, showing poultry farmers' recognition of the significance of animal health and disease management. the availability of veterinary services allows farmers to receive prompt medical care for their flocks, which is essential in preventing losses from illnesses, improving flock productivity, and maintaining overall poultry health. however, challenges such as the expense and accessibility of these services may persist in limiting their overall effectiveness. there is also a chance that some farmers rely on informal veterinary support due to insufficient formal veterinary coverage in rural areas. enhancing access to veterinary services and possibly reducing their costs could improve health outcomes for poultry flocks and promote sustainable farming practices. veterinary services are recognized for their importance in managing animal health among poultry farmers. as reported by tsay & paulson (2024), the provision of veterinary care directly impacts flock health and productivity. the report emphasizes the necessity of these services in preventing disease outbreaks, which, if ignored, could lead to substantial economic losses (shkembi et al., 2024). furthermore, mishra and singh (2024) state that while veterinary services are crucial, their accessibility remains a challenge, and improving these services could yield more robust livestock practices. training of farmers (tof) according to table 3, training of farmers received a score of 2.22, suggesting that poultry farmers actively engage in training programs. training sessions offer essential knowledge in areas such as farm management, disease global sustainability research global scientific research 21 prevention, and the adoption of innovative farming techniques, which can directly boost productivity. the high engagement rate indicates that farmers are aware of the advantages of training and may consider it a worthwhile investment to enhance their farm operations. nevertheless, the accessibility of training and the relevance of the curriculum could be improved to make sure that farmers are sufficiently equipped to handle emerging industry challenges. besides, consistent and updated training programs could address the changing environment of poultry farming and enhance farmers' ability to adapt to new risks and opportunities. training programs represent an essential area of focus for poultry farmers, as outlined in the studies by khanal et al. (2024) which illustrate that participation in training significantly enhances the farmers' knowledge and capability in adopting modern farming practices. furthermore, koprivica et al. (2024) discuss the role of training in overcoming barriers to the adoption of insurance and risk management strategies, highlighting that informed farmers are more likely to utilize available insurance products effectively. the ongoing need for updated and targeted training regimens is corroborated by oben et al. (2024) who stress that adapting curricula to meet current agricultural challenges can strengthen farmers' responses to risks. general risk coverage (grc) general risk coverage has a score of 2.02, reflecting moderate utilization by poultry farmers. this service likely offers a form of fundamental protection that addresses common risks in poultry farming, such as disease outbreaks and severe weather. farmers’ adoption of this coverage may arise from a need to safeguard their investments against unforeseen events. however, the moderate score suggests that some farmers may perceive insurance coverage as either insufficient or costly. expanding general risk coverage to encompass a broader range of risks and making it more affordable could encourage more farmers to take advantage of this service, thereby enhancing the poultry sector's resilience to unexpected events. general risk coverage shows moderate utilization among farmers, reflecting a necessary protective measure against common agricultural vulnerabilities. the analysis by philippi & schiller (2024) suggests that expanding risk coverage could better align with farmers' needs and lead to increased uptake. moreover, mishra & singh (2024) highlight that understanding the scope of risks covered by insurance programs can support farmers in securing their investments. provision of premium subsidy (pps) with a score of 1.80, the provision of premium subsidy is not widely used by poultry farmers as indicated in table 3. this finding indicates that premium subsidies, which could make insurance more accessible, are not reaching farmers effectively or that the available subsidy is insufficient to offset costs. cost is often a major barrier to insurance adoption among small-scale farmers, and this underutilization could indicate that the subsidies provided are inadequate to make a meaningful impact. addressing this issue may involve raising subsidy levels, simplifying the application process for subsidies, and guaranteeing that farmers are well-knowledgeable about the financial support available to them. the underutilization of premium subsidies is a noteworthy concern, as indicated in studies by cha et al. (2024) which emphasize that without adequate subsidies, farmers may remain hesitant to adopt insurance coverage. the findings by koprivica et al. (2024) affirm that significant premium subsidies are crucial for increasing the uptake of insurance products among rural populations, suggesting a direct correlation between subsidy levels and farmer participation rates. furthermore, ma et al. (2024) indicate that governments must ensure that subsidies are sufficient to lower entry barriers for farmers into the insurance market. global sustainability research global scientific research 22 insurance coverage of equipment (icoe) scoring 1.82, insurance coverage of equipment is another service that is not widely used. this low score suggests that poultry farmers may not perceive equipment insurance as essential, or they might view the premiums as too high compared to the perceived risk or replacement cost of their equipment. alternatively, some farmers may be unaware of this coverage option. given that equipment represents a substantial investment in poultry farming, promoting the advantages of insuring equipment could help protect farmers’ assets and maintain operational continuity in the event of equipment damage or failure. the low utilization rate for insurance coverage of equipment appears linked to perceptions of cost versus risk, as explored by tsay & paulson, (2024) who found that farmers prioritize covering more immediate risks over equipment. the research by cha et al. (2024) supports this by suggesting that raising awareness about the benefits and necessity of equipment insurance can change farmers' attitudes. coinsurance service (cis) coinsurance service achieved a score of 1.88, indicating minimal utilization among poultry farmers. coinsurance, which involves the sharing of risk between the insurer and the insured, can be a financially efficient method for farmers to mitigate their financial exposure. however, the low score suggests that poultry farmers may either not understand the concept of coinsurance or lack confidence in its benefits. educating farmers on how coinsurance works and its potential to reduce individual risk burdens could help increase uptake. besides, redesigning coinsurance policies to better align with farmers’ financial capacities and risk tolerances might improve its appeal. the minimal uptake of coinsurance services indicates a gap in understanding among farmers regarding how these services can mitigate financial exposure. research by khanal et al. (2024) emphasizes an educational approach to better inform farmers about coinsurance and its mechanics. additionally, ojogbane & gbigbi (2022). underline that clearer policy designs that consider farmers' financial capabilities could enhance the attractiveness of coinsurance. payment of indemnity (poi) payment of indemnity, which has a score of 1.82, indicates low utilization. this observation may suggest that poultry farmers are either unaware of their eligibility for indemnity payments or perceive the claims process as tedious and uninviting. indemnity payments are designed to provide compensation to farmers for losses and can play an essential role in assisting them to recover from adverse situations. by simplifying and simplifying the claims process while enhancing awareness regarding the operation of indemnity payments, it is possible to encourage a greater number of farmers to use this service as a safety net for losses. indemnity payments show low engagement levels, and this may be attributed to the complexity involved in the claims process as stated in studies by philippi and schiller (philippi & schiller, 2024). misunderstandings regarding eligibility and the claims process can deter farmers, as noted by mishra and singh, who argue for educational initiatives to simplify these operations (mishra & singh, 2024). furthermore, improved communication about the potential benefits of indemnity payments could encourage farmer participation. global sustainability research global scientific research 23 encouraging institutional lenders to lend more to agriculture (eil) with a score of 1.80, the initiative focused on encouraging institutional lenders to lend more to agriculture is currently underutilized. this may reflect various challenges such as limited access to financial institutions, high interest rates, or stringent lending terms that deter poultry farmers from seeking credit. enhancing poultry farmers' access to affordable credit and easing collateral requirements could assist greater borrowing, enabling farmers to invest in their operations and potentially enhance productivity. furthermore, encouraging stronger collaborations between insurance providers and financial institutions could render borrowing more attractive by combining loans with insurance coverage, thereby affording farmers additional protection against financial risks. the initiative to encourage institutional lenders reflects a broader economic support structure necessary for farmer growth. as evidenced by li et al. (2024) the facilitation of easier access to credit can significantly boost agricultural expansion. studies suggest that reducing barriers such as high interest rates can encourage more farmers to seek loans that could enhance productivity (peirong, 2024). limitations confronting utilization of insurance services this reveals that every participant (100%) did not have enough knowledge about the benefits of agricultural insurance as presented in table 4. this lack of understanding could prevent them from using insurance services. a complete consensus among participants (100%) regarding this matter indicates that the implementation of insurance policies in the agricultural sector is challenging and may be discouraging. for instance, muraya et al. (2024) indicate gaps in farmers' knowledge regarding weather index insurance (wii) but do not report a specific 100% unawareness, suggesting that awareness levels can vary and are contextual. all participants (100%) experienced delays in receiving indemnity payments, which can be frustrating and create financial strain. moreover, challenges related to indemnity payments, with significant delays reported by farmers, align with udoh et al.’s (2024) findings that mention a notable percentage of respondents encountering delays, which can dissuade farmers from pursuing insurance options due to frustrations. table 3: level of insurance services utilization services mean standard deviation utilization pps 1.80 0.70 low es 2.30 0.71 high vs 2.16 0.77 high icoe 1.82 0.77 low grc 2.02 0.77 high cis 1.88 0.77 low poi 1.82 0.75 low eil 1.80 0.76 low tof 2.22 0.79 high note: a mean score ≥ 2.00 indicates high utilization, while a mean score < 2.00 indicates low utilization. standard deviations indicate variations in responses among poultry farmers regarding the extent of insurance service utilization global sustainability research global scientific research 24 this aligns with the issues of cash flow and distrust toward the insurance system. another shared concern suggests that the compensation received through insurance policies is inadequate to cover the losses experienced by participants (100%), which undermines the purpose of insurance. the consensus regarding insufficient compensation from insurance policies is reflected in the findings of charamba (2024), who discusses the inadequacy of compensation schemes and their funding, highlighting farmers' dissatisfaction. this supports the claim regarding inadequacy of compensation but does not suggest that all participants indicated this uniformly. a considerable number of participants (68%) found that the procedures for securing insurance coverage were protracted, which may dissuade them from seeking insurance as seen in table 4. an important number (66%) of participants voiced worries that insurance claims might not be fulfilled when necessary. this skepticism regarding the insurance system can discourage farmers from using insurance services. participants' concerns regarding prolonged procedures (68%) and difficulties in accessing insurance representatives (56%) do align with broader trends. however, the reference by kanchai et al. (2024) does not pertain to the hurdles in accessing insurance representatives. more than half of the participants (54%) were not aware of the insurance options available, emphasizing needing enhanced communication and education about agricultural insurance. over half (56%) of the participants indicated difficulty in reaching insurance representatives. this can pose a logistical challenge for farmers who may need help or information about their policies. a notable proportion of participants (52%) encountered financial limitations due to their low income as poultry farmers, making it difficult to pay for insurance premiums. lastly, the financial constraints reported by participants resonate with observations by koprivica, et al (2024) who states that low financial capacity restricts rural populations' ability to afford insurance premiums. only 48% of participants viewed the payment of premiums as a barrier to their use of insurance services. this indicates that while some participants experience issues related to premium payments, it is not the most important concern among them. research hypothesis demographic characteristics of respondents and utilization of insurance services the results detailed in table 5 illustrate the connection between various socioeconomic characteristics and using insurance services among the respondents, as analyzed through the chi-square test. the chi-square value (x²value), degrees of freedom (df), and asymptotic significance (p-value) for each variable assist in evaluating whether there exists a statistically major correlation between the characteristics and using insurance services. sex: the result from the chi-square test regarding sex reveals an extremely low x²-value of 0.001 alongside a pvalue of 0.979. this enhanced p-value, greatly exceeding the standard cutoff of 0.05, indicates that there is no meaningful association between sex and the adoption of insurance services. this outcome suggests that both men and women in the study sample exhibit similar chances of using insurance services. as insurance uptake is frequently associated with financial or risk-related aspects rather than solely gender, this finding indicates that gender-neutral policies and outreach strategies may be suitable for encouraging insurance enrollment among both male and female participants. while the present study found no significant association between sex and insurance usage, other research indicates that gender can play a role in agricultural insurance uptake. for instance, a study on crop insurance among smallholder maize farmers noted that insurance appeared to be more biased against women among subscribers (bai et al. 2024). however, specific studies on poultry farmers found that sex was a significant factor influencing participation in agricultural insurance. global sustainability research global scientific research 25 table 4: limitations confronting utilizing insurance services

limitation as a challenge in utilizing insurance services. some limitations were reported by all respondents (100%), emphasizing their critical impact on insurance uptake. age: the chi-square value for age is recorded at 30.469, with 26 degrees of freedom, and an asymptotic significance level of 0.249. while the chi-square statistic is relatively substantial, the associated p-value of 0.249 surpasses the 0.05 significance threshold, signifying no statistically major link between age and insurance services. this indicates that age may not play a critical role in the decision to use insurance services among the study participants. although age generally influences financial choices, including the adoption of insurance, due to correlations with income stability and risk acceptance, this analysis shows that insurance usage remains consistent across various age groups, implying that insurance needs and behaviors are more evenly distributed across different age segments in this instance. the present study found no significant link between age and insurance services. however, other research suggests that age can influence insurance adoption. for example, a study on poultry farmers indicated that age was a significant factor affecting participation in agricultural insurance (udoh et al 2024) another study highlighted that age, along with education level and access to extension services, influenced the adoption of insurance as a climate risk management strategy (baba et al 2024). marital status: the chi-square result shows an x²-value of 2.942 and 3 degrees of freedom, with a p-value for marital status being 0.401. this value emphasizes the absence of a statistically major relationship between marital status and insurance service utilization. regardless of whether respondents are single, married, divorced, or widowed, their likelihood of engaging with insurance services remains largely unchanged. this finding implies that marital status may not greatly influence insurance usage, despite the possibility that married individuals sometimes feel a heightened necessity for financial protection. the lack of a major correlation might suggest that family-related considerations do not primarily drive insurance decisions within this sample, and therefore, promoting insurance as a measure of family security may not considerably alter utilization patterns. the present study found no significant relationship between marital status and insurance usage. however, a study on crop insurance among smallholder farmers found that marital status was correlated with the decision to use crop insurance (aina et al 2024). this suggests that marital status might influence insurance uptake in specific contexts. education: the chi-square value related to education stands at 1.996, accompanied by a p-value of 0.369, which indicates no major correlation between education level and insurance usage. it is commonly believed that educational attainment influences individuals' choices regarding the adoption of insurance services, with higher global sustainability research global scientific research 26 education levels potentially enhancing awareness of financial products and their advantages. nevertheless, the absence of a statistically major correlation in this instance indicates that educational background might not heavily affect whether respondents opt to use insurance services. this could point to the possibility that information and access to insurance are affordably available to individuals across different educational levels, or that mere knowledge is not enough to encourage insurance adoption without supporting factors like affordability or accessibility. while the present study found no major correlation between education level and insurance usage, other research indicates that education significantly influences agricultural insurance adoption. for example, studies have shown that farmers with higher educational levels are more likely to understand and participate in agricultural insurance (ugwuja et al 2024). educated farmers are better equipped to appreciate the benefits of crop insurance. farming experience: the chi-square analysis for farming experience yields x² = 10.896 with 13 degrees of freedom, and a p-value of 0.620, indicating no statistically major relationship between farming experience and using insurance services. this result suggests that respondents, regardless of their farming experience whether they are novices or seasoned farmers do not show major differences in their patterns of insurance usage. one might expect that more experienced farmers would seek out insurance for protection against risks they have faced over time, but this finding implies that, within this sample, experience does not lead to increased insurance uptake. this outcome may emphasize needing customized outreach that emphasizes the specific advantages of insurance for farmers across all experience levels. the present study found no significant relationship between farming experience and insurance usage. however, other studies suggest that farming experience can influence insurance adoption. for instance, a study in benin found that farming experience was a determinant of participation in agricultural insurance schemes (zoundji et al. 2024). table 5: chi-square test on socioeconomic characteristics and utilization of insurance services variables x2 – value df asymp. sig. (2 sided) sex 0.001 1 0.979 age 30.469 26 0.249 marital status 2.942 3 0.401 education 1.996 2 0.369 farming experience 10.896 13 0.620 household size 9.811 12 0.633 note: the results indicate that none of the socioeconomic characteristics tested (sex, age, marital status, education, farming experience, and household size) have a statistically significant relationship with the utilization of insurance services, as all p-values (asymp. sig.) are greater than 0.05. household size: concerning household size, the chi-square test results in an x² = 9.811, with 12 degrees of freedom and a p-value of 0.633, indicating no substantial association with insurance service utilization. household size typically influences financial decision-making, as larger families may seek additional protection for their dependents; however, the lack of a major correlation in this case suggests that respondents' decisions regarding insurance usage are not swayed by the number of individuals in their household. this might imply that insurance companies could focus on emphasizing individual-centered benefits in their outreach, since household size does not become a critical factor affecting the decision to use insurance services. the present study found no substantial global sustainability research global scientific research 27 association between household size and insurance service utilization. while household size typically influences financial decision-making, specific studies on agricultural insurance often emphasize other socioeconomic factors like income and employment status. however, household size positively influences insurance decisions through its impact on financial needs and risk management strategies (obalola et al 2024). influence of insurance services on income shocks the findings in table 6 demonstrate the effect of different insurance services on income shocks experienced by poultry farmers. regarding model performance, the r² value of 65.16% indicates that the model accounts for a notable portion of the variation in income shocks, with the independent variables explaining more than 65% of the differences. this indicates that the elements included in the model play a essential role in elucidating income shocks among poultry farmers. the f-ratio of 12.23 further reinforces the overall relevance of the model, showing that the combined effect of the independent variables on income shocks is statistically major and not a result of random fluctuations. the provision of subsidies (pps) demonstrates a major negative association with income shocks, exhibiting a coefficient of -17.913 and a t-ratio of -2.68, indicating that subsidies effectively help to lessen income shocks among poultry farmers. subsidies can provide financial assistance during crises, enabling farmers to manage unexpected losses or costs. they help minimize expenses for farmers, allowing them to allocate a greater proportion of their income toward savings or risk mitigation activities. when subsidies are in use, farmers may experience greater financial flexibility and a reduced need for credit during periods of income volatility. therefore, pps may bolster their resilience to income shocks by offering a financial cushion. this finding emphasizes the significance of government or organizational subsidies as essential mechanisms for alleviating the effects of economic uncertainty or unexpected events, particularly within the unstable agricultural sector. the statistically major negative impact indicates that poultry farmers receiving subsidies are better positioned to absorb income shocks, which may arise from factors such as market price changes, disease outbreaks, or natural disasters. a study on the impact of subsidy removal on smallholder livestock farmers in nigeria highlights that the removal of subsidies led to increased costs and reduced productivity among these farmers (mohammed 2024). this supports the notion that subsidies can mitigate income shocks by reducing operational costs. conversely, the extension services (es) variable, with a coefficient of 1.091 and a t-ratio of 0.14, indicates a positive relationship with income shocks, although this effect lacks statistical significance. extension services can greatly educate farmers about optimum practices, strategies for managing risk, and effective resource utilization. the knowledge obtained from these services can lower the chances of losses and enhance productivity, indirectly bolstering farmers’ capacity to endure income shocks. farmers who have access to and use these services may achieve more consistent production results and improved income stability. although extension services aim to equip farmers with critical insights on best practices, crop management, and disease prevention, the absence of statistical significance implies that these services, while beneficial in enhancing long-term farm productivity, do not exert a strong immediate effect on alleviating income shocks. it is plausible that the influence of extension services is more prospective, concentrating on boosting farm productivity and sustainability rather than offering immediate financial support during crises. veterinary services (vs), which show a coefficient of -10.456 and a t-ratio of -1.22, also indicate a negative correlation with income shocks, but this effect is not statistically major. access to veterinary services has the potential to substantially diminish the risk of poultry loss due to disease, one of the most major threats in poultry farming. regular veterinary attention encourages healthier stock, thereby reducing possible income loss. thus, a high reliance on veterinary services enhances a farmer’s ability to withstand livestock-related income shocks. nevertheless, the lack of statistical significance for this variable emphasizes that, while veterinary services may global sustainability research global scientific research 28 contribute to farm steadiness by promoting healthy livestock, they do not exert a decisive enough impact on alleviating financial shocks in the short term. this may result from variability in the quality and accessibility of veterinary services or the fact that the financial implications of veterinary care may not be major enough to offset more considerable income shocks caused by external factors like market instability or climate-related issues. insurance coverage for equipment (icoe) shows a major negative connection with income shocks, registering a coefficient of -17.183 and a t-ratio of -2.38. this finding emphasizes that insurance coverage for essential farming equipment, such as incubators, feed systems, and heating units, is essential for reducing income shocks. breakdown of equipment can greatly disrupt poultry production; however, insurance coverage provides a safety net by reimbursing farmers for repair or replacement expenses. this enables poultry farmer to maintain operations without facing financial devastation. the statistical significance of this variable emphasizes the critical importance of insuring farming equipment, as it helps to mitigate the financial exposure of farmers to unforeseen equipment failures, thus enhancing their resilience against income shocks. the general risk coverage (grc) variable, with a coefficient of -2.583 and a t-ratio of -0.41, demonstrates a negative relationship with income shocks, yet the effect is not statistically major. general risk coverage is designed to protect farmers from a variety of risks, including extreme weather, fluctuating market prices, and other unpredictable factors. when farmers possess comprehensive coverage, they are more insulated from risks that could potentially disrupt income, contributing to a stronger buffer against income shocks. thus, the utilization of grc plays a role in ensuring steady income, even amidst unpredictable farming challenges. however, the low statistical significance indicates that this form of broad risk coverage may not be effective enough to greatly lessen income shocks among poultry farmers. this may result from general risk coverage being too generalized or not specifically customized to address the key risks encountered by poultry farmers, such as disease outbreaks or sudden market fluctuations. consequently, although general risk coverage may provide some protection, its effectiveness in mitigating income shocks seems limited. likewise, the coinsurance service (cis) variable, with a coefficient of 0.882 and a t-ratio of 0.13, indicates a positive relationship with income shocks, though the effect is again not statistically major. coinsurance involves sharing the cost of insurance between the farmer and the insurer, making insurance more affordable while still offering substantial coverage for risks. farmers using coinsurance services may be more capable of managing costs and accessing insurance, thereby increasing their protection against shocks without incurring the full cost of premiums. the shared financial burden aids in maintaining resilience without stretching resources too thin, but the low t-ratio suggests that the influence of coinsurance on income shocks is negligible. this outcome may imply that while coinsurance can lessen the financial burden on farmers to some degree, it fails to deliver adequate coverage to effectively mitigate the larger income shocks that poultry farmers frequently face. the slight positive coefficient indicates a minimal potential for coinsurance to aid income stability, but its limited effectiveness suggests that alternative financial protection strategies, such as indemnity payments or subsidies, are likely more impactful. payment of indemnity (poi), with a coefficient of -20.289 and a t-ratio of -2.81, emerges as one of the most major predictors of reduced income shocks among poultry farmers. indemnity payments, which reimburse farmers for losses incurred due to covered risks such as natural disasters or disease outbreaks, are essential in assisting farmers with recovering from income shocks. a high utilization of indemnity services directly contributes to the absorption of income shocks by providing funds exactly when income is at risk. the negative coefficient and high t-ratio signify that indemnity payments are very effective in diminishing income shocks. by compensating for lost income and covering unexpected costs, indemnity payments equip poultry farmers with the financial stability necessary to maintain operations during challenging times. this finding emphasizes the necessity of establishing effective indemnity mechanisms as a important approach for enhancing farmers' resilience to income shocks while promoting long-term agricultural sustainability. studies indicate that despite the benefits, many small-scale farmers global sustainability research global scientific research 29 have low demand for agricultural insurance products due to barriers such as high premiums and lack of awareness. this suggests that while indemnity payments can mitigate income shocks, their effectiveness might be limited if farmers do not utilize insurance products (attipoe, & adams 2024). encouraging institutional lenders (eil), with a coefficient of -13.428 and a t-ratio of -2.36, also exhibits a substantial negative relationship with income shocks as seen in table 6. access to formal credit from financial institutions provides poultry farmers the opportunity to secure loans that they can use for investments, recovery, or smoothing income fluctuations. institutional loans grant farmers essential liquidity during financial distress, enabling them to address cash flow issues, purchase inputs, or recover from unforeseen losses. the statistical relevance of this variable emphasizes needing assisting access to credit for farmers, especially in moments of financial instability. promoting institutional lenders to offer affordable and accessible credit options is an essential policy intervention for alleviating income shocks and enhancing financial resilience within the agricultural sector. a study on poultry farmers in nigeria found that only about 17% of respondents had accessed credit from formal lending institutions, highlighting significant barriers to accessing institutional credit. this suggests that despite the potential benefits, encouraging institutional lenders might not always lead to increased access for all farmers (lawi, et al. 2024) table 6:

at a 5% level of significance the training of farmers (tof), with a coefficient of -18.343 and a t-ratio of -2.98, displays a highly major negative effect on income shocks. training programs provide farmers with the knowledge and skills to more effectively manage their operations, enhance productivity, and adapt to changing conditions. by improving farm management practices, disease prevention, and risk management strategies, training can greatly minimize income volatility. the substantial statistical significance of this variable indicates that educational and capacity-building initiatives are notably effective in assisting farmers in dealing with income shocks. training enhances farmers' ability to make well-knowledgeable decisions, improve operational efficiency, and navigate financial challenges, thus decreasing their exposure to income fluctuations. this outcome emphasizes the value of farmer education and training as a crucial strategy for promoting resilience and ensuring sustainable agricultural practices. despite the benefits of training, some studies indicate that small-scale farmers often face barriers in adopting new technologies and global sustainability research global scientific research 30 practices. this suggests that while training can be effective, its impact might be limited if farmers do not fully integrate the knowledge into their operations (sanusi & dries 2024). conclusion this research emphasizes the significance of insurance services in the poultry farming industry and proposes methods to improve their use and effectiveness in safeguarding farmers against income fluctuations. it concludes that financial assistance is accessible to help farmers reduce their insurance premium expenses. however, many farmers seem to be missing out on this financial aid, which may be attributed to a lack of knowledge or comprehension regarding the subsidy program. farmers should obtain insurance coverage for their equipment, considering the high costs associated with agricultural machinery. if they are not making use of this service, it may signal the need for enhanced communication and outreach from insurance companies. coinsurance represents a collaborative financial agreement between the insurer and the insured. if farmers are not taking advantage of coinsurance options, it could stem from a lack of full understanding about how it operates or the benefits it can provide. the receipt of indemnity payments typically refers to the compensation that farmers receive when they experience a covered loss. if farmers are not getting their indemnity payments as anticipated, it could result from administrative problems or delays. optimizing the process is critical to ensuring that farmers receive their compensation without unnecessary delays. encouraging institutional lenders to offer more loans to the agricultural sector is also essential for farmers to invest in their businesses and obtain the necessary resources. to enhance the adoption and impact of agricultural insurance, programs such as providing premium subsidies, broadening insurance coverage to encompass equipment, and motivating institutional lenders should be implemented. training and outreach initiatives can help farmers grasp the advantages of coinsurance and how it can mitigate their financial risks. cultivating relationships between farmers and lenders is essential, along with offering incentives or guarantees to attract financial institutions to agricultural lending. establishing effective partnerships between poultry farmers and insurance agencies, including ongoing communication, workshops, and collaborations between farmers' groups and insurance companies, can help tailor insurance products to meet farmers' specific needs. successful mobilization efforts should include awareness campaigns, training sessions, and outreach programs to educate farmers about the advantages of insurance coverage, the available subsidies, and how to access these services. addressing issues such as enhancing knowledge sharing, optimizing processes, ensuring timely compensation, and tackling affordability concerns can significantly boost the impact and uptake of agricultural insurance. simplifying and expediting the procedures for obtaining insurance coverage will help reduce the obstacles faced by farmers. additionally, ensuring the prompt payment of indemnity and that compensation sufficiently addresses losses will help build farmers' confidence in insurance services. declaration acknowledgment: the authors sincerely appreciate

disaster management; abuja; e-governance; nigeria introduction in recent decades, the frequency and severity of disasters, both natural and man-made, have significantly increased, posing threats to lives, infrastructure, and economies across the globe. these events, which include earthquakes, floods, fires, and explosions, transcend national boundaries and affect both developed and developing nations alike. disasters such as the earthquakes in the middle east, floods in europe, and recurrent environmental crises in countries like nigeria, cameroon, and chad underscore the urgent need for proactive and technology-driven disaster management strategies (enenkel, guha-sapir & zaitchik, 2024; reuters reports, 2024). studies specific to nigeria show that flood-prone urban centres suffer severe impacts due to inadequate infrastructure, poor planning, and insufficient integration of ict-based mitigation tools. this is exemplified in the work of onugba, onugba, and bamigboye (2022), who reviewed resilient infrastructure options for flood risk management in nigeria. the world health organization (2007) defines a disaster as an event that disrupts the normal living conditions of a population and exceeds the capacity of the affected community to cope. while the unpredictable nature of disasters renders their complete prevention difficult, the strategic application of global sustainability research global scientific research 2 information and communication technology (ict) offers promising tools for reducing their impact. ict facilitates key functions such as mitigation, early warning, preparedness, response, and recovery. across the world, governments are increasingly turning to e-governance technologies—including geographic information systems (gis), thermal imaging, mobile apps, and satellite communications—to improve the effectiveness of their disaster management operations (djoumessi & mbongo, 2022). for example, evidence from ict-based disaster education in indonesia illustrates how mobile and web-based technologies significantly enhance community preparedness and responsiveness (uchida et al., 2021). e-governance, in the context of disaster management, refers to the use of digital tools to enhance the delivery of public services and foster efficient coordination between government agencies and the public (abasilim, gberevbie & ifaloye, 2017). when properly integrated, e-governance systems enable real-time access to data, facilitate early warning communication, and allow for coordinated and transparent stakeholder engagement. these tools are particularly relevant in rapidly urbanizing regions like abuja, nigeria’s federal capital territory (fct), which has witnessed a variety of disaster incidents in recent years, including floods, building collapses, and market fires. according to aghav, solanki, and palwe (2022), gis-based e-governance systems can support location-specific emergency services and coordination in dense urban areas, making them highly suitable for abuja's context. the federal capital territory emergency management agency (fema), established in 2013 under the national emergency management agency (nema) act of 1999, is the agency responsible for coordinating disaster risk reduction and emergency management in abuja. fema’s mandate spans the four critical phases of disaster management: mitigation, preparedness, response, and recovery (fema handbook, 2022). in fulfilling this mandate, fema has implemented several e-governance initiatives, such as gis mapping, dedicated emergency websites, satellite monitoring, and social media alert systems. these initiatives are designed to modernize disaster management and reduce the vulnerability of residents to both environmental and humaninduced hazards. however, as noted by rane et al. (2024), the success of such systems often hinges on adequate local capacity, sustained ict funding, and institutional alignment, factors that are frequently lacking in developing regions. despite these efforts, the federal capital territory continues to experience significant and recurrent disasters, raising questions about the effectiveness of fema’s e-governance strategies. notable incidents—such as the 2014 nyanya bombing, frequent floods in lokogoma and trade-more estate, and repeated fire outbreaks in areas like kubwa—have exposed several systemic weaknesses. public complaints about delayed emergency responses, inaccessibility of hotlines, limited early warning systems, and inadequate recovery support suggest that digital tools are not yet optimally deployed or utilized. a comparative review by syukron et al. (2024) emphasizes that disaster response systems combining mobile apps, geospatial mapping, and real-time alerts perform significantly better in urban crisis environments. given this context, this study critically examines the role and performance of e-governance initiatives within fema’s disaster management framework in the fct. specifically, it explores whether these digital tools have improved fema’s capacity to mitigate disaster risks during the pre-disaster phase. it also investigates the extent to which e-governance has enhanced preparedness efforts, enabling fema to anticipate and reduce the impact of potential hazards. furthermore, the study assesses whether these initiatives support timely and effective response operations in the post-disaster phase, as well as their ability to facilitate recovery and rehabilitation processes following disasters. by exploring these dimensions, the study contributes to a deeper understanding of how ict-driven governance mechanisms influence disaster risk management in urban nigeria. it aims to provide practical insights that can inform policy and improve the resilience of public emergency systems, especially in rapidly growing cities like abuja. global sustainability research global scientific research 3 literature review e-governance and its relevance to disaster management globalization, technological advancements, demographic shifts, and evolving political demands are transforming the functions of governments and public sector organizations. in response, governments are adopting more innovative, efficient, and citizen-centered approaches. one such strategy is e-governance, which offers a viable solution for improving public administration, enhancing service delivery, and promoting inclusive governance. e-governance refers to the use of information and communication technologies (icts) to support and improve governmental processes and citizen engagement. the oecd (2003) defines it as the application of icts to ensure transparency, accessibility, and responsiveness in government operations. similarly, the world bank (2012) emphasizes its role in transforming relationships between governments, citizens, businesses, and other institutions. scholars like oseni & dimgley (2014) and palvia & sharma (2007) highlight their administrative value and potential to enhance interactions between public servants and society, while bannister & walsh (2002) extend the concept to include civic participation and democratic governance. extending this scholarship, chima & victor (2023) demonstrate how demand-side factors—such as digital literacy and broadband costs, directly condition effective e-governance uptake in nigerian localities, showcasing the real-world constraints underlying theoretical frameworks. in practical terms, e-governance encompasses a range of digital functions, including e-registration, e-taxation, e-service delivery, e-education, e-participation, and e-policing (danfulani, 2013). these digital interventions are central to promoting the principles of good governance, such as transparency, accountability, equity, and citizen engagement (adeyemo, 2013). a particularly transformative domain of e-governance is disaster management, where ict systems—such as geographic information systems (gis), mobile messaging platforms, and webbased portals—enhance governments’ ability to issue timely warnings, identify high-risk zones, and coordinate emergency responses. as cleverley (2001) and backus (2001) observe, such tools facilitate real-time communication between authorities and the public, thereby increasing institutional responsiveness and public trust during crises. nonetheless, the application of these technologies in developing contexts like nigeria remains uneven. the effectiveness of e-governance in disaster management hinges on institutional readiness and infrastructural resilience. for instance, chima and ojochegbe (2022) report that systemic obstacles—including limited ict skills among public officials, inadequate funding, and low public digital awareness—can significantly undermine the success of e-governance initiatives aimed at emergency coordination and public safety. these findings are reinforced by chima and victor (2023), who emphasize the persistence of digital divides, such as high broadband costs and limited connectivity, which constrain citizen participation in digital public services like disaster alerts and emergency reporting systems (doi: 10.56556/jtie.v2i4.656). collectively, these challenges reflect broader structural issues prevalent across sub-saharan africa, where infrastructural deficits and technological inequalities compromise governance performance, especially under crisis conditions. however, the trajectory is not entirely discouraging. evidence from chima and oluwaseun (2020) presents a more optimistic outlook, illustrating how the successful deployment of ict tools in nigeria’s integrated payroll and personnel information system (ippis) has strengthened accountability and reduced corruption within the public sector. this case underscores the broader potential of transparent, ict-enabled systems—not only in financial management but also in enhancing the credibility, efficiency, and traceability of disaster-related logistics and emergency interventions. e-governance is often conceptualized within the government-to-citizen (g2c) model, which allows citizens to access public services and information conveniently and equitably (miller & walling, 2013). this model also global sustainability research global scientific research 4 supports participatory governance by enabling citizens to monitor projects, evaluate service delivery, and hold institutions accountable (palvia & sharma, 2007). in nigeria, e-governance has gained strategic attention. the national information technology development agency (nitda) was established to drive ict development and digital governance (adeyemo, 2013). initiatives include online portals, mobile apps, and digital platforms supporting poverty reduction, gender equality, environmental protection, and disaster response (olufemi, 2012; adeyemo, 2013). however, implementation remains constrained by several challenges: limited digital literacy, high internet costs, slow connectivity, and weak inter-agency integration (olufemi, 2012). corroborating these challenges, paul chima’s study on e-governance adoption at the university of abuja identifies inadequate funding, low awareness, resistance to change, and staff training gaps as significant inhibitors (chima & ojochegbe, 2022), highlighting systemic constraints shared across public institutions. addressing these issues is essential to realizing the full potential of e-governance in nigeria and other developing countries. especially in disaster management contexts, a robust g2c platform must overcome infrastructural, institutional, and capacity barriers to deliver real-time risk communication, facilitate coordination, and support recovery. integrating academic insights from paul chima and other peers anchors our understanding in nigeria’s policy reality and emphasizes the importance of context-sensitive approaches going forward. disaster management the concept of disaster has been widely explored in both academic and policy literature. its origin can be traced to the french word “desastre,” which translates to “bad star,” connoting misfortune or ill fate. a disaster is defined as a serious disruption of societal functioning that surpasses the coping capacity of the affected community (united nations, 2014). at the heart of disaster discourse lies an interconnected triad: hazards, vulnerability, and capacity. hazards may be natural, such as floods, earthquakes, or pandemics, or man-made, including technological accidents or environmental degradation. vulnerability relates to how exposed a population is to such hazards, shaped by factors like urban density, poverty, infrastructure quality, and access to basic services. capacity encompasses the physical, social, and economic resources communities have to anticipate, cope with, and recover from disasters. a recent systematic review by banda, mwale, and tembo (2024) highlights the importance of coupling community-based vulnerability reduction with technology-enhanced capacity building, particularly in southern africa. disaster management is a multi-stage process that includes mitigation, preparedness, response, and recovery (lindsay, 2012). mitigation involves long-term strategies—such as urban planning, building codes, flood mapping, and zoning laws—to reduce disaster impact. khaspuria, das, and pandey (2024) argue that this phase is most effective when supported by integrated data systems and earlywarning models that proactively build urban resilience. preparedness focuses on readying individuals, institutions, and systems to manage emergencies through planning, training, resource stockpiling, and public education (ifrc, 2000). according to fema’s 2022–2026 strategic plan, equitable preparedness is critical, as the agency states that “underserved communities often suffer disproportionately from disasters,” and that building a more resilient nation requires “proactively prioritizing actions that advance equity for communities and identifying groups that have historically been underserved” (fema, 2021). response encompasses immediate actions taken to protect lives and property during and after a disaster (gupta et al., 2011). although global attention increasingly emphasizes prevention, a swift and organised response remains crucial for reducing losses and suffering. recovery involves restoring services, infrastructure, and social systems. in it contexts, it includes backups, disaster recovery-as-a-service (draas), snapshots, and virtual recovery platforms (google cloud, 2024). raj, sharma, and taneja (2025) note that emerging ai and bigdata tools, such as predictive flood maps and resource optimization algorithms, are transforming recovery global sustainability research global scientific research 5 planning and logistics. the integration of ict and e-governance has significantly enhanced disaster management. technologies like drones, gis, satellite communication, thermal imaging, and mobile alerts are now vital for early warning, damage assessment, and inter-agency coordination (itu, cited in ostinsvig, 2006). raj et al. (2025) further confirm that ai/ml and simulation platforms are becoming core tools across all disaster phases. conclusively, disaster management is an inherently complex, multi-phase process that depends on coordinated planning, technological innovation, real-time communication, and human capacity. the effective synergy of mitigation, preparedness, response, and recovery, with inclusive governance and sustained investment, remains essential to managing both natural and human-induced disasters effectively. theoretical framework this study is anchored on the diffusion of innovation (doi) theory, originally developed by sociologist everett rogers in 1962. the theory provides a foundational lens for understanding how new ideas, technologies, or practices spread within a society or organization. it explains not only how and why innovations are adopted, but also the rate at which they disseminate across different social systems over time. a central feature of the theory is the emphasis placed on the role of communication in the adoption process, as outlined by rogers in his updated work in 2003. according to rogers, the diffusion of any innovation typically follows a five-stage process: awareness, interest, evaluation, trial, and finally, adoption or rejection. within this process, three critical elements interact to influence the outcome. the first is the innovation itself defined as any idea, practice, or object perceived as new by a person or group. the second is the communication channel, which refers to the means, whether formal or informal through which information about innovation is shared. the third is the social system, comprising the network of individuals, organizations, or communities through which the innovation is introduced and spread. the theory also identifies five specific attributes of an innovation that affect how quickly and widely it is adopted. these are relative advantage (the extent to which the innovation is perceived as better than what it replaces), compatibility (how well the innovation fits with the existing values, needs, and experiences of the target group), complexity (how difficult it is to understand or use), trialability (the ability to test the innovation on a small scale before full adoption), and observability (the degree to which the results of the innovation are visible and measurable to others). these attributes collectively shape the perceptions and behaviors of potential adopters within any given social system. application of the theory to this study the doi theory is particularly relevant to this study, which explores the adoption of e-governance innovations in disaster management in abuja, nigeria. in this context, tools such as online platforms, mobile applications, geographic information systems (gis), and digital communication channels are considered new and transformative innovations within the disaster management cycle, which includes mitigation, preparedness, response, and recovery. e-governance offers a clear relative advantage by enhancing the efficiency, transparency, and coordination of disaster management efforts among stakeholders such as government agencies, emergency responders, and local communities. for instance, gis technology allows authorities to identify and map high risk zones prone to flooding or structural collapse. mobile applications enable real-time alerts and support communitybased reporting of hazards. similarly, online portals streamline the distribution of aid and improve coordination during emergencies. these innovations directly address the shortcomings of abuja’s traditional disaster response systems, which have often been overwhelmed by challenges such as urban flooding and inadequate infrastructure (basahuwa, 2017). global sustainability research global scientific research 6 the communication strategies employed to disseminate these innovations are crucial to their success. government-led campaigns using television, radio, social media, and grassroots community workshops serve to educate stakeholders and build trust in new technologies. these platforms not only raise awareness but also foster interest and engagement, which are key steps in the innovation adoption process (heeks, 2006). patterns of adoption in abuja mirror the adopter categories described by rogers. innovators and early adopters, such as the federal capital territory emergency management agency (fema) often lead the way by experimenting with and championing new technologies. they are followed by the early majority, which includes local government units and non-governmental organizations (ngos) that become involved after the benefits of innovation are demonstrated. however, the late majority and laggards, who may be less digitally literate or more skeptical of government-led technologies, tend to adopt only after prolonged engagement and proof of effectiveness. in applying the five innovation attributes to the context of abuja, it becomes evident that each one plays a role in shaping outcomes. compatibility is vital; the new systems must align with existing local infrastructure and practices to be accepted. innovations perceived as overly complex or technical can hinder adoption, especially in low-literacy environments, making it essential to design user-friendly platforms that offer local language support. trialability is also important; pilot testing in disaster-prone communities allows for the demonstration of real-world benefits before full-scale implementation. finally, observability reinforces the adoption process, as visible improvements in response times and resource use increase confidence and encourage broader acceptance (alawadhi & morris, 2009; rogers, 2003). the role of the social system in this process cannot be overstated. the collective participation of government agencies, civil society organizations, community leaders, and the private sector creates the enabling environment for successful diffusion. through visible government leadership, consistent stakeholder engagement, and collaborative efforts, trust and legitimacy are built, which are essential for the long-term sustainability of e-governance tools in disaster management (heeks, 2006). the diffusion of innovation theory offers a robust framework for analyzing how and why e-governance tools are adopted within abuja’s disaster management landscape. it not only explains variations in the pace of adoption but also highlights the importance of aligning technological innovations with local realities and effective communication strategies. methodology of the study this study adopted a combination of survey research design and documentary sources to gather data. the survey research design, as described by obasi (1999), involves collecting data from a defined population through questionnaires or interviews and analyzing the results statistically to conclude. this approach was considered suitable due to its empirical nature, allowing the researcher to examine the relationships between variables under investigation. by using this method, the study effectively explored people's experiences, attitudes, beliefs, and behaviors regarding the use of e-governance in disaster management in abuja. the research was conducted within the federal capital territory (fct), which lies between latitudes 8°25' and 9°20' north and longitudes 6°45' and 7°39' east, covering approximately 8,000 square kilometers. established by decree no. 6 in 1976, the fct was carved out from niger, plateau, and kogi states. initially divided into nine development areas, it was later reorganized into six area councils: abaji, gwagwalada, kuje, kwali, bwari, and abuja municipal. the fct experiences three major weather conditions: a humid rainy season, an extremely hot dry season, and a short harmattan period. vegetation includes various savannah types and patches of rainforest, especially in the gwagwalada plains. the study population consisted of 528 individuals, including all 175 staff of the fct emergency management agency (fema) across departments such as administration, forecasting, response and mitigation (frm), relief and rehabilitation, monitoring and special duties, information and technology, and account and audit. global sustainability research global scientific research 7 the second category comprised 353 households affected by disasters across the six area councils of the fct. to select a representative sample, both probability and non-probability sampling techniques were employed. stratified random sampling helped divide the population into strata, while purposive sampling was used to select individuals with the most relevant experiences to answer the research questions. using taro yamane’s (1964) formula at a 5% margin of error, a sample size of 310 was determined, comprising 122 fema staff and 188 disaster-affected community members. proportional allocation based on strata size was used to determine the number of respondents from each department and community. data collection relied on a structured questionnaire and relevant publications. the questionnaire, based on a fivepoint likert scale (strongly agree to strongly disagree), was designed to gather both demographic information and insights into the application of e-governance in disaster management. a total of 310 questionnaires were administered to respondents. to ensure validity and reliability, the instrument underwent expert review for content validation, aligning the items with the research objectives. reliability was tested using cronbach’s alpha, yielding a coefficient of 0.84, indicating high internal consistency. the findings were further supported by existing literature. both primary and secondary sources of data were used. primary data came from the questionnaire, while secondary data were sourced from books, journals, newspapers, official fema reports, and relevant publications on ict and disaster management. this dual approach ensured comprehensive data collection. for data analysis, both descriptive and inferential methods were used. responses were tabulated and simple averages computed. additionally, tables and diagrams were used for clarity. an independent two sample t-test was employed to test the hypotheses and identify any significant differences in responses across the sample groups. data analysis test of hypotheses in this section, four statistical hypotheses were tested using the independent samples t-test. this statistical technique was employed to determine whether there were significant differences in the mean responses between two independent groups, fema staff and members of disaster-affected communities in the fct regarding the use of e-governance tools in disaster management. specifically, the analysis examined variations in perceptions across the four key components of the disaster management cycle: mitigation, preparedness, response, and recovery. data analysis was conducted using ibm spss statistics (version 25), ensuring accuracy and robustness in hypothesis testing. hypothesis one h0 there is no significant difference in the mean rating of fct emergency management agency (fema) staff and the affected communities’ opinions

statistically significant difference in the mean responses of fema staff and members of affected communities regarding the effectiveness of fema’s e-governance tools in enhancing disaster mitigation efforts within the federal capital territory (fct). the results revealed a statistically significant difference in the opinions of the two groups. the mean rating of fema staff (m = 3.38, sd = 0.39) was notably higher than that of the affected community members (m = 2.97, sd = 1.09), resulting in a mean difference of 0.41. this suggests that fema staff generally agreed that e-governance tools have improved disaster mitigation efforts, whereas affected community members expressed less agreement. the t-test yielded a calculated t-value (t₃₁₀) = 3.681, which exceeds the critical t-value of 1.96 at the 0.05 level of significance. additionally, the p-value = 0.000, which is less than the significance threshold of 0.05, further confirms the statistical significance of the result. given these findings, the null hypothesis (h₀), which stated that there is no significant difference in the mean responses of fema staff and affected communities is rejected. consequently, the alternative hypothesis (h₁) is accepted. this result implies that there is a significant divergence in perception between fema staff and disaster affected community members regarding the role of e-governance initiatives in disaster mitigation within the fct. while fema personnel view these digital tools as effective in reducing disaster risks, the community members appear less convinced of their impact or effectiveness. hypothesis two h0 there is no significant difference in the mean rating of fct emergency management agency (fema) staff and the affected communities’ opinions regarding the application

community members expressed considerable skepticism. the test produced a calculated t-value (t₃₁₀) = 9.84, which is well above the critical t-value of 1.96 at the 0.05 level of significance. additionally, the p-value = 0.000, which is significantly less than 0.05, confirms the result's statistical significance. based on these findings, the null hypothesis (h₀) which posited no significant difference between the two groups' responses is rejected, while the alternative hypothesis (h₁) is accepted. this result indicates a significant divergence in opinion between fema staff and disaster-affected communities regarding the effectiveness of e-governance tools in promoting disaster preparedness. while fema staff affirm the positive impact of such digital governance mechanisms, affected community members appear to hold contrasting views, potentially highlighting a gap in awareness, trust, or inclusiveness in preparedness strategies. hypothesis three h0: there is no

= 3.67, sd = 0.69) compared to the affected community members (m = 2.36, sd = 0.88), yielding a mean difference of 1.31. this indicates that fema personnel believe that e-governance initiatives facilitate timely and effective disaster response, while the affected communities do not share this perception. the calculated t-value (t₃₁₀) = 14.86 exceeded the critical t-value of 1.96 at the 0.05 level of significance, and the associated p-value = 0.000 was well below 0.05. these results confirm that the observed difference is statistically significant. as such, the null hypothesis (h₀) which stated that there is no significant difference between the perceptions of fema staff and affected community members is rejected. the alternative hypothesis (h₁) is therefore accepted. this finding implies a considerable perceptual gap between the implementing agency (fema) and the disaster-affected population regarding the responsiveness of fema’s e-governance mechanisms. while fema staff affirm that digital tools have improved the agency’s capacity to respond promptly to disasters, the affected communities appear to perceive a lack of adequate or timely intervention. global

author computation from spss (version 25) interpretation of results an independent samples t-test was conducted to examine whether there is a significant difference between the mean responses of fema staff and affected community members regarding the influence of e-governance on disaster recovery activities in the federal capital territory (fct). the results indicated a statistically significant difference between the two groups. fema staff reported a higher mean response (m = 2.83, sd = 1.17) compared to the affected community (m = 1.70, sd = 0.98), with a mean difference of 1.04. notably, both groups expressed disagreement with the notion that fema’s e-governance tools effectively facilitate disaster recovery activities in the fct, although fema staff's responses were relatively more positive. this difference in perceptions was statistically significant, as the calculated t-value (t₃₁₀ = 9.64) exceeded the critical value of 1.96 at the 0.05 significance level, and the p-value (p = 0.000) was less than 0.05. consequently, the null hypothesis (h₀), which posited no significant difference between fema staff and affected communities’ views on e-governance and recovery activities, was rejected, and the alternative hypothesis (h₁) accepted. this outcome suggests that while both fema staff and affected community members perceive limitations in the effectiveness of e-governance for disaster recovery, there remains a significant divergence in the extent of their views. the findings underscore the need for further investigation and potential enhancement of e-governance strategies to improve recovery efforts and align perceptions between the agency and the community. discussion of findings this section critically analyses the findings derived from the research questions, organized around four key dimensions of disaster management: mitigation, preparedness, response, and recovery, with a focus on the role of e-governance initiatives by fema in the federal capital territory (fct). the discussion synthesizes the perspectives of both fema staff and the affected community, revealing critical disparities and areas for enhancement in the deployment and effectiveness of digital governance tools in disaster management. e-governance initiatives and mitigation activities (pre-activity phase): the comparative analysis using an independent two-sample t-test reveals a statistically significant difference in perception between fema staff (mean = 3.38) and affected community members (mean = 2.97) regarding the effectiveness of fema’s egovernance tools in disaster mitigation. fema staff generally hold a more favorable view, indicating institutional confidence in the existing systems, whereas the affected community remains comparatively skeptical. this disparity highlights a critical disconnect between governmental perceptions and grassroots realities. while 63% global sustainability research global scientific research 11 of participants acknowledge the adequacy of government policies and their dissemination through electronic media, the community’s relatively lower ratings suggest gaps in trust, accessibility, and meaningful engagement. this aligns with oruonye et al. (2021), who observe that the presence of ict policy frameworks alone does not guarantee their effectiveness unless accompanied by practical, ground-level engagement strategies. notably, fema's reported 74% competence in identifying disaster-prone areas reflects a positive application of geospatial and risk assessment technologies. this is consistent with findings by gancarczyk et al. (2023), who emphasize the role of web-gis and decision support systems in mapping hazard-prone zones. however, they caution that the absence of localized implementation strategies and insufficient community involvement often undermines the full potential of such technologies. further compounding the issue is the widespread dissatisfaction (85% disagreement) among both staff and community members regarding compliance with ict-related safety protocols and the ineffectiveness of meteorological monitoring. these challenges likely stem from low ict literacy, weak infrastructural support, and a lack of community-centered approaches—factors that wolff (2021) identifies as central to the underutilization of participatory gis and citizen science in disaster governance. similarly, chauhan et al. (2020) highlight that effective geospatial vulnerability mapping must be accompanied by deliberate stakeholder inclusion and infrastructural readiness to yield practical results. in this regard, fema’s efforts, while technologically sound, remain constrained by implementation gaps that limit adoption, trust, and impact at the community level. to enhance disaster mitigation outcomes, fema must pivot toward a more inclusive, community-centric approach. this includes improving digital outreach, fostering ict literacy, and reinforcing early warning systems. without bridging the implementation and trust gap, even the most advanced e-governance tools will fall short of their intended impact. e-governance initiatives and preparedness efforts (pre-activity phase): the t-test shows a highly significant difference between fema staff (mean = 3.10) and community members (mean = 2.10) regarding the perceived role of e-governance in disaster preparedness, with a large mean difference of 1.00. fema personnel express strong confidence in ict tools and capacity-building efforts, while the affected community expresses notable dissatisfaction. a striking finding is the unanimous (100%) dissatisfaction from both groups concerning the adequacy of fema’s risk assessment and hazard analysis tools, and a similar unanimous concern about the early warning systems. this dual agreement on inadequacy signals systemic weaknesses that transcend perception gaps and point to real infrastructural and operational deficits. these findings are aligned with ogundele et al. (2013), who documented similar deficiencies in emergency agencies at the state level. moreover, the split perceptions on disaster monitoring (45% fema agreement vs. 73% community disagreement) further highlight insufficient disaster preparedness efforts at local and state levelsthis disparity underscores the need for inclusive planning and robust integration of community feedback into preparedness strategies, reflecting broader challenges observed in regions like nigeria’s south-south market areas. for instance, recent interventions by the edo state emergency management agency (edosema) illustrate how people-centred governance, through engagement with market associations, traditional leaders, and grassroots institutions, has enhanced disaster preparedness and risk communication in vulnerable local government areas (the nigerian observer, 2025). such participatory models not only validate the call for localized feedback mechanisms but also demonstrate their viability in addressing systemic deficits in emergency response and ict trust-building. recent empirical studies reinforce these concerns. for example, the inform@risk project in medellín, colombia (undrr, 2024), revealed that community trust and the effectiveness of early warning systems improve significantly when ict tools are codeveloped with local residents. this directly parallels the perception gap seen in fema’s preparedness systems. similarly, coulibaly et al. (2020) documented how an impact-based flood early warning system along niger’s sirba river successfully combined top-down hydrological models with bottom-up community thresholds, enhancing adoption and understanding. further evidence from nigussie et al. (2025) in ethiopia shows that global sustainability research global scientific research 12 involving communities in disaster data collection through citizen science substantially increases preparedness, system ownership, and local relevance. these studies validate the view that ict tools and risk frameworks are only as effective as their social adoption, contextual fit, and perceived reliability among end-users. fema should intensify investments in modern ict tools for hazard mapping, risk communication, and early warning systems. however, these tools must not be developed in isolation. the studies above affirm that capacity-building efforts must be complemented with inclusive, community-tailored training and participatory technology adoption programs. incorporating citizen voices into both the design and implementation stages of digital preparedness systems is crucial to building resilient and trusted e-governance frameworks. e-governance initiatives and response activities (post-activity phase): findings indicate a significant difference in perceptions of fema’s e-governance response capabilities (mean difference = 1.31), with fema staff rating their digital response mechanisms higher than community members. while a majority (64%) agree on the effectiveness of fema’s website for data storage and dissemination, concerns remain regarding the emergency hotline’s effectiveness and the promptness of online contact agents, with both groups expressing 64% disagreement about responsiveness. this divergence reveals critical weaknesses in real-time communication and emergency contact facilitation. this aligns with findings by kasim and oyerinde (2021), who observed that although nigeria’s national emergency management agency (nema) actively posted on facebook during disasters, it lacked proactive use of social media before emergencies, largely due to insufficient training and institutional policy gaps—mirroring the current findings on hotline inefficacy and slow agent response. additionally, the consensus on the inadequate presence of ict-equipped local response units in some area councils suggests institutional bottlenecks limiting decentralized disaster response effectiveness. this is consistent with tolessa et al. (2024), who found that while decentralization of disaster risk management in ethiopia’s oromia region enhanced local accountability, it remained hindered by coordination issues and limited capacity at the district level. despite progress in digital infrastructure, such accessibility and operational delays hamper rapid response, a vital phase where speed is essential. evidence from lagos during the covid-19 pandemic further supports this, as oni and peter (2022) show that social media platforms like twitter and whatsapp significantly enhanced real-time public engagement and trust when used actively by government agencies and influencers. this underscores the potential for fema to boost responsiveness and community engagement by adopting similar mobile and social strategies. e-governance initiatives and recovery efforts (post-activity phase): the significant mean difference of 1.04 between fema staff (mean = 2.83) and the community (mean = 1.70) highlights starkly contrasting views on the effectiveness of e-governance in recovery. both groups share dissatisfaction with the adequacy of ict personnel and field officers supporting recovery operations (49% fema disagreement, 59% community disagreement), signaling a critical shortage of skilled human resources. this concern aligns with sun et al. (2021), who argue that the effectiveness of disaster recovery is highly dependent on the proactive mobilization of trained human resources, including ict specialists. there is unanimous (100%) rejection of fema’s preference for manual search and rescue methods over technology-driven approaches, which runs counter to global trends promoting ict integration in recovery (lama & pradhan, 2018). this position is further supported by habibi, ivaki, and barata (2025), who demonstrate that drone-assisted emergency services and other automated technologies significantly outperform manual search and rescue efforts in speed, safety, and coverage, underscoring the urgency for fema to modernize. further, the division over the effectiveness of digital humanitarian and relief efforts, with 66% fema staff expressing agreement contrasted by 71% community skepticism, indicates serious concerns over transparency, equity, and trust. these concerns resonate with musa, magaji, and ibukuoluwa (2025), whose research in the nigerian context highlights the importance of integrating financial inclusion and digital tracking systems into humanitarian relief to ensure transparency and equitable distribution. these findings global sustainability research global scientific research 13 also reinforce oruonye et al. (2021), who emphasize that fema’s relief allocation is often reactive and tied to the magnitude of loss. the community’s distrust is compounded by differing opinions on digital transparency regarding donor and beneficiary disclosures, echoing ogundele et al.’s (2013) critique of opaque practices in state-level agencies. conclusion the study reveals a consistent and significant disparity between the perceptions of fema staff and the affected community regarding the effectiveness of fema’s e-governance initiatives across all phases of disaster management—mitigation, preparedness, response, and recovery—in the federal capital territory (fct). while fema personnel generally maintain a favorable view of the agency’s ict tools and strategies, the affected communities tend to express skepticism and dissatisfaction, particularly regarding the accessibility, timeliness, and adequacy of digital disaster management resources. during the mitigation phase, although fema staff believe that government policies and communication through e-governance platforms are sufficient and effectively disseminated, challenges remain in fostering citizen compliance with ict-based safety regulations. additionally, the agency’s capacity for real-time disaster forecasting and meteorological monitoring is still inadequate. to bridge this gap, fema should enhance community compliance and ict usage by initiating targeted education programs and participatory engagement strategies. such initiatives would improve understanding and adherence to mitigation policies, thereby increasing overall disaster resilience. in the preparedness phase, a striking divergence of views was observed. fema personnel expressed confidence in existing ict tools and staff training, whereas the affected communities unanimously viewed fema’s early warning systems and risk assessment mechanisms as ineffective. this gap underscores systemic weaknesses in both capacity and infrastructure. to address this, fema must prioritize upgrading its ict tools and early warning systems by adopting advanced risk analysis technologies, improving early warning communication channels, and conducting continuous training for personnel. these improvements will help align internal confidence with public trust and expectations. regarding the response phase, fema’s digital infrastructure, particularly in data storage and dissemination through websites, has shown encouraging progress. nevertheless, concerns persist about the responsiveness of emergency hotlines, online contact systems, and the adequacy of local response units. these weaknesses point to limitations in the coordination and accessibility of response efforts. improving digital infrastructure accessibility and establishing well-equipped, ict-enabled response units across all area councils will significantly enhance timely disaster response and reduce the disconnect between institutional performance and community perception. in the recovery phase, both fema staff and community members voiced concerns about inadequate ict personnel and continued reliance on manual methods for search and rescue operations. moreover, a lack of trust in fema’s digital humanitarian efforts and perceived transparency deficits hinder effective post-disaster recovery. addressing these challenges requires the integration of transparent digital monitoring and reporting systems for relief distribution. furthermore, adopting technology-driven recovery methods in place of manual processes will improve efficiency, accountability, and community confidence in fema’s recovery operations. in summary, the findings highlight the urgent need to improve the integration of ict across fema’s disaster management framework. this should be supported by increased investment in digital infrastructure, inclusive stakeholder engagement, enhanced training programs, and a commitment to transparency. doing so will not only close the perception gap between fema personnel and the communities they serve but also strengthen institutional credibility and public resilience in the face of recurring disasters. global sustainability research global scientific research 14 declaration acknowledgment: n/a funding: n/a conflict of interest: n/a ethics approval/declaration: n/a consent to participate: n/a consent for publication: n/a data availability: n/a authors contribution: n/a references abasilim, u. d., gberevbie, d. e., & ifaloye, o. r.
