ABSTRACT

Coral reefs are ecologically important as they provide shelter and life support 
to the marine resources, sustain ecological balance, and human existence. Coral 
reef degradation is an ecological problem that needs human intervention and 
is considered a school’s social responsibility. The USANT College of Maritime 
Education and College of Engineering and Architecture rationalized social 
responsibility in partnership with the Bureau of Fisheries and Aquatic Resources 
(BFAR) and the Philippine Coast Guard Auxiliary (PCGA) and the barangay 
Pararao, Balatan, Camarines Sur, Region V, Philippines. The researcher used the 
Impact Evaluation and Study Design substantiated by an FGD and Underwater 
Diving of BFAR marine specialists to ascertain the impacts of the artificial coral 
reef project in drawing environmental awareness and determine the actual effect 
of the artificial coral reefs as shelters and spawning sites of fishes. Findings reveal 
that communal participation in safeguarding the vicinity of the reefs emanating at 
the barangay level is evident; the community folks had gained an understanding 
of the role of coral reefs in the ecosystem and school of fishes shoaled in the 
vicinity. Thus, this coral reef project drew positive attention, reduced minimalistic 
attitudes, and increased environmental awareness. The artificial reefs now serve as

INTRODUCTION

Coral reefs are some of the most productive ecosystems on earth that support 
the marine living organisms at sea that reverberates to the survival and growth 
of other living organisms on earth. Also known as the rainforests of the sea 
(Shannon, 2018; Swart, 2013), fishes, corals, lobsters, seahorses, sponges, and 
sea turtles are only a few of the thousand creatures that rely on reefs for their 
survival, according to the National Oceanic and Atmospheric Administration, 
(NOAA, 2017).

“Reefs at Risk Revisited” (2011) reported that 75% of the coral reefs are at risk 
from local and global stresses. Ninety (90%) of the coral reefs will be in danger by 
2030 and nearly all of them by 2020. The drastic increase in temperature (Jokiel, 
2016; Banaguas, 2014) siltation, (Banaguas, 2014; White, Vogt, & Arin, 2000) 
and the impacts of long terms biophysical conditions (Banaguas, 2014), the 
accumulated human impacts and the combined with current fishing pressures 
and devastating coral mortality in 2015, have resulted in a degraded coral reef 
ecosystem state at Puakō in West Hawaiʹi. Changes to resource management are 
needed to facilitate the recovery of ecosystem functions and services (Weijerman 
et al. 2018).

In the Philippines, overfishing, destructive fishing methods, and 
sedimentation have damaged and destroyed many reef areas, White, Vogt, 
& Arin, 2000). A study revealed that the manifestations of organic nutrients 
discharged from streams adjacent to the populated areas in Palau may cause a 
shift in the balance of corals and algae found in shallow barrier reefs, which can 
be aggravated by intense agriculture, land degradation, and overfishing, (Colin, 
2009).

On this note, the responsibility of rehabilitating and mitigating the impacts 
of coral reef degradation and how each individual from all walks of life will 
be a potent factor should be the concern of the government, non-government 
organizations, schools, and families, and community. Schools can share the 
greatest responsibility as it caters to educating the minds, teaching the hearts, 
and making a difference (Soriano, 1995).

Schools contribute in two ways; rehabilitative and educative. The former 
deals with the artificial reef building activity while the latter pertains to the 
continuous environmental teaching of the community folks who are direct 
beneficiaries of the project. 

The University of Saint Anthony (USANT) is not only concerned with 
providing quality education to the students but also in reaching out to help the 
marginalized sectors of the community through its corporate social responsibility 
initiatives and community extension projects. USANT’s community services are 
not only limited to its adopted barangay but to other barangays, municipality, or 
towns within the Province of Camarines Sur it serves. It is in this context that the 
College of Maritime Education and the College of Engineering and Architecture 
decided to rationalize their goals through the Build an Artificial Reef Project in 
Pararao, Balatan, Camarines Sur. The project idea emanated from the people of 
BFAR; Region V coral reefs are diminishing. The College of Maritime Education 
and the College of Engineering and Architecture, in coordination with the 
Community Extension Service (CES) Office, decided to conduct an ocular 
inspection in the vicinity to be able to gain an idea on how and what project will 
be implemented. 

The group then found out that the coral reefs in the said place started to 
vanish. It is in this perspective that the group decided to help the community by 
building an artificial coral reef to help the small fisherfolks to earn a living. The 
College of Engineering and Architecture also envisioned to provide livelihood 
programs for the people in the place while waiting for the reefs to grow to 
temporarily address the needs of the people in the place. The said project was 
realized with the help of the Bureau of Fisheries and Aquatic Resources (BFAR) 
and the Philippine Coast Guard Auxillary (PCGA).

 
FRAMEWORK

The framework displays the elements that contribute to the preservation, 
rehabilitation, and survival of coral reefs towards sustainable development. The 
political, legal, technological, economic, environmental, social, and educational 
factors should lead towards a holistic approach to ecological conservation and 
balance.

Figure 1. Conceptual Framework

There is a need to strike a balance of the factors that affect coral reefs because 
they are interrelated and symbiotic. The PESTLE analysis, formerly PEST 
analysis, (Morrison, 2007) is a framework or tool that can be used to analyze 
and monitor the macro-environmental factors that have a profound effect on 
an organization’s performance. In addition to PESTLE, there is another E that 
stands for Education, hence a new acronym, which is PESTLE that applies to the 
current study. The researcher believes that the political, economic, technological, 
environmental, social, and legal factors encompass the survival of the coral reefs. 
Any government policies created, be it local or national, leadership styles and 
priorities, the employment, demographics, education levels, cultural trends and 
lifestyles, technology, industrialization, legislations, laws, and ordinances are all 
external forces that may directly or indirectly strike on ecological balance. As 
water seeks its level, all the impacts of the policies, processes, and practice will 
succumb to the ocean, as water flows down to seek its level.

OBJECTIVES OF THE STUDY

This study aims to: Ascertain the degree of response of the community folks 
in the community extension project; determine the impacts of the artificial coral 
reef project as perceived by the fisherfolks in Balatan, Camarines Sur, and by the 
divers from the Bureau of Fisheries and Aquatic Resource, (BFAR), Philippines; 
draw recommendations from the fisherfolks as to how the community can help 
conserve marine resources.

 
METHODOLOGY

 Research Design
The study utilized the Impact Evaluation and Study Design in order to 

measure the impact of the Artificial Coral Reef Rehabilitation Project of the 
University of Saint Anthony, Iriga City, Philippines, following three steps: 
(1) defining intervention- answers the question: “what are we evaluating,” (2) 
measuring performance – answers “what and how to measure,” (3) attributing 
cause- factual or counterfactual.

According to World Bank, as stated by the (Ng, 2013), Impact Evaluation 
aims to (a) assess changes in the well-being of individuals, households, 
communities or firms that can be attributed to a particular project, program or 
policy (b) provides feedback to help improve the design of programs and policies. 
The impact measures how well the program delivers an intervention and the 
outcomes. Impact evaluation is making causal inferences about the effect of a 
program on a target population.

Steps in the determination of impact contextualized by the researcher: 
observation, inquiry, actual/factual observation, consultation, and evaluation. 
The observation was conducted to determine the response of the community 
folks, their extent of participation, and the evidence of actual and communal 
participation.  

An inquiry was made to ascertain whether the attitudes and behaviors of 
the community folks have changed before and after the implementation of the 
project. The factual observation was carried out in the actual diving of experts 
from the Bureau of Fisheries and Aquatic Resources (BFAR) to determine the 
effects of the artificial reef environment. Consultation with experts from BFAR 
as to the technical aspect; the Community Officials on the environmental, social, 
economic, political, and cultural factors and the members of the academe for

educational implications. Evaluation of the project measures the outcomes 
according to the degree of participation of the community folks and the actual 
effect of the artificial reef as an artificial home of the living organisms at sea.

Plate No. 1 Coral Reef Model

The group tried to identify first a coral reef model, which became the pattern 
in building the reef. The said model is shown in Plate No. 3. From the above 
model, the USANT group started to build the reef by having a dry run on how 
the reef will be arranged at the seabed as shown in Plate no. 4

After the demonstration, the students and volunteer residents enthusiastically 
started to dismantle the reef to be loaded in the boat in preparation for the actual 
reef-building on the seabed. The building of the reef was done by two persons 
but was assisted by the men who boarded the boat to assist those responsible in 
loading the hollow blocks in the sea. The hollow blocks were unloaded before 
they started building the reef underwater. The divers were equipped with diving 
paraphernalia.

Plate No. 3 Building the Coral Reefs

In May 2019, two more modules were installed in addition to the six 
modules planted in 2017. Surprisingly, the BFAR divers revealed the presence of 
a school of fishes in the artificial reef areas. The environment is calm and green 
as several varieties of fish were observed shoaling, such as  tulingan  and  Sweet 
Lips or Plectorhinchus. These fishes find refuge in the artificial reefs as divers find 
their way into the reefs for ocular inspection.

RESULTS AND DISCUSSION

The support of the barangay folks was immense as their presence was evident 
in all meetings, consultations, preparation, and actual installation of the artificial 
reefs or modules.

According to one of the community folks, expressing with gratitude, 

She is thankful for the community extension project that serves as an eye-opener 
for the people in the community on the plight of the sea, the low fish catch, overfishing, 
and siltation, and coral reef destruction.

A year after the reefs were built, the key persons on the “build a reef project” 
visited the place and found out that algae and mosses have become evident. One 
of the residents commented: “The fisherfolks have observed fishes shoaling in 
the vicinity of the artificial reefs, indicating that marine life is starting to rebuild 
itself.”

 As commented by Norma Alamo, a resident of Pararao, a public school 
teacher, she overheard from the small fishermen that the “build a reef project” 
will be of great help, especially to the fisherfolks who are entirely dependent on 
the marine resources. Mrs. Alamo disclosed further that the small fishermen are 
hoping that more artificial reefs will be constructed and installed to put back life 
into the sea. 

Moreover, based on FGD of the community folks who themselves are 
fishermen, the impact of the artificial reef project is seen on the change of 
attitudes of the fisherfolks on marine conservation and protection. People now 
are more aware of the effects of marine pollution on coral destruction, illegal 
fishing, and the long term benefit of artificial reefs on sustainable development.

Livelihood programs for women, environmental teaching for the youth, 
clean-up drive, advocacy programs are a few of the projects that will be further 
undertaken by USANT based on the recommendations of the local folks. 
Regular visits, documentation using an underwater camera, and installation of at 
least two more modules are the upcoming projects of the USANT community 
extension office in response to the mandate of higher education to deliver quality 
extension projects towards inclusivity and sustainable development.

 
CONCLUSIONS

Community involvement is pivotal in the effective and efficient delivery of 
community extension projects; otherwise, this project will be a failure. People’s 
stewardship, discipline, and collective efforts combined with continuous 
engagement with partners are key elements of sustainability. The impact of the 
project is long-term, but reasonable and obvious results are observable in the 
community folks’ overt behaviors, actual observations, and underwater evidence 
divulged by authorities. Community initiatives such as clean-up drive, women 
empowerment programs, income-generating projects, environmental awareness 
campaigns, and a strong political will from the barangay folks, youth participation 
with parental guidance are essential elements.

TRANSLATIONAL RESEARCH

The findings of the study can be translated into a documentary manual that 
will provide an updated record of the existing marine life in Balatan, Camarines 
Sur. It will also raise awareness of the local folks and enhance the partnership of 
the university to the different stakeholders (i.e., BFAR, Phil. Coast Guard). The 
impacts of the artificial reefs may not be similar to the natural reefs, but their 
presence can certainly shelter the marginal fishes and become a fish sanctuary 
towards sustainable development.

ACKNOWLEDGMENTS

The research would like to express his gratitude to the community folks of 
Pararao, Balatan, Camarines Sur, the University of Saint Anthony Community 
headed by its President and Chairman of the Board, Atty. Santiago D. Ortega, 
Jr, and Atty. Butch SD. Ortega, Jr. Engr. Editha Dacara, Dean Carlos Epres, Dr. 
Marilou Tino, Mrs. Evelyn De Villa, PCGA, BFAR, faculty, students, and the 
participants who gave their all in the realization and optimization of the project. 
All your efforts shall pave the way towards a sustainable environment now and 
in the future.
