By 1890, the world agricultural economy had taken shape, accompanied by complex changes in patterns of labour mobility, capital flows, ecology and technology. Food no longer came from nearby villages or towns, but from thousands of miles away. The last 50-100 years have seen dramatic changes in agricultural production and productivity, driven in large part by public and private investment in agricultural re- search, with a profound impact on the world’s poor in par- ticular [1]. In this issue, we begin by discussing the further devel- opment of agriculture in Europe, under conditions of post- war recovery like in Ukraine [2]. In particular, the integra- tion of the agricultural sector into the global economic space. Then, in the next three articles we analyse the prob- lems in the agricultural development of the African coun- try Ethiopia, such as one of the main obstacles to livestock production in South Omo—the lack of information on the state of production and commercialisation of improved Panicum grass [3]; the essential role of rural women in ag- ricultural activities to reduce poverty and food insecurity. The research focused on gender equity in rural women’s access to and control over agricultural and rural household resources [4]; as well as the cattle market transport facili- ties, legal cattle market promotion centres, credit facili- ties, and cattle feeding and health improvement strategies [5]; and on the value chain of Macadamia nuts (Macadamia integrifolia) technical efficiency among the small-scale farmers in Zimbabwe in the article by Dr. Wellington Bandason et al. [6]. Finally, accelerating climate change could further cut crop yields, especially in the world’s most food-insecure regions, therefore, an article by Dr. Ganesh Raj Joshi and Dr. Ramchandra Bhandari assesses perceptions of climate change in the Asian country Nepal and identifies factors influencing the adoption of comple- mentary irrigation practices [7]. COVID-19 had some impact on the development of the world agricultural economy and food security. The main effect of the pandemic was to exacerbate the existing de- http://dx.doi.org/10.36956/rwae.v3i4.803 http://dx.doi.org/10.36956/rwae.v3i4.803 mailto:1225zkl@sohu.com 73 Research on World Agricultural Economy | Volume 03 | Issue 04 | December 2022 clining trend in food security. Food insecurity increases considerably in countries in Asia through income shocks rather than prices effects [8]. Conflict of Interest There is no conflict of interest.
