The current period marked by addressing environmental sustainability challenges and the instability of government institutions has heightened the issue of food security, especially in developing countries as they work towards achieving Zero Hunger as highlighted in the Sustainable Development Goals. To assess the effect of environmental sustainability and government institutions on food security in West Africa with data from 1990 to 2021, two models have been deployed. The Generalized Method of Moments was deployed as the main model and while Two-Stage Least Squares was used as the robustness check. The findings of the study reveal that carbon emissions which represent environmental sustainability has no direct significant effect on food security, while government institutions has negative effect on food security. The study also reveals that income and urbanization promote food security, while renewable energy and population growth reduce food security. The findings of the study could be a reflection of the current political instability and attitude towards tackling carbon emissions mitigation in the region. Government institutions are encouraged to exercise authority without fear to implement policies that would encourage food security and restrict the use of high-emission technologies.
当前时期面临着环境可持续性挑战和政府机构不稳定的问题,这使得粮食安全问题更加突出,特别是在发展中国家,它们正在努力实现可持续发展目标中提出的“零饥饿”目标。为了评估环境可持续性和政府机构对西非粮食安全的影响,本研究利用 1990 年至 2021 年的数据建立了两个模型。广义矩法被用作主要模型,而两阶段最小二乘法被用作稳健性检验。研究结果表明,代表环境可持续性的碳排放对粮食安全没有直接的显著影响,而政府机构对粮食安全有负面影响。研究还表明,收入和城市化水平促进了粮食安全,而可再生能源和人口增长则降低了粮食安全。本研究的结果可能反映了该地区当前的政治不稳定和应对气候变化的态度。政府机构应在不畏惧的情况下行使权力,实施鼓励粮食安全和限制高排放技术使用的政策。
