East Africa has a substantially greater rate of food insecurity than other regions of the world. Scenarios of climate change and other macroeconomic variables are important contributors to food insecurity in East Africa. Using data spanning from 1990 to 2020, this study looked into the influence of carbon dioxide (CO) emissions, economic growth, population growth, trade openness, and agricultural employment on food security in the East Africa. The fully modified ordinary least square (FMOLS) and dynamic ordinary least square (DOLS) models were used in this study. The heterogeneous panel cointegration test's findings indicated that the study variables have an equilibrium long-term connections. The estimation findings from the FMOLS and DOLS models showed that an increase in CO emissions increases food security in the East Africa over the long term. According to other findings, long-term food security is positively impacted by economic expansion, population growth, trade openness, and employment in agriculture. However, trade openness has a detrimental long-lasting effect on food security. Future research directions, research limitations, and policy implications are discussed.
东非的粮食不安全率比世界其他地区高得多。气候变化情景和其他宏观经济变量是东非粮食不安全的重要促成因素。本研究利用1990年至2020年的数据，探讨了二氧化碳（CO）排放、经济增长、人口增长、贸易开放度和农业就业对东非粮食安全的影响。本研究使用了完全修正普通最小二乘法（FMOLS）和动态普通最小二乘法（DOLS）模型。异质面板协整检验的结果表明，研究变量存在均衡的长期联系。FMOLS和DOLS模型的估计结果表明，从长期来看，CO排放的增加会提高东非的粮食安全。根据其他研究结果，经济扩张、人口增长、贸易开放度和农业就业对长期粮食安全有积极影响。然而，贸易开放度对粮食安全有长期的不利影响。本文还讨论了未来的研究方向、研究局限性和政策含义。
