Abstract：
Environmental pollution has aggravated the climate change issues posing unusual challenges to the survival and growth of humanity, including extreme weather, loss of species, and sustainability of the ecosystem in developing countries. Unlike previous studies, this paper adds new dimension to the literature by incorporating corruption into agriculture production-environment nexus. This study adds new dimension to the literature by examining corruption, agriculture, and renewable energy on CO2 emissions. The study therefore examines the effects of governance (corruption) and agriculture production on CO2 emissions in 20 countries in Africa from 1990 to 2019. The study employed recent panel econometric approach which accounts for cross-sectional dependence in the variables. The findings of the fixed effect model and panel dynamic ordinary least squares (PDOLS) show that forest and renewable energy consumption decrease CO2 emissions. However, corruption, agriculture production, export, and urbanization escalate CO2 emissions in African countries covered in the paper. Moreover, the Dumitrescu-Hurlin Granger causality indicates a bidirectional causality between agriculture production and CO2 emissions, renewable energy use, agricultural output, and forest. Also, unidirectional Granger causality runs from corruption to forest and agriculture production. On these premises, consented efforts by governments should be made to support good institutions in order to promote good governance to avert pervasive consequences of corruption on the environment.
摘要：
环境污染加剧了气候变化问题，给人类的生存和发展带来了不同寻常的挑战，包括极端天气,物种流失,以及发展中国家生态系统的可持续性。与以往的研究不同,本文通过将腐败纳入农业生产与环境的关系，为文献增加了新的维度。这项研究通过考察腐败，为文献增加了新的维度，农业,和可再生能源对二氧化碳排放的影响。因此，该研究考察了1990年至2019年非洲20个国家治理（腐败）和农业生产对二氧化碳排放的影响。这项研究采用了最近的面板计量经济学方法，该方法考虑了变量的横截面依赖性。固定效应模型和面板动态普通最小二乘法（PDOLS）的结果表明，森林和可再生能源消费减少了CO2排放。然而,腐败,农业生产,export,和城市化加剧了本文所涵盖的非洲国家的二氧化碳排放量。此外，Dumitrescu-HurlinGranger因果关系表明农业生产和二氧化碳排放之间存在双向因果关系，可再生能源的使用,农业产出,和森林。此外，单向格兰杰因果关系从腐败到林业和农业生产。在这些前提下，各国政府应共同努力支持良好的机构，以促进良好的治理，以避免腐败对环境的普遍影响。
