Abstract：
The aim of this study is to provide an empirical answer to the question of whether nexus exists between climate change and sustainable agricultural growth in nine (9) countries within the Sahel region between 1990 and 2020. The study utilized Panel ARDL and Pairwise Dumitrescu Hurlin Panel Causality Tests to arrive at the following conclusions; firstly, the climate change orchestrated by change in rainfall is a very prominent factor causing reduction in sustainable agricultural growth in the Sahel region. One way feedback relationship flows from sustainable agricultural growth to greenhouse gas emission. In the light of the above, this study recommends that, in addressing the adverse effects of change in rainfall on agricultural sustainability, the policymakers in the Sahel region in particular and Africa as a whole should embark on a policy mix by embanking on mitigating policy response towards ensuring sustainable agricultural production via irrigation which is the best mode of water provisions without causing negative spilliovers on the environment. Also, the policymakers should be proactive by embarking on policies and programs that would build the resilience and adaptation of the region ahead of the future adverse effects of agriculturally induced climatic change.
摘要：
这项研究的目的是为1990年至2020年间萨赫勒地区九（9）个国家的气候变化与可持续农业增长之间是否存在联系提供经验答案。本研究利用面板ARDL和配对DumitrescuHurlin面板因果关系检验得出以下结论：首先，降雨变化导致的气候变化是导致萨赫勒地区可持续农业增长减少的一个非常突出的因素。从可持续农业增长到温室气体排放的一种反馈关系。根据上述情况,这项研究建议，在解决降雨变化对农业可持续性的不利影响方面，特别是萨赫勒地区和整个非洲的决策者应着手制定政策组合，通过灌溉来减轻政策反应，以确保可持续的农业生产，这是最好的供水方式，而不会对环境造成负面影响。此外，政策制定者应该积极主动，着手制定政策和计划，在农业引起的气候变化的未来不利影响之前，建立该地区的复原力和适应能力。
