Abstract: Climate change has a dual impact on food security, with direct consequences related to temperature levels and water availability in agriculture, and indirect effects stemming from its influence on disease vectors and pests. This research delves into the economic ramifications of climate change on food security within Sub-Saharan Africa (SSA). The study employs panel data encompassing all SSA nations to scrutinize the repercussions of temperature and precipitation on food security. Specifically, the analysis leverages the coefficient of variation to assess their influence on food security. The findings of this investigation reveal that variations in both temperature and precipitation have an adverse impact on food security. These climate-related variables affect food security by directly impinging on food production and indirectly affecting other indicators of food security. In light of these results, the study advocates for the implementation of ecosystem management and enhancements in production systems. Moreover, it underscores the significant detrimental effects of climate change on food security in the SSA region. To counter these impacts, the study proposes the development of effective land use policies, the conservation of natural resources, the adoption of optimal agronomic practices, and the maintenance of the population at an appropriate level within the region.
