Impacts of Climate Change and Population Pressure on Food Consumption Patterns and Economic Consequence

Abstract There are discernible trends in severe food insecurity prevalence among the adult population in sub-Saharan Africa. This study delves into the complex interactions of climate change impacts, agricultural factor productivity and changes in population growth, which together exacerbate the issue of food insecurity. To comprehend these intertwined effects on rural and urban food insecurity, we employed the Rural Investment and Policy Analysis data and Computable General Equilibrium modelling system developed by the International Food Policy Research Institute. Our findings revealed a decline in urban food consumption associated with increased urban population and decreased agricultural total factor productivity. However, we observed a slight increase in real consumption for rural households. Our analysis indicates a contraction in the economy and a disruption in the volume of international trade. This research contributes valuable insights into the multifaceted challenges sub-Saharan Africa faces in its pursuit of food security, enabling policymakers to construct informed decisions and design effective interventions.
