Abstract: The resurgence of food insecurity in Sub-Saharan Africa during the past decade highlights the need to comprehend the phenomenon within a framework that includes all economic agents in these times of intensification of climate change. Thus, this paper, using a Dynamic Stochastic General Equilibrium (DSGE) model, analyzes the effects of climate shocks occurring in agricultural and non-agricultural sectors on household food security in Sub-Saharan Africa, while determining optimal monetary policy responses to mitigate these adverse effects. Findings highlight that climate shocks affecting the non-agricultural sector are more detrimental to long-term household food security than those affecting the agricultural sector, particularly for urban households. To mitigate these effects, flexible policies targeting food price inflation and headline inflation seem appropriate for rural and urban households, respectively. Nevertheless, in the absence of political and social pressure, flexible headline inflation targeting is optimal for mitigating climate shocks effects on Sub-Saharan Africa's food security.
