Exploring the relationship between extreme weather events, urbanization, and food insecurity: Institutional quality perspective

Abstract

This study examines the potential for institutional quality to address Africa's trilemma of food insecurity, rapid urbanization, and extreme weather events.Using a two-stage least squares regression analysis of 28 African countries between 2012Q1 and 2021Q4, our results suggest that extreme weather events have a significant negative impact on food security, particularly in urban areas.We found that institutional quality can have a significant positive impact on food security and can mitigate the negative effects of extreme weather events on food security. Our study also decomposed the food security index into its four components and found that extreme weather events negatively affect the affordability, availability, quality, and natural resource resilience of food. The findings are robust to the use of the feasible generalized least squares and panel-corrected standard errors estimation techniques.The policy implications of our study are significant, as our findings suggest that central governments can take practical steps to minimize the impact of extreme weather events on food security. Specifically, investing in disaster preparedness, improving infrastructure, and promoting agricultural development can all help improve food security. Additionally, improving institutional quality can be an effective way to mitigate the negative impact of extreme weather events on food security.
