AEC 2012 - Rainfall Shocks, Food Prices Vulnerability and Food Security-Evidence for Sub-Saharan African Countries
This paper investigates the effects of rainfall shocks caused by climate change on food security in sub-Saharan Africa (25 countries) compared to developing countries (77 developing countries) over the period 1960-2008. For this purpose, we use panel data and apply econometric methods. Results suggest that rainfall volatility is a factor of food insecurity (through food supply reduction) in developing countries. Moreover, the adverse effects of rainfall shocks are higher in sub-Saharan African than other regions. Second the adverse effects of climatic shocks are exacerbated for countries that are vulnerable to food prices shocks.
