Abstract: This chapter examines the impact of self-reported drought and flood occurrences on farm income in sub-Saharan Africa, using panel data from four countries covering the period 2009 to 2016. The results reveal robust and negative effects of drought on farm income, with particularly strong and heterogeneous impacts across income sources. Specifically, drought reduces crop net income by 9.8% and total agricultural net income by 5.9%. These findings underscore the vulnerability of farming systems to drought shocks and highlight the crucial role of efficient input use and dependable irrigation access in reducing drought-related income losses. In contrast, flooding shows no statistically significant effects, suggesting the need for further research to better understand the pathways through which floods influence agricultural outcomes.
