Heterogeneous impact of extreme temperatures on household farms: evidence from Sub-Saharan Africa

Abstract

This paper investigates the heterogeneous impact of extreme heat on household farms in low-income countries. Our source of heterogeneity is farm size, as it has been shown to matter for productivity and agricultural practices. Using a large panel dataset from Uganda, Tanzania, Ethiopia, and Malawi, we show that extreme heat reduces agricultural output and food security, independently of farm size. We do find, however, that some responses to temperature shocks are different, e.g., small farms increase land use. These findings suggest that all household farms are vulnerable to the negative impact of climate change, even the largest ones.
