Abstract

Abstract This paper examines whether an integrated farm that owns both crops and livestock is more resilient under global warming than a specialized farm in crops. Using around 9000 farm surveys across Africa, we explore how farmers choose one of the farm types and how the net revenue of each type varies across the range of climate in Africa. The results indicate that an integrated farm increases in number while a specialized farm decreases across Africa under climate predictions for 2060. The relative profitability of each system against each other also changes. An integrated farm becomes relatively more profitable over specialized farms half a century from now. The impacts of climate change on integrated farms range from 9% loss to 27% gain depending on climate scenarios. Behavioral models can capture portfolio diversification benefits that agro-economic models cannot measure.
