The impacts of climate change on agricultural systems in West Africa have been analyzed extensively. However, few studies have focused on livestock systems. Using export data for the period 1996–2017 and climate data for two major cattle suppliers (Mali and Burkina Faso) and one net importer (Côte d’Ivoire) in West Africa, we estimated a gravity model of temperature and cattle trade. Our study provides findings on the impacts of climate change on cattle supply. Indeed, we found that climate shocks in some major Sahel cattle-exporting countries, i.e., Mali and Burkina Faso, can affect the supply of a coastal import country, such as Côte d’Ivoire. Specifically, the study supports findings that a temperature increase in the Sudanian region of the Sahel induces a significant decrease in cattle trade flows. We found, as an example, that a 0.3 °C global increase in temperature could decrease cattle trade flow by 25 …
