Commodity-based economic growth that has driven Africa’s development in the past decades is now in jeopardy owing to the impact of climate change on natural resources and agricultural commodities. The effects of temperature on the aggregated macroeconomic productivity in poor countries have been found to be linearly related to an increase in temperature, primarily through the effects of temperature on workers and crops. Lobell and others demonstrated the non-linearity between warming and yield relationships in African maize, in particular how the final yield of maize under rainfed conditions was reduced by 1 per cent for every day spent above 30 C, even by just one additional degree. Through those findings, it was underscored that approximately 65 per cent of Africa’s maize-growing areas will experience temperature-induced yield losses at 1C of warming, even under optimal rainfed management. The main objective of the present brief is to draw attention to the opportunities that exist for harnessing agricultural production and regional trade to safeguard food security in Africa under the impact of climate change.
