Global food production must respond to the demands of a growing world population, and to the hazards of climate change. Higher temperatures, unpredictable rainfall and weather patterns, changes in growing seasons, increased occurrences of drought and extreme weather events will exert a greater strain on agriculture. These changes are forecasted to have a high impact in Africa. Warming in Africa should be greater than the global average, with decreasing precipitation leading to higher...
