Research that exploits the results of historical crop trials indicates that Africa's maize crop could be at risk of significant yield losses. Nonlinear heat effects on African maize as evidenced by historical yield trials David B. Lobell, Marianne Bänziger, Cosmos Magorokosho and Bindiganavile Vivek An analysis of over 20,000 historical African maize trials suggests the crop will better cope with climate change under rain-fed management. For a 1 °C temperature rise, optimal rain-fed conditions would mean 65% of maize-growing areas in Africa would be likely to experience yield losses, compared with 100% under drought conditions. 13 Mar | Nature Clim.
