IPCC projections suggest that warming scenarios risk having devastating effects on crop production and food security.
Key risks to agriculture include reduced crop productivity associated with heat and drought stress and increased pest damage, disease damage and flood impacts on food system infrastructure, resulting in serious adverse effects on food security and on livelihoods at the regional, national and individual household levels.
By the middle of this century, major cereal crops grown across Africa will be adversely impacted, albeit with regional variability and differences between crops.
Under the worst case climate change scenario, a reduction in mean yield of 13% is projected in West and Central Africa, 11% in North Africa, and 8% in East and Southern Africa. Millet and sorghum have been found to be the most promising crops, with a yield loss by 2050 of just 5% and 8%, respectively, due to their greater resilience to heat-stress conditions, while rice and wheat are expected to be the most affected crops with a yield loss by 2050 of 12% and 21%, respectively
