Crop response to climate change in southern Africa (Zinyengere, N. et al. / SADC)

Concern over future food security in southern Africa has led to various studies that assess the impact of climate change on crops in the region. This study reviewed and consolidated results from 19 recent studies which quantitatively project the impact of climate change on crops for the 21st century in southern Africa. Studies were assessed for their reporting and recommendations concerning adaptation and CO2 fertilisation. Results suggest that the aggregate impact of climate change on crops in southern Africa will be negative. Maize yields are projected to decline on average by 18%. The collective impact of climate change on all crop yields shows a median decline of 11% and−14% respectively under process-based and statistical methodologies. Median impacts show declining crop yields through the 21st century.
