Maize is more vulnerable to climate change than had previously been thought, Mar. 13, 2011. Scientists found that under drought conditions, a 1 decree C rise in temperature could cut yields from 3/4 of Africa's maize-growing regions by at least 20 percent

"To survive the droughts, wars and other major causes of famine, Africa must embrace technologies that enable it to produce more, better food with less effort.
Indeed, without the advances in molecular biology and other scientific fields that occurred in the second half of the twentieth century, African nations would be much worse off than they are now. Without this Green Revolution, which enabled developing nations to import cheaper grains and grow high-yield seed varieties, analysts estimate that crop yields in developing countries would have been 23.5% lower and prices between 35% and 66% higher in 2000. Caloric intake would have dropped by up to 14.4%, and the proportion of malnourished children would have increased by nearly 8%. Put another way, the Green Revolution helped to raise the nutritional status of up to 42 million preschool children in developing countries (758–762; 2003)...." and Science 300,
