There are now many studies which suggest that rising temperatures and reduced rainfall will make the farming of many African staples more difficult. So there is nothing particularly new or surprising about a new CGIAR study that says yields of maize, wheat and rice may significantly decrease as a result of climate change.
Among other things, the study says that in Africa maize output may decline by 10 to 20%. Irrigated wheat and rice could drop by 13 and 15% respectively in developing countries.
Yet just a few weeks ago there was a much publicized suggestion that Africa could and should be growing more wheat.
What should African countries do about wheat in light of these seemingly clashing findings?
