A recent study published in Nature Climate Change shows that six of nine staple crops in sub-Saharan Africa are expected to be able to continue to be cultivated in a warmer climate. Three crops, however, maize, beans and bananas, will most likely no longer be viable in the new climate and will have to be replaced by other crops or other varieties that do better in warmer temperatures. These steps are necessary to provide food security for the population who lives there, and some steps in the transition will need to be made as soon as 2025, according to the researchers. They estimate that up to 60 percent of the area where beans are produced will become non-viable for future production while 30 percent of the area now producing bananas and maize will need to transition to other crops because of the warmer climate.
