Climate Change Will Threaten Key Crops Across Sub-Saharan Africa

Climate change’s rising temperatures and more frequent and intense droughts could leave parts of sub-Saharan Africa unable to grow staple crops such as maize, bananas, and beans by the end of the century, according to new research
published Monday in the journal Nature Climate Change. Up to 60 percent of bean-producing areas and 30 percent of maize and banana farms could become unviable by 2100, and farmers should start growing more climate change-resistant crops, improve irrigation systems, or switch to raising livestock, the scientists said. “Agriculture and farming are critical not only for the livelihoods of farmers but also more broadly for the diets of the region’s population,” said
Julián Ramírez-Villegas, a scientist at the International Center for Tropical Agriculture (CIAT) and lead author of the study. “Unless timely adaptation actions are taken, we’re looking at a bleak picture in terms of food security and poverty throughout many areas of sub-Saharan Africa.”
