The Corn Belt could face yield declines of more than 25 percent by mid-century as climate change takes hold.
The report, Advancing Global Food Supply in the Face of a Changing Climate, urges the Obama Administration to step up research funding – especially in developing countries – to help make up a projected gap in future food supply.
Those rising seas would displace millions of people from low-lying coastal areas - and wipe out rice-growing areas across Asia, Gerald Nelson, a University of Illinois economist and author of Thurday's report, said. In terms of absolute land loss, China would be at risk of losing more than 3 million hectares (7.4 million acres). Vietnam, India, Bangladesh, and Myanmar could lose more than 1 million hectares (2.5 million acres), the report said.
"The question is: 'are we doing the right kind of research at our universities, at the department of agriculture, or in the private sector to deal with those changes? We need more and more applied research to help us move those numbers up. That is the real challenge for scientists."
"We have got to figure out how to get plants to continue performance when average temperatures go up, and we don't know how to do that," Nelson said. "We need 60 percent more food generally, and this will make it harder to get there," he said.
