A report has warned that people in Africa and Asia could also become destitute as staple more than double in price by 2050 as a result of extreme temperatures, floods and droughts that will transform the way the world farms.
As food experts gather at two major conferences to discuss how to feed the nine billion people expected to be alive in 2050, leading scientists have told the Observer that food insecurity risks turning parts of Africa into permanent disaster areas.
The experts warned that rising temperatures will also have a drastic effect on access to basic foodstuffs, with potentially dire consequences for the poor.
According to the Guardian, Frank Rijsberman, head of the world's 15 international CGIAR crop research centres, which study food insecurity, said that food production will have to rise 60 percent by 2050 just to keep pace with expected global population increase and changing demand.
A US Government report has said America's agricultural economy is set to undergo dramatic changes over the next three decades, as warmer temperatures devastate crops.
The research by 60 scientists has predicted that all crops will be affected by the temperature shift as well as livestock and fruit harvests.
