Millions face starvation as world warms, say scientists ... World is unprepared for changes that will see parts of Africa turned into disaster areas, say food experts

Millions of people could become destitute in Africa and Asia as staple foods 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. Rising temperatures will also have a drastic effect on access to basic foodstuffs, with potentially dire consequences for the poor.
