For example, a recent study found that yields of crops like rice and wheat are already on the decline, while harvests of sorghum, which is more drought-resistant, rose during the same period.
"This issue is especially troubling in countries with less food diversity and where people rely on one or two staple foods for their nutrition," Escribano says.
Here are the eight crops at risk of disappearing by 2050: Maize: "All major growing areaslike the US and Brazilwill be impacted by this change," Escribano says.
