But the report also illustrated failures, especially in parts of Africa, where in some regions more than one in three people remain hungry. Twenty-four African countries currently face food crises, the report said, twice as many as in 1990. It said “extreme weather events, natural disasters, political instability and civil strife have all impeded progress.” The report also said that hunger rates in countries suffering protracted crises were more than three times higher than elsewhere. In 2012, the report said, 366 million people were living under such conditions, and 129 million of them were hungry.
