According to a new study, rising temperatures and decreased rainfall in eight Southern and East African countries are likely to reduce the production of vital food crops in the region by 2050. The International Fund for Agricultural Development has issued the scientists' report, which covers Angola, Lesotho, Malawi, Mozambique, Rwanda, Uganda, Zambia, and Zimbabwe. In what IFAD describes as a "worst-case scenario," the annual maize crop in a household in Angola's Namibe province might drop by 77 percent by 2050. Beans, cassava, cowpeas, groundnuts, maize, millet, peas, pigeon peas, sesame, sorghum, sweet potato, and wheat were among the staple foods studied.
