A meal of a North Korean woman who lost her house in summer floods and typhoons is seen in her tent in South Hwanghae province September 30, 2011. Isolated North Korea has appealed for food aid following the disasters and years of mismanagement. In South Hwanghae province, which traditionally produces about a third of the country's total cereal supply, officials say a savage winter wiped out 65 percent of the barley, wheat and potato crops. Then summer floods and storms destroyed 80 percent of the maize harvest, according to the province's governing People's Committee, and may have an impact on the October rice harvest. Only 30 percent of a U.N. food aid target for North Korea has been met so far. The United States and South Korea, the North's two biggest donors before sanctions, have said they won't resume aid until they are satisfied the military-led communist regime will not divert the aid for its own uses and progress is made on disarmament talks.
