“Markedly lower” rainfall is raising concern about the winter wheat and barley crops in North Korea, says the Washington Post. The winter grains supply only 5 percent of North Korea’s food but are a vital bridge, the so-called barley hump, during the spring and early summer before spring-planted crops are ready for harvest. “North Korea has a chronic food security problem,” says the Post. It says the UN Food and Agriculture Organization “forecast that the crop of early season potatoes and the winter wheat and barley crops, to be harvested starting in June, will fall considerably.” North Korean leader Kim Jung Un said last week that it is imperative to resolve the food problem.
