SEOUL, Aug. 21 (Yonhap) -- North Korea may see its annual crop output cut by more than 700,000 tons this year, as a severe drought this spring will hurt its summer and autumn harvest, a report in Seoul said Tuesday.

Due to the drought during May and June, the summer harvest of wheat, barley and spring potatoes declined by about 200,000 tons this year, said Kwon Tae-jin, a researcher of the Korea Rural Economic Institute, in a quarterly report on North Korea's agricultural trends.
