As devastating floods ravaged the country in 1995, arable land, harvests, grain reserves, and social and economic infrastructure were destroyed. The United Nations Department of Humanitarian Affairs reported that "between 30 July and 18 August 1995, torrential rains caused devastating floods in the Democratic People's Republic of Korea (DPRK). In one area, in Pyongsan county in North Hwanghae province, 877 mm of rain were recorded to have fallen in just seven hours, an intensity of precipitation unheard of in this area... water flow in the engorged Amnoc River, which runs along the Korea/China border, was estimated at 4.8 billion tons over a 72 hour period.
