The report came after U.N. food agencies said in a joint assessment earlier this month that about 10 million people in North Korea were facing "severe food shortages" after the country had one of the worst harvests in a decade.
In February, North Korea's ambassador to the United Nations, Kim Song, issued an unusual appeal for urgent food assistance.
North Korean officials have blamed the food shortage on bad weather and international economic sanctions that were toughened after the country conducted a series of high-profile nuclear and missile tests in recent years.
KCNA said the drought is expected to continue until the end of May. North Korea's main Rodong Sinmun newspaper reported Wednesday that officials and workers are attempting to find new water sources and mobilize pumps and irrigation equipment to minimize the damage to agriculture.
North Korea suffered a devastating famine in the mid-1990s that is estimated to have killed hundreds of thousands of people.
