Descripción
Ryanggang Province is one of the least developed regions in the Democratic People’s Republic of Korea While food security remains a major concern throughout the country, it is particularly challenging in the northern uplands of Ryanggang Province because of the low agricultural productivity and increased vulnerability to the adverse impacts of climate change Moreover, the region is facing problems associated with degenerated varieties of potato and fruit trees, degenerated livestock breeds, post harvest losses and a lack of farm equipment and machinery Low agricultural production and productivity affect the supply of food for the public distribution system, and ultimately, the nutritional status of the population According to the 2012 Nutrition Survey, chronic malnutrition ranges from 33 to 39 percent in the northern provinces of the country A major constraint to increasing the productivity of potato crops in Ryanggang Province is the availability of good quality, disease free, high yielding seed varieties When seed potatoes are multiplied conventionally using tubers, new varieties become rapidly degenerated as a result of the progressive accumulation of viruses and pathogens over several cycles of asexual reproduction Additionally, the large scale import of seed potatoes in the late 1990 s to manage the outbreak of late blight introduced new diseases into the Democratic People’s Republic of Korea, including 8 of the 22 known virus and virus like potato diseases The implications of potato disease for food security are substantial, as viral infection has the potential to reduce yields by up to 80 percent.
