Farming in North Korea is concentrated in the flatlands of the four west coast provinces, where a longer growing season, level land, adequate rainfall, and good irrigated soil permit the most intensive cultivation of crops.
[1] The mountains contain the bulk of North Korea's forest reserves while the foothills within and between the major agricultural regions provide lands for livestock grazing and fruit tree cultivation.
Only about 17% of the total landmass, or approximately 20,000 km2, is arable, of which 14,000 km2 is well suited for cereal cultivation; the major portion of the country is rugged mountain terrain.
Between 1998 and 2008 the area of potato cultivation in North Korea quadrupled to 200,000 ha and per capita consumption increased from 16 to 60 kilograms (35 to 132 lb) per year.
[citation needed] As of 2013, the target average distribution was 573 grams of cereal equivalent per person per day, but varied according to age, occupation, and whether rations are received elsewhere (such as rice and gruel).
In January 1998, the North Korean government publicly announced that the PDS would no longer distribute rations and that families needed to somehow procure their own food supplies.
[13] Since 2005, efforts have been made to increase the availability of protein sources, primarily pigs, poultry, rabbits and fish farms and Fisheries.
In the 1990s, decreasing ability to carry out mechanized operations (including the pumping of water for irrigation), as well as lack of chemical inputs, was clearly contributing to reduced yields and increased harvesting and post-harvest losses.
[1] Incremental improvements in agricultural production have been made since the late 1990s, bringing North Korea close to self-sufficiency in staple foods by 2013.
Since 1998, there has been a gradual recovery in agriculture production, which by 2013 brought North Korea back close to self-sufficiency in staple foods.
Deprived of industrial inputs, including fertilizers, pesticides, and electricity for irrigation, agricultural output also started to decrease even before North Korea had a series of natural disasters in the mid-1990s.
This evolution, combined with a series of natural disasters including record floods in 1995, caused one of the worst economic crises in North Korea's history.
It is estimated[citation needed] that between 1992 and 1998 North Korea's economy contracted by 50% and several hundred thousand (possibly up to 3 million) people died of starvation.
[15] North Korea announced in December 1993 a 3-year transitional economic policy placing primary emphasis on agriculture, light industry, and foreign trade.
A lack of fertilizer, natural disasters, and poor storage and transportation practices have left the country more than a million tons per year short of grain self-sufficiency.
As a consequence of the government's policy of establishing economic self-sufficiency, the North Korean economy has become increasingly isolated from that of the rest of the world, and its industrial development and structure do not reflect its international competitiveness.
The food shortage was caused as a direct result of the massive flooding and a mix of political failure and poor amounts of arable land in the country.
