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.〔 A narrow strip of similarly fertile land runs through the eastern seaboard Hamgyŏng provinces and Kangwŏn Province.〔 The interior provinces of Chagang and Ryanggang are too mountainous, cold, and dry to allow much farming.〔 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.〔 Major crops include rice and potatoes. 23.4% of North Korea's labor force worked in agriculture in 2012.〔(【引用サイトリンク】title=CIA World Factbook (2012 estimate) )〕 == Farming conditions == North Korea's sparse agricultural resources limit agricultural production. Climate, terrain, and soil conditions are not particularly favorable for farming, with a relatively short cropping season. Only about 17% of the total landmass, or approximately , is arable, of which is well suited for cereal cultivation; the major portion of the country is rugged mountain terrain.〔 The weather varies markedly according to elevation, and lack of precipitation, along with infertile soil, makes land at elevations higher than 400 meters unsuitable for purposes other than grazing. Precipitation is geographically and seasonally irregular, and in most parts of the country as much as half the annual rainfall occurs in the three summer months. This pattern favors the cultivation of paddy rice in warmer regions that are outfitted with irrigation and flood control networks. Rice yields are 5.3 tonnes per hectare, close to international norms.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agriculture in North Korea」の詳細全文を読む スポンサード リンク
