Japanese agriculture has been characterized as a "sick" sector because it must contend with a variety of constraints, such as the rapidly diminishing availability of arable land and falling agricultural incomes. The problem of surplus rice was further aggravated by extensive changes in the diets of many Japanese in the 1970s and 1980s.
Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
Percentage figures for arable land, permanent crops land and other lands are all taken from the CIA World Factbook [1] as well as total land area figures [2] (Note: the total area of a country is defined as the sum of total land area and total water area together.) All other figures, including total cultivated land area, are calculated on the ...
Nearly one-fourth of Japan's arable land and 22% of Japan's forests are in Hokkaido. [30] Another important plain is the Sendai Plain around the city of Sendai in northeastern Honshū. [27] Many of these plains are along the coast, and their areas have been increased by land reclamation throughout recorded history. [27]
Only 11.5% of Japan's land is suitable for cultivation. [187] Because of this lack of arable land, a system of terraces is used to farm in small areas. [188] This results in one of the world's highest levels of crop yields per unit area, with an agricultural self-sufficiency rate of about 50% as of 2018. [189]
In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land is vulnerable to land degradation and some types of un-arable land can be enriched to create useful land. Climate change and biodiversity loss, are driving pressure on arable land. [5]
Land in Bolivia was unequally distributed – 92% of the cultivable land was held by large estates – until the Bolivian national revolution in 1952. Then, the Revolutionary Nationalist Movement government abolished forced peasantry labor and established a program of expropriation and distribution of the rural property of the traditional landlords to the indigenous peasants.
Hokkaidō farms averaged 11 acres (45,000 m 2), more than four times others in Japan. Despite efforts to cultivate rice on about 60% of the arable land in the territory, climate and soils were not favorable and yields were low. Other crops included oats, potatoes, vegetables, rye and wheat as well as extensive horticulture.
