Agricultural land is typically land ''devoted to'' agriculture,〔''Oxford English Dictionary'', "agricultural, ''adj.''" Oxford University Press (Oxford), 2012.〕 the systematic and controlled use of other forms of lifeparticularly the rearing of livestock and production of cropsto produce food for humans.〔''Oxford English Dictionary'', "agriculture, ''n.''" Oxford University Press (Oxford), 2012.〕〔See also, e.g., Provincial Agricultural Land Commission. "(What is Agricultural Land? )" The Province of British Columbia. Accessed 1 Aug 2014.〕 It is thus generally synonymous with farmland or cropland. The United Nations Food and Agriculture Organization and others following its definitions, however, also use agricultural land or as a term of art, where it means the collection of:〔FAO. ''(FAOSTAT Glossary )'': "Agricultural area".〕〔OECD. (''Glossary of Statistical Terms'': "Agricultural land". )〕 * "arable land": here, redefined to describe land producing crops requiring annual replanting or fallowland or pasture used for such crops within any five-year period * "permanent cropland": land producing crops which do not require annual replanting * permanent pastures: natural or artificial grasslands and shrublands able to be used for grazing livestock This sense of "agricultural land" thus includes a great deal of land not actively or even presently devoted to agricultural use. The land actually under annually-replanted crops in any given year is instead said to constitute or "Permanent cropland" includes forested plantations used to harvest coffee, rubber, or fruit but not tree farms or proper forests used for wood or timber. Land able to be used for farming (traditionally called arable land but here described as "arable land" and "permanent cropland" together) is called . Farmland, meanwhile, is used variously in reference to all agricultural land, to all cultivable land, or just to the newly restricted sense of "arable land". Depending upon its use of artificial irrigation, the FAO's "agricultural land" may be divided into irrigated and non-irrigated land. In the context of zoning, agricultural land or agriculturally-zoned land refers to plots that are ''permitted'' to be used for agricultural activities, without regard to its present use or even suitability. In some areas, agricultural land is protected so that it can be farmed without any threat of development. The Agricultural Land Reserve in British Columbia, for instance, requires approval from its Agricultural Land Commission before its lands can be removed or subdivided.〔Provincial Agricultural Land Commission. (Official website ). Accessed 1 Aug 2014.〕 ==Area== Under the FAO's definitions above, agricultural land covers 33% of the world's land area, with the FAO's arable land representing less than ⅓ of that or about 9.3% of the world's land area. The specific agricultural areas around the globe as of 2009 were:〔(FAOSTAT data on land use )〕〔(''WDI –World Development Indicators'' online database ), retrieved on July 18, 2008 (may require subscription for access; (print edition ) from the World Bank).〕 * Arable land: * Permanent crops: * Permanent pastures: Source: Helgi Library,〔(helgilibrary.com: "Agricultural Land Area" 2014-02-12 )〕 World Bank, FAOSTAT 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「agricultural land」の詳細全文を読む スポンサード リンク
