Farmland (farming)


Arable land (from Latin , "able to be plowed") is, according to one definition, land capable of being ploughed and used to grow crops. In Britain, it was traditionally contrasted with pasturable lands such as heaths which could be used for sheep-rearing but not farmland.

A quite different kind of definition is used by various agencies concerned with agriculture. In providing statistics on arable land, the FAO and the World Bank use the definition provided in the glossary accompanying FAOSTAT: "Arable land is the land under temporary agricultural crops (multiple-cropped areas are counted only once), temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow (less than five years). The abandoned land resulting from shifting cultivation is not included in this category. Data for ‘Arable land’ are not meant to indicate the amount of land that is potentially cultivable." A briefer definition appearing in the Eurostat glossary similarly refers to actual, rather than potential use: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation."

According to Food and Agriculture Organization of the United Nations the world's Arable land amounted to 1,407 M ha, out of a total 4,924 M ha land used for agriculture, as for year 2013.

Agricultural land that is not arable according to the FAO definition above includes:

Other non-arable land includes land unsuitable for any agricultural use.

Land that is not arable, in the sense of lacking capability or suitability for cultivation for crop production, has one or more limitations e.g. lack of sufficient fresh water for irrigation, stoniness, steepness, adverse climate, excessive wetness with impracticality of drainage, excessive salts, among others. Although such limitations may preclude cultivation, and some will in some cases preclude any agricultural use, large areas unsuitable for cultivation are agriculturally productive. For example, US NRCS statistics indicate that about 59 percent of US non-federal pasture and unforested rangeland is unsuitable for cultivation, yet such land has value for grazing of livestock. In British Columbia, Canada, 41 percent of the provincial Agricultural Land Reserve area is unsuitable for production of cultivated crops, but is suitable for uncultivated production of forage usable by grazing livestock. Similar examples can be found in many rangeland areas elsewhere.
