Land use

From Wikipedia, the free encyclopedia
Global distribution of land used for agriculture

Land useinvolves the management and modification ofnatural environmentorwildernessintobuilt environmentsuch assettlementsand semi-natural habitats such asarable fields,pastures,and managedwoods.Land use by humans has a long history, first emerging more than 10,000 years ago.[1][2]It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems"[3]and as "the total of arrangements, activities, and inputs that people undertake in a certainlandtype. "[4]Land use is one of the most important drivers ofglobal environmental change.[3][5]

History

[edit]
The development of global land use over the centuries and millenia.

Human tribes sinceprehistoryhave segregated land intoterritoriesto control the use of land. Today, the totalarable landis 10.7% of the land surface, with 1.3% being permanent cropland.[6][7]

Regulation

[edit]
A land use map ofEurope—major non-natural land uses include arable farmland (yellow) and pasture (light green).

Land use practices vary considerably across the world. TheUnited Nations'Food and Agriculture OrganizationWater Development Division explains that "Land use concerns the products and/or benefits obtained from use of the land as well as the land management actions (activities) carried out by humans to produce those products and benefits."[8]As of the early 1990s, about 13% of theEarthwas considered arable land, with 26% in pasture, 32% forests and woodland, and 1.5% urban areas.Land change modelingcan be used to predict and assess future shifts in land use.

As Albert Guttenberg (1959) wrote many years ago,"'Land use' is a key term in the language ofcity planning."[9]Commonly, politicaljurisdictionswill undertakeland-use planningand regulate the use of land in an attempt to avoidland-use conflicts.Land use plans are implemented through land division and use ordinances and regulations, such aszoning regulations.Management consultingfirms andnon-governmental organizationswill frequently seek to influence these regulations before they are codified.

In colonial America, few regulations were originally put into place regarding the usage of land. As society shifted from rural to urban, public land regulation became important, especially to city governments trying to control industry, commerce, and housing within their boundaries. The first zoning ordinance was passed inNew York Cityin 1916,[10][11]and, by the 1930s, most states had adoptedzoninglaws. In the 1970s, concerns about the environment and historic preservation led to further regulation.

Today, federal, state, and local governments regulate growth anddevelopmentthroughstatutory law.The majority of controls on land, however, stem from the actions of private developers and individuals. Three typical situations bringing such private entities into the court system are: suits brought by one neighbor against another; suits brought by a public official against a neighboring landowner on behalf of the public; and suits involving individuals who share ownership of a particular parcel of land. In these situations, judicial decisions and enforcement of private land-use arrangements can reinforce public regulation, and achieve forms and levels of control that regulatory zoning cannot. There is growing concern that land use regulation is a direct cause of housing segregation in the United States today.[12]

Two major federal laws passed in the 1960s limit the use of land significantly. These are theNational Historic Preservation Act of 1966(today embodied in 16 U.S.C. 461 et seq.) and theNational Environmental Policy Actof 1969 (42 U.S.C. 4321 et seq.).

TheUS Department of Agriculturehas identified six major types of land use in the US. Acreage statistics for each type of land use in thecontiguous 48 statesin 2017 were as follows:[13]

US land use (2017)[13]
Use acreage (M) km2(M) % of total
Pasture/range 654 2.647 35
Forest 538.6 2.18 28
Cropland 391.5 1.584 21
Special use* 168.8 0.683 9
Miscellaneous* 68.9 0.279 4
Urban 69.4 0.281 4
Total** 1,891 7.653 100
  • Special useareas include national parks (29 M acres) and state parks (15 M), wildlife areas (64.4 M), highways (21 M), railroads (3M), military bases (25 M), airports (3M) and a few others.Miscellaneousincludes cemeteries, golf courses, marshes, deserts, and other areas of "low economic value". ** The total land area of the US is 9.1 M km2but the total used here refers only to the contiguous 48 states, without Alaska etc.

Urban growth boundary

[edit]

Theurban growth boundaryis one form of land-use regulation. For example,Portland, Oregonis required to have an urban growth boundary which contains at least 20,000 acres (81 km2) of vacant land. Additionally, Oregon restricts the development of farmland. The regulations are controversial, but an economic analysis concluded that farmland appreciated similarly to the other land.[14]

Land use andland managementpractices have a major impact onnatural resourcesincludingwater,soil,nutrients,plantsandanimals.[17][18]Land use information can be used to develop solutions for natural resource management issues such as salinity andwater quality.For instance, water bodies in a region that has beendeforestedor having erosion will have different water quality than those in areas that areforested.Forest gardening,a plant-based food production system, is believed to be the oldest form of land use in the world.[19]

The major effect of land use onland coversince 1750 has beendeforestationoftemperate regions.[20]More recent significant effects of land use includeurban sprawl,soil erosion,soil degradation,salinization,anddesertification.[21]Land-use change,together with use offossil fuels,are the majoranthropogenicsources of carbon dioxide, a dominantgreenhouse gas.[22]

According to a report by theUnited Nations'Food and Agriculture Organization,land degradationhas been exacerbated where there has been an absence of any land use planning, or of its orderly execution, or the existence of financial or legal incentives that have led to the wrong land use decisions, or one-sided central planning leading toover-utilizationof the land resources - for instance for immediate production at all costs. As a consequence the result has often been misery for large segments of the local population and destruction of valuablehabitatsandecosystems.

Land change sciencerefers to the interdisciplinary study of changes inclimate,land use, andland cover.[23]Land change science specifically seeks to evaluate patterns, processes, and consequences in changes in land use and cover over time. The purpose of land change science is to contribute to existing knowledge of climate change and to the development of sustainable resource management and land use policy. The field is informed by a number of related disciplines, such asremote sensing,landscape ecology,andpolitical ecology,and uses a broad range of methods to evaluate the patterns and processes that underlie land cover change. Land change science addresses land use as a coupled human-environment system to understand the impacts of interconnected environmental and social issues, includingdeforestationandurbanization.
