Land use

Not to be confused with Zoning.
Global distribution of land used for agriculture

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. 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 certain land type."[4] Land use is one of the most important drivers of global environmental change.[3][5]

History

Human tribes since prehistory have segregated land into territories to control the use of land. Today, the total arable land is 10.7% of the land surface, with 1.3% being permanent cropland.[6][7]

Regulation

A land use map of Europe—major non-natural land uses include arable farmland (yellow) and pasture (light green).

Land use practices vary considerably across the world. The United Nations' Food and Agriculture Organization Water 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 the Earth was considered arable land, with 26% in pasture, 32% forests and woodland, and 1.5% urban areas. Land change modeling can 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 of

non-governmental organizations
will 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 in New York City in 1916,[10][11] and, by the 1930s, most states had adopted zoning laws. In the 1970s, concerns about the environment and historic preservation led to further regulation.

Today, federal, state, and local governments regulate growth and

statutory 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 the

National Historic Preservation Act of 1966 (today embodied in 16 U.S.C. 461 et seq.) and the National Environmental Policy Act
of 1969 (42 U.S.C. 4321 et seq.).

The

US Department of Agriculture has identified six major types of land use in the US. Acreage statistics for each type of land use in the contiguous 48 states in 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 use areas 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. Miscellaneous includes cemeteries, golf courses, marshes, deserts, and other areas of "low economic value". ** The total land area of the US is 9.1 M km2 but the total used here refers only to the contiguous 48 states, without Alaska etc.

Urban growth boundary

The urban growth boundary is one form of land-use regulation. For example, Portland, Oregon is 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 and

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 on

Land-use change, together with use of fossil fuels, are the major anthropogenic sources of carbon dioxide, a dominant greenhouse gas.[22]

Land change science refers to the interdisciplinary study of changes in climate, land use, and land 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 as remote sensing, landscape ecology, and political 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, including deforestation and urbanization.
