Land use' is also often used to refer to the distinct land use types in Zoning.Land use' is the human modification of
natural environment or
wilderness into
built environment such as fields, pastures, and settlements. The major effect of land use on
land cover since 1750 has been
deforestation of
temperate regions. More recent significant effects of land use include
urban sprawl,
soil erosion,
soil degradation,
salinization, and
desertification. Land-use change, together with use of
fossil fuels, are the major
anthropogenic sources of carbon dioxide, a dominant
greenhouse gas. It has also been defined as "the total of arrangements, activities, and inputs that people undertake in a certain land cover type" (FAO, 1997a; FAO/UNEP, 1999).
Municipal land use
Each designation, known as a parcel’s
zoning, comes with a list of approved uses that can legally operate on the zoned parcel. These are found in a government’s ordinances or
zoning regulations.
Land use and the environment
Land use and land management practices have a major impact on
natural resources including
water,
soil,
nutrients,
plants and
animals. Land use information can be used to develop solutions for natural resource management issues such as salinity and
water quality. For instance, water bodies in a region that has been deforested or having erosion will have different water quality than those in areas that are
forested.
According to a report by the
United Nations'
Food and Agriculture Organisation, land degradation has 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 to over-utilization of 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 valuable
ecosystems. Such narrow approaches should be replaced by a technique for the planning and management of land resources that is integrated and holistic and where land users are central. This will ensure the long-term quality of the land for human use, the prevention or resolution of social conflicts related to land use, and the conservation of ecosystems of high
biodiversity value.
Urban growth boundaries
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 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.
