Land development is the alteration of landscape in any number of ways such as:

Economic aspects

In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to

Home building and containment[clarification needed

In an

urban
context, land development furthermore includes:

A

risk, and control cash flow
. This "profitable energy" means identifying and developing the best scheme for the local marketplace, whilst satisfying the local planning process.

Development analysis puts development prospects and the development process itself under the microscope, identifying where enhancements and improvements can be introduced. These improvements aim to align with best design practice, political sensitivities, and the inevitable social requirements of a project, with the overarching objective of increasing

land values and profit margins on behalf of the landowner or developer.[1]

Development analysis can add significantly to the value of land and development, and as such is a crucial tool for landowners and developers. It is an essential step in Kevin A. Lynch's 1960 book The Image of the City, and is considered to be essential to realizing the value potential of land.[2] The landowner can share in additional planning gain (significant value uplift) via an awareness of the land's development potential. This is done via a residual development appraisal or residual valuation. The residual appraisal calculates the sale value of the end product (the gross development value or GDV) and hypothetically deducts costs, including planning and construction costs, finance costs and developer's profit. The "residue", or leftover proportion, represents the land value. Therefore, in maximising the GDV (that which one could build on the land), land value is concurrently enhanced.

Land value is highly sensitive to supply and demand (for the end product), build costs, planning and affordable housing contributions, and so on. Understanding the intricacies of the development system and the effect of "value drivers" can result in massive differences in the landowner's sale value.

Conversion of landforms

Land development puts more emphasis on the expected

Conversion to building land

Conversion to building land is as a rule associated with

road building, which in itself already brings topsoil abrasion,[3] soil compaction[4] and modification of the soil's chemical composition through soil stabilization, creation of impervious surfaces and, subsequently, (polluted) surface runoff
water.

Construction activity often effectively seals off a larger part of the soil from

rainfall and the nutrient cycle, so that the soil below buildings and roads is effectively "consumed" and made infertile
.

With the notable exception of attempts at

vegetative cover of higher plants is lost to concrete and asphalt surfaces, complementary interspersed garden and park
areas notwithstanding.

Conversion to farmland

In Argentina and Bolivia, the Chaco thorn forest (A) is being felled at a rate considered among the highest in the world (B), to give way to soybean
cultivation (C)

New creation of

farmland (or 'agricultural land conversion') will rely on the conversion and development of previous forests, savannas or grassland. Recreation of farmland from wasteland, deserts or previous impervious surfaces is considerably less frequent because of the degraded or missing fertile soil in the latter. Starting from forests, land is made arable by assarting or slash-and-burn
. Agricultural development furthermore includes:

  • Hydrological measures (land levelling, drainage, irrigation, sometimes landslide and flood control)
  • fertilization
    , establishment of a productive chemical balance).
  • Road construction

Because the newly created farmland is more prone to

tree roots, such a conversion may mean irreversible crossing of an ecological threshold
.

The resulting

shelterbelts), as a rule, lack the biodiversity of the lost forest, especially when realized as monocultures.[5][6][7][8] These deforestation consequences may have lasting effects on the environment including soil stabilization and erosion control measures that may not be as effective in preserving topsoil as the previous intact vegetation
.

Restoration

Massive land conversion without proper consideration of

geological consequences may lead to disastrous results
, such as:

While deleterious effects can be particularly visible when land is developed for industrial or mining usage, agro-industrial and settlement use can also have a massive and sometimes irreversible

impact
on the affected ecosystem.

and agricultural areas.

Environmental issues

The environmental impact of land use and development is a substantial consideration for land development projects. On the local level an environmental impact report (EIR) may be necessary.[

political action committees (PACs)[further explanation needed] can influence the scope, or even cancel, a project based on concerns like the loss of an endangered species’ habitat.[citation needed
]

In most cases, the land development project will be allowed to proceed if mitigation requirements are met.[citation needed] Mitigation banking is the most prevalent example, and necessitates that the habitat will have to be replaced at a greater rate than it is removed. This increase in total area helps to establish the new ecosystem, though it will require time to reach maturity.[citation needed]

Biodiversity impacts

The extent, and type of land use directly affects

terrestrial species.[11] An example of land conversion being a chief cause of the critically endangered status of a carnivore is the reduction in habitat for the African wild dog, Lycaon pictus.[12]

Deforestation is also the reason for loss of a

Urban growth has become a problem for forests and agriculture, the expansion of structures prevents natural resources from producing in their environment.[13] In order to prevent the loss of wildlife the forests must maintain a stable climate and the land must remain unaffected by development.[citation needed] Furthermore, forests can be sustained by different forest management techniques such as reforestation and preservation. Reforestation is a reactive approach designed to replant trees that were previously logged within the forest boundary in attempts to re-stabilize this ecosystem. Preservation on the other hand is a proactive idea that promotes the concept of leaving the forest as is, without using this area for its ecosystem goods and services.[14] Both of these methods to mitigate deforestation are being used throughout the world.[citation needed
]

The

U.S. Forest service predicts that urban and developing terrain in the U.S. will expand by 41 percent in the year 2060.[15] These conditions cause displacement for the wildlife and limited resources for the environment to maintain a sustainable balance.[16]
