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

History

Land development has a history dating to Neolithic times around 8,000 BC. From the dawn of civilization, the process of land development has elaborated the progress of improvements on a piece of land based on codes and regulations, particularly housing complexes.

Economic aspects

In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to investment making land more usable by humans. For accounting purposes it refers to any variety of projects that increase the value of the process . Most are depreciable, but some land improvements are not able to be depreciated because a useful life cannot be determined. Home building and containment[ clarification needed ] are two of the most common and the oldest types of development.

In an urban context, land development furthermore includes:

A landowner or developer of a project of any size, will often want to maximise profits, minimise 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 economic development as a result of the process; "land conversion" tries to focus on the general physical and biological aspects of the land use change. "Land improvement" in the economic sense can often lead to land degradation from the ecological perspective. Land development and the change in land value does not usually take into account changes in the ecology of the developed area. While conversion of (rural) land with a vegetation carpet to building land may result in a rise in economic growth and rising land prices, the irreversibility of lost flora and fauna because of habitat destruction, the loss of ecosystem services and resulting decline in environmental value is only considered a priori in environmental full-cost accounting.

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.

Building construction

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 rooftop gardening and hanging gardens in green buildings (possibly as constituents of green urbanism), vegetative cover of higher plants is lost to concrete and asphalt surfaces, complementary interspersed garden and park areas notwithstanding.[ citation needed ]

Conversion to farmland

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:

Because the newly created farmland is more prone to erosion than soil stabilized by tree roots, such a conversion may mean irreversible crossing of an ecological threshold.

The resulting deforestation is also not easily compensated for by reforestation or afforestation. This is because plantations of other trees as a means for water conservation and protection against wind erosion (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 ecological and 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. [9]

Examples of land restoration/land rehabilitation counted as land development in the strict sense are still rare. However, renaturation, reforestation, stream restoration may all contribute to a healthier environment and quality of life, especially in densely populated regions. The same is true for planned vegetation like parks and gardens, but restoration plays a particular role, because it reverses previous conversions to built 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.[ definition needed ] In the United States, federally funded projects typically require preparation of an environmental impact statement (EIS). The concerns of private citizens or 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 wildlife habitat and thereby impacts local and global biodiversity. [10] Human alteration of landscapes from natural vegetation (e.g. wilderness) to any other use can result in habitat loss, degradation, and fragmentation, all of which can have devastating effects on biodiversity. [11] Land conversion is the single greatest cause of extinction of terrestrial species. [12] 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. [13]

Deforestation is also the reason for loss of a natural habitat, with large numbers of trees being cut down for residential and commercial use. Urban growth has become a problem for forests and agriculture, the expansion of structures prevents natural resources from producing in their environment. [14] 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. [15] 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. [16] These conditions cause displacement for the wildlife and limited resources for the environment to maintain a sustainable balance. [17]

Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities.

<span class="mw-page-title-main">Resource depletion</span> Depletion of natural organic and inorganic resources

Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources. The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource. The more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, including but not limited to: mining for fossil fuels and minerals, deforestation, pollution or contamination of resources, wetland and ecosystem degradation, soil erosion, overconsumption, aquifer depletion, and the excessive or unnecessary use of resources. Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and the consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

<span class="mw-page-title-main">Environmental degradation</span> Any change or disturbance to the environment perceived to be deleterious or undesirable

Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. The environmental degradation process amplifies the impact of environmental issues which leave lasting impacts on the environment.

<span class="mw-page-title-main">Forestation</span>

Forestation is a vital ecological process where forests are established and grown through afforestation and reforestation efforts. Afforestation involves planting trees on previously non-forested lands, while reforestation focuses on replanting trees in areas that were once deforested. This process plays an important role in restoring degraded forests, enhancing ecosystems, promoting carbon sequestration, and biodiversity conservation.

<span class="mw-page-title-main">Habitat destruction</span> Process by which a natural habitat becomes incapable of supporting its native species

Habitat destruction occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.

The Mesoamerican Biological Corridor (MBC) is a region that consists of Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, and some southern states of Mexico. The area acts as a natural land bridge from South America to North America, which is important for species who use the bridge in migration. Due to the extensive unique habitat types, Mesoamerica contains somewhere between 7 and 10% of the world’s known species.

Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture, forest protection, and forest regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values. Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, planting and replanting of different species, building and maintenance of roads and pathways through forests, and preventing fire.

<span class="mw-page-title-main">Forest protection</span> Branch of forestry

Forest protection is a branch of forestry which is concerned with the preservation or improvement of a forest and prevention and control of damage to forest by natural or man made causes like forest fires, plant pests, and adverse climatic conditions.

<span class="mw-page-title-main">Wetland conservation</span> Conservation of wet areas

Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species. Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide. More than three billion people, around half the world's population, obtain their basic water needs from inland freshwater wetlands. They provide essential habitats for fish and various wildlife species, playing a vital role in purifying polluted waters and mitigating the damaging effects of floods and storms. Furthermore, they offer a diverse range of recreational activities, including fishing, hunting, photography, and wildlife observation.

Akure Forest Reserve is a protected area in southwest Nigeria, covering 66 km2 (25 sq mi). The Akure Forest Reserve, established in 1948 and spanning approximately 32 hectares. It was created with the primary aim of safeguarding the genetic diversity of the forest ecosystem. About 11.73% is estimated to be cleared for cocoa farming and other food crops. Aponmu and Owena Yoruba speaking communities owned the forest, though, there are also minor settlements surrounding the forest. They include Ipogun, Kajola/ Aponmu, Kajola, Ago Petesi, Akika Camp, Owena Town, Ibutitan/Ilaro Camp, Elemo Igbara Oke Camp and Owena Water new Dam.

<span class="mw-page-title-main">Forest restoration</span>

Forest restoration is defined as "actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest", i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.

<span class="mw-page-title-main">Forest conservation in the United States</span>

Forest conservation is the practice of planning and maintaining forested areas for the benefit and sustainability of future generations. Forest conservation involves the upkeep of the natural resources within a forest that are beneficial for both humans and the ecosystem. Forests provide wildlife with a suitable habitat for living which allows the ecosystem to be biodiverse and benefit other natural processes. Forests also filter groundwater and prevent runoff keeping water safe for human consumption. There are many types of forests to consider and various techniques to preserve them. Of the types of forests in the United States, they each face specific threats. But, there are various techniques to implement that will protect and preserve them.

<span class="mw-page-title-main">Niger Delta swamp forests</span>

The Niger Delta swamp forests is a tropical moist forest ecoregion in southern Nigeria. It consists of freshwater swamp forests in the Niger Delta of the Niger River. This swamp forest is the second largest in Africa after the Congolian swamp forests. Although there are large cities just outside the ecoregion, the area has been relatively isolated by the difficulty of building roads across the swamps, although this is changing with development of oil and logging industries. Scientific surveys have only begun in recent years, and new species were being identified into the 1990s. Crude oil exploration and pollution has been a threat to forests in the Niger Delta region.

In Nigeria, firewood is a traditional source of energy for domestic and commercial use. Fuel wood is derived from cutting and burning wood materials such as logs and twigs. It has long been prevalent among rural and sometimes urban dwellers.

<span class="mw-page-title-main">Reforestation in Nigeria</span>

Reforestation in Nigeria employs both natural and artificial methods. Reforestation involves the deliberate planting of trees and restoring forested areas that have been depleted or destroyed. It involves a planned restocking of the forest to ensure sustainable supply of timber and other forest products. Reforestation, in essence, involves replenishing forests to guarantee a consistent and sustainable supply of timber and various other forest resources. This objective can be accomplished through either natural regeneration techniques or artificial regeneration methods. Both of these approaches have been utilized in the reforestation efforts within Nigeria's forests. At the initiation of the reforestation program in Nigeria, the natural regeneration approach was chosen for two primary reasons. Firstly, it aimed to preserve the rainforest in its original state by allowing it to regenerate naturally from the existing seed bank in the soil. Secondly, and of significant importance, this method was selected due to budgetary constraints, as there were insufficient funds available to establish plantations through direct means.

<span class="mw-page-title-main">Fruit production and deforestation</span>

Fruit production is a major driver of deforestation around the world. In tropical countries, forests are often cleared to plant fruit trees, such as bananas, pineapples, and mangos. This deforestation is having a number of negative environmental impacts, including biodiversity loss, ecosystem disruption, and land degradation.
