Process by which a geographic region becomes a desert. The change may result from natural changes in climate or by human activity
the gradual transformation of habitable land into desert; is usually caused by climate change or by destructive use of the land; "the dust storms in Korea are the result of rapid desertification in China
The progressive destruction or degradation of existing vegetative cover to form desert This can occur due to overgrazing, deforestation, drought, and the burning of extensive areas Once formed, deserts can only support a sparse range of vegetation Climatic effects associated with this phenomenon include increased albedo, reduced atmospheric humidity, and greater atmospheric dust (aerosol) loading
The progressive destruction or degradation of existing vegetative cover that leads to the formation of a desert This can occur due to overgrazing, deforestation, drought, or the burning of extensive areas
The degradation of terrestrial ecosystems as a result of deforestation, overgrazing, poor soil, and irrigation management
are the progressive destruction or degradation of existing vegetative cover to form desert This can occur due to overgrazing, deforestation, drought and the burning of extensive areas Once formed, desert can only support a sparse range of vegetation Climatic effects associated with this phenomenon include increased albedo, reduced atmospheric humidity and greater atmospheric dust loading, which can cause wind erosion and/or atmospheric pollution
The process of transforming and land into a barren desert Often induced by human activities or climate change
Land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities
The process through which a desert takes over a formerly non-desert area When a region begins to undergo desertification, the new conditions typically include a significantly lowered water table, a reduced supply of surface water, increased salinity in natural waters and soils, progressive destruction of native vegetation, and an accelerated rate of erosion
The process by which once-vegetated land turns into desert This can happen through natural processes such as climatic change It can also be caused or accelerated by human activities such as clear-cutting, agricultural overuse, the salinization of the soil from irrigation, or overgrazing
dry land becoming desert, either through a change in climate or through the actions of humans Intensive farming and clearing trees and other vegetation can make desertification worse
Process by which areas of desert are created by natural forests or the activities of man
Denuding and degrading a once-fertile land, initiating a desert-producing cycle that feeds on itself and causes long-term changes in soil, climate, and biota of an area
n: Conversion of rangeland, rain-fed cropland to desert-like land, with a drop in agricultural productivity of 10% or more It is usually caused by a combination of overgrazing, soil erosion, prolonged drought, and climate change
process in which climate change, population change, or population behavior transforms a semiarid region into a desert
the spread of desert conditions into areas were not previously desert This process usually occurs in arid and semi-arid environments
"Desertification means land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities" (Convention to Combat Desertification)
land degradation in arid, semi-arid, and sub-humid areas resulting from various factors, including pollution and changes in the climate
A process whereby the productivity of the land is reduced through deforestation, waterlogging and salinization, chemical degradation by nutrient leaching, range mismanagement such as overgrazing, soil erosion and aridity and semi-aridity
Land degradation in arid, semi-arid, and dry sub-humid areas resulting from various factors, including climatic variations and human activities Further, the UNCCD (The United Nations Convention to Combat Desertification) defines land degradation as a reduction or loss, in arid, semi-arid, and dry sub-humid areas, of the biological or economic productivity and complexity of rain-fed cropland, irrigated cropland, or range, pasture, forest, and woodlands resulting from land uses or from a process or combination of processes, including processes arising from human activities and habitation patterns, such as: (i) soil erosion caused by wind and/or water; (ii) deterioration of the physical, chemical and biological or economic properties of soil; and (iii) long-term loss of natural vegetation
Desertification is the process by which a piece of land becomes dry, empty, and unsuitable for growing trees or crops on. A third of Africa is under threat of desertification. the process by which useful land, especially farm land, changes into desert. Spread of a desert environment into arid or semiarid regions, caused by climatic changes, human influence, or both. Climatic factors include periods of temporary but severe drought and long-term climatic changes toward dryness. Human factors include artificial climatic alteration, as through the removal of vegetation (which can lead to unnaturally high erosion), excessive cultivation, and the exhaustion of water supplies. Desertification drains an arid or semiarid land of its life-supporting capabilities. It is characterized by a declining groundwater table, salt accumulation in topsoil and water, a decrease in surface water, increasing erosion, and the disappearance of native vegetation
The process by which lands become more desert-like, often driven by a number of complex interacting phenomena
Conversion of marginal rangeland or cropland to a more desert like land type Desertifcation can be caused by overgrazing, soil erosion, prolonged drought, or climate change
The process of becoming arid land or desert (as from land mismanagement or climate change)
The process of becoming desert (as from land management or climate change)
The man-made or natural formation of desert from usable land
the process by which once productive land is turned into a desert by processes such as overstocking or removal of protective vegetation
{i} transformation from fertile land to desert terrain (Ecology)
The progressive destruction or degradation of vegetative cover especially in arid or semiarid regions bordering existing deserts Overgrazing of rangelands, large-scale cutting of forests and woodlands, drought, and burning of extensive areas all serve to destroy or degrade the land cover The climatic impacts of this destruction include increased albedo leading to decreased precipitation, which in turn leads to less vegetative cover; increased atmospheric dust loading could lead to decreased monsoon rainfall and greater wind erosion and/or atmospheric pollution (Source: Carbon Dioxide Information Analysis Center, 1990)
