There are a number of different causes/mechanisms behind the process, such as deflation (the loss of stabilizing vegetation, and of top soil); erosion; and soil-salinity-rise (via irrigation mostly).

Desertification Effects, Causes, And Examples : Top 10 List. Desertification is a process of land-degradation by which a region becomes progressively drier and drier — eventually becoming desert. Or, to put it another way — desertification is the process by which previously biologically productive land is transformed into wasteland.

Desertification is the term used to describe the erosion of topsoil and other soil properties that leads to an area becoming an environmental and economical dissent/dry land. It comes about when clay and humus and the nutrients they hold are removed and the remaining soil can’t hold nutrients.

Excessive intensity and frequency can lead to irreversible changes in ecological processes and, ultimately, to desertification. The consequences of such changes include the loss of soil organic matter, erosion, loss of biodiversity, and habitat changes for many plant and animal species (C22.3.3, C22.4.2, C22.5.1).

The lake has shrunk by 94% since the 1960s. Desertification is a type of land degradation in which relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as through climate change and through the overexploitation of soil through human activity.

In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location.

Sedentarization of nomads in marginal drylands and other limitations to their transboundary movement lead to desertification because they reduce people’s ability to adjust their economic activities in the face of stresses such as droughts (R6.2.2, C22.3.2).

Desertification is caused by a combination of factors that change over time and vary by location. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes.

Describe how the process of erosion leads to a loss of water-holding capacity and, hence, to desertification. Desertification is the term used to describe the erosion of topsoil and other soil properties that leads to an area becoming an environmental and economical dissent/dry land. This is the end of the preview.

The particulate breakdown of rock or soil into clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by its dissolving into a solvent (typically water), followed by the flow away of that solution.
