Translations for land degradation Land degradation. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.

ESS Soil Outline the process and consequences of soil degradation. Human activities such as overgrazing, deforestation, unsustainable agriculture and irrigation cause processes of degradation. These include soil erosion (loss of soil to wind and water), intoxication and salinization (increase in salt concentration).

- This paper focuses on terrestrial degradation-which may be defined as the loss of utility or potential utility or its reduction, or the loss or change of features or organisms that cannot be replaced (Barrow, 1991) - and on deforestation and desertification in particular.

Land degradation Serious land degradation in Nauru after the depletion of the phosphate cover through mining. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.igh population density is not always related to land degradation. Rather, it is the practices of the human population that can cause a landscape to become degraded. Populations can be a benefit to the land and make it more productive than it is in its natural state.

What is Environmental Degradation? It occurs when earth’s natural resources are depleted and environment is compromised in the form of extinction of species, pollution in air, water and soil, and rapid growth in population. Environmental degradation is one of the largest threats that are being looked at in the world today.

What is Soil Erosion? Soil erosion is one form of soil degradation. The erosion of soil is a naturally occurring process on all land. The agents of soil erosion are water and wind, each contributing a significant amount of soil loss each year. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing serious loss of topsoil.

Effects of global warming on human health Definition.  1 Desertification is the degradation of land in arid, semi-arid, and dry sub-humid areas. It is caused primarily by human activities and climatic variations. 2  In different areas of the world, the causes and effects of desertification may be different. For example, this short report by the BBC in the 1999 shows how different causes of desertification have combined together in China.

Wat is the difference between forest degradation and deforestation? Submit. · just now. Report Abuse. simply put, degradation means the forest is still there, but in bad health--loss of habitats, loss of trees, inability to replace trees naturally, erosion, lack of plant and animal diversity. deforestation means the forest no longer exists at all, all the trees are gone.

Forest degradation For the purpose of having a harmonized set of forest and forest change definitions, that also is measurable with conventional techniques, forest degradation is assumed to be indicated by the reduction of canopy cover and/or stocking of the forest through logging, fire, windfelling or other events, provided that the canopy cover stays above 10% (cf. ...

9 what are some problems with the sweeping claims 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.

- Soil erosion results in the loss of soil fertility and makes the land barren. There are more than 25 million hectares of barren lands in the world now. Soil erosion also leads to desertification. Desertification refers to increase of desert areas.

Desertification Desertification is the persistent degradation of dryland ecosystems by variations in climate and human activities. Home to a third of the human population in 2000, drylands occupy nearly half of Earth’s land area.. Desertification diminishes biological diversity, a diversity which contributes to many of the services provided to humans by dryland ecosystems. Vegetation and its diversity are key for soil conservation and for the regulation of surface water and local climate.

Desertification 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.

- Nevertheless, most globally established definitions allude to the basic notion of a human-induced, long-term, negative change in the forest’s structure, function and capacity to provide goods and services in general. Degradation has thus the clearly negative connotation of a long-term impairment of a forest.

What is erosion? Erosion is the wearing away of the surface of the earth! Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations.The wearing away of land or soil by the action of wind, water, or ice.In hydrologic terms, wearing away of the lands by running water, glaciers,winds, and waves, can be subdivided into three process: Corrasion, Corrosion, and Transportation.he wearing away of land or soil by the action of wind, water, or ice.
