Prohibited Content 3. The continued loss of arable land will jeopardize our ability to feed the world population. Soil salinization is the concentration of salts in the surface or near surface of soils. Offshore fishing grounds, some of the only areas on earth from where fish catches are increasing, are also open to plundering, often by industrial foreign fleets. Land degradation therefore has potentially impacts on lakes and reservoirs that are designed to alleviate flooding provide irrigation and generate Hydro-Power. However, investors and developers have started to persuade governments of the region of the financial benefits of such practices, which, if not sensibly developed, can adversely affect not only the forests, but also the many fisheries and people who depend on the productivity of the habitat. Causes include: Land clearance, such as clearcutting and deforestation; Agricultural depletion of …

If climate change continues unabated, the potential increase in the frequency and intensity of droughts would reinforce the variability of dry-land ecosystems. Destructive fishing practices This is called rill erosion. Most of the soil eroded from the land together with the chemical fertilizers utilized in agricultural fields is discharged into waterways. Most agricultural practices involving the use of fertilizers and pesticides entail misuse or excessive application, thereby contributing to the killing of soil’s beneficial bacteria and other micro-organisms that help in soil formation. Excess use of alkaline fertilizers like sodium nitrate, basic slag, etc. The value of the land for humans, animals, plant/vegetation and organisms is lessened as a result of land degradation.

Soil degradation causes, effects, preventive methods. Some land degradation such as the effects of water and wind erosion may be largely irreversible – at least over the span of thousands of years (top soil can take millennia to form again naturally). Acidification, compaction and salinization are some other causes of agricultural land degradation. 1. The sudden movement of the soil and the weathered rock material down the slope due to the force of gravity is called a landslide. In this article we also discuss below topics; Soil degradation examples contain a decline in soil fertility, adverse changes in alkalinity, acidity or salinity, extreme flooding, use of toxic soil pollutants, erosion, and deterioration of the soil’s structural condition. Investment and further research and testing into sustainable farming and land restoration is also important], [subsidies, rewards and insurances for farmers who implement soil restoration practices may also be a priority], New farming practices like terraces and temporary “cover” crops have helped lower soil erosion by more than 40 percent over the past two decades. Rainfall, surface runoff, floods, wind erosion, tillage, and mass movements result in the loss of fertile top spoil thus declining soil quality.

When drylands are irrigated, the water evaporates quickly, leaving behind previously dissolved salts. Plagiarism Prevention 4. Over the last few decades destructive fishing methods, such as the use of dynamite and small-meshed nets, have destroyed seagrass beds and coral reefs. Extraction of groundwater or soil vapor with an active electromechanical system, with subsequent stripping of the contaminants from the extract. Millions of people in Africa and Asia raise animals on pastures and rangelands that have low carrying capacity because of poor quality or unreliable rainfall Pastoralists and their rangelands are threatened by overgrazing. from one location to another where land/soil becomes contaminated or degraded. Your email address will not be published. In India, landslides are common in the mountainous regions of the north and north-eastern parts. The removal of grass and shrubs leaves the soil bare and susceptible to wind and water erosion. In Mozambique alone the industrial and semi-industrial fishing fleet exceeds 150 vessels, earning the economy over US$ 100 million per year, mostly through the export of shrimps.
