Question

what is land degradation? and tell it's causes in briefly

Answer 1

Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it, resulted in land degradation.
Some human activities such as deforestation, over grazing, mining and quarrying are the major causes of it.

I hope it will help you

Answer 2

In land degradation, land that was once rich in nutrients and able to support diverse organisms becomes compromised. Some types of degradation include salinification and acidification of soils, topsoil loss,soil compaction, and pollution of land that makes it unusable. The more degraded the soil becomes, the less it can support. This can cause degradation to speed up, as plants and animals that would normally help restore the soil are unable to survive.
Agricultural practicesare a common culprit in land degradation. Overworking the soil can damage it, sometimes permanently. A modern example of degradation can be seen in the infamous Dust Bowl of the 1930s, when large-scale topsoil loss occurred as a combination of intensive agricultural practices and drought conditions. Degradation can also be the result of overutilization of timber resources that destabilizes the ecosystem; as trees are cut down, the organisms they support are no longer able to survive.

>>>>>causes of land degradation is-
1.Deforestation-cutting down trees.
2.Mining-leaves deep scars and traces of over-burdening.
3.Over irrigation-increases th salts and alkaline deposits in the soil
4.Dumping of industrial effluents
5.Over grazing.
