Land resource is fixed and cannot be increased. Land resource has been used since the ancient time. This continuous usage of land over a long period of time, without taking necessary steps to conserve and manage it has resulted in land degradation. As a matter of fact, the quality of the land has become inferior due to regular loss of fertility and irregular usage.
Human activities have also contributed towards land degradation. There are :
- Deforestation i.e., cutting down of forests.
- Over grazing.
- Mining i.e., extraction of valuable minerals from the soil.
- Mineral processing like grinding of limestone.
- Faulty methods of cultivation and over-irrigation.
These damages can be prevented with the help of these measures:
- Afforestation and proper management of grazing.
- Plantation of shelter and stabilisation of sand dunes by growing thorny bushes in windy and arid areas like the deserts of Rajasthan.
- Proper management of wasteland and control of mining activities.
- Proper discharge and disposal of industrial effluents and waste after treatment in industrial and suburban areas.
