Causes of land degradation and how to prevent from this
  • 1 answers

Yogita Ingle 7 years, 11 months ago

Land degradation: When land becomes barren, infertile for cultivation, it is called land degradation.
Causes:

  • Overgrazing by animals
  • Deforestation
  • Over mining and quarrying
  • Over irrigation resulting in water logging leading to salinity and alkalinity.
  • Mineral processing, like grinding of limestone for cement industry and calcite and soapstone for ceramic industries, generates heavy amount of dust and pollutes atmosphere. It later settles down on land and reduces infiltration of water into the soil besides degrading land and surface water.
  • Discharge of industrial effluents into water bodies and on land.

Prevents:

  • Terrace farming
  • Construction of dams
  • Afforestation
  • Preparation of shelter belts
  • Control on overgrazing by animals
  • Stabilization of sand dunes by growing thorny bushes.
