What is land degradation What are its causes and how it can be controlled?

Increasing growth of population and demand for more residential areas and commercial sectors is also one of the reasons for land degradation. Soil erosion is one of the factors responsible for lad degradation. It can be prevented by formation of ridge and furrow during irrigation which lessens run off.

What are the causes of land degradation in points?

Causes include:

  • Land clearance, such as clearcutting and deforestation.
