Question

What is meant by land degradation? Suggest any four measures to solve the problems of land degradation.

Answer 1

Hey there,
Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it has resulted in land degradation.

Following are the methods-

1. Strip farming:
It is & practice in which cultivated crops are sown in alternative strips to prevent water movement.
2. Crop Rotation:
It is one of the agricultural practice in which different crops are grown in the same area following a rotation system which helps in the replenishment of the soil.
3. Ridge and Furrow Formation:
Soil erosion is one of the factors responsible for land degradation. It can be prevented by formation of ridge and furrow during irrigation which lessens runoff.
4. Construction of Dams:
This usually checks or reduces the velocity of runoff so that soil support vegetation.
5. Contour Farming:
This type of farming is usually practiced across the hillside and is useful in collecting and diverting the runoff to avoid erosion.
