What are the reasons for land …

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.

Land degradation is caused by multiple forces, including extreme weather conditions particularly drought, and human activities that pollute or degrade the quality of soils and land utility negatively affecting food production, livelihoods, and the production and provision of other ecosystem goods and services.

Deforestation is taking place at a faster rate due to increasing demands of timber, fuel and forest products which results into degradation of land resources.
Overgrazing refers to excessive eating of grasses and other green plants by cattle. It results into reduced growth of vegetation, reduced diversity of plant species, excessive growth of unwanted plant species, soil erosion, and degradation of land due to cattle movement.
Following are some practises for controlling land degradation:
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 same area following a rotation system which helps in replenishment of the soil.
3. Ridge and Furrow Formation:
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.
4. Construction of Dams:
This usually checks or reduces the velocity of run off so that soil support vegetation.
5. Contour Farming:
This type of farming is usually practiced across the hill side and is useful in collecting and diverting the run off to avoid erosion.
