Answer:

Which among the following is NOT the cause of Land Degradation

(a) Shelter Belt

(b) Over grazing

(c) Deforestation

(d) Mining

Answer 2

Among the following, shelter belts are not the cause of land degradation. Thus, the answer should be option A.

• Shelter belts are barriers, usually made of rows of trees. These are planted to provide shelter from the wind and to prevent soil erosion.
• The roots of the planted trees hold up the soil and prevent it from being blown away by strong winds. Thus, preventing soil erosion and in turn land degradation.
• Overgrazing is when grasslands are eaten up or destroyed by animals while grazing without giving them sufficient time to recover. It removes the plants whose roots hold up the soil and prevent soil erosion. Thus, facilitating soil erosion.
• Deforestation is the purposeful clearing of forested land. It removes the tree cover over the land and exacerbates the problem of soil erosion.
• Mining is the process of extracting useful materials from the earth. It involves cutting open the land, thus weakening the soil in the area. During rains or strong winds, the exposed soil is washed away easily.

• Thus, the answer to this question should be option A, Shelter belts.
