Answer 2

Rock Dam is not a method used in Arid region to check land degradation.

Rock Dam method in used in areas where floods are frequent.

Land degradation refers to the destruction of lands or desertification of land by both natural and man made factors.

Land degradation is caused by following factor:-

• Overgrazing by Animals- The unchecked grazing of large fields by animals lead to the removal of upper surface of the soil and thus land loss its quality and degraded severely

• Natural calamities- These are also the supporting factors for the land degradation. Due to this again the top layer of soil got eroded heavily which tends the land to loose its quality.

• Over exploitation of soil- Over exploitation of soil is caused by excessive farming and use of harsh pesticides and insecticides.

• Depletion of wetlands- Wetlands are marsh swampy land which helps to maintain the ecological balances in a particular region. Thus, depletion in wetland causes lack of grassland and lead to degradation of land.

Land Degradation can be checked by following methods

• Shelter belts- A line of belt of tress or shrubs that are to be planted so as to prevent soil erosion and land degradation.

• Growing of thorny bushes- The Arid areas are full of thorny bushes as a result preventing land degradation.

• Controlling Overgrazing- The grazing of Animals should be checked so as to prevent the top profile of soil to be degraded.
