Question

This question was previously asked in

SSC CGL 2021 Tier-I (Held On : 21 April 2022 Shift 2)

Construction of retention wall to stop land from slipping
Hazard mapping to locate areas prone to landslides
Reduction in the vegetation cover to arrest landslide
The surface drainage control works to control the movement of landslide along with rain water and spring flows.

Answer 1

The correct answer is Reduction in the vegetation cover to arrest landslides.

Key Points

Decreasing vegetation cover to arrest landslides is NOT correct among the mechanisms of landslides mitigation.
Landslides Mitigation Mechanisms:
- Hazard mapping to identify areas prone to landslides.
- Construction of retention walls to stop land slippage.
- Increasing vegetation cover to arrest landslides.
- Ensuring surface drainage control works to restrict the movement of landslides.
- Formation of any header niche and perforation.

Additional Information

A landslide:
- It is defined as the movement of a mass of rock, debris, or earth down a slope.
- Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.
