Land degradation in dry and semi-arid areas is often caused by overgrazing because it mainly leads to:
- A. Increased soil fertility
- B. Loss of vegetation cover
- C. Rise in groundwater level
- D. Formation of delta plains
Answer: B. Loss of vegetation cover
Overgrazing removes grass and protective vegetation cover, exposing the soil to erosion and degradation.
Overgrazing removes grass and protective vegetation cover, exposing the soil to erosion and degradation.
Which one of the following is the correct sequence of causes leading to land degradation?
- A. Afforestation → soil conservation → improved fertility
- B. Deforestation → soil exposure → erosion
- C. Rainwater harvesting → groundwater recharge → conservation
- D. Terracing → reduced runoff → stable slopes
Answer: B. Deforestation → soil exposure → erosion
Deforestation exposes soil to wind and water erosion, which is a common pathway to land degradation.

Which of the following statements about water conservation strategies is most accurate?
- A. Rainwater harvesting is useful only in coastal regions
- B. Watershed development helps recharge groundwater and reduce runoff
- C. Drip irrigation increases water loss through seepage
- D. Canal irrigation is the only method of conserving water
Answer: B. Watershed development helps recharge groundwater and reduce runoff
Watershed development improves infiltration, groundwater recharge and soil moisture retention, making it an effective conservation strategy.
