Question

Ground water will not be depleted due to

• A. Afforestation
• B. Thermal power plants
• C. Loss of forest and decreased rainfall
• D. Cropping of high water demanding crops

Answer 1

The correct option is A Afforestation

Ground water is a valuable resource which fulfills the hydrological needs of the people. Groundwater depletion is primarily caused by sustained groundwater pumping; deforestation; overuse of fertilizers and pesticides contaminate ground water. Deforestation reduces the content of water in the soil and groundwater. Afforestation increase soil cohesion, so that erosion, flooding and landslides do not occur. Roots create macropores large conduits in the soil that increase infiltration of water and thus increase the ground water level.

Therefore, the correct answer is option A.
