Question

Which of the following is not a measure for soil conservation?
(a) Strip cropping
(b) Terrace cultivation
(c) Shelter belts
(d) Overdrawing of ground water

Answer 1

(d) Overdrawing of ground water

Explanation:

• Groundwater overuse happens where the consumption of groundwater exceeds the recharge level into an aquifer, leading to a decline in the level of groundwater
• Excessive pumping can reduce the groundwater table and prevent wells from reaching groundwater .
• Land subsidence occur when support is lost beneath the ground. This is mostly caused by human activities, especially by groundwater overuse, when soils collapse, compact and drop.
• Excessive pumping can cause saltwater to flow inland and higher in coastal areas, contributing to salt water pollution of the ground water.
