Which measure is useful in drought-prone regions?

Answer and explanation

Correct answer: Water harvesting

Water harvesting means collecting and storing rainwater in tanks, ponds, check dams, farm reservoirs or underground recharge structures for later use. It can supply water during dry periods, support domestic needs and farming, reduce rapid runoff and help replenish groundwater when local conditions permit. Therefore, option A is the useful drought-management measure. Wasting water increases scarcity, while excessive groundwater extraction can lower the water table and make wells unreliable. Deforestation may reduce infiltration, increase erosion and disturb the local water cycle, so it is not a sound solution. Effective drought management also combines efficient irrigation, soil-moisture conservation, suitable crops and community-based water planning.
