Question

A large population affects water resources adversely due to _____.

• A. Building of dams
• B. Digging of canals
• C. Prayers offered for rain
• D. Higher food grain production

Answer 1

Answer: (D)

Higher food grain production

Water scarcity may be an outcome of large and growing population and consequent greater demands for water, and unequal access to it. A large population means more water not only for domestic use but also to produce more food.

Hence, to facilitate higher food-grain production, water resources are being over-exploited to expand irrigated areas and dry-season agriculture.
