If population growth is rapid and water sources are limited what should be the main goal of planning?

Correct answer: Water conservation and equitable distribution

Direct answer: A, water conservation and equitable distribution. Rapid population growth increases domestic, agricultural and economic demand for water, while limited sources place a ceiling on supply. Planning should therefore reduce unnecessary use, protect and recharge available sources where appropriate, improve efficiency, and allocate water fairly among people and uses. A is correct because it addresses both the limited supply and the need to share it justly. B is wrong because rejecting every possibility of developing or augmenting sources is too absolute; however, new sources alone are not enough. C is wrong because domestic use is a major planning need and cannot be ignored. D is wrong because consumption beyond availability worsens scarcity and can harm people and ecosystems. Memory cue: scarce water requires conservation, efficiency and fair allocation.
