On what basis should sustainable use of river water be decided?

Answer and explanation

Correct answer: Human need river health and downstream requirement

The direct answer is A: human need, river health, and downstream requirement. Sustainable use means using resources today without damaging the river’s ability to support life and future users. Reasoning should include the amount of water people need, the minimum flow required for fish, plants, wetlands, and natural processes, and the water needed by communities and ecosystems downstream. These needs must be balanced with seasonal rainfall, drought risk, and pollution control. Option A includes this balanced approach and is correct. Option B, only maximum withdrawal, may remove too much water and leave the river unhealthy. Option C, only industrial demand, ignores households, farming, ecosystems, and people living downstream. Option D, only bank construction, concerns one form of infrastructure and does not decide how much water can safely be used. Sustainable planning may use monitoring, permits, conservation, recycling, and fair sharing. Memory cue: sustainable water use protects people, the river, and downstream users together.
