Question

Write a short note on the effect of water scarcity.

Answer 1

Water scarcity means insufficient availability of water for organisms and human use; it causes dehydration and disrupts normal metabolic and physiological functions in animals and plants, lowering survival, growth and reproduction. At ecosystem and human scales it leads to reduced crop yields, loss of vegetation, groundwater depletion and increased risk of desertification and resource conflict. Overall, water scarcity weakens ecosystems and human livelihoods, making efficient water management (e.g., recharge and harvesting) and conservation essential.
