Q2. “Nature-based solutions are more sustainable than engineering-heavy flood control systems in monsoon-dependent regions”. Discuss. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: Asked in the context of increasing urban flooding in monsoon cities and the growing shift toward nature-based stormwater management solutions. Key Demand of the question: Discuss conventional engineering flood control methods, explain their limitations, and show why nature-based solutions offer more sustainable and hydrologically appropriate alternatives. Structure of the Answer: Introduction: Briefly define monsoon flood characteristics and highlight the need for solutions aligned with natural hydrology. Body: Explain what engineering-based flood control solutions involve (drains, pump systems, channelization). Discuss challenges faced by these solutions (cost, failure under peak load, disruption of natural drainage, recharge loss). Explain how nature-based solutions support infiltration, storage, groundwater recharge, and ecological resilience. Conclusion: Reinforce that long-term flood resilience in monsoon regions requires working with natural hydrological processes rather than against them.
