Q2. “Climate variability is turning Himalayan hydrology into a hazard chain”. Explain the nature of changing precipitation extremes. Discuss their geomorphic implications and propose adaptive management measures. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: Frequent extreme rainfall and flash floods in the Himalayas have revealed the growing impact of climate variability on hydrology, making it vital to understand their geomorphic outcomes and adaptive responses for resilient mountain planning. Key Demand of the question: The question demands explaining how climate variability alters precipitation patterns in the Himalayas, analysing its geomorphic impacts like erosion, landslides, and floods, and suggesting scientific and policy-based adaptive management strategies. Structure of the Answer: Introduction: Begin with the significance of Himalayan hydrology and how climate variability is converting a water source into a hazard system. Body: Explain changing precipitation extremes — increased rainfall intensity, shifting snowline, rise in cloudbursts. Discuss geomorphic implications — slope instability, erosion, debris flow, and alteration of drainage systems. Suggest adaptive management measures — watershed-based planning, forecasting systems, hazard zoning, and eco-restoration. Conclusion: End with a forward-looking note on integrating climate science with local governance to convert hazard-prone hydrology into a resilient mountain system.
