Q2. Examine the causes of increasing monsoon rainfall in the Western Ghats. Discuss its implications for geomorphological processes in the region. (10 M)
Difficulty Level: Medium
Reference: TH
Why the question: A recent study by researchers at the Central University of Kerala (CUK) has revealed a significant increase in monsoon rainfall in the Western Ghats over the past 800 years Key Demand of the question: The question demands an examination of climatic and environmental drivers behind rising monsoon rainfall in the Western Ghats, and a discussion of how this increase impacts geomorphological processes like erosion, landslides, and sedimentation. Structure of the Answer: Introduction: Briefly refer to the recent multi-disciplinary study showing an 800-year monsoon trend and rising intensity, framing it in the context of long-term climate variability. Body: Causes of increasing monsoon rainfall: Point to oceanic warming, atmospheric changes, and land-use modifications influencing monsoonal intensity. Implications for geomorphological processes: Highlight effects like increased landslides, accelerated erosion, river course instability, and sedimentation in the region. Conclusion: Call for integrating climate projections with geomorphological risk zoning to ensure sustainable development in the Western Ghats.
