Q2. The coastline of India is undergoing a silent retreat due to multiple interacting forces. Discuss how the interplay of tectonics, sediment transport, human interventions, and climate change is reshaping India’s coastal geography. (15 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the Question? India’s coastline is undergoing rapid changes due to multiple natural and human-induced factors. Understanding the interplay of tectonics, sediment transport, human activities, and climate change is crucial for sustainable coastal management. Key Demand of the Question The question requires an analysis of how tectonic shifts, sediment movement, human interventions, and climate change contribute to coastal retreat. It demands a structured examination of each factor’s role in reshaping India’s coastline with relevant examples. Structure of the Answer Introduction: Briefly introduce India’s coastline, highlighting its dynamic nature and the alarming trend of erosion and retreat with a recent study/statistic. Body: Tectonics and coastal retreat: Explain how seismic activity, land subsidence, and plate movements alter coastal morphology. Sediment transport and coastline reshaping: Discuss how disruptions in river sediment supply, mangrove degradation, and sand mining influence erosion patterns. Human interventions and coastal vulnerability: Analyze the impact of ports, urbanization, illegal mining, and CRZ violations on shoreline changes. Climate change and rising sea levels: Examine the role of sea-level rise, cyclones, changing monsoons, and coral degradation in accelerating coastal retreat. Conclusion: Suggest the need for scientific coastal management, stricter regulation, and climate adaptation strategies, citing a relevant committee recommendation or best practice.

Introduction: Briefly introduce India’s coastline, highlighting its dynamic nature and the alarming trend of erosion and retreat with a recent study/statistic.
• Tectonics and coastal retreat: Explain how seismic activity, land subsidence, and plate movements alter coastal morphology.
• Sediment transport and coastline reshaping: Discuss how disruptions in river sediment supply, mangrove degradation, and sand mining influence erosion patterns.
• Human interventions and coastal vulnerability: Analyze the impact of ports, urbanization, illegal mining, and CRZ violations on shoreline changes.
• Climate change and rising sea levels: Examine the role of sea-level rise, cyclones, changing monsoons, and coral degradation in accelerating coastal retreat.
