Q6. Explain the structure and functioning of estuarine ecosystems. Compare major estuaries on India’s east and west coasts. Analyse the factors contributing to their ecological stress. (15 M)
Difficulty Level: Medium

Why the question Estuarine ecosystems underpin India’s coastal productivity, fisheries and climate buffering, yet accelerating river regulation, pollution and coastal development have made their degradation a major environmental governance concern. Key demand of the question The question demands an explanation of how estuarine ecosystems are structured and function, a comparative understanding of east and west coast estuaries in India, and an analysis of the factors driving ecological stress in these systems. Structure of the Answer Introduction Briefly introduce estuaries as highly productive but fragile transition zones between riverine and marine environments with significant ecological and economic value for India. Body Explain the basic structure and ecological functioning of estuarine ecosystems as dynamic river–sea interfaces. Compare major estuaries of India’s east and west coasts with respect to geomorphology, hydrology and tidal influence. The key anthropogenic and natural factors contributing to ecological stress in Indian estuaries. Conclusion Underline the necessity of integrated river-basin management, pollution control and climate-adaptive coastal planning to ensure long-term estuarine sustainability.
