Topic: Geographical features and their location- changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes.
Q2. Explain the geographical characteristics that make island ecosystems highly vulnerable to ecological disturbances. Analyse the impact of climate change and anthropogenic pressures on island ecosystems. Discuss suitable measures for ensuring ecological resilience in island regions. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question
Increasing climate change impacts, biodiversity loss and recent technology-driven conservation initiatives such as smart ecological monitoring systems in island regions have brought attention to the fragility of island ecosystems.
Key Demand of the question
The question requires explaining the geographical features that make island ecosystems ecologically fragile, analysing the combined impact of climate change and human activities on these ecosystems, and suggesting suitable resilience-oriented conservation measures.
Structure of the Answer:
Introduction
Briefly highlight islands as biodiversity hotspots with high ecological sensitivity due to isolation, limited carrying capacity and climatic dependence.
Body
- Geographical vulnerability of islands: Mention isolation, endemic biodiversity, fragile coasts, limited resources, tectonic exposure and ecological interdependence making islands highly disturbance-prone.
- Impact of climate change and anthropogenic pressures: Discuss sea-level rise, coral bleaching, cyclones, tourism pressure, invasive species, overexploitation and pollution affecting island ecosystems.
- Measures for ecological resilience: Suggest ecosystem-based conservation, climate adaptation, smart monitoring systems, sustainable tourism, community participation and international cooperation.
Conclusion
Emphasise that island ecosystems are critical ecological indicators whose protection requires integrated, technology-enabled and sustainability-oriented conservation approaches.
