Impact of Climate Change

Sea-level rise and coastal erosion: Rising sea levels in the Bay of Bengal have led to submergence of islands, saline intrusion, and habitat loss.
Increased cyclonic intensity: Frequent and intense cyclones (e.g., Amphan, Yaas) damage mangroves, embankments, and human settlements.
Salinity changes: Altered freshwater inflows due to upstream factors increase soil and water salinity, affecting mangrove species composition.
Biodiversity loss: Species such as the Royal Bengal Tiger and estuarine fauna face habitat fragmentation and prey depletion.

Impact of Anthropogenic Activities

Deforestation, shrimp aquaculture, and unplanned tourism degrade habitats.
Embankments and land-use changes disrupt natural sedimentation cycles.
Pollution and overfishing stress aquatic biodiversity.

Comprehensive Conservation Strategies

Climate-resilient ecosystem management: Large-scale mangrove afforestation with native species and restoration of degraded areas.
Integrated Coastal Zone Management (ICZM): Balance ecological protection with sustainable livelihoods through scientific zoning and monitoring.
Community-based conservation: Involve local communities through alternative livelihood schemes, eco-tourism, and awareness programmes.
Strengthening embankments and early warning systems: Nature-based solutions combined with disaster preparedness.
Transboundary cooperation: India–Bangladesh collaboration for data sharing and coordinated conservation efforts.
Policy integration: Align conservation with National Action Plan on Climate Change (NAPCC) and disaster management strategies.

In conclusion, safeguarding the Sundarbans requires a holistic approach integrating ecological restoration, climate adaptation, sustainable development, and participatory governance to ensure long-term resilience.
