West Bengal Initiates Sundarbans Mangrove Restoration Drive

Source:The Hindu ↗

Why It Matters

Crucial for WBCS aspirants to track regional environmental policy updates, coastal ecosystem management, and geographical conservation efforts in the Sundarbans.

Summary

The West Bengal government has announced a comprehensive drive to restore mangrove forests in the Sundarbans that have been degraded or lost due to anthropogenic encroachments. The initiative emphasizes environmental protection, climate resilience, and preserving the ecological integrity of the world's largest mangrove delta.

Key Points

  • The West Bengal government has pledged to restore mangroves lost to encroachments and illegal clearings in the Sundarbans region.
  • Sundarbans ecosystem is vital for ecological security, acting as a natural coastal buffer against severe cyclones, storm surges, and coastal erosion.
  • Encroachments in the deltaic region threaten the unique biodiversity, including the habitat of the Royal Bengal Tiger and local livelihoods.

Important Terms

Sundarbans

The world's largest contiguous mangrove delta, spread across India and Bangladesh, known for its rich biodiversity and critical role as a natural coastal buffer against severe tropical cyclones.

Bheries

Traditional shallow brackish-water fish and prawn ponds constructed in coastal wetland areas, often blamed for illegal mangrove deforestation in the Sundarbans.

Mangrove Forests

Salt-tolerant evergreen halophytic forests growing in intertidal coastal zones that protect shorelines from erosion, absorb carbon, and buffer storm surges.

Geography of West Bengal

What are the key geographical features and conservation designations of the Sundarbans?

  • Riverine Delta: Largest Delta: Formed by the deltaic confluence of the Ganges, Brahmaputra, and Meghna rivers, spanning India and Bangladesh.
  • Global Recognition: UNESCO Status: Designated as a UNESCO World Heritage Site in 1987 and a Ramsar Wetland of International Importance.
  • Biodiversity Hub: Faunal Pride: Home to the endangered Royal Bengal Tiger and unique estuarine biodiversity adapted to tidal regimes.
Environmental Conservation West Bengal

What percentage of India's mangrove cover does West Bengal hold, and what is their ecological role?

  • Highest Share: Dominant Share: West Bengal accounts for roughly 42.45% of India's total mangrove cover, the highest in the country.
  • Coastal Buffer: Natural Shield: Act as shock absorbers against severe tropical cyclones, storm surges, and coastal erosion in the Bay of Bengal.
  • Ecological Value: Carbon Sinks: High rates of carbon sequestration ('blue carbon') and vital nursery grounds for marine fisheries.

Cross-Topic Patterns

  • Mangrove Conservation Meets Disaster Management

    Sundarbans mangrove restoration directly links climate resilience initiatives with coastal disaster mitigation strategies against cyclones like Amphan and Yaas.

  • Aquaculture Encroachments vs. Coastal Regulation Zones

    Unauthorized aquaculture bheries in the Sundarbans connect localized land-use violations with broader wetland conservation and coastal regulation zone (CRZ) rules.

Expect matching or multi-statement questions on India's mangrove cover distribution (WB share ~42.45%) and Sundarbans' ecological designations.
