What is the significance and designation status of the East Kolkata Wetlands?

  • Ramsar Status: Designated as a Ramsar Site of International Importance in 2002 for its unique sewage-fed aquaculture system.
  • State Act: Protected legislatively by the West Bengal East Kolkata Wetlands (Conservation and Management) Act enacted in 2006.
  • Ecological Role: Acts as the natural 'kidneys' of Kolkata by biologically treating urban wastewater and sewage.

Cross-Topic Patterns

  • Municipal Waste + Ramsar Wetland Conservation

    Urban landfill overload directly threatens Ramsar-designated wetlands, testing statutory protections like the 2006 State Act against municipal expansion pressures.

Dhapa waste overload + East Kolkata Wetlands Ramsar status likely to feature in a Bengal-specific environment statement question.
