The '''East Calcutta Wetlands''', also known as the '''East Kolkata Wetlands''', are a complex of natural and human-made Wetlands lying east of the city of Calcutta (Kolkata) in India. The wetlands cover 12,500 Hectares, and include salt marshes and salt meadows, as well as sewage farms and settling ponds. The wetlands are used to treat Kolkata's sewage, and the nutrients contained in the wastewater sustain fish farms and agriculture. The East Calcutta Wetlands were designated a "wetland of international importance" under the Ramsar_Convention on August 19, 2002. ==External links== *East Calcutta Wetlands (World Wildlife Fund, India) *East Kolkata Wetlands (New Agriculturalist) Category:_Kolkata Category:_Ramsar_sites Category:_Wetlands
