• The Ramsar Convention is an international treaty for the conservation and sustainable utilization of wetlands, recognizing the fundamental ecological functions of wetlands and their economic, cultural, scientific, and recreational value.
  • The Convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
  • Since then, almost 90% of UN member states, from all the world’s geographic regions, have acceded to become “Contracting Parties”.
  • The convention entered into force in India on 1 February 1982.
  • India currently has 41 sites designated as Wetlands of International Importance (Ramsar Sites), with a surface area of 1,071,861 hectare.
  • India has added two new “Ramsar Sites”, its 40th and 41st.
  • Sur Sarovar (Site no. 2440 on the List of Wetlands of International Importance), commonly known as Keetham Lake, is a human-made reservoir in the State of Uttar Pradesh in northern India.
  • Lonar Lake (Site no. 2441), on the Deccan Plateau in Maharashtra State, is an endorheic or closed basin, almost circular in shape, formed by a meteorite impact onto the basalt bedrock. The Site includes the lake as well as escarpments, which form the crater walls, and forested zones.
