India's Ramsar sites
Copy link to India's Ramsar sitesPrelims and Mains
A Ramsar listing is a promise about how a wetland will be used rather than a fence around it, so what it changes on the ground depends entirely on Indian law.
- A Ramsar site listing commits a country to the wise use of the site, and is not by itself a protection order under Indian law.
- Domestic protection comes from the Wetlands (Conservation and Management) Rules and from whatever protected area category the wetland happens to fall inside.
- Glaw Lake was designated India's 101st Ramsar site, and Arunachal Pradesh's first.
- It lies inside the Kamlang Tiger Reserve and Wildlife Sanctuary in the Eastern Himalaya, fed by perennial mountain streams.
- More than 150 tree species and 49 orchid species are recorded at the site and in its catchment.

Mining buffers around wetland reserves
Copy link to Mining buffers around wetland reservesPrelims and Mains
A national park carries a regulated belt around it; a conservation reserve carries none, and that is the gap the Supreme Court has been closing one order at a time.
- Unlike a national park or a sanctuary, a conservation reserve or community reserve carries no statutory buffer zone of its own.
- Activity that needs clearing near such an area goes to the Standing Committee of the National Board for Wildlife, the Environment Ministry, or both.
- The Supreme Court clarified orally that its 2024 order on the Asan Wetland Conservation Reserve was never about Asan alone.
- Mining within 10 km of any wetland conservation reserve or community reserve in the country now needs prior approval before it can begin.
- Asan, where the Asan meets the Yamuna in Uttarakhand, has been a Ramsar site since 2020.
What changed
Urban lakes
Copy link to Urban lakesPrelims and Mains
A city lake takes the stormwater a drain cannot, cools the air above it and recharges the water under it, so losing one costs a city more than a view.
- Urban lakes were argued to be climate infrastructure, sponge systems against heat islands and flooding, rather than sites for beautification.
- Unplanned growth, land prices, sewage and solid waste drive the loss, and eutrophication follows.
- The Comptroller and Auditor General has flagged over 500 lakes lost in Jammu and Kashmir since 1967.
- Hyderabad has lost roughly 61 per cent of its lake area since 1979.
