At a time when extreme air pollution dominates the news, there’s a glimmer of environmental hope: Delhi could soon have a Ramsar site. The government is working to notify the 5.16-hectare Neeli Jheel, located in the Asola Bhatti Wildlife Sanctuary, as Delhi’s first Ramsar site. The move was announced by Delhi Environment Minister Manjinder Singh Sirsa on World Wetlands Day, February 2, 2026.
Calling wetlands vital to both life and culture, Sirsa said that conserving water bodies is not only an environmental responsibility but also closely tied to safeguarding traditions and ensuring the security of future generations. He noted that Delhi once had more than 1,000 water bodies, many of which were lost to encroachment and neglect. The Delhi government, he added, has resolved to revive all water bodies and aims to restore as many as possible by the end of 2027.
Neeli Jheel, also called Bharadwaj Lake, is a 2-km-long, 100-foot-deep man-made lake located within Delhi’s Asola Bhatti Wildlife Sanctuary. Created in a former mining pit, the pristine blue-water lake is rich in biodiversity and is currently being developed as an ecotourism destination.
A Ramsar site is a wetland designated as being of “international importance” under the Ramsar Convention of 1971. These sites are recognised for their high biodiversity value. While the status does not in itself confer legal protection, it signifies a commitment to preserving the ecological character of the site. They support unique flora and fauna and provide vital ecosystem services such as water purification and flood control.
Designating a place as a Ramsar site leads to the conservation and wise use of wetlands, especially those that serve as critical habitats for waterfowl. These are all distinctive ecosystems and include lakes, marshes, and mangroves. They play an essential role in maintaining ecological balance and regulating the climate.
As of January 2026, India has 98 Ramsar sites, reflecting the country’s commitment to wetland conservation. The most recent additions include the Patna Bird Sanctuary and Chhari-Dhand, bringing the total wetland area under Ramsar designation to over 13.6 lakh hectares.
Tamil Nadu has the highest number of sites at 20, while the Sundarban Wetland in West Bengal is the largest, and Renuka Wetland in Himachal Pradesh the smallest. India’s first Ramsar sites—Chilika Lake in Odisha and Keoladeo National Park in Rajasthan—were designated in 1981, and the country currently has the highest number of Ramsar sites in Asia.
