Ramsar Wetlands of India GK Questions & Answers

Reviewed by the Master10 Editorial Board for accuracy, clarity and competitive-exam relevance.Editorial Policy
The Convention on Wetlands of International Importance, signed on 2 February 1971 in Ramsar, Iran, provides the intergovernmental framework for national action and multilateral cooperation. India acceded to the convention on 1 February 1982, committing to designate and preserve wetlands of international importance. Qualification requires satisfying at least one of nine criteria divided into two groups: Group A covers representative, rare, or unique natural wetland types, while Group B prioritizes biodiversity conservation, particularly vulnerable species, ecological communities, waterbirds, and fish. Specifically, Criterion 5 mandates regular support for 20,000 or more waterbirds, whereas Criterion 6 requires sustaining one percent of the individuals in a biogeographical population of a waterbird species or subspecies.

Wetlands undergoing acute ecological deterioration are placed on the Montreux Record, a specialized register established during COP 4 at Montreux, Switzerland, in 1990. The record highlights Ramsar sites where changes in ecological character have occurred, are occurring, or are likely to occur from technological developments, pollution, or human interference. India has had three sites placed on this register: Keoladeo National Park in Rajasthan (inscribed in 1990 due to water scarcity and grazing pressures), Loktak Lake in Manipur (inscribed in 1993 following habitat disruption by the Ithai Barrage), and Chilika Lake in Odisha (inscribed in 1993 owing to siltation). Following targeted desiltation and mouth restoration by the Chilika Development Authority, Chilika was delisted in 2002, becoming Asia's first restored site.

Geographically, India occupies a focal crossroads along the Central Asian Flyway (CAF), which covers thirty nations and supports over 182 migratory waterbird species traversing between Arctic breeding grounds and South Asian wintering wetlands. The Ministry of Environment coordinates the National Action Plan for Conservation of Migratory Birds along this corridor, complemented by the Amrit Dharohar initiative promoting community stewardship around Ramsar locations. In UPSC CSE (GS Paper III) and SSC CGL examinations, key testing areas include Ramsar qualification criteria, statutory triggers for Montreux Record listings, restoration techniques applied at Chilika Lake, geographic coordinates of newly notified Indian wetlands, and intergovernmental flyway treaties.

Educator's Insight
Wetlands are nature's water filters and flood shock-absorbers, providing critical breeding grounds for migratory waterfowl. The Ramsar Convention, signed in Iran in 1971, provides an international framework to protect these fragile aquatic habitats. India joined in 1982 and has expanded its recognized wetlands nationwide, from the massive mangrove forests of the Sundarbans to tiny sub-alpine lakes like Renuka. Severely threatened sites facing ecological degradation are placed on the specialized Montreux Record for intensive conservation action.
Environment questions in UPSC prelims and State PSC exams frequently focus on Ramsar site lists and Montreux Record status. Watch out for statement traps: only two Indian wetlands are currently listed on the Montreux Record—Keoladeo National Park in Rajasthan and Loktak Lake in Manipur. Remember that Chilika Lake was removed from the Montreux Record in 2002 after successful mouth restoration. Also keep in mind for MCQs that the Sundarbans is India's largest Ramsar wetland, while Renuka is the smallest.
