Ramsar Sites in India: Essential Wetland Conservation Facts for UPSC

Quick Answer: Ramsar Sites are wetlands of international importance designated under the Ramsar Convention (1971, Ramsar, Iran), an inter-governmental treaty that came into force in 1975. India designated its first two sites — Chilika Lake and Keoladeo National Park — in 1981, and the list has since grown past 85 sites, making India the largest in Asia and third-largest in the world. Tamil Nadu has the highest number of Ramsar Sites among Indian states.

The Ramsar Convention: Origin, Objectives, and Key Facts

The Convention on Wetlands was signed on 2 February 1971 in the town of Ramsar, Iran, and entered into force in 1975. It is the oldest modern global inter-governmental environmental treaty, focused on the conservation and “wise use” of wetlands. Key MCQ facts:

  • Signed: 1971, Ramsar, Iran; in force: 21 December 1975.
  • Depository: UNESCO is the depository of the treaty.
  • Not a UN treaty: It is an inter-governmental treaty in its own right, though it works closely with UNESCO, UNEP and IUCN.
  • Secretariat: Located in Gland, Switzerland, hosted by IUCN.
  • India joined: India became a party on 1 February 1982.

Authoritative references include the official convention website (ramsar.org) and IUCN (iucn.org).

How a Wetland Is Designated as a Ramsar Site

A wetland qualifies as a Ramsar Site if it meets at least one of nine criteria grouped under representativeness, rarity and biodiversity. The most frequently tested examples:

  • Criterion 5: It regularly supports 20,000 or more waterbirds.
  • Criterion 6: It regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.
  • Other criteria cover rare or unique wetland types, endangered species, fish diversity and internationally important waterbird flyway sites.

The nomination is made only by the national government of a member country — there is no external inspection that forces inclusion. Importantly for Prelims, designation imposes no binding legal obligations; it relies on the moral commitment of parties to promote “wise use” of the listed wetland.

India’s Ramsar Journey: From Chilika (1981) to 85+ Sites

India designated its first two Ramsar Sites in 1981: Chilika Lake (Odisha) and Keoladeo National Park (Rajasthan). The list grew slowly for decades, then expanded rapidly after 2020, crossing 75 sites in 2023–24 and reaching 85+ sites with subsequent additions announced around World Wetlands Day (2 February) celebrations. This expansion made India the country with the largest number of Ramsar Sites in Asia and the third-largest in the world, after the United Kingdom and Mexico. Because new sites are added periodically, always verify the latest count from the official Ramsar list or PIB before your exam.

State-Wise Distribution of Ramsar Sites: MCQ Traps to Remember

  • Tamil Nadu has the highest number of Ramsar Sites (including Point Calimere, Pallikaranai, Karikili, Pichavaram, Vembanur, and the Gulf of Mannar area sites).
  • UP follows with sites such as Upper Ganga, Sambhar (Rajasthan), and others — careful: Sambhar is in Rajasthan; UP’s sites include Upper Ganga River, Nawabganj, Saman, Samaspur, Sandi and Parvati Agra.
  • Single-site states often asked: Assam (Deepor Beel), Bihar (Kabartal), Goa (Nanda Lake), Manipur (Loktak), Meghalaya (Ramsar additions), Mizoram, Nagaland, Odisha (Chilika), Kerala (Vembanad), J&K/Ladakh (Hokera, Surinsar-Mansar, Tsomoriri, Wular, Hygam).
  • Border-state traps: Loktak (Manipur), Tsomoriri and Wular (Ladakh/J&K), Hokera (J&K), Point Calimere (Tamil Nadu coast).
  • Wular Lake — often misattributed; it is in the Kashmir Valley and one of Asia’s largest freshwater lakes.

The Montreux Record: Threatened Ramsar Sites

The Montreux Record is a register of Ramsar Sites where changes in ecological character have occurred, are occurring, or are likely to occur due to human interference. It is a voluntary mechanism, named after Montreux, Switzerland, where the recommendation was adopted in 1990.

  • India’s entries currently: Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur).
  • Chilika Lake was placed on the Montreux Record in 1993 but was removed in 2002 following successful restoration — a classic Prelims distinction.
  • Only two Indian sites are on the record at present — a favourite “how many” question.

Related Conventions and Laws: Wetlands (Conservation & Management) Rules 2017

Do not confuse the international treaty with India’s domestic framework:

  • Ramsar Convention (1971): International, non-binding; covers wetlands of international importance.
  • CBD (1992): Broader biodiversity treaty; Ramsar is a lead partner for inland-water biodiversity under it.
  • CITES (1973): Regulates trade in endangered species — nothing to do with wetland designation.
  • Wetlands (Conservation and Management) Rules, 2017: Notified under the Environment (Protection) Act, 1986; replaced the 2010 Rules; devolves wetland management to States/UTs, prohibits conversion, and set up the National Wetland Committee.
  • National Wetland Conservation Programme (NWCP): Launched 1985–86; later merged with the National Plan for Conservation of Aquatic Ecosystems (NPCA).

Other Key Wetland Terms: Wise Use, Ramsar Secretariat, World Wetlands Day

  • World Wetlands Day — 2 February: Marks the date the Convention was adopted in 1971; recognised by the UN from 2022.
  • Wise Use: The maintenance of a wetland’s ecological character, achieved through ecosystem approaches, within sustainable development.
  • Ramsar Secretariat: Based in Gland, Switzerland; administered by IUCN.
  • Ramsar Advisory Mission: Expert teams sent to Montreux-listed sites facing threats.

Famous Indian Ramsar Sites: One-Liner Facts

  • Largest Ramsar Site in India: Sundarbans Wetland (West Bengal).
  • Highest-altitude Ramsar Site: Tsomoriri (Ladakh).
  • Man-made wetland: Harike Lake (Punjab) — a reservoir at the confluence of Beas and Sutlej.
  • First two sites (1981): Chilika (Odisha) and Keoladeo (Rajasthan).
  • Brackish-water lagoon: Chilika — largest in Asia.
  • Floating phumdis: Loktak Lake (Manipur), home of Keibul Lamjao — the world’s only floating national park.
  • Largest freshwater lake (Ramsar): Wular (J&K).
  • Saltpan lake: Sambhar (Rajasthan) — largest inland saline lake.
  • Riverine site: Upper Ganga River (UP).
  • Mangrove site: Bhitarkanika (Odisha), Sundarbans (WB).

Previous-Year and Expected MCQ Patterns on Ramsar Sites

UPSC typically frames Ramsar questions as:

  • Matching pairs: Site ↔ State (e.g., “Match Loktak, Sambhar, Vembanad with Manipur, Rajasthan, Kerala”).
  • Montreux Record: “Which of the following is/are on the Montreux Record?” — answer is usually Keoladeo and Loktak only.
  • Convention facts: Depository (UNESCO), secretariat location (Gland), year/place of signing (1971, Iran), non-binding nature.
  • Statement-based questions: Testing the “1% waterbird population” or “20,000 waterbirds” criteria.
  • Count questions: Number of Ramsar Sites — verify the latest figure before the exam.
