Wetlands — swamps, marshes, lagoons, mangroves and floodplain lakes — are among the most productive ecosystems on earth, yet they are disappearing faster than forests. They filter water, absorb floodwaters, store carbon and host millions of migratory birds every winter.

When a wetland is declared a Ramsar Site, it is formally recognised as a Wetland of International Importance. As of September 2026, India has 101 Ramsar Sites, the largest such network in Asia.

1. What is a Ramsar Site?

Official logo of the Ramsar Convention on Wetlands

A Ramsar Site is a wetland listed under the Ramsar Convention on Wetlands — an intergovernmental treaty adopted on 2 February 1971 in the city of Ramsar, Iran, and in force since 21 December 1975. It is the oldest of the modern global environmental agreements.

  • India joined on 1 February 1982, with Chilika Lake and Keoladeo National Park already designated on 1 October 1981.
  • World Wetlands Day is observed on 2 February, marking the signing of the Convention.
  • The Secretariat is headquartered at Gland, Switzerland (shared campus with IUCN and WWF).
  • The Convention rests on three pillars: wise use of all wetlands, designation of Wetlands of International Importance, and international cooperation.
  • In India, the nodal ministry is the Ministry of Environment, Forest and Climate Change (MoEFCC).

The Convention's central idea is "wise use" — sustainable human use of wetlands that maintains their ecological character, rather than fencing them off entirely.

Most-asked in exams

Ramsar Convention: 1971 · Ramsar, Iran · in force 1975 · India signatory 1 Feb 1982 · first two sites 1981 · World Wetlands Day 2 February. These five facts alone cover the majority of one-mark questions on this topic.

2. Why are wetlands so important?

Wetlands do an enormous amount of invisible work for the environment and for local livelihoods:

  • Flood control: they act as natural sponges, absorbing monsoon runoff and protecting downstream settlements. Kabar Taal in Bihar floods to a depth of about 1.5 m each monsoon, buffering a state where roughly 70% of land is flood-prone.
  • Groundwater recharge: water percolates slowly into aquifers, sustaining drinking water and irrigation.
  • Carbon sequestration: coastal wetlands and mangroves store "blue carbon" far faster per hectare than terrestrial forests.
  • Biodiversity & migration: Indian wetlands are critical stopovers on the Central Asian Flyway, used by birds travelling from Siberia, Mongolia and Central Asia.
  • Livelihoods: fisheries, agriculture, water chestnut cultivation and tourism. The East Kolkata Wetlands alone yield roughly 10,500 tonnes of fish a year and support around 50,000 people directly.
  • Natural waste treatment: East Kolkata's fish ponds treat the city's sewage using solar energy — saving the cost of a conventional treatment plant.

Wetlands are lifelines for waterbirds — like this kingfisher — and are vital stopovers on the Central Asian Flyway.

3. The 9 criteria for Ramsar designation

A wetland is not added automatically. It must satisfy at least one of nine criteria laid down by the Convention, grouped into two families.

Group A — Representative or unique wetland types

CriterionRequirement
1Contains a representative, rare or unique example of a natural or near-natural wetland type of the biogeographic region.

Group B — Sites of international importance for biodiversity

CriterionRequirement
2Supports vulnerable, endangered or critically endangered species, or threatened ecological communities.
3Supports populations of plants/animals important for maintaining the biological diversity of a particular biogeographic region.
4Supports species at a critical stage of their life cycle (breeding, nesting, moulting) or provides refuge in adverse conditions.
5Regularly supports 20,000 or more waterbirds.
6Regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.
7Supports a significant proportion of indigenous fish subspecies, species or families, life-history stages or interactions representative of wetland benefits.
8Is an important source of food for fishes, or a spawning ground, nursery and/or migration path.
9Regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal.
Memory hook: Criterion 5 = 20,000 waterbirds; Criterion 6 = 1% of a waterbird population; Criterion 9 = 1% of a non-bird species. Numbers 5, 6 and 9 are the ones exams quote.

8. Wetlands in danger: the Montreux Record

The Montreux Record is a register of Ramsar Sites where the ecological character has changed, is changing, or is likely to change because of pollution, construction, water diversion or other human interference. It was established by Recommendation 4.8 (1990) and is maintained as part of the Ramsar List. A site can only be added or removed with the consent of the country concerned.

India's two sites currently on the Record

  • Keoladeo National Park (Rajasthan) — added 1990; severe and persistent water shortage after upstream diversion of the Gambhir and Banganga rivers.
  • Loktak Lake (Manipur) — added 1993; ecological damage from the Ithai barrage, catchment deforestation and phumdi thinning.

Chilika Lake (Odisha) was placed on the Montreux Record in 1993 because of siltation and a choked sea mouth, and was removed in 2002 after the Chilika Development Authority restored the lagoon — the same year it won the Ramsar Wetland Conservation Award. It is India's flagship wetland-restoration success story.

Frequently confused: the Montreux Record lists 2 Indian sites today (Keoladeo and Loktak). Chilika was the third, but it has been off the list since 2002. Questions often ask for the current number — the answer is two.

9. Ramsar Site vs National Park vs Biosphere Reserve

FeatureRamsar SiteNational Park / WLSBiosphere Reserve
BasisInternational treaty (Ramsar Convention, 1971)Wildlife (Protection) Act, 1972UNESCO Man and the Biosphere (MAB) Programme
Declared byMoEFCC nominates; Ramsar Secretariat listsState government notificationCentral government; UNESCO recognition optional
Legal protectionNo automatic legal protection under Indian lawStrong statutory protectionRegulated through zonation, not a separate Act
FocusWetland ecosystems and wise useWildlife and habitat protectionConservation + development + research
Human activityPermitted under "wise use"Highly restrictedAllowed in buffer and transition zones
Key nuance: Ramsar designation is an international recognition, not an Indian legal status. Protection on the ground comes from the Wetlands (Conservation and Management) Rules, 2017, or from the wetland also being a National Park / Wildlife Sanctuary. Under the 2017 Rules, river channels, paddy fields and areas used for commercial activity are excluded from the definition of a wetland.

10. Conservation initiatives you should know

  • Wetlands (Conservation and Management) Rules, 2017 — replaced the 2010 Rules; created State Wetlands Authorities and a National Wetlands Committee (advisory).
  • National Plan for Conservation of Aquatic Ecosystems (NPCA) — merged scheme (2013) combining the National Lake Conservation Plan and National Wetlands Conservation Programme.
  • Amrit Dharohar — announced in the Union Budget 2023-24 to promote optimal use of wetlands, biodiversity and local income generation through ecotourism.
  • Mission Sahbhagita (2022) — a participatory, whole-of-society approach to wetland management.
  • Wetland City Accreditation (WCA) — a Ramsar scheme; Indore (MP) and Udaipur (Rajasthan) became India's first accredited Wetland Cities in 2025.
  • Save Wetlands Campaign and the Wetlands of India Portal (indianwetlands.in), run by MoEFCC.
  • Ramsar Wetland Conservation Award — won by the Chilika Development Authority in 2002.
