Wetlands International
Wetlands International is an independent, not-for-profit, global organisation working for the conservation and restoration of wetlands and their resources. It works at the field level to develop and mobilise knowledge and practical experience for wetland conservation advocacy.
🔑 Key Facts
- Nature: An NGO — it is NOT a UN body, NOT an intergovernmental organisation, and NOT part of the Ramsar Convention secretariat.
- Headquarters: Ede, the Netherlands.
- Works with: Governments, international organisations, local communities, and scientists to develop and mobilise knowledge for wetland conservation.
- Key databases: Maintains the Ramsar Information System and the Global Lakes and Wetlands Database (GLWD).
- India connection: Works with MoEFCC and state governments on wetland inventory and conservation projects across India.
UPSC has directly asked: “Is Wetlands International an intergovernmental organisation?” — Answer: NO. It is an NGO. A past UPSC question stated “Wetlands International is a bureau under UNEP” — that is FALSE. It is a completely independent NGO, not part of the UN system. This distinction is frequently tested.
National Plan for Conservation of Aquatic Ecosystems (NPCA)
The National Plan for Conservation of Aquatic Ecosystems (NPCA) is a centrally sponsored scheme under the Ministry of Environment, Forest and Climate Change (MoEFCC). It was formed by merging two earlier schemes:
- National Wetland Conservation Programme (NWCP) — launched in 1985–86, covering inland wetlands.
- National Lake Conservation Plan (NLCP) — covering lakes.
🔑 Key Features of NPCA
- Covers both wetlands AND lakes — a holistic aquatic ecosystem approach.
- Implements scientific management, ecological restoration, pollution abatement, and community participation.
- Central Government coordinates and provides financial and technical assistance; State Governments manage and implement (since land resources belong to states).
- Under NWCP (predecessor), 115 wetlands were identified by MoEF as requiring urgent conservation.
- Criteria for identifying wetlands of national importance under NPCA are the same as those prescribed under the Ramsar Convention.
- Constitutes State Wetland Authorities in each state — headed by the state’s Environment Minister.
- State Wetland Authorities determine the “wise use principle” governing wetland management in each state.
Chilika Lake (Odisha) is the most celebrated success of India’s wetland conservation programme. Chilika was added to the Ramsar Montreux Record in 1993 due to ecological deterioration — siltation, weed overgrowth, and reduced salinity. After concerted restoration efforts under the wetland conservation programme, its ecological character improved so much that it was removed from the Montreux Record in 2002 — a rare conservation success story.
Know: NPCA = merger of NWCP + NLCP under MoEFCC. State governments manage wetlands because land is a State subject. Identification criteria same as Ramsar. Chilika restoration = NPCA success. The Mission Sahbhagita (citizen participation) and Save Wetlands Campaign are implemented alongside NPCA.
Wetlands (Conservation & Management) Rules 2010
The Wetlands (Conservation and Management) Rules, 2010 were India’s first dedicated national regulations for wetland protection, framed under the Environment (Protection) Act, 1986. They established a legal framework for identifying and regulating wetlands across India.
🔑 Key Features of 2010 Rules
- Central Government had primary authority — a Central Wetlands Regulatory Authority (CWRA) was established.
- Required prior environmental clearance for activities in or around wetlands.
- Prohibited activities included: conversion of wetland area for non-wetland uses, reclamation, setting up industries, solid waste dumping.
- Limited to specific identified wetlands — did not cover all wetlands comprehensively.
- Widely criticised for being too centralised, slow, and not involving states adequately.
- Eventually replaced by the stronger 2017 Rules.
Wetlands (Conservation & Management) Rules 2017 Current
The Wetlands (Conservation and Management) Rules, 2017 replaced the 2010 Rules. They decentralise wetland governance, giving states more responsibility while strengthening the regulatory framework for all wetlands in India — not just specific identified ones. Framed under the Environment (Protection) Act, 1986.
🔑 Key Changes from 2010 to 2017
- Decentralisation: Central authority replaced by State Wetland Authorities (SWA) in each state/UT — headed by the state’s Environment Minister. States now have primary responsibility.
- Wider definition: The 2017 Rules cover a broader set of wetlands — not just identified national wetlands. All wetlands of ecological significance are covered.
- Expanded prohibited activities: In wetlands and their catchment areas: reclamation, construction, solid waste dumping, industrial effluent discharge, introduction of invasive alien species, and any activity that would harm ecological character are banned without prior approval.
- Wetland Conservation Plans: States must prepare wetland conservation plans for all significant wetlands.
- Inventory and mapping: States must maintain a wetland inventory within their territory.
- No conversion: No wetland can be converted to any other land use without prior approval.
- Wise use principle: Conservation plans must adhere to the Ramsar Convention’s wise use principle.
Prohibited (without prior approval): Reclamation, construction, industrial discharge, solid waste dumping, introducing invasive species, mining, altering hydrology. Allowed (with regulation): Fishing and aquaculture (traditional), grazing, agriculture (within buffer zones), ecotourism, education and research activities — provided they don’t harm the ecological character of the wetland.
⭐ Rules 2010 vs 2017 — Quick Comparison
- 2010: Central authority (CWRA) | Limited to specific wetlands | More centralised
- 2017: State Wetland Authorities | All ecologically significant wetlands | Decentralised | Wider coverage | Wetland conservation plans mandatory
- Both are under: Environment (Protection) Act, 1986
- Current applicable rules: 2017 Rules
Key facts: 2017 Rules replaced 2010 Rules. State Wetland Authorities — NOT Central — are now the nodal authorities. States are headed by their Environment Ministers. Wetland conservation plans are mandatory under 2017 Rules. This connects to UPSC questions on federalism (land as state subject) and environmental governance decentralisation. Also: Ramsar sites get additional international protection beyond these domestic rules.
Ramsar Convention on Wetlands
The Ramsar Convention on Wetlands is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. It was signed on 2 February 1971 in Ramsar, Iran and came into force on 21 December 1975.

🔑 Core Principles of the Ramsar Convention
- Wise use: Maintenance of the ecological character of wetlands, achieved through ecosystem approaches, within sustainable development. “Wise use” does NOT mean no use — it means sustainable, managed use.
- Three pillars: (1) Designate Ramsar Sites and manage them well. (2) Plan for and regulate wise use of all wetlands. (3) Cooperate internationally on transboundary wetlands.
- The Ramsar List: Sites of international importance are listed, and countries commit to maintaining their ecological character.
- Montreux Record: A sub-list of Ramsar sites undergoing adverse ecological change due to human interference — a conservation alert register.
- COP (Conference of Parties): Policy-making organ that meets every 3 years to review implementation and adopt resolutions. COP15 was held in 2022 in Wuhan, China (later moved to Zimbabwe).
🔑 India and the Ramsar Convention
- India joined the Ramsar Convention on 1 February 1982.
- India is one of the most active contracting parties — added 59 new sites between 2014 and 2024.
- India submitted a resolution at Ramsar COP15 (Zimbabwe, 2023) titled “Promoting Sustainable Lifestyles for the Wise Use of Wetlands” — adopted with overwhelming support.
- Mission Sahbhagita — India’s campaign that mobilised over 2 million citizens to ground-truth 170,000+ wetlands.
- Nodal Ministry: MoEFCC is the nodal ministry for Ramsar implementation in India.
Ramsar COP15 (2022–2023): The 15th Meeting of the Ramsar Convention was originally scheduled in Wuhan, China but had to be moved. It concluded with new resolutions on wetland restoration, protection of peatlands, and climate-wetland linkages. India’s resolution on sustainable lifestyles was adopted. India now has 98 Ramsar Sites (as of February 2026) covering 13.6 lakh+ hectares — the largest Ramsar network in South Asia and among the largest globally.

What is a Ramsar Site?
A Ramsar Site is a wetland designated as being of international importance under the Ramsar Convention. Once a country designates a wetland as a Ramsar site, it commits to maintaining the site’s ecological character and reporting on its condition. Inclusion on the Ramsar list is a commitment, not just an honour.
🔑 Criteria for Designation as a Ramsar Site (9 Criteria)
A wetland qualifies if it meets at least ONE of the following nine criteria:
- Criterion 1: Contains a representative, rare, or unique wetland type.
- Criterion 2: Supports vulnerable, endangered, or critically endangered species, or threatened ecological communities.
- Criterion 3: Supports populations of plant/animal species important for biodiversity.
- Criterion 4: Supports plant/animal species at critical stages of their life cycles, or during stress.
- Criterion 5: Regularly supports 20,000 or more waterbirds.
- Criterion 6: Regularly supports 1% of the individuals in a population of a waterbird species.
- Criterion 7: Supports a significant proportion of indigenous fish subspecies, species, or families; represents wetland benefits and/or values contributing to global biological diversity.
- Criterion 8: Is an important source of food for fishes; spawning ground, nursery, or migration path.
- Criterion 9: Regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.
The host country must: (1) Maintain the ecological character of the site. (2) Report to the Ramsar Convention Secretariat on the site’s condition. (3) Promote “wise use” within the site. (4) If ecological character deteriorates, the site may be placed on the Montreux Record — triggering international scrutiny and obligation to restore. Designation does NOT mean strict no-go zone — sustainable use is permitted.
UPSC asks about the criteria for Ramsar site designation — especially Criterion 5 (20,000 waterbirds) and Criterion 6 (1% of a waterbird species population). These are the most commonly tested criteria. Also: A Ramsar site is NOT automatically a National Park or Biosphere Reserve — these are separate designations. A wetland can hold multiple designations simultaneously (e.g., Sundarbans is a Ramsar site + UNESCO World Heritage Site + Biosphere Reserve + Tiger Reserve).

Special & Notable Ramsar Sites of India
Chilika Lake, Odisha
India’s first Ramsar site (1981). Asia’s largest brackish water lagoon (1165 sq km). Supports 1.5 lakh+ fishermen. Was in Montreux Record — removed in 2002 after successful restoration. Famous for Irrawaddy dolphins and flamingoes.
Sundarban Wetland, West Bengal
India’s largest Ramsar site by area. World’s largest mangrove forest. UNESCO World Heritage Site. Only mangrove habitat for Royal Bengal Tiger. Shared with Bangladesh.
Renuka Lake, Himachal Pradesh
India’s smallest Ramsar site. A high-altitude, sacred lake. Part of three HP Ramsar sites.
Sundarbans — unique
World’s only mangrove habitat for tigers. World’s largest Ramsar site in India. Biosphere Reserve + Tiger Reserve + UNESCO WHS + Ramsar Site — one of the most multi-designated protected areas in the world.
Keoladeo NP + Loktak Lake
Currently in Montreux Record. Keoladeo: water scarcity from upstream diversions. Loktak: weed overgrowth, encroachment. Chilika was removed from the Record in 2002 after restoration.
Loktak Lake, Manipur
Home of Keibul Lamjao — world’s only floating national park. Famous for phumdis (floating mats of vegetation). Last natural habitat of Sangai (brow-antlered deer). In Montreux Record.
East Kolkata Wetlands, West Bengal
Sewage-fed aquaculture system that treats Kolkata’s wastewater while producing fish and vegetables. A model of ecological-economic sustainability. Often used as an example of wise use of wetlands.
Lonar Lake, Maharashtra
World’s only saltwater lake in a basaltic rock crater formed by a meteorite impact. A unique geological and ecological wetland. Favoured in UPSC geology questions.
Gulf of Mannar, Tamil Nadu
One of the very few marine Ramsar sites in India. Part of Gulf of Mannar Marine National Park and Biosphere Reserve. Rich in seagrass, coral reefs, and dugongs.
Aghanashini Estuary, Karnataka
Rare example of a free-flowing river estuary as a Ramsar site. Most estuaries are modified by dams. Aghanashini’s relatively undammed state makes it ecologically valuable.
Vedanthangal, Tamil Nadu
India’s oldest bird sanctuary and one of Tamil Nadu’s 20 Ramsar sites. Critical roosting and breeding ground for migratory waterbirds.
Kanwar Lake, Bihar
Asia’s largest oxbow lake (formed when a river changes course and cuts off a bend). Important biodiversity hotspot in the Gangetic floodplain. A UPSC favourite.
