Wetlands International

The global NGO working for wetland conservation
What is it?

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 Trap — Very Important!

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)

India’s centrally sponsored scheme for wetlands and lakes
What is 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.
💡 Key Achievement

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.

📌 UPSC Angle

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 first dedicated wetland regulations in India
Overview

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.
4

Wetlands (Conservation & Management) Rules 2017 Current

Stronger, decentralised — India’s current wetland law
Overview

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.
💡 What is Allowed vs Prohibited

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
📌 UPSC Angle

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 world’s only global treaty for a specific ecosystem
What is the Ramsar Convention?

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.
🔴 Current Affairs Update

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.

⭐ Ramsar Convention — UPSC Must-Know Facts

  • Signed: 2 February 1971 in Ramsar, Iran (in force: 21 December 1975)
  • Only global treaty dedicated to one specific ecosystem (wetlands)
  • Core principle: “Wise use” of all wetlands
  • India joined: 1 February 1982
  • India’s sites: 98 Ramsar Sites, 13.6 lakh+ hectares (Feb 2026)
  • World Wetlands Day: 2 February every year
  • Wetlands International = NGO (NOT Ramsar secretariat, NOT part of UN)
  • Montreux Record = Ramsar sites in ecological distress
  • COP = meets every 3 years

What is a Ramsar Site?

Designation criteria and implications
Definition

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.
🎯 What Happens After Designation?

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 Angle

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

Largest, smallest, first — and unique features
🥇 First

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.

🏆 Largest Area

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.

🔬 Smallest

Renuka Lake, Himachal Pradesh

India’s smallest Ramsar site. A high-altitude, sacred lake. Part of three HP Ramsar sites.

🦁 Tiger Mangrove

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.

⚠️ Montreux Record (India)

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.

🌊 Floating NP

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.

♻️ Unique Model

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.

☄️ Geology Rare

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.

🌊 Marine Ramsar (Rare)

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.

🔥 Free-flowing Estuary (Rare)

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.

🦢 Oldest Bird Sanctuary

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.

🌊 Asia’s Largest Oxbow

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.

🧪 Practice MCQs — Test Yourself
Practice
Q1. Which of the following is CORRECT about Wetlands International?
✅ Answer: (c)
Wetlands International is an independent NGO — it is NOT a UN body, NOT an intergovernmental organisation, and NOT the Ramsar secretariat. It is a not-for-profit global organisation headquartered in the Netherlands. UPSC has directly tested this by offering the false statement “Wetlands International is a bureau under UNEP” — that is incorrect. The Ramsar Convention has its own separate secretariat hosted in Gland, Switzerland.
Practice
Q2. The National Plan for Conservation of Aquatic Ecosystems (NPCA) was formed by merging which two schemes?
✅ Answer: (b)
NPCA = National Wetland Conservation Programme (NWCP) (launched 1985–86, for inland wetlands) + National Lake Conservation Plan (NLCP) (for lakes). By merging both, NPCA takes a holistic approach to all aquatic ecosystems. Under MoEFCC. States manage implementation since land is a state subject. The criteria for identifying sites under NPCA are the same as those under the Ramsar Convention.
Practice
Q3. Consider the following statements about the Wetlands (Conservation and Management) Rules 2017: 1. They replaced the Wetlands Rules of 2010. 2. Central Government directly manages all wetlands under these rules. 3. States are required to prepare wetland conservation plans. 4. These rules apply only to Ramsar-designated wetlands in India. Which of the above are correct?
✅ Answer: (c) — 1 and 3 only
1 ✅ Correct: The 2017 Rules replaced the 2010 Rules. 2 ❌ Wrong: The 2017 Rules DECENTRALISED management — State Wetland Authorities (headed by state Environment Ministers), NOT the Central Government, are the primary nodal authorities. This is a key change from 2010 where CWRA (Central Wetlands Regulatory Authority) had primary responsibility. 3 ✅ Correct: States must prepare wetland conservation plans under 2017 Rules. 4 ❌ Wrong: The 2017 Rules cover ALL ecologically significant wetlands — not just Ramsar sites. This wider coverage was an improvement over 2010.
Current AffairsUpdated 2026
Q4. As of February 2026, which Indian state has the HIGHEST number of Ramsar sites?
✅ Answer: (b) Uttar Pradesh — 11 sites
As of February 2026, Uttar Pradesh has 11 Ramsar sites — the highest in any single Indian state. These include Patna Bird Sanctuary, Bakhira Sanctuary, Haiderpur Wetland, Nawabganj, Parvati Arga, Saman, Samaspur, Sandi, Sarsai Nawar, Sur Sarovar, and the Upper Ganga River (a rare riverine Ramsar site). Tamil Nadu has 20 sites but many were added later — still, UP holds the record by number. India total: 98 sites, 13.6 lakh+ hectares.
Practice
Q5. Which of the following wetland-special feature pairs is CORRECTLY matched? 1. Kanwar Lake (Bihar) — Asia’s largest oxbow lake 2. Lonar Lake (Maharashtra) — Saltwater lake in a meteorite crater 3. East Kolkata Wetlands — World’s only floating national park 4. Vembanad-Kol (Kerala) — Longest lake in India
✅ Answer: (d) — 1, 2 and 4 only
1 ✅: Kanwar Lake (Bihar) = Asia’s largest oxbow lake. 2 ✅: Lonar Lake (Maharashtra) = saltwater lake in a basaltic meteorite crater — unique geology. 3 ❌ Wrong: The world’s only floating national park is Keibul Lamjao NP located on Loktak Lake (Manipur) — NOT East Kolkata Wetlands. East Kolkata Wetlands is famous for its sewage-fed aquaculture system. 4 ✅: Vembanad-Kol (Kerala) = longest lake in India; Kerala backwaters; also the second largest Ramsar site in India.
Practice
Q6. Which of the following Indian wetlands were in the Montreux Record as of 2026?
✅ Answer: (b) Keoladeo NP and Loktak Lake
The two Indian wetlands currently in the Montreux Record are: Keoladeo National Park (Rajasthan) — added due to water scarcity from upstream diversions cutting off water supply to the wetland; and Loktak Lake (Manipur) — added due to invasive weed overgrowth, encroachment on phumdis, and altered hydrology from the Loktak Hydroelectric Project. Chilika Lake was added to the Montreux Record in 1993 but was successfully removed in 2002 after restoration — a rare conservation success. This is a classic UPSC trap.
Practice
Q7. Consider the following statements about Ramsar designation criteria: 1. A wetland must regularly support 20,000 or more waterbirds to qualify. 2. A wetland must meet ALL nine Ramsar criteria to be designated. 3. A wetland designated as a Ramsar site must be a strictly protected area with no human activity. 4. A wetland can qualify if it supports an endangered or critically endangered species. Which is/are correct?
✅ Answer: (d) — Statements 1 and 4 are correct; 2 and 3 are wrong
1 ✅ Correct: Criterion 5 states a wetland qualifies if it regularly supports 20,000 or more waterbirds. 2 ❌ Wrong: A wetland needs to meet only ONE of the nine criteria — not all nine. 3 ❌ Wrong: Ramsar designation does NOT mean strictly protected/no human activity. The Ramsar Convention promotes WISE USE — sustainable use that maintains ecological character. Rice paddies and reservoirs are even included as wetlands. Human use is permitted sustainably. 4 ✅ Correct: Criterion 2 states a wetland qualifies if it supports vulnerable, endangered, or critically endangered species.
📜 UPSC Prelims PYQs — Official Past Questions
PYQUPSC 2019
Consider the following statements: 1. Wetlands International is a bureau under the United Nations Environment Programme (UNEP). 2. The mission of Wetlands International is to ensure that trade in wild plants and animals is not a threat to the conservation of nature. Which of the above is/are correct?
✅ Official Answer: (d) Neither 1 nor 2
Statement 1 ❌ Wrong: Wetlands International is NOT a bureau under UNEP. It is a completely independent, not-for-profit NGO — not part of the UN system at all. Statement 2 ❌ Wrong: Statement 2 describes the mission of TRAFFIC (Trade Records Analysis of Flora and Fauna in Commerce) — an organisation that monitors trade in wild plants and animals. Wetlands International’s mission is conservation and restoration of wetlands. This is a classic UPSC question testing whether students know the difference between Wetlands International (NGO) and UN bodies.
PYQUPSC 2019
If a wetland of international importance is brought under the ‘Montreux Record’, what does it imply?
✅ Official Answer: (a)
The Montreux Record is a register maintained under the Ramsar Convention listing sites “where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution or other human interference.” It is a conservation alert — NOT a heritage designation (option d = UNESCO World Heritage, a separate system). No automatic 5 km buffer zone applies (option b). India’s entries: Keoladeo NP (water scarcity) and Loktak Lake (weeds, encroachment, altered hydrology).
PYQUPSC 2022
“If rainforests and tropical forests are the lungs of the Earth, then surely wetlands function as its kidneys.” Which one of the following functions of wetlands best reflects the above statement?
✅ Official Answer: (b) Filtering and purifying water
Kidneys filter impurities from blood → Wetlands filter pollutants and excess nutrients from water draining into them. This is the water purification / filtration regulating ecosystem service. Wetlands trap sediments, absorb nitrogen and phosphorus (reducing eutrophication), filter pathogens, and clean water before it reaches rivers and groundwater. East Kolkata Wetlands naturally purifies Kolkata’s sewage — the most literal example of wetlands as “kidneys.” All options are real wetland functions but only (b) matches the kidney metaphor.
PYQUPSC 2020
With reference to India’s wetland conservation, consider the following statements: 1. India has the largest network of Ramsar Sites in South Asia. 2. The boundary of a Ramsar Site is automatically the same as the boundary of a National Park. Which of the above is/are correct?
✅ Official Answer: (a) 1 only
1 ✅ Correct: India (98 sites as of Feb 2026) has the largest Ramsar network in South Asia — more than any other South Asian country. 2 ❌ Wrong: A Ramsar site boundary is NOT automatically the same as a National Park boundary. They are completely separate designations under different frameworks. A wetland can be a Ramsar site without being a National Park, and vice versa. Some areas hold both designations (like Keoladeo) but their boundaries are independently defined. A Ramsar site can also include human settlements and agricultural land within its boundaries — unlike National Parks.
PYQUPSC 2014
Which one of the following is the best description of the term “Ecological character” as used in the context of the Ramsar Convention on Wetlands?
✅ Official Answer: (d)
The Ramsar Convention defines “ecological character” as “the combination of the ecosystem components, processes and benefits/services that characterise the wetland at a given point in time.” This includes the physical, chemical, and biological components AND the functions and services they provide. The Montreux Record is triggered when this ecological character changes adversely. The wise use principle aims to maintain ecological character. Options (a) and (c) are too narrow — counting species or measuring vegetation area doesn’t capture the full picture of a wetland’s ecological character.

No. Wetlands International is a completely independent, not-for-profit NGO. It is not part of the United Nations system, not a bureau under UNEP, and not the Ramsar Convention secretariat. The Ramsar Convention has its own separate secretariat hosted in Gland, Switzerland. Wetlands International works in partnership with governments and the Ramsar Convention but is institutionally independent. UPSC has directly tested this with the false statement “Wetlands International is a bureau under UNEP” — which is incorrect.
Key differences: 2010 Rules: Central Wetlands Regulatory Authority (CWRA) had primary authority; applied to specific identified wetlands; more centralised. 2017 Rules (current): State Wetland Authorities (SWA), headed by state Environment Ministers, are the primary nodal authorities — decentralised. Applies to ALL ecologically significant wetlands — not just identified ones. Mandatory wetland conservation plans by states. Wider definition of wetlands. No wetland can be converted without prior approval. Both are framed under the Environment (Protection) Act, 1986.
As of February 2026, India has 98 Ramsar sites covering 13.6 lakh+ hectares — the largest Ramsar network in South Asia. Uttar Pradesh has the most Ramsar sites of any single state (11 sites). Tamil Nadu has 20 sites but some are newer additions and TN leads among southern states. India joined Ramsar on 1 February 1982. From 2014 to 2024, India added 59 new sites — one of the most aggressive Ramsar designation campaigns in the world.
Two Indian Ramsar sites are currently in the Montreux Record: (1) Keoladeo National Park (Rajasthan) — added because upstream water diversion projects (Panchna Dam disputes) have severely reduced water supply to the wetland, threatening its ecological character and bird populations. (2) Loktak Lake (Manipur) — added due to invasive weed overgrowth (water hyacinth, phytoplankton), encroachment on phumdis (floating vegetation mats), and ecological changes from the Loktak Hydroelectric Project. Chilika Lake (Odisha) was added in 1993 but removed in 2002 after successful restoration — a rare conservation success story.
No. A Ramsar site is an international designation under the Ramsar Convention and is completely independent from National Parks, Wildlife Sanctuaries, or Biosphere Reserves (which are domestic designations under WPA 1972 or Central Government orders). A wetland can be a Ramsar site without being a NP or WLS. However, many Ramsar sites DO also carry other designations — for example, Sundarbans is simultaneously a Ramsar site + UNESCO World Heritage Site + Biosphere Reserve + Tiger Reserve. The boundaries of Ramsar sites and NPs can be different even for the same wetland area. Ramsar designation does NOT require strict no-human-activity protection — sustainable/wise use is permitted.
The Aghanashini Estuary (Karnataka) is notable as one of very few Ramsar sites designated for a free-flowing river estuary. Most estuaries in India are affected by upstream dam construction that regulates river flow. The Aghanashini River remains relatively undammed, making its estuary ecologically intact and rich in biodiversity — including mangroves, seagrasses, and fish nurseries. Its designation recognises the unique ecological value of free-flowing river-estuarine systems in an era when most such systems have been altered by development.
The Upper Ganga River (Uttar Pradesh) Ramsar site is notable because it is one of very few Ramsar sites designated for a riverine wetland — flowing water rather than a lake, lagoon, or marsh. Most Ramsar sites are standing water or marsh ecosystems. Designating a river section as a Ramsar site recognises that rivers and their floodplains are also critical wetland ecosystems providing biodiversity (Gangetic dolphin, gharial, migratory birds), water supply, fisheries, and flood regulation services. This is a relatively rare category in India’s Ramsar portfolio.
Mission Sahbhagita (Mission Participation) is India’s citizen science initiative for wetland conservation launched under MoEFCC. It mobilised over 2 million citizens to ground-truth more than 170,000 wetlands across India — verifying their location, extent, condition, and threats on the ground. This data fed into India’s national wetland inventory and helped identify wetlands for protection, management, and potential Ramsar designation. The mission demonstrates India’s commitment to the Ramsar Convention’s “wise use” principle through citizen participation and was highlighted as a global model of inclusive wetland governance at COP15.
