On 5 June 2026, which is observed worldwide as World Environment Day, Prime Minister Narendra Modi welcomed India crossing a landmark century of Ramsar sites. The milestone came with the designation of the Jai Prakash Narayan Bird Sanctuary (Surha Tal), in Ballia district, Uttar Pradesh, as the country's 100th Wetland of International Importance under the Ramsar Convention. For NDA and CDS aspirants this is one of the most exam-relevant environment stories of the year, because wetlands, the Ramsar Convention and India's conservation architecture are tested almost every cycle. This article unpacks the news and then builds out the full static background you need.
What happened
- The Jai Prakash Narayan Bird Sanctuary (Surha Tal) in Ballia, Uttar Pradesh, became India's 100th Ramsar site.
- It is a freshwater wetland (an oxbow-style lake linked to the Ganga floodplain) that is exceptionally rich in avifaunal (bird) biodiversity, drawing large numbers of resident and migratory birds.
- The Prime Minister said the achievement reflects India's "unwavering commitment" to protecting its natural surroundings, and credited stronger wetland conservation driven by community participation, science, innovation and awareness.
Reaching 100 Ramsar sites makes India the country with the largest network of Ramsar sites in Asia, and among the highest in the world — a remarkable jump, given India had only around 26 sites in 2014.
What exactly is a wetland?
A wetland is land where water is the dominant factor controlling the environment — areas that are permanently or seasonally saturated with or covered by water. The Ramsar Convention defines them very broadly to include marshes, swamps, bogs, lakes, rivers, floodplains, mangroves, coral reefs, estuaries and even human-made wetlands such as reservoirs, tanks and salt pans.
Wetlands are among the most productive ecosystems on Earth and are often called the "kidneys of the landscape" (because they filter and purify water) and the "biological supermarkets" (because of the dense food webs they support). The vital ecosystem services they provide include:
- Water purification and groundwater recharge — wetlands trap sediments and break down pollutants.
- Flood control — they act like sponges, absorbing peak river flows and reducing flood damage.
- Carbon storage — peatlands and mangroves are powerful carbon sinks, storing more carbon per hectare than forests.
- Coastal protection — mangroves buffer storm surges, cyclones and tsunamis.
- Habitat and biodiversity — they are breeding and feeding grounds for fish, amphibians and especially migratory waterbirds.
- Livelihoods — fisheries, agriculture, tourism and water supply for millions of people.
The Ramsar Convention — the static backbone
The Ramsar Convention is an intergovernmental treaty that provides the framework for the conservation and "wise use" of wetlands and their resources. Key facts every aspirant must memorise:
- It was signed in the city of Ramsar, in Iran, in 1971, and came into force in 1975.
- It is one of the oldest modern environmental treaties and the only global treaty focused on a single ecosystem type.
- Its secretariat is based in Gland, Switzerland, and it works closely with the IUCN (International Union for Conservation of Nature).
- The treaty's central idea is "wise use" — sustainable use of wetlands for the benefit of people while maintaining their ecological character.
- Wetlands judged to be of international importance (against a set of nine criteria, relating to representative wetland types, threatened species and waterbird numbers) are listed as "Ramsar Sites" on the List of Wetlands of International Importance.
- The annual flagship awareness day is World Wetlands Day on 2 February, marking the date the Convention was signed.
India and Ramsar. India became a party to the Convention in 1982, when it designated its first two Ramsar sites — Chilika Lake (Odisha) and Keoladeo National Park (Rajasthan). From there the network has grown steadily, accelerating sharply in recent years to reach 100 sites in 2026. The states with the largest number of Ramsar sites are Tamil Nadu and Uttar Pradesh.
A few Ramsar sites are useful to remember by category:
- Largest / iconic lakes: Chilika (Odisha) — India's largest brackish-water lagoon; Wular (Jammu & Kashmir) — among the largest freshwater lakes; Loktak (Manipur) — famous for floating phumdis; Sambhar (Rajasthan) — largest inland salt lake.
- Bird sanctuaries: Keoladeo (Bharatpur, Rajasthan), Vembanad-Kol (Kerala) — the largest wetland in India, Point Calimere (Tamil Nadu).
- High-altitude: Tso Moriri and Tsomgo in the Himalayas.
The Montreux Record
The Montreux Record is a special register maintained under the Ramsar Convention listing those Ramsar sites where the ecological character has changed, is changing, or is likely to change due to pollution, encroachment or other human interference. It is essentially a "watch list" that flags wetlands needing priority conservation attention. From India, Keoladeo National Park and Loktak Lake have been placed on the Montreux Record. (Chilika was once on it but was removed after successful restoration — a frequently asked exam point.)
Why migratory birds matter here
Surha Tal, like many Indian wetlands, is a crucial stop on the Central Asian Flyway (CAF) — one of the world's major bird migration routes, stretching from the Arctic breeding grounds of Siberia down to the Indian subcontinent. India has adopted a National Action Plan for Conservation of Migratory Birds along the Central Asian Flyway. Wetlands provide the food, rest and breeding habitat these long-distance migrants depend on, which is why protecting them has both ecological and international significance.
India's wetland conservation framework
Beyond Ramsar listing, India conserves wetlands through several instruments worth knowing:
- Wetlands (Conservation and Management) Rules, 2017 — the legal framework regulating activities in notified wetlands, implemented through State Wetland Authorities.
- National Plan for Conservation of Aquatic Eco-systems (NPCA) — a centrally sponsored scheme (merging the earlier National Lake and Wetland Conservation Plans) under the Ministry of Environment, Forest and Climate Change (MoEFCC).
- Amrit Dharohar — a scheme to promote the conservation and wise use of Ramsar sites and generate local livelihoods and eco-tourism.
- "Save Wetlands Campaign" and Sahbhagita (participation) mission — community awareness drives.
- Namami Gange Programme — river and floodplain rejuvenation that has directly improved wetlands like Surha Tal that lie within the Ganga basin.
Threats to wetlands
Despite their value, wetlands are among the most threatened ecosystems in the world, lost faster than forests. The main threats are encroachment and conversion for agriculture and construction, pollution from sewage and industrial effluent, invasive species (such as water hyacinth), siltation, and the impacts of climate change. This is why legal protection (the Wetlands Rules, 2017), the Montreux Record watch-list, and community-based conservation through awareness campaigns are all essential to keep India's 100 Ramsar sites ecologically healthy.
Why it matters
- Ecological security: wetlands underpin water security, flood resilience and climate adaptation — directly relevant to disaster management.
- Biodiversity conservation: they protect migratory and resident species and maintain the Central Asian Flyway.
- Soft power and diplomacy: crossing 100 Ramsar sites strengthens India's global environmental leadership ahead of climate and biodiversity negotiations.
- High-yield GK: the figures (1971, Iran, 1982, Chilika & Keoladeo first, 2 February) are repeatedly tested.

FAQ
Q1. What makes a wetland a "Ramsar site"? It must qualify as a Wetland of International Importance under the Convention's nine criteria — for example, by being a representative or rare wetland type, supporting threatened species, or regularly hosting large numbers of waterbirds — and must be formally designated by the country.
Q2. When is World Wetlands Day, and why that date? 2 February — the day the Ramsar Convention was signed in 1971. Each year it has a global theme highlighting a different value of wetlands.
Q3. Why are wetlands called the "kidneys of the landscape"? Because they filter and purify water, trapping sediments and breaking down pollutants, much as kidneys clean blood — while also recharging groundwater and controlling floods.
Q4. How is India's Ramsar growth significant? Going from about 26 sites in 2014 to 100 in 2026 gives India the largest Ramsar network in Asia, reflecting expanded conservation effort, community participation and schemes like Amrit Dharohar and the Wetlands Rules, 2017.
