Wetlands and Ramsar

Wetland functions

Wetlands are areas where water covers or saturates soil seasonally or permanently, creating distinct hydrology, soils and biota. They include marshes, swamps, floodplains, lakes, mangroves, estuaries, lagoons, peatlands and some human-made wetlands such as reservoirs and rice paddies. They recharge groundwater, moderate floods, retain sediment, cycle nutrients, store carbon, support fisheries and provide habitat for migratory birds. A wetland is not simply a permanent lake; shallow seasonal and coastal systems can qualify ecologically.

Ramsar Convention

The Convention on Wetlands was adopted at Ramsar, Iran, in 1971 and entered into force in 1975. It is an intergovernmental treaty for conservation and “wise use” of all wetlands through cooperation. A Ramsar Site is a wetland designated by a contracting party for the List of Wetlands of International Importance. Designation does not automatically make it a national park or prohibit all human use.

Criteria relate to rare or representative wetland types, threatened species, biodiversity, waterbirds, fish and ecological functions. Parties should maintain ecological character and plan wise use. The Montreux Record lists Ramsar sites where ecological character has changed, is changing or is likely to change because of pollution, technological development or other interference. It is not a list of every polluted wetland and is not the same as delisting.

India

India joined in 1981. Himalayan, Gangetic, peninsular, coastal and island wetlands are represented. Chilika is a brackish coastal lagoon with birds and fisheries; Loktak is known for floating phumdis; Keoladeo is a managed freshwater bird habitat; Wular and Sundarban are other important examples. Ramsar recognition can coexist with another legal designation. India’s Wetlands (Conservation and Management) Rules, 2017 provide a domestic framework and state wetland authorities.

Prelims tips

Remember 1971 adoption, 1975 entry into force and India’s 1981 membership. Wise use means sustainable use compatible with ecological character, not zero use. Distinguish Ramsar status from national park status and Montreux Record from delisting. Do not assume every reservoir or protected area is automatically a Ramsar Site.

Prelims revision checklist

Identify the definition first, then connect it to the relevant institution, date, process and example. Do not treat a scientific mechanism as a policy instrument, an international label as automatic domestic legal status, or a rank as ownership. Watch absolute words such as “always” and “only”; they are rarely correct unless part of a formal definition. In current-affairs questions, apply the stable principle and verify changing figures or variants from an official source.

Analogy

Wetlands and Ramsar — Analogy

A wetland is nature’s sponge, filter and nursery: it stores floodwater, cleans it and supports young fish and birds. Ramsar status marks international importance, not total exclusion of people.
