Ramsar Convention on Wetlands
Ramsar Convention is formally known as Convention on Wetlands of International Importance, especially as Waterfowl Habitat. It was signed on 2 February 1971 at city of Ramsar in Iran. That date is celebrated as World Wetland Day now.
Objectives
Ramsar Convention has two-fold objectives viz. Conservation and sustainable utilization of wetlands; and stop the encroachment and loss of wetlands. This treaty is not a legal binding treaty and is not a part of UN & UNESCO conventions.
Key Facts
As of 2023, there are above 2400 Ramsar sites around the world of which maximum are in UK. The Largest area covered by Ramsar Sites is in Canada. Ramsar secretariat is hosted by IUCN World Conservation Union in Gland, Switzerland.
How does it work?
First of all, a country joins the Ramsar Convention. With this, it gets itself listed into the international effort for the conservation and wise use of wetlands. Once a country has joined, there are three commitments which it has to fulfill as obligations:
- It has to designate at least one of its wetlands into the List of Wetlands of International Importance called “Ramsar List”. Once that is done, it can later designate more such wetlands.
- The above designation has to be based upon criteria that take into account the ecology, botany, zoology, limnology (freshwater science) or Hydrology. Thus, not every wetland becomes a Ramsar site but only those which have significant values related to these fields.
- The country has to make all efforts for wise use and conservation of the Ramsar Sites in its territory. Being a part of Ramsar convention gives it access to know-how of conservation in different parts of the world.
- If the ecological character of any Ramsar wetland has changed, or is changing or is likely to change as the result of technological developments, pollution or other human interference, it will inform without delay to the Ramsar Secretariat.
- Once this information has been provided to Ramsar Secretariat, it will do the following
- Enter the wetland into its Montreux Record (a record for such sites where there has been or likely to be adverse ecological change)
- Send a Ramsar Advisory Mission to the country. This mission will analyse the situation and define how to tackle the threats to the wetland.
- Once the appropriate measures have been taken, the site will be removed from Montreux Record.
The Ramsar convention also makes the countries cooperate in matters of conservation of the trans-boundary wetlands, shared water systems, and shared or migratory species, and to share expertise and resources with Parties less able to meet their commitments.
Criteria for Identifying Wetlands of Importance
As per the Convention, wetlands are defined broadly to include lakes, rivers, marshes, estuaries, deltas, tidal mudflats, mangroves, coral reefs etc. A wetland can qualify as a Ramsar Site by fulfilling at least one of nine listing criteria. These criteria assess the ecological, botanical, zoological and hydrological importance of the wetland. These criteria are as follows:
- The site contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.
- The site supports vulnerable, endangered, or critically endangered species or threatened ecological communities. This particularly highlights the importance of the site for conserving biological diversity.
- The site supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region. This emphasizes the role of the wetland in the broader ecological context.
- The site supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions. This includes areas that are critical for breeding, feeding, or resting.
- The site supports 20,000 or more waterbirds. This is a significant number, indicating the site’s importance as a habitat for these birds.
- The site supports 1% of the individuals in a population of one species or subspecies of waterbird. This highlights the site’s role in the survival of specific bird populations.
- The site supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.
- The site is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.
- The site regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species. This could include mammals, reptiles, amphibians, crustaceans, and insects.
Ramsar Sites in India
By becoming a signatory in 1982, India has committed to designate its wetlands of global importance as Ramsar Sites. Out of over 2,400 Ramsar Sites globally, India now has 75 within its territory. They are as follows:

Important Facts on Ramsar Sites in World
First Ramsar Site
The first wetland to be designated as a Ramsar Site was the Cobourg Peninsula in Australia, declared in 1974. This marked the beginning of a global effort to recognize and protect vital wetland habitats.
Largest Ramsar Site
The largest Ramsar Site is the Ngiri-Tumba-Maindombe in the Democratic Republic of Congo, covering an area of about 6.57 million hectares. This massive wetland plays a crucial role in maintaining regional biodiversity.
Smallest Ramsar Site
The smallest Ramsar Site is the Monaco Marine Reserve in Monaco, with an area of just 0.04 hectares. Despite its size, it’s significant for the conservation of marine biodiversity in the Mediterranean.
Highest Ramsar Site
The highest Ramsar Site in the world is the Laguna Colorada in Bolivia, located at over 4,300 meters above sea level. This high-altitude saline lake is known for its striking red color and is a vital breeding ground for Andean flamingos.
Wetland of International Importance for Birds
The United Kingdom’s Rutland Water, a Ramsar Site, is famous for being an important overwintering and breeding site for ospreys, which were reintroduced here after a 150-year absence in England.
Urban Ramsar Site
The East Kolkata Wetlands in India are a unique example of an urban wetland that provides essential services such as wastewater treatment and is a source of vegetables and fish for the city, highlighting the harmony between human activity and nature conservation.
Cultural and Historical Significance
The Garaet El Ichkeul in Tunisia, a Ramsar Site, is not only ecologically significant but also of great cultural and historical importance, with the Ichkeul National Park having been a hunting ground for Roman emperors.
Subterranean Wetland
The Sistema Sac Actun in Mexico, one of the world’s largest underwater cave systems, is also a Ramsar Site. This subterranean wetland is home to a diverse range of aquatic species and holds significant geological and archaeological value.
Shared Ramsar Sites
The Prespa Park, shared by Albania, Greece, and North Macedonia, is a transboundary Ramsar Site. This collaboration highlights the importance of international cooperation in the conservation of shared ecological resources.
Artificial Wetland Site
The Hadejia-Nguru Wetlands in Nigeria, although partly natural, include large areas of seasonally flooded land which have been modified for rice cultivation, demonstrating the inclusion of human-modified but ecologically significant sites under the Ramsar Convention.
Country with maximum number of wetlands under the Ramsar Convention
The United Kingdom has designated 175 Wetlands of International Importance under the Ramsar Convention, the highest number of any single country. The Ramsar Convention is an international treaty aimed at conserving wetland habitats. The large number of designated Ramsar Sites in the UK reflects the country’s strong commitment to identifying and protecting ecologically vital wetlands.
Country with Greatest surface area under Ramsar sites
Bolivia has the greatest surface area protected under the Ramsar Convention globally. Although Bolivia has only 7 designated Ramsar Sites, these span a massive 135,288 square kilometers. Most of Bolivia’s Ramsar wetlands are located within three vast lowland nature reserves that harbor exceptional biodiversity and provide refuge for rare and endemic freshwater species as well as indigenous communities. Thus, while having few Ramsar Sites, Bolivia protects immense spans of critical wetland ecosystems.
