Ramsar Wetlands in India: Significance and Conservation Explained

Understanding Ramsar Convention

The Ramsar Convention is an intergovernmental treaty. It provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. It was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975. India became a contracting party to the Ramsar Convention on February 1, 1982. The Convention's mission is 'the conservation and wise use of all wetlands through local, regional and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world'. Wetlands are vital for human survival and the environment. They provide essential ecosystem services like water purification, flood control, and habitat for diverse species. The Convention encourages countries to designate suitable wetlands for the List of Wetlands of International Importance, also known as Ramsar Sites.

Criteria for Designation

A wetland can be designated as a Ramsar site if it meets at least one of nine criteria. These criteria relate to the site's importance for specific biogeographical regions, its support for vulnerable or endangered species, or its role in supporting significant numbers of waterbirds or fish. For example, a site qualifies if it supports a significant proportion of indigenous sub-species, species or families of wetlands, or if it regularly supports 20,000 or more waterbirds. Another criterion is if it supports an appreciable assemblage of indigenous fish species. The designation aims to promote the conservation and wise use of these sites. Wise use means the maintenance of their ecological character, achieved through the implementation of ecosystem approaches, within the context of sustainable development. This involves managing wetlands to benefit both people and nature.

India's Ramsar Sites Overview

India has a significant number of Ramsar sites, reflecting its rich wetland biodiversity. As of early 2024, India has 80 Ramsar sites. These sites cover a vast geographical area across various states and union territories. Tamil Nadu has the highest number of Ramsar sites in India, with 16 sites. Uttar Pradesh follows with 10 sites. These sites include diverse wetland types such as lakes, rivers, mangroves, estuaries, and artificial wetlands like reservoirs. Some prominent examples include Chilika Lake in Odisha, which was the first Indian wetland of international importance designated in 1981, along with Keoladeo National Park in Rajasthan. The latest additions reflect India's commitment to wetland conservation and its efforts to meet international obligations under the Ramsar Convention. These designations help in attracting international support and expertise for wetland management.

Importance and Conservation Efforts

Ramsar sites are crucial for maintaining ecological balance and supporting livelihoods. They act as natural sponges, absorbing excess rainfall and reducing flood risks. They also filter pollutants, improving water quality. Many local communities depend on these wetlands for fishing, agriculture, and other resources. The designation as a Ramsar site brings international recognition and often leads to better conservation practices. India has implemented various schemes and policies for wetland conservation, such as the National Plan for Conservation of Aquatic Ecosystems (NPCA). This scheme aims at the conservation and management of wetlands and lakes in the country. The Ministry of Environment, Forest and Climate Change (MoEFCC) is the nodal agency for the implementation of the Ramsar Convention in India. Effective management plans are developed for each site, involving local communities and stakeholders to ensure sustainable use and protection.

Important Keywords Explained

Ramsar Conventionact

An international treaty for the conservation and sustainable use of wetlands. It provides a framework for national action and international cooperation for the wise use of wetlands and their resources. Adopted in 1971, it is one of the oldest global environmental agreements.

Wetlandconcept

Areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres.

Wise Useconcept

The maintenance of the ecological character of wetlands, achieved through the implementation of ecosystem approaches, within the context of sustainable development. This concept is central to the Ramsar Convention and guides management practices for designated sites.

Montreux Recordconcept

A register of Ramsar 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 maintained as part of the Ramsar List.
