Wetland

A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.

The Convention uses a broad definition of wetlands. It includes all lakes and rivers, underground aquifers, swamps and marshes, wet grasslands, peatland, oases, estuaries, deltas, and tidal flats, mangroves, and other coastal areas, coral reefs, and all human-made sites such as fish ponds, rice paddies, reservoirs, and salt pans.

Significance of Wetlands

  • Wetlands are a critical part of our natural environment. They mitigate floods, protect coastlines and build community resilience to disasters, reduce the impacts of floods, absorb pollutants and improve water quality.
  • Wetlands are critical to human and planet life. More than 1 billion people depend on them for a living and 40% of the world’s species live and breed in wetlands.
  • They are a vital source for food, raw materials, genetic resources for medicines, and hydropower.
  • 30% of land-based carbon is stored in peatland.
  • They play an important role in transport, tourism, and the cultural and spiritual well-being of people.
  • Many wetlands are areas of natural beauty and many are important to Aboriginal people.

Threats

  • As per the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services)’s global assessment wetlands are the most threatened ecosystem.
  • Wetlands are disappearing 3 times faster than forests due to human activities and global warming.
  • According to UNESCO, the threat to wetlands will have an adverse impact on 40% of the world’s flora and fauna that live or breed in wetlands.
  • Major threats: Agriculture, development, pollution, and climate change.

IPBES

  • IPBES is an independent intergovernmental body established to strengthen the science-policy interface for biodiversity and ecosystem services for the conservation and sustainable use of biodiversity, long-term human well-being, and sustainable development.
  • It was established in Panama City (US), in April 2012.
  • It is not a United Nations body.

Ramsar Convention on Wetlands

The term was coined when the International Treaty for the Conservation and Sustainable use of Wetlands was signed at a city of Iran called Ramsar in 1971.

It is also known as the Convention on Wetlands.

Ramsar Convention is a convention on wetlands that was signed in 1971 in the Iranian city of Ramsar. The negotiations for the convention started in the 1960s by the different countries and NGOs for the protection of wetland habitats of migratory waterbirds. Finally, it came into force in 1975.

February 2 is celebrated as International Wetlands Day as the Ramsar Convention was signed on February 2, 1971.

The Ramsar Convention works with the collaboration of the following organizations:

  1. International Union for Conservation of Nature (IUCN).
  2. Birdlife International.
  3. International Water Management Institute (IWMI).
  4. Wetlands International.
  5. Wildfowl & Wetlands Trust (WWT)
  6. WWF International

Under the “three pillars” of the Convention, the Contracting Parties commit to:

  1. work towards the wise use of all their wetlands;
  2. designate suitable wetlands for the list of Wetlands of International Importance (the “Ramsar List”) and ensure their effective management;
  3. cooperate internationally on transboundary wetlands, shared wetland systems, and shared species.

Ramsar Sites

Any Wetland site which has been listed under the Ramsar Convention that aims to conserve it and promote sustainable use of its natural resources is called a Ramsar Site.

At the time of joining the Convention, each Contracting Party undertakes to designate at least one wetland site for inclusion in the List of Wetlands of International Importance.

The inclusion of a “Ramsar Site” in the List embodies the government’s commitment to take the steps necessary to ensure that its ecological character is maintained.

The Ramsar sites are maintained in Montreux Record to track any major ecological changes that might affect any of the wetland sites positively or in a reverse way.

  • The Montreux Record is a register of wetland sites on the List of Ramsar wetlands of international importance 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.
  • At present, two wetlands of India are in Montreux Record:
    • Keoladeo National Park (Rajasthan) and
    • Loktak Lake (Manipur).
  • NoteChilka Lake (Odisha) was placed in the record but was later removed from it.

There are currently over 2,400 Ramsar Sites on the territories of 171 Ramsar Contracting Parties across the world. They cover over 2.5 million square kilometers, an area larger than Mexico.

  • India is a party to the Ramsar Convention. India signed under it on 1st February 1982.
  • Sundarbans is the largest Ramsar Site of India.
  • Chilika Lake (Orissa) and Keoladeo National Park (Rajasthan) were recognized as the first Ramsar Sites of India.
  • Renuka Wetland (Area – 20 ha) in Himachal Pradesh is the smallest wetland of India.
  • World’s First Ramsar site was identified in 1974, which was the Cobourg Peninsula in Australia.

Ramsar Sites in India

  • The Ramsar convention entered into force in India on 1 February 1982.
  • All wetlands, irrespective of their location, size, ownership, biodiversity, or ecosystem services values, can be notified under the Wetlands Rules 2017, except river channels, paddy fields, human-made waterbodies specifically constructed for drinking water, aquaculture, salt production, recreation, irrigation purposes, wetlands falling within areas covered under the Indian Forest Act, 1927, Forest (Conservation) Act, 1980, Wildlife (Protection) Act, 1972 and the Coastal Regulation Zone Notification, 2011.
  • India has over 7 lakh wetlands, covering 4.5% of the country’s area, yet none of the wetlands has been notified under domestic laws.
  • Wetlands are regulated under the Wetlands (Conservation and Management) Rules, 2017.

As of August 2022, there are 75 Ramsar Sites in India.

Wetland Conservation and Management Rules 2017 – Provisions

Wetlands are regulated under the Wetlands (Conservation and Management) Rules, 2017. The 2010 version of the Rules provided for a Central Wetland Regulatory Authority, but new Rules of 2017 replaced it with state-level bodies and created a National Wetland Committee, which functions in an advisory role.

The newer regulations removed some items from the definition of “wetlands” including backwaters, lagoons, creeks, and estuaries. Under the 2017 regulations process to identify the wetlands has been delegated to the States.

  • Constitution of State Wetland Authority: It has provisions for setting up of a State Wetland Authority (SWA) in every state and Union Territory to be headed by the Environment Minister of the respective state. It is to include a range of government officials. One expert each in the fields of hydrology, socioeconomics, landscape planning, fisheries, and wetland ecology. They will determine the ‘wise use principle’ that shall govern the management of wetlands. “Wise use” can be defined as the principles of sustainable use that are compatible with conservation.  This has led to the decentralization of powers. The SWA shall:
    • Develop a comprehensive list of activities to be regulated and permitted within notified wetlands and their zone of influence.
    • Recommend additional prohibited activities for specified wetlands.
    • Define strategies for better use of wetlands.
    • Recommend measures for wetland conservation and for raising awareness among its stakeholders and local communities with respect to the importance of wetlands.
    • Setting up of National Wetland committee: NWC will replace the Central Wetlands Regulatory Authority and shall be headed by the secretary to MoEFCC.
National Wetland Committee (NWC)

National Wetland Committee (NWC) will be set up for

  • Monitoring the implementation of rules
  • Advising the central government on appropriate policies and action programs for conservation and wise use of wetlands.
  • Recommending designation of Wetlands of International importance under the Ramsar Convention.
  • Advice collaboration with international agencies on issues related to wetlands.
  • Setting up a digital inventory: It is compulsory for all the state authorities to prepare a list of all the wetlands. Based on this, a digital inventory for wetlands will be created and updated every 10 years.
  • Prohibited activities: The rules prohibit the discharge of unwanted waste from villages, towns, cities, industries, etc., and solid waste dumping into the wetlands. Conversion of wetland area for non-wetland purposes, construction of a permanent structure on notified wetlands is banned.

These rules shall apply to wetlands notified by the State government, Central government, Union territory Administrations, and those classified as wetlands of international importance under the Ramsar convention.
