Supreme Court to examine if law is diluting India’s wetland count

What Happened

A bench of the Supreme Court has agreed to examine whether the Wetlands (Conservation and Management) Rules, 2017 — notified under the Environment (Protection) Act, 1986 — unlawfully narrow the definition of "wetland" and thereby reduce the number of sites receiving statutory protection.
Petitioners argued that the definition under Rule 2(g) of the 2017 Rules explicitly excludes certain categories of water bodies — including river channels, paddy fields, and certain human-made water bodies — in contrast to the Ramsar Convention's definition, which expressly includes both natural and artificial wetlands, whether permanent or temporary, without distinction.
Senior Advocate Gopal Sankaranarayanan and Advocate Anindita Mitra submitted on behalf of petitioners that 44 out of approximately 99 previously identified wetland sites lost regulatory protection when the 2017 Rules replaced the earlier framework.
The petitioners further argued that the Supreme Court had previously extended protection to nearly two lakh wetlands that had been identified, and the 2017 Rules undermined those safeguards.
The writ petition was filed under Article 32 of the Constitution, invoking the Court's original jurisdiction for enforcement of fundamental rights.

Static Topic Bridges

Ramsar Convention — International Framework for Wetland Protection

The Ramsar Convention (formally the Convention on Wetlands of International Importance Especially as Waterfowl Habitat) is an international treaty providing the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

Adopted: February 2, 1971, in Ramsar, Iran; came into force in 1975.
India acceded: February 1, 1982.
Ramsar definition of wetland (Article 1.1): "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." — This definition expressly includes artificial and temporary wetlands.
India currently has 94 Ramsar sites (as of 2026), the largest count in Asia.
The Ramsar Montreux Record is a register of Ramsar sites facing adverse ecological change; India has had sites listed and delisted from it.
Ramsar COP (Conference of the Parties) meets every three years; hosted in Gland, Switzerland (Ramsar Secretariat).

Connection to this news: The core of the petitioners' argument is that Rule 2(g) of India's 2017 domestic Rules contradicts Article 1.1 of the Ramsar Convention by excluding categories of wetlands (paddy fields, human-made water bodies) that the Convention explicitly includes — thereby reducing India's compliance with its international obligations.

Wetlands (Conservation and Management) Rules, 2017 — Domestic Regulatory Framework

The 2017 Rules were notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) under Section 3 and 25 of the Environment (Protection) Act, 1986, replacing the 2010 Rules.

Rule 2(g) definition: A wetland is defined as "an area of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with static or flowing water, including certain marine areas" — but specifically excluding:
River channels
Paddy fields
Human-made water bodies created for drinking water, irrigation, or aquaculture
Structures created for specified utilitarian purposes
State Wetland Authorities: The 2017 Rules transferred primary responsibility from a central authority to State Wetland Authorities (SWAs), headed by the respective state Environment Minister.
Wise use principle: Wetlands must be managed in accordance with the Ramsar "wise use" principle — sustainable use compatible with conservation.
Prohibited activities: Reclamation, solid waste dumping, industrial effluent discharge, construction, and introduction of invasive alien species are banned in wetland zones.
Comparison with 2010 Rules: The 2010 Rules identified specific wetlands centrally; the 2017 Rules broadened coverage to all ecologically significant wetlands but introduced the exclusions now under challenge.

Connection to this news: The petition's central challenge is that the 2017 Rules' exclusions — particularly of paddy fields and human-made water bodies — remove from protection a large class of wetlands that are both ecologically significant and Ramsar-compliant, potentially driving down India's effective wetland count.

Supreme Court's Original Jurisdiction — Article 32 and Environmental Petitions

The petitioners invoked Article 32 of the Constitution — the right to constitutional remedies, which Dr. B.R. Ambedkar called the "heart and soul of the Constitution." Article 32 empowers the Supreme Court to issue writs (habeas corpus, mandamus, prohibition, certiorari, quo warranto) for enforcement of fundamental rights.

Article 32 gives the Supreme Court original jurisdiction (not merely appellate) to directly hear petitions for enforcement of fundamental rights.
In environmental cases, the right to a clean environment has been read as part of the right to life (Article 21) by the Supreme Court — from Subhash Kumar v. State of Bihar (1991) and subsequent cases.
The precautionary principle and polluter pays principle have been recognised as part of India's environmental jurisprudence under Article 21 (Vellore Citizens Welfare Forum v. Union of India, 1996).
Environmental writ petitions have been used to expand green spaces, demarcate protected areas, enforce EIA clearances, and direct state action on pollution.

Connection to this news: By filing under Article 32, the petitioners frame wetland protection as a fundamental rights issue — arguing that dilution of the wetland definition under the 2017 Rules violates the right to a healthy environment under Article 21.

Wetland Ecosystem Services and Biodiversity Significance

Wetlands are among the most productive ecosystems on Earth, providing critical services — water regulation, carbon storage, biodiversity habitat, and livelihood support — that make their protection both ecologically and economically significant.

Wetlands cover approximately 4.63% of India's total geographical area (as per the National Wetland Inventory and Assessment by SAC/ISRO, 2011).
Ecosystem services: flood regulation (wetlands as natural sponges), groundwater recharge, water purification (natural filters), carbon sequestration (peatlands and mangroves as "blue carbon" sinks), and habitat for migratory birds (India lies on the Central Asian Flyway).
India's wetlands support approximately 400 species of birds, including migratory species protected under the Convention on Migratory Species (CMS) and the India-Australia Migratory Birds Agreement.
The distinction in the Ramsar Convention between natural and artificial wetlands is intentional — rice paddies and reservoirs can support significant biodiversity and perform hydrological functions comparable to natural wetlands.

Connection to this news: The exclusion of paddy fields and human-made water bodies from the 2017 Rules' definition is not merely a semantic issue — paddy fields cover vast areas and host significant biodiversity (including threatened species), making their exclusion ecologically consequential.
