The Wetlands (Conservation and Management) Rules, 2017 were notified by the Ministry of Environment, Forest and Climate Change (MoEF&CC) under the Environment (Protection) Act, 1986. These rules replaced the previous 2010 framework, shifting the focus from centralized control to a decentralized model of “wise use” and state-led management.
Definition and Scope of Wetlands in India
The 2017 Rules define a wetland as an area of marsh, fen, peatland, or water—whether natural or artificial, permanent or temporary—with water that is static or flowing, fresh, brackish, or salt. This includes marine water areas where the depth at low tide does not exceed six meters.
Notable Exclusions from the Rules
The following categories are specifically excluded from the definition of wetlands under the 2017 Rules, even if they possess wetland-like characteristics:
- River channels and paddy fields.
- Human-made water bodies/tanks specifically constructed for drinking water purposes.
- Structures specifically constructed for aquaculture, salt production, recreation, and irrigation purposes.
- Wetlands falling under the Indian Forest Act (1927), Wildlife (Protection) Act (1972), and Coastal Regulation Zone (CRZ) Notification (2011).
Regulatory Framework and Authorities
The 2017 Rules established a two-tier institutional structure to oversee wetland conservation, emphasizing the role of State governments.
State/UT Wetlands Authority (SWA)
Every State and Union Territory is required to constitute an SWA, headed by the State’s Environment Minister.
- Composition: Includes secretaries from diverse departments such as Revenue, Water Resources, Fisheries, and Tourism.
- Expert Inclusion: Must include one expert each from the fields of wetland ecology, hydrology, fisheries, landscape planning, and socio-economics.
- Key Functions: Developing a comprehensive list of activities to be regulated or permitted, identifying “zone of influence” for wetlands, and creating a digital inventory of all wetlands.
National Wetlands Committee (NWC)
The NWC replaces the older Central Wetlands Regulatory Authority (CWRA) and acts primarily as an advisory body to the Central Government.
- Chairmanship: Secretary, MoEF&CC.
- Mandate: Monitoring the implementation of rules, advising on policies, and recommending wetlands for designation as Ramsar Sites (Wetlands of International Importance).
Prohibited and Regulated Activities
The rules operate on the principle of “Wise Use,” defined as the maintenance of the ecological character of a wetland through the implementation of ecosystem approaches.
| Category | Activities Mentioned |
| Prohibited | Encroachment of any kind; setting up or expansion of industries; manufacture/handling/disposal of construction and demolition waste; solid waste dumping; discharge of untreated effluents; poaching; and permanent construction (except boat jetties) within 50 meters from the mean high flood level. |
| Regulated | Subsistence-level biomass harvesting; sustainable culture fisheries; plying of non-motorized boats; and any other activity identified by the SWA that does not adversely change the ecological character. |
Comparative Analysis: 2010 vs. 2017 Rules
The transition to the 2017 Rules brought significant changes to how India governs its water bodies.
| Feature | 2010 Rules | 2017 Rules |
| Authority | Centralized (Central Wetlands Regulatory Authority). | Decentralized (State/UT Wetland Authorities). |
| Definition | Broad; included some man-made structures. | Specific; excludes river channels, paddy fields, and salt pans. |
| Appeals | Appeals could be made to the National Green Tribunal (NGT). | No specific mention of an appeal process within the rules (though NGT retains general jurisdiction). |
| Monitoring | Direct Central oversight on all notified wetlands. | States identify and notify wetlands; NWC provides only advisory guidance. |
Key Facts and Recent Developments (2024-2026)
- Wetland Inventory: As of 2026, India maintains a digital inventory of over 2 lakh wetlands (greater than 2.25 hectares) based on ISRO’s National Wetland Inventory and Assessment (NWIA).
- Ramsar Expansion: India has significantly increased its Ramsar Sites to 98 as of early 2026, the highest in Asia and third globally.
- Wetland City Accreditation: In a major urban governance milestone, Udaipur and Indore became India’s first Ramsar-accredited Wetland Cities in 2025.
- Amrit Dharohar: A scheme launched to promote the conservation values of Ramsar sites through public participation and “wise use” for local livelihoods.
- MISHTI Initiative: Focuses on mangrove restoration (a specific coastal wetland type) across 13 States/UTs to enhance shoreline resilience.
Important Trivia for UPSC
- Article 51-A (g): The rules align with the Fundamental Duty of citizens to protect and improve the natural environment, including lakes and rivers.
- Zone of Influence: This is the area surrounding a wetland where activities can directly impact the wetland’s ecosystem; its delineation is a mandatory task for the State Wetland Authority.
- Montreux Record: A register of Ramsar sites where changes in ecological character have occurred or are likely to occur. Currently, Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur) are the Indian sites on this record.
