Supreme Court widens wetland ground-truthing to all water bodies
The Supreme Court, in an order dated 12 October 2026, extended the ground-truthing and demarcation required under the Wetlands (Conservation and Management) Rules, 2017 to other water bodies as well. States must file affidavits on their progress within four weeks. The bench observed that water bodies supplying drinking water fall within the right to life under Article 21.
Syllabus: GS2 · Separation of Powers; Prelims · Environment & Ecology; GS3 · Environment & Conservation
Why this matters for UPSC
GS3 conservation: Prelims can ask what the Wetlands (Conservation and Management) Rules, 2017 define, exclude and prohibit, and who chairs each wetland body. GS2 and GS3 Mains can ask about Article 21 and weak enforcement.
Why it matters
A village pond, a temple tank or a marsh on a city's edge can store rain, recharge wells and soften floods. Yet it can be filled in and built over if no map shows where it begins and ends. Until a boundary is checked on the ground and written down, officials have no line to enforce, and a builder or a dumping contractor faces little risk. By pulling other water bodies into the exercise and tying drinking water to the right to life, the court has made the survey a matter of citizens' rights, not paperwork. Families that depend on a local pond or lake for water stand to gain most.
Prelims pointers

Practise a UPSC-style question
With reference to the definition of 'wetland' in the Wetlands (Conservation and Management) Rules, 2017, consider the following statements:
1. It includes areas of marine water whose depth at low tide does not exceed six metres.
2. It includes river channels and paddy fields that hold water for part of the year.
3. It covers areas that are natural or artificial, and permanent or temporary.
Which of the statements given above is/are correct?
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Show the answer
Answer: (c) 1 and 3 only
Answer: (c) 1 and 3 only. Rule 2(g) is broad, but it expressly leaves river channels and paddy fields out.
Statement 1: correct. Rule 2(g) counts marine water up to six metres deep at low tide as wetland.
Statement 2: incorrect. Rule 2(g) excludes river channels, paddy fields and tanks built for drinking water.
Statement 3: correct. Rule 2(g) covers marsh, fen, peatland or water, natural or artificial, permanent or temporary.
Eliminate: Statement 2 is the surest: the exclusion of paddy fields is the best-known part of the definition. Out: (a), (b), (d).
Trap: Wrong scope. Statement 2 sounds right because paddy fields and rivers hold water, but the Rules narrow the legal definition.
Remember: Wetland under Rule 2(g): up to 6 m at low tide; not rivers, paddy fields or drinking-water tanks.
