Supreme Court Expands Mining Restrictions Near Wetland Reserves Nationwide
A new judicial clarification extends strict 10-km mining buffer zones to all Indian wetland conservation reserves. This decision moves beyond the original Uttarakhand-specific mandate to establish national parity for Ramsar sites.
Key takeaways
- Mining within 10 km of any wetland conservation reserve in India now requires prior approval from the NBWL or MoEFCC.
- The ruling extends protections originally established for the Asan Ramsar site in Uttarakhand to the entire country for legal parity.
- Ramsar designation commits India to ecological maintenance, though domestic laws previously lacked specific buffer zones for these sites.
- Current 2017 Wetland Rules are under Supreme Court scrutiny for removing explicit lists of prohibited activities.
Why It Matters
The Supreme Court has effectively tightened environmental oversight by requiring federal approval for mining projects near protected wetlands. By mandating that the 10-km restriction applied to the Asan Wetland Conservation Reserve now extends to similar sites across India, the court is addressing a perceived gap in the statutory protection of these international biodiversity hubs. This move impacts industrial activities near the nation's 101 Ramsar sites, particularly where state-level regulations might have been more permissive.
Background
The legal shift originates from a February 2024 interim order concerning the Asan Wetland Conservation Reserve in Uttarakhand. Located where the Asan and Yamuna rivers meet, this Ramsar site serves as a vital habitat for migratory birds. The Himachal Pradesh government challenged the scope of this order, arguing that since wetland conservation reserves lack the statutory buffer zones mandated for national parks, the restrictions should not apply to neighboring states. However, a Bench led by Chief Justice Surya Kant clarified that the protective principle is not geographically limited to Uttarakhand but applies to all notified wetland conservation reserves for the sake of parity.
Key Facts
- India currently maintains 101 Ramsar sites, following the inclusion of Glaw Lake in Arunachal Pradesh on August 3, 2026.
- The Supreme Court now requires prior approval from the National Board for Wildlife (NBWL) or the Ministry of Environment for mining within 10 km of these reserves.
- Unlike national parks and wildlife sanctuaries, which have a mandatory 1-km no-mining zone, wetlands were not previously subject to such a specific nationwide distance-based restriction under the 2017 Rules.
- The 2017 Wetlands Rules shifted regulatory authority to State Wetland Authorities, a framework currently facing a constitutional challenge for allegedly weakening protections compared to the 2010 regulations.
What Happens Next
The court has instructed federal authorities and the NBWL to determine if the Asan wetland boundaries reach into Himachal Pradesh. This finding will dictate whether the 10-km buffer applies immediately to specific mining sites in that state or if they will fall under the broader statutory framework. As the Supreme Court continues to evaluate the validity of the 2017 Wetlands Rules, this judicial intervention provides an interim safeguard that prioritizes ecological character over state-led decentralization.
