Q. Discuss the significance of the Supreme Court's extension of the Asan wetland mining-buffer principle to all wetland conservation reserves in India for environmental federalism. (15 marks, 250-350 words)

Asan Conservation Reserve, notified under Section 36A of the Wildlife (Protection) Act, 1972 and designated Uttarakhand's first Ramsar site in July 2020 [1], has been shielded by a judicially crafted 10-km mining restraint. In August 2026, a Bench headed by CJI Surya Kant clarified that this buffer applies to all wetland and community conservation reserves nationally [5] — converting a site-specific order into a pan-India ecological norm.

From site-specific order to national standard - The 2015 Uttarakhand High Court ban was modified by the Supreme Court in February 2024 to permit mining in the buffer only with NBWL Standing Committee and MoEFCC clearance [5]. - Himachal Pradesh sought exemption, arguing an Uttarakhand-centric restriction could not bind it; the Court invoked parity, holding the "entire Himalayan terrain" must be governed uniformly [5].

Significance for environmental federalism - Uniform floor of protection: prevents "regulatory arbitrage", where mining shifts across a State border to escape a neighbour's stricter regime — relevant given the contested Uttarakhand–Himachal boundary [5]. - Centralising tilt: clearance rests with NBWL/MoEFCC rather than State forest departments, deepening Union oversight over a State subject-adjacent activity (mining, land) under the concurrent environmental domain. - Judicially-led federal norm-setting: strengthens the Wetlands (Conservation and Management) Rules, 2017 architecture of State Wetland Authorities [3], which has suffered weak enforcement — reports before the Court flagged leases and stone crushers inside Asan's buffer [5]. - Calibrated, not absolute: the buffer is rebuttable where an expert committee finds no such reserve in a State [5], preserving space for State-specific facts.

Federal frictions - Mapping and notifying every conservation reserve across India's 90-plus Ramsar sites and wider wetland inventory [2] is an administrative burden on States. - Livelihood and revenue costs of halted leases fall on States, while the norm is set centrally.

The ruling reframes environmental federalism as cooperative ecological stewardship rather than territorial bargaining. A sustainable path lies in States completing wetland delineation under the 2017 Rules, backed by MoEFCC's National Plan for Conservation of Aquatic Ecosystems [4], so that uniform standards are met through capacity-building rather than litigation — advancing Article 48A duties and SDG 6 and 15.
