Urban expansion is increasingly threatening community-conserved ecosystems such as sacred groves and wetlands. Suggest a policy framework to reconcile urban growth with local biodiversity conservation.

Sacred groves and urban wetlands are community-conserved commons that survive on faith and custom rather than statute. India has notified only 57 Biodiversity Heritage Sites under Section 37 of the Biological Diversity Act, 2002 [1], leaving most such patches — like the four-acre Agaramthen grove near Tambaram, where a survey recorded 222 species — exposed to plotting, dumping and fragmentation [2]. Growth and conservation must therefore be reconciled through planning, not litigation.

Why the commons are slipping

• No legal identity: a "sacred grove" is a cultural, not a statutory, category; protection requires separate notification [1].
• Land-use conversion: farmland abutting groves and wetlands is converted into real-estate layouts, cutting off ecological corridors [2].
• Weak local enforcement of buffer and dumping norms by urban local bodies [2].

A four-pillar policy framework

• Legal anchoring: time-bound BHS notification by State Governments on State Biodiversity Board recommendation, with local-body consultation, while preserving existing community land-use rights [1]; parallel delineation of urban wetlands under the Wetlands (Conservation and Management) Rules, 2017, whose State Wetland Authorities can bar reclamation and dumping [3].
• Planning integration: make ecologically sensitive patches a non-negotiable "no-development" layer in master plans and CRZ/land-use zoning, mapped from People's Biodiversity Registers — over 2.7 lakh of which now exist nationally [1].
• Community stewardship: empower Biodiversity Management Committees with funds and functionaries, and recognise the customary role of resident and tribal communities (e.g. Irula settlements) as first-line custodians [1][2].
• Incentives and finance: extend the Amrit Dharohar approach of conservation-linked livelihoods and nature tourism [4], with ecosystem-service payments and municipal green budgeting.

Reconciliation lies in treating groves and wetlands as urban infrastructure — for water, micro-climate and culture — rather than as vacant land. A framework combining statutory notification, planning integration, community empowerment and incentives can let cities grow without erasing their ecological memory, advancing Article 48A and SDG 11 and 15.
