Supreme Court to examine if law is diluting India’s wetland count

UPSC CSE Context

Why in News: Supreme Court admitted a petition challenging the constitutional validity of the definition of 'wetlands' in the Wetlands Rules, 2017.

Syllabus Connection: Environment and Ecology: Wetland conservation, Ramsar Convention, environmental laws and judicial interventions.

Exam Relevance: Tests understanding of environmental governance, treaty obligations, and the principle of non-regression in Indian law.

Core Issue

2017 Wetlands Rules exclude most human-made wetlands, violating Ramsar Convention and diluting protection.

Key Development: Supreme Court issued notice to Centre on petition arguing Rule 2(g) of 2017 Rules contradicts Ramsar definition and Supreme Court's 2017 order.

Stakeholders:

• Union Government
• Petitioners (Ravindra Sinha et al.)
• State Wetland Authorities

Static Knowledge

High-Value Background:

• Ramsar Convention defines wetlands broadly, including natural and artificial, permanent or temporary.
• India has 94 Ramsar sites; 39 are human-made, which would lose protection under 2017 Rules.

Exam Linkage:

• Useful for questions on wetland conservation, environmental rule of law, and India's international commitments.

Concepts in Context:

• Principle of non-regression: prohibits weakening existing environmental protections.
• National Wetland Atlas (2011) classifies wetlands by function, not origin.

Institutions and Mechanisms:

• Central Wetland Authority (removed in 2017 Rules)

Dynamic Analysis

Legal and Constitutional

• Petition argues 2017 Rules violate Article 21 (right to environment) and Article 253 (implementing treaties).
• Exclusion of human-made wetlands contradicts Ramsar Convention, which India ratified.
• Supreme Court's 2017 order in M.K. Balakrishnan case mandated protection of all 2,01,503 wetlands identified in National Wetland Atlas.
• 2017 Rules replace 2010 Rules, which had adopted Ramsar definition fully.

Environmental Governance

• Removal of Central Wetland Authority decentralizes oversight, potentially weakening enforcement.
• Deletion of prohibited activities schedule leaves room for reclamation and construction.
• Functional classification (hydrology, biodiversity) replaced by origin-based classification, undermining ecological continuity.

International Relations

• Non-compliance with Ramsar Convention could damage India's credibility as a responsible party.
• Ramsar designation brings international scrutiny; dilution may invite criticism.
• India's commitment to global biodiversity targets (e.g., Aichi targets) may be questioned.

Prelims Takeaways

• Ramsar Convention definition includes both natural and artificial wetlands.
• National Wetland Atlas, 2011 identifies 2,01,503 wetlands in India.

Mains Value Addition

Arguments:

• 2017 Rules violate principle of non-regression by reducing protection from 2010 Rules.
• Excluding human-made wetlands ignores their ecological value (flood moderation, groundwater recharge).
• Decentralization without central oversight may lead to inconsistent state-level protection.
• Judicial intervention is necessary to align domestic rules with international obligations.

Examples:

• 39 of India's 94 Ramsar sites are human-made (e.g., Loktak Lake, Chilika Lake) and would lose protection.

Data Points:

• 94 Ramsar sites in India as of 2026.

Counterpoints:

• Government may argue that excluding artificial wetlands reduces regulatory burden on development projects.
• State-level oversight may be more responsive to local needs than centralized authority.
• Some artificial wetlands (e.g., aquaculture ponds) may have limited biodiversity value.

Way Forward

• Supreme Court should strike down Rule 2(g) and restore Ramsar-compliant definition.
• Re-establish Central Wetland Authority with clear mandate and resources.
• Adopt functional classification of wetlands based on National Wetland Atlas.
• Amend 2017 Rules to include explicit prohibitions on reclamation and construction in all wetlands.
