Wetlands as a national public good

Why in the News?

World Wetlands Day 2026, observed on February 2 under the theme “Wetlands and traditional knowledge: Celebrating cultural heritage”, has renewed attention on India’s wetlands as ecological, cultural, and economic lifelines. The discussion, amplified by experts like Soumya Swaminathan, highlights the urgent need to treat wetlands not as wastelands but as national public goods essential for water security, climate resilience, biodiversity, and livelihoods.

India’s rapid urbanisation, infrastructure expansion, and hydrological disruptions have intensified wetland degradation, making policy reform and community stewardship central to environmental governance.

Background

Wetlands in India historically evolved through a blend of traditional ecological knowledge and community governance:

• Tamil Nadu’s tank irrigation (kulam) systems created cascading water networks
• Kerala’s kenis in Wayanad supported ritual and drinking water systems
• Andhra Pradesh’s wetlands sustained traditional fishing economies

Wetlands function as:

• Natural flood buffers
• Groundwater recharge zones
• Biodiversity hotspots
• Carbon sinks
• Livelihood systems

Policy architecture already exists:

• Wetlands (Conservation and Management) Rules, 2017
• National Plan for Conservation of Aquatic Ecosystems (NPCA)
• Coastal Regulation Zone (CRZ) framework
• Ramsar Convention on Wetlands commitments

India currently has 98 Ramsar sites, indicating global recognition but also a responsibility to ensure effective stewardship.

Despite this, India has lost nearly 40% of its wetlands in three decades, and about half of the remaining wetlands show ecological stress.

Features 

Ecological Infrastructure

• Wetlands act as nature-based infrastructure:
• Flood mitigation
• Water purification
• Climate adaptation buffers
• Coastal protection (mangroves, lagoons)

They provide ecosystem services that would cost billions if replicated artificially.

Cultural and Social Commons

Wetlands are embedded in:

• Rituals
• Traditional livelihoods
• Community identity
• Local governance systems

They represent living heritage rather than isolated ecosystems.

Economic Security

Wetlands support:

• Fisheries
• Agriculture
• Tourism
• Drinking water systems

Their degradation translates into hidden economic losses.

Disaster Risk Reduction

Floodplains, mangroves, and urban wetlands absorb shocks from:

• Cyclones
• Floods
• Storm surges
• Extreme rainfall

They are low-cost climate insurance systems.

Challenges

Encroachment and Land Conversion

• Urbanisation and infrastructure expansion have erased or fragmented wetlands. Many are treated as vacant land for real estate.

Hydrological Disruption

• Dams
• Channelisation
• Sand mining
• Groundwater over-extraction

These alter natural water flows, destroying wetland ecology.

Pollution and Eutrophication

• Untreated sewage, industrial effluents, and agricultural runoff convert wetlands into waste sinks, collapsing biodiversity.

Governance Fragmentation

• Multiple agencies manage land, water, forests, and urban planning with poor coordination, leading to policy silos.

Capacity Constraints

State wetland authorities often lack:

• Technical staff
• GIS and hydrology expertise
• Enforcement capacity
• Community engagement frameworks

Way Forward

Watershed-Scale Governance

• Shift from isolated beautification projects to basin-wide wetland programmes integrating hydrology, land use, and biodiversity.

Boundary Notification and Legal Protection

• Clear demarcation of wetland boundaries
• Public access to maps
• Participatory dispute resolution
• Legal buffer zones

Treat Wastewater Before Wetland Entry

• Wetlands must not substitute for sewage treatment. Constructed wetlands can complement but not replace treatment plants.

Restore Hydrological Connectivity

• Reopen feeder channels
• Prevent blockages
• Regulate extraction
• Protect catchments

Conclusion

Wetlands are not decorative landscapes; they are public ecological assets underpinning India’s water security, disaster resilience, and cultural continuity. The real reform lies in shifting from short-term projects to long-term programmes, from cosmetic beautification to ecological functionality, and from departmental silos to watershed governance.
