Context:
India’s wetlands are facing increasing ecological degradation and disappearance, despite existing regulatory frameworks. On World Wetlands Day 2026 (February 2), the importance of traditional knowledge and community-based wetland management was highlighted to strengthen conservation efforts.
Key Highlights:
Status of Wetlands in India
- Nearly 40% of India’s wetlands have disappeared in the last three decades.
- Around 50% of the remaining wetlands show signs of ecological degradation.
- Wetlands are crucial for water security, biodiversity conservation, flood control, and climate resilience.
Government Policies and Regulatory Framework
- Wetlands (Conservation and Management) Rules, 2017
- Provide a legal framework for identification, notification, and management of wetlands.
- Emphasize state-level Wetland Authorities for conservation and monitoring.
- National Plan for Conservation of Aquatic Ecosystems (NPCA)
- Integrates conservation of lakes and wetlands through structured planning and monitoring.
- Coastal Regulation Zone (CRZ) framework
- Protects coastal wetlands and sensitive ecological areas.
- India currently has 98 Ramsar Sites, indicating global recognition of its wetlands.
Traditional Knowledge and Community Practices
- Historical water systems reflect sustainable wetland management:
- Kulams (Tamil Nadu) – Traditional irrigation tanks supporting agriculture and groundwater recharge.
- Kenis (Kerala) – Community-managed water storage structures.
- Such practices ensured long-term sustainability and water management.
Major Threats to Wetlands
- Encroachment and land conversion for urban infrastructure and agriculture.
- Hydrological disruptions due to dams, sand mining, and water diversion.
- Pollution from sewage discharge and industrial effluents.
- Eutrophication caused by excessive nutrient runoff.
Importance of Wetlands
- Act as natural flood buffers and disaster mitigation systems.
- Provide habitats for migratory birds and aquatic biodiversity.
- Support livelihoods, fisheries, and agriculture.
- Enhance groundwater recharge and water purification.
Relevant Prelims Points:
- Wetlands
- Land areas saturated with water permanently or seasonally, supporting distinct ecosystems.
- Include marshes, swamps, lakes, floodplains, mangroves, and coastal lagoons.
- Ramsar Convention (1971)
- International treaty for conservation and sustainable use of wetlands.
- Signed in Ramsar, Iran.
- India became a signatory in 1982.
- Ramsar Sites are wetlands of international importance.
- Wetlands (Conservation and Management) Rules, 2017
- Replaced earlier 2010 rules.
- Establish State Wetland Authorities.
- Prohibit activities like:
- Encroachment
- Solid waste dumping
- Industrial pollution
- Permanent construction within wetlands.
- Eutrophication
- Excessive nutrient enrichment (especially nitrogen and phosphorus) in water bodies.
- Leads to algal blooms, oxygen depletion, and death of aquatic organisms.
- Adaptive Management
- A flexible management approach where policies evolve based on learning from past outcomes.
Relevant Mains Points:
Importance of Wetlands in India
- Ecological significance
- Support rich biodiversity and migratory bird habitats.
- Water security
- Act as natural water storage and groundwater recharge systems.
- Disaster risk reduction
- Reduce impacts of floods, cyclones, and storm surges.
- Climate resilience
- Wetlands store carbon and regulate local climate.
- Socio-economic benefits
- Support fisheries, agriculture, tourism, and livelihoods.
Challenges in Wetland Conservation
- Weak enforcement of regulations
- Many wetlands remain unidentified or unnotified.
- Urban expansion and infrastructure development
- Leads to wetland reclamation and degradation.
- Pollution and untreated wastewater discharge.
- Fragmented governance
- Multiple agencies involved without coordinated management.
- Loss of traditional ecological knowledge.
Way Forward
- Recognize wetlands as a national public good essential for environmental security.
- Ensure proper demarcation and notification of wetland boundaries.
- Strengthen wastewater treatment infrastructure to prevent pollution.
- Protect hydrological connectivity between rivers, lakes, and wetlands.
- Launch a national capacity-building mission for wetland managers, focusing on:
- Hydrology
- Restoration ecology
- GIS and remote sensing
- Environmental law
- Community governance
- Promote community-led wetland stewardship and revival of traditional practices.
