Answer

Wetlands, vital ecosystems saturated with water, play a crucial role in flood control, groundwater recharge, and biodiversity conservation. However, a study by Wetlands International South Asia (WISA) found that India lost nearly one-third of its natural wetlands between 1970 and 2014 due to urbanization, agricultural expansion, and pollution. Despite being a signatory to the Ramsar Convention, regulatory gaps and weak enforcement continue to threaten their survival.

Rapid Wetland Loss Threatens India’s Ecosystem

• Urbanization and Infrastructure Expansion: Rapid urban growth has led to encroachment, reclamation, and conversion of wetlands into residential and industrial zones.
  For example: Mumbai has lost 71% of its wetlands from 1970 to 2014 due to urban expansion and infrastructure projects.
• Agricultural and Aquaculture Expansion: Wetlands are being drained for farming and aquaculture, reducing water retention and biodiversity.
  For example: East Kolkata wetlands shrank by 36% from 1991 to 2021, largely due to unregulated aquaculture and agriculture.
• Pollution and Waste Dumping: Industrial effluents, sewage, and solid waste have degraded water quality, making wetlands unsuitable for biodiversity and ecological functions.
  For example: Chennai has lost 85% of its wetlands, with untreated sewage being a major contributor.
• Weak Policy Implementation: Despite Ramsar designations and legal protections, weak enforcement and poor inter-agency coordination hinder conservation efforts.
  For example: Only 8% of India’s wetlands are designated as Ramsar sites, and many face encroachments despite legal protections.
• Climate Change Impact: Rising temperatures, erratic rainfall, and sea-level rise accelerate wetland degradation, altering their hydrology and ecosystem services.
  For example: The Sundarbans wetlands are shrinking due to increased salinity and coastal erosion from rising sea levels.

Multidimensional Challenges in Wetland Conservation

• Lack of Comprehensive Mapping and Monitoring: Inadequate data on wetland extent, degradation rates, and biodiversity loss affects effective policymaking.
  For example: The last National Wetland Atlas (2017-18) lacks real-time monitoring mechanisms for wetland health assessment.
• Conflicting Land Use Policies: Wetlands fall under multiple jurisdictions (urban, forest, and agricultural departments), leading to governance conflicts.
  For example: In many cities, wetlands are classified as wastelands, allowing their legal conversion for real estate projects.
• Limited Community Participation: Local communities often lack awareness and incentives to conserve wetlands, leading to unregulated use.
  For example: In Chilika Lake, Odisha, overfishing and illegal shrimp farming have contributed to ecological decline despite Ramsar status.
• Encroachments and Illegal Constructions: Private real estate and infrastructure projects encroach on wetlands, reducing natural flood control capacity.
  For example: The flooding of Gurugram in 2023 was exacerbated by wetland destruction due to unchecked urban expansion.
• Insufficient Financial and Institutional Support: Funding for wetland restoration is limited, with conservation programs receiving low priority in state budgets.
  For example: The National Plan for Conservation of Aquatic Ecosystems (NPCA) remains underfunded and lacks effective on-ground implementation.

Innovative Strategies to Mainstream Wetland Protection into India’s Development Planning

• Integrating Wetlands into Urban Planning: Incorporate wetlands into Smart City projects and Master Plans to enhance blue-green infrastructure.
  For example: New Delhi’s Najafgarh Jheel restoration is being integrated into city planning as a flood mitigation and biodiversity zone.
• Incentivizing Wetland Conservation through Payments for Ecosystem Services (PES): Introduce financial incentives for farmers and local communities to protect and restore wetlands.
  For example: The East Kolkata Wetlands Management Plan promotes eco-tourism and sustainable fisheries as economic alternatives.
• Strengthening Wetland Legislation and Governance: Establish a single nodal agency for wetland management, with stricter enforcement of conservation laws.
  For example: The Chilika Development Authority in Odisha has successfully implemented community-led conservation models to restore degraded wetlands.
• Adopting Technology for Real-time Monitoring: Use GIS, remote sensing, and AI-based predictive models for wetland health assessments and illegal encroachment detection.
  For example: The Wetlands of India Portal has been launched to track and map wetland degradation using satellite data.
• Mainstreaming Wetlands into Climate Action Plans: Recognize wetlands as carbon sinks and include them in India’s National Adaptation Plan for climate resilience.
  For example: The Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI) scheme supports coastal wetland restoration under India’s climate commitments.

“Wetlands: Nature’s Lifeline, Future’s Hope” , integrating wetland conservation into urban planning, leveraging geo-spatial technology, and enforcing community-led eco-restoration can reverse degradation. Strengthening the legal framework, incentivizing sustainable livelihoods, and embedding wetland services into national accounting will ensure their resilience. A synergistic approach blending policy, technology, and grassroots participation is imperative for a water-secure, biodiversity-rich India.
