UPSC Editorial Analysis: Wetland Conservation

General Studies-3; Topic: Conservation, environmental pollution and degradation, environmental impact assessment.

Introduction

• The Meghalaya High Court, through a suo motu Public Interest Litigation (PIL), has taken up the conservation of wetlands in the state, highlighting the significance of these fragile ecosystems.
• The move by the High Court aligns with national and international efforts, including the Ramsar Convention on Wetlands (1971), which focuses on wetland conservation.

Wetland Conservation

• Wetlands are one of the most productive ecosystems and provide critical ecological services such as water purification, groundwater recharge, flood control, and biodiversity support.
• World Wetland Day (February 2), observed globally, aims to increase awareness about wetland conservation.
• The theme for 2024, “Protecting Wetlands for Our Common Future”, reinforces their importance for sustainable development.

Wetlands and Their Global Significance

• Wetlands as Critical Ecosystems

• • Wetlands constitute 6% of the Earth’s surface.
  • They provide 40.6% of global ecosystem services, making them crucial for biodiversity and climate regulation.
  • Serve as carbon sinks, reducing the impacts of climate change.
  • Act as natural flood buffers by absorbing excess water.
  • Support fisheries, agriculture, and livelihoods for millions of people.

• Global Decline of Wetlands

• • Over 50% of wetlands lost since 1900 due to human activities.
  • Between 1970 and 2015, 35% of global wetland area declined.
  • The Wetland Extent Trends (WET) index shows an annual loss of 0.78%, which is three times faster than the loss of natural forests.

Threats to Wetlands

• Anthropogenic Pressures

• • Urbanization & Industrialization: Expanding cities and industries lead to encroachments and pollution.
  • Agricultural Expansion: Wetlands are drained for farming, leading to habitat loss.
  • Infrastructure Development: Roads, dams, and ports disrupt wetland ecosystems.
  • Pollution: Industrial effluents, sewage, and solid waste degrade water quality.

• Climate Change Impacts

• • Rising temperatures alter wetland hydrology, leading to habitat loss.
  • Unpredictable rainfall affects wetland-dependent species.
  • Sea level rise threatens coastal wetlands like mangroves and estuaries.
  • Extreme weather events such as cyclones and floods degrade wetland ecosystems.

Conservation Efforts: International & National Context

• Ramsar Convention on Wetlands (1971)

• • The only global treaty focused on wetland conservation.
  • COP14 (2022) held in Wuhan and Geneva emphasized:
    • Integration of wetland conservation with Sustainable Development Goals (SDGs).
    • Collaboration with climate change policies (IPCC, UNFCCC).
    • Alignment with the UN Decade on Ecosystem Restoration.

• India’s Wetland Conservation Framework

• • India is a signatory to the Ramsar Convention.
  • The National Plan for Conservation of Aquatic Ecosystems (NPCA) provides financial and technical support for wetland conservation.
• Wetlands (Conservation and Management) Rules, 2017:
  • Prohibit conversion of wetlands for non-wetland uses.
  • Establish State Wetland Authorities (SWA) for conservation.
  • As of 2023, India has 75 Ramsar sites, covering 1.33 million hectares.

Meghalaya High Court’s Suo Motu PIL: A Landmark Initiative

• Rationale Behind the PIL

• • Meghalaya has rich wetland ecosystems that play a crucial role in maintaining biodiversity and water security.
  • Increased encroachments, mining, and unregulated tourism have threatened these wetlands.
  • The court intervened to ensure conservation measures are enforced effectively.

• Key Directives Issued

• • Creation of a Wetland Authority to oversee conservation.
  • Mapping and identification of wetlands in Meghalaya.
  • Strict regulation of encroachments and commercial activities.
  • Awareness programs to educate communities about wetland protection.

Way Forward

• Policy Interventions

• • Enforce Wetlands (Conservation and Management) Rules, 2017 more effectively.
  • Strengthen Ramsar site monitoring to prevent degradation.
  • Implement the Fifth Ramsar Strategic Plan for global collaboration.

• Community Participation & Traditional Knowledge

• • Involve local communities in conservation efforts.
  • Utilize indigenous knowledge for sustainable wetland management.
  • Promote eco-tourism to generate revenue while preserving wetlands.

• Scientific & Technological Approaches

• • Use of GIS & Remote Sensing to monitor wetland changes.
  • Develop Nature-Based Solutions (NbS) such as wetland restoration projects.
  • Enhance carbon sequestration efforts through wetland conservation.

• Climate Resilience & Adaptation

• • Incorporate wetlands into disaster risk reduction strategies.
  • Promote afforestation of mangroves and peatlands to enhance carbon storage.
  • Integrate wetlands in urban planning for sustainable cities.

Conclusion

• The suo motu PIL by the Meghalaya High Court is a crucial step toward wetland conservation in India.
• India must integrate legal, scientific, and community-based approaches to safeguard its wetlands.
• Strengthening wetland governance and international cooperation is essential to achieving sustainable development and climate resilience.
