Background
The Ramsar Convention is an international treaty for the conservation and wise use of wetlands.
It was adopted in 1971 in Ramsar, Iran, and came into force in 1975.
Ramsar Sites are wetlands of international importance, recognised for their ecological, hydrological and biodiversity value.
Sukhna Lake is a man-made lake at the foothills of the Shivalik Hills and is an important ecological and recreational feature of Chandigarh.
Features
Biodiversity conservation: Provides habitat for resident and migratory birds, aquatic species and other wildlife.
Water security: Wetlands help regulate water flows and support groundwater recharge.
Flood management: They can absorb excess rainfall and reduce local flooding.
Climate regulation: Wetland vegetation and soils can store carbon.
International recognition: Ramsar status increases global visibility, scientific cooperation and conservation opportunities.
Ecotourism: Can promote responsible tourism and environmental awareness.
Challenges
Urbanisation: Encroachment and construction around the lake threaten its ecological integrity.
Pollution: Sewage, solid waste and agricultural runoff can degrade water quality.
Siltation: Soil erosion in the catchment reduces lake depth and storage capacity.
Invasive species: Non-native plants and animals can disrupt native ecosystems.
Water-level fluctuations: Changes in rainfall, runoff and catchment conditions affect the wetland.
Institutional coordination: Effective conservation requires cooperation among multiple departments and local communities.
Way Forward
Implement a science-based wetland management plan with clear conservation targets.
Strengthen sewage treatment and prevent untreated wastewater from entering the lake.
Restore the catchment area through soil conservation, afforestation and erosion control.
Regularly monitor water quality, biodiversity and invasive species.
Enforce buffer zones and prevent encroachment and unplanned development.
Encourage community participation, environmental education and responsible tourism.
Use Ramsar networks to promote international scientific cooperation and exchange best practices.
Conclusion
The designation of Sukhna Wetland as a Ramsar Site is an important step towards recognising and conserving India’s wetland ecosystems. However, international recognition must be backed by effective local management, pollution control and community participation to ensure the wetland’s long-term ecological sustainability.
