Quick Revision: The Ramsar Convention is an international treaty for the conservation and wise use of wetlands, crucial for biodiversity and migratory bird routes like the Central Asian Flyway, necessitating careful consideration in infrastructure development.
Why is this in the news?
The decision by the Tamil Nadu government to scrap the proposed Parandur airport project, thereby safeguarding the ecologically significant Vedanthangal and Karikili bird sanctuaries, has brought the imperative of wetland conservation and the judicious selection of infrastructure development sites into sharp focus. This decision underscores the importance of protecting Ramsar sites and the wider migratory bird landscape along the Central Asian Flyway.
Background
- The Vedanthangal and Karikili bird sanctuaries are recognised as Wetlands of International Importance under the Ramsar Convention.
- These sanctuaries serve as critical habitats for numerous migratory bird species traversing the Central Asian Flyway, a major global migratory route.
- The proposed Parandur airport project, intended to enhance air transport infrastructure, posed a potential threat to the ecological integrity of these bird sanctuaries due to associated developmental activities and environmental disturbances.
- The Central Asian Flyway (CAF) covers a large continental area of Eurasia and includes 30 countries, providing vital breeding, staging, and non-breeding grounds for migratory birds.
- The Ramsar Convention on Wetlands provides a framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.
- Environmental Impact Assessment (EIA) is a crucial tool for evaluating the potential environmental consequences of a proposed project or development, ensuring that these impacts are addressed prior to decision-making.
The Ramsar Convention on Wetlands
- The Ramsar Convention is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.
- It was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
- The Convention’s mission is ‘the conservation and wise use of all wetlands through local and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world’.
- Contracting Parties to the Convention commit to three main pillars: working towards the wise use of all their wetlands; designating suitable wetlands for the List of Wetlands of International Importance (the ‘Ramsar List’) and ensuring their effective management; and cooperating internationally on transboundary wetlands, shared wetland systems and shared species.
- India is a signatory to the Ramsar Convention and has designated numerous sites as Wetlands of International Importance.
- The ‘wise use’ concept of the Convention is defined as ‘the maintenance of their ecological character, achieved through the implementation of ecosystem approaches, within the context of sustainable development’.
- The Montreux Record, maintained as part of the Ramsar List, is a register of Wetland of International Importance where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution or other human interference.
