India's wetland network hits 93: Bihar's new ramsar sites signal a conservation push

In a significant boost to its ecological conservation efforts, India has designated two new Wetlands of International Importance in Bihar, elevating its total count of Ramsar Sites to 93. The newly added sites, Gokul Reservoir in Buxar and Udaipur Lake in West Champaran, underscore the growing recognition of wetlands as critical assets for biodiversity, water security, and climate mitigation.

This development is a direct outcome of India’s invigorated focus on wetland conservation, most notably through the Amrit Dharohar initiative. Launched as part of the 2023-24 Union Budget, this scheme aims to promote the unique conservation values of Ramsar Sites through community participation and generate sustainable livelihoods via ecotourism over a three-year period.

The two new sites in Bihar are both oxbow lakes, crescent-shaped water bodies formed by the meandering of rivers.

• Gokul Reservoir, located on the southern edge of the Ganga River, is a vital local water source.
• Udaipur Lake, nestled within the Udaipur Wildlife Sanctuary, serves as a crucial wintering ground for migratory birds, including the vulnerable Common Pochard (Aythya ferina).

Fun Fact: Wetlands are often called “biological supermarkets” because they support a vast diversity of life. They cover less than 9% of the Earth’s surface but are home to almost 40% of the world’s plant and animal species.

The Ramsar Convention: A Global Treaty for Local Action

The foundation for this global conservation effort is the Ramsar Convention on Wetlands, an intergovernmental treaty adopted in the Iranian city of Ramsar in 1971. It provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. A wetland must meet at least one of nine specific criteria to be designated as a Wetland of International Importance.

To remember the three core pillars of the Ramsar Convention’s mission, use the following mnemonic:

Mnemonic: W.I.S.E.

• Wise Use of all wetlands.
• International Cooperation.
• Site Designation on the Ramsar List.
• Effective management.

Analogy: Think of wetlands as the planet’s kidneys. Just as kidneys filter waste from our blood, wetlands filter pollutants, sediments, and excess nutrients from our water systems, providing clean water for both humans and wildlife.

Critical Policy Appraisal

While India’s expanding Ramsar network is a success, significant challenges remain in ensuring their long-term health and viability.

Statistic: According to the Global Wetland Outlook, wetlands are disappearing three times faster than forests. Nearly 35% of the world’s wetlands have been lost since 1970.

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis

The primary international legal framework is the Ramsar Convention on Wetlands (1971). In India, the principal domestic legislation is the Wetlands (Conservation and Management) Rules, 2017, notified under the Environment (Protection) Act, 1986.

UPSC Integration: Connecting the Dots

• Environment & Geography: Directly linked to biodiversity, ecosystem services, hydrology (flood control, groundwater recharge), and climate change (as carbon sinks). The formation of wetlands like oxbow lakes is a key concept in fluvial geomorphology.
• Polity & Governance: Involves international relations (treaty obligations), federalism (Centre-State coordination), and environmental governance through bodies like the Ministry of Environment, Forest and Climate Change (MoEFCC) and State Wetland Authorities.
• Economy: Connects to the “blue economy,” sustainable tourism, fisheries, and the economic valuation of ecosystem services. The Amrit Dharohar scheme is a prime example of linking conservation with economic activity.

Expert Analysis: Future Impact & Policy Relevance

The future of India’s water security and climate resilience is inextricably linked to the health of its wetlands. As climate change intensifies extreme weather events, the role of wetlands in flood mitigation and as buffers against droughts will become even more critical. Policies like Amrit Dharohar represent a crucial shift from a purely conservationist approach to an integrated model that involves local communities as primary stakeholders. The long-term success will depend on robust monitoring, scientific management, and the political will to curb encroachment and pollution, making wetland governance a key area of policy focus for decades to come.

Prelims Practice Question (MCQ)

Q. Which of the following Ramsar sites in India is a man-made reservoir and is also known as Maharana Pratap Sagar? a) Loktak Lake, Manipur b) Pong Dam Lake, Himachal Pradesh c) Kabar Taal, Bihar d) Deepor Beel, Assam

Answer: (b) Pong Dam Lake, Himachal Pradesh. Explanation: Pong Dam Lake, located in Himachal Pradesh, is a large reservoir created in 1975 by the construction of the Pong Dam on the Beas River. It was declared a Ramsar site in 2002. Loktak Lake is a natural freshwater lake, Kabar Taal is an oxbow lake, and Deepor Beel is a permanent freshwater lake.

Mains Sample Question

Q. (15 Marks) While India has made significant strides in expanding its network of Ramsar sites, the effective conservation and management of these vital ecosystems face persistent challenges. Critically analyze the efficacy of India’s wetland protection framework, suggesting measures to bridge the gap between policy intent and on-ground reality, with special reference to the ‘Amrit Dharohar’ scheme.
