Quick Revision: The Vembanad-Kole wetlands, a Ramsar site in Kerala, face severe anthropogenic and climatic pressures, necessitating integrated governance, scientific research, and community-led conservation to sustain their ecological and livelihood functions.

Why is this in the news?

The Chief Minister of Kerala has underscored the urgent need for ecological protection of the Vembanad lake system, a Ramsar-listed wetland under severe anthropogenic and climatic stress. The call comes during a commemorative event honouring late fisheries expert B. Madhusoodana Kurup, who pioneered research on the ecological degradation of the Vembanad-Kole wetlands and proposed revival strategies. This highlights the intersection of scientific research, governance, and conservation policy in addressing India’s wetland crisis.

Background

• The Vembanad-Kole wetland system, spanning Kerala’s Alappuzha, Kottayam, and Ernakulam districts, is one of India’s largest Ramsar sites (designated in 2002) and a critical component of the Southwest Coast’s biodiversity.
• Historically, the system covered approximately 40,000 sq. km but has since shrunk to around 10,000 sq. km due to land reclamation, urbanisation, and agricultural expansion, particularly for rice cultivation in Kole lands.
• The wetlands provide essential ecosystem services, including flood mitigation, groundwater recharge, carbon sequestration, and livelihood support for over 1.6 million people dependent on fisheries, agriculture, and tourism.
• Anthropogenic pressures such as pollution from domestic and industrial effluents, encroachment for infrastructure projects, and unsustainable fishing practices have degraded water quality and biodiversity.
• Climate change exacerbates these challenges through sea-level rise, altered monsoon patterns, and increased frequency of extreme weather events, threatening the hydrological balance of the system.
• The Wetlands (Conservation and Management) Rules, 2017, and the Kerala State Wetland Authority were established to regulate activities and promote conservation, but implementation gaps persist.

What is the Vembanad-Kole Wetland System?

• The Vembanad-Kole wetland system is a complex of lagoons, lakes, marshes, and rice fields (Kole lands) interconnected by a network of canals and rivers, primarily the Vembanad Lake and the Kole fields.
• It is a Ramsar site under the Ramsar Convention (2002), recognised for its international significance in biodiversity conservation, particularly as a habitat for migratory birds, fish species, and mangroves.
• The Kole lands, a traditional agro-ecosystem, are seasonally flooded rice fields that double as wetland habitats during the monsoon, supporting high agricultural productivity and biodiversity.
• The system plays a pivotal role in Kerala’s socio-economic fabric, contributing to fisheries (e.g., pearl spot, prawns), agriculture (rice, coconut), and tourism (houseboat cruises, backwaters).
• Ecologically, it acts as a natural sponge, absorbing excess water during floods and recharging groundwater, while its mangroves and aquatic vegetation sequester carbon, mitigating climate change impacts.
• The wetlands are also culturally significant, featuring in Kerala’s folklore, art, and traditional knowledge systems related to water management and agriculture.
• The system is governed by multiple legal frameworks, including the Wetland (Conservation and Management) Rules, 2017, the Environment Protection Act, 1986, and the Kerala State Wetland Authority’s guidelines.
• Research by institutions like the Kerala University of Fisheries and Ocean Studies (KUFOS) and the Cochin University of Science and Technology (CUSAT) has documented the system’s ecological decline and proposed revival strategies.
