Tamil Nadu Wetland Mission

Wetlands offer a multitude of ecosystem services which have significant impact on the socio-economic sphere of our lives. Millions of people depend on wetlands for their livelihood.

They play a critical role in water purification, ground water replenishment, drought and flood management. Conservation of wetlands is essential for water and food security. Role of wetlands has become even more important in the light of adverse and serious impact of climate change. Wetlands are particularly impacted by climate change, especially sea-level rise, coral bleaching as a result of increased sea surface temperatures, and changing hydrology in inland waters. Wetlands are known to be repositories of carbon and are considered as "carbon sinks".


Minimize the rate of loss of natural wetlands and feasibly enforce "Net Zero Wetland Degradation" with the help of Government, Experts, NGO's and local communities or the wetland mitras.

Improvement in water-related ecosystem services, such as clean drinking water, water for agriculture and flood regulation, erosion control, sediment deposition, carbon sequestration, increase in agricultural production, inland fisheries and tourism activities.

Reduction in incidences of nutrient enrichment from current level of 100% to 25% by promoting organic farming adjoining the wetlands by the end of 5 years

Introduction of Carbon Credit System in the wetlands restoration programme and involve local communities for reaping the benefits of future voluntary Carbon market.

Generate widespread awareness amongst the people and communities on the ecosystem value of the wetlands and the need for its conservation and wise use for the sustenance of future generations.


Climate Studio

The Mission will identify and map 100 wetlands in 5 years and restore the ecological balance with focus on livelihood options

A Project Management Unit (PMU) has been set up under the Additional Principal Chief Conservator of Forests & Member Secretary, Tamil Nadu State Wetlands Authority which will be involved in the Mission activities like preparation of brief documents and final notification of the natural wetlands, preparation of proposals for the RAMSAR sites, creation of wetland conservation centre at Muthupet, Tiruvarur District etc., as envisaged under the Action Plan for the Tamil Nadu Wetland Missionfor the year 2021-2012.
