Tamil Nadu is endowed with three blue carbon ecosystems namely mangroves, salt marshes and seagrass meadows. They play a crucial role in carbon storage and sequestration, biodiversity support, and livelihood provision for local communities. The Tamil Nadu State Wetland Authority (TNSWA) and Suganthi Devadason Marine Research Institute (SDMRI) conducted a study to estimate the blue carbon stocks in the top one metre of the soil of representative sites of mangrove, salt marsh and seagrass ecosystems in Tamil Nadu. This study provided firsthand information on the rich blue carbon wealth of the State hidden in the soil/sediment. The data was systematically compiled, documented and published as a Technical Report namely “Blue Carbon Wealth of Tamil Nadu, India: The Role of Coastal Ecosystems as Carbon Sinks” and the report was brought out by Environment, Climate Change and Forests Department of Government of Tamil Nadu in partnership with SDMRI, Tuticorin.
