Capitalizing on the global financial interest in blue carbon
This study characterized the rapid rise in financial interest in blue carbon ecosystems like mangroves and seagrasses, analyzing the investment landscape and identifying key challenges that must be addressed to scale carbon credit markets for coastal ecosystem conservation.
Microplastics pollution load in Sundarban delta of Bay of Bengal
Researchers reviewed microplastic pollution in the Sundarban Delta of the Bay of Bengal, finding that approximately 4 million tonnes of microplastics are discharged annually into the region from rivers in India and Bangladesh. The study documented plastic accumulation in sediments, water, and aquatic organisms, with over 56 tons of plastic waste deposited after a single cyclone in 2020. The findings highlight the urgent need for stronger policy measures to protect the world's largest mangrove ecosystem from microplastic contamination.
Mangrove Health: A Review of Functions, Threats, and Challenges Associated with Mangrove Management Practices
This review describes how mangrove forests protect coastlines, store carbon, and support marine life, but are under increasing threat from development, pollution, and climate change. Mangrove loss matters for microplastic pollution because these ecosystems act as natural filters that can trap plastic particles before they spread further into the ocean and food chain.
