ClearEnvironmental Jeopardy and Coping Strategies of the Small-Scale Fishers in the Bangladesh Sundarbans: The Precedent of the World’s Largest Mangrove
Researchers studied the environmental risks and coping strategies of small-scale fishers in six villages of the Bangladesh Sundarbans, the world's largest mangrove forest. They found that fishers face escalating threats from climate change impacts, cyclones, and environmental pollution, but have developed various adaptive strategies. The study highlights the vulnerability of communities whose livelihoods depend directly on ecosystems increasingly affected by environmental degradation.
Aquatic Pollution in the Bay of Bengal: Impacts on Fisheries and Ecosystems
This review examines the sources and impacts of aquatic pollution in the Bay of Bengal, including heavy metals, pesticides, petroleum compounds, and microplastics. Researchers found that rivers transport these pollutants from inland areas to the bay, where they accumulate in fish and other marine life, posing threats to food safety through bioaccumulation. The study calls for stronger pollution controls, real-time water monitoring, and sustainable practices to protect both the ecosystem and the communities that depend on it.

Seasonal bias and overlooked climate impacts in mangrove ichthyoplankton research: emerging threats and knowledge gaps
This review of 80 studies found that scientists have mostly ignored how extreme weather events affect baby fish in mangrove forests, even though these coastal ecosystems serve as crucial nurseries where fish grow up. The few studies that did look at climate impacts suggest that hurricanes, heat waves, and other extreme events damage mangrove habitats and hurt fish populations that people depend on for food. The researchers say we urgently need more long-term studies to understand these threats, since healthy mangroves are essential for supporting fisheries that feed coastal communities.

Researchers monitored water quality in tidal creeks of India's Sundarbans mangrove region for a full year, finding that salinity, turbidity, and dissolved oxygen varied most dramatically across seasons and were heavily influenced by monsoon runoff and boat traffic. The baseline data provides a foundation for managing water quality in this ecologically sensitive and biologically rich estuary.
Impact of elevated environmental pollutants on carbon storage in mangrove wetlands: A comprehensive review
Researchers synthesized global studies on pollutant impacts in mangrove wetlands — which store about 10% of coastal ocean carbon — finding that microplastics reduce carbon stocks by 1-12% by impairing photosynthesis and destabilizing sediments, while heavy metals and oil spills compound the damage to these critical climate carbon sinks.
Unveiling the impact of anthropogenic wastes on greenhouse gas emissions from the enigmatic mangroves of Indian Sundarban
Researchers developed a dynamic model to simulate greenhouse gas emissions (CO2, CH4, N2O) from Indian Sundarban mangroves under the influence of anthropogenic waste inputs including heavy metals and microplastics. Both heavy metals and microplastics were identified as significant drivers of elevated GHG emissions from mangrove soils, with CO2 being most sensitive to microplastic impact on microbial respiration.
Unveiling the microplastic crisis: Insights into Bangladesh's aquatic ecosystems - origins, impact, and solutions
This review examines the growing microplastic crisis in Bangladesh's rivers, estuaries, and coastal waters, finding that the country's rapid urbanization and limited waste management have led to widespread contamination. Microplastics were documented in water, sediment, and fish across multiple Bangladeshi water systems. Since over 160 million people in Bangladesh depend on these water resources for drinking, farming, and fishing, the contamination poses a significant public health concern.
