Marine Pollution and Sustainable Blue Economy in the Bay of Bengal: Challenges and Opportunities for Bangladesh
Summary
This review assessed marine pollution in the Bay of Bengal affecting Bangladesh's blue economy, identifying plastic and microplastic pollution from land-based runoff, fishing activities, and shipbreaking as major threats to fisheries and sustainable marine resource use.
The Bay of Bengal (BoB) is a vital natural resource supporting the blue economy of Bangladesh, embracing fisheries, terminals, shipbuilding /shipbreaking, sea tourism and ecosystem services. Nevertheless, marine pollution is on the rise from land- and sea-based sources in the region. The objective of this paper is to synthesize recent research about the major vectors that deliver pollution to oceans and create deteriorating conditions for marine life including some commercial fishing operators as well as any proven beneficial ocean fertilization including key vectors plastics and microplastics, oil and chemical contaminants, nutrient loadings and heavy metals. It evaluates environmental and socio-economic consequences, governance instruments constraints or opportunities for pollution mitigation pathways to directly address sustainable blue growth. These include case studies of shipbreaking and the toxic legacies thereof in Chattogram, mangrove restoration in the Sundarbans as a nature-based adaptive response, and district-level plastic leakage and circular economy interventions. Finally, the paper provides policy recommendations in respect of land-sea integration governance, financial mechanisms, technology and capacity building, community inclusivity strategies to conserve Bangladesh coastal and marine environment for the benefit of future generations.

Occurrences, sources, fate and impacts of plastic on aquatic organisms and human health in global perspectives: What Bangladesh can do in future?
This review provides a comprehensive overview of plastic and microplastic pollution in aquatic environments globally, with a specific focus on the situation in Bangladesh. Researchers compiled evidence on the sources, fate, and biological impacts of plastic pollution on aquatic organisms ranging from plankton to fish, as well as potential human health risks. The study concludes with recommendations for waste management strategies and future research priorities tailored to Bangladesh's specific environmental and economic challenges.
