From pollution to finance: Linking marine pollution pathways and blue finance for coastal resilience in South Asia
AI summary Read the abstract
This review paper summarizes existing research on pollution, including microplastics, in South Asia's coastal waters. It describes how poor infrastructure and institutional gaps worsen pollution, and proposes combining pollution monitoring with funding tools like blue bonds to support coastal management.
South Asia's marine and coastal environments face escalating pressures from industrialization, urbanisation, and climate variability, yet policy responses remain fragmented and underfunded. This review synthesises sources, pathways, and impacts of marine pollution and advances a framework that integrates scientific assessment with blue finance mechanisms tailored to the region's socio-ecological realities. It considers both legacy contaminants (heavy metals, hydrocarbons, nutrients) and emerging threats (microplastics, pharmaceuticals, nanomaterials), linking them to governance and financial readiness. The review highlights how monsoonal hydrology, inadequate infrastructure, and institutional fragmentation intensify pollutant accumulation and economic vulnerability. It further examines state-of-the-art monitoring technologies, nature-based solutions, and persistent policy gaps. The paper's central contribution is a finance-ready pathway coupling scientific indicators with governance reforms and instruments such as blue bonds, trust funds, and risk-sharing facilities. By embedding pollution management in a blue economy framework, this study informs strategies for coastal resilience and sustainable ocean-based livelihoods.

Microplastics in Indian Coastal Ecosystems: Sources, Distribution, and Ecological Impact
AI summary Read the abstract
This review pulls together a decade of research on tiny plastic particles polluting India's 7,500 km coastline, finding that microplastics are widespread in beaches, water, and sea life, with pollution levels tracking closely with nearby cities, rivers, and fishing activity. Since fish and shellfish are shown to ingest these particles, this raises real concerns for the seafood many coastal communities depend on for food and income. The paper doesn't test new samples itself, but instead synthesizes existing science to highlight where research and policy need to focus next.
