Discuss the sources, impacts and control measures of Marine pollution.

In short

Marine pollution comes from plastics, industrial effluents carrying mercury and pesticides, sewage and oil spills, causing coral bleaching, dead zones and falling fish stocks that threaten fisherfolk on coasts like Andhra Pradesh's 974 km shoreline. It is controlled through CRZ Notifications, MARPOL, the 2022 single-use plastic ban and coastal monitoring.

Introduction
Marine pollution is a critical threat to India’s extensive coastline, with Andhra Pradesh’s 974 km coastline facing severe risks from plastic, chemical, and oil pollutants affecting biodiversity and livelihoods.
Institutional Framework and Policies
•

Regulatory Instruments

Coastal Regulation Zone (CRZ) Notifications under the Environment Protection Act, 1986, regulate coastal activities; India adheres to MARPOL and UNCLOS, empowering coastal pollution control in Andhra Pradesh’s coastal districts.

•

National Campaigns

The 2022 Single-Use Plastic Ban and UNEP’s Clean Seas Campaign target plastic reduction, with implementation efforts in Andhra Pradesh’s coastal towns.

Challenges and Impacts
•

Plastic and Microplastic Pollution

Studies record rising plastic discharge along the Chennai coast, signaling similar threats to Andhra Pradesh’s ports and fisheries; microplastics contaminate seafood, posing health risks.

•

Governance Gaps

Weak enforcement of CRZ and plastic bans, limited technology, and financial constraints hamper pollution control in Andhra Pradesh’s coastal zones.

•

Ecological Consequences

Pollution causes coral bleaching, fish stock decline, and dead zones, threatening livelihoods of over four million fisherfolk nationally, including Andhra Pradesh’s coastal communities.

Way Forward
•

Enhanced Monitoring

Expand networks like COMAPS along Andhra Pradesh’s coast for real-time pollution data.

•

Waste Management and Awareness

Scale up plastic recycling and community campaigns in Andhra Pradesh.

•

Institutional Strengthening

Create a coastal pollution task force in Andhra Pradesh for enforcement of CRZ and plastic bans.

•

Sustainable Blue Economy

Promote eco-friendly aquaculture and green maritime transport1 in Visakhapatnam and other ports.

Conclusion
Addressing marine pollution through integrated policies, scientific monitoring, and community engagement is essential to safeguard Andhra Pradesh’s marine biodiversity and blue economy.
