The problem of Marine Pollution
By PIB Delhi
The Governments of India, Singapore, and Australia jointly organized an online EAS Marine Plastic Debris workshop on 14th and 15th February 2022. About 100 participants from thirteen countries participated in the workshop and deliberated on four different themes:
- The magnitude of the marine litter problem: monitoring programs and research on plastic debris in the Indo-Pacific Region.
- Best practices, novel approaches, and solutions to prevent plastic pollution.
- Polymers and plastics: technology and innovations.
- Opportunities for regional collaboration to remediate or stop plastic pollution.
Marine Litter is monitored in coastal water, sediment, beach, and biota and analyzed for micro/ meso/ macro plastics pollution. An increase in the abundance of microplastics was observed along the east coast during the monsoon, with relatively higher concentrations at the river mouth. Urban beaches have higher accumulation rates than rural beaches. Under the pan India coastal monitoring, beach clean-up activities at regular intervals to assess the marine litter from 2018 to 2022, it was found that the majority of the waste with more than 50% composition was contributed by Single-Use Plastics (SUPs).
The Ministry of Earth Sciences, through its attached office National Centre for Coastal Research (NCCR) has initiated monitoring of the temporal and spatial distribution of marine litter and plastic debris along the Indian coasts and adjacent seas. The research so far indicates that plastic debris is spread along the entire water column and sediment and high quantities are noticed during monsoon due to its spread into coastal water through creeks/rivers/estuaries by rainwater.
Low-cost floating debris traps at small river mouths, creeks, and canals to prevent the inflow of plastic to the sea were installed and trapping floating debris in the harbour and port areas can be deployed to trap the floating plastics and debris.
The participants agreed that litter pollution is transboundary, and collaborative action plans are important for combating this menace. The following suggestions were given:
- Ban on single-use plastic, behavioural changes in plastic use
- Technology can track or stop plastic from entering our oceans
- Initiate activities at a local level, regional level, national and international level.
- Local placed-based solutions to tackle the issues
- Responsibility needs to extend high up in the supply chain and change in behaviour to the plastic used in packaging by brands/producers.
- Strengthening baseline information through monitoring programs and research to inform policymakers
- Sharing of plastic monitoring data which helps to build a dataset to countermeasure and reduce ocean plastics
- Identify and develop technologies for eco-friendly alternatives to plastic
- Enforcement of policy and regulation
- Enhancement of waste management system.
- Enhancing the dialogue between countries
- Technology that innovates the repurposing, recycling, and reuse of plastic waste Citizen science, education, community program, and outreach
This information was given by the Minister of State (I/C) for M/o Earth Sciences and M/o Science & Technology, Dr. Jitendra Singh, in a written reply in Rajya Sabha today.
