India’s marine litter problem

In News

According to the Central Pollution Control Board, India generates 55 million tonnes of municipal waste annually, of which only 37 per cent is treated.

Reasons 

  • Growing population, rapid urbanisation, shifting consumption patterns and changing lifestyles have resulted in the mismanagement of plastic waste, leading to the accumulation of municipal solid waste.
  • Most of these items, especially plastic items, contribute significantly to the growing burden of marine debris. 
  • Land-based sources account for most of the plastic in the water.
  • Unaccounted waste from urban agglomerations is carried by river systems to oceans for final dumping
  • Mismanagement of plastic waste generated in coastal cities and urban centres are leading to this reaching the water bodies

Do you Know?

  • India has a coastline spanning 7,517 kilometres. It is spread across eight states and borders a 2.02 million square kilometre of Exclusive Economic Zone (EEZ).
  • India’s eight coastal states house a population of 420 million. Of this, about 330 million live on or within 150 km of a coast. 
  • Coastal districts are home to nearly 14.2 per cent of the country’s total population. 
    • Around 95 per cent of India’s trade by volume and 68 per cent by value is executed through waterways.
  • India’s coastline contributes to its ecological richness, biodiversity and economy.

Concerns and Challenges 

  • Every year, thousands of tonnes of garbage, composed of plastics, glass, metals, sanitary products, clothes, etc., are dumped into the country’s coastline.
  •  However, plastics contribute a major portion of about 60 per cent of the total marine debris that reaches the oceans.
  • Marine litter is spread along the entire water column. High quantities of sediments are noticed during monsoon due to their spread into coastal water through creeks/rivers/estuaries, the research indicated.
  • Marine litter threatens ecosystems and adversely affects fishery and tourism industries around the globe. 
  • In addition to negative economic impact, it affects public health with increased concerns about micro-plastic and risk of particles entering the food chain
  • It tricks wildlife: Animals can easily get trapped in plastic bags or discarded fishing gear, or they mistake plastic for their food and it enters the food chain.

Initiatives

  • The Ministry of Earth Sciences, through its attached office National Centre for Coastal Research (NCCR), has undertaken beach clean-up initiatives, awareness programmes and beach litter quantification studies at regular intervals.
  • Attempts made by some organisations in rescuing marine species from the debris are worth mentioning. TREE Foundation, a Chennai-based non-profit, has been incessantly working on this.
  • India and Germany signed an agreement on ‘Cities combating plastic entering the marine environment’
  • The UK-India Intervention: The Prime Ministers of the United Kingdom and India agreed a ‘Roadmap 2030’, which sets out an ambitious framework for UK and India partnerships in a wide range of science disciplines, including marine science. 

Suggestions for managing marine litter in a better way.

  • The National Marine litter Policy of India, announced in 2018, should be formulated.
  • Marine litter and microplastics distribution and characterisation study should be conducted across the Indian coast.
  • A forum of coastal cities should be created for ensuring a cross-learning ecosystem and to build a synergetic association of urban local bodies and local administration located on the coast.
  • A long-term vision plan should be developed for promoting partnerships among coastal towns, cities and urban administration for the reduction of marine litter and the creation of sustainable waste management ecosystems.
  • Regular beach clean-up and awareness programmes should be conducted instead of annual ones.
