Why in the news

The BBNJ Treaty, meant to govern the high seas, is still short of the ratifications needed to take effect, and India has not yet ratified it.

About the treaty

  • Third implementing agreement under UNCLOS.
  • Protects marine biodiversity in areas beyond national jurisdiction.
  • Aims: conserve high seas biodiversity; share benefits of marine genetic resources fairly; require environmental impact assessments for activities in international waters.
  • Applies beyond 200 nautical miles from national EEZs, roughly 64% of ocean area.
  • India: signed, not ratified.

Why it is needed

  • Protection gap: just 1.44% of high seas protected.
  • Deep-sea mining, overfishing and marine pollution lack international rules.
  • Growing biotech use of marine genetic resources needs governance.
  • Equity: stops developed countries dominating ocean wealth.
