India's Deep Ocean Mission positions the country as a serious contender in seabed resource exploration, with polymetallic nodules in the Central Indian Ocean Basin representing a strategic reserve of critical minerals essential for clean energy transitions.
Polymetallic nodules are potato-shaped accretions found on the deep ocean floor, containing economically significant concentrations of manganese, nickel, cobalt, and copper. These minerals are critical inputs for battery technology, electric vehicles, and renewable energy infrastructure, making their extraction strategically important for India's industrial and energy goals.
The International Seabed Authority (ISA) has allocated approximately 1.5 lakh square kilometres in the Central Indian Ocean Basin to India for exclusive exploration. This allocation grants India pioneer investor status, enabling systematic survey, sampling, and eventual extraction planning under ISA's regulatory framework.
The Deep Ocean Mission, approved by the Union Cabinet, provides an integrated framework covering deep-sea mining technology, underwater vehicles, ocean climate change advisory services, and biodiversity conservation. It aims to develop indigenous technological capability rather than dependence on foreign deep-sea mining consortia.
Deep-sea mining raises significant concerns regarding disruption of fragile benthic ecosystems, sediment plumes, and irreversible biodiversity loss. Balancing resource extraction with environmental stewardship under ISA's evolving Mining Code remains a critical governance challenge for India's ocean policy.
India's polymetallic nodule programme sits at the intersection of critical mineral security, technological self-reliance, and environmental responsibility. Sustainable deep-sea governance frameworks must evolve alongside extraction capabilities to ensure long-term strategic and ecological balance.
