Examine the ecological and governance challenges associated with deep-sea mining in the context of India's ISA exploration contracts.

The International Seabed Authority (ISA) regulates "the Area" — seabed beyond national jurisdiction — as the common heritage of mankind under UNCLOS. India, now the first country holding two ISA contracts for polymetallic sulphides [1], is advancing faster in deep-sea capability than the ecological science and the rulebook that must govern it.

Ecological challenges

• Irreversible physical damage: a 1979 test-mining track in the Pacific was still visible in 2023 — 44 years later — with several faunal groups only beginning to re-establish amid persistent seafloor change [2].
• Plume dispersal: mining stirs fine sediment that may disperse for hundreds of kilometres and take long to resettle, harming filter-feeders far outside the licence block [3].
• Habitat loss: nodules are the only hard substrate for corals and sponges on the abyssal plain; their removal eliminates the habitat itself [3].
• Knowledge deficit: baseline biodiversity surveys of seamounts under the Deep Ocean Mission (MoES, Rs 4,077 crore, 2021–26) [4] measure what exists — they cannot guarantee restoration.

Governance challenges

• Regulatory vacuum: the ISA's Mining Code for exploitation remains unadopted; negotiations on the Revised Consolidated Text (regulations 1–107) continued through the 30th session without agreement [5].
• Unsettled core issues: payment regimes, environmental thresholds and enforcement at 5,000 m depth are still open [5].
• Contested legitimacy: IUCN and many states seek a moratorium until impacts are understood [3]; India has articulated no public position.
• Timing mismatch: India's polymetallic nodules contract runs only to 2027 [6], so the exploration-to-exploitation decision may arrive before global rules exist.

Exploration and indigenous ocean technology are defensible national goals; commercial extraction is not, until evidence and regulation catch up. India should publicly decouple exploration from exploitation, design low-contact collectors, and demarcate no-touch conservation zones within its contract areas — converting itself from a quiet contractor into a rule-maker consistent with the common-heritage principle.
