Great Nicobar Project: Strategic Port, Galathea Bay Ecology & Tribal Rights Explained

The project: Officially titled the "Holistic Development of Great Nicobar Island," it is a mega infrastructure programme estimated at around Rs 81,000 crore, conceived by NITI Aayog and being implemented by the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO). It covers a total project area of about 166 sq km at the southern end of Great Nicobar Island and is to be developed in phases over roughly three decades.

The four components: The project has four major elements — (i) an International Container Transshipment Port (ICTP) at Galathea Bay; (ii) a Greenfield International Airport with dual civil-military use (a joint-user airfield and Naval Air Station); (iii) a township to house workers and settlers; and (iv) a gas- and solar-based power plant to supply electricity to the new infrastructure.

The scale: The project involves the diversion of about 130 sq km of forest (roughly 15% of the island's land area) and the felling of nearly one million trees (the government's environmental assessment cited around 9.64 lakh trees, though critics fear the actual number could be higher). The island's population is projected to rise from about 8,000 today to several lakh over the coming decades.

Geographic position: Great Nicobar is the southernmost island of the Andaman and Nicobar archipelago in the Bay of Bengal / Andaman Sea. Its southern tip, Indira Point, is the southernmost point of India. The island lies close to the Six Degree Channel — a vital shipping lane separating Great Nicobar from Indonesia's Sumatra — and is only a short distance from the Strait of Malacca, one of the world's busiest and most strategic maritime chokepoints.

Why this matters: The Strait of Malacca carries a very large share of global trade and energy shipments, including most of China's energy imports. A strong Indian presence near these Sea Lanes of Communication (SLOCs) gives India the ability to monitor and, if needed, influence movement through the chokepoint. The Andaman and Nicobar Command (ANC) — India's only joint tri-services theatre command — is based in these islands, making them central to India's Indo-Pacific and Indian Ocean Region (IOR) strategy.

Maritime focal point: Government sources have argued that the project will serve India's strategic interests and emerge as a maritime focal point because of its proximity to international shipping routes and the SLOCs. The joint-user airfield and Naval Air Station, they say, would enhance India's ability to sustain a forward presence, move military assets, monitor sea lanes, respond to crises and maintain logistics — capabilities that, they argue, cannot be provided by other existing bases even within the Andaman and Nicobar Islands.

Dual-use design: The government's position is that the project is "dual-use by design" — combining civilian and military functions — and not a commercial venture disguised as strategy. It cites the established model among maritime nations of a deep-water port providing naval logistics support, arguing that the strategic value lies precisely in the civil-military integration that a standalone military airfield could not replicate.

Transshipment explained: A transshipment port is a hub where cargo is transferred from large "mother" ships to smaller "feeder" vessels (and vice versa) for onward distribution. Large container ships that cannot call at every port instead unload at a central deep-water hub, from where smaller ships carry the cargo to final destinations.

India's current dependence: At present, a large share of India's transshipment cargo is handled at foreign ports such as Colombo (Sri Lanka), Singapore and Port Klang (Malaysia), because India lacked a deep-water transshipment hub of its own. This means lost revenue, foreign-exchange outflow and dependence on other countries' infrastructure. Vizhinjam in Kerala has recently become India's first major domestic transshipment port; the government argues that Galathea Bay, with its natural deep waters and location astride east-west shipping routes, would further reduce this dependence and strengthen India's position as a maritime logistics hub.

The clarification in the news: INS Baaz is the Indian Navy's air station at Campbell Bay on Great Nicobar, commissioned in 2012, overlooking the Six Degree Channel. Its runway was recently expanded to about 4,500 feet. Government sources have clarified that this runway will not be extended to the originally envisaged 10,000 feet, because doing so would require significant land reclamation and would itself affect tribal areas, flora and fauna.

The government's argument: Sources have pushed back on the suggestion — made by some critics — that India's strategic objectives can be met simply by expanding existing defence assets like INS Baaz. They contend this reflects an incomplete understanding of the project and of the nature of maritime power, since a comprehensive civil-military hub (combining a transshipment port, a dual-use airfield and supporting infrastructure) delivers capabilities that a runway extension alone cannot.

Forest and biodiversity loss: The diversion of around 130 sq km of pristine tropical rainforest and the felling of close to a million trees is the central ecological objection. Great Nicobar is part of the Great Nicobar Biosphere Reserve, recognised under the UNESCO Man and the Biosphere Programme (2013), and hosts two national parks (Campbell Bay and Galathea National Park). It is a recognised biodiversity hotspot with endemic species.

The leatherback turtle and Galathea Bay: Galathea Bay is one of the most important nesting sites in India for the Giant Leatherback Turtle, the world's largest sea turtle. The Galathea Bay Wildlife Sanctuary — a turtle reserve since 1997 — was denotified in 2021 to make way for the port, a move that drew strong criticism. Other threatened species in the area include the endemic Nicobar megapode (a mound-building bird) and the Nicobar long-tailed macaque, along with fragile coral reefs and mangroves vulnerable to dredging and sedimentation.

Coastal regulation concerns: Much of the project coastline falls under the most ecologically sensitive Coastal Regulation Zone category (CRZ-IA / Island CRZ-IA), where port construction is ordinarily restricted. Critics argue the project advanced through a series of regulatory relaxations and denotifications. Mitigation measures — including new sanctuaries on neighbouring islands such as Little Nicobar, Menchal and Meroe, and compensatory afforestation — have been questioned by experts, who argue that the island's unique biodiversity cannot simply be relocated or recreated elsewhere.

The Shompen: The Shompen are a semi-nomadic hunter-gatherer community of around a few hundred people, classified as a Particularly Vulnerable Tribal Group (PVTG). They live in the island's interior forests with minimal contact with the outside world, which makes them highly vulnerable to diseases and to the disruption that a large influx of outside population could bring.

The Nicobarese: The Nicobarese live mainly in settlements around Campbell Bay. Many were displaced by the 2004 Indian Ocean tsunami and have a long-standing, unresolved demand to return to their pre-tsunami villages. Critics allege that the project risks dispossessing them of ancestral land and that the Forest Rights Act, 2006 — which protects forest-dwelling communities' rights — has not been adequately honoured. There have also been concerns about the process by which the tribal council's consent for denotification of tribal reserves was obtained.

Clearance process: The project was conceived by NITI Aayog (around 2021) and received environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEF&CC) in 2022, after appraisal by the Expert Appraisal Committee (EAC). The EAC itself had noted that site selection prioritised technical and financial considerations, with limited weight to environmental factors.

The NGT's role: The National Green Tribunal (NGT), which hears environmental disputes, constituted a High-Powered Committee to review the clearances. The NGT has since upheld the environmental clearance, holding that there were adequate safeguards and no good ground to interfere, while also recognising the project's strategic importance. The matter has thus been examined by the country's specialised environmental court, even as conservationists continue to raise concerns.

The government's case: Supporters frame the project as essential for national security and maritime power in the Indo-Pacific, for cutting India's dependence on foreign transshipment ports, and for the broader goals of the Maritime India Vision and the blue economy. They stress that the project is dual-use and that environmental and tribal safeguards have been built in and judicially examined.

The critics' case: Opponents — including environmentalists and opposition leaders — argue that the ecological and human costs are irreversible: loss of rainforest and turtle habitat, threats to PVTGs, and the denotification of protected areas. Some have alleged that the strategic justification is being used to push what is essentially a commercial project, and that approvals rested on weak grounds. The government has rejected these characterisations, maintaining that the project is strategically driven by design. (These are competing claims in a contested public debate; the points are presented here as positions, not as established conclusions.)

The Great Nicobar debate captures one of the hardest trade-offs in development policy — between genuine strategic and economic imperatives in a contested maritime region, and the irreversible loss of a fragile, biodiverse ecosystem and the rights of some of the world's most vulnerable indigenous communities. A balanced path forward would involve transparent, science-led environmental monitoring by independent institutions; strict, enforceable safeguards for the Shompen and Nicobarese, with genuine free, prior and informed consent under the Forest Rights Act; phased construction that minimises land reclamation and forest loss; and credible, verifiable mitigation rather than nominal compensatory measures. Where strategic needs and ecological protection genuinely conflict, the goal should be to secure India's maritime interests in the least ecologically damaging way possible, with continuous judicial and parliamentary oversight to ensure that "strategic necessity" is not used to bypass environmental and tribal protections.
