What Happened
- A recent editorial has highlighted that the ₹81,000 crore Great Nicobar mega-infrastructure project requires broader consensus — among environmental experts, tribal rights groups, and strategic planners — to fully leverage the island's potential without irreversible ecological damage.
- The National Green Tribunal (NGT) cleared the project citing its strategic importance and asserting that adequate environmental safeguards are in place, but environmentalists and researchers continue to raise concerns about biodiversity loss, tribal displacement, and disaster risk.
- The project involves building an international container transshipment terminal, a dual-use civil-military airport, a power plant, and a township — a comprehensive transformation of one of India's most ecologically sensitive and strategically significant islands.
- Environmental concerns centre on the felling of approximately 964,000 trees, destruction of Galathea Bay (a critical nesting site for the endangered Leatherback Sea Turtle), and threat to the Nicobar Megapode — a bird species found nowhere else on Earth.
- The project also raises serious concerns about the impact on the Shompen — a Particularly Vulnerable Tribal Group (PVTG) — who may be exposed to infectious diseases from large-scale in-migration of workers and settlers.

Great Nicobar Island — Geography and Strategic Location
Great Nicobar is the largest and southernmost island of the Nicobar Island group, which forms the southern cluster of the Andaman and Nicobar archipelago. Its location makes it one of India's most strategically valuable pieces of territory.
- Location: Southernmost tip of India (Indira Point, 6°45'N, 93°49'E); Mount Thullier (642 m) is a major peak
- Proximity to shipping lanes: Sits near the Strait of Malacca — one of the world's busiest shipping lanes, through which approximately one-third of global sea trade passes
- Distance from key chokepoints: Close to Sunda Strait, Lombok Strait, and Indonesia; shares maritime borders with Indonesia (~165 km south) and is 280 km from Myanmar
- Ten Degree Channel: Separates the Nicobar group from the Andaman group; strategically important for naval monitoring
- Defence significance: Provides India a maritime domain awareness (MDA) advantage in the Eastern Indian Ocean; enables monitoring of Chinese naval movements through the Strait of Malacca
- Proximity to China: The Coco Islands (Chinese-leased from Myanmar, ~750 km north) and India's Nicobar bases are in close strategic proximity
Connection to this news: The island's geographic position — astride the Malacca approach and flanking both the Bay of Bengal and the eastern Indian Ocean — gives a transshipment terminal and military airport here outsized strategic value for India's Indo-Pacific posture.
Environmental Concerns — Biodiversity and Ecological Sensitivity
Great Nicobar Island is classified as a biodiversity hotspot with unique flora and fauna found nowhere else. The scale of forest diversion required for the project has alarmed ecologists and conservation biologists.
- Tree felling: ~964,000 trees estimated to be affected according to MoEF&CC parliamentary response
- Galathea Bay: Critical nesting beach for the Leatherback Sea Turtle (Dermochelys coriacea) — the world's largest sea turtle, classified as Vulnerable on the IUCN Red List; the bay is also a wildlife sanctuary
- Nicobar Megapode (Megapodius nicobariensis): An endemic ground-nesting bird found only in the Nicobar Islands, classified as Vulnerable; mound nesting makes it particularly sensitive to land use change
- Coral reefs and marine biodiversity: The island's coastal waters host extensive coral reef systems that would be impacted by port construction and dredging
- Seismic risk: Great Nicobar lies directly on the Sunda megathrust fault — the same fault that triggered the catastrophic Indian Ocean tsunami in December 2004 (9.1 magnitude earthquake)
Connection to this news: The tension between the ecological value of Great Nicobar — which serves as a reference ecosystem for the entire Indo-Pacific biogeographic region — and the strategic and economic rationale for the project is at the heart of the governance debate the editorial engages with.
Tribal Rights and Particularly Vulnerable Tribal Groups (PVTGs)
The Shompen are one of India's 75 designated Particularly Vulnerable Tribal Groups (PVTGs) — communities that are pre-agricultural, have a declining or stagnant population, very low literacy, and live in remote, geographically isolated areas.
- PVTGs: Identified by the Dhebar Commission (1973) and further studied by the Shilu Ao Committee; currently 75 PVTGs across 18 states and 1 UT
- Forest Rights Act, 2006: Recognises individual and community forest rights of scheduled tribes and other traditional forest dwellers; PVTG rights require special sensitivity
- Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act: Consent of Gram Sabha is required before diversion of forest land on which tribal communities have rights
- Disease vulnerability: Isolated tribal groups like the Shompen have no immunity to common pathogens; large-scale in-migration of construction workers poses existential biosecurity risks (analogous to impact of contact on Sentinelese/Jarawa in Andaman Islands)
- Constitutional protection: Fifth Schedule (for most tribal areas) and Article 244 protect tribal rights; Andaman & Nicobar comes under Union Territory administration with special provisions
Connection to this news: The Shompen's survival as a people — not just their way of life — depends on maintaining their isolation. Large-scale construction and worker in-migration for a ₹81,000 crore project could be an irreversible threat to this community, making the tribal consent and protection framework a critical governance issue.
