What Happened

  • The National Green Tribunal (NGT) cleared the Rs 92,000 crore Great Nicobar Island mega-infrastructure project on February 16, 2026, upholding environmental clearances granted by the Ministry of Environment, Forest and Climate Change.
  • The NGT cited the project's "strategic importance" and found no good ground to interfere, ruling that environmental safeguards and appraisal processes were adequate.
  • The project includes a deep-draft international transshipment port at Galathea Bay, a greenfield international airport, a township, tourism infrastructure, and associated road and utility networks.
  • It is to be executed in phases over 30 years and will position Great Nicobar as a key maritime and logistics hub near the Malacca Strait.
  • Petitioners had raised concerns about diversion of forest land, felling of over 8-9 lakh trees, threats to coral reefs, turtle nesting sites, and impacts on the Shompen and Nicobarese indigenous communities.
  • A separate legal challenge to forest clearances remains pending before the Calcutta High Court, with final hearing scheduled for the week beginning March 30, 2026.

Static Topic Bridges

Andaman and Nicobar Command and Maritime Security

The Andaman and Nicobar Command (ANC), India's only tri-services theatre command, was established in 2001 at Port Blair (Sri Vijaya Puram). The islands are located approximately 1,200 km from mainland India but only 160 km from Indonesia and about 100 km from the western entrance to the Malacca Strait via INS Baaz at Campbell Bay.

  • The Malacca Strait is one of the world's busiest shipping lanes, with over 94,000 merchant ships crossing the Six Degree and Ten Degree Channels annually, carrying 40% of global freight trade.
  • INS Baaz, India's southernmost naval air station at Campbell Bay in Great Nicobar, lies barely 100 km from the Malacca Strait.
  • Car Nicobar hosts an Indian Air Force facility providing air dominance over the Bay of Bengal and sustained surveillance of shipping activity.
  • The proposed deep-water port and airfield on Great Nicobar would significantly enhance the ANC's force projection capabilities in the eastern Indian Ocean.

Connection to this news: The NGT's clearance enables India to build strategic infrastructure at Great Nicobar that would strengthen the tri-services command's ability to monitor and influence one of the world's most critical maritime chokepoints, countering China's growing presence in the Indian Ocean Region.

Particularly Vulnerable Tribal Groups (PVTGs) and Tribal Rights

India recognises 75 Particularly Vulnerable Tribal Groups (PVTGs) across 18 states and one Union Territory. PVTGs are identified by the Ministry of Tribal Affairs based on criteria including pre-agricultural technology, stagnant or declining population, and low literacy levels.

  • The Shompen, a semi-nomadic hunter-gatherer community of approximately 250 individuals, have inhabited Great Nicobar's forests for over 30,000 years and largely avoid outside contact.
  • The Nicobarese, numbering approximately 1,200 on Great Nicobar, have distinct Mongoloid ancestry.
  • Both groups are classified as PVTGs and are protected under the Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956.
  • Article 342 of the Constitution empowers the President to specify Scheduled Tribes, and the Fifth and Sixth Schedules provide special protections for tribal areas.

Connection to this news: The mega-project's environmental and social impact on the Shompen and Nicobarese communities has been a central concern of petitioners, as large-scale construction and population influx could irreversibly alter the habitat and way of life of these highly vulnerable groups.

Galathea Bay: Biodiversity Hotspot and Conservation

The Andaman and Nicobar Islands are part of one of the world's 36 biodiversity hotspots. Great Nicobar alone hosts two national parks (Campbell Bay and Galathea), with over 650 plant species, 14 mammal species, 71 bird species, and numerous endemic species.

  • Galathea Bay is the most important nesting site in the northern Indian Ocean for the Leatherback sea turtle (Dermochelys coriacea), listed as Vulnerable on the IUCN Red List with a declining global population.
  • Nearly 500 Leatherback nests have been counted at Galathea Bay across recent nesting seasons.
  • The Galathea Bay Wildlife Sanctuary (designated a turtle reserve since 1997) was denotified in 2021 to make way for the port.
  • The Great Nicobar Biosphere Reserve (103,870 hectares) was designated under UNESCO's Man and Biosphere Programme in 2013.
  • The Nicobar Megapode (Megapodius nicobariensis), an endemic mound-nesting bird, and saltwater crocodiles also inhabit the area.

Connection to this news: The NGT clearance permits development in an area of extraordinary ecological value, raising questions about the adequacy of environmental impact assessments when strategic and economic imperatives override biodiversity conservation mandates.

National Green Tribunal: Powers and Jurisdiction

The NGT was established under the National Green Tribunal Act, 2010, to handle cases relating to environmental protection, conservation of forests, and other natural resources. It is a specialised body equipped with multidisciplinary expertise.

  • The NGT has original jurisdiction over all civil cases involving substantial questions relating to the environment, including enforcement of environmental laws such as the Environment Protection Act 1986, Forest Conservation Act 1980, Water Act 1974, and Air Act 1981.
  • It can grant relief in the form of compensation and restitution and has appellate jurisdiction over orders under the listed statutes.
  • NGT orders are binding and enforceable as decrees of a civil court; they can be appealed before the Supreme Court within 90 days.
  • The Tribunal applies the principles of sustainable development, precautionary principle, and polluter pays principle.

Connection to this news: The NGT's decision to uphold environmental clearances for the Great Nicobar project, despite objections about ecological damage and tribal rights, demonstrates the Tribunal's balancing act between environmental protection mandates and strategic national interests.
