🗞️ Why in News The Draft Master Plan for Great Nicobar Island Development Area–2047 was released, with tourism as the primary economic driver alongside a transshipment port, airport, and township. The project has reignited debate over the cost of strategic development: ~130 sq km of tropical rainforest will be diverted, ~58 lakh trees felled, leatherback sea turtle nesting grounds disrupted, and the indigenous Shompen — one of India’s most isolated tribal groups — potentially displaced. The National Green Tribunal cleared the project in February 2026, citing “strategic and national importance.”
Great Nicobar Island — The Basics
Great Nicobar is the southernmost island of the Andaman and Nicobar archipelago:
| Fact | Detail |
|---|---|
| Location | Southernmost tip of India’s island territory |
| Area | ~910 sq km |
| Distance from Strait of Malacca | ~90 nautical miles |
| Distance from Port Blair | ~525 km |
| Distance from Indira Point (southern tip) to Sabang, Aceh (Indonesia) | ~145 km |
| Biodiversity | Tropical rainforest; Biosphere Reserve (UNESCO, 2013 tentative list) |
| Protected status | Great Nicobar Biosphere Reserve; part notified as wildlife sanctuary |
| Indigenous population | Shompen (~400; PVTG) and Nicobarese |
The Holistic Development Project — What Is Planned
Project cost: ~₹81,000 crore | Implementing agency: Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO) | Timeline to 2047
Four Core Components
1. Transshipment Port — Galathea Bay
- Location: Galathea Bay, southern Great Nicobar
- Capacity: 16 million TEUs (twenty-foot equivalent units) when fully operational
- Context: India currently lacks a major transshipment hub — about 75% of India’s transhipment cargo is handled by Colombo (Sri Lanka), Singapore, and Klang (Malaysia)
- Strategic argument: A port at Galathea Bay would capture transshipment traffic from the Bay of Bengal + Indian Ocean routes — commercially and strategically valuable
- Naval dimension: The port is designed for dual use (commercial + strategic naval base)
2. International Airport
- Greenfield airport to handle international traffic
- Will replace current limited air connectivity via Port Blair
- Enables direct cargo + passenger flights
3. Township for ~3.5 lakh residents
- Residential, commercial, institutional zones
- To house port workers, service sector, government employees
4. Tourism and Hotels
- Tourism projected: 98,000 visitors by 2029 → 1 million by 2055
- High-end eco-tourism, beach resorts, adventure tourism
Environmental Cost — What Is Being Lost
Forest Diversion
| Impact | Figure |
|---|---|
| Total forest to be diverted | ~130 sq km (12,981 hectares) |
| Trees to be felled | ~58 lakh (5.8 million) |
| Forest type | Tropical evergreen + semi-evergreen rainforest |
| Status of diverted area | Part falls within Great Nicobar Biosphere Reserve buffer zone |
This is among the largest single-project forest diversions in India’s recent history.
Leatherback Sea Turtle — A Global Crisis
Leatherback sea turtles (Dermochelys coriacea) nest on Galathea Beach — where the port is proposed:
- Leatherbacks are the world’s largest turtle (up to 600 kg)
- IUCN: Vulnerable globally; Critically Endangered in the Pacific
- India’s WPA 1972: Schedule I (highest protection)
- Galathea Beach is one of the most significant nesting sites in the Indian Ocean
- Port construction during nesting season (November–April) would directly eliminate nesting habitat
Other Biodiversity Threats
- Nicobar Megapode (endemic, Schedule I bird) — nesting mounds in construction zone
- Saltwater crocodile (Schedule I) — rivers and mangroves in project area
- Coral reefs — Galathea Bay has live coral; dredging will cause turbidity and bleaching
- Endemic flora — approximately 25+ endemic plant species in the project area
Cumulative Environmental Impact
- The Environmental Impact Assessment (EIA) was criticised for not conducting a cumulative impact assessment across all four project components
- Seasonal construction ban (Nov–Apr for turtle nesting) was proposed but critics say it is insufficient
- River diversion for township freshwater needs will affect mangrove ecology
The Shompen — A Vulnerable Tribe at Risk
The Shompen are one of India’s 75 Particularly Vulnerable Tribal Groups (PVTGs):
| Feature | Detail |
|---|---|
| Population | ~350–400 individuals (one of India’s smallest tribal groups) |
| Location | Interior rainforests of Great Nicobar |
| Contact status | Minimal voluntary contact with outside world; semi-isolated |
| Language | Shompen language (linguistic isolate; not fully classified) |
| Livelihood | Hunter-gatherer; forest-dependent |
| Legal protection | Scheduled Tribe (Article 342); PVTGs under special government framework |
| Land rights | Forest Rights Act 2006 applies; no formal land titles held |
Core concern: The township + tourism infrastructure will bring tens of thousands of outsiders into contact with a population that has survived for millennia through isolation. Historical precedent from the Andaman Islands:
- Great Andamanese: ~8,000 in 1858 → ~57 today (destroyed by contact-induced disease and displacement)
- Onge: Dramatically reduced; confined to Little Andaman reserve
The Shompen are not “consulted” in any meaningful sense — they have no literacy in Indian languages, no legal representation, and no mechanism for Free, Prior, and Informed Consent (FPIC) as required under international standards (ILO Convention 169) and Forest Rights Act.
The Strategic Case — Why the Government Is Proceeding
Malacca Strait Chokepoint
India’s maritime vulnerability:
- ~80% of India’s energy imports transit the Strait of Malacca (or Lombok Strait) — controlled waters near Singapore/Indonesia
- In a conflict scenario, adversary naval power could choke India’s energy supply
- A transshipment port + naval base at Galathea Bay provides India with a forward position to monitor and, if necessary, interdict adversary movement through the Indian Ocean
China’s String of Pearls
China has developed or supported ports in:
- Hambantota (Sri Lanka) — 99-year lease (debt-for-equity, 2017)
- Gwadar (Pakistan) — CPEC anchor
- Kyaukpyu (Myanmar) — pipeline terminus
- Djibouti — China’s first overseas military base
Great Nicobar as a counter-String of Pearls position allows India to monitor shipping lanes and project naval power into the Bay of Bengal and Indian Ocean without being dependent on regional partners.
Civilian Economic Case
- India’s transshipment dependence costs: $250–350 million annually in fees to Colombo, Singapore, Klang
- A domestic hub captures this revenue and enables India to offer competitive transshipment services to neighbouring countries (Bangladesh, Myanmar, Sri Lanka, Maldives)
Governance — Clearances and Legal Challenges
| Stage | Status |
|---|---|
| Environment Clearance (MoEFCC) | Granted — October 2022; challenged in NGT |
| Forest Clearance | Stage I granted |
| Coastal Regulation Zone (CRZ) clearance | Granted |
| National Green Tribunal | February 2026: Upheld clearances citing strategic + national importance |
| Supreme Court | Petitions pending (filed by environmental groups + tribal rights activists) |
Key legal arguments against:
- EIA process was inadequate (no cumulative impact; no independent biodiversity survey)
- FPIC not obtained from Shompen (Forest Rights Act violation)
- High Tide Line and CRZ norms compromised for port
- UNESCO Biosphere Reserve nomination incompatible with the project scale
