Great Nicobar Island Project: Strategic and Environmental Debate (UPSC)

The Great Nicobar Island Development Project is one of India’s most ambitious and most contested infrastructure proposals. Announced in 2020–21 by NITI Aayog and led by the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO), the Rs 72,000 crore-plus plan will transform the country’s southernmost inhabited island into a strategic, economic and tourism hub. Supporters see it as a geoeconomic counterweight to China’s Indo-Pacific projection. Critics see it as an ecological and human-rights disaster wrapped in a strategic narrative.

Location and Significance

• Great Nicobar is the southernmost and largest island of the Nicobar group, covering 910 sq km of mostly tropical rainforest in the southeastern Bay of Bengal.
• Indira Point on the island is India’s southernmost point, only 90 nautical miles from Sabang in Sumatra, Indonesia.
• The island hosts two national parks — Campbell Bay National Park and Galathea National Park — and the Great Nicobar Biosphere Reserve (designated under UNESCO's Man and the Biosphere Programme).
• It is home to the Shompen (a Particularly Vulnerable Tribal Group — PVTG) and Nicobarese tribal communities, plus a few thousand non-tribal settlers.

Strategic Location

Great Nicobar sits astride the mouth of the Strait of Malacca, through which roughly 30% of global maritime trade and 60% of India's trade pass. The island is closer to Bangkok and Jakarta than to mainland India. Combined with Car Nicobar and Campbell Bay, it anchors the Andaman & Nicobar Command — India's only tri-services command.

Components of the Project

The mega infrastructure plan, spearheaded by ANIIDCO, includes four flagship components:

International Container Transshipment Terminal (ICTT)

• Proposed at Galathea Bay in the southeastern corner.
• Designed as a 16-million-TEU transshipment hub.
• Aims to capture traffic currently handled by Colombo, Singapore and Klang — Indian cargo now routed through these ports involves cost and delay.
• Competitor positioning against Colombo (which itself handles roughly 50% of India's transshipment cargo) is central to the project's commercial case.

Greenfield International Airport

• Dual civilian-military use.
• Peak hour capacity for 4,000 passengers.
• Runway length and facilities designed to handle long-haul aircraft and strategic military assets.

Township

• Planned residential, commercial and administrative areas.
• Target population ~6.5 lakh over a generation — a dramatic change for an island that currently has fewer than 10,000 residents.

Power Plant

• Gas and solar-based hybrid power generation.
• Planned capacity around 450 MW to support all other components.

Implementation and Approvals

• NITI Aayog highlighted strategic potential of the island in a report that triggered the project.
• Galathea Bay — the proposed site for the ICTT and power plant — is officially uninhabited, located in the southeastern corner.
• Environmental Clearance and In-principle Forest Clearance were granted in October 2022.
• A detailed project report (DPR) has been prepared.
• Expert Appraisal Committee reviewed the project; environmental clearance was issued with conditions.
• The government is expected to invite bids for the initial construction phase in phases.

Strategic Importance

Security Interests

• The Bay of Bengal and Indian Ocean region are crucial for India’s maritime security, particularly against the expanding presence of the Chinese People’s Liberation Army Navy (PLAN).
• India's concerns include Chinese activity at key Indo-Pacific chokepoints — Malacca, Sunda and Lombok Straits.
• A developed Great Nicobar strengthens India's "first island chain" presence in the eastern Indian Ocean.

Military Upgrades

The island development is coordinated with significant military infrastructure upgrades:

• Revamped airfields and jetties.
• Additional logistics and storage facilities.
• Base for military personnel.
• Enhanced surveillance infrastructure — radar, EEZ monitoring.

These support deployment of additional warships, aircraft, missile batteries and troops. The Andaman & Nicobar Command becomes a more capable forward platform.

Economic and Trade

• Transshipment hub reduces dependence on Colombo and Singapore.
• Blue economy — fisheries, tourism, marine services.
• Act East Policy — physical anchor for deeper links with ASEAN.

Environmental and Ethical Concerns

Tribal Rights

• The Shompen are a Particularly Vulnerable Tribal Group (PVTG) — fewer than 300 individuals, practising a hunter-gatherer lifestyle in the interior forests.
• The Nicobarese on Great Nicobar number a few hundred.
• Anthropologists and former administrators have written open letters warning that the project could cause "genocide" of the Shompen through disease, displacement and cultural disruption.
• Tribal Council of Great and Little Nicobar Islands objected to the consultation process as inadequate.

Forest and Biodiversity Loss

• Nearly 8.5 lakh to 10 lakh trees (varying estimates) to be felled across approximately 130 sq km of primary rainforest.
• Coral reef destruction in Galathea Bay.
• Threat to the Nicobar Megapode — a ground-nesting bird endemic to these islands; Galathea is a critical nesting site.
• Threat to leatherback turtles — among the world's largest nesting aggregations occurs on Galathea Bay beaches.
• Loss of Galathea Wildlife Sanctuary — denotified to allow construction.
• Impact on Saltwater crocodile, Nicobar macaque, coconut crab, hawksbill turtle populations.

Seismic and Tsunami Vulnerability

• The island sits on the Indonesian-Andaman seismic arc.
• Indira Point subsided 4.25 metres during the December 2004 tsunami, which killed hundreds of Nicobarese.
• A major infrastructure corridor in this zone raises tsunami exposure for investments and inhabitants.

Climate Impacts

• Loss of carbon-rich rainforest undermines climate commitments.
• Mangrove, reef and beach ecosystems damaged — these are India's natural climate defences.

Inadequate Consultation

• Tribal Councils allege consultation was hasty and not in keeping with Forest Rights Act provisions.
• Multiple experts have challenged the EIA report for data gaps.

Judicial and Expert Review

• National Green Tribunal (NGT) in 2023 set up a high-powered committee to re-examine environmental clearance.
• The NGT committee subsequently upheld the clearance with conditions, but controversy continues.
• PILs in Supreme Court on Shompen rights and environmental impact have been filed.
• Standing Committee of Parliament on Science and Technology, Environment, Forests and Climate Change has reviewed the project multiple times.

Way Forward

• Independent re-evaluation of EIA by a multidisciplinary panel including anthropologists, climate scientists, marine biologists and seismologists.
• Strict no-go zones around Shompen habitation and key nesting sites.
• Phased implementation with ecological and social monitoring between phases.
• Tribal consent framework aligned with the Forest Rights Act and PESA principles.
• Seismic-resilient engineering with updated tsunami hazard modelling.
• Transshipment-first, township-later sequencing to reduce front-loaded ecological impact.
• Transparent, public disclosure of mitigation plans, monitoring data and compensation.

Latest Developments (2024–26)

Updated context:

• NGT committee report (2023) largely upheld environmental clearance with conditions, but the controversy remains live.
• Standing Committee hearings (2024) continued to flag consultation and ecological issues.
• Civil society and former bureaucrats have written to the President and PM in 2024–25 asking for a pause.
• Construction phase tenders have been floated in 2024 for preparatory works.
• Shompen voting in 2024 Lok Sabha elections — seven Shompen tribals voted for the first time ever, drawing global attention to tribal rights debate.
• Cyclone impacts in Bay of Bengal (2024) — Cyclone Remal and others — have added climate-risk concerns.
• ANIIDCO updated DPR (2024) partially addresses mitigation but critics remain unconvinced.
• The Disaster Management (Amendment) Act 2025 mandates tsunami-risk integration for coastal infrastructure.
