Great Nicobar Development Project

1. Introduction

The Great Nicobar Development Project (GNDP) is one of India’s largest integrated infrastructure and strategic development projects, aimed at transforming Great Nicobar Island in the Andaman and Nicobar Islands into a global maritime, logistics, defence and economic hub. The project is being implemented by the Andaman and Nicobar Islands Integrated Development Corporation Ltd. (ANIIDCO) under the guidance of NITI Aayog and the Ministry of Home Affairs. The estimated project cost is about ₹72,000 crore and it will be implemented in phases over nearly 30 years.

Great Nicobar Island is India’s southernmost island, with Indira Point marking the southernmost tip of the country. It lies just about 40 nautical miles (≈75 km) from the East–West International Shipping Route near the Strait of Malacca, through which nearly 30% of global maritime trade and a significant share of global energy shipments pass. This location gives the island immense geostrategic importance for maritime security, trade and India’s Indo-Pacific strategy.

The Great Nicobar Project notes highlight the need to balance economic development, national security and environmental conservation by creating world-class infrastructure while incorporating safeguards for biodiversity and indigenous communities.

  • Phase III (2042–2047) – 48.71 sq. km

3. Strategic and Economic Significance

Strategic Location in the Indian Ocean Region

Great Nicobar Island occupies one of the most strategic locations in the Indian Ocean Region (IOR). It is situated only about 40 nautical miles (≈75 km) from the East–West International Shipping Route passing through the Strait of Malacca, one of the busiest maritime chokepoints in the world. According to the World Economic Forum, nearly 94,000 ships transit the Strait of Malacca annually, carrying around 30% of global trade and nearly one-third of global seaborne oil trade. This geographical advantage enables India to strengthen its presence in the Indo-Pacific and emerge as a key maritime power.

Maritime Trade and Logistics Hub

India currently depends heavily on foreign ports such as Colombo (Sri Lanka), Singapore and Port Klang (Malaysia) for transshipment of a significant share of its container cargo. The proposed International Container Transshipment Terminal (ICTT) at Galathea Bay, with an ultimate capacity of 14.2 million TEUs, will reduce this dependence and improve India’s logistics competitiveness. The port’s natural depth of over 20 metres allows it to accommodate the world’s largest container vessels without extensive dredging, making it one of the most competitive deep-water ports in the Bay of Bengal. The Great Nicobar Development Project is expected to save substantial foreign exchange and attract international shipping lines to Indian ports.

Strengthening National Security and Defence

The project has immense strategic value for India’s maritime security. The Government has described it as a project of “strategic, defence and national importance.” Development of modern port, airport and logistics infrastructure will enhance India’s surveillance and operational capabilities in the Andaman Sea, facilitate faster deployment of defence assets and strengthen monitoring of critical Sea Lines of Communication (SLOCs). It will also reinforce India’s Act East Policy, Indo-Pacific Oceans Initiative (IPOI) and efforts to counter strategic challenges in the Indian Ocean Region, including the growing influence of external powers under the so-called “String of Pearls” strategy.

Economic Growth and Employment Generation

The Great Nicobar Project is expected to become a major engine of economic development for the Andaman & Nicobar Islands. Besides the port, it includes a greenfield international airport, 450 MVA gas-solar power plant and planned township, creating a comprehensive economic ecosystem. According to the Ministry of Ports, Shipping and Waterways, the transshipment port alone is expected to generate approximately 3,500 jobs during construction, 1,700 direct jobs and 350 indirect jobs after commissioning. The project will also stimulate investment in logistics, ship repair, bunkering, warehousing, tourism and other allied maritime industries.

Promoting the Blue Economy and Regional Development

The project aligns with India’s vision of a Blue Economy by promoting sustainable utilisation of marine resources while enhancing port-led development. It complements initiatives such as Maritime India Vision 2030, Amrit Kaal Vision 2047 and the Sagarmala Programme. Improved connectivity through the international airport and modern infrastructure is expected to boost tourism, fisheries, trade and services in the Andaman & Nicobar Islands, integrating the region more closely with Southeast Asia and global value chains. The Government considers the Great Nicobar Development Project a catalyst for transforming Great Nicobar into a major economic and strategic hub in the Indo-Pacific.

4. Environmental and Ecological Concerns

Large-Scale Forest Diversion and Tree Felling

The Great Nicobar Development Project has generated widespread environmental debate because it involves the diversion of 130.75 sq. km of forest land, representing 1.82% of the total forest cover of the Andaman and Nicobar Islands. According to the Government, around 18.65 lakh trees exist in the project area, while the maximum number likely to be felled is about 7.11 lakh trees in a phased manner. Environmentalists argue that the project could fragment one of India’s last remaining tropical evergreen rainforests, which support a large number of endemic flora and fauna. Although the Government has earmarked 65.99 sq. km as green zones and proposed 97.30 sq. km of compensatory afforestation in Haryana, critics contend that mainland plantations cannot ecologically replace ancient island rainforests.

Threat to Biodiversity and Endemic Species

Great Nicobar Island forms part of the UNESCO-designated Great Nicobar Biosphere Reserve and is one of India’s richest biodiversity hotspots. It is home to several endemic and threatened species, including the Leatherback Sea Turtle, Nicobar Megapode, Saltwater Crocodile, Nicobar Crab-eating Macaque and numerous endemic birds, reptiles and plants. Environmental groups have expressed concern that construction of the transshipment port, airport and township could lead to habitat fragmentation, increased human disturbance and pressure on wildlife. In response, the Government has mandated biodiversity conservation plans prepared by institutions such as the Wildlife Institute of India (WII), Zoological Survey of India (ZSI) and Salim Ali Centre for Ornithology and Natural History (SACON).

Impact on Leatherback Sea Turtle and Marine Ecosystem

Galathea Bay, where the proposed International Container Transshipment Terminal is planned, is among the most important nesting habitats of the critically endangered Leatherback Sea Turtle in the Indian Ocean. Environmentalists fear that dredging, increased ship traffic, underwater noise and artificial lighting may adversely affect turtle nesting and hatchling survival. Concerns have also been raised regarding coral reefs, mangroves and marine biodiversity. The Government, however, maintains that the western nesting beaches will remain protected, a dedicated Leatherback Turtle Conservation Plan has been prepared, and the Wildlife Institute of India is monitoring turtle nesting and movement. Coral conservation and transplantation plans have also been developed by the Zoological Survey of India.

Seismic and Climate Vulnerability

Great Nicobar Island lies in Seismic Zone V, India’s highest earthquake-risk zone, and was among the worst-affected regions during the 2004 Indian Ocean tsunami, when Indira Point subsided by nearly 4 metres. Experts argue that developing large-scale infrastructure in such a geologically fragile region requires rigorous disaster-resilient planning. In addition, climate change-induced sea-level rise, coastal erosion and extreme weather events could increase long-term risks to ports, airports and coastal settlements. These concerns have led to demands for continuous environmental monitoring and periodic review of disaster preparedness measures.

Concerns over Carrying Capacity and Ecological Sustainability

Ecologists have questioned whether Great Nicobar’s fragile island ecosystem can sustain the scale of the proposed development. The project envisions substantial growth in infrastructure and population, raising concerns about freshwater availability, waste management, pollution, invasive species and pressure on natural resources. Critics argue that island ecosystems have limited carrying capacity, making them more vulnerable than mainland ecosystems. To address these concerns, the Government has imposed 42 environmental clearance conditions, constituted separate monitoring committees for pollution, biodiversity and tribal welfare, and established an overarching committee under the Chief Secretary, Andaman & Nicobar Administration to oversee compliance.

5. Impact on Indigenous Communities

Impact on the Shompen Tribe (PVTG)

The Shompen are a Particularly Vulnerable Tribal Group (PVTG) and one of India’s most isolated indigenous communities. According to official data, their population is about 237, and they primarily depend on hunting, gathering and forest resources for their livelihood. Since a significant part of the project area overlaps with the Shompen Tribal Reserve, concerns have been raised regarding habitat fragmentation, increased human interaction, spread of diseases and erosion of their traditional way of life.

Impact on the Nicobarese Community

The Nicobarese, a Scheduled Tribe, have a population of around 1,094 on Great Nicobar Island and largely depend on fishing, coconut cultivation and coastal resources. Environmental groups fear that rapid urbanisation, tourism and industrial activities may affect their traditional livelihoods, cultural identity and access to natural resources. However, the Government has clarified that no Nicobarese settlements will be displaced under the project.

Tribal Reserve and Legal Issues

Out of the 166.10 sq. km proposed for development, 84.10 sq. km overlaps with the notified Tribal Reserve. After excluding 11.032 sq. km that has been under revenue use since 1972, about 73.07 sq. km is proposed to be de-notified. To compensate, the Government has proposed re-notification of 76.98 sq. km as Tribal Reserve, resulting in a net increase of 3.912 sq. km in the reserve area. The Great Nicobar Project notes state that the project is stated to comply with the Forest Rights Act, 2006, the Shompen Policy, 2015, the Jarawa Policy, 2004, and the Andaman & Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956 (ANPATR).

Debate over Tribal Rights and Consent

One of the major controversies surrounding the Great Nicobar Development Project is whether free, prior and informed consent of indigenous communities has been adequately obtained. Public interest litigations have questioned compliance with the Forest Rights Act, 2006, alleging procedural deficiencies in obtaining tribal consent. On the other hand, the Government maintains that the project has received a No Objection Certificate (NOC) from the Ministry of Tribal Affairs, consultations were held with the Anthropological Survey of India, Directorate of Tribal Welfare and other experts, and no displacement of tribal communities is proposed.

Government Measures for Tribal Protection

To safeguard indigenous communities, the Government has constituted a dedicated Monitoring Committee to oversee the welfare of the Shompen and Nicobarese, along with separate committees for biodiversity and pollution monitoring. An Overarching Committee under the Chief Secretary, Andaman & Nicobar Administration has also been established to monitor compliance with environmental and tribal welfare conditions throughout the implementation of the project.

6. Government’s Stand and Mitigation Measures

• Project of National Importance: The Government has described the Great Nicobar Development Project as a project of strategic, defence and national importance, aimed at strengthening India’s maritime security, Indo-Pacific presence and reducing dependence on foreign transshipment ports while ensuring balanced environmental protection.
• Comprehensive Environmental Assessment: The project received Environmental Clearance (EC) under the EIA Notification, 2006 and ICRZ Notification, 2019 after screening, scoping, public consultation and appraisal by the Expert Appraisal Committee (EAC). A detailed Environmental Management Plan (EMP) has been prepared to minimise environmental impacts during both construction and operational phases.
• 42 Environmental Clearance Conditions: The Ministry of Environment, Forest and Climate Change (MoEFCC) imposed 42 specific conditions covering air and water quality, waste management, marine ecology, disaster management, human health, energy conservation, transport and biodiversity protection.
• Scientific Studies by Expert Institutions: Environmental studies were conducted by leading institutions including the Wildlife Institute of India (WII), Zoological Survey of India (ZSI), Salim Ali Centre for Ornithology and Natural History (SACON), Indian Institute of Science (IISc), NIOT, NCCR and NIO. The Government states that these studies concluded that the project can proceed with appropriate safeguards and mitigation measures.
• Forest Conservation Measures: Although 130.75 sq. km of forest land is proposed for diversion, the Government has stated that this constitutes only 1.82% of the total forest cover of the Andaman & Nicobar Islands. Tree felling will be carried out phase-wise, while 65.99 sq. km will remain as green zones with no tree felling. Compensatory afforestation has been planned on 24,750.93 hectares, including land in Haryana and Madhya Pradesh, in accordance with forest conservation guidelines.
• Biodiversity Conservation: The project includes dedicated Biodiversity Conservation Plans, Coral Conservation and Translocation Plans, Leatherback Sea Turtle Conservation Plan, and Nicobar Megapode Conservation Programme. Long-term ecological monitoring has also been mandated.
• Protection of Tribal Communities: The Government maintains that no displacement of the Shompen or Nicobarese tribes is proposed. The project has been designed in accordance with the Forest Rights Act, 2006, Shompen Policy, 2015, Jarawa Policy, 2004, and ANPATR, 1956. It has also received a No Objection Certificate (NOC) from the Ministry of Tribal Affairs after consultations with the Anthropological Survey of India and other stakeholders.
• Institutional Monitoring Mechanism: Three independent Monitoring Committees have been constituted to oversee pollution control, biodiversity conservation, and tribal welfare. In addition, an Overarching Committee under the Chief Secretary, Andaman & Nicobar Administration has been established to coordinate implementation and ensure compliance with all EC/CRZ conditions.

7. Challenges and Criticism

• Balancing Development and Conservation: The biggest challenge is achieving a balance between India’s strategic and economic objectives and the conservation of one of the country’s most ecologically sensitive island ecosystems. Critics argue that large-scale infrastructure development may irreversibly alter the fragile ecology of Great Nicobar.
• Forest Loss and Habitat Fragmentation: The diversion of 130.75 sq. km of forest land and large-scale tree felling could fragment tropical rainforests and threaten endemic flora and fauna despite mitigation measures proposed by the Government.
• Threat to Indigenous Communities: Environmentalists and tribal rights groups have expressed concerns that increased human activity may adversely affect the Shompen (PVTG) and Nicobarese communities through habitat disturbance, cultural change and possible disease transmission.
• Geological and Disaster Risks: Great Nicobar lies in Seismic Zone V and was severely affected by the 2004 Indian Ocean tsunami. Experts caution that major infrastructure projects in such a tectonically active region require robust disaster-resilient planning.
• Environmental Litigation and Public Opposition: The project has faced legal challenges before the National Green Tribunal (NGT) and criticism from environmental groups regarding the adequacy of the Environmental Impact Assessment (EIA), public consultation process and biodiversity safeguards.
• Implementation Challenges: The project’s remote island location, high construction costs, logistical constraints, shortage of skilled manpower and need for continuous environmental monitoring may delay implementation and increase overall costs.
