Great Nicobar Island Development Project
Planned project in India
From Wikipedia, the free encyclopedia
The Great Nicobar Island Development Project is a large infrastructure initiative proposed by the Government of India for Great Nicobar Island in the Andaman and Nicobar Islands, aimed at building an international container transshipment terminal, a dual‑use civil and military airport, a power plant and a township. The project is intended to strengthen India’s strategic presence in the Indian Ocean region and reduce reliance on foreign transshipment hubs by leveraging the island’s proximity to major shipping routes such as the Strait of Malacca.[1]

The proposal has attracted scrutiny from environmental groups, researchers and opposition politicians over concerns about its ecological impacts, including forest diversion, effects on coastal and marine ecosystems, and potential impacts on indigenous communities such as the Shompen and Nicobarese peoples.[2]
History
A feasibility report, commissioned by NITI Aayog, was prepared by AECOM India. On 25 May 2021, terms of reference of project was granted after meeting held by Expert Appraisal Committee.[2][3]
Geography
Excluding the area from Campbell Bay on eastern side of the island to the Galathea Bay in the south and the whole southern tip, the rest of Great Nicobar Island is part of Galathea National Park and the larger Campbell Bay National Park.[4] Galathea River, flowing north to south, meets the Indian Ocean at Galathea Bay.[5] Indira Point adjacent to the Galathea Bay, India's southernmost point,[6] is 145 km or 80 nautical miles north of Indonesia's northernmost island, Rondo Island in Sabang district of Aceh province of Sumatra,[7] near to which is Indonesia's deep sea port, Sabang (612 km or 330 nautical miles south of Indira Point), jointly upgraded by India and Indonesia in 2019 under the strategic military and economic collaboration to protect the channel between Great Nicobar Island and Rondo Island.[8]
Great Nicobar sits atop a major seismic fault line: an earthquake with its epicenter around 80 miles from Great Nicobar contributed to the tsunami in 2004, which killed 230,000 people and displaced millions in Indonesia, India, and Sri Lanka. The day the tsunami struck, Great Nicobar’s southern tip sank by around 15 feet, slipping into the ocean. Most settlements on its coast were washed away. The seismic faultline continues to be active. In July 2025, a geologist warned that an ongoing cluster of smaller earthquakes near the Nicobar Islands could signal a volcanic eruption in the Andaman Sea. This raises fears of another tsunami.[9]
Holistic Master Plan for this project, outside the Galathea National Park, covers an area of 166.10 sq km covering seven revenue villages, which fall under the jurisdiction of three Gram Panchayats.[10]
Project
The total project cost is ₹75,000 crore (US$9.4 b in 2022)[11] and corrected to ₹81,000 crore[12] in 2025, was conceived by NITI Aayog and is being developed by Andaman and Nicobar Islands Integrated Development Corporation (ANIIDC).[13][2] offering geostrategic importance for defence, logistics, commerce and industries, eco-tourism, coastal tourism, and Coastal Regulation Zone.[14] The project, to be completed in phases over 30 years,[15] includes:
- Galathea Bay International Container Transhipment Terminal (Galathea Bay ICTT) on eastern side of Galathea Bay with total 16 million TEU (twenty-foot equivalent units unit of cargo) capacity,[2] with phase-I capacity of 4 million TEUs.[16][4]
- Great Nicobar International Airport (GNIA), a greenfield airport on immediate northeast side of Galathea Bay with peak hour capacity of 4,000 passengers.[2][4]
- Great Nicobar Gas and Solar Power Plant (Great Nicobar GSPP) on immediate northwest side of and Galathea Bay with 450 MVA capacity, spread over 16,610 hectares.[2][4]
- Two new greenfield coastal cities[2] one on the southeast side of the Great Nicobar Island between Campbell Bay and Galathea Bay and another on southwest side of the Great Nicobar Island to the west of Galathea Bay.[4]
Other project components also include:
Existing infrastructure

INS Baaz naval base with existing airstrip at Campbell Bay, under the Andaman and Nicobar Command, connects island with Car Nicobar and Port Blair Air bases.[17][18]
Environmental impact
After weighing the following pros and cons, benefits, risk and mitigation strategies, the project was granted the environmental clearance by the Ministry of Environment, Forest and Climate Change (MoEFCC)'s Expert Appraisal Committee in November 2022.[19][20]
Flora and tree felling
The project involves large‑scale diversion of forest land for infrastructure development, including a transshipment terminal, airport, township and associated facilities. According to the Government of India’s response to a parliamentary question, the Ministry of Environment, Forest and Climate Change estimated that approximately **964,000 trees (about 9.64 lakh)** would be affected by tree felling associated with the project’s forest land diversion, based on figures provided by the junior environment minister in 2024.[21]
These estimates come from official annexures and responses on the environment ministry’s website, which stated that the number of trees to be felled would be about 852,245, with the figure of less than 964,000 based on the proportion of cleared forest area where felling is envisaged.[22]
Some independent scientists have expressed concern that these official estimates may be underestimates, arguing that forest density in parts of Great Nicobar is higher than assumed and that actual tree loss could be significantly greater if denser stands are cleared, potentially affecting millions of trees.[23]
Coral
The Zoological Survey of India’s (ZSI) 2021 Environmental Impact Assessment (EIA) for the project noted that coral colonies within parts of the proposed construction area would need to be translocated to mitigate impacts.[24]
Maps prepared in 2020 by the National Centre for Sustainable Coastal Management (NCSCM), under MoEFCC, showed coral reefs along sections of Great Nicobar’s southern and western coasts, including in Galathea Bay, where a transshipment terminal is proposed. Updated NCSCM maps released in 2021 depicted coral reefs farther offshore and showed a reduced extent of CRZ-IA zones along parts of the coastline.[24]
Fauna
The Great Nicobar project, located within 10 km radius ecologically sensitive zone near Galthea Bay, threatens rare fauna such as Leatherback sea turtle, salt water crocodile, Nicobar macaque.[25] Like all islands in the region which have been isolated over geological time which have led to the evolution of numerous endemic species, several yet to be discovered and formally named. The "Great Nicobar crake" is an undescribed species of bird as of 2026 while the wolf snake Lycodon irwini was described only in 2025.[26] While the MoEFCC proposed 3 conservation sites on Little Nicobar, Menchal Island and Meroe Island to mitigate risks, the Tribal Council of Campbell Bay opposes these sanctuaries, citing a lack of consultation and their long-standing coexistence with the island's wildlife.[19][27]
Human
This project which includes two new planned cities in the region will increase population to over 350,000, which may cause a threat to the indigenous communities.[28] After the environmental clearance by MoEFCC, some experts and researchers expressed concerns to Ministry of Tribal Affairs about vulnerability of indigenous communities on the island. Around 1761 individuals belonging to the indigenous Shompen and Nicobarese tribes live in the island. 853 square kilometres (approximately 92% of the total area) of the Great Nicobar Island is designated as tribal reserve under the Andaman and Nicobar Protection of Aboriginal Tribes Regulation, 1956. This means that the land is meant for exclusive use of the community and others cannot access the area without their express permission. Around 10% of tribal reserve of the island will be affected by this project. Indigenous people live outside the project area and the tribal reserve also falls outside the project area.[28] According to Forest Rights Act, 2006, Shompen people are legal sole authority to preserve the forest reserve.[28][29] Survival International, a global NGO campaigning for indigenous rights, has said that the mega-development will put the Shompen at risk of being wiped out. In February 2024, 39 genocide experts from 13 countries warned that the development “will be a death sentence for the Shompen, tantamount to the international crime of genocide”. They said that the proposed population increase and exposure to outside populations would lead to mass deaths because the Shompen have little to no immunity to infectious outside diseases.[30]
