Abstract
The Great Nicobar Project is a large infrastructure initiative proposed by the Government of India. It intends to improve India’s economic and political standing in the Indo-Pacific region, and is a major development venture that plans for a transhipment port, an airport, a power plant, and a township, while promising to be a sustainable development project. Although it is portrayed to be sustainable, the project continues to raise potential concerns of its impact on the environment, the rights of indigenous people, and the very idea of sustainable development. The Great Nicobar is one of India’s most ecologically sensitive zones, holding rich biodiversity, protected forests, and some of India’s indigenous peoples, like the Shompen tribe. This article discusses how the concept of sustainability in the Great Nicobar Project is problematic due to the inherent contradictions between its promotion and reality. Sustainable development in projects like the Great Nicobar Project signals the emerging trend wherein the concept of sustainability has less to do with limiting the environmental destruction that comes from large-scale ecological change but rather justifies it.
Introduction
The Great Nicobar Project in India is seen as one of the major milestones in terms of the future ambitions of the nation. The estimated cost of this project is around ₹81,000 crores, which looks to build a transhipment port, an international airport, a power plant, and even a large township to make the Great Nicobar a strategic and economic hub. There have been repeated references by the government, calling this project a “sustainable” and “inclusive” development project. However, the project poses an even harder question: What exactly does the concept of “sustainable development” mean when it has a scope of influence so great that it might end up completely changing the ecology of the island itself?
Great Nicobar is certainly one of the most delicate regions of India, with its unique ecosystems formed by dense forest cover, endemic species, and indigenous communities. Here, the contradiction between the rhetoric of sustainability and the impact of large-scale ecological transformation is evident.
Strategic Ambition
The support of the Indian government in this project can be attributed to reasons that are economic as well as geopolitical. Firstly, the Great Nicobar Island lies near the Malacca Straits, which is one of the busiest shipping lanes in the world. This, according to policymakers, means that establishing a transhipment port in Great Nicobar will lower the country’s dependence on external ports like those found in Singapore and Colombo, making it more of a strategic move than a mere infrastructure proposal.
This framing has been pivotal to the public justification of the project. As competition in the Indian Ocean grows, development in the Andaman and Nicobar Islands is being framed as a necessity for India. The project has thus been positioned as an investment in connectivity and security rather than a development project in the traditional sense.
Ecological Costs
Regardless of the justifications, the impact on the environment is severe. The project entails the diversion of an area of 130.75 sq. km of forests, along with cutting down about 9.64 lakh trees. It is among the most significant land use projects to be considered for the islands. Great Nicobar is a component of the Great Nicobar Biosphere Reserve, which, according to UNESCO, is an extremely sensitive ecosystem that supports rare and threatened species.
There has also been emphasis on the Galathea Bay, which has been the proposed area for building the port. Environmentalists have raised concerns about how building the port there will have an adverse impact on the coral formations as well as on one of the nesting grounds of endangered leatherback turtles. The ecological systems are particularly more fragile in such island environments, and recovery from such large-scale disturbances is mostly limited. Especially given that the project will destroy approximately 13,075 hectares (ha) of pristine tropical rainforest, including 8,52,245 trees within the Great Nicobar Biosphere Reserve.
Tribal Rights
The project has also been met with serious social and legal challenges. The Great Nicobar Island houses the Shompen, a Particularly Vulnerable Tribal Group that has had little contact with the outside world, along with the Nicobarese people, whose way of life revolves around the natural environment of the island. The construction of infrastructure and ecological changes can put immense pressure on these populations.
Additionally, there have been allegations against the Forest Rights Act’s due compliance before granting clearance for the project. It has been argued that the Gram Sabha did not have sufficient involvement, and it has been uncertain whether the tribal consent has even been taken in accordance with the spirit of the Forest Rights Act.
The Sustainability Claim
What makes the Great Nicobar Project so controversial is not just its environmental impact, but also the definition of what constitutes sustainability. The government has not disputed the claim that the project will cause environmental damage, but on the other hand, has argued that this could be mitigated by implementing measures like compensatory afforestation, monitoring of wild species, among other regulatory provisions.
This reflects an emerging trend in development thinking, where, instead of avoiding environmental destruction, there seems to be a new tendency for sustainability to become associated with managing environmental destruction through documentation, approvals, and mitigation measures. In other words, under such a system, irreversible ecological change can be justified as long as all the processes of official approval appear to be completed, and a project becomes sustainable.
The National Green Tribunal upheld the project’s clearances in February 2026, stressing the project’s strategic importance and the presence of safeguards. However, the decision demonstrates how environmental concerns can be subordinated when a project is framed as nationally significant. In that sense, the tribunal’s ruling does not settle the sustainability question; it sharpens it.
Conclusion
The Great Nicobar Project is not merely a localised conflict about environmental protection. It serves as a litmus test of whether India grasps the idea of sustainable development in light of growing climatic concerns, regional competition, and disputes over territorial control. On one hand, the project seems promising in terms of expanding economic activity and strengthening India’s position strategically; on the other hand, it entails potentially irrevocable harm to one of the most vulnerable areas of the nation. Therefore, it has been evident that the discussions surrounding the project are able to highlight the use of buzzwords like sustainable development as a choice of language to legitimise actions rather than limit them. Essentially, the idea of sustainability itself sees degradation when such large-scale projects aimed at extensive forest clearance or the displacement of indigenous groups call themselves sustainable development projects.
