The Indian government has sanctioned a ₹72,000-crore mega-infrastructure initiative called the ‘Holistic Development of Great Nicobar Island’ to transform the island into a major transshipment and defence hub. Spearheaded by NITI Aayog, the project covers around 18% of the island’s total land area. It envisions an integrated city-state designed to serve both commercial and military purposes. The project's primary source of controversy has been speed, which critics argue is part of government efforts to sidestep due diligence. The project involves denotifying parts of a UNESCO Biosphere Reserve and tribal reserve. Galathea Bay, a crucial nesting site for the giant leatherback turtle, will be affected by the construction of breakwaters and dredging for the port. An estimated 9.64 lakh trees will be cut to build the township and airport, impacting the habitat of the Nicobar megapode and the Nicobar tree shrew. The government proposes planting trees in Haryana to compensate for the deforestation, a move ecologists criticize as inadequate. The island is home to two distinct indigenous groups, the Nicobarese and the Shompen. The Shompen, a Particularly Vulnerable Tribal Group (PVTG), face the risk of epidemics due to increased contact with outsiders. The Nicobarese, relocated after the 2004 tsunami, are barred from returning to their ancestral lands due to the project. Reports indicate that the Tribal Council initially issued a ‘no objection certificate’ but later withdrew it, alleging they were rushed into signing without understanding the implications. In 2023, the National Green Tribunal temporarily stayed the project but later allowed it to proceed.

Background

The Great Nicobar Island project raises critical questions about balancing development with environmental protection and the rights of indigenous communities. Understanding the historical context of environmental regulations and tribal rights in India is crucial. India's environmental legislation has evolved significantly since the 1972 Stockholm Conference. Key milestones include the Water (Prevention and Control of Pollution) Act of 1974 and the Environment (Protection) Act of 1986, enacted after the Bhopal gas tragedy. These laws established frameworks for environmental impact assessments and pollution control, which are now central to debates surrounding projects like the one in Great Nicobar. The protection of tribal rights is enshrined in the Indian Constitution, particularly in Article 21 (Right to Life and Personal Liberty) and Article 46 (promotion of educational and economic interests of Scheduled Castes, Scheduled Tribes, and other weaker sections). The Fifth and Sixth Schedules provide special provisions for the administration and control of Scheduled Areas and Scheduled Tribes. The Forest Rights Act of 2006 (FRA) further strengthens the rights of tribal communities over forest resources, a key consideration in the Great Nicobar project. Globally, the concept of sustainable development, as articulated in the Brundtland Report (1987) and Agenda 21 (1992), emphasizes the need to integrate environmental and social considerations into economic planning. International conventions like the Convention on Biological Diversity (CBD) also influence India's approach to biodiversity conservation and the management of protected areas like UNESCO Biosphere Reserves.

Latest Developments

The Great Nicobar Island project is unfolding amidst growing concerns about environmental clearances and tribal rights. Recent developments highlight the complexities of balancing national development goals with ecological sustainability. In recent years, there has been increased scrutiny of environmental impact assessments (EIAs) for large infrastructure projects. The government's emphasis on streamlining environmental clearances has been met with criticism from environmental groups, who argue that it could weaken environmental safeguards. The debate over the Great Nicobar project reflects this tension, with concerns raised about the potential impact on biodiversity and the displacement of indigenous communities. The role of NITI Aayog in pushing for the project has also drawn attention to the influence of economic considerations in environmental decision-making. The rights of Particularly Vulnerable Tribal Groups (PVTGs) have been a focal point of discussion. The Shompen community's vulnerability to external influences and diseases raises questions about the adequacy of measures to protect their health and cultural integrity. The implementation of the Forest Rights Act, 2006, and its impact on the Nicobarese community's access to their ancestral lands, are also under scrutiny. Court decisions and the interventions of bodies like the National Green Tribunal (NGT) play a crucial role in shaping the project's trajectory. Looking ahead, the success of the Great Nicobar project will depend on the government's ability to address environmental concerns, protect tribal rights, and ensure transparency in decision-making. The project could serve as a test case for India's commitment to sustainable development and its ability to balance economic growth with social and environmental considerations. The long-term impacts on the island's ecosystem and the well-being of its inhabitants will be closely monitored by environmentalists, tribal rights activists, and policymakers alike.

Practice Questions (MCQs)

1. Consider the following statements regarding the Great Nicobar Island project: 1. The project is spearheaded by NITI Aayog and covers approximately 18% of the island's total land area. 2. The project involves denotifying parts of a UNESCO Biosphere Reserve and a tribal reserve. 3. The government proposes planting trees in Haryana to compensate for the deforestation caused by the project. Which of the statements given above is/are correct?

  • A.1 and 2 only
  • B.2 and 3 only
  • C.1 and 3 only
  • D.1, 2 and 3
Show Answer

Answer: D

All three statements are correct. The Great Nicobar Island project is indeed spearheaded by NITI Aayog and covers around 18% of the island. It does involve denotifying parts of a UNESCO Biosphere Reserve and tribal reserve. The government's proposal to plant trees in Haryana to compensate for deforestation is also accurate, although its ecological effectiveness is debated. Therefore, the correct answer is D.

2. Which of the following statements accurately describes the potential impact of the Great Nicobar Island project on the local ecology?

  • A.The project will have no impact on the nesting sites of the giant leatherback turtle.
  • B.Approximately 9.64 lakh trees will be cut to build the township and airport, impacting the habitat of the Nicobar megapode and the Nicobar tree shrew.
  • C.The project will enhance the existing UNESCO Biosphere Reserve.
  • D.The project will not affect the indigenous tribal groups living on the island.
Show Answer

Answer: B

Option B is the correct answer. The project involves cutting an estimated 9.64 lakh trees, which will significantly impact the habitat of species like the Nicobar megapode and the Nicobar tree shrew. Option A is incorrect because Galathea Bay, a crucial nesting site for the giant leatherback turtle, will be affected. Option C is incorrect as the project involves denotifying parts of the UNESCO Biosphere Reserve. Option D is incorrect because the project will affect the indigenous tribal groups, particularly the Shompen.

3. With reference to the Particularly Vulnerable Tribal Groups (PVTGs) in India, consider the following statements: 1. PVTGs are characterized by a declining or stagnant population, low literacy, and a subsistence economy. 2. The Shompen tribe of Great Nicobar Island is officially designated as a PVTG. 3.
