Indira Point ICRZ Clearance Explained: Why a Convention Centre & Museum at India's Southernmost Tip Sparks a Coastal Zone Debate

<mark>Southernmost point of India: </mark> Indira Point is the southernmost tip of India's territory, located at the southern extremity of Great Nicobar Island in the Union Territory of the Andaman and Nicobar Islands. It lies roughly 150 km south-east of the UT capital (Port Blair, officially renamed Sri Vijaya Puram in September 2024) and is only about 90 nautical miles from the Indonesian island of Sumatra, making it a landmark on the busy Colombo–Singapore and Malacca shipping lanes.

<mark>From Pygmalion Point to Indira Point: </mark> The site was historically known as Pygmalion Point (and Parsons Point) in British survey records. It was renamed in honour of former Prime Minister Indira Gandhi, with the official renaming ceremony held on 10 October 1985.

Strategic value: Because of its position near the Malacca Strait and India's eastern maritime approaches, Great Nicobar sits close to several strategic sea lanes. Indira Point serves as a navigational marker and a symbol of India's maritime sovereignty in the region.

The lighthouse: The Indira Point lighthouse is a cast-iron tower painted in red and white bands. It was commissioned into service on 30 April 1972 and guides vessels through one of the world's busiest international shipping corridors.

Impact of the 2004 tsunami: During the December 2004 Indian Ocean earthquake and tsunami, the southern tip of Great Nicobar subsided by about 4.25 metres, partially submerging the lighthouse and washing away nearby families and researchers studying sea turtles. The event is a reminder that the island lies in one of the world's most seismically active zones.

The managing authority: The lighthouse is maintained by the Directorate General of Lighthouses and Lightships (DGLL), a subordinate office of the Ministry of Ports, Shipping and Waterways, headquartered in Noida. The DGLL provides general aids to marine navigation along India's coastline under the Marine Aids to Navigation Act, 2021 (which replaced the older Lighthouse Act, 1927), operating through nine regional directorates, including one at Port Blair (Sri Vijaya Puram).

The legal source: The Coastal Regulation Zone regime is issued by the Ministry of Environment, Forest and Climate Change under Section 3 of the Environment (Protection) Act, 1986. The first CRZ notification came in 1991, was revised in 2011, and the version currently in force is the CRZ Notification, 2019, drafted largely on the recommendations of the Shailesh Nayak Committee.

Purpose: The CRZ framework aims to conserve fragile coastal and marine ecosystems (mangroves, coral reefs, dunes, turtle nesting grounds), protect the livelihoods of fishing and local communities, and allow sustainable, hazard-aware development.

The four zones on the mainland: CRZ-I covers ecologically sensitive areas and the inter-tidal zone; CRZ-II covers developed urban coasts; CRZ-III covers relatively undisturbed rural areas (split into III-A and III-B by population density); and CRZ-IV covers the water area up to 12 nautical miles seaward from the low tide line, plus tidal-influenced water bodies.

Who gives clearance: Projects in the most sensitive CRZ-I and CRZ-IV categories are cleared by the MoEFCC at the Centre, while clearances for CRZ-II and CRZ-III have been delegated to the State/UT level.

Separate rules for islands: The Andaman and Nicobar Islands and Lakshadweep are governed not by the mainland CRZ but by a parallel island framework. Larger islands are managed under the Island Coastal Regulation Zone (ICRZ) and smaller ones under Integrated Island Management Plans (IIMPs), both flowing from the 2019 notification and the earlier Island Protection Zone (IPZ) Notification, 2011.

Island grouping: Group-I islands have a geographical area greater than 1,000 sq km (for example Great Nicobar and South Andaman) and have a No Development Zone of 100 m from the High Tide Line (reduced to 50 m for eco-tourism). Group-II islands (100–1,000 sq km, such as Little Andaman and Car Nicobar) have a 50 m NDZ (20 m for eco-tourism).

The ICRZ categories: Island coasts are classified into ICRZ-IA (ecologically sensitive areas), ICRZ-IB (the inter-tidal zone), ICRZ-II (developed areas), ICRZ-III (rural areas), and the water areas, with ICRZ-IVA being the sea area up to 12 nautical miles from the low tide line.

Meaning of ICRZ-IA: ICRZ-IA covers the most fragile island coastal stretches — coral reefs, mangroves, sand dunes, mudflats, salt marshes, sea turtle nesting grounds, and areas within national parks and sanctuaries. Human interference here is kept to a minimum, and most construction is prohibited.

Meaning of ICRZ-IVA: ICRZ-IVA is the marine water body extending up to 12 nautical miles from the low tide line. Regulation here mainly concerns fishing, navigation and prohibition of untreated waste discharge.

What is still allowed in ICRZ-IA: The notification permits a narrow list of activities — low-impact eco-tourism facilities such as mangrove walks, nature trails and tree huts, and, in exceptional cases, construction of roads and roads on stilts by reclamation only for defence, strategic purposes or public utilities. Such construction requires a detailed environmental impact assessment, a recommendation from the Coastal Zone Management Authority and approval by the MoEFCC; where mangroves are damaged, at least three times the affected area must be replanted.

The core issue: A convention centre and museum are not, on their face, within the eco-tourism/road exceptions, which is why the proposal must obtain clearance and why its classification under ICRZ-IA is central to whether it can proceed. The official position is that the work is to protect the lighthouse and will avoid prohibited activity.

Biosphere reserve: The Great Nicobar Biosphere Reserve was designated under UNESCO's Man and the Biosphere Programme in 2013 and covers most of the island. It contains two national parks — Campbell Bay National Park in the north and Galathea National Park in the south — both gazetted in 1992.

Flagship species: The island hosts rich endemism, including the Nicobar megapode (scrubfowl), the Nicobar long-tailed macaque, the Nicobar tree shrew, the saltwater crocodile, and the giant robber (coconut) crab. The beaches around Galathea Bay are among the most important nesting sites in the northern Indian Ocean for the giant leatherback turtle, the world's largest marine turtle.

Indigenous communities: Great Nicobar is a tribal reserve protected under the Andaman and Nicobar Protection of Aboriginal Tribes Regulation, 1956. It is home to the Shompen — a hunter-gatherer Particularly Vulnerable Tribal Group (PVTG) of roughly 200–300 people — and the Nicobarese.

The mega-project context: The proposal for infrastructure at Indira Point arrives against the backdrop of the much larger Great Nicobar Island Development Project, conceived by NITI Aayog in 2021 and implemented by the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO). It envisages a transshipment port at Galathea Bay, an international airport, a power plant and a greenfield township.

The recurring tension: The project has drawn scrutiny over forest loss, turtle nesting sites and tribal rights, and has been examined by the National Green Tribunal, which upheld the environmental clearance while imposing conservation conditions. The Indira Point clearance question sits within this wider debate about balancing strategic and tourism development with the protection of an exceptionally fragile island ecosystem.

Any clearance should rest on a rigorous, site-specific Environmental Impact Assessment and a clear demonstration that the proposed structures fall within permissible ICRZ-IA activities rather than a relaxation of the notification.

The Coastal Zone Management Authority's recommendation and MoEFCC scrutiny must ensure that lighthouse-protection works do not disturb adjacent turtle nesting beaches, mangroves or national park boundaries.

Development should favour low-footprint, reversible eco-tourism models, with strict caps on construction and mandatory compensatory measures such as mangrove replanting where damage is unavoidable.

Free, prior and informed consultation with the Shompen and Nicobarese, consistent with the tribal-reserve status of the island, should precede any change on the ground.

Given the island's location in a high seismic-risk zone, disaster-resilient design and adherence to No Development Zone norms are essential.
