If you have been solving UPSC papers from the last four to five years, you have probably noticed something. Questions related to India’s island territories — Andaman and Nicobar, Lakshadweep, and even smaller island groups — are appearing more frequently than ever before. This is not a coincidence. It reflects India’s shifting strategic priorities, and as a UPSC aspirant, you need to understand why.
Where This Topic Sits in the UPSC Syllabus
India’s island territories cut across multiple papers and subjects. That is precisely what makes them high-value for the exam. They connect geography, internal security, international relations, environment, and governance — all in one package.
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies | Indian Geography, Current Events of National Importance |
| Mains | GS-I | Physical Geography — Islands, Coral Reefs, Coastal Features |
| Mains | GS-II | India and its Neighbourhood, Bilateral Relations, Act East Policy |
| Mains | GS-III | Internal Security, Border Management, Environment and Biodiversity |
Related syllabus topics include the Indo-Pacific strategy, maritime security, blue economy, and biodiversity hotspots. A single question on Andaman and Nicobar can test your knowledge across three GS papers. That is why I always tell my students to treat island territories as a cross-cutting theme, not a standalone chapter.
The Strategic Shift — Why Islands Matter More Now
For decades, India treated its island territories primarily as tourist destinations or remote administrative units. That era is over. Three major developments have changed everything.
First, China’s expanding naval presence in the Indian Ocean Region has pushed India to strengthen its maritime defences. The Andaman and Nicobar Command — India’s only tri-service command — sits right at the mouth of the Malacca Strait. About 60,000 merchant ships pass through this strait every year. Whoever controls this chokepoint has significant leverage over global trade routes. India’s geographical advantage here is enormous, and the government has finally started investing in it seriously.
Second, the Act East Policy has given the Andaman and Nicobar Islands a new role. These islands are closer to Southeast Asia than to mainland India. Port Blair is just 1,200 km from the Malacca Strait but over 1,400 km from Chennai. India now views these islands as a bridge to ASEAN nations, not a distant outpost.
Third, the Indo-Pacific framework — involving the Quad (India, USA, Japan, Australia) — has made maritime domain awareness a top priority. Lakshadweep’s location in the Arabian Sea complements the Andaman and Nicobar chain in the Bay of Bengal. Together, they give India a two-ocean island presence that very few countries possess.
Key Developments You Must Know for 2026
Let me walk you through the specific developments that UPSC is likely drawing questions from.
INS Jatayu — India commissioned its second naval air station in Minicoy, Lakshadweep. This is significant because Minicoy is India’s closest point to major international shipping lanes in the Arabian Sea. It strengthens India’s surveillance capability in the western Indian Ocean.
Great Nicobar Island Development Project — This is a massive Rs 72,000 crore project involving a transshipment port, an international airport, a power plant, and a township. The project has sparked a major debate between development and environmental conservation. Great Nicobar is home to the Shompen tribe (a Particularly Vulnerable Tribal Group) and the Nicobar Megapode (an endangered bird). The National Green Tribunal and environmental groups have raised concerns. For UPSC, this project is gold — it connects GS-I (geography and tribal societies), GS-II (governance), and GS-III (environment and security).
Lakshadweep Development Plans — The administration has proposed new regulations including the Lakshadweep Development Authority Regulation and the Prevention of Anti-Social Activities Regulation. These have triggered debates around federalism, local governance, and community rights. Understand these from a GS-II perspective.
Blue Economy and Sagarmala — India’s island territories are central to the blue economy push. Deep-sea fishing, ocean energy, seabed mining, and marine biotechnology are all areas where these islands will play a role. The Sagarmala Project specifically targets port-led development in island regions.
The Environmental Dimension — Equally Important
UPSC loves testing the environment angle of island territories. Here is what you need to remember.
The Andaman and Nicobar Islands have two national parks that are biodiversity treasures — Mahatma Gandhi Marine National Park and Campbell Bay National Park. The islands host coral reefs, mangroves, and endemic species found nowhere else on Earth. Barren Island in the Andaman chain is India’s only active volcano.
Lakshadweep is India’s only coral atoll system. The islands are low-lying — most are barely 1-2 metres above sea level. Climate change and rising sea levels pose an existential threat. This connects directly to GS-III questions on disaster management and climate change adaptation.
The Coral Bleaching events in both island groups have been documented by the Zoological Survey of India. If UPSC asks about coral ecosystems in India, your answer must reference these territories.
How UPSC Has Asked About Islands — Past Patterns
In recent Prelims papers, UPSC has asked about the location of specific islands, tribal groups in Andaman and Nicobar (Jarawa, Sentinelese, Onge, Shompen), volcanic islands, and coral reef types. In Mains, questions have appeared on maritime security, the significance of the Indo-Pacific, and the balance between development and tribal rights.
One pattern I have observed is that UPSC rarely asks a standalone geography question about islands anymore. Instead, it wraps the question around a current development. For example, a question may not simply ask “Where is Barren Island?” but instead frame it around volcanic activity, disaster preparedness, or geological features of the Bay of Bengal. This means you cannot prepare island territories in isolation — you must connect them to current affairs.
How to Prepare This Topic Effectively
I recommend a layered approach. Start with the physical geography — know the maps. Be able to locate every major island group, strait, and channel. Use the NCERT Class 11 geography textbook as your base.
Next, build the strategic layer. Read about the Andaman and Nicobar Command, India’s maritime doctrine, and the Indo-Pacific concept. The Ministry of Defence annual report has a useful section on island territories.
Finally, track current affairs. Every new infrastructure project, environmental clearance controversy, or military exercise in these regions is a potential question. Maintain a short note on each development with its GS paper connection.
Key Points to Remember for UPSC
- Andaman and Nicobar Islands straddle the Bay of Bengal near the Malacca Strait — India’s most strategically located territory for Indo-Pacific security.
- Lakshadweep is India’s smallest Union Territory and only coral atoll system, highly vulnerable to sea-level rise.
- The Great Nicobar project tests the development-versus-environment debate and involves tribal rights under the Forest Rights Act.
- INS Jatayu in Minicoy strengthens India’s western Indian Ocean surveillance, complementing the eastern Andaman and Nicobar Command.
- Barren Island is India’s only confirmed active volcano — located in the Andaman Sea.
- The Sentinelese, Jarawa, Onge, and Shompen are Particularly Vulnerable Tribal Groups residing in these islands — a recurring UPSC theme.
- Island territories connect at least three GS papers — treat them as an integrated topic, not isolated geography facts.
India’s island territories are no longer peripheral topics in the UPSC syllabus. They sit at the intersection of geography, security, environment, and governance — exactly where UPSC likes to frame its toughest questions. Start by mapping these islands physically and strategically, then layer current developments on top. A well-prepared answer on this theme can earn you marks across multiple papers, and that kind of efficiency matters in this exam.
