Tribes of Andaman & Nicobar Islands

Overview
- The Andaman and Nicobar Islands are home to some of India’s oldest indigenous tribal communities, many of whom remain isolated and vulnerable.
- These tribes are often in focus due to concerns related to conservation, development policies, and protection of indigenous lifestyles.
- The islands are inhabited by six major aboriginal tribes:
- Great Andamanese
- Onge
- Jarawa
- Sentinelese
- Nicobarese
- Shompen
- Particularly Vulnerable Tribal Groups (PVTGs):
- All tribes except the Nicobarese are classified as PVTGs due to extreme vulnerability and declining populations.
- Racial Classification:
- Negrito group (Andaman Islands): Great Andamanese, Onge, Jarawa, Sentinelese
- Mongoloid group (Nicobar Islands): Nicobarese, Shompen
- There exists a clear distinction in culture, language, and lifestyle between tribes of the Andaman and Nicobar groups.
Key Tribal Groups
- Great Andamanese
- Once the largest tribe in the region, now reduced to a very small population.
- Currently settled in Strait Island.
- Decline attributed to diseases and colonial contact.
- Historically known for resistance during the Battle of Aberdeen (1859).
- Onge
- A semi-nomadic hunter-gatherer tribe residing in Little Andaman.
- Known for close dependence on nature and traditional skills such as canoe-making.
- Presently receive government support for sustenance.
- Jarawa
- A nomadic hunting and gathering tribe living along the western coasts of Middle and South Andaman.
- Continue to maintain a relatively isolated lifestyle with limited external interaction.
- Sentinelese
- Inhabit North Sentinel Island and are among the most isolated tribes in the world.
- Known for their hostility towards outsiders, preserving complete autonomy.
- Minimal and rare contact attempts have been made, but they largely remain uncontacted.
- Shompen
- Inhabit the Great Nicobar Island and belong to the Mongoloid group.
- Divided into:
- Coastal/river valley groups
- Interior forest groups (more isolated)
- Practice a semi-nomadic hunter-gatherer lifestyle.
- Nicobarese
- The largest tribal group in the islands, spread across multiple Nicobar Islands.
- Follow a settled lifestyle with agriculture and animal husbandry.
- Social structure is based on a patriarchal joint family system called “Tuhet”, which manages land and resources collectively.
Key Features and Significance
- These tribes represent unique human adaptations to island ecosystems.
- Many groups maintain traditional subsistence practices such as hunting, gathering, and fishing.
- Their isolation has helped preserve distinct languages, customs, and cultural identities.
India’s Nuclear Submarine Capability

Context
- India has inducted its third nuclear-powered ballistic missile submarine (SSBN), INS Aridhaman, into the Indian Navy at Visakhapatnam.
- This induction marks a significant step in strengthening India’s sea-based nuclear deterrence.
- With this, India now possesses three operational SSBNs, enhancing its strategic preparedness and maritime security.
About INS Aridhaman
- INS Aridhaman is a 7,000-tonne nuclear-powered ballistic missile submarine, more advanced than its predecessors.
- It is equipped with eight vertical launch tubes, allowing it to carry a larger payload of nuclear missiles.
- Missile Capability:
- K-15 SLBM: Range up to 750 km
- K-4 SLBM: Range up to 3,500 km
- It can carry:
- Up to 8 K-4 missiles, or
- Up to 24 K-15 missiles
- Compared to INS Arihant, Aridhaman has higher missile capacity and improved technological features.
About Arihant-Class Submarines
- India’s nuclear submarine programme began over three decades ago, with support from DRDO and Russia.
- INS Arihant (2016):
- India’s first SSBN
- Established the nuclear triad after its deterrence patrol in 2018
- INS Arighaat (2024):
- More advanced in design and engineering
- Powered by 83 MW pressurised light-water reactor
- INS Aridhaman (Latest):
- Larger and more capable successor
- S4* (upcoming):
- Under construction, expected to further strengthen capabilities
Strategic Importance
- SSBNs provide second-strike capability, which is crucial for nuclear deterrence.
- Even if land and air bases are destroyed in a first strike, submarines can launch retaliatory nuclear attacks.
- This aligns with India’s “No First Use” nuclear doctrine, where nuclear weapons are used only for deterrence and retaliation.
- Nuclear submarines can remain submerged for long durations, making them difficult to detect and enhancing survivability.
Future Developments
- India is working on additional SSBNs to ensure continuous at-sea deterrence.
- A nuclear-powered attack submarine (SSN) programme is also underway:
- Plan to build indigenous SSNs
- One submarine to be leased from Russia (expected by 2027–28)

Panama Canal

Context: The Panama Canal remains in focus due to its strategic maritime importance and role in global trade routes.
About Panama Canal
- The Panama Canal is an artificial waterway connecting the Atlantic Ocean and the Pacific Ocean.
- It cuts across the Isthmus of Panama, a narrow land bridge in Central America.
- The canal was constructed in 1914 and originally controlled by the United States.
- In 1979, control was transferred to the Panama Canal Commission (joint US–Panama body).
- In 1999, full control was handed over to Panama.
Strategic Importance
- It is one of the two most strategically significant artificial waterways, the other being the Suez Canal.
- It drastically reduces travel distance between the US east and west coasts by about 8,000 nautical miles.
- It serves as a critical global trade chokepoint, facilitating faster and cost-efficient maritime movement.
- Enhances connectivity between major oceans, boosting international trade and logistics efficiency.
Operation / Functioning
- The canal operates using a system of locks and water elevators to move ships across different elevations.
- This design is required because the Pacific Ocean is slightly higher (~20 cm) than the Atlantic Ocean.
- Ships are raised or lowered through lock chambers using gravity-driven water flow.
- The locks function by:
- Flooding → to raise the ship’s level.
- Draining → to lower the ship’s level.
- Thus, the canal acts as a water elevator system, enabling smooth transit between the two oceans.

Force Majeure

What is Force Majeure?
- Force majeure is a legal clause in contracts that allows a party to suspend or terminate obligations without penalty.
- It applies when an extraordinary and unforeseeable event makes contract performance impossible.
- It effectively pauses contractual obligations due to circumstances beyond the control of involved parties.
Origin
- The term “force majeure” is derived from French, meaning “superior force”.
- It originates from civil law systems and is now widely used in international commercial contracts and maritime law.
Aim / Objective
- Provides legal protection to businesses and governments during unavoidable disruptions.
- Prevents penalties, breach-of-contract claims, and financial liabilities when obligations cannot be fulfilled.
- Covers both:
- Acts of God (e.g., earthquakes, floods)
- Acts of Man (e.g., war, strikes, government actions)
Key Features
- Unforeseeability: The event must be unpredictable at the time of contract signing.
- Externality: The cause must arise from an external source, not internal fault or negligence.
- Irresistibility (Impossibility): The event must make performance impossible, not merely costlier or inconvenient.
- Notification Requirement: The affected party must formally inform the other party immediately.
- Mitigation Obligation: The invoking party must show reasonable efforts to minimize impact and fulfill obligations.
Significance
- Protects against legal and financial risks during unexpected disruptions.
- Widely used in oil, gas, and LNG contracts, especially during geopolitical instability.
- Provides a structured mechanism to manage contractual uncertainty and reduce disputes.
- Enhances predictability in international trade and commerce.
