BharatNotes
Overview
The polar regions — the Arctic and Antarctic — have emerged as critical arenas of geopolitical competition in the 21st century. Melting ice caps are opening new shipping routes (Northern Sea Route), exposing vast mineral and energy reserves, and raising sovereignty disputes. Meanwhile, territorial disputes and international boundary lines remain perennial topics for UPSC — from the South China Sea's nine-dash line to the Durand Line and McMahon Line affecting India's neighbourhood.
Exam Strategy: For Prelims, memorise the Arctic Council's 8 members, India's polar research stations (Maitri, Bharati, Himadri), the Antarctic Treaty year (1959), and international boundary lines. For Mains, focus on the geopolitics of the Northern Sea Route, Arctic resource competition, India's Arctic Policy (2022), and how UNCLOS governs maritime disputes.
The Arctic
Geography
| Feature | Details |
|---|---|
| Definition | Region around the North Pole, generally north of the Arctic Circle (66.5 degree N) |
| Ocean | Arctic Ocean — smallest and shallowest of the world's five oceans |
| Land masses | Parts of Russia, Canada, USA (Alaska), Norway, Denmark (Greenland), Finland, Sweden, Iceland |
| Permanent ice | Arctic sea ice is shrinking due to climate change; summer minimum extent has declined by ~13% per decade since 1979 |
| Indigenous peoples | Inuit, Sami, Nenets, Chukchi, and other Arctic-dwelling communities |
Arctic Council
The Arctic Council, established by the Ottawa Declaration in 1996, is the leading intergovernmental forum for Arctic cooperation.
| Category | Members |
|---|---|
| 8 Member States | Canada, Denmark (Greenland), Finland, Iceland, Norway, Russia, Sweden, United States |
| 6 Permanent Participants | Indigenous peoples' organisations (e.g., Inuit Circumpolar Council, Saami Council) |
| Observer States (13) | India, China, Japan, South Korea, Singapore, France, Germany, Italy, Netherlands, Poland, Spain, Switzerland, United Kingdom |
| India's observer status | Granted in 2013 at the Kiruna Ministerial Meeting |
Key Fact: All 8 Arctic Council member states have territory above the Arctic Circle. India gained observer status in 2013, joining China, Japan, South Korea, and Singapore (all also admitted in 2013). Observer states may attend meetings, propose projects, and contribute to working groups, but cannot vote.
Northern Sea Route (NSR)
| Feature | Details |
|---|---|
| Route | Along Russia's Arctic coast, connecting the Atlantic Ocean (via the Barents Sea) to the Pacific Ocean (via the Bering Strait) |
| Distance advantage | Mumbai to Rotterdam: ~7,400 nautical miles via NSR vs ~11,200 via Suez Canal (~34% shorter) |
| Strategic significance | Reduced shipping time, fuel costs, and avoidance of chokepoints (Suez Canal, Strait of Malacca) |
| Challenges | Ice coverage for much of the year, need for icebreaker escorts, limited port infrastructure, environmental risks |
| Russia's role | Controls most of the NSR; requires advance permission for transit; investing heavily in icebreaker fleet |
| Climate change impact | Arctic ice melt is making the NSR navigable for longer periods each year |
Arctic Resource Race
| Resource | Estimated Reserves | Key Claimants |
|---|---|---|
| Oil | ~13% of world's undiscovered oil (estimated 90 billion barrels) | Russia, USA, Canada, Norway |
| Natural Gas | ~30% of world's undiscovered gas | Russia (largest Arctic gas fields), Norway |
| Minerals | Rare earth elements, zinc, nickel, platinum, diamonds | Russia, Canada, Greenland (Denmark) |
| Fisheries | Rich fishing grounds as ice retreats | All Arctic states |
UNCLOS and Arctic Claims
Under UNCLOS (United Nations Convention on the Law of the Sea), coastal states can claim:
- Territorial Sea — 12 nautical miles from baseline
- EEZ — 200 nautical miles (sovereign rights over resources)
- Extended Continental Shelf — beyond 200 nm if geological evidence supports it (under Article 76)
Russia, Canada, Denmark (via Greenland), and Norway have submitted claims to the UN Commission on the Limits of the Continental Shelf (CLCS) to extend their continental shelves in the Arctic, including claims to the Lomonosov Ridge (which Russia argues is an extension of the Siberian continental shelf).
The Antarctic
Geography
| Feature | Details |
|---|---|
| Location | Continent around the South Pole, south of 60 degree S latitude |
| Area | ~14.2 million sq km — fifth-largest continent |
| Ice coverage | ~98% covered by ice (average thickness ~2.16 km) |
| Significance | Contains ~70% of the world's fresh water (locked in ice); no permanent human population |
| Climate | Coldest, driest, and windiest continent; lowest recorded temperature: -89.2 degree C (Vostok Station, 1983) |
Antarctic Treaty System (ATS)
| Feature | Details |
|---|---|
| Antarctic Treaty | Signed on 1 December 1959 in Washington, D.C.; entered into force on 23 June 1961 |
| Original signatories | 12 nations (including USA, USSR, UK, France, Argentina, Australia, Chile, Japan, New Zealand, Norway, South Africa, Belgium) |
| Current parties | 56 nations (as of 2024) |
| Key provisions | Antarctica to be used for peaceful purposes only; freedom of scientific investigation; no military activity, nuclear explosions, or nuclear waste disposal; territorial claims frozen |
| Consultative parties | 29 nations with voting rights (must demonstrate substantial scientific research activity); India is a Consultative Party |
Madrid Protocol (1991)
| Feature | Details |
|---|---|
| Full name | Protocol on Environmental Protection to the Antarctic Treaty |
| Signed | 1991 in Madrid; entered into force in 1998 |
| Key provision | Mining ban — prohibits all mineral resource activities in Antarctica (except scientific research) |
| Duration | Cannot be modified for 50 years from entry into force (i.e., until 2048) |
| Environmental protection | Designates Antarctica as a "natural reserve devoted to peace and science" |
| Environmental impact | All activities must undergo prior environmental impact assessment |
Exam Tip: The Madrid Protocol's mining ban is valid until at least 2048. After that, any modification requires agreement of three-quarters of the current Consultative Parties. This is a frequently tested fact — remember 1991 (signed) and 2048 (earliest review date).

Major Disputed Territories
South China Sea — Nine-Dash Line
| Feature | Details |
|---|---|
| What | China claims "historic rights" over most of the South China Sea, demarcated by the nine-dash line (originally eleven-dash line) |
| Claimants | China, Taiwan, Vietnam, Philippines, Malaysia, Brunei |
| Key features | Spratly Islands, Paracel Islands, Scarborough Shoal |
| Strategic importance | ~$3.4 trillion in trade passes through annually; rich fisheries; potential oil and gas reserves |
| 2016 Arbitration | The Permanent Court of Arbitration (The Hague) ruled that China's nine-dash line has no legal basis under UNCLOS; China rejected the ruling |
| UNCLOS relevance | The ruling affirmed that maritime entitlements are based on UNCLOS, not historical claims |
Other Major Disputed Territories
| Dispute | Between | Key Details |
|---|---|---|
| Crimea | Russia vs Ukraine | Annexed by Russia in 2014; internationally recognised as part of Ukraine by most countries |
| Kashmir | India vs Pakistan vs China | India claims entire J&K; Pakistan controls Pakistan-occupied Kashmir (PoK); China controls Aksai Chin |
| Falkland Islands | UK vs Argentina | UK controls; Argentina claims sovereignty; 1982 Falklands War; known as Islas Malvinas in Argentina |
| Kuril Islands | Russia vs Japan | Controlled by Russia since 1945; Japan claims the four southernmost islands (Northern Territories) |
| Golan Heights | Israel vs Syria | Captured by Israel in 1967 Six-Day War; annexed in 1981; US recognised Israeli sovereignty in 2019 |
| Western Sahara | Morocco vs Sahrawi Arab Democratic Republic (Polisario Front) | Morocco controls most of the territory; UN considers it a non-self-governing territory |
| Senkaku/Diaoyu Islands | Japan vs China vs Taiwan | Administered by Japan; claimed by China and Taiwan; uninhabited rocky islands in the East China Sea |
| Taiwan Strait | China vs Taiwan | China considers Taiwan a breakaway province; Taiwan functions as independent state; major US-China tension point |
Important International Boundary Lines
| Boundary Line | Between | Key Details |
|---|---|---|
| Durand Line | Afghanistan – Pakistan | Drawn in 1893 by Sir Mortimer Durand; 2,640 km; Afghanistan does not recognise it as an official international boundary |
| McMahon Line | India – China (in Arunachal Pradesh) | Proposed by Sir Henry McMahon at the Shimla Conference in 1914; China does not accept it; basis of the India-China border dispute in the eastern sector |
| Radcliffe Line | India – Pakistan (and India – Bangladesh) | Drawn by Sir Cyril Radcliffe in 1947 for the partition of British India into India and Pakistan (West and East) |
| Line of Control (LoC) | India – Pakistan (Kashmir) | De facto border in Kashmir since the Simla Agreement of 1972; not an internationally recognised boundary |
| Line of Actual Control (LAC) | India – China | De facto border; approximately 3,488 km; not clearly demarcated; source of frequent standoffs (Doklam 2017, Galwan 2020) |
| 38th Parallel | North Korea – South Korea | Divided Korea after WWII (1945); de facto border after the Korean War (1950–53); Demilitarised Zone (DMZ) runs roughly along it |
| 49th Parallel | USA – Canada (western border) | Agreed in 1818 (Convention of 1818); one of the world's longest undefended international borders |
| 17th Parallel | Formerly North Vietnam – South Vietnam | Divided Vietnam after the Geneva Accords (1954); reunified in 1975 after the Vietnam War |
| Maginot Line | France – Germany | French fortification line built in the 1930s along the Franco-German border; bypassed by Germany in WWII via Belgium |
| Oder-Neisse Line | Germany – Poland | Post-WWII border established in 1945; defines Germany's eastern boundary with Poland |
| Hindenburg Line | Germany – France (WWI) | German defensive position in WWI (1917); also refers to the ceasefire line between India and Pakistan before 1972 (now LoC) |
Prelims Tip: Do not confuse these boundary lines — Durand Line (Afghanistan-Pakistan, 1893), McMahon Line (India-China, 1914), Radcliffe Line (India-Pakistan partition, 1947). The LAC (India-China) is distinct from the McMahon Line — the LAC is the de facto border across the entire India-China frontier, while the McMahon Line specifically refers to the eastern sector (Arunachal Pradesh).
UNCLOS — Key Provisions for Boundary Disputes
| Zone | Distance from Baseline | Rights |
|---|---|---|
| Territorial Sea | 0–12 nautical miles | Full sovereignty; innocent passage allowed for foreign ships |
| Contiguous Zone | 12–24 nautical miles | Enforcement of customs, fiscal, immigration, and sanitary laws |
| Exclusive Economic Zone (EEZ) | 0–200 nautical miles | Sovereign rights over natural resources (fishing, mining, energy); freedom of navigation for all states |
| Continental Shelf | Up to 200 nm (extendable under Article 76) | Sovereign rights over seabed and subsoil resources |
| High Seas | Beyond 200 nm (or extended shelf) | Freedom of navigation, fishing, scientific research; no state sovereignty |
Article 76 allows coastal states to claim an Extended Continental Shelf beyond 200 nm if they can prove the seabed is a natural prolongation of their land territory. This is the basis of Russia's Arctic claim over the Lomonosov Ridge and overlapping claims in the Arctic Ocean.

Global Strategic Chokepoints
Understanding maritime chokepoints is essential for geopolitics — control over these narrow passages confers immense strategic leverage.
| Chokepoint | Location | Connects | Strategic Significance |
|---|---|---|---|
| Strait of Hormuz | Between Iran and Oman/UAE | Persian Gulf to Gulf of Oman | ~20% of world's oil passes through; vital for energy security |
| Strait of Malacca | Between Malaysia, Singapore, and Indonesia | Indian Ocean to Pacific Ocean | ~25% of global trade; India's energy imports route |
| Suez Canal | Egypt | Mediterranean Sea to Red Sea | ~12% of global trade; opened 1869; expanded 2015 |
| Panama Canal | Panama | Atlantic Ocean to Pacific Ocean | ~5% of global trade; avoids circumnavigating South America |
| Bab-el-Mandeb | Between Yemen and Djibouti | Red Sea to Gulf of Aden | Key route between Asia and Europe via Suez; Houthi disruptions (2024–25) |
| Turkish Straits | Turkey (Bosphorus + Dardanelles) | Black Sea to Mediterranean Sea | Russia's only warm-water naval access to the Mediterranean |
| Strait of Gibraltar | Between Spain and Morocco | Atlantic Ocean to Mediterranean Sea | Controls entry to the Mediterranean |
Mains Relevance: India's energy security depends heavily on the Strait of Hormuz (~80% of India's crude oil imports transit through it) and the Strait of Malacca (key route for trade with East and Southeast Asia). The opening of the Northern Sea Route could reduce India's dependence on these chokepoints, which is why India's Arctic Policy (2022) emphasises NSR potential.
Climate Change and Polar Regions
| Impact | Arctic | Antarctic |
|---|---|---|
| Ice loss | Arctic sea ice declining ~13% per decade (summer minimum); 2012 and 2020 saw record lows | Antarctic ice sheet losing ~150 billion tonnes per year; West Antarctic Ice Sheet most vulnerable |
| Sea level rise | Arctic ice melt contributes minimally (floating ice); Greenland ice sheet melt is significant | Antarctic ice sheet holds enough ice to raise sea level by ~58 metres if fully melted |
| Permafrost thaw | Releases methane (potent greenhouse gas); threatens infrastructure in Arctic regions | Limited permafrost; not a major concern |
| Biodiversity | Polar bears, walruses, Arctic foxes threatened by habitat loss | Penguin colonies, krill populations affected by changing ice patterns |
| Geopolitical shift | New shipping routes (NSR, Northwest Passage); resource access; sovereignty disputes intensify | Relatively stable under Antarctic Treaty; concern about post-2048 mining pressure |
