Natural Resource Classification

Natural resources are materials and components that can be obtained from the natural environment and used to support human life and economic activity.

Classification by Renewability

Type Definition Examples
Renewable Replenish naturally in human timescales Solar energy, wind, water (flowing), biomass, forests (if managed)
Non-renewable Form over geological timescales; stock resources Fossil fuels (coal, oil, natural gas), metal ores, rare earths
Inexhaustible Virtually unlimited Solar radiation, wind, tidal energy

Classification by Origin

Type Examples
Biotic (Organic) Forests, fisheries, wildlife, fossil fuels (organic origin)
Abiotic (Inorganic) Water, soils, minerals, metal ores, rocks

Oil Geography — The World's Most Strategic Resource

Petroleum (crude oil) remains the single most traded commodity by value. Its distribution is highly uneven — creating economic and geopolitical dependencies.

Global Oil Reserves Distribution

Country/Region Approximate Share of Proven Reserves Notes
Venezuela ~17% Largest proven reserves globally (Orinoco Belt — heavy oil)
Saudi Arabia ~17% Ghawar field — world's largest conventional oil field
Iran ~9% Third largest; under heavy sanctions
Iraq ~8% Major OPEC producer; Rumaila field
UAE ~7% Abu Dhabi holds bulk of UAE reserves
Russia ~6% World-scale production but large domestic consumption
Kuwait ~6% Burgan field — second largest conventional oil field
USA ~4% (conventional) Shale revolution transformed production; world's #1 producer by volume
Canada ~10% Oil sands (Alberta) — non-conventional, expensive to extract

The Middle East Dominance

The Persian Gulf region holds over 50% of global proven oil reserves. The strategic importance of the Strait of Hormuz (between Oman and Iran) cannot be overstated:

  • Approximately 20% of global oil trade passes through the Strait of Hormuz daily
  • Any closure would cause immediate global price spikes
  • India imports ~85% of its oil needs; ~65% comes from the Middle East/Persian Gulf

The US Shale Revolution

Hydraulic fracturing (fracking) technology transformed US oil production from ~5 mbpd (2008) to over 13 mbpd (2023) — making the USA the world's largest oil producer, overtaking Saudi Arabia and Russia. This reduced US dependence on Middle Eastern oil but created new environmental controversies (groundwater contamination, methane leakage).


OPEC and OPEC+

OPEC (Organization of the Petroleum Exporting Countries)

Founded in 1960 (Baghdad); headquarters in Vienna, Austria.

Current 12 member countries (as of 2024–25): Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, UAE, Venezuela.

Note: Ecuador, Qatar, and Indonesia have left OPEC at various times. Gabon has rejoined.

OPEC+

OPEC+ is a broader coalition formed in 2016 that includes OPEC members plus major non-OPEC oil producers. Key non-OPEC members: Russia, Kazakhstan, Azerbaijan, Mexico, Oman.

  • OPEC+ collectively accounts for approximately 47% of global crude oil production (2024)
  • Russia was the largest crude oil producer in OPEC+ in 2024, averaging 9.2 million b/d
  • Saudi Arabia produced approximately 9.0 million b/d in 2024

Production quotas and price politics: OPEC+ manages production quotas to influence global oil prices. When prices fall too low, they cut production (supply restriction). When prices rise too high, they may increase supply.


Natural Gas Geography

Natural gas is the cleanest fossil fuel and is central to the energy transition (as a bridging fuel). Its geography is distinct from oil due to transportation challenges — gas requires pipelines or liquefaction into LNG (Liquefied Natural Gas).

Key Gas Producers

Country Type Notes
USA Pipeline + LNG (shale gas) World's largest gas producer; growing LNG exporter
Russia Pipeline-dominant Nordstream pipeline (Europe); now pivoting to Asia
Iran LNG-limited 2nd largest reserves globally; sanctions limit exports
Qatar LNG-dominant World's largest LNG exporter per capita; North Field (world's largest gas field)
Australia LNG Major exporter to Japan, China, South Korea
Turkmenistan Pipeline Central Asia's giant; Galkynysh field

Pipeline Politics

  • Nord Stream (Russia–Germany): Pipelines that carried Russian gas to Europe; Nord Stream 2 was suspended after Russia's Ukraine invasion (February 2022); Nord Stream 1 and 2 were sabotaged (September 2022) in a still-unresolved act of infrastructure warfare
  • Central Asian pipelines: Competition between Russia, China, and Turkey over pipeline routes from Central Asia
  • India's interest: Iran-Pakistan-India (IPI) pipeline repeatedly stalled; TAPI (Turkmenistan-Afghanistan-Pakistan-India) pipeline — security concerns

Coal Distribution

Coal remains the world's largest source of electricity generation. It is the most abundant fossil fuel.

Global Coal Geography

Country Role Notes
China #1 producer AND consumer Produces ~50% of world's coal; dominates global coal market; also largest importer
India #2 producer; #2 consumer Coal provides ~70% of India's electricity; largely self-sufficient in thermal coal
USA Declining producer Once world's #1; declining due to cheap gas and renewables
Australia Major exporter Metallurgical coal for steelmaking; thermal coal to Asia
Indonesia Major exporter World's #1 coal exporter by volume; thermal coal
Russia Major exporter Redirecting to Asia after European market loss

India's Coal Geography

India has approximately 5th-largest coal reserves in the world. Key coalfields:

Coalfield State Type Notes
Jharia Jharkhand Bituminous Best quality coking coal; underground fires ongoing
Raniganj West Bengal Bituminous Oldest coalfield; Damodar Valley region
Singrauli MP/UP border Thermal "Energy capital" of India; huge open cast mines
Korba Chhattisgarh Thermal Important for power generation
Talcher Odisha Thermal Mahanadi coalfields
North-East coalfields Assam, Meghalaya Sub-bituminous/lignite Rat-hole mining controversy in Meghalaya (NGT banned)

Most Indian coal belongs to the Gondwana geological system (Permian age, ~250–300 million years old) and is found in the Damodar, Son, Mahanadi river valleys — collectively called the Gondwana coalfields.


Critical Minerals — The New Geopolitics

Critical minerals are those whose supply is economically important but whose supply chain is concentrated, fragile, or controlled by few countries — making them a strategic concern for the clean energy transition and advanced manufacturing.

Definition

The International Energy Agency (IEA) defines critical minerals as those where supply concentration risks are high and substitution is difficult. Examples: lithium, cobalt, nickel, rare earth elements, gallium, germanium, graphite, manganese.

Lithium — The "White Gold"

Lithium is essential for lithium-ion batteries powering electric vehicles, smartphones, and grid storage.

The Lithium Triangle (Chile–Argentina–Bolivia):

  • Together these three countries hold over 56% of global known lithium reserves
  • Bolivia alone: ~21 million tonnes (largest share but least production due to political issues)
  • Argentina: ~19.3 million tonnes (growing production)
  • Chile: ~9.6 million tonnes (was dominant exporter; ~49,000 tonnes produced in 2024)
  • Australia is the world's largest lithium producer by volume (spodumene ore, not brine)
  • China dominates lithium processing and battery manufacture

Cobalt — DRC's Near-Monopoly

Cobalt is a key component of high-energy-density lithium-ion batteries (NMC chemistry).

  • DRC (Democratic Republic of Congo) holds approximately 52.8% of global cobalt reserves and accounts for over 70% of global cobalt mine production (2023)
  • The DRC concentration raises serious ethical concerns: child labour, conflict financing, and environmental damage in Katanga/Kasai provinces
  • China dominates cobalt refining — controlling well over half of global refining capacity

Rare Earth Elements (REEs)

17 elements including lanthanum, cerium, neodymium, praseodymium, dysprosium, terbium — essential for permanent magnets (electric motors, wind turbines), phosphors (LEDs), and catalysts.

  • China produces approximately 70% of global rare earth mining output and controls ~91% of global REE separation and refining
  • China imposed REE export restrictions in 2010 (Japan dispute), 2023 (gallium, germanium), and 2024–25 (additional critical minerals) — demonstrating the strategic leverage
  • Alternative sources: Australia (Mount Weld), USA (Mountain Pass), Greenland, India (Beach sand minerals — Kerala, Tamil Nadu, Odisha)
  • India has significant deposits of thorium (monazite sands), and some REE deposits through beach sand minerals

Nickel, Gallium, Germanium

Mineral Key Producer Use
Nickel Indonesia (#1, ~50% of global production), Philippines, Russia EV batteries (NMC chemistry), stainless steel
Gallium China (~80%) Semiconductors, LEDs, 5G chips
Germanium China (~60%) Fibre optics, infrared optics, semiconductors
Graphite China (~70%+ of natural graphite) Lithium-ion battery anodes

India's Critical Minerals Strategy

In 2023, India's Ministry of Mines released a list of 30 critical minerals including: Antimony, Beryllium, Bismuth, Cobalt, Copper, Gallium, Germanium, Graphite, Hafnium, Indium, Lithium, Molybdenum, Niobium, Nickel, PGE (Platinum Group Elements), Phosphorous, Potash, REE, Rhenium, Silicon, Strontium, Tantalum, Tellurium, Tin, Titanium, Tungsten, Vanadium, Zirconium, Selenium, and Cadmium.

Key Initiatives

Initiative Details
National Critical Mineral Mission (NCMM) Launched January 2025; 7-year mission (2024–25 to 2030–31); ₹16,300 crore proposed expenditure
KABIL (Khanij Bidesh India Ltd.) JV of NALCO, HCL, and MECL; acquires overseas mineral assets; signed $24 million deal with Argentina (January 2024) for 5 lithium blocks in Catamarca province
MMDR Amendment 2023 Central government authority to auction critical mineral blocks; 4 tranches of auction in 2023–24
Bilateral deals Partnerships with Australia, Argentina, Chile, DRC for mineral supply security

Global Water Resources

Freshwater Distribution

  • Total water on Earth: ~1.4 billion cubic km
  • Freshwater: Only ~2.5% of total water
  • Of that freshwater: ~68.7% in glaciers and ice caps, ~30.1% in groundwater, only ~0.3% in rivers and lakes
  • Conclusion: Accessible surface freshwater is extremely scarce — rivers and lakes hold only 0.0075% of all Earth's water

Water Stress — Global Hotspots

Region Situation
Middle East & North Africa (MENA) Most water-stressed region globally; many countries below 500 m³/person/year (absolute scarcity)
Sub-Saharan Africa Large parts face chronic water stress
Central Asia Aral Sea disaster (Soviet irrigation policy); Amu Darya/Syr Darya over-extraction
South Asia (incl. India) NITI Aayog Composite Water Management Index (2018) warned of severe water crisis — 21 Indian cities facing groundwater exhaustion by 2020 (target; now updated)
China's North China Plain Severe groundwater depletion; Beijing faces water stress

India's Water Stress

NITI Aayog's Water Management Index highlighted:

  • 600 million Indians face high–extreme water stress
  • India is the world's largest user of groundwater — extracts more than USA and China combined
  • Key drivers: paddy cultivation, sugarcane, inefficient irrigation (only 40% irrigation efficiency)

Forest Resources — Global Distribution

Forest Type/Region Location Status
Amazon Rainforest Brazil, Peru, Colombia, Venezuela ~5.5 million sq km; "lungs of the Earth"; deforestation at ~11,000 sq km/year (Brazil 2022)
Congo Basin DRC, Congo, Cameroon, CAR 2nd largest tropical forest; relatively intact but rising pressure
Southeast Asian Forests Indonesia, Malaysia, Myanmar High deforestation for palm oil, rubber, pulp; critical biodiversity hotspots
Boreal Forest (Taiga) Russia, Canada, Scandinavia Largest forest biome; permafrost stores massive carbon
India 25.17% forest/tree cover (ISFR 2023) 33% target under National Forest Policy 1988

Marine Resources and Fishing Geography

  • World capture fisheries production: ~80 million tonnes/year (plateauing since 1990s)
  • Top fishing nations: China (#1 by far), Indonesia, Peru, India, USA, Russia
  • Exclusive Economic Zones (EEZ): Under UNCLOS 1982, coastal states have sovereign rights over living and non-living resources within 200 nautical miles — creating a vast national resource space
  • India's EEZ: ~2.02 million sq km in Indian Ocean
  • High Seas Treaty (BBNJ, 2023/2026): Extends governance framework to the high seas (beyond EEZ)

Resource Curse — The Paradox of Plenty

The Resource Curse (also called Dutch Disease) describes the paradox where resource-rich nations (especially oil and minerals) often experience slower economic development, poor governance, and conflict compared to less resource-endowed nations.

Mechanism:

  1. Resource boom increases foreign currency inflows
  2. Local currency appreciates (Dutch Disease) — making manufacturing and agriculture less competitive
  3. Revenue volatility from commodity price cycles; poor long-term planning
  4. Elite capture of resource rents; corruption; weak institutions

Examples: Nigeria (oil), DRC (minerals), Venezuela (oil), Angola (oil). Compare with resource-poor success stories: South Korea, Singapore, Japan.

Conflict Minerals: The Kimberley Process (2003) — international certification scheme to prevent "blood diamonds" (conflict diamonds from war zones in Africa) from entering mainstream diamond trade.


China's Belt and Road Initiative — Resource Access Dimension

China's Belt and Road Initiative (BRI), launched in 2013, has a significant resource-access dimension:

  • Investments in mining infrastructure in DRC (cobalt), Zambia (copper), Pakistan (CPEC — energy), Myanmar (oil pipeline)
  • Gives China preferential access to raw materials and ports (String of Pearls in IOR)
  • BRI debt-trap criticism: countries taking Chinese loans for infrastructure may lose strategic assets (Hambantota port, Sri Lanka — 99-year lease to China)
  • India has not joined BRI, citing sovereignty concerns (CPEC passes through Pakistan-occupied Kashmir)

India's Resource Security Strategy

Dimension Strategy
Energy security Diversification of oil imports (Middle East, Russia, USA, Africa); strategic petroleum reserves (Visakhapatnam, Mangalore, Padur); renewable energy expansion to 500 GW by 2030
Indian Ocean Region (IOR) SAGAR (Security and Growth for All in the Region) doctrine; IORA membership; Blue Economy
Critical minerals NCMM 2025; KABIL overseas acquisitions; bilateral deals; MMDR amendments
Food and water National Water Mission; PM Krishi Sinchayee Yojana (Har Khet Ko Pani); buffer stocks
Strategic partnerships iCET (USA–India tech; minerals supply chain); Minerals Security Partnership (MSP); Quad (critical technology and supply chains)

Global Oil & Gas — Production and Benchmark Data

Top Oil-Producing Countries

Rank Country Production (million barrels/day) Share of Global Output
1 United States 13.58 ~16%
2 Russia 9.87 ~12%
3 Saudi Arabia 9.51 ~11%
4 Canada 4.94 ~6%
5 Iraq 4.39 ~5%
6 China 4.34 ~5%
7 Iran 4.19 ~5%
8 UAE 3.82 ~4.5%
9 Brazil ~3.4 ~4%
10 Kuwait 2.58 ~3%

The top three producers — the USA, Russia, and Saudi Arabia — together account for about 39% of global crude oil production.

Top Proven Oil Reserves

Rank Country Proven Reserves (billion barrels)
1 Venezuela ~303
2 Saudi Arabia ~267
3 Iran ~209
4 Canada ~164
5 Iraq ~145

Venezuela holds the world's largest proven reserves, but most of its oil is heavy crude (Orinoco Belt), which is expensive to extract. Saudi Arabia's reserves are lighter crude located close to the surface, making extraction far more cost-effective.

Oil Price Benchmarks

  • Brent Crude — Extracted from the North Sea; the benchmark for approximately two-thirds of globally traded crude oil. Used to price oil from Europe, Africa, and the Middle East.
  • West Texas Intermediate (WTI) — Extracted in the USA; the benchmark for North American oil. Traded on the New York Mercantile Exchange (NYMEX).
  • Dubai/Oman Crude — The benchmark for oil exported to Asia from the Persian Gulf.

India's Oil Import Dependence

India's crude oil import dependence climbed to approximately 88.6% during the April-January period of FY 2025-26. India surpassed China in 2024 as the world's largest oil demand growth driver.

Major suppliers to India (2025): Russia (~31.5%), Iraq, Saudi Arabia, UAE, USA, and Kuwait. Domestic production meets only about 11% of India's petroleum requirements, down from ~19% in 2014-15.


Global Coal Reserves and Coal Types

Top Coal Reserves (Proven)

Rank Country Reserves (billion tonnes) Share of Global Reserves
1 United States 273.2 ~23%
2 Russia 178.8 ~15%
3 China 173.1 ~13%
4 Australia 164.8 ~14%
5 India 140.8 ~10%

These five nations control approximately 76% of the world's coal reserves. Australia alone accounts for about one-third of global coal exports. Coal trade flows primarily from the Southern Hemisphere (Australia, Indonesia, South Africa) to consuming economies in Asia.

Types of Coal

Type Carbon Content Calorific Value Uses
Anthracite 86-97% Highest Domestic heating, metallurgy
Bituminous 45-86% High Power generation, steel-making (coking coal)
Sub-bituminous 35-45% Moderate Power generation
Lignite 25-35% Lowest Power generation (pit-head thermal plants)

Rare Earth Elements — Detailed Profile

What Are REEs?

Rare earth elements are a group of 17 metallic elements — the 15 lanthanides (lanthanum to lutetium) plus scandium and yttrium. Despite their name, they are not exceptionally rare in the Earth's crust but are rarely found in concentrated, economically exploitable deposits.

Applications

  • Permanent magnets (neodymium, praseodymium) — electric vehicles (EVs), wind turbines, hard drives
  • Defence — precision-guided munitions, jet engines, night-vision goggles, radar systems
  • Electronics — smartphones, flat screens, fibre optics
  • Catalysts — petroleum refining, automobile catalytic converters (cerium, lanthanum)
  • Phosphors — LED lighting, display screens (europium, terbium)

China's Dominance

Stage China's Share (approx.)
Mining ~69-70% (2023-24)
Processing/Refining ~90-91%
Permanent magnet production ~90-94%

China's 2025 production quota was set at 270,000 tonnes of rare earth oxide equivalent. The USA is the second-largest producer (~12%), followed by Myanmar (~11%). By 2030, the IEA projects China will still control about 51% of REE mining and 76% of refining.

India's Rare Earth Reserves

India holds the world's third-largest rare earth reserves — approximately 8% of global reserves — but contributes less than 1% of global REE mining output. India has 13.15 million tonnes of monazite containing an estimated 7.23 million tonnes of rare earth oxides. Deposits are found primarily in coastal beach sands of Odisha, Kerala, Andhra Pradesh, and Tamil Nadu. IREL (India) Ltd., under the Department of Atomic Energy, is the nodal agency for rare earth production. In November 2025, the government approved a Rs 7,280 crore scheme to develop 6,000 MTPA of integrated rare earth permanent magnet manufacturing capacity.


Strategic Straits of the World

Straits are narrow waterways connecting two larger bodies of water. They are of immense geopolitical and economic significance as chokepoints for global maritime trade.

Key Straits at a Glance

Strait Connects Width (narrowest) Key Significance
Strait of Hormuz Persian Gulf - Gulf of Oman ~39 km (navigable: ~6 nmi) ~20% of global petroleum liquids; world's most critical oil chokepoint
Strait of Malacca Indian Ocean - Pacific Ocean (South China Sea) ~2.7 km (near Singapore) 25-30% of global maritime trade; over 100,000 vessels/year
Bab-el-Mandeb Red Sea - Gulf of Aden ~26 km Gateway to Suez Canal; critical for Europe-Asia trade
Strait of Gibraltar Atlantic Ocean - Mediterranean Sea ~14.4 km Links Atlantic to Mediterranean; Europe-Africa boundary
Sunda Strait Java Sea - Indian Ocean ~24 km Alternative to Malacca for deep-draught vessels
Lombok Strait Bali Sea - Indian Ocean ~20 km Deep-water route for supertankers; alternative to Malacca
Taiwan Strait South China Sea - East China Sea ~130 km (narrowest) Politically sensitive; major shipping route; US-China flashpoint
Palk Strait Bay of Bengal - Gulf of Mannar ~64 km India-Sri Lanka; shallow waters, mainly fishing traffic
Bosphorus Black Sea - Sea of Marmara ~700 m Links Black Sea to Mediterranean via Marmara; bisects Istanbul
Dardanelles Sea of Marmara - Aegean Sea ~1.2 km Part of Turkish Straits; governed by Montreux Convention (1936)

Strait of Hormuz — In Detail

Located between Iran (north) and Oman/UAE (south), the Strait of Hormuz is the world's most important oil transit chokepoint. In 2024, approximately 20 million barrels per day of crude oil and petroleum liquids — about 20% of global petroleum liquids consumption — passed through it. It also handles roughly 20% of global LNG trade (primarily Qatari LNG).

The navigable channel is extremely narrow: two 2-nautical-mile-wide shipping lanes (one inbound, one outbound) separated by a 2-mile buffer zone, giving a total navigable width of only about 6 nautical miles. Any disruption here would cause an immediate global energy crisis.

Strait of Malacca — In Detail

Stretching approximately 900 km between the Malay Peninsula and Sumatra, the Strait of Malacca is the shortest sea route between the Indian Ocean and the Pacific Ocean. Over 100,000 vessels transit annually, carrying goods worth approximately $5 trillion. About 35% of oil transported by sea and 20% of gas pass through it.

At its narrowest point near Singapore, the strait contracts to just 2.7 km. Its shallow depth (~25 m in parts) restricts supertanker passage, pushing them to alternative routes through the Lombok or Sunda Straits.

Turkish Straits (Bosphorus + Dardanelles)

The Bosphorus is approximately 31 km long (700 m to 3.3 km wide). The Dardanelles is 61 km long (1.2 to 6 km wide). Together, they form the only maritime passage from the Black Sea to the Mediterranean.

The Montreux Convention (1936) governs transit through the Turkish Straits, granting Turkey sovereign control while ensuring freedom of navigation for merchant vessels. Warship passage is subject to restrictions, especially for non-Black Sea nations.


Major Canals

Suez Canal

Feature Details
Location Egypt; connects Mediterranean Sea to Red Sea
Opened 17 November 1869
Length 193.3 km (120 miles)
Locks None (sea-level canal)
Trade share ~12-15% of global trade; ~30% of global container traffic

The Suez Canal reduces the Europe-Asia maritime distance by approximately 8,900 km compared to the Cape of Good Hope route. About 19,000+ vessels transit annually.

2021 Ever Given Blockage: On 23 March 2021, the container ship Ever Given ran aground and blocked the canal for 6 days (freed 29 March). Over 400 vessels were delayed; global trade was disrupted by an estimated $9.6 billion per day.

Panama Canal

Feature Details
Location Panama; connects Atlantic Ocean to Pacific Ocean
Opened 15 August 1914
Length ~82 km (51 miles)
Expanded locks (2016) 55 m wide, 430 m long, 18 m deep
Trade share ~5-6% of global maritime trade

The canal uses a system of locks to raise and lower ships through the continental divide. The 2016 expansion (inaugurated 26 June 2016) added a third set of larger locks, allowing New Panamax vessels to transit — increasing the share of cargo vessels that can use the canal from 45% to approximately 79%.

Kiel Canal

Located in Germany; connects North Sea to Baltic Sea; opened 1895; 98 km long. Reduces the North Sea-Baltic Sea journey by approximately 460 km by bypassing the Jutland Peninsula. About 32,000 ships transit annually.


Contested Borders and Territorial Disputes

South China Sea

China claims sovereignty over most of the South China Sea via its nine-dash line, overlapping with the EEZs of the Philippines, Vietnam, Malaysia, Brunei, and Indonesia. In July 2016, the Permanent Court of Arbitration (under UNCLOS) ruled in favour of the Philippines, declaring that China's historic rights claims within the nine-dash line have no lawful effect. China rejected the ruling as "null and void" and has continued island-building and militarisation in the Spratly and Paracel Islands.

India-China LAC Disputes

  • Aksai Chin — Administered by China, claimed by India as part of Ladakh. China built National Highway 219 through it in the 1950s, triggering the 1962 Sino-Indian War.
  • Arunachal Pradesh — Claimed by China as "South Tibet" (Zangnan). India administers it as a full state.
  • The Line of Actual Control (LAC) is approximately 3,488 km long with no mutually agreed delineation (Doklam 2017, Galwan Valley 2020).

Other Major Territorial Disputes

Dispute Parties Key Details
Kuril Islands Russia vs Japan Four southernmost islands seized by the USSR in 1945; prevents a Russia-Japan peace treaty
Crimea Russia vs Ukraine Annexed by Russia in 2014; recognised as Ukrainian territory by most nations
Golan Heights Israel vs Syria Captured by Israel in 1967; annexed 1981; US recognised Israeli sovereignty in 2019
Western Sahara Morocco vs Polisario Front Morocco controls most of the territory; Polisario seeks independence or referendum
Falkland/Malvinas Islands UK vs Argentina UK administers since 1833; Argentina claims sovereignty; 1982 Falklands War
Kashmir India vs Pakistan (and China) India administers J&K and Ladakh; Pakistan administers PoK; China holds Aksai Chin

Geopolitically Significant Seas and the Northern Sea Route

South China Sea

An area of approximately 3.5 million sq km through which an estimated $3-5 trillion in trade passes annually. Rich in fisheries and potentially large hydrocarbon reserves. Contested by China, Vietnam, the Philippines, Malaysia, Brunei, and Taiwan.

Caspian Sea

The world's largest enclosed inland body of water, bordered by Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. The 2018 Convention on the Legal Status of the Caspian Sea resolved decades of disputes — it is classified as neither a sea nor a lake but given a special legal status.

Arctic Ocean and the Northern Sea Route

As Arctic sea ice melts due to climate change, the Northern Sea Route (NSR) along Russia's northern coast is becoming increasingly navigable, potentially reducing the Europe-Asia shipping distance by up to 40% compared to the Suez Canal route. Arctic resources — an estimated 13% of undiscovered global oil and 30% of undiscovered gas reserves lie beneath the Arctic. Russia has 47+ nuclear and diesel icebreakers in service.


Major Rivers of the World

River Length (km) Continent Countries/Regions Key Significance
Nile ~7,088 Africa 11 countries (Burundi, DRC, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania, Uganda) Traditionally considered world's longest river; lifeline of Egypt; GERD dispute
Amazon ~6,400 South America Peru, Colombia, Brazil Largest river by discharge volume; drains world's largest rainforest
Yangtze ~6,300 Asia China Longest river in Asia; Three Gorges Dam (world's largest hydropower station)
Mississippi-Missouri ~6,275 (system) North America USA Largest river system in North America; major inland waterway
Congo ~4,700 Africa DRC, Republic of Congo World's deepest river (up to ~220 m); second-largest by discharge
Danube ~2,850 Europe 10 countries Second-longest European river; passes through 4 national capitals (Vienna, Bratislava, Budapest, Belgrade)

Water Geopolitics

Nile Dispute — GERD (Grand Ethiopian Renaissance Dam)

  • GERD: Grand Ethiopian Renaissance Dam on the Blue Nile in Ethiopia — Africa's largest hydroelectric project (~5,150 MW capacity); construction substantially completed
  • Dispute: Ethiopia (upstream) vs Egypt (downstream) vs Sudan (midstream)
  • Egypt's position: The Nile provides ~90% of Egypt's freshwater; claims historical rights under 1929 and 1959 treaties (which Ethiopia rejects as colonial-era)
  • Ethiopia's position: Sovereign right to develop its own natural resources; dam provides electricity to millions
  • Status (2024): No binding agreement reached despite years of African Union-mediated talks; GERD is operational and filling continues

Mekong River — China's Dam Diplomacy

  • Mekong: Originates in Tibetan Plateau (as Lancang River in China); flows through Yunnan, Myanmar, Laos, Thailand, Cambodia, Vietnam
  • China's dams: China has built 11 large mainstream dams on the upper Mekong (Lancang)
  • Impact: Downstream countries report reduced water flow, disrupted fish migration, altered sedimentation — threatening food security and livelihoods of ~60 million people
  • Mekong River Commission (MRC): Established 1995; China is only a "dialogue partner" — limits effectiveness

India's Water Diplomacy

  • Indus Waters Treaty (1960): India-Pakistan; World Bank brokered; India gets Ravi, Beas, Sutlej; Pakistan gets Indus, Jhelum, Chenab. India notified Pakistan of intent to modify the treaty in 2023 amid broader tensions
  • Brahmaputra/Yarlung Tsangpo: No treaty with China; China's dam-building on upper reaches causes concern in India (flood surges, diversion fears)
  • Bangladesh: Farakka Barrage dispute; 1996 Ganga Water Treaty; Teesta River — pending treaty since 2011 (blocked by West Bengal)

Food Geopolitics

Ukraine-Russia War and Global Food Security

  • Ukraine and Russia together account for ~30% of global wheat exports and ~60% of global sunflower oil exports
  • Russia's 2022 invasion disrupted Black Sea grain shipments, triggering a global food crisis
  • Impact: Food import-dependent countries in Africa and the Middle East (Egypt, Sudan, Somalia, Libya) faced severe food inflation; FAO Food Price Index hit record highs in March 2022
  • Black Sea Grain Initiative: UN-brokered deal (July 2022) allowed grain exports from Ukraine; Russia withdrew in July 2023 — renewed disruption

Arctic Resources and Sovereignty

  • Why the Arctic matters: Estimated to hold ~30% of world's undiscovered natural gas and ~13% of undiscovered oil (USGS assessment); also rare earth deposits, fisheries, and new shipping routes
  • Arctic sea ice retreat: Climate change is opening the Northern Sea Route — cutting shipping distance from Asia to Europe by ~40% compared to Suez Canal route
  • Claims and tensions: Arctic Council (8 members — USA, Russia, Canada, Norway, Denmark, Iceland, Finland, Sweden); Russia has the longest Arctic coastline and has aggressively asserted claims; NATO Arctic members have increased military presence
  • India's Arctic Policy: Released in 2022 — India has a research station (Himadri) at Svalbard, Norway; interests in research, shipping routes, and resource access

The Petrodollar System

Since the 1970s, most global oil trade has been denominated in US dollars — a system known as the petrodollar. This arrangement:

  • Supports global demand for the US dollar, reinforcing its status as the world's reserve currency
  • Gives the US outsized influence over global finance and the ability to impose sanctions
  • Is gradually being challenged: Saudi Arabia has begun accepting yuan for some oil sales to China; Russia prices its oil in rubles and yuan; BRICS nations discuss alternative payment mechanisms

US-China Tech War: Semiconductors and Rare Earths

The US-China technology rivalry has intensified resource competition:

  • The US has imposed export controls on advanced semiconductor chips and chip-making equipment to China (October 2022 onward)
  • China has retaliated with export restrictions on gallium, germanium (July 2023), and expanded controls on antimony and other critical minerals
  • Taiwan (TSMC) manufactures over 90% of the world's most advanced semiconductor chips — making the Taiwan Strait one of the most strategically significant waterways
  • Both nations are investing heavily in domestic rare earth and critical mineral supply chains to reduce dependency on the other

  2. The Strait of Hormuz is important because:

    • It is the passage through which approximately 20% of global oil trade passes
  3. With reference to natural gas, consider the following: 1. Qatar is one of the largest LNG exporters 2. Russia primarily exports gas through LNG tankers 3. Nord Stream pipeline connected Russia to Germany

    • Statements 1 and 3 are correct; 2 is incorrect (Russia is pipeline-dominant)
  4. India's "30 Critical Minerals" list was released by which ministry?

    • Ministry of Mines (2023)

Mains

  1. "The global scramble for critical minerals is the new geopolitical frontier." Examine this statement with reference to lithium, cobalt, and rare earth elements. How is India positioning itself in this competition? (GS3 — 15 marks)

  2. Analyse the geographical distribution of global oil and natural gas reserves. How has the US shale revolution changed global energy geopolitics? (GS1/GS3 — 15 marks)

  3. "The resource curse is not inevitable but reflects governance failures." Critically examine this view with reference to oil-rich nations in Africa and the Gulf. (GS1 — 10 marks)

  4. Discuss India's water stress challenge with reference to groundwater depletion, inter-state river disputes, and the NITI Aayog water index. What policy interventions are needed? (GS3 — 15 marks)


Exam Strategy

For Prelims:

  • OPEC members: 12 countries — Algeria, Congo, EG, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, UAE, Venezuela; founded 1960, headquartered in Vienna
  • Lithium Triangle: Chile, Argentina, Bolivia (in descending order of production); ~56% of global reserves in brine/salt flats (salars)
  • DRC cobalt: ~70-84% of global production; China refines most of it
  • China REE mining: ~69-70%; refining: ~91%
  • India's critical minerals list: 30 minerals (Ministry of Mines, 2023)
  • KABIL: JV of NALCO, HCL, and MECL under Ministry of Mines; lithium deal in Argentina (Catamarca province)
  • Strait of Hormuz: between Iran and Oman/UAE; ~20% of global petroleum liquids
  • Strait of Malacca: between Malay Peninsula and Sumatra; ~25-30% of global maritime trade
  • Bosphorus + Dardanelles = Turkish Straits; governed by Montreux Convention (1936)
  • Suez Canal: 1869, Egypt, no locks; reduces Europe-Asia distance by ~8,900 km
  • Panama Canal: 1914, Panama, lock-based; 2016 expansion added New Panamax lanes
  • GERD: Grand Ethiopian Renaissance Dam on Blue Nile; ~5,150 MW; Ethiopia-Egypt-Sudan dispute
  • South China Sea: 2016 Permanent Court of Arbitration ruled against China's nine-dash line
  • India's coal reserves: 5th largest globally (~140.8 billion tonnes)

For Mains:

  • Resource geography answers should follow: where it is → who controls it → why it matters geopolitically → India's strategy
  • For critical minerals: always link to the clean energy transition and electric vehicles — this is the primary demand driver
  • Chinese dominance in rare earths: use as an example of economic coercion (2010, 2023 export restrictions)
  • Water stress: use both international (MENA, GERD) and domestic (NITI Aayog, groundwater) dimensions
  • BRI and resource access: a dimension for both resource security AND India's neighbourhood strategy
  • Chokepoint vulnerability: how a disruption at Hormuz, Malacca, or Bab-el-Mandeb cascades through global supply chains; India's exposure as an import-dependent economy
  • Arctic: melting ice + resources + Northern Sea Route + sovereignty claims — link to India's Arctic Policy 2022
  • Ukraine war → food geopolitics → impact on Global South (GS2 International Relations angle)

Key Data Points:

  • Strait of Hormuz: ~20% of global petroleum liquids (~20 million b/d in 2024)
  • DRC cobalt share: ~70-84% of production
  • Lithium Triangle reserves: ~56% of global known reserves
  • China REE refining: ~91% of global refining
  • India freshwater use: largest groundwater extractor globally
  • GERD capacity: ~5,150 MW — Africa's largest hydroelectric project
  • Arctic: ~30% of world's undiscovered gas; ~13% of undiscovered oil (USGS)
