Distribution of Key Natural Resources across the World

• A natural resource is anything obtained from the environment to satisfy human needs and wants: sunlight, water, air, soil, minerals, plants and animals.
• Natural resources are unevenly endowed across the Earth. Some regions are rich in one resource and poor in another, and few countries are self-sufficient in all.
• The geography of endowment (who has what), the geography of extraction (how and where it is mined) and the geography of consumption (who uses it) rarely coincide. The gaps between them drive trade, investment, development and geopolitics.

Resource Endowment and Its Uneven Geography

The Basis of Resource Endowment

• Every resource has utility (usability) and value (worth). A beautiful landscape or fresh air has value even without a market price.
  • Utility depends on time and technology. In Zimmermann’s functional view of world resources, “resources are not, they become“.
• Endowment does not equal development. Japan, South Korea and Singapore grew rich with few natural resources. Resource-rich states such as the DRC, Nigeria and Venezuela remain poor, a pattern called the resource curse.
• Who extracts and who consumes: developing countries often hold resources but lack the capital or technology to work them.
  • Transnational corporations (TNCs) pay royalties for extraction rights and export the output to industrial countries.
  • High-income countries use about six times more materials per person than low-income countries. They can afford to import what they lack.
• The Strategic Ellipse: about seven-tenths of the world’s conventional oil and gas reserves lie in a belt from the Persian Gulf through the Caspian to West Siberia. This concentration makes the region the hinge of energy geopolitics.

• Renewable resources are replenished by nature in a short time, but at different rates.
• Non-renewable resources form over very long geological periods. After the Industrial Revolution and the population explosion, their demand rose exponentially. This caused rapid depletion, habitat destruction and pollution, and led to the idea of sustainable development.

Minerals: Nature, Types and Extraction

What Is a Mineral

• A mineral is a naturally occurring, inorganic solid with a definite chemical composition and an ordered atomic arrangement.
  • It is natural, not made by humans, and inorganic, never alive.
  • It is a solid, not a liquid or gas, with a fixed mix of elements.
  • Its atoms are arranged in a regular pattern, which is why minerals grow as crystals.
• Minerals are finite and non-renewable. They are the raw material of basic industries, so their management must be tied to long-term national development goals.

Types of Minerals

Modes of Occurrence

• Veins and lodes: metals such as tin, copper, zinc, lead and gold fill cracks and joints in igneous and metamorphic rocks.
• Beds and layers: coal, gypsum, potash and some iron ore lie in sedimentary strata.
• Residual deposits: bauxite and lateritic nickel form when weathering removes soluble rock and leaves the ore behind.
• Placer (alluvial) deposits: gold, tin, diamonds, platinum and monazite collect in river and beach sands.
• Ocean waters and seabed: salt, magnesium and bromine from seawater, and polymetallic nodules on the deep-ocean floor. These belong to marine resources.

Methods of Extraction

• Open-pit mining is cheaper and safer for workers, but it scars large areas, produces huge waste dumps and lowers groundwater.
• Underground mining disturbs less surface, but it is costlier and riskier: roof falls, gas explosions and flooding.

Uses of Minerals

• Construction: granite (quartz, feldspar and mica) is a hard building stone. Limestone is the base of cement, and gypsum is used in plaster casts and cement.
• Industry and daily life:
  • Graphite makes pencil leads and battery anodes, and talc goes into crayons and paints.
  • Sulphur goes into matches, explosives, sulphuric acid, fertilisers and dyes.
• Metals:
  • Iron from haematite, magnetite and limonite makes steel for ships, vehicles, machines and buildings, and manganese is essential for steel-making.
  • Copper, from chalcopyrite, is a fine conductor used in wires, cables and electronics, and in plumbing, roofing and coins.
  • Aluminium from bauxite is light and strong. It is used in aircraft, vehicles, cans, foil and power lines.
• Precious metals and gems: gold, silver and platinum go into jewellery, coins, electronics, dentistry and medicine.
  • Precious stones (diamond, ruby, sapphire, emerald) and semi-precious stones (garnet, topaz, amethyst, opal) are cut, polished and set in metal.
  • Diamond, the hardest mineral, is used in cutting tools.
• Living things: iron is needed for haemoglobin, and zinc, copper, manganese and fluoride are needed in small amounts in the diet.

Conservation of Minerals

• Minerals cannot be replenished, and they belong to present and future generations alike.
• Reduce, reuse, recycle: recycling scrap steel, aluminium and copper cuts both mining and energy use.
• Substitution and research: develop replacement minerals, avoid waste in mining and processing, and use by-products fully.
• Better mining: curb wasteful methods, train miners in modern techniques and limit environmental damage.
• Location and value addition: locate processing plants near mines to cut transport costs. Convert bulky coal into power at pithead plants.
• Exploration: use modern geophysical methods on land and in the Exclusive Economic Zone (EEZ) to find new reserves.

Fossil Fuels: Types and Grades

• Energy for heat and electricity comes from conventional and non-conventional sources.

• Firewood is still the main cooking fuel for many rural households. It is inconvenient and time-consuming to collect, releases smoke and carbon monoxide that harm health, and contributes to deforestation.
• Fossil fuels (coal, petroleum and natural gas) are the remains of plants and animals buried for millions of years.

Coal and Its Ranks

• Coal is a combustible sedimentary rock. It formed from swamp-forest plants buried for millions of years and turned by heat and pressure into ever denser, drier and more carbon-rich material, a process called coalification.
• The rank of coal depends on how much heat and pressure acted on it.

• Indian coal belongs to two ages.
  • Gondwana coal (Permian–Triassic) gives about 98% of reserves. It lies in the Damodar, Mahanadi, Son, Godavari and Wardha valleys and is mostly bituminous to sub-bituminous, with high ash.
  • Tertiary coal is found in Assam, Meghalaya, Nagaland and Arunachal Pradesh. It is young and high in sulphur. Lignite occurs in Tamil Nadu, Gujarat and Rajasthan.

Crude Oil and Natural Gas

• Formation: algae, plankton and plants of ancient shallow seas sank, mixed with sediment and were buried. Over millions of years, heat and pressure turned them into hydrocarbons that collected in porous reservoir rocks under impermeable cap rocks.
• Composition: crude oil is about 85% carbon and 13% hydrogen by weight, with small amounts of sulphur, nitrogen, oxygen and metals. Its colour ranges from black and brown to greenish and nearly clear.
• Advantages: oil is a compact liquid fuel that leaves no ash and moves cheaply by tanker and pipeline. It powers transport and feeds thousands of petrochemical products, from tyres to medicines.
• Disadvantage: burning oil and gas releases CO₂ and other pollutants, so they are major drivers of climate change.
• Natural gas often occurs with oil (associated gas) and is released when crude is brought up. It is also found alone in non-associated reservoirs.

Grades and Benchmarks of Crude Oil

• WTI and Brent are both light and sweet. Dubai–Oman crude is medium and sour.
• Venezuela’s Orinoco crude and Canada’s oil-sands bitumen are extra-heavy and need special upgrading.

Regional Resource Profiles of the World

• Read region by region, the world resource map shows a few resource giants with diverse endowments (Russia, the USA, Canada, Australia, China, Brazil). Many smaller economies depend on one or two commodities.

North America

• USA: the largest producer of both oil (about 21 million barrels per day, from the shale of the Permian basin and the Bakken) and natural gas. It holds the world’s largest coal reserves.
  • It also mines copper (Arizona, Utah), gold (Nevada), molybdenum and rare earths (Mountain Pass, the largest producer outside China).
  • Iron ore comes from the Mesabi Range of Minnesota. The old Birmingham (Alabama) iron district is long worked out.
• Canada: about 170 billion barrels of oil reserves, mostly the Athabasca oil sands of Alberta.
  • It is the largest producer of potash (Saskatchewan, about three-tenths of world output) and the second-largest miner of uranium (Athabasca basin).
  • It mines iron ore in the Labrador Trough (Quebec–Labrador) and nickel–copper at Sudbury (Ontario).
  • It also produces gold, diamonds (Northwest Territories), aluminium (on cheap hydropower), timber and fresh water.

Latin America

• Chile: the world’s largest copper miner (Atacama). It holds the largest lithium reserves in the brines of the Salar de Atacama.
• Peru: copper, silver, zinc and gold from the Andes.
• Brazil: iron ore (Carajás, Minas Gerais), bauxite, and nearly all the world’s niobium (about 93%, from Araxá).
  • Brazil also has pre-salt offshore oil, hydropower and the Amazon’s biotic wealth.
• The Lithium Triangle of Argentina, Bolivia and Chile holds over two-fifths of the world’s identified lithium resources.
• Mexico is the largest silver producer. Guyana became an oil exporter in 2019 from the Stabroek block.
• Venezuela:
  • It holds the world’s largest proven oil reserves (about 304 billion barrels), mostly the extra-heavy crude of the Orinoco Belt, plus older fields around Lake Maracaibo.
  • It was a founder member of OPEC (1960) and a leading exporter for most of the 20th century.
  • Output fell from over 3 million barrels per day in the late 1990s to below 1 million barrels per day in the mid-2020s.
  • The decline came from under-investment, mismanagement of the state firm PDVSA, the cost of upgrading heavy crude, and US sanctions from 2017–19.
  • Its exports shifted from the USA to China and India. Its huge reserves remain largely potential rather than actual production.

Europe

• Europe is resource-poor relative to its consumption and is a large importer of energy and metals.
• North Sea: oil and gas of Norway (Johan Sverdrup, Troll) and the UK. Norway is now Europe’s largest gas supplier after Russian pipeline gas was cut back from 2022.
• Sweden: high-grade iron ore at Kiruna, where Europe’s largest known rare-earth deposit was announced in 2023.
• Ukraine: high-grade iron ore at Kryvyi Rih, manganese at Nikopol, coal of the Donbas, and lithium and titanium prospects. Many of these sites have been disrupted by the war.
• Others: potash in Germany, Belarus and Spain; copper in Poland (Lubin); historic coal of the Ruhr, Silesia and Wales; and the Lorraine iron ore (minette) that once fed French and German steel.

Russia and Central Asia

• Russia is self-sufficient in almost every industrial raw material.
  • It has the largest natural gas reserves (West Siberia, Yamal) and large oil reserves. It is a leading producer of nickel and palladium (Norilsk), diamonds (Yakutia), gold, aluminium, potash and coal (Kuzbass).
  • Siberian inaccessibility long delayed the development of these resources.
• Central Asia:
  • Kazakhstan is the largest uranium producer, with oil at Tengiz and Kashagan and coal at Karaganda–Ekibastuz.
  • Turkmenistan holds huge gas reserves (Galkynysh).
  • Uzbekistan mines gold (Muruntau) and uranium.

Middle East and North Africa

• The Persian Gulf holds close to half of the world’s proven oil reserves and about two-fifths of its gas.
  • Saudi Arabia (Ghawar), Iran, Iraq, Kuwait and the UAE dominate oil reserves.
  • Qatar and Iran share the giant South Pars–North Dome gas field.
• Phosphate: Morocco (with Western Sahara) holds about seven-tenths of the world’s phosphate rock reserves, the basis of fertilisers. Saudi Arabia and Jordan also mine phosphate.
• North Africa: oil and gas of Algeria (Hassi Messaoud, Hassi R’Mel), Libya (Sirte basin) and Egypt (Zohr gas field).

Sub-Saharan Africa

• Africa holds a large share of the world’s mineral reserves, but most are exported raw.
• Democratic Republic of the Congo (DRC): about three-quarters of the world’s mined cobalt and the second-largest copper output, from the Katanga Copperbelt.
• Zambia: copper of the Copperbelt.
• Guinea: the largest bauxite producer and reserve holder (Boké). The Simandou iron-ore project began exporting in 2025.
• South Africa:
  • It mines most of the world’s platinum (Bushveld complex) and the largest share of manganese (Kalahari). It is also a major producer of chromite.
  • Witwatersrand gold made it the leading gold producer for most of the 20th century.
• Gabon and Ghana mine manganese, and Ghana also mines gold.
• Botswana produces diamonds of the highest value (Jwaneng, Orapa). Namibia mines uranium and has marine diamonds.
• Oil and gas: Nigeria (Niger delta) and Angola produce oil. Mozambique (Rovuma basin) and Tanzania have gas.
• Agricultural and biotic resources: cocoa (Côte d’Ivoire, Ghana), timber of the Congo basin, and tropical fruits.

China

• China is the world’s largest producer of coal (about half of world output), rare earths, graphite, tungsten, antimony and gold. It is also a major producer of molybdenum, vanadium, zinc, lead and tin.
• China’s real strength is processing: it is the leading refiner for 19 of 20 energy-related strategic minerals, with an average share of about 70%.
• China is also the largest importer of iron ore, copper concentrate, oil and soybeans, because its demand far exceeds its domestic supply.

South and Southeast Asia

• Indonesia: about two-thirds of the world’s nickel, the second-largest output of tin (Bangka–Belitung), the largest coal exports, and palm oil.
• Malaysia: tin (historically the Kinta Valley), palm oil, rubber, and natural gas (Sarawak).
• Myanmar: tin and rare earths (Kachin and Shan States), jade, rubies and gas.
• Vietnam: large reserves of rare earths and bauxite.
• India: coal, iron ore, bauxite, chromite and thorium-bearing monazite, set out in detail at the end.

Australia and Oceania

• Australia is a mining superpower with a resource-dependent economy.
  • It is the largest producer of iron ore (Pilbara) and lithium (spodumene from Western Australia), and the second-largest producer of bauxite.
  • It is a major producer of gold, zinc, lead, rare earths and mineral sands.
  • It holds the largest share of recoverable uranium (Olympic Dam).
  • It is a leading exporter of coal (Bowen basin, Hunter Valley) and LNG (North West Shelf). Japan, China, South Korea and India are its chief buyers.
• Most of Australia’s mining lies in Western Australia and Queensland. Its gas fields are far from the eastern cities, so long pipelines and export LNG plants link them to markets.
• New Caledonia (nickel) and Papua New Guinea (gold, copper, LNG) are the main mineral economies of the wider Pacific.

Critical Minerals: The New Resource Geography

• Critical minerals are minerals that are essential to the economy and security and whose supply is at risk. They are the lithium, cobalt, nickel, graphite, rare earths and copper behind batteries, electric vehicles, wind turbines, solar panels, electronics and defence.
• Two layers of concentration:
  • Mining is concentrated in a few countries: the DRC for cobalt, Indonesia for nickel, Australia and Chile for lithium, and China for rare earths and graphite.
  • Refining is even more concentrated, mostly in China.
  • The top three producers of key energy minerals supplied about 86% of output in 2024, up from about 82% in 2020.

• Resource nationalism and export controls: about 55% of energy-related strategic minerals face some export restriction.
  • Indonesia banned nickel-ore exports in 2020, and the DRC halted cobalt exports in February 2025 before moving to quotas.
  • China restricted antimony (2024) and rare earths (April and October 2025, with the October measures suspended for a year in November).
• Challenges of extracting and processing critical minerals:
  • Environmental:
    • Lithium brine extraction uses scarce water in the arid Atacama.
    • Nickel smelting and mining have cleared forests and polluted coasts in Sulawesi.
    • Rare-earth processing leaves radioactive and toxic tailings.
    • Mining in general causes acid mine drainage and heavy carbon emissions.
  • Social: artisanal cobalt mining in the DRC has involved child labour and unsafe conditions, and mines often displace indigenous and local communities.
  • Economic: prices swing sharply (lithium prices crashed in 2023–24 after a boom). New mines take 10–15 years to develop, and producers capture little value when ores are exported raw.
  • Geopolitical: dependence on one refining country creates supply-chain risk. This is why the USA, the EU, Japan and India are building alliances such as the Minerals Security Partnership and stockpiles.

India’s Place in the World Resource Map

Mineral Belts of India

• India’s mineral wealth reflects its geology. Most metallic minerals lie in the ancient Precambrian rocks of the Peninsula (Dharwar and Cuddapah systems), coal lies in Gondwana basins, and oil and gas lie in Tertiary sedimentary basins on the margins.

India’s Key Minerals

• India is the world’s largest producer of sponge iron (direct reduced iron), mostly from coal-based plants in mineral-rich states. It is the second-largest crude steel producer.

Energy Resources of India

• Coal:
  • India is the second-largest producer and crossed 1 billion tonnes in 2024–25.
  • Jharkhand, Odisha and Chhattisgarh hold most reserves. Raniganj (West Bengal) saw India’s first coal mine in 1774, and Jharia, Bokaro, Talcher, Korba and Singrauli are the main fields today.
  • Indian coal is mostly high-ash, so coking coal is imported.
• Oil and gas:
  • India is the third-largest oil consumer and imports about 86% of its oil and about half of its gas. It is a leading LNG importer (Dahej, Hazira, Kochi terminals).
  • Its refining capacity of over 250 million tonnes a year makes it a net exporter of petroleum products. Jamnagar is the world’s largest refining complex.
  • Producing areas: Mumbai High, Assam (Digboi, Naharkatia), Gujarat (Ankleshwar, Cambay), Rajasthan (Barmer) and the Krishna–Godavari basin.
• Strategic Petroleum Reserve (SPR): underground rock caverns at Visakhapatnam (1.33 million tonnes), Mangaluru (1.5) and Padur (2.5), together 5.33 million tonnes, enough for roughly nine to ten days of demand.
  • Phase II adds Chandikhol (Odisha) and a second cavern at Padur, about 6.5 million tonnes more.
• Gas hydrates: crystalline methane–water compounds in shallow sediments of the continental margins.
  • India’s national programme found rich sand-hosted hydrates in the Krishna–Godavari basin in 2015. The Mahanadi, Kerala–Konkan and Andaman offshore areas are other prospects.
• Thorium: India’s monazite beach sands contain about 1.07 million tonnes of thorium oxide. Thorium is central to the third stage of the three-stage nuclear programme.
  • Thorium cannot fuel a reactor alone. It must first be converted to fissile U-233 with the help of fast breeder reactors.

• Renewable resources: India had about 299 GW of renewable capacity (including large hydro) by September 2026, with solar about 171 GW and wind about 59 GW. Its total non-fossil capacity crossed 300 GW in 2026, on the way to the 500 GW target for 2030.

Pipelines: Moving Oil and Gas

• Pipelines are the most economical way to move oil, gas, water and even slurries over long distances.
  • Advantages: they cross difficult terrain and the sea floor, use little energy, need little maintenance and are relatively safe.
  • Limitations: they serve only fixed points, their capacity cannot be raised once they are laid, and leaks are hard to detect and guard.

• India’s gas-pipeline network is about 25,000 km long and growing towards a National Gas Grid. The Kandla–Gorakhpur LPG pipeline (about 2,800 km) is under construction.

Critical Minerals and India

• India notified 30 critical minerals in 2023, and in January 2025 it launched the National Critical Mineral Mission to explore at home, acquire mines abroad and build recycling.
• Steps taken:
  • Auctions of critical-mineral and offshore mineral blocks (from 2024).
  • KABIL, a joint venture of three state miners, signed for lithium blocks in Argentina’s Catamarca province in 2024.
  • A seabed contract with the International Seabed Authority for polymetallic nodules in the Central Indian Ocean Basin.
  • Partnerships such as the Minerals Security Partnership.
• Why they matter: India’s goals of 500 GW of non-fossil power, electric mobility, electronics manufacturing and defence production all depend on minerals it largely imports. Securing them is a matter of both economic development and national security.
