Minerals, Energy Resources and Industries of the World Notes

Economic geography studies how people use the Earth's resources to produce, trade and consume goods. It is a favourite area of the UPSC, because the questions ask where a mineral or a crop is found, why an industry developed in a particular region, and how resources shape the politics of countries. This note covers the world's major minerals, energy resources, agriculture and industrial regions, with simple tables and reasons. Learn the locations on a map, because most of the Prelims questions are of the "match the following" or "which country" type. The data on production ranks change from year to year, so treat the lists below as the general leaders and update them from a current source before the exam.

Classification of Resources

Resources are of two broad types. Renewable resources, such as solar energy, wind, water and forests, can be replaced in a short time. Non-renewable resources, such as coal, petroleum, natural gas and minerals, take millions of years to form and can be exhausted. Another way of classification is by ownership (individual, community, national and international) and by development (potential, developed, stock and reserve). Sustainable development means using resources in a way that the needs of the present are met without harming the future generations.

Energy Resources of the World

Petroleum is the "black gold" of the modern economy, and its location decides much of world politics. The Strait of Hormuz, the Suez Canal and the Strait of Malacca are important oil trade routes. Coal fields are close to the industrial regions, such as the Appalachian region in the USA, the Ruhr in Germany and Jharia in India.

Important Minerals and Where They Are Found

The minerals like lithium, cobalt and rare earths are now called "critical minerals", because they are needed for batteries, electric vehicles, solar panels and electronics. Countries are trying to secure their supply chains, and India has launched a National Critical Mineral Mission. This is a good current-affairs link for a Mains answer.

Agriculture: Types and Leading Producers

• Subsistence farming: The farmer grows food mainly for the family; common in monsoon Asia (intensive rice farming).
• Plantation farming: Large estates growing one cash crop like tea, coffee, rubber or palm oil in tropical areas.
• Commercial grain farming: Large, mechanised farms of wheat and maize in the Prairies, the Pampas, the Steppes and the Murray-Darling basin.
• Mediterranean agriculture: Citrus fruits, grapes (viticulture) and olives in lands with warm dry summers and mild wet winters.
• Dairy farming and market gardening: Near cities and in cool areas such as Denmark, the Netherlands and New Zealand.

Industries and Factors of Location

An industry grows at a place where the cost of production is lowest. The main factors are the nearness of raw material, power, labour, market, transport and capital, along with government policy. Weight-losing industries, such as iron and steel and sugar, are located near the raw materials. Footloose industries, like electronics and software, are not tied to a raw material and can be located anywhere with good infrastructure and skilled people. Industries are also classified as primary (extraction), secondary (manufacturing), tertiary (services), quaternary (knowledge and research) and quinary (top decision-making).

Major Industrial Regions

Fishing Grounds

The best fishing grounds of the world are where warm and cold currents meet, because plankton grows there in abundance. The important ones are the Grand Banks near Newfoundland in the North Atlantic, the North Sea, the north-west Pacific near Japan, and the Peruvian coast, where the cold Humboldt Current brings nutrients. The overfishing of such areas is now a serious problem.

Why Resources Matter for Politics

Resource-rich regions often become areas of conflict and cooperation. Oil has shaped the politics of West Asia; the control of sea lanes shapes the strategy in the Indian Ocean and the South China Sea; and the monopoly on rare earths has made countries rethink their supply chains. At the same time, many resource-rich countries suffer from the "resource curse", where dependence on one commodity leads to weak institutions and unstable growth. Read our notes on Indian minerals and industries and the world geography section to link the global picture with India.

Transport, Trade and Global Supply Chains

Resources are useful only when they can be moved to the place of use. Sea transport carries the largest share of world trade because it is cheap for bulk goods like oil, coal and iron ore. Major trade routes pass through the Suez Canal, the Panama Canal, the Strait of Malacca and the Cape of Good Hope. Railways carry heavy goods over land, and the Trans-Siberian Railway links Moscow with the Pacific port of Vladivostok. Pipelines carry oil and gas across countries, and air transport carries high-value and perishable goods. Modern industries depend on global supply chains, where parts are made in many countries and assembled in one. When a canal or strait is blocked, or when a war breaks out, the supply chain is disturbed and prices rise all over the world, as seen in recent years. This is why the safety of sea lanes and the diversification of suppliers have become strategic goals for every country.

Mains Angle: Resource Distribution and Development

A typical Mains question asks why the world's industrial regions are located at a few places, or how the uneven distribution of resources affects countries. A good answer can use three points. First, the natural advantage: coal and iron ore in the same area produced the Ruhr and the Chota Nagpur industrial belts. Second, the role of policy, technology and capital: Japan became an industrial power with few natural resources, by importing raw materials and developing high technology. Third, the effect of globalisation: manufacturing has moved to Asia because of low costs and large markets, while services and research remain strong in the West. Conclude that resources alone do not guarantee development; institutions, skills and trade policy are equally important.

Practice Questions

• Q1. Which country is the largest producer of copper? Answer: Chile.
• Q2. Which mineral is mostly found in the Witwatersrand? Answer: Gold.
• Q3. Where is the Ruhr industrial region? Answer: Germany.

Memory Tips

• Link a mineral with a place by a story: "Copper in Chile, cobalt in the Congo, platinum in South Africa".
• Learn industrial regions as pairs: Ruhr-steel, Detroit-cars, Silicon Valley-chips, Osaka-ships.
• For crops, remember that China and India lead in rice, wheat, tea and cotton, while Brazil leads in sugarcane and coffee.
• Use a blank map to mark resources, and revise it every week.

Quick Revision

• Coal leaders: China, India, USA; oil leaders: USA, Saudi Arabia, Russia.
• Copper: Chile; diamonds: Russia and Botswana; cobalt: DR Congo; rare earths: China.
