World Resources and their Distribution

World Resources

  • Anything that can be used to satisfy a need is a resource“. A resource is a source or supply from which benefit is produced. Resources are vital to the existence of people.
  • Changing Perspective:
    • Traditional view → resources as given by nature.
    • Modern view → resources are dynamic, socially constructed, and technology-dependent.
  • Geographical Significance: Resource distribution explains spatial inequality, patterns of trade, economic development, and even geopolitical tensions.

Classification of World Resources

  1. On basis of origin – Natural (land, water, minerals, forests) vs. Human (skills, institutions, capital).
  2. On renewability – Renewable (forests, fisheries, solar) vs. Non-renewable (coal, oil, minerals).
  3. On distribution – Ubiquitous (air, sunlight) vs. Localized (oil, uranium, rare earths).

Factors Governing Resource Distribution

  • Geological factors: e.g., mineral belts shaped by tectonics (Canadian Shield, South African plateau).
  • Climatic factors: rainfall determines soil fertility, vegetation, water resources.
  • Historical–technological factors: colonial exploitation shaped global resource geography (oil in Middle East, cotton in India).
  • Economic & political factors: investments, technology, and geopolitics (OPEC, Arctic oil disputes, Rare Earths controlled by China).

Energy Resources and their Distribution

Coal

  • Coal is also the cheapest source of power if used near the coal mines. Since it is bulky, its transportation to far-off places involves high costs. For this reason, the industries which consume a large quantity of coal, are located near coal mines.
  • Coal is the oldest source of commercial energy and was the backbone of the Industrial Revolution. It is still the second largest source of primary energy (26%) and accounts for 36% of global electricity generation (IEA, 2023).
  • Coal is used as a source of power for running machines, trains, ships, etc. Coal is also essential for the manufacture of iron and steel and a variety of chemicals. Coal-tar and chemicals such as ammonia, benzol, etc. are obtained as by-products in the manufacture of iron and steel when coal is burnt to get the coke.
  • The coal deposits although exist in nearly every part of the world, but commercially exploitable coal reserves are found mainly in China, USA, India, Australia, Indonesia, Russia, Canada, South Africa, Columbia, Kazakhstan, and Ukraine.

uranium distribution in world upsc

Thorium

  • Thorium (Th-232) is a radioactive metal, about 3–4 times more abundant than Uranium in the earth’s crust.
  • Unlike Uranium-235, thorium is not fissile but fertile → it absorbs neutrons to form fissile U-233, which can be used in nuclear reactors.
  • Major source: Monazite sands (phosphate mineral) found in coastal regions.
    • Commercially viable deposits of Monazite can be found mainly in the beach sands in the coastal tracts of India, Brazil, Australia, Ceylon, and Malaysia.
  • Estimated world reserves: ~6.5–7 million tonnes (IAEA & OECD/NEA, 2022).
  • India has one of the largest reserves (~25% of global), but globally thorium is underutilized due to technology constraints.
Distribution of Thorium
  • India (≈ 25% of world reserves)
    • India is the largest holder of monazite sand deposits.
    • Major regions:
      • Kerala (Chavara, Quilon, Aluva beaches) – richest deposits.
      • Tamil Nadu (Manavalakurichi, Tuticorin, Kanyakumari).
      • Odisha (Chhatrapur-Gopalpur beach sands).
      • Andhra Pradesh (Bhimunipatnam, Srikakulam).
      • Maharashtra (Ratnagiri coast).
    • Inland deposits: Jharkhand (Singhbhum), Madhya Pradesh.
    • India’s Nuclear Policy – Thorium is central to the 3-stage nuclear programme:
      • Stage I: Pressurised Heavy Water Reactors (PHWRs) using natural uranium.
      • Stage II: Fast Breeder Reactors (FBRs) producing plutonium.
      • Stage III: Thorium-based reactors (Advanced Heavy Water Reactors, AHWRs).
