Class 8 Geography  |Chapter 4 Industries


Introduction 


Industry involves producing goods, extracting minerals, or providing services. Examples include iron and steel production, coal mining, and tourism services.






Classification of industries :


Classification based on raw materials:

  • Agro-based industries: Use plant and animal-based products (e.g., food processing, textile, dairy).

  • Mineral-based industries: Utilize mineral ores as raw materials (e.g., iron and steel industry).

  • Marine-based industries: Rely on sea and ocean products (e.g., seafood processing).

  • Forest-based industries: Utilize forest produce (e.g., pulp and paper, pharmaceuticals).


  • Classification based on size:

    • Small-scale industries: Lesser capital, manual production (e.g., cottage industries, handicrafts).

    • Large-scale industries: High capital, advanced technology (e.g., automobile, heavy machinery).

  • Classification based on ownership:

    • Private sector industries: Owned by individuals or groups.

    • Public sector industries: Owned and operated by the government.

    • Joint sector industries: Owned by both state and individuals or groups.

    • Cooperative sector industries: Owned and operated by producers, workers, or both (e.g., Anand Milk Union Limited, Sudha Dairy).


Industrial System


Industrial System Components:

  • Inputs: Raw materials, labor, land, transport, power, and infrastructure costs.

  • Processes: Various activities transforming raw materials into finished products.

  • Outputs: End products and the associated income.

  • Example: In the textile industry, inputs involve cotton, labor, and production costs. Processes include ginning, spinning, weaving, dyeing, and printing, resulting in the output of a finished shirt.

  • Iron and Steel Industry:

    • Inputs: Iron ore, coal, limestone, labor, capital, site, infrastructure.

    • Processes: Blast furnace smelting, refining.

    • Output: Steel used as raw material in various industries.

  • Steel Applications:

    • Tough, easily shaped, cut, or made into wire.

    • Special alloys for unique properties.

    • Backbone of modern industry, used in transportation, construction, machinery.

  • Historical Evolution:

    • Initially near raw materials and power; later near coal fields and transportation.

    • Post-1950, large areas near seaports due to increased scale and need for imported iron ore.

  • Indian Steel Industry:

    • Development based on raw materials, labor, transport, market.

    • Key centers: Bhilai, Durgapur, Burnpur, Jamshedpur, Rourkela, Bokaro, Bhadravati, Vijay Nagar, Vishakhapatnam, Salem.
