    • Examples: Iron and Steel

  • Light Industries:

    • Use light materials to produce lighter goods (e.g., Electrical Industries)

Economic Contributions

  • Contribution to industrial production: 14%

  • Employment: 3.5 crore individuals

  • Foreign exchange earnings: Approximately 24.6%

  • Contribution to GDP: 4%

Cotton Textile Industry

  • Historical Practices: Hand spinning and weaving in ancient India; power looms introduced in the 18th century

  • Impact of Colonial Rule: Competition with imported mill-made cloth from England

  • First successful textile mill: Established in Mumbai in 1854

  • Concentration in Maharashtra and Gujarat due to:

    • Availability of raw materials

    • Market access

    • Transport networks and labor supply

    • Favorable climate conditions

  • Place of Exports: Yarn to Japan; Cotton goods to USA, UK, Russia, etc.

  • Current Issues:

    • Poor-quality yarn production

    • Increased global competition

    • Erratic power supply

    • Machinery upgrades needed

    • Low labor output

Jute Industry

  • India: Largest producer of raw jute; 2nd largest exporter of jute goods

  • Major concentration near Kolkata with historical establishment in 1859

  • Factors for Hugli basin location:

    • Proximity to production areas

    • Affordable water transport

    • Complementary transport networks

    • Availability of water and labor

Sugar Industry

  • Global Rank: 2nd in sugar production,

  • Defined by high sucrose content and cooler climates in southern/western regions

  • Current Challenges:

    • Seasonal production nature

    • Old production methods
