Water scarcity risks production, but solar power adoption reduces emissions (15% decline since 2020).

Agro-based industries use agricultural raw materials (e.g., cotton, sugarcane), while mineral-based industries rely on minerals (e.g., iron, bauxite). Our textbook shows these are classified under secondary activities.

• Agro-based: Boosts rural economy (e.g., Maharashtra’s cotton industry).
• Mineral-based: Causes land degradation (e.g., Odisha’s mining).

Footloose industries are not tied to raw material sources (e.g., electronics, pharmaceuticals). We studied their flexibility in location choice.

• Promotes urban growth (e.g., Hyderabad’s HITEC City).
• GIS helps optimize infrastructure (e.g., Mumbai’s metro routes).

The cotton textile industry processes raw cotton into fabrics. Mumbai, once a hub, faces decline due to multiple factors.

• Erratic monsoons (Köppen: Am) reduce cotton yield.
• Rising temperatures (Aw) increase production costs.

Public sector industries are government-owned (e.g., SAIL), while private ones are corporate-run (e.g., Tata Steel). Our textbook highlights their operational differences.

• Public sector: Balances regional disparities (e.g., NTPC in Bihar).
• Private sector: Drives innovation (e.g., Pune’s auto cluster).

The automobile industry manufactures vehicles and components. Tamil Nadu (e.g., Chennai) is a major hub due to favorable conditions.

• Aw climate ensures year-round production (no extreme winters).
• Coastal location (Chennai) mitigates heat island effect.
