Industries
Introduction
An INDUSTRY is an ECONOMIC activity that involves the PROCESSING of RAW MATERIALS into FINISHED goods. Industries are the BACKBONE of any economy — they provide EMPLOYMENT, produce ESSENTIAL goods, and contribute to a COUNTRY'S wealth.
1. Classification of Industries
Industries can be classified in THREE ways:
A. Based on Raw Material
| Type | Description | Example |
|---|---|---|
| AGRO-BASED | Uses AGRICULTURAL raw materials | Cotton textile, sugar, tea, coffee, rubber |
| MINERAL-BASED | Uses MINERAL ores | Iron and steel, aluminium, cement |
| MARINE-BASED | Uses SEA resources | Fish processing, seafood, salt |
| FOREST-BASED | Uses FOREST products | Paper, furniture, bamboo products |
| ANIMAL-BASED | Uses animal products | Leather, wool, dairy |
B. Based on Size
| Type | Description | Example |
|---|---|---|
| LARGE-SCALE | HUGE investment; many workers; advanced technology | Steel plants, automobile factories |
| SMALL-SCALE | Smaller investment; FEWER workers | Pottery, handicrafts, small workshops |
| COTTAGE | VERY small; done in HOMES; family labour | Handloom weaving, basket making |
C. Based on Ownership
| Type | Description | Example |
|---|---|---|
| PUBLIC SECTOR | OWNED and managed by the GOVERNMENT | SAIL (Steel), BHEL |
| PRIVATE SECTOR | OWNED by INDIVIDUALS or companies | TATA, Reliance, Infosys |
| JOINT SECTOR | OWNED by BOTH government and private | Maruti Suzuki (originally) |
| COOPERATIVE | OWNED by a GROUP of producers | AMUL (dairy cooperative) |
2. Factors Affecting Location of Industries
| Factor | Explanation |
|---|---|
| Raw materials | Industries locate NEAR sources of raw materials (especially BULKY ones) |
| Power/Energy | ACCESS to electricity, coal, gas, or oil is ESSENTIAL |
| Labour | AVAILABILITY of skilled and unskilled workers |
| Transport | GOOD road, rail, or port connections for MATERIAL MOVEMENT |
| Market | CLOSE to where products are SOLD reduces transport cost |
| Capital | ACCESS to MONEY for investment |
| Water | MANY industries need LARGE amounts of water |
| Government policies | TAX benefits, subsidies, SEZs attract industries |
| Historical factors | TRADITIONAL skills or EXISTING industrial base |
TENDENCY: Industries TEND to AGGLOMERATE (cluster together) because:
- Sharing of RESOURCES and INFRASTRUCTURE
- Availability of SKILLED labour
- Access to MARKETS and SERVICES
3. Major Industries
A. Iron and Steel Industry
Why Important: Steel is the BACKBONE of modern INDUSTRY — used in construction, automobiles, ships, railways, and machines.
Raw Materials:
- IRON ORE (main raw material)
- COAL (for energy and coke)
- LIMESTONE (as flux — removes impurities)
- MANGANESE (for strength)
Process:
- Iron ore, coke, and limestone are heated in a BLAST FURNACE
- Iron is EXTRACTED → PIG IRON
- Pig iron is FURTHER processed → STEEL in a STEEL FURNACE
- Steel is SHAPED into sheets, rods, beams, etc.
Major Steel Plants in India:
| Plant | Location | State |
|---|---|---|
| TATA STEEL | Jamshedpur | Jharkhand |
| SAIL (Bhilai) | Bhilai | Chhattisgarh |
| SAIL (Rourkela) | Rourkela | Odisha |
| SAIL (Durgapur) | Durgapur | West Bengal |
| SAIL (Bokaro) | Bokaro | Jharkhand |
| VISL | Bhadravati | Karnataka |
| JSW Steel | Vijayanagar | Karnataka |
B. Cotton Textile Industry
Why Important: India is ONE of the LARGEST producers and exporters of cotton textiles.
Raw Material: COTTON (grown in black soil regions of Maharashtra, Gujarat)
Major Centres:
| Centre | State | Reason |
|---|---|---|
| Mumbai | Maharashtra | Port, cotton from Gujarat, skilled labour |
| Ahmedabad | Gujarat | 'MANCHESTER of India'; cotton growing region |
| Coimbatore | Tamil Nadu | Cotton from surrounding areas |
| Kanpur | Uttar Pradesh | Cotton from the plains |
| Ludhiana | Punjab | Woollen and cotton textiles |
C. Sugar Industry
Raw Material: SUGARCANE (tropical crop — needs hot, wet climate)
Important Features:
- SUGARCANE is HEAVY and PERISHABLE — mills must be CLOSE to farms
- India is the SECOND LARGEST producer of sugar in the world
- Major states: Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Bihar
D. Information Technology (IT) Industry
Why Important: India is a GLOBAL leader in IT services.
Major Centres:
| Centre | Known As | Key Companies |
|---|---|---|
| Bengaluru | 'SILICON VALLEY of India' | Infosys, Wipro, TCS |
| Hyderabad | Cyberabad | Microsoft, Google, Amazon offices |
| Pune | Educational hub | TCS, Infosys |
| Chennai | Detroit of India (also IT) | Cognizant, TCS |
| Gurugram/Noida | NCR hub | Many MNC offices |
4. Industrial Regions of India
| Region | States/Districts | Industries |
|---|---|---|
| Mumbai-Pune | Maharashtra | Textiles, IT, automobiles, chemicals |
| Hooghly-Kolkata | West Bengal | Jute, textiles, steel, chemicals |
| Chotanagpur | Jharkhand, West Bengal | Steel, mining, heavy engineering |
| North-West | Gujarat | Textiles, chemicals, petrochemicals |
| Bangalore-Chennai | Karnataka, Tamil Nadu | IT, automobiles, textiles |
| Delhi-Meerut | Uttar Pradesh, Haryana | Light engineering, IT, manufacturing |

Self-Test
-
What are the FOUR types of industry CLASSIFICATION based on raw material? Answer: AGRO-based (cotton, sugar, tea), MINERAL-based (iron and steel, cement), MARINE-based (fish processing), and FOREST-based (paper, furniture).
-
Why is the IRON AND STEEL industry called the 'BACKBONE' of modern industry? Answer: Steel is ESSENTIAL for almost ALL other industries — construction, automobiles, railways, ships, machinery. The economic DEVELOPMENT of a country is often MEASURED by its STEEL production.
-
What FACTORS led to the development of Bengaluru as an IT hub? Answer: Pleasant CLIMATE, presence of EDUCATIONAL institutions (IISc, colleges), GOVERNMENT support, good INFRASTRUCTURE, and the EARLY establishment of PSUs like HAL, BEL, BHEL.
-
Why are SUGAR MILLS located close to sugarcane farms? Answer: Sugarcane is HEAVY and PERISHABLE — it loses SUCROSE (sugar content) quickly after harvesting. It is also EXPENSIVE to transport. Mills must be WITHIN 50 km of the farms.
-
What is the DIFFERENCE between PUBLIC SECTOR and PRIVATE SECTOR industries? Answer: PUBLIC sector is OWNED by the GOVERNMENT (e.g., SAIL, BHEL). PRIVATE sector is OWNED by INDIVIDUALS or companies (e.g., Tata, Reliance). Both are important for the economy.
-
Which city is called the 'MANCHESTER of India'? Why? Answer: AHMEDABAD is called the 'Manchester of India' because of its LARGE cotton textile industry. Manchester (UK) was the centre of the Industrial Revolution's textile industry.
