Secondary Activities

Secondary Activities: • Secondary activities involve the processing of raw materials (from primary activities) into finished or semi-finished goods — i.e., manufacturing and processing. • They add value to natural materials — turning iron ore into steel, cotton into cloth, wheat into flour. • Secondary activities are the basis of industrial development. Types of Manufacturing Industries: 1. By Scale: (a) Cottage Industries (Household Industries): • Small-scale production in homes using family labour and simple tools. • Products: Handicrafts, pottery, weaving, wood carving. • Examples: Handloom weaving in India, carpet making in Afghanistan, batik in Indonesia. • Characteristics: Labour-intensive, low capital, traditional skills, local materials. (b) Small-Scale Industries: • Larger than cottage industries but smaller than large-scale — workshops, small factories. • Use some machinery and hired labour. • Important for employment in developing countries. (c) Large-Scale Industries: • Modern factories using advanced machinery, large capital, and hundreds or thousands of workers. • Examples: Steel plants, automobile factories, petrochemical complexes. 2. By Function: (a) Heavy Industries: Process heavy raw materials — steel, aluminium, cement, chemicals. Need large inputs of energy and materials. (b) Light Industries: Process lighter raw materials or components — electronics, textiles, food processing. (c) Basic Industries: Produce capital goods (machinery, steel) used by other industries. (d) Consumer Industries: Produce goods for direct consumption (food, clothing, electronics). 3. By Ownership: (a) Public sector: Government-owned (SAIL, BHEL in India). (b) Private sector: Privately owned (Tata Steel, Reliance). (c) Joint sector / Mixed.

Factors Affecting Industrial Location: • Industries are located where they can minimise costs and maximise profits — the location is the result of a combination of physical, economic, social, and political factors. Alfred Weber's Least Cost Theory: • Alfred Weber (1909) argued that industries locate where transport costs + labour costs are minimised. • Two pull factors: Raw material sources and markets; two weight-losing factors determine transport. • Agglomeration economies: Industries cluster together to share infrastructure and services. Physical Factors: 1. Raw Materials: Industries that use heavy, bulky, or weight-losing raw materials locate near the source. • Steel plants near iron ore and coal deposits (Jamshedpur near Jharkhand/Odisha iron ore; Rourkela, Bhilai). • Sugar mills in UP and Maharashtra near sugarcane fields. 2. Power: Energy-intensive industries locate near power sources. • Aluminium smelting near hydroelectric power (Norway, Pacific Northwest USA). • Thermal power plants near coalfields. 3. Water: Many industries need large water supplies — chemical plants, paper mills, textile mills near rivers. 4. Climate: Some industries require specific climatic conditions — cotton textiles flourish in humid climates (Mumbai). Economic Factors: 5. Labour: Labour-intensive industries locate where skilled or cheap labour is available. • IT industry in Bangalore (skilled software engineers); garment industry in Bangladesh (cheap labour). 6. Capital: Industries need capital — financial centres attract diverse industries. 7. Transport: Good roads, railways, ports — reduce costs of moving raw materials and finished goods. • Port cities became industrial centres: Mumbai, Kolkata, Shanghai, Rotterdam. 8. Market: Consumer goods industries locate near large population centres. • Bakeries, breweries, soft drink factories near cities. 9. Agglomeration economies: Industries cluster together — shared infrastructure, supplier networks, skilled labour pools. • Silicon Valley (IT), Detroit (automobiles historically), Sheffield (steel historically). Social and Political Factors: 10. Government policy: Tax concessions, subsidies, special economic zones attract investment. 11. Historical factors: Industries established in a location attract more industries. 12. Infrastructure: Reliable electricity, water supply, internet connectivity.

Industrial Regions: • Industrial regions are areas where manufacturing industries are highly concentrated — due to favourable combinations of raw materials, labour, capital, transport, and market. • Major industrial regions developed during the Industrial Revolution (18th–19th century) in Europe and North America. 1. Eastern North America (Manufacturing Belt): • The traditional industrial heartland of the USA and Canada — from the Great Lakes to the Atlantic coast. • States: Ohio, Michigan, Indiana, Pennsylvania, New York, Illinois. • Key industries: Steel (Pittsburgh), automobiles (Detroit), chemicals, machinery. • Resources: Great Lakes iron ore (Minnesota, Michigan), Appalachian coal (Pennsylvania, West Virginia), water transport (Great Lakes, Mississippi). • Markets: Largest consumer market in the world. • Challenges: Deindustrialisation from the 1970s — factories closed as manufacturing moved to lower-wage regions (Sun Belt, Asia). The 'Rust Belt' is the legacy. 2. Western Europe (Rhine-Ruhr Industrial Region): • The Rhine-Ruhr valley in Germany — one of the world's densest industrial concentrations. • Key industries: Steel, chemicals, engineering, automotive (Volkswagen, Mercedes, BMW). • Resources: Ruhr coalfield (once Europe's largest), Rhine River for transport. • Cities: Essen, Dortmund, Düsseldorf, Cologne. • Also includes: Belgium's Sambre-Meuse valley, France's Lorraine (iron ore), UK's Midlands (birthplace of Industrial Revolution — Birmingham, Sheffield, Manchester, Leeds). 3. Eastern China (Yangtze River Delta / Pearl River Delta): • Since the 1980s, China has become the world's manufacturing centre. • Yangtze Delta (Shanghai, Suzhou, Hangzhou): High-tech manufacturing, automobiles, electronics. • Pearl River Delta (Guangzhou, Shenzhen): Consumer electronics, textiles, toys — 'the world's factory floor.' • Resources: Cheap labour (historically), vast domestic market, government investment in infrastructure. 4. India's Industrial Regions: • Mumbai-Pune: Cotton textiles, chemicals, petrochemicals, IT. • Bengaluru-Chennai corridor: IT, aerospace, automobiles. • Damodar Valley: Steel, heavy engineering (Jamshedpur — Tata Steel, India's first integrated steel plant).
