Chapter 5: Secondary Activities

Introduction

Secondary activities add value to natural resources by turning raw materials into valuable products. Cotton in the boll has limited use, but as yarn it can make clothes. Iron ore cannot be used straight from the mine, but as steel it makes machines and tools. So secondary activities cover manufacturing, processing and construction (infrastructure) industries.

Key Concepts

1. Manufacturing

Manufacturing ranges from handicrafts and moulding iron and steel to stamping out plastic toys and assembling computer parts or space vehicles. The common features are:

  • the application of power;
  • mass production of identical products;
  • specialised labour in factory settings producing standardised commodities.

    • Manufacturing literally means "to make by hand", but it now includes goods "made by machines". An industry is a geographically located manufacturing unit that keeps books of accounts under a management system. Because "industry" is also used for entertainment and tourism, the longer phrase "manufacturing industry" is used for clarity.

    2. Characteristics of Modern Large-Scale Manufacturing

  • Specialisation of skills and methods. The craft method makes a few pieces to order at high cost. Mass production makes standardised parts, with each worker doing one task repeatedly.
  • Mechanisation. Automation, which works without the aid of human thinking, is its advanced stage. Automatic factories use feedback and closed-loop computer control.
  • Technological innovation. Research and development improve quality control, eliminate waste and combat pollution.
  • Organisational structure and stratification. Complex technology and division of labour need vast capital, large organisations and an executive bureaucracy.
  • Uneven geographic distribution. Major concentrations cover less than 10 per cent of the world's land area. The book's comparison: 2.5 sq km of the American corn belt has about four farms with 10–20 workers supporting 50–100 persons, while the same area could hold factories employing thousands.

    • 3. Location Factors

    Industries locate where production costs are minimum.

  • Access to market is the most important factor. A market means people with demand and purchasing power. Europe, North America, Japan and Australia offer large global markets. Aircraft and arms industries have global markets.
  • Access to raw material. Cheap, bulky, weight-losing materials (ores) keep steel, sugar and cement near their sources. Perishability keeps agro-processing and dairy near farms.
  • Access to labour supply. Mechanisation and automation have reduced dependence on labour.
  • Access to sources of energy. Power-hungry industries such as aluminium locate near energy. Coal was once the main source; hydroelectricity and petroleum now matter too.
  • Access to transportation and communication. Western Europe and eastern North America have industrial concentrations because of their transport systems.
  • Government policy. "Regional policies" promote balanced development.
  • Agglomeration economies. These are the benefits of nearness to a leader-industry and to linked industries.

    • Footloose industries can be located in a wide variety of places.

  • They depend on component parts obtainable anywhere, not on a specific raw material.
  • They produce small quantities with a small labour force.
  • They are generally non-polluting.
  • The key factor in their location is accessibility by road network.

    • 4. Classification of Industries (Fig. 5.1)

    By size, which depends on capital, workers and volume of production:

  • Household or cottage industry. The smallest unit. Artisans use local raw material and simple tools at home with family or part-time labour. Examples are pottery, mats and leather goods. Capital and transport have little influence.
  • Small-scale industry. It uses a workshop outside the home, simple power-driven machines and semi-skilled labour. India, China, Indonesia and Brazil develop it to provide employment.
  • Large-scale industry. It needs a large market, varied raw materials, enormous energy, specialised workers, advanced technology, assembly-line production and large capital. It developed over the last 200 years in the UK, north-eastern USA and Europe. There are two types of region: traditional large-scale regions clustered in a few developed countries, and high-technology regions diffused to less developed countries.

    • By inputs:

  • Agro-based: food processing, sugar, pickles, juices, beverages, spices, oils, textiles and rubber.
  • Mineral-based: ferrous (iron and steel), non-ferrous (aluminium, copper, jewellery) and non-metallic (cement, pottery).
  • Chemical-based: petrochemicals, salts, sulphur, potash, synthetic fibre and plastic.
  • Forest-based: timber for furniture; wood, bamboo and grass for paper; lac.
  • Animal-based: leather, wool and ivory.

    • Agri-business is commercial farming on an industrial scale, financed by business interests outside agriculture. Such farms are described as "agro-factories".

    By output:

  • Basic industries make goods that are used to make other goods. The chain runs iron and steel → machines → textile industry → clothes.
  • Consumer goods (non-basic) industries make goods used directly, such as bread, tea, soap and televisions.

    • By ownership:

  • Public sector: owned by government, such as India's PSUs.
  • Private sector: owned by individuals. This is typical of capitalist countries.
  • Joint sector: run by joint stock companies, or by the private and public sectors together.

    • 5. High-Technology Industry

    High-tech industry applies intensive R and D to products of an advanced scientific character.

  • White-collar professionals outnumber blue-collar production workers.
  • Examples are robotics, CAD, electronic controls of smelting, and new pharmaceuticals.
  • The landscape is low, dispersed, modern office-plant-lab buildings in planned business parks.
  • Regionally concentrated, self-sustained, highly specialised clusters are called technopolies. Examples are Silicon Valley near San Francisco and Silicon Forest near Seattle.

    • The world's most important industries are iron and steel, textiles, automobiles, petrochemicals and electronics.

    Map Work

  • Locate Silicon Valley (San Francisco) and Silicon Forest (Seattle).
  • Mark the traditional industrial cores: the UK, north-eastern USA and Western Europe.
  • Mark the countries with large small-scale sectors: India, China, Indonesia and Brazil.

    • Key-Facts Sheet

  • Manufacturing concentrations cover less than 10% of the world's land.
  • Market access is the most important location factor.
  • Aluminium locates near energy.
  • Large-scale manufacturing is about 200 years old.
  • Two technopoly examples are Silicon Valley and Silicon Forest.

    • Board Exam Focus

    MCQs in the exercises:

  • The wrong statement is "Sugar, cotton textiles and vegetable oils are footloose industries". These are raw-material or agro-based industries.
  • Factors of production are owned individually in a capitalist economy.
  • Basic industries produce raw materials for other industries.

    • Outline: Footloose industries (30 words).

  • Not tied to a raw material; use components available anywhere.
  • Small output and workforce.
  • Non-polluting.
  • Located by road accessibility.

    • Outline: Why do high-tech industries prefer the peripheries of metropolitan centres?

  • Planned business parks with low, dispersed buildings rather than massive factories.
  • Road access.
  • Proximity to skilled white-collar workers and R and D.
  • Regional development schemes.

    • Outline: Africa is resource-rich yet industrially backward.

  • Relate the location factors: market purchasing power, transport, energy, capital and technology.
  • Note that manufacturing concentrates where these exist, on less than 10% of land.

    • Key Terms

  • Secondary activity (द्वितीयक क्रियाकलाप): an activity that adds value to raw materials.
  • Manufacturing (विनिर्माण): transforming raw materials into higher-value goods.
  • Mass production (वृहत् उत्पादन): standardised parts in large quantity.
  • Automation (स्वचालन): the advanced stage of mechanisation.
  • Agglomeration economies (समूहन मितव्ययिताएँ): savings from linked industries.
  • Footloose industry (स्वच्छंद उद्योग): an industry not tied to raw material.
  • Cottage industry (कुटीर उद्योग): the household unit.
  • Basic industry (आधारभूत उद्योग): an industry that supplies other industries.
  • Consumer goods industry (उपभोक्ता वस्तु उद्योग): an industry that makes goods for direct use.
  • Agri-business (कृषि व्यापार): industrial-scale farming.
  • Joint sector (संयुक्त क्षेत्र): public-private partnership.
  • High-tech industry (उच्च प्रौद्योगिकी उद्योग): R and D intensive industry.
  • Technopolis (टेक्नोपोलिस): a high-tech cluster.

    • Common Mistakes

  • Listing sugar or cotton textiles as footloose. They depend on raw material.
  • Saying raw material is the most important location factor. The book says market access is.
  • Confusing basic industries with consumer goods industries.
  • Treating "industry" and "manufacturing" as always identical. The book uses "manufacturing industry" because tourism and entertainment are also called industries.
  • Saying high-tech industries are dominated by blue-collar workers. White-collar professionals outnumber them.

    • 💡 Key Learning Points

    • ✓Explain how secondary activities add value to raw materials, and define manufacturing and manufacturing industry.
    • ✓List the characteristics of modern large-scale manufacturing.
    • ✓Analyse the location factors, with market access as the most important, and describe footloose industries.
    • ✓Classify industries by size, inputs, output and ownership with textbook examples.
    • ✓Describe high-tech industries and technopolies such as Silicon Valley and Silicon Forest.

    👨‍🏫 Teaching Tips

    • →Start with the cotton-to-yarn and ore-to-steel examples, and have students trace value addition for a product in the classroom.
    • →Draw Fig. 5.1 as a mind map on the board with four branches: size, inputs, output and ownership.
    • →Give a location-factor case game: students decide where to place an aluminium plant, a sugar mill and a software firm, and justify it.
    • →Contrast the 2.5 sq km corn belt example with a factory estate to show the intensity of manufacturing.
    • →Discuss footloose industries by asking why a mobile-accessory unit can be set up almost anywhere with road access.
    • →Show images of Silicon Valley campuses versus steel plants to illustrate the high-tech landscape.
    • →Practise the Africa 150-word answer as a group, linking each location factor to the continent.
