Industries (NCERT Class 8 Geography Chapter 5)
World Industrial Region/
Manufacturing (Secondary Activities) changes raw materials into products of a much greater value for people. Industry refers to the economic actitivty concerned with extraction of minerals or raw material, production of finished goods and provision of services. Thus we have iron industry (extraction), steel industry (production) and tourism industry (service).

Classification of Industry
On the basis of Raw Materials,
  1. Agro based industries uses plant and animal based products as their raw material. Example, food processing, dairy product, cotton industry, meat and poultry industry and leather industry.
  2. Mineral based industries uses mineral ores as their base raw material. Example, Coal, Iron and Petroleum. Mineral based industries provide finished products to other industries. For example, iron industry provide iron for steel, railways, construction and other industries.
  3. Marine based industries uses raw materials extracted from sea and oceans. For example, sea food and fish oil industry.
  4. Forest based industries uses forest based products as their raw materials. Example, paper, pharmaceuticals, furniture and construction industry.

On the basis of Size,
  1. Small scale industries require low capital investment and technology. It can be started by employing a small group of people and it is labour intensive. Handicraft and Silk industries are the prime example of small scale industries.
  2. Large scale industries require high amount of capital and technology. A large number of men and women need to be employed. It is technology driven and known for large productions. Automobile and heavy machinery industries are the suitable examples of the large scale industries.

On the basis of ownership,
  1. Public or State owned Industries are those industries which are owned exculusively by the Government. Hindustan Aeronautics Limited, Antrix Limited, Steel Authority of India Limited are examples of public sector companies.
  2. Private sector industries are those industries which are owned by an individual or a group of individuals. Tata Steel, Mahindra, Google and Microsoft are examples of private sector companies.
  3. Joint sector industries are those industries which are jointly owned by the state and individual or group of individuals. Maruti Udyog Limited is an example of joint sector company.
  4. Co-operative sector industries are those industries which are operated and owned by suppliers of raw materials. Anand Milk Union Limited (AMUL) and Sudha Dairy are prime examples of co-operative sector companies.

Factors Affecting Location of Industries
1. availability of raw material
2. land
3. water
4. labour
5. power
6. capital
7. transport
8. market
9. government subsidies

Industrial System
  1. It consists of inputs, processes and output.
  2. Inputs are raw materials, labour and costs of land, transport and power.
  3. Processes include activities which convert raw material into finished product.
  4. Outputs are end product and income.
  5. In case of textitle industry, inputs are cotton, human labour, factory and transport cost; processes include ginning, spinning, weaving, dyeing and printing; and outputs are shirt and economic benefit to people involved in making of shirt.

Industrial Regions
  1. An industrial region emerge when a number of industries setup near to each other and reaps mutual economic benefits.
  2. Some of the heaviest industrialized regions of the world area North America, Europe and Asia.
  3. These are usually found in temperate regions near coal fields and sea ports.
  4. Mumbai-Pune industrial cluster, Bangalore-Tamil Nadu region, Hugli region, Ahmedabad-Baroda region, Chottanagpur industrial belt, Vishakhapatnam-Guntur belt, Gurgaon-Delhi-Meerut region and the Kollam-Thiruvanathapuram cluster are some of the most important industrial regions in India.

Distribution of Major Industries
  1. Iron and steel, textile and information technology (IT) are some of the major industries of the world.
  2. Iron and steel and textile are examples of old and conventional industries whereas IT along with Wellness and Hospitality are new and emerging industries. Emerging industries are also known as sunshine industries.

IndustryMajor Hubs

Iron and Steel Industry
Iron and Steel industry is known as the feeder industry. It is known as the backbone of the modern industrial system. Its finished products are used as raw material in other industry.
It follow smilar industrial system of input, processes and output.

ProcessComponent
InputRaw material (iron ore, coal and limestone), labour, capital, site and other infrastructure
ProcessConversion of iron ore into iron and steel
OutputIron and Steel

One tonne of steel requires 8 tonnes of coal, 4 tonnes of iron ore and 1 tonne of limestone on average.
On addition of small amounts of materials such copper, nickel and aluminium, iron and steel forms alloys. Alloys have unusual hardness, toughness, and ability to resist rust.

Ideal Location for Iron and Steel Industry
  1. Before 1800, the ideal site for iron and steel industry was located where materials, power supply and running water were readily available.
  2. From 1800 to 1950, a place near coal industry with good canal or railways connectivity became the ideal site for the industry.
  3. From 1950, iron and steel industries shifted to sea ports due to their scale they need to import coal from other countries.

Iron and Steel Industry in India
  1. In India, iron and steel indusrty is flourishing because of avaialability of raw materials, cheap labour, transport and market.
  2. Bhilai, Durgapur, Burnpur, Jamshedpur (Jharkhand), Rourkela, Bokaro, Vijay Nagar (Karnataka), Vishakhapatnam (Andhra Pradesh), Salem (Tamil Nadu) are important centres of iron and steel industries in India.

Jamshedpur
  1. Tata Iron and Steel Company Limited (TISCO) is the first and only pre-independece steel producer in India.
  2. It was started by Jamshedji Tata in 1907 at Sakchi, near confluence of Subarnarekha and Kharkai rivers in Jharkhand. It is a privately owned company.
  3. Sakchi was later renamed Jamshedpur after the founder of TISCO, Jamshedji Tata.
  4. Jamshedpur (Sakchi) was chosen for TISCO for several reasons. These are 1. Closeness to Kalamati Station of Bengal-Nagpur Railway Line, 2. Closeness to iron ore, coal, limestone, dolomite and manganese deposit fields, 3. water supply from Kharkai  and  Subarnarekha rivers, and 4. closeness to Kolkata.
  5. Several other industries were setup in Jamshedpur after TISCO. They produce chemicals, locomotive parts, agricultural equipment, heavy machinery,   cable and wire.
  6. Indian iron and steel industry cosists of both large steel plants and mini steel mills along with secondary producers, rolling mills and ancillary industries.
