Introduction
• Secondary activities or manufacturing change raw materials into products of more value to people.
→ Example: Pulp changed into paper and paper into a note book.
• Industry refers to an economic activity that is concerned with production of goods, extraction of minerals or the provision of services.
→ Example: Iron and steel industry (production of goods), coal mining industry (extraction of coal) and tourism industry (service provider).
Classification of Industries
• Industries can be classified on the basis:
→ Raw materials
→ Size
→ Ownership
• On the Basis of Raw Materials:
→ Agro based industries: Use plant and animal based products as their raw materials. Examples: Food processing, vegetable oil, cotton textile, dairy products and leather industries.
→ Mineral based industries: Use mineral ores as their raw materials. The products of these industries feed other industries. Example: Iron made from iron ore.
→ Marine based industries: Use products from the sea and oceans as raw materials. Examples: Industries processing sea food or manufacturing fish oil.
→ Forest based industries: Use forest produce as raw materials. Examples: pulp and paper, pharmaceuticals, furniture and buildings.
• On the Basis of Size (refers to the amount of capital invested, number of people employed and the volume of production):
→ Small Scale industries: Use lesser amount of capital and technology. Example: Cottage or household industries where the products are manufactured by hand, by the artisans. Basket weaving, pottery and other handicrafts are products of cottage industry.
→ LargeScale industries: Use higher capital is higher and superior technology. Examples: Silk weaving and food processing industries.
• On the basis of Ownership:
→ Private Sector industries: Owned and operated by individuals or a group of individuals. Examples: Reliance Industries Limited and ITC Limited.
→ Public sector industries: Owned and operated by the government. Examples: Hindustan Aeronautics Limited and Steel Authority of India Limited.
→ Joint sector industries: Owned and operated by the state and individuals or a group of individuals. Example: Maruti Udyog Limited.
→ Co-operative sector industries: Owned and operated by the producers or suppliers of raw materials, workers or both. Examples: Anand Milk
Union Limited and Sudha Dairy.
Factors affecting location of Industries
• The factors affecting the location of industries areavailability of:
→ Raw material
→ Land
→ Water
→ Labour
→ Power
→ Capital
→ Transport
→ Market
• Sometimes, the government provides incentives like subsidised power, lower transport cost and other infrastructure so that industries may be located in backward areas.
Industrial System
• An industrial system consists of inputs, processes and outputs.
→ Inputs include raw materials, labour and costs of land, transport, power and other infrastructure.
→ The processes include a wide range of activities that convert the raw material into finished products.
→ The outputs are the end product and the income earned from it.
Industrial Regions
• When a number of industries locate close to each other and share the benefits of their closeness, they make a Industrial regions.
• Industrial regions of the world: eastern North America, western and central Europe, eastern Europe and eastern Asia.
• Industrial regions in India: Mumbai- Pune cluster, Bangalore-Tamil Nadu region, Hugli region, Ahmedabad-Baroda region, Chottanagpur industrial belt, Vishakhapatnam-Guntur belt, Gurgaon-Delhi-Meerut region and the Kollam-Thiruvanathapuram industrial cluster.
Distribution of Major Industries
• The world’s major industries are the iron and steel industry, the textile industry and the information technology industry.
• The iron and steel and textile industry are the older industries while information technology is an emerging industry.
Iron and Steel Industry
• This is a feeder industry whose products are used as raw material for other industries.
• The inputs for this industry include raw materials such as iron ore, coal and limestone, along with labour, capital, site and other infrastructure.
• The process of converting iron ore into steel involves many stages.
→ The raw material is put in the blast furnace where it undergoes smelting.
→ It is then refined.
• The output obtained is steel which may be used by other industries as raw material.
Iron and Steel
• Steel is often called the backbone of modern industry.
→ Daily use tools, Ships, trains, trucks, and autos are made largely of iron or steel.
• Features of Steel:
→ Steel is tough and it can easily be shaped, cut, or made into wire.
→ Special alloys of steel can be made by adding small amounts of other metals such as aluminium, nickel, and copper.
→ Alloys give steel unusual hardness, toughness, or ability to resist rust.
Timeline of Iron and Steel industry’s location
• Before 1800 A.D. iron and steel industry was located where raw materials, power supply and running water were easily available.
• Between 1850 to 1900 A.D., the ideal location for the industry was near coal fields and close to canals and railways.
• After 1950, iron and steel industry began to be located on large areas of flat land near sea ports because by this time steel works had become very large and iron ore had to be imported from overseas.
• Location of iron and steel industry in the world: Germany, USA, China, Japan and Russia.
• Location of iron and steel industry in India: Bhilai (Chhattisgarh), Durgapur, Burnpur (West Bengal), Rourkela (Odisha), Bokaro, Jamshedpur (Jharkhand).
• Other important steel centres: Bhadravati and Vijay Nagar in Karnataka, Vishakhapatnam in Andhra Pradesh, Salem in Tamil Nadu.
Jamshedpur
• Before independence, Tata Iron and Steel Company Limited (TISCO) was only one iron and steel plant in the country which was privately owned.
• After Independence, the government set up several iron and steel plants.
→ TISCO was started in 1907 at Sakchi, near the confluence of the rivers Subarnarekha and Kharkai in Jharkhand. Later on, Sakchi was renamed as Jamshedpur.
Why Sakchi was chosen to set up the steel plant
• This place was only 32 km away from Kalimati station on the Bengal-Nagpur railway line.
• It was close to the iron ore, coal and manganese deposits as well as to Kolkata, which provided a large market.
• TISCO, gets coal from Jharia coalfields, and iron ore, limestone, dolomite and manganese from Odisha and Chhattisgarh.
• The Kharkai and Subarnarekha rivers ensured sufficient water supply. Government initiatives provided adequate capital for its later development.
Pittsburgh
• It is an important steel city of the United States of America.
Why iron and steel industry developed in Pittsburgh
• The raw material such as coal is available locally, while the iron ore comes from the iron mines at Minnesota, about 1500 km from Pittsburgh.
→ Between these mines and Pittsburgh, Great Lakes waterway is present which is one of the world’s best routes for shipping ore cheaply.
→ Trains carry the ore from the Great Lakes to the Pittsburgh area.
→ The Ohio, the Monogahela and Allegheny rivers provide adequate water supply.
• Today,, Large steel mills are located in the valleys of the Monogahela and Allegheny rivers above Pittsburgh and along the Ohio River below it.
• Finished steel is transported to the market by both land and water routes.
• Other factories present in Pittsburgh area use steel as their raw material to make many different products such as railroad equipment, heavy machinery and rails.
Cotton Textile Industry
• The textile industry can be divided on the basis of raw materials i.e., fibres used in them.
• Fibres can be of two types:
→ Natural: Obtained from wool, silk, cotton, linen and jute.
→ Man-made: It includes nylon, polyester, acrylic and rayon.
• Till the industrial revolution, cotton cloth was made using hand spinning techniques (wheels) and looms.
• In 18th century, power looms facilitated the development of cotton textile industry, first in Britain and later spread to other parts of the world.
• Important producers of cotton textiles: India, China, Japan and the USA.
• Before the British rule, Indian hand spun and hand woven cloth popular worldwide for their quality and design but the production of hand woven cotton textile was expensive and time consuming.
→ However, the traditional cotton textile industry could not face the competition from the new textile mills of the West, which produced cheap and good quality fabrics through mechanized industrial units.
• The first successful mechanized textile mill was established in Mumbai in 1854.
• Location of cotton textile industry in India:
→ Initially this industry flourished in the states of Maharashtra and Gujarat because of favourable humid climate.
→ But today, humidity can be created artificially, and raw cotton is a pure and not weight losing raw
material, so this industry has spread to other parts of the country such as Coimbatore, Kanpur, Chennai, Ahmedabad, Mumbai, Kolkata, Ludhiana, Puducherry and Panipat.
Ahmedabad
• It is located in Gujarat on the banks of the Sabarmati river.
• The first mill was established in 1859 after Mumbai.
• It soon became the second largest textile city of India, after Mumbai and was therefore often referred to as the ‘Manchester of India’.
Why textile industry developed in Ahmedabad
• Ahmedabad is situated very close to cotton growing area which ensures easy availability of raw material.
• The climate is ideal for spinning and weaving.
• The flat terrain and easy availability of land is suitable for the establishment of the mills.
• The densely populated states of Gujarat and Maharashtra provide both skilled and semi-skilled
labour.
• Well developed road and railway network permits easy transportation of textiles to different parts of the country, thus providing easy access to the market.
• Mumbai port nearby facilitates import of machinery and export of cotton textiles.
• But in the recent years, Ahmedabad textile mills facing problems.
→ Several textile mills have closed down due to the emergence of new textile centres in the country as well as non-upgradation of machines and technology in the mills of Ahmedabad.
Osaka
• It is an important textile centre of Japan, also known as the ‘Manchester of Japan’.
Why textile industry developed in Osaka
• The extensive plain around Osaka ensured that land was easily available for the growth of cotton mills.
• Warm humid climate is well suited to spinning and weaving.
• The river Yodo provides sufficient water for the mills.
• Labour is easily available.
• Location of port facilitates import of raw cotton and for exporting textiles.
• The textile industry at Osaka depends completely upon imported raw materials.
→ Cotton is imported from Egypt, India, China and USA.
• The finished product is mostly exported and has a good market due to good quality and low price.
• Recently, the cotton textile industry of Osaka has been replaced by other industries, such as iron and steel, machinery, shipbuilding, automobiles, electrical equipment and cement.
Information Technology (IT)
• The information technology industry deals in the storage, processing and distribution of information.
• This industry has become global due to a series of technological, political, and socio-economic events.
• Major hubs of the IT industry of the world: Silicon Valley, California and Bangalore, India.
• There are other emerging information technology hubs in metropolitan centres of India such as Mumbai, New Delhi, Hyderabad and Chennai.
→ Other cities such as Gurgaon, Pune, Thiruvanthapuram, Kochi and Chandigarh re also important centres of the IT industry.
