05.    INDUSTRIES

Secondary activities or manufacturing change raw materials into products of more value to people.

Industry refers to an economic activity that is concerned with production of goods, extraction of minerals or the provision of services. Thus, we have 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 of raw materials, size and ownership.

Raw Materials: Industries may be agro based, mineral based, marine based and forest based depending on the type of raw materials they use.

· Agro based industries use plant and animal-based products as their raw materials. Food processing, vegetable oil, cotton textile, dairy products and leather industries are examples of agro-based industries.

· Mineral based industries are primary industries that use mineral ores as their raw materials. The products of these industries feed other industries. Iron made from iron ore is the product of mineral based industry. This is used as raw material for the manufacture of a number of other products, such as heavy machinery, building materials and railway coaches.

· Marine based industries use products from the sea and oceans as raw materials. Industries processing sea food or manufacturing fish oil are some examples.

· Forest based industriesutilize forest produce as raw materials. The industries associated with forests are pulp and paper, pharmaceuticals, furniture and buildings.

Size:  It refers to the amount of capital invested, number of people employed and the volume of production. Based on size, industries can be classified into

·       small scale industries. Silk weaving and food processing industries, Cottage or household industries are a type of small-scale industry where the products are manufactured by hand, by the artisans. Basket weaving, pottery and other handicrafts are examples of cottage industry. Small scale industries use lesser amount of capital and technology as compared to large scale industries that produce large volumes of products.

·       Investment of capital is higher and the technology used is superior in large scale industries. Production of automobiles and heavy machinery are large scale industries.

Ownership: Industries can be classified into private sector, state owned or public sector, joint sector and cooperative sector.

·       Private sectorindustries are owned and operated by individuals or a group of individuals.

·       The public sector industries are owned and operated by the government, such as Hindustan Aeronautics Limitedand Steel Authority of India Limited.

·       Joint sector industries are owned and operated by the state and individuals or a group of individuals. Maruti Udyog Limited is an example of joint sector industry.

·       Co-operative sector industries are owned and operated by the producers or suppliers of raw materials, workers or both. Anand Milk Union Limited and Sudha Dairy are a success stories of a co-operative venture.

FACTORS AFFECTING LOCATION OF INDUSTRIES

The factors affecting the location of industries are the availability of raw material, land, water, labour, power, capital, transport and market. Industries are situated where some or all of these factors are easily available.

Sometimes, the government provides incentives like subsidised power, lower transport cost and other infrastructure so that industries may be located in backward areas. Industrialisation often leads to development and growth of towns and cities.

Industrial System- An industrial system consists of inputs, processes and outputs.

·       The inputs are the 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. In case of the textile industry the inputs may be cotton, human labour, factory and transport cost. The processes include ginning, spinning, weaving, dyeing and printing. The output is the shirt you wear.

Industrial regions Industrial regions emerge when a number of industries locate close to each other and share the benefits of their closeness.

·       Major industrial regions of the world are eastern North America, western and central Europe, eastern Europe and eastern Asia 

·       Majorindustrial regions tend to be located in the temperate areas, near sea ports and especially near coal fields.

·       India has several industrial regions like 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. The countries in which iron and steel industry is located are Germany, USA, China, Japan and Russia.

·       Textile industry is concentrated in India, Hong Kong, South Korea, Japan and Taiwan.

·       The major hubs of Information technology industry are the Silicon valley of Central California and the Bangalore region of India.

IRON AND STEEL INDUSTRY-This is a feeder industry whose products are used as raw material for other industries. The inputs for the 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.

·       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.

·       Steel is often called the backbone of modern industry. Almost everything we use is either made of iron or steel or has been made with tools and machinery of these metals. Ships, trains, trucks, and autos are made largely of steel. Even the safety pins and the needles you use are made from steel. Oil wells are drilled with steel machinery. Steel pipelines transport oil. Minerals are mined with steel equipment. Farm machines are mostly steel. Large buildings have steel framework.

·       Suitable location for iron and steel industry

Before 1800 A.D. iron and steel industry was located where raw materials, power supply and running water were easily available. Later 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. This is because by this time steel works had become very large and iron ore had to be imported from overseas.

Location in India:In India, iron and steel industry has developed takingadvantage of raw materials, cheap labour, transport and market. All the important steel producing centres such as Bhilai, Durgapur, Burnpur, Jamshedpur, Rourkela, Bokaro are situated in a region that spreads over four states — West Bengal, Jharkhand, Odisha and Chhattisgarh. Bhadravati and Vijay Nagar in Karnataka, Vishakhapatnam in Andhra Pradesh, Salem in Tamil Nadu are other important steel centresutilising local resources.

JAMSHEDPUR

·       Before 1947, there was only one iron and steel plant in the country – Tata Iron and Steel Company Limited (TISCO). It was privately owned. After Independence, the government took the initiative and 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 onSakchi was renamed as Jamshedpur. Geographically, Jamshedpur is the most conveniently situated iron and steel centre in the country.

·       Sakchi was chosen to set up the steel plant for several reasons. 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.

·       In Jamshedpur, several other industrial plants were set up after TISCO. They produce chemicals, locomotive parts, agricultural equipment, machinery, tinplate, cable and wire.

 

PITTSBURGH:

·       It is an important steel city of the United States of America. The steel industry at Pittsburgh enjoys locational advantages.

·       Some of 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 is one of the world’s best routes for shipping ore cheaply – the famous Great Lakes waterway.

·       Trains carry the ore from the Great Lakes to the Pittsburgh area. The Ohio, the Monogahela and Allegheny rivers provide adequate water supply.

·       The Pittsburgh area has many factories other than steel mills. These 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 used in them.

·       Fibres are the raw material of textile industry. Fibres can be natural or man-made. Natural fibres are obtained from wool, silk, cotton, linen and jute. Man madefibres include nylon, polyester, acrylic and rayon.

·       The cotton textile industry is one of the oldest industries in the world. Till the industrial revolution in the 18th century, 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 in other parts of the world. Today India, China, Japan and the USA are important producers of cotton textiles.

·       India has a glorious tradition of producing excellent quality cotton textiles. Before the British rule, Indianhand spun and hand woven cloth already had a wide market.

·       The Muslins of Dhaka, Chintzes of Masulipatnam, Calicos of Calicut and Gold-wrought cotton of Burhanpur, Surat and Vadodara were known worldwide for their quality and design.

Decline of the hand woven cotton textile-The production of hand woven cotton textile was expensive and time consuming. Hence, 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. The warm, moist climate, a port for importing machinery, availability of raw material and skilled labour resulted in rapid expansion of the industry in the region.

·       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 partsof India.

·       Coimbatore, Kanpur, Chennai, Ahmedabad, Mumbai, Kolkata, Ludhiana, Puducherry and Panipat are some of the other important centres.

 

 

 

AHMEDABAD :

·       It is located in Gujarat on the banks of  the Sabarmati river. The first mill was established in 1859. It soon became the second largest textile city of India, after Mumbai. Ahmedabad was therefore often referred to as the ‘Manchester of India’.

·       Why Ahmedabad?- It is situated very close to cotton growing area. This 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.

OSAKA :

·       It is an important textile centre of Japan, also known as the ‘Manchester of Japan’.

·       Why Osaka?-The textile industry developed in Osaka due to several geographical factors. 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  riverYodo  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.

INFORMATION TECHNOLOGY (IT)

·       The information technology industry deals in the storage, processing and distribution of information. Today, this industry has become global. This is due to a series of technological, political, and socio-economic events.

·       The main factors guiding the location of these industries are resource availability, cost and infrastructure.

·       The major hubs of the IT industry are the Silicon Valley, California and Bengaluru, India.

·       Bengaluru is located on the Deccan Plateau from where it gets the name ‘Silicon Plateau’. The city is known for its mild climate throughout the year. Silicon Valley, is a part of Santa Clara Valley, located next to the Rocky Mountains of North America. The area has temperate climate with the temperatures rarely dropping below 0 degrees centigrade.

·       Other cities such as Gurgaon, Pune, Thiruvanthapuram, Kochi and Chandigarh are also important centres of the IT industry. However, Bengaluru has always had a unique advantage, as a city with highest availability of middle and top management talent.
