Manufacturing Industries Important Extra Questions Long Answer Type
Question 1.
Or
Explain five main geographical factors influencing location of industries giving suitable examples from Indian industries.
Or
Why do large scale industries choose different location? Explain any four factors which influence the industrial location.
Answer:
Manufacturing. Manufacturing is a secondary process of transforming raw materials into finished products. The raw materials of agriculture, forests, minerals are changed into new products. For example, clay is changed into pottery, timber is changed into furniture, etc.These manufactured goods are more useful and valuable than the raw material. The location of manufacturing industries depends on a number of physical and socio-economic factors. These factors are called the basis of industries. No single factor decides the location of industries.
Geographical Factors
(1) Nearness to raw materials. Large quantities of raw materials are needed for industries. Therefore, industries are located near the source of raw materials. The industries are located near mines, forests, farms and seas. It saves the cost of transportation. Sugar mills are located in the areas where sugarcane is produced. Iron and steel industry uses bulky raw materials.
Steel centres are developed where coal and iron are easily available. Industries producing perishable goods (meat, fish and dairy products) are located near the areas of their production. Example. Jute mills in West Bengal and Cotton Textile mills in Maharashtra are located due to the availability of the raw materials.
(2) Power resources. Coal, oil and water-power are the main sources of power. Most of the industries are located around coal-fields. The industrial regions of Damodar Valley (India), Ruhr Valley (West Germany) depends upon coal. Some industries use large amount of electricity.
Such industries like Chemical Industries, Aluminium Industries and Paper Industry are located near hydro-electric stations. Petro-chemical Industries use large quantities of Petroleum. Example. Iron and Steel centres in India are located near Jharia and Raniganj coal fields. Chemical fertiliser plant is located at Nangal where cheap water power is available from Bhakra Project.
(3) Means of Transportation. Modern industries need cheap, developed and quick means of transportation. Water-transport is the cheapest means of transport. Cheap means of transportation are required for the movement of workers, raw materials and machinery to the factories. Manufactured goods should be sent to the market at low cost. Example. Delhi is the nodal point of transport and industries concentrated around it.
(4) Climate. Stimulating climate increases the efficiency of the labourers. Certain industries require special type of climate. Cotton Textile industry requires humid climate, Film industry needs good weather with clear blue sky. Areas with favourable climate become huge markets.
Example. Mumbai is the leading centre of Cotton Textile due to wet coastal climate. Dry climate has led to the location of Aircraft Industry at Bengaluru (India) and California (U.S.A.).
Non-Geographical factors
(5) Cheap land. Heavy industries need cheap level land. Steel industry at Jamshedpur is located in a broad river-valley.
(6) Capital. Large amount of capital is invested in many industries. Many industries have been located in big cities like Delhi, Mumbai, Kolkata. Many banks and companies provide capital in these areas.
(7) Skilled labour. Cheap and skilled labour is essential for the location of the industries. Areas of dense population provide cheap and large labour force. Engineering industries need skilled labour. Cotton Textile industry in Lancashire, Glass industry in Ferozabad, Sports goods industry in Jalandhar are located due to the availability of the skilled labour. The Swiss are known for watch making, the British for specialised cotton textiles, the Japanese for electronic goods and Varanasi is known for Silk embroidery.
(8) Government policies. Most of the industries are located with government aid. Government policies may encourage or discourage the industries in an area. Government may offer cheap land, reduce taxes, help in providing machinery and transport. Bhilai and Rourkela tea plants were set up to develop tribal area.
(9) Nearness to market. Industries are located near the market for their manufactured goods. Urban and industrial centres with dense population provide a large market. Market is based on demand and the purchasing power of the people. Countries of Asia do not make a huge market because the people cannot afford to buy goods. Dairy Industry is located near the ready markets of towns. Light Engineering industries are located near the big factories which require these goods.
(10) Early start. Momentum of an early start leads to the location of an industry such as cotton textile in Mumbai.
(11) Defence. Some industries are located with a military motive such as Aircraft industry at Bengaluru.
(12) Historical Factors. Historical accident may bring an industry to a new location such as Automobile Industry at Detriot in U.S.A., Lock Industry at Aligarh.
(13) Other Factors. Some secondary factors also help in the location of industries such as availability of water, technical knowledge, political factors, etc. The location of industries keep on changing. A good location, today may become a bad location tomorrow.
