• Removing restrictions and obstacles to the entry of multinational companies in India.
• Allowing Indian companies to enter into foreign collaboration in India and also encouraging them to set up joint venture’s abroad.
• Carrying out massive import liberalization programmes by switching over from quantitative restrictions to tariffs in the first place, and then bringing down the level of import duties considerably.
• Instead of a set of export incentives, opting for exchange rate adjustments for promoting export.

Q5.Why there is spatial variation in FDI in India?
Answer:
Major share of both domestic investment as well as foreign direct investment went to already developed states. For example, out of the total proposed investment by the industrial entrepreneurs during 1991-2000 nearly one fourth (23 per cent) was for industrially developed Maharashtra, 17 per cent for Gujarat, 7 per cent for Andhra Pradesh, and about 6 per cent for Tamil Nadu while Uttar Pradesh, the state with the largest population has only 8 per cent. In spite of several concessions, seven north-eastern states could get less than 1 per cent of the proposed investment. In fact, economically weaker states could not compete with the developed states in open market in attracting industrial investment proposals and hence they are likely to suffer from these processes.

Q6.How are industrial regions distributed in our country? List the indices used to identity them.

Q8.Why are most of sugar mills established in sugarcane producing areas?
OR
Why are the sugarcane industries located within the cane producing areas?
Answer:
Most of sugar mills are established in sugarcane producing areas because:

• Sugarcane is a weight-losing crop. The ratio of sugar’to sugarcane varies between 9 to 12 per cent depending on its variety. Its sucrose content begins to dry during haulage after it has been harvested from the field.
• Better recovery of sugar is dependent upon its being crushed within 24 hours of its harvesting.

Q9.Why iron and steel industry is located in peninsular plateau?
Answer:
Iron and steel plant requires raw materials which are weight losing, heavy & bulky therefore its location is influenced by: ‘

• Raw Materials: Iron ore, coal, limestone, dolomite, manganese are weight losing and therefore, industries should be located near the source of raw materials.
• Cost: Industry should be located at place where the cost of assembling and the raw material and distribution of finished product is the lowest. Some steel plants are located near coal fields and iron ore producing areas.
• Transport: All ’ the plants are located on the trunk rail routes which connects them to large urban market.All these conditions are favorable as peninsular India and hence iron and steel is locked there.

Long Answer Type Questions:

Q1.Why most of the iron and steel industries are located in the Chhotanagpur plateau?
Answer:
This region extends over Jharkhand, northern Odisha and western West Bengal and is known for the heavy metallurgical industries.
This region owes its development to the discovery of coal in the Damodar Valley and metallic and non-metallic minerals in Jharkhand and northern Odisha. Proximity of coal, iron ore and other minerals facilitated the location of heavy industries in this region. Six large integrated iron and steel plants at Jamshedpur, Burnpur- Kulti, Durgapur, Bokaro and Rourkela are located within this region.

To meet the power requirement, thermal and hydroelectric plants have been constructed in the Damodar Valley. This region is well connected to the transportation network between the metros of Mumbai and Kolkata and water ways. Water for the plants is easily available from Subarnarekha and it’s tributary. Kolkata port is nearby. Densely populated surrounding regions provide cheap labour and Hugli region provides vast market for its industries. Heavy engineering, machine tools, fertilisers, cement, paper, locomotives and heavy electricals are some of the important industries in this region. Important centres are Ranchi, Dhanbad, Chaibasa, Sindri, Hazaribag, Jamshedpur, Bokaro, Rourkela, Durgapur, Asansol and Dalmianagar.

Q2.Explain different phases of development of cotton industry in India.
Answer:
The cotton textile industry is one of the traditional industries of India. In the ancient and the medieval times, it used to be only a cottage industry. India was famous worldwide for the production of muslin, a very fine variety of cotton cloth, calicos, chintz and other different varieties of fine cotton cloth.

Initially, the British did not encourage the development of the indigenous cotton textile industry. They exported raw cotton to their mills in Manchester and Liverpool and brought back instead the finished products to be sold in India. In 1854, the first modern cotton mill was established in Mumbai. Subsequently, two more mills, the Shahpur Mill and the Calico Mill were established in Ahmedabad. By 1947, the number of mills in India went up to 423 but the scenario changed after partition, and this industry suffered a major recession.

After independence India was left with 409 mills and only 29 per cent of the cotton producing areas. After Independence, this industry gradually recovered and eventually flourished. After 1921, with the development of the railway network other cotton textile centres expanded rapidly. In southern India, mills were set up at Coimbatore, Madurai and Bangalore. In Central India, Nagpur, Indore, Solapur and Vadodara became cotton textile centres. Cotton textile mills were set up at Kanpur based on local investment.

Tamil Nadu has the largest number of mills and most of them produce yarn rather than cloth. Coimbatore has emerged as the most important centre with nearly half the mills located there. Chennai, Madurai, Tirunelveli, Tuticorin, Thanjavur, Ramanathapuram and Salem are the other important centres. In Karnataka, the cotton textile industry has developed in the cotton producing areas in the north-eastern part of the state. Davangere, Hubli, Bellary, Mysore and Bangalore are important centres. In Andhra Pradesh, the cotton textile industry is located in the cotton producing Telangana region, where most of the mills are spinning mills producing yarn. The important centres are Hyderabad, Secunderabad, Warangal and Guntur. In Uttar Pradesh, Kanpur is the largest centre. Some of the other important centres are Modinagar, Hathras, Saharanpur, Agra and Lucknow. In West Bengal, the cotton mills are located in the Hugli region.

Q3.Explain different phases of development of petrochemical industry in India.
Answer:
Many items are derived from crude petroleum, which provide raw materials for many new industries, these are collectively known as petrochemical industries.
This group of industries is divided into four sub-groups:

• Polymers
• Synthetic fibres
• Elastomers
• Surfactant intermediate

Three organisations are working in the petrochemical sector under the administrative control of the Department of Chemicals and Petrochemicals.

• Indian Petrochemical Corporation Limited (IPCL) is a public sector undertaking. It is responsible for the manufacture and distribution of various petrochemicals like polymers, chemicals, fibres and fibre intermediates.
• Petrofils Cooperative Limited (PCL) is a joint venture of the Government of India and Weaver’s Cooperative Societies.
• Central Institute of Plastic Engineering and Technology (CIPET), involved in imparting training in petrochemical industry.

Polymers are made from ethylene and propylene. These materials are obtained in the process of refining crude oil. Polymers are used as raw materials in the plastic industry. The National Organic Chemicals Industries Limited (NOCIL), established in private sector in 1961, started the first naphtha based chemical industry in Mumbai. The plants located at Mumbai, Barauni, Mettur, Pimpri and Rishra are the major producers of plastic materials. Synthetic fibres are widely used in the manufacturing of fabrics because of their inherent’ strength, durability, washability, and resistance to shrinkage. Industries manufacturing nylon and polyester yarns are located at Kota, Pimpri, Mumbai, Modinagar, Pune, Ujjain, Nagpur and Udhna. Acrylic staple fibre is manufactured at Kota and Vadodara.

Q4.Write a detailed note on Hugli industrial area.
Answer:
It is located along the Hugli river.
Extension: This region extends from Bansberia in the north to Birlanagar in the south for a distance of about 100 km. Industries also have developed in Mednipur in the West Kolkata-Howrah from the nucleus of this industrial region.

Development: Historical, geographical, economic and political factors have contributed much to its development. It developed with the opening of river port on Hugli. Kolkata emerged as a leading centre of the country. Later, Kolkata was connected with interior parts by railway lines and road routes. Development of tea plantations in Assam and northern hills of West Bengal, the processing of indigo earlier and jute later coupled with the opening of coalfields of the Damodar Valley and iron ore deposits of the Chotanagpur plateau, contributed to the industrial development of the region.

Labour: Cheap labour available from thickly populated part of Bihar, eastern Uttar Pradesh and Odisha also contributed to its development. Kolkata, being the capital city of British India (1773-1911), attracted the British capital. The establishment of first jute mill at Rishra in 1855 ushered in the era of modern industrial clustering in this region. The major concentration of jute industry is at Haora and Bhatapara. The partition of the country in 1947 adversely affected this industrial region. Cotton textile industry also grew along with jute industry, paper, engineering, textile machinery, electrical, chemical, pharmaceuticals, fertiliser and petrochemical industries have also developed within this region. Factory of the Hindustan Motors Limited at Konnagar and diesel engine factory at Chittaranjan are landmarks of this region.
Location of petroleum refinery at Haldia has facilitated the development of a variety of industries.

Important industrial centres of this region: Kolkata, Haora, Haldia, Serampur, Rishra, Shibpur, Naihati, Kakinara, Shamnagar, Titagarh, Sodepur, Birlanagar, Bansberia, Belgurriah, Triveni, Hugli, Belur, etc.
