manufacturing industries.
Explain.
Answer:
The economic strength of a country lies in the development of manufacturing
industries. It is the backbone of development in general and economic
development in particular due to the following reasons:
- Manufacturing industries help in modernising
agriculture.
- It reduces the heavy dependence of people on
agricultural sector. At present more than half of the workers in the country are
still working in the primary sector, mainly in agricultural activities. The
workers in this sector are under employed.
- It provides jobs in secondary and tertiary sectors.
- Industrial development or manufacturing industries are
necessary for the removal of unemployment and poverty in a country like India.
This was the main philosophy behind public sector ventures in India.
- It brings down regional disparities by establishing
industries in tribal and backward areas.
- Export of manufactured goods expands trade and commerce
and brings in much needed foreign exchange.
- The industries make a country rich and prosperous
because raw materials are transformed into a wide variety of finished goods of
higher value which increases the income.
Question 97.
“Agriculture and industry are complementary to each other.” Explain with
examples.
Or
How do industries give boost to the agriculture sector?
Answer:
It is true that agriculture and industry move hand in hand.
- There are agro-based industries such as cotton, woollen,
jute, edible oil that get their raw materials from agriculture.
- In return, these industries sell their products such as
irrigation pumps, fertilisers, insecticides, PVC pipes and many other things to
the farmers.
- Thus agro-industries has given boost to agriculture by
raising its productivity and has made the production processes very efficient as
well.
Question 98.
What is the contribution of industry to national economy in India? Compare it
with the East Asian Countries. What is the desired growth and present position
of industry in GDP?

- The contribution of industry to national economy has
not been satisfactory for the last two decades. It has stagnated at 17 per cent
of GDP — out of a total of 27 per cent for the industry which includes 10 per
cent for mining, quarrying, electricity and gas.
- In comparison to India’s 17 per cent share in the GDP,
the East Asian Countries have contributed 25 to 35 per cent to their GDP.
- The trend of growth rate in manufacturing over the last
decade has been around 7 per cent per annum.
- The desired growth over the next decade is 12 percent.
- At present growth rate is about 9 to 10 per cent and it
is expected that we can achieve the growth rate of 12 per cent by some efforts
like setting up of the National Manufacturing Competitiveness Council (NMCC).
Question 99.
Why are industries located in or near the cities?
Or
Why do the industrialisation and urbanisation go hand in hand? Explain.
Answer:
Industrialisation and urbanisation go hand in hand because sometimes
industries are set up in or near the cities. The reasons for this are as
mentioned below:
- Industries need different types of services such as
labour, banking, transport, insurance and financial consultants. Such services
are available in cities.
- In cities the manufactured products are sold. They
become markets for these products and people are able to buy them according to
their requirements.
Availability of products attracts people from other parts to settle there. Thus, industrialisation leads to urbanisation. - Sometimes many industries are set up together to make
use of the advantage offered by the urban centers known as agglomeration
economies. Gradually a large industrial agglomeration takes place. Thus, it is
correct to state that the industries are located in or near the cities.
Question 100.
Where the most manufacturing units were located in the pre-independence period?
What were the results?

- In the pre-independence period, the manufacturing units
were located in places keeping in view the overseas trade. These places were
Mumbai, Kolkata and Chennai.
- Result :
- The result of locating the manufacturing industries at
Mumbai, Kolkata and Chennai and other places was the emergence of certain
pockets of industrially developed urban centers surrounded by a huge
agricultural rural hinterland.
- First cotton textile mill was set up at Mumbai in 1854.
- First jute mill was established at Rishra near Kolkata
in 1859.
- The result of locating the manufacturing industries at
Mumbai, Kolkata and Chennai and other places was the emergence of certain
pockets of industrially developed urban centers surrounded by a huge
agricultural rural hinterland.

:
Figure showing value addition in the textile industry:
From above it is clear that value at each step is added in the textile
industry and one has to go step by step.
Question 107.
Describe the condition of cotton textile industry in India before and after
independence.
Answer:
(1) Before independence :
- In ancient India and even during the British rule our
textiles were produced with hand spinning and handloom weaving techniques.
- India remained the world’s main producer of cotton
textiles.
- Indian textiles were of top quality and other countries
could not compete with it.
- There was great demand for Indian textiles and India had
a substantial export trade to Britain as well.
(2) During British period after 18th century textile industry suffered a
setback due to coming of Manchester goods in India. The Indian weavers could not
compete due to various reasons.
(3) At present the condition of cotton textile industry in India is as
mentioned below:
- There are 1600 cotton and human made fibre textile mills
in the country.
- About 80 per cent are in the private sector and the rest
in public and cooperative sectors.
- There are thousands of small factories with four to ten
looms.
- In the early years, cotton textile industry was
concentrated in the cotton growing belt of Maharashtra and Gujarat due to
availability of raw cotton, market, transport, labour and port facilities. But
now spinning is centralised in Maharashtra, Gujarat and Tamil Nadu but weaving
is highly decentralised to provide scope for incorporating traditional skills
and designs of weaving in cotton, silk, zari and embroidery.
- Cotton textiles industry is closely related to
agriculture. It provides a living to farmers, cotton boll pluckers and workers
engaged in ginning, spinning, weaving, dyeing, designing, packaging, tailoring
and sewing.
- It supports many other industries, such as, chemicals
and dyes, mill stores, packaging materials and engineering works by creating
various types of demands.
- India has world class production in spinning, but
weaving supplies low quality of fabric.
- The handspun khadi provides large scale employment to
weavers in their homes as a cottage industry.
- India exports yam to Japan and cotton goods to USA, UK,
Russia, France, East European countries, Nepal, Singapore, Sri Lanka and African
countries.
Question 108.
Describe the production of fabric in India by various sectors. Why is it
important for us to keep the mill sector loomage lower than the power loom and
handloom?
Answer:
(1) The production of fabric in India by various sectors is as mentioned
below :
Sector |
Share of production |
Loomage |
Mills
Powerloom
Handloom |
G.OCUper cent
54.17 per cent
23.00 per cent |
1.33 lakh
14 lakh
NA |
From above figure it is clear that 90 percent of the weaving, cutting and
processing is in decentralised sector.
(2) It is important for us to keep the mill/sector loomage lower than
power loom and handloom due to facts as mentioned below:
- In our country many artisans and weavers work
independently along with the familly on handloom and powerlooms.
- Most of these people working on handlooms and power
looms are poor. It is the only source of income for them.
- If the mill production is increased to meet the demands
of the people then these weavers and artisans will suffer as their sales will be
affected.
- Increase in mill production will lead largely to rural
unemployment and decline in standard of living.
Thus in order to provide more employment opportunities and regular income to these weavers, the loomage or the production of the mills must be kept lower than power loom and handloom.
Question 109.
Why is it important for us to improve our weaving sector instead of exporting
yam in large quantities?
Answer:
We need to make improvement in the weaving sector for the reasons as
mentioned below :
- Weaving machinery is old and needs to be upgraded to
give more output.
- Power supply to powerlooms is erratic and power needs to
be available on continuous basis.
- Weavers can directly supply cloth to garment
manufacturers instead of garment makers importing the fabric.
- This will also increase employment and incomes of the
weavers.
- Increasing the weaving capacity will increase the GDP
of country and create opportunity for development of ancillary industries like
dyeing, processing and printing of woven fabrics, production of stitched
garments.
- This could also mean reduction in imports of fabrics
and readymade garments thus saving foreign exchange reserves and using it for
other important products.
Question 110.
Explain why many of our spinners export cotton yam while apparel/garment
manufacturers have to import fabric.
Answer:
India’s share in the world trade of cotton yarn accounts for one-fourth of the
total trade. However, our trade in garments is only 4 per cent of the world’s
total but in spite of these facts many of our spinners export cotton yarn while
apparel/garment manufacturers have to import fabric. The reasons for this state
of affairs are as mentioned below:
- The weaving, knitting and processing units cannot use
much of the high quality yam that we produce.
- There are some large and modern factories but most of
the production is done in fragmented small units. These units cater to the needs
of loqal market. This mismatch is a major drawback for the industry.
- Production of good quality long staple cotton has
increased but India still imports due to the following reasons :
- Erratic power supply.
- Old machinery that needs upgradation.
- Low output of labour.
- Stiff competition with the synthetic fiber industry.
- Erratic power supply.
Question 111.
Describe the factors responsible for the location of most of the jute mills
along the banks of the Hugli River in West Bengal.

been on the increase? Which are the main markets for jute products?
Answer:
(1) The challenges faced by the jute industry are as mentioned below :
- Stiff competition in the international market from
synthetic substitutes.
- Competition with other countries like Bangladesh,
Brazil, Philippines, Egypt and Thailand.
(2) However inspite of the challenges, there is increase in the
internal demand due to factors as mentioned below:
- The government has made mandatory use of jute packaging.
- The growing global concern for environment friendly
biodegradable materials has also increased the use of jute products.
- In 2005 National Jute Policy was formulated with the
objective of increasing productivity, improving quality, ensuring good prices to
the jute farmers and enhancing the yield per hectare.
- The growing global concern for environment friendly
biodegradable materials has also helped in use of more jute products.
(3) The main markets are USA, Canada, Russia, United
Arab Republic, UK and Australia.
Question 113.
Give a brief description of sugar industry with special reference to its raw
material, its nature, location of sugar mills and place in the world.
Answer:
(1) Raw material : The raw material, i.e., sugarcane, is bulky and in
haulage, its sucrose content reduces. It is weight losing and perishable.
(2) Nature: This industry is seasonal in nature and, therefore, it is
ideally suited to the cooperative sector because it needs large manual labour in
various processes of cultivation and production of sugar and other products that
can be provided by the cooperatives.
(3)
- Location of sugar mills: There are
about 460 sugar mills which are located in Uttar Pradesh, Bihar, Maharashtra,
Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Punjab, Haryana and Madhya
Pradesh. Sixty per cent mills are in Uttar Pradesh and Bihar.
- In recent years there has been a tendency for the
sugar mills to shift and concentrate in the southern and western states due to
following reasons :
1. The
sugarcane produced in the southern and western states has a higher sucrose
content.
2. The
cooler climate also ensures a longer crushing season.
3. The
industry is ideally suited to the cooperative sector and this sector has been
more successful in these states.
4. Place
in the world: India stands second as a producer of sugar. It,
however, occupies the first place in the production of gurand
5. The
challenges before the sugar industry are its seasonal nature, old and
inefficient methods of production, transport delay in reaching sugarcane to
factories, need to maximise the use of baggase.
