Question 1.
Explain the significance of social infrastructure.
The significance of social infrastructure lies in the following:
(i) It helps in the healthy and robust growth of the young generation so that they become an efficient manpower tomorrow.
(ii) Social infrastructure helps in the growth of literacy, which in turn helps in the growth of the society.
(iii) Social infrastructure helps in the skill formation, which is an important parameter in the context of economic growth.
(iv) It helps in improving and providing a quality life to the people.
(v) Social infrastructure helps in the formation of human capital, which complements the physical capital to form an efficient system of growth and development

Question 2.
Why is it important to have strong infrastructure?
Infrastructure is the support system of the economy. All the sectors of the economy – agriculture industry, trade and commerce – greatly depend on the social and economic infrastructure for rapid: and vast economic development. It is a network of public services, physical and social facilities that increases the efficiency of factors of production and improves the quality of people’s life. Thus, infrastructure plays a vital role in the economic development of a country.

Question 3.
Compare and contrast India with China and Pakistan on the basis of infrastructural development.
The table below compares India’s position with its neighbouring countries on the basis of infrastructural development:

Country China India Pakistan
Investment in Infrastructure as a percentage of GDP – 2014 46 34 15
Access to Improved Water Source (%) – 2015 96 94 91
Access to Improved Sanitation (%) – 2015 77 40 64
Users of Mobile Phones per hundred person – 2015 93 79 70
Power Generation (billion kwh) – 2016 6015 1423 105

Source: World Development Indicators, 2017, data pertaining to 2014

In case of investment in infrastructure, as a percentage of GDP, China is far ahead of India and Pakistan. While China invests 46 per cent of its GDP in infrastructure, India and Pakistan invest only 34 and 15 per cent of their GDP respectively.

Access to drinking water is more or less the same for all the three nations, Power production is much better in China as compared to Pakistan and India. Modernisation process is faster in China compared to India and Pakistan. There 93 persons out of one hundred use mobile phones in China, In India 79 and in Pakistan only 70 out of one hundred persons were mobile users.

Thus, when we compare the development experience in terms of infrastructural development of these countries, we found that China is much ahead of India and Pakistan.

Question 4.
How is the national income of a country related to the level of infrastructural development? Explain.
The composition of infrastructure requirements changes significantly with the increase in country’s national income. Basic infrastructure facilities such as irrigation, transport and power are more important for low-income countries.

However, as economies grow and they are able to satisfy their basic consumption demand, the share of agriculture in the economy shrinks and more service related infrastructure become important. Thus, the share of power and telecommunication infrastructure is greater in high-income countries.

Question 5.

Question 6.
Which sources of energy are encouraged by India’s energy policy? Why?
India’s energy policy encourages hydel and wind energy as India has great potential in the use of a renewable source of energy. The use of renewable energy sources can ensure additional supply of power. Moreover, these sources do not rely on fossil fuel and hence, avoid carbon emissions. Greater reliance on renewable energy resources offers enormous economic, social and environmental benefits.

Question 7.
What problems are faced by State Electricity Boards?
The following problems are faced by State Electricity Boards:
(i) SEBs suffer transmission and distribution fosses, thereby making the economics of power generation completely unbalanced.

(ii) The pattern of investments being made in power generation is inappropriate. It leads to sharp increase in the cost per unit of electricity.

Question 10.
Give an account of the contribution of community and non-profit organisations to health care in India.
Community participation functions with the idea that the people can be trained and involved in primary healthcare system. Trade unions have built health care services to give low-cost health care to their members as well as to the people from nearby villages.

For instance, Shahid Hospital was built in 1983 and is sustained by the workers of Chhattisgarh Mines Shramik Sangh in Durg, Madhya Pradesh. SEW A in Ahmedabad and ACCORD in Nilgiris are examples of some non-profit organisations that contribute to health care in India.

Infrastructure Important Extra Questions Long Answer Type

Question 1.
Why is it important to conserve energy?
It is important to conserve energy due to the following reasons:
(i) Resources are limited. India has only 1 percent of world’s energy resources but it accounts for 16 percent of world population.

(ii) Resources take long time for formation. Coal and petroleum are the most widely used sources of energy. They take thousands of years for formation.

(iii) Resources are non-renewable. Non-renewable resources are those which get exhausted with extraction and use. Non-renewable energy sources constitute 80 percent of the fuel use. If we continue to use such resources at present rate, these will be soon depleted.

(iv) Use of resources involves high cost. About 75 percent of our crude oil needs depend on imports, which cost about ₹ 1,50,000 crore a year. The cost is passed on to the consumers by means of higher prices of goods and services.

(v) Environment needs protection. Sources which rely on fossil fuel emit huge amounts of carbon dioxide in the atmosphere. Energy production accounts to large proportion of air pollution and more than 83 percent of greenhouse gas emissions. According to a wise saying – “The earth, water and the air are not a gift to us from our parents but a loan from our children. Hence, we need to make energy conservation a habit.”

Explain the three-tier system of health infrastructure and health care in India.
Answer :
The three-tier system of health infrastructure and health care in India is as below:
(i) Primary Health Care: It includes education related to existing health problems and methods to identify, prevent and control them. It also constitutes promotion of food supply and proper nutrition; adequate water supply and sanitation; maternal and child health care; etc. In order to provide primary health care, Primary Health Centres (PHC), Community Health Centres (CHC) and sub-centres have been set up in villages and small towns.

(ii) Secondary Health Care: When PHCs are unable to manage the condition of a patient, they are referred to secondary hospitals. Secondary health care institutions include hospitals which have better facilities for surgery’, X-ray and Electro Cardio Gram (ECG). They are mostly located in district headquarters and big towns.

(iii) Tertiary Health Care: Hospitals under the tertiary sector have advanced level equipment and medicines. They undertake all the complicated health problems, which could not be managed by primary or secondary hospitals. This sector also includes many premier institutes, which provide specialised health care not along with imparting quality medical education and conducting research

Infrastructure Important Extra Questions HOTS

Question 1.
Why is India’s dependence import of crude and petroleum products increasing rapidly?
Although India is sufficiently rich in fossil fuels reserves, its dependence on imported fossil fuels has increased to 38 percent in 2012. With rapid modernisation and urbanisation, the country’s reliance has shifted from traditional biomass and waste to other energy sources, including fossil fuels.

Since coal and petroleum production are unable to keep pace with demand, India meets more of its coal and petroleum needs with imports. Net coal import dependency has increased from almost zero in 1990s to about 23 percent in 2012. Similarly, net oil import dependency has increased from 43 percent in 1990 to an around 71 percent in 2012.
