Class 11 Economics Chapter 8: Infrastructure (NCERT Indian Economic Development)

Key takeaways

Infrastructure is economic (energy, transport, communication) and social (education, health, housing).
India invested only about 5 per cent of GDP in infrastructure in the book’s comparison.
Coal gives 55 per cent of commercial energy; power faces losses and shortfalls.
Health care has three tiers, but rural areas have far fewer facilities.
More than 70 per cent of hospitals are private; the poor rely on public ones.

This is Chapter 8 of the Indian Economic Development chapter list for Class 11 Economics. It follows Chapter 7 and develops the health theme of Chapter 5.

8.1What Is Infrastructure and Why Does It Matter?

Infrastructure is the set of support services on which production and trade depend: roads, railways, ports, airports, power, telecommunications, schools, hospitals, sanitation and banking. Economic infrastructure covers energy, transport and communication; social infrastructure covers education, health and housing. It raises productivity and improves quality of life, so weak infrastructure holds development back.

States such as Punjab, Maharashtra, Gujarat, Kerala and Karnataka excel in different fields partly because they have the infrastructure that suits them: irrigation, ports, transport, social services or telecom links. Modern agriculture needs fast transport of seeds, fertiliser and produce, plus banking and insurance; industry needs power, transport and communication.

Infrastructure also affects health. Clean water and sanitation sharply cut waterborne disease, and good transport and communication improve access to care, while air pollution and accidents from transport add to illness.

Infrastructure and regional inequality

Places with good roads, power and irrigation attract firms and grow faster, while places without them fall behind. The textbook notes that states excel in different fields partly because their infrastructure suits them: irrigation in the farming states, ports and roads in industrial states, and social infrastructure in Kerala.

If infrastructure is concentrated in a few regions, income gaps widen. Spending on infrastructure in lagging areas is therefore also a way of promoting balanced development.

8.2The State of Infrastructure in India

Traditionally government alone built India’s infrastructure, but investment proved inadequate, so private and public-private partnership projects are now important. India invested only about 5 per cent of GDP in infrastructure in the book’s comparison, far below China and Indonesia. Rural households still lack electricity, piped water and sanitation, and rely on biofuels for cooking.

The 2001 Census found only 56 per cent of rural households with an electricity connection and 43 per cent still using kerosene. About 90 per cent of rural households used biofuels for cooking, only 24 per cent of rural households had tap water, and in 1996 access to improved sanitation in rural areas was just 6 per cent. Rural women walk long distances to fetch fuel and water. As income rises, the mix of infrastructure shifts from irrigation, transport and power to services such as telecommunications.

Terms in the news include Special Purpose Vehicles, Special Economic Zones, Build-Operate-Transfer and Public-Private Partnership, all routes for bringing private money into infrastructure. The book focuses on two kinds: energy and health.

How economic and social infrastructure support each other

Roads help children reach schools and patients reach clinics, and reliable power lets hospitals run equipment and lets students study after dark. In the same way, schools produce the engineers, technicians and managers who build and run the economic infrastructure. A weakness in one kind of infrastructure therefore spills over into the other.

Because infrastructure serves many users and takes years to build, it is costly and hard for private firms to provide alone. Governments plan it, and private partners are brought in under arrangements such as build-operate-transfer. The aim is to ensure that growing areas get power, roads and water in time, since shortages raise costs for every business.

8.3Energy

Energy is needed for industry, farming, transport and homes. Commercial sources, coal, petroleum and electricity, are bought and sold and are mostly exhaustible; non-commercial sources, firewood, dung and crop waste, are renewable. Demand for power grows faster than GDP, and India’s power sector faces shortfalls, distribution losses and import dependence on oil.

Figure 8.1: India’s commercial energyCoal dominates. More than 60 per cent of households still depended on traditional fuels for cooking and heating, according to the book.

Sources of energy
Type	Examples	Features
Commercial (conventional)	Coal, oil, natural gas, electricity	Bought and sold; generally exhaustible except hydropower
Non-commercial (conventional)	Firewood, agricultural waste, dried dung	Found in nature; renewable
Non-conventional	Solar, wind, tidal power	Almost unlimited potential in a tropical country; need cost-effective technology

Power

Electricity is a secondary form of energy, produced from primary sources. In 2003-04 thermal sources made up almost 70 per cent of generating capacity; nuclear energy gave about 2.4 per cent of primary energy against a global average of 13 per cent. To sustain 8 per cent GDP growth, power supply must grow around 12 per cent a year.

Challenges in the power sector

Installed capacity is insufficient for 7 per cent annual growth and is under-used because plants are poorly run.
State Electricity Boards lose over ₹500 billion because of transmission and distribution losses, wrongly priced power, and theft.
Private and foreign investors have yet to play a major role.
High tariffs and power cuts cause public unrest.
Thermal plants face shortages of coal and other inputs.

Saving energy helps too: replacing a million 100-watt bulbs with 20-watt CFLs would save 80 megawatts, worth about ₹400 crore at ₹5 crore a megawatt of generating cost. India was the world’s fifth-largest wind power producer in the book, with over 95 per cent of the investment private.

Why saving energy matters

Saving a unit of electricity is cheaper than generating a new one. The textbook example of replacing ordinary bulbs by compact fluorescent lamps shows that a million 100-watt bulbs swapped for 20-watt lamps would save 80 megawatts, worth about ₹400 crore of generating capacity at ₹5 crore a megawatt. Households, factories and farms can all reduce waste through efficient appliances and pumps.

Efficiency reduces imports of fuel, cuts pollution and eases pressure on the power grid. It is, therefore, part of energy policy along with new generation, reduction of transmission losses and a shift towards renewable sources.

8.4Health Infrastructure

Health is not just the absence of disease but the ability to realise one’s potential. Health infrastructure includes hospitals, doctors, nurses, beds, equipment and a pharmaceutical industry, and must be accessible to all. India has a three-tier system of primary, secondary and tertiary care, but rural areas and the poor remain underserved.

Figure 8.2: Public health infrastructure grewHospitals multiplied nearly 6 times between 1951 and 2000, and primary health centres more than 31 times.

Between 1951 and 2000 hospitals and dispensaries rose from 9,300 to 43,300 and beds from 1.2 to 7.2 million. Allopathic doctors increased from 0.62 to 5 lakh and nursing staff from 0.18 to 8.7 lakh. Smallpox and guinea worm were eradicated and polio and leprosy nearly so.

The three-tier health system
Tier	Institutions	Role
Primary	Sub-centres, Primary Health Centres, Community Health Centres; the Auxiliary Nursing Midwife is first contact in villages	Health education, nutrition, water and sanitation, mother and child care, immunisation, essential drugs
Secondary	District and town hospitals	Surgery, X-ray, ECG and referral care
Tertiary	Premier institutions such as AIIMS and PGI	Advanced treatment, medical education and research

Private sector and Indian systems of medicine

More than 70 per cent of hospitals are privately run, holding nearly two-fifths of beds and serving 80 per cent of outpatients and 46 per cent of inpatients. The sector has grown with little regulation, and super-specialty hospitals now serve richer patients and medical tourists. AYUSH stands for Ayurveda, Yoga, Unani, Siddha, Naturopathy and Homeopathy; it has thousands of hospitals and dispensaries and over six lakh registered practitioners, but little has been done to standardise education or research.

Health indicators and gaps

Health spending was about 5 per cent of GDP, low compared with other countries.
India has about 17 per cent of the world’s people but about 20 per cent of the global burden of disease, more than half from communicable diseases like diarrhoea, malaria and tuberculosis.
Less than 20 per cent of people used public health facilities; only 38 per cent of PHCs had the required doctors and 30 per cent enough medicines.
Rural areas have 70 per cent of the population but only a fifth of hospitals and about 11 per cent of beds: 0.36 hospitals per lakh people in rural areas against 3.6 in urban areas.
Medical costs push about 2.2 per cent of the population below the poverty line each year.

Why preventive care is cost-effective

Preventive health measures, such as immunisation, clean water, sanitation and health education, cost much less than treating disease after it occurs. The eradication of smallpox and the near-eradication of polio show what organised public health can achieve. Poor sanitation, in contrast, spreads diarrhoea and other water-borne diseases that kill children every year.

For the poor, a single serious illness can mean heavy borrowing or sale of assets. A strong primary tier of health care, close to people, is therefore one of the most direct ways of protecting both health and household income.

Worked Examples

Example 1: Net electricity availability

Given: A power station generates 1,000 million units. Auxiliary consumption and transmission and distribution losses total 22 per cent (illustrative).
Formula: Net availability = generation × (1 − loss rate)
Steps: 1,000 × (1 − 0.22) = 780.
Answer: Only 780 million units reach consumers; the rest is lost.

Example 2: Savings from CFLs

Given: One million 100-watt bulbs are replaced by 20-watt CFLs. Generating capacity costs ₹5 crore per megawatt.
Formula: Saving = number × watts saved; value = MW × cost per MW
Steps: Saving per bulb = 80 W. 10⁶ × 80 W = 80 MW. 80 × 5 = 400.
Answer: 80 MW is saved, equal to ₹400 crore of avoided capacity.

Example 3: Growth of public hospitals

Given: Hospitals numbered 2,694 in 1951 and 15,888 in 2000; PHCs 725 and 22,842.
Formula: Multiple = later ÷ earlier
Steps: 15,888 ÷ 2,694 = 5.9. 22,842 ÷ 725 = 31.5.
Answer: Hospitals grew about 5.9 times and PHCs about 31.5 times.

Example 4: Rural–urban gap in hospitals

Given: There are 0.36 hospitals per lakh people in rural areas and 3.6 in urban areas. A rural block has 50 lakh people.
Formula: Hospitals = rate × population in lakh
Steps: Rural rate: 0.36 × 50 = 18. At the urban rate: 3.6 × 50 = 180. Ratio 3.6 ÷ 0.36 = 10.
Answer: The block has 18 hospitals against 180 at the urban rate: rural areas have one-tenth the coverage.

Common Mistakes

Calling infrastructure only roads and power. Schools, hospitals, sanitation and banks are infrastructure too.
Saying all energy sources are exhaustible. Firewood, dung and hydro are renewable.
Judging health only by hospital numbers. Access, staffing and medicines matter equally.
Treating private health care as a substitute for government. The poor depend on public hospitals.

10 Important Questions for Class 11 Board and School Examinations

Questions are written in original words. Marks are shown beside each question.

Q1Which of the following is a non-commercial source of energy? (a) coal (b) petroleum (c) firewood (d) electricity 1 mark · MCQ

The correct option is (c) firewood.

Q2Which of these is social infrastructure? (a) roads (b) power (c) hospitals (d) pipelines 1 mark · MCQ

The correct option is (c) hospitals.

Q3Assertion (A): Health infrastructure alone cannot ensure a healthy population. Reason (R): It must also be accessible and affordable to all. Which is correct? 1 mark · Assertion-reason

Both A and R are true, and R explains A.

Q4What is infrastructure? Give two examples each of economic and social infrastructure. 3 marks

Infrastructure is the set of support services on which production, trade and daily life depend.

Economic infrastructure: energy, transport and communication, for example power stations and railways.
Social infrastructure: education, health and housing, for example schools and hospitals.

It raises the productivity of factors of production and improves people’s quality of life, which is why weak infrastructure holds back development. Some services support production directly, while others support it indirectly by building the social sector.

Q5Distinguish between commercial and non-commercial energy. 3 marks

Commercial energy is bought and sold and mostly exhaustible, while non-commercial energy is gathered from nature and renewable.

Commercial sources: coal, petroleum, natural gas and electricity; hydropower is the renewable exception.
Non-commercial sources: firewood, agricultural waste and dried dung.
Commercial energy was about 65 per cent of India’s energy use, and non-commercial over 30 per cent, in the book’s data.

Rural households still depend heavily on non-commercial fuels.

Q6Explain the challenges facing India’s power sector. 4 marks

India’s power sector faces shortfalls in capacity, heavy losses and weak private participation.

Installed capacity is insufficient for 7 per cent annual growth, and existing plants are under-used because they are poorly run.
State Electricity Boards lose over ₹500 billion through transmission and distribution losses, wrong pricing and theft.
Private and foreign investors have not played a major role.
High tariffs and long power cuts cause public unrest.
Thermal plants face shortages of coal and other inputs.

Demand for power grows faster than GDP.

Q7Describe the three-tier health care system. 4 marks

India has a three-tier health system of primary, secondary and tertiary care.

Primary: sub-centres, Primary Health Centres and Community Health Centres give basic care, immunisation, nutrition and mother and child services; the Auxiliary Nursing Midwife is the first contact in villages.
Secondary: district and town hospitals with surgery, X-ray and ECG facilities, taking referrals from the primary tier.
Tertiary: advanced hospitals and premier institutes such as AIIMS, PGI Chandigarh and JIPMER.

Patients are referred upwards when a lower tier cannot manage the case. Private and voluntary hospitals work alongside this public system.

Q8Explain the role of the private sector in health care and its limitations. 6 marks

The private sector provides most hospitals and outpatient care, but it is poorly regulated and serves mainly those who can pay.

More than 70 per cent of hospitals are private, with nearly two-fifths of beds and 80 per cent of outpatient care.
Private firms dominate medical education, diagnostics, pharmaceuticals and hospital construction.
Since the 1990s super-specialty hospitals have been set up for the rich and for medical tourists.
The sector grew with little regulation, and some practitioners are not registered doctors.
Over 80 per cent of the 13 lakh medical enterprises are run by one person.

The poor depend on government hospitals, so the state’s role remains vital.

Public and private roles are therefore complementary: private providers add capacity, while government must regulate quality and provide care where profit is low.

Q9Discuss the urban–rural and poor–rich divide in health infrastructure. 6 marks

Rural areas and poorer groups have far less access to health infrastructure than urban areas and richer groups.

70 per cent of people live in rural areas, yet only about one-fifth of hospitals and about 11 per cent of beds are there.
Hospitals per lakh people: 0.36 in rural areas against 3.6 in urban areas.
Many PHCs lack staff and medicines; only 38 per cent had the required doctors and 30 per cent enough medicines.
Less than 20 per cent of people use public health facilities.
Medical costs push about 2.2 per cent of the population below the poverty line each year.

Health status therefore differs sharply between rural and urban, and rich and poor, groups.

Improving primary health care in villages is the most direct way to narrow these gaps.

Q10A power station generates 2,000 million units and 25 per cent is lost in auxiliary use and transmission. Find the net availability. How many units would be saved if losses fell to 15 per cent? 4 marks · Numerical

Net availability is 1,500 million units; cutting losses to 15 per cent saves 200 million units.

Steps: 2,000 × 0.75 = 1,500. At 15 per cent: 2,000 × 0.85 = 1,700. Gain = 200.
