Q1EXERCISES
Development of a country can generally be determined by
(i)
its per capita income
(ii)
its average literacy level
(iii)
health status of its people
(iv)
all the above
Solution
The correct answer is (iv) all the above.
As discussed in the chapter, development is a comprehensive concept that cannot be measured by a single indicator. While per capita income is an important measure of economic development, it is inadequate on its own. A true measure of development must also include social indicators such as the average literacy level and the health status of the population (e.g., Infant Mortality Rate and Life Expectancy). Therefore, a combination of all these factors provides a more complete picture of a country's development.
Q2EXERCISES
Which of the following neighbouring countries has better performance in terms of human development than India?
(i)
Bangladesh
(ii)
Sri Lanka
(iii)
Nepal
(iv)
Pakistan
Solution
The correct answer is (ii) Sri Lanka.
According to Table 1.6 in the chapter, which presents data from the Human Development Report 2023-24, Sri Lanka performs better than India in every respect. It has a higher Gross National Income (GNI) per capita, a greater Life Expectancy at birth, more Mean Years of Schooling, and a significantly better HDI Rank in the world (78 for Sri Lanka compared to 134 for India).
Q3EXERCISES
Assume there are four families in a country. The average per capita income of these families is Rs 5000. If the income of three families is Rs 4000, Rs 7000 and Rs 3000 respectively, what is the income of the fourth family?
(i)
Rs 7500
(ii)
Rs 3000
(iii)
Rs 2000
(iv)
Rs 6000
Solution
The correct answer is (iv) Rs 6000.
Calculation:
- Total number of families: 4
- Average per capita income: Rs 5000
- Total income of the four families: Average Income × Number of families = Rs 5000 × 4 = Rs 20,000
- Sum of the income of the first three families: Rs 4000 + Rs 7000 + Rs 3000 = Rs 14,000
- Income of the fourth family: Total Income – Sum of the income of three families = Rs 20,000 – Rs 14,000 = Rs 6,000
Q4EXERCISES
What is the main criterion used by the World Bank in classifying different countries? What are the limitations of this criterion, if any?
Solution
The main criterion used by the World Bank in its World Development Reports for classifying different countries is Per Capita Income, also known as average income.
Limitations of this criterion:
-
Hides Disparities: Per capita income is an average and does not show the actual distribution of income among the people. A country might have a high per capita income, but the wealth could be concentrated in the hands of a few rich individuals, while the majority of the population remains poor. The example in the chapter of Country A and Country B illustrates this, where both have the same average income, but Country A has an equitable distribution while Country B has extreme inequality.
-
Ignores Other Important Factors: Development is not just about income. Per capita income is a purely economic measure and ignores other crucial aspects of human well-being and quality of life. These include:
- Health: Indicators like Infant Mortality Rate and Life Expectancy.
- Education: Indicators like Literacy Rate and Net Attendance Ratio.
- Non-material factors: Aspects like security, freedom, equal treatment, and a pollution-free environment, which are essential for a good life but cannot be measured by income alone.
Q5EXERCISES
In what respects is the criterion used by the UNDP for measuring development different from the one used by the World Bank?
Solution
The criterion used by the United Nations Development Programme (UNDP) is significantly different from the one used by the World Bank because it takes a much broader and more holistic view of development.
-
World Bank's Criterion: The World Bank primarily uses a single economic indicator: Per Capita Income. It classifies countries as high-income, low-income, etc., based on this measure. This approach focuses solely on the economic aspect of development.
-
UNDP's Criterion: The UNDP, in its Human Development Report (HDR), uses a composite index called the Human Development Index (HDI). The HDI measures development based on three key dimensions of human well-being:
- A Long and Healthy Life: Measured by life expectancy at birth.
- Knowledge: Measured by educational levels (mean years of schooling and expected years of schooling).
- A Decent Standard of Living: Measured by Gross National Income (GNI) per capita.
In essence, while the World Bank's criterion is purely economic, the UNDP's criterion is multidimensional, combining income with crucial social indicators like health and education. This makes the UNDP's approach a more comprehensive measure of human development.
Q6EXERCISES
Why do we use averages? Are there any limitations to their use? Illustrate with your own examples related to development.
Solution
Why we use averages:
Averages are used to simplify complex data and make comparisons easier. For development, we use averages like per capita income to compare the economic status of different countries or states. Since countries have different populations, comparing their total income would not be meaningful. An average gives a single, representative value that can be easily compared.
Limitations of using averages:
The main limitation is that averages hide disparities and do not reflect the distribution of a quantity among people. They can mask extreme highs and lows, giving a misleading picture of the real situation.
Illustration related to development:
The chapter provides a clear example with two hypothetical countries, Country A and Country B. Both countries have an identical average monthly income of Rs 10,000.
- Country A: The income is distributed equitably, with citizens earning between Rs 9,500 and Rs 10,500. People are neither very rich nor extremely poor.
- Country B: The income distribution is highly unequal. Four citizens earn only Rs 500 each, while one citizen is extremely rich with an income of Rs 48,000.
Even though the average income is the same, Country A is socially and economically more developed and stable. The average income figure completely hides the extreme poverty and inequality in Country B. This shows that while averages are useful for comparison, they must be used with caution and supplemented with other information about distribution and equity.
Q7EXERCISES
Kerala, with lower per capita income has a better human development ranking than Haryana. Hence, per capita income is not a useful criterion at all and should not be used to compare states. Do you agree? Discuss.
Solution
I do not fully agree with the statement that per capita income is not a useful criterion at all and should not be used. While the case of Kerala and Haryana demonstrates the limitations of per capita income as the sole measure of development, it does not render it completely useless.
Points of Agreement:
The statement is correct in pointing out that per capita income alone is an inadequate measure. As shown in Tables 1.3 and 1.4, Haryana has a much higher per capita income than Kerala. However, Kerala performs significantly better on crucial human development indicators:
- Infant Mortality Rate: Kerala's is much lower (6 per 1000) compared to Haryana's (28 per 1000).
- Literacy Rate: Kerala's is higher (94%) than Haryana's (82%).
- Net Attendance Ratio: Kerala's is higher (94%) than Haryana's (73%). This is because Kerala has made better provisions for public health and educational facilities, which are accessible to all. This example clearly shows that high income does not automatically translate to a better quality of life.
Points of Disagreement:
However, to conclude that per capita income is 'not useful at all' is an overstatement. Income is still a very important component of development because it provides individuals with the means to purchase goods and services that they need to live well. A higher national income allows a government to spend more on public facilities like schools, hospitals, and infrastructure.
Conclusion:
Per capita income is a useful but insufficient criterion for comparing states. It should not be discarded, but rather used in conjunction with other important social indicators related to health, education, and equality. The comparison between Kerala and Haryana perfectly illustrates why development should be viewed as a mix of goals, including both income and other aspects of human well-being.
Q8EXERCISES
Find out the present sources of energy that are used by the people in India. What could be the other possibilities fifty years from now?
Solution
Present sources of energy in India:
The primary sources of energy currently used in India are predominantly non-renewable fossil fuels. These include:
- Coal: The largest source, used mainly for electricity generation and in industries.
- Petroleum (Crude Oil) and its products (Petrol, Diesel): Used primarily for transportation and in various industries.
- Natural Gas: Used for power generation, as fuel in industries, and for domestic cooking (LPG/PNG).
- Hydroelectricity: Energy generated from the force of flowing water in dams.
- Nuclear Energy: Generated from nuclear fission, contributing a small but significant portion of electricity.
Other possibilities fifty years from now:
Given the depletion of fossil fuels and the growing concern for environmental sustainability, India will need to shift towards renewable and cleaner energy sources. Fifty years from now, the energy landscape could be dominated by:
- Solar Energy: With India's abundant sunshine, solar power (both photovoltaic cells and solar thermal) is expected to be a major source of electricity for homes, industries, and agriculture.
- Wind Energy: Expansion of wind farms, especially in coastal areas and states with high wind potential, will contribute significantly to the power grid.
- Green Hydrogen: Produced using renewable energy, it can be used as a clean fuel for transportation and heavy industries.
- Biofuels and Biomass Energy: Energy derived from organic matter like agricultural waste can be used for rural energy needs and to produce fuels like ethanol.
- Geothermal Energy: Tapping into the heat from the Earth's core in specific regions.
- Tidal and Wave Energy: Harnessing the power of ocean tides and waves along India's long coastline.
This shift is crucial for ensuring the sustainability of development for future generations.
Q9EXERCISES
Why is the issue of sustainability important for development?
Solution
The issue of sustainability is important for development because it ensures that the process of development does not compromise the ability of future generations to meet their own needs. It links development in the present with the well-being of the future.
Here are the key reasons for its importance:
-
Resource Management: Current development models are heavily dependent on natural resources. Sustainability promotes the wise and efficient use of these resources.
- Renewable Resources: It warns against the overuse of renewable resources like groundwater, which can be depleted if used faster than they are replenished by nature.
- Non-Renewable Resources: It highlights the fact that non-renewable resources like crude oil and coal are finite and will get exhausted. Sustainable development encourages finding alternatives and using these resources judiciously.
-
Preservation for Future Generations: The core idea of sustainability is inter-generational equity. As the chapter quotes, "We have not inherited the world from our forefathers — we have borrowed it from our children." Unsustainable development benefits the present generation at the cost of the future, which is ethically and morally wrong.
-
Environmental Protection: Unsustainable development activities often lead to severe environmental degradation, such as air and water pollution, deforestation, and climate change. These consequences do not respect national boundaries and affect everyone, threatening the very basis of life and future progress.
In summary, sustainability ensures that development is long-lasting and balanced, meeting present needs without destroying the natural environment and resource base upon which all future development depends.
Q10EXERCISES
"The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person". How is this statement relevant to the disscusion of development? Discuss.
Solution
This statement, often attributed to Mahatma Gandhi, is highly relevant to the discussion of development, particularly the concept of sustainability and equity.
Relevance to Development:
-
Distinction between 'Need' and 'Greed': The statement makes a crucial distinction between human 'needs' and 'greed'.
- Need refers to the basic requirements for a dignified life, such as food, water, shelter, health, and education. A key goal of development is to ensure that these needs are met for all people.
- Greed refers to the limitless desire for more wealth, consumption, and resources, far beyond what is necessary. Modern models of development, especially in industrialized nations, often promote a culture of overconsumption that reflects this greed.
-
Critique of Unsustainable Development: The current path of development is often driven by 'greed', leading to the rapid and reckless exploitation of natural resources. This includes over-extraction of minerals, deforestation for commercial purposes, and overuse of water resources. This unsustainable consumption exhausts resources that are meant for everyone.
-
Emphasis on Equity and Distribution: The statement implies that the Earth's resources are sufficient if they are distributed equitably to meet everyone's basic needs. However, the 'greed' of a few powerful individuals, corporations, or countries leads to the hoarding and over-utilization of resources, depriving a large portion of the world's population of even their most basic necessities. This explains the paradox of poverty and hunger existing in a world of plenty.
-
Advocacy for Sustainable Development: The statement inherently calls for a model of development that is sustainable, just, and equitable. It suggests that development should focus on fulfilling the needs of all, rather than fueling the endless wants of a few. This requires a shift from a purely growth-oriented model to one that prioritizes human well-being, environmental preservation, and social justice for both present and future generations.
Q11EXERCISES
List a few examples of environmental degradation that you may have observed around you.
Solution
Here are a few examples of environmental degradation that can be commonly observed:
-
Water Pollution: The dumping of untreated sewage and industrial chemical waste into nearby rivers, lakes, or canals, making the water unfit for use and harming aquatic life.
-
Air Pollution: Visible smoke and fumes released from factory chimneys, vehicles, and the burning of garbage, which leads to smog and respiratory problems in urban areas.
-
Land and Soil Pollution: The improper disposal of plastic bags, bottles, and other non-biodegradable solid waste in open areas. The overuse of chemical fertilizers and pesticides in agriculture also degrades soil quality over time.
-
Deforestation: The cutting down of trees in and around cities and villages for the construction of roads, buildings, and factories, which leads to loss of green cover and biodiversity.
-
Groundwater Depletion: The increasing number of borewells and submersible pumps in residential areas, leading to a significant drop in the groundwater level, as mentioned in the chapter.

Q13EXERCISES
The following table shows the proportion of adults (aged 15-49 years) whose BMI is below normal (BMI < 18.5 kg/m²) in India. It is based on a survey of various states for the year 2019-21. Look at the table and answer the following questions.
State Male (%) Female (%) Kerala 8.5 10 Karnataka 17 21 Madhya Pradesh 28 28 All States 20 23
(i)
Compare the nutritional level of people in Kerala and Madhya Pradesh.
(ii)
Can you guess why around one-fifth of people in the country are undernourished even though it is argued that there is enough food in the country? Describe in your own words.
Solution
(i)
Comparison of nutritional levels in Kerala and Madhya Pradesh:
Based on the table, the nutritional level of people in Kerala is significantly better than that in Madhya Pradesh. In Kerala, only 8.5% of males and 10% of females are undernourished. In sharp contrast, Madhya Pradesh has a much higher proportion of undernourished adults, with 28% of both males and females having a BMI below normal. This indicates a severe problem of malnutrition in Madhya Pradesh compared to Kerala.
(ii)
Reasons for undernourishment despite sufficient food:
Even though India produces enough food to feed its population, around one-fifth of the people are undernourished. This paradox can be explained by the following reasons:
-
Ineffective Public Distribution System (PDS): The problem is not the availability of food but its accessibility and distribution. As discussed in the chapter, the health and nutritional status of people is better in states where the PDS functions well. In many parts of the country, the system is inefficient or corrupt, preventing food grains from reaching the poor and needy.
-
Poverty and Lack of Purchasing Power: A large section of the population is poor and does not have enough income to buy nutritious food, even if it is available in the market.
-
Lack of Awareness: People, especially in rural and remote areas, may lack awareness about the importance of a balanced and nutritious diet, leading to poor food choices.
-
Social and Gender Discrimination: In some households, women and girls are given less nutritious food than men and boys, leading to higher rates of malnutrition among females.
Therefore, the issue of undernourishment is more a problem of distribution, poverty, and lack of public facilities than a problem of food production.
