Development — NCERT Solutions

From Table 1.5, the literacy rate for rural population is 76% for males and 54% for females. The blank asking for adults currently not in school refers to children who are now not attending school.

The high level of illiteracy among the children's age group is most disturbing. The chapter refers to children aged 10–14 years.

Correct Option: (iv) all the above

Justification: Development of a country cannot be measured by a single indicator alone. Per capita income tells us about the average economic well-being, literacy level reflects educational attainment, and health status indicates the physical well-being of citizens. Together, these indicators give a more comprehensive and accurate picture of a country's development. Hence, all the above criteria are used.

Correct Option: (ii) Sri Lanka

Justification: Among India's neighbouring countries, Sri Lanka has a significantly higher Human Development Index (HDI) rank than India. Sri Lanka performs better on indicators such as life expectancy, literacy rate, and per capita income compared to India. Bangladesh, Nepal, and Pakistan all rank lower than India on the HDI.

Correct Option: (iv) Rs 6000

Given:

• Number of families = 4
• Average per capita income = Rs 5000
• Income of three families = Rs 4000, Rs 7000, Rs 3000

Formula:
$$\text{Average} = \frac{\text{Sum of all incomes}}{\text{Number of families}}$$

Step 1: Find the total income of all four families.
$$\text{Total income} = \text{Average} \times \text{Number of families} = 5000 \times 4 = \text{Rs } 20000$$

Step 2: Find the sum of the three known incomes.
$$4000 + 7000 + 3000 = \text{Rs } 14000$$

Step 3: Find the income of the fourth family.
$$\text{Income of fourth family} = 20000 - 14000 = \text{Rs } 6000$$

Answer: The income of the fourth family is Rs 6000.

Main Criterion used by the World Bank:

The World Bank classifies countries on the basis of per capita income (i.e., the total income of a country divided by its total population). Countries with a per capita income of US$13,205 per annum or above (as per recent data) are called **high-income or rich countries**, and those with a per capita income of US$ 1,085 or less are called low-income countries. India falls in the category of lower-middle-income countries.

Limitations of Per Capita Income as a Criterion:

1. Ignores distribution of income: Per capita income is an average figure. It does not tell us how income is distributed among the people. A country may have a high per capita income but extreme inequality, where a few are very rich and the majority are very poor.

Example: If in a group of 5 people, one person earns Rs 1,00,000 and the other four earn Rs 5,000 each, the average income appears high but most people are actually poor.

2. Does not reflect quality of life: Per capita income does not capture important aspects of human well-being such as health, education, life expectancy, access to clean water, and social security.

3. Non-monetary factors ignored: Factors like freedom, security, equal treatment, and environmental quality, which contribute to a good life, are not reflected in per capita income.

4. Misleading comparisons: Two countries with the same per capita income may have very different standards of living if one has better public services (health, education) than the other.

Conclusion: While per capita income is a useful starting point, it is an incomplete measure of development and must be supplemented with other indicators.

Criterion used by the World Bank:
The World Bank uses per capita income (average income per person per year) as the sole criterion to classify and compare countries in terms of development.

Criterion used by the UNDP:
The United Nations Development Programme (UNDP) uses the Human Development Index (HDI) to measure and compare development. The HDI is a composite index based on three dimensions:

Key Differences:

Conclusion: The UNDP's approach is more comprehensive because it recognises that development is not just about income but also about people's health, education, and overall quality of life. It treats people as the real wealth of a nation.

Why do we use Averages?

Averages are used because they provide a single representative value for a large set of data, making it easier to compare different groups, regions, or countries.

• When comparing the income levels of different countries with millions of people, it is not possible to compare individual incomes. The per capita income (average income) allows a quick and simple comparison.
• Averages help in summarising complex data and identifying general trends.

Limitations of Averages:

1. Hides inequality/disparity: The average does not show how the data is distributed. It can be misleading if there is a wide gap between the highest and lowest values.

Example related to development: Suppose in a village of 5 families, the monthly incomes are Rs 500, Rs 500, Rs 500, Rs 500, and Rs 48,000. The average income = $\frac{500+500+500+500+48000}{5} = \frac{50000}{5} =$ Rs 10,000. This average suggests the village is relatively prosperous, but in reality, four out of five families are very poor.

2. Does not reflect the actual situation of the majority: A country may have a high per capita income due to a small number of very wealthy people, while the majority of the population may be living in poverty.

Example: Two states A and B both have an average per capita income of Rs 20,000. In State A, most people earn between Rs 18,000–22,000 (fairly equal distribution). In State B, a few people earn Rs 1,00,000 and the rest earn only Rs 5,000. The average is the same, but the standard of living is very different.

3. Ignores non-income factors: Averages of income do not capture health, education, or social equality.

Conclusion: Averages are useful tools for comparison but must be used carefully. They should be supplemented with information about distribution and other qualitative indicators to get a true picture of development.

Answer: No, I do not fully agree with this statement.

Explanation:

It is true that Kerala has a lower per capita income than Haryana, yet Kerala ranks much higher on human development indicators such as:

• Life expectancy (Kerala ≈ 75 years vs Haryana ≈ 68 years)
• Literacy rate (Kerala ≈ 94% vs Haryana ≈ 76%)
• Infant mortality rate (Kerala has one of the lowest in India)

This clearly shows that per capita income alone is not sufficient to measure development or the quality of life of people.

However, this does not mean per capita income is useless:

1. Per capita income is still an important indicator of the economic resources available to a country or state. Higher income generally means more resources for public spending on health and education.

2. It is a simple and easily measurable criterion that allows quick comparisons.

3. It serves as a starting point for development analysis.

The real lesson from Kerala vs Haryana:

The comparison shows that how income is used matters more than the level of income. Kerala has invested heavily in public health and education, leading to better human development outcomes despite lower per capita income. Haryana, despite higher income, has not translated it equally into human well-being.

Conclusion: Per capita income is a useful but incomplete criterion. It should not be discarded but must be used alongside other indicators like health, education, and life expectancy (as in the HDI) to get a complete picture of development.

Present Sources of Energy used in India:

• In rural areas, firewood, cow dung cakes, and agricultural waste are still widely used for cooking.
• In urban areas, LPG (liquefied petroleum gas), electricity (from coal/hydro/nuclear), and CNG (compressed natural gas) are commonly used.
• Coal is the dominant source for electricity generation in India.

Possible Energy Sources Fifty Years from Now:

Given that fossil fuels (coal, petroleum, natural gas) are non-renewable and are being rapidly depleted, India will need to shift to alternative and sustainable sources of energy. Possibilities include:

1. Solar energy — India receives abundant sunlight; solar panels and solar farms can meet large energy needs.
2. Wind energy — Wind farms, especially in coastal and high-altitude areas.
3. Hydrogen fuel — Green hydrogen produced using renewable energy is a promising future fuel.
4. Tidal and wave energy — Harnessing energy from ocean tides and waves.
5. Advanced nuclear energy — Thorium-based nuclear reactors (India has large thorium reserves).
6. Geothermal energy — Energy from the Earth's internal heat.
7. Biofuels — Ethanol and biodiesel from agricultural waste.

Conclusion: The future of energy in India lies in renewable and sustainable sources. Transitioning away from fossil fuels is essential for both environmental sustainability and long-term energy security.

Meaning of Sustainability in Development:

Sustainability means meeting the needs of the present generation without compromising the ability of future generations to meet their own needs. Sustainable development ensures that economic growth does not come at the cost of environmental destruction.

Why Sustainability is Important for Development:

1. Non-renewable resources are finite: Resources like coal, petroleum, and natural gas took millions of years to form. Once exhausted, they cannot be replenished. If we use them recklessly today, future generations will have no access to them.

Example: At the current rate of consumption, known oil reserves may last only a few more decades.

2. Environmental degradation threatens future growth: Deforestation, soil erosion, water pollution, and air pollution reduce the productive capacity of the Earth. This directly harms agriculture, health, and economic activity.

3. Groundwater depletion: Over-extraction of groundwater for irrigation and industry is depleting aquifers. If groundwater is exhausted, future generations will face severe water scarcity.

4. Climate change: Burning fossil fuels releases greenhouse gases, causing global warming and climate change. This threatens food security, coastal areas, and biodiversity worldwide.

5. Intergenerational equity: Development should be fair not just to people living today but also to those who will live in the future. Leaving a degraded environment is a form of injustice to future generations.

6. Consequences cross boundaries: Environmental degradation does not respect national or state borders. Problems like climate change, ozone depletion, and loss of biodiversity are global issues requiring collective responsibility.

Conclusion: Development that ignores sustainability is self-defeating in the long run. True development must balance economic growth with the conservation of natural resources and the environment, ensuring a good quality of life for both present and future generations.

Explanation of the Statement:

This statement, attributed to Mahatma Gandhi, draws a distinction between need and greed. It suggests that:

• The Earth's natural resources are sufficient to provide a decent standard of living to every person on the planet.
• However, if individuals or nations consume resources far beyond their basic needs — driven by greed and excessive consumption — the Earth's resources will fall short even for one such person.

Relevance to Development:

1. Unsustainable consumption patterns: Developed and wealthy nations consume a disproportionately large share of the world's resources. For example, the per capita energy consumption of a person in the USA is many times higher than that of a person in India or Africa. If every person on Earth consumed at that level, the planet's resources would be exhausted very quickly.

2. Inequality in resource use: While millions of people in developing countries lack access to clean water, food, and electricity, wealthy individuals and corporations waste enormous amounts of resources. This inequality is both unjust and unsustainable.

3. Environmental degradation due to greed: Over-mining, deforestation, over-fishing, and industrial pollution are largely driven by the desire for profit beyond necessity. This degrades the environment and reduces resources available for future generations.

4. Need-based vs. greed-based development: The statement calls for a model of development that is need-based — ensuring that every person's basic needs (food, water, shelter, health, education) are met — rather than greed-based, which leads to overconsumption by a few at the expense of many.

5. Sustainable development: If all countries pursue development by exploiting resources without restraint, the Earth's ecological balance will be destroyed. Sustainable development requires that we use resources wisely and equitably.

Conclusion: This statement is a powerful reminder that the goal of development should be to fulfil the basic needs of all people, not to enable unlimited accumulation by a few. Equitable and sustainable use of the Earth's resources is the foundation of true development.

Examples of Environmental Degradation:

The following are common examples of environmental degradation that can be observed in everyday life:

1. Air pollution: Smoke and harmful gases emitted by vehicles, factories, and the burning of crop stubble (as seen in Delhi-NCR during winter) cause severe air pollution, leading to respiratory diseases.

2. Water pollution: Discharge of industrial effluents, sewage, and plastic waste into rivers (e.g., the Yamuna and Ganga rivers are heavily polluted) makes water unfit for drinking and harms aquatic life.

3. Deforestation: Cutting down of forests for agriculture, construction, and fuel wood reduces forest cover, leading to soil erosion, loss of biodiversity, and disruption of the water cycle.

4. Soil degradation: Excessive use of chemical fertilisers and pesticides in agriculture depletes soil fertility and contaminates groundwater.

5. Groundwater depletion: Over-extraction of groundwater for irrigation (especially in Punjab and Haryana) has led to a sharp fall in the water table.

6. Solid waste and plastic pollution: Improper disposal of garbage and single-use plastics clogs drains, pollutes land and water bodies, and harms animals.

7. Noise pollution: Excessive noise from traffic, loudspeakers, and construction activities causes stress and hearing problems.

8. Loss of biodiversity: Destruction of natural habitats due to urbanisation and industrialisation has led to the extinction or endangerment of many plant and animal species.

Conclusion: Environmental degradation is a serious threat to sustainable development. It affects not only the present generation but also the ability of future generations to live a healthy and productive life.

Note: Table 1.6 referred to in this question is the comparative data table from the NCERT textbook (Chapter 1 — Development) showing indicators for various countries including India, Sri Lanka, China, Nepal, Bangladesh, Pakistan, and others. The key indicators typically included are: Per Capita Income (GNI), Life Expectancy at Birth, Mean Years of Schooling, and HDI Rank.

Based on the standard NCERT Table 1.6 (Comparative Development Indicators):

General Observation:

• Sri Lanka consistently appears at the top (best performance) among India's neighbouring countries on most human development indicators.
• Nepal or Bangladesh generally appears at the bottom (lowest performance) on most indicators.

Students are advised to refer to the actual Table 1.6 in their NCERT textbook and fill in the exact figures for each indicator to give a precise answer, as the table values are updated periodically.

(i) Comparison of Nutritional Level of People in Kerala and Madhya Pradesh:

Given Data:

• Kerala: 8.5% of males and 10% of females have BMI below normal.
• Madhya Pradesh: 28% of males and 28% of females have BMI below normal.

Analysis:

A BMI below 18.5 kg/m² indicates undernutrition. The higher the percentage of people with below-normal BMI, the worse the nutritional status.

• In Kerala, only 8.5% of males and 10% of females are undernourished. This is significantly below the national average (20% males, 23% females), indicating a good nutritional status.

• In Madhya Pradesh, 28% of both males and females are undernourished. This is well above the national average, indicating a poor nutritional status.

Conclusion: The nutritional level of people in Kerala is far better than in Madhya Pradesh. Madhya Pradesh has more than three times the proportion of undernourished males compared to Kerala. This reflects Kerala's better public health infrastructure, higher literacy (especially female literacy), and more effective implementation of food security programmes.

(ii) Why are around one-fifth of people in India undernourished despite enough food being available?

This is a paradox — India produces enough food grain to feed its entire population, yet a large proportion of people remain undernourished. The reasons are:

1. Poverty and lack of purchasing power: Many people, especially daily wage labourers and marginal farmers, do not earn enough to buy adequate nutritious food. Having food available in the market does not help if people cannot afford it.

2. Unequal distribution of food: Food production may be sufficient at the national level, but it is not distributed equally. Food surpluses in some regions coexist with shortages and hunger in others.

3. Inefficiency in the Public Distribution System (PDS): The government's food distribution system (ration shops) suffers from corruption, leakages, and poor implementation. Food meant for the poor often does not reach them.

4. Lack of awareness about nutrition: Even when food is available, people may not consume a balanced diet due to lack of nutritional awareness. They may eat enough calories but lack proteins, vitamins, and minerals.

5. Social inequalities: Marginalised groups such as Scheduled Castes, Scheduled Tribes, and women (especially in rural areas) often have less access to food due to social discrimination and gender inequality.

6. Unemployment and irregular income: Seasonal unemployment and irregular wages mean that many families cannot afford two square meals a day throughout the year.

7. Food wastage: A significant amount of food is wasted due to poor storage facilities, lack of cold chains, and wastage at the consumer level.

Conclusion: The problem of undernutrition in India is not primarily a problem of food production but of access, distribution, poverty, and governance. Ensuring that every person has the economic means and physical access to adequate and nutritious food is essential for eliminating undernutrition.
