Chapter 1 Important Questions: Natural Resources and Their Use

✔ Correct Answer: (b) Materials and substances that occur in Nature and are valuable to humans

Natural resources are elements of Nature that humans use for sustenance or to create new things. They must be technologically accessible, economically feasible, and culturally acceptable to be called resources.

✔ Correct Answer: (c) It must be created by humans

Natural resources are not created by humans — they occur in Nature. The three conditions required are technological accessibility, economic feasibility, and cultural acceptability.

✔ Correct Answer: (d) Coal

Coal is a fossil fuel formed over millions of years and cannot be replenished at the rate we use it, making it a non-renewable resource. Solar energy, wind energy, and timber are renewable resources.

✔ Correct Answer: (c) Countries rich in natural resources sometimes experience slower economic growth

The 'natural resource curse' describes how having abundant natural resources does not automatically make a country prosperous, often because economies fail to develop industries that convert resources into higher-value products.

✔ Correct Answer: (c) Sikkim

In 2016, Sikkim became a $\textbf{100\%}$ organic state, serving as a global model for sustainable agricultural practices. Farmers' incomes grew by about 20% on average and local biodiversity flourished.

✔ Correct Answer: (c) France

The International Solar Alliance was launched by India and France in 2015 as a coalition of sunshine-rich countries committed to harnessing solar power, especially for developing nations.

✔ Correct Answer: (b) Natural processes of the ecosystem that benefit humans

Ecosystem services are benefits humans receive from natural processes — for example, a forest filtering water, preventing soil erosion, and supporting pollinators are ecosystem services that humans benefit from.

✔ Correct Answer: (c) Kaveri

The sharing of Kaveri River water among Karnataka, Tamil Nadu, Kerala, and Puducherry is a well-known example of how natural resources that cross political boundaries can create tensions requiring careful negotiation and management.

✔ Correct Answer: (d) 80%

Almost $\textbf{80\%}$ of Punjab's area has been classified as 'over-exploited', meaning groundwater has been drawn at a rate far greater than the rate at which its restoration and rejuvenation is possible.

✔ Correct Answer: (b) Study and care of plants and trees

Vṛikṣhāyurveda comes from the Sanskrit words vṛikṣha (tree) and ayurveda (science of life), making it an ancient Indian botanical science focused on the study and sustainable care of plants and trees.

Regenerative. A regenerative economy repurposes used resources, minimises waste, and replenishes depleted resources, operating in harmony with Nature's own principles of restoration and recycling.

Renewable. Renewable resources are those that can be restored and regenerated by Nature over time, provided that the natural rhythm of restoration is not disturbed through overexploitation.

Biodiversity. Biodiversity loss refers to the decline in the variety of life on Earth, which is one of the serious consequences of irresponsible treatment of natural resources, along with pollution and climate change.

Rajasthan. The Bhadla Solar Park in Rajasthan is a symbol of India's solar ambitions and can generate enough electricity to power about 15% of Rajasthan's current energy needs.

Surapala. Surapala's Vṛikṣhāyurveda (around the 10th century CE) is a key text in this ancient knowledge system, containing detailed recommendations on soil types, seed collection, irrigation techniques, and pest management.

False. For an entity to be called a natural resource, it must be technologically accessible and economically feasible to exploit; petroleum that cannot be accessed due to lack of technology or prohibitive cost does not qualify as a resource yet.

True. Nature's restorative and regenerative cycles ensure that fallen trees decompose through bacteria, fungi, and insects, enrich the soil, and support new plant growth — a perfect example of a waste-free natural cycle.

False. India has generally avoided the natural resource curse by investing in the development of industries that convert raw resources into higher-value products, though the challenge of balancing extraction with sustainability remains.

False. The high-yielding varieties introduced during the Green Revolution in Punjab required more water than traditional seeds, leading farmers to extract increasing amounts of groundwater to meet this higher demand.

False. A mature tree produces about 275 litres of oxygen per day, while a human being needs about 350 litres per day — so one tree alone is not sufficient to meet one person's daily oxygen requirement.

The mineral found in Jharia, Raniganj, and Bokaro is Coal. These locations in the eastern India (Jharkhand and West Bengal region) are among India's largest coal-bearing areas, as shown by the coal symbol in the map's legend.

The zones where depth to water level is $> 40$ metres below ground level (m bgl) represent the most critically over-exploited groundwater areas. On the map, these are shown by the darkest shade in the index, indicating severe groundwater depletion mostly in central and southern Punjab districts.

Natural resources are materials and substances that occur in Nature and are valuable to humans — they are not created by humans but are used by them for sustenance or to create new things.

Examples: Water (used for drinking and irrigation) and Coal (used as a source of energy).

Restoration is the process of returning something to its original healthy state after it has been degraded — for example, a forest recovering after a wildfire.

Regeneration goes beyond restoration — it refers to Nature's ability to create new life and conditions for thriving, such as new trees growing from seeds and supporting an entirely new ecosystem.

Ecosystem functions are Nature's inherent ways of working — e.g., a forest naturally filtering water and preventing soil erosion.

Ecosystem services are when these natural processes benefit humans — e.g., humans receiving clean drinking water and protected farmland because of that same forest.

Based on their use, natural resources can be categorised as:

Key Points:

• Resources essential for life — air, water, and soil that sustain all living beings

• Resources for energy — coal, petroleum, solar energy, and wind energy that power modern living and industries

Almost $80\%$ of Punjab's area has been classified as 'over-exploited' — groundwater is now inaccessible until depths of about 30 metres, making extraction costly.

Additionally, chemicals from pesticides and fertilisers have dissolved into the groundwater, causing serious health hazards for the population.

The 'natural resource curse', also called the 'paradox of plenty', refers to the phenomenon where regions rich in natural resources sometimes experience slower economic growth rather than prosperity.

This often happens because economies fail to develop the industries and skills needed to convert raw resources into higher-value products.

Vṛikṣhāyurveda is an ancient Indian botanical science that focuses on the study and care of plants and trees — the word comes from vṛikṣha (tree) and ayurveda (science of life).

It was formalised by Surapala around the 10th century CE and contains detailed guidance on soil types, seed preservation, irrigation, and pest management using natural methods.

Key Points:

• Over-extraction of groundwater in Punjab at a rate far greater than replenishment has made groundwater inaccessible at great depths

• Industrial waste discharged into rivers introduces substances that cannot decay naturally, making rivers unable to support life and disrupting the water cycle

Both examples show how human actions break Nature's self-healing cycles.

A renewable resource can become effectively non-renewable when:

Key Points:

• It is harvested faster than Nature can regenerate it — e.g., cutting timber faster than a forest can regrow trees

• Natural cycles are disrupted by human actions — e.g., melting glaciers due to rising temperatures reduce river flow faster than precipitation can replace them, threatening water security

Stewardship of natural resources means acting as responsible caretakers of Nature — using resources in a way that enables the restoration and regeneration of renewable resources and the judicious use of non-renewable ones.

The Bhagavad Gītā's concept of lokasangraha — acting for the wellbeing of all, transcending personal desires — captures this spirit of stewardship.

For an element of Nature to be classified as a natural resource, it must satisfy three conditions:

Key Points:

• Technologically accessible: Humans must have the technology to extract or use it — petroleum miles beneath the ocean that we cannot reach is not yet a resource

• Economically feasible: The cost of extraction and use must be reasonable — a resource too expensive to extract may not be viable

• Culturally acceptable: Its use must not violate cultural or social norms — trees in sacred groves, for example, are not cut even if they could be

$\text{Natural Resource} = \text{Accessible} + \text{Feasible} + \text{Culturally acceptable}$

For example, coal in a mineable area satisfies all three conditions and is thus a natural resource.

Natural resources are not evenly distributed across the planet, and this unevenness shapes human life in significant ways:

Key Points:

• Human settlements and employment: Industries near resource-rich areas create jobs, and townships grow around them — e.g., mining towns in Jharkhand

• Trade patterns: Nations trade resources they have in surplus for those they lack; India's unique resources like Wootz steel historically fuelled trade and the growth of empires

• Conflicts and tensions: Many wars have been fought over control of resources; even within India, the Kaveri river water dispute between Karnataka, Tamil Nadu, Kerala and Puducherry shows how shared resources create political tensions that require careful negotiation

The Brahmaputra, shared by China, India, and Bangladesh, is another example of international resource tension.

Sikkim's transition to 100% organic farming (achieved in 2016) is significant as a global model for sustainable agriculture:

Key Points:

• Process: Pema's family (and others) switched from chemical inputs to compost, natural pest repellents using neem and garlic, and grew multiple crops across the year — though initially yields dropped as the soil recovered

• Outcomes: After about five years, farms thrived; cardamom, ginger, and traditional vegetables fetched premium prices; local biodiversity flourished with beneficial insects and birds returning; and tourism increased

• Economic impact: Farmers' incomes grew by approximately $20\%$ on average

Sikkim demonstrates that sustainable agricultural practices can simultaneously improve both ecological health and economic outcomes.

Cement production is listed among the most polluting industries for several reasons:

Key Points:

• It releases fine dust that damages lungs of humans and animals, settles on plant leaves reducing yields, and causes soil and water pollution

• The process also contributes significantly to carbon emissions

Alternatives being explored include:

• Traditional materials like stone and mud — e.g., Jaisalmer fort (12th century) and the modern Auroville Earth Institute buildings

• New plant-based materials and recycled materials from waste plastic

• Traditional methods combined with modern technology to create sustainable materials that are less polluting, provide local employment, and suit the local climate

The Central Pollution Control Board has also created guidelines to minimise pollution from existing cement factories.

Traditional societies demonstrated deep wisdom in sustainable resource use through several practices:

Key Points:

• Regulated fishing: Indigenous communities traditionally refrained from fishing during the spawning season, allowing fish populations to recover — the commercialisation of fishing ended this and led to over-fishing, as seen with the tuna population crisis

• Sacred groves: In many indigenous traditions, forests or groves were considered sacred, making it culturally unacceptable to cut trees there — this naturally preserved biodiversity

• Traditional water harvesting: Communities built ponds, tanks, and harvesting structures to collect and store rainwater, maintaining water tables and ensuring availability across seasons — practices now being revived to address groundwater depletion

All three practices show that sustainability was embedded in cultural systems long before it became a modern concern.

Renewable vs Non-Renewable Natural Resources

$\text{Renewable Resources} \neq \text{Infinite Resources}$

Why Renewable Resources Are at Risk

Renewable resources remain renewable only if the natural rhythm of restoration is not disturbed. Human actions can push their use beyond Nature's regenerative capacity:

Key Points:

• Timber: If forests are cut faster than they can regrow, they get depleted — deforestation for agriculture has reduced forest cover worldwide

• Groundwater: In Punjab, extraction has exceeded replenishment rates, making groundwater inaccessible at depths of 30 metres across $\approx 80\%$ of the state

• Fish populations: Overfishing of tuna disrupted ocean ecosystems; traditionally, fishing was regulated during spawning seasons to allow recovery

• Glaciers: Rising temperatures (caused by fossil fuel use and deforestation) are melting Himalayan glaciers faster than precipitation can replace them, threatening river flow and water security for millions

What Can Be Done

Key Points:

• Regulate use: Harvest renewable resources only at a rate equal to or below Nature's regeneration rate

• Revive traditional practices: Water harvesting, multi-cropping, sacred groves, and regulated fishing protect resources sustainably

• Organic farming: Sikkim's model shows that transitioning to organic practices restores soil health and biodiversity

• Reduce pollution: Prevent industrial waste from entering rivers and disrupting aquatic ecosystems

• Switch to renewables for energy: Expanding solar and wind energy (e.g., Bhadla Solar Park) reduces pressure on non-renewables and limits climate change that threatens renewable resources

$\text{Sustainable Use Rate} \leq \text{Nature's Regeneration Rate}$

The goal of stewardship is to ensure that both current and future generations can benefit from Nature's gifts.

Categories of Natural Resources Based on Use

Natural resources can be grouped into three categories based on how humans use them:

1. Resources Essential for Life

Without these, life on Earth cannot exist:

Key Points:

• Air: We breathe oxygen from the atmosphere; humans need approximately 350 litres of oxygen daily

• Water: Obtained from rivers, ponds, and groundwater; used for drinking, sanitation, and agriculture

• Soil: Provides the medium for growing food crops

$\text{Life} \Rightarrow \text{Air} + \text{Water} + \text{Soil (Food)}$

These cannot be manufactured by humans — we depend entirely on Nature for them.

2. Resources for Materials

Humans create physical objects from Nature's raw materials for utility and beauty:

Key Points:

• Timber is used for furniture, construction, and art

• Marble and stone are used for buildings and sculptures

• Gold, copper, iron are used in jewellery, tools, and machinery

• India's geographical diversity — from the forests of the Northeast to the marble deposits of Rajasthan — provides an enormous variety of such materials

• Unique products like Wootz steel combined natural resources with human knowledge and skills, enabling global trade

3. Resources for Energy

Energy is the cornerstone of modern living:

India's Geographical Diversity and Resource Richness

India's varied geography — the Himalayan ranges, the Deccan Plateau, the coastal plains, and the Indo-Gangetic Plains — makes it exceptionally resource-rich:

Key Points:

• Coal deposits in Jharkhand and West Bengal (Jharia, Raniganj, Bokaro)

• Iron ore in Odisha, Chhattisgarh, and Karnataka (Kudremukh, Ballari)

• Petroleum offshore in Mumbai High and in Assam (Digboi, Naharkatia)

• Solar energy potential especially in Rajasthan

• Forests providing timber, water regulation, and biodiversity in the Northeast and Western Ghats

By developing industries to process these resources (thus avoiding the resource curse) and adopting sustainable practices, India can ensure that these natural gifts benefit both present and future generations.

Groundwater Crisis in Punjab: A Case Study

Background

Punjab, once celebrated for the Green Revolution that helped India achieve food self-sufficiency, today faces a severe groundwater depletion crisis — a stark example of a renewable resource pushed beyond its regenerative capacity.

Causes of the Crisis

Key Points:

• Introduction of high-yielding varieties (HYVs) of wheat and paddy in the 1960s required significantly more water than traditional seed varieties

• Free/subsidised electricity supply encouraged farmers to over-pump groundwater without restriction

• Chemical pesticides and fertilisers used in modern farming dissolved into the groundwater

• Lack of awareness about the long-term consequences of over-extraction

$\text{Extraction Rate} \gg \text{Natural Replenishment Rate} \Rightarrow \text{Depletion}$

Consequences

Measures to Address the Crisis

Key Points:

• Traditional water harvesting: Rejuvenation of ponds and tanks to recharge groundwater

• Reduce wasteful consumption: Adopt drip irrigation and sprinkler systems

• Processing and reusing water: Treat wastewater and reuse it for irrigation

• Shift to less water-intensive crops: Move away from water-hungry paddy in water-stressed areas

• Regulate power supply: End free electricity to discourage over-pumping

• Organic farming transition: Reduce chemical use to prevent further contamination of groundwater

Diagram: Water Table and Groundwater Depletion

Draw the following:

• A cross-section of land showing the surface at the top

• Below the surface: a layer labelled 'Unsaturated Zone (Soil)'

• A dotted horizontal line labelled 'Water Table (original level)'

• Below it: a darker shaded zone labelled 'Saturated Zone (Groundwater)'

• A second dotted line below the first labelled 'Water Table (depleted level, $> 30$ m)' with a downward arrow showing decline

• A vertical pipe/tube going down from the surface labelled 'Tube Well / Pump' reaching the depleted water table

• Label the gap between original and current water table as 'Zone of Depletion'

Conclusion

The Punjab crisis illustrates that food security achieved in the short term can come at the cost of long-term ecological damage. It reinforces the principle that:

$\text{Sustainable Use} = \text{Extraction Rate} \leq \text{Regeneration Rate}$

Responsible stewardship requires balancing present needs with the rights of future generations.

India's Role in Promoting Renewable Energy

Why Transition from Non-Renewable to Renewable Energy?

Non-renewable resources like coal and petroleum are finite:

Key Points:

• India's coal reserves are estimated to last only about 50 more years even as demand increases with population growth and development

• Burning fossil fuels releases pollutants and greenhouse gases, contributing to climate change, glacier melting, and biodiversity loss

• Renewable alternatives — solar, wind, hydropower — are inexhaustible, cleaner, and sustainable

$\text{Fossil Fuels (finite)} \rightarrow \text{Renewable Energy (sustainable)} = \text{Long-term Energy Security}$

India's Domestic Solar Energy Initiatives

The International Solar Alliance (ISA)

Key Points:

• Launched jointly by India and France in 2015 as the International Alliance for Solar Energy (IASE)

• A coalition of sunshine-rich countries committed to harnessing solar power, especially nations with abundant sunlight throughout the year

• India has helped channel billions of dollars into solar projects across developing nations

• The ISA provides technical expertise and creates affordable financing options for solar projects

• It represents both environmental responsibility (reducing fossil fuel dependence) and economic opportunity (jobs, energy access, technology leadership)

Benefits of Renewable Energy Transition

Key Points:

• Environmental: Reduces greenhouse gas emissions, air and water pollution

• Economic: Creates new industries and employment; reduces dependency on imported fossil fuels

• Social: Provides energy access to remote communities (e.g., microhydel plants in mountain villages)

• Strategic: Enhances national energy security and reduces geopolitical vulnerability

• Climate: Slows glacier melt, reduces risk to water security for river-dependent populations

Conclusion

India's leadership in both domestic solar expansion and the International Solar Alliance demonstrates that a developing economy can simultaneously pursue economic growth and environmental stewardship. The shift to renewables is not merely an environmental choice — it is a necessity for ensuring that non-renewable resources last long enough for humanity to build a fully sustainable energy future:

$\text{Responsible Non-Renewable Use} + \text{Accelerated Renewable Adoption} = \text{Energy Security for Future Generations}$

Distribution of Major Mineral Resources in India

Diagram Instructions

Draw an outline map of India and mark/label the following:

Use a legend/key with different symbols or colours for each mineral as shown in Fig. 1.11 of the textbook.

Observations on Distribution

Key Points:

• Mineral distribution is highly uneven — concentrated in specific geological belts

• Coal and iron ore are heavily concentrated in the Chota Nagpur Plateau region (Jharkhand, Odisha, Chhattisgarh)

• Petroleum is found in Assam (northeast) and offshore western coast (Mumbai High)

• Solar energy potential is highest in Rajasthan and Gujarat (not shown as minerals but important for energy map)

Impact on Economic Activities and Human Settlements

$\text{Natural Resources} + \text{Human Knowledge/Skills} \rightarrow \text{Economic Development}$

Key Points:

• Industrial growth: The concentration of coal and iron ore in the Chota Nagpur region led to the growth of steel and heavy industries — cities like Jamshedpur (Tata Steel) and Bokaro (Steel Plant) developed around these resources

• Employment: Industries near natural resources create direct and indirect employment for local people; townships grow, expanding economic opportunities

• Trade: India exports iron ore and imports petroleum products, shaping its trade balance and international relations

• Displacement and conflict: Resource-rich areas have sometimes seen people displaced from homes and sacred places to make way for mines and industries, leading to social conflicts

• Resource curse risk: Regions overly dependent on a single resource can face economic stagnation if that resource is depleted or prices fall

Conclusion

The uneven distribution of natural resources is both an opportunity and a challenge. While it drives industrial growth and trade, it also creates inequalities and environmental pressures. Wise governance, equitable distribution of benefits, and sustainable extraction practices are essential to ensure that natural resource wealth translates into lasting prosperity:

$\text{Resource Wealth} + \text{Good Governance} + \text{Sustainability} = \text{Lasting Prosperity}$
