Chapter 1
Natural Resources and Their Use
We must move toward a regenerative economy, an economy that operates in harmony with nature, repurposing used resources, minimizing waste, and replenishing depleted resources. We must return to the innate wisdom of nature herself, the ultimate regenerator and recycler of all resources. ― Christiana Figueres and Tom Rivett-Carnac, The Future We Choose

When Does Nature Become a Resource?
One of the meanings of the word ‘Nature’ is the totality of life and non-life forms that are part of our environment but have not been created by humans. When humans use these for their sustenance, or create new things from them for consumption, these elements of Nature become ‘resources’.
Example: Trees are part of the environment. When we cut them and convert their wood into furniture, we see the trees as a resource.
For an entity to be called a resource, three conditions must be met:
| Condition | Meaning | Example |
|---|---|---|
| Technologically Accessible | We must have the technology to extract/use it | Deep ocean petroleum not yet accessible = not yet a resource |
| Economically Feasible | Extraction cost must be practical | If extraction costs more than the resource’s value, it’s not feasible |
| Culturally Acceptable | Society must not prohibit its use | Cutting trees in sacred groves is culturally unacceptable |
The Earth has treasures — many formed over millions of years — that humans have learnt to use: water, air, soil, coal, petroleum, precious stones, metal ores, timber, etc.
Take a pause. Look at yourself and the things around you. What is the origin of each of them? At some point they all lead to Nature — even the plastic button on your shirt.
- In many indigenous traditions of the world, Nature is considered sacred. Nature is seen as a nurturer and nourisher, not merely a resource.
- Traditional practices like the Tulasī puja (worship of the Tulsi plant) or offering arghyam to Sūrya (water to the sun god) reflect this deep reverence.
- This worldview often led to conservation practices that protected ecosystems — sacred groves (Devavans), restrictions on hunting during certain seasons, etc.
In short, we apply the term ‘natural resources’ to materials and substances that occur in Nature and are valuable to humans.
Categories of Natural Resources
| Category | Description | Examples |
|---|---|---|
| Resources Essential for Life | Life cannot exist without these | Air (atmosphere), Water (rivers, ponds), Soil (food cultivation) |
| Resources for Materials | Used to create physical objects for utility or beauty | Wood → furniture/statuette; Marble, Coal, Gold |
| Resources for Energy | Cornerstone of modern living — electricity, transport, production | Coal, Water, Petroleum, Natural gas, Sunlight, Wind |
A second categorisation is based on whether resources can replenish themselves:
Key Principle of Nature
- Restoration: Returning something to its original healthy state after degradation (a cut on skin heals; a forest recovers after wildfire)
- Regeneration: Goes beyond restoration — Nature’s ability to create new life and conditions for thriving
- Nature works in cycles with no waste: a fallen tree decomposes → enriches soil → new trees grow → cycle repeats
Renewable Resources
Renewable resources exhibit Nature’s restorative and regenerative characteristics over time. They can be replenished naturally.
| Renewable Resource | How It Renews |
|---|---|
| River Water | Fed by rain and melting glaciers (conditional — glaciers must exist) |
| Solar Energy | Inexhaustible as long as the sun exists |
| Wind Energy | Driven by atmospheric processes, perpetually available |
| Timber (Forest) | Forests regenerate if harvesting is within sustainable limits |
| Soil | Replenishes through natural processes (organic matter, microbes) |
| Fish Populations | Replenish through spawning if not over-fished |
For resources to remain renewable, the natural rhythm of restoration and regeneration must not be disturbed. If we harvest timber faster than the forest can grow trees, we will eventually deplete the forest — making it effectively non-renewable.
- Traditionally, communities had a system of regulating or refraining from fishing during the spawning season to enable maintenance of fish population.
- Commercialisation of fishing led to over-fishing.
- Tuna fish: rapid and extensive decline in population led to some international agreements on fishing control. Yet this species, critical for ocean ecosystem balance (consumes smaller fish, shrimps), is still on a decline.
- Ecosystem Functions vs Ecosystem Services: A forest naturally filters water, prevents soil erosion, provides habitat — these are ecosystem functions. When we benefit from clean water, protected farmland, pollinated crops — these are ecosystem services.
- A mature tree produces about 275 litres of oxygen per day. A human being needs about 350 litres of oxygen every day.
Scientists have shown that irresponsible human actions have disturbed many of Nature’s cycles. Fossil fuel-driven industrialisation and large-scale deforestation have contributed to rising temperatures, causing Himalayan glaciers to melt faster than precipitation can replace them — threatening water security for hundreds of millions in the plains.
- Industries produce goods we consume but the process also creates wastes frequently discharged into rivers and water bodies.
- These wastes often cannot decay to become food for any lifeform, disturbing Nature’s cycle of restoration and regeneration.
- This leads to rivers becoming poisonous and unable to support life.
Non-Renewable Resources
Non-renewable resources are created over long geological periods. They cannot be replenished at the rate we use them.
| Non-Renewable Resource | Key Facts |
|---|---|
| Coal | India has significant reserves; estimated to last another ~50 years at current demand. Demand rising with population growth and development acceleration. |
| Petroleum (Crude Oil) | Fossil fuel, formed over millions of years from organic matter under pressure and heat |
| Iron | Metal ore, mined; cannot be replenished |
| Copper | Metal ore, limited deposits globally |
| Gold | Precious metal; finite in quantity |
Till more sustainable options become widely available, we need to use these resources judiciously.
Distribution of Natural Resources & Its Implications
Natural resources are not evenly distributed across our planet or even within countries. This uneven distribution shapes:
- Human settlements and population patterns
- Trade patterns (national and international)
- International relations and diplomacy
- Conflicts — many wars have been fought, and continue to be fought, to gain control over natural resources
| Mineral | Important Locations |
|---|---|
| Coal | Jharia (Jharkhand), Bokaro (Jharkhand), Raniganj (West Bengal), Talcher (Odisha), Singhareni (Telangana), Korba (Chhattisgarh), Bilaspur (Chhattisgarh), Neyveli (Tamil Nadu — lignite), Bailadila (Chhattisgarh) |
| Oil / Petroleum | Mumbai High (offshore), Bassein (offshore), Ankleshwar (Gujarat), Kalol (Gujarat), Digboi (Assam — first oil well in Asia), Naharkatia, Moran, Hugrijan, Makum, Janji (all Assam) |
| Iron Ore | Gua, Mayurbhanj, Keonjhar (Odisha/Jharkhand), Ratnagiri (Maharashtra), Goa, Ballari (Karnataka), Chitradurga, Tumkur, Chikkamagaluru, Kudremukh (Karnataka), Chandrapur (Maharashtra), Durg (Chhattisgarh), Koraput (Odisha) |
| Bauxite | Katni (Madhya Pradesh), Amarkantak (MP/Chhattisgarh), Korba (Chhattisgarh), Koraput (Odisha) |
- Industries near natural resources create employment opportunities for local people
- Townships grow around industries, expanding economic opportunities
- Modern facilities (healthcare, education) improve quality of life
- However, people in resource-rich areas are often displaced from their homes to facilitate developments
- Sacred places of indigenous/tribal communities come under threat, leading to conflicts
National and international trade depend on the geographical location of natural resources. Combined with human knowledge and skills, these can create unique products. The famous Wootz steel (from ancient India) is a classic example — iron ore combined with Indian metallurgical knowledge created a product of extraordinary quality traded globally. As we know, trade fuelled the development of large empires in India.
Nature does not pay attention to political boundaries. This leads to tensions regarding sharing of natural resources across states and countries.
- Cauvery (Kaveri) River water is shared among Karnataka, Tamil Nadu, Kerala and Puducherry. Negotiations and deft management were required to maintain peace and fair sharing.
- The Brahmaputra is a classic trans-boundary river dispute.
- Originates as Yarlung Tsangpo in Tibet (China) → enters India as Brahmaputra in Arunachal Pradesh/Assam → enters Bangladesh as Jamuna.
- China’s dam-building activities on the Yarlung Tsangpo (proposed world’s largest hydropower dam) is a major India-China concern — affects downstream water availability and flood patterns.
- Reaching inter-country water-sharing agreements is much harder than inter-state ones.
The Natural Resource Curse
Having abundant natural resources does not guarantee economic prosperity.
This happens because:
- Economies become over-dependent on raw material exports
- They are unable to develop industries that convert resources into higher-value products (value addition / manufacturing)
- Revenue from resources is often mismanaged or leads to corruption
- Other sectors of the economy are neglected (Dutch Disease)
India has generally avoided this curse by investing in the development of industries to meet growing needs. Understanding and managing natural resources is a valuable starting point, but human knowledge, good governance, and strategic planning determine whether resources become lasting benefits or temporary windfalls.
- Classic examples of resource curse: Nigeria (oil-rich, poverty-ridden), DRC Congo (mineral-rich, conflict-ridden)
- Contrast: Japan, South Korea — resource-poor but knowledge-rich → became economic powerhouses
- Mettur Dam (Tamil Nadu) on Kaveri river — example of resource utilisation for development
Responsible and Wise Use: Stewardship
Sustaining life on Earth requires that we respect Nature and use natural resources in a way that enables:
- Restoration and regeneration of renewable resources
- Responsible and judicious use of non-renewable resources
Scientists have warned that irresponsible treatment of natural resources has led to:
- Pollution of air, water, and soil
- Biodiversity loss — decline in the variety of life on Earth
- Climate change — accelerating at an increased pace in recent years
- The Bhagavad Gītā refers to lokasangraha — the idea that everyone must transcend personal desires and act for the wellbeing of all.
- This ancient Indian concept aligns perfectly with modern sustainability ethics — individual actions must consider collective and intergenerational welfare.
We need to ensure that we use non-renewable resources so that they last long enough for humanity to find more sustainable alternatives. The primary strategy is to switch to renewable sources of energy for as many purposes as possible.
Overexploitation of Groundwater — Punjab Caselet
Punjab was home to the Green Revolution that made India self-sufficient in food. Today, the same state faces a groundwater crisis.
| Cause | Details |
|---|---|
| High-Yielding Varieties | From the 1960s, farmers shifted to HYV of wheat and paddy which required far more water than traditional seeds |
| Free Power Supply | Supply of free electricity led to over-pumping of groundwater — a situation still prevalent across much of India today |
| Chemical Inputs | Modern farming required chemical pesticides and fertilisers, which dissolved in groundwater causing health hazards |
- Groundwater level in large parts of Punjab now inaccessible until depths of ~30 metres
- Chemicals from pesticides and fertilisers have dissolved into groundwater → health hazards
- Almost 80% of Punjab’s area has been classified as ‘overexploited’ — water drawn at a rate much greater than restoration and rejuvenation is possible
- This concern is not particular to Punjab — it affects many other states too
| Colour in Map | Depth to Water Level | Status |
|---|---|---|
| Dark Blue | 0–2 metres | Shallow — easy access (mainly SW Punjab: Fazilka, Muktsar area) |
| Medium Blue | 2–5 metres | Relatively shallow |
| Light Blue/Purple | 5–10 metres | Moderate |
| Light Pink | 10–20 metres | Deeper — stress beginning |
| Red | 20–40 metres | Severely depleted — central and eastern Punjab |
| Dark Red | >40 metres | Critically depleted — Ludhiana, Sangrur, Patiala belt |
- Traditional practices of water harvesting
- Rejuvenation of ponds and tanks
- Cutting down on wasteful consumption of water
- Processing and reusing water
- Initiatives to raise groundwater levels have been launched
The improper use of chemical fertilisers and pesticides has led to soil degradation. Traditional farming practices considered soil to be part of Mother Earth. Practices like cow dung and natural fertilisers, mulching, multi-cropping enabled holistic soil management. We must learn from these practices.
The Case of Cement
Cement is indispensable for houses, schools, hospitals, bridges, roads and airports. However, cement production is listed as one of the most polluting industries.
- Releases fine dust that enters lungs of humans and animals, damaging them
- Dust settles on leaves of plants, decreasing their yields
- Causes soil and water pollution
- The Central Pollution Control Board (CPCB) has created guidelines for cement factories to minimise or eliminate pollution
- Traditional materials: Stone and mud (example: Jaisalmer Fort — built in 12th century using mud, later refurbished with sandstone)
- New plant-based materials
- Recycled materials from waste plastic
- Example: Auroville Earth Institute (UNESCO Chair for Earthen Architecture) — constructs modern buildings using mud with special techniques, sustainable and climate-appropriate
Traditional materials and methods are being combined with modern technological advances to create new materials that are sustainable — less polluting, provide local employment, and are designed keeping in mind the climate of the place.
Vṛikṣhāyurveda — Ancient Indian Botanical Science
This traditional knowledge system dates back several millennia and was formalised in texts such as Surapala’s Vṛikṣhāyurveda around the 10th century CE.
| Aspect | Details |
|---|---|
| Soil-Plant Matching | Elaborate recommendations on specific plants to be grown on different soil types |
| Seed Management | Intricate methods for seed collection, preservation, and pre-planting treatments |
| Irrigation | Elaborately described techniques, varying by plant species, growth stage, and seasonal conditions |
| Pest Management | Natural repellents; companion planting (plants that should be grown together) |
| Sustainable Agriculture | Crop rotation and mixed cropping to maintain soil health |
| Ploughing Methods | Proper methods to retain soil moisture and facilitate growth of fungi, bacteria and earthworms in soil |
- Vṛikṣhāyurveda is an example of traditional ecological knowledge (TEK) — a recurring theme in Environment and GS-I questions.
- It aligns with modern agroecology and permaculture principles.
- Government of India has been promoting traditional agricultural practices through schemes like Paramparagat Krishi Vikas Yojana (PKVY) for organic farming.
Sikkim Organic Farming — A Caselet
Pema’s family farm in Sikkim faced declining yields and mounting debts from expensive chemical inputs.
| Stage | What Happened |
|---|---|
| Challenge | Declining yields + high debt from chemical inputs |
| Government Policy | State government announced policy to promote organic farming statewide |
| Initial Difficulty | Yields initially dropped as soil was recovering from years of chemical use |
| New Practices | Switched to compost; natural pest repellents using neem and garlic; multiple crops across the year |
| Outcome (after 5 years) | Farm thriving; cardamom, ginger, traditional vegetables sold at premium prices |
| 2016 Milestone | Sikkim became India’s first 100% organic state — all farmland certified organic |
- Local biodiversity flourished — beneficial insects and birds returned
- Tourism increased as visitors came to see the organic farming model
- Farmers’ incomes grew by 20% on average
- Sikkim now serves as a global model for sustainable agricultural transition
- Sikkim became India’s first fully organic state in 2016.
- Awarded the UN’s Future Policy Gold Award 2018 for its organic mission.
- Shows that entire regions can transition to sustainable agriculture while improving both ecological and economic outcomes.
Renewable Energy & International Solar Alliance
The Bhadla Solar Park in Rajasthan is one of the world’s largest solar parks. According to NCERT (Fig. 1.21), it can generate enough electricity to power about 15% of the current needs of Rajasthan.
| Aspect | Details |
|---|---|
| Full Name | International Alliance for Solar Energy (IASE) / International Solar Alliance (ISA) |
| Founded | 2015 — jointly launched by India and France at COP21 Paris |
| Focus | Countries with abundant sunlight (sunshine-rich countries) committed to harnessing solar power |
| India’s Role | Helped channel billions of dollars into solar projects across developing nations; shared technical expertise; created affordable financing options |
| Significance | Represents both environmental responsibility and economic opportunity for India |
| Headquarters | Gurugram, India |
- The distribution and access to resources, including basic ones like water and clean air, is often unfair to some sections of society.
- In cities, many areas do not receive adequate and regular supply of drinking water.
- Air pollution caused by industries and excessive use of fossil fuels affects those who are unable to protect themselves from these hazards (environmental justice dimension).
- Solar farm near Raichur, Karnataka mentioned in the NCERT as an example (Fig. 1.22).

Practice MCQs
UPSC & State PCS Standard | Chapter 1 — Natural Resources and Their Use
Click “Show Answer” below each question to reveal the correct answer and explanation.
- A.It must be technologically accessible
- B.Its exploitation must be economically feasible
- C.It must be found in large quantities
- D.Its use must be culturally acceptable
Show Answer
According to NCERT, the three conditions are: (1) technologically accessible, (2) economically feasible, and (3) culturally acceptable. There is no requirement that the resource must be abundant. Even a rare mineral that meets the three conditions qualifies as a resource.
- A.Ecosystem functions are human-created; ecosystem services are natural
- B.Ecosystem functions are Nature’s inherent processes; ecosystem services are the benefits humans derive from them
- C.Ecosystem functions refer only to forests; ecosystem services refer to oceans
- D.Both terms mean the same thing in ecology
Show Answer
As per NCERT: a forest naturally filters water, prevents soil erosion, provides habitat for animals — these are ecosystem functions. When we benefit from clean water, protected farmland, and pollinated crops because of that forest, we are receiving ecosystem services. Functions exist independently of humans; services are about human benefit.
- A.Indus
- B.Ganga
- C.Brahmaputra
- D.Teesta
Show Answer
The Brahmaputra is called Yarlung Tsangpo in Tibet (China), flows into India as Brahmaputra through Arunachal Pradesh and Assam, and enters Bangladesh where it is called Jamuna. It is a classic example of a trans-boundary river and a subject of India-China water diplomacy, especially given China’s plans to build dams on the upper Yarlung Tsangpo.
- A.Kerala
- B.Uttarakhand
- C.Mizoram
- D.Sikkim
Show Answer
In 2016, Sikkim became India’s first 100% organic state with all its farmland certified organic. The effects were transformational — local biodiversity flourished, tourism increased, and farmers’ incomes grew by 20% on average. Sikkim was also awarded the UN Future Policy Gold Award 2018 for its organic farming mission.
- A.USA
- B.Germany
- C.France
- D.Australia
Show Answer
India and France jointly launched the International Solar Alliance (originally called International Alliance for Solar Energy — IASE) in 2015 at COP21 in Paris. It is a coalition of sunshine-rich countries committed to harnessing solar power. ISA’s headquarters are in Gurugram, India.
- A.Countries with many natural resources tend to have more wars
- B.Resource-rich regions often experience slower economic growth than resource-poor ones
- C.Natural resources become exhausted faster in developing countries
- D.Renewable resources are more valuable than non-renewable ones
Show Answer
The ‘Natural Resource Curse’ is the paradox where regions/countries with abundant natural resources tend to have less economic growth and development than resource-poor countries. This happens because economies become over-dependent on raw material exports and fail to develop value-adding industries. India has generally avoided this curse by investing in industrial development. Option A describes conflict resource theory (related but different); Options C and D are incorrect.
- A.40%
- B.60%
- C.80%
- D.95%
Show Answer
As per NCERT, almost 80% of the area of Punjab has been classified as ‘overexploited’ — water has been drawn at a rate much greater than at which restoration and rejuvenation of groundwater is possible. This crisis grew from the Green Revolution era (1960s) when HYV crops requiring more water were introduced, combined with free electricity supply that led to over-pumping.
- A.Recommendations on plants suitable for different soil types
- B.Pest management through natural repellents and companion planting
- C.Instructions for building mud houses and structures
- D.Methods of ploughing to retain soil moisture
Show Answer
Vṛikṣhāyurveda covers: soil-plant matching, seed management, irrigation techniques, natural pest management, crop rotation/mixed cropping (sustainable agriculture), and ploughing methods to retain soil moisture and support soil microorganisms. It does not deal with building construction. Building with mud is illustrated by the Jaisalmer fort example in a separate context in the same chapter.
- A.Brahmaputra (India) → Yarlung Tsangpo (Tibet) → Jamuna (Bangladesh)
- B.Yarlung Tsangpo (Tibet) → Brahmaputra (India) → Jamuna (Bangladesh)
- C.Jamuna (Bangladesh) → Brahmaputra (India) → Yarlung Tsangpo (Tibet)
- D.Yarlung Tsangpo (Tibet) → Jamuna (Bangladesh) → Brahmaputra (India)
Show Answer
The correct flow: Originates in Tibet as Yarlung Tsangpo → enters India (Arunachal Pradesh, then Assam) as Brahmaputra → enters Bangladesh where it is called Jamuna → eventually joins the Ganga-Padma and meets the Bay of Bengal. This river crosses three international boundaries, making water-sharing a major diplomatic issue.
- A.Coal — Jharia (Jharkhand)
- B.Oil — Digboi (Assam)
- C.Iron Ore — Kudremukh (Karnataka)
- D.Bauxite — Bokaro (Jharkhand)
Show Answer
Bokaro (Jharkhand) is known for Coal (and also has a major steel plant), not Bauxite. Bauxite deposits shown in the NCERT map are at Katni (MP), Amarkantak (MP/CG), Korba (CG), and Koraput (Odisha). All other pairs are correct: Jharia is a major coalfield; Digboi (Assam) is the site of Asia’s first oil well (1889); Kudremukh (Karnataka) is a major iron ore region.
- A.Karnataka, Tamil Nadu, Andhra Pradesh, and Telangana
- B.Karnataka, Tamil Nadu, Kerala, and Puducherry
- C.Karnataka, Maharashtra, Goa, and Tamil Nadu
- D.Karnataka, Tamil Nadu, and Kerala only
Show Answer
As specifically mentioned in NCERT: the sharing of Kaveri River water is among Karnataka, Tamil Nadu, Kerala, and Puducherry. Puducherry (a Union Territory) has delta areas irrigated by the Cauvery, hence it is also a party to the dispute. This is adjudicated by the Cauvery Water Disputes Tribunal (final award: 2007; modified by Supreme Court in 2018).
- A.Sustainable Urban Planning
- B.Earthen Architecture
- C.Organic Agriculture
- D.Renewable Energy Integration
Show Answer
The Auroville Earth Institute holds the UNESCO Chair for Earthen Architecture. It constructs modern buildings using mud with special techniques — demonstrating that traditional building materials (mud/earth) can be used sustainably in contemporary construction, reducing reliance on polluting cement. Auroville is located near Pondicherry (Puducherry), Tamil Nadu.
- A.100 litres
- B.175 litres
- C.275 litres
- D.350 litres
Show Answer
NCERT states a mature tree produces about 275 litres of oxygen per day (this varies by tree type). A human being needs about 350 litres of oxygen every day. This means a single tree cannot fully support one human’s oxygen needs — highlighting why forests (large numbers of trees) are critical for human survival. Option D (350 litres) is the human requirement, not what the tree produces.
- A.Ahimsa
- B.Dharma
- C.Lokasangraha
- D.Karma
Show Answer
The NCERT explicitly references lokasangraha from the Bhagavad Gītā — the idea that everyone must transcend personal desires and act for the wellbeing of all. In the context of resource stewardship, this means individuals must consider the collective and intergenerational welfare in resource use, not just personal gain. This aligns closely with the UN’s concept of sustainable development (meeting present needs without compromising future generations’ ability to meet theirs).
- A.Returning a degraded resource to its original state
- B.Nature’s ability to create new life and conditions for thriving — going beyond restoration
- C.Converting non-renewable resources into renewable ones through technology
- D.Government schemes to restore polluted rivers
Show Answer
NCERT distinguishes restoration from regeneration: Restoration = returning something to its original healthy state after degradation (a cut on skin heals; a forest recovers after wildfire). Regeneration = goes beyond restoration — it is Nature’s ability to create new life and the conditions for thriving. Option A describes restoration, not regeneration. The distinction is important for ecology questions.
- A.Gujarat
- B.Madhya Pradesh
- C.Karnataka
- D.Rajasthan
Show Answer
The Bhadla Solar Park is located in Rajasthan. According to NCERT (Fig. 1.21), it can generate enough electricity to power about 15% of the current needs of Rajasthan. It is a symbol of India’s solar ambitions, demonstrating how a country can transition from traditional energy sources to renewable alternatives. NCERT also mentions a solar farm near Raichur, Karnataka (Fig. 1.22).
- A.It is India’s largest coal producing area
- B.It is the site of Asia’s first oil well
- C.It has India’s largest bauxite reserves
- D.It is where India’s first nuclear plant was set up
Show Answer
Digboi in Assam is historically significant as the site of Asia’s first oil well, drilled in 1889. It is marked on the NCERT mineral distribution map as an oil location. The Digboi oil refinery (established 1901) is also one of India’s oldest refineries still in operation today. Other oil locations in Assam on the NCERT map include Naharkatia, Moran, Hugrijan, Makum, and Janji.
- A.Leather tanning
- B.Coal mining
- C.Cement production
- D.Textile dyeing
Show Answer
NCERT specifically mentions that the Central Pollution Control Board (CPCB) has created guidelines for cement factories to ensure pollution is minimised or eliminated. Cement production releases fine dust that damages lungs of humans and animals, reduces plant yields, and causes soil and water pollution. Cement is listed as one of the most polluting industries.
- A.Shift from irrigation to rain-fed agriculture
- B.Adoption of High-Yielding Variety seeds requiring more water and chemical inputs
- C.Introduction of organic farming methods across Punjab
- D.Shift from paddy cultivation to dryland crops like millets
Show Answer
From the 1960s, farmers shifted to High-Yielding Varieties (HYV) of wheat and paddy. These required far more water than traditional seeds → farmers began extracting groundwater. The supply of free power led to over-pumping. Modern farming also required chemical pesticides and fertilisers. The combined effect: 80% of Punjab overexploited for groundwater and chemical contamination of groundwater causing health hazards.
- A.Wootz steel was produced by combining iron ore with coal, both mined from the Deccan plateau
- B.Wootz steel demonstrates how natural resources combined with human knowledge and skills can create unique high-value products
- C.Wootz steel was imported into India and adapted by Indian craftsmen
- D.Wootz steel is an example of the natural resource curse
Show Answer
NCERT uses Wootz steel as an example of how national and international trade depends on the geographical location of natural resources, and how resources combined with human knowledge and skills can create unique products. Wootz (also called Damascus steel) was an ancient Indian high-carbon steel renowned globally for its strength and distinctive pattern. It was exported widely and used to make legendary swords. It demonstrates the concept of value addition to natural resources through knowledge.
- A.Only 1 is correct
- B.Only 1 and 2 are correct
- C.Only 2 and 3 are correct
- D.All three are correct
Show Answer
Statements 1 and 2 are correct: Farmers’ incomes grew by 20% on average (NCERT); Sikkim received UN Future Policy Gold Award 2018 (value addition). Statement 3 is INCORRECT — NCERT explicitly states the transition was not easy: “initially the yields dropped as the soil was recovering from years of chemical use.” Only after about five years did the farm thrive. This is an important fact about organic transition challenges.
- A.A river that was heavily polluted but is now cleaned and supports aquatic life again
- B.A solar panel generating electricity using sunlight
- C.A mine being excavated to extract coal
- D.Wind turbines generating electricity in coastal areas
Show Answer
Restoration = returning something to its original healthy state after it has been degraded or damaged. A polluted river being cleaned and restored to support life is restoration. Options B and D are examples of harnessing renewable energy (not restoration/regeneration). Option C is resource extraction (opposite of restoration). Regeneration would be the river ecosystem then creating new populations of fish and species — going beyond mere restoration.
