1. Chapter Overview

Chapter 1, Natural Resources and Their Use, explores how elements of Nature become resources when humans use them, how natural resources can be categorised, why their distribution matters, and what happens when they are used faster than Nature can restore or regenerate them.

Big Question 1

How do we categorise natural resources?

Big Question 2

How does the distribution of natural resources affect different aspects of life?

Big Question 3

What are the implications of unsustainable use or over-exploitation?

Central idea

Resources should be used responsibly so that renewable resources can regenerate and non-renewable resources last longer.

Chapter theme: India and the World: Land and the People. The chapter connects geography, economics, society, environment and traditional knowledge.

2. When Does Nature Become a Resource?

Nature includes the living and non-living forms that exist in our environment and have not been created by humans. When people use elements of Nature for sustenance or create useful things from them, those elements can become resources.

Example: Tree → Resource

Tree in Nature→Human use→Wood→Furniture / useful object

Three conditions discussed in the chapter

ConditionMeaningExample
Technologically accessibleHumans need suitable technology to access or use the resource.Petroleum deep beneath the ocean may require specialised technology.
Economically feasibleThe resource must be practical to extract or use considering costs and benefits.A resource that costs too much to extract may not be usable at present.
Culturally acceptableIts use should not violate important cultural or social values.Cutting trees in sacred groves may be culturally unacceptable.
Key definition: Natural resources are materials and substances that occur in Nature and are valuable to humans.

Resources around us

  • Air, water and soil are essential for life.
  • Wood, marble, coal, gold and metal ores can provide materials.
  • Coal, petroleum, natural gas, sunlight, wind and flowing water can provide energy.
  • Honey and other products from living systems can also become useful resources.

3. Categories of Natural Resources

Categorisation helps us group resources according to shared characteristics and communicate about them more clearly.

3.1 Resources Essential for Life

  • Air: necessary for breathing and life processes.
  • Water: essential for drinking and many biological and human activities.
  • Food: obtained through cultivation of soil and from other living organisms.
  • Humans cannot manufacture these basic natural systems in the same way that we manufacture ordinary products.

3.2 Resources for Materials

Humans transform natural materials into useful or beautiful objects. For example, wood can be made into furniture or carved into a decorative object. India's geographical diversity provides many natural materials such as wood, marble, coal and gold.

3.3 Resources for Energy

Energy is central to modern life, transportation and production. Natural sources include coal, water, petroleum, natural gas, sunlight and wind.

Life

Air • Water • Food

Materials

Wood • Marble • Metal ores • Minerals

Energy

Coal • Petroleum • Natural gas • Sunlight • Wind • Flowing water

4. Renewable and Non-Renewable Resources

Restoration and Regeneration

The chapter explains that Nature works through cycles of restoration and regeneration. Restoration means returning something to a healthy state after damage. Regeneration refers to Nature's ability to create new life and conditions that support life.

Example: Forest cycle

A fallen tree can decompose through the activity of bacteria, fungi and insects. Its materials return to the soil, helping new plants grow. This illustrates Nature's cycles of regeneration.

4.1 Renewable Resources

Renewable resources can be replenished through natural processes over time, provided their natural rate of restoration and regeneration is not disturbed.

Renewable resourceWhy renewable?Important condition
Solar energySunlight is continuously available through natural processes.Use it sustainably and develop suitable technology.
Wind energyWind is naturally renewed.Responsible use and suitable infrastructure.
Flowing waterRivers are replenished through rainfall and, in some regions, melting glaciers.Water cycles must not be seriously disrupted.
Forests / timberForests can regenerate.Harvesting must not exceed regeneration.
SoilSoil can replenish through natural processes.Prevent degradation and excessive erosion.
Important: “Renewable” does not mean “unlimited”. If a resource is used faster than Nature can restore it, it can become depleted.

4.2 Non-Renewable Resources

Non-renewable resources form over very long periods and cannot be replenished at the rate at which humans use them.

  • Fossil fuels: coal and petroleum.
  • Minerals and metals: iron, copper and gold.
  • Because formation takes very long periods, they need judicious use.
  • The chapter uses India's coal reserves to illustrate the need for careful use while more sustainable alternatives are developed.

5. Distribution of Natural Resources and Its Implications

Natural resources are not evenly distributed across the world or even within individual countries. This uneven distribution affects where people live, where industries develop, how trade occurs and how regions interact.

Effects of uneven distribution

  • Human settlements: people and towns may grow around resource-rich areas.
  • Industries: industries may locate near sources of raw materials or energy.
  • Employment: resource-based industries can create local jobs.
  • Trade: resources can become important commodities in regional and international trade.
  • International relations: countries may have strategic interests in resource-rich regions.
  • Conflicts: competition for resources can contribute to tensions and conflicts.
  • Displacement: development in resource-rich regions can sometimes displace people from their homes.
  • Cultural impacts: sacred places and culturally important landscapes may come under pressure.

Shared natural resources

Nature does not follow political boundaries. Rivers and other resources may cross state or national borders, requiring cooperation and management.

Kaveri River example

The chapter uses the sharing of Kaveri river water among Karnataka, Tamil Nadu, Kerala and Puducherry as an example of how water-sharing can require negotiation and careful management.

Wootz steel: resources + knowledge + skills

The chapter points out that natural resources combined with human knowledge and skills can create unique products such as Wootz steel. Trade in such products contributed to the development of large empires in India.

6. The “Natural Resources Curse”

The natural resource curse, also called the paradox of plenty, refers to a situation in which having abundant natural resources does not automatically produce economic prosperity.

Why can this happen?

  • A region may have resources but lack the industries or skills needed to convert them into higher-value products.
  • Resource extraction alone may not create broad-based economic development.
  • Weak planning or governance can prevent resources from becoming lasting benefits.
  • Resource-rich regions can experience environmental or social costs from extraction.
Natural resources+Technology+Skills+Good governance & planning→Long-term benefits

The chapter notes that India has generally avoided this curse by investing in industries that process resources to meet growing needs, while also emphasising that balancing extraction with sustainability remains a challenge.

7. Responsible and Wise Use: Stewardship

Stewardship means treating natural resources as something that humans have a responsibility to manage carefully, with attention to restoration, regeneration and sustainability.

For renewable resources

  • Use them at a rate that allows natural regeneration.
  • Restore degraded ecosystems.
  • Reduce wasteful consumption.
  • Reuse and recycle water and materials wherever possible.
  • Protect biodiversity and ecological cycles.

For non-renewable resources

  • Use them judiciously.
  • Reduce unnecessary consumption.
  • Improve efficiency.
  • Develop and adopt more sustainable alternatives.

Consequences of irresponsible use

  • Pollution
  • Biodiversity loss
  • Climate-related environmental changes
  • Groundwater depletion
  • Soil degradation
  • Loss of ecosystem functions

8. Groundwater: Over-exploitation Caselet from Punjab

The chapter presents Punjab as a case study of how intensive resource use can create long-term sustainability problems.

What happened?

  • During the Green Revolution period, farmers shifted toward high-yielding varieties of wheat and paddy.
  • These crops required substantial water, increasing groundwater extraction.
  • Availability of free electricity contributed to extensive pumping.
  • Modern farming also involved chemical fertilisers and pesticides.
  • Groundwater levels declined substantially in large parts of the state.
  • The chapter notes that a large share of Punjab's area has been classified as over-exploited, meaning extraction exceeds the rate of natural replenishment.
  • Chemicals from fertilisers and pesticides can also enter groundwater and create health hazards.
High water-demand crops+Intensive pumping+Favourable electricity supply→Groundwater depletion

Possible responses

  • Rainwater harvesting.
  • Rejuvenation of ponds and tanks.
  • Reducing wasteful water consumption.
  • Processing and reusing water.
  • Using agricultural practices that reduce pressure on water resources.

9. The Case of Cement

Cement is essential for houses, schools, hospitals, roads, bridges and other infrastructure, but its production can create significant environmental impacts.

Concerns

  • Cement production releases fine dust.
  • Dust can affect human and animal lungs.
  • Dust settling on leaves can reduce plant productivity.
  • Production can contribute to soil and water pollution.

Ways discussed in the chapter

  • Pollution-control guidelines for cement factories.
  • Development of alternative materials that can reduce pollution.
  • Use of traditional materials such as stone and mud in suitable construction.
  • Use of plant-based materials and recycled materials.
  • Combining traditional knowledge with modern technology to create more sustainable construction methods.
Key idea: The goal is not simply to stop using useful materials, but to improve how resources are extracted, processed, used and replaced.

10. Vṛikṣhāyurveda: Traditional Knowledge and Sustainable Practice

Vṛikṣhāyurveda is described in the chapter as an ancient Indian botanical knowledge system concerned with the study and care of plants and trees. The term combines vṛikṣha (tree) and ayurveda (science of life/health).

Practices discussed

  • Choosing plants suited to different soil types.
  • Seed collection and preservation.
  • Pre-planting treatment of seeds.
  • Irrigation according to plant species, growth stage and season.
  • Natural approaches to pest management.
  • Growing suitable plants together.
  • Crop rotation and mixed cropping to support soil health.
  • Ploughing methods that retain soil moisture and support soil organisms such as fungi, bacteria and earthworms.
Traditional knowledge+Modern science→Resource-efficient practices→Sustainability

11. Caselet: Organic Farming in Sikkim

The chapter uses a family farm in Sikkim to illustrate the transition from chemical-intensive farming toward organic practices.

Transition described

  • The farm faced declining yields and increasing costs from chemical inputs.
  • When the state promoted organic farming, the family shifted its practices.
  • The transition was difficult at first because yields initially declined while soil recovered.
  • The family adopted compost, natural pest repellents made with neem and garlic, and multiple crops.
  • After several years, the farm recovered and produced crops such as cardamom, ginger and traditional vegetables.
  • The chapter states that Sikkim became a 100% organic state in 2016.
  • The caselet connects organic farming with biodiversity, tourism and farmer incomes.

12. Renewable Energy and the International Solar Alliance

Why move towards renewables?

Because non-renewable resources are finite, the chapter emphasises the need to shift toward renewable sources of energy wherever possible.

International Solar Alliance

  • The chapter describes an international initiative launched by India and France in 2015.
  • It focuses on cooperation among sunshine-rich countries to harness solar energy.
  • The initiative includes sharing technical knowledge and supporting affordable financing for solar projects.

Bhadla Solar Park

The chapter highlights the Bhadla Solar Park in Rajasthan as an example of India's solar-energy development.

Equity in resource access

Resource management also has a social dimension. Access to basic resources such as clean water and clean air can be unequal. Some urban areas may lack adequate regular drinking-water supply, while pollution can affect people who have fewer ways to protect themselves.
