Social Sciences: Class 8 — Chapter 1: Natural Resources and Their Use

Introduction & The Big Questions

Concerned social scientists emphasize the need to move toward a regenerative economy—an economy that operates in harmony with nature, repurposing used resources, minimizing waste, and replenishing depleted resources.

The Big Questions:

1. When does Nature become a Resource?

Nature refers to the totality of life and non-life forms that are part of our environment but have not been created by humans. These elements become resources when humans use them for sustenance or create new things from them for consumption.

For an entity to be called a resource, it must meet three criteria:

In this context, exploitation refers to the extraction, utilisation, and consumption of natural resources.

2. Categories of Natural Resources

2.1 Categorisation by Use

  • Resources essential for life: Air, water, and soil. These are fundamental to existence and cannot be artificially manufactured.
  • Resources for materials: Natural gifts transformed by humans for utility or beauty (e.g., wood into furniture, marble, coal, gold).
  • Resources for energy: Sources that power modern living, such as coal, water, petroleum, natural gas, sunlight, and wind.

2.2 Renewable and Non-renewable Resources

This classification is based on whether resources can replenish themselves over time.

  • Renewable resources: Resources that can regenerate through natural cycles, provided their natural rhythm of restoration is not disturbed (e.g., solar energy, wind energy, flowing water, timber).
  • Non-renewable resources: Resources created over extremely long geological periods that cannot be replenished at the rate they are consumed (e.g., fossil fuels like coal and petroleum, and metals like iron, copper, and gold).

Ecosystem Functions vs. Ecosystem Services: Ecosystem functions are natural processes (e.g., a forest filtering water or preventing soil erosion). When these processes directly benefit humans, they are called ecosystem services.

3. Distribution of Natural Resources and its Implications

Natural resources are unevenly distributed across the planet. This uneven distribution shapes human settlements, trade patterns, international relations, and conflicts.

3.1 The 'Natural Resource Curse'

The natural resource curse (or paradox of plenty) is a phenomenon where regions rich in natural resources experience slower economic growth and development. This often happens because these economies fail to develop industries that convert raw resources into higher-value products.

3.2 Resource Sharing and Conflicts

Because nature does not respect political boundaries, sharing resources often leads to geopolitical tensions. An example is the sharing of the Kaveri River water among Karnataka, Tamil Nadu, Kerala, and Puducherry, which requires careful negotiation and management.

4. Responsible and Wise Use of Natural Resources: Stewardship

Sustaining life requires stewardship—respecting nature and using resources in a way that enables the restoration of renewables and the judicious use of non-renewables to prevent biodiversity loss, pollution, and climate change.

4.1 Overexploitation of Groundwater: Punjab Case Study

During the Green Revolution in the 1960s, Punjab shifted to high-yielding varieties of wheat and paddy, which required intensive watering and chemical inputs. This led to:

  • Severe depletion of groundwater, with water tables falling below 30 metres in many areas.
  • Health hazards due to pesticides and fertilizers dissolving into the remaining groundwater.
  • Nearly 80% of Punjab's area being classified as 'over-exploited'.

4.2 Traditional and Sustainable Alternatives

  • Vrikshayurveda: An ancient Indian botanical science (formalised around the 10th century CE by Surapala) focusing on plant care, soil health, crop rotation, and natural pest repellents.
  • Organic Farming in Sikkim: In 2016, Sikkim became India's first 100% organic state. By transitioning to compost and natural pest repellents (neem, garlic), local biodiversity flourished, tourism increased, and farmers' incomes rose by 20% on average.
  • Alternative Materials: Reducing the use of highly polluting materials like cement by reviving traditional materials (mud, stone) and using recycled plastics.

4.3 Renewable Energy Leadership

The International Solar Alliance (ISA), launched by India and France in 2015, is a coalition of sunshine-rich countries committed to harnessing solar power. Projects like the Bhadla Solar Park in Rajasthan exemplify this transition.

5. Summary & Philosophical Outlook

We must act as stewards of natural resources. The Bhagavad Gita refers to lokasangraha—the idea that everyone must transcend personal desires and act for the wellbeing of all.

Note: History's Darker Periods

Studying history's darker periods (such as wars, Nazism, and brutality) with "detachment and sensitivity" is essential. It allows us to understand what made such ideologies possible so we can prevent their recurrence, without blaming current generations for past actions.
