📝 Note on Chapter Numbering
In the NCERT Geography textbook, this is "Chapter 1: Resources". However, in our SST sequence, it is listed as Chapter 10.

📖 PART 1: What is a Resource?

Anything that can be used to satisfy a human need is a Resource. For example, the water you drink, the electricity in your house, the textbook you use, and the vehicle you travel in.

🌿 PART 2: Types of Resources

Types of Resources

Resources are generally classified into three types: Natural, Human-made, and Human.

1. Natural Resources

Resources that are drawn from Nature and used without much modification are called Natural Resources. The air we breathe, the water in our rivers, soils, minerals are all natural resources.

Natural resources are broadly grouped into two categories based on their availability:

Type Definition Examples
Renewable Resources Those which get renewed or replenished quickly. Some are limitless and not affected by human activities. However, careless use of certain renewable resources like water, soil and forest can affect their stock. Solar energy, wind energy. (Water seems unlimited but shortages and drying up is a major problem).
Non-Renewable Resources Those which have a limited stock. Once the stocks are exhausted it may take thousands of years to be renewed or replenished. Since this period is much more than human life spans, they are considered non-renewable. Coal, petroleum, natural gas, iron ore, copper.

The distribution of natural resources depends on physical factors like terrain, climate, and altitude. The distribution is unequal because these factors differ so much over the Earth.

2. Human-Made Resources

3. Human Resources

Human Resource refers to the number (quantity) and abilities (mental and physical) of the people.

♻️ PART 3: Conserving Resources

Sustainable Development

Using resources carefully and giving them time to get renewed is called Resource Conservation.
Balancing the need to use resources and also conserving them for the future is called Sustainable Development.

How to Conserve Resources

Principles of Sustainable Development

It is our duty to ensure that:

  1. All uses of renewable resources are sustainable.
  2. The diversity of life on the earth is conserved.
  3. The damage to natural environmental system is minimised.
  4. Respect and care for all forms of life.
  5. Improve the quality of human life.
  6. Conserve the earth’s vitality and diversity.
  7. Enable communities to care for their own environment.
