Chapter 1: Natural Resources and Their Use
NCERT-aligned • Detailed explanations • Maps/diagrams • Competency practice
What makes something a natural resource?
Nature includes living and non-living components of the environment. A part of nature becomes a resource when people recognise its usefulness and have the knowledge, skills and technology to use it. Water, forests, soil, minerals, sunlight and wind can therefore support human life and economic activity.
🔎 Think & Explore
Identify one piece of evidence a historian or geographer could use to investigate this idea. Explain what the evidence can and cannot tell us.
🧭 Skill Builder
Use a map, timeline, table or short source extract to identify patterns. Separate the evidence from your interpretation.
Renewable and non-renewable resources
Renewable resources can regenerate naturally when their use remains within the rate of renewal. Solar energy, wind and flowing water are examples. Forests and groundwater can also be renewable, but only when extraction does not exceed natural replenishment. Coal and petroleum are non-renewable on a human timescale.

Distribution is uneven
Natural resources are not distributed equally across India or the world. Differences in geology, climate, relief and water availability influence where resources occur. Uneven distribution affects settlements, agriculture, industries, trade and sometimes competition over resources.

Sustainable use
A resource can become scarce when people use it faster than nature can restore it. Sustainable use means meeting present needs while maintaining the ability of natural systems to regenerate and support future generations.

Traditional knowledge and conservation
Communities have developed practices that regulate the use of forests, water, grazing areas and fisheries. Such practices can help maintain ecological balance when they respect natural cycles and limits.

Nature → Usefulness recognised → Human knowledge/technology → Resource
↓
Rate of use ≤ regeneration → more sustainable use
Rate of use > regeneration → depletion / scarcity
📊 Key Comparison
| Concept | Core idea | Example |
|---|---|---|
| Renewable | Can regenerate under suitable conditions | Solar energy, wind |
| Conditionally renewable | Can regenerate if use stays within natural limits | Forests, groundwater |
| Non-renewable | Forms too slowly for human-scale replacement | Coal, petroleum |

📌 Case-Based Question
A district depends heavily on groundwater for farming. Over several years, extraction rises while recharge remains limited.
- What is the central issue or pattern?
- Identify two pieces of evidence that should be examined.
- Explain one cause-and-effect relationship.
- What additional source could strengthen the investigation?
🔥 HOTS / Competition Corner
- Explain why a single map or source cannot always provide a complete historical picture.
- Compare two factors and decide which evidence would be needed to establish their relationship.
- Design a small local survey or map-based investigation related to the chapter.
- Write a short evidence-based explanation rather than a memorised paragraph.
✍️ Exam Practice
- Explain the main concepts of the chapter with a suitable diagram/map.
- Differentiate two related terms.
- Explain one cause-and-effect relationship.
- Describe one important historical/geographical example.
- Answer a case-based question using evidence.
