1.1 What is a Resource?
A 'resource' is any substance, object, or attribute that satisfies a human need and has utility. A thing becomes a resource only when technology, time, and knowledge are applied to it. For example, crude oil was useless until humans learned to refine it into fuel. Resources form the foundation of economic activity — without them, production, trade, and development are impossible.
Characteristics of Resources
- Utility: The resource must satisfy a want or need.
- Accessibility: Humans must be able to obtain and use it.
- Technological feasibility: Suitable technology must exist.
- Economic viability: The cost of extraction must be less than the value derived.
1.2 Classification of Resources
Resources are classified on four bases — origin, exhaustibility, ownership, and stage of development.
A) On the Basis of Origin
| Type | Definition | Examples |
|---|---|---|
| Biotic | Obtained from the biosphere — living or once-living | Forests, animals, fish, fossil fuels, agricultural crops |
| Abiotic | Non-living, physical things | Rocks, minerals, water, air, sunlight, metals |
B) On the Basis of Exhaustibility
| Type | Definition | Examples | AP-Specific Example |
|---|---|---|---|
| Renewable | Can be replenished through natural cycles | Solar energy, wind, water, forests | Solar potential in Anantapur, wind farms in Kurnool |
| Non-renewable | Finite, take millions of years to form | Coal, petroleum, natural gas, minerals | Godavari coal, Mangampeta barytes |
C) On the Basis of Ownership
| Type | Owned by | Examples |
|---|---|---|
| Individual | Private persons | Farmland, house, private pond |
| Community | Entire community | Village pastures, community forests, public parks |
| National | The nation (government) | Minerals, forests, wildlife, water bodies |
| International | All nations collectively | Ocean resources beyond 200 nautical miles (EEZ) |
D) On the Basis of Stage of Development
| Type | Meaning |
|---|---|
| Potential | Currently unused but available for future use |
| Developed | Already surveyed and being used |
| Stock | Known to exist but no technology to utilise |
| Reserves | Part of stock that can be used in the future |
1.3 Human, Natural, and Human-Made Resources
Natural resources come directly from nature — air, water, soil, minerals, forests. Human-made resources are created by applying knowledge and skill — buildings, bridges, machines, roads. Human resources refer to the population in terms of its size, skills, education, and abilities. People are the most important resource because they transform natural resources into usable goods.
'Human resources are the ultimate resource. It is people who turn a piece of land into a farm and a lump of iron into a machine.'
Human Capital vs Human Resources
Human resources become 'human capital' when investment is made in education, health, and training. A healthy and educated population contributes more to economic growth. AP's literacy rate of about 67% (as per recent data) shows room for improvement in converting its large population into high-quality human capital.
1.4 Sustainable Development
The Problem of Resource Depletion
Industrialisation, population growth, and consumerism have led to over-exploitation of resources. If every person on Earth lived like an average American, we would need five planets' worth of resources. This is simply unsustainable.
Definition
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This definition comes from the Brundtland Commission Report (1987), titled 'Our Common Future'.
Principles of Sustainable Development
- Respect and care for all forms of life.
- Improve the quality of human life.
- Conserve the Earth's vitality and diversity.
- Minimise the depletion of non-renewable resources.
- Change personal attitudes and practices towards the environment.
AP Context: Sustainable Initiatives
Andhra Pradesh has taken several steps toward sustainable development:
- Solar power: AP is one of India's top states in installed solar capacity, with large parks in Anantapur and Kurnool.
- Wind energy: The state ranks among the top five in wind power generation.
- Watershed management: Programs in drought-prone Rayalaseema districts.
- Fisheries: Sustainable aquaculture practices in the Godavari-Krishna delta region.
1.5 Conservation of Resources
Conservation means using resources carefully and giving them time to get renewed. It involves both judicious use and preservation.
Methods of Conservation
- Reduce, Reuse, Recycle (3Rs): Cut consumption, reuse items wherever possible, and recycle waste materials.
- Afforestation: Planting trees to restore forest cover.
- Water conservation: Rainwater harvesting, watershed management.
- Energy efficiency: Using LED lights, energy-efficient appliances.
- Legislation: Laws like the Wildlife Protection Act (1972), Forest Conservation Act (1980).
Why Conservation Matters for AP
AP is endowed with significant mineral wealth — it holds India's largest reserves of barytes (Mangampeta in YSR Kadapa district), substantial bauxite deposits (Eastern Ghats in Visakhapatnam), and limestone (Nallamala hills, Guntur and Kurnool districts). These resources generate revenue but must be extracted carefully to avoid environmental degradation.
- Barytes (Mangampeta): One of the world's largest deposits; used in oil drilling, paints, and medical applications.
- Bauxite (Eastern Ghats): Used for aluminium production; mining faces opposition from tribal communities due to displacement concerns.
- Limestone: Used in cement factories; many plants operate in Guntur and Kurnool districts.
- Forests: AP has about 23% forest cover; Eastern Ghats forests support diverse wildlife and tribal livelihoods.
1.6 Common Mistakes and How to Fix Them
| Common Mistake | Why It's Wrong | Fix |
|---|---|---|
| Saying petroleum is renewable | Petroleum takes millions of years to form | It is non-renewable, specifically a fossil fuel |
| Confusing potential and developed resources | Potential = unused; developed = in use | Think: potential is 'waiting', developed is 'working' |
| Calling all minerals 'metallic' | Minerals can be metallic (iron) or non-metallic (mica) | Check if the mineral contains metal |
| Forgetting human resources in the list | People are the most important resource! | Always list human resources separately as the 'ultimate resource' |
1.7 AP Board Exam Focus
Marks Distribution (Based on Previous Papers)

1.8 Quick Self-Test
Q1. Which of these is a non-renewable resource? (a) Solar energy (b) Coal (c) Wind (d) Water A1. (b) Coal
Q2. Mangampeta in YSR Kadapa district is famous for which mineral? A2. Barytes — one of the world's largest deposits.
Q3. What does 'sustainable development' mean? A3. Meeting present needs without compromising future generations' ability to meet theirs.
Q4. Give two examples of human-made resources. A4. Buildings and machines (also acceptable: bridges, roads, tools).
Q5. Name the three categories under which resources are classified on the basis of origin. A5. Biotic and abiotic.
