Natural resources

Natural resources are substances, materials, or components obtained from nature that support human survival, economic development, and technological progress. They are the foundation of life, essential for food, energy, raw materials, and ecological balance.

Need for classification of natural resources

Classifying natural resources helps to:

• Understand their availability and distribution
• Ensure sustainable and planned usage
• Prevent over-exploitation
• Support economic & developmental planning
• Promote conservation and environmental protection

Classification based on origin

Biotic Resources: Resources derived from living organisms. They contain organic matter (carbon compounds).

Examples

• Forests → wood, resin, latex
• Wildlife → leather, wool, meat
• Fisheries
• Agricultural crops → wheat, rice, sugarcane
• Microorganisms → fungi, bacteria, yeast

Abiotic Resources: Resources obtained from non-living components of nature. Examples: Water, Soil, Air, Minerals & metals, Sunlight, Rocks

Classification based on renewability

• Renewable Resources: Resources that replenish naturally through ecological cycles. Examples: Solar energy, Wind energy, Water, Forests, Wildlife, Soil
• Non-Renewable Resources: Resources that cannot regenerate within a human lifespan. Formed over millions of years. Examples: Fossil fuels → coal, petroleum, natural gas, Minerals → iron, copper, gold, Nuclear fuels → uranium

Classification based on development stage

• Potential Resources: Resources available but not yet fully utilized due to lack of technology, investment, or awareness.

Examples

• Tidal energy (India’s long coastline)
• Solar energy in Thar Desert
• Wind energy in coastal regions
• Geothermal energy in Himalayas

Actual Resources: Resources identified, surveyed, developed, and currently used.

Examples

• Coal in Jharia (Jharkhand)
• Petroleum in Assam
• Iron ore in Odisha
• Natural gas in Krishna-Godavari Basin

Classification based on distribution

• Ubiquitous Resources: Resources found everywhere. Examples: Air, Sunlight, Water vapour
• Localized Resources: Found only in specific geographical locations. Examples: Diamonds in Africa, Coal in Jharkhand, Petroleum in Middle East, Gold in Kolar (Karnataka)

Classification based on ownership

• Individual Resources: Owned personally by individuals. Examples: House, Private land, Vehicles, Farms
• Community Resources: Used and shared by a community. Examples: Village ponds, Community wells, Grazing lands, Public parks
• National Resources: Owned by the government of a country. Examples: Rivers, Roads and Railways, Forests, Minerals within national boundaries, Public sector property
• International Resources: Not owned by any one nation; regulated by international bodies. Examples: Oceans beyond 200 nautical miles (beyond EEZ), Antarctica, Outer space

Classification based on exhaustibility

• Inexhaustible Resources: Naturally unlimited and not depleted by use. Examples: Solar radiation, Air, Wind energy, Tides
• Exhaustible Resources: Available in limited quantity; can be used up. Examples: Minerals, Fossil fuels, Fertile soil, Forests (if overexploited)
