Resources and Development Class 10 Notes

1. Introduction to Resources

• Definition: Resources are everything available in the environment that can be used to satisfy human needs.
• Types of Resources:
• Natural Resources: Derived from nature (e.g., air, water, soil, minerals).
• Human-Made Resources: Created by humans using natural resources (e.g., buildings, machinery).
• Human Resources: People who use their skills and knowledge to create more resources.

2. Classification of Resources

• Based on Origin:
• Biotic Resources: Obtained from living things (e.g., forests, animals).
• Abiotic Resources: Obtained from non-living things (e.g., minerals, rocks).
• Based on Exhaustibility:
• Renewable Resources: Can be replenished (e.g., solar energy, wind energy).
• Non-Renewable Resources: Limited in quantity (e.g., coal, petroleum).
• Based on Ownership:
• Individual Resources: Owned by individuals (e.g., land, house).
• Community Resources: Accessible to all members of a community (e.g., parks, ponds).
• National Resources: Owned by the nation (e.g., forests, minerals).
• International Resources: Regulated by international institutions (e.g., oceanic resources).
• Based on Development Status:
• Potential Resources: Not yet utilized (e.g., solar energy in deserts).
• Developed Resources: Surveyed and utilized (e.g., coal mines).
• Stock Resources: Exist but lack technology to harness (e.g., hydrogen in water).
• Reserves: Resources that can be used in the future with available technology.

3. Development of Resources

• Sustainable Development: Using resources in a way that meets present needs without compromising future generations.
• Importance of Planning:
• Ensures equitable distribution of resources.
• Prevents overexploitation and environmental degradation.
• Gandhiji’s View: “There is enough for everyone’s need but not for everyone’s greed.”

4. Resource Planning in India

• Steps in Resource Planning:

1. Identification and Inventory: Surveying and mapping resources.
2. Evolving a Planning Structure: Developing technology and institutions.
3. Matching Resource Development Plans with National Development Plans.

• Challenges:
• Unequal distribution of resources.
• Lack of technology and infrastructure.
• Overexploitation and environmental degradation.

5. Land Resources

• Land Use Pattern in India:
• Forests: 22% (required 33% for ecological balance).
• Agriculture: 54%.
• Non-Agricultural Use: 4%.
• Barren and Wasteland: 6%.
• Permanent Pastures: 3%.
• Other Uses: 11%.
• Land Degradation:
• Causes: Deforestation, overgrazing, mining, industrial waste.
• Conservation Measures: Afforestation, controlled grazing, waste management.

6. Soil as a Resource

• Types of Soil in India:
• Alluvial Soil: Found in river basins, fertile, ideal for agriculture.
• Black Soil: Rich in minerals, suitable for cotton cultivation.
• Red and Yellow Soil: Found in low rainfall areas, less fertile.
• Laterite Soil: Formed by leaching, poor in nutrients.
• Arid Soil: Sandy, found in deserts.
• Forest Soil: Rich in organic matter, found in hilly areas.
• Soil Erosion:
• Causes: Deforestation, overgrazing, improper farming practices.
• Prevention: Contour ploughing, terrace farming, afforestation.

7. Water Resources

• Importance: Essential for life, agriculture, and industries.
• Water Scarcity:
• Causes: Overuse, pollution, unequal distribution.
• Solutions: Rainwater harvesting, watershed management.
• Multi-Purpose River Projects:
• Benefits: Irrigation, electricity, flood control.
• Drawbacks: Displacement of people, environmental issues.

8. Mineral Resources

• Types:
• Metallic Minerals: Iron, copper, gold.
• Non-Metallic Minerals: Mica, limestone.
• Conservation: Recycling, using substitutes, reducing waste.

9. Energy Resources

• Conventional Sources:
• Coal: Most abundant fossil fuel in India.
• Petroleum: Used in transportation and industries.
• Natural Gas: Cleaner alternative to coal and petroleum.
• Electricity: Generated from thermal, hydro, and nuclear power.
• Non-Conventional Sources:
• Solar Energy: Abundant and renewable.
• Wind Energy: Harnessed through windmills.
• Biogas: Produced from organic waste.
• Tidal and Geothermal Energy: Emerging sources.

10. Conservation of Resources

• Why Conserve?:
• Resources are limited.
• Overexploitation leads to environmental degradation.
• Methods:
• 3 R’s: Reduce, Reuse, Recycle.
• Sustainable development.
• Afforestation and water management.

11. Sustainable Development

• Definition: Development that meets the needs of the present without compromising future generations.
• Goals:
• Economic growth.
• Environmental protection.
• Social equity.
• Examples:
• Use of renewable energy.
• Organic farming.
• Waste management.

12. Summary

• Resources are essential for human survival and development.
• Proper planning and sustainable use are necessary to prevent depletion.
• India faces challenges like unequal distribution and overexploitation.
• Conservation and sustainable development are key to ensuring resource availability for future generations.
