1. Introduction
- Resources are everything available in the environment that can satisfy human needs.
- They must be technologically accessible, economically feasible, and culturally acceptable.
- Examples: Land, water, soil, minerals, forests.
2. Classification of Resources
- On the basis of Origin: Biotic, Abiotic
- On the basis of Exhaustibility: Renewable, Non-renewable
- On the basis of Ownership: Individual, Community, National, International
- On the basis of Status: Potential, Developed, Stock, Reserves
| Type | Meaning | Example |
|---|---|---|
| Biotic | Living resources | Plants, animals |
| Abiotic | Non-living resources | Minerals, water |
| Renewable | Can be replenished | Solar, wind |
| Non-renewable | Limited resources | Coal, petroleum |
3. Development of Resources
- Overuse of resources leads to depletion.
- Unequal distribution creates rich and poor divide.
- Environmental problems like global warming and pollution occur.
- Need for resource planning and conservation.
4. Sustainable Development
- Development that meets present needs without harming future generations.
- Focus on conservation and balanced use.
- Important for long-term environmental stability.
5. Resource Planning in India
- Identification and inventory of resources.
- Planning structure with technology and skills.
- Matching resource development with national plans.
6. Land Resources
- India has plains (43%), mountains (30%), plateaus (27%).
- Land is used for agriculture, forests, industries, and settlements.
Land Utilisation Chart
- Forests
- Barren land
- Fallow land
- Net sown area
- Land for non-agriculture uses
7. Land Degradation & Conservation
- Causes: Deforestation, overgrazing, mining, industrial waste.
- Methods:
- Afforestation
- Controlled grazing
- Terrace farming
- Proper irrigation
8. Soil as a Resource
Types of Soil
| Soil Type | Region | Features |
|---|---|---|
| Alluvial | Northern Plains | Fertile, good for crops |
| Black | Deccan Plateau | Ideal for cotton |
| Red | Southern India | Less fertile |
| Laterite | High rainfall areas | Leached soil |
| Arid | Desert areas | Sandy, low fertility |
9. Soil Erosion & Conservation
- Types: Gully erosion, Sheet erosion
- Methods:
- Contour ploughing
- Strip cropping
- Shelter belts
10. Map Work (Very Important for Exam)
Learn to locate the following on India Map:
- Alluvial Soil – Northern Plains
