## Chapter 1: Resources and Development

### Key Concepts
- **Resource**: anything with utility and value; Natural, Human-made, Human
- **Types**: Renewable vs Non-renewable; Individual vs Community vs National vs International
- **Resource Planning**: identification → inventory → planning → conservation
- **Land Use Pattern in India**: 43% net sown area, 23% forest, rest barren/waste/pasture
- **Soil Types in India**:
