Chapter-wise Weightage

Chapter 1: Resources and Development

Chapter Overview

This chapter introduces the concept of resources, their types, and the importance of sustainable development. It covers land resources, soil types in India, and soil conservation methods.

What is a Resource?

Everything available in our environment which can be used to satisfy our needs, provided it is technologically accessible, economically feasible, and culturally acceptable is called a resource.

Classification of Resources

1. On the Basis of Origin

2. On the Basis of Exhaustibility

3. On the Basis of Ownership

4. On the Basis of Status of Development

• Potential Resources: Found but not yet utilized (e.g., Rajasthan and Gujarat have huge potential for solar and wind energy)
• Developed Resources: Surveyed, quantity and quality determined, currently in use
• Stock: Available but we lack technology to use (e.g., hydrogen from water)
• Reserves: Subset of stock, can be used with existing technology but not started yet

Resource Planning in India

Resource Planning is essential for sustainable existence. It involves:

1. Identification and inventory of resources across regions
2. Evolving a planning structure with appropriate technology, skill, and institutional setup
3. Matching resource development plans with national development plans

Land Resources

Land Use Pattern in India:

Soil Types in India

Soil Erosion and Conservation

Causes of Soil Erosion:

• Deforestation
• Overgrazing
• Mining
• Faulty farming practices

• Sheet Erosion: Top layer of soil removed over large areas by water

Soil Conservation Methods:

• Contour Ploughing: Ploughing along contour lines on slopes
• Terrace Farming: Steps cut on slopes to reduce water flow (Western & Central Himalayas)
• Strip Cropping: Alternate strips of grass between crops
• Shelter Belts: Rows of trees to break wind force
