The phases of resource planning are:
• Identification and inventory of resources across various regions of the country. It involves surveying, mapping, qualitative and quantitative estimation and measurement of the resources.
• Evolving a planning structure, endowed with appropriate technological skill and institutional set up for implementing resource development plans.
• Matching the resource development with overall national development plans.

Answer

Anything which can be used to satisfy our needs, is technologically accessible, economically feasible and culturally acceptable can be termed as ‘Resource’.
The resources can be classified into various categories:
• On the basis of origin – biotic and abiotic
• On the basis of exhaustibility – renewable and non-renewable
• On the basis of ownership – individual, community, national and international
• On the basis of status of development – potential, developed stock and reserves.

3. Describe any three steps that can be taken to solve the problem of land degradation?

Answer

• These soils range from red to brown in colour.
• These soils are generally sandy in texture and saline in nature.
• The lower horizons of the soil are occupied by Kankar because of the increasing calcium content downwards.

5. Describe the type of resources classified on the basis of exhaustibility.

Answer

The resources on the basis of exhaustibility are classified into two categories:
• Renewable Resources: The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as renewable or replenishable resources. For example, solar and wind energy, water, forests and wildlife, etc.
• Non-Renewable Resources: These resources take millions of years in their formation. Minerals and fossil fuels are examples of such resources. Some of the resources like metals are recyclable and some like fossil fuels cannot be recycled and get exhausted with their use.

6. Describe the steps to control soil erosion in hilly areas?

Answer

The soil erosion in hilly areas can be controlled by:
• Contour ploughing: Ploughing along the contour lines can decelerate the flow of water down the slopes.
• Terrace cultivation: Steps can be cut out on the slopes making terraces which restricts erosion.
• Strip cropping: Large fields are divided into strips and strips of grass are left to grow between the crops.

7. Why is resource planning essential?

Answer

It is essential to have resource planning because:
• Resources are limited in supply.
• Resources are unevenly distributed over the surface of the earth.
• Exploitation and over utilisation of resources must be checked.

• Relief, parent rock or bed rock, climate, vegetation and other forms of life and time are important factors in the formation of soil.
• Various forces of nature such as change in temperature, actions of running water, wind and glaciers, activities of decomposers etc. contribute to the formation of soil.
• Chemical and organic changes which take place in the soil are equally important.

2. Explain the classification of resources on the basis of ownership.
