જવાબ : Resource planning is proper and judicious planning of resources.
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.
 

જવાબ : 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.
 

જવાબ : Three steps that can be taken to solve the problem of land degradation:
• Afforestation and proper management of grazing.

જવાબ : Three characteristics of Arid soils in India are:
(i) These soils range from red to brown in colour.
(ii) These soils are generally sandy in texture and saline in nature.
(iii) The lower horizons of the soil are occupied by Kankar because of the increasing calcium content downwards.
 

જવાબ : 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.
 

જવાબ : 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.
 

જવાબ : 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.

જવાબ : The uppermost layer of earth is called soil. It is the most important renewable natural resource. It is the medium of plant growth and supports different types of living organisms on the earth.
The four main factors which help in the formation of soil are:
• 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.

જવાબ : Classification of resources on the basis of ownership:
• Individual Resources: Resources which are owned privately by individuals such as plots, houses, plantation, pasture lands, ponds etc.
• Community Owned Resources: Resources which are accessible to all the members of the community such as grazing grounds, burial grounds, village ponds etc.
• National Resources: All the resources within the political boundaries and oceanic area upto 12 nautical miles (22.2 km) from the coast termed as territorial water and resources therein belong to the nation.
• International Resources: The oceanic resources beyond 200 nautical miles of the Exclusive Economic Zone belong to open ocean and no individual country can utilise these without the concurrence of international institutions.

જવાબ : Everything available in our environment which can be used to satisfy our needs, is called a resource. It should be technologically accessible, economically feasible and culturally acceptable. Only then, it can be termed as a ‘Resource’. Examples are: minerals, forests, fossil fuels etc..

જવાબ : There are regions which are rich or self-sufficient in certain types of resources and there are areas that are deficient or have acute shortage of some vital resources.
For example:

1. The states of Jharkhand, Chhattisgarh and Madhya Pradesh are rich in minerals and coal deposits.
2. Arunachal Pradesh has abundance of water resources but lacks in infrastructural development.
3. Rajasthan is very well endowed with solar and wind energy but lacks in water resources.
4. The cold desert area of Ladakh has very rich cultural heritage. It is deficient in water, infrastructure and some vital minerals.
   Such cases call for balanced resource planning at different levels.

જવાબ : Importance of resources for man:

1. Resources are vital for human survival.
2. They are important for maintaining the quality of life as man has been using the bio-physical environment to satisfy his needs.
3. Natural resources form the backbone of the economy of a nation.
4. These are the bases for economic strength and prosperity of the people.
5. They provide material, energy and favourable conditions for development.

જવાબ : Stock. Materials in the environment, which have the potential to satisfy human needs but man does not have the appropriate technology to access them are included among stock, e.g. water is a compound of two inflammable gases: hydrogen and oxygen, which can be used as a rich Source of energy. But we do not have the required technical know-how to use them for this purpose. Reserves. Reserves are the subset of the stock, which can be put into use with the help of existing technical ‘know-how’ but their full use has been postponed for meeting the future needs, e.g., forest reserves, iron-ore reserves, water in the dams etc.

જવાબ : Potential Resources. Resources which are found in a region, but have not been utilised, e.g.r Gujarat and Rajasthan have a lot of potential for the development of wind and solar energy, but so far they have not been developed fully.
Developed Resources. Resources which are surveyed and their quality and quantity have been determined for utilisation. The development of resources depends on technology and level of their feasibility, e.g., water resources used for hydel power generation or irrigation purposes.

જવાબ : On the basis of ownership, there are four types of resources:

1. Individual Resources. Resources, which are owned privately by individuals, e.g., farmers own
   pieces of land or houses. Plantation, pasture lands, water in wells are some resources owned by individuals.
2. Community Owned Resources. These resources are accessible to all the members of the community, e.g., village ponds, public parks, playgrounds in urban areas are accessible to all the residents of that area.
3. National Resources. All the resources within the political boundary of a nation including the territorial water (oceanic area upto 12 nautical miles from the coast) extending into the ocean and resources therein belong to the nation, e.g., all minerals, forests, wildlife, water resources, land etc.
4. International Resources. There are international institutions which own and regulate some resources, e.g., The oceanic resources beyond 200 km of the Exclusive Economic Zone belong to the open ocean and no individual country can utilise these without the concurrence of international institutions.

જવાબ : Two characteristics of non-renewable resources:

1. They cannot be recycled and get exhausted with their use.
2. They take millions of years in their formation.

1. Recyclable resources, e.g., metals.
2. Non-recyclable resources, e.g., fossil fuels.

જવાબ : On the basis of exhaustibility, resources can be classified as: Renewable and Non-renewable.

જવાબ : On the basis of origin, resources can be classified as Biotic and Abiotic.
Biotic Resources are obtained from the biosphere. They have life or are living resources, e.g., human beings, fisheries, forests, etc.
Abiotic Resources include all non-living things, e.g., rocks and minerals.

જવાબ : Resources can be classified in the following four ways:
(a) On the basis of Origin:

• Biotic
• Abiotic

• Renewable
• Non-renewable

• Individual (Personal)
• Community
• National
• International

• Potential
• Developed
• Reserve
• Stock

જવાબ : Mere presence of resources, as free gifts of nature, does not make them resources. Human beings are essential components of resources because they transform material available in our environment into resources. The utility of resources depends on the stage of cultural development of man and the tools and technology used by him.
