Resources

Definition

Anything that can be used to satisfy a need is a resource.

What makes a thing Resource

Utility or usability is what makes an object or substance a resource. Example includes Water, textbook etc.
Some resources have economic value while some do not. Example: Metals may have an economic value, a beautiful landscape may not. But both satisfy human needs so these are considered as resource.
Some resources can become economically valuable with time. Example: Grandmother’s home remedies are not economically valuable today. But if they are patented and sold by a medical firm tomorrow, they could become economically valuable.

Important factors that can change substances into resources:

Time
Technology

People themselves are the most important resource. Their ideas, knowledge, inventions and discoveries that lead to the creation of more resources.
Each invention leads to many others . Example: The discovery of fire led to the practice of cooking and other processes while the invention of the wheel ultimately resulted in development of newer modes of transport.

Types of Resources

There Are 3 types Of Resources

→ Natural

→ Human made

→ Human

Natural Resource

Resources that are drawn from Nature and used without much modification are called natural resources . For example: air, water, soil, minerals etc.

Human Made Resource

The resources which are created from natural resources through human resources are known as human made resources . For example: buildings, bridges, roads etc.

Human Resource

People are human resources . It refers to the quantity and abilities of the people.

Natural Resources:

Many of natural resources are free gifts of nature.
These can be used directly but in some cases we have to use tools and technology may be needed to use a natural resource to utilize it in best possible way.
Natural resources are classified into different groups depending upon their level of development and use;

→ Origin

→ Stock

→ distribution

On the basis of their development and use resources it can be classified into two groups:

Actual resources : Those resources whose quantity is known. These resources are being used in the present. For Example: The dark soils of the Deccan plateau in Maharashtra

Potential resources : Those whose entire quantity may not be known and these are not being used at present. This is due to the present level of technology is not advanced enough to easily utilise these resources. For Example: The uranium found in Ladakh is a potential resource that could be used in the future.

Based on their origin it can be classified into two groups

Abiotic resources : Non-living resources. Example includes Soil, Water, rocks etc.

Biotic resources : Living resources. Example includes Plants and animals.

On the basis of Stock:

Renewable resources : Those which get renewed or replenished quickly. For example solar energy, soil, forest etc.

Some of these are unlimited and are not affected by human activities such as solar or wind energy while careless use of certain renewable resources like water, soil and forest can affect their stock.

Non-renewable resources : Those which have a limited stock. For example: Coal, Petroleum etc.

Once the stocks are exhausted it may take thousands of years to be renewed or replenished. Therefore, they are considered as non-renewable.

On the basis of their distribution resources:

Ubiquitous : Resources that are found everywhere like the air we breathe, are ubiquitous. For Example: air, water etc.

Localised : Resources that are found in only certain places are localised. For Example: Copper, Iron Ore etc.

The distribution of resources is unequal over earth and depends upon number of physical factors like terrain, climate and altitude.

Human Made Resources

Natural substances become resources only when their original form has been changed. For Example: Iron ore was not a resource until people learnt to extract iron from it.
Technology is also a human made resource.

Human Resources

People use the nature in the best possible way using their knowledge, skill and the technology. Therefore, they considered as human resources.
Education and health help in making people a valuable resource.
Improving the quality of people’s skills so that they are able to create more resources is known as human resource development.

Conserving Resources

Using resources carefully and giving them time to get renewed is called resource conservation .
Sustainable development is the development meets the needs of present and also conserve them for the future.

Principles of Sustainable development:

→ Respect and care for all forms of life

→ Improve the quality of human life

→ Conserve the earth’s vitality and diversity

→ Minimise the depletion of natural resources

→ Change personal attitude and practices toward the environment

→ Enable communities to care for their own environment.

It is our duty to ensure that:

→ All uses of renewable resources are sustainable

→ The diversity of life on the earth is conserved

→ The damage to natural environmental system is minimised.
