RESOURCES-Anything that can be used to satisfy a need is a resource. In other words A person, asset, material, or capital which can be used to accomplish a goal is a RESOURCE

EXAMPLE OF RESOURCES-water, electricity, vehicles, textbook etc are resources.                                                                                                                                                                                                                                                                                     What makes things become a resources ?

Things become resource only when they have some usability or utility or need.Time and Technology are the two factors which can change substance into resources.

Example-Earlier we don’t the use of wind but with the advancement of technology and time it can be used for generating electricity now it is a resources and it has been achieved because of our needs.

People are also resource-because it’s their ideas, knowledge, inventions and discoveries that lead to the creation of more resources.

                                               Types of resources
It’s of three types

1.Natural resources

Natural resources are classified into four categories

  • On the basis of level of development-Actual resources and Potential    resources
  • On the basis of origin-Biotic resources and A biotic resources.
  • On the basis of Stock-Renewable resources and Non-renewable resources
  • On the basis of Distribution-Ubiquitous resources and Localised resources

Natural Resources: Resources which are obtained from the nature and used without much alteration are called Natural resources. It’s free gift of nature  .
It can be used directly and in some cases tools and technology may be needed to use natural resources.

Natural ResourceProduct/service
TreesPaper, furniture, fuel,wood,fruits,vegetables etc
Airwind energy
Animalsfood(milk, cheese etc) and clothing (wool,silk ,leather etc)
sunlightsolar energy,photosynthesis
water-hydroelectricity generation,drinking,cleaning and other daily use
Natural gasfuel,electricity,heating

On the basis of level of development-Actual resources and Potential    resources

Actual resources-Actual resources are those that have been surveyed, their quantity and quality determined and are being used in present times.
In simple words resources whose quantity is known are called Actual resources.
Example-Rich deposit of Petroleum in west Asia .

Potential resources-Potential resources are those that exist in a region and may be used in the future. It’s entire quantity may not  be known.
 For example, petroleum may exist in many parts of India, having sedimentary rocks but until the time it is actually drilled out and put into use, it remains a  potential resource.

Why these resources are called Potential resources ?
These resources are called Potential resources because the level of technology we have at present may not be advanced enough to easily utilize these resources.

Resources which are at present potential resources may be converted into actual resources with the time ,need and development of technology.

Example-High speed wind –Earlier it was potential resources but now Actual resources.

Resources on the basis of Origin

Biotic resources-This are living and the Renewable resources .It includes Plants, Animals and Fossil fuels (coal, oil and natural gases). Fossil fuels are classified  as biotic resources because they were formed from the decay of organic matter over millions of years.

Abiotic resources-abiotic resources originate from nonliving and inorganic materials.
Examples of Abiotic resources-Air,water,Soil,rocks and minerals(gold,copper,aluminium,silver,iron etc)

On the basis of stock or Availability

Renewable resources-Resource which get renewed or replenished quickly during our life time.sunlight,water,plants,and animals.

  • Some of this are unlimited and are not affected by human activity(example-wind energy and solar energy).
  • In contrast careless use of certain renewable resources like water, soil and forest can affect their stock.
  • The rate at which this resources replenished differ.

Non-Renewable resources
Resources that have limited stock and takes thousands of years to get replenished. It takes  more  times to replenish than the life span of human that’s why it is 
called non-renewable resources.

Example-coal, petroleum and natural gas.

On the basis of Distribution

Ubiquitous resources-Resources that are accessible everywhere.

Examples of Ubiquitous resources-Air and water.

Localised resources-Resources that are accessible in only certain places.

Examples of localized resources-copper ,iron ore,and some other mineral and crops  which are found only in certain regions.

              Resources are distributed unequally on the earth
climate, topography, and altitude are the main causes for the  unequal distribution of  natural resources on the earth.

Human made resources-Resources made by human are called human made resources thus When a natural resource undergoes drastic change by human interference, it becomes human-made resource.

Examples-Iron ore is converted into by human thus it is human made resources ,other examples of human made resources are-buildings,roads,technology etc

Human resources
It refers to the quantity and physical and mental ability of people.
It is the skill of human that help in transferring the physical material into a valuable resources.
Improving the quality of people’s skill so that they are able to create more resources is known as Human Resource Development.

Conserving resources
If we are not careful towards using resources renewable even renewable resources can become very scarce and non-renewable one can definitely get exhausted.
Using resources carefully and giving them time to get renewed is called Resource conservation.

We should follow the three Rs of conservation for sustainable development.

Reduce: We should reduce consumption.
Reuse: We should reuse as many items as possible.
Recycle: We should recycle discarded items wherever possible.

SUSTAINABLE DEVELOPMENT-Balancing the need to use resources and also conserve them for the future is called sustainable development.
