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.
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
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.
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.
