Anything which can be used for satisfying the human needs is called a resource.
For Example – Animals , Plants , land etc.
Explanation:
Classification of resources
Resources can be classified on different bases
→On the basis of Origin
1 Biotic Resources – All living organisms in our environment are called biotic resources.
2 Abiotic Resources – All non-living things present in our environment are termed as abiotic resources.
→On the basis of Exhaustibility :
Renewable Resources: Resources that can be replenished after a short period of time are called Renewable Resources.
Non-renewable Resources: Resources which takes million years of time to replenish are called non-renewable resources.
→On the Basis of ownership:
Individual: Resources owned by individuals are called Individual Resources.
Community: Resources owned by community or society are called Community Owned Resources.
National Resources: Resources owned by Individual Nations are called National Resources.
International Resources: Resources regulate by International bodies are called International Resources.
→On the basis of Status of Development
Potential Resources: Resources which are found in a particular region, but not yet used properly.
Developed Resources: Resources which are developed and surveyed for utilization and are being used in present time are known as Developed Resources.
Stock: Resources that are available, but we do not have proper technology to used them are called Stock.
Reserves: Resources which are available and the technology to use them is also present but they are yet to be used are called Reserves.
What is Sustainable Development ?
The Development which takes place without damaging the environment and compromising with needs of future is called sustainable development.
Resource Planning
Resource planning refers to the strategy for planned and judicious utilisation of resources. Resource planning is essential for sustainable existence of all forms of life.
Classification of Soil
- Alluvial Soil
- Black Soil
- Red Soil
- Laterite Soil
- Arid Soil
- Forest Soil
- Mountain Soil
Soil Erosion and Soil Conservation
Removal of top soil is called soil erosion. Intense farming, grazing, construction activities and other human activities; along with deforestation have led to soil erosion. Soil erosion; if not checked in time; can even lead to desertification.
Soil conservation is important to prevent soil erosion. Soil conservation can be done by many methods. Afforestation is the main method because trees hold the topsoil in place. Terrace farming and shelter belt planting also help in soil conservation.

➢ Resources are the means to fulfil the basic
needs of man through the use of technology.
They are economically efficient and culturally
acceptable.
➢ Resources can be two types: natural and
human.
Natural resources are gifts of nature like rivers
while human resources consist of quality of
individuals and human made structures and
institutions.
➢ Resources can be classified on the basis of
origin, exhaustibility, ownership and the status
of development.
➢ On the basis of origin, resources are of two
types, viz., biotic resources and abiotic
resources while on the basis of exhaustibility,
resources are renewable and non-renewable.
➢ On the basis of ownership, resources are
individual community owned, national and
international resources; on the basis of the
status of development, resources are potential,
developed stocks and reserves.
➢ Indiscriminate use of resources has led to
the serious global problems like global
warming, ozone layer depletion, environmental
pollution and land degradation.
➢ These problems attract the concern of
international communities and cause the rise
of a new concept i.e. sustainable development.
