TYPES OF RESOURCES

What do you RESOURCES :- Any objects that is useful in making the life of
know about human beings comfortable is a resource.
resources?
So the main objectives of the lesson is we are going to see about …..

Anything that fulfills human needs its called a resource.

Examples of some resources are:-
Air that we breathe.
Water we drink.
Food we eat.
Minerals we use.
Means of communications.

Now we will see about the characteristics that constitute a resource.

A resource must satisfy our need – a
resource should be available to satisfy
human needs.

Should be developed and used –a resource
available should be developed and available
to use.

It should be accessible to human.

How does something It should have some value – a resource
become a resource? should be of economical and social
1. Things become a value.

resource only when they
have value.
2. Its use gives it a value.

VALUE MEANS WORTH

Economic value is a concept in cost benefit analysis. Some resources have economic value some do not.
For example : Metals may have an economic value, a beautiful landscape may not, but both are important and
satisfy human needs.
Some resources can become economically valuable with time.

SOCIAL VALUE

Resources are important for the development of any country.

Example : to generate energy we need fossil fuels.

Natural resources is the key input in the production process that stimulates economic growth.

A resource should be cheap – for developing a resource it should not cost too much.
It should suit the requirements of the new technology and development – a resource should suit the requirements of
human being when new technologies are used.

CLASSIFICATION OF RESOURCES

NATURAL HUMAN- MADE HUMAN

Abiotic Potential Non-renewable

Natural Resources :-
What are natural resources?

Something which occurs in nature are
classified as natural resources.

Example: Air, Water, Sunlight or
Resources that satisfy human wants
or needs such as Food, Raw materials,
Minerals.

Natural resources are further classified on :- BIOTIC – LIVING
1.Origin.
2.Stage of development. Biotic
3.Renewability.
Biotic
1.Basis of Origin :-
Origin means from where they are derived or got.
On the basis of origin, it is again divided into two :-
a)Abiotic–Nonliving(These include Land, Soil, Water,
Minerals etc).
b)Biotic – Living ( Natural vegetation and forest, Wildlife etc.)

ABIOTIC–NONLIVING

Abiotic Abiotic

2. STAGE OF DEVELOPMENT

Resources classified as Potential and actual.

a)Potential – Resources existing, located
but not utilized and developed.

Maybe developed and utilized in future.
Example: Tidal energy, Solar energy,
Geothermal energy Resources waiting to
be tapped.

TIDAL ENERGY SOLAR ENERGY GEO THERMAL ENERGY

B) ACTUAL RESOURCES

These resources have been surveyed and assessed and have been currently
used by humans.

Example: Iron ore and coal extracted and used in Iron and steel plants.

ACTUAL USE OF RESOURCES DEPENDS ON THEIR

Accessibility of resource.
Depends on time.
Technology.
On human knowledge.
Ideas which transform resources into

something valuable.

3.Renewability :-
On the basis of renewability it is categorized as
Renewable and Non-renewable.

a)Renewable:
What do you mean by the term Renewable?
Resources which can be replenished in a short
period of time.

Example: Solar power, Wind energy and Tidal energy,
Air, Water.

Easily available and widely distributed.
Renewable resources regenerate themselves either
through a cyclic flow process or reproductive
process.

b)Non-Renewable :
They are non-replenishable or it may
take millions of years to be renewed.

Example :
Mineral ores and fossil fuel.

It takes a few years to use up an entire
coal seam – thick layer of coal.

To produce one such seam it may
require a whole period of geologic time
or Millions of years.

Renewable

Solar energy Wind energy Crops

Non-Renewable

Mineral ores Fossil fuel Coal



B) Human-made :-
How does Human-made resource assume significance?
The proper use of these natural resources depends
upon the technologies used. These technologies make
the resource significant. They play a vital role in the
utilization and development of natural resources.

They include :
Technical expertise.
Government structures.
Social and cultural setup.
Political and economical institutions.



Natural resources have a double edge effect on economic growth, in
that the intensity of its use raises output, but increases its depletion rate.

Role of Natural resources in economic Development :

Generally economic growth, poverty reduction and industrial
development are the top priorities of developing countries.

The natural resources provide soil to grow food and water for
drinking, washing and irrigation.

Forest and rivers provide fish to eat or export and raw materials for a
wide range of industries.

Natural resource is a key input in the production process that
stimulates economic growth.

C) HUMAN RESOURCES
These resources constitute human being
themselves.

SALIENT ASPECTS OF HUMAN RESOURCES

• Without human beings no resource can be
utilized.

• This is assessed both in the terms of
quality and quantity i.e (there should be
enough humans to exploit natural
resources).They must also have the
techniques to utilize them in the best way.

Along with educational expertise we need a healthy human population.

HUMANS MUST HAVE THE HEALTHY HUMAN POPULATION
TECHNIQUES TO UTILIZE
NATURAL RESOURCES IN THE BEST WAY

Conservation of Resources :-
Conservation includes both protection and effective use of
natural resource .

Earth resources are non- renewable such as minerals , oil,
gas, coal etc.

(or) Renewable such air, water, crops etc.

At this point we can see what is
sustainable development.

It is to use the resources in proper
way for now and also for future
generations.

Now this conservation is the need
of the hour with the increasing
population and increasing
production.

As of now we are over-
dependent on non-renewable
resources.



Ways of Conservation :
a) Look for alternatives to resources.

Example : use aluminum in place of copper.

b) Sometimes exploitation may have unintended consequences.
Example : When coal deposits undergo strip mining, the flow of ground water may be disturbed.

c) Poor farming methods have ruined farm lands.
Avoid disastrous changes to increase agricultural use.

d) Adopt proper waste management.
To avoid fumes from automobiles and smokes
from factories.

e) Growth of population should be controlled for sustainable management of resources.

FINALLY A SUCCESSFUL MANAGEMENT OF RESOURCES IS TO MAINTAIN AND
ENHANCE THE QUALITY OF ENVIRONMENT WHICH WILL MEET THE PRESENT
NEEDS AND ALSO SUSTAINED DEVELOPMENT FOR FUTURE GENERATIONS.
