RESOURCES-
- All materials available in our environment which
satisfy our needs are called as Resources.
- All resources have some value. Value means worth. Some resources
have economic value and some do not, but both are important and satisfy
human needs.
- Some resources can become economically valuable with
time.
- Time and technology are the important factors that
change substances into People themselves are the most important resource.
It is their ideas, knowledge, inventions and discoveries that lead to the
creation of more resources.
- Each discovery or invention leads to many others. For
example-
- Discovery of fire led to the practice of cooking
- Invention of the wheel resulted in the development of
newer modes of transport.
TYPES OF RESOURCES:
- Resources are catogorised into natural, human made and human.
1. Natural resources are those resources that are drawn from nature and are used
without much modification-air, water, soils, minerals are the natural
resources.
- Natural resources are classified into different groups
depending upon their level of development and use, origin, renewability
and distribution
- Natural resources also called as 'gifts of nature'.
(i) On the basis of level of their development and use, natural resources can be classified into -
|
ACTUAL RESOURCES
|
POTENTIAL RESOURCES
|
|
Those resources whose
quantity is known.
|
Those resources whose
entire quantity may not be known
|
|
These resources are
being used in the present.
|
These are not being
used at present and could be used in the future.
|
|
For e.g. Coal of
Germany, Petroleum in the West Asia
|
For e.g. The Uranium
in Ladakh
|
(ii) On the basis of origin, the natural resources can be
|
BIOTIC RESOURCES
|
ABIOTIC RESOURCES
|
|
It includes all the
living things.
|
It includes all the
non-living things.
|
|
For example- Plants
& animals
|
For example- Soil,
rocks, minerals
|
(iii) On the basis of renewablitiy, natural resources can be categorized into
|
RENEWABLE RESOURCES
|
NON-RENEWABLE RESOURCES
|
|
Those which can get
renewed or replenished quickly are called as Renewable resources. They are
also called as Inexhaustible resources.
|
Those which have a
limited stock. Once the stocks are exhausted it may take thousands of years to
be renewed or replenished are called as Non-renewable resources. They are
also called as Exhaustible resources
|
|
For e.g. solar and
wind energy.
|
For e.g. such as coal,
petroleum and natural gas.
|
(iv) On the basis of distribution, natural resources can be classified into-
|
UBIQUITOUS RESOURCES
|
LOCALIZED RESOURCES
|
|
Ubiquitous resources
are found everywhere on the earth. Land, water, air are ubiquitous resources.
|
Localized resources
are found only in certain places, like copper and iron ore.
|
(v) The distribution of
natural resources depends upon, number of physical factors like terrain,
climate and altitude(height).
(vi) The distribution of
resources is unequal across the earth.
2. Human Made Resources:
Human resource refers to
the number(quantity) and abilities (mental and physical) of the people.
(i) The resources which
are created from the natural resources by the human resources by the human
beings to produce useful products are known as Human made resources. Like
roads, machinery, vehicles, etc.
(ii) Technology is also
a human made resources.
3. Human Resources:
(i) Human resources
refers to the number and abilities of the people. People can make the best use
of nature to create more resources when they have the knowledge, skill and the
technology.
(ii) People are human
resources.
(iii) Improving the
quality of people's skills so that they are able to create more resources is
known as Human resource development.
CONSERVING RESOURCES:
(i) Conservation of
resources refers to using natural resources carefully so that they could be
renewed and continue to be used in future.
(ii) Sustainable use of
resources refers to carefully
utilizing resources and balancing the need to use resources and also conserve
them for the future generation.
(iii) It is our duty to
ensure that all uses of renewable resources are sustainable.
(iv) The diversity of
life on the earth should be conserved.
(v) The damage to
natural environmental system should be minimized.
(vi) There are many ways
of conserving resources.Each person can contribute by reducing consumption,
recycling and reusing things.
