CHAPTER 1, RESOURCES
MEANING
OF RESOURCE
Anything
that can be used to satisfy a need or has value can be called a resource.
Water,
electricity, rickshaw, vegetable and textbook all have utility and hence are
considered as resources.
All the resources have value or worth. Some
resources have economic value, some do not. Some may become valuable only over
a period of time.
- Time and technology are the two factors that that change substances to resources
- People themselves are the most important resource. and
discoveries that lead to the creation of more It is their ideas,
knowledge, inventions 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 categorized 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
renewability, 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.
