Topic: Resources

2. What are
resources?
•Anything that can be
used to satisfy a need
is a resource. For
example: land,
minerals, air etc.

3. Value of a resource
•The purely economic
value of a resource is
controlled by supply
and demand. This is,
however, a narrow
perspective on
resources as there
are many things that
cannot be measured
in money.

4. •Natural resources like
forests, mountains etc.
are considered
beautiful so they have
aesthetic value.
Resources also have an
ethical value as well,
because it is widely
recognized that it is our
moral duty to protect
and conserve them for
the future generations.

5. Characteristics of
resources
•Resources have three
main characteristics:
utility, quantity (often
in terms of availability),
and consumption.
However, this
definition is not
accepted by some, for
example deep ecologists
who believe that non-
human elements are
independent of human
values.

6. Types of resources:
Natural resources
•Natural resources are
derived from the
environment. Many of
them are essential for
our survival while
others are used for
satisfying our needs.
Natural resources may
be further classified in
different ways; on the
basis of origin,
resources may be
divided into.

7. •Biotic - Biotic
resources are those
obtained from the
biosphere. Forests and
their products, animals,
birds and their
products, fish and other
marine organisms are
important examples.

8. •Minerals such as coal
and petroleum are also
included in this
category because they
were formed from
decayed organic matter.
•Abiotic - Abiotic
resources comprise
non-living things. For
examples include land,
water, air and minerals
such as gold, iron,
copper, silver etc.

10. •On the basis of the
stage of development,
natural resources may
be called:
•Potential Resources -
Potential resources are
those that exist in a
region and may be used
in the future. For
example, mineral oil
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.

11. •KEYWORD
•Stock are the
materials in the
environment which
have the potential to
satisfy human needs
but do not have the
appropriate
technology to access
them.

12. •For example, hydrogen and
oxygen are two inflammable
gases present in water, but we
do not have the technology to
use them from water.
•Reserved Resources are the
subset of stock, where use
has not yet been started and
are saved for future use.
•Actual resources- are those
that have been surveyed, their
quantity and quality
determined, and are being
used in present times. For
example, petroleum and
natural gas obtained from the
Mumbai High Fields.

13. •The development of an
actual resource, such as
wood processing
depends upon the
technology available
and the cost involved.
That part of the actual
resource that can be
developed profitably
with available
technology is called a
reserve.

14. •On the basis of
renewability, natural
resources can be
categorized into:
•Renewable
Resources -
Renewable resources
are those that can be
replenished or
reproduced easily.
Some of them, like
sunlight, air, wind, etc.,
are continuously
available and their
quantity is not affected
by human consumption.

15. •Many renewable
resources can be
depleted by human use,
but may also be
replenished, thus
maintaining a flow.
Some of these, like
agricultural crops, take
a short time for
renewal; others, like
water, take a
comparatively longer
time, while still others,
like forests, take even
longer.

16. •Non-renewable Resources
- Non-renewable resources
are formed over very long
geological periods.
Minerals and fossils are
included in this category.
Since their rate of
formation is extremely
slow, they cannot be
replenished once they are
depleted. Out of these, the
metallic minerals can be
re-used by recycling them,
but coal and petroleum
cannot be recycled.

17. •On the basis of distribution,
natural resources can be
classified into:
•Ubiquitous resources- the
resources that can be
found everywhere. For
example- air, light, water
etc.
•Localized-are those that
can be found only in
certain parts of the world.
For example-copper and
iron ore, thermal power
plant etc.

19. Human resources
•Human beings are also
considered to be
resources. The term
Human Resources can
also be defined as the
skills, energies, talents,
abilities and knowledge
that are used for the
production of goods or the
rendering of services.

20. Human-made
resources
•Sometimes, natural
substances become
resources only when
their original form has
been changed. Iron ore
was not a resource
until people learnt to
extract iron from it.
People use natural
resources to make
buildings, bridges,
roads, machinery and
vehicles,

21. Iron ore
•which are known as
HUMAN-MADE
RESOURCES .
Technology is also a
human made resource.

23. Resource
conservation
•Using resources carefully
and giving them time to get
renewed is called resource
conservation. Balancing
the need to use resources
and also conserve them for
the future is called
sustainable development.

24. • There are many ways of
conserving resources. Each
person can contribute by
reducing consumption,
recycling and reusing thing.
Ultimately it makes a
difference because all our
lives are linked.
•The future of our planet and
its people is linked with our
ability

25. •to maintain and preserve
the life support system that
nature provides. Therefore
it is our duty to ensure that
-
• All uses of renewable
resources are sustainable
• The diversity of life on the
earth is conserved
• The damage to natural
environmental system is
minimized.

26. Resources in India
•India's inland water
resources comprising
rivers, canals, ponds and
lakes and marine
resources comprising the
east and west coasts of the
Indian ocean and other
gulfs and bays provide
employment to nearly 6
million people in the
fisheries sector.
•

27. • In 2008, India had the
world's third largest
fishing industry.

28. •India is rich in certain
energy resources
which promise
significant future
potential - clean /
renewable energy
resources like solar,
wind, bio-fuels.

29. Mineral resources in
India
•India's major mineral
resources include Coal
(fourth-largest reserves in
the world), Iron ore,
Manganese, Mica, Bauxite,
Titanium ore, Cromite,
Natural gas, Diamonds,
Petroleum, Limestone and
Thorium (world's largest
along Kerala's shores).

30. •India's oil reserves,
found in Bombay High
off the coast of
Maharashtra, Gujarat,
Rajasthan and in
eastern Assam meet
25% of the country's
demand.

36. Other major
resources: oil and
natural gas
•India of proven oil
reserves as of January
2007, which is the
second-largest amount
in the Asia-Pacific
region behind China.
Most of India's crude oil
reserves are located in
the western coast
(Mumbai High)

37. •and in the northeastern
parts of the country,
although considerable
undeveloped reserves
are also located in the
offshore Bay of Bengal
and in the state of
Rajasthan.

38. •India had 38 trillion cubic
feet of confirmed natural
gas reserves as of January
2007.A huge mass of
India’s natural gas
production comes from the
western offshore regions,
particularly the Mumbai
High complex. The
onshore fields in Assam,
Andhra Pradesh, and
Gujarat states are also
major producers of natural
gas.
