2. WHAT IS A RESOURCE?WHAT IS A RESOURCE?
A resource is a source or supply from which
benefit is produced. Typically resources are
materials, services, staff, or other assets that
are transformed to produce benefit and in the
process may be consumed or made unavailable.
All the useful elements of environment which
satisfy human needs are called resources.

3. Benefits of resource utilization may include
increased wealth, meeting needs or wants, proper
functioning of a system, or enhanced well being.
From a broader biological or ecological
perspective a resource satisfies the needs of a
living organism

4. Three Types of ResourcesThree Types of Resources

5. NATURAL RESOURCESNATURAL RESOURCES
Resources drawn from nature and used without
modification is called natural resources.
Natural resources are materials and components
(something that can be used) that can be found
within the environment. Every man-made product
is composed of natural resources (at its
fundamental level). A natural resource may exist
as a separate entity such as fresh water, and air, as
well as a living organism such as a fish, or it may
exist in an alternate form which must be processed
to obtain the resource such as metal ores, oil, and
most forms of energy.

6. NATURAL RESOURCESNATURAL RESOURCES
Natural resources are derived from the
environment. Many natural resources are
essential for human survival, while others
are used for satisfying human desire.
Conservation is the management of
natural resources with the goal of
sustainability. Natural resources may be
further classified in different ways.

7. CLASSIFICATION OF NATURAL CLASSIFICATION OF NATURAL
RESOURCESRESOURCES
Natural Resources can be classified into
different groups depending on-
1. level of development and use
2. origin
3. availability
4. distribution

8. CLASSIFICATION OF NATURAL CLASSIFICATION OF NATURAL
RESOURCES: ON THE BASIS OF RESOURCES: ON THE BASIS OF
DEVELOPMENT AND USEDEVELOPMENT AND USE
1. Actual resources are those that have been
surveyed, their quantity and quality
determined, and are being used in present
times.
2. Potential Resources are known to exist and
may be used in the future. For example,
petroleum may exist in many parts of India and
Kuwait that have sedimentary rocks, but until
the time it is actually drilled out and put
into use, it remains a potential resource.

9. CLASSIFICATION OF NATURAL CLASSIFICATION OF NATURAL
RESOURCES: ON THE BASIS OF RESOURCES: ON THE BASIS OF
ORIGINORIGIN
1. Abiotic resources comprise non-living things
(e.g., land, water, air and minerals such as gold,
iron, copper, silver).
2. Biotic resources are obtained from the biosphere.
Forests and their products, animals, birds and their
products, fish and other marine organisms are
important examples. Minerals such as coal and
petroleum are sometimes included in this category
because they were formed from fossilized organic
matter, though over long periods of time.

1.Non-renewable Resources
A non-renewable resource is a natural resource which
cannot be reproduced, grown, generated, or used
on a scale which can sustain its consumption rate,
once depleted there is no more available for future
needs.
A nonrenewable resource is a natural resource that
cannot be re-made or re-grown at a scale
comparable to its consumption.

2. Renewable resources
Natural resources that can be replaced and reused by
nature are termed renewable. A renewable resource is
a natural resource with the ability to reproduce
through biological or natural processes and
replenished with the passage of time. Renewable
resources are part of our natural environment and
form our eco-system.

2. Renewable resources
Renewable resources are natural resources that can be
replenished in a short period of time. Resources which
can be renewed or replenished quickly. These are
unlimited resource. Renewable resources are replaced
through natural processes at a rate that is equal to or
greater than the rate at which they are used, and
depletion is usually not a worry.
Example : Solar, geothermal, wind energy and water.
Water seems to be unlimited renewable resources.

2. Renewable resources
Renewable resources, such as forests and fisheries, can
be replenished or reproduced relatively quickly. The
highest rate at which a resource can be used
sustainably is the sustainable yield. Some resources,
like sunlight, air, and wind, are called perpetual
resources because they are available continuously,
though at a limited rate. Their quantity is not affected
by human consumption. Many renewable resources
can be depleted by human use, but may also be
replenished, thus maintaining a flow.

20. Using Renewable ResourcesUsing Renewable Resources
Because the world will not be able to depend on oil, gas, and coal forever, we must find other ways
to power the kind of life style that we are accustomed to.
Solar Power
 Solar energy is energy from the sun. We know that global wind
and ocean currents are powered by solar energy. More and more,
people are investing in solar panels on the roof of their home,
whereby solar cells actively collect energy and transform it into
electricity.
 Unfortunately, solar cells work less efficiently on cloudy days and
not at all during the night. Batteries can be used to store solar
energy, but they cannot hold very much and disposing properly of
old batteries can be an issue.
Wind Power
 Wind has been used fro thousands of years as a source of energy
on sailing ships and windmills to pump water. Today, windmills
can be used to generate electricity, usually located on a wind farm.
 Wind produces no waste; however, not many regions of the world
have strong and persistent enough winds to generate electricity.

21. Water Power
 Water wheels have been used for over 100 years to help create
energy to ground grain or cut lumber, creating microhydropower.
 Hydroelectric energy is created releasing large amounts of water
through a man-made dam, which turn turbines, or generators, to
create electricity. Lake Murray Dam (photo right) in Columbia is an
example of a hydroelectric dam.
Geothermal Energy
 Large reservoirs within the ground contain heated water from internal heat
in the earth. This heated water can create steam, thereby producing
geothermal energy.
 Only certain regions of the earth have these geothermal hotspots, usually in
tectonically active areas or volcanic areas, such as Hawaii and Iceland.
Yellowstone National Park would be a very good resource for geothermal
energy.
 While not heard about very often, biomass energy, which is energy
derived from burning organic material like wood, alcohol, or garbage, is
a common renewable energy resource. A drawback of burning these
items, however, is that particles are released into the atmosphere,
potentially increasing air pollution.
Biomass Energy
 Most hydropower dams in the U.S. were built in the mid-1900’s and we are now learning about
the detrimental effects that they have on the environment, including sedimentation of the upstream
reservoir, migration of fish, and sediment starvation as far downstream as the coast!

DISTRIBUTIONDISTRIBUTION
1. Ubiquitous Resources are found everywhere
(e.g., air, light, water)
2. Localized Resources are found only in certain
parts of the world (e.g., copper and iron ore,
geothermal power).

23. HUMAN RESOURCESHUMAN RESOURCES
Human Resources Get Work Done.
Human resources are man and his mind.
Human beings, through the labor they provide and the
organizations they staff, 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.

24. HUMAN RESOURCESHUMAN RESOURCES
People can make the best use of nature to create more
resources when they have the knowledge, skill and
technology to do so. That is why human beings are a
special resource. People are human resources. Education
and health help in making people a valuable resource.
Human resources are people who work to produce a good
or service.
Examples of human resources are a engineers, doctors,
truck driver, plumber, teacher and nurse.

CAPITAL RESOURCESCAPITAL RESOURCES
Capital Resources Aid Production.
Capital/Human-made Resources are the resources made by
human beings .These are either made from natural items or
made newly.
Human-made resources also often referred to as "capital"
includes all the man-made things that help grow an
economy: money, factories, roads, etc. Sometimes natural
substances become resources only when their origin form
has been changed.
Capital resources are resources that can be used to make
more, like money or tools key features of capital are the
availability of money for lending, the level of
infrastructure, the availability and use of tools, machines,
and technologies.

26. HUMAN-MADE / HUMAN-MADE /
CAPITAL RESOURCESCAPITAL RESOURCES
People use natural resources to make buildings, bridges,
roads, machinery and vehicles, which are known as Human
Made Resources. Technology is also a human made
resource.
Different types of businesses have different capital
resources, such as:
Bakery - Heavy-duty mixers for large quantities of dough
and icing; ovens; commercial baking pans; tools such as
spatulas, cookie and biscuit cutters, rolling pins; supplies
like flour, sugar, spices, etc; shelving to store baked breads
and other homemade food; display cases and display trays
for cookies, pies, etc.

Different types of businesses have different capital resources,
such as:
Plant nursery - Greenhouses, sheds and other buildings;
wooden and metal display shelves; pots, hoses, grow lights,
water misters; soils, fertilizers and other garden nutrients;
hand wagons for customers to haul plants; seeds and cuttings
bought to grow more plants; the land the nursery
encompasses.
Computer services company - Desks and chairs for employees;
desktop computers and/or laptops for each desk; computer
software; copiers, fax machines, paper shredders and other
office equipment; phone system and phones; supplies like
paper, pens, staplers, paper clips etc.

28. RESOURCE RESOURCE
CONSERVATIONCONSERVATION
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.
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 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.
