1. Natural Resources
And Its
Management

2. INTRODUCTION
Resources-Resources (or natural capital) are
goods or services that have some value to
humans.
Natural resources are materials and components
(something that can be used) that can be
found within the environment
Eg.
Natural resource is anything obtained from
the environment to satisfy human needs.

3. Classification of natural resources
•

4. Human use of Natural Resources
• Humans use natural resources to help
meet their three basic needs.
• The use of natural resources to meet
these needs is in two forms,
a)consumptive use and
b)non-consumptive use.

5. Consumptive Use
• Using a natural resource so that the
amount used no longer exists.
• Each time that resource is used, its
supply is reduced.
• An example of consumptive use is
hunting.
– Once that animal is killed and
removed from the wild, it no longer
exists.

6. Non-consumptive Use
• Using a natural resource without
reducing its supply.
• An example of non-consumptive
use is watching wildlife.
–It is possible to enjoy the beauty of
the wildlife without killing or
removing it from the wild.
–It is being used for enjoyment, not
being consumed.

7. Human Impact on Natural Resources
• Virtually all human activities impact on natural
resources.
• From the use of water to bath to the use of
animals for food, natural resource use is
unavoidable.

8. Some example of
natural resources

9. FOREST

10. Forest depletion
• Use and overexploitation
• Deforestation
CAUSES OF
DEFORESTATION
FUEL WOOD CONSUMPTION
AGRICULTURE EXPANSION
DEVELOPMENTAL
PROJECTS
OVER GRAZING
INDUSTRIAL
DEVELOPMENT

11. Forest cover cover past and present

12. Effect of deforestation
•Erosion of soil
•Disruption of the water cycle
•Loss of biodiversity
•Flood and drought
•Climate change

13. FOREST MANAGEMENT
• Raise public and political awareness
• Joint forest management (JFM)
• Social forestry ,
• Agro forestry
• Farm forestry
• Forest conservation act
• Biodiversity act
• Wild life park and protected area

14. Water
• A tasteless, colorless, liquid
natural resource. All living things
need water to survive.

15. FRESH WATER RESOURCES

16. WATER resource depletion
AGRICULTURE ACTIVITY DISCHARGE OF SEWAGE
INDUSTRIAL EFFLUENTOCEAN DUMPINGEUTROPHICATION

17. Impact of water depletion
• Causes the death of many aquatic animal.
• Spread of water borne disease.
• Harms the food chain.
• Ground water pollution.

18. Water management
• Legislative measure to check over exploitation
of water resources –eg. Water pollution and
control act (1974),water cess act(1977)
• Rain water harvesting
• Water shed management
• Changing agricultural practices
• Recycling and reuse of water
• Flood management

19. Mineral resources
• Fossil fuels are natural resources
used to provide energy.
–Fossil fuels took millions of years to
make.
–They are the remains of
decomposed plants and animals.
–Their energy comes from the
energy produced by the plants and
animals.

20. Depletion of mineral resources
• Due to excessive usage
• Low efficient technology
• Due to increasing the number of vehicles

21. Effect of mineral resource depletion
• Increase the global warming
• Land degradation
• Land slide
• Alter the nutrient cycle

22. Energy resource management
• Legislative measure to check over exploitation
• Improve the technology
• Increase the efficiency of electrical instrument
• Use of alternative of coal petroleum and gas for
electricity
Changing public attitude
