This document discusses natural resources and their classification and conservation. It defines natural resources as materials that occur naturally and meet the needs of living things. Resources are classified as biotic (living) or abiotic (non-living), and as renewable or non-renewable. Specific natural resources discussed include forests, water, minerals, food, and land. Threats to these resources like deforestation, pollution, and overuse are outlined. The summary concludes with conservation methods like afforestation, pollution control, sustainable harvesting, and renewable energy promotion.

1. Role of individual in preserving
natural resources for their
equitable maintenance

2. Natural resources
 Resources that occur naturally and meet the
desires of the entire living beings are known as
natural resources. They resources are considered
valuable in their relatively unmodified (natural) form.
 A commodity is generally considered a natural
resource when the primary activities associated
with it are extraction and purification, as opposed
to creation.
 All the natural resources come from
environment. some of them are essential for our survival while most
of them are essential for satisfying our wants.
 A country's economic standing and independence are base on
long-term sales of its natural resources, also known as commodities,
to other nations.
 Today, population explosion and incresase in man’s greedy nature
have become the main causes for exploitation of natural resources.

3. Classification of natural resources
Natural resouces are classified into two
Types basing on their origin.
They are:
• BIOTIC:These are also known as the
living resources.These are the renewable
resources and include the plants and
animals. Examples of biotic resources
are forests, plants, animals, birds, fish,
and marine organisms. Mineral fuels
can be, but not always are, regarded as
biotic resources since they are derived
from or products formed from decayed
organic matter.
 ABIOTIC:Abiotic resources are resources
that are nonliving. These resources fall
into the larger category of natural resources, which occur naturally in
the environment and are not created or produced by humans or human
activity.examples are minerals,water,land,energy resources etc…

4. Basing on their availability natural resources are classified into two types.
They are:
1. Renewable resources
2. Non-renewable resources

5. Renewable resources:
 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 ecosystem
• Renewable resources are those
whose supply becomes available for
use at different time intervals and in
which present use does not diminish
future supply.
• Tree and plant biomass, water and wildlife are a few renewable
‘natural’ resources.
• Renewable sources have low carbon emissions, therefore they are
considered as green and environment friendly.

6. 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.
• Non-renewable sources are not environmental
friendly and can have serious affect on our
health.
• Non-renewable sources will expire some day
and we have to us our endangered resources
to create more non-renewable sources of
energy.
• Non-renewable sources release toxic gases in
the air when burnt which are the major cause
for global warming.
• Examples for non renewable resources are fossil fuels, natural gas, oil
and coal.

7. Types of natural resources
Different types of natural
resources are:
Forest resources
Water resources
Mineral resources
Food resources
Land resources
Energy resources

8. Forest resources
Forests are classified into :
•Tropical forests
•Temperate forests
•Coniferous forests
Threats to forest resources:
Deforestation: process of
cutting doun the trees in
arid, semi arid, moist regions is
know as deforestation.causes
for deforestation are timber extraction,dam
construction,cultivation,mining,pollution..etc

9. Measures to control
deforestation
• Implement afforestation
programmes
•Overgrazing of cattle should be
reduced
• Control the usage of paper
•Forest conservation act should be
strictly implemented
• Recycle and buy recycled products.
•When a tree is cut,one plant should
be grown in order to maintain
balance.
•Educate people on ecological value
of tree, reduce use of timber, plant
•Provide alternate fuel to the forest
fringe poor people to reduce
pressure on firewood for daily need.

10. Water resources
Threats to water resources:
•Dumping industrial waste
•Dumping pesticides and
organic waste
•Eutrophication
•Bio magnification
•Thermal pollution
•Oil spills

11. Measures to conserve water resources
Rain water harvesting must be done.
 Sewage treatment should be
implemented.
 Use drip irrigation for shrubs and
trees to apply water directly to the
roots where it's needed.
 Use a water-efficient showerhead.
They're inexpensive, easy to install,
and can save you up to 750
gallons per month.
 Look for products bearing
the EPA WaterSense Label
for items that been certified
to save 20% or more without
sacrificing performance.
 Water-saving steam
sterilizers, for use in
hospitals and health care
facilities.
Improved water management
practices that reduce or
enhance the beneficial use of water.

12. Mineral resources
•A 'Mineral Resource' is a concentration or occurrence of material of
intrinsic economic interest in or on the earth's crust in such form, quality
and quantity that there are reasonable prospects for eventual economic
extraction
Mineral resources are classifies into metallic
and non metallic:
• Metallic:examples are iron,alluminium,
copper,gold.etc..
• non-metallic: examples are coal,gypsum,
silica ,limestone.etc..
Threats of mining:
•Disturbance to mantle layer
•Earthquakes
•Tsunami
•Drowning of land
•Deforestation
•Acid mine drainage

13. Conservation methods
Implementation of bio-mining/leaching
technology.
Enhanced oil recovery (eor).
Usage of bio fuels.
Surface mining control and reclamation act
should be strictly implemented.
Mining activities should me done under
strict supervision of authorities
The mined out areas have to be back filled
and then rehablitated for development of
vegetation.

14. Food resources
Food is any substance consumed to provide nutritional support for the
body. It is usually of plant or animal origin, and contains essential
nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals.
The substance is ingested by an organism and assimilated by the
organism's cells in an effort to produce energy, maintain life, or
stimulate growth.

15. Conservation of food resources
Implement the following methods to get chemical free food.:
Organic farming:it is a process in which both modern and traditional
methods of farming are utilized.
Mulching:process of adding or layering dry leaves
Composting:conversion of complex materials into simpler ones with the
help of micro organisms.
Usage of Green manure.

17. land occupies nearly
20 percent of the earth
surface. It covers
around 13000 million
hectares of the area.
The houses, roads and
factories occupy nearly
one third of the land.
The forests occupy
another one third of the
land. The rest of land is
used for ploughing and
for meadows and
pastures. The soil
forms the surface layer
of land which covers
more than the 80
percent of land.

18. Conservation of land resources
Measures to overcome soil erosion
1. Biological control:adapting of some living systems to improve
fertility.they are
A. Mulching
B. Polyculture
C. Crop rotation
2. Mechanical control:
A. Contour ploughing is a measure to conserve our land.
By this method, the fields are ploughed, harrowed and
sown along the natural contour of the hills.
B. By terracing method: A series of wide steps are made
along the slop following the contours. This method is
very common in rice growing regions.
3. By educating, informing and sensitizing all landholders about
various aspects of this precious resources and their
sustainable use
4. Under the afforestation and reforestation programmes, planting
of trees, bushes and grass help to check the soil erosion.

19. 5. Strict actions are taken to check reckless felling of trees and
overgrazing.
6. Shelter belts (rows of trees) are planted on the margins of desert areas
to check the fury of wind.
7. Construction of dams and gully-trap inculcate the water-harvesting.

20. Energy resources
Energy is the capacity to do work and is required for life processes. An
energy resource is something that can produce heat, power life, move
objects, or produce electricity.
Matter that stores energy is called a
fuel.
Energy resources are
Classified into two types.
They are:
•Renewable:solar energy,
wind energy,tidal energy,
geothermal energy etc..
•Non renewable energy:
coal,petrol,diesel.etc..

21. Conservation of energy resources
•CFLs use 60% less energy than a regular bulb. This simple switch
will save about 300 pounds of carbon dioxide a year.
•Change your travel behaviour, think more in terms of public
transportation, if possible, walk or ride your bicycle instead of taking
the car.
•Turn off lights and appliances when you are not using them, use
energy-saving light bulbs.
•Use a microwave instead of a stove to reheat food.
•Use rechargeable batteries instead of disposable batteries.
•Install skylights in the roof or walls to reduce the need for artificial
lighting.
•Plant shade trees and paint your house a light color if you live in a
warm climate, or a dark color if you live in a cold climate.
Reductions in energy use resulting from shade trees and
appropriate painting can save up to 2.4 tons of CO2 emissions per
year. (Each tree also directly absorbs about 25 pounds of CO2 from
the air annually.)
•Don’t overload refrigerators; they operate more efficiently when air
circulation is not restricted.
