3. INTRODUCTION
The ecological balance and ecosystem
stability are duly maintained by the nature
itself but the emergence of modern
industrial era has disturbed the ecological
balance through heavy industrialization,
technological revolution, faster growth of
means of transportation rapacious,
unplanned urbanization etc.

4. NATURAL RESOURCE
MANAGEMENT
“Natural Resource management refers to
the management of natural resources such
as land , plants, animals, water and soil
with the sole focus on how management
affects the quality of life for both present
and future generations”

5. Need For Natural Resource
Management
Natural resources are limited there is a
crisis for these resources hence needs to
be managed.
There is an absolute need to manage
resources for the exitence of living beings
on earth and their survival.
There is a need to manage our resources
today , not just for us but our future
generations too.

6. Objectives of Natural Resource
Management
To maintain ecological
diversity
To provide resources for
future generations
To maintain employment
facilities for people.

7. Approaches to Natural Resources
Management
 Various rules and regulations have been
passed by the government over the years
to ensure that our wildlife does not
become extinct and are not hunted down.
 The government has also passed rules and
laws to limit large scale industries from
the use of excess water and rules for
proper sewage to ensure water bodies
around industrial areas are not getting
contaminated.

8.  Water is being treated regularly to
provided drinkable water to the people.
 The government has adopted measures
and encourage people to recycle and reuse
products as much as possible.
 Use of plastic has also been banned which
reduces damage causes to nature to quite a
large extent.
 Clean India mission was launched by P.M
Narendramodi

9. Resources
•Resources
• Air, Water
• Land, soil, forest , etc.

10. Classification Of Resources
Two Types
Resources
Renewable
Resources
Non Renewable
Resources

11. Renewable Resources
Renewable resources are those
resources that can be renewed
naturally over time.
Air, water, wind, solar energy etc
are all renewable resources.
Renewable resources can be
easily renewed by nature.

13. 1.Solar Energy
Sun is a big source of energy.
The energy that be get from the
sun is called solar energy.
Now a day, solar energy is being
used to cook food with the help
of solar cooker, heat water, light
streets pump water for irrigating
fields etc.

15. 2.Hydro Energy
 Water is important natural resources.
 All living organisms need water to live.
 Humans need water for many purposes
such as drinking, cleaning, cooking and
for growing crops.
 Water flowing into the river or water
stored in a dam is sources of hydro energy
 Hydro energy is convert it into electrical
energy.

17. Wind energy
Winds are constantly being created in nature.
The windmill is a source of electrical energy.
These windmills are generally established
only at places where most of the days in a
year experience strong winds.
The energy from this wind is used for
grinding grain, pumping water and to
produce electricity.
In India, many windmills have been set up in
different places such as Tamil Nadu,
Maharashtra, Rajasthan, Kerala, West Bengal
and Gujarat.

19. Biogas
Biogas is a type of fuel which is a
mixture of gases such
as methane, carbon dioxide, hydrogen
etc which is obtained by
decomposition of animal and plant
wastes like animal dung, with the help
of micro-organisms in the presence of
water.
It is used as fuel in gas stove
especially in rural areas.

21. Wood
Wood is an ancient and traditional source
of energy.
It is mainly a mixture of many
carbohydrate compounds.
Wood is used to cook food. It leads
to deforestation and pollutes air also.
 In India, still in many villages, they use
wood chullas to cook food every day.
While having ill effects on the
environment, it is also harmful to human
health

23. Hydrogen
It is a good source of energy because
it does not create pollution and
produce maximum energy on
burning.
Hydrogen has the potential to be the
answer to all our energy and fuel
troubles.
Technology is currently being
developed to fully utilize hydrogen
efficiency.

25. Alcohol
Alcohol has many commercial and
medical purposes.
It can use for producing energy.
It can be obtained while making sugar
from sugarcane.
 Thus it is a very cheap source of energy.
A mixture of petrol and alcohol is being
used as a fuel in automobiles.
This mixture is called ‘Gasohol’.

27. Air
All living things need air to
breathe.
Therefore, air is an
important natural resource.

29. Water
All living things water in order to
survive. And the water cycle means
we will essentially never run out of
the water.
 But we must be careful not to pollute
water and make it unusable.
Drinking and clean water are already
scarce in the world.

31. Soil
It is an important resource as this
is the layer where plants grow.
We all need food in order to
survive.
We get most of our food from
crops grown in the soil.

33. Non Renewable resources
The other classification of resources is
non-renewable resources.
 Non-renewable resources are those
natural resources that are available in
limited quantity.
These resources cannot be renewed or
replenished in short duration. Therefore
they are also known as exhaustible
resources.
Examples- coal, natural
gas, petroleum etc.

34. Coal
Coal is a black rock that can be burned to
produce energy.
Coal is made from fossilized plants. It is
ranked depending on how
much “carbonization” it has gone
through:
peat is the lowest rank of coal as it has
gone through the least amount of
carbonization, whereas anthracite is the
highest rank of coal.

36. Oil
Another form of non-renewable energy is oil,
a very versatile liquid fossil fuel that can be
used for energy generation as well as a wide
range of other applications.
It is usually stored deep beneath the earth’s
surface.
Oil is extracted by drilling into where it is
trapped between 2 layers of rock, a pipe is
then inserted in the hole to siphon it to the
surface.
When the so-called drill rigs are set up,
either onshore or offshore, oil can be
extracted 24/7 for several decades.

38. Natural gas
Natural gas is is the second most abundant
non-renewable energy source.
While coal is a rock and oil is a liquid,
natural gas is – as the name suggests – a gas.
Natural gas is predominantly methane.
 It was formed like the other fossil fuels with
pressure and heat pressing on organic
material over millions of years.
 Unlike oil and coal deposits, natural gas is
not found in big open pockets but rather
trapped in rock formations

40. Nuclear power
Nuclear power is not a fossil
fuel but it is a non-renewable
form of energy.
Nuclear power is considered non-
renewable because the material
used in nuclear power plants –
uranium – is a non-renewable
resource

42. Advantages of renewable energy
• Renewable energy won’t
run out
• Maintenance
requirements are lower
• Renewables save money

43. Disadvantages of renewable
energy
• Higher upfront cost
•Intermittency
•Storage capabilities

44. Advantages of Non-Renewable
Energy
They are
abundant
and
affordable.
It is cost
effective
and easier
to product
and use.

45. Disadvantages of Non-Renewable
Energy

46. Forest management
Forest management is
a branch of forestry concerned with overall
administrative, legal, economic, and social
aspects, as well as scientific and technical
aspects, such as silviculture, protection, and
forest regulation.
This includes management
for aesthetics, fish, recreation, urban
values, water, wilderness, wildlife, wood
products, forest genetic resources, and
other forest resource values

48. Principles of Forest Management
• “the greening of the world” through
planting and conserving forests.
• To be managed in order to meet the
social, economic, ecological,
cultural and spiritual needs of
present and future generations.
• Pollutants that harm forests
should be controlled

49. Forests managed in two ways
even-
aged
forests
uneven-
aged
forests

50. Purposes And Techniques Of
Forest Management
•Multiple-use concept
•Sustained yield
• Forest products

51. water management
Good water management will involve
organizing water so that everyone has
enough, and controlling water supplies
and water treatment centers (and other
equipment and logistics relating to water)
so that they work in the best possible
way. It thus often involves some
knowledge of the chemical properties of
water.

53. Importance of water management
• Drinking water
• Washing and cleaning
• Agriculture
• Leisure and fun
• Biodiversity

54. Methods of water management

55. Bioremediation
“Bioremediation is a waste management
technique that involves the use of
organisms to remove or neutralize
pollutants from a contaminated site.”
Bioremediation is a “treatment that uses
naturally occurring organisms to break
down hazardous substances into less
toxic or non toxic substances.”

57. Why Bioremediation is
Important?
•It uses no
chemicals
•It can allow waste
to be recycled

58. Types of Bioremediation
• Phyto remediation
• Bioventing
• Bioleaching
• Land farming
• Bioreactor
• Composting

59. Types of Bioremediation
• Bioaugmentation
• Rhizofiltration
• Biostimulation

60. What is an ETP?

•Sludge: Solid part separated from
waste water by ETP.

62. Need of ETP
 •To clean industry effluent and recycle it for
further use.
 •To reduce the usage of fresh/potable water in
Industries.
 •To cut expenditure on water procurement.
 •To meet the Standards for emission or discharge
of environmental pollutants from various
Industries set by the Government and avoid
hefty penalties.
 •To safe guard environment against pollution
and contribute in sustainable development.

63. Treatment Levels & Mechanisms
of ETP
•Treatment levels:
