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.

2. āEarth provides enough to satisfy every man's needs, but not every man's greed.ā ā Mahatma Gandhi
3. The term āresourceā means any thing that we use from our environment to achieve our objective. For example, we require bricks, cement, iron, wood etc. to construct a building. All these items are called the resources for construction of building. A resource can be defined as āany natural or artificial substance, energy or organism, which is used by human being for its welfare. These resources are of two types: Natural Resources Artificial Resources
4. āNature is not a place to visit. It is home.ā ā Gary Snyder
5. CONSERVATION OF NATURAL RESOURCES As the human population is continuously growing the consumption of natural resources is also increasing. With the increasing industrialization and urbanization of the modern human society, the use of all the resources is rising. If they are not properly used and well managed, a serious scarcity will result. Therefore we need to conserve the natural resources. This will also upset the ecological balance. Conservation is the proper management of a natural resource to prevent its exploitation, destruction or degradation. Conservation is the sum total of activities, which can derive benefits from natural resources but at the same time prevent excessive use leading to destruction or degradation.
6. Need for Conservation of Natural Resources We know that nature provides us all our basic needs but we tend to overexploit it. If we go on exploiting the nature, there will be no more resources available in future. There is an urgent need to conserve the nature. Some of the needs are : ļto maintain ecological balance for supporting life. ļto preserve different kinds of species (biodiversity). ļto make the resources available for present and future generation. ļto ensure the survival of human race.
7. Conservation of Natural Resources and Traditions of India The need for conservation of natural resources was felt by our predecessors and in India, there was a tradition of respecting and preserving the nature and natural resources. Natural resources were conserved in the form of sacred groves/forests, sacred pools and lakes, sacred species etc. In our country the conservation of natural forests is known from the time of Lord Asoka. Sacred forests are forest patches of different dimensions dedicated by the tribal to their deities and ancestral spirits. Cutting down trees, hunting and other human interferences were strictly prohibited in these forests.
8. This practice is wide spread particularly in peninsular, central and eastern India and has resulted in the protection of a large number of plants and animals. Similarly, several water bodies, e.g., Khecheopalri lake in Sikkim was declared sacred by people, thus, protecting aquati

It is a type of management of natural resources which encourages the utilization of resources that meet current basic needs, while preserving the resources for the needs of future generations.
The term "Natural resources" was first coined and popularized by E.F. Schumacher in the 1970's by his famous book āSmall is Beautifulā. A natural resource can be defined as any substance that is present in nature independently of human industry and that is exploited in some or another way by humans. Forest, Water, Minerals, Food, Energy and Land are apparent examples because these are frequently utilized.

1. Management of natural resources
2.Conservation and judicious use of natural resources
3. Forest and Wildlife, coal and petroleum conservation
4. Peoples participation for conservation
Natural resources (economically referred to as land or raw materials) occur naturally within environments that exist relatively undisturbed by mankind, in a natural form. A natural resource is often characterized by amounts of biodiversity existent in various ecosystems.
Natural resources conservation is a process of rational use and skillful management and preservation of the natural environment with all its resources. Natural resources are finite, limited, and capable of being destroyed by unsustainable use and this can be a limiting factor on sustainable development.

As resources are depleting at faster rate, so here are some methods to conserve natural resources as these are the means to satisfy many need of human life .
Natural Resources
Renewable and non-renewable resources
Forest Resources
Water Resources
Mineral Resources
Food Resources
Energy Resources
Land Resources
Role of an individual in conservation of natural resources
Natural resources are the resources available in a nature like air, water, sunlight, soil, minerals, forests, wild life etc.
Natural resources are of two main types. They are renewable and non-renewable natural resources.
i) Renewable natural resources :-
Those resources which can be replenished in a short period of time like air, water, sunlight, forests etc.
ii) Non-renewable natural resources :-
Those resources which cannot be replenished in a short period of time like minerals (coal, petroleum, natural gas, metals etc.) because they take millions of years to be formed.
Human activities produce a lot of waste materials which are thrown away into the environment. These wastes cause pollution of natural resources like air, water and soil.
he three Rās to save the environment are Reduce, Recycle and Reuse.
i) Reduce :- means using less of natural resources and avoiding
wastage of natural resources.
ii) Recycle :- means the materials like paper, plastic, glass, metals
etc used for making things can again be used for making new things
instead of synthesising or extracting new paper, plastic, glass or
metals.
iii) Reuse :- means using things again and again like the plastic bottles
in which we buy jams, pickles etc can be again used for storing
things in the kitchen.
All the things we use and consume are obtained from
natural resources. Due to increase in population,
industrialisation and urbanisation the demand for natural
resources is increasing and their availability is limited . So
there is a need for proper management of natural resources.
The proper management of natural resources consists of :-
i) Judicious use of natural resources and avoiding wastage
of natural resources.
ii) Long term planning for the use of natural resources so
that it last not only for the present but also for future
generations.
iii) The exploitation of natural resources should not be for
the benefit of a few people but should be distributed
equally for all.
iv) While extracting and using natural resources we should
also plan for the safe disposal of wastes so that no
damage is caused to the environment.
Forests
Importance of forests :-
i) Forests help to preserve biodiversity.
ii) Forests are natural habitats of plants and animals.
iii) Forests provide timber, wood, fuel, medicines, fodder, etc.
iv) Forests help to maintain ecological balance.
v) Forests help to control climate and rainfall.
vi) Forests help to prevent soil erosion and controls floods.
vii) Forests help to maintain the oxygenācarbon dioxide balance in nature.
b) Stake holders of forests :-
People who are associated with forests directly or indirectly are :-
i) People living in and around forests depend on forests for their livelihood.
ii) Industrialists who use the raw materials from forests for manufacturing paper, medicines, furniture etc.
1. Role of individual in preserving
natural resources for their
equitable maintenance
2. Natural resources
ļ§ 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.
ļ§ A commodity is generally considered a natural
resource when the primary activities associated
with it are extraction and purification, as opposed
to creation.
ļ§ 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.
ļ§ A country's economic standing and independence are base on
long-term sales of its natural resources, also known as commodities,
to other nations.
ļ§ Today, population explosion and incresase in manās 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:
ā¢ 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.
ļ§ 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 etcā¦
4. Basing on their availability natural resources are classified into two types.
They are:
1. Renewable resources
2. Non-renewable resources
5. Renewable resources:
ļ§ 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
ā¢ Renewable resources are those
whose supply becomes available for
use at different time intervals and in
which present use does not diminish
future supply.
ā¢ Tree and plant biomass, water and wildlife are a few renewable
ānaturalā resources.
ā¢ Renewable sources have low carbon emissions, therefore they are
considered as green and environment friendly.
6. Non-renewable resources:
ļ§ 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.
ā¢ Non-renewable sources are not environmental
friendly and can have serious affect on our
health.
ā¢ Non-renewable sources will expire some day
and we have to us our endangered resources
to create more non-renewable sources of
energy.
ā¢ Non-renewable sources release toxic gases in
the air when burnt which are the major cause
for global warming.
ā¢ Examples for non renewable resources are fossil fuels, natural gas, oil
and coal.
7. Types of natural resources
Different types of natural
resources are:
ļ¶Forest resources
ļ¶Water resources
ļ¶Mineral resources
ļ¶Food resources
ļ¶Land resources
ļ¶Energy resources
8. Forest resources
Forests are classified into :
ā¢Tropical forests
ā¢Temperate forests
ā¢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
ā¢ Implement afforestation
programmes
ā¢Overgrazing of cattle should be
reduced
ā¢ Control the usage of paper
ā¢Forest conservation act should be
strictly implemented
ā¢ Recycle and buy recycled products.
ā¢When a tree is cut,one plant should
be grown in order to maintain
balance.
ā¢Educate people on ecological value
of tree, reduce use of timber, plant
ā¢Provide alternate fuel to the forest
fringe poor people to reduce
pressure on firewood for daily need.
10. Water resources
Threats to water resources:
ā¢Dumping industrial waste
ā¢Dumping pesticides and
organic waste
ā¢Eutrophication
ā¢Bio magnification
ā¢Thermal pollution
ā¢Oil spills
11. Measures to conserve water resources
ļ§Rain water harvesting must be done.
ļ§ Sewage treatment should be
implemented.
ļ§ Use drip irrigation for shrubs and
trees to apply water directly to the
roots where it's needed.
ļ§ Use a water-efficient showerhead.
They're inexpensive, easy to install,
and can save you up to 750
gallons per month.
ļ§ Look for products bearing
the EPA WaterSense Label
for items that been certified
to save 20% or more without
sacrificing performance.
ļ§ Water-saving steam
sterilizers, for use in
hospitals and health care
facilities.
ļ§Improved water management
practices that reduce or
enhance the beneficial use of water.
12. Mineral resources
ā¢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:
ā¢ Metallic:examples are iron,alluminium,
copper,gold.etc..
ā¢ non-metallic: examples are coal,gypsum,
silica ,limestone.etc..
Threats of mining:
ā¢Disturbance to mantle layer
ā¢Earthquakes
ā¢Tsunami
ā¢Drowning of land
ā¢Deforestation
ā¢Acid mine drainage
13. Conservation methods
ļ§Implementation of bio-mining/leaching
technology.
ļ§Enhanced oil recovery (eor).
ļ§Usage of bio fuels.
ļ§Surface mining control and reclamation act
should be strictly implemented.
ļ§Mining activities should me done under
strict supervision of authorities
ļ§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.:
ļ§Organic farming:it is a process in which both modern and traditional
methods of farming are utilized.
ļ§Mulching:process of adding or layering dry leaves
ļ§Composting:conversion of complex materials into simpler ones with the
help of micro organisms.
ļ§Usage of Green manure.
16.
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
ļ§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.
ļ§Matter that stores energy is called a
fuel.
Energy resources are
Classified into two types.
They are:
ā¢Renewable:solar energy,
wind energy,tidal energy,
geothermal energy etc..
ā¢Non renewable energy:
coal,petrol,diesel.etc..
21. Conservation of energy resources
ā¢CFLs use 60% less energy than a regular bulb. This simple switch
will save about 300 pounds of carbon dioxide a year.
ā¢Change your travel behaviour, think more in terms of public
transportation, if possible, walk or ride your bicycle instead of taking
the car.
ā¢Turn off lights and appliances when you are not using them, use
energy-saving light bulbs.
ā¢Use a microwave instead of a stove to reheat food.
ā¢Use rechargeable batteries instead of disposable batteries.
ā¢Install skylights in the roof or walls to reduce the need for artificial
lighting.
ā¢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.)
ā¢Donāt overload refrigerators; they operate more efficiently when air
circulation is not restricted.
