2. WHAT IS A RESOURCE???
Everything
available in our
environment and
which satisfy our
needs
It should be
1.)
Technologically
accessible
2.) Culturally
acceptable
3.) Economically
feasible
4. RESOURCES-ORIGIN
• Obtained from
Biosphere and have Life
• Examples- Flora, Fauna,
Fisheries, Livestock,
Human Beings
BIOTIC
• All the things which are
Composed of Non
Living Things
• Examples- Rocks,
Metals
ABIOTIC
5. RESOURCES-EXHAUSTIBILITY
Resources on the basis of
Exhaustibility
Renewable
These resources can be
renewed/recycled.
For Example
Solar and Water Energy,
Forests etc.
Further Divided into
Continuous- Water and Wind
Flow-Natural Vegetation and
Wildlife
Non Renewable
These resources cannot be
renewed as they take million
years to form.
For Example
Minerals, Fossil Fuels.
6. RESOURCES-
OWNERSHIP
INDIVIDUAL
• The resources
which are
owned
privately by
individuals.
• Example-
Mobiles,
Land.
COMMUNITY
• The which
resources are
accessible to
all members
of the
society.
• Example-
Public Parks,
Playgrounds.
NATIONAL
• The resources
which
belongs to
the
government.
• Technically all
resources
belong to the
nation.
• Example-
Roads,
Oceanic area
up to 19.2km.
INTERNATIONAL
• The resources
belonging to
international
institutions.
• Example-
Oceanic
resources
beyond 200
nautical miles
of the
EEZ.(Exclusive
Economic
Zone)
7. RESOURCES-STATUS OF
DEVELOPMENT
POTENTIAL
•Resources which are found in a region, but not have been utilized.
•Like Rajasthan and Gujarat have potential of solar and wind energy but not been used for some
reasons.
DEVELOPED
•Resources which are surveyed and their quality and quantity is determined for utilization
•The development of resources depends on technology and level of their feasibility.
•Coal, Petroleum
STOCK
•The resources which have potential to satisfy human needs but there is no technology to access
these are included among Stock.
•Like Water is a compound of Hydrogen and Oxygen which can be used as rich source of energy but
there is technology to use it.
RESERVES
•They are subset of stock which can be use with existing technology but are conserved for the future
generations.
•Like river water is used to a limited consent for generating electricity so that it can be used in future.
8. DEVELOPMENT OF RESOURCES
Development of
Resources
Essential for
future as
resources are
limited in supply
Exploitation
Unequal
Distribution
Ecological
Problem
Scarcity of
resources
Depletion
of resources
9. Rio de Janeiro Earth Summit,1992
• More than 100 heads of states met in Rio de Janeiro in
Brazil, for the first International Earth Summit.
• The Summit was convened for addressing urgent
problems of environmental protection and
socioeconomic development at the global level.
Agenda 21
• It is the declaration signed by world leaders in 1992 at
the United Nations Conference on Environment and
Development (UNCED)
• It aims at achieving global sustainable development.
12. RESOURCE PLANNING
IDENDIFYING
INVENTORY OF
RESOURCES
ECONOMIC AND
TECNOLOGICAL
EVOLUTION
MATCHING
RESOURCE
DEVELOPMENT
PLAN
Resource Planning is
widely accepted
strategy for judicious
use of resources.
It has importance in a
country like India which
has enormous diversity
in resources
HOW IS RESOURCE PLANNING DONE???
13. SOIL AS A RESOURCE
Most important natural resource.
Medium of plant growth and supports different
types of living organism on the earth.
Takes million of years to form soil up to a few
cm in length.
14. FACTORS AFFECTING
FORMATION OF SOIL
Parent Rock Climate Vegetation
Wind
Activity of
Decomposition
Glaciers
Organic and
Inorganic
Materials
Temperature
15. CLASSIFICATION OF SOIL
Colour Thickness
Chemical and
Physical
Properties
Texture-Age
Classification
on the basis
of :-
ALLUVIAL
BLACK
RED
LATTERITE
ARID
FOREST
16. ALLUVIALSOIL
Very Fertile
Formed by the
deposit [Sand and
Silt] brought by the
rivers
Found in Northern
Plains, Coastal
Plains, Deltas of
Rivers
Rice, Wheat,
Cotton, Oil Seed
Rich in Potash and
Lime
Deficiency in
Nitrogen
17. BLACK SOIL
Black in Colour
Known as Regur Soil,
Cotton Soil, Lava Soil
Made up of lava flow
[Breaking down of
igneous rocks]
Found in Maharashtra,
M.P, Chhattisgarh,
Godavari and Krishna
Valleys
Good Capacity to hold
moisture
Rich in Calcium
Carbonate, Potash,
Lime
Deficiency in
Phosphoric Content
Crack occurs when dry Sticky when wet
18. RED AND YELLOW SOIL
Found in Eastern
and Southern part
of Deccan Plateau
Formed by the
denudation of
Igneous and
Metamorphic Rocks
Rice, Pulse, Sugar
Cane
Rich in Iron
Deficiency in
Nitrogen, Humus,
Lime
19. LATTERITE SOIL
Acidic Porous Leaching by
Heavy Rainfall
Found in
Western
Ghats, Shillong
Coffee,
Rubber,
Cashew
Rich in Iron
Deficiency in
Lime, Potash
22. SOIL EROSION
The denudation of the soil cover
and subsequent washing down is
called SOIL EROSION.
• 1.) Human- Deforestation, Over Grazing etc.
• 2.) Natural- Wind, Glacier etc
Due to Human and Natural
Factors
The processes of Soil Formation
and Erosion go on
simultaneously and generally
there is a balance b/w the two.
• 1.) Gully Erosion
• 2.) Sheet Erosion
Types :-
23. Contour Ploughing –
Ploughing around the contour lines to decelerate the flow of
water down the slopes
Terrace Farming –
Cutting out the slopes and making terraces
Strip Cropping –
Strips of grass are left to grow b/w the crops. It breaks up the
force of wind.
Planting Shelter Belts –
Planting lines of trees to create shelter.
