Geography Ch-1 Resources Notes
Geography Ch-1Resources
Resource: Meaning
*Anything that can satisfy our needs is called resource.
Water quenches our thirst, electric bulb gives us light ,we cultivate crops in soil. Soil water electric bulb satisfy our needs so these are resources.
*Resource
are useful substances as they have utility and value.
*Utility
and value makes anything resource .
*Utility
means usefulness. It means satisfaction that someone gets from consuming goods
.
*Value means worth. Resources may have economic value, social or aesthetic value.
*Time and technology are two important factors that can change substances into resources.
Eg. Land, soil, water, silicon, gold and
silver all are useful as they all satisfy our various needs. These all are
economically valuable, so these all are resources.
*Resources are compulsory for human survival
and development.
Classification of resources
Resources are classified
into three types
*Natural
*Human
*Human made resources
Natural resources
*All
resources that are obtained from the nature
*These are the free gifts of nature. Ex. Fish, water
Human resource
*People who create the valuable resources from the
nature. human resource include quantity and quality of human beings.
People themselves are the
most important resource. It is their ideas, knowledge, inventions and discoveries that lead to the
creation of more resources. Ex. Fire , wheel
Importance
*Human resource can make the best use of natural
resources . human resource use their knowledge and skills to convert natural
resources into valuable resources.
#Man made resources
Resources that are created by the humans from the nature .
By using their knowledge and skills humans modify the
natural resources and convert them into
man made resource . Ex. Books , Computers
Types
of natural resources
Natural resources can
be classified in the following ways:
(a) On the basis of origin:
(i) Biotic
(ii) Abiotic
(b) On the basis of exhaustibility(Stock ):
(i) Renewable
(ii) Non-renewable
(c) On the basis of Distribution:
(i) Ubiquitous
(ii) Localised resources
(d) On the basis of status of development:
(i) Potential
(ii)
Actual
# Origin
On the basis of the
origin resources can be
Biotic and Abiotic
Biotic
Resources that are obtained from the living
things .
These are also called
living resources because these resources are obtained from living being.
*Some of these
resources are renewable.
*Eg. Fish, human, tree , birds , animals.
Abiotic –
*Resources that are
obtained from non living things .
*They are also known
as inorganic resources.
*They occur as solid,
liquid or gaseous materials on the earth and in its atmosphere.
*Most of them are
non- renewable but some are recycled.
Eg: rocks , air, water , land or soil.
Types of natural resources
#Development
On the basis of the
development resources can be actual & potential
*Actual resources
*resources
that are in use whose quantity and quality are properly known at present
*We have
knowledge and skills to utilize these resources.
*These
resources are also called developed resources
*Potential Resources
*
Resources which are not developed yet due to lack of technology.
*Human
beings do not have the appropriate technology to access these resources.
*These can
be used in future .we don’t know the quantity and quality of these resources.
*They are
either not easily accessible or not properly developed for present use
*Ex-
Producing hydrogen fuel from sea water
*Potential
of wind and solar energy in Rajasthan
#Distribution
* On the basis of the distribution
resources can be
Ubiquitous & localised resources
Ubiquitous
*Resources which are found everywhere on
the earth.
* air soil and water all are the ubiquitous resources.
Localised
Resources that are found at certain
places.
These resources are unevenly distributed
across the world
Copper , iron gold, diamond are the examples
of localized resources.
Categories
# Stock
On the basis of the
stock resources can be
Renewable & Non
Renewable
Renewable –
*Resources
which can be renewed or reproduced by physical, chemical and mechanical
processes
*They
get renewed over a short period of time.
*They
are unlimited and are not exhausted.
*These
are further divided into continuous or flow and biological
These
resources are generally available throughout the world.
Eg: water, wind , forest, wildlife, solar energy.
Non renewable –
*Resources
which cannot be renewed or reproduced.
*They
take millions of years to form .
*They
are limited in their availability and can not
Be exhausted
*These
are divided into recyclable and non recyclable.
*These
resources are generally unevenly distributed on the earth.
Eg:
minerals and fossil fuels.
Conservation of resources
*Using resources carefully and giving them time to get
renewed is called resource conservation.
*It is a Planned and careful utilization of resources for
sustainable development.
*it means
using the available resources judiciously saving and protecting them from
degradation
Preservation
means protecting
Ways
to conserve resources
There are many ways of conserving resources.
*We can conserve resources by reusing , recycling and
reducing the consumption of resources
*We should not damage and pollute our natural resources
*all uses of renewable resources are sustainable so we
should promote renewable sources of energy
We
should conserve the diversity of life on the earth. plant trees forest water
soil conservation
Sustainable Development
Development of resources without damaging the environment
to meet the needs of present & future generations is called sustainable
dev.
This promotes sustainable economic, social, environmental
growth.
The three pillars of sustainable development are
1. Economic growth
2. Environmental protection
3. Social inclusion
It is the
development across all the economic , social sectors rural and urban areas.
Importance – sustainable development is important because
* if we misuse or pollute our natural resources a time
would come when the world would be without resources.
*Its
in everyday news as the world is coping with climate change, biodiversity loss
, resource conflicts , and scarcity,
*This
brings the ecological balance, development and peace and improves the quality
of human life.
Some Principles of
Sustainable Development
*Respect and care for all forms of life
*Improve the quality of human life
*Conserve the earth’s vitality and diversity
*Minimise the depletion of natural resources
*Change personal attitude and practices toward the
environment
*Enable
communities to care for their own environment
