resources and development Flashcards
what is a resource
Everything available in our environment which can be used to satisfy our needs, is called a resource. It should be technologically accessible, economically feasible and culturally acceptable. Only then, it can be termed as a ‘Resource’. Examples: minerals, forests
explain the interdependance between nature, humans and tech
The process of transformation of things available in our environment involves an inter- dependent relationship between nature, technology and institutions. Human beings interact with nature through technology and create institutions to accelerate their economic development.
humans are essential components of resources. how? or are resources free gifts of nature?
Human beings themselves are
essential components of resources. They
transform material available in our
environment into resources and use them.
These resources can be classified in the
following ways–
(a) On the basis of origin – biotic and abiotic
(b) On the basis of exhaustibility – renewable
and non-renewable
(c) On the basis of ownership – individual,
community, national and international
(d) On the basis of status of development –
potential, developed stock and reserves.
Classify resources on the basis of origin.
Biotic Resources are obtained from the biosphere and have life.
Eg: Human beings, flora and fauna, fisheries, livestock etc.
Abiotic Resources: All those things which are composed of non-living things are called abiotic resources.
Eg: rocks and metals.
Give one difference between renewable and non-renewable resource
renewable resources
1) the resources that can be renewed by reproduction are called renewable resources.
2) Renewable resources are inexhaustible.
3) Renewable resources are not affected by the human activities.
4) All biotic resources are renewable.
5) For example: air and water.
non-renewable resources
1)the resources that are present in fixed quantities are called non-renewable resources.
2) Non-renewable resources are exhaustible.
3) Non renewable resources are affected by human activities.
4) Some abiotic resources are non-renewable.
5) For example- fossil fuels and minerals.
Renewable resources are resources that can be produced naturally and nonrenewable resources are resources that cannot be replaced.
what are the types of renewable resources
The renewable resource may further be divided into continuous or flow.
what are the types of non renewable resources
Some of the resources like metals are recyclable and some like fossil fuels cannot be recycled and get exhausted with their use.
List the types of resources classified on the basis of its ownership
Individual Resources are owned privately by individuals. In villages people own lands whereas in urban areas people own plots, houses and other properties.
Eg: Plantation, pasture lands, ponds, water in wells etc.
Community Owned Resources are accessible to all the members of the community.
Eg: Grazing grounds, burial grounds, public parks, picnic spots, playgrounds etc.
National Resources are owned by a nation or country.
Eg: Roads, canals, railways etc.
International Resources are regulated by international institutions.
Eg: space, oceanic resources
what is territorial water
All the minerals, water resources, forests, wildlife, land within the political boundaries and oceanic area up to 12 nautical miles (22.2 km) from the coast termed as territorial water and resources therein belong to the nation.
India has the right to mine which mineral
India has got the right to
mine manganese nodules from the bed of
the Indian Ocean from that area which lies
beyond the exclusive economic zone.
List the types of resources classified on the basis on status of development
Potential Resources are the resources which are found in a region but have not been utilised.
Eg: Rajasthan and Gujarat have enormous potential for the development of wind and solar energy, but have not been developed properly.
Developed Resources: Resources which are surveyed and their quality and quantity have been determined for utilisation.
Materials in the environment which have the potential to satisfy human needs but human beings do not have the appropriate technology to access these, are called Stock.
Eg: Hydrogen can be used as a rich source of energy. But we do not have advanced technology to use it.
Reserves are the subset of the stock, which can be put into use with the help of existing technical ‘know-how’ but their use has not been started. These can be used for meeting future requirements.
Eg: Water in the dams, forests etc. is a reserve which can be used in the future.
factors that development depends on-
The development of resources depends on technology and level of their feasibility.
Distinguish between stock and potential resources. Give one example of each
(i) Stock:
(a) They are found in the environment.
(b) They are not accessed due to the lack of technology. (c) Example: hydrogen and oxygen, can be used as a rich source of energy.
(ii) Potential resources:
(a) They are found in a region.
(b) They have not been utilized or developed. (c) Example: Rajasthan and Gujarat have enormous potential for the development of wind and solar energy
Differentiate between stock and reserve stating two points of differences.
stock is the resources for which presently, we don’t have any technology to extract them.
Reserve resources are those which we are not extracting them at present in spite of technological availability.
Eg: Hydrogen can be used as a rich source of energy Eg: Water in the dams
What has indiscriminate use of resources led to-
- depletion of resources
- accumulation of resources- dividing society into rich/poor
- global ecological crisis-
a. global warming
b. ozone layer depletion
c. environmental pollution
d. land degradation - lesser availability of fossil fuels or conventional sources of energy for the future generations .
- soil erosion , increase in salinity of soil , and decrease in it’s fertility.
