2. What Are Resources?
Anything that can be used to satisfy a need is a
resource.
A resource is a source or supply from which
benefit is produced.
For example: land, minerals, air etc.
3. Value Of A Resource
The purely economic value of a resource is controlled by supply
and demand.
This is, however, a narrow perspective on resources.
There are many things that cannot be measured in money.
Natural resources like forests, mountains etc. are considered
beautiful so they have aesthetic value.
Resources also have an ethical value as well, because it is widely
recognized that it is our moral duty to protect and conserve them
for the future generations.
4. Characteristics of resources
Resources have three main characteristics:
Utility
Quantity(often in terms of availability)
Consumption
And Potential for Depletion and Consumption
6. Biotic resources are those obtained from the
biosphere.
Examples-Forests and their products, animals,
birds and their products, fish.
Other marine organisms.
Minerals such as coal and petroleum are
sometimes included in this category.
7.
8. Abiotic resources comprise non-living things.
For examples include land, water, air and minerals
such as gold, iron, copper, silver etc.
9. Renewable resources are those that can be replenished or
reproduced easily.
Sunlight, air, wind, etc., are continuously available and their
quantity is not affected by human consumption.
Many renewable resources can be depleted by human use, but
may also be replenished, thus maintaining a flow.
Like agricultural crops, take a short time for renewal
Others, like water, take a comparatively longer time.
while still others, like forests, take even longer.
10. On the basis of the stage of development, natural resources may be
called: Potential Resources
Potential resources are those that exist in a region and may be
used in the future.
For example, mineral oil may exist in many parts of India
having sedimentary rocks
But until the time it is actually drilled out and put into use, it
remains a potential resource.
11. Non-renewable resources are formed over very long geological
periods.
Minerals and fossils are included in this category.
Since their rate of formation is extremely slow, they cannot be
replenished once they are depleted.
Out of these, the metallic minerals can be re-used by recycling
them, but coal and petroleum cannot be recycled.
13. On the basis of distribution, natural resources can be classified
into:
Ubiquitous resources- the resources that can be found
everywhere.
For example- air, light, water etc.
Localized-are those that can be found only in certain parts of
the world.
For example-copper and iron ore, thermal power plant etc.
14.
15. Human
beings are also considered to be
resources.
The
term Human Resources can also be
defined as the skills, energies, talents,
abilities and knowledge.
That
are used for the production of goods
or the rendering of services.
16. Sometimes, natural substances become resources only when
their original form has been changed.
Iron ore was not a resource until people learnt to extract iron
from it.
People use natural resources to make buildings, bridges,
roads, machinery and vehicles.
17. Which are known as HUMAN-MADE
RESOURCES. Technology is also a human
made resource.
18.
19. India's inland water resources comprising
rivers, canals, ponds and lakes and marine resources
comprising the east and west coasts of the Indian ocean and
other gulfs and bays
provide employment to nearly 6 million people in the fisheries
sector.
India is rich in certain energy resources which promise
significant future potential - clean / renewable energy
resources like solar, wind, bio-fuels
20. India's major mineral resources include Coal (fourth-largest
reserves in the world)
Iron ore, Manganese, Mica, Bauxite, Titanium ore, Cromite
Natural gas, Diamonds, Petroleum, Limestone and Thorium
(world's largest along Kerala's shores).
India's oil reserves, found in Bombay High off the coast of
Maharashtra, Gujarat, Rajasthan and in eastern Assam meet
25% of the country's demand.
24. India of proven oil reserves as of January 2007, which is the
second-largest amount in the Asia-Pacific region behind
China.
Most of India's crude oil reserves are located in the western
coast (Mumbai High).
India had 38 trillion cubic feet of confirmed natural gas
reserves as of January 2007.
2007.A huge mass of India’s natural gas production comes
from the western offshore regions, particularly the Mumbai
High complex.
The onshore fields in Assam, Andhra Pradesh, and Gujarat
states are also major producers of natural gas.
