RESOURCES AND DEVELOPMENT
Chapter
01
RESOURCE: Anything which can
be used for satisfying the human needs, which is technologically accessible, economically
feasible and culturally acceptable can be termed as Resources.
TYPES OF RESOURCES:
Resources can be classified on
different bases; into following types:
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
Classification of Resources:
On the basis of Origin
- Biotic Resources: All living organisms in our environment
are called biotic resources. For example,human beings,livestock,flora and fauna etc.
- Abiotic Resources: All non-living things present in our
environment are termed as abiotic resources. For example – earth, air,
water, metals, rocks, etc.
Classification of Resources:
On the basis of Exhaustibility:
- Renewable Resources: Resources that can be replenished after
a short period of time are called Renewable Resources. For example –
agricultural crops, water, forest, wildlife, etc.
- Non-renewable Resources: Resources which takes million years of
time to replenish are called non-renewable resources. For example – fossil
fuel.
Classification of Resources:
On the Basis of ownership:
- Individual: Resources owned by individuals are
called Individual Resources. For example – land owned by farmers, house,
etc.
- Community: Resources owned by community or society
are called Community Owned Resources. For example – Graveyard, grazing
land, ponds, burial grounds, park, etc.
- National Resources: Resources owned by Individual Nations
are called National Resources. For example – Government land, Roads,
canals, railway, etc.
- International Resources: Resources regulate by International
bodies are called International Resources. For example – Ocean and sea
beyond 200 km of the Exclusive Economic Zone and is called open sea or
ocean. No individual country can utilize these resources without the
permission of International bodies.
Classification of Resources:
On the basis of Status of Development:
- Potential Resources: Resources which are found in a
particular region, but not yet used properly. For example – Rajasthan and
Gujarat receive plenty of solar energy and have plenty of wind energy, but
use of these resources so far has not been developed properly.
- Developed Resources: Resources which are developed and
surveyed for utilization and are being used in present time are known as
Developed Resources.
- Stock: Resources that are available, but we do
not have proper technology to used them are called Stock. For example –
water is made of oxygen and hydrogen, which can be used as fuel, but
because of lack of proper technology these are not being used.
- Reserves: Resources which are available and the
know how to use them is also present but they are yet to be used are called
Reserves. For example – river water which is not used to generate
electricity.
DISCRIMINATE USE OF RESOURCES
Resources are vital for human
beings. But indiscriminate use of resources is creating many problems.
Examples:
- Accumulation of resources
in only few hands leaves others unsatisfied.
- Indiscriminate use of
resources is creating many problems around the world, such as global
warming, ecological crisis, disturbance in ozone layer, etc.
- Thus, equal distribution
of resources becomes necessary for sustainable development.
SUSTAINABLE DEVELOPMENT:
Development which takes
place without damaging the environment and compromising with needs of future is
called sustainable development.
Keeping the view of justified
use of resources and sustainable development, the Earth Summit was organized in
1992 in Rio de Janeiro(Brazil) in which more than 100 state heads agreed with Agenda
21 for the sustainable development and proper use of resources.
AGENDA 21 is an agenda to combat
environmental damage, poverty, disease, etc. through global co-operation on
common interests, mutual needs and shared responsibilities.
RESOURCE PLANNING:
Resource planning is the
judicious use of resources. Resource planning becomes more important in a
country like India, where resources are not distributed properly.
For example;
many states are rich in mineral and deficient in other resources, such as
Jharkhand is rich in minerals, but there is problem of drinking water and other
facilities, Arunachal Pradesh has plenty of water but lack of other development
because of lack of resources.
These types of discrimination can be reduced or completely vanished with proper planning of judicious use of
resources.
RESOURCE PLANNING IN INDIA:
Resources can contribute in
proper development only with a good planning keeping the technology, skills and
institution in mind.
Resource Planning in India is
one of the most important goals right from its first Five Years Plan. Following
are the main points of Resource planning.
THREE STAGES OF RESOURCE PLANNING
Resource planning is a complex process which involves :
(i) Identification and inventory of resources across the regions of the country. This involves surveying, mapping and qualitative and quantitative estimation and measurement of the resources.
(ii) Evolving a planning structure endowed with appropriate technology, skill and institutional set up for implementing resource development plans.
(iii) Matching the resource development plans with overall national development plans.
CONSERVATION OF RESOURCES
Overuse of resources creates
many socio-economic problems. Many leaders and thinkers have been advocating
for the judicious use and conservation of resources. Gandhiji told “There
is enough for everybody’s need and not for any body’s greed.” He
thought that exploitative nature of modern technology is the root cause for
depletion at global level. He believed in the production by masses and not in
the mass production.
Thus, conservation of resources
at various levels becomes most important. Resources can be conserved only with
their judicious use.
LAND RESOURCES:
Land is one of the most
important natural resources. Land supports our life system. Thus, careful
planning of use of land resource is necessary. India comprises of many types of
land. These are mountains, plateau, plains and islands.
- Mountains: About 30% of land area in India is in
the form of mountain. Mountain supports the perennial flow of rivers,
which carry fertile soils, facilitate irrigation and provide drinking
water.
- Plain: About 43% of land area in India is in
the form of plains. Plains provide facilities for agriculture, building of
industries and houses, etc.
- Plateau: About 27% of land in India is in the form of plateau which provides many types of minerals, fossil fuels and forest.
LAND UTILIZATION: PATTERNS OF
USE OF LAND RESOURCES
- Forests
- Land not available for
cultivation: There are two types of land which are not used for
agriculture purpose. These are:
- Barren and waste land
- Lands used for
buildings, roads, factories, etc. i.e for non-agriculture purpose.
- Other uncultivated land
(excluding fallow land)
- Permanent pastures and
grazing land,
- Land under miscellaneous
tree crops groves (not included in net sown area),
- Culturable waste land
(left uncultivated for more than 5 agricultural years).
- Fallow lands
- Current fallow-(left
without cultivation for one or less than one agricultural year),
- Other than current
fallow-(left uncultivated for the past 1 to 5 agricultural years).
- Net sown area: Area which
is sown at least once in a year is called net sown area.
- Gross cropped area: Area sown more than once in an agricultural year plus net sown area is known as gross cropped area.
LAND USE
PATTERN IN INDIA:
Pattern of
use of land depends upon physical and human factors both. Climate, topography,
type of soil, etc. are considered as physical factors while population,
technology, skill, population density, tradition, capability, etc. are
considered as human factors.
India has total 3.28 million square kilometer land used data. But
only 93% of land of total geographical area is available. This is because land
used data has not been collected for the north eastern states except Assam and
the land occupied by Pakistan and China has not been surveyed because of many
unavoidable reasons.
The land under permanent pasture is decreasing, this will create
the problem for grazing. The total net sown are (NSA) is not more than 54%
including land other than fallow land. Land other than fallow land is either of
poor quality or too costly to cultivate, these lands are cultivated only once
or twice in two or three consecutive years.
The pattern of net sown area varies widely from state to state.
Where net sown area is 80% in state like Punjab, it is only 10% in the state of
Arunachal Pradesh, Mizoram, Manipur and Andaman and Nicobar Island. Such
difference is creating lot of discrimination.
According to National Forest Policy (1952), the forest should be
33% of total geographical area, which is essential to maintain ecological
balance. But the forest area in India is far less than desired measures. This
is because of illegal deforestation and development which cannot be overlooked,
such as construction of roads and building, etc. On the other hand, a large
population which is dwelling at the fringe of forest depends upon the forest
and its produce, resulting in the reduction of forest area.
Moreover, continuous use of land over a long period without taking
measures to conserve and manage, degrade them. This has resulted in
repercussion in society and creating serious problem to environment.
LAND AS
RESOURCE
Our past generation left land
for us without exploiting them too much and it is expected from us too. We fulfill most of our needs from land, such as food, clothing, shelter, drinking water,
etc. But in past few decades the quality of land is degrading fiercely because
of human activity. Many human activities aggravated the natural forces which
are, in turn, degrading the land resources also.
Presently, about 130 million
hectare of land is reported under degraded land(waste land) in India, in which about 28% of
land belongs to forest and about 56% is water eroded area. Rest degraded land
is because of over deposition of salinity and alkalinity. Overgrazing, mining,
deforestation, division of lands in small area because of family feuds, etc.
are some of the major causes of degradation of land.
Because of mining in the
states of Jharkhand, Chhattisgarh, Orissa and Madhya Pradesh; lands are left
abandoned without proper treatment after the completion of mining works. This
has resulted in the form of deep scars and traces. Along with mining,
deforestation in these states has degraded the land very fast.
In the states of Uttar
Pradesh, Punjab, Haryana, over irrigation causes water shortage and increase in
salinity and alkalinity due to water logging.
In Bihar, Assam, Arunachal
Pradesh, land is degraded because of flood.
States, in which minerals
processing, such as grinding of lime stone, manufacturing of cement, etc.
produce huge quantity of dust. These dusts prevent the percolation of water
because of deposition on the ground and it is responsible for degradation of
land.
The degradation of land
creates many problems, such as flood, decrease in yield, etc. which leads to
decrease in GDP and country has to face economic problems.
MEASURES TO CONSERVE THE LAND
RESOURCES:
Degradation of land can be
prevented by taking following measures:
- Afforestation
- Proper management of grazing.
- Stabilization of sand dunes by plantation of thorny
bushes.
- Proper management of waste lands.
- By proper irrigation.
- By proper harvesting.
- Control over mining activities.
- Proper management of land after completion of mining
work.
- Discharge of industrial waste and effluents only
after proper treatment.
- Plantation of trees along the road sides.
- By preventing deforestation.
SOIL AS A NATURAL RESOURCE:
Soil is one of the most
important natural resources. Soil supports the growth of plants. Soil is the
natural home of many living organism, such as ants, rats, snakes, and many
insects.
Formation of Soil: It takes thousands of
years to form even 1 cm of soil. Soil is formed by the weathering process of
the rocks. Various natural forces, such as temperature, running water, wind,
etc. along with many physical and chemical changes are equally important in the
formation of soil formation.
CLASSIFICATION OF SOIL:
Soil is categorized in many
types on the basis of texture, colour, age, chemical properties, etc. India is
a vast country which comprises of many types of land. Thus, many types of soils
are found in different regions in India.
ALLUVIAL SOIL- 45.6%
Availability: Alluvial soil is found
near the river or plains formed by rivers. Alluvial soil is considered
relatively younger in age. In India, alluvial soil is found in the north
eastern plain where Ganga, Yamuna, and Brahmaputra flow. Alluvial soil is
deposited by river system. Entire northern plain is made of alluvial soil.
Alluvial soil is also found in
eastern coastal plains near the Mahanadi, the Krishna, the Godavari and the
Kaveri rivers.
Nature: Alluvial soil is very
fertile, thus plains of Ganga, Brahmaputra, Yamuna, etc. are densely populated.
Alluvial soil is the mixture of various proportions of silt, sand and clay.
Alluvial soils differ in the size of their particles at the area of break of
slope.
Apart from the size of
particles of grains, soils are also classified on the basis of their age. The
older alluvial soil is known as Bangar and new alluvial soil or Khadar. New
alluvial soil has more concentration of coarse grains while Old alluvial soil
has plenty of fine particles.
Alluvial soil is rich in potash,
phosphoric acid and lime. Because of presence of these chemicals alluvial soil
is good for the growth of sugarcane, paddy, wheat, maize, and pulses.
BLACK SOIL- 16%
Availability: Because of black colour,
this type of soil is called black soil. It is also known as Regur Soil. Black
soil is found in the north west deccan plateau. It is found in the plateau of
Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chattisgarh and extent along
with the valley of Krishna and Godavari Rivers.
Nature: Black soil has high
concentration of fine particles and thus can hold moisture for long time. It
contains calcium, potassium, magnesium and lime. Black soil is suitable for the
growth of cotton, but many other crop are grown in the area of black soil.
RED AND YELLOW SOIL- 10.6%
The soil looks red due to
presence of iron in crystalline or metamorphic rocks. When the soil look yellow
when it occurs in dehydrated form. Red soil is present in the eastern and
southern parts of the Deccan Plateau. Red soil is also found in Orissa,
Chhattisgarh, on the southern part of the Gangetic plains and along the piedmont
zone of the Western Ghats.
LATERITE SOIL- 7.2%
Laterite soil is formed in
regions which get high rainfall with high temperature. This causes leaching of
the soil and microorganisms are killed during the process. Due to this,
laterite soil does not contain humus or contains very low amount of humus. This
soil is mainly found in Kerala, Karnataka, Tamil Nadu, Madhya Pradesh and in
hilly areas of Odisha and Assam. This soil can be made cultivable with heavy
dose of manures.
ARID SOIL OR DESERT SOIL- 4%
Arid soil is found in those
areas which receive scanty rainfall. Due to high temperature, evaporation is
faster in these regions. The soil has a high content of salt. Arid soil can be
made cultivable with proper treatment. Arid soil is present in Rajasthan and
Gujarat.
FOREST SOIL OR MOUNTAIN SOIL -8%
The forest soil is found in
hilly areas. The soil in upper parts is highly acidic because of denudation. The
soil in the lower part is highly fertile.
SOIL EROSION AND SOIL
CONSERVATION
Removal of top soil is called
soil erosion. Intense farming, grazing, construction activities and other human
activities; along with deforestation have led to soil erosion. Soil erosion; if
not checked in time; can even lead to desertification.
Causes of Soil Erosion
1 ) Natural ways of Soil erosion: Wind, glacier and water lead to soil erosion.
2 )Human activities: Deforestation, over-grazing, construction and mining etc., contributes in soil erosion.
Measures to control Soil erosion:
→ Strip cropping
→ Planting shelter belts
→ In the hilly areas, using contour ploughing and terrace farming.
Soil conservation is important
to prevent soil erosion. Soil conservation can be done by many methods.
Afforestation is the main method because trees hold the topsoil in place.
Terrace farming and shelter belt planting also help in soil conservation.
