Q

Classification of resources

A

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.

resources can be classified in the
following ways -
1. Natural - renewable and non-renewable
2. human - structures and instituions, quantity and quality

  1. Renewable - continous or flow e.g, wind, water and biological
  2. biological - natural vegetation(forests) and wildlife
  3. Non-renewable - recylable and non recyclable

Q

indiscriminate use of resource has led to

A

human beings used them
indiscriminately and this has led to the
following major problems.
* Depletion of resources for satisfying the
greed of a few individuals.
* Accumulation of resources in few hands, which, in turn, divided the society into two segments
i.e. haves and have nots or rich and poor.
* Indiscriminate exploitation of resources has led to global ecological crises such as, global warming, ozone layer depletion, environmental pollution and land degradation.

Q

Define Sustainable development

A

Sustainable economic development means
‘development should take place without
damaging the environment, and development in the present should not compromise with the needs of the future generations.’

The Brundtland Commission Report, 1987 introduced the concept of ‘Sustainable Development’ and advocated it as a means for resource conservation,
which was subsequently published in a book
entitled Our Common Future.

Q

Agenda 21

A

It is the declaration signed by world leaders
in 1992 at the United Nations Conference
on Environment and Development (UNCED),
which took place at Rio de Janeiro, Brazil. It
aims at achieving global sustainable
development. It is an agenda to combat
environmental damage, poverty, disease
through global co-operation on common
interests, mutual needs and shared
responsibilities. One major objective of the
Agenda 21 is that every local government
should draw its own local Agenda 21.

Q

RESOURCE PLANNING

A

Planning is the widely accepted strategy for
judicious use of resources.

There are regions which are rich in certain types of resources but are deficient in some other resources.

There are some regions which can be considered self sufficient in terms of the availability of resources and there are some regions which have acute shortage of some vital resources.

For example, the states of
Jharkhand, Chhattisgarh and Madhya
Pradesh are rich in minerals and coal deposits.

Arunachal Pradesh has abundance of water
resources but lacks in infrastructural
development.

The state of Rajasthan is very well
endowed with solar and wind energy but lacks in water resources.

The cold desert of Ladakh is relatively isolated from the rest of the country. It has very rich cultural heritage but it is deficient in water, infrastructure and some vital minerals.

This calls for balanced resource planning at the national, state, regional and local levels.

Q

Resource Planning in India

A

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.

India has made concerted efforts for
achieving the goals of resource planning right from the First Five Year Plan launched after Independence.

The availability of resources is a necessary
condition for the development of any region, but mere availability of resources in the absence of corresponding changes in technology and institutions may hinder
development.

There are many regions in our
country that are rich in resources but these
are included in economically backward
regions.

On the contrary there are some regions
which have a poor resource base but they are economically developed.

The history of colonisation reveals that
rich resources in colonies were the main
attractions for the foreign invaders. It was
primarily the higher level of technological
development of the colonising countries that helped them to exploit resources of other regions and establish their supremacy over the colonies. Therefore, resources can
contribute to development only when they are accompanied by appropriate technological development and institutional changes. India has experienced all this in different phases of colonisation.

Therefore, in India, development,
in general, and resource development in
particular does not only involve the
availability of resources, but also the
technology, quality of human resources and
the historical experiences of the people.

Q

Conservation of Resources

A

Resources are vital for any developmental activity. But irrational consumption and over-utilisation of resources may lead to socio-economic and environmental problems.

Conservation is judicious and planned use of natural resources for sustainable benefit to the present generation. It also maintains a potential to meet the needs and aspirations of future generations.
To overcome these problems, resource conservation at various levels is important.

This had been the main concern of the leaders and thinkers in the past.

  1. Rio de Janeiro Earth Summit, 1992 was
    convened for addressing urgent problems of
    environmental protection and socioeconomic development at the global level.
  2. the Brundtland Commission Report, 1987. introduced the concept of ‘Sustainable Development’ and advocated it as a means for resource conservation

Q

Mahatma Gandhi

“There is enough for everybody’s need and not for any body’s greed.”

A

“There is enough for everybody’s need and not for any body’s greed.”

He placed the greedy and selfish
individuals and exploitative nature of modern technology as the root cause for resource depletion at the global level. He was against mass production and wanted to replace it with the production by the masses.

Q

LAND DEGRADATION IN STATES

A

Mining sites are abandoned after excavation work is complete leaving deep scars and traces of over-burdening. In states like Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha deforestation due to mining have caused severe land degradation.

In states like Gujarat, Rajasthan, Madhya Pradesh and Maharashtra overgrazing is one
of the main reasons for land degradation.

In the states of Punjab, Haryana, western Uttar
Pradesh, over irrigation
is responsible for land
degradation due to water logging leading to
increase in salinity and alkalinity in the soil.

The mineral processing like grinding of
limestone for cement industry and calcite and
soapstone for ceramic industry generate huge
quantity of dust in the atmosphere. It retards
the process of infiltration of water into the soil
after it settles down on the land. In recent
years, industrial effluents as waste have
become a major source of land and water
pollution in many parts of the country.

Q

Explain four types of resources based on ownership and give one example of each type. (2014)

A

On the basis of ownership, there are four types of resources:

  1. Individual Resources. Resources, which are owned privately by individuals, e.g., farmers own
    pieces of land or houses. Plantation, pasture lands, water in wells are some resources owned by individuals.
  2. Community Owned Resources. These resources are accessible to all the members of the community, e.g., village ponds, public parks, playgrounds in urban areas are accessible to all the residents of that area
  3. National Resources. All the resources within the political boundary of a nation including the territorial water (oceanic area upto 12 nautical miles from the coast) extending into the ocean and resources therein belong to the nation, e.g., all minerals, forests, wildlife, water resources, land etc.
  4. International Resources. There are international institutions which own and regulate some resources, e.g., The oceanic resources beyond 200 km of the Exclusive Economic Zone belong to the open ocean and no individual country can utilise these without the concurrence of international institutions.

Q

three major relief features of India and their respective share in the total area. write the importance of each.

A

Three major relief features:
1. Plains — 43%
(i) provide facilities for agriculture.
(ii) provide facilities for industrial development.
(iii) because of their level, nature and ease of construction, plains support huge population of the country.

  1. Mountains — 30%
    i) ensure perennial flow of some rivers and many rivers rise from them.
    (ii) provide facilities for tourism.
    (iii) are important from ecological point of view, e.g. have lot of forest wealth and wildlife.
  2. Plateaus — 27%
    (i) possess rich reserves of minerals.
    (ii) contain lot of fossil fuels, especially coal.
    (iii) possess rich forest cover.

Q

explain the land-use pattern in India. Why has land under forest not increased much since 1960-61?

A

Land resources are used for the following
purposes:
1. Forests
2. Land not available for cultivation
(a) Barren and waste land
(b) Land put to non-agricultural uses, e.g.
buildings, roads, factories, etc.
3. Other uncultivated land (excluding
fallow land)
(a) Permanent pastures and grazing land,
(b) Land under miscellaneous tree crops
groves (not included in net sown area),
(c) Cultruable waste land (left uncultivated
for more than 5 agricultural years).
4. Fallow lands
(a) Current fallow-(left without cultivation
for one or less than one agricultural year),
(b) Other than current fallow-(left
uncultivated for the past 1 to 5
agricultural years).
5. Net sown area the physical extent of land
on which crops are sown harvested is
known as net sown area.
Area sown more than once in an
agricultural year plus net sown area is
known as gross cropped area.

The land under forests has increased marginally. From 18.11% in 1960-61, it is still only 23.3% which is far lower than the desired 33% as outlined by the National Forest Policy (1952).
Reasons for marginal increase in forest area:

increasing population
technological developments
expansion of agriculture
development of transport and communication facilities
overgrazing
felling of trees

Q

What do you understand by ‘reported area’? What is the reported area of India and why? Give two major reasons.

A

The percentage of total area for which land-use statistics (data) are available, is termed as ‘reported area’.

Total geographical area of India is 3.28
million sq km. Land use data, however, is
available only for 93 per cent of the total
geographical area because the

land use reporting for most of the north-east states except Assam has not been done fully.
Moreover, some areas of Jammu and Kashmir occupied by Pakistan and China have also not been surveyed.

Q

factors which determine the use of land.

A

The use of land is determined both by
1. physical factors such as topography, climate, soil types
as well as
2. human factors such as population
density, technological capability and culture
and traditions etc.

17
Q

“The pattern of net sown area varies greatly from one state to another.”
Or
Name two states having high net sown area and two states having low net sown area. Give two reasons for each.

A

Punjab and Haryana are two states, which have more than 80% of their total area as N.S.A. (Net Sown Area) because:

  1. They are agriculturally rich States because of favourable climatic conditions for the growth of crops and levelled fertile nature of land.
  2. Irrigation facilities are well-developed here.

States with low N.S.A. i.e., less than 10% are Arunachal Pradesh and Mizoram because:

  1. The nature of land is hilly and forested, therefore availability of arable land is less.
  2. Economic backwardness and climatic conditions also do not encourage large scale agricultural activities.
18
Q

Write some measures/ways to solve problems of land degradation. (2014)

A

Measures to conserve land:

Afforestation.
Proper management of grazing to control over-grazing.
Planting of shelter belts of plants.
Stabilisation of sand dunes by growing thorny bushes.
Control of mining activities.
Proper discharge and disposal of industrial effluents and wastes after treatment.
Proper management of waste-lands
Avoid over-irrigation, especially in dry areas.
Avoid overuse of fertilisers and pesticides.

19
Q

Write the main factors responsible for soil formation.

A

Soil is a living system. It takes millions of years to form soil up to a few centimeters in depth.
Factors responsible for soil formation are:

Parent rock or bed rock on which the soils are formed, disintegrate and decompose under the process of weathering and erosion.

Climate: It determines the rate of weathering.

Relief, vegetation, other forms of life and time are other important factors in the formation of soils.

Various forces of nature such as change in temperature, actions of running water, wind and glaciers, activities of decomposers etc. also contribute to the formation of soil.

Chemical and organic changes which take place in soil, also play a role in its formation.

20
Q

On what basis are soils classified into different types?

A

Basis of classification of soils:

Colour
Thickness
Texture
Age
Chemical and physical properties
Factors responsible for soil formation.

21
Q

Alluvial Soils

A

This is the most widely spread and important soil. In fact, the entire northern plains are made of alluvial soil. These have been deposited by three important Himalayan river systems – the Indus, the Ganga and the Brahmaputra.

The alluvial soil consists of various proportions of sand, silt and clay. As we move inlands towards the river valleys, soil particles appear somewhat bigger in size. In the upper reaches of the river valley i.e. near the place of the break of slope, the soils are coarse. Such soils are more common in piedmont plains such as Duars, Chos and Terai.

Apart from the size of their grains or
components, soils are also described on the
basis of their age. According to their age
alluvial soils can be classified as old alluvial
(Bangar) and new alluvial (Khadar). The
bangar soil has higher concentration of kanker nodules than the Khadar. It has more fine particles and is more fertile than the bangar.

Alluvial soils as a whole are very fertile.
Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.

Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated.

Soils in the drier areas are more alkaline and can be productive after proper treatment and irrigation.

22
Q

Black Soil

A

These soils are black in colour and are also
known as regur soils. Black soil is ideal for
growing cotton and is also known as black
cotton soil.

It is believed that climatic condition
along with the parent rock material are the
important factors for the formation of black
soil.

This type of soil is typical of the Deccan
trap (Basalt) region spread over northwest
Deccan plateau and is made up of lava flows. They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh and extend in the south east direction along the Godavari and the Krishna valleys.

The black soils are made up of extremely
fine i.e. clayey material. They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents.

They develop deep cracks during hot weather, which helps in the proper aeration of the soil. These soils are sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.

23
Q

Red and Yellow Soils

A

Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau.

Yellow and red soils are also found in parts of Odisha, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats.

These soils develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form.

24
Q

Laterite Soil

A

Laterite has been derived from the Latin word ‘later’ which means brick.

The laterite soil develops under tropical and subtropical climate with alternate wet and dry season.

This soil is the result of intense leaching due
to heavy rain. Lateritic soils are mostly deep
to very deep, acidic (pH<6.0), generally
deficient in plant nutrients and occur mostly
in southern states, Western Ghats region of
Maharashtra, Odisha, some parts of West
Bengal and North-east regions.

Where these soils support deciduous and evergreen forests, it is humus rich, but under sparse vegetation and in semi-arid environment, it is generally humus poor. They are prone to erosion and degradation due to their position on the landscape. After adopting appropriate soil conservation techniques particularly in the hilly areas of Karnataka, Kerala and Tamil Nadu, this soil is very useful for growing tea and coffee.

Red laterite soils in Tamil Nadu, Andhra Pradesh and Kerala are more suitable
for crops like cashew nut.

25
Q

Arid Soils

A

Arid soils range from red to brown in colour. They are generally sandy in texture and saline in nature. In some areas the salt content is very high and common salt is obtained by evaporating the water.

Due to the dry climate, high temperature, evaporation is faster and the soil lacks humus and moisture. The lower horizons of the soil are occupied by Kankar because of the increasing calcium content downwards. The Kankar layer formations in the bottom horizons restrict the infiltration of
water. After proper irrigation these soils
become cultivable as has been in the case of western Rajasthan.

26
Q

Forest Soils

A

These soils are found in the hilly and
mountainous areas where sufficient rain
forests are available. The soils texture varies
according to the mountain environment
where they are formed. They are loamy and
silty in valley sides and coarse grained in
the upper slopes. In the snow covered areas of Himalayas, these soils experience
denudation and are acidic with low humus
content. The soils found in the lower parts of the valleys particularly on the river terraces and alluvial fans are fertile.

27
Q

What is soil erosion? Write the main causes of soil erosion. Explain three types of soil erosion mostly observed in India.

A

The denudation of the soil cover and
subsequent washing down is described as soil erosion.

The process of soil formation and erosion goes on simultaneously and generally there is a balance between the two. This balance is sometimes disturbed, leading to soil erosion. The main activities like deforestation, overgrazing, construction and mining and also natural agents like wind, running water and glacier are the main causes of soil erosion.

  1. The running water cuts through
    the clayey soils and makes deep channels as gullies. The land becomes unfit for cultivation and is known as bad land. In the Chambal basin such lands are called ravines.
  2. Sometimes water flows as a sheet over large areas down a slope. In such cases the soil is washed away. This is known as sheet erosion.
  3. Wind blows loose soil off flat or
    sloping land known as wind erosion
28
Q

Write four methods of soil conservation.

A

Methods of soil conservation:

Contour ploughing By ploughing along the contour lines, water will not run down the slopes.
Terrace cultivation Steps can be cut on the slopes to make terraces. This restricts erosion.
Strip cropping Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks the force of the wind.
Planting of shelter belts The planting of trees in rows to create shelter also breaks the force of the wind and restricts soil erosion.
Shelter belts have helped in the stabilisation of sand dunes and deserts.
