CHAPTER 1: RESOURCES
AND DEVELOPMENT
Remember These Points
- Anything
available in the environment and can be used to satisfy the needs of human
being is called as resource, e.g. water, land, air, minerals, wildlife
etc.
- Leaching is a
process which takes place in high temperature and rainfall area. In this
process minerals of the soil are dissolved into the rainwater and they
move down in the soil. Laterite soil is formed by this process.
- Black soil is
also called as ‘regur soil’.
- Manganese
nodules are extracted from Indian Ocean.
- Full form of
UNCED is United Nations Conference on Environment and Development.
- Rajasthan has
abundant solar and wind energy potential.
- Earth Summit
was held in Rio de Jeniro [Brazil] in 1992.
- The book
written by Schumacher is ‘Small is Beautiful’.
- Black soil is
formed by weathering of lava rocks.
- Red soil is
formed by weathering of igneous rocks. It looks red due to iron-oxide.
- Land degraded
by gully erosion in Chambal River basin is called ‘Ravines’ or ‘Bad Land’.
Types or Classification of Resources
On the basis of origin:
- Biotic: Those
resources which has life are called biotic resources e.g. plants, trees,
animals etc.
- Abiotic: Those
resources which do not have life are called as abiotic resources e.g.
land, water, minerals etc.
On the basis of exhaustibility:
a) Renewable [Forest, Wildlife, Water]
b) Non-Renewable [Metals, Fossils Fuels]
On the basis of ownership:
a) Individual [land, plot, well, pond]
b) Community [Grazing land, burial ground, park]
c) National [Minerals, Forest, Rivers]
d) International [EEZ – Ocean up to 200 km]
On the basis of development:
- Potential
Resources: Resources which are found in an area but not have been
utilized. For example, Rajasthan and Gujurat has enough potential to
produce solar energy due to cloudless sky and more temperature.
- Developed
Resources: When resources found in a region are surveyed by engineer and
their quality and quantity are determine for utilization, it is called developed
resource. Technology and capital help in development of resources.
- Stock
Resources: Material found in our environment can satisfy many of our need
but they are not used because of lack of appropriate technology. For
example, water has hydrogen, a good source of energy, but due appropriate
technology water is not being used as fuel.
- Reserve
Resources: Reserve is those parts of stock which can be utilized using
existing technology. But these resources are not being used and they have
been left for future generation. They are called reserve.
Sustainable Development: Development without damaging the environment is
called as sustainable development. This development meets the demands of
present generation as well as future generations.
Earth Summit and Agenda 21: Earth Summit is an international conference on
environment. It was held in Rio de Jeniro [Brazil] in 1992. In the conference
leaders of the words discussed about sustainable development and they adopted
21 points policy which is called ‘Agenda 21’.
Resource Planning and Its Steps
Resource planning is method to use the resources in optimum way so that
maximum benefit should reach to maximum people. Resource planning also means
avoiding wastage, misuse and overuse of resources. There are three steps for
resource planning.
a) Identification and inventory of resources by surveying
and mapping
b) Evolving a planning structure to use the resources
with appropriate technology
c) Matching resource development plan with national
development plan
Need and Methods of Conservation of Resources
Father of the nation – Mahatma Gandhi – said that “There is enough for
everybody’s need and not for anybody’s greed”. We should conserve resources for
following reasons.
a) Resources are not found everywhere. They are unevenly distributed.
b) Resources are limited. Many of the resources are
non-renewable.
c) Resources should be conserved for reducing all kinds
of pollution.
d) Resources are also conserved for ‘sustainable
development’.
e) Conservation is needed to protect natural heritage.
Methods or measurements for resource conservation are as under:
a) Wastage, misuse and overuse of resources should be
avoided.
b) Renewable resources should be used more e.g. solar
energy, wind energy etc.
c) Older technology should be replaced with newer, modern
and efficient technology.
d) Awareness should be created among the people.
e) Govt. should pass strict laws for establishment and
location of industries.
f) Used items should be recycled using new technology.
Land Use and Its Category
Land is used for various purposes in a country. India has vast land
resource. Total area of our country is about 3.28 million sq. km. India ranks 7th
in the world in term of size. But most of parts are covered by either mountain
or plateau. India has only 43% plain where agriculture is possible. Mountains
are good sources of biotic resources where varieties of minerals are found in
the plateau. There are 5 categories under land use.
- Forest
- Land not
available for cultivation
- Other
uncultivated land
- Fallow land
- Net sown area
§ Land not available for cultivation includes barren land, waste land and land which is
used for building, roads, parks, factories etc.
§ Fallow land is that land which is left uncultivated by the farmer. Farmer leaves
some land to give rest to the land. Lands are also left fallow due low
rainfall, lack of capital or seeds etc. Fallow land for one or less than one
year is called Current Fallow. If land is left fallow for more than one but
less than five years it is called as Other Fallow land.
§ Net sown area is the actual land on which agriculture is done. Some parts of net sown
area is used more than one time in a single agricultural season. When this land
is added with net sown area, it is called gross sown area or gross cropped
area.
Land Degradation and Its Causes
Lowering the quality of land up to such an extent that the land become
unfit for any use, it is called as land degradation. About 130 million hectare
of lands are degraded in India. Following are the causes of land degradation.
a) Deforestation – cutting of trees and forest
b) Erosion by rain water and wind
c) Water logging in low lying area
d) Increasing salinity [salt] due to over irrigation
e) Dumping of urban and industrial waste on valuable land
f) Mining and quarrying activities for extracting
minerals
Soil, Its Formation & Factors Affecting Soil
Formation
Meaning of Soil: It is an important
an renewable resource. It is upper part of the crust which is loose and
fragmented. It has air, water and minerals contents and it support growth of
plants. Bacteria and other small organisms are also found in the soil which
makes it more fertile.
Formation of Soil: Soil is formed by
weathering and erosion of rocks. Temperature and rainfall breaks down the rock
into smaller parts. After mixing of water and minerals in these sediments, it acquires
the form of soil. Following factors affect soil formation.
Factors Affecting Soil Formation
a) Parent Rocks: It determined the colour, texture and
mineral contents in soil
b) Climate [Rainfall and Temperature]: It determines rate
of weathering and erosion of rocks.
c) Topography [Slope]: On higher land thin layer of soil
is found, while in the lower valley thick deposition of alluvium is found.
d) Vegetation [Plants and Trees]: They add organic matter
[Humus] to the soil.
e) Time: Older soils are generally more fertile than
newer soil.
Soil Erosion and Methods of Soil Conservation
Soil Erosion: Removal of top and
fertile layer of soil by the agents like rainwater and wind is called soil
erosion. Soil erosion is a acute problem in India. Chambal river basin is so
badly eroded that this entire area is called as ‘Bad Land or Ravines’. There
are three types of erosion, i.e. a) Sheet Erosion, b) Rill Erosion and c) Gully
Erosion [Most Dangerous]. Followings are the reasons for soil erosion.
Reason for Soil Erosion:
a) Deforestation – Cutting down of trees and forests
b) Torrential [heavy] rainfall
c) Overgrazing by cattle
d) Unscientific agriculture [Ploughing land parallel to
the slope]
e) Excessive use of chemical fertilizers and irrigation
Measurement to Check Soil Erosion:
a) Afforestation – Planting trees on degraded land
b) Plugging of gullies
c) Check on overgrazing by cattle
d) Scientific agriculture [Ploughing land at right angle
of slope – Contour Ploughing]
e) Crop rotation
f) Terrace farming
g) Preparation of shelter belt
Short Note on Alluvial Soil
§ It is the most fertile and extensive soil in India.
§ It is found in the river valleys of Ganga, Yamuna,
Indus and Brahmaputra.
§ This soil has been formed by deposition of sediments
in the northern plain.
§ This soil is found from Punjab up to Assam. It is also
found along the coastal areas.
§ Coarse soil near the mountain foothill is called
duars, chos and tarai. In the plain area, lower parts are called khadar and
upper parts are called banger.
§ This soil is ideal for the agriculture of rice, wheat,
sugarcane, pulses and many other crops.
Short Note on Black Soil
§ This soil is formed by the weathering of lava rocks.
§ It looks black due to presence of magnesium in it.
§ It is found mainly in Maharastra, Gujarat and
Karnataka [Deccan Trap].
§ Black soil has high capacity to hold moisture. It
become sticky when it is wet and develop crack when it is dry.
§ It is best for the cultivation of cotton. Hence, it is
called as Black Cotton Soil. It is also known as ‘Regur Soil’.
CHAPTER 2: FOREST
AND WILDLIFE RESOURCES
Remember These Points
- Biodiversity: Variety of plants and animals found in an area
is called biodiversity.
- Flora: It refers to grasses, plants, trees etc of an
area.
- Fauna: It means birds, animals, reptiles, insects of
an area.
- IUCN: It full name is International Union for
Conservation of Nature.
- Biosphere
Reserve: It is vast area having
great biological diversity. In these areas, natural plants and animals are
protected for future generation. Example – Nandadevi Biosphere Reserve in
Uttranchal.
Biodiversity [Flora & Fauna] in India
- India is very
rich in biological diversity. There are variety of plants and animals
found in our country.
- India has
nearly 8% of the total number of species found in the world.
- About 81,000
species of fauna [animals] and 47,000 species of flora [plants] are found
in India.
- India is famous
for rhino, elephant, tiger, lion, monkey, snakes, peacock etc.
Biodiversity and Its Importance
Meaning of Biodiversity: Various
species of plants, trees, animals, birds, reptiles etc. found in an area is
called biodiversity. They are good natural resources. They are important
because:
a) Plants and trees give us oxygen.
b) Woods for furniture and construction are provided by
forest.
c) Some plants are of medicinal use e.g. tulsi, neem,
sarpgandha, aawla etc.
d) Leaves, roots, fruits, lac, rasin etc are collected
from forest.
e) Animals provides us meat, fur, skin, bone etc.
f) Combine, plants and animals maintain food chain in the
ecosystem.
Importance of Forest in Our Lives
a) Forest provides timber for furniture and construction
work.
b) It absorbs CO2 and provides us with
oxygen.
c) Branches, leaves and roots of trees protect soil from
erosion.
d) Forests are natural habitat for variety of wildlife.
e) Forest maintains ecological balance and food chain.
f) It provides fuel wood to rural people.
g) Lac, honey, herbs etc are collected from forest for
commercial use.
Classification of Species by IUCN
Many species of plants and animals are under threat due to over
exploitation by the human being. International Union for Conservation of Nature
[IUCN] has classified the species into following category:
a) Normal Species: There is no threat to these species, their population is sufficient in
the environment.
b) Rare Species: Species with small population is called rare. They are rarely seen in
the forest. Example – Himalayan brown bear, wild Asiatic buffalo, desert fox
etc.
c) Vulnerable Species: Population of these species decreases to such an extent that they may
become endangered. Example – blue sheep, Asiatic elephant etc.
d) Endangered Species: Population of these species become so small that they come under
danger of extinction. If negative factors continue, they may become extinction.
Example – Indian rhino, black buck, crocodile, Indian wild ass etc.
e) Extinct Species: These species are not found anywhere in the world. They have gone from
our earth for forever. Example – Asiatic Cheetah, pink head duck etc.
Reasons for Depletion of Biodiversity [Flora and Fauna]
Human activities are mainly responsible for depletion of biodiversity.
Followings are the reasons or causes behind loss of flora and fauna.
a) Deforestation, illegal cutting of trees, and forest
fire
b) Hunting and poaching of wild animals for skin, tusk,
bone etc.
c) Construction of dam, road, railways in the forest
d) Pollution and global warming leading to climatic
change
e) Increasing human population pressure on the forest
resources
Methods or Measures to Conserve Biodiversity
a) Deforestation should be totally stopped. Instead,
trees should be planted on degraded land and on land where was forest earlier.
b) People should start movement against tree cutting such
as ‘Chipko Movement’.
c) ‘Vanmahotsava’ and similar kind of events should be
celebrated to conserve forest.
d) Mass media, e.g. TV, radio, newspapers etc, should
used for creating awareness.
e) Govt. should pass and implement [Indian Wildlife
[Protection] Act – 1972] strict laws against illegal cutting of trees, hunting
and poaching.
f) Various project like Project Tiger; Project Rhine etc
should be started.
g) More National Parks, Wildlife Sanctuaries, Biosphere
Reserve should be identified.
h) There should be frequent survey and census to count
population of different species found in the forest.
Role of Community [local people] in Conserving Forest
and Wildlife
Community or local people are very helpful in conserving biodiversity
i.e. plants and animals. Many communities live in the forest. Forest is home of
many traditional people.
a) In Rajasthan, local people came forward to stop mining
activities to protect Sariska Tiger Reserve.
b) People of Alwar District of Rajasthan have declared
1200 hectares of land as ‘Bhairodev Dakav Sonchuri’ in which they don’t allow
hunting.
c) In Jharkhand, Munda tribe worship Mahua and Kadamb
trees and they protect them from cutting.
d) Famous Chipko Movement in Himalaya was started by
local community only. Beej Bachao Andolan and Navdanya movements have also been
started in Himalaya.
e) Joint Forest Management [JFM] stated in India is good
method of involving local community in forest conservation.
Types of Forests in India
a) Reserved Forests: These forests are earmarked only for production of timber. Grazing of
animals and cultivation of crops are not allowed in these forests. About 54%
forests are grouped under reserved forests.
b) Protected Forests: These forests are protected from further depletion. Right of grazing
and cultivation is allowed with certain restriction. About 29% forests come
under protected forests.
c) Unclassed Forests: There is no restriction in these forests. These forests belong to
government and private individuals. About 16% forests are unclassed forests.
Distribution of
Forest in India
§ About 33% land must be under forest for ecological
balance. But, only 23% land is under forest in India. Distribution of forest in
India is not uniform.
§ Andman and Nicobar has about 87% [Highest] land under
forest while in Haryana only 4% land is under forest which lowest in India.
§ Most of the north-eastern states like Manipur,
Mizoram, Nagaland, Arunachal Pradesh etc. have more 60% land under forest.
§ But in Punjab, Haryana, Gujarat, Rajasthan, Delhi and
J & K have less than 10% land under forest.
§ Southern states have moderately covered with forest.
About 20-30% land is under forest in these states.
Short Note on Project Tiger
Tiger is one of the most important species among fauna. It was estimated
that population of tigers has decreased rapidly in the last one hundred years.
Major reasons identified behind depletion of tiger were hunting and poaching,
deforestation, depletion of prey etc. Project Tiger was started in 1973 to
protect them from extinction. There are 27 tiger reserves in India. Project
Tiger has successfully improved the condition. Population of tigers increased
from 1800 to about 3600 in the last 30 years.
What is Sacred Groves?
In India, it is believed that everything – livings and non-livings, have
been created by god. Old tribal and traditional societies have protected
certain species from time immemorial. Munda tribes of Jharkhand protect Mahua
and Kadamb trees and worship them. People of Bihar, UP worship Peepal, Banyan,
Mango, Tamarind etc. Not only that, rivers, mountains, forests etc are
considered as god and goddesses and they are worshipped and protected in India.
CHAPTER 3: WATER
RESOURCES
Important Terms
- Dam: It is a concrete wall constructed across the
river to stop the river water. The storage of water behind the dam is
called reservoir.
- Perennial River: A river having water throughout the year is
called Perennial River. Their water source is melting glaciers, e.g.
Ganga, Brahmaputra etc.
- Reservoir: Large collection of river water just behind the
dam is called reservoir.
Water Resources in India
- Annual rainfall
in India is about 117 cm. Cherapunji receives highest rainfall in the
world.
- India has many
perennial rivers e.g. Ganga, Yamuna, Indus, Brahamputra etc. Seasonal
rivers of southern India e.g. Godawari, Krishna, Kauveri, Narmada etc are
also good source of water.
- India has long
seacoast. It is more than 6000 km. Arabian Sea, Bay of Bengal and Indian
Ocean surround southern India from three sides.
- India is also
rich in groundwater resources. There are many natural and man-made lakes,
ponds, hydraulic structures etc found in our country.
Water Scarcity and Its Causes
Water Scarcity: When water is not
available in sufficient quantity and quality for all the people in an area, it
is called water shortage or water scarcity. Water scarcity leads to drought and
famine and claims thousand of lives every year in India. Followings are the
causes of water scarcity.
a) Amount of rainfall less than the normal
b) Over exploitation of ground water by tube wells in the
cities
c) Excess use of water for irrigation to grow more crops.
d) Water pollution by dumping of waste from city and
industries
e) Flood [Water is polluted and become unfit for use]
Multipurpose Projects and Its Advantages and
Disadvantages
Meaning: A river valley project having
many dams, barrages, canals etc is called as multipurpose project. It is called
multipurpose because it serve many purposes and solve many of our problems.
Example: Bhakharan Nangal Project, Damodar Valley Project etc.
Advantage of Multipurpose Projects
a) Multipurpose projects provide water for irrigation of
crops.
b) They control the flood in the river. Damodar River was
called ‘Sorrow of Bengal’. Now, it is a blessing for that region.
c) Multipurpose projects also provide facility for
afforestation and conservation of soil from erosion.
d) Hydroelectricity, the cheapest source of emery, is
produced from multipurpose projects. About 22% electricity comes from this
source in India.
e) Canals and reservoir can also be used for water
transportation and fisheries.
Disadvantage of Multipurpose Projects
a) Fertile agricultural land submerged under the river
water.
b) Large no. of people are displaced. They have to leave
their own houses and properties.
c) Forest land are either cleared or submerged under
water. It is great loss for environment.
d) Siltation in the dam reduces the life span of the
project.
e) Big multipurpose projects can result into minor
earthquakes.
Rainwater Harvesting and Its Objectives and Methods
Meaning: Capturing and storing the
rainwater for recharging the ground water is called rainwater harvesting. Rainwater
can also be used for domestic and agricultural purpose. It is a good method of
water conservation in water scarcity areas such as Rajasthan. Rainwater is
collected on the roof of house and it is stored in dug well or underground
tank. This water is used for washing, animal drinking, irrigation etc.
Objectives of Rainwater Harvesting
a) To reduce surface run-off which cause flooding on the
roads.
b) To meet the increasing demand of water.
c) To recharge the groundwater.
d) To reduce groundwater pollution and improve the
quality of water.
e) To supply water during dry season.
Methods of Rainwater Harvesting
a) Collecting rainwater on roof top and diverting it into
a dug well to recharge groundwater.
b) Collecting rainwater on roof and bringing it
underground tank in the house for domestic use.
c) Making small check dams to stop surface run-off and
allow the soil to absorb more moisture.
d) Using bamboo as pipe to bring spring water from far
away place for irrigation like in Meghalaya.
Different Methods of Rainwater Harvesting in India
- In Rajasthan,
rainwater is collected on the roof tank to store drinking water.
- Farmer of
Rajasthan collects rainwater in their agricultural fields to increase the
soil moisture. It is called ‘Khadins’ and ‘Johad’ in Rajasthan.
- People of
Rajasthan, also built underground tank [Called as ‘Tankas’] to store
drinking water for at least a year.
- In West Bangal,
people developed inundation channels to irrigate their fields.
- In the hilly
and mountainous areas, people build diversion channel called as ‘Guls’ and
‘Kuls’ for development of agriculture.
- Collection of
rainwater is also done in Shillong for household requirement.
- In Meghalaya,
people use bamboo [Bamboo Drip] as pipes to bring water spring water
located hundreds of meters away from the houses.
- Tamil Nadu is
the first state to make rooftop rainwater harvesting compulsory in every house
across the state.
Watershed Development:
An area drained by an tributary is called watershed. All round
development of this area is called watershed development. Sukhmajri Village in
Haryana is the best example of watershed development. Attempt made under
watershed development are:
- Conservation of
soil and moisture,
- Afforestation
and forest upgradation,
- Water
harvesting,
- Development of
horticulture
- Pasture
development
- Supply of
drinking water
CHAPTER 4: AGRICULTURE
Important Terms
- Agriculture: Cultivation of crops and domestication of
animals is called agriculture.
- Cash Crops: The crops which are cultivated for trade and
commerce and selling them in the market to earn money, like tobacco,
spices, fruits, sugarcane etc.
- Animal
Husbandry: Domesticating animals for
production of milk and meat is called animal husbandry.
- Green
Revolution: Sudden rise in the
production of crops by using HYV seeds, irrigation water, chemical
fertilizers etc. is called green revolution. It took place during 1960s in
our country.
- Horticulture: Cultivation of fruits and vegetables is called
as horticulture.
- Sericulture: Rearing of silk worm and producing silk is
called sericulture.
- Jhumming: Shifting agricultural in the north east is
called as jhumming. It is also called slash and burn agriculture because
tree are cut and burnt to clear the land for agriculture.
- PDS: It means Public Distribution System. It is a
program which provides foodgrains and other essential items [Rice, Wheat,
Sugar, Kerosene Oil etc.] to rural people at subsidized rate [low price].
- Minimum Support
Price [MSP]: It is a lowest
price announced by the Govt. at which foodgrains are procured by FCI [Food
Corporation of India].
- Genetic
Engineering: It means
developing new and hybrid seed by using modifying the gene of the crops.
- Shifting
Agriculture: It is also
called as slash and burn agriculture. In this agriculture forest land is
cleared and they are burnt. Agriculture is done using very old tools on
very small scale. After one or two year new land is selected and same
process is followed. This method of agriculture is very old; and gives
very low production; and also it degrade forest. In the north-east this
agriculture is called as jhumming or jhum cultivation.
- Important Crops
in India:
- Cereal Crops:
Rice, Wheat, Bajra
- Millets:
Jowar, Bajra and Ragi
- Pulses: Tur
[Arhar], Urad, Moong, Masur, Peas, Gram
- Oilseeds:
Mustard, Coconut, Groundnut, Coconut, Sunflower, Soyabean
- Beverage: Tea,
Coffee
- Fiber Crops: Cotton,
Jute, Hemp and Natural Silk
- Cash Crops:
Sugarcane, Rubber, Tobacco, Spices
- Operation Flood: It means sharp rise in the production of milk.
It is also called as White Revolution.
Important Features and Characteristics of Indian
Agriculture
a) Indian agriculture is subsistence in nature. It means
produce is consumed by the farmer itself.
b) Agriculture is dependent on monsoon rain. Only 1/3rd
net sown is under irrigation.
c) Consumption of chemical fertilizer, HYV seeds,
pesticide etc is very low.
d) Size of agriculture fields is very small.
e) Machines and modern farm implements are used only in
small area.
f) Food crops [rice, wheat] are more important than
commercial crops.
g) There are poor banking and insurance facility
available to the farmers.

Plantation Agriculture
§ It is a type of commercial agriculture which need huge
investment of money.
§ It is single crop farming practiced on large land.
§ Plantation agriculture was started by British in
India.
§ Generally it is done in hilly and sloppy area where
rainfall is high and water can drain easily.
§ Heavy dose of fertilizers, pesticides etc are required.
§ Efficient and fast transport and communication help
this farming to connect with market.
§ Important crops are tea, coffee, banana, spices,
rubber etc.
Technological and Institutional Reforms
Agricultural in India is thousands of year old. It is subsistence in
nature because farmers consume most of the produce by themselves. But because
of use of modern technology and institutional reform Indian agriculture is
becoming commercial. Green Revolution [Crops] and White Revolution [Milk –
Operation Flood] is the result of these two reforms.
Technological Reforms:
a) Wooden plough was replaced with tractors and tillers.
b) Drip irrigation and sprinklers are now used for
irrigation which irrigates more area in less water.
c) Use of chemical and bio fertilizers have increase
manifold. HYV Seeds, pesticide, insecticides are also used more.
d) Biotechnology has developed much genetically improved
variety of seed which are resistant to drought and pest. They give more
production also.
e) Farmers are now using TV, Radio, Newspapers and Cell
Phone to know about weather condition and according they plan agricultural
activities.
Institutional Reforms:
a) Zamindari system was abolished by the Government of
India.
b) Small fields were consolidated to make large fields.
c) Agriculture was the main focus in the first Five Years
Plan.
d) Kissan Credit Card [KCC], Personal Accident Insurance
Scheme [PAIS] was started by Govt. to help the Indian farmers.
e) Govt. also announces Minimum Support Price and has
abolished the role of middleman in the market.

Contribution of Agriculture to National Economy
a) Agriculture is the backbone of Indian Economy. About
63% people are directly dependent on agriculture for their livelihood.
b) About 40% of national income comes for agricultural
sector alone.
c) Agriculture also provides raw materials to many
industries e.g. sugar, textile, food and beverage industries.
d) It also has ensured food security. FCI procure crops
at minimum support price to stock. It also distribute among people under PDS
[Public Distribution System].
e) India export wheat, sugar, fruits, tea to foreign
countries and earn foreign exchange.
f) Agriculture also brings happy, prosperity and
development in rural economy.
Food Security and Methods of Ensuring Food Security
Food Security: Food is the basic requirement of all the people in the
country. But many people are not able to get sufficient meals at least two
times in a day. During natural disaster like earthquake, flood, drought there
is shortage of food all over the country. Food security is a method to ensure
at least minimum quantity of food for all the people round the year. Food
Corporation of India [FCI] procure foodgrains at Minimum Support Price and
maintain food security by two ways: a) Buffer Stock and b) Public Distribution
System [PDS].
Methods of Ensuring Food Security in India
a) More area should be brought under cultivation of
foodgrains like rice, wheat, pulses and oil seeds.
b) HYV Seeds should be used which gives more production
per hectare of land.
c) Biotechnology can be used to modify genetics of seed
so that it can resist drought, flood and diseases and give more production.
d) More multipurpose projects should be undertaken to
improve agriculture.
e) Modern machines and tools should be used in
agriculture like tractor, harvester, sprinklers etc.
f) Farmer should be given banking and insurance
facilities.
g) All forms of soil erosion should be checked and soil
should be conserved.
Globalization and Its impact on Indian Agriculture
Meaning: Integrating the national economy with the economy of other
countries of the world is called globalization. It has made cross-border flow
of money, technology and people very easy.
Positive Impact of Globalization
a) Indian farmers will have access to internal market.
They can sell their produce at international prices.
b) Capital investment from foreign countries will develop
the Indian agriculture.
c) Globalization will bring competitiveness among farmers
which will lead to commercialization of Indian agriculture.
d) Indian farmers can also use modern technology and
machineries which are now used only in foreign countries.
e) Globalization will also help in biotechnology and
genetic engineering in India.
Negative Impact of Globalization
a) Multinational Companies [MNCs] of developed countries
will exploit our farmers as Indian farmers are poor and illiterate.
b) Small farmers of India cannot compete with farmers of
developed nations.
c) Indian farmers may not get the international buyers as
quality of our crops is not as per the international standard.
d) Due to globalization, Indian farmers will try to grow
more cash crops and there will be shortage of food in our country.

Mineral and Its Classification
Meaning: Minerals are natural substance which has certain physical and
chemical properties like colour, hardness, texture, crystals etc. Minerals are
very important as most of the things we use in our lives are made of one or
other minerals. Minerals are mined from earth surface. There are about 2000
types of minerals identified so far but few of them are very important like
iron, cooper, mineral oil, bauxite etc. Minerals can be classified as under:
1] Metallic Minerals: Metals are obtained from them.
a) Ferrous [Contain
Iron]: Iron Ore, Manganese, Nickel, Cobalt
b) Non-Ferrous [No
Iron]: Copper, Lead, Tin, Bauxite
c) Precious [Costly]:
Gold, Silver, Platinum
2] Non-Metallic Minerals: Metals are not obtained from them.
Mica, Salt, Potash,
Limestone, Marble, Sandstone
3] Energy Minerals: These minerals provide us energy.
Coal, Petroleum and
Natural Gas
Mode of Occurrence [Where are minerals found?]
Minerals are found in the earth surface [crust]. They are extracted by
mining activities. Minerals take millions of year to form; therefore they are
called as non-renewable resource.
h) In the veins and lodes of igneous rock
and metamorphic rock important metallic minerals are found like cooper, zinc,
tin, lead etc.
i) Energy minerals such as coal, petroleum and natural
gas are found in the beds and layers of sedimentary rocks.
j) Alluvial deposits [also called as placer deposits]
contain very precious minerals like gold, silver, tin, platinum etc.
k) Ocean water also contains many minerals like salt,
magnesium, bromide etc.
l) Weathered materials of the rocks contain bauxite [aluminum].

Karnataka. Iron ore mined from Kudremukh [Largest deposit in the world]. Ore is
exported to USA and Europe.
d) Maharastra-Goa Belt: Goa and Ratnagiri are important
mining place of iron ore.
Coal, Its Types and Distribution
Coal is a type of fossil fuel and the most important source of energy in
our country. Coal is formed by burial of plants and animals in the rocks for
million of years. Coal is used for generating thermal electricity and for
smelting iron ore. Coal in India is found mainly in Gondwana Rocks
series of river Damodar, Mahanadi, Godawari etc. There are four types of coal
as per carbon content.

Cotton Textile Industry and Its Problems
- It is an
agro-based and the oldest industry in India. First cotton mill was
established in 1854 in Mumbai. At present, it the largest industry in our
country. There are about 1600 cotton textile mills in our country.
- Cotton textile
mills are mainly concentrated in Maharastra and Gujarat due to favourable
conditions. Important centres are Mumbai, Pune, Ahmedabad, Suar, Rajkot
etc. Other centres are Agra, Kanpur, Hugli, Chennai, Madurai etc.
- Cotton textile
is produced by three methods in India: a) Handloom, b) Power-looms and c)
Mills
- Cotton textile
industry involves ginning, spinning, weaving, dyeing, designing, tailoring
and packaging to produce readymade garments.
- India export
yarn and readymade garments to USA, Japan, UK, France, Nepal, Sri Lanka
etc.
- Cotton textile
industries are facing many problems such as: a) scarcity of good quality
cotton, b) main cotton growing area went to Pakistan, c) old machinery, d)
erratic power supply, e) low productivity of labour, f) tough competition
from synthetic fibers.
Iron & Steel Industry and Its Problems
- This industry
is called as basic industry because it provide raw material to many other
industries such as machine an tools, transport equipment, construction
material etc. It is also called as heavy industry because raw materials
[iron ore, coal, limestone] are bulky in nature.
- Iron ore mixed
with limestone is smelted in the blast furnace using coking coal to
produce pig iron. The ratio of iron ore, limestone and coking coal used in
4:2:1.
- Pig iron is
mixed with manganese, chromium and nickel which make it more stronger
steel.
- Most of the
steel plants are located in Chotanagpur region due to its favourable
conditions. At present there are 10 integrated iron and steel plants and
many small and mini plants. Important integrated steel plants are
Jamshedpur, Durgapur, Bokaro, Bhilai, Burnpur etc.
- India produces
about 33 million tons of steel every year even though per capita
consumption of steel is very low i.e. 32 kg. It is low because India has
low economic and industrial development.
- Today steel
industries in India are facing many problems: a) High cost of production,
b) Limited availability of coking coal, c) Low productivity of labour, d)
Irregular supply of energy, e) Raw materials are found in a certain pocket
of India only, f) Poor infrastructure like transport and communication
etc.
Jute Industries and Its Problems
- India is
largest producer of raw jute and jute goods. There are about 70 jute mills
in our country.
- First jute mill
was setup in Rishra [Kolkata] in 1859. Most of the jute mills are located
along Hugli River in West Bengal due to favourable condition.
- Jute is used in
making rope, bags, carpets etc. Bihar, UP, Assam and Tripura also have
jute miils.
- Jute industries
are facing problems like: a) main jute producing area went to Bangladesh,
b) high production cost, c) declining demand of jute in international
market, d) tough competition from synthetic fiber industry.
Why cotton industries are mainly concentrated in
Maharastra and Gujarat?
Cotton textile industries are located mainly in Maharastra [around
Mumbai] and Gujarat [around Ahmedabad] because of the following reasons.
a) Raw Materials: These areas have easy access to raw
material i.e. cotton. Maharastra and Gujarat are the largest producer of cotton
in India.
b) Favourable Climate: Humid climate is required for
cotton textile. Maharastra and Gujarat have humid climate as they are located
near to Arabian Sea. This climate is also good for cultivation of cotton.
c) Availability of Capital: Mumbai is the financial
capital of our country. It provides finance and capital to cotton textile.
d) Labour: Maharastra and Gujarat are heavily populated
area. Cheap labours are available in this region.
e) Transport and Communication: Mumbai, Ahmedabad, Surat,
Pune etc are well connected by road and rail with other part of the country.
Mumbai port is used to export readymade garments to European Countries.
Why iron and steel industries are located mainly in Chotanagpur
Region?
Most of important integrated steel plants are locate in Chotanagpur
region i.e in Jharkhand, Chattisgarh, Orrisa etc. It is because of the
following reasons:
a) Raw Material: Chotanagpur area is rich in iron ore. Iron ore is extracted from Singbhum,
Mayurbhanj, Kendujhar etc.
b) Energy: Coal is
used for smelting iron ore in the blast furnace. Coal is available from
Raniganj, Dhanbad, Jharia and Bokaro.
c) Cheap labour: Bengal, Bihar and Orissa have high density of population. Therefore,
cheap labour is available in this region.
d) Transport: This region
is well connected by road and railway with other parts of the country.
Nantional Highway 2, Delhi – Howrah and
Howrah – Mumbai rail route passes through this region.
e) Capital: Kolkata is
a megacity which provide capital, banking and insurance facility.
Jute industries are located mainly along Hooghly
River. Why?
There are 69 jute mills located in a 2 km broad belt along Hooghly
River. This area provides many favourable conditions required for this industry.
a) Raw jute is available for West Bengal. West Bengal is
the largest producer of jute.
b) Coal for energy is brought from nearby Raniganj
Coalfields.
c) Hooghly River provides water for washing and cleaning
jute.
d) Warm and humid climate is very favourable for
cultivation of jute and jute industry.
e) Kolkata is a metro city which provides capital and
market.
f) Hooghly River also provides cheap water transport.
Sugar industry is shifting from northern to southern
India. Why?
Earlier UP and Bihar were the main producer of sugarcane. Therefore,
most of the sugar mills were located in these two states only. But now, sugar
mills are shifting towards Maharastra and Karnataka because of following
reasons.
a) Per hectare production of sugarcane is higher in
southern India. Black soil is quite suitable for cultivation of sugarcane.
b) Sucrose content in the sugarcane is higher in
Maharastra and Karnataka. It means more sugar can be produced for less
sugarcane.
c) Mills and machines are new in southern states. New and
modern machines increase the productivity.
d) Crushing season for sugarcane is longer in southern
states.
e) Cooperative sugar mills are running successfully in
southern states.
Industrial Pollution and Environmental Degradation
a) Air pollution is caused by the emission of CO2,
Carbon Monoxide, Sulphur Dioxide etc. Chimneys of the industries produce heat
leading to Global Warming and Green House Effect. Use of CFC in various
industrial products depletes ozone layer which filters ultraviolet rays of the
sun.
b) Dumping of organic and inorganic industrial waste into
water bodies pollute the water. Industries which produce paper, pulp, chemical,
leather, acids, dyes, fertilizers etc generate lots of toxic waste which kills
the aquatic life.
c) High intensity sound generated by running machines,
siren, drilling, fans etc leads to noise pollution. It causes irritation,
hearing impairment, heart attack etc. among the nearby people.
d) Mining activity to get raw material for industries
also degrade the environment. Land degradation, deforestation, soil erosion,
water logging etc. of result of mining activities.
Measurement [Methods] for Controlling Environmental
Pollution and Degradation
a) Industries should be located with careful planning and
better design.
b) Quantity of smoke can be reduced by using oil instead
of coal.
c) Non-conventional sources of energy should be used
instead of fossil fuels.
d) Modern equipment should be used which controls,
filters and separate harmful materials from the waste.
e) Waste water should be properly treated before discharging
into rivers.
f) Land filling method should be adopted for dumping of
waste.
g) Polluting industries should be located away from town
and cities.

System [Conversion of all gauges into broad gauge], f) Replacement of Steam
Engine with Electric Engine, g) Special Trains like Rajdhani, Shatabdi, Jan
Shatabdi, Summer Special etc.
Merits or Advantage of Railways
- Good for
transportation of bulky and heavy materials
- It is cheaper
for transporting goods for longer distances.
- Best for
transportation of raw materials e.g. iron ore, manganese, coal etc.
- It is fast mode
transportation.
- Large number of
passengers can be transported.
- Railway
provides various facilities such as night berth, catering, computerized
reservation etc.
Pipelines in India and Its Advantages
- Pipelines are
used to transport gas and liquid materials such as mineral or refined oil,
natural gas, water or even milk. Solid items can also be transported after
making it ‘slurry’.
- Pipelines are
found from oil producing centers to oil refinery plants and from oil
refinery plants to the market [city].
- Minerals oil
from upper Assam is transported to Barauni and Allahabad oil refinery
through pipeline.
- Pipeline from
Salaya to Jalandhar via Mathura and Delhi is also very important pipeline.
- The longest
pipeline in India is H-B-J pipeline which connect Hazia, Bijapur and
Jagdishpur. It is about 1700 km. long.
Advantage of Pipeline Transportation
- Pipeline is
best for transportation of gas and liquid materials e.g. oil, natural gas,
water and milk.
- Construction of
pipeline is cheaper than road and railways.
- Pipeline can be
constructed in forest, swampy area, hills and desert. It can also be laid
down under river and ocean water.
- Pipeline can
ensure regular, quick and on-demand supply of liquid and gaseous
materials.
- Pipelines can
be operated at low energy cost and it does not pollute environment.
Water Transportation in India
- Water
transportation is cheapest among all mode of transportation because there
is no need to construct any route.
- They are
cheaper for transporting bulky and heavy raw materials.
- India has many
perennial and seasonal rivers which offer transport facility. India has
about 14,500 km long inland navigation waterways.
- India also has
long sea coast on which there are many ports like Mumbai, Goa, Kochhi,
Chennai, Vishakhapatnam, Haldia etc.
- India has three
National Waterways:
- National
Waterways – 1 Ganga 1620
km. Allahabad – Haldia
- National
Waterways – 2 Brahmaputra 891 km. Sadiya – Dhubri
- National
Waterways – 3 West Coast Canal 205 km. Kollam
- Kottapuram
- There are some
problems in using waterways like: a) Peninsular rivers are seasonal, b)
Many rivers make waterfalls in their course, c) Water transportation is
slowest among all transport modes, d) Construction of dams and barrage
also blocks waterways, e) Many rivers flow in uninhabited area, f) Indian
coast are shallow and we have less natural ports.

and most comfortable mode of transport. It can cover long distance within
hours.
- River, hills,
forest, oceans etc. do not come in the way of air transport.
- Air transport
play very important role in rescue operation during natural disasters like
flood and earthquake.
- It also
connects isolated and far away places with main stream of the country. It
is best for north-eastern states and Jammu and Kashmir.
- In India,
domestic service is provided by ‘Indian Airlines’. It covers major cities
of India and neighboring countries. International air transport service is
provided by ‘Air India’.
- Pawanhans
provides helicopter facility. Private companies like Sahara, Kingfisher
are also operating air transportation in India.
- Problems: a)
Air transport is very costly and not suited for common people, b)
Construction of airport needs huge capital and technology, c) Airports
cannot be constructed everywhere.

India Trade and Its Types
§ Meaning of Trade: Exchange of goods and services among people is called as trade. In
other words, buying and selling goods and services is called trade. The place
where trade takes place is called as market or trading center. Trade takes
place because all parts of world do not have same resources and they do not
produce same commodity. Higher amount of trade indicate higher economic
development of a country.
§ Balance of Payment: The ratio between value of export and import is called balance of
payment. If export is higher than import, it is called ‘favourable balance of
payment’. If import is higher than export, it is called negative balance of
payment.
§ Export from India: Petroleum products, engineering goods, gems and jewellery, computer
software, chemical products and agricultural products are exported by India to
other countries.
§ Import to India: Petroleum, pearls and precious stones, coal, inorganic chemicals,
fertilizers, electronic consumer durables are imported by India from other
countries.

CHAPTER 1: RESOURCES
AND DEVELOPMENT
Remember These Points
- Anything
available in the environment and can be used to satisfy the needs of human
being is called as resource, e.g. water, land, air, minerals, wildlife
etc.
- Leaching is a
process which takes place in high temperature and rainfall area. In this
process minerals of the soil are dissolved into the rainwater and they
move down in the soil. Laterite soil is formed by this process.
- Black soil is
also called as ‘regur soil’.
- Manganese
nodules are extracted from Indian Ocean.
- Full form of
UNCED is United Nations Conference on Environment and Development.
- Rajasthan has
abundant solar and wind energy potential.
- Earth Summit
was held in Rio de Jeniro [Brazil] in 1992.
- The book
written by Schumacher is ‘Small is Beautiful’.
- Black soil is
formed by weathering of lava rocks.
- Red soil is
formed by weathering of igneous rocks. It looks red due to iron-oxide.
- Land degraded
by gully erosion in Chambal River basin is called ‘Ravines’ or ‘Bad Land’.
Types or Classification of Resources
On the basis of origin:
- Biotic: Those
resources which has life are called biotic resources e.g. plants, trees,
animals etc.
- Abiotic: Those
resources which do not have life are called as abiotic resources e.g.
land, water, minerals etc.
On the basis of exhaustibility:
a) Renewable [Forest, Wildlife, Water]
b) Non-Renewable [Metals, Fossils Fuels]
On the basis of ownership:
a) Individual [land, plot, well, pond]
b) Community [Grazing land, burial ground, park]
c) National [Minerals, Forest, Rivers]
d) International [EEZ – Ocean up to 200 km]
On the basis of development:
- Potential
Resources: Resources which are found in an area but not have been
utilized. For example, Rajasthan and Gujurat has enough potential to
produce solar energy due to cloudless sky and more temperature.
- Developed
Resources: When resources found in a region are surveyed by engineer and
their quality and quantity are determine for utilization, it is called developed
resource. Technology and capital help in development of resources.
- Stock
Resources: Material found in our environment can satisfy many of our need
but they are not used because of lack of appropriate technology. For
example, water has hydrogen, a good source of energy, but due appropriate
technology water is not being used as fuel.
- Reserve
Resources: Reserve is those parts of stock which can be utilized using
existing technology. But these resources are not being used and they have
been left for future generation. They are called reserve.
Sustainable Development: Development without damaging the environment is
called as sustainable development. This development meets the demands of
present generation as well as future generations.
Earth Summit and Agenda 21: Earth Summit is an international conference on
environment. It was held in Rio de Jeniro [Brazil] in 1992. In the conference
leaders of the words discussed about sustainable development and they adopted
21 points policy which is called ‘Agenda 21’.
Resource Planning and Its Steps
Resource planning is method to use the resources in optimum way so that
maximum benefit should reach to maximum people. Resource planning also means
avoiding wastage, misuse and overuse of resources. There are three steps for
resource planning.
a) Identification and inventory of resources by surveying
and mapping
b) Evolving a planning structure to use the resources
with appropriate technology
c) Matching resource development plan with national
development plan
Need and Methods of Conservation of Resources
Father of the nation – Mahatma Gandhi – said that “There is enough for
everybody’s need and not for anybody’s greed”. We should conserve resources for
following reasons.
a) Resources are not found everywhere. They are unevenly distributed.
b) Resources are limited. Many of the resources are
non-renewable.
c) Resources should be conserved for reducing all kinds
of pollution.
d) Resources are also conserved for ‘sustainable
development’.
e) Conservation is needed to protect natural heritage.
Methods or measurements for resource conservation are as under:
a) Wastage, misuse and overuse of resources should be
avoided.
b) Renewable resources should be used more e.g. solar
energy, wind energy etc.
c) Older technology should be replaced with newer, modern
and efficient technology.
d) Awareness should be created among the people.
e) Govt. should pass strict laws for establishment and
location of industries.
f) Used items should be recycled using new technology.
Land Use and Its Category
Land is used for various purposes in a country. India has vast land
resource. Total area of our country is about 3.28 million sq. km. India ranks 7th
in the world in term of size. But most of parts are covered by either mountain
or plateau. India has only 43% plain where agriculture is possible. Mountains
are good sources of biotic resources where varieties of minerals are found in
the plateau. There are 5 categories under land use.
- Forest
- Land not
available for cultivation
- Other
uncultivated land
- Fallow land
- Net sown area
§ Land not available for cultivation includes barren land, waste land and land which is
used for building, roads, parks, factories etc.
§ Fallow land is that land which is left uncultivated by the farmer. Farmer leaves
some land to give rest to the land. Lands are also left fallow due low
rainfall, lack of capital or seeds etc. Fallow land for one or less than one
year is called Current Fallow. If land is left fallow for more than one but
less than five years it is called as Other Fallow land.
§ Net sown area is the actual land on which agriculture is done. Some parts of net sown
area is used more than one time in a single agricultural season. When this land
is added with net sown area, it is called gross sown area or gross cropped
area.
Land Degradation and Its Causes
Lowering the quality of land up to such an extent that the land become
unfit for any use, it is called as land degradation. About 130 million hectare
of lands are degraded in India. Following are the causes of land degradation.
a) Deforestation – cutting of trees and forest
b) Erosion by rain water and wind
c) Water logging in low lying area
d) Increasing salinity [salt] due to over irrigation
e) Dumping of urban and industrial waste on valuable land
f) Mining and quarrying activities for extracting
minerals
Soil, Its Formation & Factors Affecting Soil
Formation
Meaning of Soil: It is an important
an renewable resource. It is upper part of the crust which is loose and
fragmented. It has air, water and minerals contents and it support growth of
plants. Bacteria and other small organisms are also found in the soil which
makes it more fertile.
Formation of Soil: Soil is formed by
weathering and erosion of rocks. Temperature and rainfall breaks down the rock
into smaller parts. After mixing of water and minerals in these sediments, it acquires
the form of soil. Following factors affect soil formation.
Factors Affecting Soil Formation
a) Parent Rocks: It determined the colour, texture and
mineral contents in soil
b) Climate [Rainfall and Temperature]: It determines rate
of weathering and erosion of rocks.
c) Topography [Slope]: On higher land thin layer of soil
is found, while in the lower valley thick deposition of alluvium is found.
d) Vegetation [Plants and Trees]: They add organic matter
[Humus] to the soil.
e) Time: Older soils are generally more fertile than
newer soil.
Soil Erosion and Methods of Soil Conservation
Soil Erosion: Removal of top and
fertile layer of soil by the agents like rainwater and wind is called soil
erosion. Soil erosion is a acute problem in India. Chambal river basin is so
badly eroded that this entire area is called as ‘Bad Land or Ravines’. There
are three types of erosion, i.e. a) Sheet Erosion, b) Rill Erosion and c) Gully
Erosion [Most Dangerous]. Followings are the reasons for soil erosion.
Reason for Soil Erosion:
a) Deforestation – Cutting down of trees and forests
b) Torrential [heavy] rainfall
c) Overgrazing by cattle
d) Unscientific agriculture [Ploughing land parallel to
the slope]
e) Excessive use of chemical fertilizers and irrigation
Measurement to Check Soil Erosion:
a) Afforestation – Planting trees on degraded land
b) Plugging of gullies
c) Check on overgrazing by cattle
d) Scientific agriculture [Ploughing land at right angle
of slope – Contour Ploughing]
e) Crop rotation
f) Terrace farming
g) Preparation of shelter belt
Short Note on Alluvial Soil
§ It is the most fertile and extensive soil in India.
§ It is found in the river valleys of Ganga, Yamuna,
Indus and Brahmaputra.
§ This soil has been formed by deposition of sediments
in the northern plain.
§ This soil is found from Punjab up to Assam. It is also
found along the coastal areas.
§ Coarse soil near the mountain foothill is called
duars, chos and tarai. In the plain area, lower parts are called khadar and
upper parts are called banger.
§ This soil is ideal for the agriculture of rice, wheat,
sugarcane, pulses and many other crops.
Short Note on Black Soil
§ This soil is formed by the weathering of lava rocks.
§ It looks black due to presence of magnesium in it.
§ It is found mainly in Maharastra, Gujarat and
Karnataka [Deccan Trap].
§ Black soil has high capacity to hold moisture. It
become sticky when it is wet and develop crack when it is dry.
§ It is best for the cultivation of cotton. Hence, it is
called as Black Cotton Soil. It is also known as ‘Regur Soil’.
CHAPTER 2: FOREST
AND WILDLIFE RESOURCES
Remember These Points
- Biodiversity: Variety of plants and animals found in an area
is called biodiversity.
- Flora: It refers to grasses, plants, trees etc of an
area.
- Fauna: It means birds, animals, reptiles, insects of
an area.
- IUCN: It full name is International Union for
Conservation of Nature.
- Biosphere
Reserve: It is vast area having
great biological diversity. In these areas, natural plants and animals are
protected for future generation. Example – Nandadevi Biosphere Reserve in
Uttranchal.
Biodiversity [Flora & Fauna] in India
- India is very
rich in biological diversity. There are variety of plants and animals
found in our country.
- India has
nearly 8% of the total number of species found in the world.
- About 81,000
species of fauna [animals] and 47,000 species of flora [plants] are found
in India.
- India is famous
for rhino, elephant, tiger, lion, monkey, snakes, peacock etc.
Biodiversity and Its Importance
Meaning of Biodiversity: Various
species of plants, trees, animals, birds, reptiles etc. found in an area is
called biodiversity. They are good natural resources. They are important
because:
a) Plants and trees give us oxygen.
b) Woods for furniture and construction are provided by
forest.
c) Some plants are of medicinal use e.g. tulsi, neem,
sarpgandha, aawla etc.
d) Leaves, roots, fruits, lac, rasin etc are collected
from forest.
e) Animals provides us meat, fur, skin, bone etc.
f) Combine, plants and animals maintain food chain in the
ecosystem.
Importance of Forest in Our Lives
a) Forest provides timber for furniture and construction
work.
b) It absorbs CO2 and provides us with
oxygen.
c) Branches, leaves and roots of trees protect soil from
erosion.
d) Forests are natural habitat for variety of wildlife.
e) Forest maintains ecological balance and food chain.
f) It provides fuel wood to rural people.
g) Lac, honey, herbs etc are collected from forest for
commercial use.
Classification of Species by IUCN
Many species of plants and animals are under threat due to over
exploitation by the human being. International Union for Conservation of Nature
[IUCN] has classified the species into following category:
a) Normal Species: There is no threat to these species, their population is sufficient in
the environment.
b) Rare Species: Species with small population is called rare. They are rarely seen in
the forest. Example – Himalayan brown bear, wild Asiatic buffalo, desert fox
etc.
c) Vulnerable Species: Population of these species decreases to such an extent that they may
become endangered. Example – blue sheep, Asiatic elephant etc.
d) Endangered Species: Population of these species become so small that they come under
danger of extinction. If negative factors continue, they may become extinction.
Example – Indian rhino, black buck, crocodile, Indian wild ass etc.
e) Extinct Species: These species are not found anywhere in the world. They have gone from
our earth for forever. Example – Asiatic Cheetah, pink head duck etc.
Reasons for Depletion of Biodiversity [Flora and Fauna]
Human activities are mainly responsible for depletion of biodiversity.
Followings are the reasons or causes behind loss of flora and fauna.
a) Deforestation, illegal cutting of trees, and forest
fire
b) Hunting and poaching of wild animals for skin, tusk,
bone etc.
c) Construction of dam, road, railways in the forest
d) Pollution and global warming leading to climatic
change
e) Increasing human population pressure on the forest
resources
Methods or Measures to Conserve Biodiversity
a) Deforestation should be totally stopped. Instead,
trees should be planted on degraded land and on land where was forest earlier.
b) People should start movement against tree cutting such
as ‘Chipko Movement’.
c) ‘Vanmahotsava’ and similar kind of events should be
celebrated to conserve forest.
d) Mass media, e.g. TV, radio, newspapers etc, should
used for creating awareness.
e) Govt. should pass and implement [Indian Wildlife
[Protection] Act – 1972] strict laws against illegal cutting of trees, hunting
and poaching.
f) Various project like Project Tiger; Project Rhine etc
should be started.
g) More National Parks, Wildlife Sanctuaries, Biosphere
Reserve should be identified.
h) There should be frequent survey and census to count
population of different species found in the forest.
Role of Community [local people] in Conserving Forest
and Wildlife
Community or local people are very helpful in conserving biodiversity
i.e. plants and animals. Many communities live in the forest. Forest is home of
many traditional people.
a) In Rajasthan, local people came forward to stop mining
activities to protect Sariska Tiger Reserve.
b) People of Alwar District of Rajasthan have declared
1200 hectares of land as ‘Bhairodev Dakav Sonchuri’ in which they don’t allow
hunting.
c) In Jharkhand, Munda tribe worship Mahua and Kadamb
trees and they protect them from cutting.
d) Famous Chipko Movement in Himalaya was started by
local community only. Beej Bachao Andolan and Navdanya movements have also been
started in Himalaya.
e) Joint Forest Management [JFM] stated in India is good
method of involving local community in forest conservation.
Types of Forests in India
a) Reserved Forests: These forests are earmarked only for production of timber. Grazing of
animals and cultivation of crops are not allowed in these forests. About 54%
forests are grouped under reserved forests.
b) Protected Forests: These forests are protected from further depletion. Right of grazing
and cultivation is allowed with certain restriction. About 29% forests come
under protected forests.
c) Unclassed Forests: There is no restriction in these forests. These forests belong to
government and private individuals. About 16% forests are unclassed forests.
Distribution of
Forest in India
§ About 33% land must be under forest for ecological
balance. But, only 23% land is under forest in India. Distribution of forest in
India is not uniform.
§ Andman and Nicobar has about 87% [Highest] land under
forest while in Haryana only 4% land is under forest which lowest in India.
§ Most of the north-eastern states like Manipur,
Mizoram, Nagaland, Arunachal Pradesh etc. have more 60% land under forest.
§ But in Punjab, Haryana, Gujarat, Rajasthan, Delhi and
J & K have less than 10% land under forest.
§ Southern states have moderately covered with forest.
About 20-30% land is under forest in these states.
Short Note on Project Tiger
Tiger is one of the most important species among fauna. It was estimated
that population of tigers has decreased rapidly in the last one hundred years.
Major reasons identified behind depletion of tiger were hunting and poaching,
deforestation, depletion of prey etc. Project Tiger was started in 1973 to
protect them from extinction. There are 27 tiger reserves in India. Project
Tiger has successfully improved the condition. Population of tigers increased
from 1800 to about 3600 in the last 30 years.
What is Sacred Groves?
In India, it is believed that everything – livings and non-livings, have
been created by god. Old tribal and traditional societies have protected
certain species from time immemorial. Munda tribes of Jharkhand protect Mahua
and Kadamb trees and worship them. People of Bihar, UP worship Peepal, Banyan,
Mango, Tamarind etc. Not only that, rivers, mountains, forests etc are
considered as god and goddesses and they are worshipped and protected in India.
CHAPTER 3: WATER
RESOURCES
Important Terms
- Dam: It is a concrete wall constructed across the
river to stop the river water. The storage of water behind the dam is
called reservoir.
- Perennial River: A river having water throughout the year is
called Perennial River. Their water source is melting glaciers, e.g.
Ganga, Brahmaputra etc.
- Reservoir: Large collection of river water just behind the
dam is called reservoir.
Water Resources in India
- Annual rainfall
in India is about 117 cm. Cherapunji receives highest rainfall in the
world.
- India has many
perennial rivers e.g. Ganga, Yamuna, Indus, Brahamputra etc. Seasonal
rivers of southern India e.g. Godawari, Krishna, Kauveri, Narmada etc are
also good source of water.
- India has long
seacoast. It is more than 6000 km. Arabian Sea, Bay of Bengal and Indian
Ocean surround southern India from three sides.
- India is also
rich in groundwater resources. There are many natural and man-made lakes,
ponds, hydraulic structures etc found in our country.
Water Scarcity and Its Causes
Water Scarcity: When water is not
available in sufficient quantity and quality for all the people in an area, it
is called water shortage or water scarcity. Water scarcity leads to drought and
famine and claims thousand of lives every year in India. Followings are the
causes of water scarcity.
a) Amount of rainfall less than the normal
b) Over exploitation of ground water by tube wells in the
cities
c) Excess use of water for irrigation to grow more crops.
d) Water pollution by dumping of waste from city and
industries
e) Flood [Water is polluted and become unfit for use]
Multipurpose Projects and Its Advantages and
Disadvantages
Meaning: A river valley project having
many dams, barrages, canals etc is called as multipurpose project. It is called
multipurpose because it serve many purposes and solve many of our problems.
Example: Bhakharan Nangal Project, Damodar Valley Project etc.
Advantage of Multipurpose Projects
a) Multipurpose projects provide water for irrigation of
crops.
b) They control the flood in the river. Damodar River was
called ‘Sorrow of Bengal’. Now, it is a blessing for that region.
c) Multipurpose projects also provide facility for
afforestation and conservation of soil from erosion.
d) Hydroelectricity, the cheapest source of emery, is
produced from multipurpose projects. About 22% electricity comes from this
source in India.
e) Canals and reservoir can also be used for water
transportation and fisheries.
Disadvantage of Multipurpose Projects
a) Fertile agricultural land submerged under the river
water.
b) Large no. of people are displaced. They have to leave
their own houses and properties.
c) Forest land are either cleared or submerged under
water. It is great loss for environment.
d) Siltation in the dam reduces the life span of the
project.
e) Big multipurpose projects can result into minor
earthquakes.
Rainwater Harvesting and Its Objectives and Methods
Meaning: Capturing and storing the
rainwater for recharging the ground water is called rainwater harvesting. Rainwater
can also be used for domestic and agricultural purpose. It is a good method of
water conservation in water scarcity areas such as Rajasthan. Rainwater is
collected on the roof of house and it is stored in dug well or underground
tank. This water is used for washing, animal drinking, irrigation etc.
Objectives of Rainwater Harvesting
a) To reduce surface run-off which cause flooding on the
roads.
b) To meet the increasing demand of water.
c) To recharge the groundwater.
d) To reduce groundwater pollution and improve the
quality of water.
e) To supply water during dry season.
Methods of Rainwater Harvesting
a) Collecting rainwater on roof top and diverting it into
a dug well to recharge groundwater.
b) Collecting rainwater on roof and bringing it
underground tank in the house for domestic use.
c) Making small check dams to stop surface run-off and
allow the soil to absorb more moisture.
d) Using bamboo as pipe to bring spring water from far
away place for irrigation like in Meghalaya.
Different Methods of Rainwater Harvesting in India
- In Rajasthan,
rainwater is collected on the roof tank to store drinking water.
- Farmer of
Rajasthan collects rainwater in their agricultural fields to increase the
soil moisture. It is called ‘Khadins’ and ‘Johad’ in Rajasthan.
- People of
Rajasthan, also built underground tank [Called as ‘Tankas’] to store
drinking water for at least a year.
- In West Bangal,
people developed inundation channels to irrigate their fields.
- In the hilly
and mountainous areas, people build diversion channel called as ‘Guls’ and
‘Kuls’ for development of agriculture.
- Collection of
rainwater is also done in Shillong for household requirement.
- In Meghalaya,
people use bamboo [Bamboo Drip] as pipes to bring water spring water
located hundreds of meters away from the houses.
- Tamil Nadu is
the first state to make rooftop rainwater harvesting compulsory in every house
across the state.
Watershed Development:
An area drained by an tributary is called watershed. All round
development of this area is called watershed development. Sukhmajri Village in
Haryana is the best example of watershed development. Attempt made under
watershed development are:
- Conservation of
soil and moisture,
- Afforestation
and forest upgradation,
- Water
harvesting,
- Development of
horticulture
- Pasture
development
- Supply of
drinking water
CHAPTER 4: AGRICULTURE
Important Terms
- Agriculture: Cultivation of crops and domestication of
animals is called agriculture.
- Cash Crops: The crops which are cultivated for trade and
commerce and selling them in the market to earn money, like tobacco,
spices, fruits, sugarcane etc.
- Animal
Husbandry: Domesticating animals for
production of milk and meat is called animal husbandry.
- Green
Revolution: Sudden rise in the
production of crops by using HYV seeds, irrigation water, chemical
fertilizers etc. is called green revolution. It took place during 1960s in
our country.
- Horticulture: Cultivation of fruits and vegetables is called
as horticulture.
- Sericulture: Rearing of silk worm and producing silk is
called sericulture.
- Jhumming: Shifting agricultural in the north east is
called as jhumming. It is also called slash and burn agriculture because
tree are cut and burnt to clear the land for agriculture.
- PDS: It means Public Distribution System. It is a
program which provides foodgrains and other essential items [Rice, Wheat,
Sugar, Kerosene Oil etc.] to rural people at subsidized rate [low price].
- Minimum Support
Price [MSP]: It is a lowest
price announced by the Govt. at which foodgrains are procured by FCI [Food
Corporation of India].
- Genetic
Engineering: It means
developing new and hybrid seed by using modifying the gene of the crops.
- Shifting
Agriculture: It is also
called as slash and burn agriculture. In this agriculture forest land is
cleared and they are burnt. Agriculture is done using very old tools on
very small scale. After one or two year new land is selected and same
process is followed. This method of agriculture is very old; and gives
very low production; and also it degrade forest. In the north-east this
agriculture is called as jhumming or jhum cultivation.
- Important Crops
in India:
- Cereal Crops:
Rice, Wheat, Bajra
- Millets:
Jowar, Bajra and Ragi
- Pulses: Tur
[Arhar], Urad, Moong, Masur, Peas, Gram
- Oilseeds:
Mustard, Coconut, Groundnut, Coconut, Sunflower, Soyabean
- Beverage: Tea,
Coffee
- Fiber Crops: Cotton,
Jute, Hemp and Natural Silk
- Cash Crops:
Sugarcane, Rubber, Tobacco, Spices
- Operation Flood: It means sharp rise in the production of milk.
It is also called as White Revolution.
Important Features and Characteristics of Indian
Agriculture
a) Indian agriculture is subsistence in nature. It means
produce is consumed by the farmer itself.

§ Plantation agriculture was started by British in
India.
§ Generally it is done in hilly and sloppy area where
rainfall is high and water can drain easily.
§ Heavy dose of fertilizers, pesticides etc are required.
§ Efficient and fast transport and communication help
this farming to connect with market.
§ Important crops are tea, coffee, banana, spices,
rubber etc.
Technological and Institutional Reforms
Agricultural in India is thousands of year old. It is subsistence in
nature because farmers consume most of the produce by themselves. But because
of use of modern technology and institutional reform Indian agriculture is
becoming commercial. Green Revolution [Crops] and White Revolution [Milk –
Operation Flood] is the result of these two reforms.
Technological Reforms:
a) Wooden plough was replaced with tractors and tillers.
b) Drip irrigation and sprinklers are now used for
irrigation which irrigates more area in less water.
c) Use of chemical and bio fertilizers have increase
manifold. HYV Seeds, pesticide, insecticides are also used more.
d) Biotechnology has developed much genetically improved
variety of seed which are resistant to drought and pest. They give more
production also.
e) Farmers are now using TV, Radio, Newspapers and Cell
Phone to know about weather condition and according they plan agricultural
activities.
Institutional Reforms:
a) Zamindari system was abolished by the Government of
India.
b) Small fields were consolidated to make large fields.
c) Agriculture was the main focus in the first Five Years
Plan.
d) Kissan Credit Card [KCC], Personal Accident Insurance
Scheme [PAIS] was started by Govt. to help the Indian farmers.
e) Govt. also announces Minimum Support Price and has
abolished the role of middleman in the market.

Contribution of Agriculture to National Economy
a) Agriculture is the backbone of Indian Economy. About
63% people are directly dependent on agriculture for their livelihood.
b) About 40% of national income comes for agricultural
sector alone.
c) Agriculture also provides raw materials to many
industries e.g. sugar, textile, food and beverage industries.
d) It also has ensured food security. FCI procure crops
at minimum support price to stock. It also distribute among people under PDS
[Public Distribution System].
e) India export wheat, sugar, fruits, tea to foreign
countries and earn foreign exchange.
f) Agriculture also brings happy, prosperity and
development in rural economy.
Food Security and Methods of Ensuring Food Security
Food Security: Food is the basic requirement of all the people in the
country. But many people are not able to get sufficient meals at least two
times in a day. During natural disaster like earthquake, flood, drought there
is shortage of food all over the country. Food security is a method to ensure
at least minimum quantity of food for all the people round the year. Food
Corporation of India [FCI] procure foodgrains at Minimum Support Price and
maintain food security by two ways: a) Buffer Stock and b) Public Distribution
System [PDS].
Methods of Ensuring Food Security in India
a) More area should be brought under cultivation of
foodgrains like rice, wheat, pulses and oil seeds.
b) HYV Seeds should be used which gives more production
per hectare of land.
c) Biotechnology can be used to modify genetics of seed
so that it can resist drought, flood and diseases and give more production.
d) More multipurpose projects should be undertaken to
improve agriculture.
e) Modern machines and tools should be used in
agriculture like tractor, harvester, sprinklers etc.
f) Farmer should be given banking and insurance
facilities.
g) All forms of soil erosion should be checked and soil
should be conserved.
Globalization and Its impact on Indian Agriculture
Meaning: Integrating the national economy with the economy of other
countries of the world is called globalization. It has made cross-border flow
of money, technology and people very easy.
Positive Impact of Globalization
a) Indian farmers will have access to internal market.
They can sell their produce at international prices.
b) Capital investment from foreign countries will develop
the Indian agriculture.
c) Globalization will bring competitiveness among farmers
which will lead to commercialization of Indian agriculture.
d) Indian farmers can also use modern technology and
machineries which are now used only in foreign countries.
e) Globalization will also help in biotechnology and
genetic engineering in India.
Negative Impact of Globalization
a) Multinational Companies [MNCs] of developed countries
will exploit our farmers as Indian farmers are poor and illiterate.
b) Small farmers of India cannot compete with farmers of
developed nations.
c) Indian farmers may not get the international buyers as
quality of our crops is not as per the international standard.
d) Due to globalization, Indian farmers will try to grow
more cash crops and there will be shortage of food in our country.

Mineral and Its Classification
Meaning: Minerals are natural substance which has certain physical and
chemical properties like colour, hardness, texture, crystals etc. Minerals are
very important as most of the things we use in our lives are made of one or
other minerals. Minerals are mined from earth surface. There are about 2000
types of minerals identified so far but few of them are very important like
iron, cooper, mineral oil, bauxite etc. Minerals can be classified as under:
1] Metallic Minerals: Metals are obtained from them.
a) Ferrous [Contain
Iron]: Iron Ore, Manganese, Nickel, Cobalt
b) Non-Ferrous [No
Iron]: Copper, Lead, Tin, Bauxite
c) Precious [Costly]:
Gold, Silver, Platinum
2] Non-Metallic Minerals: Metals are not obtained from them.
Mica, Salt, Potash,
Limestone, Marble, Sandstone
3] Energy Minerals: These minerals provide us energy.
Coal, Petroleum and
Natural Gas
Mode of Occurrence [Where are minerals found?]
Minerals are found in the earth surface [crust]. They are extracted by
mining activities. Minerals take millions of year to form; therefore they are
called as non-renewable resource.
h) In the veins and lodes of igneous rock
and metamorphic rock important metallic minerals are found like cooper, zinc,
tin, lead etc.
i) Energy minerals such as coal, petroleum and natural
gas are found in the beds and layers of sedimentary rocks.
j) Alluvial deposits [also called as placer deposits]
contain very precious minerals like gold, silver, tin, platinum etc.
k) Ocean water also contains many minerals like salt,
magnesium, bromide etc.
l) Weathered materials of the rocks contain bauxite [aluminum].

Karnataka. Iron ore mined from Kudremukh [Largest deposit in the world]. Ore is
exported to USA and Europe.
d) Maharastra-Goa Belt: Goa and Ratnagiri are important
mining place of iron ore.
Coal, Its Types and Distribution
Coal is a type of fossil fuel and the most important source of energy in
our country. Coal is formed by burial of plants and animals in the rocks for
million of years. Coal is used for generating thermal electricity and for
smelting iron ore. Coal in India is found mainly in Gondwana Rocks
series of river Damodar, Mahanadi, Godawari etc. There are four types of coal
as per carbon content.

Cotton Textile Industry and Its Problems
- It is an
agro-based and the oldest industry in India. First cotton mill was
established in 1854 in Mumbai. At present, it the largest industry in our
country. There are about 1600 cotton textile mills in our country.
- Cotton textile
mills are mainly concentrated in Maharastra and Gujarat due to favourable
conditions. Important centres are Mumbai, Pune, Ahmedabad, Suar, Rajkot
etc. Other centres are Agra, Kanpur, Hugli, Chennai, Madurai etc.
- Cotton textile
is produced by three methods in India: a) Handloom, b) Power-looms and c)
Mills
- Cotton textile
industry involves ginning, spinning, weaving, dyeing, designing, tailoring
and packaging to produce readymade garments.
- India export
yarn and readymade garments to USA, Japan, UK, France, Nepal, Sri Lanka
etc.
- Cotton textile
industries are facing many problems such as: a) scarcity of good quality
cotton, b) main cotton growing area went to Pakistan, c) old machinery, d)
erratic power supply, e) low productivity of labour, f) tough competition
from synthetic fibers.
Iron & Steel Industry and Its Problems
- This industry
is called as basic industry because it provide raw material to many other
industries such as machine an tools, transport equipment, construction
material etc. It is also called as heavy industry because raw materials
[iron ore, coal, limestone] are bulky in nature.
- Iron ore mixed
with limestone is smelted in the blast furnace using coking coal to
produce pig iron. The ratio of iron ore, limestone and coking coal used in
4:2:1.
- Pig iron is
mixed with manganese, chromium and nickel which make it more stronger
steel.
- Most of the
steel plants are located in Chotanagpur region due to its favourable
conditions. At present there are 10 integrated iron and steel plants and
many small and mini plants. Important integrated steel plants are
Jamshedpur, Durgapur, Bokaro, Bhilai, Burnpur etc.
- India produces
about 33 million tons of steel every year even though per capita
consumption of steel is very low i.e. 32 kg. It is low because India has
low economic and industrial development.
- Today steel
industries in India are facing many problems: a) High cost of production,
b) Limited availability of coking coal, c) Low productivity of labour, d)
Irregular supply of energy, e) Raw materials are found in a certain pocket
of India only, f) Poor infrastructure like transport and communication
etc.
Jute Industries and Its Problems
- India is
largest producer of raw jute and jute goods. There are about 70 jute mills
in our country.
- First jute mill
was setup in Rishra [Kolkata] in 1859. Most of the jute mills are located
along Hugli River in West Bengal due to favourable condition.
- Jute is used in
making rope, bags, carpets etc. Bihar, UP, Assam and Tripura also have
jute miils.
- Jute industries
are facing problems like: a) main jute producing area went to Bangladesh,
b) high production cost, c) declining demand of jute in international
market, d) tough competition from synthetic fiber industry.
Why cotton industries are mainly concentrated in
Maharastra and Gujarat?
Cotton textile industries are located mainly in Maharastra [around
Mumbai] and Gujarat [around Ahmedabad] because of the following reasons.
a) Raw Materials: These areas have easy access to raw
material i.e. cotton. Maharastra and Gujarat are the largest producer of cotton
in India.
b) Favourable Climate: Humid climate is required for
cotton textile. Maharastra and Gujarat have humid climate as they are located
near to Arabian Sea. This climate is also good for cultivation of cotton.
c) Availability of Capital: Mumbai is the financial
capital of our country. It provides finance and capital to cotton textile.
d) Labour: Maharastra and Gujarat are heavily populated
area. Cheap labours are available in this region.
e) Transport and Communication: Mumbai, Ahmedabad, Surat,
Pune etc are well connected by road and rail with other part of the country.
Mumbai port is used to export readymade garments to European Countries.
Why iron and steel industries are located mainly in Chotanagpur
Region?
Most of important integrated steel plants are locate in Chotanagpur
region i.e in Jharkhand, Chattisgarh, Orrisa etc. It is because of the
following reasons:
a) Raw Material: Chotanagpur area is rich in iron ore. Iron ore is extracted from Singbhum,
Mayurbhanj, Kendujhar etc.
b) Energy: Coal is
used for smelting iron ore in the blast furnace. Coal is available from
Raniganj, Dhanbad, Jharia and Bokaro.
c) Cheap labour: Bengal, Bihar and Orissa have high density of population. Therefore,
cheap labour is available in this region.
d) Transport: This region
is well connected by road and railway with other parts of the country.
Nantional Highway 2, Delhi – Howrah and
Howrah – Mumbai rail route passes through this region.
e) Capital: Kolkata is
a megacity which provide capital, banking and insurance facility.
Jute industries are located mainly along Hooghly
River. Why?
There are 69 jute mills located in a 2 km broad belt along Hooghly
River. This area provides many favourable conditions required for this industry.
a) Raw jute is available for West Bengal. West Bengal is
the largest producer of jute.
b) Coal for energy is brought from nearby Raniganj
Coalfields.
c) Hooghly River provides water for washing and cleaning
jute.
d) Warm and humid climate is very favourable for
cultivation of jute and jute industry.
e) Kolkata is a metro city which provides capital and
market.
f) Hooghly River also provides cheap water transport.
Sugar industry is shifting from northern to southern
India. Why?
Earlier UP and Bihar were the main producer of sugarcane. Therefore,
most of the sugar mills were located in these two states only. But now, sugar
mills are shifting towards Maharastra and Karnataka because of following
reasons.
a) Per hectare production of sugarcane is higher in
southern India. Black soil is quite suitable for cultivation of sugarcane.
b) Sucrose content in the sugarcane is higher in
Maharastra and Karnataka. It means more sugar can be produced for less
sugarcane.
c) Mills and machines are new in southern states. New and
modern machines increase the productivity.
d) Crushing season for sugarcane is longer in southern
states.
e) Cooperative sugar mills are running successfully in
southern states.
Industrial Pollution and Environmental Degradation
a) Air pollution is caused by the emission of CO2,
Carbon Monoxide, Sulphur Dioxide etc. Chimneys of the industries produce heat
leading to Global Warming and Green House Effect. Use of CFC in various
industrial products depletes ozone layer which filters ultraviolet rays of the
sun.
b) Dumping of organic and inorganic industrial waste into
water bodies pollute the water. Industries which produce paper, pulp, chemical,
leather, acids, dyes, fertilizers etc generate lots of toxic waste which kills
the aquatic life.
c) High intensity sound generated by running machines,
siren, drilling, fans etc leads to noise pollution. It causes irritation,
hearing impairment, heart attack etc. among the nearby people.
d) Mining activity to get raw material for industries
also degrade the environment. Land degradation, deforestation, soil erosion,
water logging etc. of result of mining activities.
Measurement [Methods] for Controlling Environmental
Pollution and Degradation
a) Industries should be located with careful planning and
better design.
b) Quantity of smoke can be reduced by using oil instead
of coal.
c) Non-conventional sources of energy should be used
instead of fossil fuels.

CHAPTER 7: LIFELINE
OF NATIONAL ECONOMY
Important Terms
- Transport: Movement of people and goods from one place to
another place is called transport. Modes of transport are: a) Land [Road,
Rail, Pipeline], b) Water [Inland, Oceanic] and c) Air [Domestic,
International]
- Communication: Transfer of idea, message, and information from
one place to another place is called communication. Modes of communication
are TV, radio, cellphone, newspaper, magazines, internet. Communication
has two types: a) Print Media [Newspaper, Magazines] and b) Electronic
Media [TV, Radio, Internet].

transport such as rail, airport, seaport etc.
Indian Railway at a Glance
§ Indian railway is about 150 years old. First rail was
started in 1853 between Mumbai and Thane.
§ It connects State Capital with Capital of India. It
also connects major towns and cities, tourist places, mining centers, seaports,
airports etc.
§ There are about more than 7,000 stations on 63,000 km.
long railway tract.
§ Indian railway is divided into 16 zones for proper
administration.
§ Railways in India have three gauge system: a) Broad Gauge [1.676 m]
b) Meter Gauge [1.0
m]
c) Narrow Gauge [0.762
and 0.610 m].
§ There are various types of train running in India such
as Rajdhani, Shatabdi, Mail and Express, Local and Special Trains which carry
passengers.

natural gas, water or even milk. Solid items can also be transported after
making it ‘slurry’.
- Pipelines are
found from oil producing centers to oil refinery plants and from oil
refinery plants to the market [city].
- Minerals oil
from upper Assam is transported to Barauni and Allahabad oil refinery
through pipeline.
- Pipeline from
Salaya to Jalandhar via Mathura and Delhi is also very important pipeline.
- The longest
pipeline in India is H-B-J pipeline which connect Hazia, Bijapur and
Jagdishpur. It is about 1700 km. long.
