Water Resource


# Explain how water becomes a renewable resource.

-Three-fourth of the earth’s surface is covered with water, but only a small proportion of it accounts for freshwater that can be put to use.
-This freshwater is mainly obtained from surface run off and ground water that is continually being renewed and recharged through the hydrological cycle.
-All water moves within the hydrological cycle ensuring that water is a renewable resource.

# What is water scarcity and what are its main causes?
- Water scarcity is the shortage of water but it is not only associated with regions having low rainfall or those that are drought prone.
-The availability of water resources varies over space and time, mainly due to the variations in seasonal and annual precipitation, but water scarcity in most cases is caused by over- exploitation, excessive use and unequal access to water among different social groups.
- Pollution
- Deforestation         

:
#Compare the advantages and disadvantages of multi-purpose river projects.

- Excessive sedimentation at the bottom of the reservoir, resulting in rockier streambeds and poorer habitats for the rivers’ aquatic life.
-Dams also fragment rivers making it difficult for aquatic fauna to migrate, especially for spawning.
-It has great ecological consequences like salinisation of the soil.
- Increasing the social gap between the richer landowners and the landless poor.
- Many people loose their livelihood

Q.1. How have the growing population, industrialisation and urbanisation led to water scarcity ? Explain. [CBSE 2008 (D)]
Or
Explain any four reasons responsible for water scarcity in India.
[CBSE 2010(D), Sept. 2012]
Or
How have industrialisation and urbanisation aggravated water scarcity in India ?
[CBSE Sept. 2010, 14]
Or
Give three reasons for water scarcity in post independent India.
[CBSE Sept. 2010]
Or
‘Three-fourths of the earth’s surface is covered with water but there is still scarcity of water across the globe.’ Explain giving three reasons.
[CBSE 2011]
Ans. (i) Growing population : Growing population is one of the basic factors which is responsible for the scarcity of water. Most of our cities are facing this problem due to overpopulation. A large population means more water not only for domestic use but also to produce more food.
(ii) Commercialisation of agriculture : After the success of Green Revolution, our farmers are producing commercial crops. The commercial crops need more water and other inputs. Assured means of irrigation like tube wells and wells are responsible for the falling groundwater levels.
(iii) Industrialisation : The post independent India witnessed intensive industrialisation and urbanisation. Today, large industrial houses are common in the form of industrial units of many MNCs (Multinational Corporations). The ever increasing number of industries has made matters worse by exerting pressure on the existing freshwater resources. Industries, apart from being heavy users of water, also require power to run them. Much of this energy comes from the hydroelectric power.
(iv) Urbanisation : Urbanisation has also aggravated the problem of water scarcity. Most of our cities are overpopulated. Overpopulation leads to over- utilisation of the water resources, and also pollutes the existing resources.
Q.2. How do the multipurpose river projects affect the aquatic life? Explain.
Or
Explain the ecological problems being faced due to the multi-purpose river projects.
[CBSE 2013]
Ans. In recent years, the multi-purpose projects and large dams have come under great scrutiny and opposition for a variety of reasons :
(i) Regulating and damming of rivers affect their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir, resulting in rockier streambeds and poorer habitats for the rivers, as well as the aquatic life.
(ii) Dams also fragment rivers making it difficult for the aquatic fauna to migrate, especially for spawning.
(iii) The reservoirs that are created on the flood. Plains also submerge the existing vegetation and soil leading to its decomposition over time.
(iv) Irrigation has also changed the cropping pattern of many regions with farmers shifting to water intensive and commercial crops. This has great ecological consequences like salinisation of the soil.
Q.3. Explain the quantitative and qualitative aspects of water scarcity.
Or
Water is available in abundance in India even then scarcity of water is experienced in major parts of the country. Explain with four examples.
[CBSE 2008 (D)]
Ans. (i) Quantitative aspect : This aspect is related to the availability of water resources. The availability of water resources varies over space and time mainly due to variations in seasonal and annual precipitation. However, water scarcity in most cases is caused by over-exploitation, excessive use and unequal access to water among different social groups.
(ii) Qualitative aspect : Now, let us consider another situation where water is sufficiently available to meet the needs of the people, but, the area still suffers from water scarcity. This scarcity may be due to bad quality of water. Lately, there has been a growing concern that even if there is ample water to meet the needs of the people, much of it may be polluted by domestic and industrial wastes, chemicals, pesticides and fertilizers used in agriculture, thus, making it hazardous for human use.
Q.4. Why is there an urgent need to conserve and manage our water resources ? Mention three reasons. [CBSE 2012]
Or
Why is it necessary to conserve water resources in India ? Explain.
Or
Why is it essential to conserve, and manage our water resources ? Explain any three reasons.
[CBSE 2012]
Or
Why we should conserve our water resources ? Explain any three reasons.
[CBSE 2012,2014]
Ans. (i) Precondition for life : Water is necessary for life on earth. It is believed that life originated in water before it invaded land. Water is in fact a precondition of life.
(ii) Water essential for crops: Cultivation of crops depends on the availability of water. Water dissolves minerals and other nutrients in the ground. The roots of the plants draw this nutritious water for the soil. India is an agricultural country so availability of water is a must.
(iii) Water and industries : Industries need water as coolant, solvent, raw material, etc.
(iv) Water for daily life : Water is also used for drinking and domestic consumption. The growing urbanisation with its modern lifestyle has been demanding greater share of water day by day.
(v) Water an important component of ecosystem : Conservation of water is also important to prevent degradation of our natural ecosystems.
(vi) Water scarcity : It is essential to conserve and manage water because its overuse and misuse has lead to water scarcity.
Q.5. Examine the importance of the river valley projects in the development of hydel power and irrigational facilities in India.
Or
Give any four objectives of the multipurpose river valley projects.
[CBSE Sept. 2011]
Ans. (i) Generation of Power (electricity) :
These multipurpose projects are the main source of power generation. According to the Economic Survey, 2013, these produce more than 39,788.40 MW power. They provide us neat, pollution free and cheapest energy which is the backbone of industry and agriculture.
(ii) Flood Control : These projects control the floods because water can be stored in them. These projects have converted many ‘rivers of sorrows’ into ‘rivers of boon’. For example, the river Kosi.
(iii) Soil Conservation : They help to conserve the soil because they slow down the speed of water.
(iv) Irrigation : These projects are the main source of irrigation for our country. These irrigate the fields during the dry seasons. Many perennial canals have been dug and they irrigate dry areas.
Q.6. “In recent years, the multipurpose projects and large dams have come under great scrutiny.” Give reasons. [CBSE Sept. 2012]
Or
Mention any four disadvantages of multip-urpose projects.
[CBSE Sept. 2010, 2013]
Or .
How may the multipurpose river valley projects become harmful for the country ? Explain with four examples.
[CBSE 2008]
Or
Why are multipurpose projects facing resistance ? Explain with three reasons.
[CB$ESept.2010]
Ans. (i) Adverse effect on the fertility of the soil : Due to the construction of dams, there are no annual floods in the river. And
because of this, the soil of the downstream region does not get nutrient rich “silt”. This decreases the fertility of the soil.
(ii) Adverse impact on aquatic life: Due to the construction of dams on the rivers, the fish in the downstream area do not get sufficient nutrient material. Regulating and damming of rivers affect the natural flow of water causing poor sediment flow downward, and excessive sedimentation at the bottom of reservoir, resulting in rockier stream beds and poorer habitats for the rivers aquatic life. Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning i.e., to produce eggs.
(iii) Displacement of local communities: The building of large dams results in displacement of local communities. The local people often have to give up their land and livelihood and their meagre access and control over resources for the greater food of the nation.
(iv) Change in the cropping pattern: The multipurpose projects are responsible for providing assured means of irrigation to farmers. Due to this, most of the farmers have changed the cropping pattern shifting to water intensive and commercial crops. This has led to salinisation of soil leading to ecological imbalance.

(i) Name three states having black soil and the crop which is mainly grown in it.
(ii) What type of soil is found in the river deltas of the Eastern Coast? Give three main features of this type of soil.
(iii) What steps can be taken to control soil erosion in the hilly areas?
(iv) What are biotic and abiotic resources? Give some examples.
(i) The states of Maharashtra, Madhya Pradesh and Chhattisgarh have black soil. The crop which is mainly grown in this soil is cotton. This soil is also called ‘Regur’ or black cotton soil.
(ii) The river deltas of the eastern coast have alluvial soil.
Alluvial soil consists of various proportions of sand, silt and clay.
The main features of alluvial soil are:
(a) These soils are very fertile and so ideal for cultivation.
(b) They contain adequate quantities of potash, phosphoric acid and lime good for the growth of sugarcane, paddy, and other crops.
(c) In drier areas these soils are more alkaline.
(iii) In hilly areas, soil erosion can be controlled by contour ploughing which is ploughing along contour-lines, using terrace farming techniques and using strips of grasses to check soil erosion by wind and water.(iv)
Biotic Resources: The resources which are obtained from the biosphere and have life are called Biotic Resources. Examples of biotic resources are animals, plants, human beings, fish, livestock etc.
Abiotic Resources: The resources which are composed of non-living things are called Abiotic Resources.
Examples of abiotic resources are, water, minerals, metals, wind, solar energy etc.
Q3. Answer the following questions in about 120 words.
(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?
(ii) How have technical and economic development led to more consumption of resources?
1) Land resources in India are primarily divided into agricultural land, forest land, pasture and grazing land, and waste land. Waste land includes rocky, arid and desert areas, and land used for non-agricultural purposes like housing, roads, industry etc.
According to recent data available the percentage of net sown area (NSA) in India is about 54% of the total reporting area (if, the other than current fallow lands is included). . 22.5% is covered by forests, and 3.45% is used for grazing. The rest is waste land, with traces of miscellaneous cultivation.
Improper use of forest land has led to land degradation and made conservation of forests difficult.
Human activities like deforestation,overgrazing, mining , quarrying etc have contributed to the slow growth rate of forests. Thus, land under forest has increased by only about 4% since 1960-61.
(ii) The following factors have been responsible for technical and economic development leading to over consumption of resources .
In colonial times, imperial powers used their technological and economic superiority to establish control over other countries and thereby gain access to the latter’s resources. One country’s resources were accessible to the citizens of its colonial ruler too, leading to increased consumption.
Technical progress also results in efficient machinery, increased production and greater consumption of resources.
Technological development and economic progress has led to populations increasing due to low mortality at all ages. With new developments in medicine and health care, fewer people die due to accidents, diseases, in childbirth etc. This too has contributed to higher consumption of resources.
Q. 1. What is resource planning ? Mention the steps which are involved in resource planning. [CBSE 2009 (F); Sept. 2010, 14]
Or
Explain the three steps involved in the resource planning in India.
[CBSE Sept. 20W]
Or
What are the three stages of resource planning in India?
Ans. “Resource planning is a technique or skill of proper or judicious use of resources. ”
Resource planning is a complex process which involves :
(i) Identification and inventory of resources across the regions of the country. This involves surveying, mapping, 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.
Q. 2. Explain the classification of resources on the basis of exhaustibility. [CBSE 2009 (D), Sept. 2010, 2011]
Ans. (i) Renewable resources: “Renewable resources are the natural resources which can be used again and again or can be reproduced by physical, mechanical and chemical processes.” Solar energy, air, water and soil are some of the renewable resources of energy.
(ii) Non-renewable resources: “Non renewable resources are the natural resources that cannot be replaced at all or within a reasonable time.” Fossil fuels such as oil, gas and coal are examples of non renewable resources. These resources are accumulated over millions of years. They are considered to be non-renewable resources because once they are used up, they are gone forever.
Q. 3. Explain the classification of resources on the basis of origin.
Or
Give two examples of abiotic resources.
[CBSE 2010(F)]
Or
What are biotic and abiotic resources ? Give two examples for each.
[CBSE Sept. 2010]
Q- 4. Explain the classification of resources on the basis of ownership. [CBSE 2009 (O), 2014]
Or
Explain what is meant by national resources and individual resources.
[CBSE Sept. 2010, 2014]
Ans. (a) Individual Resources: Resources which are owned by private individuals are known as individual resources. Plots, fields, houses, cars, books, etc., are some examples of individual resources.
(b)Community Owned Resources : The resources which are accessible .to all the members of the community are known as community resources. Village ponds, public parks, playgrounds, etc., are some examples of community resources.
(c)National Resources: All the resources which are under the control of state or union government are known as national resources. All the resources within political boundaries are national resources because the government has the power to acquire even the private properties
(d)International Resources: These resources are owned and regulated by international institutions. 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. India has got the right to mine manganese nodules from the bed of the Indian Ocean from that area which lies beyond the Exclusive Economic Zone.
Q.5.Explain the classification of resources on the basis of the state of development. [CBSE 2008]
Or
Distinguish between stock resources and reserve resources.
[CBSE Sept. 2010,12]
Ans. (i) Potential Resources : Resources which are found in a region, but have not been utilised due to lack of capital or other reasons. For example: the western parts of India, particularly Rajasthan and Gujarat have enormous potential for the development of wind and solar energy, but so far, these have not been developed properly.
(ii) Developed Resources : These are resources which have been surveyed and their quality and quantity have been determined for utilisation. The development of resources depends on technology and the level of their feasibility. For example, India has a cumulative total of about 2,47,847 million tonnes of coal resources.

(iii) Stock : These are the materials in the environment which have the potential to satisfy the human needs but cannot be
used as the human beings do not have the appropriate technology to convert them into usable form. For example, water (H20) is a compound of two inflammable gases, i.e., hydrogen and oxygen, but human beings do not have the required technology to use them as a source of energy.
(iv) Reserves : These are the subset of the stock, which can be put into use with the existing technology, but their uses have been postponed keeping in mind the needs of the future generations. For example, India has sufficient amount of forests to fulfil the needs of the present generation, but they are being protected for the future generations.
Q. 6. Distinguish between Renewable and Non renewable resources. [CBSE Sept. 2010]
Q.7. HOW is land a natural resource of utmost importance ? Explain with four facts. [CBSE 2008 (O), 2012, 2013]
Or
“Land is a natural resource of utmost importance.” Elaborate the statement with the help of suitable examples highlighting the value of land resource.
[CBSE 2013]
Ans. Land is an important natural resource, because :
(i)All economic activities are performed on land.
(ii)It supports natural vegetation and wildlife.
(iii)Most of the minerals are formed in land.
(iv)It is used for transport and communication system.
Q-8. Which is the most widely spread and important soil of India ? State any six characteristics of this type of soil. [CBSE 2008 (F), Sept. 2010]
Or
Mention any four characteristics of alluvial soils.
Or
How are alluvial soils formed ? How is Bangar different from Khadar ?
[CBSE 2012]
Ans. Alluvial soil
Characteristics of the Alluvial soil :
(i) Alluvial soils are transported soils. Most of the soils are derived from the sediments deposited by rivers as in the Indo-Gangetic plain. Thus, the parent material of these soils is of transported origin.
(ii) These soils consist of varying proportion of sand, silt and clay. In the upper course of the river, the soil is coarse. In the middle course, it is medium, and fine grained in the lower course.
(iii) Apart from the size of their grains or particles, soils are described according to their age as well. They are old alluvium and new alluvium. Locally, the old alluvium is called ‘Bhangar’ and the new alluvium is called ‘Khadar’.
(iv) The old alluvium often contains ‘kankar, nodules, with calcium carbonates in the sub-soil. The new alluvium is more fertile than the old alluvium.
Q.9. Distinguish between Khadar and Bhangar.[CBSE 2010(0), Sept. 2010, 2011]
Q.10. Which soil is called ‘regur soil’ ? Mention
any four characteristics of this type of soil.
[CBSE 2009 (F), Sept. 2010, 2012, 2013]
Ans. Black soil
(i) These have been formed due to withering of lava.
(if) The black soils are made of extremely fine materials, i.e., clayey materials.
(iii)These soils are rich in soil nutrients such as calcium carbonate, magnesium carbonate, potash and lime.
(iv)These soils are generally poor in phosphoric content.
(v)The soil is well known for its capacity to hold moisture.
Q.11. How is red soil formed ? Mention its three characteristics. [CBSE Sept. 2010]
Or
How does red soil develop ? What makes it look red and yellow ?
[CBSE 2014]
Ans. Formation : Most of the red soils have come into existence due to weathering of ancient crystalline igneous rocks. Characteristics/Features :
(i) Soils are loamy in deep depressions and in uplands. They consist of loose gravels and highly coarse materials.
(ii)The colour of these soils is generally red, often grading into brown, chocolate or yellow. The red colour is due to wide diffusion rather than high percentage of iron content. It looks yellow when it occurs in a hydrated form.
(iii)Soils are deficient in phosphoric acid, organic matter and nitrogenous materials but are fairly rich in potash. But crops are cultivated with the use of fertilizers.
Q.12. Which geographical factors are responsible for the evolution of black soil ? Why is it considered the most suitable for growing cotton ? [CBSE 2012, 2013]
Ans. (1) Climatic conditions like temperature, rainfall etc. along with present rock material are important factors for making of black soil. The parent rock is volcanic rock.
(2) It is ideal for growing cotton because:
(i)It has capacity to hold moisture.
(ii)They are rich in calcium carbonate, magnesium, potash and lime.
(iii)This soil is also known as black cotton soil,
(iv) They develop deep cracks during hot weather, which help in the proper
aeration of the soil.
Q.13. How is mountain soil (forest soil) formed ? Mention any four characteristics of forest soil. .
Ans. Formation: The soils are formed due to mechanical weathering caused by snow, rain, temperature variation, etc. Characteristics/Features :
(i) These soils are heterogeneous in nature, and their character changes with mountainous environment and altitude.
(ii) The soils are very rich in humus, but are deficient in potash, phosphorus and lime.
(iii) The soils are especially suitable for plantation of tea, coffee, spices and tropical fruits.
(iv) The soil is loamy and silty in valley sides and coarse grained in the upper slopes. It is acidic with low humus content in the snow covered areas. It is fertile in the lower parts of the valleys.
Q.14. Mention any four features of the arid soils.
Or
Name the soil type which is widely found in Western Rajasthan. Explain two important characteristics of this soil type which make it unsuitable for cultivation. [CBSE 2012]
Ans. Arid soil is widely found in Western Rajasthan.
(i) The soil ranges red to brown in colour.
(ii) The soils contain considerable amount of soluble salts.
(iii) The soils contain a low percentage of organic matter due to dry climate and absence of vegetation.
(iv) The soil is alkaline in nature as there is no rainfall to wash soluble salts.
(v) The lower horizon of the soil is occupied by ‘kankar’ because of the increasing calcium content downwards. The ‘kankar’ layer formations in the bottom horizons restrict the infiltration of water.
(vi) The soils are infertile but with irrigation and
fertilizers, the drought resistant and salt tolerant dry crops such as barley, cotton, wheat, millets, maize, pulses, etc., are grown. (Any Four)
Q.15. Explain the formation and important features of the laterite soil. [CBSE 2013, 14]
Ans. Formation : It develops in areas with high temperature and heavy rainfall. The laterite soil is a result of intense leaching owing to heavy tropical rains.
Features :
(i) The soils are acidic in nature, coarser and crumbly in texture.
(ii) Due to lack of nitrogen, potassium and organic elements, the laterite soils lack fertility, and are not suitable for cultivation. But when the soils are manured and irrigated, some crops can be cultivated.
(iii) As the soils are indefinitely durable, so they provide valuable building materials.
Q.16. What is soil erosion ? Explain the major types of soil erosions prevailing in India. [CBSE Sept. 2010]
Ans. “Soil erosion is the removal of soil by the forces of nature like wind and water, more rapidly than the various soil forming processes can replace it.” Generally, there is a balance between the soil forming process and the erosional process. The balance can be disturbed by natural or human factors.
Types of Soil Erosion :
(a) Water Erosion : Water is a powerful agent of soil erosion. Following are the major types of erosion caused by water.
(i) Sheet Erosion : When the top layer of the soil is removed over a large area by the running water, it is called as sheet erosion.
(ii) Rill Erosion : This is the second stage of sheet erosion. If erosion continues unchecked for a sufficient time, (rills) or small finger-shaped grooves which are a few centimetres in depth, may develop on the landscape. Over a period of time, the fine rills increase in number and also become deeper and wider, and resemble the twigs, branches and trunk of a tree. This is called as rill erosion.
(iii) Gully Erosion : This is the third stage of sheet erosion. With further erosion of the soil, the rills may deepen and become enlarged, and are ultimately turned into gullies. The main cause of gully erosion is the removal of vegetation, particularly of trees with their widespread binding roots. Gullies cut up agricultural land and the entire area may be turned into a bad land
topography. Gully erosion is also responsible for the formation of ravines.
(b) Wind erosion : Wind is a powerful agent of erosion in arid and semi-arid lands with little rainfall. Wind can lift the valuable top soil from one area and deposits in another area. The wind erosion is very dangerous type of erosion because due to wind most of the deserts of the world are expanding.
Q.17. With reference to the types of soil, answer the following questions :
(i) Name any four regions or states where alluvial soil is formed.
[CBSE Sept. 2010]
(ii) Name any four regions or states where red and yellow soils are formed.
(iii) Name any four regions or states where laterite soil is formed.
Ans. (i) Rajasthan, Gujarat, deltas of Mahanadi and Godavari, and deltas of Krishna and Kaveri rivers.
(ii) Odisha, Chhattisgarh, Southern parts of the middle Ganga plain and the Western Ghats.
(iii) Karnataka, Kerala, Tamil Nadu and Madhya Pradesh.
Q-18. State two main differences between the Alluvial soil and the Red soil.
Q.19. Give reasons :
(i) Alluvial soil can hold moisture, and is very fertile.
(ii) Black soil needs to be tilled after the first rain.
(iii) Red soil is ideal for dry farming.
(iv) The percentage of organic matter in desert soil is very low.
(v) Red soil is less fertile.
Ans. (i) Because the alluvial soil is made up of fine particles. The soil is very fertile because it is rich in mineral nutrients like potash and lime.
(ii) The soil is sticky, and difficult to work unless tilled immediately after the first rain.
(iii) Because it does not require much moisture.
(iv) Because of the dry climate and absence of vegetation.
(v) Because it is deficient in phosphorus, nitrogen, lime and humus.
Q.20. Name two important crops associated with the following types of soil :
(a) Alluvial soil (b) Black soil
(c) Desert soil (d) Laterite soil
Ans. (a) Alluvial: Wheat and rice.
(b) Black: Cotton and sugarcane.
.(c) Desert: Barley and ragi.
(d) Laterite: Coffee and tea.
Q.21. Explain the land-use pattern of India.
Ans. (i) The net sown area in India has decreased from 45.26% to 43.41%. This means that more and more agricultural land is being shifted to other activities. This is not a healthy trend, and must be checked. The steps taken by government has resulted in increase of net sown area to 47% in 2005-06.
(ii) The pattern of the net sown area varies greatly from one state to another. It is over 80 per cent of the total area in Punjab and Haryana, and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and the Andaman and Nicobar Islands.
(iii) The area under forests has increased from 18.11% in 1960-61 to 22.57% in 2000-03 and to 23% in 2005-06 yet it is far below than the scientific norms.
(iv) The land under permanent pasture is very low, i.e., only 3.45% (Fallen to 3%). This shows the tremendous pressure of livestock population on agricultural land. Cattle are reared mainly on the farm wastes, grain chaff and a few fodder crops.
(v) Area under fallow land has also decreased which shows, that subsistence agriculture is being replaced by commercial agriculture.
(vi) A part of the land is termed as waste land, and land put to other non-agricultural uses. Waste land includes rocky, arid and desert areas, and land put to other non- agricultural uses includes settlements, roads, railways, industries, etc.
Q. 22. Explain any four proper fanning techniques which can be used for soil conservation.
Or
Suggest any three measures of soil conservation.
[CBSE Sept. 2010, 2011]
Or
What is soil conservation ? Explain any three methods of soil conservation suitable to Indian conditions.
[CBSE 2013, 14]
Ans. Soil conservation includes all those measures which help in protecting the soil from erosion or degradation.
(i) Crop rotation : If the same crop is sown in the same field, year after year, this consumes certain nutrients from the soil making it infertile. Crop rotation can check this type of erosion.
(ii) Settled agriculture : Checking and reducing shifting agriculture by persuading the tribal people to switch over to settled agriculture.
(iii) Terracing and contour bunding :
Terracing and contour bunding across the hill slopes is a very effective, and one of the oldest methods of soil conservation. Hill slope is cut into a number of terraces having horizontal top and steep slopes on the back and front. Contour bunding involves the construction of bank along the contour.
(iv) Strip cropping : Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. This method is known as strip cropping.
(v) Shelter Belt : Planting lines of trees to create shelter also works in a similar way. Rows of such trees are called shelter belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in establishing the desert in western India

Federalism

Q.1. Explain the major key features of federalism.
Or
Describe any four features of the federalism.
[CBSE 2011, 14]
Ans. (i) Two or more levels of government :
Federalism is a system of government in which the governmental power is divided between a central authority and its various constituent units. Usually, a federation has two levels of government. One is the government for the entire country, and the other governments at the state or provincial level. ,
(ii) Same Citizens Separate jurisdiction : Different tiers of the government govern the same citizens, but each tier has its own jurisdiction in specific matters of legislation, taxation and administration.
(iii) Superiority of Constitution : The jurisdictions of the respective levels or tiers of the government are specified in the Constitution. So the existence and authority of each tier of the government are constitutionally safeguarded. ‘
(iv) Rigid Constitution : The fundamental provisions of the Constitution cannot be unilaterally changed by one level of the government. Such changes require the consent of the both the levels of the government.
(v) Supreme authority of the courts : Courts have the power to interpret the Constitution, and the powers of different levels of the government. The highest court acts as an umpire in case of disputes arising between different levels of the government in the exercise of their respective powers, (of) Dual objectives : The federal system,
thus has dual objectives : to safeguard and promote the unity of the country, while at the same time, to accommodate the regional diversity.
Q.2.Distinguish between the Coming Together Federations and the Holding Together Federations. [CBSE 2012, 14J]
Description: cbse-social-sciences-civics-class-10-federalism-laq.2
Q.3. ‘India is a federal country.’ Explain by giving examples.[CBSE Sept. 2012, 2013]
Or
Explain the three fold distribution of legislative powers between the Union Government and the State Governments.
Or
Mention any five main features which make India a federal country.
[CBSE 2013]
Ans. (i) Division of powers : The Constitution demarcates the powers of the central and the state governments into different lists of subjects. There are three lists :
(i) Union List.
(ii) State List.
(iii) Concurrent List.
(ii) Three-tier system : As discussed earlier, under a federal government different tiers of the government govern the same citizens. This is true for India. In India, we have a three-tier system of government, i.e.,
• Union Government
• State Government
• Local Self-Government.
(iii) Not equal powers to all administrative units : Most of the federations that are formed by ‘holding together’ do not give equal powers to its constituent units. Thus, all states in the Indian Union do not have identical powers. Some states enjoy a special status. Jammu and Kashmir has its own Constitution. Many provisions of the Indian Constitution are not applicable to this state without the permission of the state assembly.
(iv) Consent of both the levels of the government : Under a federal government, the fundamental provisions cannot be unilaterally changed by one level of the government, and the same is true for India. The Parliament cannot on its own change the fundamental structure of the Constitution.
implementation of constitutional provisions and procedures. The same is true for India. In case of any dispute about the division of powers, the High Courts and the Supreme Court take a decision.
(vi) Separate sources of income : A clear mention regarding the financial powers of the centre and the states has been made in the Indian Constitution. Income tax, excise duty, corporation tax, etc., are levied and collected by the central government, whereas land revenue, stamp duty, building tax, etc., come under the state government.
Q.4. How is federalism practised in India ? Explain.
Or
‘The real success of federalism in India can be attributed to the nature of democratic politics in India.’ Explain.
Ans. (i) Linguistic States : After independence, in 1950, the boundaries of several old states were changed in order to create new states. This was done to ensure that the people who spoke the same language, share common culture, ethnicity or geography could live in the same state.
(ii) Language Policy : The Indian Constitution did not give the status of national language to any one of the languages. Though Hindi was identified as the optional language, but the central government has not imposed Hindi on states where people speak a different language. Besides Hindi, there are 22 other languages recognised as Scheduled Languages by the Indian Constitution.
(iii) Centre-State relations : Improving the Centre-State relations is one more way in which federalism has been strengthened in practice. Though Indian Constitution has demarcated the powers of the Union and the state governments but still the Union government can have influence over the state in many ways.
In the past, the Central government has often misused the Constitution to dismiss the state governments that were controlled by
rival parties. This undermined the spirit of federalism, and that of democracy.
The judiciary has played a major role in improving the autonomy of the state governments because many a time, it has rescued state governments which were dismissed in an arbitrary manner.
Q.5. “The creation of linguistic states was the first and major test for democratic politics in our country.” Justify this statement. [CBSE 2011, 14]
Ans. In 1947, the boundaries of several old States of India were changed in order to create new States. This was done to ensure that people who spoke the same language lived in the same State. Some States were created not on the basis of language but to recognize differences based on culture, ethnicity or geography. These include States like Nagaland, Uttarakhand and Jharkhand. When the demand for the formation of States on the basis of language was raised, some national leaders feared that it would lead to the disintegration of the country. The Central Government resisted linguistic States for some time. But the experience has shown that the formation of linguistic States has actually made the country more united. It has also made administration easier.
Q.6. Explain how law making powers are  shared between centre and states in India ? Mention three subjects each of Ans. Union List and State List. [CBSE 2013]
Or
Describe the division of power between the central and the state governments in India.
[CBSE 2011]
Or
How are the powers divided between the states and centre ? Explain with examples.
Ans. Union List includes subjects of national importance such as defence of the country, foreign affairs, banking, communications and currency. They are included in this list because we need a uniform policy on these matters throughout the country. The Union Government alone can make laws relating to the subjects mentioned in the Union List.
State List contains subjects of State and local importance such as police, trade, commerce, agriculture and irrigation. The State Governments alone can make laws relating to the subjects mentioned in the State List. Concurrent List includes subjects of common interest to both the Union Government as well as the State Governments, such as education, forest, trade unions, marriage, adoption and succession.
Both the Union as well as the State Governments can make laws on the subjects mentioned in this list. If their laws conflict with each other, the law made by the Union Government will prevail.
(i) Under a federal government, the fundamental provisions cannot be unilaterally changed by one level of the government and the same is true for India,
(ii) The Parliament cannot on its own change the fundamental structure of the Constitution. Any change in it has to be first passed by both Houses of the Parliament with at least two-third majority. Then it has to be ratified by the legislatures of at least half of the total states.
Q.7. Distinguish between the Union List and the Concurrent List.
Description: cbse-social-sciences-civics-class-10-federalism-laq.7
Q.8. ‘Most federations that are formed by ‘holding together’ do not give equal power to its constituent units.’ Is it true for India ? Explain.
Or
“Holding together federations” do not give equal power to its constituent units. Explain the statement with the help of examples in context to India.
[CBSE 2012]
Ans. Yes, the above statement is true for India.
(i) All states in the Indian Union do not have identical powers. Some states enjoy a special status. Jammu and Kashmir has its own Constitution. Many provisions of the Indian Constitution are not applicable to this state without the permission of the state assembly. Indians who are not permanent residents of this state cannot buy land or house here.
(ii) Similar special provisions exist for Assam and the hill states of North-East India.
(iii) There are some units of Indian Union which enjoy very little power. These are areas which are too small to become an independent state but which could not be merged with any of the existing states. These areas, like Chandigarh, or Lakshadweep or the capital city of Delhi, are called the Union Territories. These territories do not have the powers of a state. The central government has special powers in running these areas.
Q.9. Why were the linguistic states created? What are their advantages ? [CBSE 2008 (Compt)]
Ans. (i) Common Language: Many states were created on the basis of language to ensure that people who speak the same language lived in the same state.
(ii) Common culture, ethnicity or geography: Some States were created not on the basis of language but to recognise differences based on culture, ethnicity or geography. These include States like Nagaland, Uttarakhand and Jharkhand.
Advantages :
• The experience has shown that the formation of linguistic States has actually made the country, more united. It has also made administration easier.
Q.10. Explain the language policy of Indian Federal. How is it different from Sri Lanka ?
Or
Write any four characteristics of language policy of India.
[CBSE 2011]
Or
Describe in brief the language policy of India.
[CBSE 2010]
Ans. (i) No National Language: Our Constitution did not give the status of national language to any one language. Hindi was identified as the official language. But Hindi is the mother tongue of only about 40 per cent of Indians. Therefore, there were many safeguards to protect other languages.
(ii) Scheduled Languages: Besides Hindi, there are 22 other languages recognised as Scheduled Languages by the Constitution. A candidate in an examination conducted for the Central Government positions may opt to take the examination in any of these languages. States too have their own official languages. Much of the government work takes place in the official language of the concerned State.
(iii) Spread of Hindi with cautious approach: Unlike Sri Lanka, the leaders of our country adopted a very cautious attitude in spreading the use of Hindi. According to the Constitution, the use of English for official purposes was to stop in 1965. However, many non-Hindi-speaking States demanded that the use of English continue. In Tamil Nadu, this movement took a violent form. The Central Government responded by agreeing to continue the use of English along with Hindi for official purposes. Promotion of Hindi continues to be the official policy of the Government of India. Promotion does not mean that the Central Government can impose Hindi on States where people speak a different language.
(iv) Language policy of Sri Lanka: In 1956, an Act was passed by the Sri Lankan government to recognise Sinhala as the only official language whereas in case of India the government agreed to continue the use of English along with Hindi for official purposes.
Q.11. ‘Restructuring the Centre-State relations is an important way in which the Indian Federalism has been strengthened in practice.’ Explain.
Ans. (i) After 90s, many regional political parties have emerged in many states of the country.
(ii) The regional parties are playing a very vital role in forming the Union government.
(iii) The judiciary has played a major role in improving the autonomy of the state governments because many a time, it has rescued the state governments which were dismissed in an arbitrary manner.
Q.12. Why does the exact balance of power between the Centre and the State Governments vary from one Federation to another ? Explain with two examples. [CBSE 2008(D)]
Ans. The exact balance of power between the central and the state government depends mainly on the historical context in which the federation was formed. There, are two kinds of routes through which federations have been formed :
(i) Coming Together Federations
(ii) Holding Together Federations
[Refer Q. 2, Long Answer Type Questions]
Q.13. Point out one feature in the practice of federalism in India that is similar to any one feature that is different from that of Belgium.
Ans. One similar feature of Federalism between India and Belgium : India and Belgium are both holding together federations where the Central Governments tend to be more powerful vis-a-vis the states.
One different feature of Federalism between India and Belgium : In Belgium, there are three Ans. kinds of government – government at the centre, government at the state level and third kind of government is the community government. The community government has the power regarding cultural, educational and language related issues.
But in India, there is no third kind of government, there is no community government.
Q.14. What is decentralisation ? What is the importance or need for decentralisation ? [CBSE Sept. 2010, 14]
Or
“Do you take decentralisation as a mean to minimise the conflicts ?” Give your view point.
[CBSE 2014]
Ans. When power is taken away from the Central and State governments, and given to the Local governments, it is called decentralisation.
(i) The basic idea behind decentralisation is that there are a large number of problems and issues which are best settled at the local level. People have a better knowledge of problems in their localities. They also have better ideas on where to spend money, and how to manage things more efficiently.
(ii) At the local level, it is possible for the people to directly participate in decision, making. This helps to inculcate a habit of democratic participation. Basically the local government is the best way to realise one important principle of democracy, namely the Local Self-Government.
Q.15. Name the three tier government system in India. What steps have been taken by the government to make the third tier more powerful and effective ? [CBSE 2008(0)]
Or
How has the third tier of government in our country been made more effective and powerful by the Constitutional Amendment of 1992 ?
[CBSE Sept. 2010]
Or
Explain any four provisions that have been made towards decentralisation in India after the constitutional amendment in 1992.
[CBSE Sept. 2010, 2011, 2012]
Ans. Three tier system :
1. Union Government
2. State Governments
3. Local Governments.
Steps :
• Now, it is constitutionally mandatory to hold regular elections to the local government bodies.
• Seats are reserved in the elected bodies and the executive heads of these institutions for the Scheduled Castes, Scheduled Tribes and the Backward Classes.
• At least one-third of all positions are reserved for women.
• An independent institution called the State Election Commission has been created in each state to conduct free and fair elections for the panchayat and the municipalities.
• The State governments are required to share some powers and revenue with the Local government bodies. The nature of sharing varies from state to state.
Q.16. Explain the advantages of decentrali¬sation. [CBSE Sept. 2010, 14]
Or .
Explain any four features of the third tier of government.
[CBSE Sept. 2011]
Or
Explain how the federal experiment has been successful in the matter of formation of states in India.
[CBSE Sept. 2010]
Or
Give two arguments in favour of decentralisation of powers to local governments. Give two provisions under the amendment of 1992 which empowers local governments in India.
[CBSE Sept. 2011]
OR
Assess the need for local government.
[CBSE 2012, 14]
Ans. (i) Locals have better knowledge : The basic idea behind decentralisation is that there are a large number of problems and issues which are best settled at the local level. People have better knowledge of problems in their localities. They also have better ideas on where to spend money, and how to manage things more efficiently.
(if) Direct participation of the people : Decentralisation makes it possible for the people to directly participate in decision making. This helps to inculcate a habit of democratic participation. The Local government is the best way to realise one important principle of democracy, namely the Local Self-Government.
(iii) Foundation of democracy : Local governments are most important in a democratic system. These are training schools for local citizens and local leadership. These provide political education. The people get familiar about the electoral process, and the proper use of their vote, which is the very foundation of democracy.
(iv) Reduction of burden of the Central Government : It reduces the burden of the Central or State governments. These can concentrate on matters of national or state importance in a better way. In this way, the Local Self-Government ensures efficiency everywhere, at all the three levels of today’s governance. Indian leaders have recognised the need for decentralisation.
(v) Women empowerment : At least one-third of all positions are reserved for women in all the local bodies. This has lead to women empowerment.

Question-1
What is Federalism?
Solution:
Federalism is the advocacy of federal political orders, where the final authority is divided between sub-units and a centre. Unlike a unitary state, sovereignty is constitutionally split between at least two territorial levels so that units at each level have final authority and can act independently of the others in some area. In such a case citizens have political obligations to two authorities. The allocation of authority between the sub-unit and centre may vary.
The federal system thus has dual objectives that is to safeguard and promote unity of the country and accommodate regional diversity.
Governments at different levels should agree to some rules of power sharing. An ideal federal system has both aspects; mutual trust and agreement to live together.
Question-2
What makes India a Federal Country?
Solution:
India is a nation with many languages, religions and regions. It emerged as an independent nation after a long and painful partition. Several princely states became a part of the country soon after independence. India was declared as a Union of States, by the Constitution.
The Indian Union is based on the principles of federalism. The Constitution earlier provided a two-tier system of government, the Union Government (Central Government), representing the Union of India and the State governments. Later, Panchayats and Municipalities were added as a third tier of federalism. All these different forms of government enjoy separate jurisdiction.
Question-3
Write a brief note on the language policy adopted in India.
Solution:
The ‘Language policy’ was the second test for Indian federation. No language was given the status of national language by our Constitution. Hindi was identified as the official language. But only about 40 per cent of Indians have Hindi as their mother tongue. Therefore, 21 other languages besides Hindi, are recognised as Scheduled Languages by the Constitution. A candidate in an examination conducted for the Central Government positions may opt to take the examination in any of these languages.
States too have their own official languages. Much of the government work takes place in the official language of the concerned State.
The flexibility shown by Indian political leaders helped our country avoid any conflict based on languages.
Question-4
Write a brief note on village councils.
Solution:
Village Councils looked after the affairs of the village, had police and judicial powers and were the lines of contact with higher authorities on matters affecting the villages. Custom and religion elevated them to a sacred position of authority.
These Councils were the pivot of administration, the centre of social life, and, above all, a focus of social solidarity.
Question-5
What are the dual objectives of Federalism?
Solution:
The dual objectives of Federalism are to safeguard and promote unity of the country and to accommodate regional diversity.
Question-6
What are the duties of a Central and State governments?
Solution:
The duties of the Union or Central Government include subjects of national importance such as defence of the country, foreign affairs, banking, communications and currency. This is because, a uniform policy on these matters will be maintained throughout the country. All the laws pertaining to the above duties must be given only by the Union Government.
The duties of the State Governments include subjects of the State and local importance such as police, trade, commerce, agriculture and irrigation. All the laws pertaining to the above duties must be given only by the State Governments.
Some aspects have to be taken care of, by both, the Union Government as well as the State Governments. They are education, forest, trade unions, marriage, adoption and succession. Both governments can make laws on these subjects. If their laws conflict with each other, the law made by the Union Government will prevail.
Question-7
What is the special status the state of Jammu and Kashmir enjoys?
Solution:
Jammu and Kashmir enjoys a special status. It has its own Constitution. Many provisions of the Indian Constitution are not applicable to this State without the approval of the State Assembly. Indians who are not permanent residents of this State cannot buy land or house here. Similar special provisions exist for some other States of India as well.
