Maharashtra State Board Class 12 Geography Notes Chapter 8 Geography: Nature and Scope

→  The nature of the earth’s surface is full of variations. There are various features with variations such as mountains, hills, plains, plateaus, oceans, rivers, lakes, deserts, etc.

→  In geography, we study climatic patterns on the global and local level, its impact on vegetation and wildlife, wind patterns, soils and its types, etc.

→  Types of landforms, submarine relief, ocean currents, salinity, etc., are also studied by a geographer.

→  All the above-mentioned physical aspects affect human populations.

→  Such variations bring about changes in social and cultural features too, which changes from place to place and time to time.

→  Variations are also observed in the form of settlements, transportation networks, markets and ports and many other elements developed by man during the entire period of man’s cultural development.

→  Taking into consideration the above all factors, the subject matter of geography can be divided into two major themes – Physical Factors and Human Factors. Thus, giving rise to two branches in Geography – Physical Geography and Human Geography.

→  Human Geography studies relationship between man and environment.

→  It also studies distribution attributes related to man’s social and environmental phenomena around the world.

Nature of Geography as a discipline

• The earth is dynamic. Hence, there are variations in its physical and cultural environments.
• Geography is a study of the earth and phenomena related to it.

Geographers study –

→ Through scientific and supplemental methods with experiments, data collection, observation patterns, data analysis and research.

→ Geographical distributions, their patterns and variations as well as the causes behind these phenomena.

→ Geographical distributions of various crops in different regions. Thus, understanding the impact of climate, soil, market demand and application of technology to identify the differences.

→ The space, area, region and geographical location. Skills and techniques used in study of geography make it empirical and practical in nature.

→ Skills developed by geographers enables them to make observations and describe various phenomena on the earth; and enriched the subject and newer branches of geography went on developing.

→ There are two contrasting approaches to study geography, which is known as Dualism in geography.

There are two contrasting approaches in Geography –

1. Nature is more dominant than man, which is called Environmental Determinism.
2. Man dominates nature, which is called Possibilism.

→  Since there are many such dualistic approaches in geography; it makes geography dualistic in nature.

Scope of Geography

→ Almost every discipline, under natural and social sciences, is linked with Geography.

→ Therefore, geography has a very strong interface with natural and social sciences.

→ Since many branches of geography have developed from mainstream disciplines geography has become an interesting and interdisciplinary subject.

Latest Trends in Geography:

• Geographer explains the phenomena within the frame of cause and effect relationship.
• It helps to analyse and predict future through data collection and modelling.
• This results in intra and inter-disciplinary avenues and widens the scope of geography and its dynamic nature of adding new subjects.

The following are uses of geographical models:

• Population growth and density
• Land use
• Intensity of cropping
• migration patterns of population
• Industrialization
• urbanization
• Growth of cities
• Growth of Slums

By going through these Maharashtra State Board Class 12 Economics Notes Chapter 4 Supply Analysis students can recall all the concepts quickly.

Maharashtra State Board Class 12 Economics Notes Chapter 4 Supply Analysis

Terms related to Production and Supply:

→ Producers undertake the production of goods and services which earn profit from them. They supply more goods and services at a higher price to earn profit. Like demand, supply is related to price and is also an important factor that determines the market price. Demand and supply are interrelated aspects of the market.

→ Supply is the outcome of stock and stock is the outcome of production. So, it is important to understand supply and its related concepts like production, stock, supply, etc.

→ Production implies the creation of utility, with the help of land, labour, capital, and organization. Production results in an output of goods.

→ Output is the outcome of the process of production in a given time in the economy with the help of factor inputs.

→ Stock is the total quantity of commodity available to the producer for sale at a point in time. Stock determines potential supply.

→ Reservation price is the seller’s minimum price below which the seller is not willing to sell even a single unit. If the market price is more than the reservation price then the seller will be willing to offer his stock for sale from his stock and vice versa. Usually, reservation price is low in the case of perishable goods and high in the case of durable goods.

Definition of Supply:
Supply in defined as “the quantities of a commodity that a seller is willing and able to offer for sale at a given price, during a certain period of time”. He sells more at a higher price and less at a lower price. Supply analysis may be of individual supply or market supply.

Individual Supply:
It refers to various quantities of a commodity an individual seller or producer is willing to sell at different prices. This can be shown by the individual supply schedules.

Individual Supply Schedule: It is a tabular representation of various quantities of a commodity that produce is willing to offer for sale at different prices during a given period of time as shown below.

Individual Supply Curve: It is a graphical representation of an individual supply schedule. It slopes upwards from left to right showing direct relationship between price and quantity supplied as shown on next page :

Market Supply:
It is the sum total of individual supply. It refers to various quantities of a commodity offered by all the sellers for sale at different prices during a given period of time. It can be shown by market supply schedule or market supply curve.

Market Supply Schedule: It is a tabular representation of various quantities of a commodity offered for sale by different sellers at different prices during a given period of time. It is obtained by horizontal summation of all individual supply as shown below.

Market Supply Curve: It is a graphical representation of market supply schedule. It slopes upwards from left to right indicating direct relationship between price and quantity supplied as shown below.

Determinants of Market Supply:

→ Price of the Commodity – Price increases, Supply decreases and vice versa.

→ Cost of Production – Cost of Production increases – Supply decreases and vice versa.

→ Technique of Production – Advanced technology, Supply increases and Outdated technology, supply decreases.

→ Government Policy – Favourable government policy, supply increases and vice versa.

→ Exports and Imports – More exports, supply decreases, more imports, supply increases.

→ Future expectation – Fall in price expectation, supply decreases and vice versa.

→ Climatic Conditions – Favourable climatic conditions, supply increases and vice versa.

→ Nature of Market – Short period market, supply decreases, Long-period market, supply increases.

→ Infrastructure Facility – Well connected infrastructure, supply increases and vice versa.

→ Price of other goods – Price of substitute goods increases, supply increases, and vice versa.

→ Natural and Man-made Calamities – Natural calamities, reduction in supply.

Law of Supply:
According to Prof. Alfred Marshall, “Other things remaining constant, higher the price of the commodity, greater is the quantity supplied and lower the price of the commodity, smaller is the quantity supplied. ”
In other words, quantity supplied of a commodity varies directly with price.

Symbolically, it is expressed as S = f (P) [S = Supply, P = Price, f = Function of]
The law can be better understood with the help of a market supply schedule and market supply curve.

Market Supply Schedule: It is a tabular representation of various quantities of a commodity offered for sale by different sellers at different prices during a given period of time. It is obtained by horizontal summation of all individual supply as shown below.

Market Supply Curve: It is a graphical representation of market supply schedule. It slopes upwards from left to right indicating direct relationship between price and quantity supplied as shown below.

Assumptions of the Law of Supply:

1. No change in Cost of Production
2. No change in Technique of Production
3. No change in Weather Condition
4. No change in Government Policies
5. No change in Transport Cost
6. No change in the quantity of goods kept for self-consumption
7. No change in Price of Competitive goods
8. Constant Scale of Production If all these factors do not change, then more will be supplied at higher price and vice-versa.

Exceptions to the Law of Supply:
In following cases, more may not be supplied at higher price and vice-versa.

• Labour supply
• Savings
• Future expectations
• Urgent need for cash
• Rare goods
• Agricultural goods
• perishable goods

Variation in Supply:
When quantity supplied of commodity changes due to change in its price, other factors remaining constant, it is known as Variation in supply. It can be of two types :

(A) Expansion or Extension in Supply : When quantity supplied rises due to an increase in the price of a commodity, other factor remaining constant, it is called expansion or extension in supply. It is shown by an upward movement on the same supply curve.

When price rises from 0P to 0P₁ supply in the market also rises from 0Q to 0Q₁( Hence it is shown by upward movement on the same supply curve.

(B) Contraction in Supply : When quantity supplied falls due to fall in the price of a commodity other factors remaining constant, it is called contraction in supply. It is shown by downward movement on the same supply curve.

When price falls from 0P to 0P₂, supply in the market also falls from 0Q to 0Q₂. Hence this is shown by downward movement on the same supply curve.

Changes in Supply :
When the quantity supplied of a commodity changes due to factors other than price, it is known as change in supply. It can be of two types :

(A) Increase in Supply : When more quantity is supplied at the same price due to changes in factors other than price, it is called increase in supply. It takes place when, there is decrease in price of inputs, more imports, technological up gradation, fall in taxes, etc. It is shown by shift of the supply curve to the right of original supply curve.

When at the same price 0P, quantity supplied rises from 0Q to 0Q₁ it is called increase in supply.

(B) Decrease in Supply : When less quantity is supplied at the same price, due to change in factors other than change in price it is called decrease in supply. It takes place when there is increase in price of inputs, old technological, more taxes, etc. It is shown by a shift of the supply curve to the left of original supply curve.
When at the same price 0P, quantity supplied falls from 0Q to 0Q₂, it is called decrease in supply.

Concepts of Cost and Revenue :

(A) Concept of Cost: Cost of production means the aggregate money expenditure incurred by a firm on various inputs like land, labour, capital, etc. in the form of rent, wages, interest, transport, insurance, etc. There are three main types of cost TC, AC and MC.

Total Cost (TC): It is the total expenditure incurred by a firm on the factors of production required for the producing of goods and services. It is the sum total of Total Fixed Cost (TFC) and Total Variable Cost (TVC). Hence, TC = TFC + TVC

• Total Fixed Cost (TFC):
  It is the cost incurred on fixed factors of production like land, factory, building, capital, etc.
• Total Variable Cost (TVC):
  It is the cost incurred on variable factors like labour, raw material, electricity, etc.

Average Cost (AC): It refers to per unit total cost of production. It is obtained by dividing Total cost by number of units of that commodity produced.
Hence, AC = \(\frac{\mathrm{TC}}{\text { Total output }}\)

Marginal Cost (MC): It is net addition made to the total cost by producing one more unit of output.
Hence, MCn = TC_n – TC_{n -1} (n = Number of unit produced)

(B) Concept of Revenue :
Revenue refers to the amount received by a firm from the sale of given quantity of commodity in the market at different prices. Hence, Revenue = Price x Quantity Sold

The concepts of Revenue consists of three types :

1. Total Revenue (TR),
2. Average Revenue (AR),
3. Marginal Revenue (MR).

Total Revenue (TR): Total Revenue refers to total receipts of the firm from its sales of commodity. It is obtained by multiplying the price per unit of the commodity with total number of units sold.
Hence, TR = Price x Quantity Sold

Average Revenue (AR): It refers to the revenue per unit of the commodity sold.
Hence, AC = \(\frac{\mathrm{TR}}{\text { Total quantity sold }}\)

Marginal Revenue (MR):
Marginal revenue is the net addition made to TR by selling an additional unit of the commodity.
Hence, MR_n = TR_n – TR_n-1 (n = Number of units sold).

By going through these Maharashtra State Board Class 12 Geography Notes Chapter 7 Region and Regional Development students can recall all the concepts quickly.

Maharashtra State Board Class 12 Geography Notes Chapter 7 Region and Regional Development

→ Natural (physical) or man-made (administrative boundaries, political or linguistic) feature of a small or large area of land having common features help us to identify them separately.

→ Demarcated boundary separates one region from the other. The geographical area that distinguishes itself from another area is called a region.

→ The classification of regions is based on common characteristics and is homogeneous in nature, which constitutes of a region.

→ A region is a basic unit in any geographical studies and helps us to differentiate one area from another.

Types of regions

→  Formal regions and functional regions are the two types of regions.

→  A formal region is an area inhabited by people who have one or more characteristics in common.

→  On the basis of characteristics, a formal region is divided into a physical region or political region.

→  A functional region is an area organized to function socially and economically as a single unit.

→  Functional region involves more than one type of physical or political regions.

Factors affecting regional development

→  Development is a relative term. Therefore, while considering regional development the physical, economic, social, environmental aspects of a region are taken into consideration.

Physical factors and regional development

→ Regional development is affected by physical factors like climate and relief of the region.

→ Areas where land is less fertile, water is scarce and diseases flourish will be less developed.

→ A region with a large number of resources, but climate is not suitable, or lack of population to exploit resources, the region will not develop.

Population and regional development

• Population and regional development are closely interrelated. The parameters of development are measured keeping in mind the population of a region.
• The important factors of development are the quantity and quality of population as well as the efficiency of resources used by the population in a region.

Land use and regional development

→ There is a difference in the percentage of land use in developed and underdeveloped regions.

→ Demand for land use changes according to the society’s needs as well as the changes in the socio-economic conditions.

Primary, secondary and tertiary economic activities and regional development

→ Primary, secondary and tertiary economic activities carried out in any region, give an idea about the regional development in that region.

→ Regions are developed if they contribute more in the tertiary sector and depend less on primary activities.

→ The Human Development Index (HDI) is used to access various aspects of development in a region.

Regional imbalance:

→ The balanced regional development policy is considered on economic, social and political grounds.

→ The policy is adopted to reduce inequalities between different regions of a country and also increasing the standard of living to a higher level at a uniform rate.

Causes of regional imbalance in India:

→ There is regional imbalance in India since the level of development is not similar in all sub-regions.

Policies to reduce regional imbalance

→ Identify underdeveloped regions.

→ Identify the reasons behind non-development.

→ Allocate funds to regions which need them in particular sectors or fields.

→ Sector-wise investments to improve conditions of such areas.

→ Funds are given in the form of subsidies and investments in roads, schools, agriculture, irrigation, industries, housing, medical and health facilities, etc.

→ Special care for regions that have been identified as deserts, drought-prone, hilly, and areas dominated by tribal population.

→ Decentralisation of industries to reduce the regional imbalance.

Maharashtra State Board Class 12 Economics Notes Chapter 8 Public Finance in India

Meaning:
Public Finance is a combination of two words – Public and Finance.
Here, public represents government and finance is related to income and expenditure.

Definitions of Public Finance:
According to Hugh Dalton: “Public finance is one of those subjects which are on the borderline between economics and politics. It is concerned with the income and expenditure of public authorities and with the adjustment of one with the other. ”

According to Prof. Findlay Shirras: “Public finance is the study of the principles underlying the spending and raising of funds by public authorities.”

Difference between Public Finance and Private Finance:

(4)

Public Expenditure:
It refers to expenditure incurred by public authority (Central, State and Local bodies).
Public Expenditure is classified as Revenue and Capital Expenditure as well as Developmental and Non-developmental Expenditure.

Reasons for growth in public expenditure:

• Increase in the activities of Government
• Rapid increase in population
• Growing urbanization
• spread
• Spread of democracy
• Inflation
• Industrial Development
• Disaster management

Public Revenue:
It refers to aggregate collection of income with the government through various sources.
Sources of public revenue :
(A) Tax Revenue
(B) Non-Tax Revenue

(A) Tax Revenue: According to Prof. Seligman, “A tax is a compulsory contribution from the person to the Government without reference to special benefits conferred. ”

Characteristic of Tax:

1. Compulsory contribution to the government by every citizen of the country.
2. It helps the government to incur welfare expenses for citizen.
3. Taxpayer does not get any direct benefit by paying tax.
4. It is imposed on income, property, goods and services.

Canons (Principles) of Taxation:
Canons of taxation were propounded by Adam Smith.

→ Canon of Equity or Equality i.e. a person to pay tax as per his ability to pay.

→ Canon of Certainty i.e. a taxpayer should know the amount of tax liability and the way of paying tax.

→ Canon of Convenience i.e. time of levying tax and manner of levying tax should be convenient to taxpayer.

→ Canon of Economy i.e. cost of collecting tax should be minimum.

Types of Taxes:
There are two main types of taxes i.e. Direct Tax and Indirect Tax.

Classification of Direct Tax:

1. Proportionate Tax
2. Progressive Tax
3. Regressive Tax.

Non – tax Revenue:
Revenue received by the government from the source other than tax revenue is called as non-tax revenue.
Sources of Non-tax revenue :

• Fees
• Prices of Public Goods and Services
• Special Assessment
• Fines and Penalties
• Gifts, Grants and Donations
• Special Levies
• Borrowings

G.S.T. – Goods and Services Tax:
It came into effect in India on 1st July, 2017. It is a comprehensive tax base with nationwide coverage of goods and services.
Expected Benefits of G.S.T:

• Creating unified common national market for India.
• Boost foreign investments and “Make in India” campaign.
• Simplify the tax system in the country.
• Improve investment in the country.
• Boost export and manufacturing activity.
• Reducing final price of goods.
• Generating employment and eradicating poverty.

Public Debt:
Generally, government expenditure exceeds government revenue. So, government needs to raise loans, which is called Public Debt.

Types of Public Debt:

→ Internal Public Debt: Borrowings by government within the country i.e. from its citizens, banks, central bank, financial institutions, business houses, etc.

→ External Public Debt: Borrowings by government from outside the country i.e. from foreign governments, foreign banks, international organisations like IMF, World Bank, etc.

Fiscal Policy:
It is a financial policy implemented by the government. It deals with public expenditure, public revenue and public debt.

Financial Administration:
It is concerned with efficient implementation of revenue, expenditure and debt policy of the government. It includes preparation and implementation of government budgets for economic growth.

Government Budget:
It is an important instrument of financial administration to regulate all financial affairs of the state.
Budget is the annual financial statement showing expected receipts and proposed expenditure of the government in a financial year, i.e., from 1st April to 31st March.

Types of Budget:

→ Balanced Budget: When estimated revenue and expenditure of the government are equal, it is said to be balanced budget. Government Receipts = Government Expenditure.

→ Surplus Budget: When estimated government receipts are more than government expenditure, it is said to be surplus budget. Government Receipts > Government Expenditure.

→ Deficit Budget: When government receipts are less than government expenditure, it is said to be deficit budget. Government Receipts < Government Expenditure.

By going through these Maharashtra State Board Class 12 Geography Notes Chapter 6 Tertiary Economic Activities students can recall all the concepts quickly.

Maharashtra State Board Class 12 Geography Notes Chapter 6 Tertiary Economic Activities

→ Natural resources are obtained by primary activities; secondary activities are dependent on products obtained from primary activities. Activities that act as links between primary and secondary are known as tertiary activities.

→ Tertiary activities are mainly service-providing activities. Therefore, it is called the service sector.

→ Buying and selling of goods, transport, and communication, loading and unloading, credit facilities, marketing, import-export, etc., are tertiary activities.

→ The distribution of service activities is dependent on the number of geographical factors like climate, topography, nearness to the sea, or continental location, which affects tertiary activities.

Trade and Commerce

→ Trade refers to the voluntary exchange of goods and services, where two or more parties are involved.

→ Bilateral or multilateral trades are major types of international trade. International trade takes place because of specialisation in production and differences in human resources.

→ International trade takes place only if it is mutually beneficial to trading partners (countries) and when it is a comparative advantage for both.

→ There are various geographical factors that affect trade. These are, differences in natural resources, climate, population factors, culture, economic cost and specialisation.

Transportation

→ Transportation is a service or facility through which passengers, freight and industrial products are carried from one place to another.

→ Transportation is a very important tertiary activity in the development of trade.

→ Means of transportation are essential components of transport systems wherein, each mode has its own requirements and features.

Communication

→ Different means of communication are used to express one’s thoughts and making it reach the other.

→ Communication is being depicted through pictures, symbols, verbal communication using signs, body language, postures, etc.

→ This is the era of information. Therefore, telephones, mobiles, internet, etc., are used to communicate.

→ These means of communication are largely used for regional development. Each country is trying to stay updated with information. Hence, technology in communication has increased manifold.

Other services

→ Tourism is an important tertiary economic activity. The population employed in tourism is increasing.

→ The climate, natural beauty of the region, availability of land and sea adventure sports are major contributors to the country’s GDP.

→ The geographical factors like the site and situation of a place, climate, relief, altitude, biodiversity, accessibility, availability of water plays an important role in the growth of tourism.

→ However, transportation facilities, lodging and boarding facilities, cultural diversity, government policies and political conditions are human factors affecting the development of tourism.

→ Considering tertiary economic activities, the services included in this sector are varied in nature. Therefore, these are categorized into quaternary (fourth) and quinary (fifth) activities.

→ Quaternary activities refer to think, research, and develop ideas whereas quinary activities involve work related to administrative character.

→ The difference between the two types is that the people involved in quinary activities are involved in the highest level of decision-making or policy-making.

By going through these Maharashtra State Board Class 12 Economics Notes Chapter 3B Elasticity of Demand students can recall all the concepts quickly.

Maharashtra State Board Class 12 Economics Notes Chapter 3B Elasticity of Demand

Definition: According to P. A. Samuelson, “Price elasticity is a concept of measuring how much the quantity demanded responds to changing price.”

Elasticity of demand in fact refers to the degree of responsiveness of the quantity demanded of a commodity to a change in the variable on which demand depends.

Types of Elasticity of Demand:

1. Income Elasticity of Demand
2. Cross Elasticity of Demand
3. Price Elasticity of Demand

→ Income Elasticity of Demand: It refers to the degree of responsiveness of a change in quantity demanded to a change in the income only, other factors including price remaining unchanged.
E_y = \(\frac{Percentage change in Quantity Demanded}{Percentage change in Income}\)

Symbolically, it can be written as follows :
E_y = \(\frac{\frac{\Delta \mathbf{Q}}{\mathrm{Q}}}{\frac{\Delta \mathrm{Y}}{\mathrm{Y}}}\) = \(\frac{\Delta \mathrm{Q}}{\mathrm{Q}}\) × \(\frac{\mathrm{Y}}{\Delta \mathrm{Y}} \)

Where,
Q = Original Quantity Demanded
Y = Original Income
ΔQ = Change in Quantity Demanded
Y = Change in income

→ Positive Income Elasticity: Normal goods which includes necessaries, comforts and luxuries, for which demand increases with increase in income. There is direct relationship between income and quantity demanded. Normal goods have positive income elasticity.

→ Negative Income Elasticity: Inferior goods have a negative income elasticity. As income increases the demand for inferior goods fall. There is an inverse relationship between income and quantity demanded of inferior commodity. Inferior goods are substituted by superior goods.

→ Zero Income Elasticity: When change in income does not have any effect on the demand for a
commodity then the income elasticity is zero for e.g. goods like salt, pins, etc.

Cross Elasticity of Demand: Cross Elasticity of Demand refers to the degree of responsiveness of quantity demanded of a commodity X to a given change in the price of commodity Y. X and Y may be a substitute or complementary goods like tea or coffee or car and petrol.

Cross Elasticity = \(\frac{Percentage change in Quantity demanded of commodity ‘X’}{Percentage change in Price of commodity ‘Y’}\).

Symbolically, it can be written as follows:
E_c = \(\begin{gathered}
\frac{\Delta \mathrm{Q} x}{\mathrm{Q} x} \\
\hline \frac{\Delta \mathrm{P} y}{\mathrm{P} y}
\end{gathered}\) = \(\frac{\Delta \mathrm{Q} x}{\mathrm{Q} x}\) × \(\frac{\mathrm{P} y}{\Delta \mathrm{P} y}\)

Qx = Original Quantity demanded of commodity ‘X’
Py = Original Price of commodity ‘Y’
ΔQx = Change in Quantity demanded of commodity ‘X’
ΔPy = Change in Price of commodity ‘Y’

Price Elasticity of Demand: Price Elasticity of Demand refers to the degree of responsiveness of quantity demanded of a commodity to the change in its price, other factors remaining constant.

According to Prof. Alfred Marshall, “Price Elasticity of Demand (Ed) is the ratio of proportionat e
change in quantity demanded ola commodity to a given proportionate change in its price.”

E_d = \(\frac{Percentage change in Quantity demanded}{Percentage change in Price}\)
Ed = \(\begin{gathered}
\frac{\Delta \mathrm{Q}}{\mathrm{Q}} \\
\hline \frac{\Delta \mathrm{P}}{\mathrm{P}}
\end{gathered}\) = \(\frac{\Delta Q}{Q}\) × \(\frac{\mathrm{P}}{\Delta \mathrm{P}}\)

ΔQ = Change in quantity demanded (New quantity – Old quantity demanded)
ΔP = Change in Price (New price – Old price)
P & Q = Original price and original quantity demanded.

(a) Unitary Elastic Demand : (Ed = 1) .
When proportionate or percentage change in quantity demanded is exactly equal to proportionate or percentage change in price, then demand is said to be unitary elastic. For instance a 10% fall in price of a commodity leads to 10% rise in demand of that commodity.

Ed =\(\frac{Percentage change in Quantity demanded}{Percentage change in Price} \)
Ed =\(\frac{10}{10}\) = 1 Slope of the curve is rectangular hyperbola
∴ Ed = 1

(b) Relatively Elastic Demand: (Ed> 1)
When proportionate or percentage change in quantity demanded is more than proportionate or percentage change in price, then demand is said to be relatively elastic demand. For instance a 5% fall in price of a commodity leads to 10% rise in demand of that commodity.
Ed= \(\frac{Percentage change in Quantity demanded}{Percentage change in Price}\)
Ed = \(\frac{10}{5}\) = 2
i.e. Ed> 1
Slope of the curve is flatter.

(c) Relatively Inelastic Demand : (Ed < 1) When proportionate or percentage change in quantity demanded is less than proportionate or percentage change in price, then demand is said to be relatively inelastic demand.

For instance a 10% fall in price of a commodity leads to 5% rise in demand of that commodity. . Ed = \( \frac{Percentage change in Quantity demanded}{Percentage change in Price}\) Ed = \(\frac{5 \%}{10 \%}=\frac{1}{2}\) = 0.5 i.e. e>1
Slope of the curve is steeper slope.

(d) Perfectly Elastic Demand or Infinitely Elastic Demand: (Ed =∞)
When a slight change or no change in the price of a commodity Y brings about infinite change in the demand, then it is said to be perfectly elastic demand. For instance, fall in price by 5% may lead to an infinite rise in demand.

Ed = \( \frac{Percentage change in Quantity demanded}{Percentage change in Price} \)
Ed= \(\frac{\text { Any Number }}{0}\) =∞
e = ∞
Slope of the curve is horizontal slope.

(e) Perfectly Inelastic Demand: (Ed = 0)
When a proportionate or percentage change in price brings no effect on quantity demanded of a commodity, then it is said to be perfectly inelastic demand. For instance price falls by 10% or rise by 10%, demand remains constant.

Ed = \( \frac{Percentage change in Quantity demanded}{Percentage change in rice}\)
Ed = \(\frac{0}{10}\) = 0
e = 0
Slope of the curve is vertical.

By going through these Maharashtra State Board Class 12 History Notes Chapter 10 Cold War students can recall all the concepts quickly.

Maharashtra State Board Class 12 History Notes Chapter 10 Cold War

→ The term was first used by Walter Lippmann, an American political columnist.

→ The struggle between two superpower nations was known as Cold War. In such a war, nations do not use weapons but have a competition to show their power by researching new weapons, technology, the space race, etc.

→  It started after World War – II Whole world was divided into two superpower nations i.e. America and Russia.

→  Russia ruled over Eastern Europe and America, England and France got Western Europe. We can say that Europe was divided into Communist ideology (Russia) and Capitalist and democratic ideology (America).

Progression of Cold War:

→ Europe was divided into two Superpowers namely America and Russia.

→ The Soviets were supporting Communists based on Government ownership and America was supporting Capitalists based on private ownership. Many important events took place like the Sino-Soviet Treaty of Friendship’ and ‘Korean Conflict’.

→ Russian Prime Minister Stalin and American President Eisenhower tried to maintain peaceful co-existence but tension arose at the Cuba incident.

→ Mikhail Gorbachev was the new leader of Russia in 1985. His period was known as the end of the Cold War. His ideology for Russia was restructuring and openness.

→ There was chaos in world politics during the cold war such as the world was divided into two Superpower groups, misunderstanding between nations, the invention of weapons, etc.

→ Few agreements were signed by America and Russia like NATO, SEATO, ANZUS, CENTO, and Warsaw Pact.

NATO:
was signed by 29 European countries, members were Norway, America, Italy, Denmark, Netherland, Portugal, Turkey, Belgium, Canada, Iceland, Germany, Luxemburg, and Spain.

→ According to this treaty attack on any member, country would be treated as an attack on all member countries.

→ All will maintain peace and security.

→ Any problem among members can be solved through discussion.

→ Headquarters of NATO will be in Paris and America had a significant role in decision making in NATO.

→ Against Nato, Russia signed the Warsaw Pact with communist nations in Europe.

ANZUS: Treaty was signed by
A: Australia
NZ: New Zealand
US: America

This is known as three-way defence pact. Main moto to form this treaty was to protect the ‘ countries in Pacific Ocean from communist China and did not want England and France to have any upper hand in the matter of their national security.

SEATO:

→ In September 1954, the United States, France, Great Britain, New Zealand, Australia, Philippines, Thailand and Pakistan formed the Southeast Asia Treaty Organisation or SEATO.

→ SEATO’s main goal was to stop the spread of communism and the organisation did this in various ways.

CENTO:
The Central Treaty Organisation (CENTO), originally known as the Baghdad Pact or the Middle East Treaty Organisation (METO), was a military alliance of the cold war. It was formed in 1955 by Iran, Iraq, Pakistan, Turkey and the United Kingdom and dissolved in 1979.

Sino – Soviet Security Pact:
This treaty was between Russia and China. Russia was ready to provide economic, industrial, and technological aid to China.

Warsaw Pact:
Soviet Russia and seven communist countries from Europe namely Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania signed this treaty to strengthen communist nations and oppose American policies.

Non-Alignment Policy of India:

• India remained neutral and shaped its own peace strategies. This is known as ‘NAM’.
• Pt. Jawaharlal Nehru and few others were the architects of NAM.
• NAM is about adopting foreign policy with peace, supporting other nations’ struggle for independence, not involving in any treaty with superpower nations.

SAARC.

1. An organisation which would work for economic and social development in Asia.
2. Bangladesh, Bhutan, India, Pakistan, Sri Lanka, Maldives and Nepal are members of SAARC.

Commonwealth.

Maharashtra State Board Class 12 History Notes Chapter 7 Decolonisation to Political Integration of India

→ In the last lesson, we have studied various revolts that took place in India against British or East India companies.

→ In this lesson, we are going to study ‘Decolonisation’ which means the process of ending British power and all power transferred to the people of India.

→ As we know India was ruled by many kings and kingdoms, India got its independence on August 15, 1947.

→ But, after independence, the princely states had the right to be free or remain independent.

→ Sardar Vallabhbhai Patel played a very important role to unite India. Let’s study the story of various events.

Decolonization to Political Integration of India.
After Independence India had more than 600 princely states. Meanwhile, many movements were started like Non-co-operation movement. Sardar Vallabhbhai Patel handled the situation with great skill and tact and won the confidence of the rulers of these states and they have merged in India, except Junagadh, Hyderabad and Kashmir.

→  Junagadh: Junagadh’s Nawab of Saurashtra wanted to join Pakistan and people from Junagadh wanted to be a part of India. In February 1948, he escaped from India and joined Pakistan. Junagadh became a part of Independent India.

→  Hyderabad: Hyderabad was under the Nizam and had three languages Telugu, Kannada and Marathi. He imposed many restrictions. To fight with Nizam people established Andhra Parishad in Telangana, Maharashtra Parishad in Marathwada and Karnataka Parishad in Karnataka.

→  Swami Ramanand Tirth formed workers organisation called Hyderabad State Congress against Nizam. Later on, Nizam and Kasim Razvi (Razakar Organisation head) had to surrender against Independent nation, campaign started by India called ‘Operation Polo’. In September 1947, Hyderabad merged with India.

→  Kashmir: Story of Kashmir was different, ruler Hari Singh wanted to be independent, neither wanted to join Pakistan nor India. But Pakistan wanted it in Pakistan. Later on, Pakistan attacked Kashmir, Hari Singh asked Pandit Nehru to help him by signing the act.

→ Soon, Indian army were sent, but some part of Kashmir was captured by Pakistan Army. This matter arose in UNO and soon it was declared ‘International Issue’. The constitution of Jammu and Kashmir was drafted, it became part of India. Jammu and Kashmir got special status by ‘Article 370.’

→  Dadra and Nagar-Haveli:
Dadra and Nagar Haveli was under the dominance of Portuguese and a part of Gujarat, near the river Damanganga. It was assumed that after India got independence, Portuguese also would hand over these regions to India. But it was not like that, they did not do so.

→  Many organisations like United Front of Goans, Azad Gomantak Dal started campaign, Portuguese governor tried to suppress it but they failed and Nagar Haveli was captured by people. Soon the branch of Azad Gomantak Dal also captured Dadra. Azad Mukti Sena and Azad Gomantak Dal captured some more parts of it. Many police and administrative offices were attacked. To come back in normal situation, Governor of India was appointed. In August 1954, Dadra and Nagar Haveli became a part of Nation and in 1961 declared status of Union Territory.

→  Goa: Goa was also under the rule of Portuguese. It was necessary to get freedom from Portuguese. For this already committee was formed in Mumbai. Soon this committee started campaign against Portuguese. Dr. Kunha played an important role, started struggle of weapons against Portuguese. He was arrested when he got shot and injured during attack on police station.

→ ‘Maratha’ newspaper was continuously publishing article to gain support for the movement started by Dr. Kunha. This alarmed Pandit Nehru and soon the army was sent for mission in Goa. Army operation was called ‘Operation Vijay’. In this operation the civilians of Goa helped the army to show the places where landmines were planted. Within 48 hours Portuguese surrendered to Indian Army. In 1961, Goa was free from Portuguese after 461 years.

→  Puducherry: Same as Goa, Puducherry was also in hands of the French. It was a clear message to the French Colony that British and Portuguese had left from here, now it is French’s turn. But it was not easy. Puducherry, Chandranagar, West Bengal and many small states were under the French power. French government was not willing to surrender. People of Puducherry came together.

→ Seeing this serious matter Government of India demanded to return the Indian regions captured by French. In 1948 agreement of negotiations were signed and issues of Puducherry were solved. In 1949-50, positive response came from Chandranagar, here also an act was signed. In 1954, all colonies of French were merged in India. In 1963 Puducherry declared to be a ‘Union Territory.’

→ It was not easy to merge all princely states into independent nation. Under the leadership of Pandit Jawaharlal Nehru and Sardar Vallabhbhai Patel all princely states merged with India and became an integral part of the Indian republic. Thus, the process of political integration of India was completed.
