GENERAL STUDIES

Sources of Energy: Conventional and Nonconventional Sources –

Energy is one of the most important component of economic infrastructure.

It is the basic input required to sustain economic growth. There is direct relation between the level of economic development and per capita energy consumption.

Simply speaking more developed a country, higher is the per capita consumption of energy and vice-versa. India’s per capita consumption of energy is only one eighth of global average. This indicates that our country has low rate of per capita consumption of energy as compared to developed countries.

Two Main Sources of Energy:

The sources of energy are of following types:

 

 

 

 

 

 (A) Conventional Energy Sources:

The energy sources which cannot be compensated, once these are used (after their exploitation) are termed as conventional energy sources.

Some important conventional energy sources are discussed below:

1. Coal:

Coal is a major conventional energy sources. It was formed from the remains of the trees and ferns grew in swamps around 500 millions year ago. The bacterial and chemical decomposition of such plant debris (which remained buried under water or clay) produced an intermediate product known as peat which is mainly cellulose (C₆H₁₀O₅)_n. Due to progressive decomposition by heat and pressure, the cellulose lost moisture H₂ and O_z and got converted in to coal as per the given equation

The average formula of coal is (C_3/H_4/)_n. Out of the 6000 billion tons coal stocks under earth crust, 200 tons have been exploited the present society. The coal reserves are found in the states like Jharkhand, Orissa, West Bengal, M.P. and A.P. Some important coal fields are :Talcher, Raniganj, Jharia, Bokaro, PanchKonkam, Signoulli, Chanda etc.

2. Petroleum and natural gases:

Petroleum is a complex mixture of hydrocarbons, mostly alkanes and cycloalkanes. It occurs below the earth crust entrapped under rocky strata. In its crude form, the viscous black liquid is known as petroleum and a gas in contact with petroleum layer which flows naturally from oil wells is termed as natural gases. The composition of natural gas is a mixture of mainly methane, (95.0%), small amounts of ethane, propane and butane (3.6%) and traces of CO₂ (0.48%) and N₂ (1.92%).

A liquid mixture of propane and butane can be obtained from natural gas or refinery gases at room temperature under a pressure of 3-5 atmosphere. This is stored and distributed in 40-100 litre capacity steel cylinders.

The crude petroleum after being refined and purified, are available as petrol, diesel, kerosene, lubricating oil, plastic etc. for commercial and domestic use. In India, the oil deposits, are found at Ganga-Brahmaputra Valley, Bombay high, plains of Gujarat, Thardesert of Rajasthan and area around Andaman Nicobar islands.

On the world basis, petroleum deposits are found at Saudi Arab, Iraq, Iran, Kuwait, USA, Mexico, Russia etc. As per the current survey, it is found that world petroleum deposits are diminishing at a very faster rate. If preventive steps are not taken, the existing petroleum will be available maximum up to 40 years.

3. Fuel woods:

The rural peoples require fuel wood or fire Wood for their day to day cooking which are obtained from natural forests and plantations. Due to rapid deforestation, the availability of fire wood or fuel wood becomes difficult. This problem can be avoided by massive afforestation (plantation) on degraded forest land, culturable waste land, barren land grazing land etc.

4. Hydropower:

Energy obtainable from water flow or water falling from a higher potential to lower potential, is known is hydro- power. It is a conventional and renewable form of energy which can be transmitted to long distance through cables and wires.

In India, hydroelectric power is generated by a number of multipurpose river valley projects e.g. Hydro-power project Hirakud, BhakraMangal project, Narmada valley project, NagarjunSagar project, SardarSarovar project etc.

5. Nuclear energy:

A small amount of radioactive substance (U²³⁵) can produce a lot of energy through the process of nuclear fission. For example, one ton of uranium can provide energy which is much higher than three million tons of coal or 12 million barrels of oil. In order to obtain nuclear energy, nuclear reactors are required. There are around 300 nuclear reactors all over the world. India has only four nuclear power stations (reactors).

The nuclear energy can be used in production of electrical energy, as a fuel for marine vessel and space crafts and for the generation of heat in chemical processing plants. In India, Uranium deposits are found at different parts of Rajasthan and Singhbum of Jharkhand.

Thorium is recovered from monazite sand found in the state of Kerala. Due to the higher energy releasing tendency of these radioactive substances, these can be used in nuclear reactors to release energy crisis. But the radioactive substances are exhaustible and can be used to develop nuclear weapons of mass destruction. In addition, dumping or radioactive wastes cause serious environmental hazards.

(B) Non conventional energy sources:

The conventional energy sources discussed above are exhaust­ible and in some cases, installation of plants to get energy is highly expensive. In order to meet the energy demand of increased popu­lation, the scientists developed alternate nonconventional natural Resources sources of energy which should be renewable and provide a pol­lution free environment.

Some nonconventional, renewable and inexpensive energy sources are described below:

1. Solar energy:

Solar energy, a primary energy source, is non-polluting and inexhaustible.

There are three methods to harness solar energy:

(i) Converting solar energy directly into electrical energy in solar power stations using photo cells or photovoltaic cells or silicon solar cell.

(ii) Using photosynthetic and biological process for energy trapping. In the process of photosynthesis, green plants absorb solar energy and convert it into chemical energy, stored in the form of carbohydrate.

(iii) Converting solar energy in to thermal energy by suitable devices which may be subsequently converted into mechanical, chemical or electrical energy.

Since solar energy is non-ending and its conversion to some other energy form is nonpolluting, attention should be paid for the maximum utilization of solar energy.

2. Wind energy:

Wind is air in motion. The movement of air takes place due to the convection current set out in the atmosphere which is again due to heating of earth’s surface by solar radiation, rotation of earth etc. The movement of air occurs both horizontally and vertically.

The average annual wind density is 3 kW/m²/day along costal lines of Gujarat, western ghat central parts of India which may show a seasonal variation (i.e., in winter it may go up to 10kW/m²/day).]

Since wind has a tremendous amount of energy, its energy can be converted into mechanical or electrical energy using suitable devices, now days, wind energy s converted in to electrical energy which is subsequently used for pumping water, grinding of corns etc. As per available data dearly 20,000 mW of electricity can be generated from wind. In Puri, wind farms are set up which can generate 550 kW of electricity.

3. Tidal energy:

The energy associated with the tides of the Ocean can be converted in to electrical energy. France constructed the first tidal power plant in 1966. India could take up Ocean thermal energy conversion (OTEC) and by the process it will be capable of generating 50,000 mW of electricity, to meet the power requirements of remote oceanic islands and coastal towns. The Netherlands is famous for windmills. In India, Gujarat and Tamil nadu have windmills. The largest wind farm has been set at Kanyakumari which generates 380 mW of electricity.

4. Geothermal energy:

The geothermal energy may be defined as the heat energy obtainable from hot rocks present inside the earth crust. At the deeper region of earth crust, the solid rock gets melted in to magma, due to very high temperature. The magma layer is pushed up due to some geological changes and get concentrated below the earth crust. The places of hot magma concentration at fairly less depth are known as hot spots.

These hot spots are known as sources of geothermal energy. Now a days, efforts are being made to use this energy for generating power and creating refrigeration etc. There are a quite few number of methods of harnessing geothermal energy. Different sites of geothermal energy generation are Puga (Ladakh), Tattapani (Suraguja, M.P.), Cambay Basin (Alkananda Valley, Uttaranchal).

5. Bio-mass based energy:

The organic matters originated from living organisms (plants and animals) like wood, cattle dung, sewage, agricultural wastes etc. are called as biomass. These substances can be burnt to produce heat energy which can be used in the generation of electricity. Thus, the energy produced from the biomass is known as biomass energy.

There are three forms of biomass:

(i) Biomass in traditional form:

Energy is released by direct burning of biomass (e.g. wood, agricultural residue etc.)

(ii) Biomass in nontraditional form:

The biomass may be converted in to some other form of fuel which can release energy. For example carbohydrate can be converted into methanol or ethanol which may be used as a liquid fuel.

(iii) Biomass for domestic use:

When organic matters like cow dung, agricultural wastes, human excreta etc. subjected to bacterial decomposition in presence of water in absence of air, a mixture of CH₄, C0₂, H₂, H₂S etc. is produced. These gases together is known as biogas. The residue left after the removal of biogas is a good source of manure and biogas is used as a good source of non-polluting fuel.

6. Biogas:

Biogas is an important source of energy to meet energy, requirements of rural area. As per given data, around 22,420-million m³ of gas can be produced from the large amount of cow dungs obtained in rural areas in a year. The gas is generated by the action of bacteria on cow dung in absence of air (oxygen). There are two types of biogas plants namely. Fixed done type and floating gas holder type .

These plants are commonly known as Gobar gas plants because the usual raw material is cow dung (Gobar). The methodology involves in the process is to prepare a slurry of cow dung with water. Sometimes form waters can also be added to the slurry.

The slurry is subjected to bacterial decomposition at 35 .C. There are about 330, 00 biogas plants in India. All India dung production is about 11.30 kg per cattle and 11.60 kg per buffalo with about 67.10 m³ of gas per ton of wet dung.

 

7. Petro plants:

In order to release the pressure on mineral oils (a nonrenewable resource), the scientists have discovered some potential plant species from which liquid hydrocarbons can be extracted. The liquid hydrocarbons present in such plants can be converted in to petroleum.

Such plants are known as petro plants which belong to families Apocynaceae, Ascalepiadaceae, Euphrobiaceae; Convolvulaceae and Spontaceae. Still research is on to increase the biomass of the petro plants and effective method of converting their hydrocarbons in petroleum.

8. Dendrothermal energy (Energy plantation):

Due to rapid deforestation and overgrazing, a number of denuded wastelands are formed. On these wastelands, fast growing trees and shrubs may be planted which will provide fuel wood, charcoal, fodder, etc. Through gasification, these plants can produce a lot of energy-

9. Baggasse-based plants:

Bagggasse is generated as a waste product in sugar mills. This can be utilised to produce electrical energy. As per available data, the sugar mills in India can generate about 2000 mW surplus electricity during crushing season.

10. Energy from urban waste:

Sewage and solid municipal wastes can also generate energy on their suitable treatments.

 

 

Historical context

• The emergence of agricultural Price Policy in India was in the backdrop of food scarcity and price fluctuations provoked by drought, floods and international prices for exports and imports. This policy in general was directed towards ensuring reasonable food prices for consumers by providing food grains through Public Distribution System (PDS) and inducing adoption of the new technology for increasing yield by providing a price support mechanism through Minimum Support Price (MSP) system.
• In recognition of the importance of assuring reasonable produce prices to the farmers, motivating them to adopt improved technology and to promote investment by them in farm enterprises, the Agricultural Prices Commission (renamed as the Commission for Agricultural Costs and Prices in 1985) was established in 1965 for advising the Government on agricultural prices policy on a continuing basis.
• The thrust of the policy in 1965 was to evolve a balanced and integrated structure to meet the overall needs of the economy and with due regard to the interests of the producers and the consumers. The first Commission was headed by Prof M L Dantwala and in its final report the Commission suggested the Minimum Support Prices for Paddy.

 

Minimum Support Price (MSP):- is a form of market intervention by the Government of Indiato insure agricultural producers against any sharp fall in farm prices.

• The minimum support prices are announced by the Government of Indiaat the beginning of the sowing season for certain crops on the basis of the recommendations of the Commission for Agricultural Costs and Prices (CACP). 
• MSP is price fixed by Government of India to protect theproducer – farmers – against excessive fall in price during bumperproduction years.
• The minimum support prices are a guarantee price for their produce from the Government that this will be the minimum price at which their product will fetch.
• If the market price is above,MSP,the farmer can obviously sell it at the marketIn case the market price for the commodity falls below the announced minimum price due to bumper production and glut in the market,government agencies purchase the entire quantity offered by the farmers at the announced minimum price.

  The major objectives are to support the farmers from distress sales and to procure food grains for public distribution.

  As of 2015-16, Minimum support prices are currently announced for 24 commodities,which includes food grains like Wheat,paddy etc and non-food crops like raw cotton,raw jute etc.

• A pilot project under the Direct Payment Deficiency System (DPDS) for paying MSP guarantee for the cotton farmers has been initiated at Hinganghat taluka of Maharashtra in 2015. Under this system, the farmers will directly get the amount which is the difference between the Minimum Support Price (MSP) and the market price, should the market price fall below the MSP. For availing of the benefit, farmers would have to present proof of cotton sold at Agriculture Produce Market Committee yards, plus other papers such as ownership document, yield estimation and other details. If the pilot is successful, the DPDS would be rolled out in all cotton growing regions, as per the present decision. DPDS is essentially a mode of direct benefit transfer to cotton farmers.

  Then there is this concept ofPROCUREMENT PRICE, which is the price at which government procures food grains for buffer stocking and PDS purposes through FCI.

• Consider the situation where,in the wake of an imminent food shortage that may occur, the traders are willing to procure food grains in advance,driving up the market price.

 

• When the market prices are much higher than the MSP,the farmer will obviously be willing to sell it in the market.
• But the government,still, needs to procure food grains on its own to meet its distribution commitments inPDS at subsidised rates(issue price) and to create the buffer stock,necessary to intervene from supply side in case there is food deficiency and high food inflation.
• Therefore the government so as to fulfil these commitments,declares a Procurement price which is > or = to the MSP.

  The major difference between MSP and PP is that while PP is forfood grains only, MSP is for 24 crops which includes both food grains and non-food grains.

 

Method of Calculation

• In formulating the recommendations in respect of the level of minimum support prices and other non-price measures, the CACP takes into account a comprehensive view of the entire structure of the economy of a particular commodity or group of commodities.
• Other Factors include cost of production, changes in input prices, input-output price parity, trends in market prices, demand and supply, inter-crop price parity, effect on industrial cost structure, effect on cost of living, effect on general price level, international price situation, parity between prices paid and prices received by the farmers and effect on issue prices and implications for subsidy.
• The Commission makes use of both micro-level data and aggregates at the level of district, state and the country.

Supply related information – area, yield and production, imports, exports and domestic availability and stocks with the Government/public agencies or industry, cost of processing of agricultural products, cost of marketing – storage, transportation, processing, marketing services, taxes/fees and margins retained by market functionaries; etc. are also factored in.

Report of National Commission for Farmers (NCF) had recommended that MSP should be at least 50% more than the weighted average cost of production. However, this had not been accepted by the Government.
Procurement at MSP

• Farmers are made aware of the procurement operations by way of advertisements like displaying banners, pamphlets, announcement for procurement and specification in print and electronic media.
• Some States have taken steps to pre-register farmers for ensuring procurement from them through a software system.
• Keeping in view the procurement potential areas, procurement centres for MSP operations are opened by Government agencies, both Food Corporation of India (FCI) and State Government, after mutual consultations.

• Procurement centres are opened by respective State Govt. Agencies/ FCI taking into account the production, marketable surplus, convenience of farmers and availability of other logistics / infrastructure such as storage and transportation etc. Large number of temporary purchase centres in addition to the existing mandis and depots/godowns are also established at key points for the convenience of the farmers.
• The Govt. agencies also engage Co-operative Societies and Self Help Group which work as aggregators of produce from farmers and bring the produce to purchase centres being operated in particular locations/areas and increase outreach of MSP operations to small and marginal farmers. These Co-operative Societies are in addition to the direct purchases from farmers.
• Co-operative societies/Self Help Groups are engaged in many States like Bihar, Chhattisgarh, Odisha, Maharashtra, Karnataka, Jharkhand and Rajasthan. Whereas, in some states like Punjab and Haryana, the Government of India has permitted the State Governments to engage locals for procurement of food grains from the farmers on payment of commission. These steps have been taken by Government of India so that Govt. agencies can procure maximum food grains directly from farmers by expanding out- reach of MSP benefit to farmers.

• Food Corporation of India (FCI) is the designated central nodal agency for price support operations for cereals, pulses and oilseeds.

 

FUNCTIONAL CLASSIFICATION OF TOWN AND PROBLEM OF HUMAN SETTLEMENT

The definition of function varies across the disciplines. In political science it refers to duties, in mathematics it means the relationship between two variables and in geography it is synonymous to occupation.

Geographers have classified towns on the basis of their site, situation, size, rank, location and relative elevation. Functional classification of towns attempts to categorize towns and cities according to their economic functions, thereby identifying their roles within urban systems. Most classifications use employment and occupational data. In the functional classification approach, towns are classified on the basis of their dominant function. The functional classification of towns has been illus­trated in the following paras:

1.)Administrative town

The main function of administrative cities and towns is to administer the country/state or a specific territory.It includes not only the capital cities of countries, but all the centres of provinces, states, districts and other administrative divisions of the country.

2.Defensive Towns:

During the medieval period, most of the towns and cities used to be developed on the defensive sites.Forts and garrisons used to be constructed at strategic places. The defensive towns have barracks, cantonments, and training facilities for the armed forces, airfields, and harbours for warships.Visakhapatnam, MHOW and Khadakwasla (India);

In many garrison and defensive towns, there is a clear division of land use between the civil and military authorities, so that the military installa­tions are often at a little distance from the town or are grouped together in one part of the town. This is necessary to maintain security, though often many town people are employed by the military.

3.Cultural Centres:

There are numerous towns and cities in the world, almost in each of the countries, which perform cultural functions.The cities of Oxford and Cambridge in England are the most suitable examples of educational towns. In these towns, one may find colleges, libraries, hostels, churches, playgrounds, parks and shopping centres. The environmental pollution in these towns is almost insignificant.

4.) Collection Centres:

The mining towns, fishing ports and lumbering centres fall under the category of collection centres/towns. There are numerous metallic, non-metallics, precious stones and energy resources which are obtained from mines.The towns which serve these mines may be small settlements serving a particular mine such as Zawar near Udaipur (Rajasthan), Bjiladela (Madhya Pradesh) and Digboi (Assam).They may be large in size such as Raniganj, Hazaribagh (Bihar), Ipoh in the tin rich Kinta valley of Malaysia, or Kuwait and Abadan in the oil producing regions of Kuwait and Tehran, respectively.Such towns may have some industries related to the mineral mines, such as smelters and refineries. The shops in such towns sell mining equipments and special clothes needed for miners.

5.) Production Centres:

Urban places, town and cities in which some kind of manufacturing industry is the major function is known as a production centre. The size and appearance of the town are affected by the type of industry located there.

• For example, Jamshedpur, Rourkela, Bhilai, Durgapur, Dhanbad and Bhadravati in India, Pittsburgh in USA, Magnitogorsk in Russia and Birmingham in UK are dominated by large steel plants. Such iron and steel producing towns are generally located near the coal fields.
• For the manufacturing towns, as collecting centres, transportation is very important for the transport of raw materials and the finished goods. These days such towns are generally set up on lines of communication.

In manufacturing towns, there is a segregation of houses and estab­lishments; the officer’s quarters may be grouped at one place and that of the labourers at the other.

6.) Towns of Diversified Functions:

As stated at the outset, towns are classified according to their major functions. So, all those towns (such as Mumbai, Kolkata, Chennai, etc.) can be put into a definite category in which a large number of activities are conducted. Such towns are referred as diversified in functions.

Over space and time, the functions of towns change. For example, defensive sites often become restrictive when the town expands.Thus, many towns have restricted centres which were once confined within the town walls and more extensive suburbs which grew up outside the walls or after the walls were demolished.

Shahjahanabad (old Delhi), Padova (Italy), Lahore and Rawalpindi (Pakistan), Baghdad (Iraq) and Baku (Azerbaijan) are some of the examples of such towns.

7.)Residential Towns:

In some towns, the chief function is simply to house a concentration of population. In such areas, most of the land is devoted to houses, parks and hospitals. These towns are very- well-connected with the major cities, which enables the commuters to get to work each day.

8.  Resorts:

The urban places which cater to the recreation needs of people are known as resorts or recreation towns.These urban places may be based on health-giving water (hot springs), seaside recreation, mountain climbing, cultural attractions, historical monuments, sports facilities, national parks and attractive scenery.Resorts and recreational towns have many hotels to accommodate visitors, and also provide sporting facilities such as golf courses, swimming pools, trekking and skiing. Moreover, they have numerous entertainment facilities, such as theatres, cinemas, and night clubs and children parks.

9. Transfer and Distribution Centres:

The main functions performed at transfer centres are the trade, commerce and services. Towns which are concerned with the transfer and distribution of goods, however, have trade as their major function.

They include several types of towns. For example, market towns, sea ports and financial towns.Market towns are characterized by markets, a wide range of shops, stores, warehouses, godowns, cold storages and wholesale .markets.Market towns also have banks, insurance companies and other financial organizations. Kanpur, Ahmedabad, Vadodara, Indore, Bhopal, Patna, Lucknow, Ludhiana and Hapur in India, Norwich in England, Alexandria in Egypt, and Kumasi in Ghana are some of the examples of such towns.

 

Problem of Human settlement:

Some of the major problems of urbanisation in India are

1. Urban Sprawl

Urban sprawl or real expansion of the cities, both in population and geographical area, of rapidly growing cities is the root cause of urban problems. In most cities the economic base is incapable of dealing with the problems created by their excessive size

2. Overcrowding

Overcrowding is a situation in which too many people live in too little space. Overcrowding is a logical consequence of over-population in urban areas. It is naturally expected that cities having a large size of population squeezed in a small space must suffer from overcrowding. This is well exhibited by almost all the big cities of India.

 

3.Slums and Squatter Settlements:

The natural sequel of unchecked, unplanned and haphazard growth of urban areas is the growth and spread of slums and squatter settlements which present a striking feature in the ecological structure of Indian cities, especially of metropolitan centres.

 

4.)Overcrowding

Overcrowding leads to a chronic problem of shortage of houses in urban areas. This problem is specifically more acute in those urban areas where there is large influx of unemployed or underemployed immigrants who have no place to live in when they enter cities/towns from the surrounding areas.

5.)Seweage problem

Urban areas in India are almost invariably plagued with insufficient and inefficient sewage facilities. Not a single city in India is fully sewered. Resource crunch faced by the municipalities and unauthorised growth of the cities are two major causes of this pathetic state of affairs.

 

 

 

 

 

 

 

 

Conventional and Non Conventional Sources of Energy

Main Sources of Energy:

The sources of energy are of following types:

1. Conventional Sources of Energy:

These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power.

(a) Coal and Lignite:

Coal is the major source of energy. Coal deposits in India are 148790 million tonnes. Total lignite reserves found at Neyveli are 3300 million tonnes. In 1950-51, annual production of coal was 32 million tonnes. In 2005-06, annual production of coal was 343 million tonnes.

Lignite production was 20.44 million tonnes in 2005-06. According to an estimate, coal reserves in India would last about 130 years. India is now the fourth largest coal producing country in the world. Coal deposits are mainly found in Orissa, Bihar, Bengal and Madhya Pradesh. It provides employment to 7 lakh workers.

(b) Oil and Natural Gas:

In India it is found in upper Assam, Mumbai High and in Gujarat. The resources of oil are small in India.

In 1950-51, the total production of oil in India was 0.3 million tonnes. It increased to 32.4 million tonnes in 2000-01. Despite tremendous increase in oil production.India still imports 70% of has oil requirements from abroad. In 1951, there was only one oil refinery in Assam.

After independence 13 such refineries were set up in public sector and their refining capacity was 604 lakh tonnes. After implementation of economic reforms, private refineries are also engaged in oil refining. As per current rate of consumption, oil reserves in India may last about 20 to 25 years.

Electricity

There are three main sources of power generation:

1. Thermal Power
2. Hydro-electric power
3. Nuclear Power
4. Thermal Power:

It is generated in India at various power stations with the help of coal and oil. It has been a major source of electric power. In 2004-05, its share in total installed capacity was 70 percent.

2. Hydro electric Power:

It is produced by constructing dams over overflowing rivers. For example BhakraNangal Project, Damodor Valley Project and Hirakund Project etc. In 1950-51, installed capacity of hydro-electricity was 587.4 MW and in 2004-05, it was 19600 MW.

3. Nuclear Power:

India has also developed nuclear power. Nuclear Power plants use uranium as fuel. This fuel is cheaper than coal. India has nuclear power plants at Tarapur, Kota (Rajasthan) Kalapakam (Chennai) Naroura (UP). Its supply accounts for only 3 percent of the total installed capacity.

POWER FROM NON CONVENTIONAL ENERGY

India is one of the fastest growing countries in terms of energy consumption. Currently, it is the fifth largest consumer of energy in the world, and will be the third largest by 2030. At the same time; the country is heavily dependent on fossil sources of energy for most of its demand. This has necessitated the country to start aggressively pursuing alternative energy sources – solar, wind, biofuels, small hydro and more.

1. Wind Energy

India‘s wind power potential has been assessed at 48500 MW. The current technical potential is estimated at about 13 000 MW, assuming 20% grid penetration, which would increase with the augmentation of grid capacity in potential states. The state-wise gross and technical potentials are given below India is implementing the world’s largest wind resource assessment program comprising wind monitoring, wind mapping and complex terrain projects.

1. Hydro Energy

Hydro power is the largest renewable energy resource being used for the generation of electricity. The 50,000 MW hydro initiatives have been already launched and are being vigorously pursued with DPRs for projects of 33,000 MW capacity already under preparation. Harnessing hydro potential speedily will also facilitate economic development of States, particularly North-Eastern States, Sikkim, Uttaranchal, Himachal Pradesh and J&K, since a large proportion of our hydro power potential islocated in these States. In India, hydro power projects with a station capacity of up to 25 megawatt (MW) each fall under the category of small hydro power (SHP).

1. Solar Energy

India is a solar rich country. India is a country near the equator – which means that given its geographical location, it is subject to a large amount of solar radiation throughout the year. India is also, according to area, the 7th largest country in the world.

The average solar radiation received by most parts of India range from about 4 to 7 kilowatt hours per meter square per day, with about 250-300 sunny days in a year. As can be seen from the solar radiation map above, the highest annual solar radiation is received by Rajasthan (desert area) and the lowest by the North eastern states of India.

1. Biomass energy

Globally, India is in the fourth position in generating power through biomass and with a huge potential, is poised to become a world leader in the utilization of biomass. Biomass power projects with an aggregate capacity of 773.3 MW through over 100 projects have been installed in the country. For the last 15 years, biomass power has become an industry attracting annual investment of over Rs. 1,000 billion, generating more than 09 billion unit of electricity per year. More than 540 million tons of crop and plantation residues are produced every year in India and a large portion is either wasted, or used inefficiently.

69. E) Energy from Wastes: The rising piles of garbage in urban areas caused by rapid urbanization and industrialization throughout India represent another source of nonconventional energy. An estimated 50 million tones of solid waste and approximately 6,000 million cubic meters of liquid waste are generated annually in the urban areas of India. Good potential exists for generating approximately 2,600 MW of power from urban and municipal wastes and approximately 1,300 MW from industrial wastes in India. A total of 48 projects with aggregate capacity of about 69.62 MWeq have been installed in the country thereby utilising only 1.8% of the potential that exists.
70. F) Biofuels: The GOI recently mandated the blending of 10 percent fuel ethanol in 90 percent gasoline. This mandate as created an approximately 3.6 billionliter demand for fuel ethanol in blend mandate to the entire country. This significant demand growth creates a tremendous manufacturing opportunity for the fuel ethanol industry seeking to expand its investments internationally

 

 

 

 

Nuclear policy of india

• Important points of india’s nuclear policy are as follows:
• Building and maintaining a credible minimum deterrent.
• nuclear weapons will only be used in retaliation against a nuclear attack on Indian Territory or on Indian forces elsewhere.
• Nuclear retaliation to a first strike will be massive and designed to inflict unacceptable damage.
• Nuclear retaliatory attack can be authorized by a certain political leadership only through NCA ( nuclear command authority) .
• No-use of nuclear weapons against non-nuclear weapon state.
• In the event of a major attack against India or Indian forces anywhere by biological or chemical weapons. India will retain the option of retaliating with nuclear weapons.
• Continuance of strict control on export of nuclear and missile related materials and technology, participation in the fissile material cut off treaty negotiations and continued observance of the moratorium on nuclear tests.
• Continued commitment to the goal of a nuclear-free world through global verifiable and no discriminatory nuclear disarmament.

 

India’s “minimum credible nuclear deterrence” doctrine and “no first use” policy are based on the concept of deterrence by denial, rather than deterrence by punishment. Should deterrence ever break down, India will have to pay an enormous price for a nuclear first strike by an adversary before launching massive punitive retaliation. Nuclear doctrine has to be ultimately tested in the crucible of operational reality. Across the entire spectrum of conventional conflict, the first use of nuclear weapons by India does not make sound strategic sense. The real distinguishing feature of India’s nuclear doctrine is that it is anchored in India’s continued commitment to global, verifiable and non-discriminating nuclear disarmament.

The concept of deterrence by denial, rather than deterrence by punishment, is central to Indian strategic thinking. However, by voluntarily renouncing its sovereign right of the first use of nuclear weapons to defeat nuclear threats and to prevent nuclear blackmail, India has made an immense strategic sacrifice and imposed a heavy burden upon itself. The government and key decision-makers recognise that should deterrence ever break down, India will have to pay an enormous price for a nuclear first strike by an adversary before retaliating in kind. Hundreds of thousands of Indian lives will be lost and more than one city may be turned into rubble. Hence, India’s no first use doctrine demands a robust, infallible and potentially insuperable nuclear deterrent capability to ensure that India never has to suffer a nuclear strike.

The government also affirmed that India’s nuclear threat perceptions were not country specific. On December 15, 1998, Prime Minister Vajpayee spelt out the principal elements of India’s nuclear policy in a statement in Parliament. India’s resolve to preserve its nuclear independence, minimum nuclear deterrence, no first use, non-use of nuclear weapons against non-nuclear powers, and a firm commitment to the elimination of nuclear weapons. The Prime Minister also reiterated India’s willingness to sign the CTBT and re-stated India’s readiness to work towards the successful conclusion of the Fissile Materials Cut-off Treaty (FMCT). At the Non-Aligned Summit in Durban in 1998, the Movement accepted India’s proposal for an international conference to arrive at an agreement on a phased programme for the complete elimination of all nuclear weapons. At the Millennium Summit of the United Nations in September 2000, the Indian Prime Minister asserted that India’s policy is based on “responsibility and restraint” and that India would continue to press for universal, verifiable nuclear disarmament with undiminished commitment, even while safeguarding “our strategic space and autonomy in decision-making. International peace cannot be divorced from the need for equal and legitimate security for all.

New trends in india’s nuclear policy

More than a decade since the nuclear doctrine was unveiled by the government, several organizations and individuals have commented on it. Some of them have been critical of the no-first-use doctrine. Experts says no first use is not the least credible, because it requires India to first absorb a nuclear attack before responding to enemy’s attack.

In 2011, BJP leader Jaswant Singh had asked for abandonment of the no first use policy but the UPA government decided to maintain status quo. Former prime minister Manmohan Singh, while speaking at the Institute for Defence Studies and Analyses, New Delhi, on April 2, 2014, called for a global “no-first-use” norm. He said, “States possessing nuclear weapons must quickly move to the establishment of a global no-first-use norm. This was followed by the Bharatiya Janata Party (BJP) promising in its election manifesto to “study in detail India’s nuclear doctrine, and revise and update it, to make it relevant to challenges of current times…” and to “maintain a credible minimum deterrent that is in tune with changing geostrategic realities.

Criticism of the nuclear doctrine has mainly been centered on a few key issues: No first use may result in unacceptably high initial casualties and damage to Indian population, cities, and infrastructure, massive retaliation is not credible, especially against a tactical nuclear strike on Indian forces on the adversary’s own territory; nuclear retaliation for chemical or biological attack would be illogical, especially as the attack may be by nonstate actors; and it would be difficult to determine what constitutes a “major” chemical or biological strike.

Most recently, Lt. Gen. B.S. Nagal (Ret.), former commander in chief, Strategic Forces Command, and later head of the Strategic Planning Staff at the National Security Council Secretariat, has questioned the efficacy of the NFU doctrine. According to him, “It is time to review our policy of no first use. The choices are ambiguity or first use.” He gives six main reasons for seeking a change: no first use implies acceptance of large-scale destruction in a first strike, the Indian public is not in sync with the government’s no first use policy and the nation is not psychologically prepared, it would be morally wrong, the leadership has no right to place the population in peril. No first use allows the adversary’s nuclear forces to escape punishment as retaliatory strikes will have to be counter value in nature, an elaborate and costly ballistic missile defense system would be required to defend against a first strike; and escalation control is not possible once nuclear exchanges begin.

Recently india’s Defence minister Manohar parrikar questioned no first use policy . Speaking in New Delhi at the launch of Brigadier (retd) Gurmeet Kanwal’s book The New Arthashastra, Parrikar said: “Why a lot of people say that India has No First Use policy. Why should I bind myself . I should say I am a responsible nuclear power and I will not use it irresponsibly. This is my thinking. However later he clarified this was his individual thinking.

There has again been speculation recently about India’s nuclear doctrine and the value of its no first-use-posture. The reason for the kerfuffle this time are a couple of sentences in former national security advisor Shivshankar Menon’s book, Choices: Inside the Making of Indian Foreign Policy. Menon writes “There is a potential grey area as to when India would use nuclear weapons first against another NWS (nuclear weapons state). Circumstances are conceivable in which India might find it useful to strike first, for instance, against an NWS that had declared it would certainly use its weapons, and if India were certain that adversary’s launch was imminent.

​​The core principles of the Indian nuclear policy have remained unchanged, as has its commitment to a world free from nuclear weapons. Gradually, India has been integrating itself with the non-proliferation regime. Meanwhile, India has joined a number of non-proliferation mechanisms of which it was skeptical before. India is now formally the 35^th member of the Missile Technology Control Regime (MTCR) — an association of countries that share the goals of non-proliferation of delivery systems for nuclear weapons. India is also actively seeking membership of the Nuclear Suppliers Group (NSG). The twenty first century is watching remarkable changes in India’s nuclear policy but for now core of India’s nuclear policy is still the same.

NPT ( NON-PROLIFERATION TREATY)

The NPT is a landmark international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament and general and complete disarmament. The Treaty represents the only binding commitment in a multilateral treaty to the goal of disarmament by the nuclear-weapon States. Opened for signature in 1968, the Treaty entered into force in 1970. On 11 May 1995, the Treaty was extended indefinitely.  A total of 191 States have joined the Treaty, including the five nuclear-weapon States. More countries have ratified the NPT than any other arms limitation and disarmament agreement, a testament to the Treaty’s significance.

Silent provisions of non-proliferation treaty are as follows:

Each nuclear weapon state party to this treaty undertakes not to transfer to any recipient whatsoever, nuclear weapons or other nuclear explosive devices or control over such weapons or explosive devices directly or indirectly; and not in any way to assist, encourage or induce any non-nuclear weapon state to manufacture or otherwise acquire nuclear weapons or other nuclear explosive devices.

Each non-nuclear weapon state party to this treaty undertakes not to receive as transfer from any power whatsoever of nuclear weapons or other nuclear explosive devices or of control over such weapons, explosives, directly or indirectly; not to manufacture or otherwise acquire nuclear weapons or other nuclear explosive devices; and not to seek or receive any assistance in the manufacture of nuclear weapons or other nuclear explosive devices.

All the Parties to the Treaty undertake to facilitate, and have the right to participate in, the fullest possible exchange of equipment, materials and scientific and technological information for the peaceful uses of nuclear energy. Parties to the Treaty in a position to do so shall also co-operate in contributing alone or together with other States or international organizations to the further development of the applications of nuclear energy for peaceful purposes, especially in the territories of non-nuclear-weapon States Party to the Treaty, with due consideration for the needs of the developing areas of the world.

This treaty shall enter into force after its ratification by all nuclear-weapons states signatory to this treaty and by other states signatory to this treaty, after the deposit of their instrument of ratification. For the purpose of this treaty, a nuclear weapons state is one which has manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1st January, 1967.

Each party shall, in exercising its national sovereignty, have the right to withdraw from the treaty if it decided that extra-ordinary events, related to the subject-matter of this treaty, have jeopardized the supreme interests of its country. It shall give notice of such withdrawal to all other parties to the treaty and the United Nations Security Council three months in advance. Such a notice shall include a statement of the extraordinary events it regards as having jeopardized its supreme interests.

India and criticism of NPT

• India thinks NPT is discriminatory. There are two types of members in the NPT – Nuclear Weapons State and Non-Nuclear Weapons State. Only five countries (including China) who had fired a nuclear device before 1970 were given the status of Nuclear Weapons State. Any other nation who wished to sign the NPT, had to do so as a Non-Nuclear Weapons State. India exploded its first nuclear device in 1974 – this implies that the only option by which India could sign the NPT is being a Non-Nuclear Weapons State.
• India needs a minimum nuclear deterrant. If India signs the NPT as a Non-Nuclear Weapons State, India cannot even keep a minimal nuclear deterrant. In the light of the wars waged with neighbours China and Pakistan, this option seems suicidal, given China and Pakistan themselves have nuclear weapons. Therefore even popular political support, across the political spectrum, has been towards nuclear weapons program, rather than signing the NPT.
• NPT unduly tried to legitimize the power gap between nuclear and non-clear nations.
• It did not provide for either disarmament or arms control in international relations.
• It failed to check the N-programmes of France and China which, in violation of the Moscow Partial Test Ban Treaty, continued the policy of conducting nuclear tests.

On the basis of these arguments, critics asserted that NPT failed to solve the problem of nuclear weapons in international relations. It failed to provide any scheme or plan for nuclear disarmament or arms control. Its first review was done in 1975, the second in 1980 and the third in October 1985, but these three reviews failed to secure or improve the realization of the provisions of this treaty

India’s former External Affairs Minister Pranab Mukherjee said during a visit to Tokyo in 2007: “If India did not sign the NPT, it is not because of its lack of commitment for non-proliferation, but because we consider NPT as a flawed treaty and it did not recognize the need for universal, non-discriminatory verification and treatment.”

Comprehensive nuclear test ban treaty ( CTBT )

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is the Treaty banning all nuclear explosions – everywhere, by everyone. The Treaty was negotiated at the Conference on Disarmament in Geneva and adopted by the United Nations General Assembly.

The Treaty was adopted by the United Nations General Assembly on 10 September 1996. It opened for signature in New York on 24 September 1996, when it was signed by 71 States, including five of the eight then nuclear-capable states. As of October 2016, 166 states have ratified the CTBT and another 17 states have signed but not ratified it.

The treaty will enter into force 180 days after the 44 states listed in Annex 2 of the treaty have ratified it. These “Annex 2 states” are states that participated in the CTBT’s negotiations between 1994 and 1996 and possessed nuclear power reactors or research reactors at that time. As of 2016, eight Annex 2 states have not ratified the treaty: China, Egypt, Iran, Israel and the United States have signed but not ratified the Treaty; India, North Korea and Pakistan have not signed it.

Silent features of CTBT are as follows:

• The Treaty banned every kind of nuclear weapons test or nuclear explosion.
• An international monitoring system was to be set up for checking violations of CTBT.
• Any underground, atmospheric or underwater explosions more powerful than the equivalent of 1,000 tones of conventional explosive was to be detected by a network of 20 stations.
• Further, based on information collected by the international monitoring system or through surveillance by individual countries (but not through spying activities), any country could request an inspection to see whether an explosion had been carried out or not. A request for an inspection was to require 30 votes in the 51-member Executive Council.

India and criticism of CTBT

In May 1998, India and Pakistan conducted a series of nuclear tests. Not only did this jolt the nonproliferation regime, the tests also broke a global moratorium on nuclear testing that had been in existence since July 1996, a moratorium that had been reinforced by the adoption of the Comprehensive Test Ban Treaty (CTBT) in September 1996. For India, the tests were the culmination of a major turnaround in policy. When the negotiations that led to the CTBT commenced in 1994, India in fact displayed enthusiasm for the treaty. However, by the time negotiations concluded in 1996, India had emerged as the treaty’s strongest opponent. On June 20, 1996, India declared its unwillingness to sign the CTBT, stating that because the treaty “is not conceived as a measure towards universal nuclear disarmament. India cannot subscribe to it in its present form.”2 On September 10, 1996, when the CTBT was adopted at the United Nations, India stated that it would “never sign this unequal Treaty, not now, nor later.

India’s interest in a test ban was first outlined in an April 1954 speech to the Indian Parliament, when Prime Minister Jawaharlal Nehru called for an end to nuclear testing as a stepping stone towards nuclear disarmament. Nehru stated that, “Pending progress towards some solution, full or partial, in respect of the prohibition and elimination of these weapons of mass destruction, the Government of India would consider, some sort of what may be called a standstill agreement” on ending nuclear testing. In the following decades, New Delhi remained enthusiastic about disarmament. But it simultaneously opposed the NPT and CTBT for ideological and security reasons. India’s rationale behind its stand are as follows:

India felt that the CTBT was inadequate in terms of securing disarmament commitments from the nuclear weapon states under declared deadlines. It saw this as a discriminatory replication of the imbalance inherent in the Nuclear Non-Proliferation Treaty (NPT) regime, in which nuclear weapon states are weakly obligated to disarm and non-nuclear weapon states are strongly obligated to remain non-nuclear. The lack of commitments by the nuclear weapon states to eliminate their nuclear weapons under a declared time frame also compelled India to oppose Article XIV of the NPT, which stipulates the CTBT’s entry into force after 44 “Annex 2″ countries sign and ratify it.

India’s argument is that his  strategic program needs to be safeguarded until a credible disarmament process begins. On a sublime note, some in India will contend that the CTBT remains improvident until the nuclear weapon states commit to a time-bound disarmament framework. Yet to get the ball rolling on eliminating nuclear weapons, India passes the responsibility to the permanent five members of the U.N. Security Council (the five nuclear weapon states recognized under the NPT). India cannot accept any restraints on its capability if other countries remain unwilling to accept the obligation to eliminate their nuclear weapons.”

Settlement can be defined as any form of human habitation which ranges from a single dwelling to large city. The word settlement has another connotation as well as this is a process of opening up and settling of a previously uninhabited area by the people. In geography this process is also known as occupancy.

Settlements can broadly be divided into two types – rural and urban. Before discussing about meaning and types of rural and urban settlement in India, we should know some basic differences between rural and urban areas in general. (i) The major difference between rural and urban areas is the function. Rural areas have predominantly primary activities, whereas urban areas have domination of secondary and tertiary activities. (ii) Generally the rural areas have low density of population than urban.

Types of Rural Settlements:

Geographers have suggested various schemes of classification. If we group settlements found all over the country, these can broadly be grouped under four categories:

1. Compact/clustered/nucleated settlement
2. Semi-compact/Semi-clustered/fragmented settlement
3. Hemleted settlement
4. Dispersed settlement

 

Compact Settlements:

• As the name suggests, these settlements have closely built up area. Therefore in such settlements all the dwellings are concentrated in one central sites and these inhabited area is distinct and separated from the farms and pastures.
• Maximum settlements of our country comes under this category. They are spread over almost every part of the country.
• These settlements are distributed over the entire northern Indo-Ganga plain (from Punjab in the north-west to West Bengal in the east), Orissa coast, basins of Mahanadi in Chhattisgarh, coastal areas of Andhra Pradesh, cauvery delta of Tamil Nadu, Maidaus of Karnataka, lower Assam and Tripura, in the valleys of Siwaliks etc.
• Sometimes people live in compact settlement for security or defence purpose. The greatest example of this type is in Bundelkhand region of Madhya Pradesh and Uttar Pradesh.
• In Rajasthan also people live in compact settlement because of the scarce availability of cultivable land and water body. Therefore, they want to make maximum use of available natural resources.

Semi compact Settlement:

As the name suggests, the dwellings or houses are not well-knitted. Such settlements are characterized by a small but compact nuclears around which hamlets are dispersed.

• It covers more area than the compact settlements.
• These settlements are found both in plains and plateaus depending upon the environmental conditions prevailing in that area.
• Such settlements are situated along streams in Manipur Mandla and Balaghat districts of Madhya Pradesh, and Rajgarh district of Chhattisgarh. Different tribal groups inhabit such settlements in the Chhota Nagpur region. In Nagaland, such settlements may be in the form of blushing villages.

Hamleted Settlements:

These type of settlements, are fragmented into several small units. The main settlement does not have much influence on the other units. Very often the original site is not easily distinguishable and these hamlets are often spread over the area with intervening fields. This segregation is often influenced by social and ethnic factors. The hamlets are locally named as faliya, para, dhana, dhani, nanglay etc. These settlements are generally found in West Bengal, eastern Uttar Pradesh, Madhya Pradesh and coastal plains. Geographically it covers lower Ganga plain, lower valleys of the Himalayas and central plateau or upland region of the country.

 Dispersed Settlements:

This is also known as isolated settlements. Here the settlement is characterized by units of small size which may consist of a single house to a small group of houses. It varies from two to seven huts. Therefore, in this type, hamlets are scattered over a vast area and does not have any specific pattern. Such type of settlements are found in tribal areas of central part of India covering Chhota Nagpur plateau, Madhya Pradesh, Rajasthan, etc. Such patterns are also common in the hills of north Bengal, Jammu & Kashmir, Tamil Nadu and Kerala.

 

There are three factors that influence the type of settlements in India. These factors are (i) Physical (ii) Ethnic or cultural and (iii) Historical or defence. Let us discuss these factors one by one.

Physical Factors:

These include relief, altitude, soil capability, climate, drainage, ground water level, etc. These factors influence the type and spacing of dwelling or instance, in dry regions of Rajasthan, water is a crucial factor and, therefore, houses are situated along a pond or well which guides the compactness of the settlement.

Ethnic and Cultural Factors:

These include aspects like caste, community, ethnicity and religion. In India it is commonly found that the main land owning caste resides at the centre of the village and the other service providing castes on the periphery. This leads to social segregation and fragmentation of a settlement into several units

Historical or Defence Factors:

In the past, mostly border areas of northwestern plains were conquered or attacked frequently by outsiders. For a long time, apart from attack from outsiders, there had been continuous fight between princely states and kingdom within the country therefore, security concerns favoured the evolution of nucleated settlements.

 

Type of urban settlement:

Like rural settlements, urban settlements are classified on various bases. However, classification based on size and function are most common. Let us discuss them one by one

Classification based on Population Size

According to population size, census of India classifies urban centres into six classes. Classwise urban settlements and their population

Class                              Population

Class I                            1,00,000 and above

Class II                          50,000 – 99,999

Class III                          20,000 – 49,999

Class IV                          10,000 – 19,999

Class V                            5,000 – 9,999

Class VI                          less than 5,000

 

There is another classification of urban settlements. The classification is as follows:

Town                                   Places which have less than one lakh population

City                                     Urban centres having population between one lakh to one million.

Metropolitan Cities          Cities having population in between one million to five million

Mega cities                         Cities having more than 5 million population

 

One of the basic tenets of our foreign policy has been non-alignment. As an element of foreign policy non-alignment m e a n s i n d e p e n d e n t o f b l o c s , peaceful coexistence, global peace, disarmament, struggle against all manifestations of injustices like imperialism, colonialism, apartheid etc.

After India’s adoption of non-alignment as the core element of its foreign policy, it also became a model for other newly independent countries. Most of them adopted it as an instrument for independence in international relations. Soon non-alignment, in addition to a significant perspective of foreign policy, became a movement of solidarity and cooperation among the newly liberated countries of Asia, Africa and Latin America. Non-Aligned Movement (NAM) was thus founded as a solidarity movement for giving voice to Third World Countries.

Its essential purpose was to maintain equidistance in cold War rivalries and advocate principles for the promotion of world peace and cooperation. In due course of time, NAM became the largest membership movement as also the largest peace movement in the history of humanity. In both, in its founding and later consolidation and development, India played a significant role. In fact, in many ways India has been considered as a non-formal leader of the NAM.

ORIGIN OF NAM AND INDIA’S ROLE

Though as a formal organised movement NAM started with the holding of the Belgrade Summit of Non- Aligned countries in 1961, its seeds were sown by India, particularly by Jawaharlal Nehru even before attainment of India’s independence. It is quite clear that Nehru was articulating the ideas of decolonisation, national independence, non-bloc politics, peaceful coexistence, eradication of racialism and the need for the developing countries to play an active role in international affairs. It was at the initiative of Jawaharlal Nehru that India became the venue of the first forum of the liberated nations, when representatives of 28 countries met in New Delhi in March 1947 (before formal declaration of independence of India) at the Conference on Regional Cooperation among the Asian Countries known as Asian Relations Conference.

The Asian Relation Conference thus can truly be called the foundation stone for NAM.

BANDUNG CONFERENCE

Along with Nehru some other leaders in the world were also projecting these perceptions of newly independent countries. President Josip Broz Tito of Yugoslavia, President Gamel Abdul Nasser of Egypt (then called United Arab Republic), President Kwarne Nkrumah of Ghana and President Ahmed Soekarno of Indonesia were prominent among these. Together with Nehru they evolved a coherent outlook and position on Non-Alignment.

These leaders were largely instrumental in channelling the emerging changes towards the liberation of the people of the world and towards evolving a new vision of the world order. They rejected outright the notion that East- West relations alone constituted international affairs and asserted their own role in shaping these affairs. On the initiative of these leaders the conference of Afro-Asian Nations was held in Bandung (Indonesia) in April 1955.

The participants from 23 Asian and 6 African States represented mainly the people of young States which had been setup as a result of the new balance of forces of democracy and freedom on the one hand and of colonialism and oppression on the others. The states participating in the conference did not belong to any military or political blocs, arid they had taken clear and definite positions the problems facing mankind. Despite their different perspectives, the countries represented at the Bandung Conference arrived at a common position in the larger interest of world peace. One of the most important achievements of the Bandung Conference was the Declaration on World Peace and Cooperation. This declaration embodied the principles of Panchsheel which were first stated in the Preamble to the agreement between India and China in April 1954.

INDIA’S PIVOTAL ROLE AT NAM

It is quite clear that in the founding of NAM India not only played an active role as one of the founders but in many ways it was the initiator of the Movement. As we have already seen non-alignment as a concept of global politics, as a foreign policy premise and as a perspective of maximising national interest of the newly liberated countries was a vision Indian national leadership had developed during its freedom struggle itself.

The vision became the core element of India’s foreign policy after independence rand of other countries which attained independence from that period onwards.

The non-aligned movement, thus, emerged from India’s initiative for formulating an independent foreign policy. This independent foreign policy was based on a solid moral and sound political foundation. It was a non-partisan foreign policy. India’s moral approach to international politics was further projected through the Panchsheel in 1954.

Within three years, eighteen countries had endorsed the Panchsheel principles in joint communiqués with Indian leaders. These principles were practically incorporated in the Ten Principles declared at Bandung. In addition during its initial years of independence itself, India played a very active role in peaceful resolution of some complex international issues and persistently lobbied in United Nations for disarmament.

All these made the idea of non-alignment, the initial basic tenet in India’s foreign policy, a mechanism providing link between the coordinated actions of the anti- imperialist and anti-colonial forces, as an assertion of independence in foreign  affairs, as a process of weakening of power blocs, as a symbol of defiance against big power domination and as a diplomatic innovation in the phase of politics of confrontation and cold war.

Over decades of its existence the NAM has been developing a comprehensive political philosophy, a programme of action, and a new and positive system of international economic and political relations. From its founding India has remained one of the most active members of NAM and has played a pivotal role in its various activities and developments.

The Supreme Court is the highest court of The Indian Republic.  Judiciary, the third organ of the government, has an important role to play in the governance. It settles the disputes, interprets laws, protects fundamental rights and acts as guardian of the Constitution. India has a single unified and integrated judicial system and that the Supreme Court is the highest court in India.

The  promulgation  of  Regulating  Act  of  1773  by  the  King  of  England paved the way for establishment of the Supreme Court of Judicature at Calcutta. The Letters of Patent was issued  on 26 March  1774 to establish  the  Supreme Court  of  Judicature  at  Calcutta,  as  a  Court  of  Record,  with  full  power  & authority  to  hear  and  determine  all  complaints  for  any  crimes  and  also  to entertain, hear and determine any suits or actions against any of His Majesty’s subjects  in  Bengal,  Bihar  and  Orissa.  The  Supreme  Courts  at  Madras  and Bombay was established by King George – III on 26 December 1800 and on 8 December 1823 respectively.

Federal Court of India was established under the Government of India Act 1935. The Federal Court  had  jurisdiction  to  solve  disputes  between  provinces  and  federal  states and  hear  appeal  against  Judgements  from  High  Courts.

After  India  attained independence in 1947, the Constitution of India came into being on 26 January 1950. The Supreme Court of India also came into existence and its first sitting was held on 28 January 1950.

The Chief Justice and other judges of the Supreme Court are appointed by the President of India. While appointing the Chief Justice, the President is constitutionally required to consult such other judges of the Supreme Court as he deems proper, but outgoing Chief Justice is always consulted. Normally, the senior most judge of the Supreme Court is appointed as the Chief Justice of India, although there is no constitutional requirement to do so. While appointing other judges, the President is bound to consult the Chief Justice and other senior judges, if he deems proper.

The original Constitution of 1950 envisaged a Supreme Court with a Chief Justice and 7 puisne Judges – leaving it to Parliament to increase this number.

According to the Constitution of India, the role of the Supreme Court is that of a federal court, guardian of the Constitution and the highest court of appeal. Articles 124 to 147 of the Constitution of India lay down the composition and jurisdiction of the Supreme Court of India. Primarily, it is an appellate court which takes up appeals against judgments of the High Courts of the states and territories.

The Supreme Court is a Court of Record. It has two implications. All its decisions and judgments are cited as precedents in all courts of the country. They have the force of law and are binding on all lower Courts, and indeed the High Courts. As a Court of Record, the Supreme Court can even send a person to jail who may have committed contempt of the court.

As a Federal Court: Supreme Court is the Federal Court of India, India being a federation; powers are divided between the Union and State governments. The Supreme Court of India is the final authority to see to it that the division of powers as specified in the constitution is obeyed by both the Union and the State governments. So, Article 131 of the Indian Constitution vests the Supreme Court with original and exclusive jurisdiction to determine the justiciable disputes between the Union and the States or between the States.

Interpreter of the Constitution and Law: The responsibility of interpreting the constitution rests on the Supreme Court. The interpretation of the constitution which the Supreme Court shall make must be accepted by all. It interprets the constitution and preserves it. Where a case involves a substantial question of law as to the interpretation of the constitution either certified by the High Court or being satisfied by the Supreme Court itself, an appeal shall lie to the Supreme Court for interpretation of the question of law raised.

As a Court of Appeal: The Supreme Court is the highest court of appeal from all courts in the territory of India. Appeal lies to the Supreme Court of the cases involving interpretation of the constitution. Appeals in respect of civil and criminal cases also lie to the Supreme Court irrespective of any constitutional question.

Advisory Role: The Supreme Court has an advisory jurisdiction in offering its opinion an any question of law or fact of public importance as may be referred to it for consideration by the President.

Guardian of the Constitution: The Supreme Court of India is the guardian of the constitution. There are two points of significance of the Supreme Court’s rule as the protector and guardian of the constitution.

• First, as the highest Federal Court, it is within the power and authority of the Supreme Court to settle any dispute regarding division of powers between the Union and the States.
• Secondly, it is in the Supreme Court’s authority to safeguard the fundamental rights of the citizens.

In order to discharge these two functions it is sometimes necessary for the Supreme Court to examine or review the legality of the laws enacted by both the Union and the State Governments. This is known as the power of Judicial Review. Indian Supreme Court enjoys limited power of Judicial Review.

Writ Jurisdictions: Under Article 32 of the constitution of Supreme Court can issue Writs for the enforcement of fundamental rights. These writs are in the nature of Habeas Corpus, Mandamas, Prohibition, and Quo-warranto Certiorari.

Power of Judicial Review and Supreme Court: The power of the Judiciary to examine the validity of such law is called Judicial Review. The Supreme Court of India enjoys limited power of Judicial Review. Judicial Review empowers the courts to invalidate laws passed by the legislature. Supreme Court of India also enjoys the power of Judicial Review. If it occurs to the Supreme Court that any law enacted by Parliament or by a State Legislature curbs or threatens to curb the citizen’s fundamental rights, the Supreme Court may declare that law as unlawful or unconstitutional.

 

 

 

Remote Sensing

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation.

In current usage, the term “remote sensing” generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth, including on the surface and in the atmosphere and oceans, based on propagated signals.

Remote sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines for example, hydrology, ecology, oceanography, glaciology, geology.It also has military, intelligence, commercial, economic, planning, and humanitarian applications.

GIS

Geographic Information System (GIS) is a computer based application of technology involving spatial and attributes information to act as a decision support tool.

It keeps information in different layers and generates various combinations pertaining to the requirement of the decision-making. In the recent times, GIS has emerged as an effective tool in management of disasters since, geo-spatial data and socio-economic information need to be amalgamated for the better decision making in handling a disaster or to plan for tackling a disaster in a better way.

Applications:

Disaster Management

The different line departments and agencies who are stakeholders in the disaster management process could utilize GIS. Some basic hardware like computer system, printer, network systems, along with GIS software is required to set up the GIS in any organisation.

Objectives:

The prime objectives of developing the GIS database are to help disaster managers at State, District and Block level for:

1. i) Pre-disaster planning and preparedness
2. ii) Prediction and early warning

iii)                 Damage assessment and relief management

GIS combines layers of information on various themes to enable the managers to take the most appropriate decisions under the given circumstances. For disaster management, a GIS database could be a useful managerial tool for various reasons, some of which are as under:

• Disaster Managers could generate maps both at micro and macro level indicating vulnerability to different extents under different threat perceptions.
• Locations likely to remain unaffected or remain comparatively safe could be identified.
• Alternate routes to shelters, camps, and important locations in the event of disruption of normal surface communication could be worked out.
• Smooth rescue and evacuation operations could be properly planned.
• Rehabilitation and post-disaster reconstruction works could be properly organized.
• Locations suitable for construction of shelters, godowns, housing colonies, etc. can be scientifically identified.
• Areas where no construction should be taken up or existing habitations require relocation could be identified.

Hydrology

Remote sensing of hydrologic processes can provide information on locations where in situ sensors may be unavailable or sparse. It also enables observations over large spatial extents. Many of the variables constituting the terrestrial water balance, for example surface water storage, soil moisture, precipitation, evapotranspiration, and snow and ice, are measurable using remote sensing at various spatial-temporal resolutions and accuracies. Sources of remote sensing include land-based sensors, airborne sensors and satellite sensors, which can capture microwave, thermal and near-infrared data or use LIDAR.

Weather forecasting and Ecology

Many ecological research projects would benefit from the creation of a GIS to explore spatial relationships within and between the data.  In particular, while some projects can be done without using a GIS, many will be greatly enhanced by using it (click here for some examples of research projects which have used GIS).

The very act of creating a GIS will make you think about the spatial relationships within your data, and will help you formulate hypotheses to test or suggest new ones to explore.  In addition, thinking about your data in a spatial manner will help you identify potential spatial issues and/or biases with your data.

GIS can also be used to make measurements and carry out calculations which would otherwise be very difficult.  For example, a GIS can be used to work out how much of your study area consists of a specific habitat type, or how much of it is over 1,000m high, or has a gradient greater than 5º, and so on.  Similarly, a GIS can be used to calculate the size of the home range of an individual or the total area occupied by a specific species or how long your survey tracks are, or how much survey effort was put into different parts of your study area.

GIS can also be used to link data together in the way that is needed for statistical analysis.  For example, many statistical packages require all your data to be in a single table, with one line per sample and then information about that sample and the location where it came from in different columns or fields.  A GIS provides you with a way to easily create such tables and populate it with information, such as the altitude at each location, the gradient of slope and the direction it faces, from other data sets.  This makes preparing your data for statistical analysis much simpler.

 

Mughal Empire (1526 A.D.-1857 A.D.)

Babur-

His actual name was Zahiruddin Mohammed, son of Omar Sheikh Mirza, the king of Ferghana in Afghanistan. His ambition was to conquer Samarkand, the seat of Timur. In 1527 A.D., Babur defeated ranasanga in the battle of Kanwa. In the battle of Chanderi (1528 A.D.), Babur defeated Mediniroy. In the battle of Gogra in 1529 A.D., Babur defeated Mohd Lodi, brother of Ibrahim Lodi and conquered Bengal. Babur wrote his memories in Turkish language. It was called Tuzak-i-Babari or babarnamah.

 

Humayun (1530 A.D.- 1555 A.D.) 

Humayun means ‘the most fortunate’. In 1537 A.D., he conquered Gujarat. His arch enemy was sher shah. Humayun defeated sher shah suri in the battle of Chausa in 1540 A.D. and for the second time in the battle of bilgram (1540 A.D.). The mughals lost delhi in the battle of bilgram for the first time. Humayun took shelter in the court of Rana Prasad of Amarkot. In 1545 A.D., humayun defeated sikandar shah of the suri dynasty in the battle of sarhind and got back delhi. He fell from his personal library at dinpanah and died.

 

Akbar (1556 A.D.- 1605 A.D.)

Second battle of Panipat( October 1556 A.D.) was fought between Akbar and Hemu. Hemu took the title of ‘Raja Vikramajeet’. Akbar was declared the emperor of Hindustan at Kalanoor in sind without being coronated by his tutor Bairam Khan. The mughals got back delhi in the second battle of Panipat by killing Hemu.upto 1562 A.D., the government was called ‘Purdah government’ as mahamanagabagum, the first wife of Humayun ,hamidabanu begum and bairam khan managed the administration.

Akbar,s conquests-

In 1562 A.D., Rani durgavati of godwana was defeated.

In 1564 A.D., Bazbahadurof malwa was defeated.

In 1570 A.D., Dawood khan of Bengal was killed.

In 1572 A.D., Muzaffar shah of Gujarat was defeated.

In 1585 A.D, Akbar conquered Kashmir defeated Md. Padshah.

In 1600 A.D., Rani chandbibi of Amhmednagar was defeated btAbulFazl who sent by Akbar. this was the last conquest of Akbar.

Akbar,s Rajput policy-

Akbar was a great pragmatist. He was the first Muslim ruler to realize that without the help of the Rajput’s, no permanent empire could be set up in India. In January, 1562 when the Akbar was going to Ajmer to visit the holy shrine of Saint Chishti, he accepted the submission of Raja Bharmal of Amber and welcomed a matrimonial alliance with that Kachhwaha ruling family and on his return from Ajmer Akbar married with his daughter on 6th February, 1562.

Bharmal with his son Bhagwant Das and grandson Man Singh accompanied the Emperor to Aagra where he was given a command of 5,000 and his son and grandson were granted commissions in the imperial army.

The Rajput policy of Akbar was wise and statesman like. He succeeded in bringing the majority of the Rajput kingdoms under his authority. What is more important, Akbar was able to enlist the support of the Rajputs in fighting his wars.

But it would be a mistake to suppose that Akbar’s Rajput policy was wholly successful. It was not. He was unable to break the power and pride of Mewar. It was not till Jahangir’s time that Mewar concluded terms with the Mughals. Even then the Mughal Emperor had to concede to the ruler of Mewar, a status of special honour and privilege.

Akbar,s Religious policy-

In 1562 A.D., Akbar banned force conversion.

In 1563 A.D. the pilgrim tax on Hindus was abolished.

In 1564 A.D. JIzia tax was abolished.

In 1575 A.D. Akbar constructed Ibadatkhana at FatehpurSikri for religious discourses and discussions to be conducted every Thursday.

Akbar invited father monsuratte and father Aquinois to speak on Christianity, Pt. Puroshottam on Hinduism, jainasenasuri on Jainism and Raza on parsi religion.

In 1579 A.D., he issued his famous decree of infallibility called mahazir or Mahzarnama.

It was drafted by sheikh Mubarak. With he decree, Akbar became Mir-i-Adil (chief interpretor of konan). In 1582 A.D. akbar founded a new faith called Din-iillahi. It was also called tauhid-i-illahi meaning universal faith. Its main theme sul-i-khul interpreted as ‘peace and harmony’ was  introduced for the first time by abdullatif, the teacher of akbar. din-i-illahi was openly criticized by raja bhagwan das.

Revenue Administration:

Akbar initially followed Sher Shah, revenue systems, particularly the Zabt system. Raja Todal Mal was made the Revenue Minister of Akbar and was known as Diwan-i-Ashraf. Todar Mal introduced ‘Bandobast’, a revenue assessment system classified into four categories:

Polaj (best tract), Parauti (second best), Checher (3^rd grade) and Banjar (least fertile). On the basis of the average produce for the last 10 years, the category of land was decided and accordingly tax was levied. Dastur-ul-Amal was the price list for every area’s agricultural commodities. Akbar appointed supervisors for revenue collection called karoris at paraganah level.

 

Military Administration (Mansabdari System)

The Mansabdari  system was the unique administration system under the Mughals. Though introduced by Babur, it was perfected by Akbar. themansabdars were the civil servants selected on merit. They discharged civil, military, and judicial functions on behalf of the state/Emperor and were given land called Jagirs. The highest rank in Mansabdari of above 5000 was conferred by Akbar on raja man singhndAzizuddinKuka (11,000 sawars).

Mir-i-Atish was in charge of artillery.

Mir-i-Bahari was in charge of navy.

Mir-i-Askan was in charge of the military offences.

 

Jahangir (1605 A.D.- 1628 A.D.)

His pet name was Sheikh baba. He hung the ‘bell of justice’ in Agra Fort. He executed his son khusrau and also the fifth guru ArjunDev for supporting him. Mehr-un-nisa begum was given the tilte of ‘Noorjahan’and she became popular as padshah begum. She founded her own group called junta consisting of herself, her father MirzaGhiaz Beg (itamad-ud-daula)and her brother Asaf khan.

Khurram (shahjahan) made Rana Amar singh of Mewar accept Mughal suzerainty in1615 A.D.

In 1616 A.D. Khurram conquered Ahmadnagar and was given the title ‘Shahjahan’.

In 1622 A.D.,Persians occupied Kandahar and the Mughals lost Kandahar forever. Jahangir died at Lahore and was buried at Shahdra near Lahore.

Shahjahan (1628 A.D – 1658 A.D)

• In 1629 A.D., Gujrat and Deccan famine resulted in the loss of man and material.
• In 1630 A.D., Portuguese in Hoogly revolted and were driven away from Hoogly by Kasim Khan, Governor of Bengal.
• In 1631 A.D., Mumtaz died.

 

Civil War– It was fought between DaraShikoh, the eldest son of Shahjahan and Aurangzeb, the third son. Begum jahanAra supported dara and RoshanArasupported  Aurangzeb. The secular dara followed Qadri Sufi Order and translated Upanishads into Persian whereas Aurangzeb followed NaqshBandi order.

Aurangzeb and his alliance with the fourth son Murad defeated the imperial armies commanded by dara and raja Jaswantsingh in the battle of varmat and samugarh in 1658 A.D. shahjahan was imprisoned on the charges of misusing public money. He died in 1665 A.D.

Aurangzeb defeated dara for the third time in the battle of deorai , performed coronation twice and came to power with the title ‘Alamgir’ meaning ‘king of the world’.

 

Aurangzeb (1658 A.D. -1707 A.D.)

• He abolished the ‘kalimas’ (inscribing quranic verses on coins).
• Mohitisib, the royal censor officer was entrusted with the responsibility of enforcing Koran.
• The customs duties were fixed at 2.5% for Muslims and 5% for Hindus.
• In 1669 A.D.he order for the destruction of temples.h The KashiVishwanath temple and Keshavrayatwmple in Mathura were the prominent ones to be destroyed.
• In 1679 A.D.Jizia was reimposed.
• He abolished both, vocal and instrument music. He also restrained court astrologer and historians; banned celebration of Diwali and Persian Navaroz festival.

Mughal Architecture

Akbar

The advent of the Mughals brought a new era in architecture. The synthesis of style which began earlier reached its zenith during this time. The architecture of Mughal style started during Akbar’s rule. The first building of this rule was Humayun’s Tomb at Delhi. In this magnificent building red stone was used. It has a main gateway and the tomb is placed in the midst of a garden. Many consider it a precursor of the TajMahal. Akbar built forts at Agra and FatehpurSikri. The BulundDarwaza reflects the grandeur of the mighty Mughal empire. This building was made following Akbar’s victory over Gujarat. The Arch of the BulandDarwaja is about 41 m high and is perhaps the most imposing gateway in the world. The tomb of SalimChishti, Palace of JodhaBai, IbadatKhana, Birbal’s House and other buildings at FatehpurSikri reflect a synthesis of Persian and Indian elements.

Jahangir

During the reign of Jehangir, Akbar’s Mausoleum was constructed at Sikandra near Agra. He built the beautiful tomb of Itimad-ud-daula which was built entirely of marble.

Shahjahan

Shahjahan was the greatest builder amongst the Mughals. He used marble extensively. Decorative design in inlay work, (called pietraduro) beautiful arches and minarets were the features of his buildings. The Red Fort and Jama Masjid of Delhi and above all the TajMahal are some of the buildings built by Shahjahan. The TajMahal, the tomb of Shahjahan’s wife, is built in marble and reflects all the architectural features that were developed during the Mughal period. It has a central dome, four elegant minarats, gateway, inlay work and gardens surrounding the main building.

The Mughal style of architecture had a profound influence on the buildings of the later period. The buildings showed a strong influence of the ancient Indian style and had courtyards and pillars. For the first time in the architecture of this style living beings- elephants, lions, peacocks and other birds were sculptured in the brackets.

Mughal Paintings

The art of textual illustration got a new look under the Mughals. Akbar and his successors brought revolutionary changes to painting and sensual illustrations. From this period book illumination or individual miniatures replaced wall painting as the most vital form of art. Emperor Akbar patronised artists from Kashmir and Gujarat; Humayun brought two Persian painters to his court. For the first time painters’ names were recorded in inscriptions. Some great painters of this period were Abd-us-SamadDasawanth and Basawan.

Beautiful illustrations are found on the pages of Baburnama and Akbarnama. Within a few years an integrated and dynamic style resulted from the synthesis of Persian and Indian style and the independent style of Mughal painting was developed. Between 1562 and 1577 a series of nearly 1400 cloth paintings were produced representing the new style and were placed in the imperial studio. Akbar also encouraged the art of making portraits.

The art of painting reached its climax during the period of Jahangir who himself was a great painter and connoisseur of art. Artists began to use vibrant colours such as peacock blue and red and were able to give three dimensional effects to paintings. Mansur, Bishan Das and Manohar were the most gifted painters of Jahangir’s time. Mansur had made an outstanding portrait of the artist AbulHasan and specialised in paintings of birds and animals.

Though Shah Jahan was more interested in architectural splendours, his eldest son DaraShikoh patronised painting like his gradfather. He preferred depicting natural elements like plants and animals in his painting. However withdrawal of royal patronage to painting under Aurangzeb led to the dispersal of artists to different places in the country.

Economic Condition during Mughal Period

The village was the unit around which peasant society revolved. It was also the real unit of assessment of the state’s revenue demand, which was distributed among villagers by the headman (muqaddam or kalantar  ) and the village accountant ( patwar ı). It thus had a financial pool, from which not only tax payments but also minor common expenses (kharch-i dih) were met. This seems to have formed the basic factor behind the celebrated, but often elusive, Indian village community.

Commerce seems to have penetrated the village economy to a great extent, since peasants needed to sell their crops in order to pay their taxes. There was little left them with which to buy any goods on the market. Even so, commerce must have intensified the already existing differences due to the unequal possession of agricultural and pastoral goods (seed, ploughs and cattle). The peasants were usually divided among castes. Even the administration recognized caste hierarchy by varying the revenue rates according to caste, as documents from Rajasthan especially show.

By and large, artisans were in the same position as peasants: they were technically’free’, but hemmed around by many constraints. Though some artisans were bound to render customary services as village servants, most could sell their wares in the market. The need for advances, however, often forced them to deal only with particular merchants, brokers or other middlemen. A small number worked in the workshops (karkhana  s) of nobles and merchants.

Merchants formed a numerous and fairly well-protected class in the Mughal empire. This class was also quite heterogeneous in composition. There were, on the one hand, the large bands of the banjara  s (transporters of goods in bulk), who travelled with pack oxen over enormous distances; on the other, there were specialist bankers (sarraf s), brokers (dallal s) and insurers (the business of bıma, or insurance, being usually carried on by sarraf s). Some of them, at the ports, also owned and operated ships.
