Application of Satellites for different purposes

 

Despite being a developing economy with its attendant problems, India has effectively developed space technology and has applied it successfully for its rapid development and today is offering a variety of space services globally.

Indian Space Program:

During the formative decade of 1960s, space research was conducted by India mainly with the help of sounding rockets. The Indian Space Research Organisation (ISRO) was formed in 1969. Space research activities were provided additional fillip with the formation of the Space Commission and the Department of Space by the government of India in 1972. And, ISRO was brought under the Department of Space in the same year.

In the history of the Indian space programme, 70s were the era of Experimentation during which experimental satellite programmes like Aryabhatta, Bhaskara, Rohini and Apple were conducted. The success of those programmes, led to era of operationalisation in 80s during which operational satellite programmes like INSAT and IRS came into being. Today, INSAT and IRS are the major programmes of ISRO.

For launching its spacecraft indigenously, India is having a robust launch vehicle programme, which has matured to the state of offering launch services to the outside world. Antrix, the commercial arm of the Department of Space, is marketing India’s space services globally. Fruitful co-operation with other space faring nations, international bodies and the developing world is one of the main characteristics of India’s space programme.

The most significant milestone of the Indian Space Programme during the year 2005-2006 was the successful launch of PSLV-C6. On 5 May 2005, the ninth flight of Polar Satellite Launch Vehicle (PSLV-C6) from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota successfully placed two satellites – the 1560 kg CARTOSTAR-1 and 42 kg HAMSAT – into a predetermined polar Sun Synchronous Orbit (SSO). Coming after seven launch successes in a row, the success of PSLV-C6 further demonstrated the reliability of PSLV and its capability to place payloads weighing up to 1600 kg satellites into a 600 km high polar SSO.

The successful launch of INSAT-4A, the heaviest and most powerful satellite built by India so far; on 22 December 2005 was the other major event of the year 2005-06. INSAT-4A is capable of providing Direct-To-Home (DTH) television broadcasting services.

Besides, the setting up of the second cluster of nine Village Resource Centres (VRCs) was an important ongoing initiative of the Department of Space during the year. VRC concept integrates the capabilities of communications and earth observation satellites to provide a variety of information emanating from space systems and other IT tools to address the changing and critical needs of rural communities.

In October 2008, the first lunar mission launched by ISRO. The spacecraft, Chandrayaan took off from the Satish Dhawan Space Centre and it operated till August 2009. The project was announced by former PM Atal Bihari Vajpayee, as part of his independence day speech in 2003. The greatest achievement of this lunar project was the discovery of a large number of water molecules in moon. ISRO plans to launch its second lunar mission, Chandrayaan 2 by 2018.

In 2014, Mangalyaan, India’s first interplanetary mission was launched, making ISRO the fourth space agency to reach Mars. Mangalyaan gained worldwide repute as being the least expensive Mars mission till date.

Recently India has launched 104 staellites at one go, which is a world record. The previous world record is with the Russian space agency with 37 satellites at one go.

India has been launching heavy satellites on its Geosynchronous Satellite Launch Vehicle (GSLV) but so far it has only been used for domestic satellites.In recent months though, there have been queries from foreign companies for launches on the GSLV.

 

Application of satellites for different purposes:

Satellites based on application can be categorized as follows:

Earth Observation satellite->

Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites. Today, India has one of the largest constellations of remote sensing satellites in operation. Currently, *thirteen* operational satellites are in Sun-synchronous orbit – RESOURCESAT-1, 2, 2A CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques, SARAL and SCATSAT-1, and *four* in Geostationary orbit- INSAT-3D, Kalpana & INSAT 3A, INSAT -3DR. Varieties of instruments have been flown onboard these satellites to provide necessary data in a diversified spatial, spectral and temporal resolutions to cater to different user requirements in the country and for global usage. The data from these satellites are used for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.

Communication satellite->

The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit. Established in 1983 with commissioning of INSAT-1B, it initiated a major revolution in India’s communications sector and sustained the same later. GSAT-18 joins the constellation of INSAT System consisting 14 operational satellites, namely – INSAT-3A, 3C, 4A, 4B, 4CR, 3DR and GSAT-6, 7, 8, 10, 12, 14, 15 and 16.

The INSAT system with more than 200 transponders in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, satellite newsgathering, societal applications, weather forecasting, disaster warning and Search and Rescue operations.

 

Navigation satellite->

Satellite Navigation service is an emerging satellite based system with commercial and strategic applications. ISRO is committed to provide the satellite based Navigation services to meet the emerging demands of the Civil Aviation requirements and to meet the user requirements of the positioning, navigation and timing based on the independent satellite navigation system. To meet the Civil Aviation requirements, ISRO is working jointly with Airport Authority of India (AAI) in establishing the GPS Aided Geo Augmented Navigation (GAGAN) system. To meet the user requirements of the positioning, navigation and timing services based on the indigenous system, ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS).

(a) GPS Aided GEO Augmented Navigation (GAGAN):

This is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI). The main objectives of GAGAN are to provide Satellite-based Navigation services with accuracy and integrity required for civil aviation applications and to provide better Air Traffic Management over Indian Airspace. The system will be interoperable with other international SBAS systems and provide seamless navigation across regional boundaries. The GAGAN Signal-In-Space (SIS) is available through GSAT-8 and GSAT-10.

(b) Indian Regional Navigation Satellite System (IRNSS) : NavIC

This is an independent Indian Satellite based positioning system for critical National applications. The main objective is to provide Reliable Position, Navigation and Timing services over India and its neighbourhood, to provide fairly good accuracy to the user. The IRNSS will provide basically two types of services

Standard Positioning Service (SPS)

Restricted Service (RS)

Space Segment consists of seven satellites, three satellites in GEO stationary orbit (GEO) and four satellites in Geo Synchronous Orbit (GSO) orbit with inclination of 29° to the equatorial plane. This constellation of seven satellites was named as “NavIC” (Navigation Indian Constellation) by the Honourable Prime Minister of India, Mr. Narendra Modi and dedicated to the Nation on the occasion of successful launch of IRNSS-1G, the seventh and last satellite of NavIC. All the satellites will be visible at all times in the Indian region. All the seven Satellites of NavIC, namely, IRNSS-1A, 1B, 1C, ID,1E, 1F and 1G were successfully launched on July 02, 2013, Apr 04, 2014, Oct 16, 2014, Mar 28, 2015, Jan 20, 2016, Mar 10, 2016 and Apr 28, 2016 respectively and all are functioning satisfactorily from their designated orbital positions.

Ground Segment is responsible for the maintenance and operation of the IRNSS constellation. It provides the monitoring of the constellation status, computation of the orbital and clock parameters and navigation data uploading. The Ground segment comprises of TTC & Uplinking Stations, Spacecraft Control Centre, IRNSS Timing Centre, CDMA Ranging Stations, Navigation Control Centre and Data Communication Links. Space segment is compatible with single frequency receiver for Standard Positioning Service (SPS), dual frequency receiver for both SPS & RS service and a multi mode receiver compatible with other GNSS providers.

 

Experimental satellite->

ISRO has launched many small satellites mainly for the experimental purposes. This experiment include Remote Sensing, Atmospheric Studies, Payload Development, Orbit Controls, recovery technology etc. Example- INS-1A, INS-1B, YOUTHSAT, APPLE

 

Small satellite->

The small satellite project is envisaged to provide platform for stand-alone payloads for earth imaging and science missions within a quick turn around time. For making the versatile platform for different kinds of payloads, two kinds of buses have been configured and developed.

Indian Mini Satellite -1 (IMS-1): IMS-1 bus has been developed as a versatile bus of 100 kg class which includes a payload capability of around 30 kg. The bus has been developed using various miniaturization techniques. The first mission of the IMS-1 series was launched successfully on April 28th 2008 as a co-passenger along with Cartosat 2A. Youthsat is second mission in this series and was launched successfully along with Resourcesat 2 on  20th April 2011.

Indian Mini Satellite -2 (IMS-2) Bus: IMS-2 Bus is evolved as a standard bus of 400 kg class which includes a payload capability of around 200kg. IMS-2 development is an important milestone as it is envisaged to be a work horse for different types of remote sensing applications. The first mission of IMS-2 is SARAL.  SARAL is a co-operative mission between ISRO and CNES with payloads from CNES and spacecraft bus from ISRO.

 

Student/Academic satellite->

ISRO has influenced educational institutions by its activities like making satellites for communication, remote sensing and astronomy. The launch of Chandrayaan-1 increased the interest of universities and institutions towards making experimental student satellites.

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.

 

 

• Classcial Theories:

1. Halley’s Thermal concept: Indian monsoon is because of contrast between Indian Subcontinent and adjoining Indian Ocean. Halley’s theory, suggested in 1686, considers the summer monsoon to be a regional phenomenon.
2. Aerological concept: This was suggested by R. Scherhag in 1948. According to this theory, monsoon circulation develops due to changes in air temperature at all levels over the Indian Subcontinent and adjoining Indian Ocean.

 

• Modern theories:

1. Dynamic Theory: Flohn (1951) according to Flohn, the monsoon is a global phenomenon due to global shift in pressure belts. The shift in pressure belts bring the ITC much more into the northern margin is around 30 degrees north over the Indian subcontinent. This brings the SE trades over the Indian subcontinent as south westerly monsoons. Similarly, the shift in pressure belts globally when it is winter for the N. Hemisphere pushes the ITC to a little more south of the equator. This brings the sub- tropical high on to the southern slopes of Himalayas and hence the NE trades blow from northeast to southwest as northeast monsoons.

 

2. Tibet and Easterly Jet: P. Koteshwaram and Flohn concluded that heating of Tibet in summer strengthens the monsoonal circulation with an average height of 4Kms above the MSL, Tibetan surface is warmed in summer and generates ascending warm air. The air turns to its right and sinks over the Arabian sea and joins the southwesterly winds there by strengthening the monsoon. This circulation is part of the tropical easterly jet stream.

 

3. Role of Sub- Tropical westerly Jet: The sub-tropical westerly jet normally located on the south slopes of Himalayas and the northeast plains disintegrates in summer due to intense heating of the northern plains and the global shift in pressure belts to the north in summer of the northern hemisphere. This facilities the onset of the monsoon over india by facilitating the development of the monsoon trough.

 

4. The Somali Jet: The offshore areas of Somalia develop clod waters due to upwelling giving birth to the Somali current. The cold waters led to low temperature along Somali coast ( 15 degrees centigrade) whereas along Mumbai, the temperature is 30 degrees cent centigrade. This thermal gradient leads to development of the Somali jet stream blowing from western Arabian sea to the eastern Arabian sea. This adds moisture bearing winds to the southwest monsoon.

 

5. The Monsoon trough: This is the ITC which forms as a huge gash of low pressure from the desert of Arabian to Bay of Bengal. This covers the northern plains and induces the SE trades to cross the equator and give birth the south westerly winds.

 

6. El Nino: The development of El Nino conditions influence the monsoon. During El Nino, the southern oscillation (i.e., the differences in pressure between port  Darwin and Tahiti, French Polynesia). If the southern oscillation is negative, Darwin pressure is higher than Tahiti due to high pressure over Australia, western pacific and adjacent Indian ocean. The high pressure conditions also cover the Indian ocean and the landmass of peninsular India. This prevents the movement of southeast trades towards the landmass of India. If the southern oscillation is positive, Tahiti pressure is more than that of Darwin. Low pressure is over North Australia and over adjacent Indian Ocean. This induces northward movement of southeast trades and hence strengthens monsoonal circulation. The combination of El Nino current (which appears as a warm saline current along the west coast of S. America replacing the cold Humboldt current during a negative El Nino) and the southern oscillation is caused ENSO.

 

Onset of Monsoon

The summer monsoon over the Indian subcontinent first arrives over Kerala situated at the southern tip of the Indian Peninsula around 1st June with a standard deviation of about 7 days. The arrival of the monsoon over the region is noticed by wide spread persistent and heavy rainfall replacing the occasional pre-monsoon rains.

 

Retreat Of Monsoon

This  lasts between September and end of December. This is the season of retreating monsoons. The monsoon trough over the northern plains weakens and begins to shift southward. The retreating monsoon brings rain to coastal Tamil Nadu, Krishna- Godavari delta, region west of Aravallis and to northeast India. The retreat of the monsoon begins on 1^st September (i.e., in Rajasthan), 15^th September in Punjab- Haryana plains, 10^th October from Ganges plains, 1^st December from Tamil Nadu and by 15^th December, the southwest monsoon withdraws from india completely. The retreating monsoon brings rainfall to AP south of Krishna delta and Tamil Nadu. The rainfall in Tamil Nadu in October/November, is 38.25 cms which is about 39% of its annual rainfall while for coastal Tamil Nadu it is 50% of the annual.

This is the season for tropical cyclones that affect the Indian landmass. Cyclones that affect the east coast and the west coast from in the southern portions of the Bay of Bengal, particularly during the retreating monsoon season. Maximum number of that form in the Bay of Bengal form in November. More number of cyclones form in the bay of Bengal than the Arabian sea.

 

 

 

 

 

Role of Foreign Capital and Multinational companies in

Industrial development of India

 

The development of any society or country without economic development is a myth. Economic development brings prosperity which in turns is directly proportional to the amount of goods and services produced quantitatively or in broad sense we can say in money equivalent.

So the factor of production depends on the following parameters.

• Land
• Labour
• Capital

 

 

For a country like India which is the second largest populous country in the world, expected to become most populous by 2050 if population growth is continuing at the current pace, where labour is available in abundance. Similarly, land is also available where more economic prosperity can be brought than the currently pursued economic activity. So after considering all these factors, capital played a crucial role.

 

So to fulfill the aspirations of common masses and general wellbeing of the society various governments are competing against each other to attract the foreign capital.

 

 

 

This theory is particularly gained ground after the Latin American crises which resulted in the Washington consensus/Washington model. This is further ascertained by East Asian miracle. India has also experienced the taste of after economic reforms of 1991, which is better known as LPG reforms. However from the experience of various countries various model of foreign capital and model have emerged. It also requires some kind of reduction regulation and restraint.

 

Why there is a need of foreign capital?

 

Foreign capital is required because of following reasons.

1. Inadequate domestic capital to fuel the economic growth.

Foreign capital is perceived as a resource of filling the gap of the capital scarce country. It helps in maintaining the foreign exchange, accelerating government revenue, planning the investment necessary to achieve development target.

For example ‘savings-investment’ gap

To achieve a planned growth rate of 7 percent per annum and the capital-output ration of 3 percent, rate of saving should be 21 percent. For domestic mobilization of 16 percent, there will be a shortfall of 5 percent. Thus the foremost contribution of foreign capital to national development is its role in filling the resource gap between targeted investment and locally mobilized savings.

 

 

 

2. Stability of Foreign exchange.

Foreign capital is needed to fill the gap between the targeted foreign exchange requirements and those derived from net export earnings plus net public foreign aid. This is generally called the foreign exchange or trade gap.

3. Reducing the Balance of Payment deficit.

An inflow of private foreign capital helps in removing deficit in the balance of payments over time if the foreign-owned enterprise can generate a net positive flow of export earnings.

4. Helps in realizing the estimated tax revenue of government

The third gap that the foreign capital and specifically, foreign investment helps to fill is that between governmental tax revenue and the locally raised taxes. By taxing the profits of the foreign enterprises the governments of developing countries are able to mobilize funds for projects (like energy, infrastructure) that are badly needed for economic development.

5. Foreign investment meets the gap in management, entrepreneurship, technology and skill.

These can be transferred to the host country through suitable training programmes and the processes. Further foreign companies bring with them

 

 

 

sophisticated technological knowledge about production processes while transferring modern machinery equipment to the capital-poor developing countries.

In fact, in this era of globalization, there is a general belief that foreign capital transforms the productive structures of the developing economics leading to high rates of growth. Besides the above, foreign capital, by creating new productive assets, contributes to the generation of employment a prime need of a country like India.

Forms and types of foreign Capital

Foreign capital flow in a country can take place either in the form of investment, concessional assistance, foreign aid.

1. Foreign Investment includes Foreign Direct Investment (FDI) and Foreign Portfolio Investment (FPI) / Foreign Institutional Investment (FII).

FPI includes the amounts raised by Indian corporate through Euro Equities, Global Depository Receipts (GDR’s), and American Depository Receipts (ADR’s).

2. Non-Concessional Assistance mainly includes External Commercial Borrowings (ECB’s), loans from governments of other countries/multilateral agencies on market terms and deposits obtained from Non-Resident Indians (NRIs).

 

 

 

3. Concessional Assistance includes grants and loans obtained at low rates of interest with long maturity periods. Such assistance is generally provided on a bilateral basis or through multilateral agencies like the World Bank, International Monetary Fund (IMF), and International Development Association (IDA) etc.

Grants do not carry any obligation of repayment and are mostly made available to meet some temporary crisis. Foreign Aid can also be received in terms of direct supplies of agricultural commodities or industrial raw materials to overcome temporary shortages in the economy. Foreign Aid may also be given in the form of technical assistance.

 

 

 

 

 

 

 

 

 

 

 

Role of Multinational Corporations in the Indian Economy

Prior to 1991 Multinational companies did not play much role in the Indian economy. In the pre-reform period the Indian economy was dominated by public enterprises.

Earlier Industries and firms are regulated through Industrial Policy, 1956 put some kind of restraint on private firms, as a consequence of which they didn’t able to expand beyond a limit.

While multinational companies played a significant role in the promotion of growth and trade in South-East Asian countries they did not play much role in the Indian economy where import-substitution development strategy was followed. Since 1991, with the adoption of industrial policy of liberalization, privatization

And globalization role of private foreign capital has been recognized as important for rapid growth of the Indian economy. So Multinational corporations have been allowed to operate in India subjected to some regulations.

 

Impact of Multinational countries on the country and general population.

1. Promotion Foreign Investment:

In the recent years, external assistance to developing countries has been declining. This is because the donor developed countries have not been willing to part with a

 

larger proportion of their GDP as assistance to developing countries. MNCs can bridge the gap between the requirements of foreign capital for increasing foreign investment in India.

The liberalized foreign investment pursued since 1991, allows MNCs to make investment in India subject to different ceilings fixed for different industries or projects. However, in some industries 100 per cent export-oriented units (EOUs) can be set up. It may be noted, like domestic investment, foreign investment has also a multiplier effect on income and employment in a country.

For example, the effect of Suzuki firm’s investment in Maruti Udyog manufacturing cars is not confined to income and employment for the workers and employees of Maruti Udyog but goes beyond that. Many workers are employed in dealer firms who sell Maruti cars.

Moreover, many intermediate goods are supplied by Indian suppliers to Maruti Udyog and for this many workers are employed by them to manufacture various parts and components used in Maruti cars. Thus their incomes also go up by investment by a Japanese multinational in Maruti Udyog Limited in India.

2. Non-Debt Creating Capital inflows:

In pre-reform period in India when foreign direct investment by MNCs was discouraged, we relied heavily on external commercial borrowing (ECB) which was of debt-creating capital inflows. This raised the burden of external debt and debt service payments reached an alarming figure of our current account receipts.

 

 

 

This created doubts about our ability to fulfill our debt obligations and there was a flight of capital from

India and this resulted in balance of payments crisis in 1991. As direct foreign investment by multinational corporations represents non-debt creating capital inflows we can avoid the liability of debt-servicing payments. Moreover, the advantage of investment by MNCs lies in the fact that servicing of non-debt capital begins only when the MNC firm reaches the stage of making profits to repatriate Thus, MNCs can play an important role in reducing stress strains and on India’s balance of payments (BOP).

3. Technology Transfer:

Another important role of multinational corporations is that they transfer  sophisticated technology to developing countries which are essential for raising productivity of working class and enable us to start new productive ventures requiring high technology. Whenever, multinational firms set up their subsidiary production units or joint-venture units, they not only import new equipment and machinery embodying new technology but also skills and technical know-how to use the new equipment and machinery.

As a result, the Indian workers and engineers come to know of new superior technology and the way to use it. In India, the corporate sector spends only few resources on Research and Development (R&D). It is the giant multinational

 

 

 

corporate firms (MNCs) which spend a lot on the development of new technologies can greatly benefit the developing countries by transferring the new technology developed by them. Therefore, MNCs can play an important role in the technological up-gradation of the Indian economy.

4. Promotion of Exports:

With globalization and producing products efficiently and therefore with lower costs multinationals can play a significant role in promoting exports of a country in which they invest. For example, the rapid expansion in China’s exports in recent years is due to the large investment made by multinationals in various fields of Chinese industry.

Historically in India, multinationals made large investment in plantations whose products they exported. In recent years, Vistara airlines made a large investment in airline industries with a joint collaboration with Tata Industries.

BrahMos missile is a joint venture of Govt. of India with Russia, which is being sold to Vietnam, will bring income to India.

As a matter of fact until recently, when giving permission to a multinational firm for investment in India, Government granted the permission subject to the condition that the concerned multinational company would export the product so as to earn foreign exchange for India.

 

 

 

However, in case of Pepsi, a famous cold -drink multinational company, while for getting a product license in 1961 to produce Pepsi Cola in India it agreed to export a certain proportion of its product, but later it expressed its inability to do so. Instead, it ultimately agreed to export things other than what it produced such as tea.

5. Investment in Infrastructure:

With a large command over financial resources and their superior ability to raise resources both globally and inside India it is said that multinational corporations could invest in infrastructure such as power projects, modernization of airports and posts, telecommunication.

The investment in infrastructure will give a boost to industrial growth and help in creating income and employment in the India economy. The external economies generated by investment in infrastructure by MNCs will therefore crowd in investment by the indigenous private sector and will therefore stimulate economic growth.

In view of above, Make in India initiative, skill India Initiative, current demographic scenario of India, foreign direct investment (FDI) will be encouraged and actively sought, especially in areas of (a) infrastructure, (b) high technology and (c) exports, and (d) where domestic assets and employment are created on a significant scale

 

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

Rise of Maratha Empire

Chhatrapati Shivaji Maharaj (Shivaji Shahaji Bhosale) was the founder of strong Maratha Empire in the west part of India in 17th Century.

Chhatrapati Shivaji Maharaj (Shivaji Shahaji Bhosale) was born in the fort of Shivneri, near from city Junner (Pune District), in the year 1630 (19th February’ 1630). His mother Jijabai Bhosale named him Shivaji in the honor of goddess Shivai Devi. Chhatrapati Shivaji was devotAed to his mother Jijabai Bhosale, who was extreme religious. This kind of environment had put deep impact on Shivaji maharaj.

Expansion of Empire and Battles of Shivaji

• In the 1659 Adilshah sent Afzalkhan with the army of 75000 soldiers to destroy Shivaji with his empire. Chhatrapati Shivaji killed Afzal Khan with full diplomatically. He signaled his troops to start the great assault on the Adilshahi Sultanate.
• Shivaji defeated Kaltalf Khan, a sardar of Shahista Khan in the Battle of Umberkhind with few soldiers (Mavale).
• Aurangjeb sent his maternal uncle Shahista Khan with powerful army over 1,50,000 on request of Badibegum Sahiba, Adishahi sultanate. In the April 1663Chhatrapati Shivaji personally made surprise attack on Shahista Khan in the LalMahal Pune.
• Chhatrapati Shivaji sacked surat ,the wealthy city of mughal empire in 1664. Surat was the financial capital of mughal& trading centre.
• Chhatrapati Shivaji agreed to give 23 forts and Rs. 4,00,000/- hone, to let his son Sambhaji become Mughal Sardar and ready to meet with Aurangjeb in the treaty of Purander between Chhatrapati Shivaji and Mirza Raje Jaisingh on behalf of Mughal.
• Chhatrapati Shivaji gained lot of province till jinji in Karnataka after coronation in the period of 1677-1678.
• Aurangjeb invited Chhatrapati Shivaji to Agra on occasion of his 50th birth anniversary. However, in the court on 1666 Aurangjeb made in stand behind military commanders of his court.Shivaji got angry and he refused gift which offered by Aurangjeb and stormed out of the court. He was house arrested by Aurangjeb .Chhatrapati Shivaji made supreme plan and succeed to escape from Agra.

Ashtpradhans of Shivaji

It was dministrative and advisory council set up by the Indian Shivaji which contributed to his successful military attacks on the Muslim Mughal Empire and to the good government of the territory over which he established his rule.

• Peshwa- Prime Minister
• Amatya- Finance Department
• Sachiv- Home Secretary
• Sumant- Foreign Secretary
• Nyayadheesh- Judicial Magistarate
• Senapati- Commander In chief
• Panditrao- relifious matters
• Mantri- Day to day activities

Revenue Administration

T he assessment of revenue was made after a careful survey and classification of the lands according to their quality and yield. The share of the state was fixed at two-fifths of the gross produce. The cultivator was given the option of paying either in cash or kind.

Besides the land revenue, Shivaji had other sources of income, of which the most important were the chauth and sardeshmukhi. The chauth amounted to one-fourth of the standard revenue assessment of the place, while the sardeshmukhi was an additional levy of 10 per cent de­manded from areas outside his kingdom because he claimed to be the hereditary sardeshmukh (chief headman) of the entire Maratha country. These taxes were levied on those living outside Maratha kingdom as a safeguard (a kind of protection money) against Shivaji’s forces plundering or raiding their territory.

Marathas Consolidation and Northward Expansion

Age of Peshwas

Balaji Vishwanath

With Balaji Vishwanath in charge of the Maratha military and Kanhoji in charge of the Marathas Navy. This agreement set the course for Balaji Viswanatha’s rise as a Peshwa during his subsequent visit to Delhi with an army of 12,000 Marathas. During this visit to Delhi, on an invitation from the Syed brothers in their struggle with the Mughal Emperor Farrukhsiyyar, the Maratha forces led by Balaji Viswanath clashed with the forces of Mughal Emperor and defeated them. This was the first Maratha victory over the Mughals in Delhi. This event marks the asendency of the Marathas in Delhi an asendency that was to last for almost a century till they were supplanted by the British in 1803.

The Peshwas – Baji Rao, Balaji Baji Rao, Madha Rao
After Shahu, the de facto executive power passed into the hands of the hereditary Prime Ministers the Peshwas. Balaji Viawanath Bhatt was succeeded by his son Baji Rao the first. Baji Rao was a very able and ambitious soldier and he was the one who consolidated Maratha power in North India.

Baji Rao died at a relativey young age of 40 in the year 1740. His was succeeded by his son Balaji Baji Rao. Balaji Baji Rao played a tragic role in Maratha history and the fissiparous tendencies he let loose ultimately let to the downfall of the Maratha empire.
His first mistake was to go back on the agreement between his grandfather Balaji Viswanath Bhatt and Kanhoji Angre according to which the Peshwa was to have no direct control over the Maratha Navy. He attacked the his own navy and weakened one arm of the Maratha might.
During his rule, North India was invaded by Ahmed Shah Abdali first in 1756. Balaji Baji Rao then sent his brother Raghunath Rao along with Malharrao Holkar to defeat Abdali. Raghunath rao not only defeated Abdali but chased him up to the Khyber pass till Attock in Paktoonistan. .
This success of Raghunath Rao aroused the jealousy of Balaji Baji Rao’s wife Gopikabai, who started conspiring against Raghunath Rao to undermine his influence. This led to corresponding jealousy from Anandibai who was Ragunath Rao’s wife. The unfortunate fallout of this court intrigue ws to end in the disastrous 3rd battle of Panipat in 1761.

The 3rd Battle of Panipat
When Abdali launched his second invasion in 1759 the Marathas who after their successes in 1756 had been hibernating in Maharashtra and Central India again woke up and in alliance with the Jat King Suraj Mal of Bharatpur formed an alliance. This alliance led by Shrimant Sadshiv Rao Bhau and Shrimant Vishwas Rao (the Peshwa Shrimant Balaji Baji Rao’s son) won spectacular victories and captured Delhi and Kunjapura (where the Afghan treasury and armoury was located). Here the alliance developed cracks due to the Maratha insistence on not allowing the Jats to loot Delhi. This ultimately split the alliance and Suraj Mal withdrew from the alliance. The Marathas consequently marched upto Panipat, but instead of continuing their attacks to completely defeat the partly defeated Abdali and Najib Khan, they stayed put at Panipat, blocking the way of the Afghans back to Afghanistan. Seeing their way back to their homeland blocked, the Afghans now became restless. They in turn, decided to block the way of the Marathas back into the Deccan.
This stand-off continued for one whole year from the 14th of January 1760 up to the 14th of January 1761. This led to the fall in the morale of the stranded Marathas and ultimatley led to their defeat at Panipat.

The Afghans with Najib Khan meanwhile also recaptured Delhi and Kunjpura. On the decisive day of 14th January 1761 (Makar Sankranti), the Marathas decided to break-through the Afghan blockade and re-enter Deccan. The disastrous battle saw about one hundred thousand Maratha troops being slaughtered in a matter of eight hours. But the Afghans too suffered heavy losses and decided enough was enough and went back to Afghanistan never to return to India.
The defeat of the Marathas and the withdrawal of the Afghans created a power vacuum in North India in the period 1761-1790. It was this vacuum that was filled up by the rising British power. But more of this later.

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.

 

 

 

 

 

 

 

 

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.
