Each landform has its unique physical shape, size, materials and is a result of the action of certain geomorphic processes and agent(s). Every landform has a beginning. Landforms once formed may change in their shape, size and nature slowly or fast due to continued action of geomorphic processes and agents. Due to changes in climatic conditions and vertical or horizontal movements of landmasses, either the intensity of processes or the processes themselves might change leading to new modifications in the landforms.

Evolution

It implies stages of transformation of either a part of the earth’s surface from one landform into another or transformation of individual landforms after they are once formed. That means, each and every landform has a history of development and changes through time. A landmass passes through stages of development somewhat comparable to the stages of life — youth, mature and old age.

Geomorphic Agents

Changes on the surface of the earth owe mostly to erosion by various geomorphic agents. Running water, ground-water, glaciers, wind and waves are powerful    erosional and depositional agents shaping and changing the surface of the earth aided by weathering and mass wasting processes. These geomorphic agents acting over long periods of time produce systematic changes leading to sequential development of landforms.

Fluvial landforms

The landforms created as a result of degradational action (erosion) or aggradation work (deposition) of running water is called fluvial landforms.

These landforms result from the action of surface flow/run-off or stream flow (water flowing through a channel under the influence of gravity). The creative work of fluvial processes may be divided into three physical phases—erosion, transportation and deposition.

The landforms created by a stream can be studied under erosional and depositional categories.

Erosional category

Valleys, gorge and Canyon

The extended depression on ground through which a stream flows throughout its course is called a river valley. A gorge is a deep valley with very steep to straight sides. A canyon is characterized by steep step-like side slopes and may be as deep as a gorge.

At a young stage, The profile of valley  is typically ‘V’ shaped. As the cycle attains maturity, the lateral erosion becomes prominent and the valley floor flattens out. The valley profile now becomes typically ‘U’ shaped with a broad base and a concave slope.

Potholes, Plunge pools

Potholes are more or less circular depressions over the rocky beds of hills streams.Once a small and shallow depression forms, pebbles and boulders get collected in those depressions and get rotated by flowing water. Consequently, the depressions grow in dimensions to form potholes.Plunge pools are nothing but large, deep potholes commonly found at the foot of a waterfall. They are formed because of the sheer impact of water and rotation of boulders.

Incised or Entrenched Meanders

They are very deep wide meanders (loop-like channels) found cut in hard rocks.In the course of time, they deepen and widen to form gorges or canyons in hard rock.The difference between a normal meander and an incised/entrenched meander is that the latter found on hard rocks.

River Terraces

They are surfaces marking old valley floor or flood plains.They are basically the result of vertical erosion by the stream. When the terraces are of the same elevation on either side of the river, they are called as paired terraces.When the terraces are seen only on one side with none on the other or one at quite a different elevation on the other side, they are called as unpaired terraces.

Depositional Features

Alluvial Fans

They are found in the middle course of a river at the foot of slope/ mountains.When the stream moves from the higher level break into foot slope plain of low gradient, it loses its energy needed to transport much of its load.Thus, they get dumped and spread as a broad low to the high cone-shaped deposits called an alluvial fan.

Deltas

They are found in the mouth of the river, which is the final location of depositional activity of a river. \The coarser material settle out first and the finer materials like silt and clay are carried out into the sea.

 

 Flood Plains, Natural Levees

Natural levees are found along the banks of large rivers. They are low, linear and parallel ridges of coarse deposits along the banks of a river.The levee deposits are coarser than the deposits spread by flood water away from the river.

 

 Meanders and oxbow lakes

• They are formed basically because of three reasons: (i) propensity of water flowing over very gentle gradient to work laterally on the banks; (ii) unconsolidated nature of alluvial deposits making up the bank with many irregularities; (iii) Coriolis force acting on fluid water deflecting it like deflecting the wind.
• The concave bank of a meander is known as cut-off bank and the convex bank is known as a slip-off
• As meanders grow into deep loops, the same may get cut-off due to erosion at the inflection point and are left as oxbow lakes.

Braided Channels

When selective deposition of coarser materials causes the formation of a central bar, it diverts the flow of river towards the banks, which increases lateral erosion. Similarly, when more and more such central bars are formed, braided channels are formed. Riverine Islands are the result of braided channels.

 

Karst Topography

Any limestone, dolomite or gypsum region showing typical landforms produced by the action of groundwater through the process of solution and deposition is called as Karst Topography (Karst region in the Balkans).

Sinkholes

A sinkhole is an opening more or less circular at the top and funnel-shaped towards the bottom.When as sinkhole is formed solely through the process of solution, it is called as a solution sink.When several sink holes join together to form valley of sinks, they are called as blind valleys.

 

Caves

In the areas where there are alternative beds of rocks (non-soluble) with limestone or dolomite in between or in areas where limestone are dense, massive and occurring as thick beds, cave formation is prominent. Caves normally have an opening through which cave streams are discharged Caves having an opening at both the ends are called tunnels.

Stalactites and stalagmites

They are formed when the calcium carbonates dissolved in groundwater get deposited once the water evaporates.These structures are commonly found in limestone caves.Stalactites are calcium carbonate deposits hanging as icicles while Stalagmites are calcium carbonate deposits which rise up from the floor.When a stalactite and stalagmite happened to join together, it gives rise to pillars or columns of different diameters.

GLACIERS

Masses of ice moving as sheets over the land (continental glacier or piedmont glacier if a vast sheet of ice is spread over the plains at the foot of mountains) or as linear flows down the slopes of mountains in broad trough-like valleys (mountain and valley glaciers) are called glaciers.

EROSIONAL LANDFORMS

Cirque

Cirques are the most common of landforms in glaciated mountains. They are deep, long and wide troughs or basins with very steep concave to vertically dropping high walls at its head as well as sides. A lake of water can be seen quite often within the cirques after the glacier disappears. Such lakes are called cirque or tarn lakes.

Horns and Serrated Ridges

Horns form through head ward erosion of the cirque walls. If three or more radiating glaciers cut headward until their cirques meet, high, sharp pointed and steep sided peaks called horns form.

 

Glacial Valleys/Troughs

Glaciated valleys are trough-like and U-shaped with broad floors and relatively smooth, and steep sides. There may be lakes gouged out of rocky floor or formed by debris within the valleys. There can be hanging valleys at an elevation on one or both sides of the main glacial valley. Very deep glacial troughs filled with sea water and making up shorelines (in high latitudes) are called fjords/fiords.

 

Depositional landforms

 

Moraines

They are long ridges of deposits of glacial till. Terminal moraines are long ridges of debris deposited at the end (toe) of the glaciers. Lateral moraines form along the sides parallel to the glacial valleys. The lateral moraines may join a terminal moraine forming a horse-shoe shaped ridge. deposits varying greatly in thickness and in surface topography are called ground moraines.

 

Eskers

When glaciers melt in summer, the water flows on the surface of the ice or seeps down along the margins or even moves through holes in the ice. These waters accumulate beneath the glacier and flow like streams in a channel beneath the ice. Such streams flow over the ground (not in a valley cut in the ground) with ice forming its banks. Very coarse materials like boulders and blocks along with some minor fractions of rock debris carried into this stream settle in the valley of ice beneath the glacier and after the ice melts can be found as a sinuous ridge called esker.

Outwash Plains

The plains at the foot of the glacial mountains or beyond the limits of continental ice sheets are covered with glacio-fluvial deposits in the form of broad flat alluvial fans which may join to form outwash plains of gravel, silt, sand and clay.

Drumlins

Drumlins are smooth oval shaped ridge-like features composed mainly of glacial till with some masses of gravel and sand. The long axes of drumlins are parallel to the direction of ice movement. They may measure up to 1 km in length and 30 m or so in height.

 

Arid Landforms

Wind is one of the  dominant agents in hot deserts. The wind action creates a number of interesting erosional and depositional features in the deserts.

EROSIONAL LANDFORMS

Pediments and Pediplains

. Gently inclined rocky floors close to the mountains at their foot with or without a thin cover of debris, are called pediments. through parallel retreat of slopes, the pediments extend backwards at the expense of mountain front, and gradually, the mountain gets reduced leaving an inselberg which is a remnant of the mountain. That’s how the high relief in desert areas is reduced to low featureless plains called pediplains.

Playas

Plains are by far the most prominent landforms in the deserts. In times of sufficient water, this plain is covered up by a shallow water body. Such types of shallow lakes are called as playas where water is retained only for short duration due to evaporation and quite often the playas contain good deposition of salts.

. Deflation Hollows and Caves

Weathered mantle from over the rocks or bare soil, gets blown out by persistent movement of wind currents in one direction. This process may create shallow depressions called deflation hollows. Deflation also creates numerous small pits or cavities over rock surfaces. The rock faces suffer impact and abrasion of wind-borne sand and first shallow depressions called blow outs are created, and some of the blow outs become deeper and wider fit to be called caves.

Mushroom, Table and Pedestal Rocks

Many rock-outcrops in the deserts easily susceptible to wind deflation and abrasion are worn out quickly leaving some remnants of resistant rocks polished beautifully in the shape of mushroom with a slender stalk and a broad and rounded pear shaped cap above. Sometimes, the top surface is broad like a table top and quite often, the remnants stand out like pedestals.

Depositional Landforms

When the wind slows or begins to die down, depending upon sizes of grains and their critical velocities, the grains will begin to settle.

Sand Dunes

Dry hot deserts are good places for sand dune formation. Obstacles to initiate dune formation are equally important. There can be a great variety of dune forms Crescent shaped dunes called barchans with the points or wings directed away from wind .Parabolic dunes form when sandy surfaces are partially covered with vegetation. That means parabolic dunes are reversed barchans with wind direction being the same.

Seif is similar to barchan with a small difference. Seif has only one wing or point. Longitudinal dunes form when supply of sand is poor and wind direction is constant. They appear as long ridges of considerable length but low in height. Transverse dunes are aligned perpendicular to wind direction. These dunes form when the wind direction is constant and the source of sand is an elongated feature at right angles to the wind direction.

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.)

After coming to the power, Aurangzeb brought about many changes.

• 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.

 

 

 

The Liberation War of Bangladesh in 1971 was the culmination of a 25-year tumultuous relationship between East and West Pakistan. The British failed to keep a united India as riots started between the Hindus, Sikhs and Muslims in 1946. The riots were so widespread that on August 14, 1947 India was portioned into two separate states.

Thus partition of the Indian subcontinent in 1947 divided British India into two independent countries of India and Pakistan. Pakistan was composed of two wings–East and West Pakistan. The two wings were united emotionally, but the marriage of the two wings was artificial as they had little in common other than religion. Their speech, thought, food habits, dress, living and generally speaking, their respective way of life, were totally different.

These differences, in course of time, gave rise to a tumultuous relationship that failed to keep the two wings united. The flawed relationship ended in a brutal war in 1971. As such, it is imperative to learn the background of the Liberation War of Bangladesh in 1971.

Causes of War

Language Movement–1952

Bangladeshis had one language and were proud of their ancestry; their language and literature were older than Urdu, the national language of West Pakistan, used by minority. Yet Mohammad Ali Jinnah stated in a public speech in March 1948 that Urdu would remain the state language of Pakistan. This infuriated all the non-Urdu speaking people of East Pakistan. On February 21, 1952, students and other civilians came out in the streets in protest but the police cracked down on the unarmed civilians. For East Pakistan, the language movement was the first stepping stone to independence.

Provincial Elections–1954

The first provincial elections were held in East Pakistan in 1954. In this election, Suhrawardy’s newly organized Awami League (Peoples’ League) allied with Fazlul Huq’s Peasants’ and Workers’ Party and a coalition of other Bangladeshi-dominated parties to form the United Front. In this election, the people of East Pakistan voted unilaterally for the alliance. As a result, the United Front had the maximum number of seats. Nurul Amin’s Muslim League, the dominant party in West Pakistan, won just 10 seats in East Pakistan; and thus, the Urdu-speaking people in East Pakistan’s ability to dictate policy was essentially finished. Fazlul Huq also became the chief minister of East Pakistan. The fine showing of the United Front convinced the politicians, civil servants, and the military at the center that they had to constrain Bangladeshi nationalism.

Ayub Khan’s Declaration of Martial Law–1958

In 1957 and 1958 governments rose and fell in Dhaka as the result of both instability in the assembly alignments and of intervention by the central government.43 As a sequel to the uncertainty, the deputy speaker of the house was killed in a riot. In such a dilapidated condition, president Mirza abrogated the constitution and declared martial law. General Ayub Khan remained as the chief martial law administrator. In 1962 Ayub Khan promulgated the new constitution of Pakistan, primarily giving enormous power to the president. Unfortunately, nothing addressed the concerns of East Bengal; and as such, anger, resentment and Bengali nationalism continued to grow.

Awami League’s Six-Point Program–1966

Before the resignation of Ayub Khan, several events took place in the political spectrum. Among those, the Awami League’s Six-Point Program was viewed as a foundational document in Bangladesh’s struggle for independence. This was not an instant memorandum developed within a short time. Rather, it was an outcome of Bangladeshi grievances accumulated for a long time. The initiation of the Six-Point Program started as a sequel to several events. However, the election of 1965 played an important role in formulating the program

National Election–1970

As Yahya Khan received the Six-Point Program from the Awami League, he opined that he was not in a position to implement them. He reiterated his prime task was to hold a general election in 1970 and hand over power at that point. However, in the December 1970 elections, the Awami League won 160 of 162 seats from East Pakistan. Bhutto’s Pakistan Peoples’ Party was successful in the west, winning 81 of 83 seats. Yahya Khan opened talks with both the leaders but failed to reach a consensus, and thus failed to hand over the power to an elected government.

India’s Perspective

There is no doubt that the creation of an independent Bangladesh was in India’s interest for many reasons.

• Firstly, the Indo–Pakistan War in 1965 over Kashmir was one of the tipping points in this regard. India spent a huge amount of money to keep armed forces at a constant state of readiness along the border of her hostile neighbor. A warm relationship with an independent Bangladesh would reduce this big expenditure.
• Secondly, India also wanted to start trading with East Pakistan for mutual benefit. But due to several political deadlocks, it was not a foregone conclusion.
• Thirdly, Pakistani rulers created a problem for India by training and militarily equipping the Naga rebels of Assam (northeastern part of India), who claimed a portion of India to establish an independent Nagaland.
• Apart from these issues, millions of East Pakistanis had religious, cultural, and linguistic ties with India. West Pakistani rulers also demeaned the Hindus of East Pakistan; whereas India was a Hindu-dominated country.

For all these reasons and more, India preferred an independent Bangladesh as a tonic to all these problems. The Indian government expected that if Bangladesh became independent, it would cooperate with India in a much wider form.

Course of War

On March 25, 1971, Yahya Khan, Bhutto and other members left for West Pakistan without giving any message or warning to the Awami League leaders. The West Pakistani military launched its sudden attack on March 25, 1917 at 11 p.m.it used automatic rifles, automatic weapons, bayonets and tanks. Yahya Khan appointed General Tikka Khan as the overall commander, and he was given 48 hours to suppress Bangladeshi nationalist movement. Within 34 hours, approximately 10,000 unarmed civilians were killed.

Until November 21, 1971, mostly Bangladeshi regular forces along with the Mukti Bahini operated in different parts of the country. Besides, there were few naval and air assets utilized to complement the war effort. However, on November 21, 1971 all the forces–Bangladesh Army, Navy, Air Force as well as the Mukti Bahini–launched their joint offensive against Pakistani military.

Pakistan launched the war against India on December 3, 1971, the UN took a more vigorous approach to the problem. While Soviet Union was supporting India, the U.S. and Chine stood by Pakistan. On December 5, 1971 Moscow vetoed a U.S. resolution urging the Security Council to call upon India and Pakistan to carry out a cease fire and military withdrawal.

The Russians exercised another veto within 24 hours when on December 7, 1971, the General Assembly voted 104 against 11 to call upon India and Pakistan to cease fire immediately and withdraw their forces to respective territories.

While the UN was debating, the war on the ground was going in favor of India. In the meantime, U.S. dispatched a naval task forces led by the nuclear-powered carrier Enterprise from U.S. seventh fleet. By the time the naval task force was close to Chittagong port of East Pakistan, all Pakistani forces surrendered unconditionally. If the UN espoused cease fire would be in effect, Bangladeshis’ hope for independence was not to be materialized.

 

 

 

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.”

 

 

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.

 

National Income

The study of National Income is important because of the following reasons:

• To see the economic development of the country.
• To assess the developmental objectives.
• To know the contribution of the various sectors to National Income.

Internationally some countries are wealthy, some countries are not wealthy and some countries are in-between. Under such circumstances, it would be difficult to evaluate the performance of an economy. Performance of an economy is directly proportionate to the amount of goods and services produced in an economy. Measuring national income is also important to chalk out the future course of the economy. It also broadly indicates people’s standard of living.

Income can be measured by Gross National Product (GNP), Gross Domestic Product (GDP), Gross National Income (GNI), Net National Product (NNP) and Net National Income (NNI).

In India the Central Statistical Organization has been formulating national income.

However some economists have felt that GNP has a measure of national income has limitation, since they exclude poverty, literacy, public health, gender equity and other measures of human prosperity.

Instead they formulated other measures of welfare like Human Development Index (HDI).

 

NATIONAL INCOME:

The National income measures the flow of goods and services in an economy.

Note: The National income measured only on flow and not on stock.

 

The National income measures of net volume of goods and services produced in a country during a year. It also includes net earned foreign income. The National Income is counted without duplication.

The National income measures the productive power of an economy (flow).

The National wealth measures the stock of commodities held by the nationals of a country at a given point of time.

The National income estimates are in relation with the financial year.

In India the financial year begins on April 1 and ends on March 31.

 

BEFORE INDEPENDENCE

No specific attempts were made.The 1^st attempt was made by Dada Bhai Naoroji (Grand Old Man of India) in the   year 1868 in his book ‘Poverty and Un British Rule in India’.He estimated that the per capita annual income as Rs. 20 per annum.

Other estimators William Digby in the year 1899, Findlay Shirras in 1911, 1922     and in 1933, Shah and Khambatta in 1921, V K R V Rao during 1925-29 and 1931-32 and R C Desai during 1931-40.

The above people estimated the national income with the value of the output of the agriculture sector and then added a certain percentage as the income of the non-agriculture sector.The estimates suffered with serious limitations.

 

AFTER INDEPENDENCE:

In August 1949 the Government of India appointed the National Income Committee. Prof. P C Mahalanobis was appointed as the chairman of the National Income Committee.The other 2 members of the committee were Prof D. R Gadgil and Prof V K R V Rao.The main job of the committee was to compile estimates of National Income.The 1^st report was submitted in the year 1951.The final report was submitted in the year 1954.

This report is considered to be a landmark in the history of India as this is the first time that it provided a comprehensive data of National Income for the whole India.

The government established the CSO (Central Statistical Organization) for further estimation of the National income.The CSO regularly publishes the national income.

 

CONCEPT (THEORY) OF THE NATIONAL INCOME:

GNP (Gross National Product)

GDP (Gross Domestic Product)

NNP (Net National Product)

NI (National Income)

PI (Personal Income)

DPI (Disposable Personal Income)

Now let us try to understand the meaning of each:

 

GDP (GROSS DOMESTIC PRODUCT):

 

The Gross Domestic Product is the money value of all the goods and services produced within the geographical boundaries of a country in a given period of time.

Note: the GDP is only within the country.

 

GNP (Gross National Product):

 

The GNP is the money value of the goods and services produced by a country in a given period of time Plus Total money value of goods and services produced by the nationals outside the country Minus Incomes received by the foreigners with in the country.

Note: The GNP is calculated on the basis of market prices of produced goods, it also includes indirect taxes and subsidies if any.

The GNP is equal to GDP if the income earned and received by the citizens of a country within the boundaries of foreign countries is equal to the income received by the foreigners within the country.

 

NNP (NET NATIONAL PRODUCT):

This is GNP minus depreciation.

NNP = GNP – Depreciation

Note: Depreciation is the consumption of capital stock

 

NI (NATIONAL INCOME):

The National income is also called Net National Product at factor cost. Hence,

NI = NNP minus (total indirect taxes + Subsidies)

Note: Both indirect taxes and subsidies are deducted from the NNP.

 

PI (PERSONAL INCOME):

This is actual income obtained by the people after deducting various taxes.

PI = National Income – (Corporate taxes + payments made for social security) +Government transfer payments+Business transfer payments+Net interest paid by the government.

 

DPI (Disposable personal Income):

This is the Personal income minus direct taxes.

DPI = PI – Direct taxes.

 

HOW THE NATIONAL INCOME IS MEASURED?

 

There a 3 methods to calculate the National income.These methods are given by Simon Kuznets.

• PM (Product Method) or Product service method.
• IM (Income Method)
• CM (Consumption Method) or expenditure method.

In India the combination of Product method and Income methods is used for calculating the National Income.

 

PRODUCT METHOD:

NI = GDP  – income earned in foreign countries – Depreciation.

In the Product method the GDP is taken into consideration.Net income earned in foreign countries is deducted from the GDP.From this the depreciation is subtracted.

 

INCOME METHOD:

In this method the National Income is calculated by

National Income = Total Rent Plus (+) Total wages Plus (+) Total Interest Plus (+) Total Profit.

The total net income of the people working in different sectors and commercial sectors are taken into consideration.

 

Consumption Method:

This method is not generally used for calculating the National income.According to this method

• National Income =Total Consumption Plus Total Savings

 

MISCELLANEOUS:

 

• The per capita income in India is calculated by CSO (Central Statistical Organization).

 

 

• According the statistics released by the CSO in 2015, the per capita income in the country reached Rs. 88538/- per annum . This is according to the data on current prices.
• The PMEAC (Prime Minister’s Economic Advisory Council) in the ‘Economic Outlook’ released on August 1, 2011 lowered the economic growth rate projection from 9 percent to 8.2 percent.The PMEAC also reduced the manufacturing sector growth rate from 9 percent to 7 percent.
• The CSO has included the contributions of all the 3 sectors (Primary, secondary and tertiary) in estimating the National income.

 

Difficulty in measuring National Income

There are many difficulties in measuring national income of a country accurately. The difficulties involved in national income accounting are both conceptual and statical in nature. Some of these difficulties involved in the measurement of national income are discussed below:

Non Monetary Transactions

The first problem in National Income accounting relates to the treatment of non-monetary transactions such as the services of housewives to the members of the families. For example, if a man employees a maid servant for household work, payment to her will appear as a positive item in the national income. But, if the man were to marry to the maid servant, she would performing the same job as before but without any extra payments. In this case, the national income will decrease as her services performed remains the same as before.

Problem of Double Counting

Only final goods and services should be included in the national income accounting. But, it is very difficult to distinguish between final goods and intermediate goods and services. An intermediate goods and service used for final consumption. The difference between final goods and services and intermediate goods and services depends on the use of those goods and services so there are possibilities of double counting.

The Underground Economy

The underground economy consists of illegal and uncleared transactions where the goods and services are themselves illegal such as drugs, gambling, smuggling, and prostitution. Since, these incomes are not included in the national income, the national income seems to be less than the actual amount as they are not included in the accounting.

Petty Production

There are large numbers of petty producers and it is difficult to include their production in national income because they do not maintain any account.

Public Services 

Another problem is whether the public services like general administration, police, army services, should be included in national income or not. It is very difficult to evaluate such services.

Transfer Payments 

Individual get pension, unemployment allowance and interest on public loans, but these payments creates difficulty in the measurement of national income. These earnings are a part of individual income and they are also a part of government expenditures.

Capital Gains or Loss

When the market prices of capital assets change the owners make capital gains or loss such gains or losses are not included in national income.

Price Changes

National income is the money value of goods and services. Money value depends on market price, which often changes. The problem of changing prices is one of the major problems of national income accounting. Due to price rises the value of national income for particular year appends to increase even when the production is decreasing.

Wages and Salaries paid in Kind 

Additional payments made in kind may not be included in national income. But, the facilities given in kind are calculated as the supplements of wages and salaries on the income side.

Illiteracy and Ignorance

The main problem is whether to include the income generated within the country or even generated abroad in national income and which method should be used in the measurement of national income.

Besides these, the following points are also represents the difficulties in national income accounting:

• Second hand transactions;
• Environment damages;
• Calculation of depreciation;
• Inadequate and unreliable statistics; etc.

 

 

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.

Forests – Natural Vegetation of India:Types and distribution

types

• Climate, soil and topographyare the major factors that influence Natural Vegetation of a place.
• The main climatic factors arerainfall and temperature. The amount of annual rainfall has a great bearing on the type of vegetation.

Annual Rainfall	Type of Vegetation
200 cm or more	Evergreen Rain Forests
100 to 200 cm	Monsoon Deciduous Forests
50 to 100 cm	Drier Deciduous or Tropical Savanna
25 to 50 cm	Dry Thorny Scrub (Semi-arid)
Below 25 cm	Desert (Arid)

• Temperature is the major factor in Himalayas and other hilly regions with an elevation of more than 900 metres.
• As the temperature falls with altitude in the Himalayan region the vegetal cover changes with altitude fromtropical to sub-tropical, temperate and finally alpine.
• Soil is an equally determining factor in few regions.Mangrove forests, swamp forests are some of the examples where soil is the major factor.
• Topography is responsible for certain minor types e.g.alpine flora, tidal forests, etc..

Moist Tropical Forests

Tropical Wet Evergreen Forests or Rain Forests

Climatic Conditions

• Annual rainfall exceeds 250 cm
• The annual temperature is about 25°-27°C
• The average annual humidity exceeds 77 per cent and
• The dry season is distinctly short.

Characteristics

• Evergreen: Due to high heat and high humidity, the trees of these forests do not shed their leaves together.
• Mesosphytic:Plants adopted to neither too dry nor too wet type climate.

What are mesophytes? ·         Unlike hydrophytic plants, such as water lily or pondweed, that grow in saturated soil or water, or xerophytic plants, such as cactus, that grow in extremely dry soil, mesophytes are ordinary plants that exist between the two extremes. ·         Mesophytic environments are marked by average to hot temperatures and soil that is neither too dry nor too wet.

• Lofty: The trees often reach 45 – 60 metres in height.
• Thick Canopy: From the air, the tropical rain forest appears like a thick canopy of foliage, broken only where it is crossed by large rivers or cleared for cultivation.
• All plants struggle upwards (mostephiphytes) for sunlight resulting in a peculiar layer arrangement. The entire morphology looks like a green carpet when viewed from above.

• Less undergrowth: The sun light cannot reach the ground due to thick canopy. The undergrowth is formed mainly of bamboos, ferns, climbers, orchids, etc.

Distribution

• Western side of the Western Ghats (500 to 1370 metres above sea level).

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 devoted 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

 

 

Rainfall: With an average annual rainfall of 1,170 mm, India is one of the wettest countries in the world. At one extreme are areas like Cherrapunji, in the northeast, which is drenched each year with 11,000 mm of rainfall, and at the other extreme are places like Jaisalmer, in the west, which receives barely 200 mm of annual rainfall. Though the average rainfall is adequate, nearly three-quarters of the rain pours down in less than 120 days, from June to September.

Groundwater: India’s groundwater resources are almost ten times its annual rainfall. According to the Central Groundwater Board of the Government of India, the country has an annual exploitable groundwater potential of 26.5 million hectare-meters. Nearly 85% of currently exploited groundwater is used only for irrigation. Groundwater accounts for as much as 70-80% of the value of farm produce attributable to irrigation. Besides, groundwater is now the source of four-fifths of the domestic water supply in rural areas, and around half that of urban and industrial areas. However, according to the International Irrigation Management Institute (IIMI), the water table almost everywhere in India is falling at between one to three meters every year. Furthermore, the IIMI estimates that India is using its underground water resources atleast twice as fast they are being replenished. Already, excessive ground water mining has caused land subsidence in several regions of Central Uttar Pradesh.

Surface water: There are 14 major, 44 medium and 55 minor river basins in the country. The major river basins constitute about 83-84% of the total drainage area. This, along with the medium river basins, accounts for 91% of the country’s total drainage. India has the largest irrigation infrastructure in the world, but the irrigation efficiencies are low, at around 35%.

Utilization of Water in India

Domestic use

Community water supply is the most important requirement and it is about 5% of the total water use. About 7 km3 of surface water and 18 km3 of groundwater are being used for community water supply in urban and rural areas. Along with the increase in population, another important change from the point of view of water supply is higher rate of urbanization. According to the projections, the higher is the economic growth, the higher would be urbanization. It is expected that nearly 61% of the population will be living in urban areas by the year 2050 in high-growth scenario as against 48% in low growth scenario. Different organizations and individuals have given different norms for water supply in cities and rural areas. The figure adopted by the NCIWRD9 was 220 litre per capita per day (lpcd) for class I cities. For the cities other than class I, the norms are 165 for the year 2025 and 220 lpcd for the year 2050. For rural areas, 70 lpcd and 150 lpcd have been recommended for the years 2025 and 2050. Based on these norms and projection of population, it is estimated that by 2050, water requirements per year for domestic use will be 90 km3 for low demand scenario and 111 km3 for high demand scenario. It is expected that about 70% of urban water requirement and 30% of rural water requirement will be met by surface water sources and the remaining from groundwater.

Irrigation

The irrigated area in the country was only 22.6 million hectare (Mha) in 1950–51. Since the food production was much below the requirement of the country, due attention was paid for expansion of irrigation. The ultimate irrigation potential of India has been estimated as 140 Mha. Out of this, 76 Mha would come from surface water and 64 Mha from groundwater sources. The quantum of water used for irrigation by the last century was of the order of 300 km3 of surface water and 128 km3 of groundwater, total 428 km3 . The estimates indicate that by the year 2025, the water requirement for irrigation would be 561 km3 for low-demand scenario and 611 km3 for high-demand scenario. These requirements are likely to further increase to 628 km3 for low-demand scenario and 807 km3 for high-demand scenario by 2050.

Hydroelectric power

The hydropower potential of India has been estimated at 84,044 MW at 60% load factor. At the time of independence, the installed capacity of hydropower projects was 508 MW. By the end of 1998, the installed hydropower capacity was about 22,000 MW. The status of hydropower development in major basins is highly uneven. According to an estimate, India has plans to develop 60,000 MW additional hydropower by the twelfth five-year plan. It includes 14,393 MW during the tenth five-year plan (2002–2007); 20,000 MW during eleventh (2007–2012) and 26,000 MW during the twelfth (2012–2017) five-year plans. A potential of the order of 10,000 MW is available for development of small hydropower projects in the Himalayan and sub-Himalayan regions of the country. Therefore, it is not only desirable but also a pressing need of time to draw a master plan for development of small, medium and large hydro-schemes for power generation.

Industrial

Water requirement Rough estimates indicate that the present water use in the industrial sector is of the order of 15 km3 . The water use by thermal and nuclear power plants with installed capacities of 40,000 MW and 1500 MW (1990 figures) respectively, is estimated to be about 19 km3 . In view of shortage of water, the industries are expected to switch over to waterefficient technologies. If the present rate of water use continues the water requirement for industries in 2050 would be 103 km3 ; this is likely to be nearly 81 km3 if watersaving technologies are adopted on a large scale.

Scarcity of Water

The highly variable nature of the climate makes groundwater the most popular alternative for irrigation and domestic water use across India and accounts for over 400 km3 of the annual utilizable resource in the country. This dependence on groundwater resources is particularly critical where dry season surface water levels are low or where wet season flows are too disruptive to be easily tapped. In addition to being accessible, groundwater quality is generally excellent in most areas and presents a relatively safe source of drinking water for Indians in rural and urban centers.

Agriculture remains central to the Indian economy and it therefore receives a greater share of the annual water allocation. According to the World Resources Institute (2000), 92% of India’s utilizable water is devoted to this sector, mostly in the form of irrigation. Groundwater alone accounts for 39% of the water used in agriculture and surface water use often comes at the expense of other sectors such as the industrial and domestic supply.7 Demand from the domestic sector has remained low and accounts for only 5% of the annual freshwater withdrawals in India8 .

The demand from domestic sector over the next twenty years will increase from 25 billion m3 to 52 billion m3. However, this increase in the demand from the domestic sector will not be as much as that from other sectors over the next several years.7 Currently, only 85% of the urban and 79% of the rural population has access to safe drinking water and fewer still have access to adequate sanitation facilities. Recognizing that the growing demand for water in agriculture and industries sets a pattern of water scarcity even in areas where there is sufficient water for domestic purpose, the national water policy has rightly prioritized drinking water over other uses.

However, in giving subsidies to the industrial and agriculture sectors where the water consumption is highest and allowing these sectors to use more water at negligible prices, the government has effectively contradicted its own water policy. This has resulted in mining of ground water leading to a rapidly falling water table. For example, the bottling companies of Pepsi and Coca-cola in different parts of India pay very little towards water mining and have practiced unsustainable water mining in these areas to the detriment of villagers and small farmers in the area.

Most urban areas are serviced by a municipal water distribution system. Usually, the municipal water supply originates from local reservoirs or canals, but in some cases water may be imported through inter-basin transfer. Although the major cities in India enjoy access to central water supply systems, these schemes often do not adequately cover the entire urban population and are notoriously inefficient and unreliable. In rural areas, access to water is even more precarious. Over 80% of the rural domestic water comes from groundwater sources since it is more reliable in terms of water quantity and quality. Still, in areas where water is scarce, rural women must travel long distances to wells or streams to fetch water for their daily needs.

In the past several decades, industrial production has increased in India owing to an increasingly open economy and greater emphasis on industrial development and international trade. Water consumption for this sector has consequently risen and will continue growing at a rate of 4.2% per year. According to the World Bank, demand of water for industrial, energy production and other uses will rise from 67 billion m3 to 228 billion m3 by 2025.

The United Nations has warned that by 2025 two-thirds of the world will face severe water shortages if the current pattern of water consumption continues. Water-privatization has been sought as one of the solutions to address the looming crisis.

Water Management

In view of the existing status of water resources and increasing demands of water for meeting the requirements of the rapidly growing population of the country as well as the problems that are likely to arise in future, a holistic, wellplanned long-term strategy is needed for sustainable water resources management in India.

Ground Water Management

Groundwater management to protect the aquifers from overexploitation, an effective groundwater management policy oriented towards promotion of efficiency, equity and sustainability is required. Agricultural holdings in India are highly fragmented and the rural population density is large. The exploitation of groundwater resources should be regulated so as not to exceed the recharging possibilities, as well as to ensure social equity. The detrimental environmental consequences of over-exploitation of groundwater need to be effectively prevented by the Central and State Governments. Overexploitation of groundwater should be avoided, especially near the coasts to prevent ingress of seawater into freshwater aquifers .

Clearly, a joint management approach combining government administration with active people participation is a promising solution . In critically overexploited areas, bore-well drilling should be regulated till the water table attains the desired elevation. Artificial recharge measures need to be urgently implemented in these areas. Amongst the various recharge techniques, percolation tanks are least expensive in terms of initial construction costs. Many such tanks already exist but a vast majority of these structures have silted up. In such cases, cleaning of the bed of the tank will make them reusable. Promotion of participatory action in rehabilitating tanks for recharging would go a long way in augmenting groundwater supply. Due to declining water table, the cost of extraction of groundwater has been increasing over time and wells often go dry. This poses serious financial burden on farmers. Hence, special programmes need to be designed to support these farmers. Finally, the role of government will have to switch from that of a controller of groundwater development to that of a facilitator of equitable and sustainable development. Shah18 mentions that three large-scale responses to groundwater depletion in India have emerged in recent years in an uncoordinated manner, and each presents an element of what might be its coherent strategy of resources governance .

Watershed management

For an equitable and sustainable management of shared water resources, flexible, holistic approach of Integrated Water Resources Management (IWRM) is required, which can cater to hydrological variations in time and space and changes in socio-economic needs along with societal values. Watershed is the unit of management in IWRM, where surface water and groundwater are inextricably linked and related to land use and management.

Watershed management aims to establish a workable and efficient framework for the integrated use, regulation and development of land and water resources in a watershed for socio-economic growth. Local communities play a central role in the planning, implementation and funding of activities within participatory watershed development programmes. In these initiatives, people use their traditional knowledge, available resources, imagination and creativity to develop watershed and implement community-centered programme.

Currently, many programmes, campaigns and projects are underway in different parts of India to spread mass awareness and mobilize the general population in managing water resources. Some of these are being implemented by the Central/State Governments, while others have been taken up by various Non-Governmental Organizations (NGOs). For example, Hariyali (meaning ‘greenery’) is a watershed management project, launched by the Central Government, which aims at enabling the rural population to conserve water for drinking, irrigation, fisheries and afforestation as well as generate employment opportunities.

The project is being executed by the Gram Panchayats (village governing bodies) with people’s participation; the technical support is provided by the block (sub-district) administration. Another good example of water conservation efforts is the ‘Neeru-Meeru’ (Water and You) programme launched in May 2000 by the Government of Andhra Pradesh. During the last three years, an additional storage space of more than 18,000 lakh m 3 has been created by constructing various water-harvesting structures such as percolation tanks, dugout ponds, check dams, etc. through peoples’ participation.

Rainwater harvesting

Rainwater harvesting is the process to capture and store rainfall for its efficient utilization and conservation to control its runoff, evaporation and seepage. Some of the benefits of rainwater harvesting are:

• It increases water availability
• It checks the declining water table
• It is environmentally friendly
• It improves the quality of groundwater through dilution, mainly of fluoride, nitrate, and salinity, and
• It prevents soil erosion and flooding, especially in the urban areas.

Even in ancient days, people were familiar with the methods of conservation of rainwater and had practised them with success. Different methods of rainwater harvesting were developed to suit the geographical and meteorological conditions of the region in various parts of the country.

Traditional rainwater harvesting, which is still prevalent in rural areas, is done by using surface storage bodies like lakes, ponds, irrigation tanks, temple tanks, etc. For example, Kul (diversion channels) irrigation system which carries water from glaciers to villages is practised in the Spiti area of Himachal Pradesh. In the arid regions of Rajasthan, rainwater harvesting structures locally known as Kund (a covered underground tank), are constructed near the house or a village to tackle drinking water problem. In Meghalaya, Bamboo Rainwater Harvesting for tapping of stream and spring water through bamboo pipes to irrigate plantations is widely prevalent. The system is so perfected that about 18–20 litres of water entering the bamboo pipe system per minute is transported over several hundred meters.
