Environmental Impact Assessment (EIA)

Notification on Environmental Impact Assessment (EIA) of developmental projects 1994 under the provisions of Environment (Protection) Act, 1986 making EIA  mandatory for 29 categories of developmental projects. One more item was added to the list in January, 2000. environmental impact assessment statutory for 30 activities

Environment Impact Assessment Notification of 2006 has categorized the developmental projects  in two categories, i.e., Category A and Category B

‘Category A’ projects are appraised at national level by expert appraisal committee

India has constituted the State Level Environment Impact Assessment Authority (SEIAA) and State Level Expert Appraisal Committee (SEAC)  to decentralize the environmental clearance process

The objective of EIA is to foresee and address potential environmental problems/  concerns at an early stage of project planning and design.

The EIA notification establishes four stages for obtaining Environmental Clearance.

  1. Screening
  2. Scoping and consideration of alternatives Baseline data collection
  3. Impact prediction
  4. Assessment of alternatives, delineation of mitigation measures and environmental impact statement
  5. Public hearing
  6. Environment Management Plan Decision making
  7. Monitoring the clearance conditions

Screening- It is only for Categories B

Screening Criteria are based upon:

  • Scales of investment; •       Type of development; and, •      Location of development

B1 Categories project require Environmental Impact Assessment while B2 category projects are exempted from EIA.

State Level Expert Appraisal Committee determine about project categories

Struggles for Gurudwara Reform and Temple Entry

 

  • The Akali movement
  • The movement arose with the objective of freeing the Gurudwaras from the control of ignorant and corrupt priests (mahants).
  • Apart from the mahants, after the British annexation of Punjab in 1849, some control over the Gurudwaras was exercised by Government-nominated managers and custodians, who often collaborated with mahants.
  • The government gave full support to the mahants. It used them to preach loyalism to the Sikhs and to keep them away from the rising nationalist movement.
  • The agitation for the reform of Gurudwaras developed during 1920 when the reformers organized groups of volunteers known as jathas to compel the mahants and the government appointed managers to hand over control of the Gurudwaras to the local devotees.
  • Tens of Gurudwaras were liberated within an year.
  • To manage the control of Golden Temple and othe rGurudwaras the Shiromani Gurudwara Prabandhak Committee was formed in November 1920.
  • Feeling the need to give the reform movement a structure, the Shiromani Akali Dal was established in December 1920.
  • The SGPC and Akali Dal accepted complete non-violence as their creed.
  • There was a clash between the mahant and the Akalis over surrendering the gurudwara at Nanakana. This led to killing of about 100 akalis.
  • The Nankana tragedy led to the involvement of Sikhs on a large scale in the national movement.
  • Keys Affair: In October 1921, the government refused to surrender the possession fo the keys of the Toshakhana of the golden temple of the Akalis. This led to protests. Leaders like Baba Kharak Singh and Master Tara Singh were arrested. Later, the government surrendered the keys to keep the Sikhs from revolting.
  • Guru ka Bagh gurudwara in Ghokewala was under dispute as the mahant there claimed that the land attached to it was his personal possession. When few akalis cut down a tree on that land they were arrested on the complain of the mahant. Seeing this thousands of akalis came and started cutting down the trees. About 4000 akalis were arrested. Later, the government didn’t arrest but started beating them up severly. But the alakis kept turning up. Ultimately the government had to surrender.
  • The akali movement made a huge contribution to the national awakening of Punjab.
  • However, the movement encouraged a certain religiosity which would be later utilized by communalism.
  • In 1923, the Congress decided to take active steps towards the eradication of untouchability.
  • The basic strategy it adopted was to educate and mobilize opinion among caste hindus.
  • Immediately after the Kakinada session, the Kerala Provincial Congress Committee (KPCC) took up the eradication of untouchability as an urgent issue.
  • KPCC adeiced to organize an procession on the temple roads in Vaikom, a village in Travancore, on 30 March 1924.
  • During the processions, the satyagrahis were arrested and sentenced to imprisonment.
  • On the death of Maharaja in August 1924, the Maharani released the Satyagrahis.
  • Gandhiji visited Kerala to discuss the opening of temple with Maharani. A compromise was reached whereby all roads except for the ones in the Sankethan of the temple were opened to the harijans.
  • In his Kerala tour, Gandhi didn’t visit a single temple because avarnas were kept out of them.
  • The weakness of the anti-caste movement was that through it aroused people against untouchability it lacked a strategy of ending the caste system itself.

Mughal Empire

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 , 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 (3rd 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.

 

 

Space Technology- Indian space programs.

 

Application of Satellites for different purposes

 

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

Indian Space Program:

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

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

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

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

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

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

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

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

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

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

 

Application of satellites for different purposes:

Satellites based on application can be categorized as follows:

Earth Observation satellite->

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

Communication satellite->

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

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

 

satellite->

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

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

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

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

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

Standard Positioning Service (SPS)

Restricted Service (RS)

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

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

 

Experimental satellite->

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

 

Small satellite->

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

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

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

 

Student/Academic satellite->

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

Sikkim : Trade and Commerce

Sikkim : Trade and Commerce

Sikkim is one of the fastest growing states in India. The state has favorable agro-climatic conditions, which support agriculture, horticulture and forestry. As per the state budget 2016-17, Sikkim got certified as first fully organic state in India by the Central Ministry of Agriculture and Farmers’ Welfare as well as other recognized agencies of the country.

Between 2004-05 and 2015-16, Gross State Domestic Product (GSDP) expanded at a compound annual growth rate (CAGR) of 19.44 per cent to US$ 2.75 billion whereas the Net State Domestic Product (NSDP) expanded at a CAGR of 19.11 per cent to US$ 2.33 billion.

The State Government has achieved remarkable progress in the core areas of agriculture, health, education and development in infrastructure. Today, Sikkim is the most talked-about state in the Country.

Sikkim has evolved as a progressive State with marked improvements in socio-economic indicators, despite facing the disadvantages of inadequate connectivity, high cost of infrastructure building and maintenance, difficulty in delivering services to dispersed populations in hilly areas.

People of Sikkim engage in different economic activities, prominent among which are Tourism, Industries, horticulture & agriculture etc. giving rise to a definite occupational structure. Major contributions to the economy are provided by sectors like Agriculture, Horticulture, Forest, Mining, Industries, Power, Tourism, Aqua Culture and  Livestock etc.

Agricultural economy

The state’s economy is largely agrarian, based on the terraced farming of rice and the cultivation of crops such as maize, millet, wheat, oil seeds, pulses, spices, cereals barley, oranges, tea and cardamom.

Agriculture is vital to the progress of Sikkim as more than 64% of the population depends on it for their livelihoods. The Sikkim AGRISNET is an internet-based agriculture information centre to promote scientific agricultural methods and convert research into practice in the agricultural sector. Sikkim has a suitable climate for agricultural and horticultural products. It supports multiple crops; viz., rice, wheat, maize, millet, barley, urad, pea, soya bean, mustard and large cardamom. The surveyed arable land in Sikkim is 109,000 ha, of which only 9.5% is used, this provides a vast untapped potential for development. The state government is also laying emphasis on improving organic farming in the state.

Agriculture is the major economic activity and is practiced on terraced field that has been laboriously created from steep hillsides. There are in all 689 enterprises that have been identified, which are mostly concentrated in rural areas.

Sikkim is the largest producer of cardamom and also boasts to utilize largest area for its cultivation. Tea is exported to USSR & Germany. A coffee plantation has also been started at Majitar.

The  economy broadly depends on the agriculture which provides livelihood to the majority of population in the state. However, it’s progress remained limited due to difficult topography and other natural barriers. As a result all head sectors related to agriculture emerged, government is doing its best to improve the situation.

Horticulture

Horticulture also contributes to the economy of  Sikkim. Large Cardamom, ginger and turmeric are the principal crops while Mandarin orange, guava, mango, banana and so on are the principal fruits grown in the state. The department of Horticulture is deeply involved in motivating and providing technical guidance to local farmers. Sikkim is also a paradise for flowers. Gladioli, anthuriums, lilliums, primulas, rhododendrons, orchids as well as many other floral species thrive here. The state is home to an amazing 450 species of exotic orchids alone. There is immense potential for developing floriculture on a commercial basis here, and the department of Horticulture is making concerted efforts to turn this sector into an export-oriented industry.

Forest

Sikkim has rich bio diversity and thus provides economic activities. The total land area managed by and under administrative control of Forest Department is above 80% of the total geographical area of the state. The composition ranges from tropical Dry Deciduous Forests with Sal and its associates in the valleys of Teesta and Rangit to the Alpine Scrub and Grasslands in high altitudes. During the two last decades Forest Department has laid emphasis on development of fodder and fuel wood in the agriculture fallow lands of the villagers giving priority to plantation of broom grass for fodder and for economic up liftment of the villagers.

Aqua Culture

Pisiculture is an important area of economic activity particularly in the context of enabling the rural people. The state’s natural resources endowments with an extensive network of freshwater rivers, lakes and streams offers conditions which are conducive for development of inland fisheries where a variety of carps and trout’s can thrive. With a view to exploit these natural resources endowments.

Sericulture

Mulberry, muga, eri and  oak-tussar are cultivated in Sikkim. The Sericulture Directorate is responsible for development of sericulture in Sikkim. The sericulture potentiality of Sikkim state has been explored jointly by the State Department and Central Silk Board, through launching a flagship programme titled Catalytic Development Programme. Over the years with consorted efforts from the both ends (state and central governments), considerable success have been achieved by the state sericulture industry in generating employment. Raw silk production in the state increased from 0.20 metric tonnes in 2013-14 to 6.0 metric tonnes in 2015-16.

Livestock

Animal Husbandry provides an additional source of income to the people. Animal husbandry form an extremely important element in the effort to bring about substantial improvements in living standards. The overall area available for agriculture operations is limited to about 15% of the geographical area of the state and with the increasing population, per capita land availability has been consistently declining, it is therefore, essential, that supplementary sources of income should be developed in order to provide not only the much needed support to the rural families but also to make available in increasing quantity, protein rich food items such as milk, egg, and meat. Adequate number of livestock like cattle, buffaloes, pigs, sheep’s, goats, yaks and few other are reared in Sikkim. Yaks are reared in north eastern ranges bordering Tibet, Bhutan and western region bordering Nepal.

Industries and Mining

The Commerce and Industries Department of Sikkim is involved in promoting trade and industry in Sikkim. The Sikkim Industrial Development & Investment Corporation Limited (SIDICO) is the state-level institution engaged in promoting, financing and developing the tiny and small scale industries (SSI) sector in the state.

Brewing, distilling, tanning and watch making are the main industries located in the southern regions of Sikkim. A small mining industry exists in the state, extracting minerals such as copper, dolomite, talc, graphite, quartzite, coal, zinc and lead. Sikkim has identified Rangpo-Gangtok, Melli-Jorethang, Jorethang-Rishi and Ranipool-Gangtok as industrial corridors with provision for giving land to investors on a lease basis.

The units that are engaged in the manufacturing sector are mainly dealing with pharmaceuticals, chemicals, liquors, foam mattresses, food products, iron rods, etc. Sikkim has identified agro-based industries, horticulture and floriculture, minor forest-based industries, animal husbandry and dairy products, tourism-related industries, IT including knowledge-based industries, precision oriented high value-low volume products, hydro-power, tea, education and hospitality as thrust sectors. The Information Technology (IT) Department, Government of Sikkim is in the process of setting up a state-of-the-art IT Park and National Institute of Electronics and Information Technology (NIELIT) at Pakyong.

Pharmaceuticals

Pharmaceutical is an emerging industry in Sikkim due to tax incentives offered by the state government as well as low manufacturing and labor costs. Sikkim is home to 14 major pharma companies, which have significant investments in the state. The North-East Industrial and Investment Promotion Policy, 2007 and the pollution free atmosphere are highly beneficial for pharma investments in Sikkim. Some of the policy incentives are: 100% excise duty exemption on finished products. 100% income tax exemption. 30% capital investment subsidy on investments in plant and machinery.

The policy of framework in regard to industrialization in Sikkim has to be formulated keeping in mind the particular factors endowments that the state has the limitations in regard to resources, particularly, minerals and industrial raw materials as well as man power. The state is not so rich in mineral resources and apart from the deposits of copper, lead and zinc, no other viable and exploitable mineral deposits have so far been discovered. While on the other hand the state enjoys a tranquil climate, a dust free atmosphere and peaceful industrial entrepreneurial talent, has also to be taken note of. In regard to industrial development, a number of small and medium units have been promoted in the state. For example, The Sikkim Time Corporation (SITCO) and Government Institute of Handicraft and Handlooms.

Mining

The state of Sikkim is endowed with rich geological resources. The department of mines and geology has been responsible for exploration and establishment of mineral resources, with the object of developing commercially exploitable mineral resources. Moderate to fair amount of success has been achieved during the investigation carried out by different agencies in certain sectors namely dolomite, coal, quartzite, graphite, lime stone, silliminite, talc, mineral water, thermal springs, building stone and materials for porcelain.

Tourism

Tourism provides the main thrust to the economy. With the tranquil climate, the natural beauty and the fine cultural heritage of Sikkim, the growth of tourism has immense possibilities. There are large number of places of tourist attraction particularly the snow clad mountains, the lakes and unspoiled forest areas and valleys of flowers. The advantage of having very fine monasteries in Sikkim can also be taken to attract Buddhist tourists from countries like Japan and the South Eastern countries.

Sikkim was the first to promote the concept of eco-tourism, village tourism and home stay tourism in the country. This essential concept promoting man-nature affinity has been recognized as a new model of tourism. Today, Sikkim is already on the national and international tourism map.

Sikkim has been featured and ranked 17th in the New York Times “52 best places to go in 2017”. Similarly, Sikkim has also been featured as the best destination to visit in the world in 2014.

The Year 2017 has been declared as the Year of Sustainable Tourism for Development, an area of development in which Sikkim has already made considerable strides with eco-friendly tourism and the development of innovative initiatives such as Chaar Dham and Tathagatha Tsal. Additionally, Gangtok City has been recognized as the safest tourist destination in the country.

Keeping nature at the backdrop, the State Government proposes to promote tourism mainly through nature based tourism. Few activities which are proposed include, Rock Art Sculpture, Folk Healing Center and Yoga Sthan. In the niche Tourism Sector, facilities such as golf courses, water sports etc, are being proposed.

A priority has been given to create mega projects, one example of which is the Sky Walk at Bhaleydunga. The Ropeway to Bhaleydunga, currently under progress is expected to be completed in 2 years time. Today, Sikkim having been featured in leading International Journals and magazines, has become one of the most sought after destinations and caters to all types of tourists. Film tourism is also catching up fast with the support of the government, as many recent film shoots by popular Bollywood artistes in the state takes place.

Through sustainable forest management practices and massive afforestation drives, about 72.60 lakh saplings have been planted till date under the State Government’s flagship programmes such as Smritivan, State Green Mission, Ten Minutes to Earth and Paryavaran Mahotsav. The forest and tree cover of the State has increased by about 4% over the last two decades from 43.95% to 47.80%. The State Government has also banned the use and sale of disposable Styrofoam products, prohibited the burning of tyres, agricultural waste, use of packaged drinking water bottles, bursting of crackers in Sikkim which are first such prohibitions imposed in the entire world.

The declaration of the Khangchendzonga National Park as UNESCO’s World Heritage Site on 17th July, 2016 at Istanbul, Turkey, is a testimony to the tireless efforts of the government. The Khangchendzonga National Park has also been declared as one of the 100 top Green Destinations of the world for the second consecutive time. In addition to this, the State Government is also proposing to develop a world class Biodiversity Park and Ecotourism Centre at Tendong, South Sikkim.

The State Government has now prioritized the construction of a Ropeway from Pelling to Sangacholing Monastery in West Sikkim connecting the landmark statue of Lord Chenrezig, that is near completion, to Pelling. This project along with the Statue of Lord Chenrezig would be a great value addition to tourism in boosting tourism footfall in the State. The boost in the tourist footfall is very encouraging as Sikkim hosted over 8 lakhs tourists in 2016 alone.

Major initiatives taken by the government to promote economy of the state

The state government launched Sikkim AGRISNET, an internet-based agriculture information centre, to promote scientific agricultural methods and convert research into practice in the agricultural sector.

The Government of Sikkim has placed information technology high on its agenda. The budget allocation for information and broadcasting is expected to be US$ 0.96 million during 2015-16.

Pharmaceutical is an emerging industry in Sikkim due to tax incentives offered by the state government as well as low manufacturing and labour costs. Sikkim is home to 14 major pharma companies, which have significant investments in the state. These include Cipla, Sun Pharma, ZydusCadila, Alembic, IPCA, Alkem Lab, Intas Pharma, Torrent Pharma and Unichem.

The Sikkim government has announced a technical collaboration with floriculturists from the Netherlands and Thailand to develop the state’s potential in floriculture and market cut flowers from the state globally.

The Department of Information Technology, Government of Sikkim is in the process of setting up an IT park and National Institute of Electronics and Information Technology (NIELIT) at Pakyong. The IT Park will have state-of-the-art facilities that will offer a plug and play environment and cater to the specific needs of the information technology and business process outsourcing (BPO) segments.

In order to give a boost to handloom and handicrafts sector, the Government of Sikkim has been making several efforts, which include providing training to upgrade the quality and designs of the products; bringing expertise and professionals for their marketing and supply, etc.

The Sikkim Government plans to set up Tea Development Corporation of Sikkim, which would be the nodal agency for developing the tea Industry in Sikkim. It would work to expand the Temi tea estates in the state and acquire new gardens either wholly or partially owned by the government.

The Sikkim Manipal University (SMU), a partnership between the Government of Sikkim and Manipal Education and Medical Group (MEMG), provides technical, healthcare and science education. It is rated as one of the top universities in the country.

The State Government is very concerned with the youth populace and therefore, has laid special emphasis to skill the youth and to make them employable and self-dependent so that they can lead a life of self-respect and confidence. A separate Department of Skill Development & Entrepreneurship and Capacity Building therefore has been setup with its network of the State Institute of Capacity Building, Livelihood schools, Industrial Training Institutes, Kaushal Kendras and Incubation Centres for skilling the youth. These initiatives aim at creating opportunities for self-employment, for industrial wage employment, and community based employment as Social Entrepreneurs.

Till December 2016, a total number of 10,151 trainees have been trained in sectors such as Beauty & Wellness, Tourism & Hospitality, Apparel, Homestay, Driver cum Tour Guide, Primary Teacher Training etc. An Atal incubation centre has been approved by the Ministry of Skill Development in Assam Lingzey. Two more incubation projects for the distillation of lemon grass oil has been set up in Kerabari, South Sikkim, and Timberbong, West Sikkim, under the Rastriya Krishi Vikas Yojana.

BIOTIC INTERACTION

 

The interaction between the organisms is fundamental for its survival and functioning of ecosystem as a whole.

Type of Biotic Interaction

  1. Mutualism:

both species benefit.

Example: in pollination mutualisms, the pollinator gets food (pollen, nectar), and the plant has its pollen transferred to other flowers for cross-fertilization (reproduction).

 

  1. Commensalism:

one species benefits, the other is unaffected.

Example: cow dung provides food and shelter to dung beetles. The beetles have no effect on the cows.

 

  1. Competition:

both species are harmed by the interaction.

Example: if two species eat the same food, and there isn’t enough for both, both may have access to less food than they would if alone. They both suffer a shortage of food

 

  1. Predation and parasitism:

one species benefits, the other is harmed.

Example : predation—one fish kills and eats ..parasitism: tick gains benefit by sucking blood; host is harmed by losing blood.

 

  1. Amensalism :

One species is harmed, the other is unaffected.

Example: A large tree shades a small plant, retarding the growth of the small plant. The small plant has no effect on the large tree.

 

  1. Neutralism :

There is no net benefit or harm to either species. Perhaps in some interspecific interactions, the costs and benefits experienced by each partner are exactly the same so that they sum to zero

GRASSLAND ECOSYTEM

 

found where rainfall is about 25-75 cm per year, not enough to support a forest, but more than that of a true desert.

vegetation formations that are generally found in temperate climates.

In India, they are found mainly in the high Himalayas. The rest of India’s grasslands are mainly composed of steppes and savannas.

Steppe formations occupy large areas of sandy and saline soil; in western Rajasthan, where the climate is semi-arid,

The major difference between steppes and savannas is that all the forage in the steppe is  provided only during the brief wet season whereas in the savannas forage is largely from grasses that not only grow during the wet season but also from the  smaller amount of regrowth in the dry season.

 

Types of Grasslands

  1. semi-arid zone (The Sehima-dichanthium type)

It covers the northern portion of Gujarat, Rajasthan (excluding Aravallis), western Uttar Pradesh, Delhi and Punjab.

The topography is broken up by hill spurs and sand dunes.

senegal, Calotropis gigantia, Cassia auriculata, Prosopis cineraria, Salvadora oloides and zizyphus Nummularia which make the savanna rangeland look like scrub.

  1. dry sub humid zone (The Dichanthium- cenchrus-lasitrrus type)

It covers the whole of peninsular India (except Nilgiri).

The thorny bushes are Acacia catechu, Mimosa, Zizyphus (ber) and sometimes fleshy Euphorbia, along with low trees of Anogeissus latifolia, Soymida febrifuga and other deciduous species.

Sehima (grass)is more prevalent on gravel and the cover maybe 27%. Dichanthium (grass) flourishes on level soils and may cover 80% of the ground.

3)  moist subhumid zone(The Phragmities- sacchrum-imperata type)

It covers the Ganga alluvial plain in Northern India.

The topography is level, low lying and ill-drained.

Bothriochloa pertusa, Cypodon dactylon and     Dichanthium annulatum are found in transition zones.

The common trees and shrubs are Acacia arabica, hogeissus, latifolia, Butea monosperma,

Phoenic sylvestris and Zizyphus nummularia.

Some of these are replaced by Borassus sp in the palm savannas especially near Sunderbans.

4) The Themeda – Arundinella type

This extends to the humid montane regions and moist sub-humid axeas of Assam, Manipur,West Bengal, Uttar Pradesh, Punjab, Himachal Pradesh and. Jammu and Kashmir.

The savanna is derived from the humid forests on account of shifting cultivation and sheep grazing.

Role of fire

fire plays, an important role in the management  of grasslands.

Under moist conditions fire favours grass over trees, whereas in dry conditions fire is often necessary to maintain grasslands against the invasion of desert shrubs.

Burning increases the forage yields, e.g. Cynodon daotylon
