Hindu Kush-Himalayan Region

 

The geographic qualifier 'Hindu Kush-Himalayan' is not very precise. ICIMOD's target area includes the Karakorum, the Pamir, and other neighbouring ranges. The Hindu Kush-Himalayan (HKH) region extends 3,500 km over all or part of eight countries from Afghanistan in the west to Myanmar in the east. It is the source of ten large Asian river systems -– the Amu Darya, Indus, Ganges, Brahmaputra (Yarlungtsanpo), Irrawaddy, Salween (Nu), Mekong (Lancang), Yangtse (Jinsha), Yellow River (Huanghe), and Tarim (Dayan), - and provides water, ecosystem services, and the basis for livelihoods to a population of around 210.53 million people in the region. The basins of these rivers provide water to 1.3 billion people, a fifth of the world’s population.

The Himalayan range alone has the total snow and ice cover of 35,110 sq.km containing 3,735 cu.km of eternal snow and ice (Qin 2002). The total for the region is not yet calculated. Hills and mountains, particularly the Hindu Kush-Himalaya mountain system, have always constituted places where adaptation, mitigation, and resilience are hallmarks of the people and the landscape they inhabit. Since time immemorial, the people of the Himalaya have maintained a rich cultural identity, and have maintained food security and biogenetic diversity within the parameters of their own tradition.

Dams Over India

 

India got her independence in 1947. Since then, dams in India have been built across many perennial rivers. These dams are a part of the several multi-purpose projects launched by India to serve a variety of needs. In a multi-purpose project, a river forms a unit and a river valley is developed, by exploiting all the resources of the river.

Dams are built to harness the river water so that it can be utilised according to needs. A multipurpose project is launched often for storing water for irrigation purposes, generating hydro-electricity by utilising the water stored by the dams, preventing floods and facilitating afforestation in the catchment areas of the reservoirs. However, the dams also provide drinking water, using the canals for navigation in some areas and also facilitating pisciculture and recreational activities. The main multipurpose projects constituting the major Indian dams are the Hirakud Project in Orissa, the Bhakra Nangal in Punjab, the Damodar Valley Project in Bihar and Bengal, the Tungabhadra Project in Andhra Pradesh and Karnataka, the Rihand Project in Uttar Pradesh.

At independence, in 1947, there were fewer than 300 large dams in India and by the year 2000 the number had grown to over 4000, more than half of them built between 1971 and 1989. India is declared to be the third in the world in dam building, after US and China. While some of the Indian dams were built primarily for flood control, water supply, and hydroelectric power generation, the primary purpose of most Indian dams (96 percent) remains irrigation. In fact, large dam construction in India has been the main form of investment in irrigation undertaken by the Indian government. But, starting in the 1980s, public investment in large dams in India has been the subject of a sustained controversy that was epitomized by the Sardar Sarovar Project, based on the balance between the social, environmental, and economic costs of dams and their benefits.

Tungabhadra dam Most irrigation dams in India are embankment dams, meaning that they consist of a wall built across a river valley to impound water so as to form a reservoir upstream and a system of spillways and gates to bypass the wall so as to maintain normal river flow and convey water to a network of canals feeding irrigated regions downstream. The upstream areas that feed the dam and those submerged by its reservoir are called its "catchment" area, and the downstream areas fed by its irrigation canals and are known as the "command" area. The proponents of large dams focus on the aggregate productivity benefits, emphasizing the role of dams in enabling irrigation.

Owing to the construction of dams in India, between 1951 and 2000, India`s production of food grains increased fourfold, from 51 million tonnes to about 200 million tonnes. This not only obviated the importation of food grains, with attendant saving in foreign exchange, but left India with a marginal food grain surplus. The most optimistic estimates of these dams attribute 25 percent of the increase in food grain production to dam irrigated areas. But it is incorrect to attribute the entire production gains in dam-irrigated areas to dams. However, there are also certain disadvantages of dams in India. Large-scale impounding of water increases exposure to vector-borne diseases, such as malaria, schistosomiasis, filariasis, and river blindness. Although dams may also increase economic activity in the catchment area, such as tourism and fishing, these increase are either temporary or depend on the ability to learn new trades.

One specific determinant of dam construction in India, however, is geographic suitability. Dam location is strongly influenced by river gradient. A river flowing at a moderately positive gradient favors irrigation dams; higher water levels upstream facilitate water storage and diversion into irrigation canals. Consequently, within states, new dams tend to be built in those regions that have river flowing at a moderate incline. After one accounts for the impact of the overall higher altitude of the district and the availability of rivers, the gradient of the rivers is unlikely to have a direct impact on changes in agricultural productivity or other district-level outcomes before and after a state builds new dams. Therefore, it is advised to use the variation in dam construction induced by differences in river gradient across districts within Indian states to determine the impact of large dams.

Bhakra dam Large dam construction has been an important and expensive undertaking for the Indian government. While dams have enhanced agricultural productivity in India, there is no evidence that they have been very cost effective, and they have significantly adverse distributional implications. The case of large dams recommends strongly that distributional implications of public polices should be integral to any decision. Punjab, Haryana and Rajasthan have jointly launched the Bhakra-Nangal Project. It is the biggest multi-purpose project in India, started in1948 and completed in 1968. This project derives its name from the two dams Bhakra and Sutlej, built on a tributary of the Indus, the Sutlej. The Hirakud Dam Project is the first major multipurpose river valley project in India, after India was liberated from the British rule in 1947. Constructed across the river Mahanadi at about 15 Kms. upstream of Sambalpur town in Orissa the main dam, the Hirakud is 6 Kms from NH(National Highway) 6 and 8 kms from the Hirakud railway station.

The Rihand project is the most important multi-purpose project in Uttar Pradesh. The Rihand River flows across a narrow gorge in the Vindhyan ranges in the Mirzapur district of Uttar Pradesh. It may appear lazy and docile in the dry season but during the monsoons it is a very strong and vicious river. The Tungabhadra project is a joint venture of the states of Karnataka and Andhra Pradesh. The Tungabhadra dam , 2441 metres in length and 49.38 metres in height, is constructed on the Tungabhadra river at Mullapuram(in Bellary district) about 4.8 kilometres from Hospet. The Damodar Valley Corporation (DVC) handles the Damodar Valley Project. Launched on the river Damodar, this project benefits the states of West Bengal and Bihar. An important feature of this project is the 692 metres long and 11.6 metres high barrage constructed across the Damodar at Durgapur. The Right Bank canal and the Left Bank canal, originating from the barrage are used for irrigation and navigation respectively.

The dams of India have developed the internal navigation by which the pressure on the railways has relieved to some extent. Moreover, these dams have effectively controlled floods on rivers, thus preventing untold damage to the people of the nation.

Nagarjuna Sagar DamDams in Andhra Pradesh serve the purposes of irrigation, thermal power and drinking water to all the districts of the state. The colossal dams not only supply water for irrigation and are the source of hydro electricity but are also regarded as the popular tourist spots.Nagarjuna Sagar Dam, Srisailam Project, Srisailam Dam, Nizam Sagar Joorala project, Telugu Ganga, Nijam Sagar Reservoir and Osman Sagar are some of the prime dams in Andhra Pradesh, primarily serving irrigational purposes. The dams, barrages and projects are carried out in Andhra Pradesh particularly on rivers like Penner, Musi, Tungabhadra, Godavari and Krishna. The Shriram Sagar Reservoir, Dowleswaram Barrage, Inchampalli multi-purpose irrigation project, Dummaguden Dam are constructed across the Godavari River in Andhra Pradesh. Tatipudi Reservoir Project was constructed across River Gosthani in Vizianagaram District of Andhra Pradesh. Yellampalli project or the Sripada Sagar project stands on Godavari River in Karimnagar district of Andhra Pradesh.

The Ramagundam dam is a thermal project built in Andhra Pradesh. Singur Dam was constructed in Andhra Pradesh in 1989. Sunkesula Barrage is constructed on the Tungabhadra River in Andhra Pradesh. Nagarjuna Sagar Tail Pond Project is constructed at downstream of Nagarjuna Sagar Dam, across River Krishna in Andhra Pradesh. The Pulichintala Project is also build over the Krishna River at Pulichintala Village in Andhra Pradesh. Prakasam Barrage was build across the River Krishna in 1855. Lower Manair Reservoir is situated in the Indian state of Andhra Pradesh, since 1985. Gandipalem Reservoir and Somasila Dam are built on the River Penner in Andhra Pradesh. The Dindi Reservoir is constructed in Andhra Pradesh for the purpose of irrigational water. Himayat Sagar Reservoir is constructed across the Musi River in Andhra Pradesh.

The Nizam Sagar Dam is one of the major dams in Andhra Pradesh which is located at a distance of 144 kilometers to the northwest of Hyderabad. This reservoir was built on the River Manjira, which is a tributary of the Godavari River. The Nizam Sagar dam was erected in between the Banjapalle and the Achampet villages of the district of Nizamabad in the Indian state of Andhra Pradesh. The entire surrounding of the Nizam Sagar Dam is very much famous for its scenic beauty and which is why people visit this place to enjoy the natural environment of peace and tranquility. The most striking thing about it is that there is a motorable road of 14 ft in width over the dam measuring three kilometers long. The surroundings of the Nizam Sagar Dam is well-known as one of the major tourist destinations in Andhra Pradesh where one can avail budget as well as luxury accommodation close to the area. Neighboring the Nizam Sagar reservoir is the Jawahar Navodaya Vidyalay. Huge volume of water from this reservoir and also from the river is released to the twin cities of Secunderabad and Hyderabad. One will get to see a very beautiful garden next to the Nizam Sagar Dam. At the time of monsoon a large number of tourists from the nearby states of Maharashtra, Karnataka and several other districts of Karimnagar, Medak and Hyderabad and various other places visit the Nizam Sagar Dam area. There is also the availability of boating in the Nizam Sagar reservoir.

Somasila Dam in Andhra Pradesh stands on the Pennar River. This is also among the most prominent attractions for tourists in the state. The Somasila Dam is constructed over the river Pennar River in a small town by the name of Somasila in the district of Nellore in Andhra Pradesh. The place is famous for Somasila Water Project constructed across the River Penner and the Lord Shiva temple. The Lord Shiva temple is associated with a very old history and it is situated close to the dam. The Somasila Water Project was constructed during the period of the then Chief Minister of Andhra Pradesh, N.T. Rama Rao. This project has become very vital as far as agriculture in the state is concerned. It supplies water to several agricultural fields of different villages in Andhra Pradesh. One of the villages is Penna Baddevolu which is situated downstream of the River Penner.

Water of the K-C canal from the Rajolibanda dam was reopened as a vent in the Sunkesula barrage that mainly took care of the drinking water problem of the Mahabubnagar region in the state of Andhra Pradesh in India. A delegation of Telangana Rashtra Samithi (TRS) MLAs and senior leaders along with the support of the then Chief Minister Dr. Y.S. Rajasekhara Reddy implemented the government order for the construction of the Rajolibanda dam.

The idea of building Prakasam Barrage across River Krishna dates back to 1798. However, the construction planning was revised and redesigned by captain Buckle in 1839, and latter again in 1841 by Captain Best and Captain Lake. After the support of Major Cotton, the board of Directors of British East India Company approved the plan of Prakasam Barrage on 5th January 1850. The construction of Prakasam Barrage was started in 1852 and completed in 1855. Later the State Government builds a new regulator cum-round bridge that was named after Sri Tanguturi Prakasam, the first Chief Minister of Andhra Pradesh. The barrage started to work officially since 1957 and it helps irrigating over 12 lakhs of acres. The Prakasam Barrage provides a panoramic view of the river. The magnificent structure of this barrage extends to a distance of 1223.5 meters over the Krishna River. The Prakasam Barrage also acts as one of the major road bridges in Andhra Pradesh spanning over a beautiful lake. There are three canals which are linked to this barrage running through Vijayawada. The project of Prakasam Barrage was one of the first major irrigation projects of the southern parts of India which became completely successful in its mission. The richness in the field of agriculture for the state of Andhra Pradesh is due to the Prakasam Barrage since the barrage is irrigating a large patch of agricultural lands every year. Sightseeing is one of the major attractions at this place with the barrage offering a pleasant view along with the beaming lake. The pleasant breeze blowing all the time along with the calm waters make it a suitable destination for tourists in Vijayawada.

The Dindi Reservoir is constructed between the area of Brahminepalle and Dindi on Krishna River. The geographical condition of the region is flat with a very lesser number of canals and large areas of cultivated lands. Apart from the Dindi Reservoir, there are many more canals in the region. The Dindi Reservoir is situated in close proximity to the Nagarjuna Sagar Srisailam Tiger Reserve. Another Dam in the state is the Lower Manair Dam which is located at Karimnagar district in Andhra Pradesh. The construction work of the Lower Manair Dam was initiated in the year 1974 and the same was fully completed in the year 1985. During monsoon, water in the reservoir increases in large volumes.

Tatipudi Reservoir Project was built from the period 1963 to 1968. This project is constructed across the Gosthani River in the state of Andhra Pradesh. The Tatipudi Reservoir Project in Andhra Pradesh provides water for the irrigation of a total of 15,378 acres land in the Vizianagaram district. It also forms the major source of drinking water for the people of the city of Visakhapatnam. This Project uses 3.325 TMC of the water and the storage capacity of reservoir is about 3 TMC. The approximate price of the project was Rs.1.820 crores. The Srisailam Dam is situated across the River Krishna at Srisailam in the district of Kurnool. This is one of the major dam projects of the state of Andhra Pradesh. It is also one of the 12 largest hydroelectric projects in India. The Srisailam Dam is constructed in a deep gorge in the Nallamala hills and it is placed 300 meters above sea level. This dam is 512 meter in length and 240.79 meter in height. It is having twelve radial crest gates. The Srisailam Dam provides water for irrigation to about 800 Sq Kilometers of land in the districts of Kurnool and Cuddapah. This dam of Andhra Pradesh is the prominent source of water in the Rayalaseema region which is having shortage of water throughout the year. In order to go to the main dam the tourists need to take special permission from the concerned authority. The town of Srisailam is situated at a distance of about 232 kilometers to the south of the city of Hyderabad. There are several places of interest close to the Srisailam Dam like the Bhramaramba Mallikarjunaswamy temple situated on the hilly regions of Nallamala Forest. One can also find the Sikhareswara Swamy temple and the Sri Ganapathi temple which are in close proximity to this dam. The railway station close to this dam is Nandyal situated on the Guntur-Hubli broad gauge line. This railway station is at a distance of about 158 kilometers from the Srisailam Dam.

The Government of Andhra Pradesh has come up with a scheme for the construction of Joorala Project. The site of the project is located at a distance of about 10 kilometers from Kuravapur. The people living in the surrounding area of the project in Andhra Pradesh will be highly benefited by it. The Kurvapur Kshetra River is merging with water of the Joorala Project and the construction work of the Joorala Project is still under progress. Another dam in the state of Andhra Pradesh in India is the Singur Dam. The construction of the Singur dam was completed by the Government of India in the year 1989 in Andhra Pradesh. With the support of World Bank, the Sanitation project and Hyderabad Water Supply was in charge of the dam and its smooth functioning. The huge reservoir constructed by the Singur Dam forms the primary source of electric power, water for irrigation and drinking water in the nearby areas. Due to the construction work of the Singur Dam, a large number of residents of that surrounding area had to relocate their dwellings resulting in the lost of their livelihoods. Afterwards, the Hyderabad Sanitation Project and Water Supply extended a helping hand towards displaced persons and helped them in resettling. The project, in all, helped in resettling at about 3,600 households and identified 4,600 families which require immediate support for the reestablishment of their economic productivity.

The Dowleswaram Barrage in the state of Andhra Pradesh is constructed on the last stretch of the River Godavari. It is an irrigation structure. The Godavari River empties its entire water into the Bay of Bengal after flowing a few miles from the Dowleswaram Barrage. Sir Arthur Thomas Cotton, a British irrigation engineer, constructed the Dowleswaram Barrage which helped in boosting the economy of the state in large scale. The village Dowleshwaram is at a distance of eight kilometers to the downstream of Rajamundry. Rajamundry is a large town situated on the left bank of Godavari River. The upstream, where the River is divided into two streams or distributaries called the Gautami to the left and the Vasistha to the right, forms the dividing line between the West Godavari and the East Godavari districts. The height of the Dowleswaram Barrage is 15 feet and its construction was completed in the year 1850. Adjoining two mid stream islands, the barrage is constructed in four sections. From east to west; Dowleshwaram is on the left, Ryali, Bobbarlanka and Vijjheswaram to the right, segregated by the islands in between. The two sections in the middle are smaller. The primary canals are there in the central part of the island for the central delta and one each on both the flanks, near Nidadavole and at Dowleshwaram. There is another canal branching off at Nidadavole called the Eluru canal towards the right following a contour flowing till Vijayawada, where a barrage was constructed by one of the junior colleagues of Sir Cotton, Capt. Orr, on the Krishna River. The Krishna Barrage was constructed exactly at the same place where the earlier barrage was present in the 1960s. In the year 1980, the Government of Andhra Pradesh undertook extensive renovation work of the barrage and a road was constructed on the top of it for motor vehicles.

The Gandipalem Reservoir is also known as the Gandipalem state reservoir which is situated in Andhra Pradesh. The Gandipalem Reservoir was constructed with the aim of saving the lives of a large number of people of different villages in Udaygiri Mandal from famine in the summer season. Another major objective behind the construction of the Reservoir was to provide water for the irrigation of about 600 square kilometers of land which are located far away from Pennar River. The major source of water for the Gandipalem reservoir is the Manneru River. This river is a tributary to the River Pennar. The length of the Manneru River is 130 kilometer which starts near the village Pillipalli of Kanigiri taluk of the district of Prakasam. Dokkalavagu, Pillaperu, Uppuvagu and Upputeru are the main tributaries of the Manneru River. Another reservoir in Andhra Pradesh is the Musi Reservoir. It is within the district of Nalgonda and is constructed across the Musi River.

The Osman Sagar is an artificial lake in the city of Hyderabad. It is famously called Gandipet and the lake is about 46 square kilometers and possesses a reservoir covering an area of 29 square kilometers. Osman Sagar Dam was built in the year 1920 by damming the River Musi, for supplying drinking water to the people of Hyderabad and also checking the devastation caused by flood to the city. During the rule of Mir Osman Ali Khan, the seventh Nizam of Hyderabad, the city witnessed a flood of devastating nature which subsequently led to the construction of this dam and the name also came from it. The Sagar Mahal, a princely guesthouse was erected close to the Dam as the last Nizam`s summer resort. This guesthouse is regarded as a heritage building overlooking a picturesque lake. This guest house is situated on the banks of the River Musi and it is in close proximity to the Osman Sagar Dam. This dam chiefly serves the purpose of drinking water for people living in the city of Hyderabad. The Osman Sagar Dam is one of the best tourist destinations in Hyderabad. At the time of rainy season, when the reservoir is filled with crystal clear water and the blowing of sweet breezes, tourists in large numbers visit this place. Another suitable tourist destination close to the Osman Sagar Dam is the Lake Himayat Sagar. The Srisailam Project is situated in the Rayalaseema Region across the River Krishna in the state of Andhra Pradesh. The Srisailam Project possesses a live storage capacity of 250 thousand million cubic feet. The Srisailam Project reservoir was firstly planned for the generation of hydropower but the same was afterwards changed to a multi-purpose facility station for irrigation and water supply. The left bank generates 6*150 MW of power and the right bank generates 7*110 MW of power. The project is situated in Rayalaseema Region of Andhra Pradesh. More than 102 villages in Mahaboobnagar and Kurnool districts were displaced as a result of the construction of Srisailam Hydro Electric Project at Srisailam.

The Ramagundam dam is situated in Karimnagar in the state of Andhra Pradesh. The approved capacity of the Ramagundam dam is 2600 MW. The sources of water for this dam are the Sri Ram Sagar Dam build across the River Godavari and a canal from the Pochampad Reservoir. The states benefiting from the Ramagundam dam are Tamil Nadu, Puducherry, Kerala, Goa, Karnataka and Andhra Pradesh. Andhra Pradesh Power Generation Corporation Limited took up the lead for the construction of the Dummaguden Dam across the Godavari River in the state of Andhra Pradesh. The Dummaguden Dam is owned and controlled by the Government of Andhra Pradesh-Commercial Enterprises. The Dummaguden Dam is at the Pamulapally village of the Bhadrachalam area in the district of Khammam. The Government invested at about Rs.1, 700/- crores for the construction of this hydel-based dam. Sunkesula Barrage is a structure of Tungabhadra Barrage Head Works close to the Sunkesula Village in the district of Kurnool in Andhra Pradesh. TBC, I & CAD DEPARTMENT, Government of Andhra Pradesh is the owner and in control of the Sunkesula Barrage project.
