Interlinking of Rivers in India: Issues & Challenges (GS paper 1, Geography ,GS paper 3 )


INTERLINKING RIVER PROJECT


 The interlinking of rivers has two components: the Himalayan component and a Peninsular one. All interlinking schemes are aimed at transferring of water from one river system to another or by lifting across natural basins. The project will build 30 links and some 3000 storage to connect 37 Himalayan and Peninsular rivers to form a gigantic South Asian water grid. The canals, planned to be 50 to 100 meters wide and more than 6 meters deep, would facilitate navigation. The estimates of key project variables - still in the nature of back-of-the-envelope calculations - suggest it will cost around US $ 123 billion (or Indian Rs 560,000 crores, at 2002 prices), handle 178 km of inter-basin water transfer/per year, build 12,500 km of canals, create 35 giga watt of hydropower capacity, add 35 million hectares to India’s irrigated areas, and create an unknown volume of navigation and fishery benefits. Similarly, 3700 mega watt would be required to lift water across major watershed ridges by up to 116 meters. The Fig. 2. River Links under the National Perspective Plan.

1. Major advantages of ILR
 • Create the potential to increase agricultural production by an additional 100 per cent over the next five years;
 • Avoid the losses of the type that occurred in 2002 to the extent of $550 million by the loss of crops because of extreme draught or flood condition;
• Save $ 565215000 a year in foreign exchange by avoiding importing oil;
• Unify the country by involving every Panchayat as a share holder and implement agency;
 • Provide for enhancing the security of the country by an additional waterline of defense;
• Provide employment to the 10 lakh people for the next 10 years;
• Eradicate the flooding problems which recur in the northeast and the north every year;
 • Solve the water crisis situation by providing alternative, perennial water resources;
 • The large canals linking the rivers are also expected to facilitate inland navigation too;
 • Increasing food production from about 200m tones a year to 500m;
 • Boost the annual average income of farmers, from the present $40 per acre of land to over $500.

2. Major disadvantages of ILR

• Environmental costs (deforestation, soil- erosion, etc.)
 • Rehabilitation: not an easy task
 • Social unrest/Psychological damage due to forced resettlement of local people (for example, Sardar Sarovar Project)
• Political effects: strained relationship with neighbors (Pakistan, Bangladesh)

 3. Issues and challenges Inter-

River Linking Project involves multifaceted issues and challenges related to economic, ecological, and social costs. On this note, Iyer (2003) very sharply states that “We have had great difficulty in completing even a single project successfully and we want to embark on thirty massive projects at the same time.” IRL project has caused much anger and protest in our neighbouring nation, Bangladesh. It is grappled with fear that diversion of water from the Brahmaputra and the Ganges, which provide 85% of the country’s fresh water flow in the dry season, would result into an ecological disaster. Indian National Water Development Agency plans to dig hundreds of reservoirs and more than 600 canals. This may trigger an alarm among environmentalists to raise their voice against this plan. Environmentalists are quite concerned about the ecological impact of the project of such huge magnitude. Shiva (2003) very aptly remarked that the water flowing into the sea is not waste; it is a crucial link in the water cycle. With the link broken, the ecological balance of land and oceans, freshwater and sea water, also gets disrupted Shiva considered ILR violence to nature: “Violence is not intrinsic to the use of river waters for human needs. It is a particular characteristic of gigantic river valley projects which work against, and not with, the logic of the river.” As this project is of massive estimated cost, a long term planning and a sound financial simulation are required to meet the standard of due diligence for such proposals. The huge expenditure may likely generate fiscal problems that are difficult to handle. The maintenance cost and physical position of the dams, canals, tunnels, and captive electric power generation will also involve huge financial burdens. This certainly requires financial assistance from the private sector, as well as global capital agencies. Mobilization of global capital may ultimately entail the risk of destroying social welfare measures. The rehabilitation of project-affected people in water infrastructure projects will also pose a burning question before the concerned authorities. The construction of reservoirs and river linking canals in the peninsular component alone expect to displace more than 583,000 people and submerge large areas of forest, agriculture and non-agriculture land. Transfer of water is bound to be unacceptable as no state is likely to transfer water to another foregoing possible future use of such water. Domestic and regional geo-politics play a pivotal role on the discussions on ILR. As of now, there is no mechanism as of now to deal with matters concerning interbasin transfers. There are also important institutional and legal issues to be sorted out. As per the latest information disclosed in the Indian Parliament, Union Minster of Parliamentary Affairs and Water Resources informed the house that NWDA has spent Rs 350.5 crores on various Inter-River Linking Project (IRL) studies up to February 2012 and Water Resource Ministry had not received certified copy of guidelines, as issued by the Hon’ble Supreme Court of India. Some of the ILR (inter-linking of rivers) schemes have international implications, with a possible impact on countries like Bhutan, Nepal and Bangladesh. Each of the 30 schemes of the ILR is supposed to get through several statutory, legal and procedural steps. None of the schemes have gone through any of it. The Union ministry of environment and forests has already said no to the project. No state is ready to give water to another state. In India‘s constitution, water is essentially a state subject. Several states including Kerala, Andhra Pradesh, Assam and Sikkim have already opposed ILR projects. There will be several environmental impacts of ILR including submergence of land and forests, destruction of rivers, aquatic and terrestrial biodiversity, downstream impacts, destruction of fisheries, salinity ingress, pollution concentration, destruction of groundwater recharge and increased methane emission from reservoirs, among others. Unfortunately there is no comprehensive assessment of all such possible impacts for a single link in any credible way.

 5. ENVIRONMENTAL IMPACT

 The Ministry of Environment and Forests, Government of India, on 23rd of May 2003, had shown a very serious concern about the environmental issues related to the proposed interlinking project. Bandyopadhyay (2003) asked the question “How are the environmental damages that may be caused by the interlinking project identified and their financial costs estimated, if at all?” Martin (2003) clearly warned that linking rivers like straight pipelines without looking at the ecological impact may be very harmful for our environment. Scientists are also doubtful that river diversion may bring significant changes in the physical and chemical compositions of the sediment load, river morphology and the shape of the delta formed at the river basin. Water related diseases, such as Malaria, and Filariasis can spread through stagnant or slow moving water in the irrigation command area. The ecologically un-informed economic development activities, like widespread water logging and the resulting desertification in the catchment areas of many large irrigation projects, can also be cited. Roy (1999) states that, “In India, fifty million people are estimated to have been displaced in the last five decades by the construction of dams, power plants, highways and such other infrastructure development projects. Subsequently no more than one-fourth of them could be assisted to regain their livelihoods”. Wolfensohn (1995) remarked that ‘Such social injustice can destroy economic and political advances. With the link broken, the ecological balance of land and oceans, freshwater and sea water, is also disrupted (Shiva 2003). A section of scientists argue that large dams and reservoirs also cause earthquakes. The controversies over koina dam, Tehri dam are few such examples. In view of a spate of earthquakes being experienced, the presence of large number of reservoirs will prove to be disastrous in case of any such eventuality. Inter-linking a toxic river with a non-toxic one will have a devastating impact on all our rivers and, consequently, on all human beings and wild life. Shiva (2003) considers ILR to be an act of violence against nature: “Violence is not intrinsic to the use of river waters for human needs. It is a particular characteristic of gigantic river valley projects that work against, and not with, the logic of the river. These projects are based on reductionist assumptions, which relate water use not to nature’s processes but to the processes of revenue and profit generation… Rivers, instead of being seen as sources of life, become sources of cash. In Worster’s words, the river ends up becoming an assembly line, rolling increasingly toward the goal of unlimited production. The irrigated factory drinks the region dry.” Iyer (2003) is acerbic in his comments on IRL projects: “Are rivers bundles of pipelines to be cut, turned around, welded and rejoined? This is technological hubris – arrogance – of the worst description, prometheanism of the crassest kind. The country needs to be saved from this madness.” 6. CONCLUDING REMARKS Successful implementation of this project largely looms upon timely release of water from the surplus basin to the deficit basin. The Government of India has constituted a task force to examine the project, comprised of experts from science, engineering, economics, and social sciences and including as official stakeholders one member from a water deficit state and one member from a water surplus state. It will address the following broad issues: provide guidance for norms of appraisal of individual projects vis-à-vis their economic viability, socio-economic impacts, environmental impacts, and preparation of resettlement plans; develop a mechanism for speedy consensus amongst states; prioritize different projects; propose organizational structures for implementing the project; consider funding modalities for the project; and consider the international ramifications of the project. The completion date for achieving the goal of the interlinking project is December 31, 2016 (Ministry of Water Resources 2002). Amidst rapid development and urbanization, outdated systems of managing water resources; it is the high time for India to come forward in all-out manner to transform this dream project into a big reality. Fact is that the ILR projects are site and requirement specific depending upon the hydrological, geological, topographical and regional conditions. It is essential that needed environmental safeguards are properly implemented in a coordinated manner by various agencies. We have to develop a range of models that agree to use shared data sets and explore definitions of water use/ consumption. If water transferred from water abundant rivers to water deficit areas, there would be adequate supply for everyone in every part of the country. It also appears to promote national integration and a fair sharing of the country’s natural water wealth. India’s river linking project shows and promises a great concern for water conservation and optimum use of available water resources. Undoubtedly, it is the need of the hour to have a water mission like as IRL, which will enable availability of water to the fields, villages, towns and industries throughout the year, even while maintaining environmental purity to combat with both fold and drought simultaneously. The problem of providing domestic water supplies in areas away from the rivers will largely remain unsolved, even if the interlinking project is completed.
