Interlinking of Rivers in India: Issues & Challenges

On paper, India has abundant water resources. Water is not always available when it is most needed, however, and neither is it evenly distributed throughout the country. Various schemes have been devised over the years to shift water from the wet north-east to the drier western parts of the country. Since the s, the Bharatiya Janata Party has advocated for the construction of a series of canals that would link various rivers across the country.

Water could then be shifted between those rivers according to the needs of various parts of the country. The cost of building those canals, the interstate politics of water sharing and the possibility of inadvertent environmental degradation are factors that are likely to slow, or even prevent, the realisation of the scheme. India receives the equivalent of four million gigalitres of rain annually. That rainfall does not fall evenly across the country, however, and neither does it fall consistently throughout the year.

It further suggests that large parts of Haryana, Maharashtra, Andhra Pradesh, Rajasthan, Gujarat, Madhya Pradesh, Karnataka and Tamil Nadu not only receive limited rainfall, but also large year-to-year variation in water availability. For decades, Indian engineers, hydrologists and political leaders have attempted to find ways to move water from areas of abundance to regions that have limited water supplies.

The Indian land mass can be divided into 19 major river basins. The per-capita water resource availability of those basins varies from a low of kilolitres in the Sabarmati basin to 20, kilolitres in the Ganges-Brahmaputra-Meghna river system.

Similarly, there is considerable variation in the amount of water withdrawn from those basins. As little as kilolitres are withdrawn from the Meghna basin and as much as 1, kilolitres in the Indus basin.

Approximately two-thirds of Indian agriculture is rain-fed, with most of the remainder using groundwater to irrigate crops. In some parts of the country, groundwater is being used at such a rate that it surpasses the natural recharge of aquifers. Large infrastructure projects, such as dams, reservoirs and canals to store and move water around, are seen as vital to that vision.

Those dams, as well as the efficiencies brought about by the Green Revolution, helped India to avoid famine and lifted living standards. India can only store about 30 days of rainfall , compared to days in major river basins and arid areas of developed countries, however, suggesting that the construction of more storage infrastructure is appropriate. Since the s, government investment in surface water irrigation has declined and Indian farmers have drilled more groundwater wells.

In , when groundwater wells were uncommon, there were about , wells across the country and most of them were shallow and dug by hand. Many of them continued to use oxen to draw water. By , however, the number of wells had increased to 22 million, with most using electric- or diesel-powered pumps to draw water from deep underground. The number of wells has continued to increase, by about one million per year. In Haryana and Punjab, the water table is falling by more than one metre per year and, according to some estimates, India is extracting groundwater twice as fast as it can be recharged.

British engineers first thought of inter-linking Indian rivers in Those plans were revived by Indian politicians after independence and continue to inspire similar ideas. Such a grid would transport surplus water from the north to the drier south to alleviate floods and drought. A modern version of the water grid concept, known as the river interlinking project, has its origins in the National Perspective for Water Resources Development report that the Ministry of Water Resources released in It recommended the transfer of water from areas of surplus to water deficient regions.

The National Water Development Agency was established under that plan to complete a series of feasibility studies for the proposed links. In the ruling Bharatiya Janata Party BJP , led by Prime Minister Atal Vajpayee, reinvigorated the plan and, in that year, the Supreme Court of India passed an order that the government should complete the construction of the interlinking project by A Task Force was established to further develop the project.

That Task Force concluded that by linking the rivers, irrigation could be provided to million hectares of land compared to million hectares through conventional sources and 34 gigawatts of hydroelectricity could be generated equal to one-sixth of the installed power capacity at the time. It is easy to do interlinking on paper. The interlinking of rivers, initially at basin rather than national level, was revived again by the Narendra Modi-led BJP government in If each link currently under consideration were to be built, 15, kilometres of canals and 3, dams would be constructed.

The scheme aims to move water from areas where there is believed to be a surplus of water to areas that experience water scarcity. The scheme initially had two components. The Himalayan section has 14 links, and is expected to transport 33, gigalitres of water per year. The peninsular component has 16 links and will transport , gigalitres per year. As most of the Himalayan rivers are fed by glacier melt and those in peninsular India are rain-fed, those two components face different water supply constraints.

The Himalayan section depends on stable rates of glacial formation and melt, while the peninsula component depends on steady monsoon events. The scheme broadly envisions transporting water from the relatively wet north-west of the country to the drier east. A third component was added in and focusses on linking 31 rivers within the borders of a single state. In September , the Godavari and Krishna rivers, the second- and fourth-longest in the country, were linked through a canal in Andhra Pradesh.

After some initial engineering challenges, including a breach of the canal shortly after its inauguration, the link is working as planned. The Chief Minister of Andhra Pradesh, Chandrababu Naidu, said that the link had improved water access in the Rayalaseema region and helped to manage the water needs of his state. The next phase of the Godavari-Krishna link involves the diversion of the Krishna River to the Penna, and ultimately, the Cauvery River.

That phase might not occur as smoothly as the first. Several interstate water sharing disputes, most prominently the one over the sharing of the Cauvery River between Karnataka and Tamil Nadu, will have to be resolved if the water transfer is to operate effectively.

Other linking projects could face similar challenges, particularly as states such as: Bihar; Odisha and Kerala, do not accept that they have surplus water resources to share with the rest of India.

It is also possible that a water sharing agreement will need to be finalised with Bangladesh, particularly in relation to any water transfer that involves the Brahmaputra or its tributaries. The Ken-Betwa link , another project that is close to being started, involves the construction of a kilometre canal to transfer water from the Ken to the Betwa river. It will provide water to the drought-prone Bundelkhand region between Madhya Pradesh and Uttar Pradesh.

The Indian Water Resources and River Development Minister, Nitin Gadkari, stated in June that the necessary clearances had been obtained for the project and that groundworks would soon commence. As those two projects took years of planning, and the interlinking of rivers has been discussed for decades, there is no guarantee that the other components of the national river interlinking scheme will be built in the near future.

The Congress Party has been hostile to the scheme in the past and continues to have doubts about its long-term value to the country. A change of national government is likely to slow progress.

Perhaps counterintuitively, there is also a chance that an increased reliance on canals and reservoirs will decrease Indian water security in the long term. An over-reliance on water infrastructure alters the supply-demand cycle and can lead to greater water insecurity. An increase in the water supply often leads to an increase in consumption, which can create vulnerabilities in the event of drought or a sudden water supply shortfall.

Critics of the interlinking scheme suggest that such grand infrastructure projects are not the only options available to India. Other options could have equal or better outcomes for water security, they include: increased irrigation efficiency; growing crops that are appropriate for the climatic conditions of the region in which they are grown; managing water demand; increasing rainwater harvesting; and ensuring that existing infrastructure is maintained and operating effectively.

Changes in the hydrological profile of Indian rivers, whether by climate change or changes in the volume of water withdrawn from them, could leave current surplus rivers with a deficit.

The amount of water in many of the Himalayan rivers, for instance, depends on the amount of glacial melt present in the system. It is assumed that regions and rivers with a surplus of water will continue to have abundant water supplies. If that situation changes, however, and those rivers no longer have surplus water to shift elsewhere, the basis for the whole interlinking concept could be compromised.

The river interlinking scheme was launched as a solution to the persistence of hunger and water insecurity in Indian society. It is hoped that the transfer of water from surplus areas to regions with a water deficit will increase Indian food production and lower food insecurity. India already produces enough food to feed its population, however, and while Indian farmers do not achieve the same crop yields per hectare as farmers in other countries, that is generally not because of a lack of water.

The interlinking of rivers is a grand infrastructure scheme that is designed more to impress and enthrall Indian voters than meaningfully improve food and water security. Print Email. Key Points India has a long history of designing, but rarely implementing, grand infrastructure projects that aim to move water from high rainfall areas to arid regions. While the current BJP government supports those grand infrastructure projects, most remain in the planning stage and any change in government is likely to halt further progress, particularly as the national river interlinking scheme will take years to complete.

Interstate disputes and an unwillingness to share water across state boundaries could also frustrate those plans. Critics of the river interlinking scheme suggest that India has other options available to it that would improve its water security. Summary On paper, India has abundant water resources.

Interlinking of Rivers in India: International and Regional Legal Aspects

Though the interlinking of river programme is the most ambitious anti-poverty measure ever conceptualised by the Indian Government, it has attracted a lot of criticism due to a wide of range of social, political, economic and environmental costs associated with it. India is one of the few countries in the world gifted with considerable water resources. Against this backdrop, the Interlinking of Rivers Programme has been given a big push by the NDA Government in order to address twin problems of floods and droughts. However, most of it comes over a 4-month period — June through September.

The rivers in India are truly speaking not only life-line of masses but also for wild-life. The rivers play a vital role in the lives of the Indian people.

The Indian Rivers Inter-link is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking Indian rivers by a network of reservoirs and canals to enhance irrigation and groundwater recharge , reduce persistent floods in some parts and water shortages in other parts of India. The Inter-link project has been split into three parts: a northern Himalayan rivers inter-link component, a southern Peninsular component and starting , an intrastate rivers linking component. NWDA has studied and prepared reports on 14 inter-link projects for Himalayan component, 16 inter-link projects for Peninsular component and 37 intrastate river linking projects. The average rainfall in India is about 4, billion cubic metres, but most of India's rainfall comes over a 4-month period — June through September. Furthermore, the rain across the very large nation is not uniform, the east and north gets most of the rain, while the west and south get less.

The core objectives of the paper are to study issues and challenges in interlinking of rivers in India and to study environmental impact of Inter-River Linking.

After recording above normal rains between July 6 and July 11, monsoon appears to be slowing down, sparking concerns in the agriculture sector, according to experts. The sluggish monsoon has impacted the sowing of summer cops. But in northeastern India, floods have caused widespread damage, with several lives being lost as a result of flooding.

Interlinking of River: Issues and Challenges

Climate change events cause erratic spatial and temporal variability in rainfall, temperature, humidity, etc. At the same time, water availability is also under pressure due to climate change and overexploitation of water resources. In a monsoonal climate that is already erratic and highly seasonal in nature, this increased variability due to climate change will further impact water availability and salt water intrusion. To overcome such problems, one of the most effective ways is interlinking of rivers. It is the interbasin water transfer from the water surplus rivers to water deficit rivers or regions.
