Ken-Betwa DPR Approved, 4 Others Pending: Cost & Timeline Data

The Ken-Betwa Link Project (KBLP), a cornerstone of India's ambitious inter-linking of rivers (ILR) program, received formal approval for its Detailed Project Report (DPR) in December 2021. This approval, following decades of deliberation, signifies a tangible step in addressing regional water imbalances. While KBLP moves forward, at least four other major river linking projects remain in various stages of planning or approval, highlighting the complex challenges inherent in such large-scale infrastructure initiatives.

The Inter-Linking of Rivers Program: A Historical Overview

The concept of inter-linking rivers in India dates back to the 19th century, with formal proposals gaining traction in the 1970s. The National Perspective Plan (NPP), formulated in 1980 by the Ministry of Water Resources, outlined 30 links: 16 under the Peninsular Component and 14 under the Himalayan Component. The National Water Development Agency (NWDA) was established in 1982 to conduct detailed studies.

The program aims to transfer surplus water from water-rich basins to water-deficit basins. This is intended to mitigate floods, alleviate droughts, enhance irrigation potential, and generate hydropower. However, the program has faced consistent scrutiny regarding environmental impact, displacement, and economic viability.

Ken-Betwa Link Project: DPR Approval and Key Data

The Ken-Betwa Link Project is the first project under the NPP for which the DPR has been approved. It involves transferring water from the Ken river in Madhya Pradesh to the Betwa river in Uttar Pradesh.

Key components of KBLP include:

• Daudhan Dam: A multi-purpose dam on the Ken River.
• Link Canal: A 221 km long canal, including a 2 km tunnel.
• Power Houses: Two powerhouses.

The project is designed to provide annual irrigation to a substantial area, supply drinking water, and generate hydropower. Its approval marks a critical juncture for the ILR program, setting a precedent for other projects.

Pending River Linking Projects: Status and Challenges

Beyond Ken-Betwa, several other links are under various stages of investigation and preparation. Four prominent projects that are still awaiting DPR approval or significant progress include:

1. Damanganga-Pinjal Link: Aims to transfer water from the Damanganga basin to the Pinjal basin to augment water supply to Mumbai.
2. Par-Tapi-Narmada Link: Proposed to transfer surplus water from the Western Ghats rivers (Par, Tapi) to the water-deficit areas of North Gujarat.
3. Mahanadi-Godavari Link: Part of the Peninsular component, this link is envisioned to transfer water from the Mahanadi basin to the Godavari basin.
4. Manas-Sankosh-Teesta-Ganga Link: A major Himalayan component link, intended to transfer water from the Manas and Sankosh rivers to the Ganga basin.

These projects face a range of challenges, from inter-state disputes over water sharing to environmental clearances and rehabilitation issues. The sheer scale and multi-state involvement complicate their progression.

Comparative Status of Major River Linking Projects

This table illustrates the varying stages of progress and the persistent hurdles each project encounters.

Cost and Timeline Data: An Analysis of KBLP and Implications

The Ken-Betwa Link Project is estimated to incur significant costs. The Union Cabinet approved the project with an estimated cost of ₹44,605 crore at 2020-21 price levels. This cost is to be borne by the Central Government (90%) and the two states (Madhya Pradesh and Uttar Pradesh, 10%). The project is expected to be completed within eight years from the date of commencement.

Historical trends show that large infrastructure projects in India often face cost overruns and time delays. The initial estimates for many ILR projects were significantly lower, and the KBLP's current estimate reflects revised assessments. This escalation is a critical factor influencing the viability and political will for other pending projects.

For instance, the original estimates for several ILR projects were prepared decades ago. Recalculating these costs to current price levels, while also factoring in updated environmental mitigation and rehabilitation expenses, often leads to substantial increases. This financial burden is a major deterrent for states, particularly when inter-state agreements are difficult to achieve.

Environmental and Social Considerations: A Persistent Hurdle

The environmental impact assessment (EIA) and social impact assessment (SIA) processes for river linking projects are complex and often contentious. The KBLP, for example, involves the diversion of forest land within the Panna Tiger Reserve. This required specific clearances and mitigation plans, including provisions for wildlife management and rehabilitation.

Similarly, the Par-Tapi-Narmada Link has faced significant opposition from tribal communities concerned about displacement and loss of livelihoods. Such concerns highlight the need for robust and transparent processes for environmental and social safeguards, as well as fair rehabilitation and resettlement policies. The delays in many projects are directly attributable to these unresolved issues.

Funding Mechanisms and Inter-State Cooperation

The funding model for KBLP, with a substantial central government contribution, might serve as a template for other projects. However, securing consensus among beneficiary and donor states remains a challenge. Water is a state subject under the Indian Constitution, making inter-state water disputes a perennial issue. The Inter-State Water Disputes Act, 1956, provides a framework for resolving these, but the process can be protracted.

Future projects will require innovative funding models, potentially involving public-private partnerships, and stronger mechanisms for inter-state dialogue and agreement. The success of KBLP in navigating these complexities will offer valuable lessons for the broader ILR program.

UPSC Relevance and Future Outlook

The inter-linking of rivers program is a recurring topic in the UPSC Civil Services Examination, particularly in GS Paper 3 (Economy and Environment). Questions often revolve around the economic viability, environmental implications, social impact, and inter-state water disputes associated with these projects.

Understanding the specific status of projects like Ken-Betwa, along with the reasons for delays in others, provides a data-driven perspective beyond general arguments. The trend towards higher cost estimates and more stringent environmental clearances is a critical development for aspirants to analyze.

Policy Evolution in Water Resource Management

India's approach to water resource management has evolved, moving from large-scale dam construction to a more integrated and decentralized strategy. However, the ILR program represents a continuation of the large-scale infrastructure approach. The shift in policy towards 'per drop more crop' and 'Jal Shakti Abhiyan' emphasizes efficient water use and conservation, complementing rather than replacing large infrastructure projects.

This evolution suggests a multi-pronged strategy where large inter-basin transfers are considered alongside localized conservation and efficiency measures. Aspirants should analyze how these different policy approaches interact and sometimes conflict. For broader policy analysis, consider Current Affairs Integration: A Framework for UPSC Preparation.
