Answer

River-linking projects, such as the Ken-Betwa Project, are designed to address India’s water scarcity by transferring surplus water from one river basin to another, primarily for irrigation and drinking water supply. While they offer solutions to drought-prone areas, these projects face criticism due to environmental concerns, like disruption of ecosystems, biodiversity loss, and displacement of communities.

River-linking Projects Aim to Address Water Scarcity

• Improved Irrigation Facilities: River-linking projects like the Ken-Betwa aim to transfer water to drought-prone areas, enhancing irrigation.
  For example: The project will divert water to Bundelkhand, a region facing chronic water shortages and low agricultural productivity, improving farming.
• Increased Water Availability: These projects seek to replenish water-deficient river basins and ensure consistent water supply for human consumption and agriculture.
  For instance: The Betwa basin, facing water scarcity due to extensive irrigation, could receive a more reliable water supply through the interlink.
• Hydroelectric Power Generation: River-linking projects often include hydroelectric power plants to generate electricity alongside water supply, addressing energy demands.
  For example: The Daudhan Dam, part of the Ken-Betwa project, will generate hydroelectric power while providing water for nearby regions.
• Flood Control: They aim to mitigate floods in water-surplus areas by redistributing excess water to regions with insufficient water.
  For example: Redirecting water from the Ken basin to the Betwa could help reduce flood damage during high rainfall seasons in flood-prone areas.
• Supporting Economic Growth: River interlinking can contribute to economic growth by providing water for industries, agriculture, and drinking purposes.
  For instance: Consistent water supply could enhance agricultural output and improve living conditions, stimulating local economies in water-deficient areas.

Opportunity Cost and Environmental Repercussions

• Ecological Damage: River interlinking can harm ecosystems, especially when infrastructure is built in sensitive areas like wildlife reserves.
  For example: The Daudhan Dam, located within the Panna Tiger Reserve, risks disrupting the habitat of endangered species and destroying forest cover.
• Displacement of Communities: Large-scale river-linking projects may displace communities living in affected areas, disrupting their livelihoods and way of life.
• Decreased Biodiversity: River diversions can alter natural water flow, affecting biodiversity and the delicate balance of aquatic ecosystems.
  For example: Redirecting water to the Betwa river could upset aquatic life, as species adapted to the Ken river’s unique flow patterns may not thrive.
• Long-Term Water Management Issues: The assumption that such projects will provide a permanent water solution may overlook future challenges, such as changing rainfall patterns.
• Financial Resources and Opportunity Cost: Investing large sums in river-linking projects could divert resources from more sustainable water management solutions like conservation or rainwater harvesting.
  For example: The ₹44,605 crore spent on the Ken-Betwa project could have been used for improving watershed management or restoring natural water sources.

Measures to Maximize Benefits and Ensure Sustainable Development

• Environmental Impact Assessments: Conduct thorough and transparent environmental assessments before initiating large projects to minimize ecological harm.
  For example: An assessment of the Ken-Betwa project could help identify sensitive areas like wildlife habitats and propose mitigation strategies to minimize destruction.
• Improving Water Conservation: Emphasize water conservation strategies alongside river-linking projects to reduce dependence on interlinked rivers.
  For example: Enhancing natural storage, such as building check dams and promoting water-efficient irrigation techniques, can complement river-linking for sustainable water use.
• Integrating Stakeholder Input: Involve local communities, environmentalists, and experts in the planning and decision-making process to ensure the project benefits all stakeholders.
  For instance: Consulting local farmers in Bundelkhand about water management practices could provide insights on sustainable farming practices, making the project more effective.
• Monitoring and Adaptive Management: Regular monitoring of environmental and social impacts allows for adaptive changes to minimize negative consequences over time.
  For instance: Ongoing monitoring of the Ken-Betwa project’s impacts on water quality, local ecosystems, and communities could help modify its operations to reduce harm.
• Strengthening Ecosystem Restoration: Undertake measures to restore affected ecosystems, such as afforestation and wildlife conservation programs, to offset environmental damage.

While river interlinking projects offer solutions to scarcity, they often come with environmental drawbacks. To enhance their effectiveness, it is essential to focus on comprehensive environmental assessments, adopt watershed management strategies, and encourage community-driven conservation efforts. Ensuring ecological balance alongside resource distribution will promote sustainable development and long-term resilience.
