Context: Prime Minister in December laid the foundation stone for the Ken-Betwa River Link Project, which aims to solve the water scarcity in the Bundelkhand region.
Origin of the Idea of Interlinking Rivers:
• Sir Arthur Cotton (19th Century): Proposed inter-basin water transfer to address irrigation challenges in India.
• M. Visvesvaraya (Early 20th Century): Advocated linking rivers to solve water scarcity and flooding issues.
• K.L. Rao (1970s): Suggested a National Water Grid to transfer surplus water to drought-prone regions.
• Dinshaw J. Dastur (1980): Expanded the idea with plans for Himalayan and Peninsular links.
• National Perspective Plan (1980): Formalized by the Ministry of Water Resources with the establishment of the National Water Development Agency (NWDA) in 1982.
Components of the Interlinking of Rivers Project:
• Himalayan Rivers Component:
• 14 proposed links, including Ganga-Brahmaputra basin rivers.
• Focus: Flood control, hydropower generation, and water transfer to central India.
• Peninsular Rivers Component:
• 16 proposed links, including Krishna, Godavari, and Cauvery rivers.
• Aim: Irrigation, drought mitigation, and inter-basin water sharing.
What is the Interlinking of Rivers Project?
The ILR Project involves transferring water from surplus river basins to deficient regions via a network of canals, dams, and reservoirs.
• Managed by the National Water Development Agency (NWDA) under the Ministry of Jal Shakti, it aims to enhance water availability, agricultural productivity, and disaster mitigation.
Features:
• Himalayan and Peninsular Links: Divided into 14 Himalayan and 16 Peninsular links for water redistribution.
• Intra-State Links: Focused on addressing state-specific water demands.
• Infrastructure Development: Includes canals, reservoirs, and hydropower facilities for water transfer.
• Integrated Approach: Combines irrigation, hydroelectric power generation, and water supply for domestic and industrial use.
• Massive Scale: Covers 30 river links with a projected cost of ₹5.5 lakh crore.
Benefits of Interlinking Rivers:
• Flood and Drought Mitigation: Redistributes excess water from flood-prone regions like Bihar to drought-prone areas like Bundelkhand.
• Boost to Agriculture: Increases irrigated land, ensuring food security and reducing dependency on monsoons.
• Hydropower Potential: Facilitates the generation of renewable energy from dams and reservoirs.
• Economic Growth: Improves water availability for industries, enabling regional economic development.
• Waterway Expansion: Promotes inland navigation, reducing transportation costs and environmental impact.
Challenges of Interlinking Rivers:
• Environmental Concerns: Loss of biodiversity, deforestation, and threats to protected areas like the Panna Tiger Reserve.
• High Costs: Massive financial burden for construction, maintenance, and rehabilitation of displaced communities.
• Social Displacement: Large-scale projects can displace populations, affecting livelihoods and social structures.
• Inter-State Disputes: Conflicts over water-sharing agreements may escalate, as seen in the Cauvery and Krishna River disputes.
• Ecosystem Disruption: Alters riverine ecosystems, impacting aquatic life and the health of downstream deltas.
Way Ahead:
• Comprehensive Impact Assessment: Conduct multidisciplinary studies to evaluate environmental, social, and economic impacts.
• Stakeholder Engagement: Foster collaboration among states, communities, and experts for equitable decision-making.
• Modern Water Management: Prioritize innovative solutions like drip irrigation, watershed management, and desalination.
• Climate Change Adaptation: Integrate climate-resilient policies to ensure sustainable water use.
• Focus on Regional Projects: Implement smaller, state-specific water-sharing initiatives to reduce risks.
Conclusion:
While the Interlinking of Rivers Project holds promise for addressing water scarcity and boosting agricultural productivity, it demands a balanced approach to mitigate environmental and social impacts. A sustainable and inclusive strategy is essential to achieve long-term benefits without compromising ecological integrity or societal harmony.
