River Linking Is Not the Solution
Context
The debate over river linking has resurfaced amid growing concerns about water shortages and inter State disputes. However, serious questions remain about its ecological impact, legal complexities, potential displacement of communities and ability to address India’s water challenges in a sustainable manner.
Key Highlights
– River linking involves transferring water from one river basin to another, usually from regions considered to have surplus water to areas facing water shortages.
– Inter State river disputes demonstrate that water management has complex constitutional, legal, political and ecological dimensions.
– The Inter State Water Disputes Act, 1956, provides the legal framework for resolving disputes related to inter State rivers and river valleys.
– Large scale river linking projects can alter natural river flows, sediment movement, groundwater recharge and aquatic ecosystems.
– Climate change has made the classification of river basins as permanently water surplus or water deficit increasingly uncertain, as rainfall patterns are becoming more variable.
– Projects such as Ken Betwa and other proposed river linking schemes highlight the continuing political and developmental appeal of transferring water between river basins.
– Demand side management, water conservation, watershed development, groundwater recharge and efficient irrigation can often help address water stress without relying on massive inter basin transfers.
– Sustainable water governance requires cooperation among States rather than treating river linking as a universal technological solution.
Way Forward
India should prioritise basin level planning, water conservation, groundwater recharge, efficient irrigation and demand management before undertaking large scale inter basin transfers. Cooperative federalism and thorough ecological assessments must remain central to addressing the country’s water-security challenges.
