Sone River Agreement Revives Inter State Water Cooperation

Context

Bihar and Jharkhand have reached an understanding on the sharing of Sone River water, providing fresh momentum to long pending irrigation, reservoir and river linking initiatives in water stressed regions.

The agreement assumes significance as it seeks to address the competing interests that emerged after the bifurcation of Bihar and Jharkhand, particularly between upstream and downstream water users. It highlights the importance of cooperative mechanisms for managing shared river resources.

Key Highlights

• Bihar is expected to receive an agreed quantity of water at the Indrapuri Barrage, while Jharkhand will be able to utilise water for designated projects.
• The arrangement aims to safeguard irrigation in Bihar’s Shahabad region while improving water availability in Jharkhand’s Palamu Garhwa belt.
• Clear reservoir operation protocols and accurate, regularly shared flow data are crucial, particularly during periods of low water availability.
• Greater political and administrative coordination can help resolve water allocation concerns before they escalate into prolonged legal disputes.
• The agreement demonstrates how cooperative federalism can facilitate the equitable management of shared natural resources.

Key Concepts

• Sone River: A major southern tributary of the Ganga. It originates near Amarkantak and flows through parts of central and eastern India before joining the Ganga.
• Riparian State: A State through or along which a river flows. In the context of inter State rivers, riparian States may have competing claims over the use and distribution of water.
• Article 262: A constitutional provision that empowers Parliament to provide for the adjudication of disputes relating to the waters of inter State rivers and river valleys. It also allows Parliament to restrict the jurisdiction of courts in such disputes.
• Inter State River Water Disputes Act, 1956: The legislation provides a framework for establishing tribunals to adjudicate inter State river water disputes that cannot be resolved through negotiations.

Way Forward

• Translate the agreement into clear, transparent and enforceable water sharing and reservoir operation rules.
• Establish jointly monitored and independently verifiable flow measuring systems and ensure timely sharing of hydrological data.
• Ensure that water allocation safeguards environmental flows and downstream livelihoods.
• Create a permanent river basin level coordination mechanism involving the concerned States and relevant authorities.
• Strengthen real-time data sharing and collaborative reservoir management, especially during droughts and lean flow periods.
• Promote negotiated solutions and institutional cooperation so that technical disagreements do not develop into prolonged inter-State conflicts.
