What Happened
The governments of Bihar and Jharkhand signed a Memorandum of Understanding on sharing the waters of the Sone river. The ceremony took place in New Delhi in the presence of Union Home Minister Amit Shah and Union Jal Shakti Minister CR Patil. Bihar Chief Minister Samrat Choudhary and Jharkhand Chief Minister Hemant Soren signed the MoU, along with senior officials from both states and the Centre.
Officials characterized the agreement as resolving a long-running dispute over the Sone river and associated Bansagar project water allocations that had persisted for about 25 years since earlier arrangements were made in 1973. Shah described the deal as a model of cooperative federalism and highlighted its aim to secure irrigation and drinking water for large rural areas in both states.
Why It Matters
Analysts note that the MoU is positioned as a permanent resolution to a contentious inter-state water-sharing issue, potentially stabilizing water availability for irrigation and drinking water in several districts of Bihar and Jharkhand. Shah framed the agreement as part of a broader push for multiple water accords this year, emphasizing improved access to water for farming communities and rural populations.
Background
The dispute traces back to a 1973 agreement involving Uttar Pradesh, Madhya Pradesh, and undivided Bihar regarding Sone river waters and the Bansagar dam project. The creation of Jharkhand in 2000 altered the distribution landscape, with Jharkhand claiming a larger share due to its catchment area. The new MoU follows years of negotiations culminating in the signing event in New Delhi.
