The tussle between Odisha and Chhattisgarh over projects in the upstream of Mahanadi in the neighbouring state is in the news lately. Subhashish Mohanty of The Telegraph provides details of the projects, their impact on Odisha and the state’s demands
Why is Mahanadi important?
Odisha is predominantly an agrarian economy and about two-thirds of the state’s population depend on agriculture. The river is the lifeline for 16 of its 30 districts. The Mahanadi delta covers 95,000sqkm and the delta region has a 200km coastline. The availability of safe drinking water and sanitation largely depend on the Mahanadi. Also, Odisha is a cyclone-prone state and the mangroves in the delta are the first line of defence against the sea. Adequate water in the Mahanadi is an important prerequisite to maintain the fragile eco-system
What is Odisha’s objection?
• Chhattisgarh has taken up construction of many major and medium projects on the upper Mahanadi without consulting Odisha. The construction of seven barrages poses a serious threat to the non-monsoon (September to June) water flow to the Hirakud reservoir. Chhattisgarh projects them as minor schemes, but these are meant for industrial purposes
• Once the projects are complete, flow to the downstream will reduce. This will affect the fragile ecosystem of the Mahanadi — particularly the Satkosia, Bhitarkanika wetlands, Chilika lagoon, Gahirmatha turtle habitat and the Mahanadi delta itself. Drinking water supply in the state will also be affected
Odisha’s stand
When the Hirakud dam was built as a central project in 1957, Odisha was assured of a minimum availability of 12.28 million acres feet of water. This was accepted by the undivided state of Madhya Pradesh. At this point, Odisha wants:
• An immediate stop to all projects on the Mahanadi in Chhattisgarh
• Appointment of an independent fact-finding committee consisting of engineers, retired judges, hydrologists and agricultural experts to collect data on the use of Mahanadi water
• Non-approval of Chhattisgarh’s proposal to have a joint control board. Odisha feels the board will not be able to protect the interests of the state and would have no legal power to enforce its decision
Chhattisgarh’s stand
All projects on the Mahanadi have been built following the state rules. Even after its proposed (disputed) projects are completed, enough water will remain in Mahanadi to fill the Hirakud dam roughly 5-7 times
Centre’s stand
A memorandum of agreement signed between Madhya Pradesh and Odisha in 1983 on the Mahanadi provided for setting up a joint control board to review and plan inter-state irrigation projects on the river basin. The committee has not been formed yet. It should be formed
Option before Odisha
Approach judiciary to form a water dispute tribunal for settling the issue
