Context: Environmentalists have expressed concern over the massive diversion of fresh water from the Brahmani river basin, which could pose a grave threat to the famous mangrove vegetation in Odisha.
- The Talcher-Angul coal mines, steel and power plants as well as the Kalinganagar steel and power hub are drawing enormous quantities of fresh water from the Brahmani river.
- The Brahmani is a major seasonal river in the Odisha state of eastern India.
- The Brahmani is formed by the confluence of the Sankh and South Koel rivers.
- Together with the river Baitarani, it forms a large delta before emptying into the Bay of Bengal at Dhamra.
- Bhitarkanika — a notified Ramsar wetland — is spread over 195 sq. km and is home to 62 mangrove species.
- Proportionate fresh water flow from the Brahmani river basin and the Kharasrota river keep the salinity level of the water along the shore down.
