Stakeholders come together to halt pollution in Khari river, Ahmedabad - a paper in Economic and Political Weekly (2006)
The paper describes the efforts made to reduce pollution in river Khari, Gujarat, contaminated due to discharge of industrial effluents Posted on 18 May, 2009 03:55 PM

This paper published in the Economic and Political Weekly describes the case of river Khari in Gujarat, which faced increasing amount of pollution due to the discharge of industrial effluents in the river and the efforts made  to solve the pollution problem.

The phenomenon of pollution started in the 1970s when Naroda, Odhav, Vatva and Narol on the eastern periphery of Ahmedabad city were promoted by the government. While there were zones for industries according to the type of waste generated, environmental considerations were overlooked and no provision was made for the safe disposal of industrial effluents. Most of the factories in the industrial estates were water intensive and all of them discharged effluents into the nearby Kharicut canal, which flows into the Khari river, a tributary of the Sabarmati. As the canal remained dry throughout the year, the government ignored its (mis)use.
