Industries got a whacking yesterday as experts and environmentalists maintained that rivers around Dhaka are getting polluted wholesale by industrial waste. Even industries with effluent treatment plants do not run those facilities.

The 20-year study report on status of groundwater arsenic contamination in West Bengal by Jadavpur University, based on the analysis of water samples from tube wells in all 19 districts of West Bengal. Groundwater in nine highly affected districts had arsenic at concentrations of 300 lg/L and above.

Building real cooperation on transboundary waters is always a lengthy and complex journey. Embracing cooperation is no simple task for a nation state, not least because of the perceived costs of the erosion of sovereignty, however small that erosion might be. While there are many examples of where cooperation is non-existent or weak, there are also examples of robust cooperation.

Washington: The flow of water in the world

Rivers in some of the world's most populated regions are losing water, many because of climate change, researchers reported on Tuesday.

Affected rivers include the Yellow River in northern China, the Ganges in India, the Niger in West Africa, and the Colorado in the southwestern United States.

Rivers in some of the world's most populous regions are losing water, according to a new comprehensive study of global stream flow. The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate change. The process could potentially threaten future supplies of food and water.
