Bangladesh is known as the land of rivers and flooding, despite almost all of its water originating outside the territory. The fact that 80% of rivers that flow through Bangladesh have their sources in a neighbouring country, can make access to freshwater in Bangladesh fraught. And the country’s fast-growing cities and farms – and the warming global climate – are turning up the pressure.
In a recent analysis, my colleagues and I found that four out of the ten rivers that flow through Bangladesh have failed to meet a set of conditions known as their “safe operating space”, meaning that the flow of water in these rivers is below the minimum necessary to sustain the social-ecological systems that rely on them. These rivers included the Ganges and Old Brahmaputra, as well as Gorai and Halda.
