Climate change and biodiversity loss are mounting threats to Australia’s water security. So we often hear calls for more dams. But is that the answer?
Our recent research reveals large dam projects are costly gambles with public money. They often fail to deliver promised economic benefits. They also have major environmental, financial and social impacts.
In New South Wales, some members of the Lower Lachlan River community were concerned about plans to expand Wyangala Dam. They first asked us in 2020 to investigate its full costs and benefits, with findings presented at a local workshop in 2022.
