ICOLD President answers Oxford misleading study

Yes, we need to build more large dams for water storage and energy for sustainable development!



Recently a study named “Should we build more large dams? The actual costs of hydropower megaproject development”, authored by Atif Ansar et al. has been released by the Said business school of the Oxford University.
