Climate change is expected to involve increasing climate variability. Can we manage our water resources while floods and droughts increase in frequency and severity without adding more storage space through building dams and other storage facilities?

Dams, surface, but also underground storage reservoirs are conventional means to reduce the dependability on the natural occurrence and availability of water. While these technical solutions are not without controversy storage facilities equipped with hydropower stations could even account for some GHG reduction. There is a need for an ideology free global assessment and recommendations for those regions where climate change is expected to manifest itself most viciously.
