Multipurpose hydropower reservoirs are regularly framed as water security and climate change solutions. Although multipurpose projects can and do deliver a range of water services, 'win-win' outcomes are not guaranteed. Emerging water and energy risks are altering the net benefits from operating reservoirs to deliver hydropower generation, water supply, flood control, or other purposes. This paper shows that new hydropower governance approaches are needed to efficiently and fairly reallocate water under risks. We demonstrate that dynamic water reallocation is fundamental to the resilience of multipurpose reservoir systems and examine three potential reforms: periodic relicensing, water tariffs, and hydropower sustainability performance bonds.

Climate change, over abstraction, pollution and questionable engineering-based paradigms are contributing to a state of crisis in water governance. This paper reports on preliminary research in Lake Baiyangdian catchment, China, which has the potential to realise more systemic and adaptive forms of water governance through development and use of a method that reframes water catchment management in the form of social learning. A cross-disciplinary research group worked together with multiple-department managers and stakeholder representatives within a purposefully designed ‘learning system’ to create an insipient social learning platform. The results demonstrate the potential to reframe water catchment management in Lake Baiyangdian so as to better address the questions: who should manage the water catchment and what in the catchment should be the focus of managing?
