IAHS-EGU 2014 Panta Rhei IWRM conference Bologna, Italy KMnotes130614 What is Panta Rhei? Panta Rhei is the name of the IAHS scientific decade 2013-2022. The purpose of Panta Rhei is to “reach an improved interpretation of the processes governing the water cycle by focusing on their changing dynamics in connection with rapidly changing human systems”. Why important? Mainly driven from a hydrological perspective, who are trying to be more inclusive esp of social sciences (working with social scientists). You have an opportunity to get involved in the themes and working groups now and to contribute to the current community vision paper. Key players? Apart from you, Alberto Montanari organised the conference and chaired an excellent session on the community vision paper, Hulpert Savenije (President of IAHS, Delft) and Günter Blöschl (EGU, Vienna). KEY THEMES/POINTS Need for greater levels of synthesis and what is required to enable it. Requirement for improved indicators, which will enable understanding and monitoring of catchments as social ecological systems linked with governance. Humans are not passive actors and the complex management systems we have built, need to be in our models, including human behaviour. How to move from responding to existing problematic situations to being more pre-emptive? Water systems designed in the past are often now not fit for purpose. Gunther closed the conference suggesting that Panta Rhei can help the development of coherent theory on the two-way interaction between society and water. INDIVIDUALS/TALKS (that I thought were good and/or important) Pieter van der Zaag (UNESCO-IHE) fascinating keynote on the need for bridging concepts and consensus across natural and social sciences as different epistemic communities see the same thing differently (we are sitting in local optima). Compared four different disciplines e.g. political geographers. Highlighted the importance of Norgard’s concept of coevolution. Günter Blöschl, (Vienna University of Technology, Austria), Tom Evans (Indiana University) and Peter Loucks (Cornell, US)(and others) stressed the need to learn across individual studies to advance our understanding of the two way interactions between society and water. Graham Jewitt (University of Kwazuli-Natal, SA) suggested for interested in how we train the next generation of interdisciplinary catchment scientists. Graham presented a triangle of that was required for improving catchments, with a focus on unpacking CoP. Tom Evans (Indiana University) in his keynote on governance, learning and complexity in water system made the case of the tight coupling between monitoring and governance (need robust governance indicators). Need more meta-analysis based on common coding across case-studies (he has been heavily influenced by Lin Ostrom’ framework) Peter Loucks (Cornell, US) in his keynote provided an overview of systems based approaches to water. If you model can do synthesis you will get a noble prize. Water has many dimensions and if we can understand these we can influence decision making. A challenge is that objectives change over time. Quentin Grafton (ANU) in his eye opening keynote on the economics of water desalination in Sydney. Decision influenced by what climate data you use (in terms of over what period). The decision to build the plant was more about politics than finances. Ezio Todini (Università di Bologna) in his keynote suggested we should communicate predictive knowledge and not predictive uncertainty to non-research stakeholders. Anthropogenic change on hydrology is interactive.
