A sector-oriented approach to design and implement climate services helps uptake and use of the information provided. To deliver an effective climate service to the water sector, a clear understanding of the stakeholders and their particular needs is required.

Simultaneously, a “sector” is a wide definition, particularly when addressing the collection of professionals in, for instance, the water sector. Information at different time scales and levels of spatial and temporal aggregation is needed for different applications. IMPREX, an EU Horizon2020 project, has reevaluated and serviced a substantial number of water-related applications for European Climate Services by means of stakeholder inventories, and tailored pilot weather and climate applications. This includes evaluation of benefits, impacts on decision-making, and integration of different knowledge components necessary for adapting to extreme hydrological events. Many, sometimes surprising, user requests and results have been revealed. We computed benefits of using more precise hydro-meteorological information for reservoir inflow management of hydropower plants. We explored use of seasonal forecasts in agricultural water allocation schemes. We used high resolution precipitation forecasts to build a water treatment turbidity forecast and delved into vulnerability of the European economy to extreme weather events outside its borders. We developed a pre-operational probabilistic river level forecast for traffic and transportation on the Rhine and computed added value of using this information for reducing costs.

We will present key-findings, highlights and recommendations from IMPREX. Also a synthesis of the successes and lessons learned is given, by stratifying the experiences along different types of climate information (space/time scale) and levels of experience of the users. The session will actively engage the audience by using an interactive moderation and facilitation tool.
