The water sector needs improved climate prediction and downscaling based on consistent grounds (IPCC 5th Assessment Report, 2013). There is also a need for near future weather scenarios and anticipation of their impacts in the water cycle together with risk management strategies. BINGO will provide demand-driven solutions for a number of specific climate-related challenges in particular for highly vulnerable water resources of strategic importance. Water managers and other stakeholders will then be provided with information on specific climate scenarios at the space/time resolution fitting their needs, enabling them to act at various geographical levels (local, regional and European). BINGO aims at reducing the uncertainty of climate predictions and developing response strategies to help society manage that uncertainty. An innovative approach consists of enrolling end-users from the start, identifying specific vulnerabilities, needs and concerns about future climate. BINGO is built around 7 research sites in Northern and Southern Europe, covering a representative range of climatic conditions as well as combinations of water systems and water pressures. They illustrate a variety of water cycles at local/regional scales in Europe over various timescales, as well as common problems, including floods and droughts; water quality pressured by CSO, agriculture and competing demands for water (urban/tourism; agriculture/food security; hydropower). To guarantee sound management strategies for future weather challenges, BINGO will develop and validate all solutions built by strong dynamic interaction of researchers with end-users and decision makers throughout the project. By creating such knowledge alliances, water managers and other stakeholders can share awareness of climate challenges, thus increasing the possibilities of collaboration in order to manage and better cope with future climate challenges.
