A poster of the PROGNOS project was presented at a Water JPI workshop on “emerging pollutants, including pathogens”. The workshop was held at the Federal Ministry of Agriculture, Forestry, Environment and Water Management in Vienna, Austria, on the 30th November 2016. Participants were from projects funded by the Water JPI Pilot Call, the Water JPI WaterWorks 2014 Call, FP7, H2020 and national programmes. The purpose of the workshop was, among other things, to foster exchange among on-going projects and to consider opportunities for collaboration. In addition to presenting PROGNOS objectives, innovations and benefits, PROGNOS members suggested the following opportunities for collaboration with: Water JPI projects reliant on weather forecast information; climate JPI projects involving water quality; and, the Inter-Sectoral Impact Model Inter-comparison Project.
