What is Water4All actually about? What other research is going on in the framework of this call and the entire funding scheme? To answer these questions, the Water4All secretariat organised a 2-day kickoff meeting at the Spanish Ministry for Science and Innovation in Madrid, where our project had to be represented. Principal investigator Harald Sodemann was at this meeting for ISOSCAN. In addition to presentations of each individual of the 27 projects funded within this Water4All call, the European Commission was represented by two speakers that explained the framework for how the EU plans to adapt to a changing water cycle with climate change. The ISOSCAN presentation stimulated a quite lively discussion, including many questions about the citizen science approach. In addition to all other project representatives, several funding agencies were represented as well, and it was indeed useful to participate in this networking event, for example to connect with the Norwegian and Swedish-led projects ECCO and MEWS. The mid-term event may be organised in a hybrid format such that we could reduce our travel activity.
