On 24th and 25th November 2021 ACTION held its final conference in collaboration with the EU-Citizen.Science project. The future of citizen science: sharing experiences from the European community was a great opportunity for reciprocal learning and for meeting new persons. More than 160 persons participated: we wish to thank them all! A special thank also to the speakers (more than 30), the collogues that showcased their work in the virtual booths (more than 20) and to StickyDot for supporting the organization and the facilitation of this successful event.
