Join us as we explore the transformative potential of Citizen Science in shaping the future of research and innovation in Europe and beyond. The webinar is organized within the scope of the PolSCA Horizon Webinars series, targeting research managers, project administrators, and researchers operating in Poland. Its goal is to enhance understanding of citizen engagement, the multi-actor approach, and social readiness concepts in the context of the second Strategic Plan for the Horizon Europe program, upcoming calls within the Work Programmes 2025, and the increasing importance of citizen science in R&D projects. Citizen Science, endorsed by the European Commission and encapsulated within the Horizon Europe programme, represents a paradigm shift in research and development. It champions a multi-actor approach, inviting citizens to actively participate in scientific endeavors, from data collection to analysis, thus democratizing the scientific process. Within the framework of Horizon Europe, Citizen Science serves as a catalyst for social readiness, fostering inclusivity, transparency, and trust in research and innovation.
