Participatory approaches and citizen science are more and more commonly used to address multiple scientific questions and, at the same time, exploit the potential of directly involving stakeholders and citizens. This enhances research dissemination and favors a more effective innovation pipeline multiplying the societal impact of scientific research. Indeed, worldwide scientists are increasingly engaged with open science, open innovation, and open-to-the-world principles. A main aspect of the success of citizen science is also the opportunity of taking advantage of cutting-edge digital technologies, to make science and innovation more collaborative and global. Open Science and Participatory research represent innovative ways to perform scientific research and processes based on cooperative work and new approaches to disseminate and share knowledge using digital technologies and new collaborative tools. Participatory and Citizen Science Initiatives in the Research Area are incredibly increasing in the last five years and many projects in plant and animal sciences are nowadays exploiting the potential of exploring participatory and citizen science, particularly in biodiversity conservation and crop improvement. This workshop will give the opportunity to keynote scientists and projects to illustrate the Participatory and Citizen Science experiments they are putting in place and highlight the genomics contributions in agriculture, for plants and animal conservation, and for agroecological sustainability.
