The aim of the third SISA workshop is to bring together research insights and practical experiences in making agriculture more sustainable. The workshop will discuss these in-depth, seeking to contribute to more robust knowledge on how to stimulate transitions towards sustainable agro-food systems. The workshop will address a range of analytical methods, experiences and scientific insights of the main issues at stake in sustainability research and projects. Doing so, the meeting seeks to realize three main objectives, notably: • Compare and contrast the issues and analysis of multi-actor innovation process, R&D practices, governance and transformative policies in various European countries; • Provide input to rethinking government policies, socio-professional strategies and civic concerns to contribute to sustainability transitions in the agro-food systems on the basis of existing research and experiences; • Define the content and the agenda of the on-going SISA open consortium for further research and mission-oriented policy support.
