In July 2023, the selection process for participants in the Knowledge Brokerage programme, implemented within the framework of SSH CENTRE, was concluded. Overall, 185 applications have been received between 20 April and 3 July, i.e., the period in which the Call for Applications was open. They have been then analysed, leading to a selection of 30 researchers. The participants, who will participate in a dedicated training course in November, will be organised into six different teams, each of which will work in collaboration with a European city administration to conduct a knowledge brokerage initiative on specific topics related to environmental transitions. The involved cities are Valencia (Spain), Grenoble (France), Arnhem (The Netherlands), Rijeka (Croatia), Porto (Portugal), and Čačak (Serbia). The selection process has been conducted under WP3, led by K&I.
