Coordinated research management is crucial for the success of inter- and transdisciplinary research programs - such as Wings. A laissez-faire type of management, which hopes that the different parts of such programs grow together organically has not proven successful. Rather, the different parts have the tendency to diverge, making inter- and transdisciplinary integration at a later stage more difficult. The proposed project aims at enabling the realization of the program’s inter- and transdisciplinary ambitions by (1) fostering strategic collaborations across Eawag and beyond, (2) facilitating inter- and transdisciplinary integration – connotating a process of creating a coherent and comprehensive whole of the different parts being brought together – within and across the program, (3) producing a first scientific synthesis towards the end of Wings Phase II, and (4) facilitating open, reflexive and continuous discussions among the Wings team on inter- and transdisciplinary collaboration and integration in both theory and (daily) practice. The proposed project will build on and further develop the collaborative structures set up in Wings Phase I to effectively facilitate collaboration, integration and synthesis as work progresses. The project will strengthen Eawag’s capacity for inter- and transdisciplinary research, by fostering a long-term learning process among team members on ‘how to do’ inter- and transdisciplinary collaboration and integration and ‘how to do it differently’ in case forms of collaboration and/or means of integration prove to be little effective to exploit the programs’ full inter- and transdisciplinary potentials. Finally, it will allow for realigning, if necessary, inter- and transdisciplinary collaboration and/or integration and for drawing lessons learnt for future strategic research programs.
