Transformative science in the digital space requires new knowledge, attitudes and skills. Co-creation, especially in a transdisciplinary environment, is not easily converted from physical meetings to an online format. Rather, it requires a conscious use of digital tools and a critical reflection about their influence on our interactions: how does the online environment influence communication? How can participation and inclusion be enabled, contributive fairness be fostered and trust be created in an online setting? A research team at the Centre for Development and Environment (CDE), University of Bern, developed guidelines based on experiences of researchers and lecturers at CDE during the COVID crisis, with a view to offering hands-on suggestions for online practice.
