A vital part of the research project “Produktiv. Nachhaltig. Lebendig. Grüne Finger für eine klimaresiliente Stadt” are walks with different groups of people through Osnabrücks so called “Green Fingers”. On May 18 members of the “Bürgerbeirat” walked the green finger Sandbachtal and discussed perceptions, identified relevant questions and found ideas for the future of one of these important green structures. The project that is funded by the Federal Ministry of Education and Research (BMBF) can be seen as transformative science: The goal is not only to do research on transformation processes but to actively intervene in these processes by involving change agents in the process of research.
