Thus, the integration of these alternative approaches into science aims at critically examining existing thought structures and methods along the question to what extent our conceptual tools can already theorize “alternative sustainabilities” and to what extent theories can be further developed along new categories or new approaches can and must be created. Here, interdisciplinary dialogue is crucial. In the long run, this will allow us to include a broader spectrum of lived realities in our research and teaching. While most of the colleagues in the group have a social science background, the expansion of the interdisciplinary dialogue should especially involve colleagues from the natural and life sciences. “Alternative” approaches to sustainability should be discussed in particular in dialogue with colleagues from science and practice in the Global South, in order to critically rethink sustainability and its implementation in glocal contexts from there. Many colleagues who are already involved in the group have strong collaborations in this area, which we would like to integrate. We also welcome SDG Fellows from the University of Bonn who are interested in joining our group. During their stay, they can temporarily collaborate with us, which we can gladly extend beyond the research stay.
