In times of the "Great Transformation" in the "Anthropocene" the longing for comprehensive scientific answers to the socio-ecological crises is great. In research, the focus is strongly on influencing future developments in the sense of the concept of sustainability. The contributions in this anthology approach central themes of this concept, time/s – nature/s – spaces – inter- and transdisciplinarity, partly in essayistic, partly in academic ways. One focus is on the category (re)productivity, which has been theoretically elaborated by Adelheid Biesecker and Sabine Hofmeister and which is further developed from different theoretical and thematic perspectives.
