Researchers in the Social and Human Sciences (SHS) investigating the sustainability of our modes of collective organization are faced with fundamental questions. Dialogue between the various disciplines within the SHS is unavoidable, as is exchange with researchers in the life sciences. Even if there currently exists a general consensus on the reality of a multidimensional ecological crisis (radical climate change, depletion of resources, loss of biodiversity…), the positioning of the social sciences researcher is more controversial. The aim of this conference is to give researchers in all areas of SHS (management sciences, economics, sociology, the philosophy of science, political science, law, psychology…) the opportunity to dialogue on these questions: what position should they adopt on the issue of sustainability? What is their role and what mission should they assign themselves?
