The CNRS, through its Mission for Transversal and Interdisciplinary Initiatives, wishes to bring together the research potential of its teams around new emerging questions that will advance upstream fields of knowledge through interdisciplinary approaches. It has decided to launch a call for projects in 2022 entitled Participatory sciences in an interdisciplinary context. The aim of this call is to support research projects seeking to develop innovative participatory approaches (methodologies, instrumentation, questions, etc.) in an interdisciplinary context.
