The second international congress organized by the ARCh research unit will take place in Liège on 4 and 5 December 2025. The event will focus on the concept of polycrisis, the interwoven health, ecological, economic, social and political crises that reshape individual and collective reference points. The first day will address interdisciplinary perspectives on polycrisis, while the second will examine its clinical implications. The program includes keynote lectures, symposia, oral communications and clinical workshops. The congress aims to understand how practices, norms and identities evolve in times of polycrisis and how clinical work can respond to these transformations.
