URL is mobilized in the face of the current pandemic context through the dissemination of an AAP_2020. It is indeed crucial to provide analyzes of the past crisis and to anticipate those to come, whether directly or indirectly linked to the new coronavirus. The underlying idea of this approach is to feed multidisciplinary work on risks and crises in urban areas, on the basis of the Covid-19 crisis understood in a deliberately broad sense. The challenge is to enrich the work of prevention and anticipation of an urban crisis in the light of the current analysis. The call therefore aims at the same time: Feedback on what has been played out (technological aspects with digital applications, organizational and political aspects of crisis management, both at government and territorial level, scientific controversies, textual analyzes and video, illustrations, etc.); Research and development of reflections and solutions to the health, economic, social, political, environmental issues (in particular pollution, waste, etc.) generated by this crisis, its management and the way in which these have been understood by the populations. The call is open continuously until September 7, 2020.
