[en] After an interview and a contribution of experts about the social-political and climate context within the perspective of the adaptation of French territories to climate change, a first set of contributions addresses, reports and comments several regional studies. They more particularly address knowledge and communication stakes, the scale to approach adaptation to climate change, an action plan for south-eastern France, an example of appropriation of results in Languedoc-Roussillon, the study of mutations related to climate change for a better adaptation, a prospective approach from sequential scenarios to recommendations for action, an attempt to assess costs of adaptation to climate change in three sectors in Normandy (agriculture, health and tourism), and a decision aid for the first assessments of adaptation costs. Another set of contributions addresses the necessity of a debate on the stakes of adaptation for territories: articulation of territorial scales, passage from the awareness of vulnerability to adaptation actions, how to ensure an efficient taking into account of adaptation to climate change in public policies
