A l&rsquo;initiative du Carrefour des M&eacute;tiers du D&eacute;veloppement Territorial, un collectif compos&eacute; de diff&eacute;rents acteurs issus du terrain et du milieu acad&eacute;mique s&rsquo;attache depuis 2020 &agrave; explorer cette hypoth&egrave;se selon trois axes&nbsp;: <span style="color:black">le sens et les modes d&rsquo;appropriation des enjeux &eacute;cologiques par les citoyens&nbsp;;<b> </b>le renouvellement des pratiques et des m&eacute;thodes de l&rsquo;ing&eacute;nierie territoriale&nbsp;; et la n&eacute;cessit&eacute; de transformation des modalit&eacute;s de l&rsquo;action publique.

However, locally, many actions initiated by professionals and citizens are part of a transition process. Our hypothesis is that they contribute to redefining the modes of operation and governance for social and community workers around new issues, and particularly the emerging paradigm of the &lsquo;ecological commons&rsquo;. Following an initiative by the &lsquo;Carrefour des M&eacute;tiers du D&eacute;veloppement Territorial&rsquo; in 2020, a group composed of various actors from the field and the academic world has been exploring this hypothesis along three axes: the meaning and the modes of appropriation of ecological issues by citizens; the renewal of practices and methods of community intervention; and the necessary transformation of public intervention. This contribution attempts to shed light on the link between social intervention and transition, and summarises the initial results of our work.</span></span></span></span></p>
