<p><strong>R&eacute;sum&eacute; :</strong></p> <p>Suivre l&rsquo;invitation de Bruno Latour &agrave; devenir terrestre, recouvre un processus d&rsquo;enqu&ecirc;te complexe, par lequel on sonde tout ce qui lie chacun.e aux autres vivants et aux mati&egrave;res terrestres. Les enchev&ecirc;trements sont potentiellement infinis, et il convient sans doute de privil&eacute;gier des recherches men&eacute;es &agrave; plusieurs, avec lesquels nous vivons en interd&eacute;pendance plus ou moins &eacute;troite. Cet article revient sur trois dispositifs esth&eacute;tiques qui entreprennent de telles enqu&ecirc;tes, en mettant les corps &agrave; l&rsquo;&eacute;preuve du sensible, des autres corps et des environnements. Tandis que les ateliers <em>How to be terrestrial</em> s&rsquo;adressent &agrave; chacun.e, ancr&eacute;.e dans son lieu de vie, les ateliers <em>O&ugrave; atterrir</em>, initi&eacute;s par le collectif du m&ecirc;me nom fond&eacute; par Latour, rassemblent les habitants d&rsquo;une localit&eacute; dans une aventure commune. Enfin, le mouvement des ZO&Ouml;P invite les membres d&rsquo;une institution &agrave; se ressaisir de tout ce qui constitue leur &eacute;tablissement de rattachement, puis &agrave; en imaginer un devenir plus &eacute;cologique. A la diff&eacute;rence des deux autres formes esth&eacute;tiques, les artistes fondateurs de ZO&Ouml;P invitent les membres &agrave; d&eacute;passer le cadre de l&rsquo;enqu&ecirc;te sensible et sp&eacute;culative, pour en imaginer des cons&eacute;quences pragmatiques, et int&eacute;grer les principes du devenir &eacute;cologique dans les statuts de l&rsquo;institution.</p> <p><strong>Abstract :</strong></p> <p>Following Bruno Latour&#39;s invitation to become terrestrial involves a complex process of investigation: it aims at looking for everything that links each of us to other living beings and to terrestrial matter. As we may not be able to list all the interdependencies supporting our lives, we should undoubtedly give priority to research carried out by several people, with whom we live in more or less close interdependence. This article looks at three aesthetic devices that undertake such investigations, putting bodies to the test of the sensible, of other bodies and environments. While the <i>How to be terrestrial</i> workshops address each individual, anchored in his or her place of life, the <i>O&ugrave; atterrir</i> workshops, initiated by the collective of the same name founded by Latour, bring together the inhabitants of a locality in a shared adventure. Thirdly, the ZO&Ouml;P movement invites members of an institution to take hold of everything that makes up their establishment, then imagine a more ecological future for it. Unlike the other two aesthetic forms, ZO&Ouml;P&#39;s founding artists invite members to go beyond sensitive, speculative inquiry and imagine pragmatic consequences, integrating the principles of ecological becoming into the institution&#39;s statutes.</p>
