<p>La recomposition des &eacute;cosyst&egrave;mes locaux de la Nouvelle-Aquitaine (fusion r&eacute;cente des ex-r&eacute;gions d&rsquo;Aquitaine, du Limousin et du Poitou-Charentes) a conduit les parties-prenantes &agrave; se r&eacute;inventer. <span style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">La r&eacute;gion s&rsquo;inscrit dans la n&eacute;cessit&eacute; d&rsquo;obtenir une taille &eacute;conomique critique dans un environnement mondialis&eacute;.

The region is part of the need to achieve a critical economic size in a globalized environment. Paradoxically, it also takes the risk of losing proximity to sustainably transform its local ecosystems (in the sense of Tansley, 1933; Moore, 1993; and more recently Koenig, 2012). One of the transformative solutions has been to digitize the act of donation in order to perpetuate the local embedding of socio-economic actors. The founding works of Mauss (1924), supported by Godbout (2004) and Caill&eacute; (2004), allow us to approach the socio-economic role in the act of giving. Thus, the digitalisation of relations between donors and organizations could tend to a loss of socio-economic proximity: numerous studies have demonstrated this risk (for example: Degryse, 2016 and Delahaye, 2019). However, the creation of a digital and regionalized crowdfunding platform in Nouvelle Aquitaine has brought up communities of citizens (to date, 70% of citizen-donors of this platform live within 70 kilometers of the holders of funded projects). Digitalisation is done to the benefit of a territory and not vice versa. Can this digitalised relationship paradoxically transform the recomposition of local ecosystems in Nouvelle Aquitaine over the long term</span></span> ?</p>
