The topical renewal of short food chains is examined here from a national framework showing a limited growth, then from a regional framework (in ‘Midi-Pyrénées’ region) about two kinds of collective organisations participating in this renewing. The first, Community Supported Agriculture, knows a rapid success in the region, booming from 1 association in 2003 to 101 in 2007 then to 123 in 2009. The second, Producers Collective Shop, is older and concerns more farmers (700 to 800). Their development questions researchers and professionals about regional planning and about involvement conditions in these networks for local producers and consumers. We propose here to summer a study case realised in ‘Midi-Pyrénées’ region, based on cartographic description and qualitative analysis of the functioning and the current sense of these initiatives.
