Dans le cadre du colloque&#160;Les d&#233;fis de d&#233;veloppement pour les villes et les r&#233;gions dans une Europe en mutation (5-7 juillet 2017, Ath&#232;nes, Gr&#232;ce), le LabEx ITEM (Innovation et territoires de montagne) organise&#160;une session sp&#233;ciale (session 18)&#160;intitul&#233;e : Trajectoires d&#8217;adaptation d&#8217;espaces de marge. Une approche comparative de contextes territoriaux vuln&#233;rablesArgumentaireCette session veut questionner les capacit&#233;s d&#8217;adaptation et les possibilit&#233;s d&#8217;&#233;volution des espaces p&#233;riph&#233;riques et de marge, en focalisant sur des contextes montagnards particuli&#232;rement affect&#233;s par les changements globaux tant dans leurs dimensions climatique qu&#8217;&#233;conomique. Ils ont de ce fait une valeur embl&#233;matique d&#8217;espaces-laboratoires du changement, et constituent des terrains d&#8217;&#233;tudes heuristiques pour la compr&#233;hension de l&#8217;&#233;volution des rapports &#224; l&#8217;environnement dans les dynamiques territoriales. Une forte charge imaginaire et symbolique, leurs atouts paysagers et ludiques, &#160;leur conf&#232;rent des atouts sp&#233;cifiques, qui valorisent aussi les m&#233;tropoles proches. Dans le m&#234;me temps, leur vuln&#233;rabilit&#233; &#233;conomique et environnementale conduit &#224; des mobilisations sociales et politiques o&#249;, entre projets d&#8217;&#233;quipements et d&#8217;urbanisation, injonctions &#224; la protection de l&#8217;environnement et exp&#233;rimentations alternatives, se confrontent nouvelles et anciennes territorialit&#233;s. Les espaces de montagne interrogent ainsi l&#8217;&#233;volution des rapports centres-p&#233;riph&#233;ries : quels nouveaux services rendus par les zones non-urbaines, comment les mesurer et les faire reconna&#238;tre, des relations de r&#233;ciprocit&#233; &#160;deviendraient-elles possibles, sous quelles conditions ? Ce contexte particulier renvoie plus largement &#224; des contextes territoriaux o&#249; l&#8217;articulation entre vuln&#233;rabilit&#233; environnementale et &#233;conomique et attractivit&#233; territoriale offre de nouvelles formes d&#8217;adaptation. Dans ces strat&#233;gies d&#8217;adaptation, comment jouent les facteurs environnementaux, aux c&#244;t&#233;s de l&#8217;organisation &#233;conomique ? Les am&#233;nit&#233;s environnementales, synonymes de cadre de vie, de paysage, contribuent-elles &#224; recomposer les processus de s&#233;gr&#233;gation socio spatiales jusqu&#8217;alors constat&#233;es ? R&#233;duisent-elles les in&#233;galit&#233;s sociales ? De m&#234;me, les d&#233;marches de planification territoriale, quels que soient l&#8217;&#233;chelle et le caract&#232;re contraignant ou non, int&#232;grent elles ces nouvelles relations villes-montagne ? Avec quelle vision de la durabilit&#233; du d&#233;veloppement ?&#160;Cette session est propos&#233;e par le Labex ITEM (Innovation et Territoires de Montagne) dont l&#8217;objet est l&#8217;analyse, via une approche pluridisciplinaire, du devenir des territoires de montagne confront&#233;s aux enjeux du changement global. Elle vise tout &#224; la fois une comparaison internationale sur ces espaces, une comparaison entre milieux diff&#233;rents, une &#233;valuation de l&#8217;importance de contextes territoriaux et environnementaux dans les trajectoires et formes de changement.&#160;Les communications propos&#233;es pourront donc rendre compte de travaux et de recherche men&#233;s sp&#233;cifiquement sur des espaces de montagne, avec des intensit&#233;s de lien &#224; la ville variables. Elles pourront &#233;galement porter sur d&#8217;autres types de territoires, littoraux ou marqu&#233;s pr&#233;f&#233;rentiellement par des processus de m&#233;tropolisation. Ceci permettra de mettre en perspective des contextes territoriaux vari&#233;s et ainsi, questionner la sp&#233;cificit&#233; de la montagne dans les formes d&#8217;adaptation et de r&#233;silience constat&#233;es et analys&#233;es. A-t-on un effet de milieu, avec quelle articulation entre id&#233;ologies, id&#233;alit&#233;s et &#233;cosyst&#232;mes, ou a contrario, les formes et modalit&#233;s d&#8217;adaptation des acteurs et des territoires ne montrent-elles que des d&#233;terminants structurels autres et &#224; d&#8217;autres &#233;chelles ?&#160;Modalit&#233;s de soumissionSoumettre un r&#233;sum&#233;L'appel &#224; communication est ouvert jusqu'au 1er mars 2017.sur le site de l&#8217;ASRDLF (http://asrdlf2017.com),&#160;en indiquant le num&#233;ro de session (18).CoordinationMarie-Christine Fourny, UMR Pacte, Universit&#233; Grenoble-Alpes,&#160;Emmanuelle George-Marcelpoil, Laboratoire DTM IRSTEA Grenoble,&#160;Kirsten Koop, UMR Pacte, Universit&#233; Grenoble-Alpes &#160; &#160;During 54th Annual Colloquium&#160;Cities and regions in a changing Europe: challenges and prospects,&#160;Athens (5-7 July 2017),&#160;LabEx ITEM (LabEx Innovation and Mountain Territories) organize&#160;a special session&#160;(session 18)&#160;called&#160;: &#160;Outlying areas&#8217; pathways of adaptation. A comparative approach of vulnerable territorial contexts.ArgumentThis session sets out to question how capable outlying areas are of adapting and their possibilities of developing over time, by focusing on mountainous contexts particularly affected by global climate and economic changes. As such they have a symbolic value as areas-laboratories of change, and represent heuristic study sites for understanding the change in the relationship with the environment and their role in territorial dynamics. Highly inspiring and symbolic, mountains' scenic landscapes and the recreational potential they harbour are very specific assets which also benefit nearby big cities. At the same time, their economic and environmental vulnerability brings about social and political forms of mobilisation where old territorial issues must be weighed against the new, between infrastructure and urban planning projects, environmental protection requirements and alternative pilot schemes. Mountain areas are thus mulling over the changes affecting centre-outlying area relationships: what new services are provided by non-urban zones, how can these be measured and promoted, should relationships of reciprocity become possible, and under what conditions? This specific context evokes the bigger picture of territorial contexts where the link between economic and environmental vulnerability and territorial appeal is offering up new forms of adaptation. In these adaptation strategies, what role do environmental factors play alongside economic organisation? Do environmental amenities &#8211; which could also be called living environments or landscapes &#8211; help to reconstruct the socio-spatial segregation processes observed to date? Do they reduce social inequalities? Likewise, irrespective of their scale and whether or not they are binding, do territorial planning strategies take these new city-mountain relationships on board? With what view taken of the sustainability of development?&#160;This session is being organised by the ITEM (Mountain Territories and Innovation) Labex (laboratory of excellence), whose purpose it is to analyse, through a multidisciplinary approach, the fate of mountain territories grappling with the issues of global change. It is aiming to present an international comparison of these areas, a comparison between different environments and an assessment of the significance of territorial and environmental contexts in the pathways and forms of change.&#160;Contributions submitted could therefore report on work and research conducted specifically on mountain areas, with closer or weaker ties with city areas. They could also look at other types of territory, on the coast or preferentially marked by metropolisation processes, in which large urban areas develop and interconnect further through population growth and expanding services. This will enable comparison of varied territorial contexts and therefore a perspective to be gained, raising questions over what is specific about the mountain in the forms of adaptation and resilience observed and analysed. Is there an environment effect, and if so, how do ideologies, idealities and ecosystems tie in with one another, or, on the other hand, do stakeholders' and territories' forms and processes of adaptation merely demonstrate other structural determinants and at other scales?&#160;This session sets out to question how capable marginal or peripheral regions are of adapting and their possibilities of developing over time, by focusing on mountainous contexts particularly affected by global climate and economic changes.
