Prospective studies on country space undertaken by the DATAR points out the environmental functions of country space as well as its residential role or leisure; its sets back country space at the centre of sustainable development policies, all the more that new space shaping gives birth to new contradictions and environmental pressures Middle mountains backgrounds are specifically facing contradictory pressures between, on the one hand, protection of rural amenities and countryside viewed as a sign of major local identity , and on the other hand the rise in mobility constraints resulting from economic growth and functional organization of country space. Meanwhile, the Grenelle environmental summit, the bill concerning solidarity and urban renewal (SRU), policies pro-sustainable development, new social trends, all these factors lead to new environmental practices. Mastering mobility is a part of this problem; more and more routes sharing practices tend to reduce the use of private cars If sustainable development offers a new framework towards new car practices which could, in theory, help master mobility , it has not, up to now, succeeded in distinguishing itself from or challenging the economical context which implies increasing mobility while fostering hopes in a future "green growth".Worldwide crisis 2008-2009 –analysed through two of its consequences, the slowing pace of growth and the rising costs linked to transports – is analysed in opposition to eco-citizenship (here, "ecomobility") in terms of choice or constraints. In this respect, how do household behaviours interact between the economic reorganization of commuting and transports and the new environmental awareness ? Have the spatial and social features (and regional identities) an impact on speeches and practices?The analysis, focusing on a specific territory, will be based on data about motivations, income, environmental awareness and access to education on sustainable development. This questioning brings significant lights on the relations between individual practices, explicit or implicit ideologies of sustainable development confronted to the economic context. It also raises the issue of links between the viewpoints of protagonists, the education to sustainable development in and outside school and the identity components of territories. The impact of "ecomobile" practices on environment and territories enables to finalize the outlook. The contribution will span four folds: Economic standpoint of sustainable development, Impact on country territories an identity challenges, Case analysis: crisis & eco-citizenship behaviour adaptation in carpooling
