"From the fields surrounded by hedges in Vendee to the outskirts of the city of nantes, the sevre valley offers various types of country-sides which have been diversely affected and over run by the expending city during these last twenty years. An analysis of the contemporary changes of eleven communes composed of densely populated wine growing areas, the urban agglomeration which comes from the joining together of rural communes around an old city center, the pastures of the plateau where the river has caused industry to develop has allowed two types of studies to emerge in the town and countryside planning : the urban spread and the protection of the environment. The agglomeration of Nantes and the recent phenomenon of urban exodus, the attraction exercised on the rural areas by the new town of Clisson are the two principal motives of the residential development of these communes which have become a conflict between the logic of the town people and country dwellers. A new balance can come from a coherent policy of planning brought to life by the voluntary coordination of everybody engaged in the life of the valley to promode the emergence of a harmonious countryside." . .

"Des bocages vend\u00E9ens aux marges de l\u2019agglom\u00E9ration nantaise, la vall\u00E9e de la s\u00E8vre offre de multiples paysages ayant subi diversement la dynamique urbaine durant ces 20 derni\u00E8res ann\u00E9es. L'analyse des mutations contemporaines de 11 communes, rassemblant : des campagnes viticoles dens\u00E9ment peupl\u00E9es, une agglom\u00E9ration urbaine n\u00E9e de l'amalgame de communes rurales autour d'un vieux centre urbain, des plateaux bocagers ou la rivi\u00E8re a cr\u00E9e un sillon industriel, permet d'allier deux th\u00E8mes d\u2019\u00E9tude majeurs de l\u2019am\u00E9nagement : l\u2019\u00E9talement urbain et la protection de l'environnement. la pr\u00E9sence de l\u2019agglom\u00E9ration nantaise et le ph\u00E9nom\u00E8ne r\u00E9cent d'exode urbain, l'attraction exerc\u00E9e sur les campagnes par le pole urbain de Clisson sont les deux principaux moteurs du d\u00E9veloppement r\u00E9sidentiel de ces communes devenues le th\u00E9\u00E2tre de conflits entre la logique des citadins et celle des ruraux. Un nouvel \u00E9quilibre peut na\u00EEtre d'une politique coh\u00E9rente d\u2019am\u00E9nagement, anim\u00E9e d'une volont\u00E9 de coordination des actions engag\u00E9es le long de la vall\u00E9e pour favoriser l\u2019\u00E9mergence d'un paysage harmonieux." . .
