ÉTALEMENT URBAIN, DYNAMIQUES AGRICOLES ET POLITIQUES PERIURBAINES UNE ANALYSE SPATIALE DU LANGUEDOC-ROUSSILLON ET DU PORTUGAL

N° ISBN - 978-2-7380-1284-5International audienceFor almost 40 years cities' peripheries and the coastal areas of Languedoc-Roussillon in France and of Portugal have been known important urban dynamics that affect natural spaces, and most particularly the agricultural areas. These dynamics are due to periurbanization, i.e. the increase of urban sprawl and of spatial fragmentation, thus contributing to important decline of the agriculture land. These dynamics are nowadays considered in spatial policies and planning at different scales by developing, among others, the role of agriculture as a way to deal with urban sprawl. This paper is developed in three steps: a) the spatial analysis of the urban dynamics, specially the mutations of the agriculture lands of Languedoc-Roussillon and of Portugal; b) the analysis of spatial policies and planning at different scales, and of how they are dealing with urban dynamics; c) the analysis of two different local projects – one in Languedoc-Roussillon (Lunel) and the other one in Portugal (Guimarães) – that are trying to enhance the periurban agriculture as a way to combat urban sprawl, thus promoting a more urban and periurban sustainable development
