“…We chose to compare these two cities because both have experienced strong population growth since the mid-twentieth century (Table 1), resulting in extensive expansion, mainly toward dispersed morphologies ( Fig. 1) into surrounding rural areas (Abrantes et al, 2010;Salvati et al, 2012). Thus, the challenge of farmland conversion governance is strong in both city-regions.…”

“…Par ailleurs, que soient mobilisés le registre de l'environnement ou la contestation des procédures de décision, c'est bien du cadre de vie dont il est question : les riverains cherchent à défendre leur environnement, qui leur semble menacé par la procédure qui se met en place, en s'appuyant sur les ressources offertes par le droit, quand il ne s'agit pas de manifestations ou de mobilisation des médias. Comme suggéré par la littérature (Abrantes et al, 2010 ;Pham et Kirat, op. cit.…”

“…The topography of the territories and coastal development policies have led to an imbalance in both the population and in the distribution of activities over the region, and hence to "coastalization" (the concentration of populations and activities along the coastline [9], which is characteristic of the Mediterranean basin). The region's demographic growth is concentrated in the major cities and their peripheral extensions, all of which are situated within 30 km of the coast [10]. On the coastal plain, the construction of housing and infrastructure, and the development of economic activity zones (which has increased with demographic growth), have led to significant pressure on land resources.…”

Abstract:In France, in the peri-urban context, urban sprawl dynamics are particularly strong with huge population growth as well as a land crisis. The increase and spreading of built-up areas from the city centre towards the periphery takes place to the detriment of natural and agricultural spaces. The conversion of land with agricultural potential is all the more worrying as it is usually irreversible. The French Ministry of Agriculture therefore needs reliable and repeatable spatial-temporal methods to locate and quantify loss of land at both local and national scales. The main objective of this study was to design a repeatable method to monitor land conversion characterized by artificial sprawl: (i) We used an object-based image analysis to extract artificial areas from satellite images; (ii) We built an artificial patch that consists of aggregating all the peripheral areas that characterize artificial areas. The "artificialized" patch concept is an innovative extension of the urban patch concept, but differs in the nature of its components and in the continuity distance applied; (iii) The diachronic analysis of artificial patch maps enables characterization of artificial sprawl. The method was applied at the scale of four departments (similar to provinces) along the coast of Languedoc-Roussillon, in the South of France, based on two satellite datasets, one acquired in 1996-1997 (Indian Remote Sensing) and the other in 2009 (RapidEye). In the four departments, we measured an increase in artificial areas of from 113,000 ha in 1997 to 133,000 ha in 2009, i.e., an 18% increase in 12 years. The package comes in the form of a 1/15,000 valid cartography, usable at the scale of a commune (the smallest territorial division used for administrative purposes in France) that can be adapted to departmental and regional scales. The method is reproducible in OPEN ACCESSRemote Sens. 2012, 4 405 homogenous spatial-temporal terms, so that it could be used periodically to assess changes in land conversion rates in France as a whole.
