Abstract

The subject of this article is the analysis of the interaction between urban Growth and the existence of a suburban quality Vineyard. Locations with natural characteristics, such as vineyard, are thought to be attractive residential and industrial locations. Suburban agriculture, which has to be explained, endures strong pressures from suburban development. Different land markets (agricultural and suburban) are mix up which drive to a substitution of suburban land use to agricultural ones. The general consequences are well known: a decrease in cultivate areas; a scattered development which increases urban sprawl; a rarefaction of available land which limits the probability of reorganization with rising land prices. The question is challenged in the case of high quality Vineyard, in Bordeaux, where some wine properties are still located in the urbanized area: profits released by vineyard exploitation are sufficient to cover the profits released by urban development. Thus, the high added value Bordeaux vineyard resists to urban pressure. We will try to explain why some wine parcels of land are converted in urban use (industrial or residential land use) whereas some others resist. If the agricultural urban land conversion is a traditional topic in spatial economics, studies on the interaction between urban growth and a suburban quality vineyard are very scared.

Our approach will consider determinants of household and firms localizations before being interested in their impacts on the probability of parcels conversion using a multinomial Logistic model. We applied a spatial logistic model to determine factors influencing land use change in the Bordeaux exurban area, France, from 2000 to 2007 using observations of land characteristics. Industrial use is also introduced as a competitor to the vineyard parcels that are located in periurban areas. Taking into account the industrial logic completely changes the nature of

what can be achieved. Geographical location as highlighted by the accessibility variables has an extremely important weight in understanding the phenomenon of industrial conversion. The residential conversion factors always do not light the mechanisms of conversion into industrial, the variable of accessibility explaining substitution of this last use. This model could be used to project land use change and thus serve as a valuable tool for county and city planners.

Resume

Le periurbain est soumis a des conflits d'usages : le developpement economique et l'accueil de population relevent d'autres logiques que celle de l'occupation du territoire par l'agriculture. Cette concurrence se traduit par des conversions de parcelles viticoles en industriel ou en residentiel. On est alors amene a s'interroger sur les determinants de conversion de ces deux usages. Notre approche considerera les determinants des localisations des menages et entreprises avant de s'interesser a leurs impacts sur la probabilite de conversion des parcelles a l'aide d'un modele Logistique multinomial. Les facteurs de conversion residentielle n'eclairent pas toujours les mecanismes de conversion en zone industrielle, la variable d'accessibitite expliquant la substitution de ce demier usage.

Introduction

L'evolution de ces dernieres annees tant dans le systeme productif que dans les modes de consommation a entraine de profonds changements dans la dynamique de spatialisation des hommes et des activites. L'etalement constant des agglomerations urbaines sur leur peripherie resulte aussi bien du choix des menages en quete d'une meilleure qualite de vie que des comportements des entreprises qui recherchent des terrains d'implantation plus vastes, mieux desservis et a moindre cout.

Le periurbain (1) est donc un espace rural au sens ou l'essentiel des sols y sont encore dedies a des activites productives agricoles ; mais c'est egalement, et de plus en plus, un espace urbain au sens ou la majorite de la population active qui y habite travaille dans une ville, en effectuant des migrations alternantes. …
