Problématique et enjeux de la (re-)conquête d'espaces agricoles sur des espaces forestiers en région Provence Alpes Côte d'Azur. Étude préliminaire et premiers éléments d'analyse

Abstract

In the Provence Alpes Côte d'Azur region (France), some forest lands are converted to agricultural use, in particular in the wine-growing sector. In this region agricultural lands have to cope with urbanization and agricultural land abandonment. But this trend raises the question of natural and forest lands preservation. The issue is also to understand the conditions of these changes in land use. We carried out an exploratory study in order to quantify this evolution and provide information on the agriculture and forest stakes. This work was based on a bibliographic study and some interviews among local stakeholders. We also conducted a more precise study in the Var department using the CRIGE-PACA database to quantify the changes in land use regarding vineyards and forests (conversion of forest land to vineyards and vice-versa) between 2006 and 2014. We showed that the surfaces of forest lands to vineyards was very small. The requests for authorization to clear forest land often concerned plots which were formerly cultivated. However the context could accelerate this process, especially due to outside investors entering the wine-growing sector as well as the surface growth of som AOC/AOP, and the strong willingness of agricultural organizations to develop the wine-growing sector and more widely the agricultural sector. A more comprehensive study will be needed using spatial data to locate the impacted territories and assess the possible effects on forests. / En région Provence-Alpes-Côte d'Azur (France), des terres sont récupérées sur des espaces forestiers par des agriculteurs, particulièrement dans le secteur viticole. Dans une région où les espaces agricoles peinent à se maintenir face au développement urbain et à la déprise, cette tendance pose cependant la question de la préservation des espaces naturels et forestiers et des conditions dans lesquelles s'effectuent ces changements d'occupation du sol (lieu, superficie et types de forêts concernées, projets de valorisation de ces espaces...). Nous avons réalisé une étude exploratoire visant à quantifier cette évolution et à en préciser les enjeux pour l'agriculture et pour les espaces forestiers. Ce travail a été conduit à partir de la bibliographie existante et d'entretiens avec quelques acteurs du territoire. Un travail plus précis a été réalisé sur le département du Var, pour lequel nous avons utilisé des bases de données du CRIGE-PACA pour quantifier les transformations d'occupation du sol concernant la viticulture et la forêt (transformation de forêts en vignobles, et vice versa) entre 2006 et 2014. Les analyses montrent que les superficies de forêts converties en vignobles aux dépens d'espaces forestiers ont été très limitées au cours de la période étudiée. Les demandes de défrichement concernent souvent des parcelles anciennement cultivées. Cependant certains éléments de contexte pourraient conduire à une accélération de cette tendance, notamment l'entrée d'investisseurs extérieurs au secteur viticole apportant des capitaux importants et souhaitant les valoriser, l'extension des aires d'appellations de certaines AOC/AOP, et la volonté affirmée des organisations professionnelles agricoles de développer le secteur viticole provençal et plus largement l'agriculture. Le travail réalisé devra être poursuivi par des études spatialisées permettant de localiser les territoires impactés (ou pouvant être impactés) par cette tendance et d'évaluer les effets possibles sur les forêts concernées.
