Étude de perceptions et d'observations agricoles sur le réseau de haies emblématique des Alpilles : trajectoire d'un paysage en transition

Abstract : The territory of the Natural Park of Alpilles knows a sudden landscape transition by noting the disappearance of 28% of its linear hedges between 1955 and 2017. This evolution raises cross-cutting issues, questioning the ecological, cultural and agricultural organization of the territory. The hedge mesh of the Alpilles has the particularity of being composed of monospecific hedges of cypress windbreak, Provencal emblem. These hedges concern more than half of the mesh and are of agricultural origin. Excellent protection against the effects of the north wind, the mistral, the cypress hedge has allowed the intensification and diversification of agriculture on the territory of the Alpilles, territory under perfusion of s water of the Durance given the weak proportion of streams. The hedges disappearing, it was decided to go to meet the farmers to understand the future of this landscape.The hedge loses use, cultures diversify, the mesh loses legitimacy. However, with the contemporary issues of climate change and ecological awareness, the use of the hedge is migrating to address new issues. On the one hand, it is about coping with rising temperatures with a decrease in the availability of water resources. On the other hand, the ecological awareness of our society allows to highlight new uses of hedgerows, perceived as a functional biodiversity reserve for crops.The mutation of this iconic windbreak hedge landscape is ultimately closely linked with the perception and agricultural uses of the hedge. It is essential to raise awareness of the different services provided by these lines in order to cross agro-socio-ecological issues.
