The “vallean” experimental approach aims to broaden the partnership and build a project on a coherent perimeter, allowing, in particular, the territories to develop their specificities and reduce their dependence on snow products; it received joint support from the Region, the State and the European Union over the period 2007-2013. Two years of transition were funded in 2014 and 2015. In 2014, in order to refine and capitalise on the results achieved, to allow the consolidated balance of actions and programmes implemented in the valley areas, and to imagine collective perspectives for the intervention of the future POIA 2014-2020. In 2015 to apply for future programming and to draw up the action plan 2016-2018. It is for SMAEMV to create favourable conditions in order to carry out the 2016-2018 action plan for the valley area of the Mont-Ventoux Regional Natural Park Project.
