Many marginal mountain areas need innovative strategies and actions to tackle their depopulation and improve the quality of life of their inhabitants.  "Montagne Vitali" is an experimental project aimed at creating a strategic planning path to support small peripheral mountain areas. The whole Tre Ville community (Province of Trento) is involved in rethinking its future in a shared and ecologically sustainable way, starting from the definition of local opportunities and issues. The path foresees the start of the first concrete medium-long term projects and the definition of an all-round perspective for the regeneration and development of the territory.
