This issue of the park magazine is dedicated to the European Charter for Sustainable Tourism, an important goal, which was achieved following an articulated and complex process. The issue describes some of the stages of this path, also through the voice of the protagonists of the territory and the experts of Federparchi-Europarc, which is the authority in charge of the assessment. The magazine also takes an in-depth look at the potential of the ECST tool and the key role played by operators in the tourism field, to ensure that parks are truly a driver of social and economic development in communities.
