Hitts faces the following challenges common to the SUDOE space: depopulation, ageing and the leakage of high value-added human resources; Lack of value for heritage, including artistic and cultural heritage, as a driver of eco-tourism; low level of adaptive reuse of heritage and lack of coordination and awareness of all local actors. Therefore, the main objective of HITTS is the valorisation of the cultural, natural and heritage singularities of the rural areas of SUDOE, based on the revitalisation of cultural and natural heritage, artistic creation and the development of public-private collaboration through innovative methodologies and tools to promote sustainable and ecological tourism. Hitts is an innovative project that aims to carry out transnational actions to promote sustainable tourism based on the valorisation of the cultural and natural heritage of the rural areas of the SUDOE space, mobilising and involving local actors and agents throughout the implementation of the project, encouraging the adaptive reuse of heritage based on artistic and cultural productions and the development of public-private strategies with the perspective of a renewed governance. The project will start with actions focused on the involvement of all actors in rural intervention areas (GT1) through the territorial laboratories. A participatory diagnosis will be developed by territory to evaluate endogenous heritage, cultural and artistic resources and 15 good practices will be detected. A common strategy will be designed for the innovative and sustainable socio-economic development of rural areas in the SUDOE (GT2) space, which will be the main realisation of the project, based on the touristic valorisation of its cultural and natural heritage. Finally, HITTS proposes the implementation of pilot actions of the strategy, adapted to the uniqueness, conditions and needs of each territory.
