The HITTS project will develop 1 pilot experience of the Strategy developed in WG2 with different thematic focus in each country (1 in Spain, 1 in France and 1 in Portugal). All pilot actions will share common and other distinctive elements, depending on the characteristics of each territory, its potential and needs and the existence of a different national reference framework. Each territory will test common elements of the Strategy necessary to achieve the desired socio-economic development. In this regard, the common part tested by all partners will include the development of a participatory governance system (A3.1); design of an action plan translating the strategy into concrete measures (A3.2) and training for local actors (A3.3). The thematic pilot experience will be different in each territory: — Spain (PP1, PP2, PP3) – Readaptive Wealth Use Approach: promote, condition and adapt cultural and natural heritage to ensure universal access to certain identified elements or goods. — France (PP7, PP8) – Mobilisation of actors for the creation of tourist, artistic and cultural activities for the revitalisation of the cultural and natural heritage of a common protected area. — Portugal (PP5,PP6) – Readaptation of the natural heritage of the lizards and conditioning of the hiking routes in Montalegre. These actions will be very important for HITTS, as key and common elements of the strategy can be tested in real environments with their uniqueness and themes. The results obtained will serve to collect improvements to be integrated into the Strategy based on the aspects tested in the SUDOE territory.
