The INCULTUM project is based on a participatory approach where local communities and stakeholders play a direct and important role in the implementation of pilot actions. The ratio behind their involvement is to promote a positive impact of participatory models and avoiding negative effects of tourism for social relationships, local cultural heritage, or landscape preservation. Therefore, this report aims to create a solid foundation for the implementation of tasks in WP4. It is directly related to Task 4.1 In-depth analysis of participatory models. This report defines the key terms of participatory models in culture, tourism, and sustainable development, based on literature review, knowledge, and experience from previous empirical studies and implemented research projects.
