WINTER MED promotes the transition from the current overexploitation of insular tourist destinations during the summer to an alternative, sustainable, all-year round use of these territories, by delivering a transnational strategy and the tools for changing and upgrading one of the key sectors of the Mediterranean area. The project is built on the potential of capitalisation: analysing, assembling, adapting and testing available tools and methodologies to deliver a transnational strategy for the development of all-year round sustainable and responsible tourism in Mediterranean island destinations.The partners co-construct integrated solutions to common challenges, focusing in the common interests, beyond and besides the dimensions usually associated to the competition between destinations in a global market. From this objective and approach stems the holistic intervention aligned and contributing to ICZM and MSP in the area.The final transnational strategy provides the tools for and the demonstration of the benefits of policy learning and evidence-based decision-making. The partnership gathers a group of institutions with recognised experience in EU projects and tourism in insular areas. Furthermore, their complementary capacities allow the deployment of the sequential work plan: from the analysis of previous results to its implementation and improvement towards mainstreaming the project conclusions and widening their integration into the different policy and economic levels
