European Cultural Heritage Strategy for the 21 st century „ Page 15 Chapter 4 Three priority components and four interfaces (areas of convergence) The strategy is based on three components: 1. The “social” component harnesses the assets of heritage in order to promote diversity, the empowerment of heritage communities and participatory governance. 2. The “territorial and economic development” component seeks to strengthen the contribution of heritage to sustainable development, based on local resources, tourism and employment. 3. The “knowledge and education” component focuses, through heritage, on education, research and life- long training issues, by establishing heritage knowledge centres and centres for training in heritage trades and professions, by means of appropriate teaching, training and research programmes. — These “components” interact in four areas of convergence: between the social component and the territorial and economic development component; between the territorial and economic development com- ponent and the knowledge and education component, between the knowledge and education component and the social component, and lastly, between all three components. — The overall consistency and specific nature of this strategy derive from the balance between the various components and their areas of convergence.
