Goal and objectives of the dissertationGoalThe goal of the doctoral thesis is to analyze the tourist use of the historic city and how this process affects to urban heritage in two cities from the British and Mediterranean contexts, namely Plymouth and Malaga.Objectives* To analyse common and different aspects in heritage preservation and management in Europe, focusing on the British and Spanish models.* To examine how the heritage framework has evolved in selected cases and which is the current framework in relation to legislation and the role of administrations involved.* To study the historic evolution of urban tourism in both cities and the current relevance of tourism-related activities.* To analyse the different stakeholders and initiatives affecting the tourist use of the historic city in both cases, dividing them into four aspects: heritage and culture, tourism, urban planning and economy.* To compare how both cities compete in bidding for major events, regenerating their waterfront and developing creative neighbourhoods.* To develop strategies and proposals to achieve a better balance in the tourist use of Malaga's historic city.MethodologyThe general work plan is based on Brito's diagram (2009) for approaching the concept of the tourist-historic city (Ashworth and Tunbridge, 2000). It consists of analysis of the historic city as a heritage asset, study of the urban cultural tourism phenomenon and work on the definition and management of the tourist-historic city.The analysis of the British and Spanish models has been made comparing the conceptualisation of heritage, legal framework, weight of the public, private and third sectors, distribution of duties among public agencies, funding and listing process.Each study case follows the same process as the theoretical framework. At first, the evolution of heritage preservation and management is analyzed since late 19th century until the first decade of 21st century through a qualitative research based on documents from public archives, urban plans and other administrative documents. The current framework is a comparative analysis on designation of protected historic sectors, national and local listing, heritage at risk, evolution of listing criteria and comparison with other cities from the region.The evolution of urban tourism is based on documents from public archives, urban plans and other administrative documents. There is a specific section for the evolution of references appearing in guidebooks from 1820 to 1990, following the methodology of Marine-Roig (2011) and Gali Espelt (2005). References have been given a specific value and grouped in 12 thematic categories that reflect the evolution on the interest to visit the selected cities. This methodology has been applied to analyze current guidebooks and other sources of information for tourists as well, making it possible to compare present and past main tourist attractions and services.The current impact of tourism-related activities is based on the definition of the tourist system made by De la Calle Vaquero (2006). Data has been collected from fieldwork, leaflets, webpages, routes, current guidebooks, direction signs, panels and plaques. References have been given a specific value and grouped in categories. Information has been processed using a virtual cartography tool, following the methodology of Salerno, Casonato and Villa (2011) and Olukole and Balogun (2011) and finally presented in 13 intensity maps.The study of stakeholders and initiatives on policies affecting management of tourist use in the historic city is based on fieldwork and qualitative analysis of plans and projects from the public administration, public-private agencies, private companies and third sector organisations.ResultsIn an area of the same size, there are 327 listed assets in Plymouth, while in Malaga there are only 45. …
