Resolving the conflicts of sustainable world heritage landscapes in cities : fully open or limited access for visitors?

World Heritage Landscapes (WHLs) are receiving increased attention from researchers, urban planners, managers, and policy makers and many heritage values and resources are becoming irreversibly lost. This phenomenon is especially prominent for WHLs located in cities, where greater development opportunities are involved. Decision making for sustainable urban landscape planning, conservation and management of WHLs often takes place from an economic perspective, especially in developing countries. This, together with the uncertain source of funding to cover WHL operating and maintenance costs, has resulted in many urban managers seeking private sector funding either in the form of visitor access fees or leasing part of the site for high-rental facilities such as five star hotels, clubs and expensive restaurants. For the former, this can result in low-income urban citizens being unable to afford the access fees and hence contradicting the principle of equal access for all; while, for the latter, the principle of open access for all is equally violated. To resolve this conflict, a game model is developed to determine how urban managers should allocate WHL spaces to maximize the combination of economic, social and ecological benefits and cultural values. A case study is provided of the Hangzhou's West Lake Scenic Area, a WHL located at the centre of Hangzhou city, in which several high-rental facilities have recently been closed down by the local authorities due to charges of elitism and misuse of public funds by government officials. The result shows that the best solution is to lease a small space with high rents and leave the remainder of the site to the public. This solution is likely to be applicable only in cities with a strong economy.

Using an ‘interpretative model’ for contextual design of heritage landscape databases: The case of St Helena Island National Park in Queensland, Australia

Due to the increasing speed of landscape changes and the massive development of computer technologies, the methods of representing heritage landscapes using digital tools have become a worldwide concern in conservation research. The aim of this paper is to demonstrate how an ‘interpretative model’ can be used for contextual design of heritage landscape information systems. This approach is explored through building a geographic information system database for St Helena Island national park in Moreton Bay, South East Queensland, Australia. Stakeholders' interpretations of this landscape were collected through interviews, and then used as a framework for designing the database. The designed database is a digital inventory providing contextual descriptions of the historic infrastructure remnants on St Helena Island. It also reveals the priorities of different sites in terms of historic research, landscape restoration, and tourism development. Additionally, this database produces thematic maps of the intangible heritage values, which could be used for landscape interpretation. This approach is different from the existing methods because building a heritage information system is deemed as an interpretative activity, rather than a value-free replication of the physical environment. This approach also shows how a cultural landscape methodology can be used to create a flexible information system for heritage conservation. The conclusion is that an ‘interpretative model’ of database design facilitates a more explicit focus on information support, and is a potentially effective approach to user-centred design of geographic information systems.

Tourism potential analysis of the castles of Vinalopó, Spain: an opportunity for social and tourist development of cultural heritage

Within the overall framework of the renewal process of coastal tourist destinations, cultural heritage has frequently been used as a key argument for the introduction and development of strategies for the diversification and differentiation of the traditional tourist product based on sun and sand. This is the situation of the province of Alicante, identified with the Costa Blanca geotourism brand, where there are important economic issues that could contribute to the renewal of this coastal tourist destination. One of the most significant heritage values of this space consists of a series of medieval fortresses located along the axis of the Vinalopó River, which has acted since prehistoric times as a natural route from within the provincial mainland to the coast. It is precisely the argument of this historical, territorial and landscape content that has been used repeatedly in recent years to develop initiatives aimed at the creation of a tourist product, currently inexistent, based on the route of the castles of Vinalopó. This communication aims to analyse the degree of tourism potential of the fortresses located in the towns of Biar, Banyeres de Mariola, Sax, Villena, Novelda, Elda, Petrer and Elche, which constitute the core of municipalities where these medieval fortresses are located, finally pointing out some proposals for the creation of a heritage tourism product.

Threshold concepts in property education : a case study

First year Property Economics students enrolled in the Bachelor of Urban Development at QUT are required to undertake a number of compulsory subjects, alongside students undertaking studies in other disciplines. One such common unit is ‘Stewardship of Land’, an interdisciplinary unit that introduces students to the characteristics of land and land tenure with a focus on land use and property rights. It covers a range of issues including: native title, land contamination, heritage values, alternative uses, the property development process, impact of environmental and social factors, and the management of land, both urban and regional. Teaching such a diverse content to a diverse audience has in previous years proved difficult, from the perspectives of relevance, engagement and content overload. In 2011 a project was undertake to redevelop this unit to reflect ‘threshold concepts’, concepts that are “transformative, probably irreversible, integrative, often troublesome and probably bounded” (Meyer & Land, 2003) . This project involved the development of a new set of underlying concepts students should draw from the unit, application of these to the unit curriculum, and a survey of the student response to these changes. This paper reports on the threshold concepts developed for this unit, the changes this made to the unit curriculum, and a preliminary report on survey responses. Recommendations for other educators seeking to incorporate threshold concepts into their curricula are provided.

Targeted control of feral pigs in far north Queensland : defining management units using molecular techniques

The feral pig, Sus scrofa, is a widespread and abundant invasive species in Australia. Feral pigs pose a significant threat to the environment, agricultural industry, and human health, and in far north Queensland they endanger World Heritage values of the Wet Tropics. Historical records document the first introduction of domestic pigs into Australia via European settlers in 1788 and subsequent introductions from Asia from 1827 onwards. Since this time, domestic pigs have been accidentally and deliberately released into the wild and significant feral pig populations have become established, resulting in the declaration of this species as a class 2 pest in Queensland. The overall objective of this study was to assess the population genetic structure of feral pigs in far north Queensland, in particular to enable delineation of demographically independent management units. The identification of ecologically meaningful management units using molecular techniques can assist in targeting feral pig control to bring about effective long-term management. Molecular genetic analysis was undertaken on 434 feral pigs from 35 localities between Tully and Innisfail. Seven polymorphic and unlinked microsatellite loci were screened and fixation indices (FST and analogues) and Bayesian clustering methods were used to identify population structure and management units in the study area. Sequencing of the hyper-variable mitochondrial control region (D-loop) of 35 feral pigs was also examined to identify pig ancestry. Three management units were identified in the study at a scale of 25 to 35 km. Even with the strong pattern of genetic structure identified in the study area, some evidence of long distance dispersal and/or translocation was found as a small number of individuals exhibited ancestry from a management unit outside of which they were sampled. Overall, gene flow in the study area was found to be influenced by environmental features such as topography and land use, but no distinct or obvious natural or anthropogenic geographic barriers were identified. Furthermore, strong evidence was found for non-random mating between pigs of European and Asian breeds indicating that feral pig ancestry influences their population genetic structure. Phylogenetic analysis revealed two distinct mitochondrial DNA clades, representing Asian domestic pig breeds and European breeds. A significant finding was that pigs of Asian origin living in Innisfail and south Tully were not mating randomly with European breed pigs populating the nearby Mission Beach area. Feral pig control should be implemented in each of the management units identified in this study. The control should be coordinated across properties within each management unit to prevent re-colonisation from adjacent localities. The adjacent rainforest and National Park Estates, as well as the rainforest-crop boundary should be included in a simultaneous control operation for greater success.

Assessing the suitability of existing spatial data for disaster planning and mitigation in Queensland

The Council of Australian Governments (COAG) in 2003 gave in-principle approval to a best-practice report recommending a holistic approach to managing natural disasters in Australia incorporating a move from a traditional response-centric approach to a greater focus on mitigation, recovery and resilience with community well-being at the core. Since that time, there have been a range of complementary developments that have supported the COAG recommended approach. Developments have been administrative, legislative and technological, both, in reaction to the COAG initiative and resulting from regular natural disasters. This paper reviews the characteristics of the spatial data that is becoming increasingly available at Federal, state and regional jurisdictions with respect to their being fit for the purpose for disaster planning and mitigation and strengthening community resilience. In particular, Queensland foundation spatial data, which is increasingly accessible by the public under the provisions of the Right to Information Act 2009, Information Privacy Act 2009, and recent open data reform initiatives are evaluated. The Fitzroy River catchment and floodplain is used as a case study for the review undertaken. The catchment covers an area of 142,545 km2, the largest river catchment flowing to the eastern coast of Australia. The Fitzroy River basin experienced extensive flooding during the 2010–2011 Queensland floods. The basin is an area of important economic, environmental and heritage values and contains significant infrastructure critical for the mining and agricultural sectors, the two most important economic sectors for Queensland State. Consequently, the spatial datasets for this area play a critical role in disaster management and for protecting critical infrastructure essential for economic and community well-being. The foundation spatial datasets are assessed for disaster planning and mitigation purposes using data quality indicators such as resolution, accuracy, integrity, validity and audit trail.

Feral pig populations are structured at fine spatial scales in tropical Queensland, Australia

Feral pigs occur throughout tropical far north Queensland, Australia and are a significant threat to biodiversity and World Heritage values, agriculture and are a vector of infectious diseases. One of the constraints on long-lasting, local eradication of feral pigs is the process of reinvasion into recently controlled areas. This study examined the population genetic structure of feral pigs in far north Queensland to identify the extent of movement and the scale at which demographically independent management units exist. Genetic analysis of 328 feral pigs from the Innisfail to Tully region of tropical Queensland was undertaken. Seven microsatellite loci were screened and Bayesian clustering methods used to infer population clusters. Sequence variation at the mitochondrial DNA control region was examined to identify pig breed. Significant population structure was identified in the study area at a scale of 25 to 35 km, corresponding to three demographically independent management units (MUs). Distinct natural or anthropogenic barriers were not found, but environmental features such as topography and land use appear to influence patterns of gene flow. Despite the strong, overall pattern of structure, some feral pigs clearly exhibited ancestry from a MU outside of that from which they were sampled indicating isolated long distance dispersal or translocation events. Furthermore, our results suggest that gene flow is restricted among pigs of domestic Asian and European origin and non-random mating influences management unit boundaries. We conclude that the three MUs identified in this study should be considered as operational units for feral pig control in far north Queensland. Within a MU, coordinated and simultaneous control is required across farms, rainforest areas and National Park Estates to prevent recolonisation from adjacent localities.

Claves para el reconocimiento de la dehesa como "paisaje cultural" de Unesco

La dehesa española y su homónimo portugués (el montado) son sistemas agrosilvopastoriles mediterráneos que proyectan un paisaje excepcional y de elevados valores patrimoniales. Sobre ellos se ciernen nuevas o renovadas amenazas que comprometen su futuro, en un momento (el actual) de creciente revalorización socio-institucional de sus paisajes. Su declaración como paisaje cultural de Unesco puede constituir un potente instrumento para atajar dichas amenazas, pero requiere de la clarificación de ciertos interrogantes relacionados con las escalas. Este artículo se adentra en el valor universal excepcional de la dehesa y propone algunas claves para sustentar su posible incorporación a la Lista de Patrimonio Mundial de Unesco. El análisis se acomete a nivel de tipos de paisaje, pero se avanzan algunos criterios para la selección de ámbitos concretos y representativos susceptibles de integrar una candidatura como “bien en serie”.

Vers une nouvelle définition du patrimoine : l'intégration du développement durable dans l'évaluation patrimoniale

Devant le contexte actuel des crises environnementale et sociale, on ne peut que s’interroger sur la capacité du domaine de la conservation du patrimoine à intégrer les principes et les concepts liés au développement durable. Alors que plusieurs liens entre la conservation du patrimoine culturel et le développement durable existent, il devient nécessaire de solidifier cette union. Réalisée en amont du projet de conservation, l’évaluation patrimoniale basée sur l’approche par les valeurs permet d’établir la signification d’un lieu selon les valeurs qui lui sont associées. Il y a cependant lieu de se questionner : au-delà des valeurs historiques, esthétiques ou architecturales traditionnellement attribuées au patrimoine bâti, quel intérêt accorde-t-on aux dimensions environnementales, économiques et sociales? Le postulat de ce mémoire est qu’il est essentiel d’élargir l’évaluation patrimoniale afin d’y intégrer de nouvelles valeurs liées au développement durable. Nous nous proposons d’étudier la faisabilité de ceci en élaborant un modèle d’évaluation patrimoniale basé sur une approche par les valeurs qui prend en compte l’ensemble des valeurs inhérentes au patrimoine bâti, c’est-à-dire les aspects culturels, sociaux, économiques et environnementaux. Cette proposition se traduit en une grille d’évaluation qui comporte ces dimensions. Afin de confronter notre hypothèse au réel, nous procéderons à une étude de cas : le Silo no.5 situé dans le Vieux-Port de Montréal. Aux termes de cette recherche, nous estimons être en mesure d’identifier les limites de notre expérimentation et de déterminer ce qui pourrait être fait pour contribuer aux efforts en conservation. Il nous apparaît que les recherches effectuées dans le cadre de ce mémoire sont susceptibles d’intéresser toute personne oeuvrant dans le domaine de la conservation du patrimoine.

An approach to compatible new buildings in historic urban environments : case study in the Arabian Gulf region

Cette thèse contribue à l'état actuel des connaissances sur la compatibilité des nouveaux bâtiments avec les environnements urbains historiques. Elle suit un mode de présentation classique: Introduction, Revue de Littérature, Méthodologie, Résultats, Discussion et Conclusion. Le problème étudié est le manque d'orientation pour intégrer les processus de développement et de sauvegarde dans les contextes établis. La littérature récente révèle que les règles de préservation, aussi appelées normes et lignes directrices, ne peuvent pas garantir une relation compatible entre une intervention et son milieu. La pensée contemporaine dans le domaine de la conservation et de la gestion du patrimoine invite donc l’exploration d'autres moyens pour lier la nouvelle architecture à l'ancienne. Ainsi, le présent projet de recherche explore une approche alternative aux règles de préservation en vue d’atteindre le but de nouveaux bâtiments compatibles et d’améliorer la prise de décision fondée sur les valeurs. Pour produire des résultats spécifiques et convaincants, un cas a été sélectionné. Celui-ci est une ville dans la région du Golfe Arabe : la Ville de Koweït. Le résultat principal est le développement d’une approche, mise en œuvre en posant des questions approfondies sur le lieu, la conception et la construction des nouveaux bâtiments. Les questions suggérées dans la thèse mettent l’accent sur les valeurs patrimoniales et les choix de conception afin de permettre un changement réfléchi au sein des environnements urbains historiques. Elles aident aussi à évaluer les nouvelles propositions de projets au cas par cas. Pour démontrer comment cette approche pourrait être présentée et utilisée par les requérants et les évaluateurs, un modèle théorique est proposé. Ce modèle a ensuite été discuté avec des professionnels locaux et internationaux qui ont identifié ses forces et ses limites. En conclusion, l’ensemble des résultats montre que la mise à disposition de règles et / ou de questions approfondies n’est pas une solution satisfaisante puisqu’il y a d'autres enjeux importants qui devraient être abordés: comment appliquer l'orientation efficacement une fois qu’elle a été créée, comment développer la compétence liée à la prise de décision fondée sur les valeurs et comment insérer la conservation du patrimoine dans la mentalité du gouvernement local et des communautés. Lorsque ces enjeux seront traités, le patrimoine pourra devenir partie intégrante du processus de planification, ce qui est le but ultime. Enfin, cinq axes de recherche sont recommandés pour poursuivre l’exploration des idées introduites dans cette étude.

La gestion du cadre bâti dans l'Arrondissement historique et naturel du Mont-Royal

Lorsqu’un site ou un bien est protégé par un statut patrimonial, tant national que local, les règlements d’urbanisme sont un des principaux outils d’encadrement des modifications de l’environnement bâti. Comment ces règlements participent-ils à la conservation des valeurs patrimoniales ? Pour explorer cette question, nous avons choisi le cas de l’arrondissement historique et naturel du Mont-Royal (AHNMR, renommé en 2012 site patrimonial du Mont-Royal), un site majeur pour l’identité de Montréal. Nous avons recensé les valeurs patrimoniales attribuées au site et analysé le processus de gestion des projets dans les quatre arrondissements qui se répartissent la partie montréalaise du territoire de l’AHNMR; nous avons également analysé quelques demandes de permis. Le processus est complexe, d’autant plus que l’évaluation est en bonne partie discrétionnaire, incluant des analyses de fonctionnaires et de comités consultatifs de même que des exercices de consultation publique. La recherche a permis de mettre en lumière que les règlements d’urbanisme ont tendance à se concentrer sur les valeurs dont la matérialité est connue (valeurs architecturales et paysagères notamment) et à délaisser les valeurs immatérielles (valeurs d’usage, valeurs identitaires et emblématiques). La juxtaposition des valeurs peut atténuer ce déséquilibre en protégeant une valeur immatérielle par l’entremise d’une valeur matérielle. La documentation des valeurs patrimoniales et de leur incarnation dans l’aménagement d’un site revêt une importance majeure pour l’application des critères d’évaluation. De plus, l’évaluation discrétionnaire apporte de multiple points de vue sur un projet, des opinions d’acteurs, experts en patrimoine ou non, généralement absents de l’évaluation des projets, ce qui contribue à l’évolution de ces derniers. Les consultations publiques donnent lieu à la réévaluation des valeurs patrimoniales ainsi qu’à l’approfondissement des connaissances.

Percepção ambiental do patrimônio cultural: estudo de caso na Cidade Alta e Ribeira em Natal-RN

Contemporary studies have shown that the evolution of the heritage concepts is accompanied by an affirmation of the importance of social participation in recognizing heritage values and in managing cultural assets. We used the Brazilian context to emphasize the challenges for democratizing this process. This problematic is discussed based on the cases of Cidade Altaand Ribeira, neighborhoods that date from the formation of Natal-RNand have cultural assets recognized by levels of government. The study builds elements to answer the research question: what meanings and representations does the culturalheritage in the case study have for its users? The research method analyzes the representations and the meanings of the neighborhoods, firstly is based on historiographical studies, memories records of the city and on the process of heritage management. Secondly, it isbased on the field research, it is structured in environmental perception studies (areas of Environmental Psychology, Architecture and Urbanism) and has been applied with users with different bonds with the studied environment (residents, workers and visitors). The data were obtained with the multi-method which included direct observation, questionnaire survey and mentalmaps (that replicate Kevin Lynch). The analysis of result verified the research hypothesis, emphasizing aspects of the relationship between users and cultural heritage relevant to strengthening collective memory, local identity, contributing to heritage management. Among the results, the socio-environmental image obtained which emphasized a "cultural axis" linkingboth studied neighborhoods and confirms the influences of elements rein the memories records of the city and in the area s management. Identified aspects to strengthen the relationship between the users and cultural assets, such as the presence of placeswith affective ties to certain groups, as well as the need to fight off negative images (of degradation and insecurity) associated to the site and also expand the participation of the population, including residents, in policies and cultural activities. After all, recognition of value and the involvement of societycultural assets have the potential of contribute to integrate city development with heritage conservation

Estrategias, sistemas y tecnologías para el uso de luz natural y su aplicación en la rehabilitación de edificios históricos

La presente tesis investiga sobre la manera en que la arquitectura se ha construido para utilizar la luz natural, con el fin de aplicar estos conocimientos a la rehabilitación de edificios históricos. Para ello es necesario conocer aspectos técnicos en el uso de la luz, partiendo por comprender cuáles son los fenómenos físicos que debiéramos conocer los arquitectos para poder utilizarla adecuadamente. Es necesario también saber cómo es el comportamiento de los materiales frente a la luz y cómo utilizar¬los en el contexto rehabilitación. Dentro de los aspectos técnicos, se establece cuáles son las estrate¬gias, los sistemas y las tecnologías necesarias para la utilización de la luz en arquitectura, y se organiza esta información con el fin de hacerla clara, accesible y útil. Sin embargo, la luz no puede ser empleada en forma adecuada si no se conocen los requerimientos y las necesidades que el ser humano tiene respecto de ella, para habitar en forma confortable y salu¬dable. Es por eso que se establecen a su vez los requerimientos humanos respecto de la luz desde el punto de vista de sus características biológicas, su percepción y sus necesidades ergonómicas. Como la tesis se enmarca dentro de la problemática de la rehabilitación de edificios históricos, es necesario conocer cuál es la relación entre los procesos histórico-culturales y la técnica para utilizar la luz en la historia de la arquitectura. Se busca establecer la correlación entre historia y técnica, con el fin de responder en forma adecuada a los valores patrimoniales de un edificio histórico al alterar un aspecto tan importante como su iluminación natural. Con este conjunto de conocimientos técnicos, humanos e históricos establecidos en la primera parte de la tesis, se propone un protocolo de diseño para un proyecto de rehabilitación en cinco casos de estudio. Esta herramienta analiza el comportamiento actual de la luz para una determinada función, detecta los problemas lumínicos, establece criterios para la elección de soluciones y analiza el compor¬tamiento de estas soluciones. Finalmente compara los resultados lumínicos de las condiciones actua¬les y la solución propuesta. Por último, la investigación genera criterios que pueden ser aplicables a la normativa chilena de plani¬ficación territorial respecto del uso de la luz en contextos urbanos patrimoniales. ABSTRACT This thesis addresses how the architecture has been built to use natural light, in order to apply this knowledge to the historic buildings rehabilitation. This requires knowing technical aspects in the use of light, starting to understand what physical phenomena we, the architects, should know to use it properly. It is also necessary to know how materials behave in regards to light and how to use it in the rehabilitation context. Among the technical aspects, we should define strategies, systems and techno¬logies necessary for the use of light in architecture, and organize this information in order to make it clear, available and useful. However, light cannot be used properly if are not known requirements and needs that human beings have towards it, to live in comfortable and healthy way. That is why light human requirements are determined to know how light influences their cycles, perception and comfort. As the thesis is in frame of rehabilitation of historic building problem, it is necessary to know how is the relationship between historic-cultural processes and technology of light use, in the architecture history. It seeks to establish the correlation between History and technology, in order to give an ade¬quately answer to the heritage values of a historic building by altering an important aspect like its natural lighting. With this set of technical, human and historical knowledge, established in the first part of the thesis, a protocol is proposed for a rehabilitation project design in five study cases. This tool analyzes current behavior of light for a specifically function, detects lighting problems, establishes criteria for the selec¬tion of solutions and analyzes solution behaviors. Additionally, it compares results of current lighting conditions and the proposed solution. Finally this research generates criteria that may be applicable to Chilean territorial planning legislation, regarding use of light in patrimonial urban contexts.

La expansión del área urbana de Segovia. Transformación paisajística del entorno rural periurbano

En la última década, el área urbana de Segovia ha experimentado un profundo cambio radicado en la urbanización de municipios del entorno rural periurbano. Los crecimientos más significativos se han dado en los núcleos situados en torno al eje de la carretera CL-601 que une Segovia con el Real Sitio de San Ildefonso. La expansión del área urbanizada en este espacio genera cambios en la dinámica territorial que pueden llegar a producir desajustes funcionales que afecten negativamente a los valores patrimoniales y paisajísticos que definen a este territorio.

A releitura de um documento: o processo de tombamento do centro histórico de Natal (RN)

During over seven decades of institutionalizing the national heritage protection legal instrument it can be noticed the many ways of the instrument application, according to the approaches that were assigned to the spaces with heritage values and the dynamic of the elaborated thoughts within this theme. For the application of the instrument effectively, there is a long process that is carried out. This process begins with the study elaboration that aims to subsidize and justify the motivation of property protection, as well as the proposal of buffer zones and national protection areas delimitations, completing the process with the denial of the request or with the publication of the definitive national protection area at the Official Gazette. Starting with the relation between the existing heritage values identification into the historical centres and the definition of its protection areas that the area management will be done, based as well into the management intervention norms established for the protection area perimeter. From this context, the present essay has as porpoise to discuss the approach used for the identification and selection of a historical centre liable for national protection and the repercussion of this identification into the national protection area the was established, using a case study of the national protection of the historical centre of the city of Natal. Starting from the assumption that there are inconsistences and distortions about the text speech of the written document and the spatial delimitation of this document, motivated by an area that privileges the edifications rather than the urban space. Beginning with the urban history methodology, we are based on the precepts of Rossi (2011), Lamas (2010) and Cullen (2009) for that space reading, along with what Sant’Anna (2004) defines as “city-document” to make a new reading of this “heritage value space” verifying if the proposed protection area reflects what is defined as motivation for the national protection area process during the recognizing process. Therefore, it is concluded that it is essential that the buffer zones and the national protection areas are aligned with the text presented at the national protection area instruction, so the norms and criteria definition management process are established. We highlight that a site management and the identified values protection become very difficult without a specific law that beacon the decisions that should be taken.
