Attributes conveying cultural significance play a key role in heritage management, as well as in differentiating interventions in built heritage. However, seldom the relation between interventions and attributes, either tangible or intangible, has been researched systematically. How do both tangible and intangible attributes and interventions relate? What attributes make interventions on built heritage differ?

This paper conducts a systematic content analysis of forty-one international doctrinal documents—mainly adopted by the Council of Europe, UNESCO and ICOMOS, between 1877 and 2021. The main aim is to reveal and compare the selected eight intervention concepts, namely—restoration (C1), preservation (C2), conservation (C3), adaptation (C4), rehabilitation (C5), relocation (C6), reconstruction (C7) and renewal (C8)—and their definitions, in relation to attributes, both tangible and intangible. The intensity of the relationship between intervention concepts and attributes is determined based on the frequency of the mentioned attributes per intervention.

There were three key findings. First, although the attention to intangible attributes has increased in the last decades, the relationship between interventions and tangible attributes remains stronger. The highest frequency of referencing the tangible attributes was identified in “relocation” and “preservation,” while the lowest was in “rehabilitation.” Second, certain attributes play contradictory roles, e.g. “material,” “use” and “process,” which creates inconsistent definitions between documents. Third, as attributes often include one another in building layers, they trigger the intervention concepts in hierarchical patterns.

This paper explores and discusses the results of a novel comparative analysis between different intervention concepts and definitions, with a particular focus on the attributes. The results can support further research and practice, clarifying the identified differences and similarities.

Even if there is a wealth of research highlighting the key role of values and cultural significance for heritage management and, defining specific interventions on built heritage, seldom the relation to their leading values and values hierarchy have been researched. How do values and interventions relate? What values trigger most and least interventions on heritage? How do these values relate and characterize interventions? And what are the values hierarchy that make the interventions on built heritage differ?

This paper conducts a systematic content analysis of 69 international doctrinal documents – mainly adopted by Council of Europe, UNESCO, and ICOMOS, during 1877 and 2021. The main aim is to reveal and compare the intervention concepts and their definitions, in relation to values. The intensity of the relationship between intervention concepts and values is determined based on the frequency of mentioned values per intervention.

There were three key findings. First, historic, social, and aesthetical values were the most referenced values in international doctrinal documents. Second, while intervention concepts revealed similar definitions and shared common leading values, their secondary values and values hierarchy, e.g. aesthetical or social values, are the ones influencing the variation on their definitions. Third, certain values show contradictory roles in the same intervention concepts from different documents, e.g. political and age values.

This paper explores a novel comparison between different interventions concepts and definitions, and the role of values. The results can contribute to support further research and practice on clarifying the identified differences.

The heritage and tourist attractiveness of Heritage Cities have aroused interest in establishing mechanisms to enhance their value based on the development of sustainability policies. The socioeconomic and socioenvironmental valuation of these heritage sites has become a necessary tool for decision-making.

Following the recommendations of International Council on Monuments and Sites – ICOMOS, this paper proposes a series of indicators and an exploratory model to define the factors that contribute to their valuation. Following the partial least squares structural equation modelling methodology, information was obtained from 363 intramural residents in the three Heritage Cities that currently have management plans in Spain.

The results show the importance of specifying indicators of sustainable mobility and socioeconomic and socioenvironmental sustainability for an adequate valorisation of heritage sites.

To this end, it is necessary to follow the guidelines of international bodies such as ICOMOS in relation to the management plans.

This paper serves as a pilot study for the education of cultural landscape heritage conservation (CLHC) and review the preparedness of landscape architecture curricula in the Philippines for the CLHC specialization. It proposes the utilization of the “Geodesign” framework in formulating a developmental process and validation of the interrelationship and collaborative activity created by the thematic areas towards landscape heritage education and professionalization. The goal of the study is to create new possibilities for the profession through the study and professionalization of cultural landscapes, thus, raising awareness and significance of cultural heritage and heritage conservation in the lenses of the Philippine landscapes.

The research opted for literature reviews, comprehensive desktop reviews of the landscape architecture syllabi of higher education institutions (HEIs) and SWOT and PESTEL analyses as qualitative assessments, including stakeholder feedback discussions with the current four (4) HEIs, Philippine Association of Landscape Architects (PALA), Technical Committee for Landscape Architecture, Commission on Higher Education (TCLA CHED), Professional Regulation Commission–Board of Landscape Architecture (PRC–BOLA) and the ICOMOS IFLA International Scientific Committee on Cultural Landscapes, National Philippine Committee (Philippine NSCCL). The data were complemented by a quantitative assessment using Leopold and Lohani and Thann assessment matrix on importance (without considering magnitude), and for this study, it is the level of preparedness and integration.

The paper brings forth to the conclusion that the landscape architecture curricula at the bachelor's degree level of the University of the Philippines – Diliman (UP – Diliman) in Quezon City and University of San Carlos (USC) in Cebu are prepared to integrate and/or consider updating their respective curriculum in accordance to the CLHC specialization. The curricula of Bulacan State University (BulSU) in Malolos, Bulacan, and the University of San Agustin (USA) in Iloilo may need to consider introducing courses related to the thematic areas to be able to create an area of basis for integration.

The study is initiated as part of the International Council on Monuments and Sites (ICOMOS) Philippines Internship programme during a master degree study wherein the research is bounded within the limit of its duration. Therefore, the study was able to only identify and chose the possible thematic areas and course concentrations for the specialization of CLHC; select, review and propose courses related to CLHC; screen courses from the landscape architecture curricula of the universities based on its course title, course information (if provided) and cross–checked with Government syllabi; and allocation of units and time per identified course as well as required prerequisite from thematic areas was not covered in this study.

The paper can be used as a tool to engage discussions with the PRC–BOLA in its development of the specialization of CLHC currently being planned. Study topics and themes identified can be the starting point of training programmes that can benefit students of the current four universities in the study and landscape architecture professionals alike. This will eventually translate to benefits to society as heritage conservation methodologies are developed by practitioners who can apply such knowledge to places of cultural and natural significance and develop learnings to concrete heritage laws and policies protecting landscapes.

This paper serves as a pilot study for the education and professionalization of CLHC in the Philippines. Significantly, the development of CLHC specialization in the Philippines shall open various opportunities in developing Philippine cultural landscape heritage conservationists trained at the local context.

Analyses of cultural landscapes need to combine natural and social-cultural components to promote discussions on landscape planning and heritage management. This qualitative research explores the integrated case study of ten municipalities in the “Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato”, Italy, a UNESCO World Heritage cultural landscape. The research aims to raise awareness of its aesthetic-perceptive features, the importance of effective identification of visual impacts and to promote mitigation strategies/actions for updating the current Management Plan.

Two rounds of interviews and focus groups with mayors were performed in 2015 and 2020 to identify trends and drivers of change affecting the territories. Potential mitigation strategies and actions were voted on and selected in response to five critical themes that emerged from the survey, mainly related to real estate and its supplies.

The results suggest tools and policies in the fields of landscape architecture and landscape design that could benefit planning and management at different levels. They support the design of sustainable scenarios, improving mayors' understanding of the significance of cultural landscapes and promoting them as heritage managers. Furthermore, they intend to preserve the authenticity of the landscape by supporting its attributes for long-term conservation.

The research makes an original contribution on the visual implications of anthropogenic landscape transformations in ten municipalities constituting this serial property, six years after its UNESCO nomination (2014).

The general attitude of the ancient theatre conservation strategies and policies is still concerned primarily with their architectural physical appearance without considering their authentic scientific acoustical qualities. The paper attempts to illustrate and discuss how to enhance their acoustic heritage to arouse the audience's interest and needs. Thus, supporting their reconstruction based on recent acoustical research and community needs-related concerns and opportunities for ancient theatre's modern use.

It is based on reviewing the main issues related to reconstruction in the international charters and conventions and how to infuse ancient theatres with their full role. It discusses the dilemma and debates regarding the theatre stage wall, colonnade (portico) restoration and anastylosis. Is it sufficient enough to recover the theatre sound volume? Or to rethink for full physical reconstructions of these missing related acoustical theatre architectural elements to their original level and layout as in ancient times in parallel to their virtual reconstruction?

The cultural significance of the authentic theatre's acoustical qualities needs to reform the conservation strategies and policies for a more flexible and resilient approach. It should be postulated, re-examined and advocated parallel to their 3D virtual reconstruction in the related international charters and conventions.

The paper's implications are not immediate; it is far-reaching. It suggests the importance of acoustics in analysing historic theatre performance venues and reforming conservation strategies and approaches. This issue is especially critical for architects, conservators, the heritage community and the public audience.

Recommendations are made for potential bold reconstruction actions that may be taken to achieve further sustainability, comfort, and permeability in modern theatre-use performances. Their physical reconstruction for improving the performance of contemporary theatre use regarding retaining the acoustic cultural significance should be more flexible and resilient in the charters.

The World Heritage Convention has reached a milestone, and this year, in 2022, it is celebrating its 50th anniversary. The aim of this article is to review whether and how the goals of the strategic action plan (SAP) for the Implementation of the World Heritage Convention (2012–2022) have been reached.

This article starts by considering the outcomes for three of the SAP goals, dealing with protection and management; the credibility of the World Heritage List and sustainable development, using additional information from the final implementation report of the SAP (UNESCO, 2021a), which provides key performance indicators and the implementation status for each goal and associated outcomes. This article then compares and contrasts available data, trends and examples to provide more in-depth analyses of the implementation of the three goals. Data have been gathered from my own research and from the work of other academics and practitioners.

The article finds several key positive changes, including the recent revisions of the Operational Guidelines to include provisions from the 2015 UNESCO Policy on World Heritage and Sustainable Development. However, a number of concerning or worsening trends relating to the protection and management of the World Heritage List, its increasing lack of credibility and sustainable development make it difficult to conclude that the implementation of the goals has been positive. The article concludes with suggestions for addressing these issues.

This paper fills a gap, as not much has yet been published on the state of implementation of the Convention at 50 years old.

This paper aims to address the issue of the conservation and management of rural cultural heritage, with the aim being to gain an understanding of current problems and needs through a participatory approach, in recognition of the uniqueness of the relationship between nature, humankind and the built environment as an area of study. To this end, a comprehensive case study – Kemer Village in Turkey – focusing on the social sustainability and participatory approaches for the sustainable development of rural settlements is given. Accordingly, possible conservation, management and sustainability strategies are put forward considering the priorities and perspectives of different stakeholders.

This paper approaches the subject of rural heritage conservation and management from a social sustainability standpoint, involving an on-site investigation to understand the physical and social context of Kemer Village in Turkey, which has links to different periods in history, and contains significant examples of vernacular architecture and that has maintained its cultural characteristics. Tools and criteria for participatory planning approach were applied ensuring the involvement of the local community and stakeholders.

The findings of the present study reveal rural settlements to be important factors in the cultural heritage conservation and indicate the importance of prescient management and the adoption of a sustainable development model. Achieving the desired level of sustainability in historical villages through conservation of the built environment with the involvement of the local community is possible, as can be seen in the case of Kemer Village in Turkey, where the villagers and the local authorities worked in cooperation to ensure the preservation of the village's integrity.

This study will describe possible long-term strategies and actions aimed at involving the local community in the sustainable conservation of the rural cultural heritage while also embracing change. It is important that the concept of sustainability is realized with participatory planning methods. In addition to that, rural heritage and social sustainability together incorporate a widespread but rarely considered set of issues addressing local needs in conservation.

This paper introduces a methodology to identify, analyse and represent heritage site attributes, emphasizing their impact on value, authenticity, integrity and management, with a case study on Ghadames, Libya. Inscribed in 1986 and moved to the In-Danger List in 2016 due to conflict, this work seeks to update the site's attributes and values for improved management.

This methodology, focusing on Ghadames, leverages recent heritage management advancements to monitor conflict-induced changes, aiming to enhance decision-making through a detailed analysis of the site's natural and cultural attributes.

Our findings highlight the need for systematic and holistic assessments of heritage site attributes and values, crucial for managing sites of both local and global significance. This approach is a key to understanding their identity, guiding interpretation, management and preserving cultural significance.

Developed for Ghadames, the methodology requires adaptation for other sites, underscoring the importance of identifying core tangible and intangible attributes that define a site's uniqueness.

Our developed methodology offers a replicable framework that can be modified by local heritage professionals to map attributes and assess the direct and indirect impact of conflict on heritage sites.

The detailed assessment provides a foundation for crafting informed policies and effective management strategies. It specifically targets minimizing the adverse effects of conflict on heritage sites' attributes. This effort is instrumental in preparing the necessary documentation to support the delisting of these sites from the UNESCO World Heritage Site In-Danger List, promoting their preservation and recovery.

A comprehensive understanding of the determining factors and implications of the frameworks for appreciating the relationships between climate risks and cultural heritage remains deficient. To address the gap, the review analysed literature on the management of climate risk in cultural heritage. The review examines the strengths and weaknesses of climate risk management (CRM) frameworks and attendant implications for the conservation of cultural heritage.

The study adopted a two-phased systematic review procedure. In the first phase, the authors reviewed related publications published between 2017 and 2021 in Scopus and Google Scholar. Key reports published by organisations such as the United Nations Educational, Scientific and Cultural Organisation (UNESCO) and International Council on Monuments and Sites (ICOMOS) were identified and included in Phase Two to further understand approaches to CRM in cultural heritage.

Results established the changes in trend and interactions between factors influencing the adoption of CRM frameworks, including methods and tools for CRM. There is also increasing interest in adopting quantitative and qualitative methods using highly technical equipment and software to assess climate risks to cultural heritage assets. However, climate risk information is largely collected at the national and regional levels rather than at the cultural heritage asset.

The review establishes increasing implementation of CRM frameworks across national boundaries at place level using high-level technical skills and knowledge, which are rare amongst local organisations and professionals involved in cultural heritage management.

The review established the need for multi-sectoral, bottom-up and place-based approaches to improve the identification of climate risks and decision-making processes for climate change adaptation.
