Special Issue Information

Dear Colleagues,

The evolution of the concept of heritage, including its complexity and environments, requires the updating of the associated cultural values that, in the case of many World Heritage declarations, should complete the stated outstanding universal values. This task, as the Faro Convention pointed out, must be carried out with communities, implementing participatory strategies. This makes it difficult to embrace sustainable conservation practices and, particularly, Heritage Impact Assessments (HIAs) in change management situations.

HIAs, which comply with the Operational Guidelines for the Implementation of the World Heritage Convention, should serve to identify development alternatives, as well as potentially positive and negative impacts, and to recommend mitigation measures against degradation. They are therefore appropriate in terms of improving change management processes by facilitating dialogue among all stakeholders.

This Special Issue aims to identify, from theoretical implementation frameworks, sustainable conservation policies based on the actualisation of sustainable values for heritage assets from a social perspective. Although this proposal is framed within the WHATS-UP research project (‘World Heritage: an Approach To Social sustainability while UPgrading cultural values’), we welcome contributions that address the abovementioned issues in cultural heritage properties of any other kind, such as industrial heritage, modern heritage, monumental heritage, archaeological heritage, or rural heritage, among other possibilities.

The discussions in this Special Issue will focus on (but are not limited to) the following thematic areas:

  • The evolution of the heritage concept and the implementation of the international charters and texts of reference in the field
  • From theory to practice: intervention criteria and project decisions to better understand and conserve heritage
  • Documentary procedures to better manage heritage: archives, databases, information systems, BIM, SIG, etc.
  • Sustainable heritage management based on values
  • The identification of cultural values and attributes
  • Heritage Impact Assessments in World Heritage
  • Good practices in heritage conservation and management
  • Monitoring and quality control of processes for heritage conservation
  • Collaborative methodologies in identifying, managing, protecting, and conserving heritage assets
  • The contribution of contemporary architecture to heritage co-creation

This research addresses the latent disconnect between citizens and World Heritage sites, analysing how intensive tourism and declarations focused on monuments (1980s–1990s) have created a distance that makes managing these heritage sites very difficult. The main objective is to propose and validate participatory methodologies that restore social bonds and strengthen urban governance. The identified knowledge gap lies in the lack of operational tools that allow the theory of participation to be put into actual practice, overcoming the current methodological void in assessing social and economic impacts. Under the methodology of the WHATS-UP project, an action-research approach is employed that combines ethnographic work, mapping of key actors, and participatory workshops with shared walking tours in the Alhambra and the Alcázar. This data is integrated into Participatory Geographic Information Systems (PPGIS) to map social perceptions of values and risks. The results show that, although tourism has led to alienation and gentrification, the participatory process succeeds in rescuing “invisible values”, such as memories and traditional trades, that are absent from official narratives. In conclusion, the study proposes a consensus-based co-management model between institutions and the community, transforming heritage into a resource for urban cohesion and resilience. This integration of methodologies, which combines collective mapping with safeguarding plans, enables progress toward protection strategies that are more effective and better reflect contemporary social realities.

Many World Heritage Sites hold universal and exceptional values of a hybrid nature, combining cultural and environmental richness. Yet these complex dimensions are rarely recognised within their designation criteria, making it urgent to update their cultural valuation through the lens of social and environmental sustainability. In this context, water—as both a natural and a cultural asset—emerges as a fundamental element for understanding their natural–cultural capital. This study examines two World Heritage Sites in southern Spain—the Royal Alcázar of Seville and the Alhambra of Granada—which are particularly representative at the European scale due to their severe climatic conditions. The methodology is based on the analysis and mapping of their landscape conditions using historical cartography and Geographic Information Systems, together with a review of water-related attributes and values across their protection and management frameworks. As a result, their water systems are critically assessed within existing protection and management documents, a narrative approach to water as natural-cultural capital is proposed, and this approach is linked to the sites’ principal climate-related vulnerabilities and benefits. Overall, the study contributes to the international debate on biocultural heritage, supporting the need to update the water system approach applied to World Heritage Sites under conditions of climate stress.

This study presents the first systematic regional assessment of how the Historic Urban Landscape (HUL) approach has been understood and applied in Latin American and Caribbean (LAC) cities between 2011 and 2022. The HUL approach is framed as a socio-spatial perspective shaped by historical layering, cultural practices, ecological structures, and contemporary development pressures. A systematic review of academic publications and institutional gray literature (Scopus, Google Scholar, and municipal repositories) was conducted to evaluate both conceptual understanding and methodological implementation aligned with the six steps of the 2011 HUL Recommendation. Findings reveal a clear implementation gap: although awareness of the HUL approach has increased across the region, its practical application remains partial. Steps 1 and 2 focused on value identification and participatory engagement show the highest adoption, while steps 4 and 6 which require interinstitutional coordination and integration into statutory planning instruments exhibit limited progress. Academic and research institutions play a more prominent role than local governments in leading or supporting HUL-related actions, indicating persistent institutional and governance constraints. Results highlight the need to strengthen municipal capacities, integrate HUL-based diagnostics into urban planning systems, and consolidate participatory, interdisciplinary, and multilevel governance mechanisms to close the gap between conceptual uptake and operational implementation.

Egypt’s heritage villages are living cultural landscapes that remain largely undocumented and insufficiently protected under current national frameworks. This study develops the Enhanced Heritage Value Index (EHVI) a UNESCO-aligned framework designed to quantitatively and qualitatively assess the conservation readiness of heritage villages in Egypt. EHVI was developed through a mixed-method approach integrating conceptual analysis of UNESCO and ICOMOS standards, expert-based weighting of 31 validated heritage indicators, and community perception surveys conducted across seven villages in Luxor Governorate. The EHVI provides a scalable and replicable assessment tool that classifies villages into high, moderate, and low readiness levels, enabling decision-makers to prioritize conservation interventions. As Egypt’s first composite index tailored to rural heritage contexts, this framework bridges national policy needs with international heritage criteria and offers a strategic foundation for future UNESCO nominations and sustainable heritage management. This research fills a critical theoretical and practical gap by operationalizing the Historic Urban Landscape (HUL) paradigm in a rural Egyptian context, thereby advancing heritage assessment methodologies beyond urban-centered models.

The British colonial contact with Nigeria was dotted with diverse paradoxes. In the realm of architecture, it was a period punctuated with the importation of prefabricated buildings into many slave and palm oil trading towns, such as Old Calabar in southern Nigeria. Unfortunately, today, many of these prefabricated colonial architectural heritages have gone into extinction, except for a few which are also on the verge of collapse. One of the remaining few on the verge of collapse is the Egbo Egbo Bassey House built between 1883 and 1886 and declared a National Monument of Nigeria in 1959. Currently, there is no literature on the historical and architectural data of this building, besides those scattered over several files in archival records. Therefore, this paper aims at the holistic documentation of the National Monument. Two categories of data were considered in the documentation processes—namely the building historical data and geometrical data. Historical data were collected through archival research and interviews, while the geometrical data were collected through close-range photogrammetry and manual measurements. The result of this paper contributes to the current geographical dearth of literature on British prefabricated architectural heritage, which punctuated a very important period in the architectural history of the world.

This study examines how the notion of value is defined, recognised, and operationalised within the four main approaches to cultural heritage preservation: the material-based, value-based, living heritage, and historic urban landscape approaches. Positioned within the broader discourse on the evolving understanding of cultural heritage—from fixed, expert-driven interpretations toward more contextual, socially constructed, and participatory perspectives—this research aims to address which value types are recognised, and how and to what extent they are operationalised by applying four main approaches to cultural heritage preservation. The methodology comprises four phases: (1) the identification, search, and selection of academic articles in the Scopus database, (2) sample overlapping and elimination of duplicates to establish a final dataset, (3) bibliometric analysis to determine publishing trends and disciplinary reach, and (4) content analysis to identify, classify, and compare value types across the selected approaches. The results reveal significant variation in how values are represented, as well as notable inconsistency in their direct inclusion in research processes. While cultural, historical, aesthetic, social, and economic values dominate across approaches, only a fraction of studies operationalise values through defined criteria or indicators. The findings highlight the absence of consensus in value interpretation and emphasise the need for more systematic, integrative, and operationalisable frameworks for treating values in the process of cultural heritage preservation.
