CiaBOT: the circular design of an experimental microarchitecture between material and immaterial values

The transition to a circular economy entails new challenges for architects and designers. Among these, one challenge is to look at waste not only as new resources, from an environmental perspective, but also as bearers of information capable of communicating their history and origin. Moreover, waste can be considered as a means of activating unexpected knowledge and social connections. The article illustrates a circular design experimentation, conducted with architecture and design students and a wine farm, which led to the creation of the CiaBOT project, a belvedere aimed at enhancing the landscape and providing a temporary stopping point in the Monferrato hills (UNESCO World Heritage Site, Italy). CiaBOT is not only a belvedere but is a microarchitecture capable of conveying both material and immaterial cultural values. Its form and materials are intimately connected with the territory with and for which it was designed. These make CiaBOT a “space” of hybridization and dialogue between agricultural tradition and innovation. But it is also a “space” of fieldwork education and knowledge co-generation in which academic and non-academic stakeholders have measured themselves. Through the description of the different stages of the design process, the article is part of the debate on new sustainable ways of designing and building, reflecting on new models of circular economy based as much on design strategies and processes as on the enhancement of human labor and the use of technologies appropriate to the context and actors.

EXPLORING HOW SUSTAINABLE DESTINATION PREFERENCE MEDIATES THE EFFECTS OF TOURISTS' MOTIVATION ON SATISFACTION

This study investigates the effect of Sustainable Destination Preference (SDP) on the relationship between escapism motivation, affordability perception, and tourist satisfaction at UNESCO World Heritage Sites in Indonesia. A survey was conducted on 228 international tourists, and analyzed through Confirmatory Factor Analysis and Structural Equation Modeling. SDP significantly mediates the relationship between escapism motivation and tourist satisfaction, while affordability perception directly impacts tourist satisfaction but not SDP. The Sobel test validates SDP's mediating role. The findings underscore the importance of sustainability in enhancing tourist experiences, suggesting that tourists value both ethical and environmental aspects of travel, beyond just cost.

High resolution remote sensing for biodiversity assessment and monitoring: A case study of dominant tree species in an old-growth forest

Biodiversity assessment and monitoring in old-growth forests (OGFs) is crucial for their effective management and conservation amongst various natural and human-induced challenges. In the present study, the spatial and temporal species diversity were assessed in the mixed stands of Białowieża Forest (BF), a renowned UNESCO world heritage site recognized as an OGF. The BF has encountered challenges due to pest outbreaks peaking in 2016–2017 with adverse impacts on species composition. Utilizing airborne laser scanning (ALS) and color infrared (CIR) datasets from 2015 and 2019 (prior and following the peak, respectively), 30 variables were extracted and employed as input for the Random Forest algorithm to identify 14 species of broadleaved and coniferous individuals at plot levels (458 plots) within the BF. We calculated biodiversity indices (including α, β, and γ diversity), Importance Value Index (IVI), bivariate scale-dependent density of species, and temporal β diversity indices independently for data acquired from both field observation (FO) and species maps obtained through remote sensing analysis (RSA). The study found no significant differences in α diversity indices between the FO and RSA across the BF, however, notable discrepancies existed in species richness. Limited species detection was attributed to low species frequency and therefore, insufficient reference individuals. Average β and γ diversities from both datasets showed no significant differences. The RSA accurately identified top species and their changes in terms of IVI. Additionally, the RSA explored scale-dependent density changes of broadleaved individuals around conifers. Consistency was observed between FO and RSA in identifying dominance shifts from losses to gains within the BF communities. The comparison of diversity indices obtained from FO and RSA suggests that the RSA provided comparable results to FO in capturing the diversity of dominant tree species within the BF, providing a promising approach for advancing our understanding of forest biodiversity in OGFs.

Between Maroon Tradition and State Law in Jamaica: A Case Study of Challenges to Environmental Governance in a UNESCO World Heritage Site

In the quest for effective environmental governance, the integration of legal and cultural pluralism within conservation strategies emerges as a critical factor, especially in regions marked by rich ethnic diversity and complex historical legacies. This paper explores the symbiotic relationship between state conservation efforts and the engagement of local communities, with a particular focus on the Indigenous Maroon communities in the Blue and John Crow Mountains (BJCMs) of Jamaica. It underscores the imperative of aligning conservation objectives with the aspirations and traditional practices of these communities to foster sustainable ecosystems and safeguard Indigenous autonomy. Central to this discourse is the development of collaborative frameworks that respect and incorporate the legal and cultural dimensions of pluralism, thereby facilitating a co-managed approach to environmental stewardship. This study emphasizes the role of collaboration and trust as pivotal elements in cultivating a mutual understanding of the interdependencies between state law and Indigenous law. This research advocates for a reciprocal exchange of knowledge between the state and community members, aiming to empower the latter with the resources necessary for effective environmental protection while respecting their legal autonomy. This approach not only enhances conservation initiatives overall, but also ensures that these efforts are informed by the rich cultural heritage and traditional ecological knowledge of the Maroon communities. By examining the conservation practices and governance challenges faced by the Maroons in the BJCMs, this paper reveals the nuanced dynamics of implementing state-led conservation laws in areas characterized by cultural and legal pluralism. The findings highlight the necessity for state regulatory frameworks to enable collaborative governance models that complement, rather than undermine, the traditional governance structures of the Maroons. This research contributes to the broader discourse on environmental governance by illustrating the potential of culturally informed conservation strategies to address environmental threats while respecting and reinforcing the social fabric of Indigenous communities.

Role of ice formation mechanisms occurring inside stylolite on limestone tilestone frost susceptibility

Freeze temperature and ice quantity formed inside porous media has been investigated on limestone tilestone samples by Differential Scanning Calorimetry (DSC) measurements. The aim was to determine the role of these stone frost features on limestone damage to Freeze-Thaw (FT) cycles, in relation to the presence of stylolite inside their structure. In fact, the presence of stylolite inside the structure leads to increase locally the pore rate and size, with connected pores. This implies a local increase of ice quantity formed at the surround of stylolite. Damage is thus associated to a heterogeneous nucleation, a rapid growth and ice-front propagation inside pores induced by the presence of stylolite. Specimens exhibiting an increase of quantity of ice formed inside their stylolite – of more than 30% compared to host rock – were damaged by freeze/thaw cycles. Furthermore, stones with freezing temperature lower than the minimum of FT cycles temperature are frost resistant. Finally, low-temperature calorimetry appears to be a practical and cheap method for quickly assessing frost limestone susceptibility. For example, this method can benefit some modest heritage constructions in UNESCO World Heritage site ‘Causse & Cevennes’, made by craftsmen who need to quickly know the frost resistance of the stones they use.

Prevalence and composition of haemosporidians in an avian community from a World Heritage area: Associations with host foraging strata and forest regeneration

Forest regeneration is becoming a powerful tool to combat land conversion which covers 30 % of the Neotropical territory. However, little is known about the effect of forest regeneration on vector-borne diseases. Here, we describe the haemosporidian lineage composition across a successional gradient within an Atlantic Forest bird community. We test whether forest successional stages, in addition to host life history traits affect haemosporidian infection probability. We sampled birds at 16 sampling units with different successional stages between 2017 and 2018 within a forest remnant located in Antonina, Paraná, Brazil. We captured bird individuals using mist-nets, identified them to the species level, and collected blood samples to detect and identify Plasmodium and Haemoproteus lineages based on molecular analysis. We used a Bayesian phylogenetic linear model with a Bernoulli distribution to test whether the haemosporidian infection probability is affected by nest type, foraging stratum, and forest successional stage. We captured 322 bird individuals belonging to 52 species and 21 families. We found 31 parasite lineages and an overall haemosporidian prevalence of 23.9 %, with most infections being caused by Plasmodium (21.7 % of prevalence). The Plasmodium probability of infection was associated with forest successional stage and bird foraging stratum. Birds from the secondary forest in an intermediate stage of succession are more likely to be infected by the parasites than birds from the primary forests (β = 1.21, 95 % CI = 0.11 – 2.43), birds from upper strata exhibit a lower probability of infection than birds from lower foraging strata (β = -1.81, 95 % CI = -3.80 – -0.08). Nest type did not affect the Plasmodium probability of infection. Our results highlight the relevance of forest succession on haemosporidian infection dynamics, which is particularly relevant in a world where natural regeneration is the main tool used in forest restoration.

Hyperspectral identification of travertine state in Huanglong by the PSO-BPNN method

The Huanglong Scenic and Historic Interest Area in China, a UNESCO World Heritage Site, is famous for its large-scale, diverse, intricately structured, and brightly colored surface travertine landscapes. However, severe degradation of the Huanglong travertine formations, such as blackening and algae erosion, has occurred in recent years, necessitating monitoring and identification. We collected hyperspectral reflectance data of the travertine formations in different states and bare ground using a ground-based hyperspectral radiometer (PSR-2500) from ASD company. After conducting a correlation analysis between the hyperspectral reflectance data and the travertine formations, we identified healthy travertine formations, blackened travertine formations, travertine formations affected by algae erosion, and bare ground. The Siamese network method was employed to generate data labels, and the spectral features of the travertine formations were extracted by combining the sensitive bands with pre-processed and reduced data. The PSO-BPNN classifier was developed by optimizing the back propagation neural network (BPNN) using the particle swarm optimization algorithm (PSO). To verify the effectiveness of PSO-BPNN in accurately distinguishing different states of travertine formations, we compared its performance with that of BPNN using three performance indices. Finally, the proposed method was applied to the real-world hyperspectral image data collected by the Micro-Hyperspectral imaging instrument to classify the travertine formations in different states and bare ground. The test set demonstrated good overall performance, with an average overall accuracy (OA) of 0.93, F1-score of 0.92, and Kappa coefficient of 0.97.

Водные объекты в архитектурном и социокультурном пространстве города (на примере средневекового Дербента)

Derbent is the southernmost and the most ancient city of Russia. Extensive archaeological studies confirm the 5,000-year history of the city, which has been a UNESCO World Heritage Site since 2003. Being an ‘open-air museum’, it has many architectural objects that have not yet been fully explored. The article analyses historical and cultural sources. These sources confirm that water objects are a city-forming factor that determined the organisational development and architecture of the city. The purpose of the paper is to analyse the objects related to water resources of medieval Derbent and to identify their significance in relation to the organisation of socio-cultural space. The author pays much attention to the description of urban water bodies that have survived to the present day. The water facilities examined show that the architectural style and materials used for construction created a unified urban environment and were part of the organisational planning of the city's development.

Art Deco Architecture in Pune from the 1940s to the 1960s

Art Deco is a visual arts, architecture, and product design style. It first emerged in Paris in the 1910s, shortly before World War I. This style reached its height in Europe and the United States in the 1920s and early 1930s. The early to mid-1930s saw the emergence of Art Deco architecture in India, which ended in the mid to late 1950s. Indian cities like Mumbai, Pune, Chennai, Jaipur, Jodhpur, and Patiala are home to Art Deco structures. In terms of architecture, the Art Deco movement represented a dramatic departure from the colonial Neo-Gothic/Victorian Gothic model. The pursuit of modernity, multiculturalism, and cosmopolitanism were all reflected in Art Deco architecture. UNESCO declared the Victorian Gothic and Art Deco ensembles of Mumbai (Maharashtra’s capital) a UNESCO World Heritage Site in June 2018. Nevertheless, Pune City’s Art Deco buildings are not recognized as heritage buildings or documented. The study involved photographic documentation of Art Deco buildings in Deccan, Swargate Prabhat Road, Bhandarkar Road area of Pune. This paper examines the various motifs and their underlying symbolism that can be seen in Pune’s Art Deco buildings. The results of this study show that the Art Deco buildings in Pune are now on the verge of extinction due to the age of the building, structural deformities and lack of awareness of the conservation of this historical heritage. The art deco features on the elevations of many buildings have been hidden/erased by renovation and commercial hoardings.

Evaluation of Calcarenite Degradation by X-ray Photoelectron Spectroscopy Analysis inside the Rupestrian Church of San Pietro Barisano (Matera, Southern Italy)

We report on the XPS analysis of degraded surfaces inside San Pietro Barisano, the rupestrian church carved into the calcarenite rock of ancient Matera, which has been a UNESCO World Heritage Site since 1993. As reported in previous works, the “Sassi” district and the park of rupestrian churches were available as open laboratories for the National Smart Cities SCN_00520 research project dedicated to the sustainable recovery of this remarkable architectural heritage. In that context, XPS functionality was shown to reside in the possibility of analyzing surfaces by feasible sampling, acquiring spectra without any preliminary sample treatment, and processing data using a well-established curve fitting procedure. The obtained results allowed us to identify the degradation products of the investigated surfaces, thus contributing to defining a diagnostic framework for subsequent actions. Accordingly, the samples here considered, collected from the internal wall surfaces of the church, were all analyzed in comparison with the reference calcarenite, and the XPS results were evaluated as a function of local environmental factors and the historical context of the church itself. The final aim was to provide, for each sample, the most representative indicator(s) of biotic and/or abiotic degradation for reliable use, in a multidisciplinary context, in planning care interventions for building heritage.

Shift away from Nile incision at Luxor ~4,000 years ago impacted ancient Egyptian landscapes

Although the Nile is one of the largest rivers in the world and played a central role in ancient Egyptian life, little is known about its response to climatic change during the Holocene. Here we present a framework for the evolution of the Egyptian Nile, demonstrating how climatic and environmental changes have shaped the landscape of the Egyptian Nile Valley over the past 11,500 years, including the civilization of ancient Egypt (~5,000 to 2,000 years ago). Using data from over 80 sediment cores drilled in a transect spanning the Nile Valley near Luxor, pinned in time by 48 optically stimulated luminescence ages, we reconstruct the dynamics of the Nile River during the Holocene in the vicinity of UNESCO World Heritage sites such as Karnak and Luxor temples. According to our reconstruction, valley incision occurred from the start of the record until approximately 4,000 years ago and then rapidly shifted to massive floodplain aggradation. We argue that this relatively abrupt change in the riverine landscape near Luxor from the Middle to Late Holocene was linked to a shift towards a drier regional hydroclimate around this time. Such a dramatic change in river sediment dynamics could have had local agro-economic consequences.

Interactive 360° media for the dissemination of endangered world heritage sites: the ancient city of Palmyra in Syria

Since the onset of conflict in Syria in 2011, several heritage sites have suffered partial or complete destruction. The ancient city of Palmyra, a UNESCO World Heritage Site since 1980, was placed on the List of World Heritage in Danger in 2013, alongside five other Syrian heritage sites. Between 2015 and 2017, Palmyra experienced the loss of nearly 40% of its historic buildings and landmarks. The site’s remote location and ongoing armed conflict pose additional challenges in accessing and preserving it.This paper introduces an interactive online platform employing 360° media to document and disseminate information about the world heritage site of Palmyra. The platform contributes to the safeguarding process of Palmyra, facilitating public engagement and interaction with the site. It also has potential applications for other sites in Syria and beyond. The platform allows users to explore both archival and current information of damaged historical monuments and buildings, revealing their layered histories before and after demolition. Employing interactive 360° media, similar to applications like Google Street View, the platform offers a reality-based digital environment. Users can virtually move into different buildings or follow specific pathways within the site, accessing archival information and documentation about particular monuments and buildings along their journey.This project serves as a unique informational resource for decision-makers and policy planners, aiding in the understanding of the site and the development of relevant strategies and recommendations. It also proves beneficial as an educational tool. The collective understanding fostered by this platform is expected to positively influence post-conflict restoration and reconstruction plans, making it an invaluable asset for research and educational purposes.

Estimating tourism losses due to COVID-19 Pandemic: The case of Puerto Princesa underground river, Philippines

This study estimated the economic losses of Puerto Princesa Underground River (PPUR) caused by the COVID-19 pandemic. The PPUR in Puerto Princesa City, Palawan, Philippines is part of the Puerto Princesa Subterranean River National Park (PPSRNP) and is recognized as a UNESCO World Heritage Site. The lost tourist arrivals caused declining PPUR revenues, affected the local economy, and posed a potential threat to PPSRNP’s environment. The Seasonal Autoregressive Integrated Moving Average (SARIMA) was used to estimate the revenue and tourist arrivals while the Simple Exponential Smoothing (SES) was used to estimate PPUR expenses. The results revealed that the PPUR lost Php 172,997,905.00 which was attributed to the foregone 281,441 international tourists and 335,687 domestic tourists from 2020-2021. The PPUR management could expect Php 2,230.56 as revenue per potential tourists, an increase in revenue of roughly Php 96.7 million, an increase in international tourist arrivals, and a decrease in domestic tourist arrivals from 2022-2024 had there been no pandemic. Thus, PPUR management should forge active collaboration with different stakeholders for sustainable operation in times of economic disaster.

An ecotourism suitability index for a world heritage city using GIS-multi criteria decision analysis techniques

The concept of ecotourism has experienced a significant surge in popularity over the past two decades, primarily driven by the multitude of adverse impacts associated with mass tourism. The objective of the study was to develop a comprehensive ecotourism suitability index to guide policymakers in implementing tourism development policies. Given the considerable appeal of the study area to both local and international tourists, it is essential to conduct a systematic evaluation to pinpoint suitable areas for ecotourism development. This necessity arises from the study area's placement within a fragile ecosystem and its proximity to a UNESCO World Heritage site. We employed a Geographic Information Systems (GIS) integrated environment coupled with a fuzzy Multi-Criteria Decision Analysis (MCDA) methodology. The GIS-MCDA integrated framework leverages the Analytic Hierarchy Process (AHP) and a weighted linear combination that seeks to amalgamate many features and criteria to assess ecotourism potential by integrating 20 criteria into six separate categories: landscape, topography, accessibility, climate, forest and wildlife, and negative factors. Weights were allocated to each criterion and factor based on the expert's opinions of their impact on the development of ecotourism. The final ecotourism suitability index comprised five unique classes: very high, high, moderate, less, and not suitable. Results reveal that out of the total areas, 45.4 % (259 km2) are within the high and very high suitable classes. The sensitivity analysis suggested that ecotourism potentials are more favorable to forest and accessibility variables. The generated index can be utilized as a road map since validation verified a 64 % accuracy. Given the dearth of earlier research, this study provides vital support for the development of sustainable ecotourism projects in the study area.

Expected direct costs of an oil spill in a UNESCO World Heritage area in New Zealand

AbstractFiordland National Park is a UNESCO site located in the remote, southwest of New Zealand's South Island, which attracts hundreds of thousands of visitors every year. One of its leading attractions is Milford Sound. An oil spill in this area could not only impact the industries that operate in Milford Sound but also impact all of the park. To improve the knowledge base about this area in regard to oil spills and policies regarding ship visitation, this study aimed to estimate the costs of clean‐up, impacts to fisheries, tourism, recreation and the wildlife/environment under three oil spill scenarios in Milford Sound. Minimum costs are estimated at NZD 140–154 million. These results demonstrate the need for proper planning and response measures, and appropriate domestic and international policies to help minimise the potential damages that may occur in the event of an oil spill in a remote and pristine area of New Zealand.

Assessing the Impact of the Türkiye February 2023 Earthquakes on Cultural Heritage Sites: A Multi-Disciplinary Approach Utilizing ARIA Maps and Social Media Collaboration

Abstract. The earthquakes that occurred in our country on February 6, 2023, significantly damaged and destroyed cultural and historical assets. The Habib-i Nejjar Mosque in Antakya and other important historical sites suffered significant damage. This study provides a comprehensive account of the post-earthquake efforts carried out by volunteers from various disciplines, including archaeology, cartography, space sciences, and architecture, using social media platforms. The volunteers created an extensive database for cultural and archaeological sites in all 11 provinces that were declared disaster zones. This database made it easier to conduct a thorough evaluation of the damage. The database was augmented with surface displacement data, enabling an analysis of damage levels with the exactitude facilitated by the gathered information. The utilization of the Advanced Rapid Imaging and Analysis (ARIA) maps was pivotal in this study. The maps, created through partnerships between NASA and different space agencies, offer intricate satellite imagery and analysis of surface displacement. This is essential for evaluating the effects of earthquakes on cultural heritage sites. The utilization of ARIA maps in this study facilitated an accurate assessment of the seismic impact on cultural and historical resources. Additionally, Sentinel 1 images are used to generate displacement maps with the use of the LICSAR tool and the SBAS method. The study examined the state of about 1500 cultural heritage sites in 11 provinces in the aftermath of the earthquake. The report incorporated data from media coverage and input from relevant parties present at the scene, providing a thorough assessment of the situation following the disaster. For instance, the research revealed substantial shifts at prominent locations, like the UNESCO World Heritage site of Arslantepe in Malatya. This site experienced a displacement of over one meter towards the south and 75 cm towards the west, along with a subsidence of approximately 10 cm in the surrounding area. Furthermore, the study presented a visual representation that depicted the quantity of impaired cultural heritage sites in every province, providing a comprehensive evaluation of the impacted cultural and archaeological resources. This comprehensive strategy not only emphasized the magnitude of harm to cultural heritage but also emphasized the significance of interdisciplinary cooperation in disaster response and heritage preservation.

Ecotoxicological Assessment of Microplastics and Cellulose Particles in the Galápagos Islands and Galápagos Penguin Food Web.

Microplastic pollution threatens some of the world's most iconic locations for marine biodiversity, including the remote Galápagos Islands, Ecuador. Using the Galápagos penguin (Spheniscus mendiculus) as a sentinel species, the present study assessed microplastics and suspected anthropogenic cellulose concentrations in surface seawater and zooplankton near Santa Cruz and Galápagos penguin colonies (Floreana, Isabela, Santiago), as well as in penguin potential prey (anchovies, mullets, milkfish) and penguin scat. On average, 0.40 ± 0.32 microplastics L-1 were found in surface seawater (<10 μm; n = 63 L), while 0.003, 0.27, and 5.12 microplastics individual-1 were found in zooplankton (n = 3372), anchovies (n = 11), and mullets (n = 6), respectively. The highest concentration (27 microplastics individual-1) was observed in a single milkfish. Calculations based on microplastics per gram of prey, in a potential diet composition scenario, suggest that the Galápagos penguin may consume 2881 to 9602 microplastics daily from prey. Despite this, no microplastics or cellulose were identified in 3.40 g of guano collected from two penguins. Our study confirms microplastic exposure in the pelagic food web and endangered penguin species within the UNESCO World Heritage site Galápagos Islands, which can be used to inform regional and international policies to mitigate plastic pollution and conserve biodiversity in the global ocean.
