AbstractThe article presents recent capabilities of active and passive earth observation sensors along with related processing image chains, for monitoring UNESCO World Heritage properties. Exceptional heritage sites and landscapes are found in dynamic environments, whereas both anthropogenic and natural changes are observed. The use of radar and optical satellite imageries can be used as a systematic observation tool for stakeholders, to map drastic or slowly driven landscape changes towards the better protection and management of these sites and their surrounding areas. The study presents the results from the analysis of the European Copernicus Sentinel-1 and Sentinel-2 satellite images over two broader areas in the Eastern Mediterranean basin that hold important UNESCO World Heritage properties. Initially, a recent strong earthquake of a 6.7 magnitude scale in the Aegean Sea is studied using radar Sentinel-1 images. These radar images were processed through the Hybrid Pluggable Processing Pipeline (HyP3) cloud platform for analyzing both significant changes of the VV (vertical transmit, vertical receive) and VH (vertical transmit, horizontal receive) backscattering signal as well as through an Interferometric Synthetic Aperture Radar (InSAR) analysis. Then, long-term changes in Cyprus during the last two decades are monitored by a Sentinel-2 image compared to the European Corine Land Use Land Cover data of 2000. These changes are mapped after a supervised classification process using the random forest (RF) classifier. The overall results demonstrate that the recent developments of the space sector in all its segments (resolution of the sensors, the capacity to storage in the cloud, processing advancements and open-access datasets and tools) can be beneficial for monitoring UNESCO World Heritage properties.

The Relationship

AbstractThe local and extra-regional (national and transnational) stones mainly used as building and ornamental materials in the historic centre of Urbino (UNESCO World Heritage List) were unravelled through a detailed geological and petrographic study. The types of building stones used in the past for the development of an urban centre were mostly affected by the availability of suitable geomaterials in the surrounding areas. For this reason, the stones found in the historical buildings of Urbino generally come from the local sedimentary formations (mostly limestones) belonging to the Umbria–Marche–Romagna Succession Auct., which crops out in the Northern Marche Apennines. Only some ornamental highly prized stones used for monuments and decorations come from both extra-regional Italian areas (Alps, other sectors of the Northern Apennines) and foreign countries (France, Egypt). A brief description of the Northern Marche geology was also reported to exactly match the local provenance of the stones, so highlighting the relationship between the territory and the architecture of Urbino. Because of obvious conservation reasons, no samples were collected from buildings or monuments and only autoptic observations, together with a detailed historical and bibliographic research, were carried out to identify the different materials and the provenance areas. Besides the availability of the local sedimentary rocks, we emphasised how the choice of the building and ornamental stones could have been also influenced by the historic period and artistic style, aesthetic features, economic and social importance of the building and/or monument and the relationship to some distinguished personality (e.g., Pope Clemente XI). An open-air stone itinerary across significant places (10 stops and additional sites and monuments in the urban area) is finally proposed for the best fruition of the geological and cultural heritage of Urbino, also aimed at geotourism development.

In 2015, Kosovo tried to join UNESCO and failed by three quotes. Is Kosovo ready for its UNESCO membership? At least for its national architectural heritage, this question is to answer with no. The intensively discussed issue of the medieval monuments of Kosovo inscribed as UNESCO World Heritage by Serbia and Montenegro before the declaration of independency in 2008 and their further management through Kosovo is just one aspect. More troubling is that the rather young state not yet could establish sufficient structures to gain a systematic inventory of its monuments, sites and historic ensembles, nor to extract a tentative list for UNESCO out of such an encompassing inventory. This article intends to clarify the definitions of World Heritage, the institutions and NGO’s involved, the mechanisms and philosophies behind. What is the urgent homework for Kosovo? Which national and international groups of experts Kosovo has to name and make responsible for the systemic inventory of its architectural heritage and for creating a tentative list? What is the role and importance of ICOMOS in that process? Which other stakeholders have to be Identified and educated towards that issue?</p><p>Based on such general considerations the author tries to design finally a preliminary tentative list for the architectural heritage of Kosovo. Hence, not the list itself is of importance but the discussion of the pro and contra arguments for single candidates.

And Diffusion

The Province of Belluno is home of great human and landscape quality and of the beautiful Dolomites, UNESCO World Heritage. How experiences of contemporary architecture fit and how are promoted in this context? It can be said that contemporary architecture does not attract a big audience. This is despite the constant efforts by various bodies and associations to promote its diffusion and development through competitions, conferences, workshops and case studies. In the Belluno region, apart from the extraordinary extant historical heritage, there are widespread examples of new architecture known as “false alpine models” or architecture that has erroneously become typical of the Province’s image. This is the reason why this new architecture with its range of peculiarities is widely reiterated, from north to south of the area. Even though buildings of this type lack any real ties with history or tradition, they find widespread approval by institutions and commissions. They are the result of repetitive practices deriving from constraints imposed by local regulations and a limited aptitude in the use of contemporary language of architecture. Even if the barometer of the vitality of contemporary architecture in the region of Belluno is rather lukewarm, dampened by cultural resistance and by regulatory constraints affecting its growth and diffusion, there is no lack of experiences, initiatives and achievements. The latter is evidence of the fact that where research and the use of contemporary languages are accompanied by the opinions of enlightened patrons, good architecture is born, which find space in the arena of national and international architectural debate. Examples of good architecture, even though limited in number, are distributed across the Province and constitute heritage and the focus for promoting and consolidating the growth and dissemination of contemporary architecture throughout the area.

Chapter 5 analyses the evolving conception and protection of landscape in the World Heritage Convention. First, it traces the development of landscape protection from its early conceptual dependency on nature, to the incorporation of ‘cultural landscapes’ within the Convention’s scope in 1992. It then discusses the typology of cultural landscapes, issues of representativeness and the implications of the Word Heritage system for landscape protection globally, as well as locally. In this regard, a number of cases are analysed which, on the one hand, support the World Heritage Convention’s instrumental role in landscape governance, but which on the other, highlight the problems involved in ascribing World Heritage status to living landscapes from a spatial justice perspective.

Accurate burned area information is needed to assess the impacts of wildfires on people, communities, and natural ecosystems. Various burned area detection methods have been developed using satellite remote sensing measurements with wide coverage and frequent revisits. Our study aims to expound on the capability of deep learning (DL) models for automatically mapping burned areas from uni-temporal multispectral imagery. Specifically, several semantic segmentation network architectures, i.e., U-Net, HRNet, Fast-SCNN, and DeepLabv3+, and machine learning (ML) algorithms were applied to Sentinel-2 imagery and Landsat-8 imagery in three wildfire sites in two different local climate zones. The validation results show that the DL algorithms outperform the ML methods in two of the three cases with the compact burned scars, while ML methods seem to be more suitable for mapping dispersed burn in boreal forests. Using Sentinel-2 images, U-Net and HRNet exhibit comparatively identical performance with higher kappa (around 0.9) in one heterogeneous Mediterranean fire site in Greece; Fast-SCNN performs better than others with kappa over 0.79 in one compact boreal forest fire with various burn severity in Sweden. Furthermore, directly transferring the trained models to corresponding Landsat-8 data, HRNet dominates in the three test sites among DL models and can preserve the high accuracy. The results demonstrated that DL models can make full use of contextual information and capture spatial details in multiple scales from fire-sensitive spectral bands to map burned areas. Using only a post-fire image, the DL methods not only provide automatic, accurate, and bias-free large-scale mapping option with cross-sensor applicability, but also have potential to be used for onboard processing in the next Earth observation satellites.

Significant Difference

The Wadden Sea ecosystem is unique in many respects from a biological perspective. This is one reason why it is protected by national parks in Germany and by its designation as a UNESCO World Heritage Site. In biology didactics, there are only a few studies that focus on the Wadden Sea. This work investigates students’ word associations with the two stimulus words “national park” and “UNESCO World Heritage Site”. The survey was conducted among students living directly at the Wadden Sea and among students from the inland. The analysis of the identified associations (n = 8345) was carried out within the framework of a quantitative content analysis to be able to present and discuss the results on a group level. A statistically significant difference was found between the two groups. Overall, results showed that the students made subject-related associations as well as a large number of associations to both stimulus words that could be judged as non-subject-related. In some cases, a connection with the region of residence could be found, but this was not generally the case. Even students’ immediate residential proximity to the Wadden Sea is no guarantee that they have knowledge of the two considered protection terms.
