Archaeological sites located on the edge of growing cities often struggle to reconcile heritage protection with rapid development. To understand this tension, we examined a 50.83 km² zone around the Western Han Imperial Mausoleums in the Qin-Han New District. Using Landsat images from 1992, 2002, 2012, and 2022, this study applied supervised classification, land-use transfer matrices, and dynamic-degree analysis to trace three decades of land-use change. From 1992 to 2022, built-up land expanded by 29.85 percentage points, largely replacing farmland, which shrank by 35.64 percentage points and became fragmented. Forest cover gained a modest 5.78 percentage points and migrated eastward toward the mausoleums. Overall, urban growth followed a “spread–integrate–connect” pattern along major roads. This study interprets these trends through five interrelated drivers, including policy, planning, economy, population, and heritage protection, and proposes an integrated management model. The model links archaeological pre-assessment with land-use compatibility zoning and active community participation. Together, these measures offer a practical roadmap for balancing conservation and sustainable land management at imperial burial complexes and similar urban fringe heritage sites. Full article

The Western Regions during the Han and Tang Dynasties served as a significant cultural intersection along the Silk Road, with stupas acting as core architectural forms of Buddhist dissemination, embodying religious, cultural, and artistic evolution. This study is a research article based on typological analysis, integrating historical documents and archaeological site data to explore the stylistic evolution of stupa architecture in the Western Regions during the Han and Tang Dynasties, revealing the changes in religious beliefs and the process of cultural adaptation and integration of Buddhism in a multicultural context. The study demonstrates that the distribution of stupas shifted from being concentrated in areas such as Shanshan and Shule during the Han Dynasty to expanding across a wider region during the Wei, Jin, and Northern and Southern Dynasties, eventually forming a Gaochang-centered pattern in the Tang Dynasty. Architectural styles evolved from the simplicity of domed stupas to diversification and then to standardization. The number of niches increased from none to many before decreasing again, while the proportions of the stupa bases gradually increased. This evolution highlights the transition of stupa styles from a singular form to diversification, eventually achieving standardization in the Tang Dynasty. This transformation not only reflects the optimization of the temple layout, gradually shifting from a stupa-centered to a Buddha hall-centered structure, but also illustrates the evolution of stupas from symbols of the Buddha’s tomb to carriers for Buddha statues and ultimately to representations of the Mount Sumeru cosmological concept. This transition also mirrors the shift in Buddhist beliefs, evolving from Theravāda to Mahāyāna Buddhism and then returning to Theravāda practices. This not only facilitated the regionalization of stupa forms and the integration of artistic styles but also provided a significant medium for cultural exchange between China and the West.

Kruger National Park is one of the most well-preserved national parks in the Southern Hemisphere. However, cases of visitors participating in deviant leisure practices (DLPs) are reported in the park, threatening the sustainability of sensitive tourism resources. Adopting a deviant leisure lens, this study assesses the extent to which visitors participate in DLPs at the Kruger National Park (KNP) and the causes of those behaviours. Variables adopted from the KNP codes of conduct for visitors were used to measure the DLPs based on the visitors’ perception of the park. A quantitative survey design, with a sample size of 237 respondents, assessed respondents’ participation in DLPs. The study results reveal that visitors participate in DLPs at KNP. However, the level at which visitors participate in DLPs is inconsistent. The most common DLPs by visitors are getting close to animals to take pictures and driving off-road to see animals. The reasons for visitors participating in these behaviours are the need to create memorable experiences and being in “holiday mode”. The least violated codes of conduct in the park are picking up archaeological objects to keep them as souvenirs and bringing prohibited items into the park without declaring. This study is significant as it is the first to investigate the extent visitors participate in DLPs using a self-reported instrument. Based on the results, park managers may develop effective strategies to reduce the number of visitors getting close to animals to take pictures and driving off-road to observe animals at close range.

This field statement reviews the sources, issues, approaches, and missions of Dunhuang architectural studies from 1926 to the present. The studies of Dunhuang architecture constitute a subfield at the intersection of Dunhuang studies, Silk Road archaeology, and studies of Chinese architectural history. Dunhuang architectural studies primarily investigate three corpses of materials, i.e., the images of architecture represented in mural paintings, the cave typology, and the timber-framed façade screening the caves. This study outlines the three phases in which scholarly concerns evolved from images to their material carriers, from forms to spaces, and from disciplinary to interdisciplinary. The first phase, 1926–1950, features Chinese, Japanese, and German scholars’ early explorations of the images of architecture, mostly based on photographic reproductions of murals and timber façades. They established connections between the Dunhuang materials and the modern studies of art and architectural histories. In the second phase, 1950–2000, scholars, mainly Chinese, explored the majority of the primary materials and managed to establish a research framework for research that is still valid today. Some others conducted refreshing studies from the perspective of spatial conception. The third phase, from 2001 to the present, witnesses the emergence of new materials, perspectives, and technologies, which stimulate interdisciplinary and innovative studies of the Dunhuang materials. Finally, this review reflects on the received conceptions the field has brought us to consider the architecture of a Dunhuang cave temple and points out issues of space for future investigations.

This study sheds light on the origin and trade routes of early red coral artifacts found in Xinjiang, primarily dating to the Han and Jin dynasties. The red coral relics examined, excavated from the Shengjindian cemetery of the Western Han Dynasty in Turpan, offer critical insights into the material’s provenance and its introduction to this pivotal region along the ancient Silk Road. Advanced gemological, mineralogical, and geochemical analyses—utilizing computed tomography (CT), laser Raman spectroscopy, and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)—has revealed distinctive features. These include red coloration, a waxy luster, concentric ring structures in cross-section, and calcareous composition, identifying the coral as Sardinian (Corallium rubrum), likely originating from the western Mediterranean region. The findings carry significant archaeological implications. Red coral first appears in the archaeological record in Xinjiang during the Western Han period, facilitated by the thriving Silk Road trade and the expanding influence of Buddhist culture. This study not only confirms the Mediterranean origin of these artifacts but also highlights their integration into the cultural and economic networks of ancient Xinjiang, underscoring the significance of early long-distance trade and cultural exchange.

Archaeological complexes are characterized by different degrees of damage related to both natural events and anthropogenic triggers. The damage may be assessed through direct observation or remotely acquired data. Here, we present a morphometric analysis of a digital surface model (DSM) obtained from an orthophotogrammetric survey at the Sanctuary of Pachacamac Archaeological Complex, Peru (2nd to 16th centuries AD), which includes temples, enclosures, huacas, and roads. We determine different morphometric parameters to quantitatively describe the architectural layout of the site. These are aspect, slope, range, and topographic position index (TPI). We applied a modified TPI classification to measure the different degrees of preservation of the walls of the archaeological structures and recognize preserved, partly preserved, partly destroyed, and destroyed walls. The walls of the site show different degrees of preservation related to the damage associated with earthquakes and El Niño destructive events. The architectural layout of the archaeological site is defined by NW-SE and NE-SW striking walls. This is due to buildings constructed along the two main NW-SE and NE-SW striking roads of the Qhapac–Ñan road network. The prevailing El Niño wind direction may also explain the observed architectural layout. Morphometric parameters can be used to estimate the degree of conservation of archaeological sites. Our analytical approach can be applied to modern buildings damaged by natural events or human activities. Full article

In the past, the Silk Road was a vital trade route that spanned Eurasia, connecting East Asia to the Mediterranean Sea. The genus Prunus, belonging to the Rosaceae family and encompassing plums, peaches, apricots, cherries, and almonds, thrived as human travel along the Silk Road increased. The majority of fruits within this genus, whether wild or cultivated, are naturally sweet and easily preserved by drying for storage and transport. The interaction along the Silk Road between wild populations and diverse varieties of Prunus fruits led to the development of various hybrids. This article provides a summary of archaeological findings related to prominent Prunus fruits such as peaches, apricots, plums, cherries, and almonds, shedding light on their evolutionary history, genetic diversity, population structure, and historical dynamics crucial for species conservation. The origins of biodiversity may involve factors like migration of pre-adapted lineages, in situ variation, or the persistence of ancestral lineages. Furthermore, climate change is affecting spatial genetic patterns and potentially further threatening rare Prunus species. Evaluating the scope and composition of genetic diversity within germplasm collections is essential for enhancing plant breeding initiatives and preserving genetic resources in this changing context. From a molecular point of view, techniques such as genome-wide association studies (GWASs) and the identification of quantitative trait loci (QTLs) and genes responsible for phenotypic changes in cultivars and germplasm collections should be of great interest in these breeding programs, while genomic estimated breeding values (GEBVs) derived from genome-wide DNA polymorphism information can facilitate the selection of superior genotypes.

Given that spatial accessibility to tourist resources is crucial for tourism development, this study analyzes the role of the distance between tourists and archaeological sites in the Dobrogea region of Romania. This study highlights the impact of road distance in the valorization of the main archaeological sites in the chosen area, the results obtained providing information on the main parameters of archaeological resources in achieving tourism success. These data will be important clues in the future design of plans for the valorization of those archaeological sites not yet valorized from the tourist point of view. Spatial data modeling was performed using specific Geographic Information Systems tools, which allowed us to extract the necessary information. By corroborating the results of the geospatial analysis with the statistical ones, we were able to draw conclusions regarding the tourist behavior in the region and the decision factors of tourists in visiting the ancient or medieval ruins in Dobrogea. Our analysis shows a significant correlation between the road accessibility of archaeological sites and their tourist attractiveness, with a particular influence of their location in relation to the main tourist areas of interest in the region. The study area has a rich history that has left behind a high density of ancient fortresses, citadels, and cities, which are relatively underutilized for tourism. Heritage tourism has thus lagged behind coastal tourism, which attracts the highest number of tourists in the country. A better knowledge of the factors that favor the development of heritage tourism is needed in order to expand the region’s tourist offer. Our recommendations aim to improve the accessibility and attractiveness of these archaeological sites by investing in essential infrastructure, developing sustainable transportation policies and specific tourism facilities, and implementing a regional strategy to enhance and protect them, which will ultimately increase their contribution to local economies.

The Silk Road connected the east of Iran to the western world. Roue city is close to the Road. Six glass samples from Roue were classified on the basis of morphology, archaeological context and compositions. The samples were analysed by means of XRF and Raman spectroscopy and two specific groups, namely Roue type 1 and Roue type 2, with close composition to high alumina plant-ash glass in circulation from the 6th to 10th centuries CE in Mesopotamia, Iran and Syria, were identified. The simultaneous occurrence of two types of glass in the excavated layers shows that the house was inhabited in the early Islamic period. Colours (black, amber-green, light and aqua blue) were produced mainly by the amount of iron and sulphur ions required for the amber chromophore and copper ions for the blue colour and the controlling of reducing conditions in the furnace.

The Bir el-Umdan cistern, a prominent archaeological site in the Judean Desert, is one of the largest and best preserved water systems in the region. Hewn in chalk, the cistern area measures 114 m² and has a ~700 m³ volume. Two massive columns, each with a base diameter of 2.5 m, support the ceiling within the cistern’s interior. This impressive structure is estimated to date back to the Hellenistic to Late Antiquity periods based on its architectural characteristics. Historical records indicate that the cistern was documented on 19th-century maps but disappeared from the 1935 and 1943 British Mandate maps. Its reappearance on the 1967 Survey of Israel map includes an upstream road disconnecting the cistern from its natural drainage basin. Despite its renovation in the 2010s, the cistern’s water supply remains limited due to its reduced catchment area, which now constitutes only 25% of its original size. Runoff coefficients calculated for the cistern’s drainage basin are relatively low (1.4% to 8.1%) compared to other desert regions. We analyzed the 21st-century runoff coefficient and recurrence interval over the original drainage basin (0.12 km²) to estimate the water volumes in antiquity. Our analysis suggests that using an 8.1% runoff coefficient, the estimated water volume is 806 m³, implying a cistern overflow every 6–7 years. A more conservative estimate using a 5% runoff coefficient yields a water volume of 500 m³ and a 15-year recurrence interval. Sediment analysis reveals that silt particles dominate the sediment accumulated in the cistern and its upstream sedimentation basins. The consistent grain size distribution throughout the system indicates rapid water flow during flood events. Reconstructing the sedimentation history is challenging due to potential maintenance and possible dredging and cleaning operations. Full article

In this paper, some of the basic information on Ground-Penetrating Radar (GPR), its applications (especially in the field of civil engineering) and limitations are presented. As a non-destructive technique, GPR is a powerful tool for the investigation of structures and structural members, roads, geological layers, archaeological sites and many more. The technology is based on electromagnetic radiation in the UHF/VHF range (10 MHz to 3 GHz). The choice of the frequency depends on the intended use, depth and size of the target and medium where the target is located. Joined with other testing methods (ultrasound method, dynamic methods with forced or ambient vibrations, electrical conductivity testing, etc.), GPR can provide a deep insight into the investigated object. However, like many other non-destructive methods, the choice of input parameters may affect the results. In this regard, a case study presented in this paper demonstrates not only different applications of GPR in civil engineering but also the determination (calibration) of one of those input parameters: the dielectric constant of glued laminated timber. The challenge here was not only to investigate the influence of the direction of measurements with regards to the direction of the fibers but also to acknowledge the contribution of the test antenna used during testing and dielectric constant calibration.

Regions densely populated with archaeological monuments pose significant challenges for construction investors and archaeologists during the planning stages of major construction projects. Recognising the archaeological potential of these areas is crucial for planning effective rescue excavations, which have become a standard procedure in construction. This study explores the utility of non-invasive prospection techniques, including artefact field surveys, multispectral imaging, and magnetic surveys, in assessing the area chosen for the I/16 Slaný–Velvary road construction. We specifically focused on the contributions these methods make towards understanding the archaeological context of the proposed construction site. The findings from the magnetic survey were compared with the results of actual archaeological excavations. Through manual visual analysis and statistical spatial correlation, we assessed the effectiveness of the magnetic survey. The ability of magnetic survey to locate different types of archaeological objects proved to be dependent on various factors. The variability of the environmental setting, particularly pedological and geological conditions, is essential. However, the modern anthropogenic impact and the very nature of individual archaeological objects, especially their dimensions, also play an essential role. Full article

Natural events (floods, earthquakes, landslides, etc.) may significantly damage archaeological sites, and therefore reducing their exposure to such events represents a priority for protective and conservation activities. The archaeological Sanctuary of Pachacamac (SP; 2nd–16th century CE; Peru) covers an area of 465 hectares and includes roads, enclosures, huacas with ramps, temples, and palaces located along the central coast of Peru. This area is affected by heavy rain and winds related to the El Niño–Southern Oscillation and to intense solar radiation. We use a 30 cm resolution Digital Surface Model obtained from orthophotogrammetric data and perform a morphometric analysis using geomorphological, hydrological, and climatic quantitative parameters. Our aim is to identify the zones exposed to water flow or stagnation during rainfall, as well as the exposure to winds and solar radiation. The calculated parameters are subsequently processed with an object-based image analysis approach to identify areas with higher climate exposure. We show that the SP architectural layout controls the exposure to water stagnation or flow in the form of rainfall, whereas exposure to wind and solar radiation mainly depends on the topography of an area (e.g., the presence of hills and plains). The methodological approach proposed here may be applied and extended to other archaeological sites. Full article

Famous for Taklimakan, the world’s second largest sandy desert, the Tarim Basin in Xinjiang has long attracted researchers from various fields to investigate its paleoenvironment and antiquity. The southern part of this basin is an ideal region in which to investigate the interactions between humans and the environment due to its fragile habitat and prosperous ancient civilizations. However, the lack of direct radiocarbon dating data has caused the chronologies of some of the archaeological sites to be debatable, which hinders our ability to reconstruct historical patterns of human activity and further understand, in a coherent manner, their interaction with the environment. This study reports 25 new radiocarbon dates acquired from ten undated archaeological sites in the southern Taklimakan Desert in order to refine their chronologies. Based on this, a radiocarbon dataset was established to reveal the trajectory of human activity with the support of Bayesian chronological modeling. The results indicate a two-millennium continuous flourishing of the local society since the beginning of the first millennium BCE, as well as a peak of human activity during the Tang Dynasty (618–907 CE). The distinct trajectory of human activity in the southern Tarim Basin revealed by this study provides a solid foundation for further assessments of human–environment interaction in the Tarim Basin and along the Silk Road.

Anthropogenic and environmental processes present unique challenges for preserving cultural heritage in North Africa. Large parts of this region are characterised by unfavourable arid and semi-arid conditions and rapid changes to the landscapes caused by heightened regional development (e.g., urban expansion, road building, agricultural intensification, and socio-political conflicts). As a result, we are facing a fast-paced disappearance of heritage sites in regions that are still poorly understood. Following this, the utilisation of Earth observation data through aerial photographs and satellite imagery has emerged as an unmatched tool in the exploration of endangered archaeological heritage. Drawing on this context, this paper underscores the critical significance of incorporating digital research methods, such as remote sensing, GIS, or cartographic analysis, to ensure the evaluation and (digital) preservation of the historical sites along these vulnerable areas. Furthermore, our study seeks to provide new insights into data management and dissemination, fostering open research practices within North African archaeological research. Full article
