Introduction: Sporotrichosis is a chronic infectious mycosis caused by traumatic implantation of Sporothrix spp., which poses a significant challenge to public health because of its zoonotic nature. It affects humans and other animals, particularly cats. This study investigated epidemiological trends and spatial distribution of feline sporotrichosis in Espírito Santo between 2017 and 2022. Methods: This study collected diagnostic data on sporotrichosis from the Veterinary Pathology Laboratory and Center for Infectious Diseases in Espírito Santo from 2017 to 2022. Statistical analyses were performed using STATA and spatial analyses were performed using ArcGIS software to create maps and identify hotspots. Kernel density estimation and directional mean statistics were applied to visualise the disease concentration and transmission trends. Results: The results showed a significant increase in feline sporotrichosis cases in Espírito Santo from 2017 to 2022, with hotspots identified in urban and densely populated areas. Anchieta, Aracruz and Vila Velha reported the highest numbers of cases. Spatial analysis indicated a spread towards the central and northern coastal regions. Conclusion: This study highlights the growing threat of feline sporotrichosis in Espírito Santo, Brazil, particularly in densely populated urban areas. This underscores the urgent need for comprehensive public health strategies that address urbanisation, human–animal interactions and managing stray cat populations. Effective control measures and enhanced surveillance are crucial to mitigate the spread of this zoonotic disease. Importantly, this study provides valuable insights into the epidemiology of sporotrichosis in Brazil and offers a framework for other regions identified as emerging hotspots that face similar challenges.

- Abstract
The Ningxia region in Northwest China, a significant grain-producing area, heavily relies on the Yellow River for agricultural irrigation. Maintaining the ecological health of the Yellow River is crucial due to its role as the primary water source. This research comprehensively assessed heavy metal (HM) levels in surface water and sediments within the Ningxia section of the Yellow River basin. It specifically examined the concentrations of Sr, Zn, Mn, Cu, As, Cd, Cr, Co, Sb, Pb, Tl, Ni, and Hg, detailing their spatial distribution and associated risks. Sources of pollution were identified, and their relationships were explored using statistical analysis and positive matrix factorization (PMF). The risk assessment results indicated elevated pollution levels of Tl and slight pollution of Hg in surface water. Integrated Nemerow Pollution Index (P
N ) calculations revealed that 18% and 20% of surface water samples exhibited pollution during the wet and dry seasons, respectively. In sediments, mean concentrations of Mn, As, Ni, Cr, Zn, Cu, Cd, Sr, Co, Sb, and Tl exceeded background levels, with Mn being the highest. Sediments exhibited low to moderate HM pollution, with higher concentrations found in northern Ningxia's irrigated areas. Major sources of HM pollution included agriculture, traffic emissions, and natural sources. Overall, this study provides essential data to improve water resource management and mitigate HM pollution in the Ningxia section of the Yellow River Basin. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Ecologically sustainable urban design plays a pivotal role in mitigating climate change. This study develops an indicator group consisting of urban ecological emergy, land use change, population density, ecological services, habitat quality, enhanced vegetation index, carbon emissions, and carbon storage to assess urban sustainability. By leveraging a dataset from 2000 to 2020, we employ a neural network to predict emergy sustainability indicators over a time series, projecting the sustainable status of Xuzhou City from 2020 to 2050. The findings indicate that urbanization has led to significant changes in land use, population distribution, ecological service patterns, habitat quality degradation, vegetation fragmentation, and fluctuating carbon dynamics. Cropland constitutes the predominant land type (90.6%), followed by built-up land (8.49%). The neural network predictions suggest that Xuzhou City's sustainable status is subject to volatility (15–20%), with stability expected only as the city matures into a developed urban area. This research introduces a novel approach to urban sustainability analysis and provides insights for policy development aimed at fostering sustainable urban growth. [ABSTRACT FROM AUTHOR]

This article addresses a significant aspect of evaluating and comparing spatial forest data from various databases developed and maintained in Poland and globally. The study focused on the application of these data to create terrain passability maps, which are useful in planning military and crisis operations. The research was conducted in a test area near Warsaw, encompassing the Kampinos Forest. In the study, the "forest" layers from the tested databases were compared. Their spatial extents were analyzed, and terrain passability maps were generated in different configurations, which were comprehensively compared with one another. The results indicated that the quality and detail of forest data are not critical for generating passability maps. Only in the case of creating highly detailed maps does the use of precise data prove justified. As the level of detail in the maps decreases, they become increasingly similar, reducing the influence of the forest data on their accuracy and operational applicability. The study enabled the selection of the most accurate data sources on forested areas—those that most faithfully represent the structure of forested regions in Poland. [ABSTRACT FROM AUTHOR]

This study aims to explore the spatial distribution and site selection characteristics of cultural heritage sites, as well as the impact of the natural environment on the site's location. A total of 448 cultural heritage sites in Jinan City (Shandong province), which have been listed as key cultural relic protection units from before the Qin Dynasty to after the Qing Dynasty (ca. 7500 BCE–present), were analyzed using spatial analysis tools in ArcGIS 10.6 software. The main research findings are as follows: (1) cultural heritage sites have a wide distribution and few cores and are characterized by spatial agglomeration and the formation of a single core area around the Lixia District; (2) in terms of spatiotemporal evolution, cultural heritage sites follow a "diffusion–aggregation–diffusion–aggregation" trend, exhibiting a "southwest–northeast–northwest" trajectory, with characteristics of continuity and a centripetal pattern; and (3) cultural heritage sites are mainly distributed in alluvial plains with heights ranging from 2.6–100 m, slopes ranging from 0–5°, and distances ≤ 1 km from water systems. The more recent the construction year of the cultural heritage site is to modern times, the more closely its type is to production and living, and the more relevant it is to the natural environment.

Simple Summary: This study focuses on 25 species of flea beetles from the genus Calotheca, which are found in South Africa. Using ecological data like temperature, rainfall, and vegetation types, the research aims to understand what environmental factors influence where these beetles live. By using ecological niche modelling, this study identifies patterns for each species and for the entire genus. The results show that certain climate factors, such as the average temperature during the wettest and driest seasons, and rainfall in the wettest period, play an important role in the beetles' distribution. Also, it highlights that areas most suitable for these beetles overlap with regions where their host plants, from the Searsia genus, are common. Our findings help us better understand the relationship between Calotheca species and their environment, with important implications in a biogeographic context. In this work, the 25 species of the flea beetle genus Calotheca Heyden recorded for South Africa are considered. Starting from the updated species distribution and the topographic, temperature, and precipitation variables, as well as the vegetation types in the occurrence sites, through an analysis of ecological niche modelling, a possible ecological profile is provided, both for each species and the entire genus, highlighting some of the factors that drive their occurrence and distribution patterns. Along with the vegetation type, some climatic variables were found to be particularly influential, such as the mean temperature of both the wettest and driest quarters and also the mean precipitation of the wettest period. Finally, comparing the distribution of the areas of highest suitability returned by the model obtained for Calotheca, they largely overlap with the highest-density areas of Searsia, genus of Anacardiaceae, including the main host plants for these flea beetles.

From the geomorphological point of view, urbanization changes fluvial systems more drastically than any other single human activity. Its impact on rivers is of interest as it results in serious issues concerning geomorphic instability, ecosystem service reduction, and geo-hydrological risk increase. The present study provides a quantitative and qualitative assessment of landscape changes driven by urbanization, which occurred from the mid-19th century to the present day along the lower reaches of the Bisagno and Polcevera rivers and their tributaries in the Mediterranean coastal city of Genova (NW Italy). The bankfull channel morphological adjustments, the minor hydrographic network disappearance, the land use and land cover changes, and the current physical accessibility of river margins were investigated. This work is based on collection and review of historical data, photograph interpretation, GIS analysis, and field surveys. Urbanization essentially occurred between the mid-19th century and the late 1930s. The bankfull channel of the Bisagno and Polcevera rivers experienced large narrowing associated with widespread establishment of channelization structures. The minor hydrographic network essentially disappeared underground. After the 1930s, further minor anthropogenic interventions were implemented to accommodate urban expansion and consolidate channelization works; however, the overall geomorphological setting remained unchanged. The geomorphological evolution of the Bisagno and Polcevera rivers followed three different phases associated with the urban expansion process. Nowadays, the study area is completely urbanized, the fluvial stems flowing through the valley floor are totally disconnected from their adjacent areas, the main rivers show a relevant geomorphological stability induced by anthropogenic pressures, and the accessibility of river margins for people is rather limited. The outcomes from this study represent an essential knowledge base for technicians and policymakers to plan urban development and inform effective and sustainable management measures. Moreover, they provide insights into the medium- and short-term morphological evolution of urban rivers. [ABSTRACT FROM AUTHOR]

The rehabilitation of mine waste dumps is a critical environmental challenge, particularly in areas like Uricani, Romania, where such sites are often characterized by hazardous conditions and poor ecological recovery. This study addresses the need for efficient, low-cost solutions for land reclamation by employing UAV photogrammetry and GIS spatial analysis to assess the potential for afforestation with Robinia pseudoacacia L., a species known for its soil stabilization and ecological benefits. Using UAV technology, high- resolution digital terrain models and orthophotos were generated, with an RMSE of 0.086 m, demonstrating the accuracy and efficiency of this method for large-scale landscape initiatives. GIS spatial analysis was performed to create six key terrain maps and four pedoclimatic factor maps, essential for evaluating the site's suitability for ecological restoration. The pilot afforestation project, which involved planting R. pseudoacacia, achieved a 75% survival rate after four years, suggesting that the species can thrive under the site's conditions. The landscape design proposal incorporates recreational spaces aimed at benefiting the local community and attracting tourism, thereby contributing to the area's economic and cultural revitalization. The interdisciplinary integration of UAV surveying, GIS, and landscape design highlights the cost-effectiveness and interdisciplinary nature of this approach, offering a sustainable model for mine waste dump reclamation and future ecological restoration projects.

Understanding the mechanisms whereby parks contribute to cooling urban settings is critical to effectively addressing the challenges posed by rising temperatures in densely populated cities and ultimately improving the quality of urban life. This study employs a spatial approach with advanced analytical techniques, including local entropy mapping, to quantify surface temperature changes induced by urban parks across different geographical areas. Using satellite imagery to estimate land surface temperature (LST) during a heat wave in Mexico City, the study provides a practical approach to understanding the complex relationship between urban park size and urban heat island intensity within 300 m. The study's findings indicate that while parks exert a cooling influence on their immediate vicinity, the extent of this effect varies spatially and depends on factors such as the size and location of the park and the nature of the surrounding terrain. Specifically, the results indicate that this relationship is not randomly distributed across the urban landscape. Instead, there is a clear pattern of spatial clustering within the city. Consequently, this research underlines the complexity of the problem, emphasizing the indispensable role of urban design and planning strategies to harness the full potential of parks as cooling agents within cities.

Introduction: Crop Wild Relatives (CWR) have great socioeconomic importance for humans harbouring a broad spectrum of diversity and being important elements of different habitats. Beta vulgaris subsp. maritima ((L.) Arcangeli), also known as sea beet, is an important CWR of cultivated beets (GP-1). The high adaptability of this taxon to different environmental conditions, as well as its tolerance/resistance to different biotic and abiotic stresses, makes it a vital source for sugar beet improvement. Aim of this work was to analyse the in situ and ex situ status of sea beet population conservation in Italy, so as to guide protection activities and new collecting missions. Methods: Geographical distribution data of populations were that occur in the wild and conserved in genebanks were assembled from different databases and submitted to data quality control. Distribution, habitat characterization, land cover and use of the involved sites were then evaluated to provide insight into the current condition of areas hosting this CWR diversity. The presence of populations within vs. outside Italian protected areas was also evaluated. A density analysis of the records was performed and the adequateness of sea beet ex situ conservation, in terms of number of conserved accessions, was finally estimated. Results: A collection of 138 B. vulgaris subsp. maritima high quality georeferenced records were obtained, mainly distributed into Mediterranean Biogeographic Region. About 22% of the considered populations occurs in protected sites of the Natura 2000 Network, while about 15% in areas recorded in the Official list of protected natural areas (EUAP). Occurrences within protected areas are founded primarily in natural environments, whereas those outside are mainly located in urban and cultivated areas. The comparison of distribution and density analysis results revealed the presence of several gaps between sites hosting in situ populations and sites where ex situ conserved accessions were originally collected. Discussion: Here presented data indicates that the protection status for sea beet in Italy can be considered only partially adequate; more proactive protection measures should be foreseen to increase the role of protected areas in safeguarding in situ conservation. "Out of reserve management" for populations outside protected areas should also be developed, as well as new collecting missions carried out. [ABSTRACT FROM AUTHOR]

The impacts on living conditions and natural habitats deriving from planning decisions require complex analysis of cross-acting factors, which in turn require interdisciplinary data. At the municipal level, both data collection and the knowledge needed to interpret it are often lacking. Additionally, climate change and species extinction demand rapid and effective policies in order to preserve soil resources for future generations. Ex-ante evaluation of planning measures is insufficient owing to a lack of data and linear models capable of simulating the impacts of complex systemic relationships. Integrating machine learning (ML) into systemic planning increases awareness of impacts by providing decision-makers with predictive analysis and risk mitigation tools. ML can predict future scenarios beyond rigid linear models, identifying patterns, trends, and correlations within complex systems and depicting hidden relationships. This article focuses on a case study of single-family houses in Upper Austria, chosen for its transferability to other regions. It critically reflects on an ML approach, linking data on past and current planning regulations and decisions to the physical environment. We create an inventory of categories of areas with different features to inform nature-based solutions and backcasting planning decisions and build a training dataset for ML models. Our model predicts the effects of planning decisions on soil sealing. We discuss how ML can support local planning by providing area assessments in soil sealing within the case study. The article presents a working approach to planning and demonstrates that more data is needed to achieve well-founded planning statements.

Abruzzo Periadriatic Area (Central Italy) is sadly acknowledged as highly exposed to geo-hydrological hazards, with small-to-medium size catchments and urban areas strongly affected by natural phenomena. In the present work, the Pescara River basin, hit in the past by several floods and concurrent superficial landslides due to localized and intense rain events, has been studied. A screening of morphometry, land use changes, rainfall datasets, and flooding-related effects on landscape has been carried out, both at the catchment and local scales. A morphometric and geomorphological approach was applied, supported by GIS software and implemented with literature data. It allowed us to derive insights about the interaction between land use changes and geo-hydrological phenomena. Over the past 60 years, the study area underwent increases in built-up areas from ~16 km2 in 1955 to ~67 km2 in 2019 with significant sprawl at low altitude. Rainfall datasets outlined moderate-to-low annual precipitation with occasional heavy rainfall events (>100 mm/d and 30–40 mm/h). Historical and recent events (~35 events over a 100-year period) linked to landscape and geomorphological processes were also counted. Resulting data allowed to implement knowledge about the present-day geomorphological arrangement of the basin, providing information for land management in a changing environment. These findings provide valuable insights for future urban planning, policy formulation, and sustainable development initiatives, readily available to interested stakeholders.

This study combines the traditional method of geological and geomorphological mapping with a quantitative GIS analysis to examine landforms and debris flows channels. Using a high-resolution DEM (5 m) as a base, the geomorphological map highlights the various landforms around the Alpe di Succiso (Northern Apennines, Italy), including glacial and cryoclastic features, slope landforms and deposits due to gravity (particularly debris flow) and deposits due to running waters. The methodology applied to the channels is based on the geomorphometric parameters derived from the DEM, including Topographic Wetness Index (TWI), Terrain Ruggedness Index (TRI), Slope Angle, and Elevation extracted every 10 m along each channel and grouping the channels in four classes based on their lengths. Within each class, multiple ranking criteria were employed for the identification of channels showing anomalous or common patterns. Debris flow channels exhibit anomalous patterns in the geomorphometric parameters, indicating significant variations in their topographical characteristics..

Abstract China’s northern Fujian, as one of the spatial carriers of renowned traditional Chinese cultures such as Minyue, Zhu Xi’s Neo-Confucianism, tea, and porcelain, has preserved a wealth of tangible cultural relics, showcasing a profound cultural heritage and possessing strong research value and development potential. This study employs GIS spatial statistical analysis and map visualization technology to unveil the evolutionary processes of cultural heritage sites in northern Fujian, focusing on their spatial types, forms, and densities across different historical periods. Based on this foundation, the research further delves into the intrinsic relationships between the spatial distribution characteristics of cultural heritage sites in northern Fujian during various historical periods and the local natural and cultural environment. The results indicate that: (1) the spatial distribution of cultural heritage sites in northern Fujian varies across different historical periods, with the highest concentration and quantity observed during the Ming and Qing periods. In contrast, the Qin, Han, Wei, Jin, Northern and Southern Dynasties period exhibits the lowest quantity and a more dispersed distribution. (2) Cultural heritage sites in northern Fujian are mainly distributed in the relatively flat terrain below 400 m above sea level, including middle to low-altitude mountain basins, river valleys, and low hills. In terms of distance from rivers, cultural heritage sites exhibit a clear distribution pattern along rivers, with a large number of them located within 0–6 km from the riverbanks. (3) The spatial distribution of cultural heritage sites in northern Fujian is influenced not only by macro-environmental factors such as topography, altitude, and rivers but also by micro-shaping from social and cultural elements like Minyue culture, tea and porcelain ancient road culture, Zhu Xi’s Neo-Confucianism culture, religious beliefs and customs culture, and red revolutionary culture across different historical periods. This study contributes to the establishment of a model correlating cultural heritage sites with historical periods and provides an interdisciplinary methodological framework to understand the relationship between cultural heritage sites and the geographical environment.

As urbanization continues to increase, changes in the ecological characteristics of urban areas are becoming more reasonable to meet the needs of a growing population. However, the profound impact of human-induced urban pressures on land, often called the "billing impact", is strongly emphasized in research publications. In many cases, contemporary anthropogenic processes alter the dynamics of environmental functions in complex ways. Urban regions meet a particular climate regime characterized by increased air temperatures compared to peripheral areas and a significant reduction in wind speed, attributable to the interaction of natural and anthropogenic factors. An urban heat island (UHI) occurs when the air above populated areas heats up additionally, causing air to flow from the site's edges to its center and creating a heat dome. This study reveals the influence of urbanization on microclimatic changes, encompassing increased evapotranspiration, altered vegetation cover, and temperature fluctuations. The results illustrate environmental transformations caused by abrupt and unregulated urbanization in the mountainous area of Zlatibor, Serbia, a trend that has intensified over the past decade.

- Abstract
Facility connectivity plays a pioneering role in the Belt and Road Initiative proposed by General Secretary Xi Jinping in 2013. Xinjiang, as the core area of the Silk Road Economic Belt bordering eight Eurasian countries, plays a crucial role in cross-border transportation and humanistic exchanges and is the focus of the national connectivity initiative. While the current analysis on regional accessibility has become more diversified, analyses on long-distance cross-border corridors are still relatively rare. Therefore, this paper takes the Xinjiang Uygur Autonomous Region (XUAR) of China as the main study area extending westward to the five Central Asian countries. Modified accessibility accounting methods and gravity models are used to analyze the current status of accessibility and the strength of economic ties between Xinjiang and the five Central Asian countries. The results showed that the distance decay effect of transportation accessibility between Xinjiang and the five Central Asian countries is obvious; the constraints of "natural geography + transportation economy" affect the accessibility level from each state in Xinjiang to the five Central Asian countries and shows a trend of strength in the north and weakness in the south. From the optimization of the regional planning road network in a reverse projection, G3033 and other highways and the construction of the Yi-A railroad will improve the status quo of "east-west access but not north-south access" in Xinjiang. The "corridor effect" and spatial polarization characteristics of economic connection intensity from Xinjiang to the five Central Asian countries are significant. This study has important theoretical and practical significance for the construction of cross-border corridors. [ABSTRACT FROM AUTHOR]

Infilling is considered one of the most important planning principles worldwide to reduce urban growth and urban sprawl. This also applies to Germany. However, due to a lack of nationwide small-scale data, there are hardly any empirical findings on how infilling has taken place in German cities. Using a newly developed GIS-based algorithm and small-scale data on residential construction activity (100x100m grid cells) and built-up areas, we analyse how residential development has evolved in 30 German case studies over a study period from 1991 to 2011. Within concentric 1km rings, our analysis differentiates residential construction activity by infilling, building types, land cover and housing density. Using cluster analysis, we further group the case studies into more homogeneous groups. The findings show that infilling has been pursued and implemented by most of the case studies since the 1990s. However, it becomes clear that there are large differences in the extent of infilling and that it does not necessarily lead to an increase in housing density. The findings show - in addition to national regulations and guidelines as well as population development - that it is primarily the structural framework conditions, the specific commitment of the municipalities as well as local and regional challenges that determine the type of residential construction activity.

- Abstract
The aim of this research is to address the challenge of transforming car-oriented industrial parks into pedestrian- and bicycle-friendly environments. Through the implementation of a multi-criteria decision-making (MCDM) approach, the study aims to evaluate alternative pathway connections and assess their potential impact on bicycle and pedestrian traffic volumes. By enhancing the connectivity of the cycling pathway network, the research seeks to demonstrate the potential for substantial increases in cycling and walking within industrial zones. This research leverages a multi-criteria decision-making framework, specifically the ARAS-G method, and integrates geographic information system analysis alongside Python scripting to project future bicycle usage and assess alternative pathway connections. The study underscores the potential for substantial increases in cycling and walking by augmenting the connectivity of the cycling pathway network. The findings hold practical significance for urban planners and industrial zone developers, advocating a holistic approach to sustainable transportation. The research contributes a comprehensive set of criteria encompassing connectivity, safety, accessibility, efficiency, integration within the urban fabric, and cost-effectiveness to evaluate sustainability and prioritize actions and measures for reestablishing industrial zones as bicycle-friendly spaces.

Urbanization has profoundly reshaped the patterns and forms of modern urban landscapes. Understanding how urban transportation and mobility are affected by spatial planning is vital. Urban vibrancy, as a crucial metric for monitoring urban development, contributes to data-driven planning and sustainable growth. However, empirical studies on the relationship between urban vibrancy and the built environment in European cities remain limited, lacking consensus on the contribution of the built environment. This study employs Munich as a case study, utilizing night-time light, housing prices, social media, points of interest (POIs), and NDVI data to measure various aspects of urban vibrancy while constructing a comprehensive assessment framework. Firstly, the spatial distribution patterns and spatial correlation of various types of urban vibrancy are revealed. Concurrently, based on the 5Ds built environment indicator system, the multi-dimensional influence on urban vibrancy is investigated. Subsequently, the Geodetector model explores the heterogeneity between built environment indicators and comprehensive vibrancy along with its economic, social, cultural, and environmental dimensions, elucidating their influence mechanism. The results show the following: (1) The comprehensive vibrancy in Munich exhibits a pronounced uneven distribution, with a higher vibrancy in central and western areas and lower vibrancy in northern and western areas. High-vibrancy areas are concentrated along major roads and metro lines located in commercial and educational centers. (2) Among multiple models, the geographically weighted regression (GWR) model demonstrates the highest explanatory efficacy on the relationship between the built environment and vibrancy. (3) Economic, social, and comprehensive vibrancy are significantly influenced by the built environment, with substantial positive effects from the POI density, building density, and road intersection density, while mixed land use shows little impact. (4) Interactions among built environment factors significantly impact comprehensive vibrancy, with synergistic interactions among the population density, building density, and POI density generating positive effects. These findings provide valuable insights for optimizing the resource allocation and functional layout in Munich, emphasizing the complex spatiotemporal relationship between the built environment and urban vibrancy while offering crucial guidance for planning.

IntroductionCrop Wild Relatives (CWR) have great socioeconomic importance for humans harbouring a broad spectrum of diversity and being important elements of different habitats. Beta vulgaris subsp. maritima ((L.) Arcangeli), also known as sea beet, is an important CWR of cultivated beets (GP-1). The high adaptability of this taxon to different environmental conditions, as well as its tolerance/resistance to different biotic and abiotic stresses, makes it a vital source for sugar beet improvement. Aim of this work was to analyse the in situ and ex situ status of sea beet population conservation in Italy, so as to guide protection activities and new collecting missions.MethodsGeographical distribution data of populations were that occur in the wild and conserved in genebanks were assembled from different databases and submitted to data quality control. Distribution, habitat characterization, land cover and use of the involved sites were then evaluated to provide insight into the current condition of areas hosting this CWR diversity. The presence of populations within vs. outside Italian protected areas was also evaluated. A density analysis of the records was performed and the adequateness of sea beet ex situ conservation, in terms of number of conserved accessions, was finally estimated.ResultsA collection of 138 B. vulgaris subsp. maritima high quality georeferenced records were obtained, mainly distributed into Mediterranean Biogeographic Region. About 22% of the considered populations occurs in protected sites of the Natura 2000 Network, while about 15% in areas recorded in the Official list of protected natural areas (EUAP). Occurrences within protected areas are founded primarily in natural environments, whereas those outside are mainly located in urban and cultivated areas. The comparison of distribution and density analysis results revealed the presence of several gaps between sites hosting in situ populations and sites where ex situ conserved accessions were originally collected.DiscussionHere presented data indicates that the protection status for sea beet in Italy can be considered only partially adequate; more proactive protection measures should be foreseen to increase the role of protected areas in safeguarding in situ conservation. “Out of reserve management” for populations outside protected areas should also be developed, as well as new collecting missions carried out.

The present study falls within the scope of the analysis of the morphodynamic potential of the Bran - Dragoslavele Corridor (Romania), a low mountain area, favorable to erosion processes due to the high energy of the relief, diversified lithology, tectonic complexity, and due to the variation in the energy of atmospheric risk phenomena. For the expansion of pastoral agricultural areas and those intended for human settlements, the deforestation of the last 3-4 centuries deprived the slopes and the soil of the protective forest cover on an area of 55.44%, favoring the amplification of the action of natural morphodynamic agents. In this context, the quantitative and spatial assessment of sheet erosion, expressed as the average annual rate of surface soil erosion (measured in tons hectare–1) was approached by applying the calculation model implemented in the GIS environment by using the universal soil loss equation (USLE). Implementation of the model was realized through the spatial delimitation of the potential erosion and the rendering by susceptibility classes of the quantitative results which reveal the fact that the largest surface of the studied mountain unit (91.68%) presents tolerable values, of 0-1.5 t ha–1 year–1. The highest values, over 4 t ha–1 year–1 (1.24%), are characteristic of the calcareous areas belonging to the many sectors of the gorges with discontinuous vegetation, as well as the limestone exploitation area from Mateiaș mountain. The quantitative knowledge and spatial distribution of surface erosion becomes important for communities and local authorities, interested in the planning and management of the implementation of some agrotechnical measures to improve the quality and productivity of soils or to prevent and restrict erosion processes with a tendency to expand areally and in depth.

The study presents the first comprehensive spatio-temporal analysis of eutrophication and the consequent loss of sensitive aquatic habitats in the transitional water bodies along the Kamchiya-Shkorpilovtsi sector of the Bulgarian Black Sea coast. The research focuses on the Maznia Azmak Lake, an old Kamchiya riverbed integral to the Kamchia Nature Reserve and two Natura 2000 protected areas. The primary objective was to assess the scale and rate of eutrophication and its impact on aquatic habitats, employing modern methodologies such as drone surveys, high-precision GPS geodetic measurements, and bathymetric investigations. Data was gathered from 2019 to 2023, including key physicochemical parameters (pH, dissolved oxygen, conductivity, temperature, chemical oxygen demand (COD), biological oxygen demand (BOD), total nitrogen, and phosphorus). Results indicate that Maznia Azmak Lake exhibited stable pH levels (7.8-8.3) and increasing conductivity (up to 964 pS/cm), with dissolved oxygen levels varying significantly (4.8-9.3 mg/l). The lake's COD and BOD values suggested moderate organic pollution, with nutrient levels remaining low. Seasonal salinity variations were observed, correlating with low summer water levels and sea wave activity. The macrophyte analysis revealed a heterogeneous mix of species with minimal helophyte dominance. Popovo Blato Lake demonstrated low dissolved oxygen levels and high conductivity (peaking at 992 µS/cm), with COD reaching 40.6 ml O2/l in September 2023, indicating severe organic pollution. Conversely, Petrovo Blato Lake had variable dissolved oxygen and high conductivity, with low nutrient levels, though occasional COD and BOD peaks suggested episodic pollution events. The mouth of the Fandakliyska River, showing stable pH and conductivity, had relatively higher dissolved oxygen levels, pointing to better overall water quality compared to the lakes. This area's episodic pollution events were reflected in variable COD and BOD values. The results underscore the critical need for ongoing monitoring and targeted interventions to mitigate pollution and preserve these vulnerable aquatic habitats. This pioneering study contributes valuable baseline data and insights into the eutrophication processes affecting the Bulgarian Black Sea coast, emphasizing the importance of preserving these ecosystems for their biodiversity and ecological services.

Global climate change and rapid urbanization have increased the frequency of flooding, making urban flood resilience a critical objective. This article introduces a methodology for assessing urban flood resilience, utilizing a social-ecological synthesis index that integrates geographical and temporal data with Geographic Information System (GIS). The study focuses on ten administrative subdistricts in Wuhua District, Kunming City, China, and selects 18 social-ecological indicators. These indicators, chosen from social and ecological perspectives, are weighted using the entropy weight method to determine their significance in the assessment system. By combining scores for each subdistrict, the study quantifies flood resilience and creates a spatial distribution map using ArcGIS. Key findings reveal that out of the ten administrative subdistricts, five in Wuhua District, particularly in the core urban area of Kunming, demonstrate strong overall flood resilience. Influenced by social-ecological indicators, there is significant spatial differentiation in flood resilience within Wuhua District, with a decreasing trend radiating from the city center to areas farther from the urban core. The research indicates that regions with well-established transportation infrastructure, a wide distribution of government institutions, improved water management facilities, and a substantial population with higher education levels contribute significantly to enhancing urban flood resilience.

Toplica district represents an area in Southern Serbia with significant forms of geoheritage that have not been valorized yet. The aim of this pioneering study is to systematically analyze and evaluate all manifestations of the geodiversity in the Toplica district. Based on the geological importance, degree of attractiveness, and size, a total of six geosites were selected. The main goal of the study is to emphasize the insufficient utilization of huge geotourism potentials of the Toplica district and to determine the current geotourism development and geotourism potential of evaluated geosites. The geotourism suitability of each geosite is defined through comparative analysis. The Geosite Assessment Model (GAM) is used to assess the current state of the various elements of geodiversity in the study area. Positioning within the GAM matrix is defined by the values of the investigated parameters. Visualization of the distribution of the GAM indicators is an innovative approach for the interpretation of the obtained results. As a projection of the geotourism potential, the study presents the results of the traffic accessibility of geosites using the Geographic Information System (GIS)-based isochronous method. GIS and Digital Terrain Models are used in the visualization of the research area. The results of GAM apostrophize the current tourist value of Devil’s City, while the isochron analysis of GIS highlights the great geotourism potential of publicly little-known and touristically unaffirmed geosites. The results represent a basis that can support the affirmation of geotourism, the improvement of existing, and the development of new geotourism strategies in the Toplica district.

Understanding the mechanisms whereby parks contribute to cooling urban settings is critical to effectively addressing the challenges posed by rising temperatures in densely populated cities and ultimately improving the quality of urban life. This study employs a spatial approach with advanced analytical techniques, including local entropy mapping, to quantify surface temperature changes induced by urban parks across different geographical areas. Using satellite imagery to estimate land surface temperature (LST) during a heat wave in Mexico City, the study provides a practical approach to understanding the complex relationship between urban park size and urban heat island intensity within 300 m. The study’s findings indicate that while parks exert a cooling influence on their immediate vicinity, the extent of this effect varies spatially and depends on factors such as the size and location of the park and the nature of the surrounding terrain. Specifically, the results indicate that this relationship is not randomly distributed across the urban landscape. Instead, there is a clear pattern of spatial clustering within the city. Consequently, this research underlines the complexity of the problem, emphasizing the indispensable role of urban design and planning strategies to harness the full potential of parks as cooling agents within cities.

Abstract In coastal alluvial plains, the variability of sedimentary inputs, tectonic and eustatism causes a complex subsurface geology which influences the position of fresh/saltwater interface. Furthermore, in these areas densely populated, the over-pumping of freshwater, coupled with the climate change events, promotes the landward migration of freshwater/saltwater boundary. This research illustrates the ability of geophysical tools to recognize the presence of salt/brackish water at Volturno Coastal Plain, Southern Italy. This area is characterized by a peculiar geological setting, due to the proximity at Somma–Vesuvio and Campi Flegrei volcanic areas, which profoundly influences the circulation of groundwater. The subsurface is mainly characterized by: (i) two denser layers located at − 10 m and − 20 m depth which in part prevents the vertical migration of groundwater, (ii) facies heteropy that facilitates the hydraulic connection between the different geological bodies, (iii) a discontinuous Campanian Ignimbrite deposits which favor the hydraulic connection between deeper and shallower aquifers. In this geological framework, 2D-ERT and 3D-ERT integrated with Downhole, Multichannel Analysis of Surface Waves and boreholes made possible to recognize the presence of two main zones with salt and brackish waters, respectively. The first zone, characterized by very low resistivity (≤ 1 Ωm) typical of salt water, stretches 1.5 km inland from the coast. The second zone, with a resistivity between 2 and 5 Ωm typical of brackish water, continues for other 3 km inland. This knowledge is useful for the engagement of all stakeholders (farmers, ranchers and policy makers) in the sustainable use of fresh water and for making water management plan operational tools.

The study of the evolution of regional typology of archaeological cultures is essential in understanding the trajectory of cultural evolution from a temporal and spatial perspective. In this paper, we focused on the Taihu Lake region, one of the six major regional typologies of Neolithic archaeological cultures in China. By utilizing archaeological site data from the Neolithic Era in this region, our study investigates the evolution of typologies in archaeological cultures at both regional and sub-regional scales. From a broad perspective, quantitative methods were used to explore the cultural evolution process in the Taihu Lake region. The degree of social integration and intercultural inheritance can be reflected through the size of the site and the superimposition of cultural layers. In addition, climate and environmental data were combined to investigate its driving factors. Moreover, GIS (Geographic Information System) analysis methods were used to cluster and partition the cultures in the Taihu Lake region. By identifying distinct groups of sites, it is possible to deconstruct and analyze the interior of the cultures to study their distribution patterns and to explore the exchanges and expansions within the cultures. By integrating both research approaches, our study provides a comprehensive analysis of the evolutionary characteristics of the regional typology of archaeological cultures within the Taihu Lake region. These findings contribute to the development of quantitative methods for studying the evolutionary trajectory of archaeological cultural systems. [ABSTRACT FROM AUTHOR]

- Abstract
Outdoor running has a positive impact on human health. Our study attempted to address the issue of what other aspects motivate people to take up running. We were particularly interested in the landscape and its significance at the stage of decision making regarding participation in races. Our goal was also to identify the landscape features of routes, which determine their popularity. We conducted surveys among running participants and spatial analyses using GIS tools. Great landscape values of running routes can contribute to the activation of a running society, especially those including women and city dwellers. The high diversity of the landscape of cross-country routes, especially in terms of their relief and land use, significantly affects their high landscape rating. Route profiles and running challenges are as important as landscape values. The landscape that runners observe during long-distance runs affects their regeneration and motivates them to finish competitions. Runs organised in mountain and foothill landscapes, characterised by a wide variety of landscapes, are particularly attractive for runners. This study illuminates how the enchanting tapestry of landscapes not only fuels the passion for outdoor running but also underscores the intricate relationship between humans and their surroundings. The results enable us to establish the key principles for designing new running routes that support runners during their exertion. [ABSTRACT FROM AUTHOR]

Rashid, Muhammad Ahsan, Leonelli, Giovanni, and Chelli, Alessandro
- Abstract
This study combines the traditional method of geological and geomorphological mapping with a quantitative GIS analysis to examine landforms and debris flows channels. Using a high-resolution DEM (5 m) as a base, the geomorphological map highlights the various landforms around the Alpe di Succiso (Northern Apennines, Italy), including glacial and cryoclastic features, slope landforms and deposits due to gravity (particularly debris flow) and deposits due to running waters. The methodology applied to the channels is based on the geomorphometric parameters derived from the DEM, including Topographic Wetness Index (TWI), Terrain Ruggedness Index (TRI), Slope Angle, and Elevation extracted every 10 m along each channel and grouping the channels in four classes based on their lengths. Within each class, multiple ranking criteria were employed for the identification of channels showing anomalous or common patterns. Debris flow channels exhibit anomalous patterns in the geomorphometric parameters, indicating significant variations in their topographical characteristics.. [ABSTRACT FROM AUTHOR]

SYNTHETIC aperture radar , *RADAR interferometry , *HUMAN settlements , *CONCEPT mapping , *REMOTE sensing , *RAPID tooling - Abstract
Deep-seated gravitational slope deformations (DsGSDs) are slope-scale phenomena which are widespread in mountainous regions. Despite interacting with human infrastructures and settlements, only a few cases are monitored with ground-based systems. Remote sensing technologies have recently become a consolidated instrument for monitoring and studying such widespread and slow processes. This paper proposes a three-step novel methodology to analyze the morpho-structural domain of DsGSDs by exploiting the advanced Differential Synthetic Aperture Radar Interferometry (A-DInSAR) technique through (i) the analysis of A-DInSAR measurement point density and distribution defining a coverage threshold; (ii) the assessment of the actual ground deformation with respect to the orientation of phenomena based on slope, aspect, and C-index; and (iii) ground deformation mapping with previously ranked velocity interpolation. The methodology was tested on two differently oriented phenomena: the mainly north–south-oriented Croix de Fana and the mainly east–west-oriented Valtournenche DsGSD, located in the Aosta Valley Region, northern Italy. The results show a variation in the kinematic behavior between the morpho-structural domains, while also considering any other superimposed surficial deformations. This work provides the lines for the implementation of a rapid and low-cost tool based on the use of A-DInSAR measurements which are suitable for assessing the impact of any type of DsGSD on the anthropic facilities and infrastructures in mountainous areas.

Antonov, S. A. and Peregudov, S. V.
- Abstract
The research was performed to develop a scientific and methodological approach to the analysis of the dynamics of water erosion based on GIS technologies and Earth remote sensing data, using the fractal dimension index. This approach was tested by the example of a local area (Budennovskii test plot) of ploughed slope lands located in Budennovsk district of Stavropol krai. The research was based on modern geoinformation technologies and Earth remote sensing data for 2007, 2008, 2010, and 2022, which were used to create a retrospective digital relief model of the study area. Freely available images from the ALOS PULSAR and Sentinel-1 satellites, were taken as data sources, which significantly expanded the range of their application. The topography of the area of the Budennovskii test plot is dominated by southern slopes (28%), the mean slope steepness is 2.3°, and watercourses of six orders are typical. The value of the fractal dimension index (geometric complexity of the figure) increases from 0.79 in 2007 to 0.86 in 2022, which indicates the enhancement of water erosion processes. Identification of areas with a rise in this index will allow us to effectively plan measurers for erosion control, paying most attention to areas with significant increases. The proposed scientific and methodological approach may be applied in any agrarian region of Russia taking into account soil-climatic and morphometric features. It enables quick and reliable assessment of the degradation processes over vast areas. [ABSTRACT FROM AUTHOR]

The first zone, characterized by very low resistivity (≤ 1 Ωm) typical of salt water, stretches 1.5 km inland from the coast. The second zone, with a resistivity between 2 and 5 Ωm typical of brackish water, continues for other 3 km inland. This knowledge is useful for the engagement of all stakeholders (farmers, ranchers and policy makers) in the sustainable use of fresh water and for making water management plan operational tools.

Abstract Grottoes are a comprehensive art treasure trove that integrate architecture, sculpture, and murals. They showcase the historical spiritual civilization of humanity and provide a solid foundation for studying the dissemination and development of Buddhist culture. Gansu Province is an important node on the transmission route of Buddhist culture, constituting a relatively complete and rich history of Buddhist art and cultural history. This article uses GIS technology to systematically analyse the spatial distribution characteristics and spatiotemporal evolution patterns of grottoes in Gansu Province from the Wei Jin to the Ming and Qing dynasties and explores the main factors affecting their distribution. The results indicate the following: (1) the grottoes in Gansu Province exhibit clustering and uneven distribution characteristics, which form the core aggregation area of Qingyang Tianshui City and the secondary aggregation area of Wuwei and Zhangye City. (2) Spatiotemporal characteristics show significant changes in the number and focus of excavation and repair of grottoes in Gansu Province over the years. The Northern and Southern Dynasties, Sui and Tang Dynasties, and Ming and Qing Dynasties had more grottoes than the Wei, Jin, and Yuan Dynasties. The overall centre of gravity shifted from northwest to southeast. Natural factors such as topography, stratigraphy, and hydrology and cultural factors such as politics and transportation significantly impacted the spatial pattern of grotto heritage in Gansu Province. Exploring and studying the spatial layout of grotto heritage from the perspective of historical geography is beneficial for understanding the cultural development and historical changes in Buddhism and is of great significance for the development of landscape environmental protection and utilization of grotto heritage.

In the industrial corridor of Boyacá, Colombia, population growth is accompanied by anthropogenic activities such as industrial operations, vehicle exhaust fumes, mining, smelting, atmospheric deposition, and excessive use of chemical products to promote crop growth. These activities are known to have a significant impact on urban and rural soils, contributing significantly to elevated concentrations of potentially hazardous elements in the environment. This industrial corridor is an area of economic and social development that needs to provide reference information that will allow us to know the state of soil quality to preserve and manage the public and geoenvironmental health of this region. Anthropogenic activities have contributed to the accumulation of potentially hazardous elements in the environment, affecting various levels of life and creating risks with economic and social implications. However, igneous activity or detrital deposition also enriches soils and creates geochemical anomalies in specific locations. In these cases, the identification of potentially hazardous elements involves the determination of likely sources of contamination and their relationship to the geological setting. In this study, the concentrations of As, Cd, Pb, Mn, Fe, Zn, Hg, Cu and Ni were determined in eighty-one soil samples from the Boyacá industrial corridor (Colombia). The sequential trend of the concentrations of potentially hazardous elements was as follows: Fe > Mn > Zn > Ni > Cu> Pb > As > Cd > Hg. Furthermore, the application of spatial analysis criteria in GIS software with multivariate statistical tools and geochemical indices allowed the identification of anthropogenic and geogenic sources. Most of the potentially hazardous elements were found in soils exposed to industrial and agricultural activities, except for iron. This element showed low variability in all samples, regardless of the geological formations. Due to the lack of reference values for potentially hazardous elements in Colombia, the concentrations were compared with the environmental standards of the Environmental Protection Agency (EPA) and the Ecuadorian Ministry of Environment, Water and Ecological Transition (MAE). The results demonstrate the complexity of the soil and represent the first exploratory study of potentially hazardous elements in this industrial corridor. These results are the starting point for the establishment of geochemical background lines in Colombia and for inspection policies for areas where productive activities converge.

The Yellow River Basin is a complex spatial system integrating ecology, economy, culture and society. The research in this paper takes the innovation of cultural heritage in the basin as the fundamental orientation, and analyzes the influence mechanism of digitization on the innovative development of Yellow River culture through GIS. The inter-regional heterogeneity of the digital transformation of the Yellow River culture is examined through the use of the kernel density function. To examine the spatial correlation between the Yellow River basin and the development of cultural digitalization innovations, the gravity model is utilized. The Yellow River cultural industry’s innovation adaption capacity is measured through two indicators: innovation input capacity and innovation absorption capacity. Based on the analysis of the spatial distribution pattern and the trend of spatio-temporal change, it is tentative to observe that there is a possible spatial correlation between the two. The results show that the field energy variation of the Yellow River cultural memory space ranges from 0.0928 to 0.5384, and the distribution has significant spatial dependence. The logarithm of the digitization level of the Yellow River culture in 2019 is mainly concentrated around -2.2, and the overall digital development of cities along the Yellow River has not been polarized. A new framework and reference for protecting cultural heritage and promoting civilization innovation in the Yellow River basin is provided by this paper.
