Spatially explicit tools are essential for assessing biodiversity and guiding land use decisions at broad scales. This study presents a national-level approach for evaluating habitat quality as a proxy indicator for biodiversity, using Latvia as a case study. The approach integrates land use data, landscape structure, and habitat characteristics to generate habitat quality indices for agricultural and forest land. It addresses a common limitation in biodiversity planning, namely, the lack of consistent species-level data, by providing a comparative and conceptually robust way to assess how different land use types support biodiversity potential. The methodology was applied to assess current habitat quality and to simulate changes under two policy-relevant land use scenarios: the expansion of protected areas and a shift to organic farming. Results showed that expanding protected areas increased the national habitat quality index by 8.47%, while conversion to organic farming produced a smaller but still positive effect of 0.40%. Expansion of protected areas, therefore, led to a greater improvement in habitat quality compared to converting farmland to organic systems. However, both strategies offer complementary benefits for biodiversity at the landscape scale. Although national-level changes appear moderate, their spatial distribution enhances connectivity, particularly near existing protected areas, and may facilitate species movement. This approach enables national-level modelling of biodiversity outcomes under different policy measures. While it does not replace detailed species assessments, it provides a practical and scalable method for identifying conservation priorities, particularly in regions with limited biodiversity monitoring capacity.

To enhance ecosystem services (ESs) benefits and promote ecological–economic–sociologic sustainability in highly urbanized regions such as the Beijing–Tianjin–Hebei (BTH) region, it is essential to assess the dynamic changes in ESs within these regions from a functional zoning perspective and to explore the interactions between ESs. This research delved into how ESs change over space and time, using land-use projections for 2035 based on Natural Development (ND), Ecological Protection (EP), Economic Construction (EC) scenarios. This study also took a close look at the interplay of these ESs across BTH and its five distinct functional zones: the Bashang Plateau Ecological Protection Zone (BS), the Northwestern Ecological Conservation Zone (ST), the Central Core Functional Zone (HX), the Southern Functional Expansion Zone (TZ), and the Eastern Coastal Development Zone (BH). We utilize the Multiple Ecosystem Service Landscape Index (MESLI) to assess the capacity to supply multiple ESs. Key results include the following: (1) Projected land-use changes for 2035 scenarios consistently show cropland and grassland declining, while forest and urbanland expand, though the magnitude of change varies by scenario. (2) Habitat quality, carbon storage, and soil conservation displayed a “high northwest–low southeast” gradient, opposite to water yield. The average MESLI value declined in all scenarios relative to 2020, with the highest value under the EP scenario. (3) Synergies prevailed between habitat quality, carbon storage, and soil conservation, while trade-offs occurred with water yield. These relationships varied spatially—for instance, habitat quality and soil conservation were weakly synergistic in the BS but showed weak trade-offs in the HX. These insights can inform management strategies in other rapidly urbanizing regions. Full article

In recent years, several randomized controlled trials have been published regarding cervical cancer therapy and significantly changed the treatment landscape. Recent advances have improved the treatment options and allow personalized treatment concepts with escalation of treatment in high-risk disease and de-escalation with reduction in morbidity in selected low-risk patients. This review aims to provide a comprehensive analysis of the latest landmark studies that are poised to significantly influence clinical practice. Personalized treatment concepts with careful patient selection allow de-escalation in the surgical treatment of cervical cancer. In low-risk cervical cancer patients (lesions of ≤2 cm with limited stromal invasion), simple hysterectomy (SH) was non-inferior to radical hysterectomy in terms of 3-year incidence of pelvic recurrence and was associated with a lower risk of urinary incontinence or retention and improved sexual health and quality of life. Furthermore, sentinel lymphadenectomy is constantly replacing systematic pelvic lymphadenectomy in patients with low-risk cervical cancer. In addition, further studies are necessary to clarify the role of postoperative therapy for patients with intermediate-risk cervical cancer. Starting in 2008, the EMBRACE studies assess the role of Image guided adaptive brachytherapy (IGABT) in LACC in addition to modern external beam radiotherapy concurrent to chemotherapy. The publication of the results of the EMBRACE I prospective study established MRI guided IGABT as state-of-the-art brachytherapy for LACC. EMBRACE II and additional prospective studies emerging from this consortium will address important questions in modern radiotherapy for LACC. Immune checkpoint inhibitors (CPIs) have been evaluated across various clinical settings and are expected to be utilized in numerous scenarios due to several positive randomized trials. Particularly, the combination of platinum-based chemotherapy and pembrolizumab, with or without bevacizumab, has been established as the new standard treatment for primary metastatic or recurrent PD-L1 positive high-risk cervical cancer. In locally advanced cervical cancer, two new treatment escalation regimens—neoadjuvant chemotherapy and adjuvant CPI therapy—have been evaluated in addition to chemoradiation. Furthermore, antibody-drug conjugates, such as tisotumab-vedotin, represent a promising future therapeutic option for recurrent cervical cancer. Full article

The urban forest canopy provides critical ecosystem services, including carbon storage and sequestration. Healthy, well-managed trees in an urban setting can provide these services in a way comparable to forests managed for production or as nature preserves. Disturbance events threaten these benefits by reducing canopy cover and biomass. A tornado struck Ruston, Louisiana, on 25 April 2019, resulting in severe canopy damage through a swatch of the city. We used iTree Canopy to obtain estimates of ecosystem services (carbon sequestration, etc.) and converted this to a per-pixel value before interpolating for the study area. Fractional vegetation estimates obtained from spectral unmixing were obtained from pre- and post-tornado images using Sentinel-2 data and applied to weight damage. Pre- and post-tornado assessments revealed that Ruston’s urban forest canopy sequestered 85% of its pre-storm capability, with an estimated decline in social value of approximately $36,000. Assessing disturbance-based landscape changes, and subsequently calculating fractional changes in biomass and corresponding monetary impacts, will increasingly be looked to as ecosystem services and severe weather events are expected to become more commonplace in the future. The methodology employed demonstrates a cost-effective way to assess disturbance impacts in small urban areas, offering a framework to small municipalities to monitor canopy dynamics. Full article

In Europe’s changing transport landscape, railways are experiencing a renaissance, driven by environmental advantages, cost efficiency, growing demand, and political support. Yet this growth also exposes major challenges, especially regarding network capacity, infrastructure availability, maintainability, and the cost-effectiveness of maintenance. This study focuses on these aspects, analyzing their interdependence and their impact on building a more resilient and efficient rail system. A prediction model, based on historical measurement data, is developed to forecast track behavior and assess an alternative maintenance strategy. This maintenance strategy uses novel approaches to define maintenance-triggering intervention values. The overarching goal of this work is to contribute to the improvement of predictive maintenance approaches. Findings show no technical or economic justification for the continual reduction of section lengths, a practice common in heavily used networks. Instead, results demonstrate that with improved planning and long-section tamping, both track quality and service life can at least be kept at the same level or even be enhanced. Longer section lengths positively influence performance by lowering running meter costs and potentially reducing operational downtime in the long run. To validate these interrelationship, future research will integrate a model that explicitly considers the costs of operational hindrances. Full article

This study investigates post-fire vegetation transitions and spectral responses in the Snowstorm Fire (2017) and South Sugarloaf Fire (2018) in Nevada using Landsat 8 Operational Land Imager (OLI) surface reflectance imagery and unsupervised ISODATA classification. By comparing pre-fire and post-fire conditions, we have assessed changes in vegetation composition, spectral signatures, and the emergence of novel land cover types. The results revealed widespread conversion of shrubland and conifer-dominated systems to herbaceous cover with significant reductions in near-infrared reflectance and elevated shortwave infrared responses, indicative of vegetation loss and surface alteration. In the South Sugarloaf Fire, three new spectral classes emerged post-fire, representing ash-dominated, charred, and sparsely vegetated conditions. A similar new class emerged in Snowstorm, highlighting the spatial heterogeneity of fire effects. Class stability analysis confirmed low persistence of shrub and conifer types, with grassland and herbaceous classes showing dominant post-fire expansion. The findings highlight the ecological consequences of high-severity fire in sagebrush ecosystems, including reduced resilience, increased invasion risk, and type conversion. Unsupervised classification and spectral signature analysis proved effective for capturing post-fire landscape change and can support more accurate, site-specific post-fire assessment and restoration planning.

Over the past decade, the rapid development of geospatial tools has significantly expanded the scope of archaeobotanical research, enabling unprecedented insights into ancient plant domestication, agricultural practices, and human-environment interactions. Within the Chinese context, where rich archaeobotanical records intersect with complex socio-ecological histories, GIS-driven approaches have revealed nuanced patterns of crop dispersal, settlement dynamics, and landscape modification. However, despite these advances, current applications remain largely exploratory, constrained by fragmented datasets and underutilized spatial-statistical methods. This paper argues that a more robust integration of large-scale archaeobotanical datasets with advanced ArcGIS functionalities—such as kernel density estimation, least-cost path analysis, and predictive modelling—is essential to address persistent gaps in the field. By synthesizing case studies from key Chinese Neolithic and Bronze Age sites, we demonstrate how spatial analytics can elucidate (1) spatiotemporal trends in plant use, (2) anthropogenic impacts on vegetation, and (3) the feedback loops between subsistence strategies and landscape evolution. Furthermore, we highlight the challenges of data standardization, scale dependency, and interdisciplinary collaboration in archaeobotanical ArcGIS. Ultimately, this study underscores the imperative for methodological harmonization and computational innovation to unravel the intricate relationships between ancient societies, agroecological systems, and long-term environmental change.

Efficient water resource management in arid and semi-arid regions is a critical challenge due to persistent scarcity, climate change, and unsustainable agricultural practices. This review synthesizes recent advances in applying remote sensing (RS), geographic information systems (GIS), and machine learning (ML) to monitor, analyze, and optimize water use in vulnerable agricultural landscapes. RS is evaluated for its capacity to quantify soil moisture, evapotranspiration, vegetation dynamics, and surface water extent. GIS applications are reviewed for hydrological modeling, watershed analysis, irrigation zoning, and multi-criteria decision-making. ML algorithms, including supervised, unsupervised, and deep learning approaches, are assessed for forecasting, classification, and hybrid integration with RS and GIS. Case studies from Central Asia, North Africa, the Middle East, and the United States illustrate successful implementations across various applications. The review also applies the DPSIR (Driving Force–Pressure–State–Impact–Response) framework to connect geospatial analytics with water policy, stakeholder engagement, and resilience planning. Key gaps include data scarcity, limited model interpretability, and equity challenges in tool access. Future directions emphasize explainable AI, cloud-based platforms, real-time modeling, and participatory approaches. By integrating RS, GIS, and ML, this review demonstrates pathways for more transparent, precise, and inclusive water governance in arid agricultural regions. Full article

Endemic ectotherms in high-altitude regions face dual threats from climate change and human activities, yet quantifiable indicators to disentangle these stressors remain limited. We developed a novel multi-scenario framework to disentangle the independent and synergistic impacts of climate change and anthropogenic landscape change on the habitat suitability of the Tibetan hot-spring snake (Thermophis baileyi) across the Tibetan Plateau. Our analysis was based on field survey data and species occurrence records, utilizing the species distribution model and the CA–Markov model. We identified temperature seasonality (41.8% contribution) as the primary environmental factor influencing its distribution, followed by precipitation of the coldest quarter (15.1%) and land cover (13.8%). The results showed that moderate climate warming would benefit the survival of the species, with a 24.03–38.55% gain in high-suitability habitat (HSH) area under climate change-only scenarios. However, extreme warming (exceeding SSP5-8.5) would surpass the thermal tolerance threshold of T. baileyi, reducing its HSH and triggering a northward shift in its distribution centroid. Landscape change reduced the HSH (5.98% reduction under land cover change-only scenario), and attenuated climate-driven gains by 4.99–11.31% under combined climate–landscape change scenarios. In addition, only one-fifth of the current HSH was covered by national natural reserves. Synergistic anthropogenic pressures critically offset climate benefits, demonstrating the need for integrated conservation strategies to address the challenges posed by both extreme climate warming and land cover change threats to mitigate future habitat degradation. The quantification of climate–land cover change impacts on T. baileyi offers critical insights for high-altitude ectotherm distributions under global changes and evidence-based conservation planning.

A transition from fossil fuels to renewable energy is underway to achieve net-zero emissions. The institutional arrangements in Indonesia’s energy transportation sector are crucial for various stakeholders involved in the energy transition. This study combines historical institutionalism with a multi-level perspective to analyze how policy formulation, critical junctures, and path dependence shape institutional changes toward sustainable mobility. The evolution of institutional arrangements can be categorized into three phases: the establishment of fuel-oil-based infrastructure and dependency (1970–2003); the diversification of cleaner fuels through compressed natural gas and biofuels (2004–2014); and the development of affordable and clean energy, focusing on biofuels and electrification (2015 to present). In parallel, a quantitative total cost of ownership analysis of vehicles using different fuel types demonstrates how institutional reforms, fiscal incentives, and regulatory support reshape the economic feasibility of low-carbon technologies. Landscape pressures—such as global decarbonization, fuel import dependence, and energy security challenges—interact with niche innovations, including biofuels, electric vehicles, and hybrid systems, to drive systemic transformation. The findings indicate that institutional changes, supported by quantitative economic evidence and technology diffusion, play a pivotal role in realigning Indonesia’s transport energy regime toward a more resilient, inclusive, and sustainable transition.

Understanding how climate change may reshape species distributions and affect the associated ecosystem services is critical for sustainable agricultural planning. In this study, we integrated dietary DNA metabarcoding with ensemble species distribution modeling to assess the current and future ecological roles of Miniopterus fuliginosus, a widespread insectivorous bat species in East Asia known for preying on nocturnal agricultural pests. Fecal samples were collected in 2023 from three biogeographically distinct regions of China—Central China (Henan Province) and Southwest China (Guizhou and Yunnan provinces). DNA metabarcoding based on COI gene amplification and Illumina sequencing revealed a consistent dietary dominance of Lepidoptera, particularly families comprising major agricultural pest species such as Noctuidae, Crambidae, and Geometridae. This trophic consistency suggests that M. fuliginosus functions as a moth-specialized generalist predator. Species distribution models were constructed using occurrence records from field surveys, the literature, and the GBIF database, integrating multiple algorithms (GLM, GBM, MaxEnt, RF, and FDA) within an ensemble modeling framework. Habitat suitability was then estimated under current climatic conditions and projected for future distributions under two contrasting climate scenarios (SSP1–2.6 and SSP5–8.5) for the 2050s and 2070s. While the total suitable area may remain stable or even expand, future projections indicate a progressive poleward shift in range centroids and a divergence in habitat structure. Specifically, SSP1–2.6 is associated with greater spatial cohesion (25.34–31.11%), whereas SSP5–8.5 leads to increased habitat fragmentation and isolation of suitable patches (27.12–33.28%). Overlaying the potential for pest control with habitat projections highlights emerging spatial mismatches between ecological function and climatic suitability, particularly under high-emission trajectories. Our findings underscore the importance of identifying ecological refugia and maintaining landscape connectivity to sustain bat-mediated pest control. This spatially explicit framework offers new insights for integrating biodiversity-based pest management into climate-resilient agricultural strategies. Full article

The study presented in this article explores the changing significance of the river and its impact on shaping the city’s image, using the example of the relationship between the Oder River and the city of Szczecin. The main objective was to examine how the Oder influences Szczecin’s image in the context of sustainable development. The research was based on a historical-interpretative method, employing the analysis of over three thousand postcards depicting the riverside areas of Szczecin from a period of approximately 170 years (1850–2024). The quantitative analysis of postcards was supplemented with an analysis of semantic networks. This approach made it possible to verify how representations of the river on historical postcards reflect the evolution of Szczecin’s urban identity and its connection with the idea of sustainability. The study identified the dominant meanings of the river in different historical periods, as well as characteristic views and distinctive landmarks. This allowed for an assessment of how the Oder was perceived and how these perceptions shaped the city’s image. The results indicate that Szczecin’s image has evolved over time, yet it has always remained rooted in its relationship with the river, dependent on how the Oder was perceived and valued. Today, the river represents not only an essential element of the city’s landscape and cultural identity but also a key component of its contemporary image as a sustainable city. The study contributes to understanding how riverfront imagery shapes perceptions of urban sustainability. Full article

This study presents an integrated framework for spatiotemporal mapping of carbon stocks in rubber plantations in Rayong Province, Eastern Thailand—an area undergoing rapid agricultural transformation and rubber expansion. Unlike most existing assessments that rely on Tier 1 IPCC defaults or coarse plantation age classes, our framework combines annual plantation age derived from Landsat time series, age-specific allometric growth models, and Tier 2 soil organic carbon (SOC) accounting. This enables fine-scale, age- and site-sensitive estimation of both tree and soil carbon. Results show that tree biomass dominates the carbon pool, with mean tree carbon stocks of 66.94 ± 13.1% t C ha⁻¹, broadly consistent with national field studies. SOC stocks averaged 45.20 ± 0.043% t C ha⁻¹, but were overwhelmingly inherited from pre-conversion land use (43.7 ± 0.042% t C ha⁻¹). Modeled SOC changes ($\mathsf{\Delta }\mathrm{SOC}$) were modest, with small gains (2.06 t C ha⁻¹) and localized losses (−9.96 t C ha⁻¹), producing a net mean increase of only 1.44 t C ha⁻¹. These values are substantially lower than field-based estimates (5–15 t C ha⁻¹), reflecting structural limitations of the global empirical ΔSOC model and reliance on generalized default parameters. Uncertainties also arise from allometric assumptions, generalized soil factors, and Landsat resolution constraints in smallholder landscapes. Beyond carbon, ecological trade-offs of rubber expansion—including biodiversity loss, soil fertility decline, and hydrological impacts—must be considered. By integrating methodological innovation with explicit acknowledgment of uncertainties, this framework provides a conservative but policy-relevant basis for carbon accounting, subnational GHG reporting, and sustainable land-use planning in tropical agroecosystems.

By combining social, ecological, and communal elements, urban parks significantly improve the quality of urban life. This paper explores the revitalization proposal for Areos Park in Tripoli, Greece, viewing it as an urban palimpsest reflecting layers of history, culture, and nature. While historically evolving from exclusive enclaves to vital public spaces fostering social equity and well-being, many urban parks, including those in Greece, suffer from neglect and underfunding, diminishing their landscape value and necessitating revitalization. Areos Park exemplifies these challenges, making it an ideal case study for exploring effective urban park revitalization strategies and demonstrating how urban areas can host critical landscape functions. Utilizing a design-based research (DBR) methodology, a design plan is proposed. The architectural concept focuses on revamping key areas, restoring historical features, adding small constructions, and repurposing existing buildings for community and educational uses. Concurrently, the landscape concept emphasizes biodiversity enrichment and ecological restoration through permeable surfaces and native Mediterranean vegetation, contributing to urban resilience to climate change. The overall design prioritizes accessibility and spatial connectedness to create an inclusive, resilient, and adaptable urban park addressing contemporary sustainability challenges and biodiversity loss. The project aims to establish Areos Park as a model for sustainable urban park regeneration in small cities, blending ecological enhancement with historical preservation. Full article

Arterial hypertension (HTN) represents the major cardiovascular risk factor and still represents a global health issue. In the last two years, three international societies published the new guidelines for the treatment of HTN (European Society of Cardiology, 2025; European Society of Hypertension, 2023; and American College of Cardiology in collaboration with American Heart Association, 2025), with many novelties which have been the object of many discussions among experts. The increased stress on screening programs, the new lower targets to reach by medical treatment, and the new strategies for resistant hypertension have raised some doubt on the feasibility of these recommendations in clinical practice. In this perspective document, the authors highlight and discuss the novelties and potential pros and cons of the new international recommendations for the treatment of arterial HTN. Full article
