Sutureless aortic valve replacement (SuAVR) has emerged as a potential alternative to conventional surgical aortic valve replacement (SAVR), particularly in minimally invasive settings. However, its global adoption remains limited, with a notable concentration of use and scientific production in select European countries. This bibliographic meta-analysis systematically reviewed 538 studies to assess the evidence landscape surrounding SuAVR, highlighting a predominance of observational data, sparse randomized controlled trials (1.3%), and significant geographical imbalances in research output. Europe accounted for 80% of publications, while North America contributed less than 10%. Key structural factors—including reimbursement policies, earlier regulatory approvals, and population characteristics—appear to influence SuAVR adoption. Despite procedural advantages such as reduced cross-clamp times, concerns over cost, pacemaker implantation rates, and uncertain long-term durability persist. Importantly, SuAVR may offer its greatest clinical value by facilitating minimally invasive surgery, a niche still underutilized worldwide. The limited randomized data and industrial focus on transcatheter approaches have further hindered widespread acceptance. Our findings underscore the need for high-quality comparative trials and standardized guidelines to define the role of SuAVR in modern valve therapy. Full article

The ocean plays a vital role in our society and represents a constantly changing landscape that is not well understood and therefore needs continuous monitoring and research. Sustainable monitoring is essential to assess both the current and future state of our oceans. However, conventional monitoring faces significant challenges, including issues of accessibility, and spatial and temporal constraints. The development of digital twins of the ocean (DTO) offers an emerging technology that could revolutionise our understanding of marine and coastal environments. Current DTO have shown effectiveness in monitoring marine and coastal environments in the European context. However, there is a need for a DTO for the Southern African and Western Indian Ocean regions that addresses specific concerns that are relevant to these regions. Successful development of a DTO depends on the availability of high-quality data. Therefore, various data inputs are necessary to build an accurate digital twin. This paper explores the data that can be utilised in a DTO, detailing how different ocean variables are collected and integrated into the digital twin. As a first step towards the development of a DTO in these regions, the paper proposes a data management plan and its implementation in the development of DTO. The data management plan is based on the phases of data in a geospatial data life cycle. Challenges regarding the management of data in this DTO and possible solutions are presented in the conclusion. Full article

Over the centuries, the reclamation of marshy areas has significantly transformed the Italian rural landscape. The Piana di Sibari (North of Calabria) represents a paradigmatic case of this process, because the current landscape is the result of a vast rural transformation. This paper discusses the results of a survey conducted to evaluate students’ knowledge and perception of this “Reclaim Lands” landscape, focusing on their emotional connection and awareness of its cultural and environmental heritage. The survey was administered to 149 middle school and 177 high school students. The study aims to investigate awareness and perception of landscape among mid-to-late adolescents living in the Piana di Sibari, highlighting the key aspects of the relationship between students and the places they inhabit, recognizing the catalytic role of the landscape in fostering a sense of belonging and identity. The results of this survey encourage reflection on a cultural shift that integrates ecological, social, and cultural perspectives, aligned with the European Landscape Convention, advocating for greater investment in youth education and participation to promote active citizenship and chart a course toward a fairer and more sustainable society.

The European Landscape Convention (ELC) acknowledges that the landscape is an important part of the quality of life for people everywhere, in urban areas and the countryside, in degraded areas as well as higher quality areas and recognized as being of outstanding beauty, as well as in everyday areas. Nowadays, many suburbs, arisen as public housing neighborhoods and originally located in peri-urban areas, in addition to constituting a substantial part of the built heritage, are increasingly being configured as new strategic areas, redefining the daily landscape of its users. With the post-occupancy evaluation method (POE), it is possible to assess several aspects of the performance of buildings or open spaces from the users’ perspective, taking into consideration objective and subjective factors. It is a multi-method approach, combining interviews, customer satisfaction surveys, behavioral observation, etc. With this perspective, the article, dealing with the ‘Parco dei Murales’, which is a complex of public housing localized in the Ponticelli suburb in the city of Naples (Italy), aims to understand the visual and qualitative perception of the suburban landscape in the light of the transformation processes that have occurred in recent years. For this purpose, starting from the results of the first application of a user satisfaction survey, the post occupancy evaluation has been applied, analyzing the functional, social, and perceptual attributes of the open spaces of the park.

The article focuses on the development of a universal method for the appraisal of values of a natural landscape in administrative division units. The Dobre Miasto municipality serves as a case study. The municipality lies in the heart of Warmia, a region with centuries-long historical tradition. This paper also mentions solutions adopted in Poland in the consequence of the ratification of the European Landscape Convention. Following many years of research, changes in the natural landscape and directions in the measures taken to protect it were traced. In the face of current transformations in space, efforts to protect and conserve natural wealth are difficult. Compromises are unavoidable for the sake of saving the region’s valuable natural assets while allowing its development. The aim of this study was to identify the natural values in the chosen research area, and to develop a method for their appraisal. The identification of the natural elements deserving protection substantiated rational location decisions in space. This is particularly important in the case of a natural landscape, which is difficult to evaluate and whose estimated value is often a result of a subjective assessment. The valorisation of the natural landscape in the chosen municipality allowed us to identify new areas, which at present are outside the boundaries of legally protected areas but which deserve protection owing to their highly valuable natural properties. The proposed method for the appraisal of natural values can be used in shaping a spatial policy, in spatial planning and development, and, above all, in the preparation of landscape audits. The proposed method fills the gap in the legal regulations adopted in Poland in the field of strengthening the protection of natural and cultural values since no comprehensive guidelines for the evaluation of landscape attributes for the purposes of landscape protection and development have been elaborated thus far.

Incorporating sewage sludge (SS) into soils presents a cost-effective and environmentally friendly option compared to conventional farming practices. However, SS could be perceived as a double-edged sword, as it may contain a broad spectrum of contaminants, such as heavy metals (HMs), microplastics (MPs), Pharmaceuticals in the Environment (PIE), and personal care products (PSPs), raising concerns for soil health, water resources, food safety, and human health. Council Directive 86/278/EEC, which regulates SS application in agriculture, specifies limits for six HMs but has not undergone substantive revisions since its inception in 1986, until the release of the updated working document SWD-2023-{final 158}. This study critically examines the legislative landscape across the European Union (EU) Member States (MSs), identifying heterogeneity in implementation, regulatory gaps, and the absence of thresholds for emerging contaminants. The results reveal significant disparities in the permissible concentrations of HMs across MSs and in comparison to international guidelines established by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). Furthermore, the absence of regulatory measures for MPs, PIE, and other common soil pollutants underscores critical deficiencies in the current framework. These inconsistencies contribute to varying levels of soil health across the EU and highlight the need for a harmonized approach. The findings of this study highlight the imperative for a comprehensive overhaul of the EU legislative framework governing SS application. As evidenced, the establishment of harmonized contaminant thresholds, rigorous monitoring protocols, and regulatory provisions for emergent pollutants is essential for addressing the identified regulatory gaps, enhancing legislative coherence, and promoting sustainable agricultural practices aligned with the EU’s environmental and public health objectives.

The rapid global transition toward renewable energy necessitates innovative solar PV deployment strategies beyond conventional roof installations. In this context, commercial building facades represent an expansive yet underutilized resource for solar energy harvesting in urban areas. However, existing studies on commercial rooftop solar PV predominantly focus on European contexts, neglecting the unique design constraints and performance trade-offs present in regions such as the Middle East. This study addresses this gap by specifically investigating the impact of architectural and structural features on the utilizable facade area for PV deployment in commercial buildings within the hot desert climate of Saudi Arabia. Detailed case studies of twelve representative buildings are conducted, combining architectural drawing analysis, on-site measurements, and stakeholder surveys. The methodology identified sixteen parameters across three categories—facade functionality, orientation suitability, and surrounding obstructions—that impose technical and non-technical restrictions on photovoltaic integration 3D modeling, and irradiance simulations revealed that, on average, just 31% of the total vertical facade area remained suitable for PV systems after accounting for the diverse architectural and contextual limitations. The study considered 698 kWh/m² of solar irradiance as the minimum threshold for PV integration. Shopping malls displayed the lowest utilizability, with near-zero potential, as extensive opaque construction, brand signage, and shading diminish viability. Offices exhibited the highest utilizability of 36%, owing to glazed facades and unobstructed surroundings. Hotels and hospitals presented intermediate potential. Overall, the average facade utilizability factor across buildings was a mere 16%, highlighting the significant hurdles imposed by contemporary envelope configurations. Orientation unsuitability further eliminated 12% of the initially viable area. Surrounding shading contributed an additional 0.92% loss. The results quantify the sensitivity of facades to aspects such as material choices, geometric complexity, building form, and urban context. While posing challenges, the building facade resource holds immense untapped potential for solar-based urban renewal. The study highlights the need for early architectural integration, facade-specific PV product development, and urban planning interventions to maximize the renewable energy potential of commercial facades as our cities rapidly evolve into smart solar energy landscapes.

Universities play a pivotal role in modern society and must lead the way in achieving energy efficiency, directly contributing to the Sustainable Development Goals (SDGs). Like small towns in resource consumption and population mobility, many universities and research centers face significant challenges transitioning to renewable electricity systems. This study aims to (i) map the current scientific literature on renewable energy sources used by universities; (ii) discuss the drivers, barriers, and trends of implementing renewable energy; and (iii) establish a connection with the SDGs. More specifically, the authors conducted a systematic literature review based on three stages: (i) data collection, (ii) bibliometric analysis, and (iii) content analysis. Forty-two articles were obtained and defined as the studied sample. The findings of this review illuminate critical research themes, leading countries in renewable energy adoption, and the prevalent electricity sources, shedding light on the primary authors shaping the discourse. Wind and solar energy exhibit a notable growth trajectory, offering environmentally friendly alternatives compared to conventional sources. Furthermore, it is essential to highlight that the distribution of research documents in the sample is uneven, with a predominant concentration in European countries. Additionally, the study identifies the field’s key drivers, barriers, and emergent trends. The theoretical contributions encompass a comprehensive compilation of renewable energy sources, discernible research trajectories, and strategies to navigate obstacles. In practical terms, this work offers valuable insights for the selection of energy sources and stakeholder engagement, facilitating informed decision-making processes. This article’s novelty lies in its holistic examination of renewable energy adoption in university settings, providing a comprehensive overview of the current landscape and actionable insights for stakeholders seeking sustainable energy solutions within these institutions. This aligns with multiple SDGs, including Goal 7 (Affordable and Clean Energy), Goal 11 (Sustainable Cities and Communities), and Goal 13 (Climate Action), underscoring the critical role of universities in driving sustainable development.

The Green Deal, a cornerstone of the European Union’s climate goals, sets out to achieve a substantial 55% reduction in greenhouse gas emissions by 2030 compared to 1990 levels. The EU’s decarbonization strategies revolve around three pivotal avenues. First, there is a focus on enhancing energy efficiency and decreasing the energy intensity of economies. Second, concerted efforts are made to diminish the reliance on fossil fuels, particularly within industrial sectors. Lastly, there is a deliberate push to augment the share of renewable energy sources in the final energy consumption mix. These measures collectively aim to propel the decarbonization of EU economies, establishing EU member countries as global leaders in implementing these transformative processes. This manuscript seeks to evaluate the efficacy of three primary decarbonization strategies adopted by EU economies, namely the enhancement in energy efficiency, the promotion of renewable energy consumption and the reduction in fossil fuel consumption. The objective is to discern which strategies wield a decisive influence in achieving decarbonization goals across EU countries. The analysis encompasses all 27 member states of the European Union, spanning from 1990 to 2022, with data sourced from reputable outlets, including Eurostat, Our World in Data and the Energy Institute. Research findings underscore that, in the realm of decarbonization policies, statistically significant impacts on carbon dioxide emission reduction are attributable to the strategies of improving energy efficiency and augmenting the share of renewables in energy consumption across almost all EU countries. Conversely, the strategy with the least impact, embraced by a minority of EU member states, revolves around diminishing the share of fossil fuels in primary energy consumption. This approach, while statistically less impactful, is intricately linked with transitioning the economies toward renewable energy sources, thus playing a contributory role in the broader decarbonization landscape. The uniqueness of this research lies not only in its discernment of overarching trends but also in its fervent advocacy for a comprehensive and adaptive approach to EU decarbonization policy. It underscores the enduring significance of prioritizing energy efficiency, endorsing the integration of renewable energy and acknowledging the distinctive dynamics inherent in diverse regions. The study accentuates the necessity for nuanced, region-specific strategies, challenging the conventional wisdom of a uniform approach to decarbonization. In doing so, it accentuates the critical importance of tailoring policies to the varied energy landscapes and transition strategies evident in different EU member states. Full article

The European Landscape Convention promotes the protection, management and planning of landscapes and organises international co-operation on landscape issues. Member states committed to implement measures such as promoting social education about landscapes. The convention stated that, although it was part of the education curricula in some countries, landscape education was to be expanded from a multidisciplinary perspective. The Education Act in force in Spain in 2008 (LOE, 2007), when the convention was ratified, included landscape in the syllabus, but not from as broad a perspective as that reflected in the ELC. Later education reforms have gradually increased the presence of the landscape in school curricula. This study examines landscape-related knowledge and awareness among current trainee primary school teachers, whose whole education has occurred under the umbrella of the ELC. This aims to assess whether the ELC’s targets have been met in terms of social awareness of landscape issues. A mixed questionnaire was designed, validated, and implemented in a sample of 322 students studying subjects related to the teaching of geography. The answers were analysed with descriptive and inferential statistics. The results reflect poor landscape-related knowledge and awareness, suggesting that the educational measures implemented since the ratification of the ELC have not been successful. Full article

Climate change has increasing impacts of hydro-meteorological extremes on water resources. Projections indicate a similar trend and challenge in the effectiveness of conventional engineering solutions in climate change adaptation (CCA) and disaster risk reduction (DRR) strategies. Nature-based solutions (NbSs) have been promoted as viable approaches and measures that complement engineering solutions. While the effects of NbSs have been increasingly demonstrated, their broader implementation can be favoured by NbSs knowledge integration in higher education curricula. Knowledge on how the research practice is translated into the educational landscape is missing. This paper adopts the concept of knowledge translation and analyses the integration of NbSs in the study programs of higher education institutions in three European countries (Croatia, Czechia, and Slovenia). Specifically, it explores the extent, thematic areas, and curricular settings of NbSs related to water resources management in implemented curricula at public universities. The results show that NbSs are integrated in a limited number of courses within the relevant study programs (in the fields of, e.g., natural sciences, geography, and engineering and technology) and represent rather an extension of compulsory curricula. Bibliometric analysis revealed that most courses involving the NbSs approach still represent a personalized knowledge, i.e., developed by professors during their research activities. The barriers impairing a broader integration of NbSs in the studied programs are then discussed. Our results therefore indicate that NbSs do not represent a mainstream knowledge that would proliferate into higher education curricula through accreditations procedures, but that the knowledge that is mostly integrated through direct incremental implementation of NbSs in the individual compulsory lessons or facultative courses. We assert that without broader and systematic NbSs knowledge translation to study programs, the effectiveness of climate change adaptation and disaster risk reduction strategies cannot be fully achieved.

Rabbit haemorrhagic disease virus (RHDV) is established as a landscape-scale biocontrol that assists the management of invasive European rabbits and their impacts in both Australia and New Zealand. In addition to this, it is also available to land managers to augment rabbit control efforts at a local scale. However, current methods of deploying RHDV to rabbits that rely on the consumption of virus-treated baits can be problematic as rabbits are reluctant to consume bait when there is abundant, green, protein-rich feed available. We ran a suite of interrupted time-series experiments to compare the duration of infectivity of two conventional (carrot and oat baits) and two novel (meat bait and soil burrow spray) methods of deploying RHDV to rabbits. All methods effectively killed exposed rabbits. Soil burrow spray and carrot baits resulted in infection and mortality out to 5 days post their deployment in the field, and meat baits caused infection out to 10 days post their deployment. In contrast, oat baits continued to infect and kill exposed rabbits out to 20 days post deployment. Molecular assays demonstrated high viral loads in deployed baits beyond the duration for which they were infectious or lethal to rabbits. Based on our results, we suggest that the drying of meat baits may create a barrier to effective transmission of RHDV by adult flies within 10 days. We therefore hypothesise that fly larvae production and development on infected tissues is critical to prolonged viral transmission from meat baits, and similarly from carcasses of RHDV mortalities, via mechanical fly vectors. Our study demonstrates that meat baits and soil spray could provide additional virus deployment options that remove the need for rabbits to consume baits at times when they are reluctant to do so.

The internationally accepted goal of eliminating climate gas emissions implies substantial investments in renewable energy (RE) facilities. This will inevitably lead to major impacts on landscapes. Landscape concerns linked to RE facilities are already leading to controversies in many local communities. In this article, we focus on the question of landscape democracy related to the establishment of RE facilities. Based on recommendations from the European Landscape Convention, an analytical framework is presented identifying three main dimensions of landscape democracy, followed by an overview of arrangements, procedures, and methods that are or may be used to encourage democracy. The procedures and methods are analyzed based on examples from Denmark and Norway. This is followed by an analysis of decision levels with a special focus on the principle of subsidiarity. Finally, recommendations are presented to strengthen landscape democracy in relation to the installation of RE facilities. Full article

Pursuing sustainability in a challenging world and under the influence of numerous natural and anthropogenic drivers of change presents one of the major global concerns. The transition towards a more sustainable development requires a harmonious balance between human well-being and environmental management. The concept of landscape is at the core of such a process. Hence, evaluating the different aspects of the landscape and their components is crucial for policy making, planning and management. In fact, landscape quality assessment has become a special focus of interest, especially with the directives of the European Landscape Convention. This research work aims to analyze the rural landscape of the Chania prefecture, West Crete, Greece, taking into account its multifold dimensions. The analysis was carried out using a series of quantitative spatial indicators. Consecutively, structural (mean patch area, contagion index, edge density and percentage of landscape occupied by a class of the highest share), ecological (density of ecological barriers, Modified Shannon diversity index), visual (share of positive land-cover forms, share of negative land-cover forms, form and color disharmony index, shape disharmony index) and cultural indices (historical monuments index) were estimated and analyzed in a GIS environment. The overall methodology incorporated different land-use/land-cover data (multitemporal Corine data and land use derived from the classification of Earth-observation (EO) data). The historical and current analysis of the landscape within Chania revealed quite high structural and visual values. The ecological dimension is rather stable, with a potential decrease by the year 2045. Additionally, the structural dimension seemed to be sensitive to the spatial resolution of the data source. The spatial extent, at which the landscape is evaluated, seemed to impact the landscape’s ecological, visual and cultural values. Full article

The integration of landscape-based approaches into regional and town planning policies is one of the main objectives of the European Landscape Convention. In the twenty-first century, the traditional discipline of city spatial-planning has gradually been incorporating two types of tactics linked to a landscape-based approach: nature-based strategies, which focus on sustainable goals; and people-based strategies, which integrate a social dimension into decision-making processes. A backbone of landscape-based spatial planning challenge consists of reshaping consolidated urban areas to improve quality of life, encouraging people’s physical activity, and supporting healthier urban lifestyles. This study assumes that physical activity is further encouraged by itineraries that incorporate both landscape features—i.e., natural assets and sense of place—and functional diversity associated with urban activities—i.e., public facilities. A methodology was elaborated to define a preliminary landscape-based spatial planning approach, centering on the analysis of walking-related activity in urban and peri-urban areas. For this purpose, geolocated digital traces are intertwined: official city routes, urban facility locations, users’ Wikiloc trails, and Google Places API data. Once applied to selected medium-sized European cities in the Mediterranean area, these data sources lead to the identification of intangible values and dynamics in places where landscape-based spatial planning solutions could be enhanced. As a result, the present work shows the suitability of interrelating these geolocated data sources, permitting to identify landscape features as key components of spatial planning, which permit balancing individual goals, the aims of local communities, and administrative functions.
