Macrophytes are important components of aquatic ecosystems performing essential ecological functions. Their species composition and density reflect the ecological status of water bodies. The optimal ratio of morphological types of macrophytes is an important condition for preventing eutrophication. The aim of the study is to analyse the species composition, distribution, and density of macrophytes in the Vyzhyvka River (Ukraine) in a seasonal aspect (2023–2024) under constant physical and chemical characteristics of water. To assess the seasonal dynamics of water quality, changes in indicators in three representative areas were analysed. The MIR method of environmental indexation of watercourses was used to assess the ecological state of the river. The water quality in the Vyzhyvka River at all test sites corresponds to the second class of the “good” category with the trophic status of “mesotrophic”. This is confirmed by the identified species diversity, which includes 64 species of higher aquatic and riparian plants. Among the various morphological types of macrophytes, submerged rooted forms account for only 10.56% of the total species composition. To ensure a functional balance between submerged and other forms of macrophytes, a scientifically based approach is proposed, which involves the use of mineral raw materials of local origin, in particular, mining and quarrying wastes rich in silicon, calcium and other mineral components. The results obtained are of practical value for water management, environmental protection, and ecological reclamation and can be used to develop effective measures to restore river ecosystems.

Applicable recommendations play a key role in improving training and procedures used in civil protection. Since 1 January 2025, the Law on Civil Protection and Civil Defense has been in force in Poland. It responds to the experience of current threats, including the war in Ukraine, the 2024 floods in Western Poland, the COVID-19 pandemic, and other crises. The Act systemically regulates the problem of building social resilience, which must be developed and applied regarding today’s modern threats. The primary actor in civil protection is the fire brigade system, in which volunteer firefighters are recruited from local communities and act for their benefit. In this context, it is interesting to ask whether and what solutions should be applied in order to improve the effectiveness of the training and exercise system of volunteer fire brigades (TSOs) in the field of civil protection and crisis management. The aim of this investigation was to develop evaluations and applicable recommendations to improve the effectiveness of the training system for volunteer firefighters based on a survey of volunteer firefighters in the Cracow Poviat. Two survey diagnostic techniques were used: expert interviews and questionnaire research. The findings were compared with the results of an analysis of source documents obtained in TSO units. The expert interviews covered all chief fire officers of the municipalities in the Cracow Poviat. The paper begins with an introduction and a systematic literature review. The conclusions consist of the proposal of applicable changes in the scope of basic, specialist, and additional training. Areas of missing training are also identified. The firefighters’ knowledge of crisis management procedures is verified, deficiencies are identified, and applicable changes in the organization of field exercises are proposed. Full article

This article examines the role of religion in Russia’s national security system through the lens of ontological security, assessing whether contemporary Russia is undergoing a process of desecularisation or, conversely, an intensified form of secularisation. Employing the theoretical framework of ontological security, this study argues that Russia’s securitisation of religion serves as a mechanism for consolidating state control, legitimising authoritarian governance, and constructing a distinct civilisational identity in opposition to Western liberalism. The Russian Orthodox Church, rather than functioning as an autonomous religious institution, has been absorbed into the state apparatus, where it operates as an instrument of state ideology. Religious rhetoric permeates Russian strategic security documents, reinforcing narratives of national exceptionalism, historical continuity, and moral superiority, particularly in justifying Russia’s geopolitical ambitions and military actions, including its war against Ukraine. The analysis challenges prevailing interpretations of religious resurgence in Russia, arguing that the increasing presence of religion in public life does not necessarily signify desecularisation. Instead, the instrumentalisation of religion for political and security purposes suggests a process of extreme secularisation, wherein religious institutions lose their autonomy and doctrinal substance, becoming tools of state power.

Russia’s conflict with Ukraine, which escalated into full-scale military confrontation in February 2022, originated in 2014 with the annexation of Crimea and the backing of pro-Russian separatists in Donetsk and Luhansk. However, this war extends beyond bilateral hostilities, reflecting a broader geopolitical confrontation with the West that aligns with Vladimir Putin’s strategic vision, as signalled in his 2007 Munich Security Conference speech. Russian security doctrines have consistently framed the West as an existential threat, a perception reinforced by state-controlled media. This study examines the role of Russian state media in shaping public perceptions of the West between 2014 and 2022. It explores how Russian media, particularly RIA Novosti, constructed adversarial narratives about Latvia, Poland, and Serbia within the framework of Russian security policy. Through qualitative content analysis, the research investigates the alignment of media narratives with official strategic objectives, the portrayal of Western nations as threats, and the intended audience of these narratives. The findings underscore the integral role of state-controlled media in Russia’s security strategy, highlighting an increasing consolidation of media control to sustain domestic legitimacy and justify external aggression. As Russia faces growing challenges, media restrictions are expected to intensify, reinforcing state-driven narratives and information isolation. Full article

This paper examines the phenomenon of collaborative consumption among Generation Z in Ukraine, focusing on its significance for sustainable consumption and the factors driving its popularity. In the context of increasing digitalization and environmental challenges, the authors analyze the extent to which young Ukrainians engage in the sharing economy and the motivations behind their choices. Special attention is given to the unique characteristics of Generation Z in Ukraine, who, unlike their Western peers, are marked by a strong sense of patriotism, greater social responsibility, and a desire for economic stability—factors influenced by the country’s challenging geopolitical situation. The study was conducted using an online survey (CAWI) with a sample of 292 respondents in 2024. The results indicate that 54.8% of the respondents show a propensity for collaborative consumption (PCC), with key motivators being convenience (90%), the need for social connections (70%), and environmental awareness (68%). Individuals inclined toward resource sharing tend to exhibit greater openness, loyalty, and innovativeness. However, the lack of significant differences in their broader sustainable consumption behaviors suggests that collaborative consumption is perceived primarily as a practical solution rather than a consciously pro-environmental strategy. These findings have important practical implications—companies should focus on building trust in sharing platforms, offering flexible pricing models, and emphasizing both financial savings and environmental benefits. Meanwhile, policymakers can support the growth of the sharing economy through regulations that foster innovation and educational campaigns promoting sustainable consumer behavior. Full article

Climate-induced hydrological risks and deteriorating infrastructure present major challenges for small river basins in border regions, particularly in non-EU countries with limited institutional capacity and funding. These issues are especially acute in post-socialist contexts, where outdated hydrotechnical systems no longer meet current environmental and safety standards. This study investigates the vulnerabilities of the Uzh River basin in Uzhhorod, Ukraine—a non-EU border city with strong ecological and institutional ties to neighboring EU regions—and proposes an adaptive river management model tailored to such environments. An integrated assessment of flood protection systems, sediment transport, drainage performance, and governance gaps was conducted to inform the proposed framework, which combines structural and ecosystem-based interventions with a focus on transboundary water governance. Unlike many existing approaches that lack mechanisms for localized implementation and cross-border coordination, this model offers a transferable, evidence-based methodology for enhancing flood resilience and hydrological sustainability in similar urban areas. The insights are relevant to border cities across Eastern Europe, the Western Balkans, and the South Caucasus, contributing to both engineering practice and regional policy by aligning hydrotechnical solutions with cooperative climate adaptation strategies.

Elms (Ulmus spp.) are widely spread in the forest, shelter belts, and urban landscaping. This research aimed to reveal the trends of Ulmus sp. health in Ukraine under biotic damage. The tasks included: (i) analyzing the presence of Ulmus sp. in the forests; (ii) studying the dynamics of Ulmus sp. health for 2001–2015 in the monitoring plots in the frame of the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP-Forests); (iii) assessing the prevalence of the dominant biotic factors affecting elm health and the probability of tree death or recovery. As a result of research, elms were found in 3.58% of the area in the stands with other main forest-forming species in the forests subordinated to the State Specialized Forest Enterprise «Forests of Ukraine». Four elm species are present in the forests of all regions of Ukraine. In the Forest zone, U. minor predominates, U. glabra is more common in the western part of the country, and U. pumila in the southern and eastern regions. In the ICP-Forests monitoring plots for 2001–2015, a trend of elm deterioration in 2007–2012 was found. The highest incidence of trees with disease symptoms was recorded for U. pumila. In the sample plots for 2023–2024, the health of three elm species tended to deteriorate. In 2024, mortality occurred among all elm species with symptoms of Dutch elm disease (DED) and among U. pumila trees with symptoms of wetwood. However, several trees have recovered. The results show the gaps in our knowledge that need to be filled, particularly in identifying resistant individuals and using their progeny to create resistant stands. Full article

The Ukrainian parliament’s 2024 law banning the Ukrainian Orthodox Church of the Moscow Patriarchate (UOC-MP) marks a significant conceptual and strategic recalibration of the Russian Orthodox Church’s (ROC) geopolitical culture. The framework of the “Russian world” project, which asserted a shared civilizational identity between Russia and its Orthodox neighbors, is increasingly untenable amidst the war with Ukraine and splits in the Orthodox world. In response, the ROC has pivoted towards global outreach, notably expanding into Africa. This move aligns with Russia’s broader geopolitical strategy, which frames Russia as a defender of multipolarity and traditional values against Western influence. However, the ROC’s attempt to adopt a global stance and reimagine itself as a universal church, rather than a pillar of the “Russian civilization”, faces ideological and geopolitical challenges, as explored in the paper.

The outbreak of Russia-Ukraine conflict casted an impact on the global food market, which was believed to be attributed to that Ukraine has suffered significant production losses due to cropland abandonment. Nevertheless, recent outbreaks of farmer protests against Ukraine’s grain exports demonstrated that the production losses might not be as severe as previous estimates. By utilizing the adaptive threshold segmentation method to extract abandoned cropland from the Sentinel-2 high-resolution imagery and calibrating the spatial production allocation model’s gridded crop production data from Ukraine’s statistical data, this study explicitly evaluated Ukraine’s crop-specific production losses and the spatial heterogeneity. The results demonstrated that the estimated area of abandoned cropland in Ukraine ranges from 2.34 to 2.40 million hectares, constituting 7.14% to 7.30% of the total cropland. In Ukrainian-controlled zones, this area spans 1.44 to 1.48 million hectares, whereas in Russian-occupied areas, it varies from 0.90 to 0.92 million hectares. Additionally, the total production losses for wheat, maize, barley, and sunflower amount to 1.92, 1.67, 0.70, and 0.99 million tons, respectively, with corresponding loss ratios of 9.10%, 7.48%, 9.54%, and 8.67%. Furthermore, production losses of wheat, barley, and sunflower emerged in both the eastern and southern states adjacent to the conflict frontlines, while maize losses were concentrated in the western states. The findings imply that Ukraine ought to streamline the food transportation channels and maintain stable agricultural activities in regions with high crop production. Full article

Marennine is the specific bluish pigment produced by the marine diatom Haslea ostrearia Gaillon (Simonsen), responsible for the greening of oysters in France’s Atlantic coast. For decades, H. ostrearia was considered the only blue diatom and described as such. However, new blue Haslea species have been described recently, among which Haslea karadagensis Davidovich, Gastineau, and Mouget (Black Sea, Crimea, Ukraine); Haslea provincialis Gastineau, Hansen, and Mouget (Mediterranean Sea, southern France); Haslea silbo Gastineau, Hansen, and Mouget (West Atlantic Ocean, USA); and one not characterized yet, Haslea sp. nov., isolated in Tenerife (Spain). These species produce marennine-like pigments, for which little information is available yet. The present work aims at studying spectral characteristics of these pigments by UV–visible spectrometry, Raman spectrometry, infrared spectrometry, nuclear magnetic resonance, energy-dispersive X-ray spectroscopy, and cyclic voltammetry, and comparing them to those of marennine produced by H. ostrearia strains originating from the north Atlantic Ocean (western France and Macaronesia), and north Pacific Ocean (southwestern USA). Results show that marennine produced by H. ostrearia strains and marennine-like pigments produced by H. provincialis, H. silbo, and Haslea sp. nov. are quite similar regarding their polysaccharide skeleton, and absorption in the UV–visible, infrared, and Raman regions. The most different marennine-like pigment is produced by H. karadagensis, but all Haslea blue pigments studied so far belong to the same family of organic molecules. Full article

This article explores the pervasive influence of conspiracy theories, specifically the New World Order (NWO) and Golden Billion theories, within the context of the ongoing conflict between Russia and Ukraine. These theories form key narrative frameworks in Russian state media and global conspiracy communities, shaping perceptions of geopolitical events. This study dissects four pivotal episodes within the Russia–Ukraine conflict to illustrate how conspiracy theories shape public perception and policy direction, further entrenching ideological divides. In the first episode of the 2022 full-scale invasion, narratives of the Golden Billion were utilised to justify the attack, presenting Russia as a bastion against the Western elite’s plans to dominate the global economy and resources. The second episode examines the attack on Mariupol in 2022, framed by Russian propaganda as a necessary act to thwart the supposed expansion of NATO and the EU, underpinned by the NWO agenda aiming to dilute Russian influence in Eastern Europe. The third episode analyses the Nord Stream pipeline sabotage in 2022, interpreted by some conspiracy theorists as an act by the NWO to destabilise Europe’s energy security, thus consolidating control over energy routes and resources. The fourth episode delves into the 2024 Moscow terrorist attacks, which were seen by some as either a false flag operation conducted by Western powers or as a legitimate repercussion of Western encroachment orchestrated to weaken Russia’s resolve and international standing. Each episode is contextualised within a broader conspiratorial framework, highlighting the dualistic nature of the NWO and Golden Billion theories that paint the conflict not merely as territorial disputes but as a clash between fundamentally opposing worldviews and global orders. This narrative analysis not only underscores the role of conspiracy theories in shaping geopolitical discourse but also demonstrates their utility in mobilising domestic support, framing international criticism, and justifying military actions. Our findings suggest that these conspiratorial narratives provide a resilient, albeit misleading, lens through which supporters of the Kremlin’s policies can rationalise the war, attributing complex sociopolitical dynamics to the malevolent machinations of a global elite. This study contributes to understanding how modern conflicts are interpreted through ancient conspiratorial lenses, impacting national and international policy and public opinion. Full article

This study investigates the profound and multifaceted impacts of Artificial Intelligence (AI) and geopolitical developments on global dynamics by 2040. Utilising a Delphi process coupled with probabilistic modelling, the research constructs detailed scenarios that reveal the cascading effects of these emerging forces across economic, societal, and security domains. The findings underscore the transformative potential of AI, predicting significant shifts in employment patterns, regulatory challenges, and societal structures. Specifically, the study forecasts a high probability of AI-induced unemployment reaching 40–50%, alongside the rapid evolution of AI technologies, outpacing existing governance frameworks, which could exacerbate economic inequalities and societal fragmentation. Simultaneously, the study examines the critical role of geopolitical developments, identifying increased nationalisation, the expansion of conflicts such as the Russia–Ukraine war, and the strategic manoeuvres of major powers like China and Israel as key factors that will shape the future global landscape. The research highlights a worrying lack of preparedness among governments and societies, with a 10% probability of their being equipped to manage the complex risks posed by these developments. This low level of readiness is further complicated by the short-term orientation prevalent in Western businesses, which prioritise immediate returns over long-term strategic planning, thereby undermining the capacity to respond effectively to these global challenges. The study calls for urgent, forward-looking policies and international cooperation to address the risks and opportunities associated with AI and geopolitical shifts. It emphasises the need for proactive governance, cross-sector collaboration, and robust regulatory frameworks to ensure that the benefits of technological and geopolitical advancements are harnessed without compromising global stability or societal well-being. As the world stands on the brink of unprecedented change, the findings of this study provide a crucial roadmap for navigating the uncertainties of the future. Full article

The potency of economic sanctions imposed on nations depends on demand and supply adjustment possibilities. Adverse GDP impacts will be maximal when import, export, production, distribution and finance are inflexible (universal non-substitution). This paper elaborates on these conditions and quantifies the maximum GDP loss that Western sanctions could have inflicted on Russia in 2022–2023. It reports the World Bank’s predictions, contrasts them with the results and draws inferences about the efficiency of Russia’s workably competitive markets. This paper shows that Russia’s economic system exhibits moderate universal substitutability and is less vulnerable to punitive discipline than Western policymakers suppose. The likelihood that economic sanctions will compel the Kremlin to restore Ukraine’s territorial integrity ceteris paribus is correspondingly low, even though war reduces Russia’s quality of existence. Western economic sanctions serve narrow geostrategic ends that are reconcilable with Pareto-efficient free trade and globalization, if precision-targeted, but as the Russo-Ukrainian war intensifies, an expanded array of novel and dubiously legal sanctions is degrading free trade, and spurring de-globalization and anti-Western coalitions. If this armed combat is prolonged, the goals of free trade and globalization could be set back for decades. Full article

Hepatitis delta virus (HDV) infection is the most severe form of viral hepatitis. Genotype 1 (HDV-1) is by far the most prevalent in Europe and globally, while HDV-5 predominates in Western Africa. Data about HDV seroprevalence in Portugal are scarce and genotyping studies have not been performed yet. We aimed to assess the seroprevalence and genotypes of HDV in a large cohort of HBsAg-positive patients followed in our Hepatology Unit between 2012 and 2022. The anti-HDV-positive patients were subjected to a cross-sectional analysis, including blood sample collection for HDV RNA testing and genotype determination. In the cohort of HBsAg-positive patients, 57.5% (480/835) were born in African countries and 665/835 (79.6%) had been screened for anti-HDV antibodies. The HDV seroprevalence obtained was 6.5% (43/665). Twenty-one patients (age 41.2 ± 9.9 years; 57.1% male) were included in further molecular analyses. HDV RNA was positive in 8/21 (38.0%) and classified as HDV-5 in 7 patients (6 from Guinea-Bissau and 1 from Cape Verde) and HDV-1 in 1 patient (from Ukraine). In the largest and most comprehensive study performed in Portugal regarding HDV epidemiology to date, seroprevalence and genotype distribution of HDV (with predominance of HDV-5) were strongly influenced by immigration, notably from African countries.

In this study, we analyzed the impact of government regulatory institutions on households’ natural gas use behavior and suggested that the conventional view of natural gas as a social utility is inappropriate. Pursuing this goal, we applied correlation analysis, regression analysis and the Granger causality test to assess the statistically significant impact of particular factors (environmental temperature, price and tariff on natural gas) on household gas consumption. Our study was based on the data on household gas consumption in 2019–2022. Ultimately, the lowest rate of influence was recorded by the Granger causality test (2.47%), compared to 6.88% in the test for the significance of the correlation coefficient and 9.23% in the t-test for the statistical significance of the regression coefficients. One has to note that the Granger causality test used in our study is considered the most sensitive model for analyzing economic data. Using statistical methods, we concluded that regulatory factors have a negligible impact on the volume of natural gas consumption by households. Our results suggest that the Ukrainian regulatory authorities should be cautious about using non-market mechanisms, such as price caps, in the energy sector. Full article
