Since the early 2000s, the European Union has increasingly prioritized policies aimed at combating social exclusion, with a focus on efficient fund allocation for social and sustainable cohesion objectives. Given the multidimensional nature of material deprivation, synthetic indicators are frequently employed in the literature to measure this phenomenon. However, these indicators often lack suitability for temporal analysis, which is crucial for understanding the persistence of disadvantaged statuses over time and the effectiveness of national and international policies. This article offers an innovative examination of the trends in material deprivation among European Union Member States during the period of 2005–2022. It provides a structured reconstruction of the phenomenon at the NUTS-1 level, within the context of the major economic and health crises that have characterized the 21st century. This study’s key innovation lies in the creation of a temporal index of material deprivation, employing the AMPI method, which incorporates a partially compensatory aggregative synthesis and allows for the monitoring of the phenomenon over time against a baseline year. This novel approach ensures the capability to analyze the evolution of material deprivation over time and across regions, with 2005 as the reference year. The findings reveal a general improvement in material deprivation levels compared to 2005, despite deteriorating conditions in the Mediterranean and Baltic regions. By maintaining 2005 as the reference year, this index facilitates the ongoing monitoring of the impacts of COVID-19 and the effects of national recovery policies, as well as the resilient and sustainable social policies promoted by the RecoverEU fund.

Residential energy storage systems offer significant potential for price arbitrage by capitalizing on fluctuations in electricity prices throughout the day. This study investigates the potential revenue from optimal battery scheduling for residential storage in different north-western European electricity price zones during 2023. Using Nord Pool day-ahead prices, we applied an optimization model to determine the revenue for two types of batteries: 5 kW/10 kWh and 10 kW/10 kWh. The analysis considered battery capacity, charging and discharging efficiency, and maximum charge/discharge rates. Our results show notable variations in potential revenue across different regions, with the Baltic states demonstrating the highest revenue potential. The findings indicate that while 10 kW batteries can generate higher total revenue, 5 kW batteries are more efficient in terms of revenue per cycle. These regional disparities underscore the need for targeted incentives and policies to enhance the economic viability of residential energy storage. The research results provide valuable insights into optimizing residential battery storage for price arbitrage, offering guidance for consumers, policymakers, and energy providers to maximize economic benefits in various electricity markets.

In the Baltic States and Belarus, the Middle Devonian period is characterised by an abundant fossil record of invertebrates such as scolecodonts, brachiopods, ostracods, trilobites, bivalves, crinoids, gastropods, and tentaculites. On the other hand, there was limited diversity in the conodont and other vertebrate fauna. In this study, we introduce a newly refined ichthyofaunal assemblage from the Eifelian and Givetian epochs from the present-day regions of Belarus and Lithuania. The isolated scales of Cheirolepis are identified as C. gaugeri, C. cf. gaugeri, C. aleshkai, C. cf. aleshkai, and Cheirolepis sp., while Orvikuina is represented by the isolated scales of O. vardiaensis and Orvikuina sp. The histological analyses for the scales of Orvikuina are provided here. Moreover, Orvikuina and Cheirolepis taxa are now recognised to be widely distributed throughout the Baltic States, especially Lithuania and Belarus, as a result of these findings. Thus, this ichthyofaunal data markedly improved the biostratigraphic correlation within the study region and expanded the paleogeographic distribution of these taxa during the Eifelian and Givetian time in Laurasia.

This article presents the economic viability of using 10 m wind turbines in households with financial support from the government. The aim of this study was to indicate whether and how state subsidies affect the efficiency and estimated payback periods of wind energy investments for individual households. The research conducted thus far has focused on the analysis of effectiveness, feasibility, and economic profitability, but it has not taken into account government support for the investment readiness of households, which constitutes a research gap in the literature and economic practice. In addition, this study analyzed a new program that is scheduled to come into force this year. The analysis used the Homer Pro software (ver. x64) module, and simulations were performed for three locations in Poland. Due to differences in the location of wind zones, as well as the location of two locations on the Baltic Sea, an additional factor characterizing the studied voivodeships was introduced. Government support may therefore constitute a mechanism for correcting the geographical location and local wind potential. It has been shown that financial support significantly accelerates the payback period, even in locations with weaker wind potential. Complementary and substitutive possibilities for renewable energy sources, such as sun and wind, were indicated. The conclusions from this research can be used by decision makers and individual households to take advantage of government support to shorten the return on investment in wind energy and the validity of this support.

The response of benthic habitats and organisms to bottom-contact fishing intensity is investigated in marine protected areas (MPAs) of the German EEZ in the North and Baltic Seas. We examined the current state of macrofauna biodiversity in 2020–2022. Comparative analysis for macrofauna (in- and epifauna) inhabiting nine Natura 2000 MPAs constitutes a baseline to assess the effects of bottom-contact fishing exclusion in the future. Aspects of spatial and temporal variability are briefly summarized and discussed. We provide a species list for each region, including 481 taxa, of which 79 were found in both regions, 183 only in the North Sea, and 219 only in the Baltic Sea. The Baltic Sea dataset surprisingly included higher numbers of taxa and revealed more Red List species. The share of major taxonomic groups (polychaetes, bivalves and amphipods) in species richness showed peculiar commonalities between the two regions. In the North Sea, multivariate analysis of community structure revealed significantly higher within-similarity and stronger separation between the considered MPAs compared to the Baltic MPAs. Salinity, temperature and sediment fractions of sand were responsible for over 60% of the variation in the North Sea macrofauna occurrence data. Salinity, mud fraction and bottom-contact fishing were the most important drivers in the Baltic Sea and, together with other considered environmental drivers, were responsible for 53% of the variation. This study identifies aspects of macrofauna occurrence that may be used to assess (causes of) future changes. Full article

In the event of an outbreak of African swine fever (ASF) in pig farms, the European Union (EU) legislation requires the establishment of a restricted zone, consisting of a protection zone with a radius of at least 3 km and a surveillance zone with a radius of at least 10 km around the outbreak. The main purpose of the restricted zone is to stop the spread of the disease by detecting further outbreaks. We evaluated the effectiveness and necessity of the restricted zone in the Baltic States by looking at how many secondary outbreaks were detected inside and outside the protection and surveillance zones and by what means. Secondary outbreaks are outbreaks with an epidemiological link to a primary outbreak while a primary outbreak is an outbreak that is not epidemiologically linked to any previous outbreak. From 2014 to 2023, a total of 272 outbreaks in domestic pigs were confirmed, where 263 (96.7%) were primary outbreaks and 9 (3.3%) were secondary outbreaks. Eight of the secondary outbreaks were detected by epidemiological enquiry and one by passive surveillance. Epidemiological enquiries are legally required investigations on an outbreak farm to find out when and how the virus entered the farm and to obtain information on contact farms where the ASF virus may have been spread. Of the eight secondary outbreaks detected by epidemiological investigations, six were within the protection zone, one was within the surveillance zone and one outside the restricted zone. Epidemiological investigations were therefore the most effective means of detecting secondary outbreaks, whether inside or outside the restricted zones, while active surveillance was not effective. Active surveillance are legally prescribed activities carried out by the competent authorities in the restricted zones. Furthermore, as ASF is no longer a rare and exotic disease in the EU, it could be listed as a “Category B” disease, which in turn would allow for more flexibility and “tailor-made” control measures, e.g., regarding the size of the restricted zone.

The research question in this paper concerns elements of nature, such as earth, water, fire, and air, as they have a dual meaning, indicating both hazard and heritage. The relationship of cities with blue–green infrastructure is an example of this. Cities might be surrounded by either water or forest, though the latter has been less investigated as a nature-based solution for climate change adaptation. The connection between water and architecture can also be seen in the seafront type of architectural design, in the architecture of harbours, port facilities, aquariums or thermal baths. This paper aims to present a comprehensive analysis of all of these various architecture programs that were carried out during the first half of the twentieth century. Although the styles of Art Nouveau and Interwar were widely spread, otherness in regional geographical locations drew lessons from the vernacular architecture. Inspiration was drawn mainly from southern Europe in the Cycladic islands for the interwar/international style and towards the east and centre of the continent in Romania and Hungary and up to the north in the Baltic states for the national romantic art nouveau style. A local seismic culture is prevalent in areas that are affected by earthquakes. In the context of the geological conditions related to water and earthquake hazard, the anthropic reshaping of rivers and canals (and alluvial soil deposits) generates liquefaction vulnerability. Significant also is the way in which the urban wildland interface shapes the relationship between wild green space and cities. Urban protected nature parks and urban forests contribute to wellbeing but are also vulnerable to wildfire. This research attempts to find equivalents to the local seismic culture in cases of climate change-induced hazards, such as floods and wildfires, in Romania, Italy and Portugal. As part of the project presented for the case study featured in this paper, significant documentation was achieved through literature reviews and field trips. For the latter, walkscape methodology was used, which was also useful for the first round of results and the mapping required to indicate earthquake hazards near water locations in Bucharest, Romania.

Mycoplasma spp. pathogens frequently cause chronic and acute diseases in cats. The aim of the present study was to investigate the presence and genetic diversity of Mycoplasma spp. in cats and their ectoparasites using PCR and sequence analysis of the 16S rRNA gene. Blood samples were collected from 541 domestic and stray cats in Lithuania. Ectoparasites (153 fleas and 321 ticks) were collected from owned domestic cats that live both outdoors and indoors. Mycoplasma spp. were detected in 7.2% of cat blood samples and 4.4% of Ctenocephalides felis fleas. The sequence analysis revealed the presence of Mycoplasma haemofelis in 1.1% of cats and ‘Candidatus Mycoplasma haematominutum’ in 4.8% of cats. Ct. felis fleas harboured M. haemofelis. To the best of the authors’ knowledge, this is the first report on the prevalence and molecular characterisation of Mycoplasma bacteria in cats in Lithuania and cat fleas in the Baltic States.

Chemical pollution affects the health of marine biota, key functions of the ecosystem, and endangers its biodiversity. The current environmental monitoring and assessment approach is based on chemical and ecological measurements, while the linkage between them, biological effects at the individual level, has been largely neglected. It is currently well acknowledged that the monitoring of chemical concentrations alone is not sufficient to protect populations; it considers only a tiny number of substances, while myriad others are left unnoticed. In addition, the hazards related to contaminant mixtures remain undetected. Biological effects of contaminants can be detected and measured at different levels of biological organization, i.e., from the molecular/biochemical level up to changes in populations and communities. In Baltic Sea monitoring programs, the few observations on the effects of contaminants have, for decades, mostly been made at only the higher biological organization levels, applying reproduction success parameters in top predators such as raptor birds and seals as indicators. However, recording early warning signals of contaminant exposure and effects on the health of individuals at lower biological levels makes it possible to anticipate and prevent damage at the higher levels. Moreover, it is also crucial to monitor effects at lower levels of the marine food web. The so-called biomarkers focus on changes in various biological functions and include parameters related to the detoxification of xenobiotics, oxidative stress, neurotoxicity, geno- and cytotoxicity and reproductive disorders, among others. Research on biomarkers aiming at improving their use in monitoring and assessing the contamination status of marine areas has been intensive during recent decades, although the implementation of the methods to monitoring programmes has been slow. Here, the current state of biological effects monitoring using biomarkers, as well as selected case studies in the Baltic Sea, are presented, followed by recommendations on their application in this sea area.

Due to rising surface air temperatures, river ice is shrinking dramatically in the Northern Hemisphere. Ice cover during the cold season causes fundamental changes in river ecosystems and has important implications for nearby communities and industries. Changes caused by climate warming, therefore, affect the sustainability of key resources, livelihoods, and traditional practices. Thus far, too little attention has been paid to research into the phenomenon of river ice in the Baltic States. Since the observational data of the last sixty years are currently available, we took advantage of the unique opportunity to assess ice regime changes in the gauged rivers by comparing two climatological standard normals. By applying statistical methods (Mann–Kendall, Pettitt, SNHT, Buishand, von Neumann, and Wilcoxon rank sum tests), this study determined drastic changes in ice phenology parameters (freeze-up date, ice break-up date, and ice cover duration) of Lithuanian rivers in the last thirty-year period. The dependence of the selected parameters on local climatic factors and large-scale atmospheric circulation patterns was identified. It was established that the sum of negative air temperatures, as well as the North Atlantic Oscillation, East Atlantic, and Arctic Oscillation indices, have the greatest influence on the ice regime of Lithuanian rivers.

The Baltic states—Estonia, Latvia, and Lithuania—are situated on the eastern coast of the Baltic Sea between Russia and the Scandinavian countries. This region is characterized by diverse landscapes and numerous bodies of water, including lakes, peat bogs, and marshes, which serve as natural habitats for aquatic invertebrates, including leeches. Despite the rare and uncertain taxonomic status of leech species in the area, research in the Baltic region has been inadequate. Therefore, this study aims to examine the composition of leech species in the Baltic countries, drawing on both past and current research. The study also seeks to assess the status of Hirudo medicinalis in the Baltic region and discuss the rare, questionable, and potentially present leech species in the Baltic states. A scoping review method was employed, surveying published references, books, and databases. In total, the study found records of 21 leech species in Estonia, 15 in Latvia, and 26 in Lithuania, belonging to the families Glossiphoniidae, Erpobdellidae, Hirudinidae, Haemopidae, and Piscicolidae. Hirudo medicinalis L. is distributed throughout all Baltic countries, but the most recent records on their location are only available for Estonia. The data on a few Piscicolidae species is questionable and requires verification, but further research on Piscicolid leeches can potentially lead to the discovery of rare species. Full article

Features of internationalization, such as trade, foreign direct investments, and international migration, are crucial for understanding the economic developments of small and open economies. However, studying internationalization at the country level may obscure significant heterogeneity in its relationship with economic growth and other economic and social outcomes. Regional accounts provide insights into the geography of internationalization, but collections of such disaggregated statistics are rarely provided by statistical bureaus. The purpose of this paper is twofold. First, we demonstrate how regional account data, including internationalization indicators, can be constructed to obtain consistent and homogeneous regional-level series using a combination of micro and macro data sources. Second, our aim is to foster spatial research on internationalization and the spatial economy in the Baltics by providing comprehensive data collection of socio-economic variables at the NUTS 3 regional level over time. This collection encompasses trade, FDI, and migration, enabling the study of internationalization and other features of the Baltic economy. We present a series of key features, revealing noticeable correlation patterns between regional development and internationalization. Full article

Asphalt pavement, a component of transport infrastructure, deteriorates under the influence of destructive factors. The damages which have occurred during its period of use are repaired and the asphalt pavement is recycled when its further rehabilitation is economically and technically irrational. The material from the asphalt pavement layer that has reached its limit state is milled out or broken and crushed and then is repeatedly used in the production of hot-mix asphalt (HMA) or warm-mix asphalt (WMA) mixtures. In this paper, the dynamics of the percentage recycling ratio (RR) of old asphalt pavement material was investigated. RR represents the quantity of reclaimed asphalt pavement (RAP) used in the production of HMA and WMA mixtures in Europe and the USA, divided by the total amount of RAP prepared in the country. Factors and goals affecting it are analyzed. An original system of 10 criteria that increase the RR country has been created. Decision makers do not know which factors have the maximum influence in increasing the use of RAP and this should go in connection with environmental pollution reduction and achieving economic utility. By applying different multiple-criteria decision-making (MCDM) methods and using the importance given to these criteria by 14 experts, the normalized subjective weights of the criteria were determined. Analytic hierarchy process (AHP), rank correlation, average rank transformation into weight—linear (ARTIW-L) and non-linear (ARTIW-N), and direct percentage weight (DPW) methods were used in the study. The results show that the RAP recycle rate is close to 100% in countries with a sustainable economic background. In the Baltic countries, it is mostly increased by the adequacy of regulatory documents, the strategy promoting asphalt recycling in the country, and the homogeneity and classifying of RAP. The number and capacity of RAP stocks, the number and productivity of asphalt milling equipment and the wear and tear of the asphalt pavement have the least influence on the increase in RR. The opinions of experts in assessing the significance of all criteria are consistent. The averages of the weights of criteria determined by four MCDM methods (AHP, ARTIW-L, ARTIW-N, DPW) made it possible to obtain more reliable results. These results can be used to make strategic decisions and to create a plan of practical actions to increase the RAP recycling rate in the developing countries. Full article

Gogland Island, located in the Gulf of Finland in the Baltic Sea, was densely populated in the past but has been nearly abandoned since the Second World War. The self-restoration of wildlife takes place there. Recent research on the island aimed to evaluate the conservation value of this process. It was expected that the island would demonstrate a standard for the perfect state of protected areas of the boreal zone of Europe. The island has been overgrown with forests; open areas occupy insignificant parts and tend to shrink. Picturesque landscapes have been formed, but the conservation value of these areas are questionable as the biodiversity is rather low there. They contain “empty forest” that is partly impassable. The island demonstrates that to achieve the maximum effect for biodiversity conservation, the abandonment of land without any management would be insufficient. The fate of the island partly supports the concept of Pleistocene rewilding: a mosaic of forests and meadows, maintained by ungulates, should be considered a normal state of environments. Full article
