The scope of this paper is the interpretation of sustainability through the university as a traditionally recognized, value-based institution of knowledge, based on the example of Central and Eastern Europe, Hungary. Its aim is to interpret sustainability from different aspects, using the example of Central and Eastern Europe, including Hungary. For this purpose, the paper reviews the development policy directions of the past period and institutional realizations through public databases. The results of the research show that there are different dynamics and focus in terms of resources and development implementations. From the point of view of sustainability, it represents that the use of resources with different dynamics and focus is a challenge for the institutions. [ABSTRACT FROM AUTHOR]

Under the pressure of global carbon neutrality, it is necessary to study the characteristics of carbon emissions and the trend of "carbon peaking" in countries along the "Belt and Road." Because most of these countries have not yet reached their peak carbon emissions, they still have great potential for growth, and peak carbon emissions are a prerequisite for carbon neutrality. This paper divides the countries along the Belt and Road into 9 country groups according to the level of economic development and industrial structure. Based on the carbon emission panel data of countries along the "Belt and Road" from 1970 to 2018 and environmental Kuznets curve (EKC) theory, a panel model was established for each country group for research. This paper analyzes the characteristics of carbon emissions and the trend of "carbon peaking" in these countries and analyzes the economic growth and carbon emissions in combination with the Tapio decoupling model. The decoupling relationship changes on the time scale as a supplement. The results show that in the study area, some countries have completely passed the "carbon peak." The reasons for this are as follows: first, the carbon peak is achieved through industrial upgrading; second, the "carbon peak" is caused by the drastic changes in Eastern Europe and the disintegration of the Soviet Union and deindustrialization; and third, the carbon peak is caused by poverty and population growth. Most of the remaining countries have not yet achieved the carbon peak. Among them, some countries represented by the Middle East are highly coupled with their economic development and carbon emissions. Middle-income and high-industrial-dependence countries are in the transitional period in terms of the carbon peak. Low-income and medium- and high-industrial-dependence countries are currently still in the stage of barbaric development. From the research on the decoupling situation, the relationship between the economic growth of countries along the "Belt and Road" and their carbon emissions has been improving in recent decades, and it is expected that a more ideal state of decoupling will be achieved in the future.

Detailed palaeogeographical studies of the accumulative fan in the Serteyka River valley in W Russia and underlying biogenic deposits were carried out. The base of a representative core of biogenic sediments in the distal zone is dated to 1291 BC, while its top to 1631 AD. In this paper, palynological, plant macrofossils, Chironomide and Cladocera, geochemical, geochronological and sedimentological analysis were performed. Four phases of biogenic deposition were distinguished by pollen and geochemical analyses. Two of them coincide with the climatic fluctuation during Medieval Climate Anomaly and Little Ice Age. During the formation of the fan, overbank deposits were accumulated also, indicating numerous and intense floods, which are in line with the trend observed for other sites in this region. The accumulative fan is formed by lower, middle and upper deluvia and agricultural diamicton in its top. All units have specific sedimentological and geochemical features as well as low admixture of plant macrofossils. The beginning of the formation of this relief form dates back to the second half of the 17th century AD, and the end of the accumulation falls on the second half of the 18th century AD. Our work suggests that natural conditions had an impact on the formation and development of studied accumulative fan, however, the decisive factor causing the intensification of the slope processes were related with deforestation resulted from strong human impact, which was marked in palynological and macrofossils analyses (e.g. increase in the contribution of plants macrofossils related to agriculture).

The impacts of climate change are unevenly distributed across territories. Less is known about the potential effects of climate policies aimed at mitigating the negative consequences of climate change while transitioning economies towards low-carbon standards. This paper presents an analytical framework for identifying and assessing the regional impacts of the green transition. We develop a Regional Green Transition Vulnerability Index, a composite measure of the regional vulnerability of European regions to the socio-economic reconfigurations prompted by the green transition. The index brings to light strong regional variations in vulnerability, with less developed, peri-urban and rural regions in Southern and Eastern Europe more exposed to the foreseeable changes brought about by the green transition. We also draw attention to the potential rise of pockets of growing 'green' discontent, especially if the green transition contributes, as is likely to be the case, to leaving already left-behind regions further behind.

Considering the negative effect of anthropological activities on climate in recent decades, all countries entailed a universal commitment to fight against climate change by boosting innovation and introducing new technologies. In this context, our paper aimed to investigate the impact of innovation input in terms of research and development (R&D) costs and technology expressed as technical equipment and machinery (TEM) on the reported greenhouse gas (GHG) emissions in chemical industry companies in five Central and Eastern European countries. This study employed a panel regression model with fixed effects and covered data from 2015 to 2020. The empirical results emphasize a negative relationship between R&D costs and GHG emissions, indicating the companies' commitment to developing innovative solutions that contribute to lower destructive emissions. Additionally, the findings related to the influence of TEM on GHG emissions reveal a positive impact, highlighting the need to improve manufacturing technologies. The practical implications of our findings can be meaningful for both policymakers and businesses operating in the chemical industry in developing countries. Policymakers should offer financial incentives to support research and investments in clean technologies, while businesses should prioritise such investments to mitigate GHG emissions.

Simple Summary: During the last glaciation, the nature of the northern hemisphere of the Earth underwent significant changes. Nonetheless, it underwent no less serious changes after the melting of the glacier, when, under the conditions of climate mitigation, the gradual formation of modern landscapes began in the spaces freed from ice. This study is devoted to the reconstruction of the post-glacial environment in one of the regions of Eastern Europe, in the south-eastern part of the Baltics. The uniquely preserved deposits of one of the post-glacial basins discovered here made it possible to reconstruct in detail the changes in climate, vegetation, and aquatic organisms in the time interval of 14–13.4 thousand years ago. The study revealed that during this period there were short-lasting climate fluctuations (warmings and coolings), which caused repeated changes in all components of the local nature. The results of the study contribute to understanding the complex processes of planetary climate formation, as well as the impact of climate on nature both at local and global levels, which is necessary not only for understanding the past, but also for predicting the future of all living organisms on the planet. This paper presents the results of a study on the Kulikovo section (south-eastern Baltic Sea coast), a sediment sequence exposing deposits of a post-glacial basin that existed along the edge of the glacier in the Late Pleistocene. The research was targeted at the reconstruction of the dynamics of the local environmental systems in response to climatic oscillations of the Lateglacial (the Older Dryas—first half of the Allerød). The evolution of the local biotic components on the territories of the Baltic region after the ice retreat is still poorly understood. Data from geochronological, lithological, diatom, algo-zoological and palynological analyses provide a reconstruction of local aquatic and terrestrial biocenoses and their response to short-term warmings and coolings that took place 14,000–13,400 cal yr BP. This study has demonstrated that, during the Older Dryas and first part of the Allerød (GI-1d and GI-1c), the aquatic and terrestrial environment of the Kulikovo basin underwent several changes, resulting in eight stages of the basin evolution, most probably related to the short-term climatic fluctuations that could have had a duration of several decades. The data obtained in this study have revealed the fairly dynamic and complex evolution of the pioneer landscapes, as indicated by the changes in the hydrological regime of the area and by the traced successions of plant communities from the pioneer swampy vegetation to park and real forests towards the middle of the Allerød.

The recent climate change scenarios show significant increases in temperature and extreme drought events in Southern and Eastern Europe by the end of the 21st century, which will have a serious impact on forest growth and adaptation, and important consequences for forest management. The system of provenance regions, according to the OECD Scheme and EU Directive, was thought to encourage the use of the local seed sources, under the concept 'local is the best'. However, climate is changing faster than some species or populations can adapt or migrate, which raises some uncertainties with respect to the future performance of local populations. In Romania, as in other countries, the delimitation of provenance regions is based on geographical, ecological and vegetation criteria. The aim of this study is to evaluate: (1) the climate change that has occurred at the level of the provenance regions; (2) which regions will be most vulnerable to climate change; (3) which forest types will be the most vulnerable in a certain region; and (4) changes in the climatic envelope of forest species. Several climatic parameters and an ecoclimatic indices have been calculated and analyzed at the level of provenance regions, subregions and ecological sectors (forest types) in Romania, during the period 1951–2020. The results highlight a general shift towards warmer and drier conditions in the last 30 years, the mean annual temperature increasing with 0.3–1.1 °C across the provenance subregions. The De Martonne aridity index for the vegetation season shows that 86% of the ecological sectors fell into the arid and semiarid categories, which indicates a very high degree of vulnerability for forest species. On the Lang rainfall index, forest steppe climatic conditions occurred in all pure or mixed pedunculate oak forests, thermophile oak species, meadow forests, poplar and willow, Turkey oak and Hungarian oak forests. The Ellenberg coefficient highlights that the warming process is more evident along the altitude and the degree of vulnerability increase at lower altitude or at the edge of species distribution. The climate envelopes of many forest species have already shifted to another ecosystem's climate. This paper presents the importance of re-delineation the provenance regions for the production and deployment of forest reproductive materials according to the climate change occurred in the last decades, as a fundamental tool for an adaptive forest management.

The study of the impact of climate change on the fish fauna and fisheries management is a relatively young field of scientific research which has yielded very few analytical studies in the Central and Eastern European countries. This paper is the first attempt to examine the impact of this change on lake fisheries management, made based on an extensive and representative survey addressed at managers and owners of the entities authorised to use these waters for fishing and angling purposes. The conducted analyses enabled the determination of their opinions on the issues of climate change impact on the fish, selected hydrological and biological lake parameters, the possibility of use of fishing gear and its efficiency, the length of angling season, the amount of individual fish species caught by anglers and fishermen, and positive phenomena relating to climate change. Of all the phenomena arising from this change and perceived by the respondents surveyed, the growing population of the great cormorant (Phalacrocorax carbo (L.)), which is exerting increasing pressure on the fishery resources, and conducive to this change, is definitely at the head of the list. As regards the fish species, the pike (Esox lucius L.) is the most vulnerable to this change. The presented results prove that the managers under the study are aware of the ongoing changes and their impact on lake fisheries management, and of the challenges that they will have to face as early as in the coming decades of the 21st century.

Populist parties are on the rise. But what happens when they are in government? In order to grasp the effect of populist parties in government systematically, the paper includes all 28 EU member states in an analysis which estimates the effect of populist parties in power on the increase of greenhouse gas (GHG) emissions. The results show that depending on their ideological orientation populist government participation is clearly associated with increasing GHG emissions. Furthermore, the analysis shows that the effect is quick. This is above all true for right-wing populist parties in government. Furthermore, the analysis shows that populist parties have different impacts in various regions of the EU. While right-wing populist governments are associated with an increase of GHG emissions in North Western and Eastern Europe, left-wing populist governments in Southern Europe have the opposite effect.

This paper focuses on a grassroots community movement addressing climate change: the transnational Transition (Towns) movement. While this movement has mainly spread to Anglophone countries, it is almost entirely absent from Eastern Europe and the Czech Republic in particular. The aim of this paper is to explain why the Transition movement--a grassroots community initiative--has not been successfully adopted in the post-socialist Czech Republic, and why the issue of climate change has not become an important frame for the local permaculture movement which introduced the idea of Transition to the country. The paper presents an analysis of ideological frames and framing processes of the local movement. Reasons identified for the movement's absence from the Czech Republic include the fact that it was largely overshadowed by the broader post-socialist transformation in Eastern Europe, that there was little public awareness of climate change and no real culture of community organising in the post-socialist period, and that a strong climate scepticism was promoted by Czech political elites. Other reasons relate to the ideological frames of the local permaculture movement, which is centred more on prognostic and mobilising frames, combined with a positive agenda and an emphasis on practical activities, and revolves around individualised strategies and frames in which permaculture and a nature religion (Anastasian spirituality) are linked to the concept of a 'family homestead'. The research draws on in-depth interviews with permaculture practitioners, media analysis, the study of documents, and participant observation. [ABSTRACT FROM AUTHOR]

This paper examines which factors influence women's descriptive representation in state delegations to the international climate change negotiations. Due to the gendered nature of climate change as an issue, it is important to study the representation of women in the negotiations and to examine its normative and functional implications. Theoretically, I propose to look at institutional, socioeconomic, and cultural factors as potential explanations for the variation in the proportion of women in state delegations across countries. I examine this variation by drawing on a dataset containing all member state delegations to the United Nations Framework Convention on Climate Change negotiations from 1995 to 2011. The theoretical arguments are then tested on these data using a fractional probit model. This is the first comparative study of women's descriptive representation in international environmental negotiations. It contributes to our understanding of the variation in women's representation both over time and across countries. In particular, I find that women's representation is higher in countries that enjoy a higher level of development and a higher degree of political gender equality. The effects of other institutional and socioeconomic factors such as the level of democracy or gender-equal development remain statistically insignificant. Cultural factors measured by regional proxies show that Eastern Europe and Latin America are positively and the Middle East negatively linked with women's descriptive representation in delegations.

Increased fire activity, related both to human activities and to climate change, necessitates effective fire prevention and suppression strategies. The main purpose of this paper is to model and map fire suppression difficulty using common approaches in three different ecosystems in Eastern Europe by employing very high-resolution satellite imagery and landscape fire behaviour modelling. The integrated approach could allow fire managers to organize prevention and management of firefighting activities more efficiently by implementing both simple and easy-to-use risk and operational fire suppression difficulty indices. The development of cross-border common methodological approaches could foster cooperation between national authorities that would also maximize the efficiency of firefighting procedures.

Eastern Europe today is confronted with an unavoidable problem - the multifamily apartment building stock is deteriorating but apartment owners do not have sufficient access to resources be they organizational, financial, technical or legal. In addition, destructive myths have grown about the Soviet era buildings despite their continued resilience or the ex- GDR experience in the 90s with the same buildings. Further, without resources, decision making in residential apartments is seen as a major obstacle and used as an explanation why renovation has not taken place in Latvia. This is important not only in the context of a potential housing crisis but also because the renovation of the apartment buildings is an effective solution to significantly reduce the energy consumption and greenhouse gas emissions. It has a proven potential to effectively finance the long term renovation of these buildings. This paper summarizes the first findings of a comprehensive and in-depth study of apartment buildings, their owners and the processes relating to renovation, combining social and environmental engineering research methods. It seeks to understand how owners of multi-family buildings in Eastern Europe understand their buildings and then to answer two questions - how to motivate owners to renovate their homes and increase energy efficiency and what business models should be used to implement economically viable and high quality projects.

Large Multiscenarios Multimodel Ensembles (MMEs) of regional climate model (RCM) experiments driven by Global Climate Models (GCM) are made available worldwide, and aim at providing robust estimates of climate changes and associated uncertainties. Due to many missing combinations of emission scenarios and climate models leading to sparse Scenario-GCM-RCM matrices, these large ensembles are however very unbalanced, which makes uncertainty analyses impossible with standard approaches. In this paper, the uncertainty assessment is carried out by applying an advanced statistical approach, called QUALYPSO, to a very large ensemble of 87 EURO-CORDEX climate projections, the largest ensemble ever produced for regional projections in Europe. This analysis provides i) the most up-to-date and balanced estimates of mean changes for near-surface temperature and precipitation in Europe, ii) the total uncertainty of projections and its partition as a function of time, and iii) the list of the most important contributors to the model uncertainty. For changes of total precipitation and mean temperature in winter (DJF) and summer (JJA), the uncertainty due to RCMs can be as large as the uncertainty due to GCMs at the end of the century (2071-2099). Both uncertainty sources are mainly due to a small number of individual models clearly identified. Due to the highly unbalanced character of the MME, mean estimated changes can drastically differ from standard average estimates based on the raw ensemble of opportunity. For the RCP4.5 emission scenario in Central-Eastern Europe for instance, the difference between balanced and direct estimates are up to 0.8°C for summer temperature changes and up to 20% for summer precipitation changes at the end of the century.

Increasing temperatures and changing precipitation patterns impact plants biotic constrainers worldwide affecting host-pathogen relationship depending on geographical and temporal distribution of inoculum amount and cultivars susceptibility. Leaf rust of rye, which is caused by the obligate biotrophic basidiomycete Puccinia recondite f. sp. secalis (Roberge ex. Desmaz) has become one of the most important limiting factors for rye production in Central and Eastern Europe. During 2019-2020 growing season, a plant-pathogen interaction profile was observed on four rye genotypes in a randomized complete block design with three replications in dry area from Research and Development Station for Plant Culture on Sands Dăbuleni in south of Romania. Adult plant partial resistance was assessed through host response and epidemiological parameters as final rust severity (FRS), area under the disease progress curve (AUDPC), relative area under the disease progress curve (rAUDPC), coefficient of infection (CI) and infection rate (IR). The response of rye genotypes to leaf rust included different variation in resistance reaction ranging from moderately resistant (Serafino, Bintto), moderately susceptible (Inspector) and very susceptible (Suceveana). A negative and highly significant correlation of AUDPC with grain yield (r =-0.9194***) was found during 2019-2020 cropping season. [ABSTRACT FROM AUTHOR]

According to the objectives of the European Union concerning the climate changes, Member States should take all the necessary measures in order to reduce the greenhouse gas emissions. The aim of this study is to identify the causality relations between greenhouse gases emissions, added value from agriculture, renewable energy consumption, and economic growth based on a panel consisting of 11 states from the Central and Eastern Europe (CEECs) in the period between 2000 and 2017. The Autoregressive Distributed Lag (ARDL) method was used to estimate the long-term relationships among the variables. Also a Granger causality test based on the ARDL - Error Correction Model (ECM) and a Pairwise Granger causality test were used to identify the causality relationship and to detect the direction of causality among the variables. The results obtained reveal, in the long term, two bidirectional relationships between agriculture and economic growth and two unidirectional relationships from agriculture to greenhouse gas emissions and renewable energy. In the short term, four unidirectional relationships were found from agriculture to all the variables in the model and one unidirectional relationship from renewable energy to greenhouse gas emissions.

The paper reports on a study of extremely cool summers (ECS), a rare but significant phenomenon responsible for various adverse economic effects. These include, in particular, effects on agriculture and the tourist industry. The seasons, their spatial extent and individual characteristics were identified in Central and Eastern Europe. The research was based on average seasonal air temperatures (June to August) and the numbers of days with maximum temperatures >25, 30 and 35 °C and minimum temperatures >20 °C, as recorded at 59 weather stations during the period 1951-2010. An ECS was defined as having an average temperature at least 2 standard deviations (t ≤ t − 2σ) lower than the average at a given station during the study period. ECS occurred at only 34 of the 59 stations (58 % of all stations), one or two per station, mainly in the northern part of the study area. Six such seasons were recorded by at least 5 % of all stations in 1962, 1969, 1976, 1978, 1984 and 1994. The average temperature of an ECS was typically 2-3 °C lower than the long-term average. While some ECSs included an extremely cool month, most such seasons (58 %) were defined by low temperatures persisting for long periods in all summer months. [ABSTRACT FROM AUTHOR]

This paper joins the growing scholarly concern for the sharpening of social and environmental inequalities in European cities, particularly those generated in Eastern Europe by evictions of poor Roma from inner-city areas and by the invisibilization of their extreme conditions. We argue that these processes – evictions and invisibilizations – create a heightened vulnerability to climate change impacts for these individuals. The paper uses secondary survey data on compact Roma groups in Romania and analyses qualitative and cartographic information collected by the authors (2019) in two mid-sized cities in Romania to flesh out the particular slum ecologies that emerge following evictions. The focus is also on the subtle processes of invisibilization that render displaced Roma vulnerable and rob them of the "right to the city" in terms of climate change adaptation. Our finding is that evicted Roma experience innumerable, "routine" weather-related impacts, such as floods, storms or cold. By exploring Roma's heightened exposure, sensitivity and reduced adaptive capacity, we show how these impacts increase their vulnerability to future extreme weather events. These findings are indicative of a broader process of fragmentation taking place in urban areas throughout Eastern Europe, which render invisible some very real barriers to climate change adaptation. • The evictions of poor Roma from two cities in Romania are explored. • These evictions create vulnerabilization to climate change impacts. • Evicted Roma face exposures, increased sensitivity and reduced adaptability. • These effects are invisibilized and preclude the adoption of adaptation measures.

Recent studies show an increase in the frequency of compound extremes in air temperature and precipitation in many parts of the world, especially under dry and hot conditions. Compound extremes have a significant impact on all spheres of human activity, such as health, agriculture, and energy. Features of atmospheric circulation are closely related to the occurrence of anomalies in air temperature and precipitation. The article analyzes the relationship of atmospheric circulation modes with compound extremes that have had the greatest impact on the Atlantic–European region over the territory of Eastern Europe over the past 60 years on extreme air temperature and precipitation. Combinations of extreme temperature and humidity conditions (indices)—cold-dry (CD), cold-wet (CW), warm-dry (WD) and warm-wet (WW)—were used as compound extremes. Indices of compound extremes were calculated according to the E-OBS reanalysis data. Estimates of the relationship between two time series were carried out using standard correlation and composite analyses, as well as cross wavelet analysis. Phase relationships and time intervals for different climatic indices were different. The period of most fluctuations in the indices of compound extremes was from 4 to 12 years and was observed during 1970–2000. The coherent fluctuations in the time series of the WD and WW indices and the North Atlantic oscillation (NAO) index occurred rather in phase, those in the time series of the CD and WD indices and the Arctic oscillation (AO) index occurred in antiphase, and those in the time series of the WD and WW indices and the Scandinavia pattern (SCAND) index occurred in antiphase. Statistically significant increase in the number of warm compound extremes was found for the northern parts of the study region in the winter season with positive NAO and AO phases.

The article examines the relationship between poverty and conflict. Violent conflicts will likely occur in developing countries or regions, such as Sub-Saharan Africa, Africa, Eastern Europe, or Southeast Asia. The main question is whether they are caused by extreme poverty, so there is a scarcity of resources that leads to violent conflicts, or whether there are enough resources. However, only a handful of people in that society can access the resources, which in the end, creates friction and conflict. The conflict has multifaceted dimensions; usually, there is no single cause of conflict. Instead, it involves many aspects, such as political, social, economic, cultural, and other conditions. Economic disparities, gender inequality, unequal distribution of power, power struggles within different societies, climate crises, ethical tensions, genocides, and many other reasons may serve as the causes of conflict. This article will analyze the two factors likely to cause conflict, greed and grievance. Greed and grievance are seen in the case studies presented in this article - the civil war in the aftermath of the Cold war period, which occurred in the 1990s. [ABSTRACT FROM AUTHOR]

In the modern world, when the problems of the environment are most acutely associated with climate change, amphibians are considered to be the most vulnerable group of anamniotes as an indicator of the state of wetlands. Along with a decrease of numbers among amphibians in Europe, nowadays newts especially suffer from the impact of invasive species, in particular predators such as the Chinese sleeper, Perccottus glenii. This predatory fish species has recently spread to areas of primary relevance for newt reproduction. This fish consumes eggs, larvae, and even adult newt individuals. Using an ecological niche approach and climate based species distribution models (SDM), we applied the coefficient of determination (R2) for comparing the level of similarity of the built SDM for the newts Triturus cristatus and Lissotriton vulgaris, and the Chinese sleeper. We show that by 2050, the level of climatic niche similarity for these native and invasive species will increase from 12% to 22% throughout Europe, and from 44% to 66% in Eastern Europe. This study highlights the expansion of the Chinese sleeper as a real threat to European biodiversity of wetlands in the near future, especially in their most northeastern distribution range.

This paper aims to develop the first differentiated (earlywood—EW, latewood—LW, and total ring width—RW) dendrochronological series for ash (Fraxinus excelsior L.) and oak (Quercus robur L.) trees from the Republic of Moldova, and to analyze their climatic response and their spatio-temporal stability. For this, 18 ash and 26 oak trees were cored from the Dobrușa protected area, Republic of Moldova, Eastern Europe, and new EW, LW, and RW chronologies were developed for ash and oak covering the last century. The obtained results showed that the RW and LW have a similar climatic response for both species, while EW is capturing interannual climate variations and has a different reaction. The analyses performed with monthly climatic data revealed a significant and negative correlation with the mean air temperature and a significant and positive correlation with precipitation and the Standardized Precipitation-Evapotranspiration Index (SPEI) for both ash and oak. The temperature during the vegetation period has a strong influence on all tree-ring components of ash, while for oak the strong correlation was found only for LW. The positive and significant correlation between LW and RW with precipitation for both species, suggests that ash and oak are sensitive to the hydrological component and the precipitation is the main tree growth-limiting factor. Despite the significant correlation with precipitation and temperature for the whole analyzed period, the 25-year moving correlation analyses show that they are not stable in time and can switch from positive to negative or vice versa, while the correlation with SPEI3 drought index, which is a integration of both climatic parameters, is stable in time. By employing the stability map analysis, we show that oak and ash tree ring components, from the eastern part of the Republic of Moldova, have a stable and significant correlation with SPEI3 and scPDSI drought indices from February (January) until September, over the eastern part of Europe.

Extreme heat is investigated in a series of high‐resolution time‐slice global simulations comparing the current and late‐21st century climates. An increase in climate‐relative extreme heat is found in the region surrounding the Black Sea. Similarities between the synoptic‐scale flows in current and future heat events combined with a decrease in future summer precipitation suggests that the increased future severity stems from strengthened land‐atmosphere feedbacks driven primarily by the changes in precipitation. The resulting intensification of heat events beyond the mean warming driven by climate change could generate significant future heat hazards in vulnerable regions. Given the continental cool bias in the present‐day simulations, the resulting estimates of future extreme heat are likely to be conservative. Plain Language Summary: Increases in extreme heat are a direct consequence of global warming. In some regions, however, the frequency and severity of heat waves can exceed what is expected given the rise in mean temperature alone. We examine this issue using data from a high‐resolution climate model run for 10 simulated summers under current and future (late 21st century) climate conditions. In the future simulations, extreme heat events, relative to the baseline of a much warmer climate, become more frequent and severe in a region surrounding the Black Sea. The weather patterns that lead to heat waves are very similar in the current and future climates. This similarity suggests that land‐atmosphere interactions during atmospheric heat waves amplify these events more in the future. Under warmer baseline conditions, the land dries out more rapidly during a heat event, reducing cooling from evaporation, and thus creating more severe and dangerous heat. Additionally, these model simulations are too cold over land areas, likely weakening the land‐atmosphere interactions so our projections of increased extreme heat are probably conservative. Key Points: Climate‐relative extreme heat events in certain regions are substantially amplified in a set of high‐resolution future climate simulationsThis regional amplification of extreme heat does not depend on changes in flow regimesResults suggest amplified heat may be due to stronger regional/local land surface feedbacks, resulting in faster drying in a warmer climate [ABSTRACT FROM AUTHOR]

Charting the long-term trends in European wheat and maize yields and harvested areas and the relation of yields to climatic and economic drivers, two profound spatial processes become apparent. One consequence of the relatively late modernization of Eastern Europe has been to shift the focus of grain production from West to East. The warming trend prevailing over the past decades in the summer and winter seasons has been accompanied by a South to North shift in the harvested areas. The combination of these two processes has meant that the north-eastern sector of the European grain chessboard has emerged as the main beneficiary. There, the relatively low sensitivity of cereals to climatic change plus high economic growth rates have been accompanied by the most dynamic increases in cereal yields on the continent. As a result, a modern version of the 3000 year-old grain distribution system of the Ancient World is being restored before our eyes. One noteworthy finding is that increasing January–March temperatures have had a significant positive impact on wheat yields from Northern to South-Eastern Europe, and this is, at least in part, compensating for the negative impact of summer warming.

The Clean Development Mechanism (CDM), a partnership tool founded under the Kyoto Protocol, grants potential opportunities to help developing countries achieve sustainable development. The present research examines the CDM projects in Eastern Europe (Moldova, Serbia, Bosnia and Herzegovina, Montenegro, and Albania). Although there were far fewer projects in this region than, for instance, China or India, it has some specific features that make it worth studying. Major findings are that most CDM projects in Eastern Europe involved a changing combination of two or more sources of financing, and the distribution of projects in the region was uneven. Moreover, although there was a small number of projects overall, they were all cost-effective, long-term and large-scale. The findings of the research call for improvements to be made to the governance of the CDM, by strengthening the international and national regulation of projects and by aggregating the scales of decision-making and actions so that real multi-scalar transnational governance — from the global level down to the local level — is implemented in a coherent manner. It is also recommended to carry out ex-post project evaluations, following which readjustments could be made. [ABSTRACT FROM AUTHOR]

The study analyzed the structure of water shortages in plant crops and the available groundwater resources that can be used to satisfy these needs. The research was carried out in Braniewo poviat, which can be considered representative of the conditions of Central and Eastern Europe. A clear upward trend in the temperature value was observed, which influenced the changes in the duration of thermal seasons and agricultural periods. It also increases the intensity of the evapotranspiration process, which results in the reduction of water resources. The presence of significant water shortages, especially in the cultivation of root crops, such as, for example, late potato or sugar beet, justifies the need to irrigate these plants. Due to unevenly distributed surface water resources, groundwater is used as a source of irrigation. It was found that in the case of many crops, the areas with the greatest water shortages were those with average or high abundance in available groundwater. When indicating the possibility of abstracting large amounts of groundwater for use in plant production in Braniewo poviat, one should consider the fact that, in the long term, their exploitation may cause negative environmental effects.

The sustainability of a territory is closely related to its resources. Due to climate change, the most precious natural resource, water, has been negatively affected by climatic conditions in terms of quantity and quality. CLIMAT datasets of 1 km2 spatial resolution were used and processed in the ArcGIS environment to generate maps of actual evapotranspiration, water availability, and effective precipitation for the periods of 1961–1990 (1990s), 2011–2040 (2020s), and 2041–2070 (2050s). The product is of paramount importance for the analysis of the actual situation in Europe indicating high water availability in the Alps Range, the Carpathians Mountains, Northern European countries, and the British Islands. On the other hand, low water availability has been evidenced in the Southern and Eastern European areas. For the future period (2050s), the monthly potential evapotranspiration is expected to increase by 30%. The climate models also show an increase in the actual evapotranspiration between past and future periods by 40%. The changes in water availability and effective precipitation between the past (1990s) and future (2050s) indicate decreases of 10%. The most affected areas by climate change are located within the Mediterranean areas, the Iberian Peninsula, and Eastern Europe. [ABSTRACT FROM AUTHOR]

The conducted research is of particular importance for the country's food security in the context of climate change in Southeastern Poland. The aim of the research was to determine the influence of climate on the variability of the appearance and the rate of spread of potato blights as the main factor limiting the potato yield in the conditions of Central and Eastern Europe. Combined statistical and simulation modeling methods were used. A mixed effect model was used to detect the effects of temperature, humidity, rainfall and wind speed on potato yield, and partial regression analysis models were used. The natural, agricultural and economic conditions in terms of suitability for potato cultivation were assessed, and factors influencing the fluctuation of the cultivated acreage, yield and harvesting of potatoes were identified. The forecast was based on empirical data from 2000 to 2019. It has been proven that potato cultivation in Southeastern Poland is more vulnerable to climate change than in the rest of the country. The results obtained from analyzing multi-annual results can help policymakers to develop strategies to increase the stability of future potato production and the safety of the crop. This will enable the better use of generated data and methodological approaches to analyze the role of climate, both on a regional and global scale. [ABSTRACT FROM AUTHOR]

Here we provide the first chironomid record and associated summer air-temperature (TVII) reconstruction between ca. 16,800–9100 cal yr BP from Lake Saint Anne (SZA), situated in the Eastern Carpathians. SZA was formed by the youngest volcanic eruption of Ciomadul volcano at ca. 29,600 cal yr BP. Our main goals in this study are to test whether warming after Heinrich event 1 (H1; ca. 16,200 cal yr BP) had similar amplitude to the late glacial warming, while Younger Dryas (YD) summers remained relatively warm in this region of Europe. We found the most remarkable chironomid assemblage change with a TVII increase of ~3.5–3.8°C at ca. 16,350 cal yr BP at SZA, followed by another slight TVII increase of ~0.8–1.0°C at ca. 14,450 cal yr BP. Only very minor temperature variations were recorded between 14,450 cal yr BP and 11,700 cal yr BP, with an unexpected TVII decrease in the Early Holocene. Variations in water depth together with increasing analogue problems and paludification from ca. 14,200 cal yr BP onwards may have influenced the reliability of our paleotemperature record obtained from SZA. In addition, Sphagnum-indicated decreasing pH, and hence decreasing nutrient level, likely overrode the effect of summer air-temperature changes during the Early Holocene, and this may explain the bias in the chironomid-inferred summer air-temperature reconstruction in the Early Holocene section.

The study of the distribution of protected animal species in Europe is especially relevant in a changing climate. Therefore, in this work, we tried to solve the problem of the possibility of habitation of tortoises Testudo graeca Linnaeus, 1758 and Testudo hermanni Gmelin, 1789 in Eastern Europe by using species distribution models (SDMs). We used bioclimatic variables from the CliMond dataset (18 uncorrelated variables of 35) and 19 Paleoclim variables of the "early-Holocene" and "mid-Holocene". Packages Maxent and 'ntbox' were employed. In addition to our data, we used findings listed in the GBIF databases: 1,935 points for T. graeca and 991 points for T. hermanni. It has been shown that subspecies of tortoises differ in the characteristics of the ecological niche. In addition to direct anthropogenic influences, the limiting factor is the "Mean temperature of coldest quarter" (bio11) for both species. Moreover, T. graeca is less demanding and can tolerate both frost and higher temperatures during drier periods than T. hermanni. Modelling found that in the future it is possible for these species will expand in a north-eastern direction, where potentially suitable habitats will appear: by 2090 in the South of Ukraine (Odesa Region, Crimea) and East Ukraine (floodplain of the Siversky Donets River of the Don basin).

This study evaluates the projected changes in the atmospheric water budget and precipitation under the RCP8.5 scenario over two CORDEX-CORE domains: South America (SAM) and Europe (EUR). An ensemble of five twenty-first century projections with the Regional Climate Model version 4 (RegCM4) and their driving Global Climate Models (GCMs) are analyzed in terms of the atmospheric water budget terms (precipitation, P; evapotranspiration, ET; and moisture flux convergence, C). Special focus is on four subregions: Amazon (AMZ), La Plata basin (LPB), Mid-Europe (ME) and Eastern Europe (EA). The precipitation change signal in SAM presents a dipole pattern, i.e. drier conditions in AMZ and wetter conditions in LPB. Over the two European regions a seasonality is evident, with an increase of ~ 25% in precipitation for DJF and a decrease of ~ 35% in JJA. The atmospheric water budget drivers of precipitation change vary by region and season. For example, in DJF the main drivers are related to the large-scale moisture flux convergence, while in JJA over the AMZ atmospheric moisture flux convergence plays only a minor role and local processes dominate. For JJA in the GCMs the high values of the residual term do not allow us to assess which mechanisms drive the precipitation change signal over the AMZ and LPB, respectively. Same conclusions are found for the RegCM4 JJA simulations over the LPB and EA. This points to the importance of the spatial resolution of climate simulations and the role of parameterization schemes in climate models. Our work illustrates the usefulness of analyzing regional water budgets for a better understanding of precipitation change patterns around our globe. [ABSTRACT FROM AUTHOR]

Renewable sources of energy are considered to play a crucial role in the transition towards a decarbonised economy. Central and Eastern European (CEE) countries' positions vis-à-vis the European Union's (EU) renewables goals do not form a homogenous group and have changed over time. After joining the Union, these countries initially supported the EU's renewables targets due to post-accession compliance; however, once this accession legacy faded away, they started to pursue their preferences in a more assertive way, which resulted in different strategies and priorities. The development of CEE countries' positions towards renewables targets is thus connected to the 'emancipation' of these countries and a more assertive way of pursuing their preferences at the EU level, once they were 'freed' from the influence of post-accession conditionality.

• The proposition of transition cycles for a low-carbon economy based on human development and climate action. • A climate justice index in line with the United Nations' concepts of sustainable development. • A climate justice index that benchmarks nations with the same level of economic development. • The proposed index can help policy-makers and national government to identify synergy between climate actions and human development policies. Since the climate change context is increasingly the focus of decision-makers, indices capable of helping them in the transition to a low-carbon economy are considered necessary. Therefore, the objective of this work is to propose an index of climate justice that includes factors of human development and climate action. The index was developed using the Data Envelopment Analysis (DEA) technique and, in this study, assessed the climate justice of 198 nations. After the calculation, statistical analysis was used to compare the climate justice of the aforementioned countries, grouped by level of development and geographical location. The results obtained were: a) there is currently no nation that fully guarantees climate justice to its population; b) there is a difference in the performance of climate justice between the Annex I, Non-Annex I and Least Developed Countries (LDCs) groups; c) nations located in Africa, Latin America and the Caribbean, Asia and Eastern Europe are similar in terms of climate justice index performance. The main contribution of this paper is in the fact that the proposed index can help policy-makers and national governments to define climate and development policies, creating a synergy between such policies.

This article considers why residents of Tajikistan seek out development projects, which are increasingly focused on adaptation to climate change, even as they recognise the limitations of those projects. Experiences of meaningful development during the Soviet era, along with foreign media accounts and migrant experiences abroad, reoriented people's expectations and encouraged them to seek aid. As a result, people sought out personal networks to guide development projects in the hopes of bolstering their ongoing livelihood strategies. Efforts to promote participation in development must account for the desires people hold in order to guide how projects are devised and implemented. [ABSTRACT FROM AUTHOR]

In the context of shifting the boundary of the Quaternary down to the level of 2.6 Ma and including the Gelasian Stage in the Quaternary System, the systematization of the original and published data on the geology and paleogeography of the Late Pliocene and Early Pleistocene of Eastern Europe has been carried out. It was established that, at the boundary of the Gauss and Matuyama paleomagnetic epochs, along with the general trend toward cooling and aridization, profound landscape and climate changes occurred and rhythmic fluctuations of the climate intensified. During the period from 2.6 to 1.8 Ma, corresponding to the Gelasian (pre-Tiglian and Tiglian of Western Europe or Paleopleistocene of Eastern Europe), there appeared subarctic landscapes. In the Eopleistocene (1.8–0.78 Ma) and the Early Neopleistocene (0.78–0.42 Ma), the climate became colder, and climatic zonality repeatedly underwent a complex restructuring, gradually approaching the modern one. Glacial deposits (layers of till) occurring in Eastern Europe date back to the Paleopleistocene. Evidence indicates that there were at least three independent glaciations in the Eopleistocene (1.8–0.78 Ma) and possibly four in the Early Neopleistocene. On the basis of studies of stratotypic sections, paragenetic links were established between sediments of different age within glacial and periglacial areas, and the paleogeographic events of the Early Pleistocene of Eastern Europe were correlated with those within the Western European region.

Various models and datasets related to aflatoxins in the maize and dairy production chain have been developed and used but they have not yet been linked with each other. This study aimed to investigate the impacts of climate change on aflatoxin B1 production in maize and its consequences on aflatoxin M1 contamination in dairy cow’s milk, using a full chain modelling approach. To this end, available models and input data were chained together in a modelling framework. As a case study, we focused on maize grown in Eastern Europe and imported to the Netherlands to be fed–as part of dairy cows’ compound feed–to dairy cows in the Netherlands. Three different climate models, one aflatoxin B1 prediction model and five different carryover models were used. For this particular case study of East European maize, most of the calculations suggest an increase (up to 50%) of maximum mean aflatoxin M1 in milk by 2030, except for one climate (DMI) model suggesting a decrease. Results from all combinations of carryover and climate models suggest a similar or slight increase (up to 0.6%) of the chance of finding aflatoxin M1 in milk above the EC limit of 0.05 μg/kg by 2030. Results varied mainly with the climate model data and carryover model considered. The model framework infrastructure is flexible so that forecasting models for other mycotoxins or other food safety hazards as well as other production chains, together with necessary input databases, can easily be included as well. This modelling framework for the first time links datasets and models related to aflatoxin B1 in maize and related aflatoxin M1 the dairy production chain to obtain a unique predictive methodology based on Monte Carlo simulation. Such an integrated approach with scenario analysis provides possibilities for policy makers and risk managers to study the effects of changes in the beginning of the chain on the end product.

The great web-spinning pine-sawfly Acantholyda posticalis Mats. ( Hymenoptera: Pamphiliidae) is one of the major defoliating insects of pine forests. Mass outbreaks of this species have occurred in Scots pine ( Pinus sylvestris L.) stands in Central Europe and in the southern parts of Eastern Europe and Siberia. Recently, the outbreak range has shifted northward and new outbreaks have been recorded in Estonia and Finland., The dynamics of the supercooling capability of pre-imaginal stages of A. posticalis (eonymphs, pronymphs, pupae) collected from the soil in a pine forest on the Island of Saaremaa, Estonia, were determined., The supercooling points ( SCP) of overwintering eonymphs and pronymphs changed during the winter, although there were no significant differences between the mean SCPs of either larval stage on any measuring date. The mean SCPs decreased from October (−8 to −10 ° C) to January and March (−15 to −17 ° C) and increased once again in May (−9 to −11 ° C). The average SCP of pupae was considerably higher (−5.3 ° C)., Overwintering larvae in the soil are potentially covered by an insulating layer of forest litter, moss and snow, thus avoiding direct exposure to low temperatures. Cold-hardiness in both overwintering larval stages of A. posticalis is sufficient for successful survival during winter in the northern Baltic region., At present, outbreaks of A. posticalis in higher latitudes are concentrated in milder maritime regions near the coast of the Baltic Sea, although these may expand in the future as a result of climate warming, with the sawfly possibly becoming a serious pest of pine forests of northern Europe.

The extreme northeastern Europe constitutes a marginal historical transition zone from the, at least partially, agriculturally based economy of North Russia and the hunting-gathering economy of the indigenous Finnish and Samoyed peoples of the North. Climate and trade are crucial for the economy, and these are assumed to be the two main factors in understanding the regional historical development. I present a multi-archive mean annual temperature reconstruction for northeastern Europe spanning the past two millennia, which is used to develop a comparative chronology of climatic and historical events in the study region. It is argued that climate had a profound impact on the Slavic population’s economy and directions of migration, facilitating penetration into higher latitudes in warmer and abandonment in colder climatic phases. It is virtually certain that the mode and speed of development and northeastward expansion of the Russian State from the Middle Ages to the Modern Time were in many ways dependent on natural and geographical factors.

For the last three decades the entire post-Soviet space saw a cardinal transformation of the land-use structure associated with the transition from a planned to a market economy. These changes influenced the productivity dynamics of agricultural lands. On the other hand, global warming became one further factor influencing crop yield. The primary objective of this study is to assess the possible role of each of these two factors, based on analyzing the trends of biological productivity of agroecosystems for three periods which stand out prominently as regards the priorities of the agricultural policy and characteristics of climatic conditions (the 1980s, 1990s and 2000s). Time series of NDVI GIMMS values, obtained from NOAA AVHRR low-resolution data, were used as the input data in analyzing productivity changes for agrolandscapes in the south of the European part of Russia, Ukraine and Moldova. Analysis of the landscape bioproductivity dynamics for the steppe and forest-steppe zones shows an unambiguous positive trend for the period of the 1980s characterized by stable weather conditions, and by the attraction of large investments in the agrarian sector. An unambiguous negative trend was revealed for the 1990s when all Soviet republics were experiencing a profound economic crisis, combined with extremely unfavorable weather conditions. In the early 21 century, remote sensing data did not show any clear directedness of formlands biological productivity trends. The results obtained are contradictory to the well-established view of a rapid recovery of production potentials in agriculture in countries of Eastern Europe at that period. [ABSTRACT FROM AUTHOR]

Road maintenance in winter using de-icing agents, which is widely used in Eastern Europe, is the cause of water salinization in neighbouring environments, which might lead to biodiversity loss in aquatic ecosystems. In this study, we investigated NaCl toxicity to test young organisms: Daphnia magna and Poecilla reticulata (standard tests organisms). The salinity of NaCl was measured by electrolytic conductivity (EC). It was statistically demonstrated that the test solutions should be prepared using natural water. For D. magna the NOEC was 7.17 mS/cm and the LC50 9.76 mS/cm. Poecilla reticulata showed resistance to salinity up to a conductivity of 25.2 mS/cm, and no lethal effects were recorded for any individual in the test population. The study showed that winter salinities recorded in inland waters (without emergencies such as sudden influx of pollutants due to industrial accidents) are unlikely to affect fish but may be hazardous to small plankton. However, the high dare of D. magna may result in a reduction of planktivorous fish. [ABSTRACT FROM AUTHOR]
