This study focuses on the chances of major cities (over 100,000 inhabitants) in the Pannonian Basin to win the European Green Capital Award. The 28 cities covered by the analysis can be divided into two groups: eleven cities that have already applied (one of them, Ljubljana was a previous winner) and seventeen cities that have not yet applied for the award. During the research, we divided the cities according to these two groups. In the study we applied various statistical and spatial analysis methods to capture similarities and differences in their environmental indicators. The results show that there are no significant differences in environmental indices between these two groups, and the values of the 2016 winner city (Ljubljana) are most similar to Austrian, Slovenian, and Croatian cities. Furthermore, based on the results of the similarity search, it can be stated that the further east we go, the less similar the examined cities are to Ljubljana. We also examined the probability of reaching the finals, indicating that cities that have not yet applied have a low likelihood of winning the award.

The lack of precipitation may cause severe damage in different sectors, especially in agriculture and forestry, therefore, its analysis is a key element of adaptation strategies in the changing climate. In the present study, we selected different climate indices as important indicators for forests to investigate the current and future wet and dry conditions in summer in Hungary. For the historical period (from 1971), the observation-based HuClim dataset is used, which already shows a slight drying trend in the past 50 years, especially in June. For the future, regional climate model simulations from the EURO-CORDEX program are used, taking into account two different RCP scenarios (a business-as-usual scenario and an intermediate mitigation scenario, i.e., RCP8.5 and RCP4.5, respectively). Since mitigation starts to affect the climate system after about 20 years, results do not differ substantially for the two scenarios until 2060, however, the simulated changes highly depend on the applied RCP scenario in the late 21st century. Based on the De Martonne Index, a large expansion of semi-arid conditions is projected for the future in July and even more in August. The analysis of the Forestry Aridity Index shows that the steppe category will become dominant in 2081–2100, while the category optimal for beech may disappear entirely from Hungary according to the RCP8.5 scenario.

The results of studies of mountain-meadow soils of the Crimean Mountain plateaus (yailas) within the range of heights from 580 to 1,493 m a.s.l. are presented. The aim of the research is a comparative analysis of the full-profile soils of the mountain meadows distributed on the western and eastern parts of the Main Ridge of the Crimean Mountains and their correspondence to similar soils of nearby mountain ranges. According to the results obtained, the soils of the western yailas are classified as Phaeozems and Umbrisols, while the eastern ones are mostly classified as Chernic Phaeozems. Chernic Phaeozems differ from Phaeozems and Umbrisols by higher values of the humification rate and the optical density of humic acids. In the humus horizons of Phaeozems and Umbrisols, the average values of the of humification rate varied from 21 to 31 percent, and Chernic Phaeozems from 27 to 34 percent. The optical density varied from 12.7 to 18.7 in Phaeozems and Umbrisols, and from 22.2 to 24.2 in Chernic Phaeozems. The climatic feature of the western yailas is the predominance of winter precipitation, or their relatively uniform distribution between warm and cold seasons, while at the eastern yailas the precipitation of the warm season prevails which may be responsible for the revealed differences in soil properties.

The article investigates changing attitudes to memory politics in Ukrainian city of Kharkiv. In February 2022, with the outbreak of the full-scale Russo-Ukrainian war, this geopolitical fault-line city became a frontline city with significant potential outcomes for urban identity and local geopolitical preferences, including attitudes to the national memory politics. The research is based on the comparative analysis of the two surveys among residents of Kharkiv, conducted in spring-summer 2018 and in autumn 2022 – before and after the full-scale war. The results of the surveys are analysed by means of descriptive statistics and binary logistic regression. Additionally, two focus groups were held in order to receive additional justification when interpreting the results of the survey. The research shows that the attitudes to Ukrainian nation-centric memory narrative, including both decommunisation and decolonisation, have significantly improved. Nevertheless, public attitudes to the memory politics in the frontline city are highly reflexive in nature and deeply embedded in the context of the ongoing war. The geopolitical divide, which existed before the war, has largely transformed into a cultural one, namely heterogeneity of attitudes to the Russian cultural heritage in the city. This softened albeit still existing divide has, to some extent, materialised in physical space and runs between the ardent supporters of decommunisation and decolonisation that massively fled from the atrocities of the war and their opponents who at most choose (or were obliged) to stay in the front-line city. The study reveals that military conflicts may either activate hidden geopolitical divides in geopolitical fault-line cities or contribute to their transformation or even disappearance.

Economic development in post-transition countries is dominated by the performance of capital cities, although second-tier cities are also important drivers of development. However, peripheral regions struggle with problems of adaptation and response, often leading to brain drain and economic decline. Industrial strategies highlight those tradable sectors of the economy that favour leading edge KIBS firms and advanced manufacturing, while neglecting the residentiary economy that is more sheltered from competition and provides jobs in local production and services sectors. Our research is inspired by the burgeoning literature of the ‘foundational economy’ approach to economic development, focusing on mundane economic activities providing essential goods and services, and we investigate the differences of economic performance across the NUTS3 regions in selected CEE countries. We study regionally aggregated, firm-level financial and employment data including sectoral classification of the companies with 10+ employees. Our position is that a well-functioning foundational economy is necessary for the whole local economy to work efficiently in the long run. Moreover, increasing productivity in the foundational economy should lead to more regionally balanced growth than an exclusive focus on the ‘frontier firms’ that are highly concentrated spatially as the regional productivity gap in the case of certain foundational activities is not necessarily large.

The study aims to verify the relationship between the unemployment rate and economic growth in European Union (EU) regions. As the most important macroeconomic relationship, the significance of the dependence between the labour market situation and the output growth is widely known and considered. Analysis in this research was conducted using data for 229 EU regions on the NUTS-2 level in the years 2013–2019. In order to verify the relationship between the unemployment rate and the output growth, the spatio-temporal models for pooled time series and cross-sectional data (TSCS) were estimated. The Fitted Trend and Elasticity Method of verifying Okun’s law was used in the analysis, wherein the deterministic trend factor was enriched with the spatial element. Educational attainment as the additional explanatory variable was included in the models. The neighbourhood between regions was quantified based on two criteria: (1) common border criterion – related to the possibility of population migrations, and (2) similarity of the unemployment rate criterion – related to the imitation effect in the issue of introduced rules and regulations on the labour market by regional governments. One of the hypotheses verified in the investigation is the superiority of the economic neighbourhood over the geographical neighbourhood.

Since the early 1990s, Latvia has experienced high levels of emigration. Still, current dynamics show that net migration has nearly ceased and that a growing share of new immigrant populations are from non-European countries. One of the leading causes of a sizable share of recent immigration is the globalisation of higher education and the mobility of international students. However, in recent decades, international student mobility (ISM) has brought attention to various aspects of higher education, educational export, and migration trends. This has captured the interest of academics and practitioners worldwide. Receiving countries recognise the importance of attracting international students as potential residents, especially as they undergo unfavourable demographic changes. The paper aims to present empirical evidence on ISM in Latvia by assessing international student daily life and study experiences. The focus is on examining the perspective of a host country. The study utilises statistical data, survey data and a case study of the University of Latvia to analyse the link between the origin of the student and their choosing Latvia as a non-traditional destination for quality higher education. The findings indicate that Latvia is an attractive destination for young migrants from diverse geographies, including Europe and Southeast Asia and consistent flows of students from former Soviet countries. One of the main factors that draw international students to Latvia is the affordability of education offered in English, providing a “second chance” for achieving success and specific clusters of degree students from European countries studying medicine.
