Purpose: This paper explores the enduring repercussions of the COVID-19 pandemic on global supply chains by investigating the experiences and adaptations of organizations in Poland, Georgia, and Turkey. It seeks to provide valuable insights into the long-term implications of the pandemic on supply chain management, with a focus on strategies and challenges faced by businesses in different regions. Design/Methodology/Approach: We conducted an extensive study utilizing an online questionnaire to gather primary data from a diverse sample of organizations in Poland, Georgia, and Turkey. This research approach is quantitative and comprehensively assess the pandemic's impact on supply chains. We analysed responses from a range of industries, enabling a holistic understanding of the topic. In addition to descriptive analysis, we conducted a comparative examination of the three countries using ANOVA (Analysis of Variance) to assess any significant differences among them. Furthermore, we employed Cramér's V, a robust statistical measure, to investigate associations between categorical variables within the dataset Findings: The research reveals that the outcomes in three distinct countries are surprisingly similar, contrary to initial expectations. The majority of the proposed COVID-19 factors exhibit no statistically significant distinctions among Poland, Georgia, and Turkey. Consequently, we can infer that the COVID-19 pandemic exerted a considerable and widespread impact on the entities under consideration. Research Limitations: Despite our efforts to gather a representative sample, the study may not encompass all industries and organizations equally. Additionally, the research is subject to the limitations of self-reported data and potential bias in responses. The focus on specific regions may not capture the entirety of global supply chain dynamics. Practical Implications: This research provides practical insights for organizations navigating supply chain challenges in a post-pandemic world. It offers guidance on building resilient and adaptable supply chains and managing risks effectively. Businesses can use these insights to make informed decisions and enhance their supply chain strategies. Originality/Value: Drawing from our own research conducted in three countries after the official conclusion of the pandemic, this study adds a distinctive contribution to the current body of literature. It takes a long-term perspective on the repercussions of the COVID-19 pandemic on supply chains, specifically emphasizing diverse regions. The employed methodology and regional comparisons offer a nuanced insight into the dynamic evolution of the supply chain landscape, underscoring the importance of adaptability and resilience. In contrast to various studies conducted at the onset and during the pandemic, this paper uniquely seeks to discern the enduring effects.

Semi-natural, extensively managed grassland communities are among the most species-rich plant communities. The species number and floristic composition depend on numerous factors, both natural and associated with human activity, both present and past. In European countries, a system of subsidies for farmers is used to preserve extensive, usually unprofitable management of multi-species grassland communities. The development of specific recommendations requires knowledge of the main factors shaping grassland plant communities. A study was carried out in seven regions of the Polish Western Carpathians, in areas with traditional sheep grazing. Plant species composition (phytosociological relevés) of 517 plots were surveyed in different grassland types. For each plot, topographic parameters, i.e. slope, aspect and altitude, were recorded and land use in the past was read from historical maps. The aim of the study was to a) assess differences in the species composition of grassland vegetation between topographically and historically different regions of the Polish Carpathians, and b) to identify the main factors influencing species composition in each of these regions. Depending on the region, different factors contributed most to explaining the variation in the species composition and species numbers. Topographic factors played a decisive role. The type of past use (arable land or grassland) had little influence on current biodiversity. The results of the study indicate the need for a localised approach to developing principles for protection of grassland biodiversity.

There are ca 1,492 thousand tractors currently used in Poland, with the average power of 45.3 kW. There are 9.8 ha of agricultural land per one tractor, their average age is ca 25 years and the degree of wear 77%. There are between 20 to 30 thousand tractors newly registered per year, however, these are both new and used tractors imported from abroad. These new registrations, which also reflect new purchases, are diverse depending on the region. Based on the 2018 records of the Central Register of Vehicles and Drivers (CEPiK), the paper establishes essential parameters of the registered tractors, such as price, power, age, depending on the region. There were 25,422 records under analysis, as some of the original records were dismissed as errors after verification. It was established that in the western part of Poland, with farms twice or three times bigger than in the rest of the country, the purchased tractors were characterized by higher power and lower age and, consequently, higher prices (81-95 kW, 14-18 years, PLN168-186 thousands). In contrast, the tractors in south-east Poland, where the dominant farms are of agricultural land below 10 ha, had worse parameters (76-86 kW, 14-18 years, PLN76-86 thousands).

Obecnie w Polsce używanych jest około 1 492 000 ciągników ze średnią mocą 45,3 kW. Na jeden ciągnik przypada 9,8 ha użytków rolnych, ich średni wiek wynosi 25 lat a stopień zużycia 77%. W ciągu roku rejestrowanych jest pomiędzy 20 a 30 tysięcy traktorów, jednakże są to zarówno nowe i używane traktory przywiezione z zagranicy. Te nowe rejestracje, które odzwierciedlają także nowo zakupione ciągniki są zróżnicowane w zależności od regionu. Na podstawie rejestrów wpisanych do Centralnej Ewidencji Pojazdów i Kierowców (CEPiK), niniejszy artykuł określa istotne parametry zarejestrowanych ciągników, takich jak cena, moc, wiek w zależności od regionu. Analizie poddano 25 422 rejestry, ponieważ po weryfikacji część z oryginalnych wpisów zostało odrzuconych jako błędne. Ustalono, że w zachodniej części Polski, gdzie gospodarstwa są dwa lub trzy razy większe niż w pozostałej części kraju, zakupione traktory charakteryzowały się dużą mocą i młodszym wiekiem a w konsekwencji wyższymi cenami (81-95 kW, 14-18 lat, 168-186 tysięcy zł). Przeciwnie, ciągniki w południowo-wschodniej Polsce, gdzie przodujące gospodarstwa posiadały użytki rolne poniżej 10 ha, miały gorsze parametry (76-86 kW, 14-18 lat, 76-86 tysięcy).

The aim of the paper is to measure and forecast concentration of regional development potential on a regional basis. The study covered 14 GUS features, which measure the development potential. The forecast, nominal values and processes’ dynamics were calculated for data from 2010 to 2020, using author made method. The study reveals that key factors determining the diversification of the distribution of the potential include the relation of large agglomerations to their regional surroundings. Therefore, we are dealing with growth poles with different impact levels. Since 2010, the process of concentrating potential in Poland has taken different directions. In poorly developed regions, we observe constant distribution values. Most regions, especially those with medium and high levels of economic development, are characterized by a dynamic increase in the level of concentration 5% to 6% annually. This means that the growth poles «move away» from their surroundings and strengthen their position. Simultaneously, they slightly reduce the distance to the strongest developed region in Poland (Mazowsze). By 2020, these trends will remain unchanged, however regions with a moderately low level of development will observe the fastest growth.
