Multiple factors shape the interaction of people with urban greenspace: Sweden as a case study

This study identifies and analyses multiple factors that impact people's interactions with urban greenspace in Sweden. An unrestricted, self-selected online survey was used to collect the data. The survey questions were related to individual characteristics of respondents, including socio-demographic characteristics, self-reported nature connectedness, and self-reported constraints to greenspace usage; perceived characteristics of urban greenspace, including its availability, quality, and accessibility, and benefits and problems; and preferences of respondents regarding types of urban greenspace and activities. Additionally, several spatially explicit variables were included in the analysis. A total of 2806 respondents from 208 (of 290) municipalities completed the survey. Our findings indicate that greenspace users are highly heterogeneous and utilise diverse green spaces along the urban-peri-urban gradient for various benefits. The statistical analyses identified 61 explanatory variables that affect the frequency of interactions with urban greenspace. In addition, we identify key factors that shape critical differences between frequent and infrequent urban users, such as nature connectedness, perceptions of urban greenspace functions, and their perceived accessibility. Our results highlight the complex challenge facing urban planners and managers of green spaces, who have to consider and integrate a vast array of factors influencing the willingness of increasingly diverse urban populations to interact with greenspace

Understanding people’s interactions with urban greenspace: Case studies in Eastern Europe

This study explored and compared people’s interactions with urban greenspace (UGS) using case studies in three Eastern European countries – Armenia, Georgia and Ukraine. These countries have experienced radical changes in governance systems and socio-economic structures, characteristic of a transition from planned to market economies. Recently, Armenia, Georgia and Ukraine have been arenas for armed conflicts, which have dramatically heightened instability throughout the region. Urban planners in Eastern Europe therefore urgently need context-relevant knowledge to facilitate the critical work of (re-)building more inclusive, safe, resilient and sustainable cities. An unrestricted, self-selected online survey was used to collect data in 2021–2022. A total of 3573 respondents completed the survey (N = 1142 in Armenia, N = 1069 in Georgia and N = 1362 in Ukraine). We identified 12 key explanatory factors linked to the frequency of people’s interactions with UGS using multiple ordinal logistic regressions. The core findings are: (i) most factors are country-specific; (ii) age of respondents had a large effect on the frequency of UGS use in Armenia and Georgia, where older people were mostly infrequent users of UGS; (iii) those who lived further from UGS or could not access it on foot were less likely to use it often; and (iv) the only common key factor across three countries was that people who ‘do not want’ to use UGS are infrequent users. The study shows that only 10–18% of respondents were satisfied with the UGS availability and quality. Among many constraints related to UGS use, litter in UGS and lack of time were the most mentioned. Large parks were the most preferred types of UGS. Our findings confirm the need for urban planners in Eastern Europe to consider and integrate diverse factors influencing people’s willingness to interact with urban nature. A priority is to understand how to bring infrequent users to UGS, particularly older people in various cultural settings in Eastern European countries

Challenges for transboundary river management in Eastern Europe – three case studies

The transboundary river basins shared between Russia, Ukraine and the European Union pose unique challenges for management because of differences regarding not only the legal framework but also related to monitoring practices and water utilization. Using the example of three river basins – the Desna (shared by Russia and Ukraine), the Western Dvina (shared by Russia, Belarus, Lithuania, Estonia and Latvia) and the Western Bug (shared by Ukraine, Belarus and Poland) – this paper provides an analysis of current challenges with respect to transboundary water resources management in Eastern Europe. This assessment is based on a comparison of similarities and disparities concerning the physical and human geography of the basins (and their national sub-basins) as well as specific problems related to water pollution caused by urban, agricultural and industrial water usage both in the recent past and today. All three catchments have a similar size, climate and hydrological characteristics. However, there are different challenges regarding up- and downstream sections of the respective basins: pollution input in the Western Bug originates primarily from upstream sources in Ukraine and Belarus, whereas ecological problems in the Desna and Western Dvina persist principally downstream, i.e. in Ukraine respectively Belarus and Latvia. Despite some differences between the basins, it is concluded that interstate cooperation is an important prerequisite for integrated water resources management (IWRM) in all of the studied basins. This analysis identified several key challenges related to start or continue with IWRM, including pollution mitigation, improved monitoring, appropriate governance, climate change and its effect on water balances in the catchments, capacity development and thorough system understanding

Structural phase transformations in annealed Pt/Mn/Fe trilayers

Thermally-activated phase transitions in Pt/Mn/Fe thin films were investigated by a combination of x-ray diffraction, transmission electron microscopy, secondary neutral mass spectrometry depth profiling, atomic force microscopy, and magnetic properties measurements. Post-annealing was carried out in vacuum to different temperatures up to 620 °C. Initially, at temperatures between 280 °C – 450 °C first L10-MnPt is formed at the Mn/Pt interface followed by the most likely formation of metastable bcc Fe3Pt, which gets transformed by further annealing to fcc Fe3Pt and eventually to chemically ordered L12-Fe3Pt. The final product after annealing at 620 °C consists of two interesting phases, which are relevant for spintronic applications, antiferromagnetic L10-MnPt with addition of Fe and ferromagnetic L12-Fe3Pt, consistent with the initial element composition
