Summary: Based on a social preference survey in Warsaw, this study assesses people's preferences for changes in urban green spaces (UGS) to ensure safe recreation, examining how personal characteristics correlate with preferred changes. The findings suggest that vegetation density and overall share of vegetation are highly important factors in assessing images, while crowding has little effect. Respondents expressed a need for more wild and cultivated vegetation, as well as more places for spending time in UGS. Two major behavioral patterns were identified: those driven by fear of COVID-19 who preferred green spaces closer to their homes and required fewer alterations, and those frequent visitors of UGS who showed no fear of COVID-19 and preferred more wilderness. These findings highlight the importance of increasing UGS diversity.

Summary: Urban green space is a broad concept that includes not only urban parks but also other vegetated areas in cities, known as informal green spaces. These informal green spaces, although not officially recognized, provide similar ecosystem services as parks. Our study examines the different categories of urban green space and highlights the challenges in planning and managing these areas.

Summary: With the rapid development of urbanization, insect pollinators in urban ecosystems are facing challenges such as reduced pollen sources, habitat fragmentation, and damage to nesting environments. Urban green spaces (UGS) play a crucial role in maintaining stable pollinator communities. However, the relationship between the vertical layer heterogeneity and the horizontal layer complexity of vegetation structure in UGS and pollinator communities remains poorly understood. This study aimed to investigate how vegetation structure and environmental characteristics shape the insect pollinator community in UGS. Through a comprehensive survey conducted in Hefei City, China, a total of 11,401 pollinators from 6 orders and 34 families were identified. The results indicated that certain vegetation types, such as successional short-cut shrub and open green spaces, were identified as high-quality insect pollinator habitats. Furthermore, the study revealed that vegetation structure had a greater impact on pollinator communities than environmental characteristics. Factors such as flowering abundance, herb richness, and shrub coverage were identified as the most important factors influencing insect pollinator communities, highlighting the importance of proper plant configuration and management practices in urban green spaces.

Summary: This study analysed the variations of relative humidity in Shenzhen, China over the past 60 years. The results showed three stages of mean annual relative humidity: stable, decreasing, and increasing. The increase in humidity after 2008 was attributed to the city government's policies aimed at improving the ecological environment.

Summary: Rapid urbanization poses a major threat to urban biodiversity and ecosystem services, particularly pollination. This study evaluates the potential of urban green infrastructure for pollinator conservation and identifies an imbalance in the availability of flower resources throughout the year. The study also highlights limitations in the use of Pollination Syndromes as a tool for predicting attracted pollinator groups. Field work is suggested to determine specific plant-pollinator relationships. Further research considering factors such as urban connectivity and fragmentation is needed for comprehensive management of urban pollinators.

Summary: The study found that spontaneous woodlands in Italian cities vary in size and age, predominantly growing on different previous land uses, with residential and industrial areas being the most dominant. Urban planning generally fails to adequately consider spontaneous woodlands, with some exceptions that could serve as models for future planning, while the role of citizens appears to be crucial.

Summary: The process of urbanization has led to the loss of green spaces due to the agglomeration of population in cities and the conversion of rural landscapes. This study examines the effects of monocentric and polycentric urban spatial structures on the size and accessibility of green space in Chinese cities. The findings suggest that compact monocentric structures can improve the size of urban green space, while polycentric structures enhance its accessibility.

Summary: With the advancement of science and computing technologies, fire practitioners are now using operational fire simulation tools to make better decisions during wildfire emergencies. An emerging data-driven approach for wildfire risk estimation has been proposed as a cost-effective alternative to simulations. Applying this approach to use cases in Tasmania, Australia, the results show that the risk metric can accurately estimate imminent risk in operational wildfire management. Furthermore, the knowledge base of this data-driven risk metric can be continuously updated to improve its accuracy.
