Understanding how social networks facilitate the adoption of marginal urban greening actions can provide valuable impetus to guide transformative change in urban landscapes, which are under multiple social and environmental stressors globally. Social network mapping of resource flows, particularly information sharing, is one tool for understanding the emergent and transformative urban greening practice of landscaping roadside verges with native and/or waterwise plants. Urban roadside greening in Perth, Western Australia, while formerly prohibited, is now increasingly accepted and advocated for by multiple sectors, as a nature-based solution that provides multiple ecosystem services and social-ecological benefits. This study drew on participatory stakeholder mapping to examine the stakeholder network of non-residential actors connected with verge greening. Using social network analysis, we found almost 80% of resource flows across a large network of diverse stakeholders were information related. We identified top providers, recipients, brokers, as local and state governments and peak bodies, and, to a lesser extent, key individuals, community groups, nurseries, residents and environmental consultants and developers. The network was characterized by four dominant and five smaller communities, which we classified into a typology based on composition, structure (quantitative material), and contextual knowledge, including function, dominant roles and responsibilities (qualitative material). These were the ‘planning and development hub’, ‘governance enablers’, ‘water efficient hub’, ‘greenspace hub’. The five smaller communities were ‘advocates’, ‘transformers’, ‘new vision’, ‘local networks’ and ‘early adopters’. The network analysis provides evidence of communities that transcend traditional sector or actor silos, commonly converging around local governments as key knowledge brokers.

Urban green spaces are becoming increasingly important due to their multitude of ecosystem services. Until now, the focus of environmental impact assessment has been mainly on greenhouse gas emissions. Hence, this study aims to assess common green spaces in Vienna with the method of life cycle assessment for the impact categories climate change, fine particulate matter formation, marine eutrophication and terrestrial acidification over the whole life cycle. A utility lawn (UL), a meadow lawn (ML) and a perennial bed are compared with each other based on the functional unit (FU) of 1 m² covered area over 30 years. Further, combinations of UL and ML with each other and with two different pathway options are assessed in hypothetical park compositions. Results show that the UL as intensively maintained green space has higher environmental impacts compared to extensively maintained ones (ML, perennial bed); e.g., in the impact category climate change ML and perennial bed have an impact of 2.90 and 10.68 kg CO₂ eq./FU, respectively compared to UL with 54.59 kg CO₂ eq./FU. Overall, the maintenance phase is a hotspot in every assessed impact category. When increasing the size of UL this leads to a reduction of environmental impacts; e.g., a 2.5 times bigger area reduces the GWP by over 50 %. When combining UL and ML, the marine eutrophication potential can be reduced significantly due to less fertilizing and mowing. A combination of green space and pathways does not result in a large increase or a significant reduction in environmental impacts.

城市绿地因其多种生态系统服务而变得越来越重要。到目前为止，环境影响评估的重点主要集中在温室气体排放上。因此，本研究旨在采用生命周期评估方法，评估维也纳常见绿地在整个生命周期中对气候变化、细颗粒物形成、海洋富营养化和陆地酸化等类别的影响。以 30 年内 1 平方米覆盖面积的功能单位（FU）为基础，对公用草坪（UL）、草甸草坪（ML）和多年生花坛进行了比较。此外，还在假定的公园组合中评估了 UL 和 ML 的相互组合以及与两种不同路径方案的组合。结果表明，与广泛维护的绿地（ML、多年生花坛）相比，密集维护的 UL 绿地对环境的影响更大；例如，在气候变化影响类别中，ML 和多年生花坛对环境的影响分别为 2.90 和 10.68 千克二氧化碳当量/单位，而 UL 绿地对环境的影响为 54.59 千克二氧化碳当量/单位。总体而言，在每个评估影响类别中，维护阶段都是一个热点。增加 UL 的面积可减少对环境的影响；例如，面积增加 2.5 倍，全球升温潜能值就会降低 50%以上。将 UL 和 ML 结合在一起时，由于减少了施肥和除草，海洋富营养化的可能性会大大降低。绿地和路径的结合不会导致环境影响的大幅增加或显著减少。

Land value is a crucial indicator of economic dynamics and regional development, providing essential information for urban planning and policy development. However, most existing studies estimate a singular land value over large areas, lacking the fine-grained details for urban management. This study therefore develops a RAHGV (relative-to-absolute hybrid generative valuation) framework for regional land valuation, which combines a hybrid learning strategy with deep generative modeling to produce high-resolution, spatially continuous land value distribution across extensive urban areas. In a case study of New York City (NYC), the RAHGV model outperforms typical one-step models by differentiating between local land variations and broader regional tendencies. Its bi-attention bottleneck significantly improves model performance, reducing MAE (Mean Absolute Error) by 45.75% and MSE (Mean Squared Error) by 69.86% compared to conventional deep generative methods. Local physical infrastructure and mixed land-use patterns primarily influence micro-scale land values, while community amenities and economic vibrancy drive macro-scale values. The findings highlight the potential of the RAHGV framework as a powerful tool for promoting sustainable urban development by delivering high-resolution, data-driven insights that support informed decision-making in rapidly evolving urban environments.

Urbanization poses significant threats to pollinators, but they may respond differently to habitat modification according to their nesting and foraging requirements. Despite the diversity of pollinator groups and species found in urban areas, research often focus on bees, neglecting other groups. Whether bee response to urbanization suffice in representing the wider pollinator spectrum, however, is poorly understood. Here, we examined how urbanization impacts the interaction networks between plants and different pollinator groups and evaluated the dissimilarities of urban green spaces at both local and regional scales within a Neotropical metropolis. Recording 1,404 interactions between 262 plant and 220 pollinator species, we found that network specialization varied among pollinator groups but was not affected by urban impervious surface cover. Such lack of difference may happen owing to the prevalence of generalist species across urban environments. Importantly, urban green spaces showed high dissimilarities in species and interactions, emphasizing the heterogeneity found across the urban landscape. Plant composition also varied between urban green spaces and was strongly correlated with interaction dissimilarities, indicating that floral resources contribute to unique interactions found in different areas. Our results suggest that although important, bees alone do not represent the wider response of pollinators to urbanization. Furthermore, the high dissimilarities influenced by site specific plant-pollinator co-occurrence underscore that multiple and connected green spaces are required to safeguard plant-pollinator interaction diversity and its vital ecosystem function in cities.

Urban sustainability relies on maintaining a delicate balance between humans and nature. Urban rooftop farming (URF) has emerged as a potentially transformative practice in this regard. However, ensuring effective implementation of URF requires appropriate parameters that align with citizens’ ambitions. This study delves into residents’ experiences practicing URF in Dhaka city, advocating for a separate policy to sustain this sector and enhance the megacity’s overall environmental health. The research explores URF implementation in Dhaka and scrutinizes urban residents’ engagement with this practice through YouTube video analysis. The study uses binary logistic regression to examine the associations between residents’ socio-demographic characteristics and their motivations for URF participation. Additionally, K-means clustering techniques identify distinct groups of urban gardeners based on their recommendations for government organizations. The findings reveal that a predominantly male cohort with minimal URF training engages in the practice across diverse social strata, resulting in varied motivations. Gardeners in mixed land-use neighborhoods exhibit robust motivation, notably seeking URF policy guidelines and information hubs from government institutions. The study underscores the importance of inclusive stakeholder perspectives in effective policy formulation. It calls for integrating insights from government bodies, developers, and specialists to address URF within Dhaka city’s intricate urban fabric.

This article presents a spatially integrated method for forest management planning and outdoor recreation in forest areas. A survey of 1402 respondents with varied socio-demographic profiles assessed the recreational attractiveness of forest areas. We classified silvicultural regimes into four categories (no management, low, medium, and high-intensity management) and mapped the potential attractiveness of forest areas by means of exploratory spatial data analysis using the Corine Land Cover and Geoportal database. The analysis involved three levels: local (1×1 km grid), district, and regional. By applying local Moran’s I, an indicator of spatial association, the study identified “hotspots and outliers” of recreational attractiveness at a landscape level. The identification of spatial association types served as the foundation for making recommendations for forest planning. The findings indicate that a specific combination of site and terrain characteristics influences perceived attractiveness as respondents showed the highest recreational preferences for old multispecies stands located on terrain with pronounced relief. Nature conservation, surface water, and cultural heritage sites substantially enhanced the recreational attractiveness of forest areas. Our model may be a valuable tool for identifying the recreational attractiveness of forest areas and guiding specific regional forest management strategies. It provides useful information for aligning silvicultural planning with the preferred recreational variant, enabling the identification of forest areas with a given type of recreational attractiveness and implementing forestry practices conducive to enhancing ecosystem services.

Neighborhood greenspaces are widely known to benefit bird diversity and human mental health. However, whether bird richness mediates the relationship between greenspace and mental health is unknown. We ascertain such mediation effects in 294 census tracts in Los Angeles City. We obtained greenspace data from one-meter resolution satellite imagery, bird species data from eBird citizen science datasets, and prevalence of poor mental health from the US Centers for Disease Control and Prevention. Mediation analysis combined with spatial error models was used to assess the mediating effects while controlling for geographic, demographic, and socio-economic factors. We found that the higher greenspace percentage was associated with increased bird richness (β = 0.188, p < 0.001), and such bird richness was associated with reduced prevalence of poor mental health (β = − 0.020, p = 0.010). The bird richness partially mediated the relationship between the greenspace percentage and the prevalence of poor mental health, as evidenced by a decrease in coefficient efficiency from − 0.020 to − 0.017. Our findings underscore the need for public health policymakers, landscape architects, and greenspace managers to consider biodiversity-friendly strategies in the design of urban greenspaces to enhance both wildlife habitats and human mental health.

Urban greenspaces significantly influence the ecological environment, resident health, and sustainable development of cities. Fractional vegetation cover (FVC) is a common measure of urban greenspace, and a long-term FVC dataset is required to characterize the dynamics of vegetation in a complex urban environment along with socioeconomic development. This study proposed a data fusion method to integrate multiple existing satellite-based FVC datasets to create a spatially and temporally seamless FVC dataset at a 30-m resolution, which was applied to urban greenspace mapping for 12 representative cities in China for the 2000–2020 period. In addition, the distribution and changes in the equality of urban greenspaces exposure during the study period were examined by integrating the 30-m FVC datasets with a population-weighted exposure framework. Greendays are defined as the annual duration for which urban residents enjoy greenery throughout the year. The results suggest that greenspace in the 12 cities showed an upward trend, with greendays displaying a slight overall extension. The magnitude of the increase in greenspace and greendays was generally greater in peri-urban areas than in core urban areas. Equality in urban greenspace exposure remained high and improved over time. This research offers essential data support for urban planners and policymakers, contributing to more informed management of urban greenspaces.

Fractional vegetation cover (FVC) is a common measure of urban greenspace, and a long-term FVC dataset is required to characterize the dynamics of vegetation in a complex urban environment along with socioeconomic development. This study proposed a data fusion method to integrate multiple existing satellite-based FVC datasets to create a spatially and temporally seamless FVC dataset at a 30-m resolution, which was applied to urban greenspace mapping for 12 representative cities in China for the 2000–2020 period. In addition, the distribution and changes in the equality of urban greenspaces exposure during the study period were examined by integrating the 30-m FVC datasets with a population-weighted exposure framework. Greendays are defined as the annual duration for which urban residents enjoy greenery throughout the year. The results suggest that greenspace in the 12 cities showed an upward trend, with greendays displaying a slight overall extension. The magnitude of the increase in greenspace and greendays was generally greater in <em>peri</em>-urban areas than in core urban areas. Equality in urban greenspace exposure remained high and improved over time. This research offers essential data support for urban planners and policymakers, contributing to more informed management of urban greenspaces.

Landscape planning and design holds the potential to contribute to efforts toward repairing our growing psychological disconnection with nature. To do so, however, it is important to know what types of environmental features impact how connected to nature certain environments make us feel. The present study used a novel application of network analysis to identify which environmental features are most important for nature connection experiences. In this research, 205 participants completed online surveys in which they reported the presence or absence of a variety of environmental features during four previous nature connection experiences. They also indicated their level of recalled nature connectedness for each experience. The network analysis revealed that the most positively important features were those commonly found in rural nature (e.g., wild nature, animals, and mountains or hills). Features reflecting human presence (e.g., buildings, paved roads, vehicles) were most negatively important. Features commonly found in semi-rural nature (e.g., trees and meadows) were seemingly only important insofar as they were associated with the wilder features. Additionally, trails, wild nature, and mountains or hills were three of the features most central to nature connection experiences, suggesting that they are particularly important for how they support other parts of the network. Overall, from a purely nature-connection perspective, these findings support the need for increased rewilding efforts—more than simply increasing basic access to urban nature—and also limiting the overt presence of human development. Other more nuanced findings are also discussed.

Rural exodus from European mountain regions to lowlands has triggered natural reforestation of abandoned lands in the 19^th and 20^th centuries, altering the provision of ecosystem services and creating management challenges. Post-abandonment forests are complex ecosystems that respond over time and space to several drivers. Their management requires integrated approaches that involve insights from historical ecology. Our study aimed to assess the influences of the land-use legacies on post-abandonment forest overstory and understory and provide insights on suitable management strategies. We assessed these influences using multiple scales (from landscape to field scale) and ecological approaches (vegetation, forest, and landscape ecology).

We identified post-abandonment forests within a western Alps watershed through a land-use/land-cover change detection from 1954 to 2017. Field surveys were conducted in three different land-use legacy types (i.e., transitions from former grasslands, wood-pastures, and sparse forests to dense forests) to analyse forest overstory and understory. We explored the influences of land-use legacy on post-abandonment forests through redundancy analysis, using forest overstory and understory variables as response variables and environmental factors as predictors. Our study revealed successional and environmental differences among post-abandonment forests, notably depending on the historical presence of biological legacies: forests originating from former wooded areas exhibited ecological conditions closer to natural trajectories, while those resulting from abandoned grasslands still express conditions similar to the pre-abandonment ones. Based on our findings, we discuss how the direct implications of land-use legacies on post-abandonment forests can provide insights into their management.
