Among these conflicts, interactions with snakes are particularly common and among the deadliest forms of human–wildlife conflicts in the tropics. However, they remain poorly understood in many rapidly developing cities in this region. In this study we used participatory science data on human–snake encounters in the Bangkok region—a rapidly urbanising tropical mega-city in Thailand—to explore how human–snake conflicts vary with urbanisation and to assess the linkage between healthcare systems and snake encounter hotspots. The Bangkok region accounted for one-third of the country’s total snake encounters species during our February 2021–January 2022 study period. Our analysis revealed complex dynamics in human–snake conflicts, identifying urbanisation intensity and grassland cover as major drivers of snake encounter rates and species richness. Recent urban expansion and subsequent grassland conversion tend to escalate human–snake conflicts, suggesting that a compact city approach could serve as a mitigation solution whilst promoting sustainable urban development. Notably, urban tree-cover had no significant impact on snake encounters, suggesting that policies aimed at increasing tree-cover may not affect human–snake conflicts in tropical cities. Areas with high snake encounter risks were not positively associated with availability, accessibility, and capacity of hospitals, highlighting critical gaps in healthcare systems concerning human–snake interfaces. Our study provides a valuable insight to inform integrated urban planning and public health management that emphasise the need to balance development with habitat preservation, prioritises healthcare accessibility in high-risk areas, and promote public education through online participatory science platforms to mitigate human–snake conflicts and enhance ecosystem resilience in rapidly urbanising tropical cities.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"269 ","pages":"Article 105582"},"PeriodicalIF":9.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145962146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the Industrial Revolution caused water pollution and conflicting river usage, ultimately leading to the prohibition of urban river bathing in major European cities during the 20th century, a ban that remains in effect in many places today. In recent years, a grassroots movement has been emerging in across Europe, advocating for the revival of river bathing, fuelled by the growing demand for natural interactions during hot summers and a renewed connection between cities and rivers. This article presents a pioneering synthesis of urban river bathing in the European context, developed under the auspices of the interdisciplinary Consortium on Urban Bathing. It draws on multidisciplinary literature review, policy analysis, fieldwork conducted in 11 European cities, and interviews with 26 stakeholders. The study identifies two types of urban river bathing designs: designated river pools and free river bathing zones, each with distinct regulations and management approaches. The analysis critically examines current management practices, addressing water microbial quality and health risks under EU Directive guidance, alongside river drowning prevention and safety protocols in case study cities. Finally, it discusses the sustainability potential of developing urban river bathing by proposing strategies for collaborative river governance and responding to the growing impacts of climate change, emphasizing the ignored ecological consideration. These findings serve as the foundation for an interdisciplinary framework to understand the evolution, management, and sustainability of this globally emerging subject.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"269 ","pages":"Article 105596"},"PeriodicalIF":9.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146072087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using spatial regressions within a Piecewise Structural Equation Modeling (PSEM) framework, this study investigates both direct associations between two UGS types (e.g., trees and grass) and FMD, as well as indirect pathways through land surface temperature (LST), air pollution (PM<sub>2.5</sub>), and anthropogenic noise. Findings reveal that UGS types have distinct, and often opposing, non-linear associations with FMD and its environmental mediators. Tree canopy exhibits a direct negative association with FMD, with diminishing marginal effects as canopy cover increases, and a U-shaped association with PM<sub>2.5</sub>, while grass shows positive associations with FMD and PM<sub>2.5</sub> concentrations. Although both UGS types are negatively associated with LST and noise levels, trees show a significantly stronger association with temperatures. We also identify significant racial and ethnic heterogeneity in these associations. The overall negative marginal effect of tree canopy on FMD is significant in communities of color but statistically insignificant in predominantly White tracts. This disparity is driven by both direct association with FMD and indirect pathways through LST mitigation, which are significant only in communities of color. These findings challenge one-size-fits-all greening narratives and provide evidence for context-specific, equity-oriented UGS planning aiming at mitigating urban mental distress and advancing restorative environmental justice.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"269 ","pages":"Article 105598"},"PeriodicalIF":9.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beside attempts to halt urbanization, urban planners can control urban forms, i.e., the spatial configuration of artificial areas within and around cities.

It is commonly predicted that compact cities should exhibit low biodiversity levels at their center while preserving the biodiversity of peri-urban areas, whereas the opposite pattern should be observed in sprawled cities. To test whether these trade-offs can actually emerge from existing urban forms, we simulated the genetic diversity of urban and peri-urban animal populations in 325 European cities. We delineated them by standardizing the proportion of artificial areas to 20 %, and distinguishing urban green spaces from forest habitats. We then modeled the indirect interplay of urban forms (irrespective of the degree of urbanization), the connectivity of these two habitats, and their respective genetic diversity. Our statistical path modeling results revealed an overall negative effect of urban sprawl on habitat connectivity, and consequently on genetic diversity in both habitat types. Interestingly, forest habitat connectivity was a better predictor of genetic diversity in the urban populations of the simulated species than was urban green space connectivity. This reflected the importance of preserving peri-urban habitats from urban sprawl, as they may act as biodiversity sources for city centers. Accordingly, efforts to foster biodiversity within cities should not overshadow the large-scale impacts of urban sprawl on peri-urban biodiversity.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"269 ","pages":"Article 105586"},"PeriodicalIF":9.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145981802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study comprehensively analyzed the variations in vegetation phenology responses to UI gradients across 233 cities in China. The results showed that the response of vegetation phenology to UI was different between urban cores and suburban areas, owing to the distinct urban environmental characteristics of the two types of regions. A nonlinear association of vegetation phenology to ISA (impervious surface area, as an indicator for UI) was observed over both urban cores and suburban areas. The differences in both SOS (start of the growing season) and EOS (end of the growing season) between urban cores and suburban areas noticeably increased with increasing ISA, indicating that the SOS and EOS delayed more with intensive urbanization in urban cores than in suburban areas. When the ISA ranged from 90 to100%, the average SOS in the urban cores of all 233 cities in China was 2.31 days later than that in the suburban areas. Among the 172 cities studied, 105 experienced a delayed SOS in urban cores with respect to that in suburban areas, with delays ranging from 0.17 to 43.92 days. Moreover, the data showed a significant spatial heterogeneity in the differential response of vegetation phenology to varying UI gradients when comparing urban cores with suburban areas. Phenological differences were observed between cities in different geographic zones and ecoregions across China. For Northwest China, greater urbanization leads to larger SOS delay and more notable GSL (growing season length) reduction in urban cores relative to suburbs, reflecting a spatial pattern of vegetation phenology along the urbanization gradient in the region. These quantitative findings suggest that it is important to take account of the effects of urban environments in studying the phenological responses to future climate change.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"269 ","pages":"Article 105578"},"PeriodicalIF":9.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145981718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brownfield sites—abandoned, contaminated, or underused parcels within urban areas—present challenges and opportunities for sustainable urban development. Redeveloping these lands can improve environmental and social indicators and enhance the overall quality of life. This study proposes a spatial agent-based model to support the allocation of appropriate future land use subclasses to previously identified brownfield parcels, using Geographic Information Systems (GIS) and a rule-based, parcel-level ABM implemented in Python (Mesa-Geo). The model employs a fully vector-based structure with cadastral parcels as computational decision units (agents). The research was conducted in Region 7 of Tehran, encompassing 39,551 parcels, of which 110 were identified as brownfields. Land use subclasses were allocated based on planning indicators such as dependency, consistency, entropy, physical suitability, and per-capita service indicators, while zoning codes and parcel-size thresholds act as exogenous spatial constraints. The findings demonstrate the model’s effectiveness in supporting planning-oriented sustainable redevelopment through spatially informed, indicator-driven land use decisions.
