Identifying tree species and planting strategies that can achieve these targets is crucial. We applied species-specific tree crown growth models for 20 species commonly planted in Melbourne, Australia to simulate canopy cover increase in newly developed residential suburb over 30 years (2025–2055). Tree species selection and planting strategies were simulated under high and low rainfall. The default strategy represented current tree species selection and planting practices. The two alternative strategies i) occupied all available street planting spaces prioritizing the planting of large crown species at maturity, and ii) occupied all available street planting spaces, maximizing the number of trees planted. Both the default strategy and maximising the number of trees planted achieved 11–15 % canopy cover after 30 years. Prioritising planting trees with large crowns at maturity achieved 16–22 % canopy cover after 30 years. Low rainfall reduced canopy cover in all scenarios by 4–6 %. Increasing the number of species with a large crown at maturity will likely achieve higher canopy cover. However, canopy cover targets will be difficult to achieve unless tree planting on private property increases.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"54 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873900","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}

While definitions of nature-based solutions are commonly referenced in the literature, “nature” itself is rarely defined. This article investigates the ideas of nature in nature-based solutions discourses in urban planning and argues that unpacking their connotations is crucial for a more precise and locally sensitive development of planning for humans and more-than-humans. The findings reveal that “nature” is often used abstractly or through proxies such as ecosystem services or biodiversity. Although the place-specificity of NBS is recognized in the literature, local definitions and values of nature are not sufficiently included, which can compromise the long-term uptake of NBS. The study further highlights the growing recognition of the plural values of nature and the potential for ecocentric approaches to challenge the anthropocentric underpinnings of NBS. The article concludes that unpacking the often-diverging meanings of nature is paramount for a more conscious development of NBS research in planning theory and practice, enhancing the effectiveness, inclusivity, and environmental justice of NBS initiatives and their effective mainstreaming. By embracing plural definitions of nature and fostering a deeper understanding of human-nature relationships, NBS research can support more sustainable, resilient, and equitable urban futures.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"32 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873956","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, there is a lack of field survey-based research on large-scale thermal comfort assessment across continuous urban spaces. To address this gap, this study developed a framework for assessing outdoor thermal comfort. A total number of 668 onsite observations from field studies during the daytime on typical summer days were collected and used for model development. The sites were distributed in diverse local climate zones (LCZs) of Hong Kong, enabling the prediction of outdoor thermal comfort across the city under different urban settings. A neural network model was trained for predicting daytime outdoor thermal comfort based on both meteorological and morphological variables. Universal Thermal Climate Index (UTCI) was used to indicate objective measures of human thermal comfort. The model was then applied to wider urban layouts and dynamic climatic conditions. The results revealed that during extreme hot conditions, approximately 74.8% of areas experienced strong to extreme heat stress, with thermal sensations classified as hot or very hot, while the remaining 25.3% fell under moderate heat stress. High levels of thermal stress were observed in urban layouts of low-rise buildings, with LCZ 3 showing the highest extreme heat stress percentage at 61.3%, followed closely by LCZ 6 at 57.6%. In both LCZs, over 90% of areas faced strong to extreme thermal stress. These findings are crucial for identifying urban regions with high thermal stress. The framework could be valuable for cities with similar climate and geographical contexts.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"86 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816555","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 vulnerability of <ce:italic>peri</ce:italic>-urban communities, especially during the COVID-19 pandemic concerning park utilization, goes beyond what objective assessments of access and quality can capture. Based on a multidimensional and comparative framework and combining objective evaluation and subjective perceptions and demands, this study explores park equity within Salt Lake City during COVID-19, spotlighting variations between urban and <ce:italic>peri</ce:italic>-urban areas. The analysis identifies pronounced regional disparities in park equity measures. The southern <ce:italic>peri</ce:italic>-urban community is identified as a disadvantaged group regarding accessibility by traditional spatial measures, yet their own perception of accessibility remains optimistic. While the urban center and west <ce:italic>peri</ce:italic>-urban groups generally share similar objective accessibility indices, their perceptions vary, and a discernible west-east disparity in park quality emerges, especially in terms of amenities. The analysis of demands and preferences also shows that western residents have a higher need for essential infrastructure enhancements to offset their current underdeveloped parks. The COVID-19 pandemic further magnified these disparities, emphasizing western communities’ vulnerabilities as they are more likely to be affected by quality perception issues than the other two groups. Additionally, the intricate and non-linear dynamics of park visitation choices during the pandemic highlight the necessity for a cross-disciplinary synthesis in urban planning paradigms.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"7 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789999","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}

With a United States representative survey (<ce:italic>n</ce:italic> = 1,200), we measured beliefs and intentions to engage in personal-sphere (i.e., individual), social diffusion (i.e., encouraging others to act), and civic action behavior (e.g., voting). A latent class analysis (LCA) revealed four distinct groups within the population: Disengaged, Potential Adopters, Potential Amplifiers, and Potential Advocates. Each class comprised approximately one-quarter of the United States population. We found that certain groups are more receptive to personal-sphere behavior, while others may be more receptive to social diffusion behavior or civic action behavior. The groups varied by key distinguishing characteristics: perceptions around civic action, previous personal-sphere and social diffusion behavior, and intentions to engage in personal-sphere action. Findings revealed opportunities to create tailored public engagement strategies to engage different groups in urban biodiversity conservation behavior.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"4 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790001","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}

We mapped the distribution of front yard flower gardens compared to four other front yard landscaping types (lawn, shrubs, non-vegetated, and weeds) across 86,429 addresses in Greater Boston, MA, USA using Google Street View. We complemented these data with on-the-ground surveys at a stratified random subset of 519 yards. We hypothesized that census tracts with higher incomes would have higher flower garden frequencies and that these gardens would have higher species richness, and that census tracts with larger lots would also have higher flower garden frequencies and species richness. Yards identified as flower gardens using Google Street View contained around double the cultivated floral species richness of lawns and more than any other yard type. However, flower gardens were infrequent in front yards, and were a substantial front yard cover type in only 2.3 % of yards. Flower garden frequency and cultivated species richness were greater with higher census tract income, both consistent with the luxury effect hypothesis. However, higher-income lots also had more lawns and fewer spontaneous (weedy) species. Surprisingly, flower gardens had higher frequencies in census tracts with smaller lots. In our region, flower gardening appears to be constrained by income or education but not lot size, pointing to the potential role of small urban lots as a target for pollinator habitat.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"66 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142782357","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}

To effectively gauge the impact of PAs for biodiversity conservation, it’s imperative to delve into not only the pattern but the process of biodiversity. Adopting a dynamic view for biodiversity assessment, our study established a synergistic approach within a systematic conservation planning framework, focusing on comprehensively assessing the future conservation effectiveness of PAs. Four modeling techniques were integrated in the process to estimate conservation priorities under various future scenarios: SLAMM and Dyna-CLUE projected future land-use changes, MaxEnt predicted shifts in habitat suitability for key species, and Zonation identified conservation priorities thereby. The results indicated a potential shift in conservation priorities over time from inland to coastal areas across different cities in the GBA, highlighting the substantial mismatches between current PAs and high-priority areas in Guangdong and the urgency for prompt conservation actions. Moreover, our findings revealed that proposed PA system has not sufficiently prioritized wetland conservation, nor has it effectively conserved amphibian, plant and bird species.

Whilst research has shown heterogeneous supplies of ecosystem services existing in Green Belts, it is unclear how and whether Green Belts as landscapes may change in the future beyond their urban containment bounds. Though participatory scenarios have been extensively applied to landscape planning, they have not to English Green Belts. Addressing these gaps, a cross-sector stakeholder workshop was held to co-develop exploratory Green Belt landscape scenarios nationally in 20 years’ time. Three scenarios: “Intensify & Diversify”, “Build-Build-Build” and “Multifunctional” were framed on a governance-functionality axis, identifying future drivers, impacts and assumptions. The scenarios reveal Green Belts are under increased pressure from multiple land-uses, societal demands, and policies, many of which are in conflict, stemming from either a prioritisation or balancing of these demands through varying governance mechanisms. Stakeholder critiques and visions reveal a substantial cross-sector consensus for more (multi)functional Green Belts in England, including as “strategic urban support landscapes” to adapt and mitigate threats associated with climate change. Finally, complementary landscape photo-visualisations of “fictitious” landscapes were produced, aided by artificial intelligence, highlighting the growing potential of these tools to support landscape research.
