While this approach is garnering increased research attention, practitioners rarely integrate sound into their practice beyond noise mitigation. Yet, sound design of public spaces has long been a major focus of sound installation artists, who offer creative site-specific interventions to (re)design public spaces. In this study, we present the systematic evaluation and comparison of four temporary sound installations deployed over two consecutive summers in the same urban public space. The sound installations featured compositions by the artist collective Audiotopie using different combinations of ambient music, nature, and vocal sounds. To measure the effects of the sound installations on users’ experience, we deployed 825 questionnaires including soundscape ratings and sound source listings. The results show that all four sound installations improved the public space’s soundscape, with commonalities (increased <em>calmness</em> and <em>pleasantness</em>, decreased perceived loudness) and specificities (increased sense of <em>being-away</em> for one installation, increased <em>extent-coherence</em> and reduced ratings for <em>chaotic</em> for another) related to compositional and contextual factors, such as the intended design goals, users’ location, or the presence of construction noise. As well, three of the four installations distracted participants from other non-dominant sound sources such as construction works, air conditioners, but also birds and human voices. Overall, the results confirm that sound installations can have a common enhancing effect on the experience of public space users, in addition to specific, tailored effects to reinforce the intended design goals in public spaces.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105173"},"PeriodicalIF":7.9,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0169204624001725/pdfft?md5=9ffd2ec57502d7fe80b38b8e1874603a&pid=1-s2.0-S0169204624001725-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141862143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides producing quality food for urban residents, urban agriculture could provide diverse and non-tangible ecosystem services that still need to be explored. While prior research has investigated direct stakeholders’ (e.g., urban farmers and growers) perspectives on ecosystem services from urban agriculture, the general public’s perception and underlying factors remain less understood. Such understanding is crucial as the broader community, beyond direct stakeholders, will benefit from urban agriculture and influence the policy and planning that determines its development trajectory. This study investigated the general public’s perception of ecosystem services associated with urban agriculture in the Miami Metropolitan Area, a region experiencing rapid urbanization and emerging urban agriculture development. Among 23 services surveyed, community-level cultural and regulating/supporting services were the most recognized. Conversely, individual-level cultural and provisioning services were the least recognized, underscoring the recognized contribution of urban agriculture to a much larger community and society. Respondents’ demographics, personal experience with farming/gardening, and awareness of urban agriculture in their surroundings were the significant factors, whereas geographic factors (e.g., land-use cluster) exerted less impact. Our findings highlight the perceived multifunctionality of urban agriculture from a public perspective and suggest a nuanced understanding of how urban agriculture contributes to social well-being. Our research provides empirical evidence of public support for urban agriculture development and has critical implications for urban regions interested in integrating urban agriculture to achieve urban sustainability.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105170"},"PeriodicalIF":7.9,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141862189","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 aimed to address this significant knowledge gap by using real-world driving experiments. Each of thirty-four residents performed seven driving tasks so 238 driving tasks were completed in total. Each task lasted one hour and followed a randomly assigned sequence. Road greenness and other environmental characteristics were analyzed using deep transfer learning semantic segmentation based on live videos (30 frames per second), recorded by a camera positioned to capture the driver’s eye view. A serial communication technology, known as Controller Area Network bus (CANbus), was employed to continuously measure driving performance using four parameters. A series of hierarchical regression analyses yielded three major findings: First, an increased mean of greenness was associated with improved driving performance, as demonstrated by all four parameters. Second, an increased variation of greenness was also associated with better driving performance in three parameters. Finally, the mean of greenness displayed a stronger positive relationship with driving performance than the variation of greenness in three parameters. The findings imply that both the quantity and quality of green landscapes are critical for promoting driving performance in urban areas.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105156"},"PeriodicalIF":7.9,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768888","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}

Much research has focused on the demands for more urban greenspace; far less has examined issues concerning supply. Better understanding of the dilemmas faced by those charged with the task of providing urban greenspace at the city scale can help policymakers, planners, and aligned professions ensure that municipal resources are appropriately and justly allocated. We aim to address this gap, answering two research questions: 1) what factors shape urban greenspace provision, and 2) how do these factors manifest differently for municipalities of Australia and New Zealand? We surveyed 82 local government officers/officials from mid-size municipalities of nine Anglophone countries about their experience providing municipal greenspace. We expose some of the experiences, challenges, and emerging issues facing contemporary municipal greenspace providers globally, including the drivers and barriers to urban greenspace provision. Findings reveal the complexities of supplying urban greenspace, shaped by multiple factors. While funding, community expectations, and governance tools, are the main factors, funding is the main barrier to providing urban greenspace globally. Moreover, almost all other factors affect availability of sufficient funding. Key differences for Australia and New Zealand reveal a broadening conceptualisation of the purpose of parks: more so multi-purpose than primarily sport and recreation. Revealing challenges greenspace managers face in delivering adequate urban greenspace and facilities, these findings question the efficacy of the current planning approaches embedded in planning legislation, municipal greenspace plans and strategies.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105172"},"PeriodicalIF":7.9,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0169204624001713/pdfft?md5=ea5c768fccad1c7a934c2b81822ed969&pid=1-s2.0-S0169204624001713-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this we asked municipal urban forest professionals working in Canadian municipalities with a UFMP to answer an online survey. The survey: 1) characterized UFMP development; 2) assessed the level of achievement of UFMP objectives; 3) assessed which municipal characteristics led to UFMP objective achievement; and 4) assessed professional views on the outcomes of having a UFMP. Based on n = 118 responses across Canada, we found that UFMPs have been published frequently in the last 20 years, with a peak during the period 2010–2014. On average, and as shared by the respondents, the level of achievement of UFMP objectives was over 50 %, indicating good progress in UFMP implementation. We found no statistically significant differences in the level of UFMP objective achievement by type of city or language of community (English/French), among other factors. There was a consensus among professionals that increasing financial resources for urban forests was an expected outcome of having an UFMP, although there were also diverse and complementary views about the outcome of a UFMPs. A key finding was that climate change objectives are not being implemented or included in UFMPs at high levels. While focused on Canadian cities, this study also provides guidelines on how to assess UFMP implementation across case studies, as well as insights regarding the management objectives that are being overlooked in plan implementation. This may enable future work by researchers and practitioners working in fields related to nature-based solutions, green infrastructure, urban climate adaptation, and sustainable cities worldwide.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105168"},"PeriodicalIF":7.9,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0169204624001671/pdfft?md5=47d30c92d864a2f08f55d3e455cf8699&pid=1-s2.0-S0169204624001671-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As cities begin to plan for urban biodiversity alongside other land use considerations, planners can leverage ecological knowledge and conservation planning concepts to aid decision making to deliver benefits for nature and people. Here we demonstrate how targeted green infrastructure placement can potentially increase the delivery of landscape level benefits for biodiversity by improving connectivity for native species. We measure the change in ecological connectivity when parking spaces are converted to small green spaces across the City of Melbourne, Australia. We test three reallocation scenarios with varying levels of parking space conversion to green infrastructure and varying levels of spatial prioritisation to ecological connectivity. While the scenario that maximised the number of parking spaces converted performed best, we show that <em>targeted</em> greening delivered the strongest connectivity outcomes per unit of area converted. Improvements in connectivity were two times higher per unit effort when conversion was targeted towards locations identified as potentially important barriers to landscape-level movement.

Greater awareness of the ecosystem services provided by urban forests over the last two decades has led to an increased interest in improving urban forest management. In Canada, the conditions of management are usually articulated by a municipal government in an urban forest management plan (UFMP). This study responds to previous studies on the content of Canadian UFMPs to provide a more comprehensive and updated comparison of UFMPs across Canada. While previous research has examined the content of UFMPs at a moment in time, and often when far fewer plans existed, in this study we consider changes in content over time and the influence of the social-ecological characteristics of municipalities on this content. We combined quantitative and qualitative content analyses, including topic modelling text analysis algorithms and interpretative thematic coding, to extract content, in the form of topics or themes, from 74 UFMPs. We assessed the distribution of these topics and themes by year of publication, and the influence of social-ecological characteristics upon this distribution using standard correlation and means differences analysis procedures. We found that Canadian UFMPs contain a broad number of themes and topics but are dominated by ideas referring to increasing tree abundance. Comparatively less attention is being paid to climate change and community stewardship. Mentions of increasing tree abundance and climate change rose over time. There was also a greater mention of administration, community education, and increasing tree abundance in smaller municipalities. Canadian municipalities may be well positioned to increase the abundance of urban forests given current management conditions. While abundance itself is beneficial, increasing abundance without addressing issues related to biodiversity, vulnerability of urban forests to climate change, and community stewardship, is a management trade-off that could, for example, increase abundance in the short term, but increase vulnerability in the long term. While focused on Canadian cities, this study also provides guidelines for possible cross-country comparisons and reflections on how UFMPs can be powerful management and planning tools for a climate-resilient and sustainable future.</p></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"251 ","pages":"Article 105154"},"PeriodicalIF":7.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0169204624001531/pdfft?md5=b3664523196966bd24239da9390e82dc&pid=1-s2.0-S0169204624001531-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Residential open space (ROS) plays a significant role in shaping the older adults’ health and well-being. However, there is a lack of evidence for the association between various types of ROSs and the older adults’ emotions. The purpose of this study is to examine and compare the effects of ROSs of different qualities on the older adults’ physiological and psychological responses relevant to emotions. Three types of ROS (poor, medium, and high quality) were selected, and data from 69 older adults were collected through a real-world field experiment using multiple wearable sensors. Residential outdoor characteristics were quantified objectively through visual-perception indices and perceived restorativeness subjectively. The emotions were analyzed based on skin conductance level, heart-rate variability, electroencephalogram, and a psychological questionnaire. The results show that compared to exposure to the poor-quality ROS, exposure to the high-quality ROS led to a significantly lower increase in SCL and a higher improvement in vigor. Significant differences in β/α indices were found across the three types of ROS. In addition, the emotional effects of the visual-perception characteristics differed according to ROS type. Blue space and safety were negatively associated with the older adults’ emotional arousal in the high-quality ROS, while safety and walkability were negatively related to the older adults’ emotional arousal in the poor-quality ROS. The effects of greenery, visual crowdedness, and enclosure on the older adults’ emotions produced mixed findings among the different types of ROS. The findings of the research can offer guidance for urban planners to improve the design of ROS to provide more emotionally pleasing and age-friendly experiences.","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"9 1","pages":""},"PeriodicalIF":9.1,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141631648","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}
