Decades of research on multifunctional Green Infrastructure (GI) has yet to translate into holistic implementation in the built environment. This oversight stems from assumptions that many ecosystem services occur passively and thus potential synergies are overlooked during planning and design. This study offers specific guidance for coordinating GI planning, design, and construction by examining the current state of academic literature on these aspects. It identifies 15 GI elements (e.g., green roofs) and 15 objectives (e.g., biodiversity) to collectively consider before implementation. The literature tends to isolate discussions of “engineered” GI elements with water-related objectives, while more “natural” GI are linked to biodiversity and human well-being. Coordinating across GI objectives and elements remains imperative, but evaluating too many options risks a paradox of choice. This study recommends short-term adherence to principles of adaptive design and, in the long-term, reemphasizes multifunctionality assessments, inter and transdisciplinary collaboration, and political will.
数十年来对多功能绿色基础设施 (GI) 的研究尚未转化为建筑环境中的整体实施。这种疏忽源于人们认为许多生态系统服务是被动提供的，因此在规划和设计过程中忽略了潜在的协同作用。本研究通过考察有关这些方面的学术文献现状，为协调 GI 规划、设计和施工提供了具体指导。它确定了 15 个 GI 要素（如绿色屋顶）和 15 个目标（如生物多样性），以便在实施前共同考虑。这些文献倾向于孤立地讨论与水相关目标的 "工程 "地理信息系统要素，而更 "自然 "的地理信息系统则与生物多样性和人类福祉相关。协调不同的地理信息系统目标和要素仍是当务之急，但评估过多的选项可能会造成选择悖论。本研究建议在短期内坚持适应性设计原则，在长期内再次强调多功能性评估、跨学科合作和政治意愿。

Amidst the COVID-19 pandemic, speculations on the decline of major cities have surged, with studies noting temporary population decreases across various cities worldwide. However, research scarcely addresses the pandemic’s enduring influence on perceptions of city living. Rather than exploring mid- to long-term impacts, current literature focuses mainly on comparing changes in residential preferences during and before the pandemic. To fill this gap, we conducted a randomized conjoint experiment to scrutinize altered residential preferences and attitudes toward residing in the Tokyo Metropolis due to the pandemic. Scenarios encompassed reminders of potential pandemic re-occurrence and teleworking options. Despite variations depending on the scenarios and socio-demographic characteristics of the survey participants, overall, results show that the COVID-19 pandemic and the surge in remote working did not diminish the allure of Tokyo, implying a low probability of an urban decline. These outcomes advocate for compact urban development to bolster resilience against forthcoming stressors like climate change.

In this paper we illustrate how normalised practices and strategies of waste management pay insufficient attention to social life and distributional impacts by excluding apartments and placing them at the margins of domestic waste management. In considering shifts towards more circular post-consumption systems, this paper describes the problematic policy and regulatory imaginary of apartment waste management within the Circular Economy narratives of sustainable domestic waste management. We present an argument for a relational approach to domestic waste as a counterpoint to technocentric and market-based approaches, with implications for governance and infrastructures of apartment waste management. We illustrate how spatio-temporal and socio-material bundles of practices could chart new directions for reduction and collection. We seek to demonstrate how relational place-based measures and shifts in practices in Victoria and elsewhere could counter exclusionary infrastructure by more purposefully including the marginal spaces that apartments inhabit.

With the recent expansion of urban greening interventions, the definition of spatial indicators to measure the provision of urban greenery has become pivotal in informing the policy-design process. By analyzing the stability of the population and area rankings induced by several indicators of green accessibility for over 1000 cities worldwide, we investigate the extent to which using a single metric provides a reliable assessment of green accessibility in a city. The results suggest that, due to the complex interaction between the spatial distribution of greenspaces in an urban center and its population distribution, a single indicator may inadequately differentiate across areas or subgroups of the population, even when focusing on one form of green accessibility. From a policy standpoint, this indicates the need to switch toward a multi-dimensional framework capable of organically evaluating a range of indicators at once.

Global climate change has been shown to cause longer, more intense, and frequent heatwaves, of which anthropogenic stressors concentrated in urban areas are a critical contributor. In this study, we investigate the causal interactions during heatwaves across 520 urban sites in the U.S. combining complex network and causal analysis. The presence of regional mediators is manifest in the constructed causal networks, together with long-range teleconnections. More importantly, megacities, such as New York City and Chicago, are causally connected with most of other cities and mediate the structure of urban networks during heatwaves. We also identified a significantly positive correlation between the causality strength and the total populations in megacities. These findings corroborate the contribution of human activities e.g., anthropogenic emissions of greenhouse gases or waste heat, to urban heatwaves. The emergence of teleconnections and supernodes are informative for the prediction and adaptation to heatwaves under global climate change.

Urban livability has become a major policy and practice priority in many parts of the world. However, its attainment remains challenging in many cities of developing and emerging economies. The lack of data with appropriate quality, coverage, and spatial and temporal resolution often complicates both the assessment of livability in such cities and the identification of priority areas for improvement. Here we develop a framework to mobilize and synthesize open-source data to analyze spatially urban livability patterns in Shanghai. The framework brings together diverse types of open-source data including housing characteristics, population distribution, transportation networks, and points of interest to identify city areas with low livability, and thus priority areas for improvement. Such findings can provide a comprehensive overview of the residential living conditions in Shanghai, as well as useful information to urban planners and decision-makers. Furthermore, subject to data availability, the proposed method has the potential for application in other cities.

Understanding the relationship between spatial structures of cities and environmental hazard exposures is essential for urban health and sustainability planning. However, a critical knowledge gap exists in terms of the extent to which socio-spatial networks shaped by human mobility exacerbate or alleviate urban heat exposures of populations in cities. In this study, we utilize location-based data to construct human mobility networks in twenty metropolitan areas in the U.S. The human mobility networks are analyzed in conjunction with the urban heat characteristics of spatial areas. We identify areas with high and low urban heat exposure and evaluate visitation patterns of populations residing in high and low urban heat areas to other spatial areas with similar and dissimilar urban heat exposure. The results reveal the presence of urban heat traps in the majority of the studied metropolitan areas, wherein populations residing in high-heat exposure areas primarily visited other high-heat exposure zones. Specifically, cities such as Los Angeles, Boston, and Chicago were particularly pronounced as urban heat traps. The results also show a small percentage of human mobility to produce urban heat escalation and heat escapes. The findings from this study provide a better understanding of urban heat exposure in cities based on patterns of human mobility. These findings contribute to a broader understanding of the intersection of human network dynamics and environmental hazard exposures in cities to inform more integrated urban design and planning to promote health and sustainability.

Growing urban population and contemporary urban systems lock-in unsustainable urban development pathways, deteriorating the living quality of urban dwellers. The systemic complexity of these challenges renders it difficult to find solutions using existing planning processes. Alternatively, transformative planning processes are radical, take place on multiple scales, and are often irreversible; therefore, require the integration of local stakeholders’ perspectives, which are often contradictory. We identify perceived levers of urban transformative change using a serious game to facilitate the integration of these perspectives through simulating neighbourhood transformation processes in two European case studies. Building on existing transformation frameworks, we organize, conceptualize, and compare the effectiveness of these levers through demonstrating their interactions with different scales of transformation. Specifically, drawing from close commonalities between large-scale (Three Spheres of Transformation) and place-based (Place-making) transformation frameworks, we show how these interactions can help to develop recommendations to unlock urban transformative change. Results show that access to participation is a key lever enabling urban transformative change. It appears to be mid-level effective to unlock urban transformative change through interactions with the political sphere of transformation and procedural element of Place-making. Ultimately, however, most effective are those levers that interact with all scales of transformation. For example, by engaging a combination of levers including access to participation, public spaces, parking, place-characteristics and place-identity. These findings could be operationalized by self-organized transformation processes focused on repurposing hard infrastructure into public spaces, whilst ensuring continuity of place-based social- and physical features. Local stakeholders could further use such processes to better understand and engage with their individual roles in the transformative process, because interactions with the personal scale, i.e., personal sphere of transformation appear paramount to unlock urban transformative change.

Increasing frequency of climate-related disruptions requires transformational responses over the lifecycles of interconnected urban systems with short- and long-term change dynamics. However, the aftermath of disruptions is often characterised by short-sighted decision-making, neglecting long-term urban shifts. In this study, we present a first attempt to develop the theoretical foundation for temporal dynamics for increasingly disrupted yet ”connecting and moving” cities that can be used in planning for urban resilience. Using the lens of climate urbanism, we conceptualise the interplay of temporal dynamics to empirically examine how planning practice perceives and addresses temporality in two regions - Amsterdam, the Netherlands, and Mumbai, India. Our findings reinforce that disruptions do not inform long-term planning. Endogenous and exogenous dynamics of change are not viewed together nor used to embed short-term planning goals within long-term resilience visions. To address the lack of systematic planning approaches that can leverage temporal dynamics, we propose two options for temporally flexible urban planning processes.

While heat mitigation is crucial to achieving sustainable urban development, an inadequate understanding of the evolution of the urban thermal environment (UTE) and its relationship with socio-ecological systems (SESs) constrains the development of effective mitigation strategies. In this study, we use satellite observations from 2000–2021 to explore the evolving impact of SES interactions on the UTE of 136 Chinese urban areas. The results reveal a nonlinear intensification of the UTE over the period and an indication that an increasing number of urban areas have successfully applied UTE mitigation measures. Spatio-temporal patterns in UTE are shown to be strongly influenced by social and ecological factors and their interactions, whereby the higher the SES status, the stronger the decreasing UTE trend. These findings highlight the need for, and advantages of, developing win-win solutions for urban society and ecology and have important implications in creating integrated strategies for heat mitigation in promoting urban sustainability.

Spatio-temporal patterns in UTE are shown to be strongly influenced by social and ecological factors and their interactions, whereby the higher the SES status, the stronger the decreasing UTE trend. These findings highlight the need for, and advantages of, developing win-win solutions for urban society and ecology and have important implications in creating integrated strategies for heat mitigation in promoting urban sustainability.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-024-00141-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139523324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
