How this expansion occurs should consider what people expect from trees based on how they experience and perceive these trees. Therefore, we need a better understanding of how people perceptually respond to urban tree abundance. This research examined whether people’s satisfaction with urban trees and satisfaction with the management of those trees were related to objective measures of greenery such as the Normalized Difference Vegetation Index (NDVI), percent tree canopy cover, and the Viewshed Greenness Visibility Index (VGVI) for trees. We used a demographically and geographically representative survey of 223 residents in Toronto, Canada, and calculated NDVI, canopy cover, and VGVI at three neighbourhood sizes. We analysed the data using generalized linear regression. We found that canopy cover and VGVI had a positive association with satisfaction with urban trees. The associations were comparatively stronger at larger neighbourhood scales than at smaller scales. There were no statistically significant associations with NDVI or satisfaction with the management of urban trees.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-023-00119-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48401763","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}

Knowledge complexity is considered essential for economic development and innovation, and recent studies find complex economic activities of many fields concentrate more in large cities. However, it remains unclear whether the urban concentration tendency would differ by explicit and tacit knowledge, given the latter is often argued as the hard core knowledge more difficult to transfer. We measure explicit/tacit knowledge in job descriptions regarding education/experience requirements. Our analysis reveals that knowledge of different natures differs to a great extent in their property of urban concentration. Specifically, jobs requiring greater explicit knowledge show higher urban scaling rates. This, however, is not true for tacit knowledge, as it demonstrates the exact opposite pattern. Our findings suggest that while cities are centers of knowledge and innovation, the engines of continued growth tend to become more biased towards explicit rather than know-how knowledge.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-023-00116-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47264080","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}

However, the specific contribution of tree versus nontree vegetation has not been adequately studied in the context of urban greening and rapid urbanization. In this study, we investigated the spatiotemporal variations of urban tree and nontree coverage in China during 2000–2020 by using satellite observations. Results show the nationwide mean urban tree coverage increased by 0.073 ± 0.511% per year (mean ± 1 standard deviation), while nontree vegetation coverage decreased by 0.584 ± 1.022% per year. We found that the majority of mega- and large cities had a contrasting vegetation pattern, with significantly ascending trends in both tree and nontree coverages in urban core areas but descending trends in peri-urban areas. These trends were positively associated with multiple greenness indices, suggesting the importance of the vegetation structure for growth and productivity in urban areas. This study highlights the predominance of enhancing vegetation growth in urban areas primarily driven by significantly increasing tree cover in China, and can further serve as a reference for global vegetation study.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-023-00111-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45485471","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}

It has affected how and where people live, work, shop, and play, and exposed our cities’ vulnerabilities, leading to calls for a health lens to be applied in designing, approving, and evaluating city plans. Socioeconomic, spatial and health inequities have been amplified, particularly for those living in inadequate or poorly designed housing, neighbourhoods, and cities. Hence, city mayors have committed to ‘build back better’ with all daily living amenities within a 15-min walking or cycling trip. Designed well, these cities have the potential to be healthier, more sustainable, equitable, and resilient. Yet their delivery requires a rethink of city planning. Drawing on lessons from the COVID-19 pandemic, we argue that to reduce the risk of future pandemics, we must mitigate climate change, limit urban expansion, and use nature-based solutions to protect natural habitats and biodiversity. We then explore how healthy, sustainable, and resilient 15-minute cities could be planned to reduce emissions and ensure our cities are more resilient in the event of future crises. Given that higher density housing underpins the success of 15-minute cities, we also examine how to create more resilient housing stock, through well-implemented health-supportive apartment design standards. Finally, we argue that to achieve all this, cross-sector leadership and investment will be vital.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10236403/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9624213","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}

Circular building practices emphasize restorative design principles, which can significantly reduce the amount of virgin material used and the environmental footprint of buildings. When combined with digital technologies, circular practices can achieve even higher environmental benefits. Such technologies enable visualization of the environmental impact along the entire value chain, facilitating smart design, production, and use to increase material- and eco-efficiency. However, realizing the full potential of these trends requires more than just technological advancements. Institutional, behavioral, and socio-economic system changes are essential to effect a transition towards a circular and digital economy. To facilitate such a transition, a new form of governance is needed, in which network governance complements conventional public governance. Network governance fosters the formation of coalitions of willing partners that jointly strive towards the goal of system change, creating a fertile ground for a new economic paradigm, behavioral change, government regulation and innovation. The effectiveness of network governance in supporting public governance depends on the specific socio-cultural and political context of a country. However, a thoughtful application of this governance model can facilitate the building sector’s journey towards greater material- and environmental efficiency.","PeriodicalId":74322,"journal":{"name":"npj urban sustainability","volume":" ","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42949-023-00109-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47171844","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}
