Yet, access to sustainable dining options remains highly uneven due to complex interactions between socioeconomic systems and individual behaviors. Here we introduce an integrated framework for evaluating sustainable dining accessibility, leveraging data from 3,649 menu items and 112,892 restaurants in Tokyo, Japan. Our findings highlight a pronounced clustering of restaurants around railway stations, underscoring the pivotal role of transit-oriented development in shaping urban dining patterns. Then, a sustainable dining choice was assessed through a multidimensional approach that incorporates economic preferences, environmental impacts along the supply chain and the nutritional quality of menu offerings. Further analysis uncovers severe inequalities in sustainable dining accessibility across station vicinities, railway lines and administrative wards, with up to 9 million daily passengers exposed to unsustainable dining environments. To address these disparities, we propose targeted interventions, including optimized restaurant spatial distribution, to enhance accessibility in underserved areas. By integrating these solutions, this study offers actionable insights for urban planners, policymakers and citizens, contributing to planetary health and advancing sustainability in urban dining systems. Access to dining options is a key concern for urbanites as is, increasingly, sustainable options. This study finds dining options in the Tokyo Metropolis area clustered around railway stations and with millions of such passengers with no access to sustainable dining options.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 5","pages":"387-399"},"PeriodicalIF":0.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This spread of low-density, discontinuous urban development brings with it important social and environmental challenges. Despite these issues, people continue to migrate to these often-named peri-urban areas, even though the migration of large numbers of people irreversibly transforms the very qualities that initially drew them into these spaces. This study contributes to the understanding of the role of cognitive and emotional factors in neighborhood preferences. Here, using cognitive psychology experiments with state-of-the-art immersive 360° stimuli simulations of neighborhood scenes, we reveal that preferences for peri-urban neighborhoods are significantly lower than for urban and rural environments. Notably, stimuli-directed emotional signals clearly supersede cognitive evaluations of neighborhood characteristics. These findings emphasize the need for aligning available housing options with individuals’ emotions to foster place attachment and encourage active community engagement in shaping their neighborhoods. As urbanization increases, people often flock to the outskirts of expanding cities. Using immersive simulations of neighborhoods, this study finds that people prefer such peri-urban neighborhoods less than rural or urban environments.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 5","pages":"447-459"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44284-025-00232-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123599","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, insufficient analysis of their effectiveness has weakened the design of pollution controls. In this study, we analyzed the impact of short-term controls on nitrogen oxide emissions and quantified their main drivers in both the host and neighboring cities of 11 events held in east China from 2010 to 2023. We found that short-term controls might be more effective in neighboring cities than in host cities for some events, and that their benefits in terms of reduced emissions have weakened over time. Furthermore, the main sector of emission abatement for events has shifted from power to industry and transportation, reflecting the evolution of emission controls and the relative dominance of air-pollution budgets for different sectors. Our analysis highlights the enhanced targeting of short-term air pollution controls for Chinese cities, which also supports the long-term policy design. For major events in China, such as the Olympic Games, air-pollution emission controls have been imposed in the host and neighboring cities to enhance the experience and reduce health risks. This study reveals the varying effectiveness of short-term emission controls between host and neighboring cities, showing weakening benefits over time as cities learned from past event-hosting experiences.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 5","pages":"434-446"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assembled administrative boundaries, locations of health facilities, socio-economic indicators, road networks, land cover features and travel speeds. Using a least-cost path algorithm, we computed travel times to the nearest childbirth care facility by type and ownership (public and private). We measured the percentage of women of childbearing age (WoCBA) living within 15, 30 and 60 minutes of their nearest facility and its variation by socio-economic status. On average, travel speeds ranged from 14 to 28 km h−1. Travel to any facility required an average of 8 minutes, increasing to 22 minutes for public hospitals, with notable variation across communes. While nearly all WoCBA (100%) lived within 30 minutes of any facility, coverage dropped to 82% for public hospitals. Traffic congestion substantially increased travel time and reduced coverage. Our findings reveal disparities favoring wealthier women, particularly in peri-urban communes with longer average travel times. Targeted interventions, such as building new roads and enhancing public transportation, are needed in peri-urban areas to improve access to and equity in childbirth care.

China has initiated a range of urban greening policies to increase the number of urban trees, but monitoring urban tree dynamics at a national scale has proven challenging. Here, we used high-resolution nanosatellite images to quantify urban tree cover in all major Chinese cities in 2019 and study changes in tree cover between 2010 and 2019. We show that 11.47% of urban areas were covered by trees in 2019, and 76% of the cities experienced an increase in tree cover compared with 2010. Notably, the increase in tree cover in the mega-cities of Shanghai, Beijing, Shenzhen and Guangzhou (6.64%) was higher than that in other cities analyzed. Tree cover increases also vary between urban land use types, with public service (3.09%) and residential areas (1.79%) having the highest values. The study employed a data-driven approach toward assessing urban tree cover changes, showing clear signs of overall increases that nonetheless do not benefit all cities equally. Trees enrich cities, contributing to urban ecosystems and to the health of urban populations. This study quantifies urban tree coverage in all major Chinese cities, finding that greening efforts are successful but that certain mega-cities are benefiting more.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 5","pages":"460-469"},"PeriodicalIF":0.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To bridge the gap between the understanding of local interventions and global climate goals, we call for the strengthening of assessment tools such as urban typologies, case study synthesis and big geospatial data studies. We sort research gaps into five overarching themes: (1) urban form, (2) data and artificial intelligence, (3) policies and governance, (4) system transformation and (5) potentials, costs and losses. Using these methods for categorizing and analyzing cities based on shared characteristics will enable the tailoring and scaling of local climate solutions to global contexts. Urban climate action is essential generally and is in the spotlight given the upcoming IPCC focus.
