However, most existing studies focus on RPV’s technical or economic potential often overlook real-world electricity consumption and regulatory constraints that shape actual deployment. Here we assess the deployable potential of RPV across 367 Chinese cities by incorporating variations in building types, regional characteristics and policy limitations. Our findings reveal that only 42% of the national technical potential is realistically deployable. In particular, accounting for regulatory factors shifts the focus of RPV deployment from rural areas to urban public and industrial buildings, and from western to northern and central regions. To maximize value, initial deployment should prioritize public and industrial buildings in central and southern cities. These insights provide actionable guidance for shaping effective RPV development pathways aligned with China’s ambitious deployment targets. This study moves beyond technical estimates to assess the deployable rooftop solar potential across 367 Chinese cities, factoring in real-world constraints. The findings offer actionable insights to guide strategic deployment and support China’s ambitious solar energy goals.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 7","pages":"650-661"},"PeriodicalIF":0.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123501","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}

Growth in PT accessibility can mask wide variation near and within even major cities. Contrary to the 2023 SDG report’s claim of over 80% convenient PT access in major Chinese cities, we find that only two cities’ villages meet the benchmarks and lowest rate, at just 34%. Commute time improvements depend heavily on population dynamics, but new bus station placements often fail to reflect these shifts. Meanwhile, although fares to city centers generally decreased, the proportion of village populations covered by high-fare routes rose noticeably in some cities. These results reveal how additional travel time, higher costs and changing demographics can impede villagers’ access to urban services. The narrow focus on a ‘10-minute’ performance metric risks driving suboptimal planning decisions that overlook broader travel burdens. A more nuanced, population-responsive approach to planning is needed to ensure that SDG 11 remains inclusive for all urban communities. As China’s cities grow, getting around town must keep pace. This study finds wide disparities in public transport accessibility in villages near and within major Chinese cities, suggesting the limitations of focusing on overall commute times.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 8","pages":"749-758"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123727","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}

Classic theories, such as egocentric activity spaces and central place theory, provide crucial insights into specific facets of movement, including home-centricity and hierarchical spatial organization. However, identifying universal characteristics or an underlying principle that quantitatively links these disparate perspectives has remained a challenge. Here we reveal such a connection by analyzing the spatial structure of individual daily mobility trajectories using network-based modules. We discover a universal scaling law: the spatial extent (radius) of these mobility modules expands sublinearly with increasing distance from home, a pattern consistent across three orders of magnitude. Furthermore, we demonstrate that these modules precisely map onto the nested hierarchy of urban systems, corresponding to local, city-level and regional scales as distance from home increases. These findings deepen our understanding of human mobility dynamics and demonstrate the profound connection between classical urban theory, human geography and mobility studies. Urban space forms nested hierarchies: neighborhoods are embedded within cities, which in turn are part of larger regions. This study finds that as individuals travel farther from home, they explore decreasingly larger areas around their new locations.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 7","pages":"603-607"},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123413","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}

Few studies have comprehensively investigated the flood exposure faced by vulnerable communities in the Global South, where pervasive slums present a major challenge to inclusive urban planning and flood management. Here, combining advanced machine learning techniques and publicly available satellite images, we identify hot spots of urban slum populations in floodplains in the Global South and examine their settlement patterns. We find that approximately one in three people living in slums in the Global South resides in a floodplain. Slum dwellers are 32% more likely to settle in floodplains compared with residents in adequate housing. The concentration of slum populations is particularly high in areas that have experienced severe floods. These data-driven insights highlight the disproportionate flood exposure faced by slum dwellers in the Global South and underscore the need for just and equitable flood adaptation management. Flooding is a growing challenge in many cities worldwide. Using satellite images, this study finds that slum dwellers in the Global South are more likely to settle in floodplains, especially in recently flooded areas.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 7","pages":"626-638"},"PeriodicalIF":0.0,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123495","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}

Traditionally, biological urban evolutionary research has focused on physical factors such as habitat fragmentation, pollution and resource availability, often overlooking the social and political forces shaping urban environments. This Review explores how religion, politics and war drive urban wildlife evolution by shaping environmental conditions and selective pressures. We synthesize existing knowledge on these influences and propose testable hypotheses to advance the field. Understanding these dynamics is essential for explaining the variability in urban evolutionary processes and predicting the future development of urban systems. By integrating social and political dimensions, we can gain deeper insights into how cities shape the evolution of organisms that inhabit them. Cities affect biological evolution, but traditionally researchers focus on the biophysical influence of urban environments. Instead, this Review explores how the social processes of religion, politics and war drive wildlife evolution by shaping urban conditions.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 7","pages":"593-602"},"PeriodicalIF":0.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123503","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}
