The novelty of this qualitative systematic review is that it includes policy documents and reports as well as academic papers to interrogate the state of both smart city knowledge and smart city practice in the region. The review identified five research themes, namely, (1) the social development promises of the smart city, (2) institutionalizing smart city governance, (3) smart cities and digital citizenship, (4) smart city (as) infrastructure and (5) approaches to ‘smarting’ the city. The study shows that, for a comprehensive agenda on smart city research, more attention should be given to smart city projects and the impacts of digitalization and datafication, but it also finds that more considered local and governance-oriented lenses for such agendas are necessary if they are to be relevant to the Southern African Development Community region. This study is a systematic review that combines both academic and policy sources to assess the state of smart cities in the Southern African Development Community. It found five major themes that call for a more nuanced approach to smart city governance that accounts for local variations.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 2","pages":"149-156"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555220","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}

However, how, or to what extent, a warming climate will impact urban fire frequency remains unknown. Here we quantify the shift in the frequency of various urban fire incident types in response to a warming climate using a global fire incidents database collected from 2,847 cities. We find that the frequency of building fires increases quadratically, and the minimum occurs at thermal comfort temperature (that is, around 24.0 °C), while for every 1 °C increase in air temperature, the frequencies of vehicle and outdoor fires increase by (2.5 ± 0.8)% (mean ± standard error) and (4.7 ± 2.2)%, respectively. In the SSP5-8.5 scenario by 2100, we project that building fire frequencies could decrease by (4.6 ± 1.1)%, while vehicle and outdoor fires could increase by (11.6 ± 3.7)% and (22.2 ± 10.2)%, respectively. These findings can guide the development of climate-resilient strategies by providing quantitative advice on allocating and reallocating budgets for national fire services across cities. Although urban fire incidents cause enormous casualties due to dense population concentrations, the risks from these incidents under a warming climate remain unknown. This study analyzed a global database of urban fire incidents to quantify and predict changes in the frequency of various urban fire incident types in response to a warming climate, finding general increases in fire frequency.","PeriodicalId":501700,"journal":{"name":"Nature Cities","volume":"2 3","pages":"254-264"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668475","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}
