The Great Fire of London in 1666 produced building regulations within 2 years of the devastating blaze. Repeated flooding events along the Rhine and Danube Rivers through the late 20th century spurred zoning rules and hazard mapping that are now standard across Europe\u2019s urban planning systems. What drove these improvements was a general pathway in which disruption produced evidence, evidence generated pressure, and pressure forced modifications by agencies responsible for governing a city\u2019s well-being. However, that process has been degrading across every inhabited continent. What has emerged in its place is a volatile urbanism that is threatening resilience.<\/jats:p>","DOI":"10.1126\/science.aeh8677","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T18:02:13Z","timestamp":1783620133000},"page":"125-125","update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":0,"title":["Why cities cannot learn"],"prefix":"10.1126","volume":"393","author":[{"given":"Zaheer","family":"Allam","sequence":"first","affiliation":[{"name":"Zaheer Allam is a senior researcher at the Institute for Sustainable Futures, University of Technology Sydney, Sydney, Australia and an adjunct associate professor at the School of Architecture, Design and Planning, the University of Queensland, Brisbane, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","container-title":["Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.science.org\/doi\/pdf\/10.1126\/science.aeh8677","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T18:03:03Z","timestamp":1783620183000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.science.org\/doi\/10.1126\/science.aeh8677"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,9]]},"references-count":0,"journal-issue":{"issue":"6807","published-print":{"date-parts":[[2026,7,9]]}},"alternative-id":["10.1126\/science.aeh8677"],"URL":"https:\/\/doi.org\/10.1126\/science.aeh8677","relation":{},"ISSN":["0036-8075","1095-9203"],"issn-type":[{"value":"0036-8075","type":"print"},{"value":"1095-9203","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,9]]},"assertion":[{"value":"2026-07-09","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
