The shape of urbanism in the next century is the largest physical project our species will undertake. This is what it might look like. ### Slide 2: The urban century, in numbers - § Vital signs - Urban share · 2024 - ~57 % - UN DESA Population Division - Urban share · 2050 - ~68 % - ~2.5B added to cities, mostly Asia & Africa - Megacities (10M+) · 2024 - ~50 by 2035 - Cities >1M in Africa · 2050 - ~150 - From ~80 today; Lagos, Kinshasa, Dar es Salaam fastest ### Slide 3: Carlos Moreno's small idea - §1 · The 15-minute city - Carlos Moreno (Sorbonne, 2016) proposed the ville du quart d'heure: a city where work, school, healthcare, groceries, parks, and culture are within a 15-minute walk or bike ride. Anne Hidalgo's Paris adopted it as policy in 2020. Melbourne (20-minute), Portland, Bogotá, Milan have analogous frames. - Why it works - Reduces car dependency without banning cars - Higher street life → lower retail vacancy - Climate co-benefit: ~30% reduction in transport emissions in implementing arrondissements - Counter-intuitive equity gain — when paired with rent stabilization - forecast Most North American downtowns will adopt some 15-minute-city language by 2030; whether the zoning follows is the open question. - Photo · the policy is mostly about taking lanes back from cars. ### Slide 4: What is reachable in 15 minutes - §2 · Diagram · 15-min schematic - After Carlos Moreno, Sorbonne IAE, "The 15-Minute City". ### Slide 5: What "smart" actually delivers - §3 · Smart city, sober view - The 2010s smart-city wave (Songdo, Masdar, Toronto Quayside) made big promises and delivered modest results. Toronto Quayside collapsed in 2020 under privacy concerns; Masdar built only ~5% of plan; Songdo's occupancy stagnated. The 2020s lesson: digital twins and IoT are infrastructure, not outcomes. - ProjectLocaleStatus · 2026Lesson - Songdo IBDSouth KoreaBuilt; ~70% occupiedYou can't build culture top-down - Masdar CityUAE~5% built; pivoted to test-bedClimate goals, scale missed - Sidewalk TorontoCanadaCancelled 2020Data governance is a city problem - The Line · NEOMSaudi ArabiaMassively descoped (2024)Linear cities don't pencil - TelosaUSA · proposedConcept renderings onlyRenderings are not housing - Helsinki / Amsterdam open dataEUBoring, workingQuiet wins compound ### Slide 6: Where the population goes - §4 · Megacities - The next thirty years of urbanization happen in Africa and South Asia. Lagos will pass 30 million; Dhaka, Karachi, Kinshasa close behind. Western megacities (Tokyo, NY, LA) plateau or shrink. The infrastructure question is not "how do we build a smart city in Stockholm" — it is "how does Lagos house 10 million more people while running on a 70-year-old grid". - Lagos · 2024 - ~16 M - ~30 M projected by 2050. Informal economy >50%. - Tokyo · 2024 - ~37 M - Plateau · expected to shrink to ~33 M by 2050. - Dhaka · 2024 - ~23 M - Densest megacity on Earth · ~46k/km². ### Slide 7: Build up, build green - §5 · Vertical urbanism - Vertical farms (AeroFarms, Plenty, Infarm), green facades (Bosco Verticale, Milan, 2014), and mixed-use towers continue to evolve. The economics of vertical farming have struggled — Plenty filed Chapter 11 in 2025 — but specific crops (leafy greens, soft fruit, pharmaceutical botanicals) remain viable. The bigger urban bet is mass-timber towers (Mjøstårnet, Norway, 85.4 m, 2019; Ascent, Milwaukee, 86.6 m, 2022). - Mass timber by the numbers - ~25% lower embodied carbon than reinforced concrete (forest-managed, conservative LCA) - 4–6× faster construction at mid-rise scale - Code allows 18 storeys in IBC 2021 (US); higher in Norway, Austria, Canada - Insurance & lender resistance softening 2023–25 ### Slide 8: Working with water - §6 · Sponge cities - Yu Kongjian's sponge city framework (Chinese MOHURD, 2014) treats stormwater as an asset, not waste. Permeable pavement, bioswales, green roofs, restored wetlands. Pilots in 30 Chinese cities; New York's Bluebelt, Copenhagen's cloudburst plan, Rotterdam's water plazas, Singapore's PUB ABC Waters parallel. - Why it matters - Climate-adaptive: handles intensifying precipitation - Heat-island reduction (vegetation cools 2–4 °C locally) - Biodiversity uplift; mental-health co-benefits - Cheaper retrofit than gray-infrastructure expansion ### Slide 9: Beyond cars - §7 · Mobility - Mode2026 statusPromiseCaveat - E-bikes~50M sold/yr globallyQuiet revolution; replaces 30%+ of urban car trips in EUBattery fires; theft - RobotaxisWaymo 250k+ paid trips/wk · May 2025Geofenced, scaling slowlyLong-tail edge cases; politics - BRTBogotá TransMilenio + ~200 citiesSubway-like service at 1/10 costRight-of-way politics - High-speed rail43k km in ChinaDecarbonizes 500–1000 km tripsUS lags structurally - eVTOLJoby, Archer, Vertical · cert phaseNice for executivesNot a mass-transit solution - HyperloopHyperloopOne shut 2023—Mostly vapour ### Slide 10: Energy and matter, in & out - §8 · Diagram · Urban metabolism - After Abel Wolman, Sci. American, 1965; Brunner & Rechberger metabolism updates. ### Slide 11: Slide 11 - §9 · Voices - "A city is not a tree." — Christopher Alexander, 1965 - Carlos Moreno15-minute city; chrono-urbanism - Janette Sadik-KhanNYC DOT 2007–13; tactical urbanism, plazas, bike lanes - Yu KongjianSponge cities; landscape ecology, Peking U. - Edward GlaeserTriumph of the City; agglomeration economics - Jane JacobsDeath and Life (1961); the founding text - Saskia SassenGlobal City; financialization & expulsions - Lloyd Alter / Brent ToderianWalkable-city advocacy; the "life-sized city" - Solarpunk movementBecky Chambers, Kim Stanley Robinson · imagined optimisms ### Slide 12: Recommended source - §10 · Watch - Not Just Bikes · "The Future We Could Have" - Toronto-to-Amsterdam ex-pat's channel on Dutch urbanism; the most efficient way to internalize what cities can be. Pair with Strong Towns' video archive. - youtube.com/@NotJustBikes → - Kurzgesagt · "The Solarpunk Future" - 10-minute primer on the optimist-pragmatist aesthetic that has eaten urban-planning Twitter. - youtube.com/@kurzgesagt → ### Slide 13: Three urban futures - §11 · 2050 scenarios - A · Solarpunk - Civic mixed-use - 15-min city is the default. Mass timber, sponge infra, robust transit. Cities decarbonize before nations. forecast - B · Splintered - Two-tier urbanism - Climate-buffered enclaves; informal settlements bear shocks. Privatized resilience. scenario - C · Drained - Coastal retreat - Multiple major cities partially abandoned (Jakarta, Miami, Alexandria). Inland boom-towns absorb. scenario ### Slide 14: Indicators · 2026–2030 - §12 · What to watch - Paris & Bogotá implementation outcomes — modal shift, retail, displacement - Nusantara (Indonesia's new capital) build-out vs Jakarta subsidence - Mass-timber tower record (likely > 100 m by 2027) - Robotaxi rides per week trajectory · Waymo, Zoox, Pony - African secondary cities receiving > $1B climate-adaptation finance - YIMBY zoning reform in US states (CA, OR, MT, MN, CT) ## Related Decks - [Asteroid Mining](https://shipslides.com/d/future-asteroid-mining) - [Autonomous Vehicles](https://shipslides.com/d/future-autonomous-vehicles) - [Brain-Computer Interfaces](https://shipslides.com/d/future-brain-computer-interfaces) - [Climate Adaptation](https://shipslides.com/d/future-climate-adaptation)
