Cities already generate more than 60% of global GDP, 600 urban centers hold over a quarter of the population, and over 500 cities exceed 1 million residents, so the claim is that urban systems need macro, interdisciplinary solutions. Projects include Roadmap 2050 (consortium of 13 firms proposing an 80% carbon reduction by 2050 with technical, financial and policy measures), a Moscow plan that reorganizes land-use after a 2.5× border expansion to preserve informal economies and retrofit transport, and a HUD Rebuild by Design bid using Dutch water expertise to target maximum-impact flood zones.
