Estudio Teddy Cruz + Fonna Forman forwards the San Diego–Tijuana border region as a global laboratory for engaging the central challenges of urbanization today: deepening social and economic inequality, dramatic migratory shifts, urban informality, climate change, the thickening of border walls and the decline of public thinking. The projects and initiatives presented here mobilize design and political thinking to confront homogenization and exclusion in the city, building diverse social and spatial programs for cross-border interdependence.
