As populations steadily increase in cities, the world's natural resources are consumed at ever-faster rates. The majority of the world's populations live in countries where clean water supplies are dwindling, and these water shortages are also quickly translating into food shortages. What can designers do to avert looming water-related realities? UrbanLab: Bowling views potential water crises as opportunities to speculate on future urban design possibilities, especially in cities. Several projects are presented that take an ecological approach to re-thinking received urban design methodologies of addressing the design of water-related infrastructures in existing and new cities.
