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.

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.
