URBANA, Ill. – The health and sustainability of cities depends, in part, on how well a city manages its food, energy, and water systems. But the flow of those key resources within a city is marked by complex interactions between these systems. Making changes or improvements to one system may cause issues for another.

Rapid population growth in the world’s urban centers calls for a greater understanding of these complex interrelationships between the systems, also known as the food-energy-water nexus (FEW).
