Cities can benefit from complex supply chains

"Longstanding research has found that if supply chains get too complex, they can become problematic," said corresponding author Alfonso Mejia, associate professor of civil and environmental engineering. "But the opposite tends to be true in nature: In ecological systems, there is a well-known connection between complexity and resiliency."
Diversity increases complexity, which is a good thing in nature, Mejia said. The diversity of an ecosystem -- having many species that can do various tasks -- makes that system less vulnerable in the face of wildfires, floods and other natural disasters.
