Resilience in Engineered, Natural, and Water Systems

IMG_3149

The term resilience emerged in ecology during the early 1970s. At the time, researchers were debating the existence of equilibrium points in ecosystems. Equillibriums were considered stable configurations of species that an ecosystem could “evolve” (or succeed) to reach. Beyond that, little change would occur. Ecology literature accepted the existence of such system-wide, globally-stable states (Lewontin 1969). In this view of […]

Hybridization in Stormwater Infrastructure and Governance

Water infrastructure is typically about pipes and bills.  Most cities have dedicated departments that manage water distribution, sewage, and stormwater systems.  Today, however, new designs for more sustainable urban development are re-considering how we deliver these services for residents.  Rather than provide and manage water through centralized services, what are the opportunities and challenges associated […]
