C.S. Holling
Canadian ecologist (1930–2019) whose adaptive cycle, panarchy, and resilience framework reshaped how complex adaptive systems are understood across ecology, economics, and governance.
Crawford Stanley Holling (1930–2019) was a Canadian ecologist whose empirical work on predator-prey dynamics, forest ecosystems, and systems under stress produced theoretical frameworks that have reshaped fields far beyond ecology. His 1973 paper 'Resilience and Stability of Ecological Systems' drew the distinction between engineering resilience and ecological resilience that now informs thinking from urban planning to public health. With Lance Gunderson he developed the adaptive cycle and panarchy in the 2002 volume that gave the framework its name. He founded the Resilience Alliance and spent his later years warning that rising global connectivity was increasing the risk of cascading systemic collapse — a warning that the AI transition has vindicated with uncomfortable precision.

Holling's method was distinctive: he grounded theoretical frameworks in extended empirical engagement with specific ecosystems. The spruce budworm dynamics of New Brunswick forests. The grassland complexity of the Serengeti. The North Atlantic fisheries whose collapse his models anticipated better than the official management models did. The adaptive cycle was not theorized
