Book excerpt: Although humans desire stability in our lives to help us understand the world and survive, nothing in nature is permanently stable. How can society anticipate and adjust to the changes we see around us? Scientists use panarchy theory to understand how systems--whether forests, electrical grids, agriculture, coastal surges, public health, or human economies and governance--interact together in unpredictable ways. Applied Panarchy, the much-anticipated successor to Lance Gunderson and C.S. Holling's seminal 2002 volume Panarchy, documents the extraordinary advances in interdisciplinary panarchy scholarship and applications over the past two decades. Intended as a text for graduate courses in environmental sciences and related fields, Applied Panarchy picks up where Panarchy left off, inspiring new generations of scholars, researchers, and professionals to put its ideas to work in practical ways.
