Environmental law envisions ecological systems as existing in an equilibrium state, or a “balance of nature,” reinforcing a rigid legal framework unable to absorb rapid environmental changes and innovations in sustainability. For the past three decades, “resilience theory,” which embraces uncertainty and nonlinear dynamics in complex adaptive systems, has shown itself to be a robust and invaluable basis for sound environmental management. Reforming American law to account for this knowledge is key to transitioning to sustainability. This volume features top legal and resilience scholars speaking on resilience theory and its legal applications to climate change, biodiversity, national parks, and water law.
