Lance Gunderson is a Professor and Chair of the Department of Environmental Sciences at Emory University in Atlanta, GA. He and CS "Buzz" Holling coined the term "Panarchy" in their 1995 edited volume Barriers and Bridges to the Renewal of Ecosystems and Institutions. They used the word to title another edited volume in 2002, Panarchy: Understanding Transformations in Systems of Humans and Nature.
Ecological resilience provides a theoretical foundation for understanding how complex systems adapt to and recover from localized disturbances like hurricanes, fires, pest outbreaks, and floods, as well as large-scale perturbations such as climate change. Ecologists have developed resilience theory over the past three decades in an effort to explain surprising and nonlinear dynamics of complex adaptive systems.
Scientists and researchers concerned with the behavior of large ecosystems have focused in recent years on the concept of "resilience." Traditional perspectives held that ecological systems exist close to a steady state and resilience is the ability of the system to return rapidly to that state following perturbation. However beginning with the work of C. S.
‘Panarchy’ is a new term coined from the name of the Greek god Pan, a symbol of universal nature and associated with unpredictable change. It represents an alternative framework for managing the issues that emerge from the interaction between people and nature. That interaction generates countless surprises, often the result of slow changes that can accumulate and unexpectedly flip an ecosystem or an economy into a qualitatively different state. That state may be not only impoverished, but also effectively irreversible.
Creating institutions to meet the challenge of sustainability is arguably the most important task confronting society; it is also dauntingly complex. Ecological, economic, and social elements all play a role, but despite ongoing efforts, researchers have yet to succeed in integrating the various disciplines in a way that gives adequate representation to the insights of each.
Panarchy, a term devised to describe evolving hierarchical systems with multiple interrelated elements, offers an important new framework for understanding and resolving this dilemma.
