Abstract
Adaptive management is an elegant concept. Structure management interventions and policies as experiments, monitor feedback, and make necessary adjustments. Yet, the implementation of adaptive management has often been difficult, and the outcomes unclear. We examine in this chapter six issues or concepts that emerge as central to ongoing efforts to advance the theory and practice of adaptive management of natural resources: (1) adopting a transdisciplinary perspective on adaptive management; (2) shifting from a natural resource management to social-ecological systems perspective; (3) situating adaptive management within a governance context; (4) surfacing the role of power in adaptive management processes; (5) engaging with knowledge co-production; and (6) exploring the role of adaptive management as a deliberative tool in support of social-ecological transformations.
