Few phenomena make the case for adaptive ecosystem management quite as well as climate change, the hydrological effects of which will upset settled expectations and require water institutions to adapt. The effects of climate change will be felt at multiple hydrological, geographic, and institutional scales that transcend specific water sources or political and legal jurisdictions. Moreover, the effects will be uncertain, complex, and frequently changing. Thus, water resources should be managed at watershed scales, and this management should use the adaptive management methods of flexibility, experimentation, and learning through iterative processes of managing environmental conditions and programs.
However, the adaptive ecosystem management concept has had the unfortunate effect of de-emphasizing or even rejecting the role of planning in shaping the relationships between human actions and ecological conditions. Too little attention has been given to the role of planning in adaptation and ecosystem management. A concept of "adaptive planning" is not only consistent with adaptive ecosystem management, but could actually improve adaptive ecosystem management methods and the capacity of institutions to engage in adaptive ecosystem management effectively. Moreover, a growing number of watershed plans are exhibiting some characteristics of adaptive planning, particularly with respect to the effects of climate change on watersheds and water resources.
This article explores the role of adaptive watershed planning in adapting to climate change. Adaptive watershed management requires the use of adaptive planning methods, not merely ad hoc, reactive experimentalism and incrementalism. Without some process of planning, Charles Lindblom's "science of muddling through" becomes "the science of drifting along." Adaptive planning gives some direction and focus to adaptive ecosystem management activities. Furthermore, adaptive watershed planning can improve not only adaptive watershed management methods, but also the content and effectiveness of watershed plans themselves. If watershed plans are to be useful, they must contemplate the uncertainties associated with climate change and its effects.
In addition to describing the theory and features of adaptive planning and applying adaptive planning principles to watershed planning and management, this article also explores examples of watershed plans in the U.S. and Canada that have addressed climate change and analyzes a number of issues in adaptive watershed planning, including barriers to, and opportunities for, the increased and improved use of adaptive watershed planning to improve the capacity of watershed institutions to adapt to climate change.
