A number of other sections in the site follow-on naturally from a consideration of resilience. Two useful tools for resilience-building in complex socio-ecological systems are structured scenarios and adaptation and adaptive management. People use scenarios to envision alternative futures and the pathways by which they might be reached. By envisioning a range of alternative futures and actions that might achieve or avoid certain outcomes, communities can identify and choose resilience-building policies. Active adaptive management can be used as an approach that views policy as a set of experiments designed to reveal processes that build or sustain resilience. It requires, and facilitates, a social context with flexible and open institutions and multi-level governance systems that allows for social learning.
