Fig. 2. Coastal Zone System Information Feedback Loops (CZFBL).
The default loop is shown as the green arrows, and the purple, dashed arrows represent the SAF augmentation of loop. The ESE Assessment box represents the major part of the SAF methodology, which links the assessments of the three ESE dimensions. The default loop is slow in forcing policy to react to problems, many of which become irreversible, while the SAF loop provides quick access to policy makers and the public with objective information on how the CZS responds to changes. When this loop is maintained, it can provide prognostic scenario simulations that allow policy to be precautionary regarding emerging problems, including the efficacy of policy directives. The small diamond boxes represent critical threshold constraints on the interactions between components of the system that need to be properly represented for successful forecasting of policy scenarios.
