                               Adaptation Pathways and their benefits

 Developing and implementing a coastal hazards adaptation plan requires a responsive, flexible,
 and long-term approach that considers the effectiveness, acceptability, and consequences of a
 range of responses. For Noosa, the ability to maintain the look and functionality of our current
 beachfront and river foreshore areas is likely to become increasingly difficult due to increasing
 coastal hazard risks. Utilising an adaptation pathways approach allows Council and the
 community to understand, plan for, prioritise, and appropriately sequence adaptation options.

 A pathways approach responds to changes in coastal hazard risks by using trigger points to
 indicate when a preferred action or set of actions is likely to be implemented. A trigger can be
 based on one or more of three things:

     -   Environmental conditions (e.g. sea levels have risen to a certain point)
     -   Public asset functionality (e.g. an asset can longer function to an acceptable standard)
     -   Community tolerance (e.g. the interruptions to lifestyle are no longer acceptable).


 The illustrative graph below (Figure 11) shows the benefits of adopting an adaptation pathways
 approach in reducing risks. Without a response, the risks from coastal hazards for Noosa are
 likely to rise and become intolerable in many locations.
