How can scenario-driven investment decisions improve resilience in coastal facilities?

• A. By evaluating capital expenditure under different hazard futures, ensuring that investments target the most likely, severe, and costly outcomes.
• B. By only considering historical averages.
• C. By ignoring hazard futures.
• D. By focusing solely on aesthetics.

Answer: (A)

Considering a range of plausible hazard futures helps guide capital decisions so a coastal facility remains functional and affordable across different possible futures. By testing investments against multiple scenarios—different sea levels, storm intensities, flood frequencies, and other hazard drivers—planners can see how a project performs under each condition and prioritize actions that reduce risk across the spectrum. This tends to emphasize investments that address the most likely events as well as the severe, high-cost outcomes, rather than relying on a single forecast or historical data. It also avoids underestimating risk due to non-stationary climate conditions. Ignoring hazard futures or focusing only on aesthetics would leave the facility vulnerable to extreme events or misallocate resources, respectively.
