Stage 4: Identify Solutions

Share This Article

Learn how to identify the most effective options for your context with these steps in this stage:

  • Primer: Understand available measures 
  • Step 4.1 | Confirm & classify objectives
  • Step 4.2 | Explore feasible measures
  • Step 4.3 | Screen for suitability
  • Step 4.4 | Develop options
  • Step 4.5 | Develop scenarios
  • Step 4.6 | Estimate benefits and costs
  • Step 4.7 | Compare options
  • Step 4.8 | Check for sustainability
  • Step 4.9 | Decide on and refine your solution

With the results of your assessment, you now have the information to identify solutions and decide on the most promising combinations to reach your objective. Take your time and work through the steps with your steering committee. Gather more data if you identify gaps. Identify the most sustainable and effective solution by following the nine steps in the path laid out in this chapter.

Before starting off, let's clarify four terms:

  • Measure: refers to an individual action item, for example, the afforestation of mangroves or the rehabilitation of reefs.
  • Option: the combination of different measures in a package. This may include green and gray structural measures as well as non-structural ones (e.g. improved evacuation systems).
  • Scenario: a projection of future conditions over a given timeframe. These will be used to test the effectiveness of options under different assumptions.
  • Solution: the eventual option you decide on. The solution should ideally be based on the best performance in terms of sustainability and effectiveness.

Principles & tips

  • Keep the steering committee at the heart of the process and ensure that suggested solutions are reviewed and agreed upon by the wider community and group of stakeholders. Keep everyone on board! 
  • Explore and understand the various measures well. You may want to read the step-by-step guides in appendix A.
  • Focus on non-structural measures first, then add green and/or gray structural measures.
  • Use the interactive solution finder as your virtual assistant, but make sure that technical experts review the ranking of solutions and support decision-making.
  • Ensure that the eventual suite of solutions can be reasonably expected to reach your objective.
  • If there are limitations (e.g. funding), consider a phased approach. Focus on what you can do now and add more aspects later on.
