Who should use this tool?
Development practitioners and Task Team Leaders designing projects in coastal areas.
What does this tool do?
The tool serves as a self-paced guide for practicing due diligence during project design.
Specifically, it guides users through a high-level screening of projects for risks from climate and geophysical hazards. Using this tool will help ensure project teams that they have considered what potential effects climate change and natural disasters could have on a project.
The greatest value of the tool is that it provides a structured and systematic process for understanding climate and disaster risks. The actual risk ratings themselves, while instructive, should inform further consultations and dialogue, and help determine the appropriate level of effort for further studies during project design. The tool does not provide a detailed risk analysis, nor does it suggest specific options for making a project more resilient.
When should this tool be used?
The tool should be used at an early “concept” stage of project development.
Note that a good understanding of the project location and components is required. The tool can be revisited if a project is modified or additional information is acquired.
This tool is a form of due diligence. It does not review needs or recommend solutions in sufficient detail for input into project design.
Which aspect of project components can the tool address?
This tool addresses risks to both built defenses, such as sea walls, and natural defenses, such as conservation of beaches and mangrove ecosystems. In addition to such physical defenses, it also considers non-physical factors that affect flood risk, such as policies, zoning regulations, and conservation measures.
What if climate change and disasters have already been considered in project design?
If your project team has already designed measures to reduce risks from climate and disasters, use of this tool is still recommended. It helps ensure that a broad range of hazards are considered, including some that might not have been identified earlier. The project team should then be sure the risk ratings they apply in the tool reflect the measures they have already designed.
For example, if a project team is already planning to build a sea wall higher to protect from sea level rise, the tool rating of potential impact should be lower than if the team did not plan to build that way. Whenever a potential impact rating is revised downwards for this reason, the teams using the tool could include explanatory notes to clarify this and validate ratings with others reviewing the screening.
