In this fourth and final stage, users integrate their assessments of potential impact and adaptive capacity to arrive at a rating for overall project risk.
Separation of risks by sector and subsector: This step is organized by sector and subsector for several reasons. First, each sector or subsector is subject to different potential impacts, so the ratings need to be differentiated. Second, the activities of each sector and subsector may have different levels of influence on the overall project outcome. Potential impacts in one sector or subsector might not directly impair the intended service of the project, whereas potential impacts to activities in another sector or subsector of the same project could disproportionately affect the project.
For example, suppose a project focuses on building schools and also includes construction of some ICT infrastructure for their use. Impacts from climate and geophysical hazards on the school buildings are likely to affect the project outcome more strongly than any impacts on the ICT infrastructure.
Risk ratings: The risk ratings are done separately for the Historical/Current and Future time frames in order to account for possible changes in potential impact over time.
The rating scale for project risk looks like this:
|Insufficient Understanding||No Risk||Low Risk||Moderate Risk||High Risk|
The results of each step and the overall results are summarized in tables and presented as a final PDF report for the user. The results of this screening are not sufficient to serve as the basis for decisions regarding detailed project design. Rather, the results flag potential impacts and risks from climate and geophysical hazards that may need closer attention during project preparation through further studies, consultation, and dialogue.
