To assess whether climate and disaster risks can have an impact on coastal systems
Local and regional climates are changing and affecting temperature, precipitation, and wind patterns. These changes may lead to:
- Increasing intensity of tropical cyclones.
- Changes in the rate of sea level rise and intensity of storm surges.
- Changes in averages and extremes in temperature and precipitation.
- Increased vulnerability in areas where there is additional risk associated with other geophysical hazards including earthquakes, tsunamis, landslides, and volcanic eruptions.
This tool therefore screens at the initial stages of a project development for risk from both climate and geophysical hazards.
To assess how these risks could affect development
The impacts of climate-related and other natural disasters make development more challenging. For coastal communities, these challenges may include:
- Damage to infrastructure services, such as water and sanitation.
- Degradation of natural resources that support coastal livelihoods and provide protection.
To assess how the development context could modulate risks
In addition, the development context can influence the level of impacts caused by climate-related and other natural disasters. Social, political, and economic factors-such as access to finance and social safety nets-are important to consider in evaluating the relationship between development plans and risks.
To design climate- and disaster-resilient projects
Impacts from climate change and disasters can undermine the benefits of development. Addressing these risks during project design can therefore help protect and ensure sustainability of project investments. For example:
- Engineers can design flood protection structures to tolerate higher storm surges or sea level rise in addition to earthquakes in areas considered of high risk.
- Planners can develop zoning regulations to reduce or prevent infrastructure development in the most vulnerable coastal areas.
