Building resilience to climate and geophysical hazards is a vital step in the fight against poverty. Screening for risks from these hazards improves the likelihood and longevity of a project’s success. Screening enables project teams:
- To assess whether climate and disaster risks can have an impact on roads
- To assess how these risks could affect development
- To assess how the development context could modulate risks
- To design climate- and disaster-resilient projects
To assess whether climate and disaster risks can have an impact on roads
Local and regional climates are changing and affecting temperature, precipitation, and wind patterns. These changes may lead to:
- More frequent or intense extreme weather events that can damage road infrastructure, such as floods and heat waves.
- Sea level rise, which can inundate low-lying roads.
- Changes in the intensity and frequency of tropical cyclones that damage bridges, tunnels, and other coastal infrastructure.
There are also natural hazards unrelated to climate, including earthquakes, tsunamis, landslides, and volcanic eruptions. This tool screens for risks from both climate hazards and these geophysical hazards.
To assess how these risks could affect development
The impacts of climate-related and other natural disasters make development more challenging. Many of the world's poorest may have to face additional hurdles, such as difficulty accessing markets, hospitals, or schools due to the impacts of climate and disasters on roads and road infrastructure.
To assess how the development context could modulate risks
In addition, the development context can influence the level of impacts caused by climate and disasters. Social, political, and economic factors, such as access to savings or loans, are important to consider in evaluating the relationship between development and climate and natural disasters.
To design climate- and disaster-resilient projects
Impacts from climate change and disasters can also undermine the benefits of development. Addressing these risks during project design can therefore help protect project investments. For example:
- Engineers can select materials capable of withstanding a wider range of temperatures.
- Planners can identify less vulnerable locations.
- Designers can develop natural and engineered protective measures to reduce the impacts from increased levels of precipitation.
