The HydroHazards project explores locations, sectors, and vital societal functions exposed to multiple hydrometeorological events. The project devises methods and tools to assess the cascading effects that multiple events may have upon critical infrastructures and social groups. This brief provides an overview of these methods and tools and a summary of their application in a Swedish case study.
Much of the existing assessments of climate change impacts are large-scale simulations. Small- and local-scale assessments are necessary for nuanced understanding of possible impacts of multiple hazards on society. This view is needed for supporting local adaptation strategy and planning. At the same time, societies’ dependency on critical infrastructure and vital societal services is increasing, due to growing system complexity and interconnectedness. Together, these shifts are likely to increase societal vulnerability and impact adaptive capacity.
In response to this need, HydroHazards zooms into the municipality of Halmstad to explore the likelihood of multiple hydrometeorological (i.e., water and weather) events occurring sequentially or in the same location. Furthermore, we investigate the effects that climate change may have on the intensity and frequency of multiple hazards by focusing on extreme – low likelihood but high impact – events. Lastly, we look at the cascading or so-called domino effects on critical infrastructures and vital societal services and how these effects may cause new social vulnerabilities.

Project / The project will examine how exposure and vulnerability to multiple water hazards lead to different types of impacts on infrastructures and populations.
Press release / A tool, which is helping to monitor decarbonization in the cement industry, has now been expanded to include the production of calcined clays – a key cement decarbonization solution.
Feature / To remain a leader in climate policy, the EU must tackle emissions produced beyond its borders, which result from the EU’s demand for imported goods.
Project / C-SINK aims to transform the CDR market in Europe, focusing on innovation and sustainability to achieve net negative CO2 emissions.
