HazardSupport is a project 2015-2020 where SMHI and SEI (Stockholm Environment Institute) collaborate with the aim of developing a risk-based decision support for adaptation to future natural hazards. The project is funded by the Swedish Civil Contingencies Agency, MSB.

In a future climate, some extreme weather events are likely to occur more often, increasing the risk of natural hazards. For society to adapt, it needs quantitative information about the frequency and intensity of these hazards.

Through tailor-made climate effect impact studies and improved collaboration between climate experts, stakeholders and users, improved decision support for climate adaptation can be developed.

Better information about natural hazard occurrence in the future 

At present, the use of scientific knowledge is still limited when planning adaptation and implementation.

HazardSupport aims to bring together the scientific perspective with real users' knowledge and needs. An example may be an organization or individual who needs to make design level decisions regarding physical levels or thresholds such as the strength and height of a bridge.

Three case studies with identified key stakeholders


The methods are developed within three case studies with identified key stakeholders for different natural disasters:

  • Heat waves (City of Stockholm)
  • Torrential rains and floods (Karlstad and rescue services)
  • Coastal floods (Länsförsäkringar)

The project is a collaboration between SMHI and SEI (Stockholm Environment Institute).

Researchers from SMHI in the fields of climatology, hydrology, oceanography and air quality contribute to develop new and improve existing methods for climate impact analysis in each area.

SEI will introduce and improve the methods for participatory modeling, surveying stakeholders and decision-making processes.


Up to and including 2017, the project focused on the three case studies and produced materials adapted to these. During 2018, a number of activities with different types of stakeholders were carried out to present and discuss this material. In 2019, these insights will be used to produce even better support for decision-making. The experiences from 2018 user meetings improves the presentation of the results in such a way that they can be generalized and become useful to even more stakeholders.

The information material is planned to be completed by the end of 2019 in order to be disseminated to new users in 2020. Also in 2020, a number of workshops, sessions in the Norrköping decision-making arena and courses will be arranged to spread the knowledge to new users.
