In Sweden the rescue services responds toon average 5000 annual incidents of wildfires. Most of these are small and during the last 200 years the annual burnt area have decreased by about 99 %. However, societal and climatic trends indicate that complicated incidents are becoming more frequent in the near future.
The research at RISE focuses on risk and danger models for the spread and ignition of wildfires, on ignition of structures from wildfires and on the preparedness and response to large wildfire incidents.
Intensity and spread rates for Swedish forests are summarised in a short paper which will be presented at the IX International Conference on Forest Fire Research, Coimbra (November, 2022).
Popular scientific radio shows on Swedish wildfires.
Garden structure is critical for building survival in Swedish forest fires. New publication in Safety Science describes that a managed lawn, deciduous trees around the garden and little fuel agaist the facade are teh most important factor for buildings to survive Swedish forest fires.
New fuel models for Swedish forest landscapes. RISE and SLU have mapped fuel structure and composition in Sweden. There is a Swedish report here and fuel models to download to the right.
Overview of wildfires in Sweden. RISE and SLU have assessed recent trends and patterns of wildfires during recent decades in a report published 2020, on behalf of the Swedish Civil Contingency Agency (MSB). The large incidents recent years are not only a consequence of exceptional weather leading to high fire danger but also societal trends in the response to fires, resource distribution, land use practices and strategies.
RISE and the Mid University of Sweden studied the inclusion of different types of volunteers in the response to the 2014 Västmanland fire
Forestry machinery have initiated a number of the high impact fires in Sweden during recent decades even though they account for only a fraction of all wildfires. The characteristic of these type of fires are analysed and can be found here: Swedish, English.
TREEADS. RISE Fire Research AS in Trondheim coordinates one of the largest wildfire projects ever launched in Europe, financed by the Commissions new Green Deal. For info, contact Ragni Mikalsen or Kemal Arsava
Landscape management in the WUI. Rise works with Mid Sweden University and SLU in Uppsala and Umeå to find barriers and solutions for management of the wildland Urban interface that will benefit communities in a changing climat. The project is funded by FORMAS.
