My PhD project aims at quantifying wildfire hazard potential for Germany. In Central Europe, wildfires are a result of climatic extreme events (drought periods and heat waves), increasing probability of ignition and flammability of vegetation. While currently wildfire hazard is managable, future climate projections give reason for concern. Wildfire hazard is estimated using simulations of fire spread, depending on climate, topography and burnable biomass (fuels). For Germany there is no spatially comprehensive fuels data set to this point. I use multi-spectral satellite imagery and LiDAR point clouds to derive forest structure, which help to explain how fire spreads through vegetation. As the vast majority of fires is started by humans, my final product will incorporate anthropogenic behavoir as predictors.
