  1. 16. Where there is road, there is fire (influence): An exploratory study on the influence of roads in the spatial patterns of Swedish wildfires of 2018

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gabriel Romeo Ferriols Pavico; [2023]
    Keywords : Geography; GIS; Wildfire; Fire Spatial Patterns; Road; Conformity; FWI; Earth and Environmental Sciences;

    Abstract : This study focuses on the Swedish wildfire season of 2018, when the country incurred ten times more than the average burnt area that occurred in previous years. The study aims to address a broad research question: Do roads influence the size of the burned area? This study fills the gap in research on the effects of roads in the spatial patterns of wildfires.
