Introduction to the special issue on fire impacts on hydrological processes
Fire has been present on the Earth since vegetation began colonizing the continents (Santos et al., 2017). The role of fire on terrestrial sedimentation processes was already highlighted by Schumm (1968) in his pioneering research to understand the detachment, transport, and sedimentation of material on the Planet. The use of fire by humans as a tool that transformed the landscapes of the world has been widely accepted (Wang et al., 1999). Glacial-interglacial changes can affect vegetation with resulting implications for global fire regimes and trace gas emissions (Thonicke et al., 2005). Wildfire effects on vegetation can, in turn, alter soil erosion rates (Lenton, 2001), which is mainly due to the control plants exert on soil erosion processes (López-Vicente et al., 2021).
