Global post-fire soil erosion

Wildfires induce significant disturbances to topsoil properties, increasing surface runoff and accelerating soil erosion. Despite extensive research, a global, spatially explicit quantification of cumulative post-fire erosion has been missing. This dataset addresses that gap by providing annual global estimates of post-fire soil erosion from 2001–2019. Soil loss is quantified using the Revised Universal Soil Loss Equation (RUSLE), where post-fire modifications to cover-management (C) factors parameterized to account for burn severity and land cover characteristics after fire. The dataset integrates erosion estimates with spatial information enabling the assessment of cumulative soil degradation driven by repeated burns. This resource supports global-scale analysis of wildfire-induced land degradation and offers a basis for post-fire risk mitigation and policy strategies aligned with Land Degradation Neutrality targets.
