Soil erosion by water and loss of soil organic carbon (SOC) are two major contributors to global land degradation. However, the impact of soil erosion and its effect on SOC in the fragile, sensitive alpine ecosystem of the Tibetan Plateau, where climate change is amplified, is not well understood. We used the Universal Soil Loss Equation (USLE) ensemble model to analyse soil erosion, SOC loss, and
