Healthy soil is the foundation underpinning global agriculture and food security. Soil erosion is currently the most serious threat to soil health, leading to yield decline, ecosystem degradation and economic impacts. Here, we provide high-resolution (ca. 100 × 100 m) global estimates of soil displacement by water erosion obtained using the Revised-Universal-Soil-Loss-Equation-based Global Soil Erosion Modelling (GloSEM) platform under present (2019) and future (2070) climate scenarios (i.e. Shared Socioeconomic Pathway [SSP]1-Representative Concentration Pathway [RCP]2.6, SSP2-RCP4.5 and SSP5-RCP8.5). GloSEM is the first global modelling platform to take into account regional farming systems, the mitigation effects of conservation agriculture (CA), and climate change projections. We provide a set of data, maps and descriptive statistics to support researchers and decision-makers in exploring the extent and geography of soil erosion, identifying probable hotspots, and exploring (with stakeholders) appropriate actions for mitigating impacts. In this regard, we have also provided an Excel spreadsheet that can provide useful insights into the potential mitigating effects of present and future alternative CA scenarios at the country level.
健康的土壤是全球农业和粮食安全的基础。土壤侵蚀是目前对土壤健康最严重的威胁，导致产量下降、生态系统退化和经济影响。在这里，我们利用基于修正的通用土壤流失方程的全球土壤侵蚀建模（GloSEM）平台，提供了当前（2019 年）和未来（2070 年）气候情景下（即共享社会经济路径 [SSP]1-代表性浓度路径 [RCP]2.6、SSP2-RCP4.5 和 SSP5-RCP8.5）水蚀引起的土壤位移的高分辨率（约 100×100m）全球估算。GloSEM 是第一个考虑区域耕作系统、保护性农业（CA）的缓解效应以及气候变化预测的全球建模平台。我们提供了一组数据、地图和描述性统计信息，以支持研究人员和决策者探索土壤侵蚀的范围和地理分布，确定可能的热点，并探索（与利益相关者一起）采取适当的缓解措施来减轻影响。在这方面，我们还提供了一个 Excel 电子表格，可以深入了解当前和未来替代 CA 情景在国家层面的潜在缓解效果。
