土壤侵蚀是对土壤功能的严重威胁，导致土地生产力下降和多种场外效应。在这里，我们使用多模型方法展示了由水、风、耕作和收获引起的土壤侵蚀的空间风险，以及这些不同过程共同发生的地方。此外，我们分析了这些多重侵蚀共生的地点可能与预测的干湿气候条件的增加相交的地方。在欧盟1.1亿公顷（M ha）的可耕地中，我们的估计表明，4300万公顷易受单一侵蚀因素影响，1560万公顷易受两个侵蚀因素影响，0.81万公顷易受三个或更多侵蚀因素影响。大约320万公顷的可耕地容易受到洪水、干旱、水蚀和风蚀增加的可能相互作用的影响。我们认为，这组预测可作为制定有效分层监测网络和根据2023-2027年共同农业政策制定有针对性缓解战略的基础。《欧盟绿色协议》所倡导的可持续、碳中和和生物多样性友好型农业系统的道路，是通过一项主题战略来保护土壤免受多种同时发生的侵蚀过程的影响。
Soil erosion is a serious threat to soil functions leading to land productivity decline and multiple off-site effects. Here we show, using a multi-model approach, the spatial risk of soil erosion by water, wind, tillage and harvesting and where the co-occurrence of these different processes is observed. Moreover, we analysed where these locations of multiple erosion co-occurrence are likely to intersect with the projected increase of dry/wet climate conditions. Of the similar to 110 million hectares (M ha) of arable land in the European Union, our estimates show that 43 M ha are vulnerable to a single driver of erosion, 15.6 M ha to two drivers and 0.81 M ha to three or more drivers. About 3.2 M ha of arable land are vulnerable to the possible interaction of increased flood, drought, water and wind erosion. We contend that this set of predictions serves as a basis for developing an efficient stratified monitoring network and informing targeted mitigation strategies under the Common Agricultural Policy 2023-2027. The road to the sustainable, carbon-neutral and biodiversity-friendly system of agriculture advocated for in the EU Green Deal goes through a thematic strategy for soil protection from multiple concurrent erosion processes.
