Despite the relevant literature on the advantages of no-till (NT) management, the world area under NT is only 10% of the arable land, probably due to several limiting factors as climate, soil types, farming systems and yield. Soil conservation practices and particularly NT soil management are able to provide many ecosystem services (ESs). This paper suggests a framework to determine the area distribution of soil erosion control and food security ESs trade-offs furnished by NT, starting from the potential soil erosion and aridity index maps. The interaction between the potential soil erosion and the aridity index showed that different trade-offs and synergies of multiple ESs may occur and need to be interpreted. The yield success probability of NT with respect to CT (P(NT)) and soil erosion tolerance (SET) were considered to determine four classes of the NT adaptability index, which represent the NT ability to support multiple ESs, under the environmental condition. For 2020 as a baseline, and 2050 as a future scenario, in between latitudes 35° and 47°, an analysis was carried out, focusing on the arable lands of five European Mediterranean countries (France, Greece, Italy, Portugal and Spain), which are potentially cropped with durum wheat. Results showed that, for the considered arable land area, under NT soil management and from a food security point of view, the potential durum wheat area, under climate change pressure, slightly increases, if residues are retained. On the contrary, if residues are removed, the potential durum wheat area is very limited for both the baseline and the 2050 scenario. The area distribution corresponding to the NT adaptability index classes could be suitable for stakeholders to modulate payments for agri-environmental measures, based on the actual provided ESs.

干旱指数,水土流失和气候驱动地中海耕地免耕生态系统服务的权衡

尽管有关于免耕(NT)管理优势的文献报道,但NT下的世界面积仅占耕地的10%,这可能是由于气候,土壤类型,耕作系统和产量等诸多限制因素所致。土壤保护实践,尤其是NT土壤管理能够提供许多生态系统服务(ES)。本文提出了一个框架,从潜在的土壤侵蚀和干旱指数图开始,确定由NT提供的土壤侵蚀控制和粮食安全ES权衡取舍的区域分布。潜在的土壤侵蚀与干旱指数之间的相互作用表明,不同的折衷和多重协同效应ES可能会发生,需要进行解释。考虑到NT相对于CT的产量成功概率(PNT))和土壤侵蚀耐受性(SET),以确定NT适应性指数的四类,它们代表了NT支持多个ES的能力。,在环境条件下。以2020年为基准,以2050年为未来情景,在35°至47°纬度之间进行了分析,重点是五个欧洲地中海国家(法国,希腊,意大利,葡萄牙和西班牙)的耕地,可能使用硬质小麦种植。结果表明,在考虑耕地面积,在NT土壤管理和从来看,潜在的硬粒小麦区域粮食安全角度看,气候变化的压力,稍微增加下,如果残留物被保留。相反,如果去除残留物,则基线和2050年情景中硬质小麦的潜在面积都非常有限。NT对应的区域分布适应性指数类别可能适合利益相关者根据实际提供的ES来调整农业环境措施的付款。
