Drought affects the European Alpine mountain region, despite a humid climate. Droughts' damaging character in the past and increasing probability in future projections call for an understanding of drought impacts in the mountain regions. The European Drought Impact report Inventory (EDII) collects text reports on negative drought impacts. This study presents a considerably updated EDII focusing on the Alpine region. This first version release of an Alpine Drought Impact report Inventory (EDII_ALPS) classifies impact reports into categories covering various affected sectors and enables comparisons of the drought impact characteristics. We analysed the distribution of reported impacts on the spatial, temporal and seasonal scale and by drought type for soil moisture drought and hydrological drought. For the spatial analysis, we compared the impact data located in the Alpine region to the whole of Europe. Furthermore, we compared impact data between different climatic and altitudinal domains (the northern region vs. the southern region and the pre-Alpine region vs. the high-altitude region) and between the Alpine countries. Compared to the whole of Europe, in the Alpine region agriculture and livestock farming impacts are even more frequently reported, especially in the southern region. Public water supply is the second most relevant sector but overall less prominent compared to Europe, especially in spring when snowmelt mitigates water shortages. Impacts occur mostly in summer and early autumn, with a delay between those impacts initiated by soil moisture and those initiated by hydrological drought. The high-altitude region shows this delay the strongest. From 1975 to 2020, the number of archived reports increases, with substantially more impacts noted during the drought events of 1976, 2003, 2015 and 2018. Moreover, reported impacts diversify from agricultural dominance to multi-faceted impact types covering forestry, water quality, industry and so forth. Though EDII_ALPS is biased by reporting behaviour, the region-specific results of negative drought impacts across the water-rich European mountain region demonstrate the need to move from emergency response to prevention and preparedness actions. These may be guided by EDII_ALPS' insights to regional patterns, seasons and drought types.

一份阿尔卑斯干旱影响清单，以探索山区过去的干旱

尽管气候潮湿，但干旱仍影响着欧洲高山山区。过去干旱的破坏性特征以及未来预测中日益增加的可能性要求了解干旱对山区的影响。欧洲干旱影响报告清单 (EDII) 收集有关干旱负面影响的文本报告。这项研究提出了一个相当更新的 EDII，重点是高山地区。阿尔卑斯干旱影响报告清单 (EDII _{ALPS) 的}第一个版本) 将影响报告分类为涵盖各个受影响部门的类别，并能够比较干旱影响特征。我们分析了报告的对土壤水分干旱和水文干旱的空间、时间和季节尺度以及干旱类型的影响分布。对于空间分析，我们将位于阿尔卑斯地区的影响数据与整个欧洲的影响数据进行了比较。此外，我们比较了不同气候和海拔区域（北部地区与南部地区以及前阿尔卑斯地区与高海拔地区）之间以及高山国家之间的影响数据。与整个欧洲相比，在阿尔卑斯地区，农业和畜牧业的影响报告更为频繁，尤其是在南部地区。公共供水是第二个最相关的部门，但与欧洲相比，总体而言不那么突出，尤其是在融雪缓解水资源短缺的春季。影响主要发生在夏季和初秋，土壤水分引起的影响和水文干旱引起的影响之间存在延迟。高海拔地区显示出这种延迟最强。从 1975 年到 2020 年，存档报告的数量增加，在 1976 年、2003 年、2015 年和 2018 年干旱事件期间注意到的影响要大得多。此外，报告的影响从农业主导地位到多方面的影响类型多样化，包括林业、水质、工业等等。虽然 EDI 土壤水分引起的影响与水文干旱引起的影响之间存在延迟。高海拔地区显示出这种延迟最强。从 1975 年到 2020 年，存档报告的数量增加，在 1976 年、2003 年、2015 年和 2018 年干旱事件期间注意到的影响要大得多。此外，报告的影响从农业主导地位到多方面的影响类型多样化，包括林业、水质、工业等等。虽然 EDI 土壤水分引起的影响与水文干旱引起的影响之间存在延迟。高海拔地区显示出这种延迟最强。从 1975 年到 2020 年，存档报告的数量增加，在 1976 年、2003 年、2015 年和 2018 年干旱事件期间注意到的影响要大得多。此外，报告的影响从农业主导地位到多方面的影响类型多样化，包括林业、水质、工业等等。虽然 EDI 报告的影响多种多样，从农业主导地位到多方面的影响类型，包括林业、水质、工业等。虽然 EDI 报告的影响多种多样，从农业主导地位到多方面的影响类型，包括林业、水质、工业等。虽然 EDI_ALPS报告行为存在偏见，整个欧洲山区水资源丰富的干旱负面影响的特定区域结果表明，需要从应急响应转向预防和准备行动。这些可能以 EDII _ALPS对区域模式、季节和干旱类型的见解为指导。
