Abstract Dry detention reservoirs are frequently used as a measure to alleviate flood risk. When implemented on agricultural land, they decrease the productive capacity of a rural landscape and negatively impact soil characteristics, crop quality and quantity, agricultural infrastructure (i.e., irrigation equipment), and agro-economics. The Slovenian government prepared a Detailed Plan of National Importance to ensure flood safety in the Lower Savinja Valley. The proposed plan foresees the implementation of a chain of 10 dry reservoirs (520 ha of agricultural land) to provide a higher level of flood protection for the cities of Celje and Lasko. We explored how economic calculation can adequately address flood risk management initiatives and prevent adverse effects on high-quality agricultural land. The results of agro-economic scenarios for the study area showed that expected damage to agriculture production (crop yield) in a worst-case flood event occurring during the growing period would be EUR 1.7 million. The most exposed farms would suffer damage in the range of three to five average annual salaries. These agro-economic findings indicate the need for discussion on agriculture-focused mitigation measures before the construction of flood protection measures.

农业生产和防洪干滞蓄水库：以斯洛文尼亚下萨维尼亚河谷为例

摘要 干蓄水库经常被用作减轻洪水风险的措施。在农业土地上实施时，它们会降低农村景观的生产能力，并对土壤特性、作物质量和数量、农业基础设施（即灌溉设备）和农业经济产生负面影响。斯洛文尼亚政府制定了一份具有国家重要性的详细计划，以确保下萨维尼亚河谷的洪水安全。拟议的计划预计将实施 10 个干水库（520 公顷农业用地）链，为采列和拉斯科市提供更高水平的防洪。我们探讨了经济计算如何充分解决洪水风险管理举措并防止对优质农田的不利影响。研究区域的农业经济情景结果表明，在生长期发生的最坏情况洪水事件中，对农业生产（作物产量）的预期损失为 170 万欧元。受灾最严重的农场将遭受平均年薪三到五个不等的损失。这些农业经济研究结果表明，在构建防洪措施之前需要讨论以农业为重点的缓解措施。
