Abstract

Most surface water bodies are deteriorating, resulting in health risks and environmental damage. This study aimed to assess the performance of the modeled agri-environmental transition scenarios for restoring freshwater quality within the protection perimeter of strategic surface water drinking water catchments. Realistic agri-environmental scenarios with combined agronomic orientations were tested using a well-calibrated ecohydrological model. Their performance was quantified based on pesticide concentration reductions in freshwater bodies, focusing on temporal and spatial variability, using non-parametric tests. Our results show that it is possible to differentiate cropping mitigation scenarios according to their ability to limit pesticide transfers, taking into account the most influential biogeochemical factors in the catchment, their agronomic orientation, and their progressive implementation. Our study is also applicable to other contexts.

评估减少地表饮用水源中农药浓度的农业环境战略，法国西南部夏朗德河流域沿海地区

大多数地表水体正在恶化，导致健康风险和环境破坏。本研究旨在评估模拟农业环境过渡方案的性能，以恢复战略性地表水饮用水集水区保护范围内的淡水质量。研究利用一个经过良好校准的生态水文模型，对具有综合农艺导向的现实农业环境方案进行了测试。使用非参数检验法，根据淡水水体中农药浓度的降低情况，对这些方案的性能进行了量化，重点关注时间和空间的可变性。我们的研究结果表明，考虑到集水区最有影响的生物地球化学因素、农艺学取向以及逐步实施的情况，可以根据限制农药转移的能力来区分不同的种植减缓方案。我们的研究也适用于其他情况。

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
