Since the impacts of climate change will be felt most directly through changes in water availability and water security, adequate tools are required to support water resources management decisions for the medium and long term. The Climate Risk Informed Decision Analysis (CRIDA) provides a pathway for more localized vulnerability assessments of water resources under climate change, while encompassing the uncertainty of current global climate projections. Within this framework, this paper demonstrates a climate stress test to identify changes in key performance indicators defined through local stakeholder consultations using a bottom-up approach. When applied to a case study in the Limari River basin in Chile, the stress test highlights the vulnerability of the reservoir system to climate variability and change, through a comprehensive analysis of 43 Global Circulation Models, of which 34 were retained. The Level of Concern (LoC) was defined as high, due to a high plausibility for entering into adverse water security conditions, that are expected to provoke a significant impact in the highly productive areas of the watershed. As demonstrated by the case study, the climate stress test provides a relevant assessment tool for potential climate change impacts on critical components of the water system in vulnerable catchments.

由于将通过水供应和水安全的变化最直接地感受到气候变化的影响，因此需要足够的工具来支持中长期的水资源管理决策。气候风险信息决策分析（CRIDA）为气候变化下水资源的更局限性评估提供了一种途径，同时涵盖了当前全球气候预测的不确定性。在此框架内，本文演示了一种气候压力测试，以使用自下而上的方法来确定通过与当地利益相关方的磋商确定的关键绩效指标的变化。当应用于智利利马里河流域的案例研究时，压力测试突出了水库系统对气候变化和变化的脆弱性，通过对43种全球流通模型的综合分析，保留了34种。由于进入不利的水安全状况的可能性很高，因此人们将“关注程度”（LoC）定义为“高”，这预计会在该流域高产地区产生重大影响。如案例研究所示，气候压力测试为潜在的气候变化对脆弱流域水系统关键组成部分的潜在影响提供了一种相关的评估工具。
