Climate change and accelerating glacier recession is affecting the water cycle and the future of water resources in the Peruvian Andes. In the Cordillera Blanca, the most glacierized mountain range in the tropics, the natural and social systems of the region are very dependent on glacial water resources and it is considered to be one of the most vulnerable to glacier-related water stress in the world. This interdisciplinary and collaborative research project will evaluate the new system of freshwater governance that is emerging in the Andes and how glacial dynamics are transforming melt water rates as they rapidly recede. The research will generate new insights into the coupled natural and human consequences of glacial recession in the tropical highlands by examining the combined effects of glacier recession on downstream watersheds, the resilience of livelihood systems and the ways in which economic change and shifting water governance are factors in this hydrologic, ecological, and social transformation. The research will also generate new hydrologic models and derive quantitative estimates of glacial water dynamics. As glacier recession is accelerating in the Cordillera Blanca, dramatic changes in the Andean hydrologic regime pose significant challenges to Andean society. Data and observations from the project will inform water resource policy makers, global change specialists, development practitioners and scientists who study co-related topics such as chemical weathering and physical sedimentation. In examining of climate-glacier-water-society dynamics in the Cordillera Blanca, this research will provide critical information to urban residents, industries, farmers, and policymakers that will inform adaptive strategies and responses to global climate change. Integral to the project is a cross-cultural education and outreach plan that will increase awareness, inform policy managers, strengthen institutional partnerships, and educate the next generation of interdisciplinary scientists at both the undergraduate and graduate level.

气候变化和冰川加速衰退正在影响秘鲁安第斯山脉的水循环和水资源的未来。 在热带地区冰川最严重的布兰卡山脉，该地区的自然和社会系统非常依赖冰川水资源，被认为是世界上最容易受到冰川相关水资源压力的地区之一。 这个跨学科的合作研究项目将评估安第斯山脉正在出现的新淡水治理系统，以及冰川动力学如何在快速消退时改变融水率。 该研究将通过研究冰川退缩对下游流域的综合影响、生计系统的恢复力以及经济变化和水治理转变的影响因素，对热带高地冰川退缩造成的自然和人类后果产生新的见解。在水文、生态和社会转型中。该研究还将生成新的水文模型并得出冰川水动力学的定量估计。随着布兰卡山脉冰川退缩加速，安第斯水文状况的巨大变化给安第斯社会带来了重大挑战。 该项目的数据和观察结果将为水资源政策制定者、全球变化专家、发展实践者和研究化学风化和物理沉积等相关主题的科学家提供信息。 在研究布兰卡山脉的气候-冰川-水-社会动态时，这项研究将为城市居民、工业、农民和政策制定者提供重要信息，为全球气候变化的适应性战略和应对措施提供信息。 该项目的一个组成部分是跨文化教育和推广计划，该计划将提高认识，为政策管理者提供信息，加强机构伙伴关系，并在本科生和研究生层面教育下一代跨学科科学家。
