项目摘要

The anticipated impacts of climate-change induced glacier shrinkage on the water security of mountains and downstream lowlands is a major global concern. However, the connections between climate change, glacier shrinkage, water security and local adaptive capacity are multi-dimensional and non-linear. In many regions of the world including Peru, the physical and human processes that govern them are poorly understood. Therefore, understanding these process, their impacts and implementing adequate science-based adaptation strategies requires an interdisciplinary approach. This approach should combine advancing the state-of-the-art of glaciological and hydrological process understanding, with new insights in current and future levels of water security, human vulnerability, and adaptive capacity.We propose to address this challenge by developing an integrated glacier - water security assessment model to transform our understanding of the impact of glacier shrinkage on water security and to inform policy practices in Peru. We identify the lack of glaciological, hydro-climatological, and water resources data as a major bottleneck to achieve this. Therefore, we propose participatory water resources monitoring as a radically new approach to transform our knowledge of physical processes, constraining water resources models, and supporting evidence-based policy-making. We have assembled a world-leading consortium that combines high-level expertise in field monitoring and computer simulation of glaciers and water resources in Peru, with pioneers of participatory data collection for sustainable development and policy-support. This consortium is ideally placed to generate a breakthrough in data availability on the link between glacier reduction and current and future water security. This is needed to build the next generation of glaciological and hydrological models that can support the design and implementation of adequate climate adaptation strategies.We will use the Vilcanota-Urubamba Basin in southern Peru as our case study. This basin hosts the largest tropical ice cap (Quelccaya) and it is characterised by a very complex water management context and high data scarcity. Our project will follow a "source to tap" paradigm, in which we will deliver the first fully integrated water resources vulnerability assessment framework for glacier-fed basins, comprising state-of-the-art glaciology, hydrology, water demand characterisation, and water security assessment. We will design targeted glacio-hydrological and water resources monitoring campaigns, to complemented existing monitoring efforts of our project partners and collaborators, and new remotely sensed data sets. This campaign will be implemented using the principles and tools of participatory monitoring and knowledge co-creation that our team has pioneered in the tropical Andes.The datasets produced by this approach, combined with existing monitoring implemented by our team and collaborators, will allow us to build an integrated water supply-demand-vulnerability assessment model for glacierized basins, and to use this to evaluate adaptation strategies at the local scale.For the latter, we have engaged with a set of policy stakeholders in Peru that play a key role in the implementation of recent transformative legislation on Peruvian water resources management, and in particular in the new law on the implementation of water funds to invest in catchment interventions (Law 30215).Working directly with these stakeholders will ensure that our approach focuses on locally relevant adaptation strategies, including novel approaches such as the use of nature-based solutions and the restoration of ancestral water "seeding and harvesting practices", thus providing both the scientific basis and the operational tools that support the implementation of this legal framework.

气候变化引起的冰川收缩对山区和下游低地的水安全的预期影响是全球的主要问题。但是，气候变化，冰川收缩，水安全和局部适应能力之间的联系是多维和非线性的。在包括秘鲁在内的世界许多地区，对其的身体和人类过程的理解很少。因此，了解这些过程，它们的影响和实施适当的基于科学的适应策略需要跨学科的方法。这种方法应该结合冰川和水文过程的最新理解，以及对当前和未来水平水平，人类脆弱性和适应能力的新见解。我们建议通过开发综合冰川 - 水安全评估模型来解决这一挑战，以改变我们对冰川对水安全和培养政策实践的影响的理解。我们认为缺乏冰川，水资源和水资源数据是实现这一目标的主要瓶颈。因此，我们建议参与式水资源监测作为一种彻底的新方法，以改变我们对物理过程，限制水资源模型并支持基于证据的决策的知识。我们组建了一个世界领先的财团，该联盟结合了秘鲁冰川和水资源的现场监测和计算机模拟方面的高级专业知识，以及参与性数据收集的先驱，以进行可持续发展和政策支持。理想情况下，该财团是在冰川减少与当前和未来水安全之间的链接上产生数据可用性的突破。这是建立下一代冰川和水文模型的必要条件，这些模型可以支持适当的气候适应策略的设计和实施。我们将使用秘鲁南部的Vilcanota-urubamba盆地作为我们的案例研究。该盆地拥有最大的热带冰盖（Quelccaya），其特征是非常复杂的水管理环境和高数据稀缺。我们的项目将遵循“点击”范式的“来源”，在该范式中，我们将为冰川喂养的盆地提供第一个完全整合的水资源脆弱性评估框架，其中包括最先进的冰川学，水文学，水需求特征和水安全评估。我们将设计有针对性的冰川水和水资源监测活动，以补充我们项目合作伙伴和合作者的现有监视工作，以及新的远程感知的数据集。这项运动将使用我们的团队在热带安第斯山脉中开创的参与式监控和知识共同创造的原理和工具进行实施。已经与秘鲁的一系列政策利益相关者互动，这些利益在实施秘鲁水资源管理的最新变革性立法中起着关键作用“播种和收获实践”，因此提供了支持该法律框架实施的科学基础和操作工具。
