Humans and Hydrology at High Latitudes: Water Use Information, Version 1.0

This data set contains water use information for Canadian and Alaskan communities as well as general water-use estimates provided by the United States Geological Survey (USGS) for the whole of the United States. These data are utilized in the Arctic Rapid Integrated Monitoring System (ArcticRIMS) project to improve the development of the water stress model. This water stress model shows the effects of water resources, humans and climate change in the Arctic. Recent studies suggest that climate change will have a significant impact on arctic hydrology. However, it is currently unknown which regions of the pan-Arctic are most vulnerable to future changes. In order to begin to address the future change to freshwater availability on a pan-arctic scale, a system of arctic typologies were used to enable the integration of biophysical data with socio-cultural data produced regionally, such as demographics and water values. Those mature data sets were used to study the strategic transformations of the high latitude water cycle. The overall objective of this research is to use a wide array of existing data sets in a synthesis effort to describe the vital role of freshwater in the lives of people in the pan-Arctic, how it has changed in the recent past, and how it is likely to change in the future.

本数据集涵盖加拿大与阿拉斯加社区的用水信息，以及美国地质调查局（United States Geological Survey, USGS）针对全美范围发布的通用用水估算数据。上述数据已应用于北极快速综合监测系统（Arctic Rapid Integrated Monitoring System, ArcticRIMS）项目，用于优化水资源压力模型的开发。该水资源压力模型可揭示北极地区水资源、人类活动与气候变化间的相互作用效应。近期研究显示，气候变化将对北极水文系统产生显著影响，但目前学界尚未明确泛北极地区哪些区域最易受到未来变化的冲击。为探究泛北极尺度下淡水供给的未来变化趋势，研究团队采用北极类型学体系，实现了区域产出的生物物理数据与社会文化数据（如人口统计数据、水资源价值数据）的融合集成。上述成熟数据集被用于研究高纬度水循环的关键转型过程。本研究的总体目标为：通过整合多套现有数据集开展综合分析，系统阐明淡水在泛北极地区民众生活中的核心作用，梳理其近期变化轨迹，并预测其未来演化趋势。
