项目摘要

Over 40 million people rely on an overallocated Colorado River for their water supply. Climate change, drought, urban development, and population growth are increasing severity of water shortages. Net Zero Urban Water (NZUW) cities meet the needs of a given community with a locally available and sustainable water supply, without detriment to interconnected systems and long-term water supply. The goal of this research coordination network is to move toward NZUW cities in the US Southwest. Through a series of workshops, literature reviews, stakeholder interviews, focus group discussions, and pre and post workshop surveys, an NZUW framework will be developed across seven identified research gaps. Cities of varying size and location in the US Southwest will be used as testbeds for the development of this framework (e.g., Los Angeles, Las Vegas, Denver, Albuquerque, Tucson, Colorado Springs). Participation by all interested parties will be actively promoted through a website, newsletter, and social media. The long term impacts of the research coordination network are expected to include: (1) a novel NZUW conceptual framework to coordinate multidisciplinary research; (2) the delivery of decision support through comprehensive models to quantitatively evaluate dynamic trade-offs in NZUW systems across spatial and time scales; (3) development of new partnerships between academic, public, and private sectors; and (4) a resilient and sustainable urban water supply for the 40 million people serviced by the Colorado River. Urban water systems are inherently complex socio-environmental systems, connecting water to humans and humans to water, whose ‘language’ is a technical system shaped by human decisions. These systems are products of a 20th century understanding of precipitation regimes, development patterns, engineering science, and city administrative organizations. The current urban water system approach and the institutions used to build, manage, and regulate these systems are no longer adequate to address the uncertainties facing water systems, and there is a need to integrate new socio-environmental knowledge. This research coordination network will support a move toward Net Zero Urban Water (NZUW) cities for a resilient and sustainable water future. Following the conceptual models of net zero energy and carbon systems, this project will define and examine the viability and value of pursuing a NZUW approach in arid and semi-arid urban scenarios of varying size and location serviced by the Colorado River (e.g., Los Angeles, Las Vegas, Denver, Albuquerque, Tucson, Colorado Springs). NZUW is a place-based, comprehensive, quantitative framework to guide the development of resilient and sustainable water systems that can respond to acute shocks and chronic stressors and integrate dynamic socio-environmental systems into the analysis. NZUW is a framework that pushes the current conceptual boundaries of urban water systems by accounting for the integrated socio-environmental systems necessary to transition to a resilient, sustainable water future. The first objective of the research coordination network is the creation of an overall research road map to address the challenges of shifting cities toward sustainable, resilient urban water systems. Research gaps will be identified across seven research areas: (1) alternative water sources and retrofit, (2) distributed soft infrastructure, (3) surface and groundwater interactions, (4) treatment and management technologies, (5) public preference, (6) policy and governance, and (7) equity and justice across urban water. The second objective is the initiation, coordination, and dissemination of NZUW related research through a newsletter, website, and social media. The third objective is assessment across multiple time scales. The final research road map report will comprehensively detail the research gaps across the seven established research areas and the results of the scenario testing of the NZUW framework.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

超过4000万人依靠一条整体分配的科罗拉多河来供水。气候变化，干旱，城市发展和人口增长越来越严重。净零城市水（NZUW）城市满足特定社区的需求，并具有本地可用且可持续的供水，而不会损害相互联系的系统和长期供水。该研究协调网络的目标是朝着美国西南部的Nzuw城市迈进。通过一系列研讨会，文献综述，利益相关者访谈，焦点小组讨论以及研讨会前和研讨会调查，将在七个确定的研究差距中开发NZUW框架。美国西南地区各种规模和位置的城市将被用作该框架开发的测试床（例如，洛杉矶，拉斯维加斯，丹佛，阿尔伯克基，图森，科罗拉多斯普林斯）。所有有关方面的参与将通过网站，新闻通讯和社交媒体积极促进。研究协调网络的长期影响预计包括：（1）一个新型的NZUW概念框架，以协调多学科研究；（2）通过综合模型提供决策支持，以定量评估跨空间和时间尺度的NZUW系统中的动态权衡；（3）在学术，公共和私营部门之间建立新的伙伴关系；（4）科罗拉多河服务的4000万人的韧性和可持续的城市供水。城市供水系统本质上是复杂的社会环境系统，将水与人类和人类连接起来，其“语言”是人类决策所塑造的技术系统。这些系统是20世纪对降水制度，发展模式，工程科学和城市行政组织的了解的产品。当前的城市供水系统方法以及用于建立，管理和规范这些系统的机构不再足以解决水系统面临的不确定性，并且有必要整合新的社会环境知识。该研究协调网络将支持向净零城市水（NZUW）城市迈出的转变，以实现富裕和可持续的水的未来。遵循净零能量和碳系统的概念模型，该项目将定义和研究在各种大小和位置在Colorado River（例如Los Angelles，Los Angelles，Las Vegas，Las Vegas，Las Vegas，Denver，Denver，Albuquerque，Tucson，Tucson，Colorado Sproings）服务的干旱和半干旱城市场景中采用NZUW方法的可行性和价值。 NZUW是一个基于地方的，全面的定量框架，可指导弹性和可持续水系统的开发，可以响应急性冲击和慢性压力源，以及综合的动态社会环境系统。 Nzuw是一个框架，通过考虑过渡到过渡到弹性，可持续的水的未来所需的综合社会环境系统，从而突破了城市供水系统的当前概念界限。研究协调网络的第一个目标是创建整体研究路线图，以应对将城市转向可持续的弹性城市水系统的挑战。研究差距将在七个研究领域中确定：（1）替代水源和改造，（2）分布式软基础设施，（3）地表和地下水相互作用，（4）治疗和管理技术，（5）公共偏爱，（6）政策和治理，以及（7）在城市水中的公平和公平和正义。第二个目标是通过新闻通讯，网站和社交媒体对NZUW相关研究的主动性，协调和传播。第三个目标是跨多个时间尺度进行评估。最终的研究路线图报告将全面详细介绍NZUW框架的七个既定研究领域的研究差距以及情景测试的结果。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准的评估来评估。
