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4千万人依靠分配过多的科罗拉多河供水。气候变化、干旱、城市发展和人口增长加剧了水资源短缺的严重程度。净零城市用水（NZUW）城市通过当地可用和可持续的供水满足特定社区的需求，而不会损害互连系统和长期供水。该研究协调网络的目标是向美国西南部的NZUW城市移动。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后调查，将在七个已确定的研究空白中制定NZUW框架。美国西南部不同规模和位置的城市将被用作该框架开发的试验台（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）。所有感兴趣的各方将通过网站、通讯和社交媒体积极促进参与。研究协调网络的长期影响预计包括：(1)一个新的NZUW概念框架来协调多学科研究；(2)通过综合模型提供决策支持，定量评估NZUW系统在空间和时间尺度上的动态权衡；(3)在学术、公共和私营部门之间建立新的伙伴关系；(4)为4000万人提供有弹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、人与水联系在一起，水的“语言”是一种由人类决策塑造的技术系统。这些系统是20世纪对降水机制、发展模式、工程科学和城市行政组织的理解的产物。目前的城市水系统方法和用于建设、管理和调节这些系统的机构已不足以解决水系统面临的不确定性，需要整合新的社会环境知识。该研究协调网络将支持向城市零水净（NZUW）城市迈进，以实现有弹性和可持续的水未来。遵循净零能源和碳系统的概念模型，该项目将定义和检查在科罗拉多河服务的不同规模和位置的干旱和半干旱城市场景（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）中追求NZUW方法的可行性和价值。NZUW是一个基于地点的、全面的、定量的框架，用于指导弹性和可持续水系统的发展，该系统可以应对急性冲击和慢性压力，并将动态社会环境系统整合到分析中。NZUW是一个框架，通过考虑到向有弹性、可持续的水未来过渡所必需的综合社会环境系统，推动了当前城市水系统的概念界限。研究协调网络的第一个目标是创建一个整体的研究路线图，以解决城市向可持续、有弹性的城市水系统转变的挑战。研究缺口将跨越七个研究领域：(1)替代水源和改造，(2)分布式软基础设施，(3)地表水和地下水相互作用，(4)处理和管理技术，(5)公众偏好，(6)政策和治理，以及(7)城市水的公平和正义。第二个目标是通过时事通讯、网站和社交媒体发起、协调和传播纽泽西大学相关研究。第三个目标是跨多个时间尺度的评估。最终的研究路线图报告将全面详细说明七个已建立的研究领域的研究差距以及NZUW框架的情景测试结果。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
