A Call to Cities: Run Out of Water or Create Resilience and Abundance?

New management choices, with new approaches to urbanization and integrated water- energy-food management, are emerging as critical to combat water stress. Urban strategies and tactics are explored in this chapter with a focus on scaling effective solutions and approaches. This includes a focus on small, modular, and integrated water-energy-food hubs; off-grid and localized “circular economy” services that are affordable, accessible, and reliable; blended finance for new technologies, infrastructure and business models, strategic plans, and policies; and urban, behavioral, and decision sciences-informed deci - sions and new public-private-research-driven partnerships and processes. There are two key messages: first, business as usual could lead to “running out” of water where it’s needed most—in cities and for agricultural and industrial production. Second, “innova tors” and “early adopters” of market-based and data-driven efforts can help scale solu - tions led by people and communities investing in new ways to integrate urban water, energy, and food systems. The chapter concludes with discussion on a new, proactive “maturity” model, enabling integrated urban infrastructure systems, governance, and cross-sector innovation. This includes market-based and data-driven responses that first focus on improving quality of life, sustainability, and resilience of communities, bringing valued services via water-energy-food nexus decisions.
