Food, energy, and water systems, especially in drylands, are vulnerable to projected changes in climate – primarily changes in the timing and amount of precipitation and rising air temperatures. For the most part, we grow non-dryland adapted food within a dryland climate through a reliance on irrigation, and the water resource requirements are large and increasing. At the same time, renewable energy in drylands is vulnerable to the same warming trends that threaten food systems. The abundance of sunlight in the southwest US constitutes a significant solar energy resource.
WRRC Brown Bag - Innovating the Urban Water System: The Architecture of a Decentralized Future
Courtney Crosson, Assistant Professor, UA School of Architecture
Globally, cities are facing increased water stress under growing populations, degrading infrastructure, and changing climate patterns. This imbalance between available water resources and projected urban water demands presents tremendous challenges for water resource management, necessitating novel planning and design strategies and tools. Rainwater harvesting (RWH) has been pointed to as one partial answer; however, the capacity of such a solution to address urban water deficits had been largely untested. This talk will investigate two components of decentralized water infrastructure’s ability to meet urban water stress: network capacity and regulatory restriction. First, the talk will discuss recent research that evaluates the capacity of Tucson, AZ to become water independent using rainwater. Remote sensing, localized daily rainfall, and municipal water meter data were used to construct a dynamic model of the city’s potential passive and active RWH network. Second, the talk discusses the regulatory hurdles to make such infrastructure a reality at a commercial scale.

Her current research advances decentralized water systems to address pressing problems facing cities – whether water scarcity in the US Southwest or safe and affordable water access in informal settlements in Nairobi, Kenya.
