The American West: Aridification as a driver for innovation

Scarcity drives innovation.

An example of how scarcity drives innovation is the impact of aridification in the American West, which is accelerating innovation in technology, public policy, and partnerships. Declining surface and groundwater supplies are fostering the adoption of water efficiency, reuse, and alternative water sources. Public policy is also slowly evolving to confront the new normal of water availability by adopting water-efficiency and reuse directives.

First, why does scarcity drive innovation?

A Harvard Business Review article by Sohrab Vossoughi from March 2012 makes a case that provides insights into what we are seeing in the American West. The Silver Lining to Scarcity: It Drives Innovation argues that resource abundance (real and perceived) often “dulls” innovation, while scarcity drives better ideas and technologies.

In summary, when conditions are good, enterprises (in both the private and public sectors) tend to keep doing what has worked, rather than questioning whether their approach is truly optimal. Scarcity shatters this thinking. Tight budgets, shrinking markets, or external shocks force leaders to confront trade‑offs and focus on what actually matters.

Water scarcity falls into the category of “external shocks.”

The author emphasizes that constraint‑driven innovation is about disciplined prioritization and challenging the status quo. Rather than waiting for conditions to improve, enterprises facing resource constraints can use this as an opportunity to develop strategies that thrive within new supply constraints. The overall message is that scarcity, intelligently managed, can be a powerful catalyst for innovation and renewal. Organizations that respond by clarifying strategy, simplifying structures, and focusing experimentation are more likely to emerge stronger if constraints ease.

A recent example of how aridification of the American West has fostered innovation in partnerships is captured in the article; Arizona wants to buy desalinated water from California, (ETAR News, June 16, 2026). This is an interesting development and, in my opinion, very likely part of the path forward for the American West.

Arizona agencies are moving toward a first-of-its-kind deal to “buy” desalinated ocean water from California via a Colorado River water swap, as reported by KTAR/ETAR and summarized by several regional outlets. The initiative reflects Arizona’s search for new supplies as the Colorado River declines and post‑2026 operating rules are renegotiated.

The core idea is not to physically transport Pacific Ocean water into Arizona, but to fund or help expand desalination capacity in Southern California so that California users can rely more on desalinated water and, in turn, reduce their draws from the Colorado River. Arizona would then take a portion of the conserved Colorado River water under an exchange arrangement, effectively turning seawater into an additional Colorado River allocation without a physical pipeline from the coast to the desert.

The focal facility is the Claude “Bud” Lewis Carlsbad Desalination Plant in San Diego County, which currently produces about 56,000 acre‑feet of potable water annually and could potentially be expanded by about 6,000 acre‑feet. Because San Diego’s overall water portfolio is now relatively robust, the San Diego County Water Authority has some flexibility to reduce its Colorado River withdrawals if more desalinated water is brought online, creating room for Arizona (and possibly Nevada) to access additional Colorado River water.

According to state and federal officials, Arizona’s Water Infrastructure Finance Authority (WIFA) and partner agencies have been authorized to negotiate with California utilities and private companies on such desalination‑linked exchanges. This builds on earlier WIFA work evaluating seven major augmentation proposals, including both California and Mexico desalination concepts as well as wastewater reuse and upstream storage projects, most of which depend on swap mechanisms rather than direct conveyance. The Bureau of Reclamation has also signed an agreement to explore lower‑basin water trades involving desalinated or recycled water, giving the concept federal backing.

Supporters of this innovative strategy argue that the arrangement could provide a new tool for managing shortages across the Southwest, diversify Arizona’s supply portfolio, and demonstrate how coastal desalination can indirectly bolster inland water security. Critics and skeptics point to the high cost and energy footprint of desalination, potential impacts on marine ecosystems and brine disposal in California, and the complexity of negotiating long‑term interstate water swaps at a time when all Colorado River states face cutbacks. Negotiators hope to have a more formal framework in place by the end of the current water year, but detailed terms—volumes, pricing, cost‑sharing for plant expansion, and the durability of Colorado River credits—are still to be worked out.

This is an innovative approach to managing declining surface water in the Colorado River Basin. Innovative partnerships and the adoption of innovative technologies, funding, and financing is the path forward. Assuming that the Colorado River will return to “normal” is not the path forward.

Onward.
