Arroyo 2026 - Spanish University of Arizona. Water Resources Research Center.; Marsh, Katherine N.; Eden, Susanna El agua une comunidades, ecosistemas y economías sin importar las fronteras políticas. Esto es evidente en América del Norte, donde Estados Unidos, México, Canadá y las Naciones Indígenas comparten ríos, acuíferos y costas. Estos recursos hídricos compartidos sostienen a las comunidades y la industria, pero compartirlos trae desafíos. A medida que se intensifican las presiones del crecimiento demográfico, el clima y el desarrollo económico, la colaboración transfronteriza seguirá siendo la base para gestionar los recursos hídricos fronterizos. La edición de Arroyo de este año explora el tema del agua y las fronteras, basándose en los debates de la Conferencia Anual del WRRC de 2025, Fronteras compartidas, aguas compartidas. Esta publicación destaca la historia de la cooperación en materia de agua en Arizona, Estados Unidos, México, Canadá y las Naciones Indígenas, al tiempo que analiza las iniciativas actuales para ampliar, conservar y proteger los recursos hídricos compartidos mediante alianzas entre los sectores público y privado. El objetivo de esta edición de Arroyo es ofrecer a los lectores una visión clara de cómo la colaboración transfronteriza está configurando la gestión del agua en la actualidad y de cómo las alianzas pueden garantizar un acceso equitativo a un agua limpia y segura.

Arroyo 2026 University of Arizona. Water Resources Research Center.; Marsh, Katherine N.; Eden, Susanna Water links communities, ecosystems, and economies irrespective of political borders. This is evident in North America, where the United States, Mexico, Canada, and Indigenous nations share rivers, aquifers, and coastlines. These shared water resources sustain communities and industry, but sharing brings challenges. As pressures from population growth, climate, and economic development intensify, cross-border collaboration will continue to form the foundation for managing border water resources. This year’s Arroyo explores the topic of water and borders, building on discussions from the 2025 WRRC Annual Conference, Shared Borders, Shared Waters. The publication highlights the history of water cooperation involving Arizona, the United States, Mexico, Canada, and Indigenous Nations while examining current efforts to expand, conserve, and protect shared water resources through public and private partnerships. This Arroyo aims to provide readers with a clear understanding of how cross-border collaboration is shaping water management today and how partnerships can ensure equitable access to clean, reliable water.

Arroyo 2025 University of Arizona. Water Resources Research Center.; Bauer, Austin; Eden, Susanna Arizona relies on a diverse portfolio of water resources to meet its overall water needs, including groundwater, Colorado River water, in-state rivers, and reclaimed water. While all that water may meet our needs today, there is uncertainty about the future.

Arroyo 2024 University of Arizona. Water Resources Research Center.; Lee, Courtney; Bauer, Austin; Eden, Susanna Water resources in Arizona are under stress from climate change, a two-decade megadrought, and chronic overuse. These combined influences have led to surface water losses, drying streams and wetlands, and groundwater depletion as pumping exceeds replenishment. Communities are facing the possibility that the water sources they rely on now may shrink in the future, or even vanish. Uncertainty regarding Colorado River water — a large component of Arizona’s water portfolio and one that is shared with six other US basin states — also raises questions about Arizona’s water future. The quality of available water is a concern as well. Where supply is limited, lower quality water and wastewater can be valuable resources, but only if they can be treated to suitable standards. These concerns beg the question: What can be done? That very question was the focus of the Water Resources Research Center's 2023 annual conference, “What Can We Do? Solutions to Arizona’s Water Challenges.” Panelists and presenters highlighted ongoing efforts to address the state’s water challenges, as well as new and innovative solutions currently under development. During the conference, several additional themes emerged, such as the need for better, more accessible data, improved technology, and collaboration. Drawing from the 2023 annual conference, this Arroyo explores themes of water supply and quality, conservation, technological innovation, data, collaboration, funding, and workforce development. It provides an overview of the challenges facing Arizona’s water supplies and specific solutions discussed during the conference, including ongoing, new, and emerging ideas, applications, and examples.
