This second webinar in the “Get Ready” series will focus on committees under the Governor’s Water Augmentation, Innovation, and Conservation Council. Philip Richards, Chair of the Desalination Committee, will discuss why desalination is being used as a possible solution for Arizona’s current water challenges and how it can help meet future water needs. In addition, committee Chair Wade Noble and Co-Chair Timothy Thomure will provide updates from the Long-Term Water Augmentation and Post-2025 AMAs Committees.
Agrivoltaics: co-locating agriculture and photovoltaics to increase food and energy production while decreasing water use
Greg Barron-Gafford, Associate Professor and Associate Director for the School of Geography & Development
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. We have been studying the novel solution of co-locating agriculture and photovoltaics – agrivoltaics – as an untapped opportunity to simultaneously increase food and energy production while reducing water use.
Greg Barron-Gafford began his faculty career as an ecologist, graduating from the EEB program here at UA. Being broadly trained in plant and ecosystem science, his worldview grew as he managed experiments in and around Biosphere 2 and across the Southwest. Upon joining the faculty of the School of Geography & Development, his passions for physical science, environmental and social justice, and using research to solve real-world problems finally truly merged.

Changes in aquifer storage derived from microgravity and water level monitoring in the Tucson Active Management Area
Over the past 20 years, the Tucson Active Management Area has experienced fluctuations in aquifer storage. These changes are a result of recharging imported water and changing groundwater pumping regimes. The USGS uses microgravity to directly measure storage changes in space and time, while Tucson Water measures depth to water in its measurable production wells in an annual round-up. By examining the data from both agencies, it is possible to characterize changes in the regional aquifer and monitor interesting trends in specific geographic areas.
