TAAP as a Model for Shared Aquifer Agreements
Through the Transboundary Aquifer Assessment Program (TAAP), collaborators study shared aquifers along the US-Mexico border. Recent UArizona graduate Dr. Elia M. Tapia-Villaseñor and WRRC Director Dr. Sharon B. Megdal recently published “The U.S.-Mexico Transboundary Aquifer Assessment Program as a Model for Transborder Groundwater Collaboration” in a Special Issue of the journal Water. In this work, the authors analyzed the TAAP Cooperative Framework as a model for scientific assessment by exploring 17 elements of collaboration within the Framework and examining six other transboundary aquifer agreements. Their results show that successes within the TAAP Cooperative Framework for assessment are consistent with existing aquifer agreements, suggesting the TAAP approach may serve as a model for others pursuing transboundary aquifer assessments worldwide. This paper appears in the Special Issue Advances in Transboundary Aquifer Assessment, for which Megdal and Dr. Anne-Marie Matherne from USGS are guest editors. They invite researchers focusing on aquifers, groundwater availability and quality, and water use to submit their manuscripts by April 1, 2021.

Dr. Megdal joins Honors College Big Ideas, Grand Challenges Sustainability Event

The WRRC is pleased to feature the following article, prepared by UArizona Honors College Assistant Dean for Student Engagement, Karna Walter.

On Wednesday, February 17, the UArizona Honors College sponsored the last of four events that were part of the Big Ideas, Grand Challenges Series. This event, which focused on sustainability, featured a multifaceted panel of experts who think about sustainability from different points of view. Dr. Sharon B. Megdal from WRRC was one of the panelists, alongside Dr. Solomon Dobrowski (Professor and Landscape Ecologist in the Department of Forest Management, University of Montana), John Goldstein (Head of the Sustainable Finance Group at Goldman Sachs), and Dr. Joaquin Ruiz (Vice President of Global Environmental Future, UArizona). Lorraine Rivera (Host and Producer of Arizona 360 for Arizona Public Media) facilitated the dialogue as panelists considered questions on what climate change might look like in the future in Arizona and elsewhere; how students can play a role in advocating for sustainability; ways to productively engage with colleagues across borders to tackle challenges related to sustainability; what can be done at individual and systemic levels; and whether business growth and sustainability can coexist. Dr. Megdal was a welcome addition to this dialogue, bringing her expertise in water management, both locally and globally. The audience of Honors students, staff and faculty, and friends of the Honors College enjoyed a lively and, in the end, hopeful discussion of what we can do to better understand the challenges we face and to mitigate them in the future.

WRRC RAPIDS Navigating Watershed Planning in a Virtual World 
As we approach the one-year anniversary of working virtually, the WRRC Water RAPIDS team leans into collaborative watershed planning and research with our partners in the Cobre Valley from afar. In November 2020, the team co-convened the Third Annual Cobre Valley Water Forum alongside the Cobre Valley Watershed Partnership (CVWP) and Gila County Cooperative Extension. The forum’s virtual format enabled broad participation, bringing together over 60 community members to consider how healthy forests and uplands support the overall health of the watershed. Participant feedback throughout the two-day forum was integrated into a recently released forum summary.

Volunteers Build Capacity

According to APW Director Kerry Schwartz, "Volunteers are the driving force to the success of our program." Over the years, thousands of community members have volunteered at community water festival events. With this added capacity, APW has spread the fourth grade standards-based Arizona Water Festival (AWF) program to 26 communities across the state. This school year, the COVID-19 pandemic has APW exploring new ways to engage volunteers. For example, AWF Celebrations of Learning are 50-minute, live streaming events that not only engage students in learning the “magic” of the earth’s water cycle, but offer added value. Volunteers and sponsors now offer their own videos on STEM careers, the water delivery system, wastewater treatment, or water management for healthy rivers. Students have the opportunity to ask volunteers questions about the video content. Some volunteers are behind the scenes creating the videos and some assist us in managing technology during the events. The bottom line is that volunteers give their time because they care and their efforts are helping to enrich the experience for these students.

Summary of Ecosystem Services of Riparian Restoration: A Review of Rock Detention Structures in the Madrean Archipelago Ecoregion

The WRRC is pleased to feature the following article summary prepared by the author, US Geological Survey research scientist (and UArizona Affiliate), Dr. Laura M. Norman.
The US Geological Survey (USGS) Aridlands Water Harvesting Study has been investigating the potential to sculpt landscapes in the Madrean Archipelago Ecoregion and quantifying impacts (on hydrology, vegetation, and sediment) over the past 10 years. This article first introduces the long history of rock detention structures (RDS) locally, as agricultural tools, and then summarizes results of a multi-year research project conducted on RDS being used for restoration. The study area is the Madrean Archipelago Ecoregion, along the US-Mexico border, a biodiversity hotspot of the planet. Ecosystem services of RDS are described with examples from analyses. I argue that global water availability may be one facet of the environment not yet being properly accounted for economically and propose using tradeoffs among ecosystem services to safeguard ephemeral riparian areas (i.e. to offset footprints of groundwater pumping downstream through the investment of RDS installations or to compensate practitioners if RDS can be used to offset greenhouse gas emissions).

Survey Reveals Arizonans' Concern for Environmental and Water Issues
A Survey conducted by the Nina Mason Pulliam Charitable Trust and the Morrison Institute for Public Policy at ASU showed that Arizona voters rank the environment in their top three public policy priorities. The survey polled a representative sample of 800 registered voters in 2017 and 2020. According to the poll, water pollution ranks as Arizonans’ top environmental concern (91% of voters indicated they are concerned or very concerned), followed by the air quality in cities and large towns (89%), protection of wildlife (86%), and vehicle emission (84%). Seventy-one percent of Arizonans' believe the state is currently in a drought, 54% believe Arizona’s drought is the result of climate change, and 64% believe the state will suffer a water shortage at some point in the next 50 years. Between 2017 and 2020, the opinion that the environment should be Arizona’s top priority increased among most categories of voters. In fact, 64% of respondents felt that “protecting the environment should be given priority, even at the risk of slowing economic growth.” When assuming water for home use to be the number one priority, Arizonans' listed agriculture second and water for the environment third.
