Transboundary Groundwater Resilience Network Hosts First Annual Workshop

Transboundary Groundwater Resilience Network Hosts First Annual Workshop

By Jeanette Torres, NM WRRI Program Coordinator, & Christine Tang, NM WRRI Research Scientist, Assc.

The Transboundary Groundwater Resilience (TGR) Network of Networks (formerly known as TGRR) funded by the National Science Foundation’s Accelerating Research through International Network-to-Network Collaborations (AccelNet) program, was pleased to host its first annual workshop on September 28 and 29. TGR is a collaboration between the New Mexico Water Resources Research Institute (NM WRRI), West Big Data Innovation Hub, and the San Diego Supercomputer Center (SDSC). This partnership was created to develop a new, international network of networks to connect water, social, data, and systems science to establish an innovative transboundary groundwater approach. This effort strives to provide leadership, volunteer, and engagement opportunities for all its partners, especially students and early-career researchers.

This interactive event garnered over thirty participants throughout the workshop. On the first day of the workshop, Dr. Sam Fernald, Director of the New Mexico Water Resources Research Institute and Principal Investigator (PI) on the project, gave opening remarks regarding the current outlook of TGR, including a name change to reflect the progression of the project. TGR aims to evolve from creating connections and content for research networks to engaging with stakeholders and providing actionable guidelines for transboundary groundwater resilience.

After these opening remarks, the workshop began with an introduction to Systems Thinking and Systems Mapping by researchers from the System Dynamics Group at the University of Bergen, Norway. They provided an overview of how to draw systems maps using causal loop diagramming (CLD). CLDs depict, for example, how an increase in variable A causes an increase in variable B, all else equal, then how an increase in variable B causes an increase (or decrease) in variable A, thus reinforcing (or balancing) behavior in systems. Each participant was assigned to an interactive breakout session led by a facilitator who guided a hands-on approach to CLD. In these rooms, attendees were asked to identify critical issues related to groundwater depletion and graphically represent key variables’ (e.g., groundwater level, water demand, etc.) behavior over time using an online whiteboard to collaborate with other session members. These responses were then clustered according to common themes to develop a systems map that enables participants to understand and specify the feedback relationships between concepts. Facilitators frequently engaged participants by inquiring about possible connections that are part of the causal loops.

The workshop continued on Thursday, where participants were gathered once more into breakout groups to discuss the results of the previous day’s online whiteboard session. Facilitators summarized previously identified loops and emphasized the synergistic or competing loops. Systems mapping can be an intricate activity as seen in Figure 1 above. From this exercise, one can see that this group identified both balancing (indicated by a red arrow with a negative sign inside of it) and reinforcing (indicated by a black arrow with a positive sign) feedback loops. In this group’s map, an increase in Water Demand increases Water usage, which decreases Groundwater, which decreases Total Fresh water, which decreases Freshwater availability, which decreases Industrial Activities, which decreases Water Demand. When going around a single feedback loop to determine loop polarity (+ reinforcing or – balancing), one starts by increasing a variable and only considering the variables in that loop. Think about that loop in isolation. Keep all variables outside of that loop constant. After one finishes going around the loop and finds that the same variable has decreased, then one has identified a balancing feedback loop.

After the systems mapping activity, there was a research agenda-setting activity where participants could contribute their thoughts and ideas concerning significant connections, areas that seemed especially challenging, and variables that could be influential in a system. Once these relationships were established, attendees could “plot” these onto a matrix by importance and uncertainty to prioritize research needs. Once this activity concluded, each breakout group returned to the main room and presented their findings. The systems maps from this workshop will be publicly available for researchers and policymakers to understand this participant group’s mental model of how to achieve transboundary groundwater resilience. In addition to the workshop, NM WRRI and the University of Bergen administered a pre- and post-workshop survey to understand what participants’ transboundary groundwater resilience research priority areas are and whether that is reflected in the systems maps. The University of Bergen plans to analyze the data to produce a journal publication in collaboration with the TGR team.

This interactive workshop is just one of several opportunities to provide input on the challenges and needs for more effective transboundary groundwater research and management. Interested individuals, institutions, and networks can list themselves on the TGR Network of Networks Member Directory by filling out the new TGR Member Suave Survey.  This form collects detailed and personalized data from each survey-taker to grow and evolve the directory to create more possible collaboration opportunities. TGR is actively seeking volunteers to engage and learn about coordinating international, cross-disciplinary research collaboration that will lead to actionable agendas for resilience. Volunteers will learn how to organize, run, and sustain a collaborative setting while learning about each other’s work to develop a shared understanding of the scientific language used by different groups. TGR specifically encourages participation from underrepresented groups in academia, and the team will work with the volunteers to ensure that their position aligns with their career goals. Interested individuals can apply here.

A video recording of opening remarks and presentation links are available on the TGR website.

NM WRRI Awards UNM Graduate Student a Student Water Research Grant for his Work Transforming Wastewater Sewage into Recoverable Energy

NM WRRI Awards UNM Graduate Student a Student Water Research Grant for his Work Transforming Wastewater Sewage into Recoverable Energy

By Marcus Gay, NM WRRI Sr. Student Program Coordinator

Carl L. Abadam, a graduate student at the University of New Mexico’s Department of Civil, Construction, and Environmental Engineering, is working on research transforming wastewater sewage into renewable energy. Abadam believes that wastewater sludges are primed for energy recovery due to their high lipids content and consistent availability. The process Abadam is working on is called hydrothermal liquefaction (HTL) and is a wet thermochemical process that exploits the untapped energy content of wastewater sludges and transforms them into valuable products like sustainable biocrude oil. According to Abadam, “it’s an extreme pressure cooker that takes excreta and fuels your car.” He explains that HTL is a transformative technology that could shift our perspective from viewing waste as a problem to seeing waste as a sustainable energy source. The New Mexico Water Resources Research Institute has awarded Abadam a Student Water Research Grant for his important research on this topic.

Under the guidance of his faculty advisor Dr. Anjali Mulchandani, Abadam’s study will focus on biocrude yields in relation to the overall wastewater treatment train. According to Abadam, “while anaerobic digestion seems to be the technology of choice for sludge stabilization, the greater efficiency, contaminant removal, and higher product valorization of HTL can potentially change how the solids process train looks like in future wastewater facilities.” Abadam believes that as regulations prioritize the effluent quality of wastewater, higher contaminant concentrations in the solids effluent could make current biosolids management (i.e., landfilling, incineration, and land application) less viable. Therefore, Abadam believes wastewater sludge stabilization technology must keep pace with the technologies in the liquids train to ensure the future sustainability of treated wastewater.

Abadam will present this research at the upcoming 67th Annual New Mexico Water Conference in Las Cruces, New Mexico, and plans to attend the Water Environment Federation Residuals and Biosolids Conference in 2023. Abadam is planning on graduating with a Master of Science in Civil Engineering with a focus on Environmental Engineering in May of 2023. After graduation, Abadam plans to pursue a PhD in environmental engineering and continue his work researching innovative technologies for water and wastewater.

Meet the Researcher, Blair Stringam, Professor, New Mexico State University

Meet the Researcher, Blair Stringam, Professor, New Mexico State University

By Jeanette Torres, NM WRRI Program Coordinator

Blair Stringam is a professor for the Plant and Environmental Sciences Department at New Mexico State University (NMSU) and has been an affiliate since 2008. He currently advises undergraduate students and serves on several graduate student committees. Stringam enjoys teaching students how to find fulfillment in their research and inspiring them to discover better ways to manage water resources. He has a long history with the New Mexico Water Resources Research Institute (NM WRRI) and has been awarded funding through the Faculty Water Research Grant Program. Stringam’s funded research topics include furthering the development of a model that describes the influence of the river and canal systems on aquifers and advancing software to operate remote water control sites to provide timely water deliveries. He has published two technical completion reports with NM WRRI (report no. 372 and report no. 393).

Stringam’s areas of expertise center around irrigation, water measurement and management, sensor design/applications, control systems, precision agriculture, and open channel flow modeling. He is currently working on two types of technologies that will help secure water supplies for an extended amount of time. The first project is a user-friendly, inexpensive, and highly-accurate sensor that will allow water users to better monitor soil moisture to maintain that only the required amount of water is used for crops. This sensor is composed of lasers, a micro-processing unit, and a radio transmitter, which allows for easy installation and will be linkable to the user’s cellphone. While this research is still in process, this cellphone connection will enable the sensor to provide updates to the farmer so they can closely monitor crop water use and apply irrigation water as needed.

The second project Stringam is working on is developing a feedback control automation system that will be used to operate irrigation canal systems. This will give canal managers more precision over water deliveries to their users and consistently monitor canal changes to conserve water. This technology will involve using sensors and control computers installed with the required management software. With this system, irrigation districts will be able to promptly provide more precise amounts of water to users. These two projects fully support what Stringam believes to be one of the most challenging issues concerning his research: the extended drought situation in the Southwestern U.S. Stringam believes the increasing demand for water and its continued misuse are areas of significant importance.

Stringam earned his BS in Agricultural Engineering from the University of Alberta in Edmonton. His MS and PhD degrees were earned in Agricultural and Irrigation Engineering, and Biological and Agricultural Engineering, respectively, from Utah State University in Logan. He has 28 Extension and referred publications, has contributed to 12 proceedings, and holds two patents for a Continuous Flow Measurement Recorder and Recording Method, and an Automated Farm Turnout System. “I have always enjoyed conducting research. . . Throughout my education, I enjoyed classes where I was able to use the scientific method to discover and develop a deeper understanding of water management and control issues,” Stringam states.

Stringam’s long-term research goal is to continue discovering and enhancing practical methods and technologies that provide water users with straightforward water conservation strategies. He plans to pursue water conservation research that will benefit the State of New Mexico by ensuring that water-scarce communities have access to a consistent water supply, and looks forward to any future research collaborations with NM WRRI.
