   From Watersheds to Washington: How Science Can Shape Smarter Phosphorus Policy

   What can watershed science teach us about designing more effective phosphorus policy? In this episode of the PhosForUs Policy Series, host Barira Rashid sits down with her PhD advisor, Dr. Rebecca Muenich, whose research connects watershed modeling, nutrient management, water quality, animal agriculture, and phosphorus sustainability. They discuss what policymakers may overlook when phosphorus is managed one farm, permit, or practice at a time; how legacy phosphorus complicates expectations for water-quality improvement; and why better monitoring is essential for informed decision-making. The conversation also explores Barira’s research using remote sensing and artificial intelligence to identify and monitor animal feeding operations. What began as a geospatial research problem has developed into broader questions about manure phosphorus, environmental data gaps, watershed impacts, agricultural sustainability, and policy. Together, Barira and Becca consider how improved AFO information could support phosphorus management, whether policy has kept pace with phosphorus recovery and circularity, and what researchers can contribute to decisions beyond academia.

   Phosphorus, Policy, and the Systems That Shape Outcomes

   What does phosphorus policy actually look like beyond regulations and legislation, and how do institutions shape the outcomes we see on the ground? In this episode of PhosForUS, hosts Alison Deviney (Postdoctoral Researcher, STEPS Center) and Barira Rashid (PhD Candidate, University of Arkansas) sit down with Jay Rickabaugh, Assistant Professor of Public Administration at North Carolina State University, to explore the governance side of phosphorus sustainability. Together, they discuss how phosphorus is managed across different agencies, sectors, and scales, the challenges of coordinating agricultural, environmental, and water quality goals, and what the recent designation of phosphorus as a critical mineral could mean for future policy discussions. They also examine how institutions, incentives, and decision-making structures influence phosphorus outcomes, and where opportunities exist for more integrated and systems-oriented approaches. Whether you work in environmental policy, agriculture, sustainability, or resource management, this conversation provides a foundation for understanding one of the central questions facing phosphorus sustainability today: how can governance systems better support long-term environmental, economic, and societal outcomes? Topics discussed: phosphorus policy, environmental governance, public administration, critical minerals, water quality, nutrient management, sustainability policy, systems thinking, and phosphorus sustainability.

   The Policy Landscape of Phosphorus: Where Agriculture, Conservation, and Water Quality Collide

   What does phosphorus policy actually look like on the ground, and who gets to shape it? In this season premiere of PhosForUs, hosts Barira Rashid (PhD Candidate, University of Arkansas) and Hector Fajardo (PhD Candidate, NC State University) sit down with Jonathan Coppess, Associate Professor of Agricultural Policy at the University of Illinois Urbana-Champaign, to unpack how phosphorus shows up in U.S. farm policy, from conservation programs and nutrient management plans to the economic pressures farmers face every day. Together, they explore the tension between phosphorus as a critical food security resource and a water quality threat, ask whose voices shape agricultural phosphorus policy, and look ahead at what questions still need deeper attention, including nutrient recovery, circular nutrient use, and better coordination between agriculture and environmental goals. Whether you work in agriculture, environmental science, water policy, or just want to understand how nutrient management decisions get made, this episode sets the foundation for a season built around one big question: how do we govern phosphorus better?

   Exploring the Aquatic Triple Bottom Line Scenario in South FL: Science, Community, and Phosphorus Sustainability with Dr. Jehangir Bhadha

   The Everglades Agricultural Area in South Florida is the home of the most unique and fertile soils in the country—organic-rich Histosols with over 80% organic matter. These soils, once part of a vast wetland ecosystem, have been drained over the past century to support agriculture, especially sugarcane, rice, and vegetables. But beneath this productivity lies a hidden concern: decades of phosphorus fertilizer use have created a massive reserve of legacy phosphorus. Hosted by Xue Bai and Anik Mahmud. Music by Lucas Crane.

   P, People, and… Pets? Phosphorus Dynamics in the Urban Triple Bottom Line Scenario Site in Phoenix, AZ

   Phosphorus dynamics within any system can be complex, but none are more complex than urban systems. The STEPS Center has established one of its key Triple Bottom Line (TBL) scenario sites as the Central Arizona–Phoenix Long Term Ecological Research (CAP-LTER) site, which considers the unique dynamics between the urban metropolis of Phoenix and its peri-urban, rural, and environmental surroundings. In this episode of PhosForUs, we chat about phosphorus dynamics in urban settings, including recovering phosphorus from urban waste streams, modeling of phosphorus flows within urban scenarios, and identifying future trends in engineering, technology, and regulation that can drive phosphorus dynamics. Hosted by Lucas Crane, Maheen Mahmood, and Minhazul Islam Link to Metson et al., 2012 paper discussed in the episode: https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/11-0865.1 (https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/11-0865.1) Link to Deviney et al., 2024 paper on TBL sites: https://www.mdpi.com/2071-1050/16/23/10429 (https://www.mdpi.com/2071-1050/16/23/10429) Link to previous PhosForUs podcast episode on urine diversion: https://open.spotify.com/episode/3nP8IOo0r7MCFidYco5WjC?si=CwDSAL0zQceUS2jnGZs5SA (https://open.spotify.com/episode/3nP8IOo0r7MCFidYco5WjC?si=CwDSAL0zQceUS2jnGZs5SA)

   Exploring Triple Bottom Line Scenario Sites: Pathways to Convergence Research

   The STEPS Center uses tools called boundary objects to help build convergence capacity – that is, the ability to effectively co-create new knowledge – across its multidisciplinary research community. This episode is an introduction to one of those boundary objects, the Triple Bottom Line Scenario Site, also known as TBL Sites. TBL Sites are geographic locations that, for STEPS at least, encompass a phosphorus flow in a particular ecological setting. These sites provide researchers with access to resources, data, and stakeholder networks, as well as specific contexts related to phosphorus management. In this episode we will introduce you to the concept of the TBL Site and how the STEPS Center is using these boundary objects to learn about phosphorus challenges, and to test new ideas and innovations. Future episodes will take a deeper look at the current TBL Sites. Hosted by Smitom Borah and Alison Deviney Featuring (in order of appearance) Maude Cuchiara, Natalie Nelson, Paul Westerhoff, Jacob Jones, and Jay Rickabaugh.

    A P(ee) Research Update: Urine Diversion for P Sustainability

    What if I told you that your urine can be a potential solution for the world’s phosphorus conundrum? In this episode, we discuss how urine can be a resource instead of a waste and chat about two upcoming peer-reviewed articles based on STEPS research. Lucas explains why urine diversion systems are more feasible in airports than in restaurants, and Ashton talks about why we should be looking to state, not federal, regulation as the most likely pathway for regulatory change in the US. We also share our own personal journeys into P (and pee) research. Urine for a good time! The two main articles that were discussed: Benchmarks for urine volume generation and phosphorus mass recovery in commercial and institutional buildings (https://www.sciencedirect.com/science/article/pii/S2589914724000173) Researchers must address regulatory regimes to scale up adoption of urine diversion systems in the U.S. (in review at the time of recording, link will be added once published) And if you want to learn more about using the power of the sun for urine treatment, check out this article on Solar distillation of human urine to recover non-potable water and metal phosphate mineral (https://iwaponline.com/wst/article/88/2/486/96169/Solar-distillation-of-human-urine-to-recover-non).

    What and Why: Convergence Research

    Modern challenges of today create the need for more efficient and effective research to tackle them. By what means are we achieving this? Convergence research is how. It’s been elevated as one of the National Science Foundations 10 Big Ideas, and it is the foundation that the STEPS Center has been built upon. In this episode, we want to elaborate on the fine details of convergence research. We’ll investigate the technical definition, the reason it’s so important, and what it looks like in practice. As we do so, we’ll hear from several members of the STEPS community, researchers and scholars alike! By the end, we hope to provide a good understanding of what convergence research is, and why we appreciate it so much. Hosted by Alison Deviney and George Hotelling Featuring Jacob Jones, Jan Genzer, Shwetha Delanthamajalu, Jessica Deaver, Lucas Crane, Kim Bourne, Jay Rickabaugh, and Christine Hendren.
