- Socio-technical scales in socio-environmental modeling: Managing a system-of-systems modeling approachIwanaga, Takuya; Wang, Hsiao-Hsuan; Hamilton, Serena H.; Grimm, Volker; Koralewski, Tomasz E.; Salado, Alejandro; Elsawah, Sondoss; Razavi, Saman; Yang, Jing; Glynn, Pierre; Badham, Jennifer; Voinov, Alexey; Chen, Min; Grant, William E.; Peterson, Tarla Rai; Frank, Karin; Shenk, Gary; Barton, C. Michael; Jakeman, Anthony J.; Little, John C. (2021-01)System-of-systems approaches for integrated assessments have become prevalent in recent years. Such approaches integrate a variety of models from different disciplines and modeling paradigms to represent a socioenvironmental (or social-ecological) system aiming to holistically inform policy and decision-making processes. Central to the system-of-systems approaches is the representation of systems in a multi-tier framework with nested scales. Current modeling paradigms, however, have disciplinary-specific lineage, leading to inconsistencies in the conceptualization and integration of socio-environmental systems. In this paper, a multidisciplinary team of researchers, from engineering, natural and social sciences, have come together to detail socio-technical practices and challenges that arise in the consideration of scale throughout the socioenvironmental modeling process. We identify key paths forward, focused on explicit consideration of scale and uncertainty, strengthening interdisciplinary communication, and improvement of the documentation process. We call for a grand vision (and commensurate funding) for holistic system-of-systems research that engages researchers, stakeholders, and policy makers in a multi-tiered process for the co-creation of knowledge and solutions to major socio-environmental problems.
- Water-Use Data in the United States: Challenges and Future DirectionsMarston, Landon T.; Abdallah, Adel M.; Bagstad, Kenneth J.; Dickson, Kerim; Glynn, Pierre; Larsen, Sara G.; Melton, Forrest S.; Onda, Kyle; Painter, Jaime A.; Prairie, James; Ruddell, Benjamin L.; Rushforth, Richard R.; Senay, Gabriel B.; Shaffer, Kimberly (Wiley, 2022-05-10)In the United States, greater attention has been given to developing water supplies and quantifying available waters than determining who uses water, how much they withdraw and consume, and how and where water use occurs. As water supplies are stressed due to an increasingly variable climate, changing land-use, and growing water needs, greater consideration of the demand side of the water balance equation is essential. Data about the spatial and temporal aspects of water use for different purposes are now critical to long-term water supply planning and resource management. We detail the current state of water-use data, the major stakeholders involved in their collection and applications, and the challenges in obtaining high-quality nationally consistent data applicable to a range of scales and purposes. Opportunities to improve access, use, and sharing of water-use data are outlined. We cast a vision for a world-class national water-use data product that is accessible, timely, and spatially detailed. Our vision will leverage the strengths of existing local, state, and federal agencies to facilitate rapid and informed decision-making, modeling, and science for water resources. To inform future decision-making regarding water supplies and uses, we must coordinate efforts to substantially improve our capacity to collect, model, and disseminate water-use data.
