Resilient Governance for Urban Water Systems in the Anthropocene

In an era marked by significant socio-environmental shifts, the Resilient Governance for Urban Water Systems in the Anthropocene project focuses on heavily engineered resource systems, such as urban water systems, facing both gradual changes and sudden extreme events. It explores the challenges of allocating resources and attention between crisis response and long-term planning. Decision-makers often lean towards reactive strategies, potentially increasing vulnerability to future failures. This research seeks to establish a new resource governance paradigm, encompassing redesigning “soft” social and informational infrastructure alongside traditional built infrastructure. By integrative cognitive, collective action, and robust control theories, the project aims to enhance the resilience of Urban Water Coupled Infrastructure Systems (UW-CISs) in the face of dynamic climate change impacts.

This research delves into the complex interactions within urban water systems, examining how individuals, groups, and networks respond to environmental changes, focusing on predictive capabilities aiming to reduce surprises by aligning actions with anticipated future conditions. Through this approach, the project aims to understand better risk perception, collective action dynamics, and robustness-fragility tradeoffs within UW-CISs. By incorporating hydroclimatic data, physical infrastructure, and institutional design, the research offers scenario planning and predictive modeling for future water reliability and affordability, addressing the immediate need for decision support in navigating the challenges of the Anthropocene.

Urban water supply systems in the United States are designed to be robust to a wide range of historical hydrological conditions in both their physical infrastructure and in the institutional arrangements that govern their use. However, these systems vary greatly in their capacity to respond to new and evolving stressors on water supplies, such as those associated with climate change. Developing a more precise understanding of the complexity of interactions between the environmental and human components of urban water systems, specifically via their institutions, has the potential to help identify institutional design choices that can foster proactive transitions to more sustainable operating states. This article adapts the Institutional Grammar (IG) within the Robustness of Coupled Infrastructure Systems Framework to assess how a heavily engineered system's institutional configuration may impact its ability to transition to more sustainable management practices. While use of the IG has historically been limited in larger-N studies, our application demonstrates its flexibility in revealing variation in specific components across cases. The analysis finds the structure of formal institutions shape the interactions between actors differently, and that institutional diversity exists across environmental contexts. The extent to which this institutional diversity drives transitions remains an open question. The results highlight both the importance of and challenges involved with developing longitudinal data on social and natural system interactions.

Understanding the complex impacts of human settlement patterns on social and natural systems is critical for immediate and long-term policy decisions and ecosystem preservation. Land-use patterns can be conceptualized as a form of integrated natural-human system within urban regions. However, extant scholarship on urban development and sprawl often overlooks the institutional diversity which exists across countries and regions. Development and land-use are politically charged governance issues, and these studies have rarely examined the influences of local political institutions on land-use changes across countries and over time. To help build cumulative knowledge on such urban systems, this study examines landscape change in Poland, which has undergone significant institutional evolution since the fall of the Soviet Union. Drawing from the urban and social-ecological systems (SES) literatures, we estimate spatio-temporal models of the interactive effects of socio-economic and political variables on land-use intensity. Consistent with an SES approach, the analysis finds that characteristics of the institutional design of land-use regulation – local autonomy, the productivity of the resource, and the predictability of land-use dynamics – influence more-intensive landscape changes over the study period (2006–2018). Specifically, both the electoral stability of the mayor and wealth of the community have a positive interactive effect on the conversion of landscapes to more urban uses. Development is also influenced by spatial and temporal dependency, and the availability of European Union “cohesion” investments intended to address economic inequality and promote sustainable development. The findings advance our understanding of the complexity of urban land-use patterns and sustainability goals.

As climate change challenges the sustainability of existing water supplies, many cities must transition toward more sustainable water management practices to meet demand. However, scholarly knowledge of the factors that drive such transitions is lacking, in part due to the dearth of comparative analyses in the existing transitions literature. This study seeks to identify common factors associated with transitions toward sustainability in urban water systems by comparing transitions in three cases: Miami, Las Vegas, and Los Angeles. For each case, we develop a data-driven narrative that integrates case-specific contextual data with standardized, longitudinal metrics of exposures theorized to drive transition. We then compare transitions across cases, focusing on periods of accelerated change (PoACs), to decouple generic factors associated with transition from those unique to individual case contexts. From this, we develop four propositions about transitions toward sustainable urban water management. We find that concurrent exposure to water stress and heightened public attention increases the probability of a PoAC (1), while other factors commonly expected to drive transition (e.g. financial stress) are unrelated (2). Moreover, the timing of exposure alignment (3) and the relationship between exposures and transition (4) may vary according to elements of the system’s unique context, including the institutional and infrastructure design and hydro-climatic setting. These propositions, as well as the methodology used to derive them, provide a new model for future research on how cities respond to climate-driven water challenges.

Although the water management sector is often characterized as resistant to risk and change, urban areas across the United States are increasingly interested in creating opportunities to transition toward more sustainable water management practices. These transitions are complex and difficult to predict – the product of water managers acting in response to numerous biophysical, regulatory, political, and financial factors within institutional constraints. Gaining a better understanding of how these transitions occur is crucial for continuing to improve water management. This paper presents a replicable methodology for analyzing how urban water utilities transition toward sustainability. The method combines standardized quantitative measures of variables that influence transitions with contextual qualitative information about a utility's unique decision making context to produce structured, data-driven narratives. Data-narratives document the broader context, the utility's pretransition history, key events during an accelerated period of change, and the consequences of transition. Eventually, these narratives should be compared across cases to develop empirically-testable hypotheses about the drivers of and barriers to utility-level urban water management transition. The methodology is illustrated through the case of the Miami-Dade Water and Sewer Department (WASD) in Miami-Dade County, Florida, and its transition toward more sustainable water management in the 2000's, during which per capita water use declined, conservation measures were enacted, water rates increased, and climate adaptive planning became the new norm.
