Despite pressures to improve performance and reduce costs, innovation in the municipal wastewater sector in the United States has been notoriously slow. Previous research has suggested that wastewater utility managers may see regulation as a barrier to developing and deploying new technologies. To better understand how environmental regulation may fuel or hinder innovation in this sector, we conducted a nationwide survey of wastewater utility managers and wastewater regulators in the United States, asking both populations about their perceptions of specific aspects of regulation and innovation. Survey results revealed broad agreement between the two groups that funding and capacity, regulatory relationships, and complexities and inconsistencies within the regulatory environment present key barriers to and opportunities for enabling increased innovation in the municipal wastewater sector. While utility managers perceived almost all aspects of regulation as stronger barriers and opportunities than regulators did, both groups ranked them similarly. These results are promising evidence of common ground between wastewater regulators and municipal wastewater utility managers, and suggest shared views of key leverage points for encouraging innovation. Notably, neither regulators nor utility managers viewed reducing regulatory stringency as a productive way to encourage the deployment of new technologies. Rather, our survey results suggest that improving relationships and communication between utility managers and regulators, along with additional funding support for increased capacity of both utilities and regulators, would be more fruitful ways to encourage innovation in the municipal wastewater sector.

Water scarcity in the Western US, through the lens of political ecology, can be understood as inextricably shaped by power dynamics, governance structures, and legal practices of resource allocation. Water allocation in the region is determined largely by the legal doctrine of Prior Appropriation, the 'first in time, first in right' principle. However, prior appropriation is fundamentally based in anthropocentric and settler colonial assumptions, and in light of drought, climate change, and shifting social and environmental values, the system has been critiqued as inadequate to meet contemporary water challenges. Despite challenging historical legacies, water managers in the Western US are developing a range of strategies to work around or within prior appropriation to secure environmental flows for rivers and aquatic species. In this article we use political ecology and diverse economies approaches to consider the challenges of, and challenges to, prior appropriation. We examine a diverse set of practices, work-arounds, and creative strategies being used to secure instream flows, and discuss how these strategies affirm or challenge prior appropriation, how they reinforce or challenge inequities, and how they reform or re-envision water allocation in ways that may open up potential for social and environmental justice.

California's Sustainable Groundwater Management Act (SGMA), passed in 2014, recognizes and addresses connections between surface water and groundwater. The statute is California's first statewide law to explicitly reflect the fact that surface water and groundwater are frequently interconnected and that groundwater management can impact groundwater-dependent ecosystems, surface water flows, and the beneficial uses of those flows. As such, SGMA partially remedies the historically problematic practice of treating groundwater and surface water as legally distinct resources. SGMA requires groundwater sustainability agencies (GSAs) to manage groundwater to avoid six undesirable results, including significant and unreasonable adverse impacts on beneficial uses of surface water. While this aspect of SGMA is clearly important, significant uncertainties exist regarding how GSAs will actually define and achieve this goal. Addressing SGMA's requirements for groundwatersurface water interactions will be difficult. Defining the issues at stake in any given basin, let alone successfully balancing the range of uncertainties and potentially conflicting interests, will pose challenges for many GSAs. No clear, pre-defined formula exists to guide GSAs in determining what significant and unreasonable depletions of interconnected surface water will be, or whether planned actions will sufficiently avoid them. Yet they are required to do so. Many GSAs will face pressure to aggressively address impacts on surface water in their basin. Many will face equal or greater pressure not to draw the line. Nevertheless, it will fall to the GSAs to make a determination, and to defend it in their groundwater sustainability plans (GSPs). Therefore, GSAs will likely take on some level of risk—of successful political opposition to their GSP, of succesful legal challenges to their GSP, of their GSP performing ineffectively, or of all of these outcomes. Given the aggressive timeline inherent to SGMA, addressing this risk early will be crucial for preserving management options. Challenges and risk are not the whole story, however. The process of addressing groundwater-surface water interactions also offers GSAs an opportunity to help communities and other stakeholders resolve, or avoid, difficult conflicts, and to do so in lasting ways. While California law has only recently begun to seriously address conflicts between surface and groundwater uses, those conflicts have been occurring for decades, and in some places for over a century. SGMA, in other words, did not create conflict between groundwater pumping and beneficial uses of surface water; instead it created an opportunity—as well as an obligation—to respond to those challenges. Embracing that opportunity will not be easy, but GSAs that take SGMA as an opportunity to resolve longstanding issues can do lasting good. The research presented here examines some of the legal and institutional questions that will inevitably arise as GSAs seek to address groundwater-surface water interactions under SGMA. The core goal of this report is to help parties identify and address these questions, and ultimately to let GSAs and stakeholders manage groundwater-surface water interactions proactively and effectively.

Governments, utilities, and energy companies are increasingly looking towards energy storage technologies to extend the availability of variable renewable power sources such as solar and wind. In this Perspective, we examine these fast-shifting developments by mapping and analyzing landscapes of renewable energy storage emerging across the Western United States. We focus on the rollout of several interrelated leading technologies: utility-scale lithium-ion batteries, supported by increasing regional lithium mining, and proposals for new pumped storage hydropower. Drawing on critical resource geography, we examine energy storage as both a component of renewable transition and as its own driver of landscape transformation, resource extraction, and conflict. By mapping and interpreting emerging Western landscapes, we show that leading energy storage technologies and the materials needed to make them can require extensive surficial land use and have significant regional water impacts, and that they are generating opposition from groups concerned about environmental degradation and (in)justice. We propose an agenda for future research on energy storage aimed at rendering its development more socio-ecologically beneficial and just.

Rooted networks provide a conceptual framework that embeds network thinking in nature-society geography in order to investigate socio-ecological relations, while emphasizing the place-specific materiality of these relations. This progress report examines how geographers have put the framework into scholarly practice. The conceptual approach has enabled researchers to: 1) articulate the territoriality and materiality of networks as assemblages, which may be simultaneously rooted and mobile; 2) discern diverse types of power that flow through network connections; and 3) conduct analyses that unearth multiply-situated knowledges within networks. Challenges emerge as we seek to integrate the approach more fully with disciplinary traditions, including organizing complex relationships into bounded scholarly formats; choosing which aspects of the network are most salient to analyze; and illustrating networks for effective communication. We describe the ways in which rooted networks can be used as a tool for action, as a pedagogical guide, and to strengthen collective capacity to imagine and negotiate alternative futures based on 'seeing multiple.' Finally, we call for geographers and other scholars, researchers and activists to build upon a rooted networks framework as a tool for design, analysis, understanding and communication in the search for more socially just and ecologically viable futures.

We propose representation justice as a theoretical lens for socio-hydrology and water governance studies. An exploratory survey of 496 water sector employees in the United States revealed that self-identifying females felt more strongly discriminated against due to their gender and other social factors, compared to self-identifying males. Responses unveiled how macro- and microaggressions impede career pathways to leadership positions and, therefore, representation. We identify ways in which socio-hydrology can benefit from a representation justice lens by considering the following: (1) how power and politics shape the composition of the water sector and decision-making processes; (2) how available quantitative data do not account for lived experiences of individuals in the water sector; and (3) how intersectionality cannot easily be accounted for in current socio-hydrological models. We offer a representation justice research and water management agenda that goes beyond quota filling to include meaningful engagement with diverse groups, lenses, and knowledge.

Evidence-based environmental management requires data that are sufficient, accessible, useful and used. A mismatch between data, data systems, and data needs for decision making can result in inefficient and inequitable capital investments, resource allocations, environmental protection, hazard mitigation, and quality of life. In this paper, we examine the relationship between data and decision making in environmental management, with a focus on water management. We focus on the concept of decision-driven data systems—data systems that incorporate an assessment of decision-makers' data needs into their design. The aim of the research was to examine the process of translating data into effective decision making by engaging stakeholders in the development of a water data system. Using California's legislative mandate for state agencies to integrate existing water and other environmental data as a case study, we developed and applied a participatory approach to inform data-system design and identify unmet data needs. Using workshops and focused stakeholder meetings, we developed 20 diverse use cases to assess data sources, availability, characteristics, gaps, and other attributes of data used for representative decisions. Federal and state agencies made up about 90% of the data sources, and could readily adapt to a federated data system, our recommended model for the state. The remaining 10% of more-specialized data, central to important decisions across multiple use cases, would require additional investment or incentives to achieve data consistency, interoperability, and compatibility with a federated system. Based on this assessment, we propose a typology of different types of data limitations and gaps described by stakeholders. We also propose technical, governance, and stakeholder engagement evaluation criteria to guide planning and building environmental data systems. Data-system governance involving both producers and users of data was seen as essential to achieving workable standards, stable funding, convenient data availability, resilience to institutional change, and long-term buy-in by stakeholders. Our work provides a replicable lesson for using decision-maker and stakeholder engagement to shape the design of an environmental data system, and inform a technical design that addresses both user and producer needs.
