Learning in Polycentric Governance: Insights from the California Delta Science Enterprise

by Tara Pozzi, Mark Lubell, Tanya Heikkila, Andrea K. Gerlak, & Pamela Rittelmeyer

Science enterprises play an increasingly important role in shaping the policy process. While existing literature explores the nexus of science and decision-making, research is limited by a lack of empirical institutional analysis—specifically how science is shaped by and a feature of governance institutions. To address this gap, we integrate the ecology of games framework (EGF) and collective learning framework (CLF) to examine how polycentric systems of science actors and forums influence policy-relevant learning. This exploration is guided by three types of hypotheses to account for diverse actors:

  1.  Individual-level hypotheses consider how organizational affiliation, professional involvement, forum participation, and expertise on diverse issues of individual actors participating in a science enterprise may shape perceived learning.
  2. Forum-level hypotheses consider how variance in forum social dynamics, institutional structure, and functional domain characteristics may shape perceived learning.
  3. The learning stage hypothesis suggests that the perceived level of learning will be lower at later stages of the adaptive management cycle.

In 2021, we conducted a survey of science actors involved in managing and governing the California Delta. The survey participants were individuals who produce, interpret, or use science for Delta policymaking, including academics, government agency officials, and nonprofit and community representatives. Respondents were identified through a purposive sampling, using the Delta Science Program to disseminate the survey electronically to numerous listservs. The survey measured core perceptions of the regional science forums, such as extent of professional involvement and participation, expertise of diverse issues, leadership effectiveness, representative engagement, coordination, resources, and forum purpose.

To analyze the data, we estimated four generalized linear multi-level models using Bayesian methods. The models analyze the effect of individual- and forum-level variables on perceived learning across different science forums, with a separate model for a composite scale and each stage of the adaptive management cycle.

As illustrated in Figure 5, the social and institutional attributes of science forums are the most important drivers of learning, relative to the human and financial capital attributes of the forums or the level of individual actor engagement. For example, the variables of leadership, trust, and coordination consistently have the largest positive influence on all learning stages of adaptive management, whereas the resources variable is consistently less positive. This finding suggests that administrative and financial resource limitations are less important for learning than social drivers.

Through integrating two policy process frameworks, we have created a new theoretical basis for analyzing policy-related learning within polycentric governance systems. Our Bayesian approach allowed us to visualize the changing importance of social dynamics versus administrative resources across developmental stages of scientific forums. As polycentric systems grow over time, resources pose less limitations on their effectiveness. Our forum-level results also reaffirm findings in a comparative case study that social capital plays an important role in policy-related learning. The findings shed light on how science shapes and is shaped by the policy process, providing valuable insights into how policy-relevant learning occurs in polycentric governance systems.

Partisan Collaboration in Policy Adoption: An Experimental Study With Local Government Officials

by Yixin Liu

Collaboration among local governments is crucial for tackling shared challenges like environmental management and economic development. Partisanship significantly shapes these collaborative efforts. In my recent paper, I investigate how partisanship affects local policymakers’ decisions to collaborate and whether political identity moderates the importance of key collaborative attributes like resource allocation, reciprocal trust, and policy outcomes. This work bridges gaps in the existing collaborative strategies literature by focusing on individual-level preferences rather than aggregated patterns.

This study sought to address two primary research questions:  

(1) Does partisanship influence local policymakers’ willingness to adopt collaborative sustainable development programs?  

(2) Does partisanship alter how policymakers weigh other collaborative attributes, such as trust or resource sharing, in their decision-making?  

To test these questions, I designed a conjoint experiment targeting municipal officials across the United States. Participants were asked to evaluate hypothetical sustainable development programs proposed by cities with varying partisanship and collaborative attributes—such as the balance of resource contributions (resource allocation), the expected number of jobs created by the program (policy outcome), and past collaborations with the partner city (reciprocal trust). By randomizing these attributes, I was able to isolate the effect of partisanship while controlling for other factors.  

Image Description

The sample included 772 local government officials, representing a broad cross-section of U.S. municipalities. These officials represented 535 municipalities and covered offices from 49 states and the District of Columbia. I used my data to test two hypotheses:

Co-­partisanship Hypothesis (H1): The collaborative program proposed by co-partisans will increase the interest of municipal officials in adopting it, compared to the same program proposed by out-­partisans.

Conditional hypothesis (H2): The importance of resource allocation, reciprocal trust, and policy outcomes will weaken if the collaborative program is not proposed by co-­partisans.

Image Description

The co-partisanship effect was clear: Programs proposed by co-partisans were 12.75 percentage points more likely to be adopted than those proposed by out-partisans, supporting H1 (see Figure 2). Moreover, my analysis yielded support for H2. My results showed that the influence of collaborative attributes was indeed conditional on whether it was proposed by a co-partisan. For example, respondents favored programs that required lower resource contributions or had higher job creation potential, but these attributes were weighed less heavily when the proposal was made by a partner city in the out-party (see Figure 3). It is also important to note that the influence of partisanship was consistent across subgroups, suggesting its deep roots in political identity rather than professional roles or ideologies.

Image Description

This study highlights the importance of understanding the role of partisanship in collaborative governance. Future research could explore the long-term impacts of partisanship on collaborative governance or expand the scope to other policy areas. Additionally, combining experimental methods with observational data could enhance our understanding of how partisan dynamics evolve over time in real-world settings.

External drivers of participation in regional collaborative water planning

by Emily V. Bell, Amanda Fencl, & Megan Mullin

Collaborative governance has gained significant attention in recent years, particularly in understanding why stakeholders choose to engage—or not engage—in these processes. At its core, collaborative governance involves multilateral decision-making, where diverse participants collectively identify and address shared problems, seeking consensus on public policy decisions. These processes typically occur within “collaboratives,” which are designed to represent the needs of interconnected stakeholders aiming to solve a common issue.

One prominent area of research in collaborative governance draws on transaction cost theory. This perspective examines whether the benefits of participating in a collaborative outweigh the costs, especially considering potential cooperation challenges and unequal distribution of benefits. Recent studies, however, have expanded this focus to explore the external drivers of cooperation among stakeholders, such as perceived risks of future hazards and systemic capacity. 

Our research focuses on the participation of public water systems (PWSs) in collaborative planning for regional water governance. We hypothesize that perceived risks, defined as beliefs held by water system decision makers about the potential for a harmful event to occur (e.g., droughts, reduced precipitation, insufficient supply, etc.), often prompt collaborative action, especially when they result in collective, interconnected problems. Moreover, we suspect that system capacity—which includes technical, managerial, and financial resources—influences participation by constraining behavior or establishing means necessary for collaboration. We propose three hypotheses:

H1: Actors perceiving greater risk of future hazards will be more likely to participate in regional collaborative planning.

H2: Actors perceiving future demand that exceeds ability to provide public services will be more likely to participate in regional collaborative planning.

H3: Actors with higher capacity will be more likely to participate in regional collaborative planning.

Figure 1. Reported concern for future drought, reduced precipitation, and demand on water supplies in California and North Carolina, respectively.

To test these hypotheses, we analyzed data from California and North Carolina. These states provide an opportunity to investigate collaborative participation in two differing political and institutional contexts. Using binomial logistic regression models, we found support for hypotheses 1 and 3. In other words, the data suggests that an increase in perceived risks and system capacity increases the likelihood of participation in collaborative governance. Our results, however, showed little support for hypothesis 2.

Figure 2. Frequency of system participation in regional planning by system size and state, where the frequency summed is 100% of respondents per state.

This study takes a crucial step toward understanding the role of contextual and external factors in decisions to participate in collaborative governance. By shifting focus outward, it aims to enrich our knowledge of why governance stakeholders engage, complementing existing research on forum-focused perceptions and social dynamics. While previous work has explored interpersonal relations and externalities, this study emphasizes the need for a closer, systematic evaluation of institutional and biophysical contexts. Although participation alone may not guarantee effective collaboration, understanding what motivates stakeholders to join these processes is vital for fostering meaningful engagement.

Manifesting Symbolic Representation through Collaborative Policymaking

by Jack Mewhirter, Danielle McLaughlin, & Brian Calfano

Representation is crucial to any collaborative governance arrangement. The makeup of those who participate in collaborative forums impacts not just who “wins” and “loses” in the policymaking process, but also how the public perceives participating organizations. Generally speaking, if citizens feel that their interests and incentives are being represented by those participating in a collaboration, they will hold more positive beliefs toward those organizations involved, a phenomenon referred to as “symbolic representation.” Conversely, a perceived lack of representation can potentially engender distrust and negative perceptions toward participating organizations.

The inclusion of civil society organizations in collaborative policymaking is crucial to making citizens feel represented in collaborative forums. Compared to, for example, business and government stakeholders, civil society organizations tend to be more embedded in local communities and thus more responsive to their wants and needs. Thus, we argue that collaborative policymaking forums that feature high participation from civil society organizations should produce a symbolic effect toward participating organizations for citizens aware of this representation.

We test this hypothesis in the context of the Collaborative Settlement Agreement (or CA) governing policing in Cincinnati, Ohio. Established following the controversial killing of a Black teenager in 2001, the CA created a collaborative forum that brought together the Cincinnati Police Department and civil society organizations to address concerns around policing. The CA is a good case study for our hypothesis because civil society organizations have been well-represented and very active within the forum, using it to bring about numerous reforms to department practices.

To capture respondents most representative of Cincinnati’s urban core, we conducted surveys at several community events in the city of Cincinnati between June and September 2017. We asked respondents about their familiarity with the CA and their subsequent feelings toward the Cincinnati Police Department, anticipating that the two will be positively related (i.e., those who are more knowledgeable about the CA will feel more warmly towards the police). We also asked a number of demographic and personal history questions (e.g., regarding race, age, income, any interactions with police, etc.) to see how such variables might correlate with respondents’ knowledge and attitudes. 

And indeed, we found a strong positive relationship between knowledge about the CA and attitudes towards the police. In our survey we also asked respondents to indicate whether they thought that Cincinnati police officers “looked like” them – otherwise referred to as “passive representation” – and found that those who agreed also felt more positively about the police. Other variables that showed positive correlations included age, employment, and income. 

Our study demonstrates the important role that representation in collaborative policymaking forums can play in how people feel about those who participate in it. The case of the Collaborative Agreement in Cincinnati particularly illustrates how the inclusion of civil society organizations can contribute to feelings of symbolic representation, an important finding in the context of police-community relationships. Our findings point to the need to involve groups with close community ties in collaborative policymaking endeavors, as this will go a long way to securing buy-in and coproduction from the broader population. Our findings also reinforce that passive representation – having participants in forums who “look like you” – can bolster symbolic representation. While the CA is a powerful example of inclusion and representation done well, further studies need to be done to see whether collaborative forums that don’t feature robust involvement from civil society organizations are indeed looked upon less favorably. Furthermore, our study took for granted that citizens feel represented by civil society organizations, but this assumption requires empirical testing as well.

Birds of a Feather Fight Together: Forum Involvement in a Weakly Institutionalized Ecology of Policy Games

by Tomás Olivier & Ramiro Berardo

Policy forums play a crucial role in polycentric governance because they can facilitate collective action among diverse actors who are invested in a policy domain. Many of these arguments assume that forums are stable over time and that they attract actors with different ideas or interests. But, what happens in unstable policy settings where forums operate in a context of periodic rule change and limited enforcement?  To answer this question, we look at how policy forums can facilitate interactions among actors with different perceptions about collective action challenges regarding water governance in Patagonia, Argentina. 

Forums can facilitate collective action by attracting actors with different perceptions about policy problems. This fosters interactions among actors who would otherwise not interact, potentially facilitating collaboration and the generation of new insights about how to solve joint problems. 

We study water governance in the Lower Valley of the Chubut River, located in Argentina’s Patagonia region. In 2017 and 2018, we surveyed 58 individuals from 34 different stakeholder groups, including government entities, private companies, and researchers. Our survey presented stakeholders with various scenarios regarding water governance in the Lower Valley and asked them to rate the extent to which they saw the scenarios as accurate or inaccurate. We also asked them about their perceptions of the forums overseeing water governance in the Lower Valley (e.g., whether they were fair, effective, etc.) and environmental conditions in the basin.  

We found that out of the 31 active forums in the Lower Valley, many were attended by just one stakeholder. Furthermore, we observed that government entities do not appear to be very active in these forums, preferring to operate outside of them as needed. Part of the reason for low participation is that the forums in the Lower Valley tend to be short-lived, formed to tackle a specific problem or crisis and then dissolved shortly thereafter. 

Most importantly, we found that actors who participate in the same forums tend to have similar perceptions about the dominant collective action problem in the region. This finding is meaningful from a governance perspective: in a context of high transaction costs, forums may serve as the first space where actors with similar perceptions may build the necessary commitments to engage in collective action. These forums can be problematic, as the range of views represented in them on how to solve a problem are limited. However, a silver lining is that they can also foster collaboration among actors who would otherwise may be distrustful of one another.

Our study deepens our understanding of how actors may organize to address complex policy problems in a context of weak institutions, and argues that the stability of forums in time is key to maintaining consistent stakeholder participation, a necessary condition for the solution of system-wide environmental problems.

Mitigating conflict with collaboration: Reaching negotiated agreement amidst belief divergence in environmental governance

by Elizabeth A. Koebele & Deserai Anderson Crow

Conflict is a natural part of democratic processes. However, understanding what drives conflict – and how it can be mitigated to a level where negotiation can occur – is essential for fostering productive policy making.

The Advocacy Coalition Framework (ACF) argues that policy conflict is fundamentally driven by belief divergence among coalitions, or groups of policy actors who share beliefs about a policy subsystem and coordinate to achieve their goals. It makes sense, then, that bringing coalitions’ beliefs closer together may also reduce conflict. However, the ACF warns that beliefs are hard to change, especially in high-conflict settings where actors are prone to biased assimilation of information, the devil-shift, and other tendencies that exacerbate conflict.

Collaborative governance is touted as a way to reduce policy conflict under such circumstances by encouraging diverse policy actors to engage in sustained, consensus-oriented deliberation around a shared problem. While collaborative governance may foster some level of belief convergence through information sharing and collective learning, it may also encourage opposing coalitions to negotiate through other mechanisms. For example, as they participate in a collaborative process, coalitions may come to better understand one another’s needs over time, build trust and mutual respect, and support collaborative institutions they perceive to be fair, even as they maintain unique beliefs.

To better understand the relationship between beliefs, conflict, and negotiation, we empirically analyze how two adversarial coalitions’ beliefs changed as they participated in a collaborative water governance process in Colorado, U.S., over the course of a decade. While the collaborative process ended in negotiated agreement, our analyses of longitudinal survey and interview data show that the coalitions’ beliefs actually diverged more at the end of the process than they did at the start – a finding contrary to what we would expect if negotiation was driven primarily by belief convergence.

We then identify several other aspects of the collaborative process and broader policy context that facilitated negotiation among the coalitions. Most importantly, societal value shifts, process norms that institutionalized actor roles and encouraged “multi-purpose” solutions, and the development of respect and social capital among actors appear to have promoted successful negotiation amidst belief divergence. We also found that the trend toward greater belief divergence was primarily attributed to one coalition strengthening their own unique beliefs over time while the other coalition’s beliefs remained fairly stable throughout the process.

Our results demonstrate that while belief divergence was likely a driver of conflict in this policy process, collaborative governance helped adversarial policy actors identify places where they could agree on, or at least consent to, common solutions over time. These findings have important implications for how collaborative processes can be designed to mitigate conflict among opposing coalitions and encourage future research on who changes their beliefs, how, and why while participating in a collaborative process. Scholars should also examine how collaborative governance affects different policy beliefs in different ways, which can help support the development of a more robust typology of beliefs in the ACF literature.

Drivers of (In)equity in Collaborative Environmental Governance

by Kristin Babson Dobbin

In recent decades, collaborative governance has reshaped environmental policy by encouraging horizontal cooperation among stakeholders in an effort to create more mutually beneficial, locally appropriate policies. However, despite its potential advantages, there is a lack of empirical evaluation of the approach, particularly regarding equity. Our study focuses on California’s groundwater management overhaul, known as the Sustainable Groundwater Management Act (SGMA), to examine the conditions under which equity is or is not promoted in collaborative processes.

The chronic groundwater management challenges in California, especially in the San Joaquin Valley, contribute to the state’s widespread drinking water inequities disproportionately affecting low-income rural communities. The severe drought from 2012 to 2016 exacerbated these issues, leading to the implementation of SGMA. Under SGMA, local agencies formed Groundwater Sustainability Agencies (GSAs) to manage groundwater and develop Groundwater Sustainability Plans (GSPs) addressing undesirable groundwater outcomes. Our study analyzes GSPs in critically overdrafted basins to assess their impact on vulnerable drinking water users and environmental justice communities.

We derive five hypotheses for factors influencing equity in collaborative governance derived from the existing literature— the extent of collaboration, representation, elite capture, stakeholder engagement, and problem severity/salience. We then test these hypotheses using Boosted Regression and Classification Trees (BRCT) comparing results across three models, each with a distinct measure of drinking water equity used as the dependent variable. 

Across all three models, our results support the hypotheses, underscoring the importance of collaboration, representation, elite capture, stakeholder engagement, and problem severity/salience in influencing the distribution of benefits, costs, and risks for vulnerable drinking water users in groundwater plans(see Figure 1). Nonetheless, the raw change in the dependent variables associated with these factors is in most cases quite limited. For example, when moving from zero to eighty percent representation for drinking water users on the GSA board of directors, we only predict a six-percentage point increase in environmental justice rubric score from 40.65 to 46.60. Thus, we assert additional interventions beyond the scope of the factors studied herein are likely essential if we are to increase social equity in decentralized collaborative decision making. 

Comparing the influence of these five factors within and among the models lends additional important insights. Among them, our findings suggest that it might be easier to improve equity in the distribution of collaborative governance benefits than in the distribution of risks or burdens. Also notable is that across equity measures, representation in decision-making roles is consistently more influential than traditional stakeholder engagement. Finally,  given that many of the estimated associations are nonlinear, our findings underscore the importance of addressing threshold effects and optima, rather than presence or absence, when seeking to advance specific collaborative outcomes.

Future research should focus on a nuanced understanding of local institutional design as well as the potential role of external linkages with outside organizations given that some research indicates they may increase accountability. Such work can help us understand the potential and limits of collaborative governance for ensuring positive environmental outcomes for all.
