Fragmentation across scales in natural resource governance can impede coordinated action and decrease innovation capacity. Bridging actors who connect others within governance networks helps to overcome this challenge. We analyze two bridging positions for actors in governance networks. First, periphery connectors integrate otherwise unconnected actors and provide access to new knowledge. Second, central coordinators efficiently connect actors at the center of the network and thus facilitate coordinated action. We propose a way to identify periphery connectors and central coordinators within governance networks and formulate expectations about types of actors that are likely to occupy these positions. An analysis of three actor networks in the water supply sector in Switzerland suggests that periphery coordinator positions are more likely to be occupied by organizations at higher jurisdictional levels. Central coordinator positions are more likely to be occupied by governmental actors as compared to nongovernmental actors. Thus, in addressing challenges of fragmentation, higher level governmental actors continue to play an important role, even when they delegate responsibilities to lower level and private actors.

We address a key puzzle in policy studies: why don't major differences in political systems and policy produce major differences in policy processes, outputs, and outcomes? We show why key aspects of fracking policy are similar in the UK and Switzerland despite the UK majoritarian government being 'all out for shale' and Switzerland’s consensus democracy favouring moratoriums. We use the 'advocacy coalition framework' and new survey data to show why differences in UK and Swiss processes are subtle. In both cases, actors cooperate and compete with each other by sharing information within and across coalitions.

In water-scarce regions of China, wastewater reuse is increasingly considered as a potential component of China's future water resource management strategy. Currently, the percentage of wastewater reuse varies substantially across Chinese provinces, but conditions leading to a high rate of wastewater reuse have not been elucidated clearly. In this work, we use fuzzy-set qualitative comparative analysis (fsQCA) to identify the drivers of high and low percentages of wastewater reuse in water-stressed Chinese provinces in 2013. We find that among the five conditions studied (per capita water availability, urban population, access to sea, access to urban space, and access to agricultural land), a high percentage of wastewater reuse is primarily driven by water stress and access to urban green space. Consequently, policies should consider targeting provinces with these attributes where wastewater reuse is more likely to be successful. Further, our results show that there is asymmetry in the conditions that lead to high and low percentages of wastewater reuse, and that the drivers for and against reuse identified in this study are not completely analogous to those identified in previous studies. As such, the drivers for and against wastewater reuse should not be generalized without due consideration of the local context.

New techniques of unconventional oil and gas extraction, such as hydraulic fracturing, challenge current political, institutional and administrative practices in how to regulate activities in the underground. Conflicts of interests between economic promotion, landscape and natural resource protection, and new trends on energy markets are further intensified by the fact that techniques of oil and gas extraction come with a considerable amount of uncertainties regarding ecological and health impacts. Information exchange is one important aspect of how political actors try to reduce uncertainties and conflicts. Based on exponential random graph models (ERGM) for network data, we analyze to what degree ideologies, public authority, existing collaboration and scientific expertise drive information exchange in hydraulic fracturing regulation in the United Kingdom. Results show that technical and political information exchange have to be disentangled, and that the former is driven by expertise and existing collaboration, the latter by ideology, public authority and existing collaboration.

In polycentric governance systems, actors interact in different venues, such as forums which foster cross-sectoral interaction. This analysis centres on water forums in Switzerland and on actors with multiple forum memberships, creating interactions throughout the entire forum network. Findings show that the central actors in the entire water forum network are predominantly from the public administration sector, even though members from the private sector are most numerous. Despite an emphasis on the bottom-up and self-organizing character of polycentric governance systems in the literature, this analysis shows that public administration actors still play a crucial role as network managers and brokers.

Policy forums are lightly institutionalized and stable forms of governance networks that include administrative authorities, interest groups, and scientists. They are said to produce different types of outputs, from simple actor coordination to position papers and implementation documents, but their productivity has also been questioned. Metagovernance strategies can improve the capability of policy forums to produce outputs. To determine how different metagovernance strategies influence the capability of forums to produce joint position papers, 29 policy forums in the Swiss environmental sector are compared through a qualitative comparative analysis. Results indicate that metagovernance strategies such as state actors as forum members or majority decision rules need to be combined with small forum size or low actor heterogeneity. Furthermore, forum foundation by the state complicates the production of position papers.
