Does stakeholder participation improve environmental governance? Evidence from a meta-analysis of 305 case studies.

Participation and collaboration of citizens and organized stakeholders in public decision-making is widely believed to improve environmental governance outputs. However, empirical evidence on the benefits of participatory governance is largely scattered across small-N case studies. To synthesize the available case-based evidence, we conducted a broad case-based meta-analysis across 22 Western democracies, including 305 individual cases of public environmental decision-making. We asked: How do 'more' participatory decision-making processes compare against 'less' participatory ones in fostering - or hindering - strong environmental governance outputs, (i.e. environmental provisions in plans, agreements or permits)? Which design features make a difference? What role does the decision-making context play? How do results change if we control for the intentions of the leading governmental agency? To capture the central design features of decision-making processes, we distinguish three dimensions of participation: the intensity of communication among participants and process organizers; the extent to which participants can shape decisions ("power delegation"); and the extent to which different stakeholder groups are represented. Our regression analysis yields robust evidence that these three design features of participation impact upon the environmental standard of governance outputs, even when controlling for the goals of governmental agencies. Power delegation is shown to be the most stable predictor of strong environmental outputs. However, communication intensity only predicts the conservation-related standard of outputs, but not the environmental health-related standard of outputs. Participants' environmental stance was another strong predictor, with considerable variation across different contexts. While our results remain broadly stable across a wide range of contexts, certain contextual conditions stood out in shaping the relation between participation and environmental outputs. Overall, our findings can inform the design of participatory processes that deliver governance outputs of a high environmental standard.

Case study meta-analysis in the social sciences. Insights on data quality and reliability from a large-N case survey.

Meta-analytical methods face particular challenges in research fields such as social and political research, where studies often rest primarily on qualitative and case study research. In such contexts, where research findings are less standardized and amenable to structured synthesis, the case survey method has been proposed as a means of data generation and analysis. The method offers a meta-analytical tool to synthesize larger numbers of qualitative case studies, yielding data amenable to large-N analysis. However, resulting data is prone to specific threats to validity, including biases due to publication type, rater behaviour, and variable characteristics, which researchers need to be aware of. While these biases are well known in theory, and typically explored for primary research, their prevalence in case survey meta-analyses remains relatively unexplored. We draw on a case survey of 305 published qualitative case studies of public environmental decision-making, and systematically analyze these biases in the resultant data. Our findings indicate that case surveys can deliver high-quality and reliable results. However, we also find that these biases do indeed occur, albeit to a small degree or under specific conditions of complexity. We identify a number of design choices to mitigate biases that may threaten validity in case survey meta-analysis. Our findings are of importance to those using the case survey method - and to those who might apply insights derived by this method to inform policy and practice.

Participation for effective environmental governance? Evidence from Water Framework Directive implementation in Germany, Spain and the United Kingdom.

Effectiveness of participation in environmental governance is a proliferating assertion in literature that is also reflected in European legislation, such as the European Water Framework Directive (WFD). The Directive mandates participatory river basin management planning across the EU aiming at the delivery of better policy outputs and enhanced implementation. Yet, the impact of this planning mode in WFD implementation remains unclear, though the first planning phase was completed in 2009 and the first implementation cycle by the end of 2015. Notwithstanding the expanding body of literature on WFD implementation, a rather scattered single case study approach seems to predominate. This paper reports on implementation of the WFD in three case studies from Germany, Spain and the United Kingdom, reflecting three substantially different approaches to participatory river basin management planning, on the basis of a comparative case study design. We ask if and how participation improved the environmental standard of outputs and the quality of implementation. We found an increasing quality of outputs with increasing intensity of local participation. Further, social outcomes such as learning occurred within dialogical settings, whereas empowerment and network building emerged also in the case characterized mainly by one-way information. Finally, one important finding deviant from the literature is that stakeholder acceptance seems to be more related to processes than to outputs.

Exploring governance learning: How policymakers draw on evidence, experience and intuition in designing participatory flood risk planning.

The importance of designing suitable participatory governance processes is generally acknowledged. However, less emphasis has been put on how decision-makers design such processes, and how they learn about doing so. While the policy learning literature has tended to focus on the substance of policy, little research is available on learning about the design of governance. Here, we explore different approaches to learning among German policymakers engaged in implementing the European Floods Directive. We draw on official planning documents and expert interviews with state-level policymakers to focus on learning about the procedural aspects of designing and conducting participatory flood risk management planning. Drawing on the policy learning and evidence-based governance literatures, we conceptualise six types of instrumental 'governance learning' according to sources of learning (endogenous and exogenous) and modes of learning (serial and parallel). We empirically apply this typology in the context of diverse participatory flood risk management planning processes currently unfolding across the German federal states. We find that during the first Floods Directive planning cycle, policymakers have tended to rely on prior experience in their own federal states with planning under the Water Framework Directive to inform the design and carrying out of participatory processes. In contrast, policymakers only sporadically look to experiences from other jurisdictions as a deliberate learning strategy. We argue that there is scope for more coordinated and systematic learning on designing effective governance, and that the latter might benefit from more openness to experimentation and learning on the part of policymakers.
