This paper applies a policy analysis approach to the question of how to effectively regulate micropollution in a sustainable manner. Micropollution is a complex policy problem characterized by a huge number and diversity of chemical substances, as well as various entry paths into the aquatic environment. It challenges traditional water quality management by calling for new technologies in wastewater treatment and behavioral changes in industry, agriculture and civil society. In light of such challenges, the question arises as to how to regulate such a complex phenomenon to ensure water quality is maintained in the future? What can we learn from past experiences in water quality regulation? To answer these questions, policy analysis strongly focuses on the design and choice of policy instruments and the mix of such measures. In this paper, we review instruments commonly used in past water quality regulation. We evaluate their ability to respond to the characteristics of a more recent water quality problem, i.e., micropollution, in a sustainable way. This way, we develop a new framework that integrates both the problem dimension (i.e., causes and effects of a problem) as well as the sustainability dimension (e.g., long-term, cross-sectoral and multi-level) to assess which policy instruments are best suited to regulate micropollution. We thus conclude that sustainability criteria help to identify an appropriate instrument mix of end-of-pipe and source-directed measures to reduce aquatic micropollution.

Negotiated agreements are a promising pathway for policy change. This paper revisits and extends characteristics of negotiated agreements using the Advocacy Coalition Framework. We focus on two characteristics of negotiated agreements that previous literature has not explicitly addressed. First, we scrutinize the role of policy core and secondary policy beliefs in actor constellations. Secondly, we address partial success, that is, the notion that actors concede on some points, but in return succeed in others. We investigate these two characteristics in the 2014 reform of Swiss agricultural policy. Based on cluster and social network analysis, we exemplify how negotiated agreements embedded in a participatory policy process lead to a surprising level of policy change by promoting agricultural production practices with an intended positive effect on the environment. We show that rather than coalitions based on policy core beliefs, the formation of groups of actors based on secondary beliefs who span across the coalitions formed the basis for a negotiated agreement. Green and conservative groups were both able to achieve partial success. We conclude that insights from this exemplary case study should revive the concept and initialize a research agenda on negotiated agreements as a pathway for change in domestic policymaking.

In policymaking, actors are likely to take the preferences of others into account when strategically positioning themselves. However, there is a lack of research that conceives of policy preferences as an interdependent system. In order to analyse interdependencies, we link actors to their policy preferences in water protection, which results in an actor-instrument network. As actors exhibit multiple preferences, a complex two-mode network between actors and policies emerges. We analyse whether actors exhibit interdependent preference profiles given shared policy objectives or social interactions among them. By fitting an exponential random graph model to the actor-instrument network, we find considerable clustering, meaning that actors tend to exhibit preferences for multiple policy instruments in common. Actors tend to exhibit interdependent policy preferences when they are interconnected, that is, they collaborate with each other. By contrast, actors are less likely to share policy preferences when a conflict line divides them.

In times of increasing pressures on water resources, the integrated management of the resource is a central policy objective. While there exists encompassing research about the concept of integrated water resources management (IWRM), much remains to be studied regarding the integration of water-related policies. Water resources management profits when policy actors coordinate their demands and actions across policy sectors, territorial entities, and decision-making levels within a water basin. However, actors are bound by the policy framework, which organizes water resources management in defined sectors and, over time, develop into independent and specialized policy pillars. A growing number of policies increases the need to integrate those policies over time following the institutional resources regime (IRR) framework. However, an increasing number of policies also proves challenging in establishing an integrated, coherent regime compliant with IWRM. In this study, we analyze flood risk management policies and find an almost exponential increase in policies over time, while flood risks and damage have not decreased in parallel. We address this empirical puzzle with an in-depth analysis of the design of Swiss flood risk management policies over time. To this end, we survey the opinion of 146 flood experts on the importance of ten policy design indicators in three flood-prone regions in Switzerland. Flood risk management experts attribute particular importance to policy designs characterized by integration, a sufficient budget for policy implementation, and coercive instruments and sanctions. We then compare survey results to the ways in which Swiss policies have been designed in legislation across policy sectors related to flood risk management over the last 169 years. We find that policy designs follow a national policy style. Placing these results in local contexts, we explain why the design of policies represents both a challenge and opportunity for policy-makers involved in flood risk management.
