Although many policy process and diffusion theories follow the premise that scientific and technological knowledge plays a crucial role in a wide variety of policy fields, very few empirically assess the impact that institutional and process-relevant factors may have on the position of science within a process. The present study addresses the question of what role science plays in policy processes. To answer this, we apply the Advocacy Coalition Framework (ACF) and investigate three complementary assumptions using a qualitative comparison of four cases: the ACF claims that scientific experts can take very different positions in the policy process, depending on how conflictive or consensus-oriented the relations among actors and coalitions are within a so-called policy subsystem. Put differently, the type of subsystem impacts on the position of science within the process. The results show that subsystem-specific factors impact upon whether scientific representatives act at the periphery of a process or as policy brokers seeking feasible policy solutions.

Environmental problems are often multi-faceted and complex by nature, consisting of diverse, intertwined dimensions. In this article, we argue that environmental problem characteristics have consequences for the selection of appropriate governance modes, and finally on policy effectiveness. We rely on an in-depth literature review to proceed in two steps. First, we outline three key environmental problem characteristics: uncertainties, cause–effect mismatches and norm plurality. We then outline six different governance modes capable of producing policies and solutions to tackle challenges arising from the three problem characteristics. Next, through empirical illustrations, we demonstrate the relevance of linking governance modes to these characteristics via the introduction and articulation of the concept of ‘connectivity’, i.e., linking actors, issues, sectors and scale levels towards realizing effective policy solutions for complex environmental problems.

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.
