Abstract
This article contributes a boundary work analysis of the case of acid mine drainage (AMD) in South Africa to the existing boundary work literature. We conduct our analysis by applying a synthesized multi-level boundary work framework to examine whether the knowledge that was produced during the boundary work conducted was usable and influential in decision-making and resulted in successful policy implementation. We conclude that contrary to expectations, a closed, technocratic boundary work process resulted in the relatively successful implementation of a short-term intervention in the AMD problem, whereas a subsequent open and deliberative process did not result in the successful implementation of the long-term policy solution. We ascribe this finding to the influence of critical enabling and constraining factors characterizing the South African socio-political context within which the AMD issue is situated, and therefore, we recommend adding a meta-analytical layer to boundary work analyses, especially in developing country contexts.

This paper examines the complexity of the South African policy‐making context and its official and non‐official actors and investigates the challenges that scientists face when trying to exert their influence here in order to strengthen the science–policy interface. Based on this analysis, the paper makes preliminary recommendations on how scientists can venture to lobby policy‐makers in spite of the many obstacles they face. The main areas of interest in this paper are the science–policy interface, the policy‐making process and lobbying. Copyright © 2011 John Wiley & Sons, Ltd.

The Advocacy Coalition Framework (ACF) remains one of the leading conceptual models in the policy sciences because it continues to be revised and updated as required. A focus area of the ACF that requires further theorization is the roles of experts and expert-based information in influencing policy problem contexts. Our article takes a necessary step in this direction by (1) evaluating the usefulness of Weible's expectations regarding the uses of expert-based information in different types of policy subsystems and factors that contribute to shifts from one subsystem to another; and (2) making critical observations that result from this evaluation in the context of the controversial acid mine drainage policy case study in South Africa. The findings of our case study analysis indicate that Weible's framework performed reasonably well but also revealed opportunities for further improvement. We therefore suggest adding awareness raising as a use of expert-based information, developing a typology of different types of experts who participate in policy subsystems, and including a focus on the use of expert-based information in policy subsystem shifts. We also reflect upon the relevance and importance of continuing to expand ACF applications to countries outside of North America and Western Europe.
