Current European Union (EU) policies require policy-makers on different levels of government to engage with new forms of governance such as participatory planning, aiming to improve environmental policy delivery. We address the central issue of how policy-makers learn about the appropriateness of different modes of governance. By way of example, we examine recent innovations in EU water governance – primarily through the enactment of the Water Framework Directive (2000) and the Floods Directive (2007), and their requirements for stakeholder participation in the planning process. We discuss scope for policy-induced ‘governance learning’, wherein policy-makers draw on evidence and experience to learn about how to design and execute effective participatory planning and decision-making. In doing so, we aim to extend work on policy learning by focusing on the procedural dimensions of governance, and make a case for more coordinated and systematic approaches to gathering evidence and learning from ongoing EU environmental policy implementation.
