Abstract
Nature-based flood defences (NBFD) can be an alternative to hard flood protection. Hard flood protection measures like dams and dikes pose different drawbacks such as costly maintenance and unsustainable heightening. NBFD is an overarching term for different flood defence techniques that make use of natural dynamics to contribute to flood protection. Research on governance arrangements and institutions of NBFD implementation is limited. The goal of this research is to understand the working of governance arrangements and the institutional setting for NBFD implementation and to make recommendations to enable the NBFD implementation. A conceptual framework explains the influence of governance arrangements and institutions on the implementation of NBFD. The conceptual framework combines interaction oriented policy research by Scharpf (1997), the seven institutional rules-in-use by Polski and Ostrom (1999) and applications of game theory (Osborne & Rubinstein, 1994; Rasmusen, 2007; Schelling, 2010). Based on the conceptual framework a multiple case study research is conducted. For three Dutch cases crucial factors for NBFD implementation are identified: Marker Wadden, Hondsbossche and Pettemer sea defence (HPSD) and fort Steurgat. For these cases the crucial factors enabling NBFD implementation are analysed by considering actors, actor-interaction (games) and institutions.
