European countries, especially urban areas, face increasing flood risks due to urbanization, increase of exposure and damage potential, and the effects of climate change. In literature and in practice, it is argued that a diversification of Flood Risk Management Strategies (FRMSs) makes countries more flood resilient. The latter requires innovations in existing Flood Risk Governance Arrangements, development of new arrangements and the coordination of these arrangements, but it also requires these arrangements to be tailored to their physical and institutional context. Within the EU FP7 project STAR-FLOOD (2012-2016), a comparative analysis and evaluation of flood risk governance in Belgium, England, France, The Netherlands, Poland and Sweden has been conducted. The project identified at least seven key issues that are relevant for all researched countries (and probably also beyond). These key issues deal with the topics of (i) diversifying Flood Risk Management Strategies (ii) establishing connectivity between actors, levels and sectors through what we coin “bridging mechanisms” (iii) achieving coproduction between public and private actors; (iv) improving fragmented and often non-enforceable rule systems; (v) optimising available resources for FRM; (vi) operationalising the notion of “diversification of FRM strategies” in a country-specific way; (vii) follow general design principles for improving FRM that are sufficiently tailored to local circumstances. Drawing on all project deliverables, this paper will briefly review each key issue, discuss salient similarities and differences between the countries and point at ways forward.
