In order to tackle the challenge of rising flood risk and to develop effective policies and risk management practices, policy-makers and key stakeholders need a strong evidence base. Evidence-based policy-making is the key to modern, forward-looking strategies for dealing with increasing flood risk. Trans-boundary and trans-national flood risk management issues are becoming more and more important, requiring in particular joint research and development initiatives. The creation and implementation of a European research area in flood risk management – as intended by the CRUE ERA-Net - is an important contribution to an improved trans-national perspective for flood-related research in Europe. Besides co-ordinating research between Member States, CRUE aims to contribute towards the presentation of research needs with its own trans-nationally based funding initiatives. Common trans-national research calls initiated by the partner countries are a principal activity within the CRUE ERA-Net which can be considered as specific actions to respond to current policy and development needs in Europe. With the launch of the first CRUE common call, a first step toward the integration of flood research in Europe was made. The topic “Risk Assessment and Risk Management: Effectiveness and Efficiency of Non-structural Flood Risk Management Measures” was selected by six of the CRUE partner countries through an intensive consultation process and is to a great extent based on developments in European flood risk management policy (e.g. EU Floods Directive). In particular, the call was designed to investigate and critically assess the effectiveness and efficiency of non-structural measures in comparison to structural measures and to identify barriers to implementation of these "soft" techniques. The call was an incentive to develop innovative methodological approaches. Moreover, it challenged researchers across Europe to integrate knowledge across different disciplines such as natural and social sciences, and engineering. Each of the seven successful joint projects within CRUE’s 1st Funding Initiative for FRM research was designed to understand different national approaches to the use and appraisal of non-structural measures, explore what is successful, and what can be improved in terms of efficiency and effectiveness of such measures themselves. The research results presented in this report will provide policy-makers with a better understanding of how FRM as a part of integrated river basin management can deliver multiple benefits, for example reduced flood risk and improved environmental quality. I feel confident that the outcome of this research will be a valuable contribution to national policy development and the improvement of flood risk-related practice. John Goudie ERA-Net CRUE Co-ordinator, Defra, UK IV CRUE FUNDING INITIATIVE ON FLOOD RISK MANAGEMENT RESEARCH FLOOD-ERA Summary for Decision Makers FLOOD-ERA deals with the systematisation, evaluation and comparison of structural measures (SM) and non-structural measures (NSM) and takes context conditions of decision making on both types of measures like risk perception, funding mechanisms, and formal institutions into account. The study is important because up to now there is considerable uncertainty about how NSM can be compared with SM in a consistent way with regard to advantages and disadvantages. The overall aim of the project is to make important steps towards preventive flood risk management strategies in European Member States through (i) improving the comparative evaluation of structural (SM) and non-structural measures (NSM) and through (ii) analysing the influence of context conditions (like risk perception of decision makers) on the choice of measures. FLOOD-ERA begins with the assumption that current flood risk management (FRM)
