Flood Risk Perception

AbstractDespite an increasing number of people exposed to flood risks in Europe, flood risk perception remains low and effective flood risk management policies are rarely implemented. It becomes increasingly important to understand how local governments can design effective flood risk management policies to address flood risks. In this article, we study whether high flood exposure and flood risk perception correlate with the demand for a specific design of flood risk management policies. We take the ideal case of Switzerland and analyze flood risk management portfolios in 18 flood-prone municipalities along the Aare River. We introduce a novel combination of risk analysis and public policy data: we analyze correlations between recorded flood exposure data and survey data on flood risk perception and policy preferences for selected flood risk management measures. Our results indicate that local governments with high flood risk perception tend to prefer non-structural measures, such as spatial planning and ecological river restoration, to infrastructure measures. In contrast, flood exposure is neither linked to flood risk perception nor to policy preferences. We conclude that flood risk perception is key: it can decisively affect local governments’ preferences to implement specific diversified policy portfolios including more preventive or integrated flood risk management measures. These findings imply that local governments in flood-prone areas should invest in raising their population’s awareness capacity of flood risks and keep it high during periods without flooding.

The Subject

The application of natural and nature‑based features (NNBF) has grown steadily over the past 20 years, supported by calls for innovation in flood risk management (FRM) and nature‑based solutions from many different perspectives and organizations. Technical advancements in support of NNBF are increasingly the subject of peer‑reviewed and other technical literature. A variety of guidance has been published by numerous organizations to inform program‑level action and technical practice for specific types of nature‑based solutions. This effort to develop international guidelines on the use of NNBF was motivated by the need for a comprehensive guide that draws directly on the growing body of knowledge and experience from around the world to inform the process of conceptualizing, planning, designing, engineering, constructing, and operating NNBF.

Over Time

In times of increasing pressures on water resources, the integrated management of the resource is a central policy objective. While there exists encompassing research about the concept of integrated water resources management (IWRM), much remains to be studied regarding the integration of water-related policies. Water resources management profits when policy actors coordinate their demands and actions across policy sectors, territorial entities, and decision-making levels within a water basin. However, actors are bound by the policy framework, which organizes water resources management in defined sectors and, over time, develop into independent and specialized policy pillars. A growing number of policies increases the need to integrate those policies over time following the institutional resources regime (IRR) framework. However, an increasing number of policies also proves challenging in establishing an integrated, coherent regime compliant with IWRM. In this study, we analyze flood risk management policies and find an almost exponential increase in policies over time, while flood risks and damage have not decreased in parallel. We address this empirical puzzle with an in-depth analysis of the design of Swiss flood risk management policies over time. To this end, we survey the opinion of 146 flood experts on the importance of ten policy design indicators in three flood-prone regions in Switzerland. Flood risk management experts attribute particular importance to policy designs characterized by integration, a sufficient budget for policy implementation, and coercive instruments and sanctions. We then compare survey results to the ways in which Swiss policies have been designed in legislation across policy sectors related to flood risk management over the last 169 years. We find that policy designs follow a national policy style. Placing these results in local contexts, we explain why the design of policies represents both a challenge and opportunity for policy-makers involved in flood risk management.

<p>Flood risk in Italy is a wide-spread and never-ending issue. Traditional flood defense focused on making the river system “resistant” to flood events, possibly by flood-control structures including floodwalls, levees, dams and channels. These actions reduce the frequency of inundations, but they do not affect flooding effects, and associated impacts once the flood plain is inundated. In facts, structural flood defenses are designed and operated to accommodate floods not exceeding a given magnitude, as fixed by the original design. Thus, these engineering works are highly inefficient to cope with capacity-exceeding floods, the magnitude of which was fixed many years ago using poor data sets, and it is expected to increase with climate changes.</p><p>FLORIMAP (Smart FLOod RIsk MAnagement Policies), a project funded by Fondazione CARIPLO aims to revalue extreme floods distribution in the different homogeneous areas of northern Italy using regional approaches based upon recent data form the last three decades.</p><p>FLORIMAP will first cover open issues associated with the quantification of flood hazard and inundation risk, then it will assess human exposure and vulnerability, and combine these issues with strategies of communication and risk management, because risk communication is an important activity that can influence the flood risk management. Communication is the bridge between the technical and professional community, decision makers, elected officials, funding sources, and the public at large. The literature on risk communication and perception has highlighted that the understanding of the psychological perception of environmental risk is a crucial factor in order to foster the community resilience and to promote adaptive attitudes and behaviors.</p><p>Here, we present a preliminary assessment of updated extreme values distribution for the case study of Northern Italy hydrologically homogeneous regions. The results will be then compared against those obtained with previous dataset dating until 1970, to study the evolution of flood hazard and inundation risk under recent climate change. We then provide application of flood hazard, and risk for a case study area, and demonstrate modified hazard under recent climate change.</p><p>We then discuss implications for risk communication in the target areas, and provide suggestions for prosecution of the FLORIMAP project. </p>
