“…With respect to the sensitivity analysis (SA), only nine papers (9.5 %) performed it. Most articles applied local SA by comparing the results obtained by changing input methods, such as choosing different weights (Müller et al, 2011;Nazeer and Bork, 2019;Rogelis et al, 2016), aggregation methods (Fernandez et al, 2016;Nazeer and Bork, 2019), or indicators (Rogelis et al, 2016;Zhang and You, 2014). In addition, Abebe et al (2018) quantified sensitivity through variance reduction and mutual information.…”

Abstract. Despite the increasing body of research on flood vulnerability, a review of the methods used in the construction of vulnerability indices is still missing. Here, we address this gap by providing a state-of-art account on flood vulnerability indices, highlighting worldwide trends and future research directions. A total of 95 peer-reviewed articles published between 2002–2019 were systematically analyzed. An exponential rise in research effort is demonstrated, with 80 % of the articles being published since 2015. The majority of these studies (62.1 %) focused on the neighborhood followed by the city scale (14.7 %). Min–max normalization (30.5 %), equal weighting (24.2 %), and linear aggregation (80.0 %) were the most common methods. With regard to the indicators used, a focus was given to socioeconomic aspects (e.g., population density, illiteracy rate, and gender), whilst components associated with the citizen's coping and adaptive capacity were slightly covered. Gaps in current research include a lack of sensitivity and uncertainty analyses (present in only 9.5 % and 3.2 % of papers, respectively), inadequate or inexistent validation of the results (present in 13.7 % of the studies), lack of transparency regarding the rationale for weighting and indicator selection, and use of static approaches, disregarding temporal dynamics. We discuss the challenges associated with these findings for the assessment of flood vulnerability and provide a research agenda for attending to these gaps. Overall, we argue that future research should be more theoretically grounded while, at the same time, considering validation and the dynamic aspects of vulnerability.

“…They are effective in alerting an entire population, day or night (Zunkel, 2015;Mathews et al, 2017;Landry et al, 2019), provided that the distribution of sirens is dense enough to be heard by all. Sirens leave no time for hesitation and require immediate reactions (Reed et al, 2010;Cain et al, 2021;Fekete et al, 2021). But their effectiveness is based on the implicit assumption that the population understands what is expected from them during the alarm (Sorensen, 2000;Linsday, 2011).…”

“…Several studies have raised doubts about the effectiveness of sirens and criticized the heavy investment in this technology in France (Hirel, 2002;Vinet, 2010;Garcia and Fearnley, 2012;Beccerra et al, 2013;Pappenberger et al, 2015;Daupras et al, 2015;Vogel, 2017;Douvinet, 2018;Courteau, 2019). Monthly testing of sirens (e.g., in France, the first Wednesday of each month) has served to remind residents of the existence of sirens (Créton-Cazanave, 2010), but a national study indicated that only 22 % of the popu-lation recognized the sound of alert sirens well enough to guide behavior (Deloitte, 2014).…”

Abstract. In France, sirens have been the principal tool designated to alert the population in the case of danger. However, their efficacity has not been objectively tested. Using a geographical information system, questionnaires, and surveys, we analyzed (1) the spatial distribution of the siren network in relation to the covered population, the hazards threatening different areas, and the actual number of disasters that have occurred in the past, (2) the political dilemma of activating sirens, and (3) the population's trust in sirens, as well as its understanding of expected behavior in the case of an emergency. Results show that, with a few exceptions, siren coverage in France is primarily determined by population density, not by the expected hazards or the cumulative number of past disasters. Sirens are also rarely used by the authorities. However, surveyed members of the population identify sirens as the most effective alert system over other alternatives such as cell-phone-based alerting tools. In a “mock” emergency most members of the public did not know how to respond in the case of an emergency, and even most of those who correctly identified the appropriate response prior to the exercise did not react upon later hearing the siren. To improve the effectiveness of the French siren network, we recommend (1) relocating sirens to optimize their efficiency, (2) complementing the sound of sirens with a clear and unified message, (3) reorganizing the competencies to activate siren alerts, and finally (4) improving public education on different alert tools and expected behavior during an emergency.

“…Identifying, mapping and analyzing landowner and stakeholder interests and their potential for commitments are key steps in such processes (Blazquez et al., 2021). However, it is even more important to ensure that the engagement is inclusive, transparent, and persistent over time (Fekete et al., 2021; Zilans et al., 2019).…”

Land Policy for Flood Risk Management—Toward a New Working Paradigm

et al. 2022

View full text Add to dashboard Cite

Flood risk management (FRM) aims to integrate necessary technical measures with environmental and societal approaches. Focusing on the process and governance of how to plan, implement, and maintain solutions therefore becomes essential. Among the different stakeholders, landowners are a key group to be considered. This contribution elaborates on the interconnections between land policy, FRM and private land ownership. It is based on the European COST Action network LAND4FLOOD, which brings together academics and stakeholders from various disciplines and more than 35 countries. We argue for a less project oriented and more process oriented approach, a focus on land management and more emphasis on small‐scale measures. This represents a break with some of the recent working paradigms of FRM.
