In the context of emergency management, individual or household decisions to engage in risk mitigation behaviors are widely recognized to be influenced by a benefit–cost perception (perceived applied value (PAV) vs. perceived economic value (PEV), respectively). To better understand how such decisions are made, we conducted a mail survey (N = 211) of households living in the Red River of the North Basin, North Dakota, in 2018. The survey is aimed at understanding the overall experience of households with flooding and their behavior toward advanced protective strategies against future floods by analyzing household PEV—their willingness to pay for the National Aeronautics and Space Administration’s (NASA) Satellite Enhanced Snowmelt Flood Prediction system. This paper presents a mediation model in which various predictors (flood risk, experience, flood knowledge, flood risk perception, flood preparedness, flood mitigation, and flood insurance) are analyzed in relation to the PAV of the new Satellite Enhanced Snowmelt Flood Predictions in the Red River of the North Basin, which, in turn, may shape the PEV of this product. We discuss the potential implications for both the emergency management research community and professionals regarding the application of advanced risk mitigation technologies to help protect and sustain communities across the country from floods and other natural disasters. This paper provides a greater understanding of the economic and social aspects of sustainability in the context of emergency management and community development. Full article

Urban pluvial flooding (UPF) is an increasingly critical issue due to rapid urbanization and intensified precipitation driven by climate change that yet remains understudied in the Caribbean. This study analyzes the effects of UPF resulting from the transformation of a natural karstic landscape into an urbanized area considering a sub-watershed in Chetumal, Southern Mexican Caribbean, as a case study. Hydrographic numerical modeling was conducted using the IBER 2.5.1 software and the SCS-CN method to estimate surface runoff for a critical UPF event across three stages: (i) 1928—natural condition; (ii) 1998—semi-urbanized (78% coverage); and (iii) 2015—urbanized (88% coverage). Urbanization led to the orthogonalization of the drainage network, an increase in the sub-watershed area (20%) and mainstream length (33%), flow velocities rising 10–100 times, a 52% reduction in surface roughness, and a 32% decrease in the potential maximum soil retention before runoff occurs. In urbanized scenarios, 53.5% of flooded areas exceeded 0.5 m in depth, compared to 16.8% in non-urbanized conditions. Community-based knowledge supported flood extent estimates with 44.5% of respondents reporting floodwater levels exceeding 0.50 m, primarily in streets. Only 43.1% recalled past flood levels, indicating a loss of societal memory, although risk perception remained high among directly affected residents. The reported UPF effects perceived in the area mainly related to housing damage (30.2%), mobility disruption (25.5%), or health issues (12.9%). Although UPF events are frequent, insufficient drainage infrastructure, altered runoff patterns, and limited access to public shelters and communication increased vulnerability. Full article

Coastal cities and low-lying areas are increasingly vulnerable, and accurate data is needed to identify where interventions are most required. We compared 53 cities affected by a 1 m increase in land levels and a 2 m rise in sea levels. The geographical scope of this study covered selected coastal cities in Europe and northern Africa. Data were sourced from the European Environment Agency (EEA) in the form of prepared datasets, which were further processed for analysis. Statistical methods were applied to compare the extent of urban flooding under two sea level rise scenarios—1 m and 2 m—by calculating the percentage of affected urban areas. To assess social vulnerability, the analysis included several variables: MAPF65 (Mean Area Potentially Flooded for people aged 65 and older, indicating elderly exposure), Age (the percentage of the population aged 65+ in each city), MAPF (Mean Area Potentially Flooded, representing the average share of urban area at risk of flooding), and Unemployment Ratio (the percentage of unemployed individuals living in the areas potentially affected by sea level rise). We utilized t-tests to analyze the means of two datasets, yielding a mean difference of 2.9536. Both parametric and bootstrap confidence intervals included zero, and the p-values from the t-tests (0.289 and 0.289) indicated no statistically significant difference between the means. The Bayes factor (0.178) provided substantial evidence supporting equal means, while Cohen’s D (0.099) indicated a very small effect size. Ceuta’s flooding value (502.8) was identified as a significant outlier (p < 0.05), indicating high flood risk. A Grubbs’ test confirmed Ceuta as a significant outlier. A Wilcoxon test highlighted significant deviations between the medians, with a p << 0.001, demonstrating systematic discrepancies tied to flood frequency and sea level anomalies. These findings illuminated critical disparities in flooding trends across specific locations, offering essential insights for urban planning and mitigation strategies in cities vulnerable to rising sea levels and extreme weather patterns. Information on coastal flooding provides awareness of how rising sea levels affect at-risk areas. Examining factors such as MAPF and population data enables the detection of the most threatened zones and supports targeted action. These perceptions are essential for strengthening climate resilience, improving emergency planning, and directing resources where they are needed most. Full article

The increasing frequency and intensity of extreme environmental phenomena mandate further actions to protect the most vulnerable groups, especially children. Traditionally, children have been excluded from conversations about disasters; however, this exclusion is reductive and perpetuates false ideas about children’s capacity to engage with safety information and materially manifest sustainable practices in their life. Such a reality is also impractical because early exposure through learning opportunities can yield engagement in sustainable development in adulthood. This research sought to improve understanding about children’s capacity to engage in DRR information. This study reviewed posters created by 7-year-old children at a primary school in the UK. These were produced as part of prior climate change workshops and included an illustration of a flood safety kit with items children would choose to have with them if there was an emergency (e.g., flooding event). Items included were counted and tallied to identify trends. The results demonstrated the capacity of children in this age group to select practically useful items for their safety in flooding emergencies. Based on findings, this study advocates for greater inclusion of children within disaster preparedness activities and the production of more tailored DRR learning opportunities to engage children within their school environment.

In recent decades, the intensification of extreme events, such as floods, earthquakes, and hydrogeological instability, together with the spread of pollutants harmful to health, has highlighted the vulnerability of territories and the need to direct urban policies towards sustainable strategies. The built assets and the real estate sector play a key role in this context; indeed, being among the first ones to be exposed to the effects of climate change, they serve as a crucial tool for the implementation of governance strategies that are more focused on environmental issues. However, the insufficient allocation of public resources to interventions to secure the territory has made it essential to involve private capital interested in combining the legitimate needs of performance with the “ethicality” of the investment. In light of the outlined framework, real estate managers are called upon to take into consideration the environmental risks associated with real estate investments and accurately represent them to investors, especially in the fundraising phase. The tools currently used for the analysis of such risks are based on their perception measured by the “risk premium” criterion, reconstructed on the basis of previous trends and the analyst’s expertise. The poor ability to justify the nature of the risk premium and the uncertainty about future scenario evolutions make this approach increasingly less valid. The present work, starting from the aspects of randomness of the risk premium criterion, aims at its evolution through the inclusion of environmental risk components (seismic, hydrogeological, and pollution).

This research addresses the increasing vulnerability of coastal urban areas to climate change, with a particular focus on the increased risk of overtopping and coastal flooding events in Praia da Vitória, Azores. This study, conducted within the LIFE-GARACHICO project, aims to develop a holistic and flexible management approach to coastal flood risk. The methodology included a comprehensive risk assessment that combined a vulnerability analysis (considering factors such as population, land use, and infrastructure) with the probability of coastal inundation events (using oceanographic data and models). Public risk perception was assessed through surveys to understand residents’ awareness and preferences. A response protocol for overtopping events was developed with civil protection officials, and the HIDRALERTA early warning system was implemented. The risk assessment showed a mostly acceptable risk with some undesirable areas, resulting from a mostly low probability and medium vulnerability. Public surveys indicated that residents had experienced flooding but felt unprepared and preferred softer management measures such as access restrictions and early warning systems. The response protocol developed and integrated into HIDRALERTA responds to these preferences. This study concludes that this integrated framework improves coastal risk management, increases public awareness and confidence, and provides a flexible and sustainable model for coastal risk management.

This research focuses on current photojournalism practices in the media representation of the climate crisis, exploring how images published by Spain’s leading digital newspapers contribute to shaping public perception of the phenomenon. Through a mixed-methods approach, this study examines eco-visual reporting in 2023—a year characterized by unprecedented global temperatures—alongside an examination of the initial month of coverage of the 2024 DANA floods. The main objective of this study is to evaluate whether the visual depiction of climate change in mainstream media aligns with or deviates from the established visual patterns associated with stereotyped iconography and alarmist narratives. This research provides a taxonomy of the predominant thematic elements and their frequency, addressing key issues such as the persistence of worn-out visual tropes, the reliance on stock images, and the episodic nature of its news treatment. The inclusion of the most catastrophic climate disaster of the 21st century in Spain allows for an exploration of how the media pressure inherent to crisis situations intensifies the risk of errors in image attribution and contextualization. Finally, we offer practical recommendations to guide visual coverage toward comprehensive, accurate, and human-centered approaches, aiming to foster public trust and maximize the potential of photojournalism as a key tool in collective mobilization against the climate emergency.

Flooding is a prevalent and growing problem involving significant economic losses worldwide. Traditional flood mitigation measures are based on the use of levees, dams, dredging, and river channelization, which can distort the perception of risk, leading to a false sense of security that can induce an increase in the occupation of flood-prone areas. An undisturbed watershed and its fluvial system provide regulating services that contribute to flood mitigation. However, anthropogenic activities can degrade and diminish such services, impacting the magnitude of floods by changing the runoff patterns, erosion, sedimentation, channel conveyance capacity, and floodplain connectivity. Restoration and natural flood management (NFM) seek to recover and improve their watershed regulation services. The bibliographic review performed here aimed to assess the degradation of the natural regulation services of watersheds, which allowed us to identify significant alterations to runoff and streamflow. Also, the review studies of NMF allowed us to identify the restoration actions oriented to recover or enhance the flow regulation capacity of catchments and their fluvial systems. A current challenge is to accumulate more empirical evidence for the effectiveness of such flood mitigation solutions. Currently, the results for large catchments have been obtained mainly by the application of hydrologic and hydraulic models. Also, the adequacy of the different NFM actions to catchments with different physiographic and climatological settings needs to be addressed. Full article

This study examines the factors influencing home elevation decisions among participants in Houston’s Homeowner Assistance Program (HoAP) and the Texas General Land Office’s Homeowner Assistance Program (HAP) in the aftermath of Hurricane Harvey and other flood events. Using a mixed-methods approach, we conducted surveys and semi-structured interviews with 50 homeowners, supplemented by secondary data analyses of program records and GIS-based flood risk assessments. Additionally, 25 undergraduate students engaged in a structured field trip, conducting site observations, interacting with residents, and discussing home elevation with experts. The findings reveal disparities in home elevation outcomes, with lower completion rates in socially vulnerable neighborhoods despite program eligibility. The study also identifies key factors influencing elevation decisions, including mobility concerns, financial constraints, neighborhood esthetics, and perceptions of long-term flood risk. Homeowners aged 60–79 were more likely to elevate their homes, while individuals with disabilities faced additional barriers. This research highlights the need for targeted policy interventions to improve program equity and ensure that vulnerable populations receive adequate support. Beyond its case study implications, this research contributes to broader discussions on disaster recovery, climate adaptation, and urban resilience. It also serves as a model for integrating student learning into community-based participatory research. While this study is limited in scope, it offers insights into the intersection of social vulnerability and housing adaptation, informing future policy efforts to enhance flood resilience in historically marginalized communities.

The present study examines perceptions and preparedness for flooding in Greece, a country increasingly impacted by natural hazards, particularly due to the effects of climate change. Despite the frequent occurrence of floods, public preparedness remains insufficient in many areas. Through a survey of 1282 respondents from various regions of Greece and using R statistical software to process and analyse data, the research explores the relationship between individual flood risk perceptions, prior experiences, and household-level preparedness. The findings show most participants are aware of governmental flood plans, but a significant gap exists between perceived flood risks and actual preparedness, especially regarding insurance and relocation willingness. The findings reveal that a majority of participants are aware of governmental flood management plans; however, outcomes concerning flood insurance and the willingness to relocate highlight the significant gap between perceived flood risks and actual preparedness efforts. Many respondents expressed dissatisfaction with current measures to address flood risks, leading to a diminished trust in the respective authorities. To enhance public awareness and engagement in flood preparedness, the study underscores the importance of localized risk communication strategies tailored to different demographic groups. Given the observed gap between awareness and actual preparedness, efforts should focus on bridging this disconnect through practical, community-driven initiatives. Recommendations include implementing targeted awareness campaigns, promoting trust in government efforts through transparent policies, and providing financial incentives such as subsidized flood insurance to encourage protective actions, and, additionally, fostering community involvement in disaster risk management, particularly in historically flood-prone regions, to strengthen the resilience against future flooding events.

Climate change, a critical global challenge, is evident in rising global temperatures, shifting precipitation trends, and extreme weather events, including floods, heatwaves, and rising sea levels. The impacts of climate change not only endanger physical health but also affect mental well-being, particularly among populations experiencing frequent or severe climate-related events. Understanding individual perceptions of climate risks and adaptive capacities is crucial for developing strategies that promote health resilience and environmental protection. This paper examines how risk perceptions, direct experiences with extreme weather, and perceived adaptive capacities influence climate change protection measures and support for relevant policies. Data were gathered from 291 respondents in the United Arab Emirates using structured questionnaires. The data were analyzed using descriptive statistics, reliability analysis, Cronbach’s alpha, Spearman correlation analysis, and multiple regression analysis to determine key predictors of policy support. The results indicate that age is positively correlated with policy support (ρ = 0.16, p = 0.001), while gender also plays a role, with women showing greater risk perception and stronger policy support than men. In contrast, formal education and employment status do not significantly impact policy endorsement or climate adaptation behaviors. These findings suggest that awareness-based interventions alone may be insufficient to drive climate action. Instead, policies should leverage older individuals’ experiences, enhance workplace and community-based climate engagement, and prioritize hands-on, action-oriented education to bridge the gap between climate knowledge and adaptive behavior.

Floods are the natural hazards that cause the most damage and affect the most people in Spain. However, the response of the population and the actions they take before, during and after the emergency can be inappropriate due to inaccurate risk perception and preparation. This paper presents an analysis of the floods of 22–23 October 2019 in the upper area of the Francolí watershed (Catalonia, NE Spain), with the aim of analysing how to improve public perception and impact estimation through citizen science. To this end, a campaign (FLOODUP-Francolí) was organised together with a local institution that helped to engage participants. This consisted of a kick-off conference, a period of participation through tools adapted to the virtual format, including a questionnaire, and a face-to-face conference to present the results. The detailed analysis of the actions taken in the emergency allowed the identification of key aspects to improve flood prevention, response and recovery processes: clarity and consistency of communication, channels of communication, the timing of warnings, the preparedness of the population and the existence of agreed-upon self-protection protocols. Finally, this study demonstrates the contribution of citizen science initiatives in the field of natural hazards to improving community resilience and historical memory. Full article

Agriculture, livestock, and forestry are crucial in mitigating hydrogeological risks, such as floods, particularly severe in the Mediterranean region. Still, the ecosystem services (ESs) provided by these activities are often undervalued. However, to assign them an economic value and ensure their effective incorporation into decision-making processes and territorial planning, they must first be recognized, appreciated, and deemed necessary by society. Despite several studies on ESs in the primary sector, research on agroecosystem flood regulation is limited, leaving key aspects unaddressed for decision-makers. No previous studies explicitly address the evaluation of ESs provided by agriculture, livestock, and forestry businesses in hydrogeological risky environments, especially in flood-prone areas. This study investigates the perception of the ESs provided by the above activities, focusing on those furnished in areas subject to hydrogeological instability. It also focuses on Sardinia (Italy), which is highly susceptible to hydrogeological instability. Through a quantitative survey of 270 residents and non-residents, the research provides evidence of society’s perception of the above ESs. Supporting ESs obtain greater appreciation in crop activities, particularly concerning the preservation of pollinating insects, soil fertility, biodiversity, and water quality. Among the regulatory Ess, appreciation is most prominent in fire risk management and flood risk regulation. Similar arguments can be made for livestock activities. Forestry activities are perceived as key players in managing flood risk, landslide risk, soil erosion, and climate change. The Multiple Correspondence Analysis indicates that appreciating one ES often leads to the recognition of others. Additionally, a set of Logit Regressions showed that while age and gender do not influence ESs perception, education level and awareness of climate change-related emergencies play a significant role. Those findings support more informed decision-making and fostering sustainable practices in areas at risk of hydrogeological disasters and lead to several important implications for practitioners, academics, and policymakers.

This study presents the results of a survey on flood risk awareness conducted in the Italian Alps, examining the impacts of a major weather event on public perception and trust. It develops a systems-thinking framework to analyse dynamic feedback loops influencing flood risk management support over time. The survey data collection overlapped with a severe storm event in Central Europe, the storm “Adrian” (also known as “Vaia”). This provided a unique pre- and post-event perspective. Results highlight the critical role of individual knowledge, trust in authorities, and social group dynamics in shaping risk perception processes. The study shows how major weather events can change perceptions, sense of safety, and institutional trust within local communities, and more interestingly, these changes can vary spatially. The findings are summarised using a systems-thinking framework, which helps to identify possible feedback loops between flood risk management interventions and long-term public support. The study emphasizes the importance of forward-looking, systems-thinking approaches in the design, monitoring, and evaluation of flood risk management plans. These approaches allow one to account for often-overlooked dynamics, such as spatially varying feedback loops and counter-intuitive effects, ultimately improving the long-term effectiveness of flood risk management.

Urban flooding is a widespread and impactful natural hazard, presenting considerable challenges to urban areas. Integrating peri-urban forests (PUFs) into flood management strategies has emerged as a promising approach to mitigate flood hazards. Citizen engagement in PUF management can enhance flood risk reduction efforts. A notable research gap exists in understanding the factors influencing citizens’ intentions to participate in PUF management for flood mitigation. To address this gap, this study investigates the determinants shaping citizens’ intention to engage in PUF management efforts. Using an extended Theory of Planned Behavior framework—which incorporates environmental awareness and risk perception—this research surveyed visitors to PUFs in Tehran. Structural equation modeling with SmartPLS was applied to examine the relationships among these variables. The findings reveal that attitudes, subjective norms, perceived behavioral control, and environmental awareness significantly influence citizens’ intentions. In contrast, perceived risk had no significant effect. This study highlights the importance of fostering positive attitudes toward PUF management, creating a supportive social environment, empowering individuals with knowledge and resources, and emphasizing environmental awareness in flood hazard reduction. The results provide empirical evidence supporting the inclusion of environmental awareness as a key determinant in an extended behavioral model. Enhancing citizens’ understanding of the immediate benefits of PUFs is crucial for promoting active participation in flood mitigation initiatives. Full article
