Abstract. This paper provides a review of multi-criteria decision-making (MCDM) applications to flood risk management, seeking highlight trends and identify research gaps. A total 128 peer-reviewed papers published from 1995 June 2015 were systematically analysed. Results showed that the number MCDM publications has exponentially grown during this period, with over 82 % all since 2009. wide range identified, most focusing on ranking alternatives for mitigation, followed by risk, hazard,...
Abstract Storms include a range of weather events resulting in heavy liquid and solid precipitation high winds. These critically impact crops natural resources and, turn, health, economy, infrastructure safety. The intensity frequency the physical mechanisms triggering storms will most likely increase under global warming due to changing flows water energy atmosphere. Addressing storm threats holistically requires nexus approach that links climate change, infrastructure, human prosperity...

Contemporary drought impact assessments have been constrained due to data availability, leading an incomplete representation of trends. To address this, we present a novel method for the comprehensive and near-real-time monitoring socio-economic impacts based on media reports. We tested its application using case exceptional 2018/19 German drought. By employing text mining techniques, 4839 statements were identified, relating livestock, agriculture, forestry, fires, recreation, energy...
The understanding of compounding and cascading impacts is becoming increasingly central to the risk reduction debate as hazard consequences are strongly coupled. Still, studies on their quantification visualization limited. This restricts establishment impact-based early warning systems. Here, a novel method for quantifying drought compound paths presented by integrating network analysis data mining tools. 2018/19 in Germany used case study. Network graphs employed display impact...
Index-based approaches are widely employed for measuring flood vulnerability. Nevertheless, the uncertainties in index construction rarely considered. Here, we conducted a sensitivity analysis of vulnerability Maquiné Basin, Southern Brazil, considering distinct normalization, aggregation, classification methods, and their effects on model outputs. The robustness results was investigated by Spearman’s correlations, shift rank, spatial different normalization techniques (min-max, z-scores,...
This data paper describes the multinational Database of Flood Fatalities from Euro-Mediterranean region FFEM-DB that hosts 2,875 flood fatalities 12 territories (nine which represent entire countries) in Europe and broader Mediterranean 1980 to 2020. The database provides on fatalities' profiles, location, contributing circumstances, allowing researchers risk managers explore demographic, behavioral, situational factors, as well environmental features flood-related mortality. standardized...
Droughts are expected to increase both in terms of frequency and magnitude across Europe. Despite the multitude adverse effects these disasters impose on social-ecological systems, most impact assessments constrained single event and/or sector analyses. Furthermore, existing longitudinal multi-sectoral datasets limited spatiotemporal homogeneity scope, resulting fragmented datasets. To address this gap, we propose a novel method for automatized detection drought impacts based newspaper...
Abstract Hydrological extremes, such as droughts and floods, can trigger a complex web of compound cascading impacts (CCI) due to interdependencies between coupled natural social systems. However, current decision‐making processes typically only consider one impact disaster event at time, ignoring causal chains, feedback loops, conditional dependencies impacts. Analyses capturing these patterns across space time are thus needed inform effective adaptation planning. This perspective paper...
The new scientific decade (2023-2032) of the International Association Hydrological Sciences (IAHS) aims at searching for sustainable solutions to undesired water conditions - may it be too little, much or polluted. Many current issues originate from global change, while problems must embrace local understanding and context. will explore crises by actionable knowledge within three themes: interactions, innovative cross-cutting methods. We capitalise on previous IAHS Scientific Decades...
This study presents a methodology for conducting sensitivity and uncertainty analysis of GIS-based multi-criteria model used to assess flood vulnerability in case Brazil. The paper explores the robustness outcomes against slight changes criteria weights. One criterion was varied at-a-time, while others were fixed their baseline values. An algorithm developed using Python geospatial data abstraction library automate variation weights, implement ANP (analytic network process) tool, reclassify...
Abstract This article evaluates the current gaps and describes opportunities for improving flood risk management (FRM) in Ghana, West Africa. A mixed‐method participatory approach comprising questionnaires, workshops, interviews with key stakeholders, a systematic literature review were employed. Existing problems, discourses, FRM practices, to enhance resilience identified. They provided basis outlining potential research directions into ways of tracking these challenges. The results show...
Participation is an often-demanded process in disaster risk reduction (DRR). However, it often unclear who understands what under this term. International organizations such as the United Nations have promoted participation their DRR strategies since 1980s, but further research needed on its opportunities and limitations. Here we highlight understood by according to different actors various international contexts. This study was motivated a workshop where flood-risk resilience experts from...

The increasing use of text as data in environmental research offers valuable opportunities, but the inherent biases within textual sources like news, social media, or disaster reports necessitate moving beyond purely descriptive analyses. While NLP techniques topic modeling and categorical annotations can identify emergent patterns, they often fail to elucidate underlying causal mechanisms driving observed phenomena, especially complex interplay anthropogenic activities, societal structures,...
Abstract. Given the recent developments in socio-hydrology and its potential contributions to disaster risk reduction (DRR), we conducted a systematic literature review of socio-hydrological studies aiming identify persisting gaps discuss tractable approaches for tackling them. A total 44 articles that address natural hazards or disasters were reviewed detail. Our results indicated that: (i) most addressed floods, whereas few applications applied droughts compound multi-hazard events; (ii)...
Abstract. Droughts often lead to cross-sectoral and interconnected socio-economic impacts, affecting human well-being, ecosystems, economic development. Extended drought periods, such as the 2018–2022 event in Germany, amplify these impacts due temporal carry-over effects. Yet, our understanding of impact dynamics during increasingly frequent multi-year periods is still its infancy. In this study, we analyse Germany compare them previous single-year events. Leveraging text-mining tools,...
Abstract Soil is central to the complex interplay among biodiversity, climate, and society. This paper examines interconnectedness of soil climate change, societal impacts, emphasizing urgent need for integrated solutions. Human‐induced biodiversity loss change intensify environmental degradation, threatening human well‐being. Soils, rich in vital ecosystem function regulation, are highly vulnerable these pressures, affecting nutrient cycling, fertility, resilience. also crucially regulates...
Abstract Agriculture contributes in several ways to achieving sustainability objectives. However, there is no agreement among different societal groups, such as farmers, consumers and scientists, on what constitutes ‘sustainable agriculture’. These differences affect how the impacts of agricultural production objectives perceived, which solutions are considered implemented. In this paper, we investigate topics discussed under heading agriculture’ German newspapers magazines. To end, apply...
Abstract. Dynamic vulnerability, driven by changing social, economic, physical, and environmental characteristics, is critical to understanding flood risk. Despite its importance, existing risk assessment research often overlooks the mechanisms that drive dynamic vulnerability interactions between underlying characteristics. In this study, we systematically review methods used assess in context of floods compile their findings about drivers effects dynamics a dataset. We identify 28 relevant...
Extreme climate events like storms, heatwaves, wildfires, floods, and droughts pose serious threats to human society ecosystems. Measuring their impacts remains a crucial challenge scientifically. Although data linking hazards socio-economic effects are crucial, public availability is still relatively sparse. Existing open databases such as the Emergency Events Database (EM-DAT) DesInventar Sendai offer some impact on extremes,  but extremes also appear in newspapers, reports,...
