Abstract. Drought is a natural hazard that can cause wide range of impacts affecting the environment, society, and economy. Providing an impact assessment reducing vulnerability to these for regions beyond local scale, spanning political sectoral boundaries, requires systematic detailed data regarding impacts. This study presents diversity drought across Europe based on European Impact report Inventory (EDII), unique research database has collected close 5000 reports from 33 countries. The...
Abstract. Since 1990, natural hazards have led to over 1.6 million fatalities globally, and economic losses are estimated at an average of around USD 260–310 billion per year. The scientific policy communities recognise the need reduce these risks. As a result, last decade has seen rapid development global models for assessing risk from scale. In this paper, we review literature on hazard assessments scale, specifically examine whether how they examined future projections hazard, exposure,...
It is generally accepted that drought one of the most costly weather-related natural hazards. In 2015, a long-lasting hit Europe, particularly affecting central and eastern Europe. some regions it was driest (North Slovakia) in others (Czech Republic Poland) second summer last 50 years (following 2003). Key questions are: (i) how extreme are these events, not only terms hydro-meteorological characteristics but also impacts? (ii) impacts managed? Droughts often viewed from climatic...
Abstract. Drought is one of the most costly natural hazards in Europe. Due to its complexity, drought risk, meant as combination hazard and societal vulnerability, difficult define challenging detect predict, impacts are very diverse, covering breadth socioeconomic environmental systems. Pan-European maps risk could inform elaboration guidelines policies address documented severity impact across borders. This work tests capability commonly applied indices vulnerability factors predict annual...
Drought in Europe is a hazard with wide range of transboundary, environmental and socio-economic impacts on various sectors including agriculture, energy production, public water supply quality. Despite the apparent importance this natural hazard, observed pan-European drought have not yet been quantitatively related to most important climatological drivers map risk continental scale. This contribution approaches issue by assessing likelihood impact occurrence as function standardized...
For the development of sustainable, efficient risk management strategies for hydrological extremes droughts and floods, it is essential to understand temporal changes impacts, their respective causes interactions. In particular, little known about in vulnerability influence on drought flood impacts. We present a fictitious dialogue between two experts, one other showing that main obstacles scientific advancement this area are both lack data commonly accepted approaches. The experts "discuss"...
Present-day drought early warning systems provide the end-users information on ongoing and forecasted hazard (e.g. river flow deficit). However, impacts, which is a prerequisite for management, still missing. Here we present first study assessing feasibility of forecasting using machine-learning to relate hydro-meteorological indices reported impacts. Results show that models, were built with more than 50 months are able forecast impacts few ahead. This highlights importance impact databases...
Abstract. Drought events and their impacts vary spatially temporally due to diverse pedo-climatic hydrologic conditions, as well variations in exposure vulnerability, such demographics response actions. While hazard severity frequency of past drought have been studied detail, little is known about the effect management strategies on actual how perceived by relevant stakeholders. In a continental study, we characterised assessed perceptions two recent (2018 2019) Europe examined relationship...
Abstract. Droughts often have a severe impact on the environment, society, and economy. The variables scales that are relevant to understand of drought motivated this study, which compared hazard propagation characteristics, as well impacts, major droughts between 1990 2019 in southwestern Germany. We bring together high-resolution datasets air temperature, precipitation, soil moisture simulations, streamflow groundwater level observations, text-based information impacts. Various...
Abstract In the last few years, world has experienced numerous extreme droughts with adverse direct, cascading, and systemic impacts. Despite more frequent severe events, drought risk assessment is still incipient compared to that of other meteorological climate hazards. This mainly due complexity drought, high level uncertainties in its analysis, lack community agreement on a common framework tackle problem. Here, we outline effectively assess manage risks, perspective needed. We propose...
Drought directly and indirectly affects the entire socio-economic environmental sectors in southwestern Germany. Such impacts are a result of drought hazard an underlying vulnerability systems. With respect to climate change dynamics over time, it becomes crucial investigate preceding components, order understand possible future magnitudes drivers impacts. Therefore, indices were generated from early nineteenth century identify exceptional meteorological summer droughts. Documentary evidence...
During the last 20 years, Argentina experienced several extreme and widespread droughts in many different regions, including core cropland areas. The most devastating recent events were recorded years 2006, 2009 2011. Reported impacts of main induced losses more than 4 billion U.S. dollars 1 million persons reported to be directly or indirectly affected. In this paper, we analyse drought risk Argentina, taking into account information on hazard, exposure vulnerability. Accordingly,...
Abstract. Droughts are multidimensional hazards that can lead to substantial environmental and societal impacts. To understand causes impacts, multiple perspectives need be considered. Many studies have identified past drought events investigated propagation from meteorological droughts via soil moisture hydrological droughts, some included the impacts of these different types drought. However, it is not certain whether increased frequency severity in decade unprecedented recent history....
Abstract A limited number of gauging stations, especially for nested catchments, hampers a process understanding the interaction between streamflow, groundwater and water usage during drought. Non‐commercial measurement devices can help overcome this lack monitoring, but they need to be thoroughly tested. The Dreisam River in South‐West Germany was affected by several hydrological drought events from 2015 2020 which parts main stream tributaries fell dry. Therefore it provided useful case...

Abstract. Forecasting of drought impacts is still lacking in early-warning systems (DEWSs), which presently do not go beyond hazard forecasting. Therefore, we developed impact functions using machine learning approaches (logistic regression and random forest) to predict with lead times up 7 months ahead. The observed forecasted hydrometeorological hazards – such as the standardized precipitation index (SPI), evaporation (SPEI), runoff (SRI) were obtained from EU-funded Enhancing Emergency...

In recent years, research on drought risk has expanded to include multiple types of hazards, various exposed elements and a multitude factors that determine the vulnerability given system or sector. This resulted in call from scientific community adopt systemic perspective drought. However, thorough understanding how risks manifest, cascade interact across different systems sectors is still lacking, methodological guidance analyse represent these interdependencies does not yet...
