Abstract Reducing the social, environmental, and economic impacts of droughts identifying pathways towards drought resilient societies remains a global priority. A common understanding drivers risk ways in which materialize is crucial for improved assessments identification (spatial) planning targeted reduction adaptation options. Over past two decades, we have witnessed an increase across spatial temporal scales drawing on multitude conceptual foundations methodological approaches....
Abstract. Droughts continue to affect ecosystems, communities and entire economies. Agriculture bears much of the impact, in many countries it is most heavily affected sector. Over past decades, efforts have been made assess drought risk at different spatial scales. Here, we present for first time an integrated assessment both irrigated rainfed agricultural systems global scale. Composite hazard indicators were calculated separately using indices based on historical climate conditions...
The regular drought episodes in South Africa highlight the need to reduce risk by both policy and local community actions. Environmental socioeconomic factors Africa's agricultural system have been affected past, creating cascading pressures on nation's agro-economic water supply systems. Therefore, understanding key drivers of all components through a comprehensive assessment must be undertaken order inform proactive management. This paper presents, for first time, national irrigated...
As a result of changes in climatic conditions and greater resistance to insecticides, many regions across the globe, including Colombia, have been facing resurgence vector-borne diseases, dengue fever particular. Timely information on both (1) spatial distribution disease, (2) prevailing vulnerabilities population are needed adequately plan targeted preventive intervention. We propose methodology for assessment current socioeconomic Cali, tropical urban environment Colombia. Based set...
The devastating impacts of drought are fast becoming a global concern. Zimbabwe is among the countries more severely affected, where have led to water shortages, declining yields, and periods food insecurity, accompanied by economic downturns. In particular, country’s agricultural sector, mostly comprised smallholder rainfed systems, at great risk drought. this study, multimethod approach applied, including remote sensing-based analysis vegetation health data from 1989–2019 assess hazard, as...
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...
Despite efforts in eradication and control, malaria remains a global challenge, particularly affecting vulnerable groups. the recession cases, previously free areas are increasingly confronted with epidemics as result of changing environmental socioeconomic conditions. Next to modeling transmission intensities probabilities, integrated spatial methods targeting complex interplay factors that contribute social vulnerability required effectively reduce burden. We propose an integrative method...
Outbreaks of vector-borne diseases (VBDs) impose a heavy burden on vulnerable populations. Despite recent progress in eradication and control, malaria remains the most prevalent VBD. Integrative approaches that take into account environmental, socioeconomic, demographic, biological, cultural, political factors contributing to risk vulnerability are needed effectively reduce burden. Although focus has increasingly gained ground, little emphasis been given develop quantitative methods for...
Abstract Vietnam is exposed to different types of floods that cause severe economic losses, damage infrastructure, and loss life. Reliable information on the drivers, patterns dynamics flood risk crucial for identification, prioritization planning reduction adaptation measures. Here, we present a systematic review existing assessments in Vietnam. We evaluate current status, persisting gaps, challenges regarding understanding assessment country. The literature revealed that: (i) 65 % reviewed...
Abstract Indices assessing country-level climate and disaster risk at the global scale have experienced a steep rise in popularity both science international policy. A number of widely cited products been developed published over recent years, argued to contribute critical knowledge for prioritizing action funding. However, it remains unclear how their results compare, consistent findings are on risk, exposure, vulnerability lack coping, as well adaptive capacity. This paper analyses...
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...
Deprivation indices are widely used to identify areas characterized by above average social and/or material disadvantages. Especially spatial approaches have become increasingly popular since they enable decision makers priority and allocate their resources accordingly. An array of methods reporting units been analyze report deprivation in previous studies. However, a comparative analysis assessment the implications choice unit for quality life health care accessibility planning is still...
Abstract. Drought research addresses one of the major natural hazards that threatens progress toward Sustainable Development Goals. This study aims to map evolution and interdisciplinarity drought over time across regions, offering insights for decision-makers, researchers, funding agencies. By analysing more than 130 000 peer-reviewed articles indexed in SCOPUS from 1901 2022 using latent Dirichlet allocation (LDA) topic modelling, we identified distinct shifts priorities emerging trends....
Communities around the globe are at substantial risk of being threatened by hydrological extremes, particularly floods. Adapting to exacerbating flood risks is hence utmost importance safeguard people’s wellbeing. Households critical for adaptation as their actions have proved effective and efficient in diminishing risks. At same time, past experiences, well capability perceptions often considered important factors driving household adaptation. These linkages suggest complex...
Impact-based early warning (IbEW) is a novel paradigm that aims at improving the efficacy of systems by informing about potential impacts on people, assets and systems, instead only focusing forecasting hazards. While applications are emerging, multiple challenges still remain to develop risk-informed, impact-based warnings useful for triggering actions. Conceptual risk models, such as impact chains or webs, tools increasingly used in assessments inform management adaptation, can provide...
