Drought impacts monitoring has been called the missing piece in drought assessment. The potential to improve management is high but uncertain due rare analyses of datasets, predominantly because there are few programmes generate datasets. conducted on ground much Brazil by local observers at monthly and municipality scale support Brazilian Monitor. In Ceará state, within drought-prone semiarid northeast Brazil, over 3600 reports were completed agricultural extension officers from 2019 2022. We investigated, through manual coding observer interviews, reported impact drivers. Analysis provided a catalogue experienced showed that still occur, often normalised, during non-drought periods, sometimes as lingering effects previous droughts. drivers non-extreme hydrometeorological conditions or result socio-technical vulnerabilities such insufficient water infrastructure. normalisation "impacts" included, particular: generally accepted level crop losses consistently low reservoir levels around which domestic systems adapted.

Abstract. Drought monitoring and early warning systems (DEWSs) are seen as helpful tools to tackle drought at an stage reduce the possibility of harm or loss. They usually include indices attributed meteorological, agricultural and/or hydrological drought: physically based drivers. These used determine onset, end severity a event. impacts, like water food securities, less monitored even not included in DEWSs. Therefore, likelihood experiencing these impacts is often simply linearly linked drivers drought. The aim this study evaluate validity assumed direct linkage between insecurity We reviewed scientific literature on both conducted bibliometric analysis 5000+ studies which selected (drivers) drought-related insecurities (impacts) were mentioned relation geographic area. Our review shows that there tendency focus drought, with preferred use meteorological remotely sensed indices.

With increasing relevance utility information provided by DEWSs, we argue favour additional consideration impact oriented towards sustainable development welfare.

To increase drought preparedness in semi-arid regions across the world many small and medium reservoirs have been built recent decades. Together these form a Dense Reservoir Network (DRN) its presence generates numerous challenges for water management. Most of that constitute network are unmonitored unregistered, posing questions on their cumulative effects strategic distribution at watershed scale. Their influence hydrological propagation is thus largely unexplored. The objective this study then to assess DRN droughts both time space. A modeling-analytical framework proposed achieve goal. mesoscale semi-distributed model was utilized simulate large large-scale tropical semiarid watershed. investigate space generated by network's presence, differences between multiple scenarios were analyzed.

Abstract Effective drought management must be informed by an understanding of whether and how current monitoring assessment practices represent underlying nonstationary climate conditions, either naturally occurring or forced change. Here we investigate the emerging climatology associated trends in classes defined United States Drought Monitor (USDM), a weekly product that, since 2000, has been used to inform States. The USDM classifies intensity based part on threshold percentiles key hydroclimate quantities. assess those USDM‐defined have changed over last 23 years, examining precipitation, runoff, soil moisture (SM), terrestrial water storage (TWS), vapor pressure deficit (VPD), near‐surface air temperature. We also frequency classifications across U.S. Our analysis suggests that class occurrence is exceeding number regions States, particularly American West, where years emerged as prolonged dry period. These are reflected percentile‐based thresholds SM, TWS, VPD, results emphasize while appears accurately reflecting observed nonstationarity physical climate, such raise critical questions about diagnosis, classification, should address long‐term intervals wet periods trends.

This study applies 'Social-Ecological Systems (SES)' concepts with the aim of analysing why and how events happening across spatial, jurisdictional, temporal scales influence droughts their impacts in rural communities. To trace evolution on livelihood system, we conducted a drought diagnosis community Riacho da Cruz Banabuiú basin semi-arid Northeast Brazil. We analysed this reacted differently to previous either contributed adaptation system or its collapse. SES theory helped us posit that it is collective capacity stakeholders (nested levels different decisional management) manage resilience drought, determines whether considered adapts, collapses shifts into new stable state, response drought. Monitoring these factors could enable development drought(-impact) indices account for spatial-temporal complexities Such results can aid improving targeting policies toward drought-affected communities ensuring they receive necessary resources.

Abstract. Despite recent studies emphasising the dual human and physical nature of droughts, there is a lag in advancing this insight drought monitoring early warning systems (DEWSs). These mainly depend on hydro-climatic indices often overlook experiences affected communities, resulting gap. This study introduces efficacy matrix (MEM) to assess alignment between officially monitored data, relevant impacts, actual rural community northeastern Brazil, which we investigated through interviews. The MEM revealed “drought challenges”, composed mismatches blind spots official data local experiences. Mismatches stem from varying spatial temporal levels; arise diversity resilience strategies, or vulnerabilities, influencing impacts. What define as gap” results tendency prioritise specific pragmatic levels over comprehensive approach. We posit that first step bridging gap can draw inspiration drought-impact-monitoring initiatives, are focused continuous non-extreme events by municipal technical extension officers. However, ultimately remains conditional adaptation DEWS frameworks accommodate integration qualitative representing drought-related context.

Abstract. Human actions induce and modify droughts. Yet, there remain scientific gaps regarding how anthropogenic dynamics hydrological processes are intrinsically entangled in drought evolution. This poses the challenge of developing ways to evaluate human behavior its pattern co-evolution with cycle, mainly related water use landscape modifications. We propose that prospect theory explains emergence impacts, such as crop losses shortage, if they considered failed welfare expectations (“prospects”) due shortage. behavioral economic is dominantly applied explain decision-making under uncertainty. argue it can also contribute explaining socio-hydrological phenomena reservoir effects. new approach bridging natural social sciences perspectives for more integrated management takes into account local context
