Abstract. WaterGAP is a global hydrological model that quantifies human use of groundwater and surface water as well flows storage thus resources on all land areas the Earth. Since 1996, it has served to assess stress both historically in future, particular under climate change. It improved our understanding continental variations, with focus overexploitation depletion resources. In this paper, we describe most recent version 2.2d, including models, linking computes net abstractions from...
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...
Abstract We quantified groundwater stress worldwide by applying the global water resources and use model WaterGAP 2.2b (Water ‐ Global Assessment Prognosis) for current conditions (1981–2010) as well 2050s under worst‐case greenhouse gas emissions scenario RCP8.5. To improve global‐scale assessments, we suggest three new quantity‐related indicators a way communicating projected future at grid‐cell level (~55 × 55 km) larger spatial units such transboundary aquifers (>20,000 km 2 ). The...
Abstract Electricity production by hydropower is negatively affected drought. To understand and quantify risks of less than normal streamflow for hydroelectricity (HP) at the global scale, we developed an HP model that simulates time series monthly worldwide thus enables analyzing impact drought on HP. The based a new database (GHD), containing 8,716 geo‐localized plant records, values computed hydrological WaterGAP with spatial resolution 0.5°. GHD includes 44 attributes covers 91.8%...

Abstract. Streamflow drought hazard indicators (SDHIs) are mostly lacking in large-scale early warning systems (DEWSs). This paper presents a new systematic approach for selecting and computing SDHIs monitoring human water supply from surface river ecosystems. We recommend considering the habituation of system at risk (e.g., drinking supplier or small-scale farmers specific region) to streamflow regime when indicators; i.e., users DEWSs should determine which type deviation normal certain...

Streamflow drought hazard indicators (SDHI) are mostly lacking in large-scale early warning systems (DEWS). This paper presents a new systematic approach for selecting and computing SDHI monitoring risk human water supply from surface river ecosystems that is also relevant meteorological or soil moisture drought. We rec-ommend considering the habituation of people to streamflow regime (e.g., certain interannual variability relative reduction streamflow) when indicators. Distinguishing four...

<p>Drought is a recurrent global phenomenon considered one of the most complex hazards with manifold impacts on communities, ecosystems, and economies. While many sectors are affected by drought, agriculture’s high dependency water makes it particularly susceptible to droughts, threatening livelihoods many, hampering achievement Sustainable Development Goals. Identifying pathways towards more drought resilient societies analyzing drivers spatial patterns risk...
