We thus define blue water stress by comparing blue water availability with corresponding net total blue water demand by means of the commonly used, Water Scarcity Index. The results show a drastic increase in the global population living under water-stressed conditions (i.e. moderate to high ...
We then construct a water stress index that integrates the share of runoff being consumed (scarcity), the share of consumption in these inflexible categories (flexibility) and the historical variability of runoff weighted by storage capacity (variability), and use our index to evaluate the trends ...

First, we measured the scarcity risk of each city based on the water stress index (WSI) of the catchment in which the city is located (Table 1). The WSI equals the ratio of water use to water supply and has been widely used to quantify water scarcity (Mekonnen and Hoekstra 2016; Wada...
Soils support a vast amount of carbon (C) that is vulnerable to climatic and anthropogenic global change stressors (for example, drought and human-induced nitrogen deposition). However, the simultaneous effects of an increasing number of global change stressors on soil C storage and persistence ac...
Several methods of aggregating the environmental stressors into an index score are also investigated. A statistical clustering analysis, which we refer to as a "global delta fingerprinting system", across the environmental stresses identifies systems under similar states of threat. Several deltas, ...

In general, the Agricultural Stress Index System (ASIS) proved useful to identify the historical droughts in agriculture at global and continental level. The analysis of the extreme hot spots of agricultural drought does not identify an increase on the number of events and/or in their intensity....
the water stress index (WSI) with the PCRGLOBWB 2 outputs33, environmental flow requirements were not considered. Following Mekonnen and Hoekstra36and Veldkamp et al.37(2017), we used an extreme threshold for WSI of 1.0 (where the entire water available is withdrawn for human use). If a ...
The inadequate availability of clean water presents systemic risks to human health, food production, energy generation and ecosystem functioning. Here we evaluate population exposure to current and future water scarcity (both excluding and including water quality) using a coupled global hydrological and ...
