A global water scarcity assessment for the 21st century was conducted under the latest socio-economic scenario for global change studies, namely Shared Socioeconomic Pathways (SSPs). SSPs depict five global situations with substantially different socio-economic conditions. In the accompanying paper, a water use scenario compatible with the SSPs was developed. This scenario considers not only qu...

This paper presents a global scale assessment of the impact of climate change on water scarcity. Patterns of climate change from 21 Global Climate Models (GCMs) under four SRES scenarios are applied to a global hydrological model to estimate water resources across 1339 watersheds. The Water Crowding Index (WCI) and the Water Stress Index (WSI) are used to calculate exposure to increases and dec...

Climate change and the increasing demand of water intensify global cycle, altering distribution in space time. This is expected to result wet areas getting wetter dry drier. As key life, scarcity likely provoke conflict. Using grid-cell data for Africa central America over years 2002 2017, we provide empirical evidence a link between likelihood local conflict mass declines. We measure anomalies...
