Where ‘day-zero droughts’ could happen as soon as this decade
Many parts of the world are predicted to endure “day-zero droughts,” periods of extreme and unprecedented water scarcity, which could happen as soon as this decade in certain hotspots including parts of North America, the Mediterranean and southern Africa, according to a new study [in Nature Communications]. … Day-zero droughts arise from the confluence of various factors, including a prolonged dearth of rain, low river levels and shrunken reservoirs, as well as rocketing water demand to supply people, farms and industries. … More than a third of these regions, including the western United States, could face this situation as early as the 2020s or 2030s.
