The document discusses monthly blue water scarcity, highlighting that four billion people face severe water scarcity according to research by Mekonnen and Hoekstra (2016). It examines the relationship between blue water footprint and availability, emphasizing that current water usage is not sustainable. Detailed maps and data illustrate the monthly variations in blue water scarcity across different regions.

Editor's Notes
- #2: Citation: Mekonnen, M.M. and Hoekstra, A.Y. (2016) Four billion people facing severe water scarcity, Science Advances, 2(2): e1500323. Strong points: We improve upon past efforts: by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions, and by considering monthly rather than annual values
