Annual water stress for present conditions and projections for two scenarios

Left: present climate; middle: projection for 2050 based on Economy First scenario, median of general circulation models — regional climate models (GCM-RCM) combinations;
right: projection for 2050 based on Sustainability Eventually scenario, median of GCM-RCM combinations.
Yellow: low water stress (withdrawals-to-availability ratio: 0–0.2);
orange: mild water stress (withdrawals-to-availability ratio: 0.2–0.4);
red: severe water stress (withdrawals-to-availability ratio: > 0.4).
