Figure 8.6 shows how groundwater levels on March 15, 2021, compared to long-term records for the month of March. Blue areas had more abundant water than usual, and orange and red areas had less. The darkest reds represent dry conditions that should occur only two percent of the time (about once every 50 years). Northern India and parts of Pakistan have conditions that should occur only two percent of the time. There are efforts underway to use data like this to better manage water resources in the region.
