Between 1960 and 2010, global groundwater extraction increased by more than 50 per cent, largely to irrigate crops. Today, one-fifth of all food is produced using groundwater. Much of this water is extracted from aquifers faster than they naturally refill, driving declining water levels. This causes the land to sink,…
