Aquifers in deserts refill incredibly slowly
Aquifers in arid zones replenish at an incredibly slow pace from scarce rainfall, making them vulnerable to depletion and underscoring global water scarcity challenges.
Underground water reservoirs, called aquifers, recharge agonizingly slowly in arid regions. These parched lands, like deserts, receive minimal rainfall, often less than 250 millimeters annually, and much of that evaporates before it can seep into the ground. This means natural replenishment can take decades, centuries, or even millennia.
