Aquifer
An aquifer is an underground layer of rock or sediment that holds water. The Garamantian Empire in the Sahara depended on fossil aquifers tapped by underground channels called foggaras to irrigate its oases, and their depletion is linked to its decline. In Safavid Iran, qanat systems drawing on aquifers likewise supported agriculture.
