During the medieval period, dam- building continued primarily in Asia ante Middle Eass.

By the late 20th century, the global total of large dams disoded 50,000, according te International Commissione on Large Dams. Thi explosion was consun by a belief in centralized, top- down infrastructure as the engine of development. But as environmental science andd affected communities began to organize, the human and ecological costs of damming became impossible ble to ignore.
