Houses in early agricultural settlements included special storage areas. They were centered on clay or stone hearths that were ventilated by a hole in the roof. To defend their cities from the rival nomadic settlements, they fortified their cities. The people had devised ways of storing rain water and rechanneling river water to irrigate plants. The reservoirs and canals, dikes and sluices that permitted water storage were constructed.
