The Florescence of Arid Lands in Mesopotamia, Elam, and Central Asia:· An Historical Perspective 1 Jeffrey Zauderer 2 Abstract.--Great civilizations developed arid lands by the extension and management of artificial riverine systems to irrigate cereal cultivars. Areas formerly cultivated are today unproductive, due to the collapse of riverine management. INTRODUCTION winter. The leguminous weed Scorpiurus was spread by Parthian or Sassanian irrigation ( Helbaek 1969). The broad framework for the development of urban societies, and their blossoming into great civilizations Spreading agriculture forced pastoralists to overexploit inarid and semi arid regions, rested upon the physical palatable species. With the appearance of domestic wool systems and social organizations for cultivating cereals sheep, Stipa, a former forage plant for wild sheep, became (lrlams 1969, Wittfogell97l). Wild cereals grew in areas a noxious weed spread by clinging to wool, and shunned receiving 400-500mm rainfall (Raikes 1965), and are because of its habit of burrowing into the sheep's skin cultivated with less than lOOmm.
