INVENTORY OF TRADITIONAL KNOWLEDGE TO COMBAT DESERTIFICATION

PHOTOGRAPHICAL  AND  TYPOLOGICAL  INVENTORY

C6 - CULTIVATION BY FLOOD RECESSION
The Neolithic ditch of Murgia Timone (Matera). The thicker vegetation makes the ditch visible. On the right the double ring mausoleum of the Bronze Age is evident.
Wadi Saoura (Algeria). The long rocker arms placed on tall adobe uprights, here called khottara and very similar to the ancient Egyptian and Arabian shaduf, enable water to be drawn from the wells dug out of the wadi's sediments.
The Hadramaut valley and the ancient walled town of Shibam surrounded by the embankments and the channels of the traditional system of flood sharing and cultivation of the fields, most of which are now abandoned.
Shibam (Yemen). The ancient dam was not used to create an open-air basin but rather to direct the floods (figure on the right) to the embankments, the channels and the depressions in the gardens.
