This system has relied on earthern and brushwood structures and customary water rules to support subsistence livelihoods of the Wadi Laba communities for many years. This research analyses the effectiveness of the introduction of contemporary water laws and a new headwork which endevour to increase production and standard of living. The lack of success of the new approach, compared with traditional methods of water management are discussed. --- Contents: 1.
