During this Forum the Great Man-Made River International Water Prize for Arid and Semi-Arid Zones, which is awarded every two years, has been given to Bellachheb Chahbani, who has spent more than 25 years at the Institute of Arid Regions in Medenine, Tunisia.
The laureate has helped improve water management and optimize irrigation systems by reducing evaporation and run-off. Scientists and local farmers helped elaborate the technique, which is already in use in central and southern Tunisia as well as in Algeria. In these areas, operating costs have been reduced and crops saved that would otherwise have been killed by drought.
The Tunisian researcher, has invented new techniques to promote the economy of surface water in arid areas. They consist of a float by gravity drainage, a pocket stone buried and drainage pumping in addition to the new method of injecting water retention in small dams.
