  abstract = {{T}imimoun is located in the hyper-arid zone of the {S}ahara, with an annual rainfall not exceeding 100 mm/year. {T}o fill the shortage of rainfall, the oasis has developed a traditional means for mobilization of the groundwater. {I}n the foggara with this hydraulic system, oases have been developed throughout the region of {T}imimoun over ten centuries. {T}oday, we witness the gradual disappearance of foggaras; we lose about one to two foggaras per year for over half a century. {T}he discharge of the 250 functional foggaras shows a significant drop: 850 l/s in 1960 and 355 l/s in 2001, enough to irrigate 350 ha. {T}he causes of declining foggaras are technical, social, and environmental. {T}he surveys that we have led nearly with the population in the ksour during two missions in 2007 and 2008 in the oasis of {T}imimoun reveal that socio-economic problems ({H}eritage and depopulation) are common to both types of foggara (foggara of the {E}rg and foggara {A}lbian). {E}nvironmental problems (silting and flooding of the galleries by wild plants) are the main causes of the disappearance of foggaras of {E}rg. {T}echnical problems (collapse of tunnels) are mainly the causes of degradation to {A}lbian's foggaras. {A}ttempts to introduce changes to foggaras are temporary solutions. {T}he modern collection of water (pump and drilling) is gradually replacing the traditional hydraulic system.},
