{summary}There is a long history of olive tree growing in hilly regions of Tunisia. It is one of the few arboreal species that enhances the uncertain water resources. Olive trees represent a major component of farming systems around water reservoirs since their cultivation in undertaken by the abundant anf often under-employed family labour force. It is also an income generating activity during months of serious financial hardship. It orients strategies and determines the technical, social and economic behaviour of farmers in semiarid areas where olive trees are planted. The present article investigates the status and characterizes olive tree patterns in farming systems around the hill lakes in Siliana region.
