Désertification et barrage vert en Algérie : le cas des Ziban

Abstract : The study of desertification in the Ziban Mountains allows to reconstruct the stages of the erosion evolution since about 4 000 years. It does not yet allow to assert that the mobilization of the aeolian sands is rather due to aridification than to the extension of ploughing but it suggests two scenarios. Further datations will permit to choose between them. Anyhow, the "Green Dam" can not reach its goal (i.a. to stop the advance of saharan sands to the north) because on the contrary those sands move towards the Sahara desert.
