Effect of urbanization and socio-economic constraints on ancient palm grove in Algeria

Oasian space in the northern Sahara has been little studied, despite its importance for the sustainability of the oasis, the Ksar of Ouargla in this case. This study focused on highlighting the extent of urbanization over the period from 1975 to 2015 and estimating areas lost due to the influence of environmental and socio-economic factors. The methodological approach adopted using, satellite images, aerial photographs and field surveys, has enabled us to estimate the losses in agricultural areas at 18.52% as a result of the above-mentioned problems and 17.23% are losses due to urbanization.
