The exposure to sanding risk in the Tidikelt plain is particularly ascribed to its physiographic and climatic conditions, the location of agglomerations, agricultural and socioeconomic activities in a corridor of severe wind action, increases the vulnerability to the risk as a response to the relentless human pressure, which is exerted on an arid environment already subject to climatic extremes. The use of remote sensing tool and the multitemporal Landsat imagery have allowed the regional and static observation of sand accumulation forms, and also monitoring the spatiotemporal dynamics of mobile dunes during 19 years. This gradual mutation still confronted with a noticeably low resilience from the population and the authorities.
