Abstract
The present work focuses on the past (1985) and current (2018) status of the Naama’s Sabkha, particularly its salinity, vegetation, and water status. The acquired results will be useful for the preservation of Sabkha biodiversity. The representative sampling allowed us to make 136 soil samples over two depths: topsoil (0-4 cm) and down soil (4-30 cm) layers. The salinity analyses revealed that the maximum values are of the order of 115.3 g/l at 4 cm and 80.3 g/l at 30 cm depths. Regarding the soil conductivity, the highest values recorded at 4 cm and 30 cm are respectively 198.4 mS.cm-1 and 141.89 mS.cm-1. At the same time, the results highlight that the Sabkha soil is weakly alkaline with strongly alkaline, respectively. The diachronic study based on the NDVI analysis of the Landsat_5, Landsat_8, and Sentinel_2 satellite imagery showed the installation of varied vegetation during 33 years. The outcomes of the statistical analysis of NDVI1985 and NDVI2018 (p-value
