The spectral indices, which used in this study were: TheNormalized Difference Vegetation Index (NDVI) and Vegetation ConditionIndex (VCI). The change analysis presented in this study is based on thestatistics extracted from the six resultant drought maps. The final resultswere illustrated that drought area in the region had a noticeable increasecompared with no drought area. The results revealed that percentage of nodrought area ranged between (7%) and (17%) during the period from 1988to 2018.
