Geospatial technologies were used in the study of variability in LULC for four years 1990, 2000, 2010 and 2020 in 15 agricultural districts, located on the left bank of the Euphrate s River, within the are a bounde d b etwee n the cities of Ramadi and Khalidiya in Anbar Governorate, located between longitudes 43° 36′ 22″ -43° 15′ 22″ ′ E and 33° 31′ 05′ - 33° 23′ 25″ N, covering an area of 18,163.5 hectares. The results showed a large variation in the types of ground covers between 1990 and 2020. Albu-Farraj recorded a very large decrease in its agricultural lands with an area of 567.45 hectares, offset by an increase in the urban or built-up area of 28.84%. While it was noted that Mahoz district recorded the largest increase in the area of the barren lands type during the study period by 30.78%. And that the classification accuracy for the LULC indicator was 100% for the types of buildings and water, while it was 83% for the agricultural lands category, and barren lands ranked last, with an accuracy rate of 75%. And that the overall accuracy of the directed rating was 86.7%, while the Kappa Coefficient was 81.1% for this rating.
