The research aims to use remote sensing techniques in the study of the manifestations of desertification for the period 2000 - 2013 in the (Nineveh Governorateُs Island as a model ) .

A map of the earth cover (2000) and (2013) is designed, classified and analyzed using contemporary geo-technology , As the land cover is classified for the year 2000 to five categories: (Vegetation, arid land, wind deposits, sand dunes, saline areas) The total area of each category was got to (4830,26, 5804,29, 9885.52, 5506.82, 500.11) km2 respectively (17.86, 21.46, 36.55, 20.36 and 1.85%) respectively, While the area and proportions of manifestations of desertification increased in 2013, which led to its spread in the study area, The areas (vegetation cover, barren land, wind deposits, sand dunes, saline areas) constituted (2023,24, 6343.52, 10253.53, 7398.41, 800.20 )2 km respectively (7,48, 7,48, 37.91, 27.35, 2.96%), respectively, of the total land cover ratios for 2013 .

The results revealed that there were clear changes in the prevalence of desertification in the study area, The study also found the establishment of geological layers and their design and construction using geographic information systems through which a map of the degrees of desertification risk was designed based on the spatial analysis model to reach several conclusions and recommendations to address the worsening manifestations of desertification in the study area .
