Annaba, Algeria's fourth largest city, has acquired national and international importance due to its openness the Mediterranean Sea. Over last ten years, rapid sprawl continued exacerbate situation, leading increased consumption of space, particularly green structures. The main objective this study is assess changes in land use cover (LULC) over 30 focusing on structure future metropolis.
 Google Earth Engine (GEE) was used explore classification using random forest algorithm. A spatial model between 1984, 2004 2021 also generated.
 principal drivers change are human activities urbanization, including fires clearing.The pattern mainly inappropriate investment policy uncontrolled urbanisation. This explained by results conversion processes 1984 2021. comparison shows a decline forests land, urbanised cropland, bare or other land.
