Urban green areas play a great role in determining urban development strategies. Urban green provide multiple ecosystem services for human beings. Though urban green provide numerous benefits, but become deteriorated in many parts of Ethiopian towns. Therefore, this study aimed at analyzing the urban expansion and its implications of land use/land cover dynamics for green areas using geospatial techniques in Burayu Town. The study employed mixed approached to achieve the stated objectives. Three different remotely sensed data of Landsat7 ETM+ (2000 and 2010) as well as Landsat8 OLI/TIRS (2020) were used in the study. The study revealed that there was a radical change in Land Use/Land Cover (LU/LC) dynamics. The rapid expansion of the built-up areas and deterioration of vegetation covers are the two most implication of LU/LC dynamic in Burayu Town. Vegetation cover has decreased and the non-vegetated area has been increasing gradually over the study period. With the change in LU/LC for the periods 2000 to 2020, the built-up area was expanded by an area of 672.5ha. The average value of the Normalized Difference Vegetation Index (NDVI) of the year 2000 was reduced by fifty percent by the year 2020. Relatively, a high value of NDVI in 2020 is observed in the northeast and southwestern parts particularly in Gefersa Burayu and the rest parts of the study areas have low values of NDVI. Town administrators should control the rapid urban expansions and pay great attention for developing spaces for green vegetation.rnKeywords: Land Use/Land Covers; Urban Green Areas; Normalized Difference Vegetation Index
