This study analyzed spatiotemporal land use/land cover change and urban sprawl of Laga Tafo Laga Dadi town in the Special Zone of Oromia, surrounding Addis Ababa city using Geographic Information System and Remote Sensing. For this study a two decades time series data (Landsat TM 1996, SPOT-5 image of 2006, and Landsat ETM+ 2016) was used and analyzed quantitatively using GIS and remote sensing data processing softwares. Maximum likelihood supervised classification of satellite imageries was applied for Image classification. The finding of the study shows that urban/built up area of the town has significantly expanded by 48.3 per cent against agricultural land loss of 42.95 per cent over the study period. This indicates that there was a major land use/land cover change of the town with the agricultural land lost to built-up area being the dominant one. An increase in the number of residents, expansion of new developments and land use/land cover change has caused rapid sprawling development of the town. The sprawling of various developments has negatively affected the economical and balanced development of land use in the town. The town is currently becoming the destination of housing estates and new industries and it became the residence place of quite large number of people commuting to- and- from Addis Ababa city in the vicinity.
Therefore, it is recommended that because the town shares boundary with the sprawling city of Addis Ababa, it is undoubtedly clear that there is a pressure on the land use plan of the town and thus Laga Tafo Laga Dadi town administration should work on ways of monitoring sprawling development and guide proper growth of the town.
