Abstract
This research is aimed to analyze land use/land cover dynamics of Akaki Kality sub city with their driving factors, and related environmental impacts. Spatial analysis were done majorly by using different time series satellite images that were compiled from land sat 5,7 and 8, and the supervised image classification of Arc GIS 10.4 and ERDAS IMAGINE 15 software programs were applied. Other non-spatial environmental impacts were addressed with the aid of primary data collected from households using structured questionnaire and other secondary data that were collected from Ethiopian National Metrology Agency. Similarly, Land Surface Temperature change done with Arc GIS. The 1996-2021 land uses/ land cover result analysis shows bare land decreased from 40% to 24%, which were mostly changed to construction; vegetation and forest, decreased from 43% to 23%; water bodies have shown only about 2% change and built up area increased from 10% to 46 %. Major driving factors for the increment of human induced land uses in the study area were population Growth; GDP growth and Governmental policy such as, industrialization policy and condominium-housing program. In order to minimize anthropogenic induced impacts on the urban environment in the country, government should revise investment policy and balance investment flow between inter regional and create job for youths in regional towns that can potentially reduce rural urban migration and the demand for urban land. Additionally, developing enough infrastructures to regional towns and foster private investors to invest their capital to regional towns. Moreover, vertical developments should be encouraged.
