The main objectives of the study were to examine the magnitude and rate of the current status of Accacian decurrens expansions, to identify the driving force of the local communities to shift, crops to tree plantation land use, to evaluate its economic benefits and its problems and opportunities for the sustainable future tree plant production in Fagita Lekoma district. ArcGIS 10.4 and ERDAS Imagine 2014 software was used for spatial analysis and land use classification. Landsat images were used to generate the land use maps by using the maximum likelihood algorithm of supervised classification. The results show that cultivated lands, grasslands, and wetlands are declining while forests and settlements are increasing. Forest cover was the most widespread land use, increasing by 210% during the study year. The conversion rate of forest land is 15.1%, which is the highest value in the general study period of the district. The rationale behind the expansion of forest land use is the introduction and spread of new species of trees known as Accacian decurrens plantations. Accacian decurrens forestation is the main cause of the change of use, system from arable land to forest system. These plantation-based land uses have been shown to be a way to increase economic benefits, employment opportunities and reduce soil erosion and increase soil fertility in the area.
