This study aimed to assess environmental contribution of tree-based agroforestry practice to local people around Jimma town, southwest Ethiopia. Three sites namely; Mazora, Waro kolobo and Merawa were selected purposively from Mana, Dedo and Kersa districts in the Jimma zone respectively. Totally, 199 of households were calculated and proportionally distributed to three sites then randomly selected. Semi- structured and structured questionnaires were employed to collect the data. The collected data was analysed using descriptive statistics. A result obtained showed about 67.2% of respondents in Mazora and Merawa, whereas 73.8% in Waro kolobo site responded that integration of tree within crop farm is assisting soil and water conservation. Besides, 46.6%, 41.5% and 39.5% of sampled household also responded that tree in coffee land contribute incredible benefits in enhancing soil fertility/soil moisture in Mazora, Waro kolobo and Merawa sites respectively. More trees were recorded in home gardens across the study sites. Persea americana, Eucalyptus camaldulensis and Acacia abyssinica were the most preferred tree species in the home garden, woodlot and pasture land in the study sites, respectively. In a coffee farm, Millettia ferruginea, Albizia gummifera, and Acacia abyssinica were the most important tree species in Mazora, Waro kolobo and Merawa sites, respectively. In general, tree-based agroforestry, land use practice is the most crucial for improving environmental quality and providing cultural values. Therefore, Tree-based agroforestry land use practice should be encouraged in the study sites.
