Abstract: Information on Land Use and Land Cover (LULC) changes and the driving forces behind such modifications underpin a proper understanding of the dynamics of LULC changes. This study aimed to analyse the dynamics of LULC change trends and its driving factors in Jimma Geneti District (JGD) for the year 1973–2019. Five satellite images downloaded from USGS were used to analyze and assess the geospatial and temporal changes in LULC. In addition, in-depth household interviews, key informant interview, focus group discussions (FGD) and field observations were used to address the drivers of LULC changes. The result showed a decline in forest land from 8632.5 ha (20.9 %) in 1973–5647.23 ha (13.7 %) in 2019. The study further revealed that the total of forest land cleared between 1973 and 2019 was estimated to be 2985.27 ha (7.22 %). In other words, 34.6 % of the forest cover that existed in 1973 was lost. Similarly, wetlands declined from 9919.5 ha (24.0 %) in 1973–2000.24 ha (4.8 %) in 2019. Similarly, wetlands declined from 9919.5 ha (24.0 %) in 1973–2000.24 ha (4.8 %) in 2019. On the other hand, cultivated land has increased from 18617.0 ha (45.1 %) to 27708.1 ha (67.1 %). Similarly, the increment in settlement areas has elevated from 908.7 ha (2.2 %) to 4436.46 ha (10.7 %) during the same period. Agricultural expansion, cutting trees for various purposes (such as firewood, charcoal and construction material), overgrazing and the expansion of settlements, were identified as the major proximate causes of these changes. Moreover, the major underlying drivers of LULC changes include population growth, changes in policy and institutions, poverty and lack of awareness on the importance of natural resource conservation for sustainable livelihoods. From this study, it can be concluded that JGD has experienced a significant change in LULC over the past 46 years and were affected both positively and negatively. Hence, a wide range of policy packages are required for sustainable land management practices which take in to account synergies and trade-offs between the various land uses in the study area. The national and local governments should enforce sustainable land management approaches through integrating land use planning and management into all development programmes and projects.
