This study assessed the effects of Prosopis juliflora invasion on livelihood diversification and evaluated the determinants of livelihood diversification in Awash Fentale District and Amibara District in the South Afar region of Northeast Ethiopia in 2017-2018. Using random sampling method, 154 households and 2 focus groups composed of 10 individuals were selected from four sites in the two districts. The relationship between P. juliflora invasion and incomes obtained from P. juliflora varied across the study sites. In Awash Fentale District and Amibara District, 11.0% and 3.2% of households, respectively, earned income from P. juliflora charcoal production. In total, 14.3% of households were involved in this activity. In addition, 19.9% of households earned income from selling P. juliflora pods and wood materials. With the exception of income from P. juliflora charcoal production, the sex of households did not affect incomes from other livelihood activities. Moreover, household educational attainment significantly affected income obtained from vegetables, fruits, and cereal crops. Reversing the severe invasion of P. juliflora and other negative impacts on grazing and woodlands in the region is advisable through integrated natural resources, pastoralist participation, and multidisciplinary research strategies.
