This paper aims to provide a comprehensive review of the historical trajectory of deforestation in Ethiopia, spanning an extensive timeframe and exploring its major driving factors. Over the span of three millennia, Ethiopia has experienced persistent deforestation, resulting in a significant reduction of its once-large forest and woodland resources. Currently, small, degraded forests and woodlands exist in isolated patches, located in remote areas such as the southwest and southeast. Major deforestation in Ethiopia unfolded progressively, first along a north-south axis and more recently shifting from the highlands to the lowlands. The northern and central highlands lost most of their natural forests before the turn of the 20th century, while significant loss in the southern highlands occurred over the past 150 years, and in the lowlands over the past 50 years. This deforestation is primarily attributed to the expansion of ox-plow agriculture and population pressure resulting from natural birth and internal migration. Despite efforts to counter deforestation and promote restoration, mostly since the 1970s, successes remain limited. A noteworthy exception in this regard is the introduction of Eucalyptus during the turn of the 20th century and the subsequent expansion of it, mainly in the form of small-scale farmer-led farm forestry. Today, Eucalyptus become the most preferred, well-adapted, widely planted, and the major supplier of wood materials in Ethiopia. The limited success in restoration is attributed to the reliance on campaign-based strategy, lack of private sector involvement, the intertwining of restoration with political agenda, and poorly defined property rights on land, forests, and trees. The consequences of deforestation and resultant environmental degradation have profoundly influenced the socio-economic dynamics of Ethiopia, giving rise to issues such as food insecurity, poverty, migration, and political instability.
