“…In the south-eastern rift valley escarpment of Ethiopia indigenous agroforestry systems sequestered a total biomass carbon stock averaging 67 Mg ha −1 with trees accounting for 39–93 % of carbon stock ( Negash and Starr, 2015 ). Betemariyam et al. (2020) have reported that homegardens and adjacent coffee based agroforestry systems reduce emissions and enhance carbon sinks on agricultural landscapes and so can be used in other mixed cropping systems on cropland, pastureland, or rangeland to address the threats of climate change while also improving microclimatic conditions ( Teketay and Tegineh, 2012 ).…”

Tree planting has a long history in Ethiopia and managing indigenous multipurpose trees is widely adopted by farmers, as a dominant feature of agricultural landscapes. Farmers manage different indigenous multipurpose tree species within agroforestry practices. But variability in agroecological conditions causes inconsistency on tree species selection, their intended benefits and ecological services. Management practices and current constraints on them were also the major issues on indigenous multipurpose agroforestry tree species in Ethiopia. Therefore, this article was initiated to review on indigenous multipurpose agroforestry tree species in Ethiopia, management practices applied to them, their productive and service roles and constraints. It found that Cordia africana, Millettia ferruginea, Erythrina brucei and Olea capensis are the major indigenous multipurpose tree species used in agroforestry systems in southern Ethiopia. Croton macrostachyus, Vernonia amygdalina, Faidherbia albida, Acacia nilotica, Acacia seyal and Grewia bicolour are found in the northern part of Ethiopia. Albizia gummifera, Cordia africana , Croton macrostachyus , Ficus vasta and Vernonia amygdalina are also found in the central highlands of Ethiopia. They are established through natural regeneration and farmers apply pruning, pollarding and coppicing tree management practices to harmonize their survival with integrated crops. Fruit, fodder, wood, timber and cash generation are the major productive roles of these tree species. In addition to these, they also have agroecological services through improving soil fertility, controlling erosion, mitigating climate change and conserving biological diversity. Despite their considerable uses and services; inadequate research and extension; shortage of knowledge; the expansion of cash crops and the small size of land holdings constrain the sustainability of these tree species. The government could encourage the wider use of agroforestry practices by policies to expand research and extension services. In addition to this, policy makers and agricultural development interventions should be encouraged to make more informed decisions regarding further research on indigenous multipurpose tree species in Ethiopia.

“…Co eebased agroforestry system is among the most structurally complex and diverse forms of agroforestry systems practiced for centuries in Ethiopia [4][5][6]. Its upper strata are dominated by overstory shade trees (fruit and timber trees) and commonly managed in association with other perennial crops such as co ee (Co ea arabica L.) and enset (Ensete ventricosum) and annuals that form a seemingly unbroken vegetation cover [3][4][5][7][8][9][10].…”

There is a limited effort in Ethiopia to study scientifically the ecological features of traditional coffee-based agroforestry systems. This study was initiated to determine the structure, composition, and carbon stock of woody species along an elevation gradient of a traditional coffee-based agroforestry system in Yirgacheffe district, southern Ethiopia. Woody plants’ inventory was conducted in thirty-eight sampling quadrats (20 ∗ 20 m) along five elevation contours and eight transects. Thirty-eight soil samples were taken from randomly selected subplots at 0–30 cm soil depths. In this study 32, woody plant species representing 23 families were recorded. Species richness ranged from 13–17 along the elevation gradient. Woody plant diversity indices appear to have a slight variation with increasing elevation gradient. Shade tree and coffee shrub density, DBH, and height showed significant variations along the elevation gradient. Total aboveground woody biomass carbon stock along elevation gradient ranged from 11.07 to 27.48 Mg·ha−1. Soil organic carbon stock was slightly different across elevation gradients with a mean range of 83.91 to 89.29 Mg·ha−1. These indicate that the agroforestry system has significant potential of storing and enhancing ecosystem carbon stocks across all the elevation gradients. The findings generally show that agroforestry systems in the study area are diverse, structurally complex with significant carbon storage in the soil and woody biomass.
