Abstracts should give a pertinent overview of the work including the essential contents of the work, key ideas and results. Smallholder farmers in Northern Ethiopia face persistent challenges of soil infertility, land degradation, food insecurity, and climate vulnerability. To cope with these constraints, many farmers integrate Vachellia etbaica, a drought-resistant native tree, into their land-use systems, yet its ecological and socioeconomic benefits remain insufficiently quantified. This study assessed the effects of V. etbaica on soil properties and local livelihoods in Tsrae-Wonberta district, Tigray, Ethiopia. Soil samples were collected from 120 composite sites stratified by land use (grazing and cultivated lands), distance from trees, and soil depth (0–20 cm and 20–40 cm). Socioeconomic data were obtained through semi-structured interviews with 92 randomly selected households. Most soil properties, including moisture content, organic carbon, and total nitrogen, differed significantly (p < 0.05), decreasing with increasing distance from trees but generally increasing with soil depth. About 85% of respondents reported multiple benefits from V. etbaica, including firewood, charcoal, income generation, fencing materials, fodder, and traditional medicine. The results demonstrate that appropriate management of V. etbaica can enhance soil fertility, strengthen ecosystem resilience, and support rural livelihoods. The study highlights the species’ potential role in sustainable land management and agroforestry systems aimed at improving soil health and livelihood resilience in similar dryland environments.
