Land degradation in Ethiopia is escalating due to high population density and the shift from tree-based agricultural systems, like agroforestry practices (AFP), monoculture farming. These land use changes, compounded by climate change, threaten biodiversity soil resources. Key health parameters, such as glomalin, aggregation, aggregate stability, are negatively impacted practices. Agroforestry proposed a sustainable alternative address these challenges. This study aimed evaluate effects of AFPs on stability (mean weight diameter, MWD), relationship between aggregates organic carbon (SOC). Undisturbed samples were collected 0 30 cm 30-60 depths four types: home garden (HAFP), cropland (ClAFP), woodlot (WlAFP), trees water conservation-based (TSWAFP). Results showed significantly higher glomalin-related protein (GRSP) HAFP WlAFP compared ClAFP TSWAFP (p < 0.05). also exhibited highest (SAS) MWD, followed WlAFP. findings suggest that can enhance health, ecosystem long-term sustainability, contributing restoration efforts.
