摘要

The parkland agroforestry practice, a crucial ecological and socioeconomic practices in Northwestern Ethiopia, is facing a decline due to land fragmentation. This condition requires diagnosis and design to enhance its resiliency. This study aims to investigate the role of parkland agroforestry species in the Gungua district of northwest Ethiopia, addressing the existing gap in research on this issue. Soil samples for the analysis of selected physico-chemical properties were collected from various distances beneath the canopy of Albizia gummifera and Cordia africana at different soil depths in the farmer's open field. Additionally, semi-structured surveys were conducted to facilitate species management and utilization. ANOVA, multiple regression, and Chi-square analysis were performed using SAS version 9.4 and SPSS version 25. The study revealed a significant difference (p = 0.0228) in the physico-chemical properties of the soil, among tree species, distance from the canopy, and soil depth. A. gummifera exhibits higher concentrations of TN and OC. The levels of pH, TN, and OC in the soil were higher beneath tree canopies. This indicates an increase in values from open fields to tree trunk. The questionnaire survey revealed that 75% of respondents agreed that these parkland tree species function as household consumption and soil and water conservation. Nevertheless, there has been a lack of focus on planting, resulting in inadequate regeneration of these species. Therefore, collaboration among landowners, development agents, researchers, and organizations are essential for the design and implementation of effective management strategies that enhance sustainable agricultural production and ecosystem resilience.
