Item Ziziphus Spina-Christi population status and socioeconomic contributions in Tanqua-Millash Woreda, Tigray, Ethiopia(Mekelle University, 2025-01-25) Aregawi Gebremeskel AregawiTrees are crucial for the livelihoods and food security of rural households, especially those providing direct and indirect benefits. This thesis focuses on Ziziphus Spina-Christi, aiming to examine its population status, production capacity, economic contribution, and social importance in the Tanqua-Millash Woreda of Tigray, Ethiopia. Data were collected using purposive sampling from two Tabias known for Ziziphus Spina-Christi prevalence, along with systematic random sampling of 138 households. Quantitative data were gathered through structured questionnaires, while qualitative insights were captured through key informant interviews, enhancing the understanding of community practices related to the tree. Tree height metrics were measured, and statistical analysis was performed using SPSS version 23. Findings indicate notable differences in the population status of Ziziphus SpinaChristi based on sex and wealth classification. The average male abundance was higher at Sheka-tekli (19) compared to Amdi-woyane (13), while females exhibited a higher mean at Sheka-wekli (20) than at Amdi-woyane (15). Location significantly affected the population status, with Sheka-tekli (19) exceeding Amdi-woyane (14) (p < 0.001). There were also significant variations across wealth categories (p = 0.029), showing that Rich groups had a greater abundance than Poor (p = 0.005) and medium groups (p = 0.043). The regeneration status did not show an inverse J-shape, indicating a concerning population health. Production varied by tree size class, location, gender and wealth status. Ziziphus Spina-Christi plays a vital role in local economies, contributing an average of 9,569 Ethiopian birr to annual household income. Wealthier households reported higher economic returns (11,791 birr) compared to poorer ones (7,056 birr), with male respondents yielding more than females. Beyond its economic value, Ziziphus Spina-Christi significantly enhances food security through its fruits, livestock shade, and materials for traditional medicine and construction. This study highlights the urgent need for effective conservation and sustainable management strategies to bolster community resilience against climatic challenges
