This study assesses the food security condition of Acacia-based agroforestry (ABA) user and non-user households in Awi Zone highlands, Ethiopia, using a composite approach. Purposive and random samplings were employed to select sample districts and households. Data were collected through questionnaires, discussions, and interviews, and analyzed quantitatively and qualitatively. Results showed that 42.2% of the households (46.9% ABA-users, 37.5% non-users) were food-secure, while 57.8% were food-insecure. ABA-users' composite food security index was significantly higher than non-users (P<0.05), signifying ABA's contributions. Livestock and farmland size, participation in off-farm activities, irrigation access, plantation experiences, and perceived soil quality positively affected food security, while age, family size, credit access, and market distance negatively impacted it. Addressing lavish sociocultural practices, and intensifying agroforestry helps to combat food insecurity. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the size of Senegalia mellifera seeds and determine the most effective scarification techniques to improve germination. The experiment, conducted at Botswana University of Agriculture and Natural Resources, involved ten presowing treatments, including control, nicking, soaking in sulphuric acid for different durations, and boiling water for varying periods. A completely randomized design (CRD) was used for the experiment. Germination data was transformed using arcsine to meet normal distribution requirements and then analyzed using analysis of variance (ANOVA). The results showed that the presowing treatments had a statistically significant effect on germination (P<0.00001). Seeds treated with sulphuric acid, nicking, and those left untreated exhibited the highest germination rates, while seeds treated with boiling water showed the lowest germination percentages. These findings indicate that the seed coats of S. mellifera are permeable to water and air, and presowing treatments do not show any significant effect on the successful germination of S. mellifera seed.

Acacia decurrens (hereafter Acacia) agroforestry system has been expanding rapidly in the northwestern highlands of Ethiopia. The agroforestry system provides multiple eco-environmental services; however, there is inadequate quantitative evidence on its livelihood benefits. This study, therefore, investigated the livelihood benefits and challenges of Acacia-based agroforestry system in the Awi area, Northwest Ethiopia. Data was collected through household survey quetionnaires (296 randomly selected Acacia growers), focused-group discussions, interviews, and observations. A combination of quantitative and qualitative methods was used for the data analysis. The findings showed that crop production, charcoal making, animal rearing, and fuelwood selling were the major sources of livelihood. Notwithstanding the complex challenges (Acacia pests/diseases, traditional charcoal-making, limited road access and market opportunities, negative human-health impacts, and high production cost), Acacia-based agroforestry positively affected farmers livelihoods. Comparatively, the natural, physical, financial, human and social capital indices of farmers were higher by 0.25, 0.24, 0.43, 0.25, and 0.06, respectively, in the post-than pre-Acacia periods. The overall livelihood index of farmers increased from 0.47 (pre-Acacia) to 0.71 in the post-Acacia period. The study concluded that this agroforestry practice has immense livelihood benefits, although diverse challenges question its sustainability. Therefore, short and long-term strategies should be designed to strengthen the opportunities and address the challenges. [ABSTRACT FROM AUTHOR]
