Soil health management in Ethiopian highlands is crucial for sustainable food security and livelihood stability. However, there is a need to evaluate the effectiveness of various programmes systematically. A mixed-method approach will be employed, integrating quantitative data analysis with qualitative interviews. Soil quality indicators will be measured through standardised protocols using statistical models such as linear regression ($y = β_0 + β_1X + ε$) to estimate the effect of programme interventions on food security and livelihood stability. A significant proportion (p<0.05) of households reported improved soil health, leading to enhanced crop yields and income stability. The methodological framework provides a robust tool for evaluating future programmes aimed at improving soil health in Ethiopian highlands. Future research should focus on long-term sustainability and cost-effectiveness of the recommended interventions.
