Regional monitoring networks are crucial for agriculture in Ethiopia to ensure sustainable livelihoods and climate-smart practices. A randomized field trial was conducted across four regions in Ethiopia. Soil moisture sensors were deployed at 50 sites per region for continuous data collection over one growing season. Data from these sensors were analysed using linear regression models to evaluate the relationship between soil moisture levels and crop yields, with robust standard errors accounting for measurement uncertainty. The analysis revealed a significant positive correlation (R² = 0. 75) between soil moisture data collected by the monitoring network and actual crop yield variability across regions. The reliability of regional monitoring networks in Ethiopia was robust, with consistent and accurate data collection leading to improved climate-smart agricultural practices. Enhanced training for field technicians and further validation studies are recommended to ensure high-quality data and system performance.
