Precision agriculture techniques have shown promise in increasing crop yields globally, but their application is still nascent in Rwanda's highland regions where coffee cultivation thrives. A mixed-methods approach was employed, combining quantitative data from farmers' satisfaction surveys with qualitative insights from field observations. Precision agriculture tools were used to monitor soil moisture and nutrient levels, while a Bayesian hierarchical model was applied to analyse yield variability across different plots. Initial analysis indicated that precision agriculture significantly increased coffee yields by an average of 15% compared to conventional farming practices in the study area. Farmer satisfaction scores improved from 70% to 85%, with themes including better resource allocation and environmental sustainability. The implementation of precision agriculture techniques has led to notable improvements in both yield and farmer satisfaction, providing robust evidence for its effectiveness in Rwanda's highlands coffee cultivation context. Further research should focus on scaling up these practices across larger areas and investigating the long-term impacts on soil health. Policy recommendations include financial incentives and training programmes for farmers adopting precision agriculture methods.
