The environmental impact of agricultural practices in Rwanda is a matter of concern, particularly regarding yield improvement and sustainable land management. The review employs rigorous methodologies including comprehensive data extraction from peer-reviewed articles, meta-analytic techniques, and thematic synthesis of findings. A significant proportion (45%) of the analysed monitoring networks demonstrated a positive correlation between network design and yield improvement measurements, with multilevel regression analysis providing robust estimates. The systematic evaluation highlights the importance of well-designed regional monitoring systems in Rwanda for accurately measuring yield improvements, contributing to sustainable agricultural practices. Enhanced collaboration among stakeholders is recommended to ensure data uniformity and improve the accuracy of yield measurements through multilevel regression analysis. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
