Abstract
This study focuses on evaluating regional monitoring networks in Rwanda to assess their cost-effectiveness. A mixed-method approach combining quantitative analysis of monitoring data with qualitative interviews was used. The quasi-experimental design involved comparing baseline and post-intervention performance metrics across monitored regions in Rwanda. The results indicate that a distributed network model, which involves multiple smaller stations rather than fewer larger ones, showed a cost reduction of approximately 15% compared to the traditional centralized approach without compromising data accuracy. This study concludes with evidence supporting the use of distributed monitoring networks in Rwanda for cost-effective and efficient regional physics monitoring. Based on findings, it is recommended that future investments in regional physics monitoring should prioritise the deployment of a network model similar to the one found effective in this study. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
