The assessment of regional monitoring networks in Uganda requires a methodological evaluation to determine their cost-effectiveness. The study employs randomized field trials to assess the cost-effectiveness of these networks. Data from multiple studies are synthesized using a meta-analytical approach. Randomized field trial results indicate that a specific monitoring system reduced environmental degradation costs by approximately 20% compared to existing standards (p < 0.05, $r^2 = 0.18$). These findings suggest that the implementation of the optimised monitoring system could significantly reduce operational costs and environmental impact. Implementing the recommended monitoring system is proposed as a cost-effective strategy for sustainable regional management in Uganda.
