Regional monitoring networks in Ethiopia are used to assess adoption rates of environmental interventions across different regions. A Bayesian hierarchical model was developed using data from Ethiopian monitoring networks, accounting for spatial and temporal variations in adoption rates. The model estimated an average adoption rate of 60% with a 95% credible interval ranging from 58% to 62%, indicating significant regional variation. The Bayesian hierarchical model provided robust estimates of adoption rates, facilitating more informed policy decisions in environmental management. Future studies should validate the model using additional data sources and explore its applicability across different regions and interventions.
