Regional monitoring networks are crucial for assessing agricultural productivity in Ghana. However, their effectiveness is often underpinned by methodological challenges and requires rigorous evaluation. The study will employ DiD models to compare pre- and post-intervention outcomes between control and treatment groups. Data from multiple monitoring sites will be analysed to assess network reliability. A preliminary analysis indicates that the regional monitoring networks in Ghana show a significant improvement (p <. 05) in yield measurements, highlighting the need for further validation. The DiD models demonstrate potential as robust tools for evaluating the reliability of agricultural monitoring systems. Further research is recommended to validate these findings across different regions and time periods. Implementing standardised protocols for data collection and regular model re-evaluations are essential for maintaining the integrity and reliability of regional monitoring networks in Ghana.
