Field research stations play a critical role in agricultural development in Senegal. These stations provide essential data for cost-effectiveness analysis to inform policy decisions. A mixed-methods approach incorporating econometric techniques was employed. Specifically, a fixed effects model will be used to analyse the data collected from multiple years at different locations in Senegal. There is evidence of varying costs associated with maintaining these stations across different geographical regions, suggesting that resource allocation could be optimised for better cost-effectiveness. The study concludes that a detailed methodological assessment and econometric analysis are essential for understanding the optimal configuration and operation of agricultural research stations in Senegal. Based on findings, it is recommended to prioritise investments where costs are lower but outcomes are still significant, thereby maximising resource efficiency.
