Field research stations in Ethiopia have been established to study environmental impacts over time, but their cost-effectiveness remains uncertain. A longitudinal study employing a quasi-experimental design will assess the performance of research stations in terms of resource allocation versus outcomes achieved. The analysis revealed that station B, with an investment-to-output ratio of 3.5:1, exhibited superior cost-effectiveness compared to station A (2.8:1). Station B is recommended for replication as a more efficient model for future research endeavors. Future studies should prioritise similar cost-benefit analyses and consider scalability of the findings.
