Field research stations in Tanzania play a crucial role in agricultural development by providing data for policy-making and improving crop yields. However, their effectiveness can vary significantly across different regions. A comparative study design was employed, analysing data from multiple field research stations in Tanzania. Multilevel logistic regression models were used to assess system reliability across different levels (national and regional). The multilevel analysis revealed that climate variability significantly impacts the success of field research stations, with a 70% increase in failure rates during drought conditions. This study provides valuable insights into the resilience of agricultural research systems under varying environmental pressures. Policy makers should prioritise investments in infrastructure and support for researchers to enhance system reliability during climatic extremes.
