The study aims to assess how climate information affects farm-level decision-making among farmers in the Pra River Basin of Ghana.
Interviews with 382 farmers were conducted to evaluate their access to and reliance on climate information.
Assessment of the performance of ECMWF seasonal forecasts in relation to farmers' needs.
Farmers prioritized rainfall onset, amount, and cessation, with ECMWF-S5 meeting only the rainfall amount need at a 1-month lead time.
ECMWF-S5 showed the highest forecasting skill with a correlation coefficient and RMSE ranging from 40.31–52.84 and 68.85–75.82, respectively.
It is recommended to combine ECMWF-S5 forecasts with indigenous techniques to enhance forecasting accuracy and lead times.
