This study examines the impact of climate variability on rainfed maize production in the eastern part of the Ivory Coast. Stationarity tests show breaks in the annual rainfall regimes toward the end of the 1960s. The impact of these jump changes on the growing seasons shows that, despite significant decrease in its length after the 1970s, the main growing season remained long enough to crop maize with a short cycle. The impact on maize was assessed by simulating yields and crop water use. The simulation was based on long yield series and meteorological data using the FAO CROPWAT program to calculate water deficit and excess water conditions. The comparison of simulation outputs with the indicators for trends in production, shows that the current state of the climatic conditions does not explain the overall dynamics of maize cropping in the eastern Ivory Coast.
