The rainfall data for the coastal region of Ivory Coast, a forest region suitable for oil palm growing, for the past thirty or more years were analysed and examined alongside the impact of water deficit on palm oil production. The results show that the overall trend of rainfall in the forest region has been on the decrease. Monthly water deficits were higher in south-eastern Ivory Coast than south-western. Those recorded 30 and 6 months before the harvest explained 79% of the production variation. This was due to the negative effect on the number of bunches. The results allow it to be said that the overall decrease in rainfall in the southern forest region of Ivory Coast is a threat to the country’s oil producing industry.
