The map below shows the forecast yield of cereals (Maize, Sorghum, Millet) for the Sahelian countries for the 1998 cropping season, as percent of the average yield of the last five years (1993-97). The map is obtained by applying to each country a yield function related statistically to the period 1982-97, the output parameters from the FAO crop specific water balance model to the crop yield. For 1998, the water balance model uses average rainfall from 1st October to the end of the crop cycle.
