Drought is a major factor in a rangeland environment. It has major effects on rangeland resources, on productivity and thus influences financial and social aspects. Warning of incipient drought should aid management preparations. This paper details an approach based on the use of soil water balance data from a plant growth model (GRASP) to estimate the probability of rainfall adequate to fill the soil profile. Preliminary estimations from historical climatic data for Charleville indicate that the technique may provide some warning of the onset of drought, with the possibility of prediction on a monthly basis.
