In Poland one can observe a lack of suffi cient amount of rainfall during plant growth season. This results in the occurrence of agricultural drought and the consequent drop in crop yields. For the early detec-tion of drought, satellite images taken by environmental and meteorological satellites have been used. On the basis of these images various plant indices like NDVI, VCI and TCI have been determined. Analysis of changes in these indices allows preparation of maps showing the emergence and extent of drought. These vegetation indices were also used in the model of cereal yield forecast. Comparison of the results provided by the model show a high conformity with the results published by the Polish Central Statistical Offi ce. Elaborated model estimating crop yield reduction due to drought, based on satellite-derived data allows venture of measures to mitigate results of drought and prevent the lowering yields by artificial irrigation.
