Paper Abstract

The necessity for accurate and real time crop monitoring is particularly felt in arid and semiarid environments, because temporal and geographical rainfall variability leads to high interannual variations in primary production and often increases the risk of severe famines. In these cases remotely sensed data, available for wide areas and with high temporal frequency, are an important tool for crop production monitoring and harvest forecasting. In particular, GAC NDVI images derived from the NOAA-AVHRR sensor have already been used for this aim in the Sahelian area of Africa, obtaining good results. In the present paper, a similar approach is tested for the early estimation of cereal crop yield in North African countries. The first results indicate that this estimation is possible especially when stratifying the land surface in ecologically homogeneous zones, identified by supervised or unsupervised clustering techniques.
