Abstract Field measurements of primary production in semi-arid grasslands in three Sahelian countries over a period of 8 years are analysed in conjunction with multitemporal sums of vegetation indices derived from the NOAA spacecraft's advanced very high resolution radiometer (AVHRR). The results demonstrate that there is a strong linear relationship between the satellite observations of vegetation indices and the seasonal primary production in the range 0-3000 kg ha−. The confidence intervals of estimation of production were in the range ±61-161 kg ha−.
