Figure 5.7 (a) The NDVI monthly values (bars) and long-term (1982-2000) means (thick
lin e) for Mali during 1983-85, and (b) the annual variation in millet production for Mali
du ring 1981-2000.

During the period from 1983 to 1985, Mali, like other Sahelian coun-
tries, experienced one of the most severe droughts in recent history. This
region has only one growing season from June to October, with a peak
rainy season in July-August. The mean NDVI vegetation profile shows this
growing season pattern, with a peak in NDVI during August-September
every year. During the 1983-84 period, rainfall was below normal over
most of the Sahel region, resulting in below-normal NDVI values. This
