Title: Sudan Vegetation Cover Assessment, Using NOAA-AVHRR Data, for the Period "Between 1982-1999"
Author: Ahmed, Hanadi K.; Warrag, Essam I.
Abstract: The objective of this study was to assess changes in the vegetation of Sudan between 1982 and 1999 by using remote sensed images and to compare the vegetation with that of Harrison and Jackson of 1958. NOAA-AVHRR data was used and processed by Maximum Value Composite of the Normalized Difference Vegetation Index. Vegetation maps were produced for the years 1982, 1984, 1987, 1990, 1993, 1996 and 1999. Also, maps for differences using 1982 as reference map were produced.. The maps didn't show differences between 1982 and 1999 except in the southern parts where the vegetation got denser with the years. Large change was observed when compared with Harrison and Jackson 1958. The area north of latitude 16° has changed to desert while that between Latitudes 12°N and 16°N changed from low rainfall savanna to desert and semi-desert.
