This study was conducted to monitor the agricultural drought in
the Middle Euphrates area, Iraq during the period from 1988 to 2018.
Multispectral Landsat TM, ETM+, and OLI images were used. The images
dated 1988, 1993, 2000, 2005, 2010, and 2018, which obtained during
growth months of plants (January, February, March, November, and
December).A computerized drought monitoring was adopted using ERDAS
Imagine 2015, ENVI 3.2, and ArcGIS 10.5 environments to process and
analysis the data. The spectral indices, which used in this study were: The
Normalized Difference Vegetation Index (NDVI) and Vegetation Condition
Index (VCI). The change analysis presented in this study is based on the
statistics extracted from the six resultant drought maps. The final results
were illustrated that drought area in the region had a noticeable increase
compared with no drought area. The results revealed that percentage of nodrought area ranged between (7%) and (17%) during the period from 1988
to 2018. The extremely and severely drought classes recorded high
percentage followed by moderately and mild drought in the region. From
this study can be concluded that there is a high rate of drought in the
region, especially in its southern and western parts.
