Drought Risk Assessment In Iraq Using Remote Sensing And GISTechniques
Agricultural drought
Meteorological drought

Standardized Precipitation Index (SPI).
This paper aims to investigate the drought levels in Iraq using Remote Sensing and
GIS Techniques. Meteorological and Agricultural droughts were calculated based on
Standardized Precipitation Index (SPI) and Anomaly of Normalized Difference
Vegetation Index (NDVI), respectively. The drought risk maps were prepared by
calculating the classes frequency of droughts. Finally, a resultant risk map was
obtained by integrating agriculture and meteorological drought risk maps. The
results indicated that 14.4% area has Slight drought, 61.6% area face moderate risk,
23.2% area face severe risk and 0.8% area face very severe risk within the study
area. It was evident from the study that northwest of Iraq is more prone to drought.
