Thus, the study of the developed figures through regional analysis functions of GIS can
give more insight into the variation trend of spatial suitability of crop production potential in
each class of drought occurrence (longest duration and/or most intensive duration). This
analysis was performed for the region under study but a sample is presented in Figures 8
and 9.This analysis shows that regions located in class-4 risk of occurrence of the longest
drought durations have higher frequency of crop production potential with compare to regions
located in class-4 risk of occurrence of most intensive durations.
