​Jordan is a food-deficit country. Jordan’s population reached approximately 10 million in 2019 and has an annual growth rate of 3.3%. This increase will exert heavy pressure on the kingdom’s fragile natural resource base. The total imports of food commodities still exceed exports, so Jordan is a deficit country with respect to its food supply chain. Data from the Marfraq governorate were used to evaluate the effect of drought on food security in Jordan. This governorate was chosen because most of its land receives low levels of precipitation. The crops selected for analysis were rain-fed crops: olives, wheat, and barley. The precipitation data series were examined for normality distribution, and they were found to be normally distributed. Six drought severity classes were estimated by the Mafraq Governorate during 1995–2017. ​
