Specifically, agricultural drought refers to the availability of soil water to support crop and forage growth and there is no direct relationship between precipitation and its infiltration into the soil. Agriculture is the most sensitive sector which has largely been affected by the impacts of drought. The uncertainty found in standard methods of drought monitoring has made it necessary to compare the accuracy of the drought's monitoring methods. Here, we propose using a new approach, the Normalized Ecosystem Drought Index (NEDI), coupled with modified Variable Interval Time Averaging (VITA) method, to quantify drought severity according to ecosystem transitional patterns with water availability.
