Monitoring drought and its management became easier with the help of remote sensing..several drought monitoring indices can be used to monitor drought condition. The PDSI and VHI are the natural and actual agricultural drought indices. These relationships were stronger with longer temporal aggregations and during the wet and hot seasons (summer), showing a significant role in the triggering of droughts in Argentina. The Lincoln Declaration on Drought Indices recommended that a working group withrepresentatives from different regions around the world and observers from UN agencies andresearch institutions (and water resource management agencies for hydrological droughts) beestablished to further discuss and recommend, by the end of 2010, the most comprehensive indexto characterize agricultural drought.

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.
