Abstract

Agricultural drought causes many economic and social problems in various communities. Advanced Geographic Information Systems (GIS) and remote sensing techniques play a significant role in the mapping and monitoring of agricultural drought. The main objective of this paper is to monitor agricultural drought using a remote sensing-based vegetation health index (VHI) derived from Landsat 8 during 2020 and 2021. VHI was calculated based on temperature condition (VCI) and thermal condition of vegetation (TCI). Both indices were generated from Normalized Difference Vegetation Index and land surface temperature (LST) data respectively. The result indicates that there is no any  extreme drought occurred  in the research area. The VHI classes demostrates that large area of study site faced drought from moderate to mild from 2020 to 2021. Mild drought, covering an area, 50.2 percent in 2020 while 64.5 percent in 2021 was registered all across Mezohegyes. This is due to the rising of NDVI from 0.46 in 2020 to 0.55 in 2021 whereas LST decreased slightly from 62oC to 51oC respectively.
