Abstract
Agriculture is among the most vulnerable of all sectors to drought. Droughts cause serious effects on the agricultural sector due to its heavy dependence on rainfall. In the present work, we use the Vegetation Health Index (VHI) of MODIS Data as drought indices to monitoring the drought over East Java, Indonesia. VHI is computed based on the vegetation index and land surface temperature which are very important satellite products for drought monitoring with remote sensing. VHI describes vegetation health from the combination of TCI (temperature) and VCI (vegetation condition).
