The Philippines is vulnerable to the impacts drought, which resulted to millions of dollars of damages in crops and livestock. In this study, a combined drought index (CDI) was developed to monitor the transition from meteorological to agricultural drought. It combines monthly land surface temperature (LST), normalized difference vegetation index (NDVI), and the three-month rainfall represented by the standardized precipitation index (SPI-3).
