Pemetaan Daerah Rawan Kekeringan di Bali-Nusa Tenggara dan Hubungannya dengan ENSO Menggunakan Aplikasi Data Remote Sensing

In this Study, the use of SPI (standardized Precipitation Index) combined with remote sensing data is performed to map vulnerable drought areas in Bali-Nusa Tenggara regions. ANalysis also carried out to find the reletionship between Vulnerable drought areas in Bali-Nusa Tenggara with El Nino phenomena. Bali-Nusa Tenggara islans are a chain of islandthat has a semi-arid climate type and resulted vulnerable to meteorological drought. therefore, mapping of vulnerable drought areas in the region necessary to be carried out. The spatial pattern of the annual average value of SPI-6 in Bali Nusa Tenggara areas in 1998-2010 indicates the Spatial distribution follows the ENSO events.
