Abstract

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 relationship between Vulnerable drought areas in Bali-Nusa
Tenggara with El NiƱo phenomena. Bali-Nusa Tenggara islands are a chain of islands that
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. It also indicated in the spatial
pattern relationship between ENSO and SPI in Bali-Nusa Tenggara islands. This study
indicates that remote sensing data such as TRMM 3B43 has the capability to be used as a
data source to analyze the spatial patterns of vulnerable drought areas, particularly in the
Bali-Nusa Tenggara Islands. In addition, the TRMM data also possible to be used as a data
source to analyze the vulnerable drought areas in other parts of Indonesia.
