Cover Story: Ongoing global warming has increased the frequency and magnitude of ENSO which has affected the region of Asia-Pacific, including Indonesia. Multiple, long time-series remote sensing observations from 1993 to 2012, evaluating indicators such as the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Vegetation Optical Depth (VOD), were combined with measurements of the climate index and of the Multivariate ENSO Index (MEI) and with the examination of CHIRPS rainfall data to identify climate-sensitive regions. The analysis identified savanna in Indonesia as the most sensitive biome to ENSO and precipitation. Further cross-correlation analysis determined the progression of ENSO, affecting rainfall and vegetation, in the climate-sensitive region. The identified region can be kept under monitoring to timely plan mitigation actions and reduce the negative impact of ENSO on the vegetation in Indonesia. here
