Abstract
Sugarcane (Saccharum officinarum L.) is considered one of the most important crops in the country since it is a source of sugar, bioethanol, and other renewable products. Cane quality is dependent on irrigation and soil moisture content thus drought vulnerability assessment is important to increase production. In this study, drought assessment was performed for sugarcane areas in Batangas, Philippines using Standardized Precipitation and Evapotranspiration Index (SPEI). Correlation analysis between SPEI and Normalized Difference Vegetation Index (NDVI) was also performed. Moderately positive correlation value of 0.5016 was obtained for the 3-month SPEI values. Driest months were identified during the months of January to April for the years 2000 to 2015 but is extended during the El Niño Southern Oscillation (ENSO) events. Wettest months frequently occur in July to December. The moderate positive correlation between NDVI and SPEI shows that NDVI values can be used to determine possible drought stress on the standing sugarcane crops. In terms of the magnitude of vulnerability to drought, vulnerability maps generated indicate Batangas have no to low vulnerability drought classification.
