Abstract

Upper Progo watershed is one of the important agricultural areas in Temanggung Regency, Central Java. This research used the data obtained from Landsat 8 imagery to analyze the agricultural drought risk in the watershed. The hazard was analyzed using multioral data every 16 days (to the Landsat 8's temporal resolution) during the drought; from May to September 2015 combining the Landsat 8 imagery and the land's physical condition. An agricultural drought hazard map was then created by summing the hazard class score in every recording time with overlay method. The crop's vulnerability analyzed using NDVI difference, which indicates the crop's ability to survive in dry conditions. The crop's vulnerability was also analyzed every 16 days. A vulnerability map was then created by summing the vulnerability class of every recording time. The assessment of the drought risk was done by multiplying the hazard and the vulnerability scores. The result shows the high and very high classes of agricultural drought risk were located on the west research area which had a high class of hazard and vulnerability. Meanwhile, the moderate, low, and very low classes of agricultural risk were distributed evenly in the center and east area.
