Abstract
The objective of this study is to show the difference in vulnerability for drought among the area with different land-use history. The vulnerability was evaluated by the value of maximum NDVI in pre-drought, drought, and after drought year. Evaluated droughts were occurred in Spain, India, East, and East Africa. Drought event area was defined by the value of Drought index (scPDSI) and Soil Water (GSWP3). There are several trends in cropland, whereas no trends in grassland. In cropland, there is negative trend of maximum NDVI in drought year with decreasing the duration of cropping in India. On the other hand, opposite trend was observed in East Africa. These trends seemed to depend on the soil type which is appropriate for cropping practice.
