Abstract

Drought is a natural phenomenon, which occurs in most regions in the world, caused immense damage in agricultural production and seriously affected on the environment. Droughts often occur on a large scale, so traditional observation techniques for drought monitoring are dificult, time consuming and costly. Remote sensing data provides information on the Earth’s surface at different spectrum channels and and wide coverage has been used effectively in monitoring and severe drought. This paper presents the results of the study on drought assessment in Bac Binh district, Binh Thuan province using LANDSAT multispectral imagery based on normalized difference drought index (NDDI). The results obtained in the study can be used to create drought level map and provides information to help managers set measures to minimize damage caused by drought.
