Agricultural drought in Iran is considered as a natural disaster especially for the farmers. Although nobody can stop drought, but if its nature and its characteristics are studied, it can be predicted and the results can be reduced. This article studies drought in the province of Sistaan and Balouchestaan and the drought predictability in the province has been done base on a model that is made according to SPI indicator, percent indicator of normal and Markov chain. The results of the study show that this region is sensitive to average and short term drought and most of the drought that have happened in the area have not been harsh ones; and this phenomenon can mostly happen in the central areas of the province.
Keywords: Drought, SPI, percent indicator of normal, Markov chain, Sistaan and Balouchestaan.
