Abstract

Drought as one the most important natural disasters directly affects the societies by water availability variations. It imposes a lot of economic, social and environmental costs and it's effects are increasing, unexpectedly. According to this phenomena extraordinary effects and changing the approach of crisis managing to risk management. We use STANDARDIZED PRECIPITATION INDEX (SPI) for monitoring different kinds of drought in great KHORASAN region. The results were applied for severity determination, relative comparing effects of drought, determining the credit ratio and the credit paying preferences in agricultural and water resources sectors. The results showed that the trends for drought variations are different during the months of year in the study regions. Additionally, the trends of SPI variations were different in various TIME SCALEs for the same region. Considering the results of DROUGHT SEVERITY for the first six-month of 2002 show that the most severity of different droughts have been occurred in Gonabad with relative severity of 47. Therefore, this event requires 12.9% of credits relatively, with first order of preferences. Whereas, Bojnord city is with the least relative severity drought of 4, and the last credit paying preference, has relatively received 1.1% of province total credits.
