Abstract :
climate changes may cause severe droughts with heavy economic-social losses. Vulnerability assessment is the first step in the field of risk management and increasing the ability of farmers against drought. In this article, biophysical and socio-economic indicators (exposure, sensitivity and adaptive capacity) were used to measure vulnerability to drought risk. The results of the research showed that the trend of long-term changes in precipitation in all studied stations in Sistan and Baluchistan province is decreasing. The highest decrease was observed in Khash station and the lowest in Zahedan station. But among the revealed trends, only the rainfall trend of Zabul station was significant at the confidence level of 0.05. The results showed that the cities of Chabahar (2) and Khash (1.79) are more vulnerable to drought. In addition, this study showed that vulnerability to drought is related to social and economic development of the region. In general, regions with the highest level of exposure experienced the most vulnerability in the overall index. Also, regions with high adaptive capacity were not necessarily less sensitive to drought.
