Abstract:

Drought is one of the most costly natural disasters in Iran and the need for a study to determine vulnerability and identify the factors affecting it in different parts of the country.The aim of this study was to compare CVI and AHP methods in assessing drought and measuring climatic vulnerability in Guilan province in order to identify its dimensions.The research method is spatial and applied in terms of purpose. In the AHP model, the importance of the resource component (R) with a weight of 0.293 is the highest and the weight of the component of geographical features (G) with a weight of 0.045 is the lowest. In the study of variables in the AHP model, the variable of total rainfall with a weight of 0.750 was the most effective variable and the variety and quality of agricultural products with a weight of 0.088 was the least effective variable according to experts. In the study of CVI components, the CVI index of the whole province was 44.5%. The CVI index had the highest rating in the resource component (R) at 56.12% and the lowest rating in the 36.94% component. The zoning of the AHP model showed that the middle part of the province, including Rasht, Saravan, Kasma, Anzali, has the highest area with an area of 42.11%. In the CVI model,the highest vulnerability is in the whole city of Talesh with an area of 15.57%.Astara and Rezvanshahr cities with an area of 20.88% were observed in a very low vulnerability class.
