Abstract
Uncertainty is a critical factor in assessing both climatic risks and the effectiveness of different agricultural policy strategies. Each climatic risk is identified by its own natural characteristics, including geographical area, time of occurrence and its severity. This study was performed in order to estimate potential risk of rain fed chickpea production at Kurdistan Province. Historical climatic data was accumulated from 15 stations and period of 1991-2012. Climatic parameter included: daily rainfall, daily temperature, daily humidity, daily sunshine and evaporation. Agro climatic indices which estimated in this study were period length of each chickpea phonological phase, physiological days and risk of optimum temperature and rainfall occurrences in each phase. Results of spatial and temporal analysis of agro climatic indices were determined suitable region and the amount of rained chickpea production. Kurdistan province was divided into three agro-climatic zones: high-risk zone or low agro-climatic suitability (0.23 % of total region), mediocre-risk zone or mediocre agro-climatic suitability (59.71 % of total region) and low-risk zone or high agro-climatic suitability (37.96 % of total region). The approach which used in this study suggested a new approach for estimating of beginning, end and length of growing period based on physiological days. The accuracy of this approach is very high and applicable for spatial- temporal analysis at regional scale in other semiarid regions.
