The aim of this study was to evaluate the accuracy of the climate suitability map of pistachio planting in the northwestern provinces of the country. Accordingly, the climate suitability map of pistachio planting was prepared based on long-term meteorological data using weighted overlap modeling in GIS environment. The accuracy of the mentioned map was evaluated by comparing it with the pistachio orchards map that located in this area using the Receiver Operating Curve (ROC). The results showed that 33, 33.4, 60 and 12.4% of the study area in East and West Azerbaijan, Kurdistan, and Ardabil provinces are suitable for pistachio cultivation respectively. The area under the curve (AUC) for the mentioned provinces were calculated as 0.9, 0.8, 0.9, and 0.62, respectively, which in general indicates the high accuracy of the results. In Ardabil province, insufficient attention to the limitation of high relative humidity in different stages of pollination, and fruit growth in the construction of pistachio orchards has caused a low area AUC. Citing the results of the climate suitability of pistachio cultivation map can be a good guide for site selection of new orchards and therefore, the reduction of crop yield due to climatic hazards will be minimized.

Life Cycle Assessment method is an accepted approach for assessing the environmental impacts of a product's life cycle, which is calculated on the basis of two components: the amount of consuming resources and the release of pollutants to the environment. In this study, the environmental impact assessment of pistachio production from the beginning of planting to the field door was estimated using Life Cycle Assessment (LCA) method in Rafsanjan. Initial data were collected through questionnaire method and interview with local farmers. The collected data were analyzed using Ecoinvent®3.0 database and Simapro8.0.4.30 software. The system boundary, field and work unit were considered as a ton of pistachios in this study. The results of this study showed that the use of diesel and electricity as energy sources lead to the release of CO2, NOx, SOx and heavy metals into the environment. Analysis of the pistachio data showed that emissions from fertilizers in the layers had the highest role in source reduction, global warming, toxicity to humans, toxicity to marine aquatics and chemical photooxidation. Emissions from fuel consumption had the greatest effect on ozone layer depletion.
