Climate change and global warming have significantly impacted pistachio production in Iran, leading to a loss of 20-30% of some varieties and up to 50% in other areas due to extreme temperatures and irrigation interruptions. The article highlights the need for varying degrees of winter cold for different pistachio varieties, which has been reduced due to global warming. The Iranian Pistachio Association is considering solutions such as changing varieties and increasing irrigation, but water scarcity is becoming a major concern. The decision to plant pistachios or other crops is ultimately up to the farmer, but guidance on suitable crops for the climate and region is recommended.
