Rice has been a staple food in Iran since the Sassanid era, with the northern provinces, especially Gilan and Mazandaran, being the main areas of cultivation. The country's rice production varies due to climatic conditions, water resources, and government policies, with Mazandaran being the leading rice-producing province. Despite being self-sufficient in rice production, Iran faces a shortage due to high domestic consumption and the need to import to meet demand, primarily from India and Pakistan. However, some Iranian rice varieties are exported to neighboring countries.
