Date palm ('Phoenix dactylifera' L.) is a valuable plant that provides a significant source of income for both local farmers and governments in arid and semi-arid regions of the world. Modelling approaches that can map this economically important species accurately and its likely future distribution should be useful for the formulation of more effective, long-term management plans. The main objective of this study was to determine how climate change may impact on the future distribution of date palms worldwide and in Iran. This research constitutes studies based on different modelling techniques that should contribute to better mapping and projected distribution of date palm in an era of climate alteration.
