Land suitability analysis is an important step in agricultural land-use planning and plays an important role in identifyng areas with the highest levels of suitability for crop cultivation, allocating them appropriately, and reduce adverse environmental impacts. Since more than 10% of the world’s dates are produced in Iran a crop with significant foreign exchange earnings the government has, in recent years, pursued plans to expand the cultivation area of date palms in regions suitable for its production. The Jiroft Plain holds a significant share of date production in the country; therefore, this study evaluated the land suitability of the Jiroft Plain for date cultivation using a combination of two multivariate decision-making methods and a geographic information system under current conditions and groundwater change scenarios projected for the year 2031 (1410 in the Iranian calendar), an aspect that has received little attentionin land suitability studies. The results showed that the Jiroft Plain has minimal climatic limitations for date production; however, there are constraints related to water and soil factors, which vary across different parts of the plain. the results of the pairwise comparison of the 13 factors considered for date cultivation indicated that parameters related to topography and water resources were more important than the other factors. Based on the findings, most areas of the Jiroft Plain classified as “moderately suitable” for date cultivation, and under pessimistic groundwater scenarios within the next decade, most lands are expected to decline to a “critically suitable” category. The study also revealed that to enhance productivity and improve land management, policymakers and farmers must give serious considerationto the limitations of water resources when selecting sites for the expansion of date palm orchards in the Jiroft Plain. The maps generated by this studyan provide a basis for planning and developingdate palm plantations in the study area.
