Given the severe fluctuations in weather and decreasing rainfall, this study was conducted to identify suitable areas for rain-fed cultivation of orchard products in Kermanshah Province. In this research, using a spatial multi-criteria evaluation method and examining climatic factors (chilling accumulation, dormancy period temperature, absolute minimum and maximum temperature, relative humidity during the growth period, annual average temperature, degree-day of the growth period, annual precipitation, and sunshine hours) and topographic factors (elevation and slope), the potential area for cultivating of almonds, grapes, rose, figs, and olives on the province's sloping lands was assessed. Climatic parameters at each station were calculated based on 30 years of recent meteorological data (1993-2022) and were zoned for the entire province using the Co-Kriging method. The results show that rose, with 2 million ha of climatic suitability in the entire province and 810,000 ha on sloping lands, has the highest cultivation potential. After that, grapes, with about 640,000 ha of climatic suitability in the entire province and 191,000 ha on sloping lands, rank second. Almonds also have considerable potential for cultivation, with about 493,000 ha of climatic suitability in the entire province and 180,000 ha on sloping lands. Figs and olives, with 184,000 ha and 35,000 ha of climatic suitability in the entire province, respectively, have less potential than the previous trees. Overall, it can be concluded that a large part of the province's climate is suitable for the cultivation of fruit trees under rain-fed conditions.
