The agricultural crops of Misamis Occidental are not exempted from the effects of climate change, hence, it is necessary to assess and map-out the key crop commodities in terms of their suitability in the future. Five major crops from the Philippine Statistics Authority (PSA) and from the Department of Agriculture (DA) were identified and validated by the community stakeholders. These are lowland rice, coconut, banana, cassava, yellow, and white corn. Crop vulnerability and suitability mapping were based on flood and landslide hazards prevalent in the area, biophysical factors together with baseline, and future agro-climatic data. The data were examined and simulated based on Multi-criteria Decision Analysis using Analytical Hierarchy Process in ArcGIS Software Version 10.8.1. Contemporary and future climate projections were derived from downscaled Global Climate Models GCMs and represented by 2050 time-period and two-emission scenarios as described in the 2007 Intergovernmental Panel for Climate Change. Representative Concentration Pathways 4.5 (medium case scenario) and 8.5 (worst case scenario). The simulation model indicates that these five major crops are not feasible in upland areas (RCP 8.5). However, the trend for corn and banana is moderately suitable in low-lying areas provided that the temperature is higher than the total crop requirement. Planting of cassava, coconut, and rice in low-lying areas has a moderate to high suitability under RCP 8.5. Overall, this study provides prediction on the status and conditions of crops which may adapt and are suitable in low-lying areas but not in upland areas in the future. However, these findings suggest that a thorough monitoring in the field must be done to ensure the crop suitability over the changes of weather pattern.
