The inevitable effects of climate change in the agriculture sector are easily underestimated by agencies and stakeholders, having no means of quantifying them. For these effects to be accurately estimated, a system or method for calculation of the effects is needed. This paper addresses the problem through suitability modeling using GIS to evaluate the suitability of four primary crops like banana, coffee, pineapple and peanut using the relevant variables of slope, elevation, soil, land cover, rainfall, and temperature under RCP 4.5 scenario in municipalities of Amulung, Camalaniugan and Gonzaga, Cagayan, Philippines. It further investigated the suitability of the areas when hazards like flooding and landslide were considered. Results of suitability modeling revealed that pineapple is the most suitable followed by peanut, coffee, then banana. The final suitability maps generated showed that the suitable areas for production of the four different commodities changed greatly when the hazard component is included. Mitigation activities can be applied to increase the suitable areas for crop production. Adaptation through growing crops more resilient to climate change effects can also be undertaken.
