We evaluated the impact of climate change on the displacement of areas suitable for potato cultivation through the land evaluation methodology of the FAO-supported software ALES, based on climate scenarios generated by two general circulation models, using layers of climate and soil data (WorldClim) and two climate change scenarios developed by the CSIRO and HadCM3 models with scenarios A2 and B2 of the IPCC, generated climate suitability maps and final suitability maps by classes and subclasses considering their limitations associated with risks related to pest and degraded soils, as with the actual economic viability of the Reventazon river watershed and a model of the change in the zones with potential for the cultivation of potatoes (Solanum tuberosum) for projected average climate between 2050- and 2080. Two suitability classes were determined: A3 (marginally suitable) and A4 (not suitable) and the economic viability by gross margin (GM), yield and total production in the productive zone. Actual GM of 1962 million colones and yield no greater than 23.98 t/ha and total production of 754 million t/ha. In both scenarios, the physically and economically suitable zones demonstrated changes in the reduction of their areas toward higher altitude, a medium to high risk of pest (T. solanivora, P. infestans) infestation and soil degradation was found. The suitability class most affected was A3 for both models. The yield is variable with the model HadCM3 and remains the same with CSIRO when compared to the actual scenario. Class A3 presents limitations for maximum and minimum temperature and precipitation, in addition to gradient and altitude. Modeling of suitability zones based on climate change generates information on the grades of sensitivity and permits the design of strategies for the mitigation and adaptation to climate change.
