| Popis: | In this study, the influence of climate change on land suitability for coffee cultivation in the Ecuadorian Amazon (EA) was investigated using five global circulation models (GCMs) in two different socioeconomic pathways (SSP126 and SSP585). Eleven physioedaphological factors were selected for the analysis and were combined with the most influential bioclimatic variables to model past, present and future suitable areas in five provinces of the EA. In assessing past suitability areas, key determinants varied based on land suitability levels. High suitability areas were primarily influenced by factors such as texture, organic matter content, soil fertility, soil depth, slope, and aspect, while pH, salinity, toxicity, drainage, and stoniness were more associated with moderate suitability areas. The present high suitability areas were influenced by texture, organic matter content, soil fertility, soil depth, and slope, whereas aspect, pH, salinity, toxicity, drainage, and stoniness were more prominent in modeling moderate areas. The ensemble estimation model projected distinct future scenarios for coffee cultivation; under the worst climate scenario (SSP585), Zamora Chinchipe and Morona Santiago, particularly in the east, face considerable unsuitability. Conversely, the more favorable scenario (SSP126) indicates high suitability across Pastaza, Orellana, and Sucumbios, with limited suitability in border areas adjacent to the Highland region. This study highlights the importance of implementing timely adaptation strategies to improve resilience to climate change impacts in the coffee sector. |
