Thus, this study employed integrated machine learning and geospatial modeling (Random Forest, Support Vector Machine, XGBoost, and LightGBM) to predict current and future habitat suitability in Ethiopia under SSP2-4.5 and SSP5-8.5 (2041-2080), therefore promoting conservation and climate-resilient agriculture. Variable importance analysis revealed that agro-ecological zones were the most influential predictors, accounting for 14%-22% of the variance across models. Among bioclimatic factors, Bio19 (coldest quarter precipitation) emerged as a prominent driver (14.1% in RF; 10.3% in XGBoost), indicating the importance of dry-season water availability. Model performance varied: Random Forest had the best predictive precision (specificity = 0.93); however, XGBoost better identified spatial clustering patterns. Under present conditions, Random Forest predicted 30.02% of the study area as highly suitable, especially in the Western Highlands, whereas LightGBM predicted 18.62%, showing increased habitat fragmentation. Forecasts for the future (considering only climate and static topography) indicate a significant reduction in highly suitable habitats, with a 46.2% decline under SSP5-8.5 by the 2070s. Landscape-level measurements indicated increased fragmentation, including a reduction in Shannon diversity (1.48-1.29) and a 19.2% increase in fractal dimension, indicating more complex patch topology. These findings recommended the need to restore pollinator corridors in highland refugia, promoting drought-tolerant plants like Vachellia abyssinica, and integrating adaptive apiculture approaches.PMID:42306539 | PMC:PMC13265244 | DOI:10.1002/ece3.73842
