Researchers have developed SAGE-XGBoost, a novel machine learning framework designed to improve natural hazard susceptibility mapping, particularly in data-scarce environments. This framework integrates spatially augmented graph embeddings with the XGBoost algorithm to enhance prediction accuracy. SAGE-XGBoost demonstrated significant improvements over existing models, achieving AUC values of approximately 0.97 for landslide susceptibility and 0.95 for wildfire susceptibility, while also enhancing spatial coherence and reducing noise.
