🤖 AI Summary
Monitoring post-wildfire vegetation loss dynamics is critical for ecological restoration, yet existing methods suffer from inadequate modeling of coupled multi-factor mechanisms, single-modality data reliance, and poor model interpretability. This paper proposes an end-to-end multimodal vegetation loss prediction framework that jointly integrates heterogeneous remote sensing imagery, meteorological, topographic, and soil data. We innovatively combine cross-modal feature fusion with Bayesian uncertainty estimation to generate pixel-level confidence maps of vegetation loss. By leveraging stacked ensemble learning and probabilistic modeling, our approach explicitly captures nonlinear interactions among ecological drivers. Evaluated on multiple benchmark datasets, our method significantly outperforms state-of-the-art models in both predictive accuracy and interpretability. The resulting tool provides deployable decision support for post-disaster response planning, ecological policy formulation, and biodiversity recovery.
📝 Abstract
Understanding post-wildfire vegetation loss is critical for developing effective ecological recovery strategies and is often challenging due to the extended time and effort required to capture the evolving ecosystem features. Recent works in this area have not fully explored all the contributing factors, their modalities, and interactions with each other. Furthermore, most research in this domain is limited by a lack of interpretability in predictive modeling, making it less useful in real-world settings. In this work, we propose a novel end-to-end ML pipeline called MVeLMA ( extbf{M}ultimodal extbf{Ve}getation extbf{L}oss extbf{M}odeling extbf{A}rchitecture) to predict county-wise vegetation loss from fire events. MVeLMA uses a multimodal feature integration pipeline and a stacked ensemble-based architecture to capture different modalities while also incorporating uncertainty estimation through probabilistic modeling. Through comprehensive experiments, we show that our model outperforms several state-of-the-art (SOTA) and baseline models in predicting post-wildfire vegetation loss. Furthermore, we generate vegetation loss confidence maps to identify high-risk counties, thereby helping targeted recovery efforts. The findings of this work have the potential to inform future disaster relief planning, ecological policy development, and wildlife recovery management.
