Advancing Eurasia Fire Understanding Through Machine Learning Techniques (2502.17023v1)

Abstract: Modern fire management systems increasingly rely on satellite data and weather forecasting; however, access to comprehensive datasets remains limited due to proprietary restrictions. Despite the ecological significance of wildfires, large-scale, multi-regional research is constrained by data scarcity. Russian diverse ecosystems play a crucial role in shaping Eurasian fire dynamics, yet they remain underexplored. This study addresses existing gaps by introducing an open-access dataset that captures detailed fire incidents alongside corresponding meteorological conditions. We present one of the most extensive datasets available for wildfire analysis in Russia, covering 13 consecutive months of observations. Leveraging machine learning techniques, we conduct exploratory data analysis and develop predictive models to identify key fire behavior patterns across different fire categories and ecosystems. Our results highlight the critical influence of environmental factor patterns on fire occurrence and spread behavior. By improving the understanding of wildfire dynamics in Eurasia, this work contributes to more effective, data-driven approaches for proactive fire management in the face of evolving environmental conditions.

Russia's vast ecosystems, from dense forests to tundra, significantly influence Eurasian fire dynamics, necessitating comprehensive studies. The complexity introduced by factors such as climate variability, anthropogenic activities, and vegetation diversity requires innovative data-driven approaches beyond traditional empirical models.

Literature Review

The evolution of fire prediction modeling has progressed from simplistic statistical methods to intricate machine learning techniques. Early methodologies, relying on logistic regression and linear models, often failed to encapsulate the complex, non-linear interactions governing fire behavior. Subsequent advancements with ensemble methods like Random Forests and gradient boosting demonstrated improved performance in processing rich, high-dimensional datasets and producing interpretable feature importance rankings. These methods have effectively captured the intricate relationships between environmental variables and fire incidents.

The emergence of deep learning marked a pivotal shift, particularly in using CNNs for spatial analysis of satellite imagery and LSTM networks for temporal dependency modeling. Furthermore, hybrid approaches integrating Graph Neural Networks and attention mechanisms have excelled in simultaneously capturing spatial and temporal fire dynamics.

Contemporary research focuses on real-time prediction capabilities, driven by edge computing and multi-source data integration, enabling agile responses to fire events. The field continues to evolve with explorations into explainable AI, transfer learning, and multimodal data fusion to enhance interpretative clarity and predictive accuracy in complex ecological systems.

Methodology

Dataset Overview

The paper presents the FiresRu dataset, a comprehensive compilation of wildfire events and associated meteorological conditions across Russia. Spanning 13 months, it encompasses diverse fire types: natural fires, forest fires, controlled burns, uncontrolled burns, and peat fires. This dataset, characterized by significant geographical and climatic variability, provides an invaluable resource for analyzing fire-ecology relationships.

Data Analysis

Analyzing the dataset reveals distinct environmental patterns associated with different fire types. Temperature and solar radiation notably influence fire occurrence, highlighting their roles in altering fuel moisture and creating favorable ignition conditions. The dataset's class imbalance, evident in the predominance of forest fires, poses challenges commonly addressed through advanced machine learning techniques.
