This session explores how emerging AI and Big Data technologies are transforming the way we observe, analyze, and understand Earth systems. From deep learning models that extract patterns from massive remote-sensing datasets to real-time environmental analytics and geospatial data science workflows, the focus is on innovative methods that push the boundaries of traditional Earth observation. We will highlight applications such as smart remote sensing, AI-driven climate insights, and the development of Earth digital twins. The session invites young researchers to share fresh ideas, creative solutions, and forward-looking perspectives that will shape the next generation of Earth Science.

The aim of this session is to bring together the latest advances in hydrological science, artificial intelligence applications, and sustainable resource management to address the critical challenges of water availability and system dynamics. As global water cycles face unprecedented pressures from climate variability and anthropogenic demand, this session will showcase innovative applications - from AI-enhanced hydrological modelling and big data analytics to integrated water resource management (IWRM) strategies - and discuss how these tools can be deployed to solve practical catchment and resource management problems. We welcome contributions that span applied and operational hydrological studies, hydro-informatics, machine learning in hydrology, decision support systems, remote sensing, and water governance, with an emphasis on data-driven solutions that enhance resilience, inform policy, and support sustainable decision-making in complex hydrological systems.

Keywords: hydro-AI; applied hydrology; hydroinformatics; digital twins; decision support systems; water resources management

• Novel methods for characterizing geophysical hazards (e.g., earthquakes, tsunamis, volcanic eruptions, and mass movements)
• Multi-hazard approaches for geophysical and interacting hazards (e.g., multiple cascading geophysical hazards as well as interacting geophysical and non-geophysical hazards)
• Innovative methods for quantifying natural hazard impacts to people, built environment, and society as a whole
• Innovative and effective risk management approaches for natural hazards and their risks
• Insightful case studies that offer interdisciplinary perspectives from physical sciences and social sciences.

Research on Geoheritage, Geoparks, and Geotourism has experienced notable growth, highlighting their essential roles in advancing scientific understanding, supporting environmental conservation, and safeguarding cultural heritage. Investigating the significance of geological and geomorphological sites—as both records of Earth's history and vital resources for research—enhances our appreciation of these distinctive landscapes. Current research emphasizes the dynamic interface between natural environments and human societies, with a focus on promoting sustainable development and formulating strategies to bolster community resilience against natural hazards.

The intricate nature of abiotic environments is frequently underappreciated, particularly when juxtaposed with biodiversity, even though biological systems are fundamentally reliant on abiotic factors. This session aims to convene experts to discuss methodologies for characterizing and elucidating the relationships among abiotic components, biotic systems, and societal frameworks. Recent advancements in transdisciplinary studies of Earth's diversity have led to the emergence of comprehensive approaches—often termed "omnidiversity"—that expand our perspectives on environmental complexity. Contributions presenting scientific insights into these critical issues are welcome.

Human society exhibits considerable complexity, and although its interactions with abiotic features are evident, they remain inadequately understood, especially in light of rapid technological advancements such as artificial intelligence and virtual reality. Achieving a thorough understanding of societal perceptions toward abiotic nature demands analysis of social behaviors, structures, traditions, and their practical expressions. Evaluating aspects like sense of place or the cultural importance of culinary customs from a resource-based perspective necessitates a robust transdisciplinary methodology to foster sustainable collaboration with Earth’s resources.

Ongoing research into geoheritage and geodiversity plays a pivotal role in addressing pressing global challenges. This session provides an interdisciplinary platform to examine research questions, share strategies for conserving and managing geological features, and discuss best practices in geopark management and the evolving contributions of geotourism to sustainable development. We invite research contributions from around the world, particularly those incorporating advanced technologies such as geostatistics, geophysics, GIS, and big data analytics. Priority will be given to topics including geoethics in resource management, applications of artificial intelligence, and resilience frameworks.
