The International Consortium on Geo-disaster Reduction (ICGdR) is delighted to announce the first ICGdR World Congress will be held in Hong Kong, China, from August 9 to 12, 2026. As a flagship international event of ICGdR and UNESCO Chair on Geoenvironmental Disaster Reduction, the World Congress will be convened every four years, providing a premier platform for global experts, researchers, and practitioners to exchange knowledge and advance the field of geo-disaster reduction. The theme of the First ICGdR World Congress, “Geo-disaster Reduction in the Era of Climate Change and Artificial Intelligence”, reflects the urgent need to address the increasing challenges posed by climate change, while leveraging the transformative potential of artificial intelligence in disaster risk reduction. The Congress is committed to upholding the highest standards of scientific quality, fostering global participation, and promoting inclusivity and sustainability. The 2026 Congress will feature 14 parallel sessions, mainly organized by ICGdR technical committees, each focusing on a distinct topic within the broad field of geo-disaster reduction, along with 1 student session and 1 poster session. We warmly invite active researchers and leading engineers to join us in Hong Kong for this landmark event, to share your insights, collaborate with international peers, and contribute to building a safer and more resilient world.
