General Assemblies

The overarching goal of IUGG General Assemblies is to link the various geoscience communities, enhance the visibility and the capacities of early-career geoscientists, and foster future collaboration in geoscience worldwide. General Assemblies also presents a forum to discuss the Union’s activities and decide on its future scientific program.

IUGG General Assemblies

  • are open scientific assemblies with several thousand participants and scientific sessions of our eight International Associations, interdisciplinary joint symposia, Union Symposia, Union Lectures, and various side events with workshops, meetings,
  • serve as a platform for young academics to exchange, present themselves, build professional networks, and discuss upcoming scientific developments within different thematic forums.
  • bring together the delegates of the 74 IUGG member countries with the members of the IUGG Executive Committee to discuss the activities of the last term and to further develop the Union and the eight International Associations with their scientific programs, and
  • host business meetings of the Union, the Associations, and its sub-entities.

The next General Assembly will be held in Incheon (Rep. of Korea) in 2027.
