EGRISS has divided activities into four technical subgroups dedicated to complementary areas of work. The subgroups are focused on concrete tasks and deliverables and are established based on specific needs and demands. These are fluid and will not necessarily be functioning for the entire third mandate (2020-2024). The subgroups consist of identified EGRISS members and co-leads from countries and regional and international organizations. They count with an open and participatory approach to their membership, encouraging members to actively engage and contribute to their activities.
