IAHS has proudly and successfully coordinated two Scientific Decades, which, amongst other things, set the research agenda worldwide through collaborative forces. The third Scientific Decade 2023–2032 of IAHS launches a topic for collaborative efforts in hydrological sciences: HELPING, created through a participatory community process and by applying strategic planning. The third IAHS Scientific Decade is dedicated to local solutions under the global water crisis. The name HELPING, stands for Hydrology Engaging Local People IN one Global world. The HELPING Theme and Working Groups are now available for you to view and join. If you're curious about the IAHS Scientific Decades and want to learn more, don't hesitate to get in touch with us. Our team is passionate about what we do, and we'd love to share the details with you. Just drop us an email at [email protected], and let's embark on this scientific journey together. Your quest for knowledge starts here!

The IAHS Digital Water Globe (DWG) is currently undergoing a major redevelopment and will be temporarily unavailable from the end of March 2026. This transformation marks the beginning of DWG 2.0 — a new and enhanced platform designed to strengthen how hydrological science is shared, explored, and connected across the world. The next generation of the DWG will build on the original vision while introducing new possibilities for visualising research, connecting scientific knowledge, and supporting the global hydrological community. During this period, the IAHS team is working behind the scenes to develop an improved platform that will better serve the IAHS membership. We look forward to sharing further updates as development progresses. Stay tuned as a new Digital Water Globe experience is coming soon.
