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.
