As we bid a heartfelt thank you to Prof. Berit Arheimer for her outstanding leadership over the past four years, we are pleased to officially welcome Prof. Salvatore Grimaldi as the new President of the International Association of Hydrological Sciences (IAHS). His term will run through to 2029.

Salvatore is based at the DIBAF Department, University of Tuscia, Italy, and brings a wealth of scientific experience, institutional insight, and an enthusiastic vision for the future of IAHS. He has been involved with the Association since as early as 2003, contributing to several key initiatives and roles — including the founding of STAHY Working Group (now known as International Commission of Statistical Hydrology ICSH), MOXXI Working Group and CANDHY Working Group.

His presidency begins at a time of renewed momentum for the Association, as we continue to advance the Science for Solutions Decade – HELPING and strengthen our global impact.

In the first months of his presidency, Salvatore has outlined several key priorities:

1. Supporting the Hydrological Sciences Journal (HSJ) as a central platform for the dissemination of cutting-edge hydrological research;
2. Developing new collaborative initiatives with the Intergovernmental Hydrological Programme (IHP) of UNESCO and World Meteorological Organization (WMO);
3. Promoting the new IAHS Scientific Assembly format, with a focus on enhancing both scientific quality and opportunities for networking;
4. Preparing a series of stakeholder-oriented community papers in support of the HELPING initiative;
5. Reinforcing the IAHS commitment to inclusivity and the active engagement of diverse scientific communities.

With his strong dedication to scientific excellence, international cooperation, and community building, Salvatore is ideally positioned to build on the solid foundation established by his predecessor and to guide IAHS into an exciting new chapter.

Please join us in extending a very warm welcome to Prof. Salvatore Grimaldi as he begins his tenure as IAHS President.
