We are pleased to announce the inaugural Editor-in-chief for the Digital Water Globe (DWG): Prof. Eduardo Mario Mendiondo of the University of São Paulo - São Carlos School of Engineering. The DWG is a web-based software platform where IAHS members share Case studies, Personal profiles, IAHS references and links to data repositories. The different items are linked to a geographical position on a global map as well as keywords for quick search using filter functions. The DWG offers co-creation and re-examines the role of scientific outreach by exploring novel digital ways to interact between scientists and society for mutual understanding and co-evolution. Most of all, the DWG will exploit the potential of an innovative digital arena for IAHS-community building, data/knowledge exchange and science communication in action. We invite you to view and contribute to the DWG!
