2018, November 5 Australia-Japan Forum

Australia-Japan: Science and Technology Diplomacy and Public Policy

November 5, 2018 brought the Australia Now! symposium to the University of Tokyo, Hongo campus. This symposium was an opportunity for those in the fields of science and science communication to discuss innovative ideas about collaboration and how international partnerships are necessary to address global problems. Scientists from around the world stressed the importance of international science diplomacy as well as the merit of international partnerships.

Throughout the day there were many interesting panel discussions focused on topics related to collaboration and science diplomacy. The session after morning tea captured the attention of the audience with discussions about climate change, geohazards, and minisatellites. One of today’s challenges is assessing how different earth systems respond to climate change. Since climate change and its related effects is a global concern, international and cross discipline collaboration is a necessary endeavor. A related challenge is communicating advances in scientific understanding to governments and policy makers in an effective manner.

This panel also discussed the involvement of students in international partnerships. Recently, students from the Australian National University had the opportunity to travel to Japan for a geohazards excursion with students from the University of Tokyo. Students from both universities had a very positive reaction to the program and gained an appreciation for collaboration. Introducing young scientists to other scientists across borders, and realizing the benefits of such partnerships, is an invaluable experience – something which is never forgotten.

Though there are still many challenges related to international collaboration and science diplomacy, forums like the Australia-Japan symposium held at the University of Tokyo this week are essential for advancing ideas; possible science communication solutions; and building cross-border, cross-discipline relationships.
