Special Session “Big Themes”:

For its 28th General Assembly 2023 in Berlin, IUGG has launched a new session format called “Big Themes”.

The relevant topics identified will be addressed in a condensed and novel format, with some quick introductions, a moderated panel discussion and an extended exchange with the plenary.

When: Daily from Thursday (13 July) to Tuesday (18 July), during the lunch break from 12:15 to 13:15 CEST
Where: Hall A3


BT#1 | Open Science, changing practices in science?

Thursday 13th, 12:15 – 13:15 – Hall A3

IUGG is committed to promoting digital science by supporting openly accessible and FAIR data, open software and thus open science. As a member organisation of the International Science Council (ISC), we are automatically signatories to the relevant declarations as well as supporters of the corresponding UN/UNESCO recommendation. The session will show the added value and perspectives for (Open) Science by means of selected examples.

Chairperson: Alexander Rudloff, IUGG

Wolfgang zu Castell | Chair, WG Open Science of Helmholtz Association & GFZ


BT#2 | Reflection of the International Year of Basic Sciences for Sustainable Development (IYBSSD)

Friday 14th, 12:15 – 13:15 – Hall A3

The International Year of Basic Sciences for Sustainable Development 2022 was a key moment of mobilisation to convince business and political leaders, as well as all citizens, of the importance of supporting, considering and mastering basic sciences to ensure a balanced, sustainable and inclusive development of the planet. IUGG is proud to support this global initiative proposed by the Republic of Honduras and proclaimed by the UN General Assembly.

BT#3 | Contribution to International Frameworks – Are we effective?

Saturday 15th, 12:15 – 13:15 – Hall A3

IUGG, its Associations and Union Commissions have successfully and sustainably contributed to many frameworks in the course of its hundred-year history, either directly or through scientific contributions. The Big Theme Session aims to address the importance of solution-oriented science.

This is a joint activity with the Global Geoscience Societies’ Task Team on “Advocate for the ESS in Global and Domestic Policies”

BT#4 | Early Career Scientists – Needs, Wishes and Demands!

Sunday 16th, 12:15 – 13:15 – Hall A3

Early Career Scientists (ECS) are the promising minds in academic science and will occupy the established research and teaching positions in the future, regardless of the discipline and association they belong to within IUGG. Each Association takes different approaches to bringing young scientists into leadership positions and promoting their work. This Big Theme aims to bring together ECS (and people with influence on ECS) from across IUGG to discuss how it can best support them and the feedback from the ECS social event.

Chairperson: Alexander Rudloff, IUGG

Co-chairperson: Hannah Rogers, University of Grenoble & IUGG-ECS coordinator

BT#5 | Where do we stand on EDI = Equality, Diversity, Inclusion?

Monday 17th, 12:15 – 13:15 – Hall A3

IUGG fully recognises the principles of EDI! However, as an international union based on country memberships, we face practical limits in implementation. Experiences and best practices will be shared and future strategies discussed.

This is a joint activity with the Global Geoscience Societies Task Team on Inclusion and Representation in Geoscience.

BT#6 | Strengthening the North-South Dialogue! What are the Needs and Challenges?

Tuesday 18th, 12:15 – 13:15 – Hall A3

IUGG and its associations are active worldwide, in line with the reach of geodetic and geophysical phenomena. Nevertheless, the participation of scientists, technicians and other stakeholders in the Global South is expandable. With the support of our partner institution, the ICTP, we want to focus more on this in the future and support new initiatives.
