PRESIDENT’S FORUM Dear IAMG Members, for the Government of the state in which I live. We This is my first letter as President of IAMG and, on have four meetings a year to which we invite a scientist behalf of the new Council, my first duty is to thank to make a presentation to politicians on a specific Jennifer McKinley and the members of the previous policy-related topic with the expectation that it might Council for the work they have done over the past four inform policy. Some of these meetings have focussed years and for the very strong and healthy state in which on matters directly relevant to the mathematical they have left the IAMG. My second duty is to thank the geosciences. There are similar initiatives in other chairs and members of the various Council committees states in Australia and in other counties. It is somewhat for their significant contributions to the operation of the more difficult to do this on the global scale of IAMG, IAMG during the tenure of the previous Council. but perhaps we could exchange views and strategies on how this might be fostered at the local or regional Your new Council was formally installed area. It would be particularly useful to on 1st September 2020. Some of us, hear from IAMG members who have been including me, are new to the Council and involved in successfully informing policy its committees and we are in the process and/or in successfully contributing to the of familiarising ourselves with the structure public understanding of science relevant and operation of the IAMG. to policy. As a priority, I want to ensure as wide a Through the IAMG Council we could participation as possible in IAMG activities consider ways to increase collaboration in terms of regions/countries, gender, with various agencies and to advance the diversity and disciplines and I would mathematical geosciences as a resource welcome suggestions from members on that can inform policy decisions on natural how we could promote and achieve this resources and the environment as well as aim. As a start, we called for expressions of interest in promoting the individual disciplines that chairing the various IAMG committees for the tenure comprise the mathematical geosciences. There are of the new Council. Thank you to those members who several industry areas relevant to the mathematical responded to this call.

The mission of the IAMG is to promote, worldwide, the advancement of mathematics, statistics and Several members have made suggestions for virtual informatics in the Geosciences. We are also committed conferences and other forms of communication and to promoting diversity, inclusion, fairness, impartiality dissemination. In my own field, I have found short and democracy.

In my view we cover the first four of these reasonably well. The fifth role is a means of I look forward to the next four years as your President contributing knowledge and reason to decision-making and, together with your Council, I welcome your input and to the formulation of policy.
