#1. Foreword by Yukihiro Takahashi, President of JpGU

The 2023 Japan Geoscience Union (JpGU) meeting is over. Thanks to
all the participants, the second meeting as a hybrid was held without
any major problems, and the Makuhari Messe venue was very exciting.
Of course, we know that not everything was perfect and that there
are various issues to be improved, but first of all, we would like
to express our gratitude for having overcome a major event. I would
like to thank again all the participants, presenters, conveners, and
all those who helped plan and implement theme ting, especially the
meeting steering committee headed by Dr. Wada and the secretariat.
The number of papers presented increased 15% over last year to 4395,
recovering to 87% of 2019. The number of registered participants was
also up 16% to 7868, almost the same level as in 2019. Particularly
notable was the number of on-site participants, up 84% over last year
to 5802. While these numbers do not match the pre-COVID numbers,
which were in-person only, they are showing rapid growth. I don’t
think I am the only one who had the impression that the venue was
more lively than the number of people itself, since this was a
full-scale meeting after COVID. We received a variety of opinions
in the survey, which we will analyze and scrutinize in the future
in order to realize a more satisfactory meeting for the next year.

In the foreword of the Mailnews in May, I reported that exchanges
between academic societies were active during the period of the EGU
general assembly. The president and CEO of AGU, and the president of
CGU in Taiwan organized a delegation together with the secretariat
staffs to visit JpGU meeting. In addition, representatives of three
academic societies from Southeast Asia also visited JpGU meeting.
I feel that the recent international movement is not unrelated to the
background of such active international cooperation in geoscience.
I would like to earnestly face the role that geoscience can play as
an academic field for the future of the world.

(7) Announcement and survey request from Union Session

Thank you for your attendance for JpGU2023 U-07 session and the
Request from Conveners

Union Session U-07 “What is the true value of knowledge creation?
Our perceptions of science and society” (Conveners: Michiyo Shimamura,
Yuko Onishi, Brooks Hanson and Raj Pandya), conducted oral, e-poster
and on-site poster sessions on Friday May 26th, 2023 as planned.
We, conveners appreciate for your attendance!

The streaming of U-07 oral session is now available! Please watch
the video, if you missed it. Due to the streaming of U-07 session,
we extended the deadline of the questionnaire survey related to the
session as follows.

Closing date of this survey [extended]: Monday, July 31, 2023
U07 questionnaire in Japanese:
U07 questionnaire in English:

Please give us 10 minutes of your time! We would appreciate your
cooperation in filling out the questionnaire.

Details of the questionnaire survey:
In our previous session at JpGU 2022, U-04, a questionnaire survey
was conducted after the session to find out what exactly the members
of the JpGU community consider to be “responding to society’s mandate”
and what kind of activities they are actually engaged in to “respond
to society’s mandate”.

As a result, the following responses were obtained:
(1) more than 90% of the survey respondents answered that “connecting
science and society” is necessary, (2) researchers are the main actors
connecting science and society, but (3) the lack of resources (time
and costs) to “connect science and society” and proper evaluation on
scientific achievements are the issues.
The purpose of this survey is to find out how JpGU community members,
together with their stakeholders, are aware of the need to build a
more effective framework for “connecting science and society” and
how to connect these activities to the evaluation of scientific
performance. We will consider sharing the results of this survey with
those who cooperated with us at a later date.

@Shailendra Pratap & Yannis Markonis
The response of the hydrological cycle to temperature changes in
recent and distant climatic history.
This review assesses the relationship between past climate change
and the response of the hydrological cycle through a meta-analysis
of existing studies. The relationship between climate change and the
hydrological response is often simplified by the phrase ‘the rich get
richer’, particularly for the current anthropogenic warming, but it
is suggested to have complex spatio-temporal heterogeneity, at least
for the past.
