How do we work?

We are organised as a bottom-up organisation, where the initiative for activities comes from individual scientists. We present ourselves as scientists, so we encourage supporters to use scientific function, titles and affiliations where useful. To realise impact, we are internally organised in so-called focus groups, which are listed below.

Focus groups

Each focus group consists of several participants of S4F-Twente. A focus group works largely independently, but with support of and under the flag of S4F-Twente and S4F-NL, and thereby adheres to the Community Principles. This is the current list (28-6-2021) of our focus groups:

  1. Fireside chats
  2. Core
  3. Policy
  4. Public lectures
  5. Behavioural change
  6. Schools

Each group focuses on a specific topic and formulates its own goals, forms its own organisation, and organises its own activities to achieve these goals. It is up to all members of the focus group to choose and define their own role(s), activities and tasks.

Each focus group supplies the core group with a notification and, when available, a copy of their ‘output’, for sharing within S4F-Twente. This serves (a) transparency about the S4F-Twente activities, (b) the potential wider use by other S4F-Twente focus groups/members, and (c) as a source of inspiration.

S4F wants every member to feel comfortable with the public activities of S4F. Therefore it is considered essential that for any public activity under the flag of S4F-NL and S4F-Twente each focus group/S4F-member organizes their own peer review/feedback about the planned public activity or publication. This can be done by seeking advice from others inside or outside the focus group, and possibly from experts. The core group may be able to help finding experts in specific fields. We encourage our participants to sign documents with their own names by default, and not in the name of S4F-Twente.

Fireside chat

Contact person: Prof. (emeritus) Theo van der Meer
The ‘fireside chats’ are informal conversations with other concerned scientists. We have a weekly meeting on Monday evening.


Contact persons: Evert Houwman, PhD and Erik Kemp, BSc
The core group of S4F-Twente organises and maintains a website as information, communication, and contact platform. It brings members with common interests together to form or join a focus group. Our contact form sends your message to this core group by default. We have a weekly meeting on Monday afternoon.


Contact person: Evert Houwman, PhD
This group focuses on climate-related policies. This can entail: working together with policy makers, to support them in realizing climate and sustainability action plans.

Public lectures

Contact person: Prof. Gertjan Koster
This group wants to list/(co)organize/advertise lectures (or other resources) for the general public, with topics that are related to ‘human impact on the environment’. We will build and maintain an internal knowledge ‘database’ on public lectures etc.

Behavioural change

Contact person: Prof. Alexey Voinov
We probably all agree here that human behaviour is one of the main drivers of environmental degradation today, including the climate disruptions that we are focusing on at this time. While we all know how difficult it is to change human behaviour, even our own behaviour, we also recognize that changing it can be the fastest and cheapest way to solve some of the problems we are facing. It does not take any resources for us to decide to eat less meat or change our vacation plans to spend some time on Schiermonnikoog instead of Bali. However, there is a big gap between knowing what has to be done and doing it. How do we bridge this gap? This is how I see the main goal of our focus group.


Contact person: Core group (temporarily)
This group will focus on organising and giving (a series of) guest lessons in secondary schools and ROCs, in cooperation with the teachers. Possible topics could be the physical, ecological, geographical, economical, historical, political, sociological, and health aspects of the climate emergency.
