Passing of Malin Falkenmark

It is with great sadness that we have learned of the passing of Professor Malin Falkenmark. She is best known for her long-standing work and expertise on the sustainable use of water resources to meet human and ecosystem needs. Her work is characterized by pioneering integration of both natural- and social-science approaches in global perspectives. She is particularly known for developing the Falkenmark Water Stress Indicator, concepts of Blue and Green water and Comparative hydrology.

She has had a long relationship with IAHS including receiving the IAHS-UNESCO-WMO International Hydrology Prize in 1998 https://iahs.info/About-IAHS/Competition--Events/International-Hydrology-Prize/International-Hydrology-Prize-Winners/MFalkenmark/. In 2022, inspired by her teaching and long contribution to our sector,  IAHS launched a new award in her honour aimed at the best PhD thesis from a financially disadvantaged country https://iahs.info/About-IAHS/Competition--Events/Falkenmark-Award/.

The Stockholm Resilience Centre have written an obituary providing much more information https://www.stockholmresilience.org/news--events/general-news/2023-12-06-malin-falkenmark-water-pioneer-and-academic-mother-of-water-research-has-passed.html.

Congratulations to the HELPING Theme Leaders!

Three Theme Leaders are selected to lead the clusters of Working Groups during the initial period of the Science for Solutions decade HELPING. Currently, HELPING has consolidated into 25 Working Groups with 6-140 participants each (42 on average) to which members can still sign up.

The IAHS management team has now evaluated the candidates who applied as Theme Leaders, who will help organise the new Science for Solutions decade HELPING. We are happy and grateful to announce the following volunteers who will serve the IAHS community in leading this initial phase of the decade.

Theme 1: “HELPING with global to local interactions” (14 Working Groups)

Prof. Justin Sheffield; Head of the School of Geography and Environmental Science at the University of Southampton, UK.
Justin has more than 30 years of experience in research, applications, and leadership across a diversity of hydrological topics, from fundamental understanding of processes, including under climate change, water resources assessment and management, and the science and applications of the water-energy-food nexus. He has carried out this research at global, regional and local scale, including working directly with communities, and has worked on understanding scaling issues, cross-scale interactions and data representation that would be relevant to this theme. He has extensive experience in working with, generating, and disseminating data and models across these scales.

Moreover, he has substantial experience in dealing with capacity development and co-creation with people in financially disadvantaged countries. He has developed networks of researchers and practitioners to provide opportunities for collaboration, employment and learning beyond the lifetime of single projects.

Justin Sheffield - University of Southampton

"In this position, I will leverage my experience to lead the theme over the next 2 years such that it develops into a vibrant and active programme, and is in a good position for the next 2 years under the following theme leader. Moreover, I will apply as flat a management structure as possible, to provide early career researchers experience in leadership", says Prof. Justin Sheffield. 

Theme 2: “HELPING with holistic solutions for water security” (8 Working Groups)

Dr Ana Mijic; Director of the Centre for Systems Engineering and Innovation & Reader in Water Systems Integration at Imperial College, London, UK.
Ana is leading and supporting a broad and interdisciplinary research group, working across multiple aspects of water systems integration and systems modelling. She is a lead author for the “Coevolution and Prediction of Coupled Human-Water Systems: A Synthesis of Change in Hydrology and Society” in the IAHS Panta Rhei Synthesis Book that will be published in 2023.

Ana applies systems approaches to water management, and has been working on novel methods and tools for integration and coordination of interventions for both managing the high and low flows and water quality. Ana has been conducting academic research for ten years and has been involved in water management research in the UK, India, South Africa and Malaysia, among others. She has worked on the integration of water and energy systems, water and planning systems as well as Nature-Based Solutions.

Ana Mijic - Imperial College, London

"As a Theme Leader, I will create a shared perspective based on the topics of individual Working Groups (WG). This will enable the WG leaders to see their role within the theme, but also to find other WG that they would potentially like to collaborate with”, says Dr Ana Mijic, and continues: “I will make sure that there is a process how to communicate findings from the Working Groups, not only by them reporting to the Theme Leader, but also by creating forums where groups can communicate between themselves, particularly if topics of their research are complementary. As such, I will help shaping the narrative and integrating findings from Theme 2 WGs."

Theme 3: “Theme 3 HELPING with cross-cutting goals” (3 Working Groups)

Dr. Adeyemi Olusola; Assistant Professor, York University, Canada.
Adeyemi is a physical geographer by training who has worked across diverse geographical contexts from Nigeria to South Africa, and now in Canada. This unique perspective enables him to comprehend water-related issues through a global lens, bridging the divide between the Global North and South. Adeyemi is experienced in analysing extreme events, using trend analysis, climate model data and remote sensing. Recently he has also engaged in indigenous people’s perception of rivers. His history with IAHS includes participating in UPH and STAHY meetings.

Theme 3 is a bit different to the other two Themes as it is more focused on support than on science and, moreover, this theme is small with only three WGs. However, these WGs are important in boosting the other Themes and contributing with policy aspects, science communication and co-creation approaches for engaging with local people.

Adeyemi Olusola - York University, Canada

"My unwavering passion for all aspects of water, including its intricate issues, security challenges, and extreme conditions, drives my aspiration to contribute significantly to this crucial cause of HELPING", says Dr. Adeyemi Olusola, and continues: “I bring patience, trustworthiness, and an unwavering commitment to the principles of equity, diversity, and inclusivity. I am steadfast in my belief that regardless of race, gender, colour, or beliefs, fostering an environment of inclusivity is paramount. I am committed to creating spaces within my leadership where vibrant working groups and clusters can thrive, enabling open and productive discussions.”

Obituary Mervyn Peart

It is with great sadness that we report the unexpected passing of Mervyn Peart on September 15th 2023 at his home in Scotland, two weeks short of his 69th birthday. Mervyn will be known to many longer-term ICCE members, since he was a regular participant in ICCE Symposia and Workshops over a period of nearly 30 years extending from the mid-1980s (Albuquerque, USA) through to 2012 (Banff, Canada and Chengdu, China). As such he must rank as one of the most prolific ICCE members in attending its meetings and contributing papers to the associated ‘Red Books’.

Open Call for Co-Editors for the IAHS Digital Water Globe

Engage and take lead of this new digital innovation connecting IAHS members! 

The Digital Water Globe is open for everyone to easily explore and find recent advances in hydrological sciences. The tool gives visibility to both published and unpublished findings, as long as it is evidence-based. It can hold action-oriented key-messages to stakeholders, as well as scientific synthesis on specific processes in the hydrosphere. It is a common ground to share and search scientific information, using site location or keywords.


The digital revolution is accelerating and the past pandemic induced both constraints and innovations. To coincide with the IAHS centenary in 2022, the IAHS Bureau decided to develop a digital water globe (DWG), which aimed to stimulate and facilitate engagement, interactions, and dialogues between IAHS scientists and stakeholders, such as other experts, practitioners, media, and citizens. The development uses state-of-the-art technology in web visualisation to share cutting-edge hydrological research in case studies and datasets from all IAHS members as well as IAHS scientific publications.  

The DWG enables

  • Global graphical display of case studies, people, publications and data.
  • Search and find functions for targeted scientific achievements (based on keywords and filtering).
  • Opportunity for visibility and scientific outreach.
  • Ability to link research groups and foster scientific collaboration.
  • Framework for displaying and linking projects contributing to IAHS Commissions and Initiatives (e.g. UPH, Committees, Working Groups, and Scientific decades - PUB, Panta Rhei, HELPING).
  • Evolution and innovation over time to provide an on-going platform and archive.


To ensure DWG progress for continuous successful user uptake and impact, we are looking to appoint two DWG Co-Editors who will be supported by a team of Associate Editors and a Steering group. The DWG Co-Editors will be appointed for two years initially and are responsible for:

  • Promoting the DWG within IAHS and to other water stakeholders.
  • Attracting content to the DWG.
  • Guiding the DWG Associate Editors.
  • Reporting annually on the DWG to IAHS Bureau and the DWG Steering Group.

To be considered as a potential DWG Co-Editor, please complete this Google Form (now closed) before 17 November 2023. If you cannot access the online Google form, please contact the IAHS office on [email protected]. Each applicant will be contacted directly via email by the IAHS office and the following documents will be requested:

  • A covering letter no longer than 1 page, including the names and email addresses of two contactable referees. 
  • A resume no longer than 2 pages.

Once all applications have been received, the call will be closed and the IAHS management team will evaluate the applications based on documented leadership skills, scientific knowledge in the field, experience in community management, and personal engagement / qualities. The appointments will be announced in December.

Good luck!

HELPING Working Group workshops on 2 & 9 November 2023

The vision and scope of the Science for Solution decade is now crystallising after intense engagement within the IAHS community during this first year. You can follow the progress of the strategic planning (here). The next step is to kick-off the working groups to get into action!

Thank you to everyone who has signed up to the Working Groups for the Science for Solutions HELPING decade. Applications are still being received – go to https://iahs.info/Initiatives/Topic-for-the-Next-IAHS-decade/helping-working-groups/ and sign up to the working group of your choice via the website link (or contact the IAHS secretariat for assistance if you cannot access Google forms).

Currently, we are encouraging the Working Group leaders to be in touch with the people who have already signed up to their Working Group this month, to further iterate on scope and organisation of the collaborative work they foresee.

To share these actions with the full HELPING community, there will be two online meetings Thursday 2 and 9 November (at 13-16 CET). We expect 3-hr meetings where each working group leader (or another appointed person) present their idea for 2 minutes (max 2 ppt slides) followed by comments and questions from the audience. The presentations will be organised in the Themes and follow the structure of already identified goals (see here: https://iahs.info/Initiatives/Topic-for-the-Next-IAHS-decade/helping-working-groups/). Thereafter, time will be given for each Working Group to elaborate a more detailed workplan in parallel discussions (separate break-out in virtual rooms). 

A poll link will be shared via the Working Group leaders soon and a Zoom link will be shared via the Working Group leaders later this month. Note the two days are the same so you can attend one or both.

AGENDA for both 2 and 9 November 

13.00 – 13.10 CET Introduction to the Science for Solution decade HELPING - content and procedures (Berit Arheimer)

13.10 - 13.40 CET Theme 1: HELPING with global and local interactions (“2 min of madness”-presentations)

13.40 – 13.55 CET Open discussion on Theme 1 focus and goals

13.55 – 14.00 CET Sanity break

14.00 – 14.25 CET Theme 2: HELPING with holistic solutions for water security (“2 min of madness”-presentations)

14.25 – 14.40 CET Open discussion on Theme 2 focus and goals

15.15 – 15.45 CET Discussion in break-out groups for each WG (split audience into parallel rooms)

15.45 – 16.00 CET Reunion in plenary for feedback and open discussion on way forward.

Note that it is up to each working group to agree on activities, deliverables, and time-plan with participants. Some working groups may have a very specific aim and last for short time – while others may be more general and evolve over the full decade, using a living planning process.

Moreover, we have started to formulate an opinion paper to launch the vision of the Science for Solution decade HELPING in HSJ.

Looking forward to seeing you soon online!
