IAH Members' Alert - June 2021

Dear Colleague,

This edition of our Members’ Alert coms to you slightly later than usual, as we wanted to check the latest information from our congress organising committees in Brazil and Belgium. Both congresses have now received around 450 abstracts each, which is really good news. The scientific committees are busy preparing their programmes and will publish details shortly, so keep an eye on the congress websites for developments on this and further news on how to participate.

As promised in our last members' alert, the organising committees for both our congresses are preparing a joint declaration on groundwater. They would like your views on what are the most important issues facing groundwater now and in the future. The call is below - we've already received a good number of responses thanks to social media, but we'd like to receive even more!

A reminder too about our offers of free registrations for IAH members - via prize draws and also online application process.

This alert includes our final call for nominations for the posts of Vice President Programme and Science Coordination and Vice President for Asia Region, for members who would like to follow in the footsteps of Ralf Klingbeil and Devinder Chadha. Nominations should reach us by 16 June 2021 and elections are scheduled to take place from the beginning of July.

Stay safe, stay well.

Joint Congresses’ Groundwater Declaration – What are your views?

2021 is an exceptional year for IAH. It is the year with two congresses: the 47th IAH Congress in São Paulo, Brazil in August and the 48th IAH Congress in Brussel, Belgium in September.

To mark the occasion, the IAH National Chapters in Brazil and Belgium, the IAH Council, ABAS, and ALHSUD want to launch a joint Groundwater Declaration spotlighting groundwater challenges in Brazil, Belgium and other countries worldwide, providing solutions for sustainable groundwater management and awareness.

The Declaration will be based on the input of IAH members and collaborators from a short survey which will take around 10-15 minutes to complete. The survey link is below.

We are looking forward to your input. Thank you!

Elections for Council Vacancies - nominations

Following our sad losses of Devinder Kumar Chadha, Vice President for Asia, and Ralf Klingbeil, Vice President for Science and Programme, we find ourselves with two vacancies on IAH Council. We will therefore be holding elections to fill these vacancies. We now call for nominations for these positions.

All members who have paid their IAH membership fees can stand for election and are entitled to vote. IAH Council has appointed the Executive Manager, Ian Davey, as the Returning Officer, who will supervise the election. Nominations for those who wish to stand for Council are requested by 16 June 2021.

For further information regarding the nomination process, see the link below.

Applied Hydrogeology Award - call for nominations

Who has made an outstanding contribution to the application of hydrogeology, supporting international development efforts?

We are pleased to call for nominations for the 2021 ‘Applied Hydrogeology Award’. This award aims to recognise those who have made an outstanding contribution to the application of hydrogeology, resulting in an increase in living standards in low and middle income countries. We would especially like to receive nominations for our many colleagues who have less opportunity to publish papers in scientific journals and whose work is perhaps less well-publicised but nonetheless essential.

A panel appointed by IAH Council will review the nominations and it is intended that the award will be presented in September at the 48th IAH Congress in Brussels, Belgium.

Any IAH member may nominate a candidate, but self-nominations will not be accepted. Candidates do not need to be members of IAH. Nominations should include:

  • An explanatory statement by the person submitting the nomination (up to 300 words);
  • A letter of recommendation by any other supporter (up to 300 words);
  • A brief career history of the candidate (up to 300 words);
  • A list of projects the candidate has carried out, including aims, region and period of time;
  • A list of projects (planned or accepted), patents, publications or equivalent information.
  • And finally, if you had just 1 minute to persuade the panel why your nominee deserves the award, tell us what you would say, using not more than 100 words!

Your proposal must be in total be no longer than 5 pages of text in a single pdf-file. This should preferably be in English. Although we are happy to accept nominations in other languages such as Spanish, French, German, Chinese or Arabic, the judging will be based on an English version (translation will be arranged by IAH’s Secretariat). It should reach the IAH Secretariat by e-mail ( before July 1st 2021.

We look forward to receiving nominations from all our IAH Regions, to reflect the work of applied hydrogeologists across the world.

Inspiring Groundwater


As a result of the evolution of the pandemic and the vaccination status in Belgium and beyond in many locations, the IAH2021 Organizing Committee and the IAH Executive are happy to announce that the 48th congress of the IAH will be a live, face-to-face event. All indicators are on green.

Thanks to the numerous high-quality abstracts we have received, it’s clear that the +/- 300 speakers who will be present in Brussels promise a fantastic congress.

After careful consideration, the Organizing Committee has decided not to provide live streaming of the congress, but we are not forgetting all those among you who will unfortunately not be able to travel to Belgium in September: we’ll have an alternative solution for whoever would like access to the content presented at the congress.

Of course, we will remain very attentive, in the coming weeks and months, to the evolution of the pandemic and to our government requirements for organising a Covid-proof IAH2021 congress.

So, if you are done with Zoom or Teams meetings and feel more than ready to meet and share ideas and outcomes with real people... perhaps with a nice Belgian beer in your hand... IAH2021 will be one of the first live congresses after a long time. Be part of this unique event - earlybird registration will be closing soon.

Members’ Book Draw

Win a copy of “International Law and Transboundary Aquifers” by Francesco Sindico

Thanks to Francesco Sindico (Reader, International Environmental Law and Director, Strathclyde Centre for Environmental Law and Governance) and Edward Elgar Publishing, we’ve a copy of “International Law and Transboundary Aquifers” to give away to a lucky IAH member in our latest book prize draw.

Groundwater amounts to 97% of available global freshwater resources. Emphasising the crucial importance of this in the context of increasing population, climate change and the overall global water crisis, Francesco Sindico offers a comprehensive study of the emerging body of international law applicable to transboundary aquifers.

Adopting a scenario-based approach, this much-needed book analyses a diverse set of transboundary aquifer agreements and arrangements. With just a handful of such agreements and arrangements around the world, it demonstrates how identifying a normative roadmap for countries that want to begin jointly managing a transboundary aquifer is of paramount importance. Offering an in-depth exploration into the ILC Draft Articles on the Law of Transboundary Aquifers, it provides insight into how this body of law is evolving, and discusses its relation to customary international law.

Academics and researchers interested in international water law, environmental law and public international law more widely will find this a unique and compelling work, whilst the book’s practical approach will also make it a useful tool for transboundary aquifer professionals and wider stakeholders working in governments and public bodies dealing with water management around the world.
