Interested contributors have until 30 January 2023 to submit abstracts for the IAEA’s International Symposium on Isotope Hydrology: Sustainable Water Resources in a Changing World, to be held from 3 to 7 July at IAEA headquarters in Vienna, Austria.
Isotope hydrology is a sophisticated nuclear technique that reveals the history of water molecules and contributes to a better understanding of the way in which water is cycled through land, the ocean and the atmosphere, known as the water cycle. It has applications in water resources assessment and management, the study of past and future changes in the Earth’s climate and the impacts of climate changes on the water cycle, and in forensic areas such as ecological, wildlife and food source traceability.
Held every four years since 1963, this 16th symposium in the series will provide a unique opportunity to review the state-of-the-science, practical applications, research trends and needs in isotope hydrology. Building on the success of the past six decades, the event will bring together water and environment professionals from developed and developing countries to facilitate the exchange of information and knowledge.
“Technical capacity development is central to achieving the United Nations’ Sustainable Development Goal – SDG 6 – on ‘clean water and sanitation’,” said Najat Mokhtar, IAEA Deputy Director General and Head of the Department of Nuclear Sciences and Applications. Highlighting that in the last 10 years the IAEA has carried out over 125 projects in 75 countries specifically in improving the technical capacity to analyse water samples in well-functioning laboratories, she added: “In all these projects, we tailor our services to the local needs, with a significant capacity building component. In island states, we help nations tackle saltwater intrusion. In the Central American Dry Corridor or in Africa’s Sahel regions, we help countries address transboundary groundwater management.”
Contributors interested in submitting papers for the Symposium should focus on the following topics:
Revisiting the role of tritium as a tracer in hydrological cycle processes and groundwater systems
Hydrosphere–atmosphere interactions including isotopic insights on meteorological extremes, convective rains and catchment runoff
Assessing changes in the cryosphere and their impact on water sustainability and security
Evaluating water quality, tracking contaminant sources and reaction pathways in different environmental systems including areas affected by mining and agricultural activities
Application of isotope age tracers to evaluate sub-annual to 1 Ma water residence time
New analytical developments, approaches, and tools in isotopologue ratio measurement and data quality
Integrating isotope techniques with other advanced techniques such as big data from remote sensing or high-frequency sensors, advanced data analysis using geographic information systems, machine learning and/or modelling applications
Isotopic reflections on water resources due to climate change including adaptation and mitigation approaches
Enabling and strengthening science-based policies for water resource management
Actions and activities that support capacity building and mainstreaming of gender equality in isotope hydrology projects
The event will take place in between the UN Water Conference in March and the UN Climate Change Conference (COP28) in December. “Technical conclusions and findings of our symposium will help identify high priority activities for the IAEA Water Resources Programme,” said Jodie Miller, Scientific Secretary of the Symposium and Head of the IAEA’s Isotope Hydrology Section. “Our activities will feed into the 2018 to 2028 UN Water Action Decade and make tangible advances towards achieving SDG 6.”
Guidelines for the submission of abstracts are available here. Attendance at the conference is free of charge and there is no registration fee.
IAEA and six decades of water science
The IAEA promotes the application of nuclear techniques to all aspects of freshwater resource assessments and water management and protection. It provides training in isotope hydrology data analysis and measurement methods, as well as expert services and analyses. The IAEA also supports capacity building and technology transfer through technical cooperation projects as well as coordinated research projects and organizes training courses, fellowships, expert missions, webinars and international conferences to support the continuous professional development.
In support of these actions, the IAEA houses one of the world’s leading laboratories in isotope hydrology at its headquarters in Vienna, Austria. Covering liquid water, water vapour and the cryosphere, this lab generates and curates data on the isotope composition of water in precipitation, surface-water and groundwater. The data generated here, and other labs that the IAEA supports, provides the necessary information for countries to develop a comprehensive evaluation of the status of national water resources.
The IAEA and the World Meteorological Organization (WMO) have been operating the Global Network of Isotopes in Precipitation (GNIP) since 1960, a worldwide isotope monitoring network of hydrogen and oxygen isotopes in precipitation, in cooperation with partner institutions in over 100 Member States.
Similarly, the Global Network of Isotopes in Rivers (GNIR) is a worldwide voluntary environmental observation programme initiated in 2002 dedicated to the collection, compilation and dissemination of isotopic assays of Earth’s river waters.
