9th Global Energy and Water EXchanges
Open Science Conference

Jul 7 - 12, 2024 | Sapporo, Japan

The implications of a shifting climate on our water and food resources demands an increased understanding of the intricate interplay between humans and the water, energy, and carbon processes, as well as of the dynamic transformations unfolding within them.

The 9th Global Energy and Water Exchanges (GEWEX) Open Science Conference, Water Climate, is organized under the auspices of the Global Energy and Water Exchanges (GEWEX) core project of the World Climate Research Programme together with Hokkaido University and Science Council of Japan. The conference will take place from 7 to 12 July 2024 at the Keio Plaza Hotel in Sapporo, Japan.

The conference will celebrate 30+ years of GEWEX research, the strong role of the Japanese research community and set the stage for the next phase of research addressing the World Climate Research Programme (WCRP) main challenges on water resources, extremes and climate sensitivity through observations and data sets, their analyses, process studies, model development and exploitation, applications, technology transfer to operational use, and research capacity development and training for the next generation of scientists worldwide.


The conference is organized around three themes:

  • Water, Climate, Anthropocene
  • Extremes and Risks
  • Water, Energy and Carbon Processes

In the context of the conference themes, the sessions will focus on research that contribute to the following areas:

  1. Determination of the extent to which Earth’s water cycle can be observed and predicted
  2. Quantification of the inter-relationships between Earth’s energy, water and carbon cycles to advance our understanding of the system and our ability to predict it across scales
  3. Quantification of the anthropogenic influences on the water cycle and our ability to understand and predict changes to Earth’s water cycle
  4. Extremes in the water cycle and risks to society

An overview of each research area with associated topic(s) and sessions can be found at https://www.gewexevents.org/meetings/gewex-osc2024/program/themes-and-sessions/
