BLUEGEM

• IPSL (Institut Pierre Simon Laplace, France) federates 8 research laboratories with a mission to foster and coordinate research on climate and environment changes. The IPSL climate model has been involved in all the CMIP phases since 1995. The PI for IPSL and BLUEGEM lead, Agnès Ducharne, conducts research on the links between land surface hydrology and the climate system, with a major focus on groundwater and anthropogenic pressures. She belongs to the group developing the ORCHIDEE land surface model, like the other IPSL task leaders: Frédérique Cheruy (land-atmosphere coupling, atmospheric parametrizations); Bertrand Guenet (soil carbon); Aglaé Jezequel (extreme events; science-society relationships); Philippe Peylin (carbon cycle, data assimilation); Jan Polcher (water cycle, human influences, co-chair of the GEWEX Scientific Steering Group). The IPSL group also includes Philippe Ciais, among the top-cited researchers in Geosciences and Environment, and co-chair of Global Carbon Project.
• INRAE (Institut national de recherche pour l'agriculture, l'alimentation et l'environnement, France) is involving its laboratory of Public Economy. The PI is Pierre-Alain Jayet, economist, focusing on the relationships between agriculture and the physical environment and their economic regulation, in the framework of climate change.
• at U-Tokyo (Japan), the PI is Hyungjun Kim, with an overall research goal to understand how water, climate and society are interconnected within the Earth System, and a recognized expertise in bias-correction and downscaling methods. He has been actively involved in CMIP6 coordination. 
• at NTU (National Taiwan University, Taiwan), the PI is Min-Hui Lo (Department of Atmospheric Sciences), who combines  climate modelling (with CESM) and satellite data to explore how land surface process and land use changes impact regional and global climate. He developed the GW parameterization in CLM/CESM. Dr. Sherry Kuo (affiliated to Academica Sinica) works on sociological and political dimensions of environmental and sustainability problems, such as climate change and natural disasters, and will co-lead social and transdisciplinary tasks.
• MSU (Michigan State University, USA) is represented by two PIs: Yadu Pokhrel (Department of Civil and Environmental Engineering) focuses on how the water cycle responds to the combined effects of climate change and human activities, and he pioneered the representation of these human factors, including irrigation and GW pumping, into global/regional hydrologic models; Dan Kramer (James Madison College - public affairs and public policy) focuses on how local communities respond and adapt to infrastructure development and how these changes affect human/environment interactions. This research involves analyzing the integration of natural and human systems.

• OFB (French Biodiversity Agency, France, PI: Claire Magand) is a national public agency under the Ministry of Environment. Its missions include to implement a sustainable management of water resources under global change, and to support related research.
• MRC (Mekong River Commission, Laos, PI: Thym Ly) is an inter-governmental organization that works directly with the governments of Cambodia, Laos, Thailand, and Vietnam to jointly manage the shared water resources and the sustainable development of the Mekong River. It has signed a “memorandum of understanding” with MSU to jointly work on issues related to climate change and socio-economic development in the LMRB.
