The G-res Tool

Expert committee

The expert committee is constituted of distinguished experts that will guide and monitor the development of the G-res Tool by insuring high quality scientific research and review. They are the key resource in answering technical questions and resolving any scientific disputes.

The establishment of the G-res Tool Expert Committee allows us to ensure the scientific rigour of the tool if and when updates do occur.

Yves Prairie is a full professor of biology at the Université du Québec à Montréal. A founding member of the GRIL research center (a multi-university research centre in limnology since the early 1990s), he was its director for 9 years. His main research focus is on all aspects of carbon cycling in both lakes and reservoirs. He initiated and co-led the NCEAS working group on the role of lakes and reservoirs in the global carbon budget. He holds a UNESCO Chair in Global Environmental Change and was the President of the International Society of Limnology (SIL). His research interests combine carbon and nutrient biogeochemistry, statistical modelling of ecosystem processes, and physical limnology.

Dr. Alm has worked on carbon cycling and GHG exchange (CO2, CH4, N2O) at terrestrial / aquatic environments such as peatlands, lakes, reservoirs, forestry buffer zones and soil freeze thaw cycles. He has also worked on forest soil carbon inventories in emerging economies in Asia and Africa. Since the year 2004 Dr. Jukka Alm has served IPCC as Lead Author in his areas of expertise, contributing to several Guidelines for National GHG Inventory (2006 IPCC AFOLU Guidelines, IPCC Reporting Software, 2013 IPCC Wetland Supplement, and the 2019 IPCC Refinement to the 2006 IPCC Guidelines). He has published more than 60 scientific papers in international journals and numerous other scientific publications. Dr. Alm is currently an expert member in Finnish Ramsar Wetland Working Group, member of the Scientific Advisory Board of the GHG Inventory Project in Finland. His current interest is to contribute in development of GHG inventory methods for flooded lands, especially freshwater reservoirs.

Atle Harby is a senior research scientist at SINTEF Energy Research in Norway. He has more than 20 years of experience in research in hydropower and regulated rivers with emphasis on environmental impacts from hydropower, climate change impacts, greenhouse gas emissions from reservoirs, energy storage technologies and the integration of hydropower services in energy and water management. Since 2009, he is the Director of the research centre CEDREN (Centre for Environmental Design of Renewable Energy), an interdisciplinary research centre for the technical and environmental development of hydropower, wind power, transmission lines and the implementation of environmental and energy policy. He has taken part in the development of the G-res tool, and has served for the IPCC to write guidelines on how to report GHG emissions from flooded land.

Dr. John Harrison holds an Edward R. Meyer Distinguished Professorship in Washington State University’s School of the Environment where he directs the Global Change and Watershed Biogeochemistry Laboratory.  Harrison holds a B.S. in Biology from Brown University and a Ph.D. in Geological and Environmental Sciences from Stanford University.  At WSU Vancouver, Harrison and his research group use experiments, measurements and models to better understand the sources, transformations, fate, and consequences of macronutrient enrichment and greenhouse gases in streams, lakes, rivers, reservoirs, and the coastal zone.
