Earth System Science Partnership IHDP WCRP IGBP Diversitas Joint Projects on Global Sustainability Carbon Water Food

A partnership of three global environmental change programs September 2002

Global Carbon Project Mandate u Synthesis of knowledge of the global carbon cycle, within a coherent research framework u Coupling the biophysical and human dimensions of the global carbon cycle u Coordination of regional and national carbon programs in the context of a global effort

Anthropogenic C sources u Earth at night

Global Carbon Project Science Themes 1. Patterns and Variability u What are the geographical and temporal patterns of carbon sources and sinks? 2. Processes, Controls, and Interactions u What are the controls and feedback mechanisms – both anthropogenic and nonanthropogenic – that determine the dynamics of the carbon cycle on scales of years to millennia? 3. Carbon Futures u What are the likely dynamics of the global carbon cycle into the future?

Global Carbon Project Operational structure u Scientific Steering Committee (15 members plus 3 co-chairs) u Executive Subcommittee of SSC u Offices (each with an executive officer, possibly shared with another program) • Australia • US • Japan • Others u Working with other projects and stakeholders • GCP Framework document: now under community review • Joint implementation (SCOPE, IGCO, Ocean CO 2, …) • Scientific Advisory Committee

GECAFS logo Food Systems Given changing demands for food, how will climate change additionally affect food provision and vulnerability in different regions and among different social groups? How might different societies and different categories of producers adapt their food systems to cope with climate change against the background of changing demand? What would be the environmental and socioeconomic consequences of such adaptations?

Water Resources What are the relative magnitudes of global scale changes in the global water system due to human activities and environmental factors (e. g, climate change)? What are the main mechanisms by which human activities are affecting the global water system? To what extent is the global water system resilient and adaptable to global change (e. g. , climate change, biodiversity, economic and management changes)? Image needed
