(In and) Out of Africa: Estimating the Carbon Exchange of a Continent
Date: Wednesday, September 28 @ 15:45:00 MDT

by Niall Hanan

Understanding the diverse elements of the global carbon cycle has been the focus of much recent research [Prentice et al. 2001, Schimel et al. 2001, Gurney et al. 2002, House et al. 2003]; research that is vital to our understanding of the missing sink, future atmospheric carbon dioxide concentrations, and future climate [Fan et al. 1998, Houghton et al. 1998]. Much research has concentrated on carbon dynamics of the large ocean basins [Lee et al. 1998, Le Quéré et al. 2003] and terrestrial exchange in North America and Eurasia [Pacala et al. 2000, Schimel et al. 2000]. Despite representing 20% of the global land mass, Africa has thus far been largely neglected in these studies. We will examine current understanding of carbon stocks and fluxes within Africa and discuss how uncertainty in global carbon dynamics arises in part from uncertainty in the African components. We outline areas where new measurements and research in Africa can contribute to understanding at both continental and global scales.
