||Future global carbon cycle dynamics under climates altered by increased concentrations of greenhouse gases (GHGs) will be defined in part by processes which control terrestrial biospheric carbon stocks and fluxes. Current research and modeling activities which involve terrestrial carbon have focussed upon the response of unmanaged vegetation to changing climate and atmospheric chemistry. A common conclusion reached from exercising geographically-explicit terrestrial carbon models is that more carbon would be stored by equilibrium vegetation controlled by a stable GHG-warmed climate than by equilibrium vegetation from current (stable) climate. Here, the authors examine the potential impact on the terrestrial carbon cycle if global agriculture increased to the limits permitted by future GHG-induced climates. The authors determined climatic limits to global agricultural zones, projected the new climatic limits to agricultural zones, then calculated the amount of carbon the terrestrial biosphere would store under the new climate and agricultural conditions. The authors conclude that loss of carbon to agriculture could be as important as gain of carbon by climate of an equilibrium biosphere. (Copyright (c) Inter-Research 1993.)
