Terrestrial carbon cycle and vegetation models contribute to better understanding of the dynamics of the terrestrial biosphere in relation to these underlying processes and to the terrestrial water cycle (see Component [[Water]]) and land use (see Component [[Agriculture and land use]]).

The IMAGE-2 carbon cycle and biome model ([[Klein Goldewijk et al., 1994]]; [[Van Minnen et al., 2000]]) have been replaced by the Lund-Potsdam-Jena model with Managed Land ([[LPJmL model|LPJmL]]) model ([[Sitch et al., 2003]]; [[Gerten et al., 2004]]; [[Bondeau et al., 2007]]). An overview of the LPJmL model in the IMAGE context with regard to carbon and biome dynamics is presented here; the model and a sensitivity analysis is described in detail by Muller et al. ([[Müller et al., in revision|in revision]]).

Key policy issues

  • What is the role of the terrestrial biosphere in the global carbon cycle, how will it change in time as a result of climate and land-use change?
  • To what extent can the terrestrial biosphere contribute to reducing the accumulation of CO2 in the atmosphere and what are viable mechanisms?
  • What opportunities exist to reduce land-use related carbon emissions (e.g. REDD) and even enhance the carbon uptake through the establishment of new forests.
  • What are the contributions of land-use change, climate change and CO2 fertilization on the future carbon cycle and how can these be considered in climate policies?
