Terrestrial carbon-cycle and vegetation models contribute to a better understanding of the dynamics of the terrestrial biosphere related to  the underlying processes and their relation to the terrestrial water cycle (see Section 6.3) and land use (see [[Agricultural economy and forestry]]). The [[LPJmL model]] ([[Sitch et al., 2003]]; [[Gerten et al., 2004]]; [[Bondeau et al., 2007]]) replaces the earlier IMAGE-2  carbon cycle and biome model ([[Klein Goldewijk et al., 1994]]; [[Van Minnen et al., 2000]]). Here, we give a general overview of the LPJmL model in the IMAGE context, with a focus on carbon and biome dynamics. For a detailed description of the IMAGE-[[LPJ] model|LPJ]] C cycle model and a sensitivity analysis, see (Müller et al., 2013<ref>[[Müller et al.,b (unpublished)]]</ref>).

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?
