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?
