Food security adaptation mitigation: Parallel session L1: regional dimensions. Paris: CSA-Ciradc2015  ap. 147.  aBrazilian inventory of enteric CH4 emission is currently based on the IPCC Tier 2 approach. Although IPCC recommends the use of a more specific Tier 3 approach, this is hampered by a lack of consolidated data for the development, evaluation and application of such a Tier 3 approach. The purpose of this study was to compare a dynamic, mechanistic model of enteric fermentation currently used as a Tier 3 approach in the Dutch GHG inventory for dairy cattle with the Tier 2 approach used in current Brazilian GHG inventory for beef cattle production systems.  aBeef cattle  aMethane  aGado de corte  aMetano  aEnteric fermentation1 aLIMA, J.
