The IPCC has compiled the best available scientific methods into published guidelines for

estimating greenhouse gas emissions and emission removals from the land-use sector. In order

to evaluate existing GHG quantification tools to comprehensively quantify GHG emissions

and removals in smallholder conditions, farm scale quantification was tested with farm data

from Western Kenya. After conducting a cluster analysis to identify different farm typologies

GHG quantification was exercised using the VCS SALM methodology complemented with

IPCC livestock emission factors and the cool farm tool. The emission profiles of four farm

clusters representing the baseline conditions in the year 2009 are compared with 2011 where

farmers adopted sustainable land management practices (SALM). The results demonstrate the

variation in both the magnitude of the estimated GHG emissions per ha between different

smallholder farm typologies and the emissions estimated by applying two different accounting

tools. The farm scale quantification further shows that the adoption of SALM has a significant

impact on emission reduction and removals and the mitigation benefits range between 4 and

6.5 tCO2 ha?1 yr?1 with significantly different mitigation benefits depending on typologies of

the crop–livestock systems, their different agricultural practices, as well as adoption rates of

improved practices. However, the inherent uncertainty related to the emission factors applied

by accounting tools has substantial implications for reported agricultural emissions. With

regard to uncertainty related to activity data, the assessment confirms the high variability

within different farm types as well as between different parameters surveyed to

comprehensively quantify GHG emissions within smallholder farms.
