In order to quantify greenhouse gas fluxes from typical eastern African smallholder farms, we measured flux rates every week for 1 year at 59 farms in western Kenya. These upland soils tend to be small sinks for CH4
and small sources of N2
O. The management intensity of the farm plots had no effect on emissions, likely because the variability was low. Plots with trees had higher CH4
uptake than other plots. This suggests that emissions from small, low-input farms in this region are quite low.
