Limited data on emissions in Africa translate into uncertainty during GHG budgeting. We studied annual CO₂, N₂O, and CH₄ emissions in four land-use types in Kenyan savanna using static chambers and gas chromatography. CO₂ emissions varied between seasons and land-use types. Soil moisture and vegetation explained the seasonal variation, while soil temperature was insignificant. N₂O and CH₄ emissions did not vary at all sites. Our results are useful in climate change mitigation interventions.
