Savanna ecosystems are subjected to accelerating land use change as human demand for
food and forest products increases. Land use change has been shown to both increase and
decrease greenhouse gas fluxes from savannas and considerable uncertainty exists about
the non-CO 2 fluxes from the soil. We measured methane (CH 4), nitrous oxide (N 2 O) and
carbon dioxide (CO 2) over a complete wet-dry seasonal cycle at three replicate sites of
each of three land uses: savanna, young pasture and old pasture (converted from savanna 5 …
