Abstract. Peatland use for sago palm plantation can emit greenhouse gases (CH4, CO2, N2O) to the atmosphere.The aims of the study was to determine the flux dynamics of CH4 and CO2 in sago palm.The study on the dynamic of methane (CH4) and carbondioxide (CO2) fluxes from sago palm plantation in Papua peat land was conducted using a closed chamber technique. Fluxes of CH4 and CO2 were measured every three months, beginning on April 2013 until March 2014.Results, showed annual CO2 emissions at 34,88 tCO2-e ha-1 yr-1 and CH4 emissions at 9,96 t CO2-e ha-1 yr-1. Temporal variation of the measured CO2 was very high suggesting the need for a higher frequency measurement. CO2 and CH4 fluxes were neither influenced by carbon stock nor peat thickness.
