Theme IX. Tropical peatlands
We quantified in situ N2O fluxes during dry- and wet seasons and compared them with CO2 and CH4 fluxes at sites representing differing land uses and land use change intensities, i.e. non-drained and drained selectively logged peat swamp forest, deforested drained and burned peat, and agriculture on peat in Central Kalimantan, Indonesia.
The widest N2O flux amplitude was detected in the moderately drained forest. At the other flux monitoring sites the flux amplitude remained about 10× smaller. Annual cumulative peat surface N2O emissions expressed as CO2 equivalents of the total greenhouse gas (N2O, CO2 and CH4) emissions was typically ~1%, but at the highest 9.2%.
