1 EFFECT OF LAND-USE MANAGEMENT ON GREENHOUSE GAS EMISSIONS FROM TROPICAL PEATLANDS

Tropical peatland forests are changing rapidly to meet the food demands of the growing population and economic development. We report greenhouse gases emissions from secondary forest to paddy field and rice-soybean rotation field in South Kalimantan, and upland in Jambi, Indonesia. Gas samples were taken from peatland surface and analyzed for CO2, CH4 and N2O. Land-use change from forest to paddy field significantly decreased the CO2, but increased CH4 emission. Change from forest to paddy-soybean rotation field significantly reduced N2O and CO2 emissions, but had no significant influence on CH4 emission, so Global Warming Potential should be considered
