1. GHG (CO2, CH4 & N2O) Fluxes and Carbon Stocks
Associated with Land Use Change
in Tanjung Puting National Park, Central Borneo
Nisa Novita, Kristell Hergoualc’h, J.Boone Kauffman

2. Objective
Peatswamp Forest Oil palm Plantation
Hydrology? Soil properties?
Δ N 2O ?
Carbon Fertilization?
storage? Δ CH4 ? Redox?

3. Expected Result
• Methane flux
• Nitrousdioxide flux
• Soil respiration (CO2) flux
• C ­ storage (incl. slash and burn effect)
• Peat characteristics (physical and chemical properties)
• Hydrology (water table depth, rainfall, etc)
• Litterfall rate
• Redox potential
• Fertilization application effect
• Litter decomposition
