Project Background
This work is part larger CIFOR projects
Global Comparative Study on REDD+ (GCS REDD+) – work in 6 countries
CIFOR is an international research organization working based on three pillars – research, capacity building and media outreach
This study is CIFOR research portfolio to address climate change

Outline of Presentation
Importance of peatlands for Indonesia
CO2 emissions from peatlands
Test site descriptions
Data and methods
Results
– Peatlands mapping using ALOS PALSAR data
– Above ground biomass assessment
Importance of Peatlands Ecosystem
Indonesia covers >80% (~20 Mha in 1990 out of 24 Mha) of tropical peatlands in SE Asia
1.1 Mha of intact peat swamp forests and 6.8 Mha of degraded peatlands forests were lost between 1990 – 2012
CO2 Emissions from Deforestation, Peat Drainage and Peat Fires in Indonesia
Peatlands contribute to 30 – 50% of total carbon emissions from forestry sector between 1990 and 2012
- In total, 83 sampling plots were collected during dry season in 2010- Circular nested sampling plots within 60 x 60 m2- Size of each sub plot 0.04 ha
Peatlands Mapping Results
SAR Data Preprocessing Data extraction, image registration, corrections and noise filtering
