36th International Symposium on Remote Sensing of EnvironmentBerlin, 10 – 15 May 2015

CIFOR Global Comparative Study on REDD+

GCS Module 3: REDD+ MRV and Carbon Emissions measurement

– Assessment of major deforestation drivers

– Setting national reference emission levels (RELs)

– Monitoring, reporting, verification (MRV) for REDD+

– Six case study countries: Brazil, Peru, Indonesia, Vietnam, Tanzania and Cameroon

What causes discrepancies in 2013?

Agreement and disagreement of forest loss / deforestation during 2000 – 2010- MOF (orange

polygon)- Margono (black)- INCAS (other

colors)

Systematic accuracy assessment exercise- Fine resolution Google Earth footprints imagery- Mosaic cloud free Landsat data 2000, 2005, 2010- Stratified random sampling points of verified forest loss 2000 – 2010- To verify Margono, INCAS, MOF forest loss data- Observe maps differences, Why? When?- Improve forest loss estimate 2000 - 2012

Deforestation estimate across main Islands

Contributions of CO2 Emissions by IslandsKalimantan and Sumatera contribute to ~80% of CO2 deforestation emissions 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

Land Use Types Following Forest Conversion

1990-2000

Forest definitions matter!
