This presentation, delivered at the 36th International Symposium on Remote Sensing of Environment, outlines the issue of national forest mapping in Indonesia. The importance and variability of forest definition is highlighted.

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

2. 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

3. Outline of Presentation
 Common problems of national forest mapping in Indonesia
 Satellite data classification and approaches
 Comparison of available maps of forest loss/deforestation
 Needs for systematic accuracy assessment
 Drivers of deforestation analysis

7. Available datasets
 Land cover map of MOF (1990 - 2013)
 WRI Global Forest Watch data/GFW (2000 – 2013)
 Annual primary forest loss map of University of Maryland – from
Margono study (annually, from 2000 - 2012)
 Indonesian National Carbon Accounting System (INCAS), LCCA
project by Indonesian National Aerospace Agency (LAPAN)
(annually, from 2000 – 2012)

What causes
discrepancies in 2013?

9. Agreement and
disagreement of
forest loss /
deforestation
during 2000 – 2010
- MOF (orange
polygon)
- Margono (black)
- INCAS (other
colors)

10. 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

11. Deforestation estimate across main Islands

12. Contributions of CO2 Emissions by Islands
Kalimantan and
Sumatera contribute
to ~80% of CO2
deforestation
emissions between
1990 – 2012

13. 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

14. Land Use Types Following Forest Conversion
1990-2000

15. Forest definitions matter!
