JAXA
123rd CEOS Plenary I Phuket, Thailand I 3-5 December 2009
The Kyoto & Carbon Initiative• International collaborative project led by JAXA EORC.• Continuation of Global Rain Forest and Global Boreal Forest Mapping project .• Aims to support information needs posed by:
– Multinational Environmental Conventions and Declarations:• UNFCCC Kyoto Protocol (Land Cover change);• Ramsar Treaty on Wetlands (wetland characteristics and disturbances);• UN Millenium Declaration & WSSD (water supply and water management);• Other international convention (Biodiversity[CBD] and Desertification [UNCCD]).
– The terrestrial carbon cycle science community (CO2 & CH4 sources and sinks);

Monitoring deforestation (1/2)• Clear cut region can be
identified as the small backscattering area.
• Estimation of the deforestation time-change can be monitored.
6Surface scattering and the volume scattering.( Red arrow shows the back scattering )

Monitoring deforestation (2/2)
Repeat observation covering wide area in short time
Continuous observation is planned by GCOM-C

Future Plan on ALOS K&C1. Continue Data Acquisition/Processing, Mosaics
generation2. Continue and improve Biomass Estimation &
Forest/Non-Forest Classification3. Comparison with data in 1990s 4. Data Analysis in Wide Area
