2 Deforesta;on Monitoring in Brazil by L- band SAR on JERS- 1/ALOS 1995 (JERS- 1) JAXA,METI 2007 (ALOS) JAXA 600km l ApplicaEon for deforestaeon monitoring by provision of ALOS/SAR data to IBAMA (Brazilian InsEtute of Environment and Renewable Natural Resources) l ContribuEon to declinaeon of deforestaeon area in Brazil 1

3 Advanced Land Observing Satellite- 2 "DAICHI- 2" (ALOS- 2) ALOS- 2 in- orbit configura;on Y X Z Data relay antenna Solar Arrays L- band SAR antenna X- band downlink antenna Daichi (ALOS)( ) ALOS- 2/PALSAR- 2 was launched on 24 May 2014, and is now opera;onal. L- band Synthe;c Aperture Radar- 2 (PALSAR- 2) Wide observable area (2,320km) Right- and- le^ looking func;on High resolu;ons (1-3m) Dual Polariza;on(HH+HV) ScanSAR Strip Mode SAR capable of observing day and night, and in all weather condi;ons. Succesor of ALOS/JERS- 1 using same forest observa;on capabilty from 1990s ALOS- 2 will achieve significant contribu;ons to: n Disaster Monitoring of Damage Areas n Con;nuous upda;ng of data archives related to na;onal land and infrastructure n Effec;ve monitoring of cul;vated areas n Global monitoring of tropical rain forests to iden;fy carbon sinks. 2

15 Concept of the analysis system Ø JICA plans to expand their project internationally to such as Peru, Columbia(South America), Myanmar(Asia), Gabon(Africa), etc., not only Brazil deforestation Monitoring Project. Ø At that time, it is not to be installed analysis system in each country, but it will be constructed a Forest change detection system for intensive analysis. It will be ensured the horizontal deployment efficiently. Analysis system delivered to each country ScanSAR Image (big data, station limtted) Total analysis system built in Japan Forest/Nonforest Data (small data, fullopen to public) FTP A-country B-country C-country A-country B-country C-country ALOS era(2007~2011) ALOS-2 era(2016~) 14
