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.

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.
