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.
