COOL VEGE®: Concept and Scheme
http://coolvege.com/index.html
The agricultural products cultivated in fields
amended with biochar or biochar-compost are
sold under the “COOL VEGE®” eco-brand.
Biochar made by
local unused
biomass such as
overgrown
bamboo forests
COOL VEGE®: Concept and Scheme
Background of “COOL VEGE®” scheme
Unused bamboo forest
consequently overgrown
Bamboo forest
under management
⚫ Climate change
⚫ Decreasing and aging population in rural area →
Overgrown forests, abundant farmland;
⚫ Needed for sustainable agricultural realization;
←Sustainable rural development to secure food supply
COOL VEGE®: Concept and Scheme
Purpose of “COOL VEGE®” related projects
⚫ Scheme to guarantee the
willingness of famers to use
the practice (biochar);
⚫ Evaluation the framework to
scale up & out COOL VEGE®
scheme;
⚫ Social analysis (famer’s
income and consumer's
behavior)
