Biochar is the carbon rich product produced when biomass such as such as wood, manure or leaves, is heated with little or no available oxygen. The production and application of biochar into the soils offer multiple potential benefits:
Store organic carbon in the soil on a millennia scale thus providing climate change mitigation benefits;
Significant soil improvements, such as releasing nutrient elements, reducing nutrient leaching and gaseous losses, reducing soil acidity, increasing water holding capacity, and improving the soil fauna or soil biological function.
Biochar production also provides:
An efficient and renewable energy source;
A sustainable solution for the management of green wastes;
Economic benefits by creating new opportunities for local and regional businesses, increase government revenue, and create employment for the local people;
Social benefits through local community involvement and generate better public perception for biochar use for sustainable agricultural production (on-site biochar production using smaller units).
This biochar assessment project aims to evaluate the potential application of biochar technology in the Greater Mekong Sub-region (GMS). The project included all GMS countries, i.e. Cambodia, Lao PDR, Myanmar, Thailand, Viet Nam and Yunnan Province and Guangxi Zhuang Autonomous Region of the People's Republic of China (PRC).
