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 can store carbon and improve soils.

The land suitability layer has been simplified for ease of viewing on all connection speeds. For a detailed look at land suitability for biochar application in the GMS, please see the printed map linked above.
1. Biochar Hotspots are areas of high biochar production (available biomass) and application (suitable soil and land conditions) potential and were selected in consultation with national counterpart agencies including consideration of government priorities and socio-economic factors.
2. Soil data quality in the GMS region is varied and different soil classification systems have been used in GMS countries. The best available data has been compiled to produce a GMS soil map based on the FAO-UNSECO classification system (1988, 1997).
3. The Land Suitability for Biochar Application layer was developed through combining information on soil type, slope and areas currently under cropping land use. It ranks suitability purely in terms of biochar application to the land and does not include availability of biomass, socio-economic conditions and other additional factors that were considered in identifying Biochar Hotspots.
4. The Greater Mekong Subregion (GMS) includes Cambodia, Lao PDR, Myanmar, Thailand, Viet Nam and Yunnan and Guangxi provinces of the PRC.
