Abstract
Biochar, a carbon-rich material from biomass combustion, is a key carbon-negative strategy for climate change mitigation. It enhances soil health and prevents the release of carbon and methane during plant decomposition. Biochar locks away carbon in a stable form for centuries and could remove up to 12% of annual greenhouse gas emissions. It also has the potential for large-scale use due to its low production cost and multiple benefits. Biochar improves soil fertility, promotes plant growth, and reduces the need for chemical fertilizers. It creates a nutrient-rich environment for soil microbes, enhancing crop yields. Its water retention ability prevents water stress in fast-draining soils and aids aeration in compacted soils. Biochar is a vital tool for climate change mitigation and soil health enhancement. This chapter explores biochar’s dual role in these areas.
