Agriculture is of relevance to climate change due to emissions in food production and emissions through land-use change. Collectively, these account for carbon-equivalent emissions equal, globally, to that of transport and since agricultural emissions are affected by fertilizer application and the extent of the livestock sector, emissions are—as for transport—expected to increase at a faster rate than population growth per se, as a function of wealth creation and dietary change. However, the fact that agricultural land is actively managed means that the emissions can potentially be mitigated or reversed. Agricultural soils contain a relatively small proportion of the global soil carbon pool, but this quantity is significant relative to the annual atmospheric flux. Biochar comprises biomass in a deliberately stabilized form, for which the soil may provide storage on a very large scale. With requisite physical and chemical properties, these forms of carbon could still offer potential value to crop productivity through dynamic or reversible interactions with nutrients and soil mineral particles. Any improvement to the productivity of existing agricultural land has the potential to ease pressure on biodiverse and often carbonrich natural ecosystems. It is in this context that biochar has emerged as a potential win–win strategy for climate change mitigation and food production at the global scale.
