Biochar and climate change
The natural carbon cycle includes natural char production from wildfires, the ensuing
transport of char from the soil to watercourses and the ultimate burial in marine or estuarine
sediments. Since routine and universally acceptable methods for black carbon and
specifically charcoal are still outstanding, the precise magnitude of the rates and processes,
and the relative size and stability of char in the soil and sediment pools are still uncertain
(Schmidt, 2004; Simpson and Hatcher, 2004b). However, the potential to enhance the
contribution that char makes to the natural carbon cycle through the addition of biochar in soil
is a topic of much public discussion and a rising profile in influential policy circles, for
example, in Australia (Garnaut, 2008). The contribution that such strategies can have on
climate change mitigation depends on attaining a much more extensive research base and
detailed economic analyses.
It is useful to consider a biochar-based strategy against more established approaches to
increase the organic carbon stored in soil, such as the use of manures and composts. The
longevity of biochar in the soil is an important element when comparing pyrolysis bioenergy
and biochar production with conventional bioenergy strategies, in mitigating climate change.
However, it is also vital to assess any indirect reduction in net greenhouse gas emissions
from agriculture through the use of biochar. There may be additional benefits arising from the
contribution of biochar to facilitating agricultural development and improving the socioeconomic
circumstances of farmers in developing countries. Figure 9 captures the
complexity of potentially beneficial interactions of biochar in the context of natural cycles and
anthropogenic interventions.
