Challenges & opportunities for carbon sequestration in grassland systems A technical report on grassland management & climate Integrated Crop Management Series, Vol. 9
Langue : Anglais
Implementing grassland management practices that increase carbon uptake by
increasing productivity or reducing carbon losses (e.g. through high rates
of offtake) can lead to net accumulation of carbon in grassland soils –
sequestering atmospheric carbon dioxide (CO 2 ). Globally, the potential
to sequester carbon by improving grassland practices or rehabilitating
degraded grasslands is substantial – of the same order as that of
agricultural and forestry sequestration. Because practices that sequester
carbon in grasslands often enhance productivity, policies designed to
encourage carbon sequestering grassland management practices could lead to
near-term dividends in greater forage production and enhanced producer
income. Practices that sequester carbon in grasslands also tend to enhance
resilience in the face of climate variability, and are thus likely to
enhance longer-term adaptation to changing climates. Developing policies
to encourage the adoption of practices that sequester carbon has several
significant challenges, such as demonstrating additionality, addressing
the potential for losses of sequestered carbon, and engaging smallholders
and pastoralists with uncertain land tenure. In addition, the paucity of
data in developing countries hampers the measurement, monitoring and
verifying of carbon sequestration in response to those practices. This
report reviews the current status of opportunities and challenges for
grassland carbon sequestration. Based on these observations, the report
then identifies components that could foster the inclusion of grasslands
in a post-2012 climate agreement, and the development of policies to
improve grassland management.
