Resumen
Descripción
The results of this analysis show that a long-term tree crop plantation is effective at reducing carbon emissions from a predominantly grazing farming system. However, if the plantations are destumped, much of the carbon will be returned to the atmosphere in time, in which case benefits are confined to their ability to ‘buy time’ for the development of less-polluting technologies. The accreditation of commercial tree crops may provide a socially and politically feasible solution for medium-term environmental policy. The benefits of the policy would be strengthened if implemented in conjunction with salinity abatement policy.
