MANAGING CARBON IN RURAL AUSTRALIA

摘要

The extent of emissions from various sectors of the Australian economy are described and commitments to international agreements (e.g. Kyoto) explained. The contribution from Australian agriculture to the national emissions total is quantified. Methods by which the agricultural sector might contribute to greenhouse gas abatement are discussed, the two key responses being the reduction of emissions at source, and storage of additional carbon to offset emissions elsewhere. Agricultural practices that might achieve these outcomes are discussed and include livestock management, conservation farming, and conventional and farm forestry. Many of these practices are, themselves, beneficial to agricultural production but might also offer potential for additional income should carbon credits trading take place. Before it is possible to determine the likely financial benefit, a number of issues require clarification (e.g. quantification of the carbon stored will require the development of accurate and verifiable accounting schemes). A requirement will also be the development of market mechanisms by which carbon can be traded. Despite current uncertainties with Kyoto agreement negotiations, it is probable that greenhouse gas abatement policies will survive. Judicious use of available agricultural practices and technologies might therefore yield future financial benefits for landholders.
