Bio-economic evaluation of pasture-cropping, a novel system of integrating perennial pastures and crops on crop-livestock farms AgEcon
Finlayson, John D.; Lawes, Roger A.; Metcalf, Tess; Robertson, Michael J.; Ewing, Michael A..
Pasture-cropping is a novel approach to increase the area of perennial crops in mixed sheep and cropping systems. It involves planting annual cereals directly into a living perennial pasture. There is interest in subtropical grasses as they are winter dormant and their growth profile is potentially well suited to pasture-cropping. However, a wide range of factors can affect the uptake of such systems. This paper assesses the relative importance of factors that can influence decisions to introduce pasture-cropping. In this paper the research question is: what factors predispose a farm to take up a new technology such as (1) subtropical grass and (2) subtropical grass that is pasture-cropped. The analysis uses the MIDAS model of a central wheatbelt farm in...

Low Emission Farming Systems: A whole-farm analysis of the potential impacts of greenhouse policy AgEcon
Kingwell, Ross S.; Metcalf, Tess.
The Australian government is introducing a Carbon Pollution Reduction Scheme in 2010, as part of its climate change policy. After 2015 agriculture may be covered by this scheme. This paper examines how different broadacre farming systems may be affected by the policy settings of this scheme. Using the bio-economic farming systems model MIDAS (Model of an Integrated Dryland Agricultural System) the impacts of the Carbon Pollution Reduction Scheme on the profitability of different broadacre farming systems in the southwest of Australia are investigated. Results show a range of profit and enterprise impacts across the various farm types. In a scenario where agriculture is not covered by the scheme, reductions in profit range from 7 to 12 percent, attributable...
