A bioeconomic model of carbon trading within an Australian grazing enterprise AgEcon
Gowen, Rebecca; Rolfe, John; Donaghy, Peter.
The Carbon Farming Initiative (CFI) and other carbon trading programs have been promoted as alternative sources of income for agricultural producers, particularly those on marginal land. This paper presents the results of a bioeconomic model developed to compare the relative returns from a beef enterprise against changing regrowth management practices to sequester additional carbon and sell carbon offsets. The model is constructed based on a 1000 hectare parcel of land in Central Queensland and is calculated for two landtypes; Brigalow and Eucalypt. Assuming zero transaction costs and a 20 year contract period, a carbon-cattle enterprise has higher returns that a cattle-only enterprise at relatively low carbon prices for both land types. However, results...

Assessing the economic impact of an emissions trading scheme on agroforestry in Australia’s northern grazing systems AgEcon
Donaghy, Peter; Rolfe, John; Gowen, Rebecca; Bray, Steven; Madonna, Hoffman.
Although agriculture generates a significant portion of Australia’s greenhouse gas emissions, it also has the potential to sequester large quantities of emissions through changed land use management such as agroforestry. Whilst there is an extensive amount of agroforestry literature, little has been written on the economic consequences of adopting silvopastoral systems in northern Australia. This paper reports the economic feasibility of adopting complimentary agroforestry systems in the low rainfall region of northern Australia. The analysis incorporates the dynamic tradeoffs between tree and pasture growth, carbon sequestration, cleared regrowth decomposition rates and livestock methane emissions in a bioeconomic model. The results suggest there are...

Consumer demands for organic and genetically modified foods AgEcon
Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W..
Issues concerning consumer demands for genetically modified and organic food remain topical. It is unclear how consumers perceive issues associated with food production such as food safety, environmental impacts or animal welfare. It is also unclear how consumers might value potential changes in those issues in regional and metropolitan centres. This paper reports on research using the choice modelling technique to estimate and compare consumer demand for genetically modified and organic foods in Australia. The case study considers tomatoes, milk and beef commodities. The results draw comparisons between the contribution of associated factors influencing consumer purchasing decisions in a regional and metropolitan city. The results are relevant to the...

Estimating the economic and environmental tradeoffs of altering grazing intensity for specific land types in the Fitzroy Basin AgEcon
Star, Megan; Donaghy, Peter; Rolfe, John.
The Fitzroy Basin is one of the largest catchment areas in Australia covering 143,000 km² and is the largest catchment for the Great Barrier Reef (GBR) lagoon. Recent research has identified that poor water quality is having negative impacts on the GBR. Grazing beef cattle is the dominant land use in the Fitzroy Basin (90% by area) and has been identified as the major contributor of sediment (~%90) and organic nutrient loads to the GBR lagoon. A bioeconomic model has been developed which determines the cost ($/tonne of sediment) incurred by graziers in implementing strategies that increase ground cover and land condition. The results demonstrate the implications of land type, grazing pressure, tree basal area and enterprise operation on optimal grazing...

Productivity tradeoffs and synergies for grazing lands in central Queensland to generate carbon offsets AgEcon
Gowen, Rebecca; Rolfe, John; Donaghy, Peter.
This paper reports research seeking to understand the economic implications for central Queensland graziers of participating in a carbon trading scheme and to measure the likely participation of graziers in an emissions trading scheme under various market design scenarios. An initial desktop study was undertaken to compare an enterprise which produced only cattle to one which produced cattle and sequestered carbon. The findings from this analysis were used to inform the design of an experimental auction to test alternative carbon trading scenarios. An experimental workshop was conducted at seven locations across central Queensland with a range of beef producers, extension officers and consultants. Participants were presented with a scenario in which they...

Quasi-option values for enhanced information regarding genetically modified foods AgEcon
Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W..
Issues concerning the long-term environmental and health risks associated with the production of genetically modified foods remain highly topical in Australia. It is unclear how consumers values for a precautionary approach to the release of genetically modified crops compares to the opportunity costs of forgoing economic growth associated with the use of these technologies. In this paper, an application of the contingent valuation method is reported. That technique was used to estimate quasi-option values held by consumers regarding a potential five year moratorium on the use of genetic modification in Australian agriculture. The results are compared to the estimated opportunity costs of imposing such a ban o Queensland consumers.

Unravelling the economic and environmental tradeoffs of reducing sediment movement from grazed pastures AgEcon
Donaghy, Peter; Rolfe, John; Gaffney, James.
An undesirable consequence of grazing activities in eastern Australia is the quantity of sediment emptying into the Great Barrier Reef Lagoon. One of the challenges to reducing sediment loads stems from the lack of private incentives to improve land management practices. There is also a poor understanding of the financial implications resulting from the adoption of sustainable management practices, and, in particular the lack of scientific and economic knowledge linking on-farm management actions to catchment scale impacts. Bio-economic modelling has been used to identify the economic and environmental trade-offs encountered when grazing strategies are altered to reduce off-farm sediment movement from a black spear grass pasture in central Queensland.

Welfare Benefits: the changing face of the Queensland beef industry. AgEcon
Rolfe, John; Donaghy, Peter.
Australian agriculture has suffered from a long-term decline in its terms of trade and a persistent cost-price squeeze. The effects on farm viability have led to declining and aging rural populations, rising rural unemployment, and substantial agricultural restructuring. To cushion these effects and assist in rural restructuring Australian State and Federal Governments have provided support to primary producers including drought aid, reconstruction aid and other support mechanisms. In Queensland the principle agency responsible for providing this support is the Queensland Rural Adjustment Authority (QRAA). This paper will examine the recent pattern of support QRAA has provided the Queensland beef industry and comment on its effectiveness and flow-on effects.
