The demand for organic food products has expanded rapidly in the past decade on a global basis, stimulated by consumer perceptions that organic products are safer, cleaner and more ethical than conventional products. The demand for organic products was estimated to grow at a rate of 15-20 per...

This study estimates how potential carbon policies targeted at reduction of greenhouse gas (GHG) emissions could affect selection of rice cultivars by conducting a life cycle assessment of GHG emissions and estimating the carbon sequestered for fourteen commonly sown rice cultivars across...

This is the third of a series of papers examining the potential economic effects from the introduction of a hypothetical low cholesterol pork product into the Australian market. Here, a newly updated pig meat model reported by Griffith et al. (2010) is used to model the industry wide impacts of...

This paper is a summary of some of the considerations involved in applying an existing model to a new problem, in particular in deciding whether to update or not, and some of the issues involved in interpreting the output from the new application. Thus where you start from does influence where...

Switchgrass (panicum virgatum L.), a viable option for second-generation renewable fuels, has an extended harvest window with optimal harvest affected by yield, storage losses and nutrient uptake. This research shows that optimal harvest occurs later than maximum yield for Haskell, OK and...

A spreadsheet-based tool that tracks cow-calf producer net returns (NR) and greenhouse gas (GHG) emissions was used to determine the impact of calving season for three typical farm sizes and four fertilization strategies in Arkansas. Economic and environmental changes were examined for spring,...

Concern over GHG emissions has producers analyzing cattle production alternatives. One way producers can modify emissions is by changing herd sire genetics. The ‘Bull Estimator’, part of a recently developed cow-calf profitability and GHG spreadsheet tool, shows that genetic change can...

This study estimates the impact of carbon offset payments on land use choices, net producer returns, and carbon sequestration. Loblolly pine is added to traditional cropping choices as a designated carbon-sequestering crop. With a carbon offset price of $15 per ton, pine enters land use on 10...

Using life cycle assessment methodology, this analysis evaluates how two carbon reduction strategies affect cotton plantings regionally and methods used to produce cotton. Because cotton production emits large amounts of carbon, the design of a reduction policy as either excluding soil...
