Management practices that reduce greenhouse gas emissions from farms or increase on-farm carbon storage can contribute to climate change mitigation. Farmers, however, are only likely to adopt new management practices if they contribute to farm profitability. We use the Agricultural Production Systems sIMulator (APSIM) to simulate how different cropping practices contribute to greenhouse gas aba...

tation of productive new technologies that provide more food, shelter, and industrial materials for an expanding world population. Agricultural output needed to produce an abundant food supply for nations where economies and distribution systems are adequate is currently achieved on approximately six million square miles of cultivated land, the same land use as in 1950, despite a doubling in wo...

This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included ...

The rise in the world demand for food poses a challenge to our ability to sustain soil fertility and sustainability. The increasing use of no-till agriculture, adopted in many areas of the world as an alternative to conventional farming, may contribute to reduce the erosion of soils and the increase in the soil carbon pool. However, the advantages of no-till agriculture are jeopardized when its...

There are relatively few Federal environmental regulations that influence agricultural production in the US. However, many local and state environmental rules may influence the management practices on US farms as might interactions between urban population centers and agricultural producers. Detailed analysis of corn farms gives insight into these relationships and suggests that stringent envir...

The purpose of this study was to determine the perceptions of Iowa agricultural education teachers and students about sustainable agriculture. The teacher population for the study included all secondary school agricultural education teachers in Iowa (N=248). A stratified random sample of 60 teachers (schools) was selected, I O from each of the six FFA districts. Teachers in the sample were aske...

Current agroecosystem management practices in tropical latitudes may not be an economically feasible and an effective long-term adaptation strategy to climate change. As such, implementing, improving and refining sustainable land management practices may be a more effective adaptation strategy. This study determined the perception and knowledge of climate change by landowners in a remote Costa ...
