The macro implications of a complete transformation of usa agricultural production to organic farming practices

, : The macro implications of a complete transformation of usa agricultural production to organic farming practices. Agriculture Ecosystems & Environment 10(4): 323-334

A national interregional linear programming model of USA agriculture is used to evaluate and compare 2 conventional and 3 organic production alternatives. The effects on production, supply prices, land use, farm income and export potential, of a complete transformation of USA agriculture to organic practices, are estimated. Crop yields and production costs are estimated for 150 producing regions for 7 crops under both conventional and organic methods. Compared with conventional methods, widespread organic farming leads to a decrease in total production, lower export potential, higher supply prices, higher value of production, lower costs of production and higher net farm income. The USA domestic crop demand can be met with organic methods, but would be more expensive. Some interregional shifts in crop production would also occur.
