Abstract:

In Europe, a product is GM if it contains more than 0.9% of GM material. During harvesting, crops from many fields are combined to fill a silo. To avoid the risk of mixing GM and non- GM crops it is possible to specify GM and non-GM silos or to define times for GM and non-GM delivery at silos. A model of farmers' variety choice, based on profit and taking into account transport cost and the price and cost difference between GM and non GM crops, is proposed to determine the consequences of these strategies for agricultural land. The delivery timing strategy leads to a uniform area of GM or non-GM crops depending on prices and weather risks. The spatial strategy leads to areas of either GM or non-GM crops around the corresponding collection silos. The size of these zones depends on yields, price differences and transport costs.
