Modelling Scenarios

Average GM content in conventional seed harvest

GM fields created as a percentage of total number of fields (including conventional fields)

GM field area estimated as a percentage of total field area (including conventional fields)

Scenario I: GM planted was obtained under exchange conditions, meaning that the seeds were obtained from other fielders as gifts or exchanged.

Scenario II: GM planted were obtained the seed market. This directly implies the use of commercial varieties.

Scenario III: GM planted was obtained from seeds saved from previous harvests.

Scenario IV: Single GM field introduced at the center of the study area. This suggests the scenario of a single GM field among 1,388 fields

Scenario V: GM planted obtained from food market. This scenario implies that variety planted was collected from quantities bought for food.
