During this 21-year period they have backed this biotechnological variety that defends maize farming from attacks by boring beetles, which is an endemic plague present in certain areas of the Iberian Peninsula that causes great losses in production. To analyse the economic and environmental contributions of Bt maize farming in Spain and Portugal between 1998 and 2018, the GM Crops & Food magazine has published the report, ‘Twenty-one years of using insect resistant (GM) maize in Spain and Portugal: farm-level economic and environmental contributions’ by the agrarian economist, Graham Brookes.
