Global Situation
The global cultivation of genetically modified (GM) plants has increased since commercialisation in 1996. The area increased from 1.7 MHa in 1996 to more than 170 MHa in 2012 (Figure 1). The main GM crops are soybean (80.7 MHa), corn (55.1 MHa), cotton (24.3 MHa) and canola (9.2 MHa).
