The South African National Biodiversity Institute (SANBI) recently released the outcome of the
South Africa–Norway bio-safety cooperation project ‘Monitoring the environmental impacts
of GM maize in South Africa’. This project studied possible impacts of commercial genetically
modified (GM) maize (MON810 maize), containing the Cry1Ab protein (Bt-protein), on the South
African environment.1 The report addresses concerns about Bt-technology in GM maize in South
Africa, in particular the development of possible resistance of target insects to the Bt-toxin and of
unintended effects of GM maize on non-target organisms.
Articles, citations, reports, websites, and multimedia resources focused on rangeland ecology, management, restoration, and other issues on rangelands around the world.
