The Database

The Agriculture & Food Systems Institute’s Global Environmental Zones (GEnZ) Explorer is a simple-to-use online tool that allows users to visualize agroclimatic zonations and their relationships to CFT locations. For any of the 20 included crops, the tool can identify environments at the country, regional, or global level that are important for cultivation to help determine where to best locate CFTs and maximize data utility.

The Need

Confined field trials (CFTs) are conducted to inform environmental risk assessments that are required by regulatory authorities before genetically engineered crops can be approved and released for cultivation. The primary variable that differentiates CFT locations is agroclimate, which means that data from trials cultivated in like agroclimates should be considered relevant and sufficient to satisfy regulatory requirements for CFT data, irrespective of the country where the CFTs are conducted.
