The initiative comes in the wake of a recent scientific finding and European declaration that the traditional root drink is safe.
The coordinator of the FAO's awareness programme, Peter Napuat, has been conducting a week-long training and awareness programme about the plant.
He says there are many varieties of kava in Vanuatu compared to other countries in the region, and only ten varieties are suitable for local consumption and the export market.
Napuat says farmers need to be encouraged to only plant and sell those noble varieties.
