Ivory transaction index
Riccardo Pravettoni, GRID-Arendal
Overall, using weight and transaction indices derived from the
ETIS data, illegal ivory trade activity remained at or slightly
above 1998 levels up to 2006. Subsequently, a gradual increase
in illegal ivory trade activity commences, becoming progressively greater in each successive year, with a major surge in 2011. The frequency of illegal ivory trade transactions in 2011 was roughly three times greater than the level of illegal trade activity found in 1998. This applies to all categories of trade – both for raw and for worked ivory of either less than 10 kg; between 10 kg and 100 kg; and equal to or greater than 100 kg.
