The ivory trade and elephant conservation
In response to significant elephant population declines in the 1970s and 1980s because of poaching for ivory, the Convention on the International Trade in Endangered Species of Wild Fauna and Flora (CITES) banned the international trade in Asian and African elephant species by listing them on Appendix I in 1973 and 1989, respectively. Many southern African countries disagreed with the African e...

Illegal hunting of African elephants (Loxodonta africana) for ivory is causing rapid declines in their populations. Since 2007, illegal ivory trade has more than doubled. African elephants are facing the most serious conservation crisis since 1989, when international trade was banned. One solution proposed is establishment of a controlled legal trade in ivory.

The demand however outstrips the supply and with soaring prices, illegal tusk harvesting is thriving on the African continent. Formal restrictions placed on trade in elephant products have been ineffective in reversing the rapid decline in elephant numbers. We are presently...
متن کاملProtecting the African Elephant: A Dynamic Bioeconomic Model of Ivory Trade
International trade in ivory is banned in order to protect the African elephant. The trade ban is supported by some range states, because it is seen as an effective means for protecting a ‘flagship’ species, but is opposed by states, mainly in southern Africa, because populations exceed the carrying capacity of local ecosystems. Issues concerning the ivory trade ban are addressed in this paper ...
متن کاملAssigning African elephant DNA to geographic region of origin: applications to the ivory trade.
Resurgence of illicit trade in African elephant ivory is placing the elephant at renewed risk. Regulation of this trade could be vastly improved by the ability to verify the geographic origin of tusks. We address this need by developing a combined genetic and statistical method to determine the origin of poached ivory. Our statistical approach exploits a smoothing method to estimate geographic-...
