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...
متن کاملElephant Economics in the Rough: Modelling Ivory Trade
Trade in ivory is banned under CITES in an effort to protect the African elephant. The trade ban is supported by some range states, most notably Kenya, because they see the ban as an effective means for protecting a ‘flagship’ species, one that attracts tourists and foreign aid. It is opposed by some states, mainly in southern Africa, because their elephant populations are exceeding the capacit...
متن کاملLegal ivory trade in a corrupt world and its impact on African elephant populations.
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. High prices for ivory mean that th...
متن کاملCombating the illegal trade in African elephant ivory with DNA forensics.
International wildlife crime is burgeoning in this climate of global trade. We contend that the most effective way to contain this illegal trade is to determine where the wildlife is being removed. This allows authorities to direct law enforcement to poaching hot spots, potentially stops trade before the wildlife is actually killed, prevents countries from denying their poaching problems at hom...
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-...
