Asia would be responsible for their disappearance, shows study that for the first time quantitatively demonstrates scale of illegal killing
Ivory consumption is unsustainable and is causing a dramatic decline in the number of African elephants, according to a new study, “Illegal killing for ivory drives global decline in African elephants”, published in the August 19 issue of Proceedings of the National Academy of Sciences (PNAS).
An estimated 100,000 elephants (Loxodonta Africana) were killed by poachers across Africa between 2010 and 2012, says the new study, led by George Wittemyer, professor in the Department of Fish, Wildlife and Conservation Biology at Colorado State University's Warner College of Natural Resources.
An average of 33,630 elephants per annum are calculated to have been lost over the three years to meet the increased demand for ivory, especially from China and other Asian nations, reveals the report. In contrast to the rest of Africa, this study concludes that central African forest elephants experienced decline throughout the last decade.
The study is co-authored by Joseph M Northrup, Julian Blanc, Iain Douglas-Hamilton Patrick Omondi and Kenneth P Burnham.
For the research, Wittmeyer used a recent analysis and data compiled under the CITES MIKE programme; it contributed significantly to this investigative study on the role of the ivory trade in elephant poaching. MIKE is a survey of elephant deaths, managed by the Convention on International Trade in Endangered Species (CITES).
More large-scale seizures
The most updated and recent analysis, titled “Monitoring of illegal trade in ivory and other elephant specimens, Dec 2013”, from the Elephant Trade Information System (ETIS) of CITES had also noted that illicit trade in ivory has greatly increased, reaching the highest level in at least the past 16 years. The frequency of large-scale ivory seizures (more than 800 kg) has also increased, indicating a highly-organized illegal ivory supply chain.
A unique research on elephant population in Samburu National Reserve in central Kenya, titled “Comparative Demography of an At-Risk African Elephant Population”, conducted by Wittemyer and published in PLOS ONE last year, was widely reported for its disturbing revelations regarding elephant poaching epidemic in Africa, and has provided key inputs and data for this study.
According to Wittemyer, “The real-world impact could be even direr than the [study] model predicts because poachers target the largest adults [for their bigger tusks], whose deaths decrease birth rates and disrupt social networks.”
He says his latest study is the “first study that explicitly and quantitatively demonstrates the magnitude of illegal killing and that the level of illegal killing is causing the decline of the species. He expects and hopes that his research is integrated into global policy decisions and is distributed largely and globally to those who are processing ivory. This will help curb the demand for this product.” (Watch George Wittemeyer speak about his work) Another report put together by by CITES Secretariat, IUCN / SSC African Elephant Specialist Group and TRAFFIC, “Status of African elephant populations and levels of illegal killing and the illegal trade in ivory”, reveals how unsustainably high poaching rates, which outstrip the birth rate of healthy elephant population, is leading to decline in elephant populations (see graph below).
|Key recommendations by Wittemyer and his team
The study confirms that elephant populations in eastern and southern Africa were in good shape until 2008, but then started to decline. Now, about 75 per cent of the populations across the continent are shrinking.
A report submitted by TRAFFIC, a wildlife trade monitoring network, at the African elephant summit in December 2013, also outlined the serious threat posed to African elephants from poaching and the illegal ivory trade while expressing concern over the range and habitat loss as a significant long -term threat to the species’ survival.
Earlier this month, a paper released by the Wildlife Conservation Society on August 7, too, found that corruption, organised crime, and a lack of enforcement makes any legal trade of ivory a major factor contributing to the demise of Africa's elephants. Hence, to save elephants, all ivory markets must close and all ivory stockpiles must be destroyed, it said.
African states in which the illegal ivory trade flourishes are making some efforts to curb the malaise. They came together at the African Elephant Summit convened by the government of Botswana and the International Union for Conservation of Nature (IUCN) in Gaborone in December 2013 and unanimously adopted 14 urgent measures to halt and reverse the trend in illegal killing of elephants and the illegal ivory trade promising to secure elephant populations across the continent.
CITES takes African nations to task
The CITES Standing Committee that met in Geneva, Switzerland (SC65) in July this year also took serious view of the matter. It took African countries to task for allowing illegal elephant ivory trade and asked them to comply and implement CITES-implementing legislation by the next meeting of the Standing Committee in August next year.
The CITES Standing Committee at Geneva this July that followed the African Elephant Summit in December last year, which focused on the dynamics of the entire ivory chain, and now the seminal study by Wittemyer sets the agenda for global policy decisions and points to the urgent need to curb illegal trade in ivory and save the African elephants. But implementation of any plan would require urgent and proactive action.
