"Status of African elephant populations and levels of
illegal killing and the illegal trade in ivory: A report to the African Elephant Summit, December 2013"
Factors associated with levels of illegal killing:
"The MIKE programme has statistically evaluated relationships between PIKE levels and a wide range of
ecological, biophysical and socio-economic factors at the site, national and global levels. Three such
factors consistently emerge as very strong predictors of poaching levels and trends: poverty at the site
level, governance at the national level and demand for illegal ivory at the global level. The quantitative
relationships between PIKE and these factors are illustrated in Figure 5.
Human infant mortality in and around MIKE sites, which is interpreted as a proxy for poverty at the site
level, is the single strongest site-level correlate of PIKE, with sites suffering from higher levels of poverty
experiencing higher levels of elephant poaching. This suggests that there may be a greater incentive to
facilitate or participate in the illegal killing of elephants in areas where human livelihoods are insecure.
Furthermore, this relationship highlights a close linkage between the well being of people and that of the
elephant populations with which they coexist.
At the national level, the strongest correlate of PIKE is governance, as measured by Transparency
International’s Corruption Perceptions Index (CPI). High poaching levels are more prevalent in countries
where governance is weaker, and vice versa. This is likely to be a causal relationship, with poor
governance facilitating the illegal killing of elephants and movement of illegal ivory, be it through
ineffective law enforcement or active aiding and abetting by unscrupulous officials.
Ultimately, the illegal killing of elephants for ivory is driven and sustained by demand from consumers
who are willing to pay for illegal ivory, as measured by household consumption in China. ETIS analyses
indicate that, in recent years, China has become the world’s largest consumer of illegal ivory. This is
corroborated by the fact that that temporal PIKE trends are strongly related to patterns in consumer
spending in that country. This relationship does not hold for other traditional destination markets for ivory
(Europe, USA or Japan) or for countries known to be important transit points in the ivory trade chain
(Malaysia, Philippines, Thailand or Viet Nam). Temporal PIKE trends are also strongly correlated with
another demand-related variable, namely trends in large-scale ivory seizures as reported by ETIS."
My take is while placing a ban on ivory does has some affects on limiting kills, it is not the only factor causing the reduction. I think it's safe to say it's not the controlling factor at all. The controlling factor is the Chinese economy.
So how do you explain elephant populations recovering between 1989 and 1999, when the trade of ivory was illegal? Just wondering. You know, seeing as you said making ivory illegal wouldn't save a single elephant. You're actually right. It saved thousands.
Are you people really this dense?
Argue with the numbers. Between 1989 and 1999, elephants went from "endangered", to "protected". That means there was an improvement in the population.
