To understand why these reasonable-sounding proposals should be rejected, consider what has happened to elephant numbers since CITES most recently authorised some legal trade, when Botswana, Namibia and South Africa were allowed in 2007 to sell a fixed amount of ivory to Japan, as a one-off. Elephant numbers started falling again. A survey conducted in 2014-15 estimated that elephant numbers had fallen by 30% across 18 countries since 2007; another estimated a decline of over 100,000 elephants, a fifth of the total number, between 2006 and 2015. Increased poaching was at least partly to blame.
These numbers suggest that the existence of even a small legal market increases the incentive for poaching. It allows black-marketeers to pass off illegal ivory as the legal variety, and it sustains demand. The biggest market is in China. Last year the government banned domestic sales of ivory, but its customs officials seize a lot of smuggled products—notably from Japan, which licensed as a market in 2007. For the poachers, ivory is fungible. If it is hard to secure in Zambia or Botswana, another country’s elephants will be in the gun-sights. Congo, Mozambique and, especially, Tanzania, have seen sharp declines. Unfair though it is, countries with better-run conservation programmes are, in effect, paying for the failings of those with feeble institutions.
That is from The Economist. Yet there is another twist:
In the long run technology can help make trade compatible with conservation. In better-resourced national parks, drones are used to make it easier for rangers to spot poachers. DNA testing of ivory shipments can establish where they came from, and thus whether they are legal. As prices fall and countries get richer, both technologies are likely to spread.
