Threats to African elephants
The two main historical factors behind the decline of African elephants – demand for ivory and changes in land-use – still pose a serious threat to the species.
Most range states do not have adequate capacity to protect and manage their herds. If conservation action is not forthcoming, elephants may become locally extinct in some parts of Africa within 50 years.
Still poached for ivory and meat
In the early 1970s, demand for ivory soared and the amount of ivory leaving Africa rose to levels not seen since the start of the century. Most of the ivory leaving Africa was taken illegally and over 80% of all the raw ivory traded came from poached elephants.
This illegal trade was largely responsible for reducing the African elephant population from 3-5 million to current levels. In the 1980s, for example, an estimated 100,000 elephants were being killed per year and up to 80% of herds were lost in some regions.
The poaching was generally well-organized and difficult to control because of the availability of automatic weapons.
Ivory ban introduced
In 1989, CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) banned international trade in ivory to combat this massive illegal trade.
As the ban came into force in 1990, some of the major ivory markets were eliminated. As a result, some countries in Africa experienced a steep decline in illegal killing, especially where elephants were adequately protected. This allowed some elephant populations to recover.
But poaching continues
However, in countries where wildlife management authorities are chronically under-funded, poaching still appears to be a chronic, significant problem. Thriving but unmonitored domestic ivory markets continue in a number of states, some of which have few elephants of their own remaining. These markets fuel the illegal international trade.
Moreover, increasing land use pressures on elephant range (see below), declining law enforcement budgets, and continuing poaching pressure for bush meat as well as ivory, have kept illegal killing of elephants widespread in some regions.
Unequal distribution of elephants means different opinions on conservation
Considerable debate surrounds elephant conservation, largely because of the varying status of elephant populations in different range countries.
Some people, mainly in southern African countries where elephant populations are increasing, consider that a legal and controlled ivory trade could bring substantial economic benefits to Africa without jeopardizing the conservation of the species. Others are opposed to it because corruption and lack of law enforcement in some countries would make it difficult to control the trade.
